Repairable tooth-shaped and ring-shaped energy-consuming plate composite type metal damper

Abstract

The invention discloses a repairable tooth-shaped and ring-shaped energy-consuming plate composite type metal damper. The repairable tooth-shaped and ring-shaped energy-consuming plate composite typemetal damper comprises a sliding guide rod and a protective shell, wherein the sliding guide rod is formed by combining a guide rod connecting part and an energy-consuming piece connecting part; the guide rod connecting part is connected with a building structure piece; a supporting block is arranged on the energy-consuming piece connecting part; the protective shell is arranged on the sliding guide rod in a sleeving way; a plurality of plastic bending deformation energy-consuming ring-shaped low-yield-point steel plates are arranged between the sliding guide rod and the protective shell and are connected and fixed through a groove-shaped connecting piece; the protective shell comprises an upper protective shell and a lower protective shell which are arranged in parallel; friction energy-consuming sawtoothed plates which are engaged with each other are arranged between the upper protective shell and the supporting block as well as between the lower protective shell and the supporting block; and a first spring and a second spring are arranged between the protective shell and the sliding guide rod correspondingly. The damper has strong energy-consuming and damping effects, is convenient to disassemble and can realize staged yield energy consumption.

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...

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.
