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 made up of multi-layer thin steel plate and multi-layer rubber sheet vulcanized and bonded. This product has sufficient vertical stiffness, and can reliably transmit the reaction force of the upper structure of the support to the pier. The support has good elasticity to respond to the rotation of the beam end of the bridge; and it has greater shear deformation capacity to meet the horizontal 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, simple maintenance and easy replacement. By bonding a layer 1.5mm-3mm thick PTFE plate on the surface of the plate support, the PTFE slide-plate rubber bearing can be made. Besides the vertical steel and elastic deformation, it can bear vertical load and adapt to the rotation of the beam end. Because of 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 medium and small loads and large loads. The displacement of the bridge is used.

二、四氟乙烯滑板板式橡胶支座

2. Teflon Skateboard Rubber Bearing

（一）特点：本产品是于普通板式橡胶支座上粘接一层厚1.5-3mm的聚四氟乙烯板而成。除具有普通板式橡 胶支座的竖向刚度与弹性变形，能承受垂直荷载及适应梁端转动外，因四氟乙烯与梁底不锈钢板间的低摩擦系数（μ≤0.03）可使桥梁上部构造的水平位移不受限制。

(1) Characteristics: This product is made by bonding a layer of PTFE plate 1.5-3 mm thick on the ordinary plate rubber bearing. In addition to the vertical stiffness and elastic deformation of ordinary plate rubber bearing, which can withstand vertical loads and adapt to the rotation of the beam end, the horizontal displacement of the upper structure of the bridge can not be limited due to the low friction coefficient between tetrafluoroethylene and stainless steel plate at the bottom of the beam (mu < 0.03).
