輕鋼龍骨石(shi)膏板(ban)天花吊頂施工工藝 打(da)造時尚美觀(guan)天花

步驟一：清理現場：對施(shi)工現(xian)場墻、地(di)面、灰塵、垃圾進行清理。

步驟二：彈線定位：根據設(she)計及現場要求、確定50cm水(shui)平(ping)線，用尺量至頂面設(she)計標(biao)高(gao)線，在四(si)周(zhou)墻面彈頂面水(shui)平(ping)線(水(shui)平(ping)線應以付龍骨底面為(wei)準)，然后畫出(chu)龍骨位置線和吊點(桿)布置線。

步驟三：安裝吊桿

a.角(jiao)(jiao)鐵(tie)(tie)吊(diao)件及吊(diao)筋(jin)加工：角(jiao)(jiao)鐵(tie)(tie)吊(diao)件采用(yong)L30*30角(jiao)(jiao)鐵(tie)(tie)加工，在角(jiao)(jiao)鐵(tie)(tie)面(mian)(mian)上(shang)(shang)劃(hua)出中心線，對(dui)應(ying)(ying)打出一(yi)排 10或 8的孔、孔距(ju)45mm左(zuo)右，再將角(jiao)(jiao)鐵(tie)(tie)分段切割下(xia)來。不(bu)上(shang)(shang)人(ren)吊(diao)件可用(yong)小角(jiao)(jiao)鐵(tie)(tie)制作， 吊(diao)點應(ying)(ying)在屋面(mian)(mian)板下(xia)均勻分布(施工前應(ying)(ying)對(dui)現(xian)場(chang)進行檢查，布點應(ying)(ying)避開(kai)(kai)頂(ding)面(mian)(mian)空調風(feng)筒及各種管(guan)道，若避不(bu)開(kai)(kai)時可采取角(jiao)(jiao)鐵(tie)(tie)補充吊(diao)點)，大面(mian)(mian)積或上(shang)(shang)人(ren)吊(diao)頂(ding)吊(diao)點間距(ju)為(wei)≤1000mm，一(yi)般吊(diao)頂(ding)的吊(diao)點間距(ju)為(wei)≤1200mm，用(yong)電錘(chui)在頂(ding)上(shang)(shang)打孔，放(fang)置膨脹栓擰緊(jin)固定于頂(ding)面(mian)(mian)上(shang)(shang)。

b.根(gen)據頂面水平線(xian)量(liang)出吊(diao)(diao)筋加(jia)(jia)工尺(chi)寸，若頂面平整較差，吊(diao)(diao)桿長度(du)(du)不能(neng)統(tong)一時可(ke)(ke)拉通線(xian)，按實(shi)際(ji)尺(chi)寸逐—·找出吊(diao)(diao)桿長度(du)(du)，吊(diao)(diao)桿可(ke)(ke)采取兩節搭接(焊接)方(fang)式，搭接長度(du)(du)大于吊(diao)(diao)桿直徑(jing)的8倍，將吊(diao)(diao)桿下端(duan)套(tao)扣(套(tao)絲時應加(jia)(jia)機油，以(yi)保證套(tao)扣質量(liang))套(tao)絲長度(du)(du)不小(xiao)于50mm，然后將吊(diao)(diao)桿與角鐵吊(diao)(diao)件(jian)焊接，焊接要(yao)精心操(cao)作，不得馬虎，焊接部位應飽滿，確(que)保足夠(gou)的強(qiang)度(du)(du)。

c.角(jiao)鐵吊件及吊桿(gan)(gan)加工完成后，按頂面(mian)(mian)水平線，付(fu)龍骨底(di)面(mian)(mian)拉(la)通(tong)線，為吊桿(gan)(gan)安(an)裝基準(zhun)線，進行吊桿(gan)(gan)安(an)裝，吊桿(gan)(gan)間距(ju)應(ying)均(jun)勻，靠(kao)墻(qiang)邊吊桿(gan)(gan)距(ju)墻(qiang)不得(de)大(da)于200mm，安(an)裝后的(de)吊桿(gan)(gan)應(ying)垂(chui)直并在一條線上，刷防銹(xiu)漆兩(liang)遍，應(ying)按設計要(yao)求(qiu)調整起拱(gong)高度(du)(起拱(gong)按短向跨度(du)的(de)3-5/1000)。

d.吊(diao)(diao)桿距主龍骨端部距離不得(de)大(da)于300mm，當大(da)于300mm時應增加吊(diao)(diao)桿。當吊(diao)(diao)桿與設備相(xiang)遇時，應調整并增設吊(diao)(diao)桿，并不得(de)與設備共用(yong)吊(diao)(diao)桿。

步驟四：龍骨安裝：主龍(long)(long)骨(gu)(gu)應(ying)頂住(zhu)墻面，副龍(long)(long)骨(gu)(gu)應(ying)緊(jin)貼(tie)墻面。用吊(diao)(diao)件(jian)(jian)與(yu)主龍(long)(long)骨(gu)(gu)連接，同時擰緊(jin)吊(diao)(diao)件(jian)(jian)螺母，使(shi)主龍(long)(long)骨(gu)(gu)安裝(zhuang)牢固(gu)，主龍(long)(long)骨(gu)(gu)連接件(jian)(jian)要錯位(wei)安裝(zhuang)以(yi)保證有足(zu)夠的穩定(ding)性(xing)(xing)。大(da)面積(ji)吊(diao)(diao)頂每隔12m在主龍(long)(long)骨(gu)(gu)上部焊(han)接橫撐(cheng)大(da)龍(long)(long)骨(gu)(gu)一(yi)道，以(yi)加強主龍(long)(long)骨(gu)(gu)側面穩定(ding)性(xing)(xing)及吊(diao)(diao)頂的整體性(xing)(xing)。付龍(long)(long)骨(gu)(gu)安裝(zhuang)用吊(diao)(diao)掛(件(jian)(jian))與(yu)主龍(long)(long)骨(gu)(gu)固(gu)定(ding)，吊(diao)(diao)掛必須(xu)用鉗子夾(jia)緊(jin)使(shi)付龍(long)(long)骨(gu)(gu)緊(jin)貼(tie)主龍(long)(long)骨(gu)(gu)，大(da)面積(ji)或上人吊(diao)(diao)頂間(jian)距300mm，一(yi)般吊(diao)(diao)頂的間(jian)距401mm(己考(kao)慮石膏(gao)板(ban)(ban)留3mm縫隙)，橫撐(cheng)付龍(long)(long)骨(gu)(gu)間(jian)距1500mm，用于石膏(gao)板(ban)(ban)中間(jian)及寬邊(1200mm)接頭處、平行于主龍(long)(long)骨(gu)(gu)用支(zhi)托與(yu)付龍(long)(long)骨(gu)(gu)連接固(gu)定(ding)。

步驟五：安裝石膏板：先(xian)檢查龍骨(gu)(gu)安(an)(an)(an)裝(zhuang)是否平(ping)整，牢固(gu)，配件安(an)(an)(an)裝(zhuang)是否正(zheng)確，然后才可進行石(shi)(shi)膏板(ban)安(an)(an)(an)裝(zhuang)，首先(xian)根據龍骨(gu)(gu)間距(ju)在石(shi)(shi)膏板(ban)面上彈出(chu)龍骨(gu)(gu)中(zhong)心線(xian)，一(yi)般先(xian)從頂棚中(zhong)心向周圍(wei)鋪設，固(gu)定石(shi)(shi)膏板(ban)的高強自攻(gong)絲(si)間距(ju)不大于150--170mm，由板(ban)中(zhong)間向四周固(gu)定，強攻(gong)絲(si)距(ju)板(ban)長邊10--15mm，短邊15--20mm，沉入板(ban)內1-2mm不得損壞紙面，應(ying)注(zhu)意留3mm板(ban)縫(1200短邊留4--6mm縫)，四周墻邊留10mm左(zuo)右縫隙以防伸縮變形(xing)，應(ying)錯位(錯開半板(ban))安(an)(an)(an)裝(zhuang)。

步驟六：按質量要求及檢查方法檢查：

a.輕鋼(gang)龍(long)骨安(an)裝(zhuang)位置正確，牢固，無松動，吊桿做防銹處理。

b.石膏(gao)板應表面平整無污染，反(fan)銹，無脫層、翹曲、折裂等缺陷。
