Earthquake-resistance shock-absorption damping device for building

Abstract

The invention discloses an earthquake-resistance shock-absorption damping device for a building. The earthquake-resistance shock-absorption damping device is characterized by comprising an upper connecting part, a buffer part and a lower connecting part, wherein the upper connecting part comprises a plurality of layers of steel plates, channel steel, an earthquake monitoring alarm device and expansion bolts; the plurality of layers of steel plates are connected with the channel steel by welding; the earthquake monitoring alarm device is mounted on the channel steel; the upper connecting part is fixed with the building by connecting through the expansion bolts; the buffer part is mounted between the upper connecting part and the lower connecting part by welding; the lower connecting part is fixed with the building by connecting through the expansion bolts; the earthquake monitoring alarm device can be used for timely finding occurrence of an earthquake and earthquake intensity; and the buffer part is great in deformation strength and is clear in stress. The earthquake-resistance shock-absorption damping device is creative design scheme, and is beneficial to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of shock absorption of construction engineering structures, and in particular relates to an anti-seismic shock absorption damping device for buildings. Background technique [0002] With the rapid development of social economy, modern buildings tend to be taller and taller, which makes people put forward higher requirements for the seismic performance of building structures, which promotes the continuous deepening of research on domestic engineering structure seismic technology. The traditional seismic method is to set up a large number of The shear wall enhances the rigidity and strength of the structure to improve the seismic capacity of the structure. This traditional method not only affects the building's use function but also increases the difficulty and cost of construction. It may also cause greater earthquake action due to the increase in the mass of the main structure. In addition Existing damping d...

[0002] With the rapid development of social economy, modern buildings tend to be taller and taller, which makes people put forward higher requirements for the seismic performance of building structures, which promotes the continuous deepening of research on domestic engineering structure seismic technology. The traditional seismic method is to set up a large number of The shear wall enhances the rigidity and strength of the structure to improve the seismic capacity of the structure. This traditional method not only affects the building's use function but also increases the difficulty and cost of construction. It may also cause greater earthquake action due to the increase in the mass of the main structure. In addition Existing damping devices generally adopt X-shaped, U-shaped, triangular and other shapes. There are certain defects in the force bearing mode of this shape damping device, which is easy to cause stress concentration and lead to local failure and poor deformation capacity.
