四氟乙烯滑板橡胶支座又称为“四氟滑板式支座(GJZF4、GYZF4系列)”,它就是在板式橡胶支座的表面粘复一层1.5mm-3mm厚的聚四氟乙烯板。本产品除具有GYZ系列橡胶支座的所有功能外,由于采用了聚四氟乙烯滑板使梁底不锈钢板之间的摩擦系数变得很低,可以使桥梁上部构造的水平位移,不受桥梁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。该产品除具有球冠支座的功能外,还特别适用大位移量的桥梁。本产品1996年经衡水市技术监督局检验合格并投入生产,近年来被广泛用于本工厂,矿山,机械,电子,机械设备,厨房设备。

　　PTFE sliding bearing is also called "PTFE slide bearings (GJZF4, GYZF4), it is a complex Teflon plate 1.5mm-3mm thick layer on the surface of viscoelastic laminated rubber bearings. This product in addition to all functions with GYZ series of rubber bearings, the friction coefficient between the PTFE slide beam bottom stainless steel plate is very low, the horizontal displacement of the upper structure of the bridge, from the bridge bearing itself shear deformation limit, can satisfy the need of some bridges and large displacement. This product has the function of spherical bearings, especially for large displacement bridge. This product has been inspected and put into production in 1996 by Hengshui Technical Supervision Bureau. It has been widely used in factories, mines, machinery, electronics, machinery and kitchen equipment in recent years.

　　The product features a tetrafluoroethylene, slide plate type rubber support

　　四氟板式橡胶支座的产品特点具有构造简单、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。四氟橡胶支座的构造:在普通板式橡胶支座的表面粘贴一层聚四氟乙烯板,就构成了聚四氟乙烯橡式板胶支座,简称四氟板橡胶支座,其抗压和转动性能与普通板式橡胶支座基本相同,当然在桥梁施工实际应用时,四氟橡胶支座的整体构造并非如此简单。普通板式橡胶支座是通过支座的剪切变形来实现梁的水平位移,这种剪切变形是有一定的限值,普通板式橡胶支座不能满足位移量较大的要求。这种产品与普通板式橡胶支座不同的是:聚四氟乙烯板式橡胶支座不是通过支座的剪切变形来实现梁的水平位移,它主要通过梁底不锈钢板与摩擦系数很小的四氟板来回滑动,实现梁的水平位移,四氟板式胶支座可以适应较大跨径及多孔连续梁桥的伸缩位移。

　　PTFE rubber bearing has the characteristics of simple structure, low price, no maintenance, easy to replace, buffer isolation, low building height, so it is popular in the bridge sector, and is widely used. Structure of PTFE rubber bearings in the paste surface normal rubber bearing a layer of Teflon plate, constitute the PTFE rubber plate rubber bearing, referred to as PTFE rubber bearing, the compressive strength and rotational properties with the ordinary laminated rubber bearing is basically the same, of course, in the bridge construction practice, the overall structure is not PTFE rubber support so simple. The ordinary plate rubber bearing is to realize the horizontal displacement of the beam through the shear deformation of the bearing. The shear deformation has a certain limit, and the ordinary plate rubber bearing can not meet the requirements of large displacement. This product with the ordinary laminated rubber bearing is different: PTFE laminated rubber bearing is not through the bearing shear deformation to achieve horizontal displacement of beam, it is mainly through the PTFE plate girder bottom stainless steel plate and a very small coefficient of friction sliding back and forth, realize the horizontal displacement of beam, plate type rubber bearing can meet the PTFE expansion displacement of large span and the porous continuous girder bridge.
