Background Art

Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods.

After searching, a prefabricated building connection structure is disclosed in Chinese patent application number 202120009207.0. The utility model discloses a prefabricated building connection structure. The utility model relates to the field of prefabricated building technology. The prefabricated building connection structure includes a connecting seat, and a mounting plate identical to the connecting seat is provided at the upper end of the connecting seat. A support frame is fixedly connected to the middle part between the connecting seat and the mounting plate, and a concrete layer is paved inside the support frame; the staff first presses the card block into the limit groove, and the limit plate squeezes the telescopic spring to contract, so that the limit block is clamped into the grooves on the left and right sides of the support frame. At this time, the card block can be loosened, and the card block is driven to move the limit plate by the elastic force of the telescopic spring. At this time, the card block can be moved out of the limit groove and enter the inside of the card groove for clamping and fixing. In this way, the prefabricated wall panel is fixed between the connecting seat and the mounting plate, avoiding the connection between the prefabricated building and the prefabricated wall panel by welding or a single bolt, effectively preventing breakage and loosening during long-term use.
