桥梁板式橡胶支座的结构及性能
Structure and performance of bridge plate rubber bearing
桥梁板式橡胶支座由多层橡胶片与薄钢板硫化，粘合、硫化而成的一种桥梁橡胶支座产品，它有足够 的竖向刚度，能将上部构造的反力可靠地传递给墩台，具有良好的弹性，以适应两端的转动，同时又有较大的剪切变形能力，以满足上部构造的水平位移
Bridge plate rubber support by multilayer rubber sheets and thin plate vulcanization, adhesion, curing and into a bridge rubber bearing products, it has enough vertical stiffness, the upper structure of the reverse force can be reliably transferred to the pier, with good flexibility, in order to adapt to the ends of the rotation, and a larger shear the deformation ability, to meet the horizontal displacement of superstructure
在上述的桥梁板式橡胶表面粘覆一层厚1.5mm—3mm的聚四氟乙烯板，就制作成聚四氟乙烯板式橡胶支座，它除了具有竖向刚度与弹性变形，能承受垂直荷载及适应两端转动外，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。
In the bridge plate rubber surface is adhered to the Teflon plate of a thick layer of 1.5mm - 3mm, is made of PTFE laminated rubber bearings, it has the vertical stiffness and elastic deformation, can withstand the vertical load and adapt to the rotation of the outer ends, because of the low friction coefficient of PTFE plate, the beam end in PTFE the surface of the plate to slide freely, the horizontal displacement is not restricted, especially suitable for medium and small load, large displacement bridge use.
桥梁板式橡胶支座的分类及表示方法
Classification and representation method of bridge plate rubber 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:

Polytetrafluoroethylene plate rubber bearing - Rectangular tetrafluoroplate rubber bearing (GJZF4 Series)
球冠四氟板式橡胶支座(TCYBF4系列)
PTFE laminated rubber bearings (TCYBF4 Series)
2、 板式橡胶支座按胶种适用温度分类如下:
2. The panel type rubber bearing is classified according to the suitable temperature of the adhesive.
a、氯丁橡胶: 适用温度+60℃∽-25℃
A, neoprene: suitable temperature +60 to -25 degrees
b、天然橡胶: 适用温度+60℃∽-40℃
B, natural rubber: suitable temperature +60 to -40 degrees
c、三元乙丙橡胶: 适用温度+60℃∽-45℃
C, three EPDM: suitable temperature +60 to -45 degrees
桥梁板式橡胶支座的适用范围
The scope of application of bridge plate rubber bearing
1、 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.
1, the ordinary bridge plate rubber bearing is suitable for bridges with a span less than 30m and a 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 bridge plate rubber support 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 non rectangular or circular ordinary laminated rubber bearing the same.
