? 隨(sui)著鋼結構工(gong)業的(de)發展(zhan)弧形(xing)管(guan)(guan)片螺(luo)栓也得到了廣(guang)泛(fan)(fan)的(de)應用。到目(mu)前為止，在橋梁、塔架、廠房、鍋爐、高(gao)(gao)層民(min)用建筑和桅桿結構等施工(gong)領(ling)域都(dou)廣(guang)泛(fan)(fan)應用弧形(xing)管(guan)(guan)片螺(luo)栓，弧形(xing)管(guan)(guan)片螺(luo)栓具有(you)施工(gong)周期短、安(an)全性高(gao)(gao)、安(an)裝方便等優點，可以作為住宅整體安(an)裝的(de)連接件(jian)，被廣(guang)泛(fan)(fan)應用。
目前建筑(zhu)行(xing)業比(bi)較(jiao)先進(jin)的(de)鋼結(jie)(jie)構連接件就是(shi)弧形(xing)管片(pian)(pian)螺(luo)栓(shuan)(shuan)(shuan)了。主要具有結(jie)(jie)構簡(jian)單、使用(yong)方便、可(ke)拆換、傳力均勻等(deng)好處。弧形(xing)管片(pian)(pian)螺(luo)栓(shuan)(shuan)(shuan)采用(yong)壓力式連接或者(zhe)摩擦式連接需要根據(ju)施(shi)工(gong)工(gong)程的(de)設計規格。內地鋼結(jie)(jie)構專用(yong)弧形(xing)管片(pian)(pian)螺(luo)栓(shuan)(shuan)(shuan)有兩(liang)種，鋼結(jie)(jie)構用(yong)大(da)六角弧形(xing)管片(pian)(pian)螺(luo)栓(shuan)(shuan)(shuan)和鋼結(jie)(jie)構用(yong)抗扭剪切弧形(xing)管片(pian)(pian)螺(luo)栓(shuan)(shuan)(shuan)，它(ta)們又叫做GB / t3632、GB / t1228；
采用(yong)(yong)專用(yong)(yong)棘輪(lun)扳手和扭力扳手對(dui)弧形(xing)(xing)管(guan)片螺(luo)(luo)栓進行(xing)初、終擰緊。弧形(xing)(xing)管(guan)片螺(luo)(luo)栓的(de)防(fang)腐(fu)處理(li)用(yong)(yong)的(de)比較(jiao)多的(de)有(you)涂裝防(fang)腐(fu)漆、熱鍍鋅（熱浸鋅）、粉末鍍鋅、達(da)克(ke)羅等(deng)。弧形(xing)(xing)管(guan)片螺(luo)(luo)栓的(de)試驗一(yi)般是分批進行(xing)的(de)。一(yi)個批次(ci)為3000套，每批分8套為一(yi)組。
對于(yu)弧形(xing)(xing)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)栓(shuan)(shuan)，它常用(yong)的(de)(de)表面處理有達克羅(luo)（學名：鋅(xin)(xin)基鉻酸鹽(yan)）、粉(fen)(fen)末鍍(du)鋅(xin)(xin)、熱浸鋅(xin)(xin)（熱鍍(du)鋅(xin)(xin)）、多(duo)元分復(fu)合(he)粉(fen)(fen)末鍍(du)鋅(xin)(xin)等(deng)(deng)等(deng)(deng)。弧形(xing)(xing)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)栓(shuan)(shuan)的(de)(de)表面處理是至關重要(yao)的(de)(de)。由于(yu)弧形(xing)(xing)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)栓(shuan)(shuan)安(an)裝在地下，有著連接和緊固管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)作用(yong)。弧形(xing)(xing)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)栓(shuan)(shuan)位于(yu)潮濕的(de)(de)環境中，容易造成(cheng)弧形(xing)(xing)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)栓(shuan)(shuan)腐蝕(shi)生銹。因此(ci)，如果(guo)弧形(xing)(xing)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)栓(shuan)(shuan)表面處理不符合(he)工程需求，導(dao)致弧形(xing)(xing)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)栓(shuan)(shuan)在使用(yong)過(guo)程中出(chu)現(xian)腐蝕(shi)、生銹等(deng)(deng)現(xian)象，等(deng)(deng)弧形(xing)(xing)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)栓(shuan)(shuan)內部開始腐蝕(shi)后(hou)，會(hui)影響(xiang)弧形(xing)(xing)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)栓(shuan)(shuan)的(de)(de)力學性(xing)能和抗(kang)拉強度。
