Problems solved by technology

Through the prefabricated installation method, the increase or decrease of the rod body and the bending damping unit can be adjusted according to the earthquake intensity (or wind load) of the fortification, which overcomes the disadvantage that the number of traditional damper energy dissipation devices cannot be flexibly changed

Abstract

The invention discloses an assemblable curved metal damper, which comprises a central rod, a curved damping unit and a constraining unit, a plurality of curved damping units are arranged on the central rod, and the outer surface of the curved damping unit is connected with the constraining unit; The rod includes several rod bodies, one end of the rod body is provided with a bolt rod, and the other end is provided with a threaded hole, and adjacent rod bodies are connected through the bolt rods and the threaded holes. The bending type damping unit includes an inner confinement ring, a low yield point steel energy dissipation sheet and an outer confinement ring, and the low yield point steel energy dissipation sheet is uniformly distributed between the inner confinement ring and the outer confinement ring along the circumferential direction. The constraint unit includes a baffle, a plate sleeve, and a stiffener is provided at the baffle and the second connecting plate. The assemblable curved metal damper of the present invention has the advantages of modularization, free disassembly, and convenient replacement of energy-consuming devices; the seismic energy is absorbed through the plastic bending deformation of the steel sheet with a low yield point, and the curved damping unit can be adjusted according to actual needs Quantity, improve earthquake resistance.

Description

technical field [0001] The invention relates to a metal damper, in particular to an assembleable curved metal damper. Background technique [0002] In order to reduce the probability of house collapse and damage and improve the earthquake resistance of the building structure, it is an effective solution to install energy-dissipating devices in the structure. At present, the more common energy-dissipating devices include metal dampers and buckling restraint supports. [0003] As an excellent energy dissipation device, the curved metal damper has a simple structure and is easy to install. Through its own inelastic deformation characteristics, it can first yield and consume energy when the structure is subjected to external actions (earthquake action, wind load), thereby ensuring the safety of the main structure. However, in the current engineering application of metal dampers, there are often the following problems: 1. The energy dissipation device is connected with the struc...
