Application of tensile rebar
The beams that are used in the form of blocks on the roofs of buildings have a very high resistance to incoming forces. The block beam consists of two parts: concrete heel and steel truss. The truss consists of five bars. One of the rebars is located at the top and two rebars are placed at the bottom of the truss. The other rebar is placed between the trusses as our ziggurag. The rebars placed at the bottom of the truss are known as tensile rebars and are connected to the zigzag rebar located in the middle of the truss with the help of welding or hooks. This truss shows great resistance against the tensile forces applied to the structure. For this reason, imprecise implementation leads to the lack of resistance of the roof against tensile stresses.
To use rebar in concrete, one should pay attention to many components about it, such as the amount of elasticity and plasticity, yield strength, tensile strength, etc., each of which must be clearly included in the birth certificate or product specification sheet, and the customer It should be informed in order to make the right choice according to the type and location of use in different parts of the building; For example, the tensile rebar that should be used in the lower parts of the steel truss must have high tensile strength so that it can withstand tensile stresses and strengthen the roof.
