Background technique

As a prefabricated exterior wall panel of a prefabricated building, in addition to its enclosure function, it should also have certain strength, rigidity and thermal insulation properties. At present, a sandwich-assembled exterior wall panel with an insulation layer in the middle is usually used. Since both sides of the insulation layer are prefabricated reinforced concrete wall panels, the total thickness of the exterior wall panel is relatively thick. Significant, this requires relatively high hoisting technology and equipment. In addition, the prefabricated reinforced concrete wall panels on both sides are connected through the insulation layer through the connecting piece, which has great requirements on the strength, stiffness and connection performance of the connecting piece itself. high.
