Rubber Expansion Joints

Rubber bridge expansion joints are mainly made of rubber, steel plate, and angle iron. Rubber bridge expansion joints for movements of up to 60 mm apply to normal bridges. Compared with expressways, rubber bridge expansion joints are more suitable for being installed on flyovers. They are also good choices for building new 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 the 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.

Features and benefits:

  • Low shear module of rubber
  • Reliable installation
  • Smooth driving
  • Light in weight
  • Excellent waterproof function
  • Applications with a maximum movement of 260mm
