四氟乙烯滑板式橡胶支座就是在普通板式橡胶支座的表面粘复一层1.5mm-3mm厚的聚四氟乙烯板,就能制作成橡胶支座,又称之为：四氟滑板式支座(GJZF4四氟乙烯滑板式橡胶支座、GYZF4四氟乙烯滑板式橡胶支座系列)。除具有GYZ系列橡胶支座的所有功能外，聚四氟乙烯板（F4板）与梁底不锈钢板之间的低摩擦系数，使上部构造的水平位移，不受支座本身剪切变形量的限制，能满足一些桥梁的大位移量需要。该板式橡胶支座除具有球冠橡胶支座的功能外，还特别适用大位移量的桥梁。广泛用于工厂，矿山，机械，电子，机械设备，厨房设备。
四氟板式橡胶支座不仅技术先进、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。
四氟板式橡胶支座使用范围
a.作活动支座使用：主要用于跨度〉30米的大跨度桥梁简支梁连续板桥、多跨连续梁桥。
b.作为滑块使用连续梁顶推、T型梁横移、大型设备滑移。
四氟板式橡胶支座选用和安装
1、选择四氟滑板式橡胶支座时，其支座承载力偏差范围应控制在士10％。GJZF4四氟乙烯滑板式橡胶支座、GYZF4四氟乙烯滑板式橡胶支座应水平安装，并应设置上、下钢板。四氟板与不锈钢板间应放5201-2硅脂润滑油。安装后一定要设置防尘罩。
2、板式橡胶支座计算承载力时，应按有效面积（钢板面积）计算；计算水平剪应力时，应按支座平面毛面积（公称面积）计算。
3、四氟滑板式橡胶支座安装时应以短边尺寸顺桥向放置，具体安装及注意事项请在购买后直接咨询厂家。

PTFE sliding plate rubber support is Teflon plate 1.5mm-3mm thick layer on the surface of ordinary glued laminated rubber bearing, can be made into rubber bearing, also known as: PTFE slide bearings (GJZF4 PTFE sliding plate rubber support and GYZF4 tetrafluoroethylene sliding plate rubber bearing series). In addition to all functions with GYZ series rubber, PTFE plate (F4 plate) and low coefficient of friction between the beam bottom stainless steel plate, the horizontal displacement of superstructure, the support shear deformation limit, it can meet the needs of large displacement bridge. The rubber bearing has a spherical rubber bearing function, especially for large displacement bridge. Widely used in factories, mines, machinery, electronics, machinery and equipment, kitchen equipment.
PTFE laminated rubber bearing not only advanced technology, excellent performance, but also has the advantages of simple structure, low cost, no maintenance, easy replacement of shockproof, building height is low. So in the bridge area is very popular, widely used.

Scope of use of PTFE rubber bearing
A. for movable support: mainly used for span 30 meters large span bridges, simple supported beam continuous slab bridge, multi span continuous beam bridge.
B. is used as slide block, using continuous beam pushing, T beam moving horizontally and large equipment slipping.
Selection and installation of PTFE plate rubber bearing
1, the selection of PTFE slide type rubber bearings, the bearing capacity deviation range should be controlled at Shi 10%. GJZF4 PTFE sliding plate rubber support and GYZF4 PTFE sliding plate rubber support should be installed horizontally, and should set the upper and lower plate. PTFE plate and stainless steel plate should be placed between the 5201-2 grease lubricating oil. Be sure to set up the dust cover after installation.
2, the calculation of bearing capacity of plate type rubber bearings should be calculated according to the effective area (steel plate area). When calculating the horizontal shear stress, the gross area (nominal area) of the supporting plane should be calculated.
3, PTFE slide type rubber bearing installation should be short edge size along the bridge placed, specific installation and matters needing attention, please after the purchase of direct consultation manufacturers.
