A mortise and tenon joint of wood structure reinforced by tenon shallow layer planting reinforcement

Abstract

The invention provides a tenon shallow embedded steel bar reinforced wood-structured mortise-tenon joint, and belongs to the technical field of architectural structure engineering. The wood-structured mortise-tenon joint comprises a wood column, a wood beam and reinforcements; the wood column and the wood beam are in mortise-tenon connection through a mode of inserting a tenon of the wood beam in a mortise of the wood column; a row of holes parallel to the wood pattern direction is respectively drilled in the upper and lower surfaces of the tenon of the wood beam; the reinforcements are respectively put in the holes; and structural gluing agents are injected in all the holes to firmly bond the reinforcements with the tenon of the wood beam. The transverse pattern compression bearing capacity and rigidity on the surface layer of the tenon can be improved; the pressed deformation of the surface layer of the tenon is reduced; the embedded reinforcements can resist the pull and pressure stress of the tenon, improve the flexural capacity and the rigidity of the tenon, and improve overall bearing capacity and rigidity of the mortise-tenon joint; the building appearance is not influenced; and the construction is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a mortise and tenon joint of a wooden structure reinforced with mortise and shallow reinforcement. Background technique [0002] Wooden structure is an important architectural form of ancient Chinese architecture, and the use of mortise and tenon joints as the connection method between wooden components is one of the main features of ancient Chinese wooden structures. The mortise and tenon connection is a connection method formed by the combination of concave and convex between wooden components. The protruding part is called the tenon head, and the concave part is called the mortise and tenon joint. . There are many types of mortise and tenon joints, simple ones such as a rectangular mortise on a column, a straight mortise joint formed by inserting a rectangular mortise at the end of a beam into a mortise on a column, complex ones such as multiple compone...

Problems solved by technology

[0007] 1) Affect the appearance of the structure, such as using curved steel plates or metal connectors for reinforcement, it is often necessary to expose the reinforcement materials and affect the appearance of the building

[0008] 2) The above-mentioned plug-in type and dot-matrix mortise reinforcement methods have a better effect on enhancing the vertical bearing capacity of mortise and tenon joints, but because the drilling and slotting operations perpendicular to the mortise destroy the continuity of wood fibers, reducing the tenon The flexural bearing capacity of the mortise and tenon joint is easy to break at the tenon when it is bent
