Kosouur - what is it? Flight of stairs. Steel Koser

In my own home I want to do everything so that the eye rejoices. The feeling of coziness and comfort should be present everywhere. Therefore, to create an interior should be approached with all thoroughness. Or maybe you have a mansion on several floors? Or at the entrance to the house is a beautiful staircase, which will soon need to be repaired? Then in this situation, the focus should be on Kosovars. It is about them that will be discussed in this review.

What does the term hide?

Those who have a need to repair their own housing, can ask one simple question: kosour - what is it? Under this term, the most popular type of supports is used, which is used in the construction of stairs. It has the appearance of a beam and is located on each ladder march, which secures the steps. In general, this entire structure serves as a support for the ladder. It is necessary to consider this element in more detail, answering the question: "Kosoura - what is it?"

What can I use except Kosoura?

Due to such a detail it is possible to give beauty and originality to the whole ladder as a whole. Among other things, there is another type of similar structure. He wears the name of a string. It is very similar to kosuro, but the installation of the tread comes from the inside. The connection that attaches the entire structure as a whole is due to puffs.

In addition, from the bowstring kosoury wooden differ both in size and species. These parameters are completely dependent on the shape of the steps, and also on the load on the ladder, which is permissible. All these factors play a rather important role. And it should be noted that the simultaneous load on the interstreet and entrance ladders should not be more than 250 kilograms.

An important step associated with the calculation part

It should be thoroughly approached to such a procedure as calculation of kosoura. On average, it should not be less than 50 mm in width. This is the case if the width of one march does not exceed one meter. If this parameter is equal to 1.25 meters, then the width of the Kosovra itself should reach 60 mm. At the width of the march, equal to one and a half meters, the kosour must be 70 mm. In this paragraph, it is also necessary to note that when using a bowstring, the width of the stairwell is much larger than in the case of a strut.

How is the production of wooden elements?

It is impossible not to mention the methods of production, answering the question: "Kosouur - what is it?" There are two variants of production.

1. Taking into account the length of the march, it is necessary to form beams (blanks). Such parameters as the thickness and width of oblique lines should not be too large. In addition, a triangular comb shape is created (this is the place where the steps are fixed). Its dimensions should be selected depending on the lift pitch. We must also take into account the width of the tread along with the thickness of the beam. The fastening of steps and struts in this situation is due to dowels. They are fixed in specially created grooves by using glue. As a result of all these actions, a beautiful staircase with elegant socks will be obtained. This technology allows you to save on the purchase of expensive material.
2. In this case, the width of the workpiece must exceed the overall width of the Kosowra itself. Its length should correspond to the length of the whole march as a whole, and the thickness to be equal to the thickness of the future Kosoura. Therefore, it is important in this situation to determine in advance what the size of the final product should be. To accurately comply with all sizes, it is worth using such a procedure as milling. This technology from the first is characterized by a higher production speed.

What kinds of Kosovar can be distinguished?

It should be noted that, unlike the bowstring, wooden kosoury - lighter. In addition, they take up less space. In this regard, in many mansions, it is the Kosovars that are used, especially if the ladder shaft is small.

There are several varieties of wooden obliques. Direct elements are used in case of using exactly the same marches. The comb is necessary in the event that it is planned to place the overhead stairs. Rounded oblique shoes are required if there is a desire to give roundness to the entire ladder.

In what cases is a fence required?

Stairs in which the bowstring is used can be equipped with a guard rail in the following cases:

1. When the baluster is mounted directly on the bowstring.
2. When large sizes are characteristic for the baluster, and not for the bowstring. In this case, a sub-board is attached to the ladder element, which helps to extend the string by about 25 mm. Later the baluster is also mounted on this board.
3. On the sides of the bowstring is fastening balusters, the length of which in this case increases. However, this technique contributes to the liberation of the width of the march. Free space is released for the staircase.

Above, the advantages that characterize the attachment of Kosovars in many houses are listed. There is an opinion that these elements impart greater reliability to the entire structure as a whole. A ladder with a string can be made in a shorter time.

Which parameter is decisive?

The main characteristic that kosour possesses is strength. And it should be noted that this parameter is specific. It is necessary to understand that this element must safely withstand the weight of people and those goods that a person will lift up the stairs. However, there should be no unnecessary vibrations. Know that that kosour, which trembles or sways, is not qualitative. Most likely, somewhere there was a mistake.

Recently, the staircase on a metal kosour has become popular. It has very high strength and reliability. All the necessary elements can be purchased at the metal warehouse. Their production is a method of welding from a channel or a tube of rectangular shape of a rather large size.

If there is no experience, it is better to trust professionals

To produce a metal oblique metal, it is necessary to have experience in this field. In the event that previously you did not work with him, you do not need to take risks. The probability of marriage in this situation is quite high. After all, today there is an opportunity to purchase absolutely any kosour, of any type and of any material, in the construction market.

Can I use one beam in the stairwell?

In the event that you plan to use one kosour, which will be placed in the center of the march, then instead of wood it is better to use metal. Kosoryur steel will make the stairs more stable than in the case of wood. In addition, the steps at the ends will not bend. What is bad about wood is that it will not be possible to install any additional fastening systems. In the case of using metal, this will be very easy to do. An element made of steel is able to become the only one in the whole construction, and it is also quite easy to restrain all the load. For additional stability of the stage it is necessary to strengthen it by means of special plates. Do you want to see how the staircase march will look like in such a situation? The photos show it to you.

Elements made of metal are produced by using welded parts. You should also use an I-beam, a channel or a rectangular tube. In addition, Kosovars made of metal can take a variety of forms. It is not necessary to use direct elements. Quite often you can see stairs, which are twisted around one support. Steps in this case are performed in such a manner as "goose step".

Still, it is better to use several metal elements

In large-scale staircases, you should still use two Kosowra. They have a positive effect on the external design, as they are more easily perceived from the visual side. In such situations, the staircase looks lighter and airy. To achieve this effect, manufacturers use the metal of a certain texture and color when creating the oblique metal. In addition, it looks more elegant in design than wood.

The owner's desire is decisive in choosing a staircase

The choice of such an element as a kosour, in many respects will depend on the tastes and preferences of the owner of the house. A beautiful design can be made from both wood and metal. In addition, when choosing such an essential element, it is necessary to be guided by the goals for which the ladder was created. No less important is its shape. So, choosing socks and material for their manufacture, it is necessary to consult with specialists. They will advise you on the use of such a complex and important element in the design.

Conclusion

In this review, an attempt has been made to understand the question: Kosovo - what is it? We hope that the article helped you understand what this element represents and what role it performs in the stairwell.
