Specifications

Description

Elastomeric Rubber Bridge Bearing Pad is made of multilayer Neoprene/EPDM/natural rubber and sheet steel after inlay, conglutinate, vulcanization. It has enough vertical stiffness to support vertical load, and it could deliver the pressure of superstructure to abutment. 


Laminated Elastomeric Bearing Pads

Application

Laminated elastomeric bridge bearings is finding ever increasing application in today's construction industry-as local load carrying components. It can be used for steel structures, pre-cast concrete structures, standard concrete slabs, etc. this type of bearing is particularly effective in the presence of camber and rotation causing high stress loading on the bearings.  this type of bearings provide an excellent economic solution for applications where structure movements, longitudinal, transverse and rotational are small, provide vibration isolation and are generally simple to install. 


Laminated Elastomeric Bearing Pads

Features

Our Plate Type Laminated Bridge Bearing has good elasticity to adapt to turning of beam end.

Elastomeric bearings bears and transmit vertical load & allows movement in any direction in the horizontal plane and allows rotation about any axis in horizontal plane.
3. It has bigger shearing deformation to content horizontal displacement of superstructure.
4. It has simple structure, easy installation, saving steels, low price, easy and convenient conservation and change and so on.
