輕鋼(gang)龍骨石膏板天花(hua)吊頂施工工藝 打造(zao)時(shi)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)行清(qing)理。

步驟二：彈線定位：根據設(she)計及(ji)現場要求(qiu)、確定50cm水(shui)平線，用尺量至頂(ding)面(mian)設(she)計標高線，在四周(zhou)墻(qiang)面(mian)彈(dan)頂(ding)面(mian)水(shui)平線(水(shui)平線應以(yi)付龍骨底面(mian)為(wei)準(zhun))，然(ran)后畫出龍骨位(wei)置(zhi)線和吊點(桿(gan))布置(zhi)線。

步驟三：安裝吊桿

a.角(jiao)鐵(tie)(tie)吊(diao)件及吊(diao)筋加(jia)工(gong)：角(jiao)鐵(tie)(tie)吊(diao)件采用(yong)L30*30角(jiao)鐵(tie)(tie)加(jia)工(gong)，在(zai)角(jiao)鐵(tie)(tie)面上(shang)劃出(chu)中心線(xian)，對(dui)應打(da)出(chu)一排 10或 8的孔、孔距45mm左右，再將角(jiao)鐵(tie)(tie)分段切割下來。不(bu)上(shang)人(ren)吊(diao)件可用(yong)小角(jiao)鐵(tie)(tie)制作(zuo)， 吊(diao)點(dian)應在(zai)屋(wu)面板下均勻分布(施工(gong)前應對(dui)現場進行檢查，布點(dian)應避開(kai)(kai)頂(ding)面空調風筒及各(ge)種管道，若避不(bu)開(kai)(kai)時可采取角(jiao)鐵(tie)(tie)補充吊(diao)點(dian))，大面積(ji)或上(shang)人(ren)吊(diao)頂(ding)吊(diao)點(dian)間(jian)距為(wei)≤1000mm，一般吊(diao)頂(ding)的吊(diao)點(dian)間(jian)距為(wei)≤1200mm，用(yong)電錘在(zai)頂(ding)上(shang)打(da)孔，放置膨脹栓(shuan)擰緊(jin)固(gu)定于頂(ding)面上(shang)。

b.根據頂(ding)面水平線(xian)量出(chu)吊筋加(jia)工尺寸(cun)，若頂(ding)面平整(zheng)較差，吊桿(gan)長度不能統一時可(ke)拉通線(xian)，按實際尺寸(cun)逐—·找(zhao)出(chu)吊桿(gan)長度，吊桿(gan)可(ke)采取兩節搭接(jie)(jie)(焊(han)接(jie)(jie))方式，搭接(jie)(jie)長度大于吊桿(gan)直徑的8倍，將吊桿(gan)下端(duan)套扣(kou)(套絲時應加(jia)機油，以(yi)保證套扣(kou)質量)套絲長度不小(xiao)于50mm，然后將吊桿(gan)與角(jiao)鐵(tie)吊件焊(han)接(jie)(jie)，焊(han)接(jie)(jie)要(yao)精(jing)心(xin)操(cao)作，不得馬虎，焊(han)接(jie)(jie)部位應飽滿，確保足(zu)夠(gou)的強(qiang)度。

c.角(jiao)鐵吊(diao)件及(ji)吊(diao)桿加工完(wan)成后，按頂面水平線(xian)，付龍骨(gu)底面拉(la)通線(xian)，為(wei)吊(diao)桿安裝(zhuang)基準(zhun)線(xian)，進行吊(diao)桿安裝(zhuang)，吊(diao)桿間距(ju)(ju)應(ying)均勻(yun)，靠墻(qiang)邊吊(diao)桿距(ju)(ju)墻(qiang)不得大(da)于200mm，安裝(zhuang)后的(de)吊(diao)桿應(ying)垂直并在一(yi)條(tiao)線(xian)上，刷防(fang)銹漆兩遍(bian)，應(ying)按設計要求(qiu)調(diao)整起拱高度(起拱按短向跨度的(de)3-5/1000)。

d.吊(diao)桿(gan)距(ju)主龍骨端部(bu)距(ju)離不(bu)得(de)大于300mm，當大于300mm時應增(zeng)加吊(diao)桿(gan)。當吊(diao)桿(gan)與(yu)設備(bei)相(xiang)遇時，應調(diao)整并增(zeng)設吊(diao)桿(gan)，并不(bu)得(de)與(yu)設備(bei)共用吊(diao)桿(gan)。

步驟四：龍骨安裝：主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)應頂住墻(qiang)面(mian)，副龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)應緊(jin)貼墻(qiang)面(mian)。用(yong)(yong)(yong)吊(diao)件(jian)與(yu)(yu)主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)連接(jie)，同時擰緊(jin)吊(diao)件(jian)螺母，使(shi)主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)安(an)裝(zhuang)牢(lao)固(gu)，主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)連接(jie)件(jian)要錯(cuo)位(wei)安(an)裝(zhuang)以保證有足夠的(de)穩定(ding)(ding)(ding)性(xing)。大(da)(da)面(mian)積(ji)吊(diao)頂每隔12m在主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)上(shang)部焊接(jie)橫撐(cheng)大(da)(da)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)一道，以加強主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)側(ce)面(mian)穩定(ding)(ding)(ding)性(xing)及吊(diao)頂的(de)整體性(xing)。付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)安(an)裝(zhuang)用(yong)(yong)(yong)吊(diao)掛(件(jian))與(yu)(yu)主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)固(gu)定(ding)(ding)(ding)，吊(diao)掛必須用(yong)(yong)(yong)鉗子夾(jia)緊(jin)使(shi)付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)緊(jin)貼主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)，大(da)(da)面(mian)積(ji)或上(shang)人吊(diao)頂間(jian)(jian)距300mm，一般吊(diao)頂的(de)間(jian)(jian)距401mm(己考慮(lv)石膏板留3mm縫隙)，橫撐(cheng)付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)間(jian)(jian)距1500mm，用(yong)(yong)(yong)于(yu)(yu)石膏板中間(jian)(jian)及寬邊(1200mm)接(jie)頭處、平行于(yu)(yu)主(zhu)(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)用(yong)(yong)(yong)支托與(yu)(yu)付(fu)(fu)龍(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)(gu)(gu)連接(jie)固(gu)定(ding)(ding)(ding)。

步驟五：安裝石膏板：先(xian)檢查龍(long)骨(gu)安(an)(an)(an)裝(zhuang)(zhuang)是否(fou)平(ping)整，牢固(gu)(gu)，配件安(an)(an)(an)裝(zhuang)(zhuang)是否(fou)正確，然后(hou)才可進行(xing)石膏(gao)板(ban)安(an)(an)(an)裝(zhuang)(zhuang)，首先(xian)根(gen)據龍(long)骨(gu)間(jian)(jian)距在石膏(gao)板(ban)面上彈出(chu)龍(long)骨(gu)中心(xin)(xin)線，一般先(xian)從頂棚(peng)中心(xin)(xin)向周(zhou)(zhou)(zhou)圍鋪(pu)設，固(gu)(gu)定石膏(gao)板(ban)的高強(qiang)自攻絲(si)間(jian)(jian)距不大于150--170mm，由板(ban)中間(jian)(jian)向四(si)周(zhou)(zhou)(zhou)固(gu)(gu)定，強(qiang)攻絲(si)距板(ban)長邊(bian)10--15mm，短邊(bian)15--20mm，沉入板(ban)內1-2mm不得損壞紙面，應注意留3mm板(ban)縫(feng)(1200短邊(bian)留4--6mm縫(feng))，四(si)周(zhou)(zhou)(zhou)墻邊(bian)留10mm左(zuo)右縫(feng)隙以防(fang)伸縮(suo)變形，應錯位(錯開半板(ban))安(an)(an)(an)裝(zhuang)(zhuang)。

步驟六：按質量要求及檢查方法檢查：

a.輕鋼龍骨安裝位置正(zheng)確，牢固，無(wu)松動(dong)，吊桿(gan)做(zuo)防銹(xiu)處理。

b.石(shi)膏板應表面平整無污染，反銹，無脫層、翹曲、折裂等缺陷。
