Problems solved by technology

However, it will cause the change and uplift of the height of the beam body, which will affect the smoothness of the railway bridge track on the one hand and affect the safety of driving; on the other hand, it will generate additional internal stress and affect the overall mechanical structure of the bridge, especially in simply supported railway beams. It is not suitable to use on long-span continuous beams
At the same time, the spherical radius is large, the structure size is large, and the cost is high

Abstract

A self-resetting friction-damping shock absorption bearing and a shock absorption bridge. The shock absorption bearing includes a first bearing plate, a second bearing plate, a support panel, a friction member, a first shock absorption member, and a second shock absorption member. The first bearing plate is connected to the support panel, both ends of the friction member are respectively connected to the second bearing plate and one end of the support panel away from the first bearing plate, and the friction member can slide relative to the support panel and the second bearing plate. A shock absorption bridge including a self-resetting friction-damping shock absorption bearing is also provided.

Description

technical field [0001] The invention relates to the technical field of shock absorption, in particular to a self-resetting friction damping shock absorbing support and a shock absorbing bridge. Background technique [0002] With the development of modern high-speed railways, the proportion of bridges in railway routes is getting higher and higher. When an earthquake disaster occurs, the bridge is the most vulnerable part; the use of bridge shock-absorbing and isolating bearing devices is a feasible method of shock absorption, and it is also a relatively mature and widely used anti-seismic technology. At present, the main anti-seismic bearing devices in China include anti-seismic basin rubber fixed bearing, lead core rubber bearing and friction pendulum type seismic isolation bearing, etc. [0003] The anti-seismic pot-type rubber fixed bearing has good damping properties, and can isolate the upper and lower seismic movements through shear deformation. It has the advantages ...
