Features of the structure of spiral staircases

The spiral staircase consists of a rack, directly to which the steps are attached. The rack is spiral-shaped, treads are fixed on it. To ensure comfort when moving along a spiral staircase, as well as in accordance with GOST, the tread width is 20-40 cm. A staircase of this type is fixed on the ground floor to the floor and attached on the second floor to the end of the ceiling.

A distinctive feature of spiral staircases is that they do not need load-bearing wall... The structure can be installed anywhere, even in the middle of the room.

You can order a spiral metal staircase from us from the manufacturer of the following types:

• with a support in the center, which is a pillar, pillar or column, with attached steps in the form of wedges;
• on a bowstring, where the main element is a bowstring with steps;
• on the stringer, to which the steps are attached.

Metal spiral staircases are made from different types of metal. They are divided into 4 types:

• Cast stairs made of bronze, cast iron or brass.
• Welded stairs.
• Forged steel stairs.
• Prefabs that are assembled right on the spot.

Buy spiral metal staircasepossible with various step attachments.

• On sleeves, these are pipe sections with a diameter larger than that of the support. The steps are fixed on them at a certain height on the support pillar. The bolt is attached between the steps connected along the outer radius. On the outer string of the steps, they put racks under the railing. In this type of spiral staircase, the steps are attached to the bowstring.
• On the console - beams welded to the rack. The console acts as a step or base for it.
• On the supporting walls - if the structure is in the corner of the room, then the steps can be attached more securely. One side is fixed on the support pillar, and the other on the wall in special grooves.

How to buy a spiral metal staircase?

You can buy from us spiral staircase made of metal price Moscow | The prices for our spiral metal stairs are the most optimal due to our own production. We can guarantee the quality of the product and its reliability. To buy a spiral metal staircase to the second floor, you need to place an order in the feedback form on our website.

Such engineering solutions are not very popular in private buildings, as they are characterized by a number of disadvantages - the steepness of the rise, and this does not suit many; the complexity of installation; the inability to move anything overall from floor to floor. But the fact that spiral staircases are compact and can be installed anywhere, in a relatively small area, is an indisputable fact.

In addition, their final price is significantly less than models assembled according to other schemes, due to a decrease in material consumption. It is these arguments that in some cases are decisive when choosing a design. With how to make a spiral staircase out of metal with our own hands, we will figure it out in detail.

Preparation phase

The issue of assembling a spiral staircase from ready-made prefabricated elements (although this is also done by hand) does not make sense to consider. Each kit is accompanied by an instruction in which everything is described, point by point. But if you mount from scratch, then you first need to evaluate your own capabilities and decide on a number of points.

Methods for working with metal

The casting technique, as well as the assembly of the structure using bolted connections, is clearly not suitable. The first is due to the impossibility of implementation, and not only at home, but also in a small, albeit specialized, workshop. The second will not ensure the reliability of the spiral staircase, taking into account the constant dynamic loads that all its component parts will be subjected to every day. There remains only one acceptable option for performing all operations with your own hands -. If desired, practical skills can be acquired in a relatively short time.

Material selection

Taking into account the fact that the installation is done by hand, by welding, the best option is steel. It will provide the required structural reliability and, moreover, it is not difficult to process it at home. The processes of metal coating with polymer layers, nickel plating are described on our website in some detail.

There are recommendations on the use of aluminum for the manufacture of railings. Arguments - light weight and the ability to self-anodize structural parts (handrails, balusters, filling elements). The author will not argue with this, but draws attention to the fact that we are talking about a spiral staircase. Consequently, the requirements for the reliability of the fence (taking into account the steepness) increase sharply. That is why only steel must be used for such structures. And all other materials are just as additions serving as decorative elements, nothing more.

Choosing an engineering solution

Installation is carried out based on the features supporting structure spiral staircase.

• On bowstrings. The steps are fixed to the carrier beam with only one side.
• On kosoura. Both ends are open, and the step itself is located on the supporting element (beam) of the spiral staircase.
• On the bolts. There are 2 types of such spiral staircases.

Option 1 - the steps are fastened to each other with bolts; the central support is mounted.

Option 2 - the steps are attached to the wall of the house; there is no supporting beam.

• Lift Height (H) - Measured between the final floor levels of the lower and upper floors.
• The difference in height between the turns (H1) is the distance from the step to the one that is located strictly above it. In fact, this is a person's height with a certain margin. The recommended value is within 200.
• Riser height (h) - about 16 ± 4 for ease of movement. In some schemes, this structural element is absent, especially in residential buildings. This solution greatly facilitates the maintenance of the spiral staircase. In this case, it is necessary to eliminate the risk of foot slippage between the steps by reducing the difference in their height - no more than 16.
• The depth of the tread (h1) - so that the foot does not slide off the steps, is selected within 27 ± 2. But this is a general recommendation. It should be taken into account that, as a rule, when descending / ascending along a spiral structure, we move along a conventionally marked line, which is approximately ⅓ of the radius of the stairs from the outer end of the steps. When calculating its parameters, this nuance should be taken into account. That is, the indicated 27 cm refer to those points that are located on a conventionally outlined arc.

Basic requirements for spiral staircases

They are detailed in the corresponding GOST and SNiP. It makes no sense to list them all, since most of them are needed only by professional designers. In addition, each document contains a number of references to other regulations regarding, for example, characteristics of steels, requirements for welds, and the like. When making a spiral staircase with your own hands, given its small length, it is enough to know the basic provisions.

• Stair width. Installation of only one stringer is allowed if this parameter does not exceed 1.5 m.With a larger design, you will have to install an additional support.
• Step width. In order to ensure the safety of movement, a minimum has been determined - it is 0.9 m.
• h1 - the recommended depth is indicated above. But the minimum, at the point of abutment to the support - 100 mm.
• Opening dimensions. When calculating the parameters of a spiral staircase, it is necessary to take into account that the fingers of the hands should tightly cover the handrail. Therefore, it is necessary to leave a certain gap between it and the wall (about 8 - 10 cm).

The procedure for calculating the parameters of a spiral staircase

There are many sites on the Internet that have online calculators. But even if the calculations are done independently, the initial data does not change. What needs to be determined?

• Ladder overall height H.
• The optimal diameter of the structure, depending on the dimensions of the room and the style of its design. From this, the outer radius ® is calculated. For private houses, it is selected within (m) 1–1.5.
• The radius along which the conditional line of movement of the person passes ®.

Calculation algorithm

Before proceeding with the calculations, it is necessary to transfer all the quantities into a single system. As a rule, it is customary to make calculations in mm, but in fact - to whom it is more convenient. The main thing is not to substitute values \u200b\u200bin the formulas, for example, the height in m, and the radius in cm.

The length of the march is determined (L). In other words, it is the circumference (along the ascent line). We remember that it is at a third of the radius of the staircase from the wall. Therefore, r \u003d 2/3 R. How to calculate it correctly?

The diameter of the spiral staircase is (step width x 2) + section of the central support. Only after finding this value, you can begin to determine the "small" radius, the value of which is substituted into the formula known from school:

L \u003d 2π x r

The number of steps on the march is determined. Knowing the depth of the tread, it is not difficult to do this:

N \u003d L / h1

You can do it differently - divide H by h. The technique is selected based on a specific engineering solution. If the procedure for calculating the number of steps is clear, then everything else is not important.

One cannot overlook such a parameter as the thickness of the steps. The total is subtracted from the height of the stairs before calculating the number of stairs.

The diagrams and tables below will help the reader find answers to your questions.

What to consider:

• The above calculation method is used for spiral staircases of the simplest designs, when all steps are located on one turn. If there are several of them (which is rare, but found in private houses), then their number must be taken into account.
• The last step may be the same as the top floor, so it is not counted.
• If the result is a fractional value, then rounding is done up.
• The placement of steps with a slight "overlap" (in the projection) increases the comfort of movement.
• It is not recommended to use a workpiece with a cross section of less than 50 mm as a central post.
• The calculation of the load is made taking into account the simultaneous presence of at least 3 people on the spiral staircase.

It remains to add that in most cases it is advisable to install the load-bearing part of the structure at the initial stage, and install all other elements already in place.

Success to you in this business!

Spiral staircases (metal) are a type of steel structure, where the steps are arranged in a spiral manner in a circular area. At the moment, they are a very popular type of construction. The model combines elegance and compactness. Used in the construction of almost any building, be it a summer house, private house, a building with a second floor, or an entertainment center or office. They serve as an excellent alternative to wooden and other structures with wide flights of stairs. Wherever space-saving as well as spectacular decorative view, spiral structures are installed from a number of steps.

Benefits of steel screw structures

1. Elegant and original appearance. A simple room easily becomes modern and beautiful.
2. There is no need for a lot of space in the house.
3. The price for a metal spiral staircase is lower than for a marching staircase.
4. Installation of these structures is not difficult.
5. A large assortment.

Of course, like any other thing, steel structures have disadvantages. The main ones are:

• inconvenience in operation. For example, if you need to lift large-sized furniture to the second floor of a building, then this process will be difficult;
• not an easy way to get around. There is no ability to move quickly, as this can be traumatic. However, if you choose a structure of elements with wide and comfortable steps, then the risk of danger is reduced.

Types of construction

A spiral staircase is a structure in which there are no flights between flights, and there is a central support pillar that serves as the basis for the steps. It represents a general cascade of steps.

The production of steel stairs can be carried out with various materials (wood, ceramics, plastic, glass, stone and metal). Spiral metal structures are found the following types: welded, cast, prefabricated and forged. In terms of cost, the last two options will cost more.

By the applied bearing element steel structures can be installed as follows:

• on the bowstring. The supporting element here is a spiral bowstring with steps;
• with central support. Bearing support - column or pillar;
• on kosoura. Carrying beam on which the steps are supported.
