Groove connected repairable low-yield point steel damper

Abstract

The invention discloses a groove connected repairable low-yield point steel damper which comprises a guide rod connecting part, an energy dissipation component connecting part, a sliding guide rod anda protection shell, wherein the guide rod connecting part is connected with a building structure part; a T-shaped groove is formed in the energy dissipation component connecting part; the sliding guide rod is composed of connecting blocks for connecting the guide rod connecting part with the energy dissipation component connecting part; the protection shell is arranged on the sliding guide rod ina sleeving manner and has a T-shaped groove; a U-shaped energy dissipation low-yield point steel plate is arranged between the protection shell and the guide rod connecting part; an energy dissipation low-yield point steel piece with wing edges is arranged between the T-shaped groove of the energy dissipation component connecting part of the sliding guide rod and the T-shaped groove of the protection shell. The damper disclosed by the invention is not only good in energy dissipation and damping effect, but also convenient to disassemble, due to adoption of energy dissipation parts of two different structures, namely the U-shaped energy dissipation low-yield point steel plate and the energy dissipation low-yield point steel piece with the wing edges, the sliding guide rod is moved leftwards and rightwards under the action of earthquake or wind loads to result plastic bending deformation, and thus effects of energy dissipation and seismic mitigation can be achieved.

Description

technical field [0001] The invention belongs to the field of dampers, in particular to a repairable steel damper with a groove connection and low yield point. Background technique [0002] Energy dissipation and shock absorption technology has always been the primary concern of researchers engaged in earthquake work, and the development of new energy dissipation and shock absorption components has become a research hotspot in the field of seismic engineering. The damper made of metal has good hysteresis performance, and consumes a lot of energy in the process of plastic hysteresis deformation. Therefore, designing different construction methods, determining the energy dissipation type of the damper, using new materials and increasing the repairability of the damper after an earthquake have become the main directions for the development of metal dampers. [0003] However, the repairability of traditional dampers is poor. Once the connecting parts of the core energy-dissipati...

Problems solved by technology

[0003] However, the repairability of traditional dampers is poor. Once the connecting parts of the core energy-dissipating parts are damaged, the entire energy-dissipating damper cannot be put into use again. It is necessary to replace the entire damaged damper installed in the building structure to function again The purpose of protecting the main structure
