Wooden I-beam. Technical characteristics, application
Modern manufacturers dailysupplied to the domestic market of building materials is simply 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 glued 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 consider below, refers to the leaders of the most modern and efficient building structures.
Features of the I-beam
I-beam technical characteristicshas high enough. 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.
Application of I-beams
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 the 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 building elementsthe 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 cancharacterized both from the positive and from the negative side. 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 increased 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 sparingly.
- Low level of thermal conductivity. Compared with the product of steel or reinforced concrete, wooden structures retain heat and prevent the penetration of cold.
The dimensions of the material can be easily handledwith load, give and other distinctive technical properties due to which long operation and the highest loading on I-beams does 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 characteristicsmaterial can be manifested exclusively when properly used in the construction and compliance with the rules of operation. Before erecting an overlap, it is necessary to correctly calculate I-beams for sectional dimensions, bends and loads (taking into account own), to properly select the appropriate support and fasteners.
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 covera longer span may require a beam with large cross sections - so that the structures do not bend under the load. It is mandatory during the installation of the overlap device to take into account 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 of I-beams can only specialist.
