Description

TECHNICAL FIELD

[0002] Prefabricated assembly structures have been widely used in building structures, highway bridges, urban components and other infrastructures in recent years. The mutual connection between prefabricated assembly components is a key component for the structure to withstand loads and deformation. The common connection modes of prefabricated assembly components include mortise and tenon connection, welding connection and mechanical connection mode. However, these connection modes have defects such as excessive connection strength, premature destruction of the connection part and poor cooperative working performance, and therefore a new type of connection structure is needed for prefabricated component connection. The new type of connection structure should have sufficient connection strength and be able to adapt to the deformation difference between adjacent prefabricated components to achieve the purpose of cooperative working.
