一、板式橡胶支座按形状划分：
First, the plate rubber bearings are divided into shapes:
矩形板式橡胶支座、圆形板式橡胶支座、球冠圆板式橡胶支座、圆板坡形橡胶支座
Rectangular plate rubber bearing, circular rubber bearing, spherical plate type rubber bearing plate, slope shaped rubber bearings
二、板式橡胶支座用途：
Two, the use of plate rubber bearings:
该产品主要适用于公路桥梁、铁路桥梁、城市立交桥。主要功能是将上部的反力可靠地传递给墩台，并同时能完成梁体结构由于制动力、温度、混凝土的收缩徐变及荷载作用等引起的水平位移及梁端的转动。
The product is mainly applicable to highway bridges, railway bridges and urban overpasses. The main function is to the upper part of the counter force and reliably transfer to the pier, and also can complete the structure due to rotation of horizontal displacement caused by the braking force, temperature, shrinkage and creep of concrete and load and beam end.
三、板式橡胶支座特点：
Three, the characteristics of plate rubber bearings:
1、球冠圆板橡胶支座：球冠圆板橡胶支座是改进后的圆形板式橡胶支座。
1, the spherical plate rubber bearing: spherical plate rubber bearing is improved after the round plate rubber bearing.
其中间层橡胶和钢板布置与圆形板式橡胶支座完全相同，而在支座顶面用纯橡胶制成球形表面，球面中心橡胶最大厚度为4－13mm，球面边缘15mm，以适应3％到4％纵横坡下，梁与支座接触面的中心趋于圆形板式橡胶支座的中心。
The middle layer of rubber and steel plate arrangement and circular plate rubber bearing the same, and in the top surface of the spherical surface bearing made of pure rubber, rubber spherical center of the maximum thickness of 4 13mm, spherical edge 15mm, to accommodate 3% to 4% vertical slope, and the bearing contact surface of the beam center tends to circular plate rubber support center.
梁端反力通过球面表面橡胶逐渐扩散传至下面几层钢板和橡胶层。在橡胶支座底面加一圈直径D=2.5mm的半圆形橡胶圆环，支座受力时首先由底部圆环变(查看详情)桥梁橡胶支座的作用 3、生产工艺：板式橡胶支座现在还没有完全实现自动话生产，硫化之前的步骤基本都是手工操作，下片，裁片，叠层等工序的好坏与工人的熟练程度有很大关系
The reaction force at the end of the beam diffuses gradually through the surface rubber of the spherical surface to the lower layers of steel plate and rubber layer. In the semi circular rubber ring rubber bearing bottom with a ring diameter of D=2.5mm, the bearing force when the first from the bottom of the circle (see details) 3, the role of bridge rubber bearings production process: plate rubber bearing is not fully automatic production, curing before the basic steps are manual, chip that piece, have a great relationship with the quality of proficiency in the processes of the stack of workers

桥梁橡胶支座的作用对于铁路路梁桥梁，由于制动力影响较大，固定支座与活动支座的布置应根据一下原则 1、对桥跨结构而言，使梁的下弦在制动力的作用下受压，并能抵消一部分竖向荷载下弦产生的拉力； 2、对桥墩而言，让制动
Rubber support role for the railway bridge, due to power system influence, the fixed support and the movable support shall be arranged according to the principle of 1, on the bridge structure, the best beam bottom pressure in the braking force under the action, and can offset part of vertical loading force of 2 and lower; on the pier, better braking
