Abstract

A bridge anti-seismic support comprises a beam bottom embedded steel plate and a padstone top surface steel plate, a support upper steel plate is fixedly connected with the beam bottom embedded steel plate through an upper anchor rod, a support lower steel plate is fixedly connected with the padstone top surface steel plate through a lower anchor rod, the support upper steel plate is located on the inner side of the support lower steel plate, and a cavity is defined by the support upper steel plate. The cavity is filled with the transversely-placed middle buffering energy-absorbing block, the support lower steel plate and the support upper steel plate are oppositely arranged in the opposite directions, the side face of the support lower steel plate and the side face of the support upper steel plate are oppositely arranged, and the space between the side face of the support upper steel plate and the side face of the support lower steel plate is vertically filled with the peripheral buffering energy-absorbing block. The buffer energy-absorbing block can effectively prevent rigid damage of seismic waves to the bridge. The bridge anti-seismic support guarantees the stability of a bridge, is safe, reliable, high in buffering capacity and large in absorbed energy, has the advantages of being easy to manufacture and convenient to install, and has high practicability.

Description

technical field [0001] The invention belongs to the field of bridge supports, in particular to a bridge anti-seismic support. Background technique [0002] The bridge bearing is an important part of the bridge structure. In addition to supporting the bridge, it also has the functions of shock absorption and displacement resistance when an earthquake occurs. The bridge bearing plays a very important role in the stability and safety of the bridge; At present, the commonly used bridge bearings are mostly natural rubber bearings, lead rubber bearings and friction pendulum bearings. These bearings have small buffering capacity and small energy absorption during earthquakes. The collapse of the middle part of the bridge and the phenomenon of falling from the pier, especially for strong earthquakes and long-span bridges, this phenomenon is particularly obvious; the reason is that the ground longitudinal wave and shear wave pier action during the earthquake, which in turn leads to t...
