四氟乙烯滑板板式橡胶支座报价

Product classification

一、矩形（圆形）板式橡胶支座

First, rectangular (circular) plate rubber bearings

（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: enough vertical stiffness to bear the vertical load, good elasticity to adapt to the rotation of the end of the beam, and there is a large shear deformation to meet the horizontal displacement of the 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

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。

Features: This product is made of a thick 1.5-3mm PTFE plate bonded on the ordinary 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.

产品材质 ：橡胶、

Product material: rubber,

产品特点 ：具有构造简单、安装方便、节省钢材、价格低廉、养护简便、易于更换等特                  点。

Product features: simple structure, convenient installation, saving steel, low price, easy maintenance, easy to replace and so on.

板式橡胶支座是公路中小型桥梁中比较常用的产品，它分为普通板式橡胶支座、四氟板式橡胶支座。对于普通型桥梁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.

Plate rubber bearings are commonly used in small and medium highway bridges. They are divided into ordinary plate rubber bearing and PTFE plate rubber bearing. The common bridge bearings are suitable for bridges with spans less than 30m and small displacements. Different plane shapes are applicable to different bridge spans, rectangular supports for orthogonal bridges, circular supports for curved bridges, skew bridges and cylindrical piers
