Laminated Elastomeric Bearing Pads For Bridges

The elastomeric type bearing is finding ever increasing application in today s construction industry.
Laminated elastomeric bearing pads for bridges. Bridge design specifications section 14 should be considered the preferred type of bearing for all structures. Plain elastomeric bearing pads can be used for small bridges in which the vertical loads translations and rotations are relatively small. For applications where horizontal displacements exceed 2 inches 50mm sliding elastomeric bearing assemblies may provide an economical solution. Rectangular laminated bearing pad one of most popular type in laminated bearing pad is made of chloroprene rubber cr or natural rubber nr the chloroprene rubber laminated bearing pad is suitable for environments where the temperature ranges from 25 c to 60 c.
Rectangular laminated bearing pad excellent shear deformation elasticity. For applications in highway construction most states and agencies require 100 pure virgin polymer to. Reinforced elastomeric bearing pads. Reinforced elastomeric bearing pads designed in accordance with.
The elastomeric compound used in the construction of a bearing shall contain only either natural rubber or chloroprene rubber as the raw polymer. The typical hinge or abutment configuration using many small elastomeric bearing pads has proved highly reliable and. Laminated elastomeric bearing pad one type of reinforced elastomeric bearings is made of multi layer rubber and reinforced with steel plate through sulfuration and adhesion compared with non reinforced elastomeric bearing it has sufficient vertical rigidity which can reliably transfer the concentrated down loads and impact loads of the superstructure to both ends of the pier. Our elastomeric bearings pads are manufactured with the highest quality neoprene.
Internal steel laminates shall be of rolled mild steel. The addition of a low friction sliding surface allows a standard laminated elastomeric bearing device to accommodate unlimited horizontal displacement without increasing the height of the bearing assembly. Although used extensively in bridges bearing pads are being specified in a wide variety of applications where flexible structural support and or vibration isolation is required. Bridge and its supporting structure.
Plain bearing pads shall be molded individually or cut from previously molded strips or slabs or extruded and cut to length. Brp elastomeric bearings pads are designed for use in bridge and building construction elastomeric bearings pads are commonly used under pre cast concrete beams steel beams and in various other support points. Elastomeric laminated bearings elastomeric laminated bearings elb s are made from high purity elastomers which encapsulate layered internal steel reinforcing plates. Designed for use in bridge and building construction under pre cast concrete beams steel beam supports and other support points.
As we all know the bearing pad can be divided into elastomeric bearing pad and laminated rubber bearing pad according to different inner structure.
