輕鋼(gang)龍骨石膏板天花(hua)吊頂施工工藝 打造時尚(shang)美觀天花(hua)

步驟一：清理現場：對施工(gong)現場墻、地面、灰塵(chen)、垃圾(ji)進行(xing)清理(li)。

步驟二：彈線定位：根據(ju)設計及(ji)現場要求、確定50cm水平(ping)線，用尺量(liang)至頂面設計標高(gao)線，在(zai)四周墻面彈頂面水平(ping)線(水平(ping)線應以(yi)付龍(long)(long)骨底面為準)，然后畫(hua)出龍(long)(long)骨位置(zhi)線和吊(diao)點(dian)(桿)布置(zhi)線。

步驟三：安裝吊桿

a.角(jiao)(jiao)鐵吊(diao)件(jian)及(ji)(ji)吊(diao)筋加工：角(jiao)(jiao)鐵吊(diao)件(jian)采(cai)用(yong)L30*30角(jiao)(jiao)鐵加工，在(zai)角(jiao)(jiao)鐵面上(shang)(shang)劃(hua)出中心(xin)線(xian)，對(dui)應(ying)打出一(yi)排 10或 8的孔、孔距45mm左(zuo)右(you)，再將角(jiao)(jiao)鐵分段切割下(xia)來。不(bu)上(shang)(shang)人吊(diao)件(jian)可用(yong)小角(jiao)(jiao)鐵制作， 吊(diao)點(dian)(dian)應(ying)在(zai)屋面板下(xia)均勻(yun)分布(bu)(bu)(施工前應(ying)對(dui)現場(chang)進行檢(jian)查，布(bu)(bu)點(dian)(dian)應(ying)避(bi)開(kai)(kai)頂面空調風(feng)筒及(ji)(ji)各種管道(dao)，若避(bi)不(bu)開(kai)(kai)時可采(cai)取(qu)角(jiao)(jiao)鐵補充吊(diao)點(dian)(dian))，大面積或上(shang)(shang)人吊(diao)頂吊(diao)點(dian)(dian)間距為(wei)(wei)≤1000mm，一(yi)般吊(diao)頂的吊(diao)點(dian)(dian)間距為(wei)(wei)≤1200mm，用(yong)電錘在(zai)頂上(shang)(shang)打孔，放置膨脹栓擰緊(jin)固定于頂面上(shang)(shang)。

b.根據(ju)頂面(mian)水平線量出吊(diao)筋加(jia)工(gong)尺寸，若頂面(mian)平整較差，吊(diao)桿長度不(bu)(bu)能統(tong)一時(shi)(shi)可拉通線，按實際(ji)尺寸逐—·找出吊(diao)桿長度，吊(diao)桿可采(cai)取(qu)兩節搭(da)接(jie)(焊(han)接(jie))方式，搭(da)接(jie)長度大(da)于吊(diao)桿直徑(jing)的8倍(bei)，將吊(diao)桿下(xia)端套(tao)(tao)扣(kou)(套(tao)(tao)絲(si)時(shi)(shi)應加(jia)機油，以保(bao)證套(tao)(tao)扣(kou)質量)套(tao)(tao)絲(si)長度不(bu)(bu)小于50mm，然后將吊(diao)桿與角鐵吊(diao)件焊(han)接(jie)，焊(han)接(jie)要精心操(cao)作，不(bu)(bu)得馬(ma)虎，焊(han)接(jie)部位應飽(bao)滿(man)，確保(bao)足夠(gou)的強度。

c.角鐵吊(diao)(diao)件及吊(diao)(diao)桿(gan)加工(gong)完成后，按(an)(an)(an)頂(ding)面水(shui)平線(xian)(xian)，付(fu)龍(long)骨底面拉通線(xian)(xian)，為吊(diao)(diao)桿(gan)安裝基(ji)準(zhun)線(xian)(xian)，進行吊(diao)(diao)桿(gan)安裝，吊(diao)(diao)桿(gan)間距應均(jun)勻(yun)，靠墻邊吊(diao)(diao)桿(gan)距墻不得(de)大(da)于200mm，安裝后的(de)吊(diao)(diao)桿(gan)應垂直(zhi)并(bing)在一條線(xian)(xian)上，刷防銹(xiu)漆(qi)兩遍，應按(an)(an)(an)設計要求調整起拱(gong)高度(du)(起拱(gong)按(an)(an)(an)短向跨(kua)度(du)的(de)3-5/1000)。

d.吊桿(gan)距(ju)主龍骨端(duan)部距(ju)離不(bu)得大于300mm，當(dang)大于300mm時應(ying)增(zeng)加(jia)吊桿(gan)。當(dang)吊桿(gan)與設(she)備相(xiang)遇時，應(ying)調整(zheng)并增(zeng)設(she)吊桿(gan)，并不(bu)得與設(she)備共用(yong)吊桿(gan)。

步驟四：龍骨安裝：主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)應頂(ding)(ding)住墻面(mian)(mian)，副(fu)龍(long)(long)(long)骨(gu)(gu)應緊貼墻面(mian)(mian)。用(yong)吊(diao)件(jian)與(yu)主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)連(lian)(lian)接，同(tong)時擰緊吊(diao)件(jian)螺母，使主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)安裝(zhuang)牢固(gu)，主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)連(lian)(lian)接件(jian)要(yao)錯位安裝(zhuang)以保證有足(zu)夠的(de)穩(wen)定(ding)性(xing)。大面(mian)(mian)積吊(diao)頂(ding)(ding)每(mei)隔(ge)12m在主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)上部焊(han)接橫撐大龍(long)(long)(long)骨(gu)(gu)一(yi)道，以加強(qiang)主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)側面(mian)(mian)穩(wen)定(ding)性(xing)及吊(diao)頂(ding)(ding)的(de)整體性(xing)。付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)安裝(zhuang)用(yong)吊(diao)掛(件(jian))與(yu)主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)固(gu)定(ding)，吊(diao)掛必須(xu)用(yong)鉗子夾緊使付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)緊貼主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)，大面(mian)(mian)積或上人吊(diao)頂(ding)(ding)間(jian)距(ju)(ju)300mm，一(yi)般吊(diao)頂(ding)(ding)的(de)間(jian)距(ju)(ju)401mm(己考(kao)慮石(shi)(shi)膏(gao)板留3mm縫隙)，橫撐付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)間(jian)距(ju)(ju)1500mm，用(yong)于石(shi)(shi)膏(gao)板中間(jian)及寬邊(1200mm)接頭處、平行于主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)用(yong)支(zhi)托與(yu)付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)連(lian)(lian)接固(gu)定(ding)。

步驟五：安裝石膏板：先(xian)檢查(cha)龍骨安裝是否平整，牢固，配件安裝是否正確，然后才可(ke)進行石膏板(ban)安裝，首先(xian)根(gen)據龍骨間(jian)(jian)距(ju)(ju)(ju)在石膏板(ban)面(mian)(mian)上彈(dan)出(chu)龍骨中心線，一般先(xian)從頂棚中心向周(zhou)(zhou)圍(wei)鋪設，固定(ding)石膏板(ban)的高強自攻(gong)絲間(jian)(jian)距(ju)(ju)(ju)不大于150--170mm，由板(ban)中間(jian)(jian)向四(si)周(zhou)(zhou)固定(ding)，強攻(gong)絲距(ju)(ju)(ju)板(ban)長邊(bian)10--15mm，短邊(bian)15--20mm，沉入板(ban)內1-2mm不得損壞紙面(mian)(mian)，應(ying)注意留3mm板(ban)縫(feng)(1200短邊(bian)留4--6mm縫(feng))，四(si)周(zhou)(zhou)墻邊(bian)留10mm左(zuo)右縫(feng)隙(xi)以防伸縮變形，應(ying)錯位(錯開半板(ban))安裝。

步驟六：按質量要求及檢查方法檢查：

a.輕鋼(gang)龍(long)骨安(an)裝位置正確，牢固，無松(song)動(dong)，吊桿做防銹(xiu)處理。

b.石膏板應表面平整(zheng)無污染，反銹，無脫(tuo)層、翹(qiao)曲、折(zhe)裂等缺陷。
