圆形橡胶支座是板式支座的一种,它与矩形板式橡胶支座特性基本相同，只是其平面形状为圆形，具有剪切变形的同等性，克服了矩形橡胶支座某些遇应力集中的现象，可将上部构造复杂变形和转动经过支座橡胶层的弹性变形来完成。在圆板橡胶支座上用特殊方法粘复一层聚四氟乙烯板（F4），使梁底不锈钢板与F4板之间的自由滑动，完成上部结构较大的位移量,它除了具有矩形橡胶支座的功能外，因其平面圆形在安装时可不考虑其方向性，在弯桥、斜交桥、曲线桥上使用，其优点更为明显。

The circular rubber bearing is a bearing plate, and rectangular plate rubber bearing characteristics are basically the same, but the plane shape is round, with the same shear deformation, overcome the rectangular rubber bearing in some stress concentration phenomenon, can be achieved through deformation and rotation bearing rubber layer elastic deformation of complex superstructure. In the plate rubber bearing with special complex method of sticking a layer of Teflon plate (F4), the free sliding between the stainless steel plate and F4 plate beam bottom, complete displacement of upper structure, it has a rectangular rubber bearing function, because of its flat circle in the installation can not consider the direction. In the use of curved bridge, skew bridge, curved bridge, its advantage is more obvious.

圆形板式橡胶支座由多层橡胶片与薄钢板硫化、粘合而成，它有足够的竖向刚度，能将上部构造的反力可靠的传递给墩台，有良好的弹性，以适应梁端的转动；又有较大的剪切变形能力，以满上部构造的水平位移。在上述的圆形板式橡胶支座表面粘复一层1.5mm-3mm的聚四氟乙烯圆形板式橡胶支座，制造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磨擦系数，可使梁端在四氟板表面向内滑动，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。

Circular plate rubber bearing is composed of multilayer rubber sheets and thin plate vulcanization, bonding, it has enough vertical stiffness, can force reliable transfer to the pier top structure, good flexibility, in order to adapt to the rotation of the beam end; and a larger deformation, the horizontal displacement of the full structure. On the surface of the circular plate rubber bearing, a 1.5mm-3mm PTFE plate rubber bearing is bonded to form a polytetrafluoroethylene sliding plate rubber bearing. In addition to its vertical stiffness and elastic deformation under vertical load and can adapt to the rotation of the outer end of the beam, because of low friction coefficient of PTFE plate, the beam end in inward PTFE sliding surface, the horizontal displacement is not restricted; especially suitable for medium and small load, large displacement of the bridge.
