Energy-dissipating sparrow brace internally provided with joint reinforcing and anti-seismic damping device

Abstract

The invention discloses an energy-dissipating sparrow brace internally provided with a joint reinforcing and anti-seismic damping device. The energy-dissipating sparrow brace comprises a soft steel energy dissipator part, two sparrow-brace-type veneers, metal limiting child-mother hanging buckles, a metal fastener and a metal connecting piece; the soft steel energy dissipator part is connected with a beam column by adopting bolts, self-tapping screws or other fasteners; and the two sparrow-brace-type decoration are arranged on the front side and the rear side of a soft steel energy dissipatercorrespondingly and connected with a beam through the metal limiting child-mother hanging buckles, wherein the mother buckles are connected with the beam through fasteners such as screws, and the child buckles are connected with the sparrow-brace-type veneers through fasteners such as screws; and the two sparrow-brace-type veneers are connected by fasteners such as screws through a U-shaped metalsheet. The energy-dissipating sparrow brace has the characteristics of attractive appearance, simple structure and convenient mounting, a new method is provided for designing, repairing and reinforcing of wood structural joints, and the energy-dissipating sparrow brace is suitable for being applied and popularized in wood structural buildings.

Description

technical field [0001] The present invention designs a component for a building structure, and specifically relates to a new type of energy-dissipating bridge with internal node reinforcement and an anti-seismic damping device, which is mainly (but not exclusively) used for anti-seismic reinforcement of mortise and tenon joints in wooden structures before earthquakes, and also It can be used for seismic reinforcement of general wooden structures. Background technique [0002] The existing traditional wooden structure buildings in our country have different structural forms due to different regions. Southern folk houses are mainly represented by piercing wood structures, while official buildings and northern folk houses are mostly beam-lifting structures. my country's southwest, northwest and other regions are earthquake-prone areas, and a large number of existing wooden structures have suffered the test of earthquake disasters. [0003] As a structural component located at...

AI Technical Summary

Problems solved by technology

[0005] The existing strengthening and anti-seismic methods of traditional wooden structures have a single level of shock absorption. When the earthquake force is small, the damper is still in an elastic working state, and the seismic energy is still dissipated by the main body of the wooden structure, causing damage to the entire wooden structure. The damper has no effect. Due to its due effect, under a large earthquake, when the stress is slightly greater than the yield stress, it will enter the plastic energy consumption stage as a whole, and the total energy consumption is small, and the energy dissipation and shock absorption of the damper in stages cannot be realized, and it cannot be compared with the original The architectural style is integrated, and it is difficult to apply in actual engineering
