GJZF4橡胶支座多少钱
GYZF4型四氟滑板橡胶支座应水平安装。并应设置上下钢板，四氟滑板与不锈钢板间应该涂放5201-2硅脂润滑油，安装后一定要设置防尘罩；支座的四氟滑板不得设置在支座底面，与四氟滑板接触的不锈钢板也不能设置在桥梁墩、台垫石上。
GYZF4 type PTFE slide rubber bearing shall be horizontally installed. And should be set on the steel plate, stainless steel plate and PTFE slide should apply 5201-2 grease lubricating oil, after installation must be set dustproof; PTFE sliding bearings should be set up in the bottom surface of the supporting seat, stainless steel plate contact with PTFE slide also cannot be set in the bridge pier and abutment pad stone.价格影响因素
Price influencing factors
第一质量：板式橡胶支座都是5mm橡胶和2mm钢板叠加而成，如果钢板厚度或者层数减少价格会下降；
First quality: sheet rubber bearings are 5mm rubber and 2mm steel plate superimposed, and if the thickness of steel plate or layer is reduced, prices will decline;
第二距离：因为有物流费用，所以距离越远价格越高；
Second distance: because there is logistics costs, so the farther away, the higher the price;
第三需要量：如果量少，需要单做磨具，那么无形中成本就增加了；
Third, the amount of demand: if the amount of small, need to do Abrasives alone, then virtually increase the cost;
第四是否有票据：增值税发票就会让产品价格略微有浮动。

圆型板式橡胶支座的优点及对施工的优势
Advantages of round plate rubber bearing and its advantages in construction
近些年桥梁施工用橡胶支座的要求非常之苛刻，国家严格要求桥梁工程的质量，高质的桥梁工程需要优质的桥梁支座。
In recent years, the requirements of rubber bearings for bridge construction are very demanding. The state strictly requires the quality of bridge engineering, and the high-quality bridge project needs high-quality bridge bearings.
1990年交通部公路规划设计院委托铁道部科学研究院对100多块圆形板式橡胶制造，进行了全面系统的实验研究。国外在生产矩形板式橡胶支座的同时，也生产圆型板式橡胶支座，其承载力可达12MN，有些国家还列入了国家标准。
In 1990, the highway planning and Design Institute of the Ministry of communications commissioned the Ministry of Railway Science Research Institute to conduct a comprehensive and systematic experimental study on the manufacture of more than 100 round rubber panels. In the production of foreign rectangular plate rubber support at the same time, also the production of circular plate rubber bearing, the bearing capacity of 12MN, some countries are also included in the national standard.
国内随着高等级公路的修建，弯桥、斜桥不断出现，因此也需要有适应该种桥梁的圆型板式橡胶支座。圆型板式橡胶支座具有以下优点：
With the domestic highway construction, bridge, bridge appear constantly, therefore also need to have a circular plate rubber bearing for bridge. The round plate rubber bearing has the following advantages:
（1）圆型板式橡胶支座可以弹性吸收上部结构各方向的变形；
(1) the round plate rubber bearing can elastically absorb the deformation of the upper structure in all directions;
（2）圆型板式橡胶支座的承压面与矩形支座相比，没有应力集中现象；
(2) there is no stress concentration in the bearing surface of the round plate rubber bearing compared with the rectangular support;
（3）圆型板式橡胶支座安装方便，可以不考虑方向性；
(3) the round plate rubber bearing is easy to install without taking into account the direction;
（4）圆型板式橡胶支座比起同样作用的其他类型支座造价低，维修养护方便。
(4) the round plate rubber bearing has lower cost and convenient maintenance and repair than other types of bearings of the same function.
现将主要实验结果介绍如下：
The main experimental results are presented as follows:
1.圆型板式橡胶支座的中心受压试验
Central compression test of 1. round plate rubber bearing
通过对78块圆型板式橡胶支座的中心受压试验，得出支座应力应变曲线中发现当应力超过15MPa时，应力应变曲线明显变陡，因此支座的容许压应力易取为12.5MPa。支座抗压弹性模量与形状系数的关系如下：E=66S-162
Through axial compression test of 78 pieces of circular plate rubber bearing, the bearing stress strain curve when the stress exceeds 15MPa, the stress-strain curve becomes steep, so the bearing allowable compressive stress and easy to get to 12.5MPa. The relationship between the compressive modulus of elasticity and the shape coefficient is as follows: E=66S-162

Shear modulus of 2. round plate type rubber bearing
通过54组支座的剪切实验，回归分析得出圆型板式橡胶支座的剪切模量G=1.0MPa。
The shear modulus of circular plate rubber bearing is obtained by regression analysis of 54 sets of bearing tests. G=1.0MPa.
3.圆型板式橡胶支座的转动实验
Rotation test of 3. round plate type rubber bearing
通过29组支座的转动实验，表明当橡胶层总厚度大于支座直径1/10时，圆型板式橡胶支座转动时，均可满足桥梁的转动性能要求，支座不会因为转动而脱空。
By rotating the experimental group 29 support, showed that when the total thickness of the rubber bearing layer is larger than the diameter of 1/10, circular plate rubber bearing rotates, can meet the performance requirements of rotating bridge bearing, not because of the rotation of void.
