GJZF4橡膠支座多少錢

GYZF4型四氟滑板橡膠支座應水平安裝。并應設(shè)置上下鋼板，四氟滑板與不銹鋼板間應該涂放5201-2硅脂潤滑油，安裝后一定要設(shè)置防塵罩；支座的四氟滑板不得設(shè)置在支座底面，與四氟滑板接觸的不銹鋼板也不能設(shè)置在橋梁墩、臺墊石上。

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.
價格影響因素
Price influencing factors
第一質(zhì)量：板式橡膠支座都是5mm橡膠和2mm鋼板疊加而成，如果鋼板厚度或者層數(shù)減少價格會下降；
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;
第二距離：因為有物流費用，所以距離越遠價格越高；
Second distance: because there is logistics costs, so the farther away, the higher the price;
第三需要量：如果量少，需要單做磨具，那么無形中成本就增加了；
Third, the amount of demand: if the amount of small, need to do Abrasives alone, then virtually increase the cost;

第四是否有票據(jù)：增值稅發(fā)票就會讓產(chǎn)品價格略微有浮動。

Fourth whether there is a bill: value-added tax invoice will let the product price slightly floating.
圓型板式橡膠支座的優(yōu)點及對施工的優(yōu)勢
Advantages of round plate rubber bearing and its advantages in construction
近些年橋梁施工用橡膠支座的要求非常之苛刻，國家嚴格要求橋梁工程的質(zhì)量，高質(zhì)的橋梁工程需要優(yōu)質(zhì)的橋梁支座。
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年交通部公路規(guī)劃設(shè)計院委托鐵道部科學研究院對100多塊圓形板式橡膠制造，進行了全面系統(tǒng)的實驗研究。國外在生產(chǎn)矩形板式橡膠支座的同時，也生產(chǎn)圓型板式橡膠支座，其承載力可達12MN，有些國家還列入了國家標準。
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.
國內(nèi)隨著高等級公路的修建，彎橋、斜橋不斷出現(xiàn)，因此也需要有適應該種橋梁的圓型板式橡膠支座。圓型板式橡膠支座具有以下優(yōu)點：
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）圓型板式橡膠支座可以彈性吸收上部結(jié)構(gòu)各方向的變形；
(1) the round plate rubber bearing can elastically absorb the debation of the upper structure in all directions;
（2）圓型板式橡膠支座的承壓面與矩形支座相比，沒有應力集中現(xiàn)象；
(2) there is no stress concentration in the bearing surface of the round plate rubber bearing compared with the rectangular support;
（3）圓型板式橡膠支座安裝方便，可以不考慮方向性；
(3) the round plate rubber bearing is easy to install without taking into account the direction;
（4）圓型板式橡膠支座比起同樣作用的其他類型支座造價低，維修養(yǎng)護方便。
(4) the round plate rubber bearing has lower cost and convenient maintenance and repair than other types of bearings of the same function.
現(xiàn)將主要實驗結(jié)果介紹如下：
The main experimental results are presented as follows:
1.圓型板式橡膠支座的中心受壓試驗
Central compression test of 1. round plate rubber bearing
通過對78塊圓型板式橡膠支座的中心受壓試驗，得出支座應力應變曲線中發(fā)現(xiàn)當應力超過15MPa時，應力應變曲線明顯變陡，因此支座的容許壓應力易取為12.5MPa。支座抗壓彈性模量與形狀系數(shù)的關(guān)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

2.圓型板式橡膠支座的剪切模量
Shear modulus of 2. round plate type rubber bearing
通過54組支座的剪切實驗，回歸分析得出圓型板式橡膠支座的剪切模量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.圓型板式橡膠支座的轉(zhuǎn)動實驗
Rotation test of 3. round plate type rubber bearing
通過29組支座的轉(zhuǎn)動實驗，表明當橡膠層總厚度大于支座直徑1/10時，圓型板式橡膠支座轉(zhuǎn)動時，均可滿足橋梁的轉(zhuǎn)動性能要求，支座不會因為轉(zhuǎn)動而脫空。

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 perbance requirements of rotating bridge bearing, not because of the rotation of void.
