輕鋼龍骨石膏(gao)板天花吊頂施工工藝(yi) 打造時尚美觀(guan)天花

步驟一：清理現場：對施工現場墻、地面、灰(hui)塵(chen)、垃圾進(jin)行清理。

步驟二：彈線定位：根據設計及現場要求、確(que)定50cm水平線，用尺量至頂面(mian)(mian)設計標高(gao)線，在四周墻面(mian)(mian)彈頂面(mian)(mian)水平線(水平線應(ying)以付龍(long)(long)骨底(di)面(mian)(mian)為準)，然后畫出龍(long)(long)骨位置(zhi)線和(he)吊點(dian)(桿)布置(zhi)線。

步驟三：安裝吊桿

a.角(jiao)(jiao)鐵(tie)(tie)吊件及吊筋加(jia)工：角(jiao)(jiao)鐵(tie)(tie)吊件采用(yong)L30*30角(jiao)(jiao)鐵(tie)(tie)加(jia)工，在(zai)角(jiao)(jiao)鐵(tie)(tie)面(mian)(mian)上劃出中心線，對(dui)(dui)應(ying)打出一排 10或(huo) 8的孔、孔距45mm左右，再將角(jiao)(jiao)鐵(tie)(tie)分(fen)段切(qie)割下來。不上人(ren)吊件可用(yong)小角(jiao)(jiao)鐵(tie)(tie)制作， 吊點(dian)應(ying)在(zai)屋面(mian)(mian)板下均勻分(fen)布(施工前(qian)應(ying)對(dui)(dui)現場(chang)進行檢查，布點(dian)應(ying)避(bi)開(kai)頂(ding)面(mian)(mian)空調風筒(tong)及各種管道，若避(bi)不開(kai)時可采取角(jiao)(jiao)鐵(tie)(tie)補充吊點(dian))，大面(mian)(mian)積或(huo)上人(ren)吊頂(ding)吊點(dian)間(jian)距為≤1000mm，一般吊頂(ding)的吊點(dian)間(jian)距為≤1200mm，用(yong)電錘(chui)在(zai)頂(ding)上打孔，放置(zhi)膨脹栓擰緊固定于頂(ding)面(mian)(mian)上。

b.根據頂(ding)面水平線(xian)量出(chu)吊筋加工尺寸，若頂(ding)面平整較差，吊桿(gan)(gan)長度(du)不(bu)能統(tong)一時(shi)可(ke)拉通(tong)線(xian)，按(an)實際尺寸逐(zhu)—·找出(chu)吊桿(gan)(gan)長度(du)，吊桿(gan)(gan)可(ke)采取兩節搭(da)接(jie)(焊(han)接(jie))方式，搭(da)接(jie)長度(du)大于吊桿(gan)(gan)直徑的8倍，將吊桿(gan)(gan)下端套(tao)(tao)扣(kou)(kou)(套(tao)(tao)絲(si)時(shi)應加機油，以保證(zheng)套(tao)(tao)扣(kou)(kou)質量)套(tao)(tao)絲(si)長度(du)不(bu)小于50mm，然后將吊桿(gan)(gan)與角鐵吊件焊(han)接(jie)，焊(han)接(jie)要精心操作，不(bu)得馬(ma)虎，焊(han)接(jie)部位(wei)應飽滿(man)，確(que)保足夠的強度(du)。

c.角鐵(tie)吊(diao)件及吊(diao)桿加工(gong)完成后(hou)，按頂面水平線，付龍(long)骨(gu)底面拉通線，為吊(diao)桿安(an)(an)裝基準線，進行吊(diao)桿安(an)(an)裝，吊(diao)桿間距應均勻，靠墻邊吊(diao)桿距墻不得(de)大于200mm，安(an)(an)裝后(hou)的(de)吊(diao)桿應垂直并在一(yi)條(tiao)線上，刷防銹(xiu)漆兩遍，應按設(she)計要求調整起拱高度(起拱按短(duan)向跨(kua)度的(de)3-5/1000)。

d.吊(diao)(diao)(diao)桿(gan)距主(zhu)龍骨端部(bu)距離不得大于(yu)300mm，當大于(yu)300mm時應(ying)增加吊(diao)(diao)(diao)桿(gan)。當吊(diao)(diao)(diao)桿(gan)與(yu)設備相遇(yu)時，應(ying)調整并增設吊(diao)(diao)(diao)桿(gan)，并不得與(yu)設備共用吊(diao)(diao)(diao)桿(gan)。

步驟四：龍骨安裝：主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)應(ying)頂(ding)住(zhu)墻面(mian)，副(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)應(ying)緊貼(tie)墻面(mian)。用(yong)(yong)吊(diao)(diao)件(jian)(jian)與主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)連(lian)接(jie)(jie)(jie)(jie)，同(tong)時擰緊吊(diao)(diao)件(jian)(jian)螺母，使主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)安裝牢固(gu)(gu)，主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)連(lian)接(jie)(jie)(jie)(jie)件(jian)(jian)要錯位安裝以(yi)保證(zheng)有(you)足夠的穩定(ding)性。大面(mian)積(ji)(ji)吊(diao)(diao)頂(ding)每(mei)隔12m在主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)上(shang)(shang)部焊(han)接(jie)(jie)(jie)(jie)橫撐大龍(long)(long)(long)骨(gu)(gu)(gu)(gu)一道(dao)，以(yi)加(jia)強主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)側面(mian)穩定(ding)性及吊(diao)(diao)頂(ding)的整體性。付(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)安裝用(yong)(yong)吊(diao)(diao)掛(gua)(件(jian)(jian))與主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)固(gu)(gu)定(ding)，吊(diao)(diao)掛(gua)必須用(yong)(yong)鉗子夾緊使付(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)緊貼(tie)主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)，大面(mian)積(ji)(ji)或(huo)上(shang)(shang)人吊(diao)(diao)頂(ding)間(jian)(jian)距(ju)300mm，一般(ban)吊(diao)(diao)頂(ding)的間(jian)(jian)距(ju)401mm(己考慮石膏(gao)板留(liu)3mm縫隙(xi))，橫撐付(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)間(jian)(jian)距(ju)1500mm，用(yong)(yong)于(yu)石膏(gao)板中(zhong)間(jian)(jian)及寬邊(1200mm)接(jie)(jie)(jie)(jie)頭(tou)處、平行于(yu)主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)用(yong)(yong)支托與付(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)連(lian)接(jie)(jie)(jie)(jie)固(gu)(gu)定(ding)。

步驟五：安裝石膏板：先(xian)檢查龍骨(gu)(gu)安裝(zhuang)(zhuang)是(shi)(shi)否平(ping)整，牢(lao)固，配件安裝(zhuang)(zhuang)是(shi)(shi)否正確，然后才可(ke)進行石膏板(ban)(ban)(ban)安裝(zhuang)(zhuang)，首先(xian)根據(ju)龍骨(gu)(gu)間(jian)距(ju)在石膏板(ban)(ban)(ban)面上彈(dan)出龍骨(gu)(gu)中心(xin)(xin)線，一般先(xian)從頂棚中心(xin)(xin)向周(zhou)圍鋪(pu)設，固定石膏板(ban)(ban)(ban)的高強(qiang)自攻(gong)絲間(jian)距(ju)不(bu)大于150--170mm，由板(ban)(ban)(ban)中間(jian)向四(si)周(zhou)固定，強(qiang)攻(gong)絲距(ju)板(ban)(ban)(ban)長邊(bian)(bian)10--15mm，短邊(bian)(bian)15--20mm，沉入板(ban)(ban)(ban)內1-2mm不(bu)得(de)損壞(huai)紙面，應(ying)注意留3mm板(ban)(ban)(ban)縫(feng)(1200短邊(bian)(bian)留4--6mm縫(feng))，四(si)周(zhou)墻邊(bian)(bian)留10mm左(zuo)右縫(feng)隙以防伸縮變(bian)形，應(ying)錯位(錯開半板(ban)(ban)(ban))安裝(zhuang)(zhuang)。

步驟六：按質量要求及檢查方法檢查：

a.輕鋼龍骨安裝(zhuang)位置正確，牢(lao)固，無松動，吊桿做(zuo)防銹處理。

b.石膏板應表(biao)面平整無污染，反銹，無脫層、翹曲(qu)、折裂等缺陷。
