Rubber Bridge Expansion Joints


Rubber bridge expansion joints made of rubber, steel plate and angle iron are designed to strengthen the bearing capacity of bridges.

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.
Rubber bridge expansion joints made of prime-quality rubber are anti-aging and have a long service life. Being wear-resistant, this product can withstand reiteration function of vehicle load. During installation, bolt holes on the bottom and each junction are filled with adhesion agent which makes the whole rubber bridge expansion joints be highly water-resistant.

Rubber bridge expansion joints for movements of up to 60 mm apply to normal bridges. Compared with expressway, rubber bridge expansion joints are more suitable for being installed on the flyovers. They are also good choices for building new bridges.
