阿勒泰圆形四氟板式橡胶支座

阿勒泰圆形四氟板式橡胶支座
（1）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。
(1) 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.
（2）产品用途：对于四氟乙烯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分别与矩形、圆形普通板式橡胶支座相同。
(2) product use: for 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 bearings respectively with a rectangular and circular common plate rubber bearing the same.
（3）类型：四氟橡胶滑板支座分为封闭型和简易型两种型式。对于城市桥梁及受紫外线辐射、空气污染与粉尘严重的地区,应采用封闭型,其余均可采用简易型。四氟橡胶滑板支座的型号、高度等应根据实际的位移及支座反力大小来确定。

(3) types: PTFE rubber slide bearings are divided into two types: closed type and simple type. For urban bridges and areas exposed to ultraviolet radiation, air pollution and heavy dust, closed type should be adopted, and the others can be simplified. The type and height of the PTFE rubber slide bearing should be determined according to the actual displacement and the counterforce of the support.
（4）安装：四氟橡胶滑板支座应尽量水平安装,当必需倾斜安装时,较大纵坡应≤2%。
(4) installation: PTFE rubber plate bearings should be installed horizontally, when necessary tilt installation, the maximum longitudinal slope should be less than or equal to 2%.
（5）执行标准              公路行业标准：JT/T4-2004 公路桥梁板式橡胶支座
(5) carry out standard highway industry standard: JT/T4-2004 highway bridge plate rubber bearing
