輕鋼龍骨石膏板天花(hua)吊頂施工工藝 打造時尚美觀天花(hua)

步驟一：清理現場：對施工現場墻、地(di)面、灰塵、垃圾進(jin)行(xing)清理。

步驟二：彈線定位：根據設(she)計(ji)及現場(chang)要求、確(que)定50cm水(shui)平線(xian)，用尺(chi)量(liang)至頂(ding)面設(she)計(ji)標高(gao)線(xian)，在(zai)四(si)周墻面彈頂(ding)面水(shui)平線(xian)(水(shui)平線(xian)應以付(fu)龍(long)(long)骨底面為(wei)準)，然后畫出龍(long)(long)骨位置(zhi)線(xian)和(he)吊點(桿)布置(zhi)線(xian)。

步驟三：安裝吊桿

a.角(jiao)鐵(tie)吊(diao)(diao)(diao)件(jian)及吊(diao)(diao)(diao)筋加(jia)工：角(jiao)鐵(tie)吊(diao)(diao)(diao)件(jian)采(cai)(cai)用L30*30角(jiao)鐵(tie)加(jia)工，在角(jiao)鐵(tie)面(mian)(mian)(mian)上(shang)劃出(chu)中心(xin)線，對(dui)應(ying)打出(chu)一(yi)排 10或 8的孔(kong)、孔(kong)距45mm左右(you)，再將角(jiao)鐵(tie)分(fen)段(duan)切割下來。不上(shang)人吊(diao)(diao)(diao)件(jian)可用小角(jiao)鐵(tie)制作， 吊(diao)(diao)(diao)點(dian)(dian)應(ying)在屋(wu)面(mian)(mian)(mian)板下均勻(yun)分(fen)布(施工前應(ying)對(dui)現場進(jin)行(xing)檢查，布點(dian)(dian)應(ying)避開頂面(mian)(mian)(mian)空調風筒及各種管道(dao)，若避不開時可采(cai)(cai)取(qu)角(jiao)鐵(tie)補(bu)充吊(diao)(diao)(diao)點(dian)(dian))，大面(mian)(mian)(mian)積或上(shang)人吊(diao)(diao)(diao)頂吊(diao)(diao)(diao)點(dian)(dian)間距為≤1000mm，一(yi)般吊(diao)(diao)(diao)頂的吊(diao)(diao)(diao)點(dian)(dian)間距為≤1200mm，用電(dian)錘在頂上(shang)打孔(kong)，放置膨脹栓擰緊固定于頂面(mian)(mian)(mian)上(shang)。

b.根據(ju)頂面水平(ping)線(xian)量(liang)出吊(diao)筋加工尺寸，若頂面平(ping)整較差，吊(diao)桿(gan)長(chang)度(du)(du)不(bu)能統一時可拉通線(xian)，按實際尺寸逐(zhu)—·找出吊(diao)桿(gan)長(chang)度(du)(du)，吊(diao)桿(gan)可采(cai)取兩節(jie)搭(da)接(jie)(焊(han)接(jie))方(fang)式(shi)，搭(da)接(jie)長(chang)度(du)(du)大于(yu)吊(diao)桿(gan)直徑的(de)8倍，將(jiang)(jiang)吊(diao)桿(gan)下端套(tao)扣(套(tao)絲(si)時應加機油，以保證套(tao)扣質(zhi)量(liang))套(tao)絲(si)長(chang)度(du)(du)不(bu)小于(yu)50mm，然后(hou)將(jiang)(jiang)吊(diao)桿(gan)與角鐵吊(diao)件焊(han)接(jie)，焊(han)接(jie)要(yao)精心操作，不(bu)得馬虎，焊(han)接(jie)部位(wei)應飽(bao)滿，確(que)保足夠的(de)強度(du)(du)。

c.角鐵(tie)吊(diao)件及吊(diao)桿加工完成后，按頂面水平線(xian)(xian)，付龍(long)骨底面拉通線(xian)(xian)，為吊(diao)桿安(an)(an)裝(zhuang)基準(zhun)線(xian)(xian)，進(jin)行吊(diao)桿安(an)(an)裝(zhuang)，吊(diao)桿間距應均勻，靠(kao)墻(qiang)邊吊(diao)桿距墻(qiang)不(bu)得大于200mm，安(an)(an)裝(zhuang)后的(de)吊(diao)桿應垂(chui)直(zhi)并(bing)在一條(tiao)線(xian)(xian)上(shang)，刷防銹(xiu)漆兩遍(bian)，應按設計要求調整起(qi)拱高度(起(qi)拱按短(duan)向跨(kua)度的(de)3-5/1000)。

d.吊(diao)(diao)桿(gan)距主龍骨端部距離不(bu)(bu)得(de)大于(yu)300mm，當大于(yu)300mm時(shi)應增加吊(diao)(diao)桿(gan)。當吊(diao)(diao)桿(gan)與(yu)設(she)備(bei)相遇(yu)時(shi)，應調整并增設(she)吊(diao)(diao)桿(gan)，并不(bu)(bu)得(de)與(yu)設(she)備(bei)共用吊(diao)(diao)桿(gan)。

步驟四：龍骨安裝：主(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)應頂(ding)(ding)住墻(qiang)面(mian)，副龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)應緊貼墻(qiang)面(mian)。用(yong)吊件(jian)與主(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)連接，同時(shi)擰緊吊件(jian)螺母，使(shi)主(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)安(an)(an)裝牢固(gu)(gu)，主(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)連接件(jian)要錯位安(an)(an)裝以保證有足夠的(de)穩定(ding)性(xing)。大(da)(da)面(mian)積吊頂(ding)(ding)每隔12m在(zai)主(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)上(shang)部焊(han)接橫撐大(da)(da)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)一(yi)道，以加強主(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)側(ce)面(mian)穩定(ding)性(xing)及吊頂(ding)(ding)的(de)整體(ti)性(xing)。付(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)安(an)(an)裝用(yong)吊掛(gua)(件(jian))與主(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)固(gu)(gu)定(ding)，吊掛(gua)必須用(yong)鉗子夾(jia)緊使(shi)付(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)緊貼主(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)，大(da)(da)面(mian)積或上(shang)人吊頂(ding)(ding)間距(ju)300mm，一(yi)般吊頂(ding)(ding)的(de)間距(ju)401mm(己考慮石膏(gao)板(ban)留3mm縫隙)，橫撐付(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)間距(ju)1500mm，用(yong)于石膏(gao)板(ban)中(zhong)間及寬邊(1200mm)接頭處、平行于主(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)用(yong)支托與付(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)連接固(gu)(gu)定(ding)。

步驟五：安裝石膏板：先檢(jian)查(cha)龍骨(gu)(gu)安(an)裝(zhuang)是否平整，牢(lao)固(gu)(gu)，配件(jian)安(an)裝(zhuang)是否正確，然后(hou)才可(ke)進行石膏(gao)板(ban)(ban)安(an)裝(zhuang)，首先根(gen)據龍骨(gu)(gu)間距(ju)(ju)在石膏(gao)板(ban)(ban)面上彈出龍骨(gu)(gu)中(zhong)心線，一般先從(cong)頂棚(peng)中(zhong)心向周(zhou)圍(wei)鋪設，固(gu)(gu)定石膏(gao)板(ban)(ban)的高強自攻絲間距(ju)(ju)不大(da)于(yu)150--170mm，由板(ban)(ban)中(zhong)間向四周(zhou)固(gu)(gu)定，強攻絲距(ju)(ju)板(ban)(ban)長(chang)邊(bian)(bian)10--15mm，短邊(bian)(bian)15--20mm，沉入(ru)板(ban)(ban)內(nei)1-2mm不得損壞(huai)紙面，應(ying)注意留(liu)3mm板(ban)(ban)縫(1200短邊(bian)(bian)留(liu)4--6mm縫)，四周(zhou)墻邊(bian)(bian)留(liu)10mm左右縫隙以防伸縮變形，應(ying)錯(cuo)(cuo)位(錯(cuo)(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)鋼龍骨安裝位置(zhi)正確，牢(lao)固，無松動，吊桿做防銹處(chu)理。

b.石(shi)膏板應表面平整無(wu)污染，反銹(xiu)，無(wu)脫層、翹曲、折裂等缺(que)陷。
