Product Description:  

1 Product name: highway bridge plate rubber bearing;  Rubber bearing;  Plate rubber bearing;  Slide plate rubber bearing  

2 product classification: ordinary plate rubber bearing (rectangular, circular);  Sliding plate rubber bearing (rectangular, circular).  

3 Applicable temperature: normal temperature -25℃~60℃;  Cold-resistant -40℃~-60℃.  

4 main materials: natural rubber, neoprene rubber;  Stiffened steel plate;  Stainless steel plate;  Anchor bolt;  The skateboard;  Silicon grease.  Dust cover.  

5 Load grade: 100KN-10000KN.  

The function of bridge supports is to transmit static and dynamic loads, braking force and wind force to piers and abutments.  The structure of the support must be able to meet the displacement and torsion caused by traffic, temperature changes, earthquakes, prestress, shrinkage and creep, etc.  It can be seen that the bearing is the most important component in the bridge, and its quality requirements must be high standard.  

Plate rubber bearing (GJZ, GYZ series) is made of multi-layer rubber and thin steel plate inlaid, bonded and vulcanized.  The product has enough vertical stiffness to bear the vertical load, and can reliably transfer the pressure of the superstructure to the pier;  Good elasticity to adapt to the rotation of the beam end;  There is a large shear deformation to meet the horizontal displacement of the superstructure;  It has the characteristics of simple structure, safe and convenient, steel saving, low price, easy maintenance and easy replacement.  This product has a good shockproof effect, can reduce the impact of dynamic load on the bridge structure and pier.  

Tetrafluoroethylene sliding plate rubber bearing referred to as tetrafluoroethylene sliding plate bearing (GJZF4, GYZF4 series), is made of polytetrafluoroethylene plate with a thickness of 2-4mm glued on the ordinary plate rubber bearing according to the bearing size.  Ptfe sliding plate bearing in addition to the vertical stiffness and elastic deformation of ordinary plate rubber bearing, and can withstand vertical load and adapt to the rotation of the beam end, the use of ptfe plate and stainless steel plate between the low friction coefficient (μ F ≤0.08) can make the horizontal displacement of the bridge superstructure is not limited span system.  30 meters of long-span bridge, simple beam continuous plate bridge and multi-span continuous beam bridge can be used as movable support;  Continuous beam push, T beam cross movement and large equipment slip can be used as sliding blocks.

6桥梁支座的功能是将静载和动载力、制动力和风力传送到桥墩和桥台。支座的结构必须能满足由交通、温度变化、地震、预应力、收缩徐变等产生的位移和扭转。由此可见，支座是桥梁中最重要的元件，其质量要求必须是高标准的。

板式橡胶支座（GJZ、GYZ系列）由多层橡胶与薄钢板镶嵌、粘合、硫化而成。该产品有足够的竖向刚度以承受垂直荷载，且能将上部构造的压力可靠地传递给墩台；有良好的弹性以适应梁端的转动；有较大的剪切变形以满足上部构造的水平位移；具有构造简单、安全方便、节省钢材、价格低廉、养护简便、易于更换等特点。本品有良好的防震作用，可减少动载对桥跨结构与墩台的冲击作用。

四氟乙烯滑板式橡胶支座简称四氟滑板式支座（GJZF4、GYZF4系列），是于普通板式橡胶支座上按照支座尺寸大小粘复一层厚2-4mm的聚四氟乙烯板而成。四氟滑板式支座除具有普通板式橡胶支座的竖向刚度与弹性变形，且能承受垂直荷载及适应梁端转动外，利用聚四氟乙烯板与不锈钢板间的低摩擦系数（μf≤0.08）可使桥梁上部构造水平位移不受限跨度制。30米的大跨度桥梁、简支梁连续板桥和多跨连续梁桥可作活动支座使用；连续梁顶推、T型梁横移和大型设备滑移可作滑块使用。
