产品划分
Product division
一、矩形（圆形）板式橡胶支座
One, rectangular (circular) plate rubber bearing
（一）性能：有足够的竖向刚度以承受垂直荷载，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。
(1) performance: there is enough vertical stiffness to withstand vertical load, so that it has good elasticity to adapt to the rotation of beam ends, and larger shear deformation to meet the horizontal displacement of upper structure.
（二）特点：本产品在桥梁建筑、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。
(two) features: This product 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 have good beneficial; isolation, live load and seismic force can reduce the impact on the building effect.
二、四氟乙烯滑板板式橡胶支座
Two, tetrafluoroethylene slide plate 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) features: This product is made of a thick 1.5-3mm polytetrafluoroethylene plate on a common plate rubber bearing. In addition to the vertical with normal rubber bearing stiffness and elastic deformation under vertical load and can adapt to the rotation of the outer end of the beam, because of low coefficient of friction between the steel plate and beam bottom tetrafluoroethylene (U = 0.03) the horizontal displacement of bridge superstructure is not restricted.
