板式橡胶支座
据桥梁板式橡胶支座的结构型式分类如下
球冠圆桥梁板式橡胶支座(TCYB系列) 普通桥梁板式橡胶支座--- 矩形普通板式橡胶支座(GJZ系列) 　　圆形普通桥梁板式橡胶支座(GYZ系列) 　　板式橡胶支座 　　圆形四氟板式橡胶支座(GYZF4系列) 　　聚四氟乙烯板式橡胶支座--- 矩形四氟板式橡胶支座(GJZF4系列) 　　球冠四氟板式橡胶支座(TCYBF4系列) 
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℃
普通桥梁板式橡胶支座适用于跨度小于30m、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.
四氟桥梁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**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。
板式橡胶支座的作用及其布置支座主要有两个作用：能很好的传递桥梁上部的荷载， 调节上部结构和下部结构之间的相对位移。
板式橡胶支座主要靠的是橡胶的变形来调节平移和转动。橡胶支座是桥梁上、下部结构的连接点。其作用是将上部结构的荷载(包括恒载和活载)顺适、安全地传递到桥梁墩台上，同时要保证上部结构在支座处能自由变形(转动或移动)，以便使结构的实际受力情况与计算简图相符合。因此，对桥梁支座要正确设置，并经常注意保养维修，对其损坏部分要进行修补加固。 桥梁支座按其作用分固定支座和活动支座两类。固定支座用来固定桥梁结构在墩台上的位置，它只能转动而不能移；活动支座则可保证在温度变化、混凝土收缩和荷载作用下结构能自由转动和自由移动。
板式桥梁支座是桥跨结构的支撑部分。其作用是将桥跨结构上的荷载通过支座传递给墩台。支座的作用主要表现在一下三个方面：
Because the slab bridge support is the supporting part of the bridge span structure. Its function is to transfer the load on the bridge span structure to the abutment through the support. The role of the support is mainly reflected in the following three aspects:
1、 使反力明确地作用到墩台的*位置，并将集中反力扩散到一个足够大的面积上，以保证墩台工作的安全可靠
The reaction force is explicitly applied to the designated position of the abutment, and the concentrated reaction force is spread to a large enough area to ensure the safe and reliable operation of the abutment
2、 保证桥跨结构在支点按计算图式所规定的条件变形 
Ensure that the bridge span structure is deformed at the fulcrum according to the conditions specified in the calculation schema
3、 保证桥跨结构在墩台上的位置充分固定，不至滑落
Ensure that the position of the bridge span structure on the abutment is fully fixed and not slipped
在桥梁结构中，板式橡胶支座是桥梁上、下部结构的连接点，
In the bridge structure, the plate rubber bearing is the connection point of the upper and lower structures of the bridge.
其作用是将上部结构的荷载顺适、安全地传递到桥墩台上去，同时保证上部结构在荷载、温度变化、混凝土收缩等因素作用下的自由变形，
The function is to transfer the load of the superstructure smoothly and safely to the pier and pier, and to ensure the free deformation of the superstructure under the influence of load, temperature change and concrete shrinkage.
以便使结构的实际受力情况符合计算图式，并保护梁端、墩台帽不受损伤。
In order to make the actual force of the structure conform to the calculation pattern, and protect the beam end and the pier cap from damage.
这就要求它具有足够的竖向刚度和弹性，能将桥梁上部结构的全部荷载可靠地传递到墩台上，
This requires that it has sufficient vertical stiffness and elasticity to reliably transfer the entire load of the bridge superstructure to the abutment.
并同时承受由荷载作用引起的桥跨结构端部的水平位移、转角和变形，减轻和缓解桥墩承受的震动，适应因温度、湿度变化引起的桥跨结构胀缩。
At the same time, it is subjected to the horizontal displacement, rotation angle and deformation of the end of the bridge span caused by the load, which mitigates and alleviates the vibration of the pier and adapts to the expansion and contraction of the bridge span caused by temperature and humidity changes.
就板式橡胶支座的安装位置而言，虽然在使用中可以进行更换，但更换的成本费用、技术性以及困难性均很大，
As far as the mounting position of the plate rubber bearing is concerned, although it can be replaced in use, the cost, technicality and difficulty of replacement are large.
桥梁*部分支座可谓是*性的安装，支座寿命应该与桥梁的寿命相吻合，否则会对桥梁的使用造成不良的后果。
Most of the bearings in the bridge can be described as permanent installations, and the life of the bearings should be consistent with the life of the bridge, otherwise it will have adverse consequences for the use of the bridge.
尽管在桥梁的成本造价中支座成本仅占很小的比例，但作用远远**过其成本，为此，支座就成为桥梁建设和使用的重要材料之一。 
Although the cost of the support in the cost of the bridge is only a small proportion, but the effect far exceeds its cost, for this reason, the support has become one of the important materials for the construction and use of the bridge.
近年来在支座使用过程中，支座出现了各种各样的质量问题和质量隐患，究其原因可分为产品质量、施工质量和设计选型三方面。
In recent years, during the use of the support, various quality problems and quality hazards have appeared in the support. The reasons can be divided into three aspects: product quality, construction quality and design selection.
板式橡胶支座的产品质量、施工质量和设计选型关系到橡胶支座的使用寿命，需要生产方、施工方和设计方的紧密配合，任何一方出现问题都将严重影响橡胶支座的使用寿命。
The product quality, construction quality and design selection of the plate rubber bearing are related to the service life of the rubber bearing. The production party, the construction party and the design side need to cooperate closely. The problem of any one side will seriously affect the service life of the rubber bearing. .
