Energy consuming support for bridge

Abstract

The invention relates to an energy consuming support for a bridge and belongs to the technical field of bridge safety. The energy consuming support for the bridge comprises an upper connecting plate,a lower connecting plate and an energy consuming component, wherein the upper connecting plate and the lower connecting plate are arranged in parallel; the energy consuming component comprises a waist-shaped energy consuming steel ring; a first connecting plane and a second connecting plane of the energy consuming steel ring are correspondingly and fixedly connected with the upper connecting plateand the lower connecting plate; the interior of the energy consuming steel ring is filled with rubber; and the rubber is fixedly connected with the energy consuming steel ring. According to the energy consuming support for the bridge, by combining the energy consuming steel ring with excellent energy consuming ability and the rubber with good deformation ability, the energy consuming support possesses larger deformation amount so that the anti-seismic property of the bridge is improved.

Description

technical field [0001] The invention belongs to the technical field of bridge safety, and relates to an energy-dissipating support for a bridge. Background technique [0002] my country is an earthquake-prone country. Many important bridges are located in high-intensity earthquake areas, and the bridges are in the throat of lifelines, which play an extremely important role in earthquake relief. [0003] The anti-seismic technology of bridges has always been the focus of engineers' research. Among them, anti-seismic technology is one of the main concerns. The method of anti-seismic is to install anti-vibration bearings with energy dissipation capacity between the upper structure and the lower structure. . When the bridge structure encounters an earthquake, the shock-absorbing and isolating bearing can dissipate the seismic energy, thereby protecting the main body of the structure from damage. [0004] At present, commonly used vibration-absorbing and isolating bearings incl...

AI Technical Summary

Problems solved by technology

[0005] The shock absorption and isolation performance of the lead rubber bearing is stable, but there is also a risk of environmental pollution

The energy dissipation capacity of the high-damping rubber bearing is greatly affected by the ambient temperature, and the performance is not stable

Friction pendulum bearings are mainly used on large or extra-large bridges due to their high cost, and are not practical for medium and small bridges with large quantities and wide areas.
