Elastomeric neoprene bridge bearing pads
Elastomeric bearing pad is plate / pad type vulcanized rubber products for bridge and building construction. It is reinforced with inner steel plates.
It is in an important place of above and under structure joints. It is applied to bridge beam ends, for shock absorption and comfortable driving, which can ensure the safety and lengthen the service time of bridges construction and building.It is widely used in kinds of bridges in municipal engineering, highway bridge construction etc
Structure
The laminated rubber bearing pad can be divided into standard laminated bearing pad and sliding laminated bearing pad.
