Building expansion joint which good building expansion joint manufacturer recommends?
Main functions of building expansion joints
Prevent cracks in houses due to climate change. Its practice is to reserve gaps at regular intervals along the length of the building to disconnect the building from the above-ground components such as roofs, walls and floors. Because the building foundation is buried underground and is not affected by temperature changes, it is not necessary to disconnect it. The width of expansion joints is generally 20 cm to 30 cm, and thermal insulation materials are filled in the joints. The spacing between two expansion joints is clearly defined in the building structure code.
If the plane size of the building is too long, it may cause excessive temperature stress in the structure due to thermal expansion and contraction. It is necessary to set a joint on a certain length of the structure to divide the building into several parts, which is called temperature joint. For different structural systems, the spacing of expansion joints is different, and the current Code for Design of Concrete Structures (GB500 10-20 10) has special provisions in Article 8. 1.
Code for design of building expansion joints
According to the code for building design, expansion joints or post-pouring belts should be set for frame-structured houses no matter which direction exceeds 50 meters, and expansion joints should be set for bent structures of 60 meters. The joint width is 30-50 mm, and the building expansion joint is only set for the stability of the building structure. In order to prevent the uneven settlement of buildings from damaging the building structure, this method will be adopted. Not all buildings have expansion joints.
