Currently, the joining of structural members of metallic construction relies mainly on two traditional ways of welding and bolting/bolting. This approach, while mature in application in engineering practice, has inherent technical drawbacks. The ultimate strength of the welded joint is far lower than that of the metal base metal in a welding mode, so that the integral rigidity and bearing capacity of the structure are limited, the peg/anchor bolt connecting mode belongs to split connection, the connecting piece is easy to break/loosen under power load, and the base metal is required to be drilled and damaged. The welding-free and stud-free metal mortise and tenon structure can enable the joint to be integrated with the whole structure, the joint is more tightly connected under the load effects of collision, earthquake, typhoon and the like, and the integral strength and rigidity of the whole sheet metal equipment/building can be ensured.
