Despite the development of new construction technologies and the introduction of innovative materials, some classic types of components are still used (laid down) by architects in design projects. Steel (metal) I-beam , it is it that is practically:
- Not in demand in residential construction, where partitions between rooms act as load-bearing structures for the ceiling (floor) slabs of the next floor and the roof.
- It is mandatory for the construction of industrial, entertainment, public buildings and bears the functions of a foundation for the reliable installation of longitudinal or transverse slabs (fasteners).
“Reinventing the bicycle” and replacing an I-beam with a structural element of a different format is simply not practical. Quite simple, but at the same time capable of withstanding significant lateral and torsional loads, it is represented by the Latin letter "H". The product is not subject to shrinkage, like many other building materials, and the bearing capacity is determined based on:
- Dimensional parameters of the I-beam itself.
- The thickness of the metal used in the manufacture.
- Grade used for production, steel or alloy.
At the same time, an architect planning to use steel I-beams as the basis for floors must also take into account such a component as the technological method of their manufacture. There are 2 main types.
Welding technology
Sheet steel of the required thickness is cut into strips to fit the dimensions of the structural components of the I-beam. The final connection is done using:
- Manual electric welding.
- Gas welding equipment.
- Innovative laser machines.
This type of beams is used in the construction of low-rise (not high-rise) buildings or structures, taking into account the additional tolerance to the possible maximum load on the structure.
Hot and cold rolled steel
This technology for the manufacture of I-beams is used at metallurgical enterprises. It implies the use of high-tech in the manufacturing process:
- Rolling mills.
- Pressing equipment.
In this case, the final products (I-beams) are qualified according to the approved quality standards - A (high accuracy) and B (normal accuracy) with the corresponding indication of the parameters in the technical passport of the batch.
The use of I-beams as subfloors has a number of significant advantages over reinforced concrete trusses. These include:
- Low st�
