The lower surface of rust steel plate is in contact；The upper and lower surface of intermediate liner plate opens up fluted, and the setting of the lower part of polyfluortetraethylene plate exists
In the groove of intermediate liner plate upper surface, the top of rubber is arranged in the groove of intermediate liner plate lower surface；The inside of rubber is embedded
There are spring couplingplate and several spaced middle steel plates, spring couplingplate is coaxial with rubber, and middle steel plate is arranged in spring band
The inner cavity of circle.
There is deformation gap between the upper surface and stainless steel plate of intermediate liner plate upper surface groove outer rim.
The top of polyfluortetraethylene plate is arranged with rubber seal, and rubber seal is filled in the deformation gap.
It is clearance fit between groove and polyfluortetraethylene plate that intermediate liner plate upper surface opens up.
It is clearance fit between groove and rubber that intermediate liner plate lower surface opens up.
The lower surface of the stainless steel plate and bearing steel plate is bonded by epoxy resin.
Further include dust cover, dust cover is coated on the periphery of stainless steel plate, polyfluortetraethylene plate, intermediate liner plate and rubber,
The top of dust cover is tightly connected with stainless steel plate, and lower part is connect with rubber seal.
Compared with prior art, the utility model has the advantages that：
The stainless steel plate of the utility model highway bridge bearing is fixedly connected with the lower surface of bearing steel plate, polytetrafluoroethylene (PTFE)
The upper surface of plate is in contact with the lower surface of stainless steel plate, therefore can pass through the cunning between polyfluortetraethylene plate and stainless steel plate
It is dynamic to increase displacement；
The upper and lower surface of intermediate liner plate opens up fluted, and the lower part of polyfluortetraethylene plate is arranged in intermediate liner plate upper surface
Groove in, the top of rubber is arranged in the groove of intermediate liner plate lower surface, and therefore, the intermediate liner plate of the structure can avoid
In the upper surface of rubber, fluting makes rubber generates to weaken to destroy to place polyfluortetraethylene plate；
The inside of rubber is embedded with spring couplingplate and several spaced middle steel plates, and spring couplingplate is same with rubber
Axis, middle steel plate are arranged in the inner cavity of spring couplingplate, and spring couplingplate and middle steel plate can constrain inner rubber material and laterally become
Shape avoids outside from crack bulge situation occur, increases rubber support bearing capacity, meanwhile, its anti-seismic performance can be improved；
And the height of entire bearing can be adjusted using intermediate liner plate so that bearing replacement is convenient.
