Bridge rubber support

Abstract

The invention discloses a bridge rubber support which comprises a bottom plate, a top plate and a rubber block arranged between the bottom plate and the top plate, wherein the bottom plate and the top plate are both round steel plates; a plurality of circumferentially distributed mounting holes are formed in the edge of the upper side of the bottom plate; four arc-shaped blocks are arranged on the bottom plate, and are symmetrically arranged around the center of the bottom plate; concave surfaces of the arc-shaped blocks are arranged inwards; strengthening blocks are arranged on the outer side of the arc-shaped blocks; one side of each strengthening block is propped against a convex surface of the corresponding arc-shaped block; the lower ends of the strengthening blocks are fixedly connected with the bottom plate; a limit block is vertically arranged in the middle of the bottom plate; a limit hole corresponding to the limit block is formed in the middle of the bottom surface of the rubber block; four damping and buffering mechanisms are arranged among the rubber block and the arc-shaped blocks; the four arc-shaped blocks form a circular groove. The damping and buffering mechanisms are arranged among the rubber block and the arc-shaped blocks to be taken as a secondary buffering mechanism of the rubber support, so that the loading capacity of the rubber block is effectively improved.

Description

technical field [0001] The invention relates to the technical field of rubber bearings, in particular to a bridge rubber bearing. Background technique [0002] The bridge rubber bearing is erected on the pier and is an important structural component connecting the upper structure and the lower structure of the bridge. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the upper structure of the bridge to the lower structure of the bridge, thereby improving the bridge. seismic performance. Most of the traditional rubber bearings use pot-type rubber bearings. This kind of rubber bearing consumes a lot of steel and is relatively heavy. It takes time and effort to install, and there is no additional buffer mechanism inside the pot-type rubber bearing. When the pressure on the rubber block inside the body is too large or the sway of the bridge body is too large, the lateral deformation of the rubber block will easily exceed its beari...

Problems solved by technology

Most of the traditional rubber bearings use pot-type rubber bearings. This kind of rubber bearing consumes a lot of steel and is relatively heavy. It takes time and effort to install, and there is no additional buffer mechanism inside the basin-type rubber bearing. When the pressure on the rubber block inside the body is too large or the sway of the bridge body is too large, the lateral deformation of the rubber block will easily exceed its tolerance range, resulting in its damage and even the collapse of the building. If the basin wall is directly used to hold the rubber block to prevent its deformation , the buffering time and distance are very short, which will inevitably weaken the buffering and shock-absorbing capacity of the rubber bearing, and then affect the seismic capacity of the bridge. At the same time, it also caused a huge impact on the rubber bearing itself, affecting the stability of its structure
