Hidden type reinforcing and damping energy dissipation device applicable to sidespan mortise and tenon joints of wood structure

Abstract

The invention provides a hidden type reinforcing and damping energy dissipation device applicable to sidespan mortise and tenon joints of a wood structure. The device is used in the mortise and tenonjoints of the connecting portion of a wood beam and a wood column. The device comprises metal steel jackets arranged on the outer periphery of a tenon and the inner periphery of a mortise. The longitudinal cross section of each metal steel jacket in the length direction of the wood beam is trapezoidal, the upper bottoms face the wood column, and the lower bottoms face the wood beam and are in theopen state. A wedge-shaped viscoelasticity rubber block is arranged on the inner side of each metal steel jacket. A through hidden groove is formed in the wood beam in the length direction. A sleeve in which a shape memory alloy wire is arranged is arranged in the hidden groove. The shape memory alloy wire penetrates through the metal steel jackets and the wood column to be anchored by an anchorage device. The device effectively solves the problems that in a traditional method, the shape structure appearance, the tenon and the mortise are extruded and damaged, tenon pulling damage is caused, and self-resetting is lacked, on the premise of not changing the stress characteristic of the mortise and tenon joints, the bearing capacity of the mortise and tenon joints can be improved, the energydissipation ability is improved, the tenon pulling number is reduced, the self-resetting function after shock is achieved, and the service life of the mortise and tenon joints can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of shock absorption and energy consumption of wooden structures of ancient buildings, and in particular relates to a concealed reinforcement and shock absorption energy consumption device suitable for side-span mortise and tenon joints of wooden structures. Background technique [0002] Due to the long history, the wooden structure of ancient buildings has experienced countless unfavorable factors such as wind and rain, earthquakes, wars, and microbial corrosion, resulting in varying degrees of aging and damage. Therefore, the reinforcement and repair of ancient wooden structures is an urgent need. solved problem. The mortise and tenon joints of ancient architectural wooden structures can not only produce a certain amount of rotation but also bear a certain bending moment load. They have typical semi-rigid characteristics. On the one hand, they have good shock absorption and energy dissipation effects. The ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a concealed reinforcement and shock-absorbing energy-dissipating device suitable for side-span mortise and tenon joints of wooden structures, which effectively solves the problem of image structure appearance, mortise and mortise joints in traditional methods. The extrusion damage of the mouth, the failure of the tenon and tenon, and the lack of self-resetting defects can improve the bearing capacity of the tenon and tenon joints without changing the stress characteristics of the tenon and tenon joints, increase the energy dissipation capacity, and reduce the amount of tenon and tenon. Rear self-resetting function can improve the service life of tenon joints
