Abstract

The invention discloses a bridge damper convenient to replace. The bridge damper comprises two fixing plates, two fixing devices and a liquid damper, the two fixing devices are arranged on the top walls of the two fixing plates correspondingly, the liquid damper is located between the two fixing devices, each fixing device comprises two limiting plates and a limiting rod which are parallel to each other, the two limiting plates are both arranged on the fixing plate, the limiting rods penetrate through fixing holes formed in the two limiting plates respectively, fixing mechanisms are arranged in the limiting rods, the liquid damper comprises two pull lugs and a damper body, the two pull lugs are rotationally connected with the two limiting rods respectively, and the damper body is fixedly connected with the side walls of the two pull lugs respectively. According to the damper, displacement of a bridge can be prevented to a large extent, and the damper can be overhauled and maintained conveniently.

Description

technical field [0001] The invention relates to the technical field of bridge accessories, in particular to a bridge damper which is easy to replace. Background technique [0002] Safety is the primary consideration in bridge design, and the seismic performance of the structure needs to be considered in general bridge structure design. At present, new types of anti-seismic dampers are generally used in the design and reinforcement of large bridges at home and abroad to increase the damping of bridge structures and reduce the influence of wind, load, temperature (thermal expansion and contraction) and other factors that bridges bear during operation. [0003] Dampers are used in bridge construction mainly to play the following roles: [0004] 1. Reduce the transverse and longitudinal displacement of the bridge under loads such as earthquakes; [0005] 2. Reduce the distance of bridge expansion joints; [0006] 3. Absorb and consume the force of the pier, reducing the desig...
