Overview of Plate Rubber Bearing Products:
橡胶支座是由多层薄钢板与多层橡胶片硫化粘合而成的一种普通橡胶支座产品，这种产品具有足够的竖向刚度，能够将支座上部构造的反力可靠的传递给墩台，支座具有良好的弹性，以应对桥梁的梁端的转动；又有较大的剪切变形能力，以满足上部构造的水平位移。
Rubber bearing is a common rubber bearing product, which is madeup of multi-layer thin steel plate and multi-layer rubber sheetvulcanized and bonded. This product has sufficient verticalstiffness, and can reliably transmit the reaction force of theupper structure of the support to the pier. The support has goodelasticity to respond to the rotation of the beam end of thebridge; and it has greater shear deformation capacity to meet thehorizontal displacement of the upper structure. 。
板式橡胶支座特点:
Characteristics of plate rubber bearing:
具有构造简单、安装方便、节省钢材、价格低廉、养护简便、易于更换等特点。在板式支座表面粘复一层1.5mm-3mm厚的聚四氟乙烯板,就能制作成聚四氟乙烯滑板式橡胶支座它除了竖向钢度与弹性变形，能承受垂直荷载及适应梁端转动外,因聚四氟乙烯板的低摩擦系数，可使梁端在四氟板表面自由滑动，水平位移不受限制，特别适宜中、小荷载,大位移量的桥梁使用。
The utility model has the advantages of simple structure,convenient installation, steel saving, low price, simplemaintenance and easy replacement. By bonding a layer 1.5mm-3mmthick PTFE plate on the surface of the plate support, the PTFEslide-plate rubber bearing can be made. Besides the vertical steeland elastic deformation, it can bear vertical load and adapt to therotation of the beam end. Because of the low friction coefficientof the PTFE plate, the beam end can slide freely on the surface ofthe PTFE plate, and the horizontal displacement is not limited. Itis especially suitable for medium and small loads and large loads.The displacement of the bridge is used.
