Connecting device and method for replacing traditional mortise and tenon joint

Abstract

The invention provides a connecting device and method for replacing a traditional mortise and tenon joint, the device comprises a node part and a connecting part, and also comprises a column (1) and abeam (6) ; one end of the column (1) is connected with the node part; one end of the beam (6) is connected with the connecting part, and the connecting part is connected with the node part; comparedwith the prior art, the connecting device has the advantages of convenient processing and simple construction; the force transmission path is clearer, the stress of the node is clear, and the structure calculation is simple; multiple roof beams on the same plane can be intersected at one point, and the adverse effect of the eccentric bending moment is avoided; and the connection efficiency is improved, 'strong node and weak rod' is effectively achieved, and the anti-seismic performance of the whole structure is ensured.

Description

technical field [0001] The invention relates to the field of reinforcement devices, in particular to a connection device and a method for replacing a traditional mortise and tenon joint. Background technique [0002] The connection between the wooden structural components of ancient buildings adopts the traditional mortise and tenon connection. It is characterized by: [0003] 1. A connection method that does not use metal and relies on the "squeeze pressure" and "shear resistance" between wood to transmit force. [0004] 2. The completed connection parts are kept in harmony with the original components, and the appearance is simple and beautiful, but the processing is complicated and the technical requirements are high, and the mechanical properties of the connection parts are affected by the processing accuracy. [0005] 3. Compared with the stiffness and strength of wood, the stiffness and strength of mortise and tenon connection are less than 10% and less than 50% high...

Problems solved by technology

[0004] 2. The completed connection parts are kept in harmony with the original components, and the appearance is simple and beautiful, but the processing is complicated and the technical requirements are high, and the mechanical properties of the connection parts are affected by the processing accuracy

[0005] 3. Compared with the stiffness and strength of wood, the stiffness and strength of mortise and tenon connection are less than 10% and less than 50% high, often appearing that "the joint is weaker than the bar".

[0008] For example, the patent document CN105781138A discloses a steel assembly reinforcement device for wooden structures of ancient buildings that allows sliding of mortise and tenon joints. Although this technical solution improves the performance parameters of traditional mortise and tenon structures, it still cannot completely overcome the lack of strength of the wooden structure itself. question

[0009] Another example is the patent document CN201437643U, which discloses a reinforcement device for mortise and tenon joints in the ceiling of ancient building wooden structures. Although this technical solution is better for wooden construction protection and less destructive, it also has a certain reinforcement and protection effect, but the joints The strength is still lower than that of the rod, and there is still room for optimization of similar reinforcement devices
