Building isolation rubber bearings

Building isolation rubber bearings:
Rubber bearings are a common rubber bearing product made by vulcanizing and bonding multiple layers of thin steel plates and multiple layers of rubber sheets. This product has sufficient vertical stiffness and can reliably transmit the reaction force of the upper structure of the bearing to the pier. The bearing has good elasticity to cope with the rotation of the beam end of the bridge; It also has a large shear deformation capacity to meet the horizontal displacement of the upper structure.
Features:
It has the characteristics of simple structure, easy installation, steel saving, low price, easy maintenance, and easy replacement. By sticking a layer of 1.5mm-3mm thick polytetrafluoroethylene plate on the surface of the plate support, a polytetrafluoroethylene sliding plate rubber support can be made. In addition to vertical stiffness and elastic deformation, it can withstand vertical loads and adapt to beam end rotation. Due to the low friction coefficient of the polytetrafluoroethylene plate, the beam end can slide freely on the surface of the plate, and the horizontal displacement is not limited. It is particularly suitable for bridges with medium to small loads and large displacement.
