步驟一：清理現場：對施工現場墻(qiang)、地面、灰塵、垃(la)圾進行(xing)清理。

步驟二：彈線定位：根(gen)據設計及(ji)現場要求、確定50cm水平線(xian)，用尺量至頂(ding)面(mian)設計標高線(xian)，在四周墻面(mian)彈(dan)頂(ding)面(mian)水平線(xian)(水平線(xian)應以付龍骨底(di)面(mian)為(wei)準)，然后畫出(chu)龍骨位(wei)置線(xian)和(he)吊點(桿(gan))布置線(xian)。

步驟三：安裝吊桿

a.角(jiao)(jiao)(jiao)鐵(tie)吊(diao)(diao)件及吊(diao)(diao)筋(jin)加(jia)工：角(jiao)(jiao)(jiao)鐵(tie)吊(diao)(diao)件采用(yong)L30*30角(jiao)(jiao)(jiao)鐵(tie)加(jia)工，在(zai)(zai)角(jiao)(jiao)(jiao)鐵(tie)面(mian)上(shang)(shang)(shang)(shang)劃出中(zhong)心線(xian)，對應(ying)打出一(yi)(yi)排 10或 8的(de)孔、孔距45mm左右，再將角(jiao)(jiao)(jiao)鐵(tie)分段切割下來(lai)。不(bu)上(shang)(shang)(shang)(shang)人吊(diao)(diao)件可用(yong)小角(jiao)(jiao)(jiao)鐵(tie)制作， 吊(diao)(diao)點(dian)應(ying)在(zai)(zai)屋(wu)面(mian)板下均(jun)勻分布(bu)(施工前應(ying)對現場進行檢查，布(bu)點(dian)應(ying)避(bi)開頂(ding)(ding)面(mian)空調風(feng)筒(tong)及各種管道，若避(bi)不(bu)開時可采取角(jiao)(jiao)(jiao)鐵(tie)補充吊(diao)(diao)點(dian))，大面(mian)積或上(shang)(shang)(shang)(shang)人吊(diao)(diao)頂(ding)(ding)吊(diao)(diao)點(dian)間(jian)距為≤1000mm，一(yi)(yi)般(ban)吊(diao)(diao)頂(ding)(ding)的(de)吊(diao)(diao)點(dian)間(jian)距為≤1200mm，用(yong)電錘(chui)在(zai)(zai)頂(ding)(ding)上(shang)(shang)(shang)(shang)打孔，放置膨脹栓擰緊固定于(yu)頂(ding)(ding)面(mian)上(shang)(shang)(shang)(shang)。

b.根據頂(ding)面(mian)水平線量出吊(diao)(diao)筋加工尺(chi)寸，若頂(ding)面(mian)平整(zheng)較差，吊(diao)(diao)桿長(chang)(chang)度(du)不(bu)能(neng)統一時(shi)可拉通線，按(an)實際尺(chi)寸逐—·找出吊(diao)(diao)桿長(chang)(chang)度(du)，吊(diao)(diao)桿可采(cai)取兩節搭接(jie)(jie)(焊(han)接(jie)(jie))方(fang)式，搭接(jie)(jie)長(chang)(chang)度(du)大于吊(diao)(diao)桿直(zhi)徑的8倍，將吊(diao)(diao)桿下(xia)端套扣(套絲時(shi)應(ying)加機油，以(yi)保(bao)證(zheng)套扣質(zhi)量)套絲長(chang)(chang)度(du)不(bu)小(xiao)于50mm，然后將吊(diao)(diao)桿與角鐵吊(diao)(diao)件焊(han)接(jie)(jie)，焊(han)接(jie)(jie)要精心操作，不(bu)得馬虎，焊(han)接(jie)(jie)部位應(ying)飽滿，確保(bao)足夠的強(qiang)度(du)。

c.角鐵(tie)吊(diao)(diao)件及吊(diao)(diao)桿(gan)(gan)加工(gong)完成后(hou)，按頂面水(shui)平(ping)線，付龍骨底面拉(la)通線，為吊(diao)(diao)桿(gan)(gan)安(an)裝(zhuang)基準線，進(jin)行吊(diao)(diao)桿(gan)(gan)安(an)裝(zhuang)，吊(diao)(diao)桿(gan)(gan)間(jian)距應(ying)均(jun)勻，靠墻(qiang)邊吊(diao)(diao)桿(gan)(gan)距墻(qiang)不得大于200mm，安(an)裝(zhuang)后(hou)的吊(diao)(diao)桿(gan)(gan)應(ying)垂直并在一條線上，刷防(fang)銹漆兩遍，應(ying)按設計要(yao)求(qiu)調整(zheng)起(qi)拱高度(起(qi)拱按短向跨度的3-5/1000)。

d.吊(diao)桿距主龍(long)骨端部距離不得大于300mm，當(dang)大于300mm時(shi)應增加吊(diao)桿。當(dang)吊(diao)桿與設(she)備(bei)相遇時(shi)，應調整(zheng)并增設(she)吊(diao)桿，并不得與設(she)備(bei)共用吊(diao)桿。

步驟四：龍骨安裝：主龍(long)(long)(long)骨(gu)(gu)應(ying)頂住墻面，副龍(long)(long)(long)骨(gu)(gu)應(ying)緊(jin)貼墻面。用(yong)(yong)吊(diao)件與(yu)(yu)主龍(long)(long)(long)骨(gu)(gu)連(lian)接，同(tong)時擰緊(jin)吊(diao)件螺母(mu)，使主龍(long)(long)(long)骨(gu)(gu)安裝(zhuang)牢固(gu)(gu)，主龍(long)(long)(long)骨(gu)(gu)連(lian)接件要錯位安裝(zhuang)以(yi)保證有足夠的穩定(ding)(ding)性(xing)。大面積(ji)吊(diao)頂每隔12m在主龍(long)(long)(long)骨(gu)(gu)上部(bu)焊(han)接橫(heng)(heng)撐(cheng)大龍(long)(long)(long)骨(gu)(gu)一道，以(yi)加強主龍(long)(long)(long)骨(gu)(gu)側面穩定(ding)(ding)性(xing)及吊(diao)頂的整(zheng)體性(xing)。付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)安裝(zhuang)用(yong)(yong)吊(diao)掛(件)與(yu)(yu)主龍(long)(long)(long)骨(gu)(gu)固(gu)(gu)定(ding)(ding)，吊(diao)掛必須用(yong)(yong)鉗子夾(jia)緊(jin)使付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)緊(jin)貼主龍(long)(long)(long)骨(gu)(gu)，大面積(ji)或上人吊(diao)頂間(jian)距(ju)(ju)300mm，一般吊(diao)頂的間(jian)距(ju)(ju)401mm(己考(kao)慮石膏板留3mm縫隙)，橫(heng)(heng)撐(cheng)付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)間(jian)距(ju)(ju)1500mm，用(yong)(yong)于石膏板中間(jian)及寬邊(1200mm)接頭處、平行于主龍(long)(long)(long)骨(gu)(gu)用(yong)(yong)支托(tuo)與(yu)(yu)付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)連(lian)接固(gu)(gu)定(ding)(ding)。

步驟五：安裝石膏板：先(xian)檢查龍(long)骨安(an)裝是否平整，牢固，配(pei)件安(an)裝是否正確，然后(hou)才(cai)可進行石(shi)(shi)膏(gao)板(ban)(ban)(ban)安(an)裝，首先(xian)根據龍(long)骨間距(ju)(ju)在(zai)石(shi)(shi)膏(gao)板(ban)(ban)(ban)面上彈出(chu)龍(long)骨中(zhong)心線，一(yi)般先(xian)從頂棚中(zhong)心向周圍鋪設，固定石(shi)(shi)膏(gao)板(ban)(ban)(ban)的高強自攻(gong)絲(si)間距(ju)(ju)不大于150--170mm，由板(ban)(ban)(ban)中(zhong)間向四(si)周固定，強攻(gong)絲(si)距(ju)(ju)板(ban)(ban)(ban)長邊10--15mm，短邊15--20mm，沉入板(ban)(ban)(ban)內(nei)1-2mm不得損壞紙面，應注(zhu)意(yi)留3mm板(ban)(ban)(ban)縫(feng)(1200短邊留4--6mm縫(feng))，四(si)周墻邊留10mm左右縫(feng)隙以防伸縮(suo)變形，應錯(cuo)位(錯(cuo)開半板(ban)(ban)(ban))安(an)裝。

步驟六：按質量要求及檢查方法檢查：

a.輕鋼龍骨安(an)裝位(wei)置正確，牢固，無松動，吊桿做防(fang)銹處(chu)理。

b.石膏板應表面平整(zheng)無污染，反銹，無脫層、翹曲、折(zhe)裂等缺陷。
