步驟一：清理現場：對施工現(xian)場墻、地(di)面、灰(hui)塵、垃圾進行清理。

步驟二：彈線定位：根據設計(ji)及現場要求、確定50cm水(shui)平線(xian)，用尺量至頂(ding)面(mian)設計(ji)標高線(xian)，在(zai)四周墻(qiang)面(mian)彈(dan)頂(ding)面(mian)水(shui)平線(xian)(水(shui)平線(xian)應以(yi)付(fu)龍骨(gu)底面(mian)為準)，然后畫出龍骨(gu)位置(zhi)線(xian)和吊點(桿)布置(zhi)線(xian)。

步驟三：安裝吊桿

a.角鐵吊(diao)(diao)(diao)件及吊(diao)(diao)(diao)筋加工(gong)：角鐵吊(diao)(diao)(diao)件采用L30*30角鐵加工(gong)，在(zai)角鐵面上劃出中心(xin)線，對應打出一排 10或 8的(de)孔、孔距(ju)45mm左右(you)，再將角鐵分(fen)段切割(ge)下來(lai)。不(bu)(bu)上人吊(diao)(diao)(diao)件可用小角鐵制(zhi)作(zuo)， 吊(diao)(diao)(diao)點(dian)應在(zai)屋面板(ban)下均(jun)勻分(fen)布(施(shi)工(gong)前應對現場進(jin)行(xing)檢查，布點(dian)應避開頂(ding)(ding)面空調風筒(tong)及各種管道，若(ruo)避不(bu)(bu)開時可采取角鐵補充吊(diao)(diao)(diao)點(dian))，大面積或上人吊(diao)(diao)(diao)頂(ding)(ding)吊(diao)(diao)(diao)點(dian)間距(ju)為(wei)≤1000mm，一般(ban)吊(diao)(diao)(diao)頂(ding)(ding)的(de)吊(diao)(diao)(diao)點(dian)間距(ju)為(wei)≤1200mm，用電(dian)錘在(zai)頂(ding)(ding)上打孔，放置膨脹(zhang)栓(shuan)擰緊固定(ding)于頂(ding)(ding)面上。

b.根據(ju)頂面水平(ping)線量出(chu)吊(diao)(diao)(diao)筋加(jia)工尺寸(cun)，若頂面平(ping)整較差，吊(diao)(diao)(diao)桿(gan)(gan)長度(du)不能(neng)統一(yi)時(shi)可拉通線，按(an)實際尺寸(cun)逐(zhu)—·找(zhao)出(chu)吊(diao)(diao)(diao)桿(gan)(gan)長度(du)，吊(diao)(diao)(diao)桿(gan)(gan)可采取兩節搭接(jie)(焊(han)(han)(han)接(jie))方(fang)式，搭接(jie)長度(du)大(da)于吊(diao)(diao)(diao)桿(gan)(gan)直徑的8倍，將吊(diao)(diao)(diao)桿(gan)(gan)下(xia)端套(tao)扣(套(tao)絲時(shi)應加(jia)機油，以保(bao)證(zheng)套(tao)扣質(zhi)量)套(tao)絲長度(du)不小于50mm，然后將吊(diao)(diao)(diao)桿(gan)(gan)與角鐵吊(diao)(diao)(diao)件焊(han)(han)(han)接(jie)，焊(han)(han)(han)接(jie)要精心操作(zuo)，不得(de)馬虎，焊(han)(han)(han)接(jie)部位應飽滿，確保(bao)足夠的強度(du)。

c.角(jiao)鐵吊件及吊桿(gan)加(jia)工(gong)完成后(hou)，按(an)(an)頂面(mian)水平線，付龍骨底(di)面(mian)拉通線，為(wei)吊桿(gan)安裝基準(zhun)線，進行吊桿(gan)安裝，吊桿(gan)間距(ju)應均勻，靠墻(qiang)(qiang)邊(bian)吊桿(gan)距(ju)墻(qiang)(qiang)不得大(da)于(yu)200mm，安裝后(hou)的(de)吊桿(gan)應垂直(zhi)并在(zai)一條(tiao)線上，刷防銹(xiu)漆兩遍(bian)，應按(an)(an)設計要求(qiu)調整起拱(gong)高度(起拱(gong)按(an)(an)短(duan)向跨(kua)度的(de)3-5/1000)。

d.吊桿(gan)距主龍骨端部(bu)距離不得大于(yu)300mm，當(dang)大于(yu)300mm時應(ying)增(zeng)加(jia)吊桿(gan)。當(dang)吊桿(gan)與設備相遇時，應(ying)調整并(bing)增(zeng)設吊桿(gan)，并(bing)不得與設備共用吊桿(gan)。

步驟四：龍骨安裝：主(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)應(ying)頂(ding)住(zhu)墻(qiang)面(mian)，副龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)應(ying)緊(jin)(jin)(jin)貼(tie)墻(qiang)面(mian)。用(yong)(yong)吊(diao)(diao)(diao)件(jian)與主(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)連(lian)接，同時擰緊(jin)(jin)(jin)吊(diao)(diao)(diao)件(jian)螺母，使(shi)主(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)安裝牢固(gu)，主(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)連(lian)接件(jian)要錯位安裝以保證(zheng)有足夠(gou)的穩定(ding)性。大面(mian)積吊(diao)(diao)(diao)頂(ding)每隔12m在主(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)上(shang)(shang)部焊接橫撐大龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)一道，以加強主(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)側面(mian)穩定(ding)性及(ji)吊(diao)(diao)(diao)頂(ding)的整體性。付(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)安裝用(yong)(yong)吊(diao)(diao)(diao)掛(件(jian))與主(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)固(gu)定(ding)，吊(diao)(diao)(diao)掛必須(xu)用(yong)(yong)鉗子夾緊(jin)(jin)(jin)使(shi)付(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)緊(jin)(jin)(jin)貼(tie)主(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)，大面(mian)積或上(shang)(shang)人吊(diao)(diao)(diao)頂(ding)間(jian)距300mm，一般吊(diao)(diao)(diao)頂(ding)的間(jian)距401mm(己(ji)考慮(lv)石(shi)膏板留3mm縫隙)，橫撐付(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)間(jian)距1500mm，用(yong)(yong)于石(shi)膏板中間(jian)及(ji)寬邊(1200mm)接頭處、平行于主(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)用(yong)(yong)支托(tuo)與付(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)連(lian)接固(gu)定(ding)。

步驟五：安裝石膏板：先(xian)檢查龍骨安(an)(an)裝(zhuang)是否(fou)平整，牢(lao)固，配件安(an)(an)裝(zhuang)是否(fou)正確，然后才可(ke)進行石(shi)膏板(ban)(ban)(ban)安(an)(an)裝(zhuang)，首先(xian)根據龍骨間距在石(shi)膏板(ban)(ban)(ban)面(mian)上彈出龍骨中心線，一般先(xian)從頂棚中心向周(zhou)圍鋪設，固定(ding)石(shi)膏板(ban)(ban)(ban)的高強自(zi)攻絲(si)間距不大于150--170mm，由板(ban)(ban)(ban)中間向四(si)周(zhou)固定(ding)，強攻絲(si)距板(ban)(ban)(ban)長邊10--15mm，短邊15--20mm，沉入板(ban)(ban)(ban)內1-2mm不得損壞紙面(mian)，應(ying)注意留3mm板(ban)(ban)(ban)縫(1200短邊留4--6mm縫)，四(si)周(zhou)墻邊留10mm左右縫隙以防(fang)伸縮變形，應(ying)錯位(wei)(錯開(kai)半板(ban)(ban)(ban))安(an)(an)裝(zhuang)。

步驟六：按質量要求及檢查方法檢查：

a.輕鋼龍(long)骨安裝位置正確，牢固，無松動，吊桿做防(fang)銹(xiu)處理。

b.石(shi)膏板(ban)應表面平整無(wu)污染，反(fan)銹，無(wu)脫層、翹曲、折裂等缺陷(xian)。
