[Lead Rubber Bearing Isolator (LRB)] This kind product includes:Elstomeric Seismic protection isolator for bridges and buildings.It can absorb earthquake energy effectively by way of rubber’s elasticity and Lead’s restorability.Products comply with :JT/T822-2011 Lead rubber bearing isolator for highway bridge and GB 20688.3-2006 Elastomeric seimic protection isolator for buildings.
Features: ◊ Stiff and strong in vertical direction but flexible in horizontal direction.
◊ Absorb earthquake-generated force by changing the bearing’s shape.
◊ Allow the buildings to retain their original shapes and position owing to the high elastic force of rubber.
◊ Capable to adjust damping amount just by changing the number of lead plugs.
◊ Excellent vertical load capacity ranging from 5 tonf to 2000 tonf.
◊ Reduce the ground acceleration by extending the structure vibration period.
◊ High durable and elasticity of the rubber part - not suffer any damages during and after earthquake.
◊ Easy to install without a separated damper.
◊ Low maintenance.
◊ With stable bi-linear behavior shown as the above picture. This kind product includes:Elstomeric Seismic protection isolator for bridges and buildings.It can absorb earthquake energy effectively by way of rubber’s elasticity and Lead’s restorability.Products comply with JT/T822-2011 Lead rubber bearing isolator for highway bridge and GB 20688.3-2006 Elastomeric seimic protection isolator for buildings. [High Damping seismic isolation bearing] This product is comprised of high-damping rubber & plate connected with bolts.It is used under 8degrees of seismic intensity in highways and municipal bridges. Known as HDR, has very similar appearance to lead rubber bearings, but they are totally different in nature. It is composed of special rubber with excellent damping attribute,sandwiched together with layers of steel without any lead plugs. [Pot Bearings] This kind of product includes:GPZ(II), GPZ(2009), GCPZ & JPZ series pot bearing for highway bridges, and TPZB(X) series pot bearings for railway bridges. Products comply with JT/T 391 -2009 pot bearings for highway bridges and TB/T 2331-2013 pot bearings for railway bridges.
