ELASTOMETIC BEARING AS PER IRC: PART – II/87 Elastomeric bearings are intended for common use in road bridges. The bearing consisting of one or more internal layers of elastomer are bonded to internal sheet laminates by the process of vulcanization. The bearing caters for translation and/or rotation of the superstructure by elastic deformation CONSTRUCTION Chloroprene with low crystallization rate only are used in manufacturing of bearing. Elastomeric bearing consists of one or more internal elastomer layers. The layer of reinforcing material is integrally bonded to elastomer during vulcanization. STRUCTURE The internal layers of elastomer are of equal thickness having elastomer cover on top, bottom and slider and entire bearing is vulcanized as a single homogeneous block. The top and bottom elastomer surface directly bears on the structure faces and any displacement of bearing is safeguarded by only interface friction without any aid of adhesive or other external anchoring. No dowel holes in elastomer and laminates are provided including those filled in subsequently The minimum adhesion strength of elastomer to steel plate is 7KN/m

PTFE bearing pad, also called Teflon bearing pads, is an important material in bridge construction. The dimpled PTFE sheet bonded to the laminated bearing pad for structure friction coefficient reduction and displacement capacity improvement. It provides a sliding surface for expansion accommodation, the elasticity of the bearing pad is high enough to suit the rotation of beam end, and also the shear deformation is efficient to cope with the horizontal of the superstructure. Here are round and rectangular two main shapes of PTFE bearing pad introduced to you.Features Small friction coefficient. Larger shear capacity. Suitable for large span bridge construction. Excellent buffering and shock isolation. Withstand vertical load and rotation. APPLICATIONS It is suitable for large span, multi-span continuous beam and simply supported beam and other large displacement bridges. It can also be used as the sliding plate in continuous beam pushing construction and T beam transverse sliding. CLASSIFICATIONS PTFE bearing pad can be divided into round PTFE bearing pad and rectangular PTFE bearing pad according to different shapes. They can be used in different bridge types. The rectangular PTFE bearing pad is widely used in the straight bridge or right bridge. The round Teflon bearing pad is widely used in the skew bridge, curved bridge and other bridges.
