四氟滑板式橋梁支座也稱聚四氟板式文峰橡膠支座，除具有普通板式文峰橡膠支座的(de)豎(shu)向剛度(du)與彈性變形，能(neng)承受(shou)垂直荷載及適應梁(liang)端轉動(dong)外(wai)，因四氟乙烯(xi)與梁(liang)底不(bu)銹鋼板間的(de)低(di)摩擦系數(μ≤0.03)可使橋梁(liang)上部構(gou)造(zao)的(de)水平位移(yi)(yi)不(bu)受(shou)限制，跨度(du)>30米的(de)大跨度(du)橋梁(liang)、簡支梁(liang)連(lian)(lian)(lian)續板橋和多跨連(lian)(lian)(lian)續梁(liang)橋可作活動(dong)支座使用;連(lian)(lian)(lian)續梁(liang)頂推、T型梁(liang)橫移(yi)(yi)和大型設(she)備滑移(yi)(yi)可作滑塊使用。

　　盆式支座根據應用范圍可以分為三大類：公路橋梁文峰盆式文峰橡膠支座、鐵路橋梁文峰盆式文峰橡膠支座及盆式文峰橡膠支座的衍生品(pin)。常(chang)(chang)用的公路(lu)(lu)(lu)盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)型(xing)號有：GPZ盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)和GPZ(Ⅱ)盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)(依據GT391-1999) ,GPZ(KZ)盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)等(deng)幾個(ge)系列。常(chang)(chang)用的鐵(tie)(tie)(tie)路(lu)(lu)(lu)盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)有TPZ-I鐵(tie)(tie)(tie)路(lu)(lu)(lu)盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)，TPZ標鐵(tie)(tie)(tie)路(lu)(lu)(lu)盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)，專(zhuan)橋(qiao)8156鐵(tie)(tie)(tie)路(lu)(lu)(lu)橋(qiao)梁(liang)支(zhi)(zhi)座(zuo)。 盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)的衍生品(pin)種類很多，比如 QPZ盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)、KPZ系列盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)、彈性(xing)減(jian)震球型(xing)鋼支(zhi)(zhi)座(zuo)、自調高(gao)盆(pen)(pen)(pen)(pen)式(shi)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)支(zhi)(zhi)座(zuo)等(deng)。

　　每一類根據位移形式可分(fen)為固定(GD)、單(dan)向活(huo)動(DX)和(he)雙向活(huo)動(SX)三種(zhong)
