Laminated High Damping Rubber Pads Bridge Elastomeric Bearing

Product DescriptionThe bearing is composed of several layers of rubber sheet and thin steel plate superimposed by pressure vulcanization, which has enough vertical stiffness to meet the vertical load, and has good elasticity to adapt to the rotation of the beam end. It has large shear deformation to meet the water of the superstructure horizontal displacement, and has a good seismic effect, can reduce the dynamic load on the upper structure and pier impact.  Mechanical Properties of RubberTechnical indexNeoprene RubberNatural RubberHardness (IRHD)60±560±5Strength Tensile (Mpa)≥17≥18Elongation at break (%)≥400≥450Brittleness temperature (ºC)≤40≤-50Constant compression permanent deformation≤15≤30Resistance to ozone aging test(test conditions,20% elongation,40ºC×96h)100ppmm25ppmmNo crackingNo crackingHot air aging test(The biggest change comparing with before aging numerical)Test conditions (ºC×h)100×7070×168Strength Tensile (%)-15-15Elongation at break(%)-40-20Variation in hardness(IRHD)0,+10-5,+10Strength of rubber and steel Peel adhesive (KN/m)>10>10Strength of four fluorine plate and rubber (KN/m)>7>7Features of rubber bridge bearing:(1) Quality materials including natural rubber, neoprene complying with AASHTO standards.(2) Allow for expansions and contractions of precast steel structure of bridges.(3) Capable to control load distribution, meanwhile accommodate thermal and end-beam rotational movements.(4) Vibration, sounds and shocks isolation.(5) Avoid excessive load eccentricity and edge compression.(6) Simple but robust structure.(7) Lower price than laminated elastomeric bearing.(8) High cost effectiveness.(9) Minimal maintenance is needed  Table 1.
