Hidden type wood beam column joint reinforcing device and reinforcing method thereof

Abstract

The invention discloses a hidden type wooden beam column joint reinforcing device and a reinforcing method thereof in the technical field of wooden building repair, the reinforcing device comprises an FRP rib, magneto-rheological plastomer springs are arranged at the two ends of the FRP rib, a layer of hexagonal iron sheet is arranged on the outer side of each magneto-rheological plastomer spring for wrapping, and the hexagonal iron sheet is filled with magneto-rheological fluid; the high-strength bolts penetrate through the hexagonal iron sheet to be fixedly connected with the small logs and the FRP ribs to be fixedly connected with the hexagonal iron sheet, the thin memory alloy diaphragms are attached to the two sides of the hexagonal iron sheet respectively, the small quadrilateral iron containers are attached to the outer layers of the thin memory alloy diaphragms, and the small quadrilateral iron containers are filled with magnetorheological fluid. The quadrilateral iron small container is connected with a sleeve on the outer side, and then the sleeve is connected with a beam column. According to the reinforcing device, the flexural capacity and rigidity of the beam-column joint are improved, meanwhile, earthquake or wind vibration energy can be dissipated through the damping energy dissipation effect, and the original semi-rigid characteristic of the mortise and tenon joint is kept.

Description

technical field [0001] The invention relates to the technical field of wooden building restoration, in particular to a concealed wooden beam-column joint reinforcement device and a reinforcement method thereof. Background technique [0002] Chinese ancient buildings are mainly wooden structures, and many of the beam-column joints of these buildings have bird replacements, and the bird replacements mainly play a decorative role. At present, the reinforcement method of beam-column joints in China is mainly to use ordinary steel for reinforcement, such as adding section steel directly at the beam-column joints, or wrapping the beam-column joints with steel plates for reinforcement. These reinforcement methods are obviously not friendly to the wooden structure of ancient buildings. The overall structural characteristics of wooden buildings are flexible. Direct reinforcement of profiled steel or outer steel plate will make the overall wooden structure no longer belong to a semi-r...

AI Technical Summary

Problems solved by technology

This reinforcement method does not greatly improve the overall seismic performance of the structure, and may even reduce the seismic performance of the overall structure.

In addition, after a period of time, the simple steel or steel plate reinforcement may corrode the steel, which will greatly affect the bearing capacity of the overall structure and affect the overall aesthetics of the building.
