Nowadays, metal molds are mostly used for molding concrete parts; Because it has many benefits. To connect the forms to each other, a bolt or a molding bolt belt is used, each of which has advantages and disadvantages.
The bolt belt is a part used to connect the shear wall. When the contractor doesn't want to use bolts for formwork in order to create a hole in the wall of the concrete building by using bolts and keep the distance between the forms within a certain limit, he uses bolt belts. In the construction industry, bolt belts are also known as formwork belts and tight belts, which stabilize the forms in place and prevent them from swaying or bending.
Shear wall tight belt features
Bolt straps are used in construction to connect shear walls instead of bolts. The appearance of the bolt belt is in the form of a belt with two punched holes on both sides, and it connects two panels of the metal mold by means of pins and wedges and using a molding belt.
Belt The bolt is made of ST37 steel sheet with a thickness of about 2.5 mm and a width of 2.5 to 3 cm. It should be noted that the length of the bolt belt will vary according to the needs of the contractor and the width of the wall for connecting the metal forms.
Due to the material of the bolt belt, which is made of steel, the strength of the structure is increased and it accelerates the molding process. It will be.
Why is there no hole in the concrete when using the bolt belt?
When the bolt is used in molding, after concreting is finished and the concrete hardens, the bolt must be removed from the concrete, for this reason, holes are created in the concrete, and these holes in the concrete reduce the strength of the concrete, but during use This is not the case with the bolt belt. If a bolt strap is used instead of a molding bolt, the bolt strap will not be removed from the concrete structure after dismantling the molds; As a result, there is no hole that needs to be fixed with concrete.
