Rubber bridge expansion joints are mainly made of rubber, steel plate and angle iron. Steel plates are set in the rubber bridge expansion to strengthen the bearing capacity and they can slide freely along the angle iron to meet the expansion deformation of main grid.
Because of the excellent sealability and shock-absorbing effect of rubber, rubber bridge expansion joints do well in proofing water and reducing noise. The elasticity of rubber plates and its shear deformation in the telescopic channel helps the whole device to realize telescopic motion.
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.
