板式橡胶支座是公路中小型桥梁中比较常用的产品，它分为普通板式橡胶支座、四氟板式橡胶支座。对于普通型桥梁支座适用于跨度小于30m、位移量较小的桥梁.不同的平面形状适用于不同的桥跨结构,正交桥梁用矩形支座;曲线桥、斜交桥及圆柱墩桥用圆形支座.
Plate rubber bearings are commonly used in small and medium highway bridges. They are divided into ordinary plate rubber bearing and PTFE plate rubber bearing. For the ordinary type of bridge bearing for bridge in a span of less than 30m, small displacement. Different plane shapes for different bridge structure, bridge with orthogonal rectangular bearings; bearing with circular curve bridge, skew bridge and bridge pier.对于四氟乙烯板式橡胶支座适用于大跨度、多跨连续、简支梁连续板等结构的大位移量桥梁。它还可用作连续梁顶推及T型梁横移中的滑块。矩形、圆形四氟板式橡胶支座的应用分别与矩形、圆形普通板式橡胶支座相同。
For PTFE laminated rubber bearing is suitable for large span and multi span continuous beam, continuous plate structure of the large displacement bridge. It is also used as a continuous beam and T beam traversing the top slider in the. The application of rectangular and circular PTFE plate rubber bearings is the same as that of rectangular and circular ordinary rubber bearings.
产品选型
Product selection
a：查看板式橡胶支座的安装施工图纸，主要注意板式橡胶支座的规格型号、高度、承载力等主要技术参数。四氟滑板橡胶支座还要注意预埋钢板的尺寸和安装位置及方向； b：选用板式橡胶支座时,支座的最大承载力应与桥梁支点反力相吻合,其容许偏差范围宜为±10%；
A: view the installation and construction drawings of plate rubber bearings, mainly pay attention to the specifications, type, height, bearing capacity and other main technical parameters of plate rubber bearings. PTFE sliding plate rubber bearings but also pay attention to the embedded steel installation position and size and direction; B: selection of plate rubber bearing, bearing the maximum bearing capacity should be consistent with the bridge pivot reaction, the allowable deviation range appropriate for + 10%;
c： 对于弯、坡、斜、宽桥梁，宜选用圆形板式橡胶支座。公路桥梁工程不许使用带球冠或坡形的橡胶支座；

d：当桥梁纵坡坡度不大于1%时，板式橡胶支座可直接设置于墩台上，但应考虑纵坡影响所需要的厚度。当纵坡坡度大于1%时，应采用预埋钢板（加楔形钢板）、混凝土垫块（带坡度的垫石）或其他措施将梁底调平，保证支座平置。板式橡胶支座应按JTG D62的有关规定验算并在验算满足规定要求后方可使用。
D: when the bridge longitudinal slope is not greater than 1%, the laminated rubber bearing can be directly arranged on the pier, but should consider the influence of the required thickness of longitudinal slope. When the longitudinal slope is greater than 1%, the embedded steel plate (wedge steel plate), concrete cushion block (with slope cushion stone) or other measures should be used to adjust the bottom of the beam to ensure the flat support. The plate type rubber bearing should be checked according to the relevant provisions of JTG D62 and can be used before the checking calculation meets the specified requirements.
e：GJZF4、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。
Horizontal mounting of e:GJZF4 and GYZF4 type PTFE slide rubber bearings. 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；

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 are logistics costs, so the farther the distance, 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 requirements: if the amount is small, need to do Abrasives only, then the invisible cost increased;
第四是否有票据：增值税发票就会让产品价格略微有浮动。
Fourth whether there is a bill: value-added tax invoice will make the product price slightly floating.
