technical field

The utility model relates to a concealed connection structure for clamping and connecting a multi-layer thermal insulation board and a prefabricated column in the field of construction engineering.

Background technique

At present, prefabricated buildings are receiving great admiration and attention in my country. The existing prefabricated building structure is rigid and single in shape, the modules are thick and large, and it is not easy to transport and hoist. Due to factors such as size deviation, the connection performance between modules is unstable, and it cannot be disassembled under normal circumstances. Some components such as the building body cannot be reused, which is not in line with the development concept of green buildings. Moreover, for large-span structures, traditional prefabricated modular components are inconvenient for post-installation and conversion of building functions. The structural thermal insulation integrated board, that is, the SIP composite board, has the advantages of convenient and fast construction, light weight and high strength, earthquake resistance, low thermal conductivity, high flame retardancy, and good sound insulation effect.
