Description of Lead Core Rubber Bearing
|Lead rubber bearing is based on general laminated rubber bearings,pouring the lead into the bearing|
center, which is a seismic bearing damping performance improvement of rubber bearings. By changing
the lead core section size of the bearings, lead rubber bearing can change the effective level of equivalent
stiffness and equivalent damping ratio.
Rubber bearing that has a lead plug embedded at the centre of laminated natural rubber; where the
"laminated natural rubber" demonstrates spring capability, while the "lead plug" demonstrates damping
Types of isolation bearing according to the degree of damping points
|1.Lead rubber bearings|
LRB rubber bearing, applied to building and bridge constructions, is a practical and cost-effective choice for seismic isolation. It is composed of laminated elastomeric bearing pad, with lead in
the center of bearing. This series of bearing is suitable for 8 degrees and the earthquake intensity area
of highway and municipal bridge.
|2.High damping rubber bearings|
Its structure is the same as ordinary laminated rubber bearings, high damping rubber bearing is
improved through rubber formula, so that the rubber material damping is increased, so that the bearing's
damping ratio can reach 15-18%. This series of bearing is suitable for 9 degrees earthquak intensity
area of highway and municipal bridge.
Applications of lead core rubber bearing
The product has been successfully used in a broad range of applications which include: bridges, viaducts
, high rise buildings, stadiums and dams.
As your request, the lead rubber bearing can be manufactured in rectangular or round shapes. Custom
sizes and designs are also welcomed.
