Sparrow brace imitating reinforcing structure for reinforcing wood structure joint and manufacturing method thereof

Abstract

The invention discloses a sparrow brace imitating reinforcing structure for reinforcing a wood structure joint and a manufacturing method thereof. The sparrow brace imitating reinforcing structure for reinforcing the wood structure joint comprises angle arm steel plates, a reinforcing connector and arc-shaped arch steel. The number of the angle arm steel plates is two. One ends of the two angle arm steel plates are hinged, and connecting lug plates are arranged at the other ends of the two angle arm steel plates correspondingly. The two angle arm steel plates are further provided with external connectors connected with the wood structure joint. A spiral-shaped spring portion is arranged at one end of the arc-shaped arch steel, and the spring portion and the other end of the arc-shaped arch steel are connected to the connecting lug plates of the two angle arm steel plates correspondingly. A reinforcing area is formed among the two angle arm steel plates and the arc-shaped arch steel. The reinforcing connector is located in the reinforcing area and fixedly connected with the two angle arm steel plates. The sparrow brace imitating reinforcing structure greatly improves the rigidity, bearing capacity and deformability of the wood structure joint and enhances the energy-dissipating capacity of the wood structure joint, thereby greatly improving the anti-seismic property of the wood structure joint.

Description

technical field [0001] The invention relates to a building reinforcement structure and a manufacturing method thereof, in particular to a pseudo sparrow reinforcement structure for reinforcing wooden structure nodes and a manufacturing method thereof. Background technique [0002] Due to the effects of external forces (earthquakes and typhoons) and natural environments (rain, sunlight, snow erosion or microbial damage) on wood components to varying degrees of damage or aging, reinforcement technology is more and more widely used in wood structure buildings. However, in the earthquake damage investigation of ancient wooden buildings, it was found that some structures were severely damaged or even collapsed as a whole, and the damage was mainly concentrated in the node area, which was the weak link in wooden structure buildings. The force of the joint area is complex, and it is difficult to carry out reinforcement construction inside the joint (especially the place where the m...

Problems solved by technology

Among them, the fiber cloth reinforcement method requires the use of structural adhesives, and the pasting technology for nodes with complex structures is a difficult problem in the reinforcement construction; the nail or flat steel reinforcement method, the curved steel plate or steel pin reinforcement method, and the beam bottom bracket reinforcement method will be Cause damage to the original components and speed up the damage of components during the earthquake damage process

[0004] The traditional method of reinforcing wood structure joints with steel has outstanding advantages: steel has high tensile strength, good ductility, and can enhance the stiffness and deformation capacity of wood structure joints; at the same time, it also has obvious disadvantages: damage to the original components, and it is not beautiful
