What is an Industrial Join?
The beams are parts that are used in the roof of structures, and their main purpose is to bear the dead and live load of the roof. Beams are produced in different types, such as concrete beams, chromite beams, and prestressed beams. The main members of the concrete beam are concrete and steel sections. The industrial beam is the concrete beam that is manufactured using industrial methods.
In industrial beams, spot welding is used to make trusses, which causes less breakage in the beam; But in the traditional beam, electric arc welding is used. Basically, the components of the industrial beam are straight and there are no curves in their path. The components of this beam are connected to each other by hinges.
Comparison of Industrial and Traditional joists
The first difference between an industrial beam and a traditional beam is the type of connection of their metal sections. Spot welding method is used in industrial beams, which reduces the fracture in the beam. But in traditional joists, electric arc welding is used, because the reinforcements in the joists contain carbon, the use of this welding causes the joists to become brittle. Among other differences between industrial and traditional joists, we can point out that, as the name suggests, These two come up, making industrial joists is a mechanized and fully automatic process, but traditional or manual joists are made by humans. Due to the mechanization of the industrial beam manufacturing process, the amount of errors and mistakes is minimized. This also increases the speed of production of beams.
Shear bars that are produced in an industrial way have high precision. This is despite the fact that the bars of beams that are produced manually are mostly asymmetrical and cause the beam to twist. But because the machine is used in the production of industrial beams, the beam will have balance and symmetry, and as a result, because the internal forces are aligned, the beam will not buckle.
Another difference between industrial joists and traditional joists is that in traditional joists, if the zigzag bars are asymmetrical, the connection with the upper wing is cut when the shear diagonal member is separated from the upper bar. While in industrial beams, in case of such an event, the connection with the upper wing is maintained and the beam can still bear the load of the roof. To add to the length of the beam, in traditional beams, zigzag bars must be welded together. connect that this will cause discontinuity along the length of the beam. But in the industrial beam, this work can be done by using transverse coil rebar and maintaining continuity along the length of the beam.
benefits of industrial joists
- Join Weight Loss and as a result the final weight loss of the structure implemented with
- Reduction of the cost of joining and reducing the price of joists
- Reducing joists
- Increased joist quality
concluding
Different types of beams can be used to make a block beam roof. Industrial joists are a type of concrete joists that are named because of their production method, which is completely mechanized compared to the traditional method. In the production of industrial beams, spot welding is used instead of electric arc welding. This issue, along with the fact that the accuracy of manufacturing industrial beams is high, has caused many advantages in them.
