Plate is circular steel plate, is provided with multiple installing hole in circumferential array at the upper edge of described base plate, and described base plate is provided with
Four pieces of block arcs, and four pieces of block arcs are symmetrical set around the center of base plate, described block arc concave surface is arranged inwardly,
And the outside of block arc is provided with boss, the side of described boss offsets with the convex surface of block arc, and boss lower end
Fixing with base plate and be connected, the middle part of described base plate is vertically provided with limited block, is provided with and limited block in the middle part of the bottom surface of described block rubber
The spacing hole being correspondingly arranged, is provided with four damping, buffering mechanisms, and four damping, bufferings between described block rubber and block arc
Mechanism surrounds a circular trough, and described damping, buffering mechanism includes the curved plate that polylith is arranged, and curved plate in stacking
Length value and width value successively decrease the most successively, and described one end of damping, buffering mechanism offsets with the sidewall of block arc.
Preferably, described base plate, block arc and boss are one-body molded.
Preferably, the bottom surface of described top board is provided with multiple tapered protrusion being distributed in array.
Preferably, the height of described damping, buffering mechanism is less than the height of block arc, and the edge of described top board is positioned at arc
The surface of shape block.
Preferably, described damping, buffering mechanism includes four pieces of curved plates arranged in stacking, and near the one of block rubber
The back side of block curved plate is vertically provided with a gag lever post, and the through hole on its excess-three block curved plate is run through also in one end of gag lever post
It is plugged in the stopper slot on block arc.
Compared with prior art, the invention have the benefit that the basin with block arc replacement tradition pot rubber bearing
Body portion, while ensureing structural strength, decreases the usage amount of steel；By arranging between block rubber and block arc
Damping, buffering mechanism as the level 2 buffering mechanism of rubber support, buffer time and distance when not only extending bridge swing, and
And indirectly improve the load capacity of rubber support, it is to avoid block rubber is damaged when by excessive pressure, then causes bridge
Shock resistance is affected；Additionally, the damping, buffering mechanism in the present invention can individually mount and dismount, also can be according to bridge
The number needing the change in-house curved plate of damping, buffering of joist support weight and thickness, not only facilitate the mistake installed and safeguard
Journey, and improve the scope of application of this rubber support, construction and construction for bridge bring great convenience.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
With reference to Fig. 1-4, a kind of bridge rubber bearing, including base plate 1, top board 2 and the block rubber being disposed there between
3, base plate 1 and top board 2 are circular steel plate, are provided with multiple installing hole 8 in circumferential array, top board 2 at the upper edge of base plate 1
Bottom surface be provided with multiple in array distribution tapered protrusion, after tapered protrusion is absorbed in block rubber 3 inside, top board 2 can be avoided
