Swinging self-resetting damper and combined supporting type mounting method thereof

Abstract

The invention discloses a swinging self-resetting damper and a combined supporting type mounting method thereof. The swinging self-resetting damper comprises a vertical cylinder, a steel plate, a butterfly spring, a spring protection cylinder, a horizontal partition plate, a C-shaped damper, a horizontal cross beam, a high-strength pull rod and a fastener. The horizontal partition plate is arranged in the vertical cylinder, and a cover plate is arranged at the upper part of the vertical cylinder; the steel plate is arranged outside the vertical cylinder; one end of the C-shaped damper is connected with the side wall of the steel plate, and the other end of the C-shaped damper is connected with an end plate at the upper portion of the horizontal cross beam; the spring protection cylinder isfixed at the bottom of an end plate at the lower portion of the horizontal cross beam; one end of the high-strength pull rod penetrates through the horizontal partition plate and is fixedly clamped to the top of the horizontal partition plate; the other end of the high-strength pull rod penetrates through the horizontal cross beam and is arranged in the spring protection cylinder; the butterfly spring is arranged at the end, in the spring protection cylinder, of the high-strength pull rod in a sleeving mode and fixed through the fastener; and the vertical cylinder is installed at the bottom of the cross beam. The damper can achieve the energy consumption function through self-swinging, and has the self-resetting capability.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption, and more specifically relates to a swing self-resetting damper and a combined support installation method thereof. Background technique [0002] Driven by the current economic development, my country's urbanization process is accelerating, and the expansion of urban scale and the increase of urban population make the contradiction between man and land in cities increasingly prominent. In this context, medium and high-rise buildings have developed rapidly, and quickly become the mainstream direction of urban architectural development. However, the higher the building height, the greater its own weight, and the poorer its resistance to vibration. If the design of high-rise buildings is still in accordance with the method of ordinary building design, once an earthquake occurs, it will inevitably lead to damage or collapse of the building. cause serious consequences. ...

Problems solved by technology

[0004] Although my country has made great progress in the field of seismic isolation and vibration control of building structures, there are many kinds of seismic isolation products, and the laminated rubber seismic isolation bearings are the majority, but due to the physical defects of the laminated rubber itself, it is only suitable for Horizontal earthquake action has good seismic isolation and shock absorption effect, but it is very difficult to achieve multi-dimensional seismic isolation, and its rotation capacity and pull-out resistance are poor, the self-resetting ability after the earthquake is insufficient, and the rubber aging problem is obvious
