高速桥圆形板式橡胶支座板式橡胶支座由多层天然橡胶与薄钢板镶嵌、粘合、硫化而成橡胶支座产品。它具有足够的竖向刚度以承受垂直荷载，且能将上部构造的压力可靠地传递给墩台；有良好的弹性以适应梁端的转动；有较大的剪切变形满足上部构造的水平位移；板式支座具有构造简单、安装方便、节省钢材、价格低廉、养护简便、易于更换等特点。
The plate rubber bearing is made of multilayer natural rubber and sheet steel inlaid, bonded and vulcanized to form rubber bearing products. It has enough vertical stiffness to bear vertical load, and the upper structure of the pressure can be reliably transferred to the pier have good flexibility to adapt to the rotation of the beam end meet the horizontal displacement of superstructure of large shear deformation plate bearing has the advantages of simple structure, convenient installation, saving steel, low price, easy maintenance, easy replacement.
’按形状划分：矩形、圆形、球冠圆板式、圆板坡形等。按用途可以分为：公路桥梁板式橡胶支座，铁路桥梁板式橡胶支座。聚四氟乙烯滑板橡胶支座是在普通板式支座表面粘复一层1.5mm-3mm厚的聚四氟乙烯板，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。
"According to the shape of rectangular, circular, spherical partition: circular plate, circular slope shape etc.. The utility model can be divided into a highway bridge, a plate rubber bearing, a railway bridge and a rubber bearing plate. PTFE sliding plate rubber bearing is complex PTFE layer of 1.5mm-3mm thick plate in the ordinary bearing surface, 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, due to the low friction coefficient of PTFE plate, the beam end in PTFE sliding surface, horizontal displacement is not restricted, especially suitable for medium and small load, large displacement bridge use.
板式橡胶支座能将桥梁上部的作用力可靠地传递给墩台，并同时能完成梁体结构由于制动力、温度、混凝土的收缩徐变及荷载作用等引起的水平位移及梁端的转动。该产品允许水平力为竖向的10％，允许转角不小于40，摩擦系数0.04－0.06，活动支座水平位移量50mm－250mm，分5级。荷载等级100KN－15000KN。 主要适用于公路桥梁、铁路桥梁、城市立交桥。
Rubber bearing can force the upper bridge reliably transfer to the pier, and also can complete the structure due to rotation of horizontal displacement caused by the braking force, temperature, shrinkage and creep of concrete and load and beam end. This product allows for the vertical force level of 10%, allowing the angle of not less than 40, the friction coefficient 0.040.06, bearing horizontal displacement activity 50mm250mm, 5. Load level 100KN15000KN. The utility model is mainly suitable for road bridges, railway bridges and urban overpasses.
