Lead rubber bearing

الوصف

Lead 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, top and bottom sealing & connecting plates and lead plug inserted in the middle of the bearing.
Rubber layer andsandwich clad steel are compacted and agglutinated. When the upper structure of the rubber bearings towithstand weight and other loads, the rubber sheet ends the lateral stretch ofthe rubber, increasing the vertical stiffness. The soft rubber layer has asufficient level mobility to extend natural vibration period ofthe buildings. In addition,lead-rubber bearings into the middle bar can increase the damping ratio. Thiskind of rubber bearing, integrating support, damping, horizontal displacementand elastic reset function, is the most widely used building componentisolation. There are two types of Isolation rubber bearings, round and square.Round is the main one, which can be divided into lead-rubber bearings (LRB),natural rubber bearings (LNR) and high damping rubber bearings (HDR) of threetypes.
