Abstract

The invention discloses a bottom angle damper with a displacement amplification function and an assembled shear wall with a swing energy dissipation function. The assembled shear wall is composed of a shear wall body, an upper connecting plate, a middle connecting plate, a lower connecting plate, a bent steel plate, bolts, an upper supporting arm, a lower supporting arm, a connector, a lead screw, a cylinder barrel, a viscous fluid and a propeller. According to the assembled shear wall structure, a novel damper with displacement amplifying and steering functions is mounted at a weak position of the bottom of the shear wall, and the novel damper is composed of a bending energy dissipation damper, a displacement amplifying and steering device and a viscous energy dissipation damper. The damper has the functions of amplifying the displacement and converting the force in the vertical direction of the structure into the force in the horizontal direction for transmission. The stability and redundancy of the shear wall structure can be improved, so that damage to a main body structure is reduced.

Description

technical field [0001] The patent of the invention belongs to the technical field of anti-shock and shock absorption of civil engineering structures, and specifically relates to a bottom corner damper with a displacement amplification function and a swing energy-consuming assembled shear wall. Background technique [0002] With the sustained and rapid development of the national economy, the steady growth of the housing construction market, the higher and higher requirements for green economy, energy conservation and environmental protection, coupled with the increasing labor costs caused by the aging population, these factors lead to the development of the construction industry facing the pressure of environmental protection and energy conservation. Compared with the traditional cast-in-place reinforced concrete structure, the prefabricated concrete shear wall structure has the same functions and comprehensive benefits, but its assembly construction efficiency is higher and ...
