輕鋼龍骨石(shi)膏板天(tian)花吊頂施工工藝 打造時(shi)尚美觀天(tian)花

步驟一：清理現場：對施工現場墻、地面、灰塵、垃圾進行清理。

步驟二：彈線定位：根(gen)據設(she)計及(ji)現場要(yao)求、確定50cm水平線(xian)，用尺量至頂面(mian)設(she)計標高線(xian)，在四(si)周墻(qiang)面(mian)彈(dan)頂面(mian)水平線(xian)(水平線(xian)應以付龍骨底面(mian)為準(zhun))，然后(hou)畫出(chu)龍骨位置線(xian)和吊點(桿)布置線(xian)。

步驟三：安裝吊桿

a.角(jiao)鐵(tie)吊(diao)(diao)(diao)件(jian)(jian)及吊(diao)(diao)(diao)筋加(jia)(jia)工(gong)(gong)：角(jiao)鐵(tie)吊(diao)(diao)(diao)件(jian)(jian)采用(yong)L30*30角(jiao)鐵(tie)加(jia)(jia)工(gong)(gong)，在(zai)角(jiao)鐵(tie)面(mian)(mian)上(shang)(shang)劃(hua)出中心線(xian)，對應(ying)打(da)(da)出一(yi)排 10或 8的(de)(de)孔(kong)、孔(kong)距45mm左右，再將角(jiao)鐵(tie)分段切割下來。不上(shang)(shang)人吊(diao)(diao)(diao)件(jian)(jian)可(ke)用(yong)小(xiao)角(jiao)鐵(tie)制(zhi)作， 吊(diao)(diao)(diao)點應(ying)在(zai)屋面(mian)(mian)板下均勻分布(施(shi)工(gong)(gong)前(qian)應(ying)對現場進行檢查(cha)，布點應(ying)避(bi)開(kai)頂(ding)面(mian)(mian)空調風筒及各種管道，若(ruo)避(bi)不開(kai)時可(ke)采取角(jiao)鐵(tie)補(bu)充吊(diao)(diao)(diao)點)，大面(mian)(mian)積或上(shang)(shang)人吊(diao)(diao)(diao)頂(ding)吊(diao)(diao)(diao)點間(jian)距為(wei)≤1000mm，一(yi)般吊(diao)(diao)(diao)頂(ding)的(de)(de)吊(diao)(diao)(diao)點間(jian)距為(wei)≤1200mm，用(yong)電錘在(zai)頂(ding)上(shang)(shang)打(da)(da)孔(kong)，放置(zhi)膨脹栓擰緊固定于(yu)頂(ding)面(mian)(mian)上(shang)(shang)。

b.根據(ju)頂(ding)面水(shui)平線量(liang)出吊(diao)(diao)筋加工尺(chi)寸，若頂(ding)面平整較差(cha)，吊(diao)(diao)桿長度(du)(du)不能統一時可拉通線，按實際尺(chi)寸逐—·找出吊(diao)(diao)桿長度(du)(du)，吊(diao)(diao)桿可采取兩節搭(da)接(jie)(焊(han)(han)接(jie))方(fang)式，搭(da)接(jie)長度(du)(du)大于(yu)吊(diao)(diao)桿直徑的8倍，將吊(diao)(diao)桿下端套(tao)扣(kou)(套(tao)絲時應(ying)加機油，以保證套(tao)扣(kou)質量(liang))套(tao)絲長度(du)(du)不小于(yu)50mm，然后將吊(diao)(diao)桿與角(jiao)鐵吊(diao)(diao)件焊(han)(han)接(jie)，焊(han)(han)接(jie)要(yao)精心操作(zuo)，不得馬虎，焊(han)(han)接(jie)部位應(ying)飽(bao)滿(man)，確保足夠(gou)的強(qiang)度(du)(du)。

c.角鐵吊(diao)(diao)件及吊(diao)(diao)桿(gan)加工完成后(hou)(hou)，按(an)頂面水平線(xian)，付(fu)龍骨底面拉(la)通(tong)線(xian)，為吊(diao)(diao)桿(gan)安(an)裝基準(zhun)線(xian)，進行(xing)吊(diao)(diao)桿(gan)安(an)裝，吊(diao)(diao)桿(gan)間距(ju)應(ying)均勻，靠(kao)墻邊(bian)吊(diao)(diao)桿(gan)距(ju)墻不(bu)得大于200mm，安(an)裝后(hou)(hou)的吊(diao)(diao)桿(gan)應(ying)垂直(zhi)并在一條線(xian)上，刷防銹(xiu)漆兩遍(bian)，應(ying)按(an)設計要求調(diao)整起拱(gong)高度(起拱(gong)按(an)短向(xiang)跨度的3-5/1000)。

d.吊(diao)(diao)桿(gan)距主龍骨端部距離不得大于300mm，當(dang)大于300mm時應增加吊(diao)(diao)桿(gan)。當(dang)吊(diao)(diao)桿(gan)與設備相(xiang)遇時，應調整并(bing)增設吊(diao)(diao)桿(gan)，并(bing)不得與設備共用吊(diao)(diao)桿(gan)。

步驟四：龍骨安裝：主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)應頂(ding)(ding)(ding)住墻面(mian)，副(fu)龍(long)(long)(long)骨(gu)應緊(jin)(jin)(jin)貼墻面(mian)。用(yong)吊(diao)(diao)件與(yu)主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)連接(jie)，同時擰緊(jin)(jin)(jin)吊(diao)(diao)件螺母，使主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)安裝(zhuang)牢固，主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)連接(jie)件要錯位(wei)安裝(zhuang)以保(bao)證(zheng)有足夠的(de)穩定(ding)(ding)性。大面(mian)積(ji)(ji)吊(diao)(diao)頂(ding)(ding)(ding)每隔12m在主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)上(shang)部(bu)焊接(jie)橫撐大龍(long)(long)(long)骨(gu)一道，以加強主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)側面(mian)穩定(ding)(ding)性及吊(diao)(diao)頂(ding)(ding)(ding)的(de)整體性。付(fu)龍(long)(long)(long)骨(gu)安裝(zhuang)用(yong)吊(diao)(diao)掛(件)與(yu)主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)固定(ding)(ding)，吊(diao)(diao)掛必須用(yong)鉗子夾緊(jin)(jin)(jin)使付(fu)龍(long)(long)(long)骨(gu)緊(jin)(jin)(jin)貼主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)，大面(mian)積(ji)(ji)或上(shang)人吊(diao)(diao)頂(ding)(ding)(ding)間距(ju)(ju)300mm，一般吊(diao)(diao)頂(ding)(ding)(ding)的(de)間距(ju)(ju)401mm(己考慮石(shi)膏板留3mm縫(feng)隙)，橫撐付(fu)龍(long)(long)(long)骨(gu)間距(ju)(ju)1500mm，用(yong)于石(shi)膏板中間及寬邊(bian)(1200mm)接(jie)頭處、平(ping)行于主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)用(yong)支(zhi)托與(yu)付(fu)龍(long)(long)(long)骨(gu)連接(jie)固定(ding)(ding)。

步驟五：安裝石膏板：先(xian)檢查龍骨(gu)安(an)裝(zhuang)是(shi)否平整，牢固，配件(jian)安(an)裝(zhuang)是(shi)否正確(que)，然(ran)后才可進行(xing)石膏板(ban)(ban)安(an)裝(zhuang)，首先(xian)根(gen)據(ju)龍骨(gu)間距在石膏板(ban)(ban)面(mian)上彈出龍骨(gu)中心(xin)線，一般(ban)先(xian)從(cong)頂棚中心(xin)向周(zhou)圍鋪設，固定石膏板(ban)(ban)的高強(qiang)(qiang)自攻(gong)絲間距不(bu)大于150--170mm，由板(ban)(ban)中間向四(si)(si)周(zhou)固定，強(qiang)(qiang)攻(gong)絲距板(ban)(ban)長邊10--15mm，短邊15--20mm，沉入板(ban)(ban)內1-2mm不(bu)得損(sun)壞紙面(mian)，應注意留3mm板(ban)(ban)縫(feng)(1200短邊留4--6mm縫(feng))，四(si)(si)周(zhou)墻邊留10mm左右縫(feng)隙以(yi)防伸縮(suo)變形，應錯(cuo)位(wei)(錯(cuo)開半(ban)板(ban)(ban))安(an)裝(zhuang)。

步驟六：按質量要求及檢查方法檢查：

a.輕(qing)鋼(gang)龍骨安裝位(wei)置正確，牢(lao)固，無(wu)松動，吊桿做防(fang)銹處理。

b.石膏板應表面平整無污染，反銹(xiu)，無脫層、翹曲、折裂等缺陷。
