gyz300圆型四氟板式橡胶支座
圆形板式橡胶支座是由多层橡胶片与薄钢板镶嵌、粘合压制而发。有足够的竖向刚度以承压垂直荷载，能将 上部构造的反力可靠地传递给墩台，有良好的弹性，以适应梁端的转动；又有较大的剪切变形以满足上部 构造的水平位移。 圆形板式橡胶支座在桥梁建筑、水电工程、房屋抗震设施上已广泛应用，与原用的钢支座相比，有构造 简单，安装方便；节约钢材，价格低廉；养护简便，易于更换等优点，且本品建筑高度低，对桥梁设计与降低造价有益；有良好的隔震作用，可减少活载与地震力对建筑物的冲击作用。 圆形板式橡胶支座具有以下优点：

The round plate rubber bearing is made of laminated rubber sheets and thin steel plates inlaid and bonded. There are enough vertical stiffness to bearing vertical load, the upper structure of the reverse force can be reliably transferred to the pier, has good flexibility, in order to adapt to the rotation of the beam end; and to meet the horizontal displacement of superstructure of large shear deformation. Circular plate rubber bearing has been widely used in bridge construction, hydropower projects, housing seismic facilities, compared with the original steel bearing, has simple structure, convenient installation; steel saving, low price; easy maintenance, easy replacement and other advantages, and the low building height, and reduce the cost of bridge design is good; the isolation effect, can reduce the live load and seismic load on buildings impact. Round plate rubber bearings have the following advantages:
（1）圆形板式橡胶支座可以弹性吸收上部结构各方向的变形；
(1) the circular plate rubber bearing can elastically absorb the deformation of the upper structure in all directions;
（2）圆形板式橡胶支座的承压面与矩形支座相比，没有应力集中现象； （3）圆形板式橡胶支座安装方便，可以不考虑方向性；
(2) there is no stress concentration phenomenon in the bearing surface of the circular plate rubber bearing compared with the rectangular support; (3) the circular plate rubber bearing is easy to install and can not take into account the directivity;
（4）圆形板式橡胶支座比起同样作用的其他类型支座造价低，维修养护方便。
(4) compared with other bearings of the same type, the circular plate rubber bearing has low cost and convenient maintenance.
