Introduction and Application of Rubber Beams
Introduction and Application of Rubber Beams 1. Introduction The rubber beam is vulcanized and bonded by a multi-layer rubber sheet and a thin steel plate. It has sufficient vertical steel to reliably transmit the reaction force of the upper structure to the abutment; it has good elasticity to adapt to the beam end. Rotation, and greater shear deformation ability to meet the horizontal displacement of the upper structure. In addition to the PTFE plate on the surface of the above-mentioned plate rubber bearing, it can be made into a PTFE sliding plate rubber bearing. In addition to vertical steel and elastic deformation, it can withstand vertical loads and adapt to beam end rotation. In addition, due to the low friction coefficient of the PTFE plate, the beam end can slide freely on the surface of the PTFE plate, and the horizontal displacement is not limited. It is especially suitable for bridges with medium and small loads and large displacem...
