Usually used simple crossing. without additional reinforcement vertically and horizontally, which does not ensure the strength of the entire foundation.
To prevent this from happening, additional reinforcements should be used in the form of U-shaped or G-bent rods, which are used at the joints of the reinforcement. There are many schemes for their location.
Cross rods are placed twice as often as in the middle.
If it is necessary to reinforce an obtuse angle, then several L-shaped rods should be used. arranged in a certain way. The design is reinforced with additional crossmembers.
There are two ways to connect steel rods together.
Welding is a quick and not difficult process, but it has several disadvantages:
- Due to the high temperature, the properties of the metal change.
- In order for the welding units to be strong , high qualification of the welder is required.
- Welding enhances the rigidity of the structure. thereby increasing the probability of violating its integrity when pouring concrete.
