文圣盆式文圣橡膠支座的安(an)裝(zhuang)是為了保證橋(qiao)梁(liang)(liang)的安(an)全使用(yong)、橋(qiao)梁(liang)(liang)上下(xia)部結構(gou)間力(li)的傳遞符合設計要(yao)求(qiu)和橋(qiao)梁(liang)(liang)使用(yong)功(gong)能正常發(fa)揮的重要(yao)環節(jie)之一。在施工(gong)過程中，應掌握好支座(zuo)的安(an)裝(zhuang)質量及(ji)控制要(yao)點。

　　文圣盆式文圣橡膠支座克服了我們以往板式文圣橡膠支座的一些(xie)特(te)點(dian)，其主要產(chan)品構(gou)造特(te)點(dian)有兩個(ge)：

　　1、是將橡膠塊放(fang)置凹形的(de)缸盆內，使橡膠處于有(you)側限受壓(ya)狀(zhuang)態，大(da)大(da)提高(gao)了支座的(de)承載力;

　　2、是利用嵌放在金屬盆頂面的填充四氟乙烯板與不銹鋼板相對摩擦系數小的特性，保證了活動支座能夠滿足梁水平移動的要求。所以文圣盆式文圣橡膠支座一經問世，就被廣泛應用于大、中(zhong)型橋梁(liang)和(he)城(cheng)市高架橋中(zhong)。

　　盆式文圣橡膠支座分為固(gu)定支(zhi)(zhi)(zhi)座(zuo)和活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)支(zhi)(zhi)(zhi)座(zuo)。活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)支(zhi)(zhi)(zhi)座(zuo)又有(you)單向(xiang)(xiang)活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)支(zhi)(zhi)(zhi)座(zuo)和雙向(xiang)(xiang)活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)支(zhi)(zhi)(zhi)座(zuo)。一般來說，橋(qiao)梁固(gu)定端(duan)(duan)選用(yong)固(gu)定支(zhi)(zhi)(zhi)座(zuo)，活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)端(duan)(duan)選用(yong)活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)支(zhi)(zhi)(zhi)座(zuo)。對于盆式雙向(xiang)(xiang)活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)支(zhi)(zhi)(zhi)座(zuo)能在水平(ping)面內任意方(fang)向(xiang)(xiang)移動(dong)(dong)(dong)(dong)(dong)(dong)。因(yin)此，彎橋(qiao)的活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)墩臺上(shang)應(ying)選擇這種制(zhi)作。至于單向(xiang)(xiang)活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)支(zhi)(zhi)(zhi)座(zuo)，可在直橋(qiao)中使用(yong)。但應(ying)注意，只有(you)當活(huo)(huo)動(dong)(dong)(dong)(dong)(dong)(dong)墩上(shang)只有(you)一個支(zhi)(zhi)(zhi)座(zuo)，或者支(zhi)(zhi)(zhi)座(zuo)間橫向(xiang)(xiang)溫度(du)伸縮(suo)量很小的情況下才宜選用(yong)。
