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、安装方便、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。
The plate rubber bearing (GJZ, GYZ Series) is made of multilayer rubber and thin steel plate inlaid, glued and vulcanized. This product has enough vertical stiffness to bear vertical load, and the upper structure of the pressure can be reliably transferred to the pier; have good flexibility to adapt to the rotation of the beam end; to meet the horizontal displacement of superstructure of large shear deformation; has the advantages of simple structure, convenient installation, saving steel, low price, easy maintenance, easy replacement. This product has a good shockproof effect, can reduce the dynamic impact load on the bridge and pier.
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、GYZF4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。广泛用于本工厂，矿山，机械，电子，机械设备，厨房设备。
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, GYZF4). 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. It is widely used in the factory, mine, machinery, electronics, mechanical equipment, kitchen equipment.
四氟滑板的适用范围：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。
The scope of application of tetrafluoroplank: A. as a movable support: it is mainly used for long span bridge simple supported beam continuous slab bridge and multi span continuous beam bridge for span > 30 meters.
b.作为滑块块使用连续梁顶推、T型梁横移、大型设备滑移。
B. is used as slider block to use continuous beam top push, T beam cross shift, and large equipment slip.
