Metal beam refers to a special type of high-quality rolled metal and is mainly used to create large-span structures of industrial buildings, which can significantly reduce the overall load on the base of the building. Today it is one of the most important components of any work sites, crane beams, bridges, ceilings and other types of metal structures.
Each type of this product has its own characteristics, which allows you to make the right choice. It must meet the requirements for technical characteristics in order to be able to create the necessary design. In modern construction, a metal beam is widely used. Its selection is carried out according to such criteria as the size of the walls, shelves and appearance.
Metal beam is produced in two main types. The main difference lies in the different shape of its section - this is a T-beam and an I-beam. The T-beam, when viewed from the end, resembles the letter "T", while the I-beam - the letter "H" or double inverted letters "T", for which, however, it got its name. Mainthe scope of both - as load-bearing floors of buildings and structures for various purposes.
In construction, a metal beam helps to redistribute the load on the supporting structures. They then evenly transfer it to the foundation. A metal beam is a kind of skeleton of a building, which is gradually filled with other structural building materials. That is why special requirements are imposed on the quality of manufacture of this element. The classification of this type of rolled metal is based on technical characteristics:
- in the form it has;
- according to the thickness of the shelves and walls;
- depending on the location of the edges of the shelves;
- according to the material used to make it.
In addition, the metal beam differs in purpose and manufacturing method.
A beam can be called a kind of beam, which has a variety of sizes and cross sections. It was created specifically for the possibility of distributing the load on the supporting structures evenly around the entire perimeter of the building under construction. Recently, a metal I-beam has become widespread, which is widely used in the construction of overpasses, bridges, hangars, warehouses, not to mention industrial and civil facilities.
An important point in making a choice for holdingconstruction is the correct calculation of the metal beam. Regardless of the material, type of section and type of structure, its calculation is carried out according to one algorithm. First, a design scheme is drawn up, then internal forces are determined. The next step - according to internal forces, the beam section is selected and at the final stage all the results obtained are checked. Verification allows you to increase or decrease the cross section in order to achieve the optimum degree of strength.
