gyzf4四氟乙烯滑板橡胶支座现货供应

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经衡水市技术监督局检验合格并投入生产，近来被广泛用于本工厂，矿山，机械，电子，机械设备，厨房设备。

一、四氟乙烯滑板式橡胶支座的产品特点

the product features a tetrafluoroethylene, slide plate typerubber 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。

the products of ptfe rubber bearing have the characteristics ofsimple structure, low cost, no maintenance, easy replacement,buffer isolation and low building height, so they are popular andwidely used in bridge circles. structure of ptfe rubber bearings inthe paste surface normal rubber bearing a layer of teflon plate,constitute the ptfe rubber plate rubber bearing, referred to asptfe rubber bearing, the compressive strength and rotationalproperties with the ordinary laminated rubber bearing is basicallythe same, of course, in the bridge construction practice, theoverall structure is not ptfe rubber support so simple. theordinary plate rubber bearing realizes the horizontal displacementof the beam through the shear deformation of the bearing. thisshear deformation has a certain limit, and the ordinary platerubber bearing can not meet the re of large displacement.this product with the ordinary laminated rubber bearing isdifferent: ptfe laminated rubber bearing is not through the bearingshear deformation to achieve horizontal displacement of beam, it ismainly through the ptfe plate girder bottom stainless steel plateand a very small coefficient of friction sliding back and forth,realize the horizontal displacement of beam, plate type rubberbearing can meet the ptfe expansion displacement of large span andthe porous continuous girder bridge.

二、四氟板式橡胶支座使用范围

two, ptfe plate rubber bearings range of use

a.作活动支谇使用：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。

a. use: mainly used to support the activities of large spanbridge beam span of 30 meters. the continuous slab bridge, multispan continuous beam bridge.

b.作为滑块块使用连续梁顶推、t型梁横移、大型设备滑移。四氟板式橡胶支座的整体构造由梁底钢板、不锈钢板、四氟板式橡胶支座与支座垫石等组成。

b. is used as slide block, using continuous beam pushing, t beammoving horizontally, large e sliding. the whole structureof the ptfe rubber bearing consists of the steel plate at thebottom of the beam, the stainless steel plate, the ptfe platerubber bearing and the bearing pad stone.

梁底钢板：又称支座上钢板，位于梁端支点处，可通过预埋或粘贴形式就位，西小江大桥上钢板与梁底之间采用环氧树脂粘贴固定。钢板厚度为18mm，下面有深1.5mm的宽槽用以嵌放不锈钢板。宽槽制成楔形，在梁伸缩过程中不至于不锈钢板随梁的移动而滑脱。嵌放在梁底钢板上宽槽中的不锈钢板，厚度为3mm，梁在伸缩移动时，因为不锈钢板有很好的光洁度，又在四氟板表面上，所以摩擦阻力很小，四氟板式橡胶支座表面粘贴的聚四氟乙烯板厚为1.5mm左右，在四氟表平面上有直径8mm左右，深度约1mm的球冠形的储油坑，在安装时涂以“295”硅脂，以便进一步减小摩擦。

beam bottom plate and support plate, located at the beam endfulcrum, through the embedded or paste form in place, the westriver bridge between the steel plate and beam bottom fixed withepoxy resin paste. the thickness of the steel plate is 18mm, andthere is a deep 1.5mm wide slot for inserting stainless steelplate. the wide groove is made into a wedge, and the stainlesssteel plate does not slip along with the movement of the beamduring the expansion of the beam. embedded in the beam bottom platein the wide slot of the stainless steel plate, thickness of 3mm,beam in the telescopic movement, because stainless steel plate hasgood smoothness, and ptfe surface, so the friction resistance isvery small, the ptfe ptfe laminated rubber bearing surface paste isabout 1.5mm thick, in ptfe on the surface with a diameter of about8mm, spherical oil storage pit depth of about 1mm, installed in the"295" coated with grease, so as to further reduce the friction.
