Bridge Backing Rubber Plate
Specifications
Bridge Backing Rubber Platesuitable for bridges with span less than 30m and relative small displacement.
Bridge Backing Rubber Plate
Introduction
1) The bridge backing rubber plate can reliably transfer the counter force of top structure to the pier.
2) The bridge backing rubber plate has good flexibility to adapt to the turning of beam end.
3) The bridge backing rubber plate also has large shearing deformation performance, adapting to the horizontal dispalcement of top structure.
Structure and performance
1) The bridge backing rubber plate is made of steel plate and rubber sheets, which are vulcanized and bonded.
2) The bridge backing rubber plate has enough vertical stiffness, which can reliably transfer the counterforce of top structure to the pier.
Application range
The bridge backing rubber plate is suitable for bridges with span less than 30m and relative small displacement.
