輕鋼龍骨(gu)石膏板天(tian)花(hua)吊(diao)頂(ding)施工(gong)(gong)工(gong)(gong)藝 打造時(shi)尚美觀天(tian)花(hua)

步驟一：清理現場：對(dui)施(shi)工現場墻、地(di)面、灰塵、垃圾進行清(qing)理。

步驟二：彈線定位：根據設(she)(she)計及(ji)現場要求、確定50cm水平(ping)線(xian)，用尺量(liang)至(zhi)頂(ding)(ding)面(mian)(mian)設(she)(she)計標高線(xian)，在四周墻面(mian)(mian)彈(dan)頂(ding)(ding)面(mian)(mian)水平(ping)線(xian)(水平(ping)線(xian)應以付(fu)龍骨底面(mian)(mian)為準)，然后(hou)畫出龍骨位置線(xian)和吊點(dian)(桿)布置線(xian)。

步驟三：安裝吊桿

a.角鐵(tie)吊(diao)(diao)(diao)(diao)(diao)件及吊(diao)(diao)(diao)(diao)(diao)筋(jin)加工：角鐵(tie)吊(diao)(diao)(diao)(diao)(diao)件采(cai)(cai)用L30*30角鐵(tie)加工，在角鐵(tie)面(mian)(mian)上劃出中心線，對應打(da)出一排 10或(huo) 8的孔、孔距(ju)(ju)45mm左(zuo)右，再(zai)將(jiang)角鐵(tie)分(fen)段切割下(xia)來(lai)。不(bu)上人(ren)吊(diao)(diao)(diao)(diao)(diao)件可用小角鐵(tie)制作， 吊(diao)(diao)(diao)(diao)(diao)點(dian)應在屋面(mian)(mian)板下(xia)均勻分(fen)布(施工前(qian)應對現(xian)場(chang)進行檢查，布點(dian)應避(bi)開頂(ding)面(mian)(mian)空調風筒及各種(zhong)管(guan)道(dao)，若(ruo)避(bi)不(bu)開時可采(cai)(cai)取角鐵(tie)補充吊(diao)(diao)(diao)(diao)(diao)點(dian))，大面(mian)(mian)積或(huo)上人(ren)吊(diao)(diao)(diao)(diao)(diao)頂(ding)吊(diao)(diao)(diao)(diao)(diao)點(dian)間距(ju)(ju)為(wei)≤1000mm，一般吊(diao)(diao)(diao)(diao)(diao)頂(ding)的吊(diao)(diao)(diao)(diao)(diao)點(dian)間距(ju)(ju)為(wei)≤1200mm，用電錘在頂(ding)上打(da)孔，放置膨脹栓(shuan)擰緊(jin)固定(ding)于(yu)頂(ding)面(mian)(mian)上。

b.根(gen)據頂面水平線量(liang)出(chu)吊(diao)(diao)筋加工(gong)尺寸，若(ruo)頂面平整(zheng)較差，吊(diao)(diao)桿長(chang)(chang)度(du)(du)不能統一時可拉通線，按實際尺寸逐—·找出(chu)吊(diao)(diao)桿長(chang)(chang)度(du)(du)，吊(diao)(diao)桿可采取兩節搭接(焊接)方式，搭接長(chang)(chang)度(du)(du)大于(yu)吊(diao)(diao)桿直(zhi)徑的8倍，將吊(diao)(diao)桿下(xia)端(duan)套(tao)扣(kou)(套(tao)絲時應(ying)加機油，以保(bao)證套(tao)扣(kou)質量(liang))套(tao)絲長(chang)(chang)度(du)(du)不小于(yu)50mm，然(ran)后將吊(diao)(diao)桿與角鐵吊(diao)(diao)件焊接，焊接要精(jing)心操作，不得馬虎，焊接部(bu)位應(ying)飽滿(man)，確保(bao)足(zu)夠的強度(du)(du)。

c.角鐵吊(diao)(diao)(diao)件及吊(diao)(diao)(diao)桿(gan)加工完成后(hou)(hou)，按(an)頂面水平線，付龍骨底面拉通線，為吊(diao)(diao)(diao)桿(gan)安裝(zhuang)基準線，進行吊(diao)(diao)(diao)桿(gan)安裝(zhuang)，吊(diao)(diao)(diao)桿(gan)間距(ju)應(ying)(ying)均勻，靠墻邊吊(diao)(diao)(diao)桿(gan)距(ju)墻不(bu)得(de)大于200mm，安裝(zhuang)后(hou)(hou)的吊(diao)(diao)(diao)桿(gan)應(ying)(ying)垂直并在一條線上，刷防(fang)銹漆(qi)兩遍，應(ying)(ying)按(an)設計要(yao)求調整起拱高度(du)(起拱按(an)短(duan)向(xiang)跨度(du)的3-5/1000)。

d.吊(diao)桿(gan)(gan)距(ju)主龍(long)骨端部距(ju)離不得(de)(de)大(da)于(yu)300mm，當大(da)于(yu)300mm時應(ying)增加吊(diao)桿(gan)(gan)。當吊(diao)桿(gan)(gan)與設(she)備(bei)相遇(yu)時，應(ying)調整并增設(she)吊(diao)桿(gan)(gan)，并不得(de)(de)與設(she)備(bei)共用吊(diao)桿(gan)(gan)。

步驟四：龍骨安裝：主龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)應(ying)頂住墻(qiang)面(mian)，副龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)應(ying)緊貼墻(qiang)面(mian)。用(yong)(yong)吊(diao)(diao)件與主龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)連接，同時擰(ning)緊吊(diao)(diao)件螺(luo)母，使(shi)主龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)安(an)裝(zhuang)(zhuang)牢固，主龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)連接件要(yao)錯位安(an)裝(zhuang)(zhuang)以(yi)保證有足夠的(de)穩(wen)(wen)定(ding)性(xing)。大面(mian)積吊(diao)(diao)頂每隔12m在主龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)上(shang)部(bu)焊接橫撐大龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)一(yi)道，以(yi)加強主龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)側面(mian)穩(wen)(wen)定(ding)性(xing)及吊(diao)(diao)頂的(de)整(zheng)體(ti)性(xing)。付(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)安(an)裝(zhuang)(zhuang)用(yong)(yong)吊(diao)(diao)掛(件)與主龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)固定(ding)，吊(diao)(diao)掛必(bi)須用(yong)(yong)鉗子夾緊使(shi)付(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)緊貼主龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)，大面(mian)積或上(shang)人(ren)吊(diao)(diao)頂間(jian)距300mm，一(yi)般吊(diao)(diao)頂的(de)間(jian)距401mm(己(ji)考慮石(shi)(shi)膏板留3mm縫隙(xi))，橫撐付(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)間(jian)距1500mm，用(yong)(yong)于(yu)石(shi)(shi)膏板中間(jian)及寬邊(1200mm)接頭處(chu)、平(ping)行于(yu)主龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)用(yong)(yong)支托與付(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)連接固定(ding)。

步驟五：安裝石膏板：先(xian)檢查(cha)龍骨(gu)安(an)裝是(shi)否平整，牢固，配件(jian)安(an)裝是(shi)否正確，然(ran)后(hou)才可進行石膏(gao)板(ban)(ban)(ban)安(an)裝，首先(xian)根據龍骨(gu)間(jian)距在石膏(gao)板(ban)(ban)(ban)面上彈出(chu)龍骨(gu)中(zhong)(zhong)心(xin)線(xian)，一般先(xian)從頂棚中(zhong)(zhong)心(xin)向周圍(wei)鋪設(she)，固定石膏(gao)板(ban)(ban)(ban)的高強自攻(gong)絲(si)間(jian)距不(bu)大于150--170mm，由板(ban)(ban)(ban)中(zhong)(zhong)間(jian)向四周固定，強攻(gong)絲(si)距板(ban)(ban)(ban)長邊10--15mm，短邊15--20mm，沉入(ru)板(ban)(ban)(ban)內1-2mm不(bu)得損(sun)壞紙面，應(ying)注意(yi)留(liu)3mm板(ban)(ban)(ban)縫(1200短邊留(liu)4--6mm縫)，四周墻邊留(liu)10mm左右縫隙以防伸縮(suo)變形(xing)，應(ying)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(qing)鋼龍(long)骨(gu)安(an)裝位置正確，牢固，無松動，吊(diao)桿做防銹處理(li)。

b.石膏板應表面平整無(wu)污染，反銹，無(wu)脫層、翹曲、折(zhe)裂等缺陷。
