Anti-seismic support for roads and bridges

Abstract

The invention discloses an anti-seismic support for a road bridge, belongs to the technical field of bridge buildings, and aims to solve the problems that the existing anti-seismic support lacks sufficient anti-seismic protection for transverse connection of a bridge structure, so that the bridge is easily damaged by seismic transverse waves during an earthquake; the anti-seismic support of the existing bridge is exposed to the outside for a long time, so that the anti-seismic buffer assembly is easily oxidized and damaged after being exposed to the sun and wind for a long time; the isolation cylinder and the supporting circular plate are used for packing the anti-seismic buffering assembly, the top end of the anti-seismic buffering assembly protrudes and penetrates through the isolation cylinder to be connected with the mounting plate to fix the beam body, the gyroscope supporting piece is squeezed and pushed through vibration to compress the rubber buffering block, the flexible abutting block is pushed to drive the force unloading curved rod to slide to be evenly dispersed and buffered, and distortion of vibration to the gyroscope supporting piece is overcome; the stable connection between the gyroscope supporting piece and the beam body is maintained; damage caused by earthquake vibration to a bridge is reduced, the connection stability of the bridge body during an earthquake is fully guaranteed, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an anti-seismic bearing of a road bridge. Background technique [0002] Bridges are an indispensable part of today's transportation, but in earthquakes, bridges are often severely damaged, and the damage to bridges directly affects the smoothness of lifelines in the process of earthquake relief. Therefore, how to improve the seismic capacity of bridges and reduce the damage to bridges caused by earthquakes is a very important issue. The bridge bearing is an important connecting structure between the superstructure and the substructure of the bridge, and its function is mainly to transfer the load of the superstructure to the pier. The cost of bearings accounts for only a small proportion in the overall cost of the bridge structure, but its role in the bridge structure is very large. [0003] However, the existing anti-seismic bearings mostly only focus on the shock ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide an anti-seismic bearing for road bridges, aiming at solving the above-mentioned background technology, the existing anti-seismic bearing mostly only pays attention to the shock-absorbing setting in the vertical direction, and lacks sufficient support for the horizontal connection of the bridge structure. The anti-seismic protection of the bridge structure has a limited effect on the lateral anti-seismic protection of the bridge structure, causing the problem that the bridge is easily damaged by the seismic shear wave during the earthquake, and when the anti-seismic bearing of the existing bridge is exposed for a long time, it is easy to be exposed to the wind and the sun for a long time Oxidative damage to the shock absorbing components, resulting in a decline in the earthquake resistance and protection of the shock bearing, making the bridge vulnerable to severe damage during earthquakes
