When building a house or cottage there is a need to arrange a staircase. Stair structures made on the basis of a metal frame are the strongest and durable.

Moreover, the use of metal allows you to solve the most intricate design projects - from the profile pipe you can create unique and non-standard compositions that are suitable for the interior.

Types of stairs

The separation of stairs to species occurs in several positions: material manufacturing, design, purpose, location (internal, exterior).

As a material for making staircase structures Metal, wood and reinforced concrete mixtures are used. Most often these materials are combined.

The designs are:

• power plants are the easiest and most common design. It is two parallel supports, to which steps at an angle of 900. can be both stationary and portable, for example, a stepladder;
• marsemen - have a more complex design, which implies the installation of steps on the beams installed at a certain angle. As reference elements, the guards or boosters can act. Such quite under the power to fulfill the owners of a private house with their own hands;
• screw - steps are mounted on one side to the supporting beam, and the pail is fencing the other side. Steps are made in the form of a triangle or sector. It is quite difficult to make such a design;

• bOLATE STADERS - In this case, the steps are fixed directly to the wall with special durable bolts (hospitals). The other side is connected by railings. Mandatory condition for this type of stairs is a strong wall capable of withstanding the load.

Advantages and disadvantages of stairs from the profile pipe

The staircase from the profile pipe do it yourself has a lot of advantages in comparison with structures From other materials:

• high strength, which is provided by the profile pipe;
• long service life, you can even say that this is a staircase for centuries;
• the process of making the framework has been worked out before the smallest detail, so it does not take much time;
• the use of different fasteners, you can implement any structural designs;
• relatively cheap building materials on the frame.

Along with the advantages, there are some "minuses" of stairs from the profile pipe, which must be taken into account before the start of work.

So, a metal frame is a sufficiently heavy design, so it is necessary to use smaller materials such as plastic or glass for auxiliary elements.

But this nuance Allows you to give them a more aesthetic appearance. The second point: The use of a metal profile implies that all connections must be welded, therefore, to be able to be able to use the welding machine.

Stages of manufacturing stairs from profile pipes

The most commonly used variant of the manufacture of the staircase is a frame of a profile pipe, and the steps are made of wood. For the base, they take a pipe with a diameter of about 60 cm and a corner of 40x40 cm.

On the example of this design, consider the main stages of the work:

1. At the first stage, the calculation and drawing of the future design make, determine the number of steps and calculate the length of the rower. The most optimal dimensions: the width of the stairs in the range of 80-120 cm, the height of the steps is not higher than 20 cm and at least 12 cm, the depth is 30 cm.
2. Next, perform the marking of the pipes and their cutting, make the framework under the step.
3. It is necessary to conclude a platform that will serve as the basis of the whole design, as well as to keep the angle of inclination. This level is considered to be zero - it will be the first step.
4. Mounting the profile pipe, fixing it with welding to bookmarks in a concrete platform on one side, and on the other to the anchors that are mounted in the wall.
5. Corners are welded to the metal pipe, the calculation of the dimensions of which are determined at the initial stage. It should be noted that all sizes, even if household steps are manufactured, it is necessary to observe exactly.
6. When the frame is assembled, the railing is welded to it (if they are metallic) or fasten in a different way if a tree or other material is used.

How to make a staircase from the profile pipe with your own hands? (video)

Construction features

In the process of making a staircase from the profile pipe, there are nuances, the knowledge of which greatly simplifies the performance of work. So, if the railing is installed on the side of the staircase, then it is possible to increase the width of the span.

When erecting the stairs, it should be borne in mind that during operation, the current construction of the design may be needed. For this purpose, there is a gap between the wall and the supporting structure.

So that there were no vibrations of the staircase when moving along it, the length of the racks in the spans is limited.

A fully metallic staircase from the profile pipe is not very attractive, so often use auxiliary materials, such as glass, durable plastic or grinding wood. This not only facilitates the design, but also makes the appearance of the stairs more beautiful.

Power stewing

In the subsidiary farming, the Pilot Stepberry is an indispensable thing that it is useful for performing any high-altitude work. You can make it with your own hands. There are a stepladers of one-sided or bilateral types. The structural stewdrill looks as follows - two parallel, and the steps attached to them.

The calculation of the height of the stepladder is made in the process of determining the interval between the base, that is, by the floor, and the last step. The optimal interval between them is 20-25 cm.

According to functional features, there are a lard of three types: a classic, universal or transformer.

The framework of universal stepladders can be folded or telescopic, in which the sections are put forward gradually, as needed. Fix sections by snap or hooks.

The folding stepladder works in several positions, and besides compact and easy in the assembled state, which significantly simplifies transportation.

In unscepted steps compounds are performed using welding, And the constructions transformers are joined with bolts. This connection method allows you to quickly dismantle the damaged item and replace it.

Made with her own hands, has a number of advantages, like ease, practicality and ease of use, and a high degree of reliability.

When designing any metal structures, a question arises - which metal rolling, and what section should be used to ensure the reliability of the design by the impact of the alleged loads. It can also find the methods of accurate calculations or use the software resources to calculate almost any designs. However, it is almost always for only professionals who know how to use software tools that know the production technology of metal structures and having the ideas about metal rolling.

Very often, when designing small and non-complex objects, for example, stairs to the second floor, it is necessary to choose metal-rolls as they say "on the eye". To somehow justify your choice, but attend confidence and in yourself, and in the customer, we offer the option of the simplest ("for beginners"), calculation.

Suppose we need to build a metal frame of the stairs to the second floor.

Let it be: the length of the staircase 3m. , inclination angle 30 0, alleged load: 200kg. - weight of construction and 500kg. - Additional load. It is necessary to select a profile pipe for the carrier beam (theetics)

Calculation is carried out with a certain degree of approximation. Figure 1 shows the ladder beam scheme,

Fig.1Ge:

L - length of beams

q - the angle of inclination of the stairs

In our case: F \u003d 500kg.

L \u003d 300cm.

q \u003d 30 0

P \u003d 200kg.

For simplicity of calculation and, given that, as a result, the staircase on the second floorlessness is sufficiently rigid, allowing to distribute the load exhibiting the circuit (Fig. 1) to be given to a diagram with a uniformly distributed load,

Fig.2Ge: B - horizontal component beams,

For our case: B \u003d L * COS Q \u003d 300 * COS 30 0 \u003d 260cm.

Q \u003d f + p \u003d 500kg. + 200kg. \u003d 700kg.

G \u003d. Q / b. \u003d 700kg / 260cm. \u003d 2.7kg / cm.

Under the influence of loads, the pipe will begin to be fed. If minor deflections after eliminating the load, the pipe will return to its original state. If the load exceeds the permissible, deformation (not corrected deflection) can occur. In order not to be deformed, a bending moment is necessary (arising from the load) to compensate for the moment of resistance of the pipe. In our case, the bending moment formula:

M \u003d. q * b 2/8 substituting the data we get: m \u003d 22815kg.cm.

The moment of pipe resistance depends on the pipe material (stairs beams) is considered by the formula:

W \u003d M / R, where: R is the calculated metal resistance

pipes, for steel st.3 - R \u003d 2100.

Substituting meanings M. and R. we get that W. \u003d 10.86cm3

The moments of profile pipes are calculated and are reduced to the tables that can be found in the corresponding topics of the Internet. We need to take the tables in the tables that W. more obtained in our calculations (\u003e 10.86). Resistance Moment is greater than 10.86U of pipes 70x70, 80x80, etc. If you take the pipe 50x100, then on the side 100w \u003d 24cm3, i.e. Almost two and a half times more than in our calculation. In fact, for the beam (theetims) of our ladder on the second floor, the profile pipe 50x100 is quite suitable for the carrier elements of stairs, you should take with a three-five-time reserve from possible loads. Additionally, it is necessary to check the brain of beams (the tents, the Kouryra stairs). In the case of a uniformly distributed load, the deflection is determined by the formula:

f \u003d 5. GB 4/384 EI where: f. - Maximum deflection

G. - Uniformly distributed load

b. - horizontal projection beam

E. - Module of elasticity (tabular data)

I. - Moment of inertia (tabular data).

For our case G. \u003d 2.7 kg / cm. b. \u003d 260cm., E. (for steel st.3) \u003d 20.4 * 10 5 kg. cm 2 (reference data), I. (for pipe 50x100) \u003d 137cm. 4 (tabular data). Eventually:

f. \u003d 0.6 cm.

The deflection is insignificant, the noma at the beginning has simplified the task and led it to an option of a uniformly distributed load.Realo the load told focusing and deflection can be three more. On the other hand, we will calculate the same beam (theater, Kosur). If you take a classic option with two, for example, Kosomers, then the deflection will again decrease. In general, if the deflection should not be allowed, then the backups should be made, connect several pipes or search others Options.

In conclusion, it is necessary to emphasize that we did not try to make accurate calculations, and they tried to prove the 40x80 or 50x100 stairs to the construction of the pipes 40x80 or 50x100.

Metal - reliable and durable material, which serves decades. Possessing welding skills, from metal parts you can make a lot of useful things for a household or garden plot: wall and floor hangers, elegant miniature shelves, a coffee table for a gazebo, a multi-tiered stand for flowers. The top of mastery is a useful and impressive product - a staircase from the profile pipe with his own hands. Consider three options that are suitable for self-making.

Staircase without a railing from a metal profile and wood

Advantages of a metal profile

During the country's work or construction, it is often used by wood: boards, logs, bars, lining, Faneru - forgetting practical metal blanks. Under the influence of external factors (damp, wind, temperature drops), the lightweight in the processing, but having a weak structure of wooden products crack, lose weight, lose attractiveness, while properly treated metal retains its operational properties for years.

Profile metal pipes - factory products, characterized by the form, length and parameters of the cross section

For the construction of light products, a metal corner is suitable, but it is inferior to the strength profile. Under the influence of gravity, the design from a corner or channel is deformed, why its functionality comes into disrepair. Large load is able to withstand more reliable products, so experts recommend to weld the staircase from the profile pipe.

Here are some properties characterizing a metal profile as an ideal material for the construction of a staircase:

• allows you to create screw, marching or autonomous type of structures, straight and turning;
• it can be used both in combined structures (with wood, plastic, glass) and alone;
• has ample painting opportunities - there are dozens of solutions to decorate the metal surface with special colors of traditional colors and shades "Metallic";
• the shape and dimensions of the profile are ideal for the assembly, which allows for welding design to spend a minimum of time;
• the service life of the finished design is calculated by decades (much depends on the quality of welding).

Performing a calculation for the assembly of a staircase from the profile pipe, you will understand that the cost of the construction is small compared to, suppose with analogue of natural stone or expensive wood.

Self-assembly options stairs

The simplest way to check the quality of welding and consolidate the skill with the welding machine - make a small device for 7-10 steps, with which you can climb the roof of the barn, shoot apples from trees or painting the walls at home.

Video: A staircase from the profile pipe

Domestic ladder

There are several ways to assemble with their own hands of the peeper staircase from the profile pipe. If you are not familiar with the subtleties of the work with the welding machine, the steps can be fixed using bolts and corners, but the welded structure is stronger.

Instead of the inlet ladder, you can make a stepladder - a construction, convenient for construction work

So, we will need:

• profile pipes 200-250 cm long with a cross section of 40 mm - 3 pcs.;
• steel plates of the same section - 4 pcs.;
• metal corners - 12-16 pcs.;
• crafting table;
• household welding machine;
• set of 3-millimeter diodes;
• bulgarian with metal discs;
• sandpaper (grinding);
• LKM for metal (paint, anti-corrosion primer).

Metal staircase design welded from profile and corners

Before you cook the staircase from the profile pipe, one workpiece must be cut into several parts of 30 cm - the steps will turn out. Their number depends on the length of the profile: for example, 6 small segments will be obtained from the two-meter blank.

This looks like a metal frame with marking and a set of crossbars for anxular staircase.

Progress:

• we make markup - on long crossbars we indicate the place of welding, the intervals between the marks - 25-30 cm;
• if it requires corners for additional fixation - we weld them first;
• in order for the design of the stability, we weld the crossbar and extreme steps, thus we get a rectangular frame;
• weld the remaining short segments;
• the ends of the profile do the deaf - for this we use metal plates;
• we clean the irregularity of the seams;
• ground and cover special paint.

If you need a larger ladder, use another profile, for example, with a cross section of 50 mm. The harder and longer design, the powerful and thicker should be a pipe.

Screw staircase for the second floor

Screw type construction is used when there is a deficiency area or a need for an additional original design element. In the process of preparation, you need to purchase a tool: a welding machine with diodes, a circular saw, a hacksaw for metal, a file, a grinder, a hammer, a roulette and a marker. The easiest option is the staircase from the profile pipe in the form of a pillar to which steps are attached along the spirals.

The screw staircase on the second floor, assembled from a metal profile and wooden steps, not only is functional and convenient, but also serves as an ornament for a brick or wood house.

As a support, a thick-walled round of the circular section protrusion, the length of which depends on the distance from the floor of the first floor to the floor (or ceiling) of the second floor. From the second pipe, with thin walls, but a larger diameter, it is necessary to make a sleeve, the optimal length of which is 22-25 cm. The sleeves will be drawn to the support column one after the other already with the stewed steps. The attacks are of different shapes (rectangular, oval), but the most successful option is an elongated anoscele triangle, the vertex is welded to the sleeve.

Interesting designer solution - the removal of the screw staircase will outward and design the entrance to the second floor from the street

Progress:

• We weld the frames for steps to the sleeves.
• We ride the sleeve on the central support.
• We establish the support post on the concrete base, fix in the upper part.
• Give steps the desired position, weld the sleeves among themselves.
• To give strength, connect the steps with metal columns and from the outside.
• We clean, soil and paint the whole design entire design.
• Decorating the steps (boards, thick plywood, metal sheets).

In addition to the profile, it is often used for the device of screw structures - durable metal beams.

Single glands in the cellar

So that the homemade staircase from the profile pipe in the cellar was durable, stable and convenient, it is necessary to make faithful calculations. Usually follow the following parameters:

• width - 90-110 cm;
• comfortable angle of inclination - 45º;
• the distance between the steps is 15-20 cm;
• stage depth - 30-35 cm;
• height of the railing - 70-90 cm.

Profile parameters depend on the size of the stairs. Thick metal crossbars will be required, which will play the role of cosomers, and a smaller profile for welding frames of steps.

We collect the design in the following sequence:

• cut a profile for kosomers and steps to separate fragments;
• we establish a platoon on the place intended for them: the upper part is secure bolts to the site or special crossbar, the lower concrete;
• if spans are needed - set the lattices (from a metal profile or thick reinforcement);
• billets for steps weld to Kosomers, withstanding the same interval, follow the parallel location of metal parts;
• we clean the seams, soil and paints;
• metal or wooden sheets for steps screw bolts.

Profile stairs will serve long enough if you make accurate calculations. After installing the main parts - frame and steps - do not forget to improve the construction with decorative parts or decorations for the railil.

Stairs have a solid construction. Aluminum staircase is useful in the country or at home. Many people use the insertion stairs during repair and finishing works. With such a subject, you can easily paint the ceiling, hang clock, shove wallpaper, wash the windows or install the lighting device on the wall. They may consist of one or more sections. Convenient design allows the use of stairs not only for domestic purposes, but also in professional construction.

Power staircase is a portable and universal subject. It has low weight. It can easily be put in the right place to perform a number of specific actions.

Stairs made of metal frame, have high strength. The frame is strong and reliable. Metal - the longest material that has a long service life. Therefore, the staircase will last you for a long time.

Metal stairs can have a different design, so this attribute will fit into any interior.

Make the frame of the filter stairs from.

Metal frame has many advantages:

• High strength;
• Long service life;
• It is quickly made;
• Can be any in design;
• For the manufacture uses inexpensive material.

The main purpose of the aluminum gear staircase is the ability to rise to the necessary height.

But it is difficult for it to rise or the descent of goods, so it does not fit for such purposes. To lift the goods is easier.

Pottal staircase from the profile pipe with their own hands

You can buy a staircase in a specialized store, or make it yourself. Make it is possible from the profile pipe. This material is affordable and sold in building stores. Aluminum tube has excellent qualities and is used to make such products.

Power staircase has a simple design, so make it easy and quickly independently. The design of the staircase has a tutor and steps, which should be located at the same distance relative to each other. It rests on the walls and floor.

The angle of inclination should be 65-70 degrees relative to the wall. Then she will stand reliably, and this will provide you with safety when it is used.

The optimal distance between the steps should be 0.35 m. The staircase should not slide along the floor. On the legs of the stairs wear rubber tips or plastic. They are able to ensure the stillness of the inlet stairs.

For the manufacture of anxid aluminum staircase, you will need the following:

• Two profile pipes 2 m long;
• Long pipe with rectangular cross section;
• Nuts, washers, bolts (or welding machine with mask);
• Rubber or plastic tips.

Profile pipes for the taiga can be of any section. For steps it is worth choosing an aluminum pipe with a rectangular cross section of 1.65 m.

The rectangular section of the profile will allow safely climbing and descending along the steps of the inlet stairs.

The optimal length of metal profiles is two meters. This length is enough for the manufacture of anxal staircase.

If you have a welding machine, then you will not use additional fasteners - nuts and bolts.

For the manufacture of stairs use drawings. They indicate all the dimensions of the design and place of fixings.

If you are not sure about your abilities, then the staircase is better to buy in the store, and when the model is selected, some design features are considered:

Power staircase with your own metal hands

The withdrawal ladder from the metal is easy to follow the instructions for the manufacture. If you have a welding machine and a mask, then the process will take a small amount of time. Using this device, you can fix the steps to the tutor reliably.

Step-by-step instructions for the manufacture of anxulated staircase:

• Cutting the profile tube on equal parts for steps;
• We drill the bolt holes in these pipes;
• We make markup on two long pipes;
• Fix the steps to two side profiles with bolts;
• We put on the legs of the stairs tips.

If there is a welding machine, then you do not need to make holes for fasteners.

First step: You need to cut a profile (with a rectangular cross section) with a length of 1.65 m per five equal parts of 0.33 m.

Second step: Gently drill holes at the same distance for fastening elements.

Third step: Apply marking for steps on two meters long profiles. The distance between them should be 0.35 m.

Fourth Step: Screw bolts, fix with nuts. Stairs of the stairs should be in a fixed state so that the design of the staircase does not break over time.

Fifth step: Do not forget to put on the lugs on the legs of the stairs, so as not to fall from it during operation.

How to make aluminum filter stairs do it yourself

Power staircase - the right thing. If you have a little height, this thing will come in handy to you. It can be made independently, possessing all the necessary materials and tools. Make a reliable staircase easily and quickly using a welding machine. You can paint it if necessary in the desired color and put in the room, and not in the masonry. Thus, you will make it part of the interior, and it will always be at your hand. It is convenient and practical.

Types of aluminum appartible stairs (photo examples)

It is almost impossible to imagine a house without a staircase. Even if the structure has only one floor at its disposal, the stairs are mounted on the porch or lift to the attic and attic.

Materials for creating similar designs are very much, but today there has been a particular importance for the consumer an option made from a metal pipe of the rectangular section. There are many reasons for this, but the main is ease of construction and excellent performance.

Today we will analyze how the staircase from the profile pipe is done with their own hands: video and detailed instructions will be attached.

Any serious work begins with the fact that you need to make a project of the built structure, well, or at least make sketches in the form of a sketch. The calculation of the stair structures does not relate to the category of higher mathematics, but still it is worth considering carefully, so as not to get in the end of non-slippery during the assembly of the stairs.

Calculation of the marching staircase

So, let's first describe how calculations are performed under the marching metal stairs from the profile pipe.

The marching staircase is a construction collected from one or more areas with a straight lift. Depending on the number of marches, single-hour and multi-hour versions are distinguished. The choice of entirely depends on the location of the stairs and the desired height of the lift.

• In the multi-party structures of the marches are connected using sites or running steps

• Such ladders can unfold 90 degrees - they are put when places under a long march is enough. The playground most often is closer to the floor level of the first floor, in the corner of the room

• 180 degrees - such a design allows two march of smaller sizes to fit. The rise of such a staircase is gentle, and convenient for movement. Continuing the design, you can make a rise to any number of floors.

• By 270 degrees - in this case, the staircase has three march, each of which turns relative to the neighboring 90 degrees. The design is very compact, which allows you to install it in narrow places, for example, a small erker or corridor.

Knowing the types of structures, you can proceed to calculations.

You need to act in the following sequence:

• We define the place where we want to install the staircase.
• Assessing the size of the room and the height of the overlaps of the second floor, you can decide on the number of marches. Remember that at this stage, all the conclusions are cape. We can see everything in more detail when calculating.
• Measure the height of the lift, given the thickness of the inter-storey overlap.

Tip! Do not neglect millimeters in order not to be mistaken in the calculations. Make everything as much as possible immediately.

• In order for the stairs to be conveniently moving around and adults and children, it is necessary to optimally choose the ratio of the length and height of the stage. These parameters are called still scenario (sides of the rest of the foot when climbing) and the riser (vertical decorative bar). The optimal dimensions fit in the following ranges: Length 25 - 33 centimeters, height 15 - 22 centimeters.
• As for the relationship, it should be placed in formula 2x + y \u003d 60 (64) or x + y \u003d 47. All values \u200b\u200bare specified in centimeters and fitted under the width of the middle-height person (175 - 180 centimeters).
• The number of steps is calculated very simply - a fairly height of the opening is divided into the height of the riser. Having received this value, you can calculate the march length - you need to multiply it to the length of the sticky.
• These values \u200b\u200bare directly related to the angle of inclination of the stairs. As you understood, we got an imaginary triangle, which was carried out on the scale of paper, you can accurately measure the angle of inclination.

Tip! It is most convenient to perform drawings and calculations on a high-end sheet from school notebook in mathematics.

• But to calculate, we lack another value - the length of the march itself. To calculate it can any student of a sixth grade, familiar with the Pythagora theorem. Well, we remember: a² + c² \u003d c² (the square of the hypotenuse is equal to the sum of the squares of the cathets). Suppose, the height of our imaginary overlap is 260 cm, and the length of the staircase is 400 cm. We carry out the calculation: (260 * 260) + (400 * 400) \u003d 227600. Remove the root and get 477 cm with the "tail" - this is a march length.
• We look, whether to fit such a staircase in the outlined place if not, you can try to change the settings of the sticky and the riser, or if the angle of inclination suits you, then save it by breaking up a few marches.
• In general, the angle of tilt for the home staircase is very important, as it will take place and small children and older people. The more often the rise will be, the easier it will overcome it. According to regulatory acts, the values \u200b\u200bof this parameter must be from 23 to 45 degrees.

• But it is best when the value does not exceed 33 degrees, as the coolest stairs are less comfortable. Less values \u200b\u200bare suitable more for ramps than for stairs.

Tip! By making calculations, you can hardly be able to adjust the parameters for integers - there will always be a small residue. Round the result in the big face. All deviations from the specified parameters can be eliminated due to the lower frieze stage.

Calculation of the screw staircase

The spiral staircase is very beautiful and selected by designers for this reason, besides, it takes much less space than the route design. But it is abuse of minuses: such a staircase is considered the most dangerous when lifting; It is difficult for it or at all it is impossible to raise large loads; The price called the masters for the assembly is exhausted.

But if you have nowhere to go, and you need to install this option, do not be discouraged! We will tell in detail how to make such a metal frame for the staircase from the profile pipe, as well as how to properly separate it.

Saving "on the face." The only thing that is required of you is the ability to work with a welding machine and a challenge, which will move overall blanks.

Calculation of the screw design may seem to someone too complicated, but we assure you that following us, you will not be able to make a mistake, as you need to use only a few formulas. In extreme cases, you can always use special calculators that can be easily found on the Internet.

So, remember the designations of the ladder parameters:

• N. - The height of the span. As in the case of the marching staircase, takes into account the thickness of the overlap.
• H1 - Distance between the turns of the stairs. That is, the distance from one stage to another, which is exactly over it. The minimum comfortable value that should be observed is 2 meters. So, even a high person will not hit his head when lifting.
• h. - Height of the stage. The risers on the screw stairs are made rarely, but the parameter remains unchanged, as for the march stairs. For convenient lifting, this value is reduced to 12 - 22 centimeters.
• h1. - Stage depth. An ambiguous value, since the steps of the screw stairs are of the trapezoid form. GOST and SNIs set the size of a smaller face of 10 cm, and the biggest side, in principle, is not limited (depends on the width of the lift), but the recommended value is about 40 centimeters.
• Working depth of steps - This is the conditional line on which the lift of the person will be carried out. Its parameters must be calculated so that the value is laid in the normalized 25 - 33 centimeters.
• L. - The length of the stairs at a given radius.
• R. - external radius. This value should not be less than 80 centimeters. When placing the stairs in the Erker rounder - it is advisable to increase it to the inner radius of the room to be able to rest the free edges of the steps on the walls.
• r1 - The working radius, the same line that the person moves when the lift is moving.
• r. - The radius of the central support. It will take for calculations when the design will not be an internal column, and the staircase will rely on the boosters or adjacent walls. The fulfillment of such stairs will be an impracticable task for beginners, so we will not paint them.

As with the last case, we begin with a span height measurement. Suppose that we have it is 3 meters. Then we determine the external radius of the design, focusing on the size of the room in which the installation will be performed. For convenience, we take 1 meter.

Next, determine the entry and output points. Suppose they have each other in our other, that is, the angle of rotation at lifting will be exactly 360 degrees. This data will be enough to calculate the external lifting length.

• As we remember from the school year of geometry, the circumference length is calculated according to the following formula: L \u003d 2πr - where L is the length, R radius, and π is a constant that is approximately equal to 3.14.
• We believe: 2 * 3,14 * 100 (cm) \u003d 628, that is, 6m 28 centimeters.
• Now you need to know the number of steps, but for this you will first need to determine the lap of the march. It is believed that a person is lifted by a radius, which is 2/3 from the external one. Based on this, the answer can be obtained in three ways.

1. First, 628 * 2/3 \u003d 419, with rounding to the biggest;
2. Second, according to the formula Lrarab \u003d 4 / 3πr \u003d 4/3 * 3,14 * 100 \u003d 419, as well with rounding;
3. The third, calculate first the working radius and perform the calculation by the formula for finding the length of the circle: 2/3 * 100 * 3,14 * 2 \u003d 419 - 4m 19 centimeters.

• Now, knowing the working length, we can choose the optimal sticky width. Suppose we want 30 centimeters. We divide the working length of this number: 419/30 \u003d 14 with rounding. This is the number of steps in the span
• It remains to check the height of the sticky. For this, the height of the span is divided by the number of steps: 300/14 \u003d 21.42. The value is slightly twisted, so let's try to reduce the width of the sticking up to 25 centimeters: 419/20 \u003d 17; 300/17 \u003d 17.6 cm. Now the rise will be smooth and comfortable.
• Oh yes! Almost forgotten! Fully determine the geometry of the stage, calculating its external length: 628/17 \u003d 36.9. Little! Then we return to the selection of parameters until we find the optimal value.

But this is not the end, it remains to determine the size of the output platform, with a loan to the value of H1. As lifting, each stage will take away from the total height of the span value of the tossy height. Due to the fact that H1 is limited to the limit of two meters, the site width should not be more than 4-5 coming - do not forget about the thickness of the overlap.

The process of assembling the frame of the staircase of the profiled pipe

After all the drawings are willing, you can start making a staircase. Exact compliance with all the size obtained during calculations does not allow you to make a mistake during the markup of the blanks, so be careful.

Tools and materials

To fulfill all the works, we need the following tools:

Also let's list and the basic materials we will work with:

For fastening steps to frame, bolts or screws with washers are used. The bolted connection is through, and the mounting on the self-tapping screw can be made in an imperceptible, drove them into the level of the bottom.

Assembling marching design

Two main types of design are common, although they are far from the only one. The first is with an inclined beam and the woven holders under the step, and the second - with the broken Kosourg from the pipe. Let's look at both options.

The first option is made much easier and faster, but in the end it will be a bit more expensive, and the appearance of the structure looks very simple and unpretentious. It is better to use this method when the staircase frame is completely hiding after the trim, or to build a design on one support with the players, as shown in the photo above.

• The increase in the cost of construction is due to the fact that the pipe is used as a pipe profile for the staircase with a cross section of 100x100 or even 150x150. In addition, it is necessary to weld the sheet metal plates with a thickness of 3 mm, which will also be more expensive than profiled pipes.
• When assembling, inclined supports are established first. If 2 march is provided in the design, then the intermediate platform frame is mounted, which will be the support for the beams.
• You can start the platforms in two ways. The first is that after determining the angle of inclination, the metal sheet is welded horizontally to the beam. So that he withstand the weight of a moving person, the vertical backup of the reinforath or a piece of pipe is welded in front of it.
• In the second method, the triangles from the pipes are first turned on the beam, which are connected at a direct or acute angle, in case you want the risers to go inside, in order to increase the area of \u200b\u200bsticking.
• On top of these reference elements the site is already breeding, although you can do without it. The edges of the sticking between parallel corners can be connected by crossings from the pipes or, at all, immediately turn on them with wooden steps, a thickness of at least 4 cm.

Tip! Additionally, it is worth noting that the weight of the design of this type is quite large and the lateral tipping of the stairs is possible. To avoid it, we weld on the racks of the supporting areas of metal with a thickness of 5 mm - so we will evenly distribute the weight of the whole structure.

How to cook the staircase from the profile pipe, the video in this article will show clearly.

The second version of the design looks more beautiful, but with its assembly will have to be tinted longer. The optimal cross section of the pipe under it is considered to be 40x60 mm, it is possible and more, but consider that the mass of the ladder will increase, which is not always justified.

There is also two ways to connect details, for the manufacture of a ready-made Kooker:

1. In the first way The pipe is cut into separate parts corresponding to the length of commencement and risers. Their edges are trimmed at an angle of 45 degrees (for a more accurate cut, it is better to get an end saw) and welded with each other, forming a ladder. In theory, everything is simple, but in fact you will have to perform many welding works, and constantly monitor the accuracy of the location of the parts. To simplify the task, cut the stencil from plywood, inside which lay the blanks.
2. The second way is much easier - We take a one-piece pipe and placing it in such a way that the point of the angular cut is the top of the equilateral triangle. The second triangle will be deployed relative to the first 180 degrees, that is, its vertex will be on the opposite face. We draw triangles on both sides, and then cut them out of the pipe so that the line to which the peaks are suitable, remained in place. Next, we will need to bend in this place the pipe and cook the connection.

Instead of the site to the boosters, also weld the crossbar.

Production of a screw staircase

Installation of the screw staircase begins with the installation of the central pillar of the support. Its diameter should not be less than 10 centimeters so that we can comply with the size of the adjacent edge. Savings when buying this item is inappropriate, since the axis of the screw staircase is experiencing serious loads.

Laying the lower edge of the post should be a strong reliable base - best in concrete overlap. The reference site is also required to distribute the weight of the stairs.

Tip! If you install the staircase at the same time with the construction of the house, so as not to buy an expensive sheet metal, the support can be built as a crosshair of segments of the same pipe, which is then lit into the concrete tie.

Supports under steps can be two types that depend on the section of the pipe used. According to the strength and external aesthetic component, they differ little.

1. If the pipes are purchased with a cross section of 20x20 or 30x30 centimeters, then it is better to cook a full frame around the perimeter of the sticky. For convenience - again we use a stencil. Calculate the angle of divergence of the faces is very simple. As you remember, 17 steps turned out in our theoretical calculations. We take an angle of rotation and divide it on this value: 360/17 \u003d 22 degrees. That's the whole settlement.
2. The second option is performed much faster. For him, you will need pipes with a cross section of 40x60. There are no lecturers here - we take a piece of pipe, 8 cm long, less than the length of the sticky, apply from the end of the second segment, which will correspond to the width of the stage, and weld them with the letter "T". In the middle, you can also add a transverse item as shown in the photo.

Finish finish

Here you actually collected the screw staircase with their own hands. It remains only to refine it. Due to the fact that the number of materials for this is very large, and the finish methods are even more, we will list only the main stages.

• First we grind the surface of the stairs, special attention, by paying welded seams. Ideally, they should not be forgiven and be smooth and smooth.
• Covered metal converter rust and wash it according to the instructions on the package.

• Breasting the surface of the metal.
• Perform painting of the whole structure.
• We are wearing steps and make a decorative trim around if it is planned.

Most often in private homes, a tree is used as steps under such frames. It is enough to install only a sticky, and the staircase will find an attractive look. "Stairs from the profile pipe" - the video that we picked up will show how this procedure is performed. Well, and we have everything! To new meetings!
