Wooden I-beam. Technical characteristics, application

Modern manufacturers daily delivered to the domestic market of building materials just a huge assortment of quality products, among which in recent years, ever increasing popularity began to conquer I-beams, which have a special form of section. The role of rigidity here is played by plywood (i.e., OSB billet), which is pasted between the bars. Structural gluing is carried out with the help of a special glue for elements made of wood, which work under considerable loads. I-beam, technical characteristics of it, we will discuss further, refers to the leaders of the most modern and efficient building structures.

Features of the I-beam

I-beam technical characteristics are 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 high loads.

I-beam application

Due to the fact that the I-beam technical characteristics are the most positive, it is successfully applied:

• In the process of manufacturing interfloor overlappings;
• As the main element in the construction of floors;
• For installation of the attic system;
• For roof construction;
• In the process of erecting a frame structure;
• As a frame for the formwork system (beam formwork).

In each of the applications, this building material acts as the main element, because it takes on very considerable loads.

The ability to use the building elements of the new generation opens up a great many prospects in the construction field and helps to solve a lot of problems that are associated with ecology, high price of materials, high cost of work, and an elementary shortage of time.

Wooden I-beams: characteristics and features

Any of the building elements can be characterized with both positive and negative sides. I-beam wooden beams have a number of drawbacks, but the possession of many advantages makes it possible to select this material favorably among the rest.

I-beam technical characteristics are as follows:

• Ability to withstand a huge load. This is facilitated by a characteristic I-section, which has an enhanced characteristic in comparison with rectangular or circular cross-sections. In addition, I-beams, whose technical characteristics have a high load capacity, can have a variety of sizes, which makes it possible to choose the optimal length for overlapping a large span.
• Simple installation process. Due to the special design of the product and a small mass, it is possible to quickly and easily perform installation work without the use of a lifting mechanism. The weight of the I-beams is considerably less than that of a reinforced concrete or metal product, for this reason the work with such materials is significantly cheaper and simpler.
• Economic feasibility. Due to the relatively small height of the cross-section of the I-beam beams, wood is consumed more economically.
• Low level of thermal conductivity. In comparison with the product made of steel or reinforced concrete, wooden structures retain heat and prevent the penetration of cold.

The dimensions of the material make it easy to cope with the load, and give other distinctive technical properties, due to which prolonged operation and a high load on I-beams do not lead to a change in its geometric parameters, does not cause deformation and cracking, which significantly extends the service life of the structure itself.

I-beam: technical specifications

Distinctive technical characteristics of the material can be manifested only if they are used correctly in the construction and maintenance of the operating rules. Before erecting an overlap, it is necessary to perform the correct calculation of I-beams for the sizes of sections, bends and load (taking into account one's own), to properly select the appropriate support and fixing elements.

I-beam (I-beam) according to the GOST and STO ACHM standards is regulated as follows: GOST-26020-83, SRT ACHM 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 the load. It is necessary to take into account in the process of installation of the overlap device that as a result of bending the main load forces act on the lower belts of the bar, working mainly on tension. If the walls are not calculated or the calculations are erroneous, they will lose their stability as a result of bending, and the floors will turn out to be of poor quality, "playing". Make the correct calculations and avoid in the future deflections I-beams can only specialist.
