Shock insulation support special for bridge

Abstract

The invention discloses a shock insulation support special for a bridge. The support comprises a first upper top plate, and the bottom of the first upper top plate is fixedly connected with a first upper steel plate. Through the arrangement of a first upper deformation supporting leg, a first lower deformation supporting leg, a second upper deformation supporting leg, a second lower deformation supporting leg and deformation springs, when a second shock insulation support is vibrated to generate transverse deviation, through deformation of the first upper deformation supporting leg, the firstlower deformation supporting leg, the second upper deformation supporting leg and the second lower deformation supporting leg and extrusion of the deformation springs, absorbed shock energy is conducted and released, transverse movement of the second shock insulation support is reduced, the shock insulation capacity of the shock insulation support is improved, and the service life of the shock insulation support is prolonged; an arch-shaped plate, a first sliding face, a second sliding face and the second shock insulation support are arranged, and multiple supports are matched for use, so thata bridge deck can be steered or lifted within an allowable range, pulling of the shock insulation support to the bridge deck is reduced, and the service life of the bridge is prolonged.

Description

technical field [0001] The invention relates to the technical field of shock-isolation bearings, in particular to a special seismic-isolation bearing for bridges. Background technique [0002] A bridge or a bridge is a structure built across canyons, valleys, roads, railways, rivers, other waters, or other obstacles. The purpose is to allow people, vehicles, trains or ships to pass through obstacles. The bridge can be stretched across the valley river or both sides of the strait, or raised on the ground, and cross the river or road below, so that the traffic below is unimpeded. The bridge is a kind of A large structure used to cross obstacles, to be precise, it is used to cross traffic routes such as roads, railways, waterways, etc., or other facilities such as pipelines, cables, etc., across natural obstacles such as rivers, straits, canyons, etc. or artificial obstacles such as highways The structures of highways and railway lines, while the bridge bearing is an important...

AI Technical Summary

Problems solved by technology

[0003] Although the commonly used shock-isolation bearings can play the role of shock-isolation, after excessive shocks such as earthquakes, the rubber buffer layer will move laterally and cannot be recovered. It only has the function of absorbing shocks and has no function of releasing shock energy. It needs to be replaced after excessive vibration, which is not conducive to the daily use of the bridge, and the bridge will expand and contract to a certain extent after daily use and natural changes, which will cause the bridge deck to rise or move. Seats will cause tension between the bridge and the piers, thereby accelerating the damage of the bridge deck, which is not conducive to the maintenance of the bridge
