橋梁彈性縫的效果：在于調節由車輛荷載和橋梁建筑材料所引起的上部結構之間的位移和聯合。斜交橋的彈性設備一旦被破壞，將嚴重影響行車的速度、舒適性與安全，乃至形成行車安全事故。

    橋(qiao)(qiao)梁(liang)(liang)彈(dan)(dan)性(xing)縫(feng)依(yi)照性(xing)能及(ji)安裝(zhuang)辦法能夠(gou)分為：GQF-C型(xing)(xing)(xing)(xing)、GQF-Z型(xing)(xing)(xing)(xing)、GQF-L型(xing)(xing)(xing)(xing)、GQF-F型(xing)(xing)(xing)(xing)、其中(zhong)GQF-MZL型(xing)(xing)(xing)(xing)數(shu)形式橋(qiao)(qiao)梁(liang)(liang)彈(dan)(dan)性(xing)縫(feng)設(she)備(bei)(bei)，是(shi)(shi)采用熱軋整(zheng)體(ti)成型(xing)(xing)(xing)(xing)的異型(xing)(xing)(xing)(xing)鋼材設(she)計的橋(qiao)(qiao)梁(liang)(liang)彈(dan)(dan)性(xing)縫(feng)設(she)備(bei)(bei)。 GQF-C型(xing)(xing)(xing)(xing)、GQF-Z型(xing)(xing)(xing)(xing)、GQF-L型(xing)(xing)(xing)(xing)、GQF-F型(xing)(xing)(xing)(xing)彈(dan)(dan)性(xing)縫(feng)設(she)備(bei)(bei)適(shi)(shi)用于彈(dan)(dan)性(xing)量80mm以下的的橋(qiao)(qiao)梁(liang)(liang)接縫(feng)， GQF-MZL型(xing)(xing)(xing)(xing)彈(dan)(dan)性(xing)縫(feng)設(she)備(bei)(bei)是(shi)(shi)由邊(bian)梁(liang)(liang)、中(zhong)梁(liang)(liang)、橫梁(liang)(liang)和連動組織組成的模(mo)數(shu)式橋(qiao)(qiao)梁(liang)(liang)彈(dan)(dan)性(xing)縫(feng)設(she)備(bei)(bei)，適(shi)(shi)用于彈(dan)(dan)性(xing)量80mm-1200mm的大(da)中(zhong)跨(kua)度橋(qiao)(qiao)梁(liang)(liang)。

    橋(qiao)(qiao)梁(liang)(liang)彈(dan)性縫(feng)一(yi)般(ban)有對(dui)接式、鋼制支承式、組合剪切式（板式）、模數支承式以及彈(dan)性設(she)(she)備。橋(qiao)(qiao)梁(liang)(liang)彈(dan)性縫(feng)是為滿足橋(qiao)(qiao)面變形的要(yao)(yao)求，通常(chang)在兩梁(liang)(liang)端(duan)之間、梁(liang)(liang)端(duan)與橋(qiao)(qiao)臺之間或橋(qiao)(qiao)梁(liang)(liang)的鉸接方位上設(she)(she)置彈(dan)性縫(feng)。要(yao)(yao)求彈(dan)性縫(feng)在平行(xing)(xing)、垂直(zhi)于橋(qiao)(qiao)梁(liang)(liang)軸線的兩個方向，均(jun)能(neng)自由彈(dan)性，結實牢靠，車輛行(xing)(xing)進過期應平順、無(wu)突跳與噪聲；要(yao)(yao)能(neng)避免雨水和廢物(wu)泥土進入阻塞；安(an)裝(zhuang)、查看(kan)、維護、消除污物(wu)都要(yao)(yao)簡易方便！
