矩形板式橡膠支座180*180*37mm我公司專業(yè)生產(chǎn)廠家直銷

一、GJZ（矩形）板式橡膠支座特點
First, GJZ (rectangular) plate rubber bearing characteristics
支座由多動橡膠片和薄鋼板經(jīng)粘合硫化加壓而成，它的功能是將上部結(jié)構(gòu)的作用力傳遞給墩臺，并能適用梁部結(jié)構(gòu)秘產(chǎn)生的水平位移和轉(zhuǎn)角。
Support by the hyperactivity rubber sheet and thin steel plates by adhesive curing pressure and become, its function is to transfer the forces of the upper structure to the pier, and can be applied to produce beam structure's horizontal displacement and rotation.

二、矩形板式橡膠支座（GJZ)常用規(guī)格：例：短邊尺寸為：100mm,長邊為150mm,厚度21mm,則表示為：100x150x21.
Two, rectangular plate rubber bearing (GJZ) commonly used specifications: example: short side size is: 100mm, long side is 150mm, thickness 21mm, is expressed as: 100x150x21.
GJZ100x150x21、GJZ100x150x28、GJZ100x200x21、GJZ100x200x28、GJZ150x150x21、GJZ150x150x28、GJZ200x200x21、GJZ200x300x28。
GJZ100x150x21, GJZ100x150x28, GJZ100x200x21, GJZ100x200x28, GJZ150x150x21, GJZ150x150x28, GJZ200x200x21, GJZ200x300x28.
三、板式橡膠支座分類
Three. Classification of plate rubber bearings
1、支座分普通型和耐寒型兩種。
1, the bearing is divided into two types of common and cold resistant.
2、普通型膠料采用氯丁橡膠配制面成，在-25℃～+60℃溫度下使用。
2. The ordinary rubber material is made of chloroprene rubber and is used at the temperature of -25 ~ +60 centigrade.
3、耐寒型膠料采用天然橡膠配制而成，在-40℃～+60℃溫度下使用。
3. Cold resistant rubber material is made of natural rubber, and is used at -40 ~ +60 centigrade temperature.
