輕鋼龍骨石膏板天花吊頂施工工藝(yi) 打造(zao)時尚美觀天花

步驟一：清理現場：對施工現場墻(qiang)、地面、灰塵、垃圾進行清理。

步驟二：彈線定位：根據(ju)設計及現場要求、確定50cm水平(ping)線(xian)，用(yong)尺(chi)量至頂面設計標高線(xian)，在四周墻面彈頂面水平(ping)線(xian)(水平(ping)線(xian)應(ying)以付(fu)龍(long)骨(gu)底面為準)，然(ran)后畫出(chu)龍(long)骨(gu)位置線(xian)和吊點(桿(gan))布(bu)置線(xian)。

步驟三：安裝吊桿

a.角(jiao)(jiao)鐵(tie)吊(diao)件(jian)及吊(diao)筋加工：角(jiao)(jiao)鐵(tie)吊(diao)件(jian)采用L30*30角(jiao)(jiao)鐵(tie)加工，在角(jiao)(jiao)鐵(tie)面(mian)上劃出(chu)中心線(xian)，對(dui)應(ying)打(da)出(chu)一排 10或 8的(de)孔(kong)(kong)、孔(kong)(kong)距45mm左(zuo)右，再將角(jiao)(jiao)鐵(tie)分段切割下(xia)來。不上人吊(diao)件(jian)可用小角(jiao)(jiao)鐵(tie)制作， 吊(diao)點(dian)(dian)應(ying)在屋面(mian)板下(xia)均勻(yun)分布(bu)(施(shi)工前應(ying)對(dui)現(xian)場(chang)進行檢查，布(bu)點(dian)(dian)應(ying)避(bi)開頂(ding)面(mian)空調風筒及各(ge)種(zhong)管道(dao)，若避(bi)不開時可采取角(jiao)(jiao)鐵(tie)補充(chong)吊(diao)點(dian)(dian))，大(da)面(mian)積或上人吊(diao)頂(ding)吊(diao)點(dian)(dian)間距為(wei)≤1000mm，一般(ban)吊(diao)頂(ding)的(de)吊(diao)點(dian)(dian)間距為(wei)≤1200mm，用電錘在頂(ding)上打(da)孔(kong)(kong)，放置(zhi)膨脹栓擰緊固定于頂(ding)面(mian)上。

b.根據(ju)頂(ding)面(mian)水平線量出(chu)吊(diao)(diao)(diao)筋加工(gong)尺(chi)寸，若頂(ding)面(mian)平整較差(cha)，吊(diao)(diao)(diao)桿(gan)(gan)長度(du)(du)不(bu)(bu)能(neng)統(tong)一(yi)時可拉通(tong)線，按實際(ji)尺(chi)寸逐—·找出(chu)吊(diao)(diao)(diao)桿(gan)(gan)長度(du)(du)，吊(diao)(diao)(diao)桿(gan)(gan)可采取兩節(jie)搭(da)(da)接(jie)(jie)(焊(han)接(jie)(jie))方式，搭(da)(da)接(jie)(jie)長度(du)(du)大(da)于吊(diao)(diao)(diao)桿(gan)(gan)直徑(jing)的8倍(bei)，將吊(diao)(diao)(diao)桿(gan)(gan)下端套(tao)扣(套(tao)絲時應(ying)加機油，以保證套(tao)扣質量)套(tao)絲長度(du)(du)不(bu)(bu)小于50mm，然后將吊(diao)(diao)(diao)桿(gan)(gan)與角鐵(tie)吊(diao)(diao)(diao)件焊(han)接(jie)(jie)，焊(han)接(jie)(jie)要精心操作，不(bu)(bu)得馬虎(hu)，焊(han)接(jie)(jie)部(bu)位應(ying)飽(bao)滿，確保足夠的強度(du)(du)。

c.角鐵吊(diao)(diao)件及吊(diao)(diao)桿(gan)加工完(wan)成后，按頂面水平線，付龍骨底面拉通線，為吊(diao)(diao)桿(gan)安裝基準線，進行吊(diao)(diao)桿(gan)安裝，吊(diao)(diao)桿(gan)間距應(ying)均勻，靠墻邊吊(diao)(diao)桿(gan)距墻不得(de)大于200mm，安裝后的(de)吊(diao)(diao)桿(gan)應(ying)垂直并在一條線上，刷防銹(xiu)漆兩(liang)遍，應(ying)按設計要求(qiu)調整起拱(gong)(gong)高度(起拱(gong)(gong)按短向跨度的(de)3-5/1000)。

d.吊(diao)桿(gan)(gan)距(ju)主龍骨端部(bu)距(ju)離不得大于300mm，當大于300mm時(shi)應(ying)(ying)增加吊(diao)桿(gan)(gan)。當吊(diao)桿(gan)(gan)與(yu)設備(bei)相遇時(shi)，應(ying)(ying)調整并增設吊(diao)桿(gan)(gan)，并不得與(yu)設備(bei)共(gong)用(yong)吊(diao)桿(gan)(gan)。

步驟四：龍骨安裝：主龍(long)(long)(long)骨應頂(ding)住墻面(mian)(mian)，副龍(long)(long)(long)骨應緊貼墻面(mian)(mian)。用(yong)吊件(jian)(jian)與(yu)主龍(long)(long)(long)骨連接，同時(shi)擰緊吊件(jian)(jian)螺(luo)母，使(shi)主龍(long)(long)(long)骨安裝牢固(gu)，主龍(long)(long)(long)骨連接件(jian)(jian)要錯位安裝以(yi)保證有足(zu)夠的穩(wen)定(ding)性(xing)。大面(mian)(mian)積吊頂(ding)每隔12m在主龍(long)(long)(long)骨上部(bu)焊接橫撐大龍(long)(long)(long)骨一道，以(yi)加強主龍(long)(long)(long)骨側面(mian)(mian)穩(wen)定(ding)性(xing)及吊頂(ding)的整體(ti)性(xing)。付龍(long)(long)(long)骨安裝用(yong)吊掛(gua)(件(jian)(jian))與(yu)主龍(long)(long)(long)骨固(gu)定(ding)，吊掛(gua)必須用(yong)鉗子夾(jia)緊使(shi)付龍(long)(long)(long)骨緊貼主龍(long)(long)(long)骨，大面(mian)(mian)積或上人(ren)吊頂(ding)間距300mm，一般吊頂(ding)的間距401mm(己考(kao)慮石膏板(ban)(ban)留(liu)3mm縫(feng)隙)，橫撐付龍(long)(long)(long)骨間距1500mm，用(yong)于石膏板(ban)(ban)中間及寬(kuan)邊(1200mm)接頭(tou)處(chu)、平(ping)行于主龍(long)(long)(long)骨用(yong)支托與(yu)付龍(long)(long)(long)骨連接固(gu)定(ding)。

步驟五：安裝石膏板：先(xian)檢查龍骨安裝是否平整(zheng)，牢(lao)固，配(pei)件安裝是否正(zheng)確，然后才可進行石(shi)膏板(ban)(ban)(ban)安裝，首(shou)先(xian)根據(ju)龍骨間距(ju)在石(shi)膏板(ban)(ban)(ban)面(mian)上彈(dan)出(chu)龍骨中(zhong)心線，一(yi)般(ban)先(xian)從頂棚中(zhong)心向周(zhou)圍鋪設，固定石(shi)膏板(ban)(ban)(ban)的(de)高(gao)強(qiang)自(zi)攻絲間距(ju)不大于150--170mm，由板(ban)(ban)(ban)中(zhong)間向四(si)周(zhou)固定，強(qiang)攻絲距(ju)板(ban)(ban)(ban)長邊(bian)10--15mm，短(duan)邊(bian)15--20mm，沉入板(ban)(ban)(ban)內(nei)1-2mm不得損壞紙(zhi)面(mian)，應(ying)注意留(liu)3mm板(ban)(ban)(ban)縫(1200短(duan)邊(bian)留(liu)4--6mm縫)，四(si)周(zhou)墻(qiang)邊(bian)留(liu)10mm左(zuo)右縫隙(xi)以防(fang)伸縮(suo)變(bian)形，應(ying)錯(cuo)位(錯(cuo)開半板(ban)(ban)(ban))安裝。

步驟六：按質量要求及檢查方法檢查：

a.輕(qing)鋼龍骨安裝位置正確，牢固(gu)，無松動，吊桿做防銹處理。

b.石膏板應(ying)表面平整無污染(ran)，反銹，無脫層、翹(qiao)曲、折裂等(deng)缺陷。
