![]() Lead Rubber Bearings are the most widely used technology in seismic base. A lead-rubber bearing is formed of a lead plug force- fitted into a pre-formed hole in an elastomeric bearing. It reduces seismic energy transmitted to buildings, in highly seismic prone areas. This base isolation system provides the combined features of vertical load support, horizontal flexibility, restoring force, and damping in a single unit. In this study, we present the dynamic behavior of a high-rise RC building with dynamic isolators (lead-rubber-bearing), in comparison with a traditional shear. NO.3: The realize of the sliding HDR bearing dispalcement is through the sliding friction of the ptfe plate and the corrosion resistant plate that on the top of the HDR bearing.Low friction coefficient made the HDR bearing load low friction.By sliding friction sliding to realize the functions of vibration isolation. The second type of elastomeric bearings is lead-rubber bearings (LRB). No.2:The HDR bearing is instaled on the bridge pier and bearn with sleeves and anchoring rod.The embedded steel plates are installed on the top of bearing but the bottom of the bearing have no embedded steel plates installed.The sleeves are fixed on the bottom seal layer steel plate by assembling bolt.The top embedded steel plate is installed on the top seal layer steel plate by shearing force cogged.The top embedded steel plates are designed to be welded installing with sleeves. NO.1:The HDR bearing is installed on bridge pier and beam with sleeves and anchoring ord,the embedded steel plates are installed on the top and bottom of bearing ,the sleeves are fixed on the top steel plate and bottom steel plate of the bearing by assembling bolt,the top and bottom embedded steel plates are designed to be welded installing with sleeves. Lead Rubber Bearing (LRB) is one of a type of Seismic Isolator consisting of rubber layer, steel plate, and lead core. High damping rubber bearing HDR is made of a rubber compound with high natural rubber (NR) content and has been specially designed to combine friction damping and viscous damping.As a result, it offers excellent functionality as a seismic isolation bearing, providing restorative attributes of rubber springs along with superior damping performance and high-level durability. The ISOSISM LRB (Lead Rubber Bearing) is an isolator designed using an elastomeric block (natural rubber or neoprene) reinforced with metal bands bonded by. ![]() Size Range:Lead Rubber Bearing from 400mm *400mm to 1750mm*1750mm with capacities of up to 4,000 tons are manufactured.Custom dimensions are available for special applications.ΔΆ.High Damping Rubber Bearing For Bridge and Building ![]()
