Bowstring - an integral part of the design

To date, most often in residential,production and office premises practice the installation of stairs on the strings. These are high-strength structures that also have an aesthetic appearance. They are metal or wooden. With the help of them, you can transform any interior of the room. One of the main elements of this design is the string for the ladder. Read more about this in more detail.

Design features

Often, a string for stairs is made with dimensions50 mm in thickness, 300 mm in width and in length from 2 to 5.5 m. These structures are fixed in a special way - each step is inserted into the groove of the bearing beam. It is called the string. On the reverse side of the stage is attached to the wall. There is a closed and open type of such structures. In the first case, the presence of risers is obligatory, which are absent in the second form. Most often in such a construction, the steps are made in-between.

To do this, take the string for the stairs, and in itmake holes, the size of which is in the depth of 15-20 mm. These cutouts include risers and treads. And that they fit snugly, the depth of the grooves should be the same. In this design, the lowest step, which is larger than the rest, adds beauty and convenience. On it put elegant carved rails. Also the expressiveness of the stairs is added by a skillfully executed fence. If there are any shortcomings on the steps, they can easily be hidden by a path. Forged structures made of metal are very beautiful.

If the size of the room allows, you canto establish a two-march ladder. However, most often these structures are installed with a direct span, since they are the most simple. For small rooms, a staircase with a screw on the strings is perfect.

Calculation of the staple string

This product, if desired, can be built fromwood or metal. It is very important to correctly calculate the parameters of the bowstring. For example, at a thickness of 50 mm, the size of its overall width will be 300 mm, and the depth of the cut for the step should be made up to 30 mm. To calculate the length of the bowstring, consider the length of the march. The values of the width of the slits and the distances between them are the main characteristics of the ladder, thanks to which it is possible to determine the height of the step, the width of the tread and the angle of inclination. Depending on what kind of staircase design is required, and also taking into account the technical capabilities of the room (interstore distance, width of the march, etc.), various bow strings are made. If a staircase is screwed, then the specified product is calculated and made for it directly at the facility or in the factory.

Product Material

Currently, there is ain the presence of a considerable range of these products. The variety of materials required and the development of new technologies make it possible to produce various types of components to this design. Not an exception is also such a detail as the string for the ladder. Everyone can choose the product to his liking. Buy modern stairs on the strings is possible in many specialized stores. Although many craftsmen purchase component materials and produce them themselves. At present, for the production of such stairs, larch and pine are mainly used. These materials are widely distributed in this field.

Larch is easy to process, rather strong and looks beautiful in the finished product. It is ideal for rooms where there is high humidity.
Pine is hard and strongmaterial. It withstands considerable loads and is also resistant to moist air, as it has a resinous appearance. It is the string for the staircase made of pine is in great demand.

Tip

Analyzing the aforesaid, it is possible with confidencesay that the product can be installed by everyone. There would be a desire. However, it is better to turn to professionals in this field who will perfectly prepare the necessary calculation of the string string and the product as a whole, and then effectively mount the specified structure.
