Rubber bridge expansion joints, is also called rubber expansion joint. It is a device relative movement between two parts of a structure. It is made mainly of natural / neoprene rubber and use steel plate as skeleton for reinforcement.
It is designed and manufactured using the principle of low shear modulus of rubber. It can accommodate expansion displacement by shear deformation of rubber. It featured by low lateral resistance of expansion and compression. And it benefit to bridge structure.
Structure:
Rubber bridge expansion joints are consisted of rubber, reinforce steel plate, ranura, sealing block, fitting portion, nut plate, kidney-shaped cap, nuts and bolt.Expansion range:
30mm--330mm
