如果检测板式橡胶支座要哪些项目？对于板式橡胶支座的检测要采用微机控制橡胶支座压剪试验机完全支持并实现JT/T4-2004《公路桥梁板式橡胶支座力学性能试验方法》中对试验设备要求.该文件中关键词 标准 均为该标准缩写。橡胶支座试验机主机采用四立柱结构，纵向液压缸竖直安装在底座上，主活塞上连接下承载粱,上横梁四套蜗轮蜗杆减速，带动螺母旋转后，可升降,加长螺母保证其承受巨大的侧向力时仍然保持其几何精度.上下承载梁之间的距离通过纵向液压缸及上横梁来调整,以适应不同厚度的试样.橡胶支座承载板与试样接触表面做防滑处理，同时带有试样定位用辅助浅刻线。下承载板长度适用于转角试验要求，安装有转角试验加荷伺服油缸。橡胶支座包括：盆式橡胶支座、板式橡胶支座、聚四氟乙烯滑板式橡胶支座、桥梁式橡胶支座、橡胶止水带、聚乙烯闭孔泡沫板。
该工程是无锡**采用桥梁整体**升工艺进行全桥盆式支座的更换施工，**升施工面临较大技术难题：其一，是将连续箱梁桥体在空间上的多个临时支撑点同步平稳抬起，前后左右支点间的高差结构上不允许**过3mm；其二，是现状老桥的实际高度因原施工局部误差、使用过程中不均匀变形造成的现状桥实际高度与原设计高度有偏差，**升过程中的桥梁高度需监控，**完桥梁回落高度更需严格控制；其三，就是**升的高度不可能非常高，在狭小的空间里拆除原有支座、钢板，同时更换新的支座、钢板以及少量补强混凝土的施工要求都十分精细。盆式橡胶支座的检验项目 检验依据 检验频次橡胶支座原材料及部件性能

桥梁支座在桥梁结构中起着承上启下的作用，它既要将作用于桥梁上部结构的全部荷载传递到墩台上，又要保证作用于桥跨结构的水平力按设计要求合理地分配到墩台上，使桥梁结构的实际受力情况与设计计算时的图式相符。
The bridge support plays a role in the bridge structure. It must transmit all the loads acting on the upper structure of the bridge to the abutment, and ensure that the horizontal force acting on the bridge span is reasonably distributed to the pier according to the design requirements. On the stage, the actual force of the bridge structure is consistent with the design at the time of design calculation.
对于工程设计单位，如果支座在设计时若采用的设计参数不合理、选用的支座型式及结构不合理，会给使用中的桥梁结构带来很大的附加应力和变形，不能满足结构受力、变形的需要，还会直接影响桥梁结构的安全及使用寿命。
For the engineering design unit, if the design parameters used in the design of the support are unreasonable, the selected support type and the structure are unreasonable, it will bring great additional stress and deformation to the bridge structure in use, which cannot meet the structural acceptance. The need for force and deformation will directly affect the safety and service life of the bridge structure.
任何一种新型支座的出现，都必须经过大量试验取得确切数据后确定有关的设计参数，以指导设计人员正确地选用合适的产品。
The emergence of any new type of support must be determined through extensive testing to determine the relevant design parameters to guide the designer to select the right product.
随着板式支座在桥梁上的广泛应用，其产品重要性也日益受到重视。
With the wide application of plate supports on bridges, the importance of their products has also received increasing attention.
因此我们对支座的选用、布置、设计计算等方面进行了科学技术分析，目的就是让用户得到更好的产品。
Therefore, we have carried out scientific and technical analysis on the selection, arrangement, design calculation and other aspects of the support, the purpose is to let users get better products.
对于普通板式橡胶支座适用于跨度小于30mm、位移量较小的桥梁。
For ordinary plate rubber bearings, it is suitable for bridges with a span of less than 30mm and a small displacement.
不同的平面形状适用于不用的桥跨结构；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。
Different planar shapes are suitable for unused bridge span structures; rectangular supports for orthogonal bridges; circular supports for curved bridges, oblique bridges and cylindrical pier bridges.
四氟板式橡胶支座适用大跨度、多跨连续、简支梁连续板等结构的大位移量桥梁。
The PTFE plate rubber bearing is suitable for large displacement bridges with large span, multi-span continuous and simply supported beam continuous plates.
它还可用作连续梁**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。
It can also be used as a slider for continuous beam push and T-beam traverse. Rectangular and circular PTFE plate rubber bearings are used in the same way as rectangular and round plain plate rubber bearings.
坡形板式橡胶支座的安装与施工橡胶支座处于桥梁上、下部构造连接点的重要位置，它的可靠程度直接影响桥梁结构的安全度与耐久度。
The installation and construction of the slope-shaped rubber bearing is an important position of the joint between the upper and lower structures of the bridge. Its reliability directly affects the safety and durability of the bridge structure.
因此除了确保橡胶支座的设计选型合理，及加工质量符合技术标准外，正确的施工与安装是橡胶支座应用成功与否的关键所在。
Therefore, in addition to ensuring that the design of the rubber bearing is reasonable and the processing quality meets the technical standards, the correct construction and installation is the key to the success of the rubber bearing application.
