实践证明板式橡胶支座是一种构造简电、制造容易、用钢最少、成本低、工作性能可靠、安装方便的支座。在中小跨径桥梁上已基本代替了传统的钢制支座,并有向大吨位承载力发展的趋势。橡胶支座近年在我国桥梁工程上迅速推广使用,由于没有统一标准可遵循,出现了一些产品不能满足桥梁使用要求的现象。为了保证橡胶支座产品质量,使生产和使用单位对橡胶支座质量有统一标准进行质量检验,交通部于1986年下达了编制《公路桥梁板式橡胶支座规格系列》、《公路桥梁板式
Practice has proved that plate rubber bearing is a structure of electricity, easy to manufacture, the least steel, low cost, reliable performance, easy installation. Small and medium-span bridges have basically replaced the traditional steel bearings, and to large tonnage of the development trend. In recent years, rubber bearings in China’s rapid expansion of the bridge project to use, because there is no uniform standard to follow, there have been some products can not meet the requirements of the use of the bridge. In order to ensure the quality of rubber bearing products, the production and use of rubber bearing units on a uniform quality inspection standards issued by the Ministry of Transportation in 1986 issued a “highway bridge plate rubber bearing specifications series,” "Highway bridge plate
