Modern manufacturers dailysupplied to the domestic market of building materials is just a huge range of quality products, among which in recent times I-beams with a special form of section have become increasingly popular. The role of stiffness is played here by plywood (that is, OSB blank), which is glued between the bars. Structural gluing is carried out with the help of special glue for elements made of wood that work under considerable loads. I-beam, its technical characteristics, we consider next, refers to the leaders of the most modern and efficient building structures.
Features I-beam
I-beam specificationshas quite high. Due to its special design, this building material acquires an increased level of durability and rigidity, which makes it possible to use it in places with large loads.
Application of I-Beams
Due to the fact that the I-beam technical characteristics are very positive, it is successfully used:
- in the process of manufacturing floor decks;
- as the main element in the construction of floors;
- for installation of mansard system;
- for the construction of the roof;
- in the process of construction of the frame structure;
- as a framework for the formwork system (formwork beam).
In each of the applications, this building material acts as the main element, because it assumes very considerable loads.
The ability to use building elementsA new generation opens up a great many prospects in the construction field and helps to solve many problems that are associated with the environment, the high price of materials, the high cost of work, as well as the elementary lack of time.
Wooden I-beams: characteristics and features
Any of the building elements maycharacterized by both positive and negative side. Beams I-beams have a number of drawbacks, but the possession of many advantages makes it advantageous to distinguish this material from the rest.
I-beams have the following technical characteristics:
- Ability to withstand a huge load.This contributes to the characteristic I-section, which has a high characteristic compared with rectangular or round sections. In addition, I-beams, the technical characteristics of which have a high loading capacity, can have very different sizes, which makes it possible to choose the optimal length for the overlap of a large span.
- Simple installation process.Due to the special design of the product and low weight, you can quickly and easily perform installation work without using a lifting mechanism. The weight of I-beams is significantly less than that of a reinforced concrete or metal product, for this reason, work with such materials is significantly cheaper and simpler.
- Economical feasibility. Due to the relatively small height of the cross section of I-beams, wood is consumed more economically.
- Low thermal conductivity. Compared with steel or reinforced concrete, wooden structures retain heat and prevent the penetration of cold.
Material dimensions make it easy to handle.with the load, they give other distinctive technical properties, due to which long-term operation and the highest load on I-beams does not change its geometric parameters, does not cause deformation and cracking, which significantly prolongs the service life of the structure itself.
I-beam: technical specifications
Distinctive technical characteristicsmaterials can manifest themselves only if they are properly used in construction and in compliance with the rules of operation. Before erecting the overlap, it is necessary to carry out the correct calculation of the I-beams on the dimensions of sections, bends and load (taking into account their own), to choose the appropriate support and fasteners correctly.
I-beam (I-beam) according to the standard GOST and STO ASChM is regulated as follows: GOST - 26020-83, STO ASChM 20-93.
What to Consider When Installing I-Beams
Experienced builders know that to overlaplonger spans may require a bar with large cross sections - so that the structures do not bend under load. It is necessary to take into account in the process of installing the overlap device that, as a result of bending, the main load forces act on the lower belts of the beam, which mainly work in tension. If the walls are not calculated or the calculations turn out to be erroneous, then as a result of bending they will lose their stability, and the floors will turn out to be of poor quality, “playing”. Only a specialist can make the correct calculations and avoid future deflections of I-beams.
