X-shaped soft steel energy dissipation device with assembled self-resetting combined disc spring

Abstract

The invention provides an X-shaped soft steel energy dissipation device with an assembled self-resetting combined disc spring, and belongs to the technical field of civil engineering disaster prevention and shock absorption. An X-shaped soft steel damper (5) is fixed to the inner side of an outer sleeve (4) and the outer side of an inner sleeve (3) through high-strength bolts (10). The combined disc spring (6) is arranged between the inner sleeve (3) and the outer sleeve (4) in a penetrating and sleeving mode. The inner sleeve (3) and the outer sleeve (4) slide relatively, then an outer stop block (7) and an inner stop block (8) are driven to push a baffle (9) to slide oppositely, and finally the combined disc spring (6) is extruded, so that the combined disc spring (6) is always in a pressed state no matter whether the device is pulled or pressed, and when the inner sleeve (3) and the outer sleeve (4) slide relatively, the X-shaped soft steel damper (5) is also driven to deform. During an earthquake, the X-shaped soft steel damper (5) can effectively dissipate earthquake energy, and after the earthquake, a self-resetting part can help the structure to restore the original state, and residual deformation is eliminated.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of civil engineering, and is an energy-dissipating and shock-absorbing member applied in the field of structure and bridge engineering. The assembled self-resetting combined disc spring X-type mild steel energy-dissipating device has good energy-dissipating ability and self-resetting ability. Background technique [0002] Earthquake, as a serious natural disaster, can cause damage or even collapse of building structures, which poses a serious threat to people. Building earthquake resistance has always been an important topic. In 2011, Chinese scholars clarified a new concept of structural seismic design—recoverable functional structure. A recoverable functional structure refers to a structure that does not need to be repaired after a fortification or a rare earthquake, or can be restored to its function after a little repair in a partially used state, and the structure is easy to build and ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the large residual deformation of the traditional support under the action of a large or moderate earthquake increases the cost of post-earthquake maintenance and reconstruction. For this purpose, an assembled self-resetting combined disc spring X-type soft support is proposed. Steel Energy Dissipator
