Modern manufacturers daily supply a huge assortment of high-quality products to the domestic building materials market, among which I-beams with a special cross-section have recently begun to gain more and more popularity. The role of stiffness here is played by plywood (that is, the OSB blank), which is glued between the bars. Structural gluing is carried out using special glue for wood elements that work under significant loads. I-beam, its technical characteristics we will consider further, refers to the leaders of the most modern and efficient building structures.
Features of an I-beam
I-beam technical specifications is quite high. Due to its special design, this building material acquires an increased level of resistance and rigidity, which makes it possible to use it in places with heavy loads.
The use of I-beams
Due to the fact that the I-beam has the most positive technical characteristics, it has been successfully used:
- in the process of manufacturing interfloor ceilings;
- as the main element in the construction of floors;
- for mounting the attic system;
- for roof construction;
- in the process of erecting a frame structure;
- as a frame for the formwork system (formwork beam).
In each of the applications, this building material acts as the main element, because it takes on considerable loads.
The ability to use the new generation of building elements opens up a great many prospects in the construction field and helps to solve many problems that are related to the environment, the high cost 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 can be characterized both positively and negatively. I-beam wooden beams have a number of disadvantages, however, the possession of many advantages makes it possible to distinguish this material from the rest.
I-beams technical specifications have the following:
- The ability to withstand a huge load. This is facilitated by the characteristic I-section, which has an increased characteristic in comparison with rectangular or circular sections. In addition, I-beams, the technical characteristics of which have a high load capacity, can have a variety of sizes, which makes it possible to choose the optimal length for covering a large span.
- Simple installation process. Due to the special design of the product and its low weight, it is possible to quickly and easily carry out installation work without the use of a lifting mechanism. The weight of I-beams is significantly less than that of a reinforced concrete or metal product, for this reason working with such materials is significantly cheaper and easier.
- Economic feasibility. Due to the relatively low cross-sectional height of the I- beams, the wood is used more economically.
- Low thermal conductivity. Compared to steel or reinforced concrete products, wooden structures retain heat and prevent the penetration of cold.
The dimensions of the material make it possible to easily cope with the load, and give other distinctive technical properties, due to which prolonged operation and the highest load on the I-beams does not lead to a change in its geometric parameters, does not cause deformation and cracking, which significantly prolongs the service life of the structure itself.
I-beam: specifications
Distinctive technical characteristics of the material can occur only if they are used correctly in construction and in compliance with operating rules. Before erecting the ceiling, it is necessary to correctly calculate the I-beams for section sizes, bends and load (taking into account their own), correctly select the appropriate support and fasteners.
The I- beam (I-beam) according to the standard GOST and STO AISU is regulated as follows: GOST - 26020-83, STO AISU 20-93.
What to consider when installing I-beams
Experienced builders know that to block a longer span, a beam with large cross sections may be required - so that the structures do not bend under load. It is imperative to take into account during the installation of the flooring device that as a result of bending, the main load forces act on the lower belts of the beam, working mainly on 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 specialists can make the correct calculations and avoid future deflections of I-beams.
