Beam double-tee: table size, weight and their characteristics

Beam double-tee: table size, weight and technical features - these are the data that will be useful in the construction of civil and industrial use. I-beams are quite varied in their performance. This article provides information on the profiles of the advantages of different materials, their sizes and versions.

Design features I-profile

I-beams - standard beam with a cross section shaped like the letter "H". Modern construction of bridge structures, floors, multi-storey buildings and hydraulic structures is impossible without the use of this type of profile. Also, it is widely used in engineering.

I-profile is a kind of long steel made of high quality steel profile. Typically, in the production of structural steel is used without dopants or with their low content.

I-beams have a different weight and size characteristics. For the classification of the profiles used corresponding numbering and labeling. This facilitates the process of selection of materials, given the characteristics of the object under construction and expected loads on the structure.

Complicated nedoootsenit benefits of using I-profiles. These products are used in various fields, are resistant to high loads, resistance to external influences. They are durable, reliable, affordable. Pleases and pricing of products. The cost of construction, in comparison with analogues, characterized by modesty, which certainly is a plus.

In Frame-house construction are widely used wood I-beams, whose sizes are also diverse. Use of profiles of this material allows to reduce costs for laying the foundation, erection accelerate term structure, and significantly reduce the overall weight of the construction. Application of I-beams made of wood in sawmills preclude further problems associated with shrinkage, shifts structural shrinkage. Made with their own hands wood I-beam to avoid the creaking of the finished structure, precariousness and vibrations inherent in ordinary wireframe buildings.

Important!Beams made of carbon steel designed for use indoors, where not subject to unfavorable weather conditions. To perform external work or at elevated requirements for structural strength, use a beam of low-alloy steel.

Particularly of manufacturing H-profiles

I-profiles produced in accordance with approved regulations. GOST 26020-83 determined moments associated with the manufacture of profiles with parallel faces. Aspects manufacture special purpose profiles regulated GOST 19425-74. Features of the profiles with inclined faces are indicated in GOST 8239-89.

Making your own hands I-beam metal is almost impossible. The manufacturing process is carried out in specialized equipment by hot rolling. The blank for the product are blooms that are processed at a temperature of about 1200 ℃. The specific profile shape increases the strength and rigidity of the product, and to withstand the increased load and distribute it evenly across the surface of the structure.

There is another method of production of H-profiles - welding, when the three of the profile member are joined by welding. This process is fully automated. Welded I-beams have a smaller cross section compared to the monolithic beams. Here you can also combine different grades of steel, reinforcing the only "necessary" areas, which, in turn, reduces the overall cost profile.

Formulas for determining the required weight I-beam

Calculation of mass I-section should begin with determining the weight per meter. The easiest way to find this value in a lookup table STATE gauge, but may be inaccurate due to the metal density.

For the independent calculation of the mass of beams should be considered indicators of space shelves and walls, the density of steel. To determine the distance between the flanges, should be guided by the formula: L = h-2 × t. Calculation of the area shelves occurs according to the mathematical expression: S_P = B × t. To determine the area of ​​the wall using the formula: S_FROM = L × S. To calculate the cross section - S = S c + 2 × Sn. The resulting display section to be multiplied by the average density of steel, which is equal to 7850 kg / m³. All data must first be converted into square meters. S - the wall thickness profile, h - the height of the beam, b - shelf size, t is the average thickness of the flange, L - length of rolled.
