Energy storage shock-absorbing device

Abstract

The invention belongs to the anti-seismic technical field of building structures, and particularly relates to an energy storage shock-absorbing device comprising a connecting rod, and an upper sleeve and a lower sleeve which are arranged symmetrically; both ends of the connecting rod are respectively connected with the upper sleeve and the lower sleeve through energy storage springs; a first oblique slot and a second oblique slot with consistent orientation are respectively formed on the inner walls of the upper sleeve and the lower sleeve; telescopic latches which are matched with the first oblique slot and the second oblique slot are respectively arranged on both ends of the connecting rod; the telescopic latches can stretch in a direction which is vertical to the connecting rod. According to the shock-absorbing device, due to the matching of the telescopic latches and the oblique slots, the connecting rod can only move gradually in one way relative to the upper sleeve or the lower sleeve, so as to stretch or compress the energy storage springs in the sleeves, store seismic energy which is partially input into a building into the energy storage springs, consume partial seismic energy, and reduce the seismic damage. The device has the advantages of simple structure, strong durability, reusability and high installation applicability.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of building structures, and in particular relates to an energy storage shock-absorbing device. Background technique [0002] Earthquake disasters often have a fatal impact on building structures. In order to make the building structure have a strong ability to resist external damage such as earthquakes, it is often necessary to add anti-seismic devices to the frame structure. The currently widely used passive anti-seismic devices mainly include two types: (1) Energy-dissipating shock-absorbing devices, which achieve the purpose of protecting the structure by dissipating part of the seismic energy input into the structure. Among them, all kinds of dampers, restraint supports, etc., all belong to energy dissipation and shock absorption devices. (2) Vibration isolation and shock absorption device. That is, by means of isolation, the transmission of seismic energy to the structure is avoided o...

AI Technical Summary

Problems solved by technology

[0003] However, the existing anti-seismic devices mainly have the following defects: (1) Most energy-dissipating shock-absorbing devices have losses under the action of earthquakes and cannot be reused

(2) Viscous fluid damper-type energy dissipation and shock absorption devices have durability problems such as aging and volatilization

(3) Most of the shock-isolation and shock-absorbing devices can only be installed in new buildings and are not suitable for existing buildings
