GPZ系列盆式橡膠支座

盆式橡膠支座是鋼構件(底座和頂板構成一個盆形)與橡膠組合而成的新型橋梁支座,與鑄鋼輥軸支座和板式橡膠支座相比,具有承載能力大,水平位移量大、轉動靈活等特點,且重量輕,結構緊湊,構造簡單,建筑高度低,加工制造方便,節省鋼材,降低造價等優點,是適宜于大垮橋梁使用的較理想的支座。本系列支座承載力為31個級別,承載力0.8MN-60MN,能滿足大型橋梁建造的需要。
盆式橡膠支座的構造特點及功能:

盆式橡膠支座是利用被半封閉鋼制盆腔內的彈性橡膠塊,在三向受力狀態下具有流體的性質特點,來實現橋梁上部的轉動,同時依靠中間鋼板上的F4板與上座板的不銹鋼板之間的低摩擦系數來實現上部結構的水平位移,使支座所承受的剪切不再由橡膠完全承擔,而間接作用于鋼制底盆及F4板與不銹鋼之間{TodayHot}的滑移上。從試驗的數據來看,橡膠處于三向約束狀態時的抗壓彈性模量為50000kg/cm2,比無側向約束的抗壓彈性模量增大近20倍,因而支座承載能力大為提高,解決了板式橡膠支座承載能力的局限,能滿足大的支承反力、大的水平位移及轉角要求。
