我公司生产的板式橡胶支座产品，主要包括有：普通板式支座、四氟乙烯板式支座、球冠板式橡胶支座三种产品。当在板式橡胶支座表面粘复一层1.5mm-3mm厚的聚四氟乙烯材料时,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.我公司生产的桥梁支座产品不仅技术先进、性能优良,还具有构造简单、价格低廉、无需养护 易于更换缓冲隔震、建筑高度低等特点.因而在桥梁支座颇受欢迎,被广泛使用。
Laminated rubber bearing products produced by our company, mainly include: ordinary plate bearing, tetrafluoroethylene plate bearing, spherical rubber bearing three products. When the complex of polytetrafluoroethylene 1.5mm-3mm thick layer in the laminated rubber bearing surface, can be made of PTFE sliding plate rubber support in addition to its vertical stiffness and elastic deformation under vertical load and can adapt to Liang Duan rotation, due to the low friction coefficient of PTFE plate, the beam end in PTFE surface sliding, horizontal displacement is not restricted, especially suitable for medium and small load, large bridge shift. Our company produces bridge bearing products not only advanced technology, excellent performance, but also has the advantages of simple structure, low cost, no maintenance is easy to replace the shockproof, building height is low. So the bridge supports popular and widely used.

二、板式支座的分类及表示方法
Two, the classification and representation method of plate bearing
1、 根据桥梁板式橡胶支座的结构型式分类如下:
1. According to the structure type of the bridge plate type rubber bearing, it is classified as follows:
普通板式橡胶支座---球冠圆板式橡胶支座(TCYB系列),；矩形普通板式橡胶支座(GJZ)系列；圆形普通板式橡胶支座(GYZ系列)聚四氟乙烯板式橡胶支座----圆形四氟板式橡胶支座(GYZF4系列)；矩形四氟板式橡胶
Ordinary laminated rubber bearings - spherical circular plate type rubber bearing (TCYB Series),; rectangular plate rubber bearing (GJZ) series; circular normal rubber bearing (GYZ) PTFE laminated rubber bearings - round PTFE laminated rubber bearings (GYZF4 Series); rectangular PTFE rubber plate
支座(GJZF4系列)球冠四氟板式橡胶支座(TCYBF4系列)
Bearing (GJZF4 Series) PTFE laminated rubber bearings (TCYBF4 Series)
2、 板式橡胶支座按胶种适用温度分类如下:a、氯丁橡胶: 适用温度+60℃∽-25℃ b、天然橡胶: 适用温度+60℃∽-40℃ c、三元乙丙橡胶: 适用温度+60℃∽-45℃
2, rubber plate rubber bearing according to applicable temperature classification as follows: A, neoprene: suitable temperature +60 ~ -25 C B, natural rubber: suitable temperature +60 to -40 DEG C, three EPDM: suitable temperature +60 to -45 degrees

三、板式橡胶支座适用的范围
Three, the scope of application of the plate rubber bearing
1、一般来说普通板式橡胶支座适用于跨度小于30m、适合位移量较小的桥梁.不同的平面形状适用于不同的桥跨结构,正交桥梁用矩形支座;曲线桥、斜交桥及圆柱墩桥用圆形支座.
1, generally speaking, ordinary plate rubber bearings are suitable for bridges with span less than 30m and suitable for smaller displacement. Different plane shapes are suitable for different bridge span structures, rectangular supports for orthogonal bridges, circular supports for curved bridges, skew bridges and cylindrical piers.
2、 四氟板式橡胶支座适用于大跨度、多跨连续、简支梁连续板等结构的大位移量桥梁.它还可用作连续梁顶推及T型梁横移中的滑块.矩形、圆形四氟板式橡胶支座的应用非别与矩形、圆形普通板式橡胶支座相同。
2, PTFE laminated rubber bearing is suitable for large span and multi span continuous beam, continuous plate structure of the large displacement bridge. It is also used as a continuous beam and T beam traversing the top slider in the rectangular or circular. Application of PTFE laminated rubber bearing with the same non don't rectangular or circular common plate type rubber bearing.
