Mortise and tenon structure based on hollow material

Abstract

The invention provides a mortise and tenon structure based on a hollow material. The mortise and tenon structure comprises a hollow main body piece, wherein a circular base is arranged on the hollow main body piece; a transition bulge is arranged on one side of the circular base; a flake card face is formed in the transition bulge; and a clearance is formed between the flake card face and the circular base and can allow another flake card face to be inserted and clamped in the clearance. According to the mortise and tenon structure disclosed by the invention, the circular base surrounding theouter surface of the hollow main body piece is arranged on the hollow main body piece, and the transition bulge and the flake card face are formed in one surface of the circular base, so that the mortise and tenon structure is constructed on the hollow main body piece. According to the arrangement of the circular base, on one hand, the stress tolerance of the hollow main body piece is improved, sothat the thin wall of the hollow main body piece is avoided from being torn or broken after the mortise and tenon structure is mounted; on the other hand, a basis is provided for constructing the mortise and tenon structure on the hollow main body piece.

Description

【Technical field】 [0001] The invention relates to the field of building structures, in particular to a mortise and tenon structure based on hollow materials. 【Background technique】 [0002] Hollow structural materials, mainly used in building materials, furniture, logistics packaging and other industries, such as metal pipes, or a new type of composite material that has been booming at home and abroad this year - wood-plastic materials, which use polyethylene, polypropylene and polychloride Ethylene, etc., instead of the usual resin adhesive, mixed with more than 50% of wood powder, rice husk, straw and other waste plant fibers to form new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce Sheets or profiles. Because the hollow structure material has a hollow structure inside, the hollow plastic profile is a thin-walled structure. It is difficult to nail the connection of two hollow structure materi...

AI Technical Summary

Problems solved by technology

Because the hollow structure material has a hollow structure inside, the hollow plastic profile is a thin-walled structure. It is difficult to nail the connection of two hollow structure materials before. When nailing the thin-walled outer surface of the hollow material, all the connection forces are concentrated on the nail. At the control point, it leads to stress concentration, which easily leads to tearing or rupture of the thin wall. Therefore, the hollow structure material has not yet become the main material of the building.
