Disc spring soft steel energy dissipation and shock absorption device with self-resetting function

Abstract

The invention provides a disc spring soft steel energy dissipation and shock absorption device with a self-resetting function. The disc spring soft steel energy dissipation and shock absorption devicecomprises a rectangular frame, a loading control piece, a soft steel energy dissipation device and a plurality of recoverable disc spring sets which are arranged in the rectangular frame, distributedon the two sides of the soft steel energy dissipation device and arranged on the loading control piece in a sleeving manner; the soft steel energy dissipation device comprises a connecting end, the connecting end is arranged on the portion, in the rectangular frame, of the loading control piece in a sleeving manner, energy dissipation soft steel is fixed to the upper end and the lower end of theconnecting end respectively, and the energy dissipation soft steel is of a hollow closed structure; and the end, away from the connecting end, of the energy dissipation soft steel is fixedly connectedwith the rectangular frame through a clamping bolt. The disc spring soft steel energy dissipation and shock absorption device comprises a self-resetting system and an energy consumption system, can reduce residual deformation of the structure under the small shock condition, and can improve the comfort of the structure under the action of wind vibration; and the disc spring soft steel energy dissipation and shock absorption device can be used for reinforcing various types of supporting structures and joint positions of existing bridges and frame structures.

Description

technical field [0001] The invention is applied to civil and architectural structures, and in particular is a disc spring soft steel energy-dissipating shock-absorbing device with self-resetting function. Background technique [0002] The traditional anti-seismic design of structures uses the anti-seismic properties of the structure itself to dissipate the seismic input energy. Therefore, in order to control the interstory deformation of the structure under the horizontal load within the specified limit, the cross-sectional size of the beams and columns is increased to increase the size of the structure. It is not only uneconomical to use the anti-sway stiffness to resist the earthquake, but also has a certain impact on the practical engineering application of the frame structure, and the main part of the structure will undergo large deformation and damage under the action of rare earthquakes, resulting in the loss of the structure. The use function cannot be continued to be...

It is not only uneconomical to use the anti-sway stiffness to resist the earthquake, but also has a certain impact on the practical engineering application of the frame structure, and the main part of the structure will undergo large deformation and damage under the action of rare earthquakes, resulting in the loss of the structure. Use function, cannot continue to use or restore after the earthquake, resulting in huge economic and property losses
