Energy dissipation connecting piece for bamboo-wood shear wall

Abstract

The invention discloses an energy dissipation connecting piece for a bamboo-wood shear wall. The energy dissipation connecting piece for the bamboo-wood shear wall comprises an N-type energy dissipation plate, energy dissipation shape memory alloy rods, a belleville spring, a steel gasket, a nut, two fan-shaped connecting piece bodies and a high-strength bolt. Each fan-shaped connecting piece bodycomprises a cross-shaped bottom plate and a fan-shaped connecting plate, and the cross-shaped bottom plates are fixedly connected with the fan-shaped connecting plates. A third through hole is formedin the upper end of the N-type energy dissipation plate, and a fourth through hole is formed in the lower end of the N-type energy dissipation plate. The two fan-shaped connecting piece bodies are located on the left side and the right side of the N-type energy dissipation plate respectively, the upper end of the N-type energy dissipation plate is fixedly connected with the upper end of the outerside of the cross-shaped bottom plate of the right fan-shaped connecting piece body, and the lower end of the N-type energy dissipation plate is fixedly connected with the lower end of the outer sideof the cross-shaped bottom plate of the left fan-shaped connecting piece body. A first through hole is connected with the third through hole through one energy dissipation shape memory alloy rod, anda second through hole and the fourth through hole are connected through the other energy dissipation shape memory alloy rod. The energy dissipation connecting piece for the bamboo-wood shear wall hasthe advantages of being environmentally friendly, renewable in resource, capable of meeting factory prefabrication and easy and convenient to install. Through interaction of the shape memory alloy rods and the N-type energy dissipation plates, the shearing force resistance and the transverse wave consumption capacity are increased, and the anti-seismic property is excellent.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to an energy-dissipating connector for a bamboo-wood shear wall. Background technique [0002] my country is one of the countries in the world where earthquake disasters are very serious. The casualties and economic losses caused by earthquakes are very serious. It is particularly important to seek reasonable and effective earthquake resistance measures. [0003] Under the action of earthquake load, the traditional bamboo and wood structures are mostly elastically deformed without damage, and there is a large stress concentration and deformation at the connection nodes. The traditional connection nodes often cause the connection to be disconnected due to their poor energy dissipation performance. , Material tearing, deformation of bolts and nails, etc., make the performance of bamboo and wood materials not fully exerted, greatly reducing the safety factor of the structure.
