Sale of beams at Ardebil Tiring Store
The most important and in a way the most widely used construction profile produced from iron can be considered iron beam, which has a cross-section in the shape of the English letters I and H. The main component of the construction of metal frame buildings is the iron beam and generally The ability to build a metal frame building is considered impossible without the presence of beams.
The task that is defined for beams in building construction as a structural component is to bear and transfer the loads that are imposed on the building.< br>
Girders consist of two parts, wing and web, the middle part of the beam, which is also considered as the main part, and the edges and sides of it are called wings.
The benefits of using beams in construction
The advantages of using iron beams in construction are numerous. The first thing is that beams are prefabricated parts in steel factories that are industrially produced and the possibility of production errors in the workshop cannot be imagined for them. Also, due to their readiness, the speed of work in metal frame buildings is much higher and the execution and installation of beams is done at a very high speed. Also, it is much easier to use beams in high-rise and high-rise buildings.
Another important point in the field of using beams in the construction of metal frame buildings is that after the construction of the structure is completed, it is possible to develop in The next steps are ready. Also, one of the advantages of using steel beams in construction and the construction of metal frame buildings in general is that iron profiles occupy less space than concrete structures, and in this sense, they are economical.
The most used beams in the building industry
Beams are made in different types and have a relatively large variety. Most of their diversity is in terms of appearance and mechanical properties, and each type is suitable for use in a specific industry. In this section, we are going to point out the most widely used types of steel beams in the construction industry:
IPE iron beam
IPE profiles, which look like the English letter I, are also called regular beams. The production of IPE beams is based on European standards and their wings have a fixed thickness. Most of the structures that are conventionally designed and built in Iran are designed according to the same standards and with the same initial and final wings. For this reason, the use of IPE profiles is very common in Iran.
Black beam
This type of profile is also I-shaped, and of course it is produced according to Russian and Chinese standards in iron smelting and steel manufacturing factories. The difference between this profile and IPE is the thickness of the wing, which in this type of profile is the thickness The wing will decrease as we move away from life. Both of these types of I-shaped profiles are produced and offered to the market in the steelmaking and iron smelting industries of our country.
Winged wings or Hash h or iPB
I or H-shaped steel profiles are called beams. If the wing of the iron beam is equal to its life, the beam is called a wide beam or hash, and it is also called IPB. Here, the meaning of beam joist is the height of the back to the back of the beam. In other words, the thick sheet placed between the wings of the beam is called joist. These beams are produced with different standards, the most important of which is the European standard, and in Iran, the European standard is followed for the production of these iron profiles.
These types of beams are classified into three main categories. which are: heavy wide wing beam HEB, light wide wing beam HEA and heavy beam TPB. Generally, heavy wing beams are thicker than light wing beams. These beams are produced in different sizes from 10 to 1000 and offered to the market.
Honeycomb beam
The name of this type of beam is the presence of empty holes throughout its life, which look like a bee nest. The reason for the presence of these cuts and holes in the core of this type of beam is to create resistance against the bending anchor. Also, the space between these holes can be used to pass electrical pipes and installations, and in this sense, they have an advantage. And they will be more economical. But they also have their own disadvantages, and the same holes that cause advantages also cause them to be weak. Because the shear resistance decreases due to the presence of holes in their cores, especially at the connection point of the bridge to the columns, and they are forced to use metal sheets to fill these holes. Also, the presence of these holes on the surface of the beam causes their resistance to shear stress to decrease drastically.
