橡胶支座产品简介
A brief introduction of rubber bearing products
橡胶支座是由多层橡胶与钢板硫化粘合而成,它有足够的竖向钢度,能将上部构造的反力可靠的传递给墩台;有良好的弹性,以适应梁端的转动,又有教大的剪切变形能力,以满足上部构造的水平位移。在板式橡胶支座表面粘复一层1.5mm-3mm厚的聚四氟乙烯板,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。
Rubber bearing is composed of multilayer rubber and steel plate vulcanization bonding, it has enough vertical stiffness can force reliable transfer to the pier superstructure; have good flexibility, in order to adapt to the rotation of the beam end, and large shear deformation ability, to meet the horizontal displacement of superstructure. After the Teflon plate 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 the rotation of the outer end of the beam, due to the low friction coefficient of PTFE plate, the beam end in PTFE sliding surface and the horizontal displacement is not restricted, especially suitable for medium and small load, large displacement bridge use.
橡胶支座特点
Characteristics of rubber bearing
橡胶支座不仅技术性能优良,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.因而在桥梁界颇受欢迎,被广泛使用。
Rubber bearings not only have excellent technical performance, but also have the characteristics of simple structure, low cost, no maintenance, easy replacement, cushioning isolation and low building height. Therefore, they are widely used in the bridge sector.

橡胶支座的适用范围
The scope of application of rubber bearing
1、普通桥梁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 common bridge rubber bearing is suitable for bridges with a span of less than 30m and small displacement. Different plane shapes are suitable for different bridge span structures, rectangular bridges are used in orthogonal bridges, and circular bearings are used for curved bridges, skew bridges and cylindrical pier bridges.
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. The application of rectangular and circular tetrafluoroplate rubber bearing is the same as that of rectangular and circular ordinary plate rubber bearing.
