Funcional Rubber Bearing (FRB)
A Stopper is formed on the end plate to prevent the peeling of coating in order to resolve the elastic pad peeling, and the end plate is prevented from being exposed even if the peeling occurs,
thereby improving the durability of bearing and increasing the life of bridge.
The core anchor can be used to reduce the size of existing bolt, and the socket diameter can be increased to control horizontal force.
It has the advantage of minimizing the number of bolts used.
1. Features
• No lifting(rollover) or slip(roll-out) occurs, maximizing the seismic effect
• Rubber pads do not slip and require no follow-up process and maintenance such as jack-up and restoration
• Eccentricity of the bottom structure is prevented because there is no sliding of rubber pad.
• Upper and lower steel paltes are integrated with rubber pads, ensuring excellnet application to steel bridges and long bridges
• Improvement in the performance and durability of bearing
