橋梁板(ban)式橡(xiang)膠支座(zuo)是由(you)多層薄鋼(gang)板(ban)與(yu)多層橡(xiang)膠片硫化粘合而成一種普通橡(xiang)膠支座(zuo)產品,這種產品具有(you)足夠(gou)的豎向剛(gang)度,能夠(gou)將支座(zuo)上部構造的反力可(ke)靠的傳(chuan)遞給墩臺,支座(zuo)具有(you)良好(hao)的彈性,以(yi)應(ying)對(dui)橋梁的梁端的轉動；又有(you)較大(da)的剪切(qie)變形能力，以(yi)滿足上部構造的水平位移。
橋梁板式(shi)橡膠支座適用于公路橋梁、鐵路橋梁、城市立交橋。主要(yao)功能(neng)是將(jiang)上部的反力可靠地傳(chuan)遞給墩臺，并(bing)同時能(neng)完成梁體結構由于制動(dong)(dong)力溫(wen)度、混(hun)凝士的收(shou)縮徐變及(ji)荷載作用等引(yin)起的水平位移及(ji)梁端的轉動(dong)(dong)。
由多層高(gao)彈性的(de)(de)橡膠為主體材料，與薄(bo)鋼板鑲嵌、粘合、硫化(hua)而(er)成。該產品有足夠的(de)(de)豎向剛度(du)以承(cheng)受垂直荷載，且(qie)能將(jiang)上(shang)(shang)部構(gou)造(zao)的(de)(de)壓力可靠地傳遞給墩迨臺；有良好的(de)(de)彈性以適(shi)應(ying)梁端的(de)(de)轉動；有較大的(de)(de)剪(jian)切變形以滿足上(shang)(shang)部構(gou)造(zao)的(de)(de)水(shui)平(ping)位移。橡膠以其獨特的(de)(de)功能從(cong)根本上(shang)(shang)改善了橋梁支座的(de)(de)性能。
橋梁橡膠支座的正確安裝步驟：
先(xian)使(shi)支(zhi)(zhi)(zhi)(zhi)座(zuo)和支(zhi)(zhi)(zhi)(zhi)承墊石按設計要求(qiu)準(zhun)確(que)就位(wei)。架梁(liang)(liang)(liang)(liang)(liang)(liang)落(luo)(luo)梁(liang)(liang)(liang)(liang)(liang)(liang)時(shi)(shi)，T型(xing)梁(liang)(liang)(liang)(liang)(liang)(liang)的(de)(de)(de)縱軸線(xian)(xian)要與支(zhi)(zhi)(zhi)(zhi)座(zuo)中(zhong)(zhong)(zhong)心線(xian)(xian)重合；板(ban)(ban)梁(liang)(liang)(liang)(liang)(liang)(liang)、箱梁(liang)(liang)(liang)(liang)(liang)(liang)的(de)(de)(de)縱軸線(xian)(xian)與支(zhi)(zhi)(zhi)(zhi)座(zuo)中(zhong)(zhong)(zhong)心線(xian)(xian)相平(ping)行。為落(luo)(luo)梁(liang)(liang)(liang)(liang)(liang)(liang)準(zhun)確(que)，在(zai)架
跨(kua)板(ban)(ban)梁(liang)(liang)(liang)(liang)(liang)(liang)或箱梁(liang)(liang)(liang)(liang)(liang)(liang)時(shi)(shi)，可(ke)在(zai)梁(liang)(liang)(liang)(liang)(liang)(liang)底(di)劃好(hao)二個支(zhi)(zhi)(zhi)(zhi)座(zuo)的(de)(de)(de)十字位(wei)置(zhi)中(zhong)(zhong)(zhong)心，在(zai)梁(liang)(liang)(liang)(liang)(liang)(liang)的(de)(de)(de)端立面上標(biao)出兩個支(zhi)(zhi)(zhi)(zhi)座(zuo)的(de)(de)(de)位(wei)置(zhi)中(zhong)(zhong)(zhong)心線(xian)(xian)的(de)(de)(de)鉛直線(xian)(xian)，落(luo)(luo)梁(liang)(liang)(liang)(liang)(liang)(liang)時(shi)(shi)使(shi)之與墩臺上的(de)(de)(de)位(wei)置(zhi)中(zhong)(zhong)(zhong)心線(xian)(xian)相重合。以后數跨(kua)可(ke)依(yi)照
跨(kua)梁(liang)(liang)(liang)(liang)(liang)(liang)為基準(zhun)進行。在(zai)架梁(liang)(liang)(liang)(liang)(liang)(liang)落(luo)(luo)梁(liang)(liang)(liang)(liang)(liang)(liang)時(shi)(shi)要平(ping)穩(wen)，防止壓偏或產生初始剪切變形,大家可(ke)以參考鐵路橋梁(liang)(liang)(liang)(liang)(liang)(liang)板(ban)(ban)式(shi)橡膠(jiao)支(zhi)(zhi)(zhi)(zhi)座(zuo)規格(ge)表 。在(zai)安裝T型(xing)橋梁(liang)(liang)(liang)(liang)(liang)(liang)時(shi)(shi)，若橡膠(jiao)支(zhi)(zhi)(zhi)(zhi)座(zuo)比梁(liang)(liang)(liang)(liang)(liang)(liang)筋(jin)底(di)寬，則應在(zai)支(zhi)(zhi)(zhi)(zhi)座(zuo)與梁(liang)(liang)(liang)(liang)(liang)(liang)筋(jin)底(di)之間加設比支(zhi)(zhi)(zhi)(zhi)座(zuo)大的(de)(de)(de)鋼筋(jin)混(hun)凝土墊塊(kuai)或厚鋼板(ban)(ban)做過渡(du)層，以免支(zhi)(zhi)(zhi)(zhi)座(zuo)局 部受壓，而形成應力集中(zhong)(zhong)(zhong)。
