Quite often, professionals and private developers face the challenge of floor alignment. If the rough surface has an impressive difference, then in the future the geometry of the room will be broken, therefore it is necessary to take care of creating high-quality floor. For this, different technologies are used today. However, as one of the techniques, the one that provides for the installation of adjustable supports for the lag.

Why choose adjustable supports

The floors on adjustable lags have many advantages over other technologies, among them should be allocated:

• minor weight;
• the possibility of carrying out fees insulation;
• speed of work;
• no need for a special skills in the master;
• the possibility of forming a multi-level floor;
• the possibility of laying outdoor coverage without installing the substrate.

Lugi are installed on the draft coating. The distance between them should be due to the characteristics of the future floor. Through each anchor, it is necessary to drill holes in a concrete or a wooden beam, there at the next step is installed self-tapping screw or dowel-nail. Now you can perform alignment using a level. The protruding parts of the bolts are cut, then you can start styling a rough array.

Regulating anchor do it yourself

If you decide to install metal adjustable supports for lag, you can perform an anchor alone. All items should be purchased at the Building Materials Store. For an adjusting device, prepare:

• studs;
• scoring anchor;
• nut;
• metal plate;
• washers.

The plate is fixed to the heel with a bolt and nut. With the help of the latter, the adjustment will be performed. Another nut with a bolt is necessary for fixing the bar from above. In order to install the nut, the groove should be made in the lag so that the element does not interfere when the laying of the flooring will be accomplished.

Adjustable support on heels and corners

If you do not want to purchase finished fixtures, then you can install floors on the heels. The price of the structure will be lower, and according to the characteristics the floor will not give way to the one that is assembled using ready-made structures. If you use the corner, they should be firmly strengthened to the base. This method is suitable for those cases where the use of studs is impossible. The fastening of the lag is carried out according to this technology when the draft floor has a weak base. The size of the corner will depend on what level you want to lift the surface.

If you install adjustable supports for lags, it is important to place points for which the holes in a bar under plastic bushings will be drilled. To drill the first hole from the edge, 10 cm should be retreating. The distance that will remain minus at both ends must be divided into equal segments. Between the side plane of the first lag, ends and walls need to leave the distance.

The step between lags should be the same. Private lags are located so that the edge of each of the sheets of plywood relied on the bar. There should be a centimeter clearance between the plates. By installing regulated supports for lag, in the planned points on a bar, you should form holes for the supports, which are then screwed by screws. Only extreme bolts are installed flush with a plane, it is using them to be adjusted.

Conclusion

As soon as the lag with the sleeves will turn out to be in its place, through the internal cavity of the sleeves, it is necessary to outline the points for the installation of a dowel-nail. After lag, it is removed, and the holes are drilled in the concrete points. It is necessary to deepen on 5 cm. Lag returns to its place, and fasteners are inserted into the bolts.

It knows that in order to align the floor level in the apartment there are several of the most common ways. And one of them is to use adjustable floors. The use of concrete screed gradually loses its popularity. These works require significant efforts, and also assume the presence of dampness and dirt. Especially for the installation of adjustable floors, it will take a lot less time.

One worker per day can independently put the floors on the square up to 20 square meters. m. Then we will tell more in more detail about the advantages, disadvantages and features of the assembly of adjustable floors.

Design features

To understand what regulated floors should be familiar with their principle of action. Studs rotate around their axis, which allows you to adjust the floor level horizontally. By the same principle, floors work on plates, which are also moved due to rotation. This allows you to set the floor as accurately as possible. You can align the floor horizon almost perfect.

Such structures will not become exhausted under weight or "play". You can install them on any available surfaces. On each floor you can impose several layers of coating (plywood).

Such floors will become an excellent solution for sports halls, clubs, office premises, and so on. Due to the amplification of carrying spills, the load indicator (up to 2 tons per 1 sq. M. m) can be increased. The service life of adjustable floors is up to 15 years.

Features of use

Adjustable floors most often apply:

• At stations and rooms for server location;
• Under the final finish in the maximum deadlines;
• In the houses of new buildings;
• In houses of old buildings for overhaul or reconstruction;
• To increase the level of sex for a sufficient level (especially when additional pressure on the main floor is undesirable);
• When installing multi-level floors;
• To carry out under the base of the floor of all sorts of communications.

If you need to align or lift the floors to a significant level, the use of adjustable floors will become an excellent solution. After all, it will take a month for laying a concrete screed, while with adjustable floors you can handle over one or two days.

Also, the use of such systems will be useful in homes, where under the floor specially left a distance of up to 15 cm for laying communications or insulation. Not all designs can withstand the load of such a layer of concrete. But the use of adjustable floors will help you raise the coating level up to 20 cm.

You can also successfully, for example, transfer to the plumbing (toilet or bathroom) and hide bulky communications not under a thick layer of solution, but under the floor where they will remain available at any time.

Especially popular use of such systems for country houses or cottages. So you are given the opportunity to hide all communications in one place, where they will be reliably protected from exposure and are available at the earliest.

Pros and cons

As with any such systems, there are also its advantages and disadvantages.

Benefits:

• One worker can install the adjustable floor during one working day;
• The system of adjustable floors is lightweight in itself, so it will not be able to additionally put pressure on the main floor;
• International testing confirm the quality, strength and durability of such systems;
• Using adjustable floors, you can additionally insulate the room from sound outside;
• You are given the opportunity to use the floor to hide all communications, which is a plus not only from aesthetic point of view, but also safely collects them in one place;
• Maximum accuracy when placing horizontal floor level;
• Various levels that can be used in parallel (up to 20 cm);
• Materials that are used for manufacture are tested for purity;
• There is an opportunity to quickly correct the irregularities of the floor, even if there is a 10-15 cm inconsistency;

Such a system is distinguished by durability.

Disadvantages:

• Over time adjustable. To avoid this, at the installation stage, it is necessary to remove all dust and dirt after drilling holes and clogs of dowels. It is best to use a vacuum cleaner for this. Also thoroughly clean the first surface of the floor before laying the second layer. Controls so that all the dowels and nails are clogged to the end. It will not allow the design to fall out. It is also necessary to take into account that the tree is a natural material that breathes and is able to deform under the influence of moisture or gravity. Over time, the symbols, one way or another, will manifest;
• If you raise the floor level for a long distance, then when walking on it will be heated. For example, the sound from women's heels will remind a blow to the drum. Installation of additional sound insulation will help correct the situation.

All your work depends on the quality of the materials used. Take their choice with special attention. High-quality bar and plywood will get rid of you from the need to dismantle the floor in the future.

For maximum accuracy when setting the floor level, use a laser level.

Take care to ensure proper ventilation under the floor covering.

Types of adjustable floors

Depending on the type of design, adjustable floors are divided into two groups:

• plates;
• lags.

With the help of adjustable plates, you can lift the floor for a distance of no more than 3 cm. This is a bit, but enough to carry out the necessary communications: telephone, internet and so on. You can also pave heat-insulating and sound insulation materials under such floors.

Such structures are sheets of thick plywood (you can use a few of its layers). Special sleeves are inserted into it. The peculiarity of these sleeves is that they already provide a special internal thread. It has an anchor for an adjustable floor, which will serve as a level regulator. Then the whole design is installed on the base and is fixed by dowels.

As already mentioned, the difference between such a system is that the adjustment of the floor level occurs directly through the holes in the stove (from plywood or any other suitable material).

To assemble the floor based on adjustable slabs, it is enough to adhere to our tips:

• Drill holes in plywood sheet;
• Then insert the sleeves in them, on which the thread from the inside is pre-screwed;
• Insert special bolts into the sleeve, which will adjust the plate level;
• Fix the bolts to the base;
• Turn the bolts until the ideal flat floor plane do not achieve;
• After that, the remains of the bolts that look out over the surface of the plates must be cut off with a grinder;
• The final stage of the assembly will be the laying of the next layer of plywood, which will hide traces of bolts.

Note that when laying a new floor layer, its seams should not coincide with the seams of the previous one, because the design will not be durable.

Adjustable lags for the floor today are the best alternative. When using such a design, the floor will be raised at least 5 cm. This distance can be successfully used to insulate the room from sound or smells, as well as for laying all the basic communications of the apartment or at home.

Such structures are highlighted by simplicity and speed of assembly, as well as reliability and durability. Lag is equipped with special sockets for installing bolts. It is fixed to a special base with a dowel. To change the floor level, it is enough to rotate the bolt in the desired direction. After complete alignment of the plane of the floor, the coating is superimposed on them.

Such floors are often used in the buildings of the new construction of high comfort, in which the gasket of all major communications is made under the floor.

The main advantage of such systems is their robust fixation to a wooden or concrete basis. Other materials can be used as a base. For example, a thread anchor can be installed on concrete slabs, hollow inside, wooden bars with self-tapping screws, as well as brick surfaces with a concrete tie with special mounts or to the wooden floor.

To properly assemble such a design, check out our instructions:

• In the nest in the lag, special racks (bolts) are installed;
• Now decompose lags around the perimeter of the room and inside it. Here it is necessary to take into account the required strength of the design to a sacking, which depends on the type of floor coating used. For example, the distance between the lags should be about half a meter. If you use floor tiles, then keep the distance to no more than 30 cm. To ensure the necessary air circulation, step from the walls one centimeter;
• Then through the holes provided in the lags, drill in the floor for installing bolts. Their depth should not exceed 4 cm;
• Next, you have to set the floor covering at the required level. Note that the difference in the parties should not exceed 1 mm. To regulate, use a special key that turn bolts;
• After placing the floor, hammer the protruding parts of the dowels or cut them with a grinder or chisel.

Next, the installation of the floor covering is performed. To begin with, use two layers of waterproof plywood. The first layer is secure with self-tapping screws straight to lags. The following layer of plywood should be installed with a slight deviation from the first so that the joints do not coincide. In the case of using floor tiles, waterproof drywall is better used as the second layer.

To hide the irregularities and gaps between the floor coating and the walls, use the plinth. Specialists in some cases are recommended to establish them after all finishing works.

As you can see, the adjustable floor on the hairpins or on the plates is a rather successful alternative to a conventional concrete tie. Moreover, it is not necessary to have special construction skills to install such a design. It is enough just to be patient and do everything according to the instructions. If you have ever come across the problem of installing such systems, share your comments under this article.

Tips for installing structures with adjustable support

Modern floor options include adjustable floors of the last design.

The daily system installed on the mobile brackets makes the surface of the floor completely smooth with minimal physical effort.

Manufacturers produce several versions of the so-called "adjustable floors", depending on the purpose of the specific space, the estimated height of the floor coating and the state in which the substrate is located.

If it is necessary to raise the floor level to the desired height so that various communications can be placed under its surface, you can install the DNT structure with adjustable leg supports. They provide not only the perfect homogeneity of floor coverings of all materials, but also allow you to install the frame when the floors between the floor in the house are wooden elements.

The upper form is capable of lifting the coating to a height of 5 or more centimeters, which depends on the cross section of the logs and sizes having polymer screws. The system can be attached to a wooden or cement floor or to another type of foundation.

When it is necessary to solve the problem of aligning coarse soil, without losing the height of the space, you can adjust the adjustable lower structure on the plates.

It is used to prepare the base for laying, for example laminated or parquet panels, provided that the difference in height does not exceed 2 mm with 2 linear meters. The maximum amount of lifting floor covering in this case does not exceed 5 centimeters, which corresponds to the thickness of the standard concrete screed.

The parameters of the adjustable DNT structures allow for a short time to create a durable and durable floor, characterized by excellent thermal and sound insulation of the room. In this case, there is no need to engage in dust-shaped and wet processes, as in the case of the installation of cement sand. The cost of the DNT system does not exceed the prices of traditional alignment options, such as semi-dry or concrete ties, as well as floor coatings KNAUFF.

If the soil rises by 5 centimeters or more, you can save a large amount when preparing a rough base for finishing.

Disadvantages of regulated floors

As for the shortcomings of this project, they may arise if the requirements for appropriate work were not performed during installation.

Adjustable DNT floors with high-quality installation becomes a reliable and durable base for all finished floor materials. It will not only be the opportunity to move on foot, but also go by car.

In case of violation of the assembly of the DNT system or incorrect type of fasteners for the adjustable soil flag will become unsuitable for use for a short period of time.

Characteristics of adjustable soil on logs

The structural solution of such floors has the following characteristics:

1. Perhaps with your own hands to create adjustable floors on the logs without experienced masters.

   How to make adjustable floors

   You just need to buy high-quality materials and delivery of some tools.

2. Floors will not exceed one or two days. In exchange for dry concrete, you will need about a month.
3. Adaptive design allows, if necessary, establish engineering communications in technologically free space.

   This saves space and at the same time impenetrable flooring.

4. With the help of an adjustable system, it is possible to significantly increase the soundproofing in the room, so in recent years such floors have been installed not only in residential buildings, but also in recording studios and concert halls.
5. Just weigh similar structures to use them successfully in places where they are poorly covered, for example, in private houses or on balconies.
6. In the process of adjusting the adjustable floors, there are almost no works associated with dust and mud.

   That is why this option is the perfect solution for the areas where purity is required.

7. As shown in the figure, the adjustable floor system is capable of carrying a load of about 2.5 tons per square meter, which means that it can be installed in offices of various purposes - office, residential, warehouse, commercial.

The possibility of selecting adjustable soil

Although regulated structures have many advantages, many real estate owners doubt the possibility of their installation during repair.

• if a rough base is difficult or cannot be resolved because it has great differences and disadvantages;
• when aligning the substrate for many technical reasons, you cannot use high weight materials;
• If the floor covering should be created with different heights;
• when engineering communications should be placed under the ground;
• if there is a need for additional noise and thermal insulation.

Types of floors with adjustable brackets

In the modern market, consumers are offered two types of flooring:

• Construction containing adjustable flooring;
• outdoor systems with adjustable brackets.

The main difference between these varieties is the difference in height.

When installing systems on the logs, the amount of lifting is 5 centimeters or more. As for the adjustable design on the plates, it can be raised to a maximum of 3 centimeters.

Installation work related to installing adjustable systems on logs and boards is performed using similar technology that allows you to do it yourself.

Floor design with adjustable flags

Prints for them are made of planned rays.

The size of the wooden elements usually does not exceed 50 × 50 centimeters. First you need to prepare tools and building materials.

To install the floor, you need:

• lags behind the rods;
• level;
• polymer screws;
• nails with dowels;
• a hammer;
• drilling.

Preparatory work is carried out at the first stage:

1. Clean the base.

   If necessary, build engineering communications.

2. Tighten the screws of wooden screws. In the presence of threaded holes on the rods in them, the screw is screwed into the stand for adjustable logs.

   Otherwise, they must be performed independently. At a distance of 2 meters, at least 5 holes should be made. This simple operation is performed by drilling with an extended top. For the hardness of the installation, it is necessary to drill a little less than the diameter of the bolt.

3. After manual tension, tighten the screws with a drill and a special nozzle.

At the installation phase, the following measures are performed:

1. Wooden sticks scattered on the ground.

   In this case, the difference between them depends on the type of floor area. When the floor plan is covered with a linoleum or stove, the distance between the beams should be up to 30 centimeters. Leave at least one centimeter at a distance between flags and walls to ensure the necessary ventilation.

2. When the adjustable log setting is completed, proceed to the hard mount of the screws to the rough surface. Take the hard drill and make a hole with a length of about 4 centimeters through the pin in the concrete.
3. Then the spindle was fixed in it and driven by a hammer, fixing the bolt on the floor of the floor.

   The hole must be securely enshrined so that the design is not mobile.

In the process of smoothing the surface:

1. When adjustable full clamps are installed around the perimeter of space and securely secured, they begin to repair them.

   This applies the rule and key to be adapted.

2. Let's break to the height that should not exceed 1-2 millimeters. Using the key and focusing on the measurements, we start lifting or lowering the screws that seek to ideal alignment.

At the final stage, follow these tasks:

1. When adjustable flags are aligned with their own hands, nails are finally fixed with a hammer.
2. On racks that are cut by knife or other tools for cutting out unnecessary residues.
3. Where it is necessary, sound or heat-insulating materials are placed between the logs.
4. On logs, or better from above, correct the floor.

   The choice of materials depends on the purchased flooring. Typically, the floor is made of plates made from plywood, rarely using DSP or GVL plates, on top of which are linoleum or laminate.

5. Directly on the floor for the adjustable installation of the final coating floor.

Outdoor coatings with adjustable supports

This option is used if the height of the floor surface does not exceed 3 centimeters.

In such a narrow space, you can hardly hide communication, but a telephone cable and Internet wiring will be available. The technology of installation of this type is similar to the procedure for installing adjustable floors on the logs.

It is necessary to prepare a set of adjustable presses on plates consisting of plywood sheets (other building material), pillars, bushes, self-tapping screws.

You will also need: hammer, drill, level (water or laser).

Work begins with the preparatory stage:

1. Prepare the work surface, remove the garbage, dust, contamination. Then divide the messages to be removed under the ground, not forgetting that the height of the floor surface should not exceed 3 cm.
2. Leaves are located around the perimeter of space at a distance of 2-3 centimeters on each side.
3. Mark the points for drilling holes.

   If it has a sheet of 1.5 × 1.5 meters, it should be approximately 9. One of the holes should be placed in the middle of plywood or other material. Four holes rotate in each corner and 4 in the middle of the sheet. For this reason, you can provide a reliable compound of plywood.

Installing panels must be performed in the following order:

1. After labeling holes on the plates, they begin to drill.

   Use a special drill with an extended tip.

2. In already prepared holes, there are screws with gaskets, and on the bottom side they attach bushings using self-tapping screws.
3. When the screws are inserted into each of the holes and secure, the sheet is facing and placed on the design.
4. Using holes for screws in the hole, drill holes and insert the dowels in them.

   They lead them halfway.

At the adaptation stage, the following measures are performed:

1. When the adjustable support is installed, sheets are aligned. This work is performed using a level and a special key.
2. After decoration, carefully cut off extra centimeters.
3. Inch nails are fully driven into the base.

Go to the final stage:

1. If there is a need to improve the noise and thermal insulation of the soil, suitable materials are placed in the top of the sheet.
2. After the sheets are collected, the selected flooring is installed.

Tips for installing structures with adjustable support

To successfully install this type of floor system, you need:

1. When the adjustable brackets are completed, it is necessary to clear the base before laying the floor.

   The fact that crude garbage, plastic cutouts, sawdust after the last flooring can lead to the appearance of pulleys and noise.

2. All fasteners for the design of the floor should be carefully knocking and tighten, as it depends on the strength and reliability of the system.
3. Experts recommend to mount both the fastening element and an anchor for the adjustable floor.

   This is the same dowel, but stronger. Anchors provide reliable and constant binding. They not only hold a stick in place, but at the same time attract it to the ground, which in addition to rigidity also transmits stiffness.

4. When the high floor is arranged, the best solution is to put the wrists from the soundproofed materials.

   During the work, noise did not arise.

5. You do not have to save the quality of the goods if you want to create an adjustable structure. With the financial side it will be more profitable to immediately buy an expensive component than to process all the work again.

If you need to move the connection after the installation is completed, several coverage strips can be deleted and then return.

Adjustable floors

Often, the floors on the lags are caused by the people of the association with something old, a creamy, rotting and morally obsolete.

Of course, there are currently many advanced technologies for floors that allow you to warm, waterproof and raise the floor level for a large height if it requires idea. However, one should not exclude old, good lags - the solution has simplicity and with high-quality installation will exclude deficiencies typical for such floors.

Advantages of adjustable Lag.

The most indisputable advantages of adjustable floors are the ability to raise the floor level on a large height without weighting of the total weight of the design and speed of installation, in comparison with various ties and bulk.

A big advantage is the lack of wet processes and therefore, no need for drying. The insulation of such floors does not cause any problems - foam, extruded polystyrene foam, mineral wool, all these materials are acceptable. In comparison with bulk, floating screeds to the insulation, high demands on the density of the insulation, and it is possible to choose budget material.

When pouring a screed, thickness up to 5-10 centimeters, the benefits of the lag are not relevant, however, there are often situations where the floor level should be raised by 15 or more centimeters. Such heights may be required with a large overlap slabs, with partial repairs of the apartment, where you have to stick with the old floor on the lags.

Of course, there are ties with the addition of claympsit, various floating screeds that allow you to raise the floor level and at the same time inspiring.

As a rule, the cost of materials and work increases and if the screed in 5 centimeters is 1.5-2 times cheaper than the adjustable floor, then with layers of more than 10 centimeters, the cost of lag remains the same, which cannot be said about wet tie.

disadvantages

The laggards of lags on lags include the risk that the floor creaks, in an aggressive, wet environment, the tree is not so durable. The issue with creak is practically reduced to zero when choosing high-quality, dried lags and the right fastener.

Many confuse the possibility of laying the tile of such floors - this problem is solved, the lags are set in sufficient quantities in order to eliminate weighty devices in the canvas, on top of the canvas harrowing is harvested.

Hypus fiber serves as a damper, with a large fluctuations in the size of the canvas from changing moisture, GWL is fairly stable and does not provoke the tile for declining.

The material of the canvas stacked by lags is quite diverse: from the budget chipboard and ending with plywood in two layers. Planed boards, lining and OSP - Agree, a very wide choice for sex by lags.

How to make a smooth floor on adjustable lags do it yourself

RESULTS

Let's summarize: in repair, where standard screeds and bulk floors do not cause high loads on the overlap and the layers are quite thin - adjustable lags are not relevant.

In the same place where it is necessary to raise the floor level by 10+ centimeters, the lags become a very practical solution. Qualitative installation is important, it will prevent the creaking, seating and other, characteristic of wooden floors of the problem.

Independent installation of adjustable lag

Companies involved in regulated floors exaggerate their professionalism and the uniqueness of their technology. I will try to dispel some myths, for it worked in this area for several years.

Consider important moments in the installation.

Anchor, fasteners

For fastening the lag to the concrete base, it is an anchor, plastic dowels are not able to cope with the loads that lags are subjected.

The so-called plastic sleeves, which are screwed into the lag and are attached to the concrete are very uncomfortable in the installation, they can only be bought from those who are professionally engaged in installing floors. Naturally, very expensive. In addition, they have dubious reliability, the sleeve is attached to the concrete base on a dowel-nail.

The most reliable fasteners can be assembled independently, contrary to the cunning marketing of the "Genvy Companies". In this case, constituents for the rack are usually available in most shops.

So, homemade fasteners for adjustable lag. The basis is a spacecraft anchor (scoring), it tight keeps in concrete and easy to install, it is steel or brass, the anchor expands due to the twisted bolt.

Brass is preferable. The product is suitable for the M10 or M8 thread, the other components are selected based on the selected diameter. The next element is a bolt suitable with a diameter to an antera and the corresponding length, the higher the lags should be raised - the longer. Instead of a bolt, you can take long studs and cut them into the desired length, however, a special tool is needed to screw the studs.

Two nuts with washers (preferably enhanced) are screwed to the bolt, actually between these nuts / washers and the lag is clamped.

The resulting fastener is very reliable and convenient for use.

He does not pull it out even if the lags were from raw wood, the lag leads when dried, and the anchor holds.

Lagi

Typically, a 40 mm bar is used, but if it allows the height, you can take the lump thoroughly. In thicker bars, fasteners can be used less frequently.

Standard 3 meter lag is attached to 7 anchors. Lags are exhibited with a 30-40 cm spare, depending on the material of the covering sheets.

Lags should be chosen and without too large beggars and screws. The worse the lag succeeds, the greater the likelihood of a screen in the future. Ideally fit dry, planed bars, planed after drying, but it's not always easy to find such. Usually, the stores are sold planed to "raw" and then dried naturally bars, they have a bent shape. You can use them, but it is necessary to choose those that are smaller.

I note, lags do not have to be planed and smooth, in priority direct and not "screw". Also, knots should be avoided if the hole with an anchor falls on the bitch - the lag will significantly lose in strength.

Prepared lags can be treated with antifungal composition, it does not prevent potentially wet rooms.

Than to cover lags

Materials can be diverse, from rough to finishing. Under the subsequent finishing finish, you can lay a conventional cutting board - this option is more suitable for a private house.

The leafy materials are suitable for both private and apartment buildings. It can be plywood, chipboard, OSB. All these materials are considered black, with subsequent laying of linoleum, laminate and parquet board. With an additional flooring of the gypsum, a tile is placed.

The finishing coating includes the floorboard, lining.

Further, their finish is grinding and painting (although it is often useful to make it up to installation).

From the sheet material I want to celebrate Phaneru - it is durable, durable and tolerates moisture well. Due to the different orientation of the layers of veneer, plywood is less susceptible to "walking" in size.

There is truth, one is not a pleasant drawback: In most cases, the thickness of the sheets can differ slightly by 1-2 mm, and the difference may be present at different ends of one sheet. Because of this difference, for example linoleum, for example, we will have to put the seams. However, despite this, plywood is considered the best material for adjustable floors - 10 mm plywood in two layers of the durable solution.

In one layer there is plywood no thinner 18 mm.

Preparation of the foundation

To reliably fix anchors, a concrete base is required. Usually, in commercials, fasteners for lag are installed in the perfectly aligned cement-sand tie (CPS). But the reality is that for real work, the leveling of the base is not required. This time, besides, usually the screed does not have sufficient strength to securely hold the anchor.

If in your case the installation will be made for any reason on the CPS, then it should be brought up to concrete. Or check the strength of your screed by twisting the trial anchor.

Preparation lies in cleaning, fossing and lubageing of various slots, to avoid drafts. Also, it is necessary to place the location of future lag, it is done on the walls, where the middle of the lags will be. When marking should take into account the centimeter gaps of sheets from the walls so that the seams clearly fall into the middle of the lags.

It is easiest to make a markup so: since the lags are labeled, on which there will be sheets of sheets, and only then between the seams, the remaining laugs are distributed so that the distances between them do not exceed 30-40 cm.

I want to note: usually all lags are made parallel, on perpendicular lags of seams of compounds of additional lags is not required, about this next. Of course, lags can be set as you like, there may be longitudinal and transverse, the meaning is that it is not necessary to make extra crossies.

Montage Lag.

At my experience I was convinced: drilling holes for bolts and sweat for nuts more conveniently in place. If you make holes with sweating in advance, it is excluded the ability to move fasteners, it may be necessary when the fasteners get into a weak place in concrete, in the bawdy hollow and so on.

This my personal opinion is definitely you can chop holes in lags in advance. I will describe my method, but to solve you as more convenient and more practical. This method is not relevant with finished fasteners purchased in online stores - there for fixing anchor need to tighten the lower nut.

Lag is placed on the place marked, the perforator, right through the lag the hole in the concrete base is drilled. Drilling, immediately inserted anchor without washers and nuts. It will not let the lag be shifted with further drilling. I want to notice, in the panel and monolithic houses in most cases the thickness of the overlap is not more than 10 centimeters, so it is not possible to drill more than 5 cm, we are careful! Drilling, you need to clean the hole in the same perforator in drilling mode so that the whole crumb climbs out.

Thus, all lags are awarded, the bolts are delayed in anchors. The fastener is securely fixed in concrete, but the lags have a free move up-down.

After tightening the anchors of the hats of bolts spill, the lags are turned around.

At each sticking pin, they screw over one nut and put on one puck. Screw the nut on a cut bolt is not easy, so it is useful to have a small file at hand, overpowing the sawyard the nut to wind easier. Further, the lags are drilled by the upper nuts, wear back to their places, the lower nuts regulate the position of the lag and attract the second nut with the washer from above.

Lag regulation is most convenient to produce with a laser level. For tightening the upper nuts, a tubular key is convenient for regulating the lower - Rozhnik.

After all adjustments, the studs sticking above the lag spill. Installation of lag completed. If insulation thought - a layout and propagation of the insulation is made. Surplus foam is cut and the floor is ready for flooring.

Floor flooring

The most important thing in the flooring is to align the sheets so that the seams fall into the middle of the lag. It may happen that the seams will be significantly shifted if the sheet does not enter the lag at least on a centimeter, you will have to change the layout of sheets or make additional seams, to twist the lag is much more problematic. Sews going across the lag are tightened from the bottom between themselves BRA or the same sheet material.

It is important to leave 5-15 mm Clearance from the walls, the canvas will be expanded in the case of what, this will allow in some cases to avoid the edge of the floor.

At the flooring of plywood, an unpleasant phenomenon may occur: the screws may not be treated in the canvas and burst, it turns out not a tight attraction and the creaking may appear in this place.

At the site of the burst screw, you need to spin a new one, retreating several centimeters. If the tapping screws are bursting too often, the output is two: take it instead of 3mm screws thoroughly, for example, 6mm, or before twisting, do sweat a drill, a little big than the diameter of the Hats.

So everything seems to hope I gave comprehensive information.

Wooden floors are the warmest, eco-friendly and beautiful of all types of sex, because:

• the tree has a fibrous structure, it has, at the same time, strength and flexibility, as well as relatively low thermal conductivity;
• a tree is a material that "breathes", that is, absorbs moisture from the environment and gives it back, optimizing moisture in the room;
• it has a unique invoice that "plays" when skillful processing: due to the difference in densities, colors and pattern.

There are certain design features of the festival flooring.

This laying of lag - wooden bars - on a carrying structure with a certain step. To understand how to make the floor on the lags and choose the most suitable option for specific conditions, you need to find out what kinds of wooden floor designs.

In private house-building, various materials of carrier and enclosing structures are used, they are built on different types of soils than the choice of the foundation is determined.

Since the house is erected soon, the question is solved, how to install lags so that the floor is durable and stable. It will depend on the size of the room, since even for a room with an area of \u200b\u200b1x1 m, you need a support for lags in the middle. Therefore, it is necessary to decide, choose the support poles or the foundation of intermediate walls as a base for lags.

Installation of floor on lags on beams and reference pillars

As a support for Lag, the basement from the beam is satisfied with the inner perimeter.

For support between beams every 500-600 mm, intermediate posts are arranged. Technologically, it looks like this:

• The pit is digging, it will also serve as a formwork: 400x400 mm and 400 mm in depth.
• At first, the sand is trambed - a layer of 10 cm, then rubble - 10 cm.
• Then a layer of 20 cm poured a solution.
• When the foundation is ready, a column is laid out of a ceramic brick on it to the level of lag.
• From above, under lags, waterproofing is placed on the pillar.

Lags are stacked by leaning on the bars around the perimeter and pillars, between them, so that their ends come to the base wall or frame for 2-3 cm (this is necessary for the extension of the tree).

Lags must overlap the support at least 10 cm.

Scarlet is the top of the foundation of the house. It can be "low" - somewhat recessed relative to the "zero mark" - the level of land. Or "high" - raised above the ground. If the foundation is pile, Ruralka is made to bind individual columns - piles into a single design and in order to serve as a foundation for intermediate walls of the house.

The logging section, depending on the load, rendered to the floor, will be 10x20 or 15x20 cm.

Their lengths, preferably, should be enough from one to another wall of the room.

The step between lags will depend on the width of the insulation used - this will make the laying process more convenient (optimal size 1 m).

It is believed that lags before the attachment should be seen in the room for several days and only then they can be consolidated.

Before making the floor on the lags, communication between them can be paved.

It is necessary that the insulation is lower than the level of the lag at 5-7 cm.

It is necessary that a gap for ventilation remains between the insulation and layer of the first floor. The dimensions of the insulation and the lag should be better calculated immediately to comply with the technology (layer of the insulation can be 10-15 cm).

If the altitude of the lag is not enough for the ventilation device, they can be tied up the counterbours, which must have the same width as lags.

Algorithm of floor device algorithm

1. First beams, then the lags are attached to the base of perforated (anchor) corners, stacked on them.

   Self-tapping screws are used for the attachment. 3-4 cm long.

2. Along the lag, the cranial bruks of 4x4 cm cross section are attached to their lower edge. They serve as a support for boards or plywood (rough floor), which will be laid insulation.
3. Before laying the insulation of the board and lags, it is necessary to cover with a layer of high-quality waterproofing, with a wall at the wall, to the level above the first floor, so that the moisture from the underground space does not get into the insulation. Fixed waterproofing stapler to wood.
4. On top of the underlined insulation and the lag, the layer of vapor barrier is applied, which should also be output to the plinth level.

   It is tightly pressed against the insulation and is fixed by the stapler to the sidewalls of the lag.

5. The pile floor is laid on the lags. It can be a boardwalk and will be laid across the lag. If it is supposed to be placed parquet, a laminate or other sectional floor, it should be placed under it: wood-chip, OSB or cement-chip (CSP), which have sound and thermal insulation properties.

Between the fines of the first floor and the wall need to leave a gap of 1-2 cm, left on the temperature expansion of wood, which will then be closed by a plinth.

To ventilate the underground space with a laptile base, it leaves holes for bloods, which d.

b. Closed with protective nets, from rodents. In the summer, the purpose of the ventilation and drying is achieved, but in the frost, the subfield is very getting out, cooling and gender too. Therefore, the product is recommended for the winter.

A more appropriate option when the base is insulated from the inside or outside, and the ventilation is arranged internal - the channels are displayed and hidden behind the plinths.

Installation of floor on lags by intermediate walls

It differs from the mounting on the column design of the foundation.

The ribbon foundation is arranged under each wall and, thus, breaks the solid space of the basement on separate rooms.

All installation actions are repeated, only lags will rely on the foundations of intermediate walls or beams, attilened to them.

Because the influx of air for the ventilation of the underground, it is difficult to organize in intermediate rooms.

For the free passage of air in the walls, end-cutting holes are made, and ventilation channels, taking air from the room, are laid in the design of the enclosing walls.

Installation of floor on lags on the slab overlap

It is clear that to air from the bottom, in this case, it is not necessary, as is the flooring of the draft floor, as a substrate under the insulation.

Adjustable floors do it yourself

But to arrange sound insulation and, at the same time, insulate, it is still necessary. The better it will be done, the warmer will be the floor and the less voices and the sound of the perforator coming from the lower floor will be heard.

Lags are stacked in parallel short side of the room. Their size depends on the layer of the insulation, which is supposed to be put under the floor.

If the slabs of the overlap are not quite even, the horizontal of the lag can be achieved using the level and lining under the lags of plywood.

The cavities between lags are laid by the insulation or fall asleep, for example, clay.

On top of the insulation, a sheet of polyethylene or insulation of the type "Penophol" is placed, which will reflect heat inward and is attached to the stapler to the sidewalls of the lag. The remaining space of 1.5-2 cm will serve for ventilation of space under them.

Then, the lags are satisfied with the purple floor, with a mandatory device of the gaps between the coating and the wall.

Fastening adjustable Lag.

Quite often in the residential premises, the floor is organized on the lags, which allows you to apply any kind of insulation and noise insulation, various materials for roughing.

Thus, you can do any surface to do smooth and pave the necessary communications under the floor. Installation of this floor is performed simply enough, and from an economic point of view it is not very expensive.

As a result, a design with a small load on the base is obtained. And of course, when installing such a floor, the question is born, and whether it is necessary to fix the lags to the floor and, if necessary, how to make it, how to fix the lags for the concrete floor.

In this article we will give answers to these questions.

Fastening the lag to the floor: for and against

According to the completion of opponents of the attachment, these actions can destroy the screed, and where the bars and the base are connected, sound insulation is disturbed, and sound bridges are formed, which neighbors will not be reached.

And those who believe that fixation is necessary is shared by their experience: all the work done on the repair of the floor was in vain due to the deformation of the lag.

Is everything really saying? Regarding the destruction of the screed, if the screed is rather durable, then split it with a drill, it will not be possible to drill the hole.

And you can do the repair of the floor only with a solid foundation. If the former screed has become collapsed, then it must be removed.

The problem of sound insulation disturbance remains controversial.

Hard structures can actually transmit sound. However, insulating material is placed in the space between lags, which has sound insulating characteristics. Under the lags are a gasket with shock-absorbing properties, which also prevents sound distribution.

Sound bridge, which is formed at the fastening site, transmits fluctuations in concrete, and it is a sufficiently dense material and, unlike the tree, it does not spend the sound.

Consequently, for the neighbors, changes in the noise level will not be noticeable before repairing and after.

The floor on the lags is constructed from the bars, fasteners, roughing. When all the components are displaced relative to each other, creak arises, which is unlikely to please the neighbors. It is possible to prevent the appearance of unpleasant sound if you hardly fasten the lags to the floor.

In favor of the mount, there is another argument - fixation of the lag. In the matter of the degree of drying of a tree, buyers are forced to believe the seller's words, as it is impossible to find out this simple inspection.

Over time, poorly dried bars may be swollen, as a result, the coating will move, and the entire complex floor design will be overwhelmed.

Those who are saving to perform the fastening of the lags to the concrete base can be organized by a floating floor. In this case, the flooring is not attached to the supporting structures. It will provide excellent sound insulation, but it is necessary to use well-dried lags.

They do not sink through time.

The bars are bonded with each other in such a way that the lattice turned out. This design will make a floating floor more stable. In the interval between the bars, the insulation is stacked, the draft floor is constructed from above.

As a result, the whole design under its weight is pressed against the floor. Over time, such a floor will not change its form and will serve for a long time.

In most cases, the installation of the lag on the concrete base is made with their fixing to the floor, since the arguments in favor of this much more than likely minuses.

Technology laying Lag.

We gradually look at how to install lags on the concrete floor:

1. Quality materials are the key to successful repair..

   You can use the timber bar of coniferous rocks. Her humidity should not exceed 18%. Acquired bars must be acclimatized for several days in the room where the floor is planned. Lags that will begin to bent, should be postponed and not used in the floor.

   Wooden components of the future design should be treated with an antipiren and an antiseptic tool that will prevent the appearance of mold and insects.

2. The foundation is prepared, That is, the surface is cleaned from the garbage, all cracks are rubbed, protrusions are knocked down.
3. Tree should be protected from moisturethat is, it is necessary to perform waterproofing.

   For this, materials are used in the form of rolls, hydrophobic mastic, impregnating compositions, dense film.

4. You should prepare the necessary tools, fasteners and substrates for raising lag. Substrates must be rigid, which will not cover with time so that the emptiness is not formed at the support points. You can take thin planks, pieces of plywood or purchase special plastic substrates.
5. Lags should lay across the sun's rays falling out of the window.

   Wood during temperature drops can be deformed, and when laying in this way, all lags will warmly warmly. In the premises of such halls, lagows need to lay across movement. This will give the floor of greater strength.

6. Depending on the thickness of the roughing, the distance between the bars is selected.

   The more thickness and higher strength, the farther from each other lags are stacked. As a rule, the distance is approximately 40-50 cm.

   The nearest lagows should be located from it in 2-3 cm, while others - depending on the size of the room.

7. After complete assembly of the crate, it should be outputting it in a horizontal plane. It is best to have a smooth base. There are masters who even make a thin cement screed for this, provided that the flooring drop is allowed.

   You can not perform a screed, as the use of lag allows you to align even a very uneven floor. If the bar is below the required level, the substrates are put under it.

8. To provide depreciation and additional waterproofing wood Lags are needed to lay on linoleum, rubberoid, polyethylene or something else.

   It is important that the material used is not mild. Otherwise, after some time, he will see the pressure on him, as a result, the gap is formed, which will eventually lead to the appearance of unpleasant sounds, such as creak.

After completing the construction of the design of the lag, it remains only to fix them to the floor.

There are the following ways to attach lags to the concrete floor:

• with the help of dowels and screws;
• attaching anchors;
• the use of galvanized corners and screws.

The choice of the attachment method depends on financial capabilities and personal preferences.

Fastening Lag Samorzami

Such a fastener for lag, as the self-tapping screw is the easiest and most inexpensive option, but the guaranteeing excellent result.

In the lags and the foundation it is necessary to drill symmetric holes. Then the dowels are inserted into them and the screws are screwed.

The distance between the holes may vary within 40-80 cm, depending on the case.

The length of the self-press should be equal to the thickness of the bar plus 5-6 cm.

You can use self-drawing with a carving that is not up to the hats. They allow better pressing lags to the floor.

Use anchors

To obtain a reliable and long-term attachment, you can take an anchor for the floor lag. In addition to holding a bar in one place, they also attract it to the surface, giving the entire system additional rigidity.

In essence, the anchor is a dowel, but much more powerful.

Its dignity is high resistance when pulling out, so it is used when installing very heavy structures that create a large load on fasteners. The probability of full breaking of the floor on the lags from a concrete base is approaching zero, so you can make the mount and self-draws. However, anchor is often used for these purposes.

So, how to fix the lags to the concrete floor with the help of anchors? This method is performed similarly to the attachment of self-draws.

In the bars and concrete floor the same holes are made. So that the bolt's hat is sticking out, it must be hidden, without damaging the wood, for this, the lags should be pre-translated.

Usually, it takes 3-4 anchors to fix one lags within the room.

Anchor shut-off element should be inserted into the hole in the floor, then you need to screw the bolt into it through the bar.

Anchor bolts are made of different lengths: 45-200 mm. When the length is selected, the lag thickness plus 6 cm for the rehabilion into the base should be taken into account. It is recommended to acquire anchors with a diameter of 10 mm.

Fastening Lag Corners

Another fastener is used for the floor lag - galvanized metal corner.

One side of the corner is attached with the help of self-tapping screws to Brus. The self-tapping screw should enter a tree by 3-4 cm and best at an angle, it will increase the strength of the connection.

The other side of the corner should be restarted.

It should be fixed in the above methods, that is, with the help of a dowel with self-drawing or anchors. Instead of corners, you can take the profile of the P-shaped form.

Adjustable floors: analysis of the technology of the device lag on the supports do it yourself

Fastening adjustable Lag.

Installation of an adjustable system is easier and it will be easier to get a perfectly smooth surface. In this design, instead of anchors, plastic racks are used, which are screwed into wood and fixed to the base by means of a dowel (more details: "How to make adjustable floors on the lags with your own hands"). Rotating special bolts can be set up the height. After the laugs are adjusted, the protruding part of the bolts must be cut off.

Conclusion

In a wooden house, it is not recommended to fix lags to the floor. And if a concrete screed is used in the room as a base, then in this case, it is necessary to mount the lags to the concrete floor or not. In such a situation, the fastening will not be superfluous. It is all right enough, the main thing is to use high-quality materials and strictly follow all the rules.

Then the design will be reliable and will serve for a long time.

Adjustable floor on meroallically anchors

Adjustable floor on polymer bolts

In the late 90s, Russian construction appeared technology of adjustable floors. This completely new form of foundations composed competition with concrete screeds, before that widely used in residential buildings, apartments, any buildings.
Adjustable floors Have such an advantage in front of concrete as simple and quick installation. They are used under the purple floor of the parquet, laminate or parquet board in modern buildings. As a result of official tests, it was possible to prove the durability of such floors. The term of their service reaches 50 years under the condition of proper use.
This field equalization technology has significant advantages over other ways to prepare:
lack of dirt and water;
the ability to regulate the floor within 6 -15 cm and above;
efficiency and manufacturability of the laying process, relative cheapness;
High speed mounting - 100 m2 for 2 days;
accuracy of alignment;
The relative ease of structures compared to concrete, dry ties, and, therefore, smaller overlap loads.
There are two types of structures of adjustable floors, depending on the height of its lifting. If you want to arrange a floor with a height of 4 to 7 cm, the floor design will be applied, adjustable plywood On the stove. Most often, adjustable plywood is used in new buildings. If the floor is needed higher or slightly significant, then the structure is used adjustable lagham floors . It is used for floors over the floor beams. Most often to regulate the lags are resorted to replace old floors with their dismantling.
Adjustable floors help to eliminate significant differences in height during the dismantling of the old floor, when to the required level is high. For example, during finishing works, an old floor covering was removed, and the height between the required level and the resulting base does not allow to resort to other leveling technologies.
The design of the adjustable floor by lags is used for:
Floor devices in new buildings;
restoration of pilaf in old rooms;
raising the floor to reduce the load on the overlap;
Multi-level flooring;
Hide under the gender of electrical engineering and engineering networks.

Adjustable plywood ( ).

Flooring device with adjustable plywood.

Unwillingness to lift the floor highly or the absence of such a possibility can lead the owner of houses or apartments to the use of the new technology of the flooring device - adjustable plywood.New buildings or low ceilings require a special approach. In such cases, it is inconvenient to apply lags, and instead, take anchor stiletto with thread, install, fasten them at the base of the ceiling slab. Plywood sheets are put on the studs with pre-drilled holes. For floors, special moisture-resistant plywood sheets with a thickness of 10 mm and 1.5 m with dimensions are 1.5 m. As a result, we get a fane on the legs, because the sheets stand on the anchor studs. These legs (studs) are attached to the concrete floor. To adjust the height of the sheets on the studs, screws with a washer, unscrewing or twisting which leads to lowering or raising plywood at the desired height until it turns out the flat surface of the floor. In conclusion, on top of the aligned layer of plywood, the second sheet is stacked and attached to the self-tapping screw. After that, you can proceed to the installation of the floor covering. Such a base of plywood does not rise more than 7 cm on the basis of the base of the floor.

The cost of the device adjustable It consists of the size of the room and additional work.
