Problems solved by technology

[0003] However, most of the existing dampers are not repairable. Once damaged, they cannot be put into use after the earthquake, and the dampers must be replaced; moreover, the material recycling process is cumbersome, and the energy consumption method is single, which cannot meet the requirements of buildings under different earthquake levels. Requirements for shock absorber performance

Abstract

The invention discloses a repairable composite metal damper of tooth-shaped and ring-shaped energy-dissipating plates, which comprises a combination of a connecting part of a guide rod connected with a building structure and a connecting part of an energy-dissipating part provided with a supporting block The sliding guide rod formed, and the protective shell sleeved on the sliding guide rod; a number of annular low-yield point steel plates with plastic bending deformation and energy dissipation are arranged between the sliding guide rod and the protective shell, and are connected by groove-type connectors Fixed, the protective shell includes an upper protective shell and a lower protective shell arranged in parallel, and between the upper protective shell and the support block and between the lower protective shell and the support block are provided with meshing friction energy-dissipating sawtooth plates, protective shells and sliding guide rods A first spring and a second spring are respectively arranged between them. The damper of the present invention not only has strong energy consumption and vibration reduction effect, but also is easy to disassemble, and can realize yield energy consumption in stages.

Description

technical field [0001] The invention belongs to the field of metal dampers, and in particular relates to a composite metal damper with teeth and ring-shaped energy dissipation plates which can be repaired. Background technique [0002] Using the secondary system or additional system to reduce the vibration of the main structure is the core goal of the structure damping control theory. Installing the damper in the building structure can make the building structure deform before the main structure under the action of earthquake or wind load, so as to reduce the vibration of the main structure. This is to consume the seismic energy, thereby protecting the main structure. Metal dampers take advantage of the good hysteretic properties of metals after entering the plastic state, and consume a lot of energy during the plastic hysteretic deformation process, which has long attracted the attention of earthquake workers. Designing different construction methods, various energy dissip...
