輕(qing)鋼龍骨石膏板(ban)天花吊(diao)頂施工工藝 打造時(shi)尚美觀天花

步驟一：清理現場：對施工現(xian)場(chang)墻、地面、灰塵、垃(la)圾(ji)進行清理。

步驟二：彈線定位：根(gen)據設(she)計及現場要求(qiu)、確定50cm水平(ping)線，用尺量至頂(ding)面(mian)(mian)設(she)計標高線，在四周(zhou)墻面(mian)(mian)彈頂(ding)面(mian)(mian)水平(ping)線(水平(ping)線應(ying)以付龍(long)骨底面(mian)(mian)為準)，然后畫(hua)出龍(long)骨位置線和吊點(桿)布置線。

步驟三：安裝吊桿

a.角(jiao)(jiao)(jiao)鐵(tie)吊(diao)件及(ji)吊(diao)筋加工(gong)：角(jiao)(jiao)(jiao)鐵(tie)吊(diao)件采用L30*30角(jiao)(jiao)(jiao)鐵(tie)加工(gong)，在角(jiao)(jiao)(jiao)鐵(tie)面(mian)(mian)上劃(hua)出(chu)中心線，對應打出(chu)一排 10或(huo) 8的(de)孔(kong)、孔(kong)距45mm左右，再將角(jiao)(jiao)(jiao)鐵(tie)分段切割下來。不上人(ren)吊(diao)件可用小角(jiao)(jiao)(jiao)鐵(tie)制作， 吊(diao)點(dian)(dian)應在屋面(mian)(mian)板(ban)下均勻分布(bu)(施工(gong)前應對現場進(jin)行檢查，布(bu)點(dian)(dian)應避開(kai)頂(ding)面(mian)(mian)空調風筒及(ji)各種管(guan)道(dao)，若避不開(kai)時可采取(qu)角(jiao)(jiao)(jiao)鐵(tie)補(bu)充(chong)吊(diao)點(dian)(dian))，大面(mian)(mian)積或(huo)上人(ren)吊(diao)頂(ding)吊(diao)點(dian)(dian)間距為(wei)≤1000mm，一般吊(diao)頂(ding)的(de)吊(diao)點(dian)(dian)間距為(wei)≤1200mm，用電錘在頂(ding)上打孔(kong)，放置膨脹栓擰緊固定于(yu)頂(ding)面(mian)(mian)上。

b.根據(ju)頂面水平線(xian)量(liang)出(chu)吊(diao)筋加工尺(chi)(chi)寸，若(ruo)頂面平整較差，吊(diao)桿(gan)(gan)長(chang)度(du)(du)不能統(tong)一時可拉通線(xian)，按實際尺(chi)(chi)寸逐—·找出(chu)吊(diao)桿(gan)(gan)長(chang)度(du)(du)，吊(diao)桿(gan)(gan)可采取兩節搭接(jie)(jie)(焊接(jie)(jie))方式，搭接(jie)(jie)長(chang)度(du)(du)大于(yu)吊(diao)桿(gan)(gan)直徑的8倍，將吊(diao)桿(gan)(gan)下端套(tao)扣(kou)(套(tao)絲時應(ying)加機(ji)油，以保證套(tao)扣(kou)質量(liang))套(tao)絲長(chang)度(du)(du)不小于(yu)50mm，然后(hou)將吊(diao)桿(gan)(gan)與角鐵吊(diao)件焊接(jie)(jie)，焊接(jie)(jie)要(yao)精心(xin)操作(zuo)，不得(de)馬虎，焊接(jie)(jie)部(bu)位應(ying)飽滿，確(que)保足(zu)夠的強度(du)(du)。

c.角(jiao)鐵(tie)吊(diao)(diao)件及吊(diao)(diao)桿(gan)(gan)(gan)加(jia)工完成后，按(an)頂面(mian)水平線，付龍骨底面(mian)拉通線，為吊(diao)(diao)桿(gan)(gan)(gan)安裝基準線，進行吊(diao)(diao)桿(gan)(gan)(gan)安裝，吊(diao)(diao)桿(gan)(gan)(gan)間距(ju)應(ying)均勻(yun)，靠墻(qiang)邊(bian)吊(diao)(diao)桿(gan)(gan)(gan)距(ju)墻(qiang)不得大(da)于(yu)200mm，安裝后的吊(diao)(diao)桿(gan)(gan)(gan)應(ying)垂直并(bing)在一條(tiao)線上，刷防銹漆兩遍，應(ying)按(an)設計要求調整(zheng)起(qi)拱高度(du)(起(qi)拱按(an)短向跨度(du)的3-5/1000)。

d.吊桿距(ju)主(zhu)龍骨端部距(ju)離(li)不得(de)大(da)(da)于(yu)300mm，當大(da)(da)于(yu)300mm時應(ying)增(zeng)(zeng)加(jia)吊桿。當吊桿與設(she)備(bei)相(xiang)遇時，應(ying)調整并(bing)增(zeng)(zeng)設(she)吊桿，并(bing)不得(de)與設(she)備(bei)共用吊桿。

步驟四：龍骨安裝：主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)應(ying)頂(ding)(ding)住墻面(mian)(mian)，副龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)應(ying)緊(jin)貼墻面(mian)(mian)。用(yong)(yong)吊(diao)件與(yu)(yu)主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)連(lian)(lian)接(jie)(jie)，同時(shi)擰緊(jin)吊(diao)件螺母，使(shi)主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)安(an)裝牢(lao)固，主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)連(lian)(lian)接(jie)(jie)件要錯位安(an)裝以保證有足夠的(de)穩定(ding)(ding)性。大面(mian)(mian)積吊(diao)頂(ding)(ding)每隔12m在主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)上部焊接(jie)(jie)橫(heng)撐大龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)一道，以加強主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)側面(mian)(mian)穩定(ding)(ding)性及(ji)吊(diao)頂(ding)(ding)的(de)整體性。付(fu)(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)安(an)裝用(yong)(yong)吊(diao)掛(件)與(yu)(yu)主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)固定(ding)(ding)，吊(diao)掛必須用(yong)(yong)鉗子夾緊(jin)使(shi)付(fu)(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)緊(jin)貼主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)，大面(mian)(mian)積或上人(ren)吊(diao)頂(ding)(ding)間距300mm，一般吊(diao)頂(ding)(ding)的(de)間距401mm(己考(kao)慮石(shi)膏板(ban)(ban)留3mm縫隙)，橫(heng)撐付(fu)(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)間距1500mm，用(yong)(yong)于石(shi)膏板(ban)(ban)中間及(ji)寬邊(1200mm)接(jie)(jie)頭處、平行(xing)于主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)用(yong)(yong)支托與(yu)(yu)付(fu)(fu)龍(long)(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)連(lian)(lian)接(jie)(jie)固定(ding)(ding)。

步驟五：安裝石膏板：先(xian)檢(jian)查龍(long)骨(gu)安(an)裝(zhuang)是(shi)否平整，牢固，配(pei)件安(an)裝(zhuang)是(shi)否正確，然后才可(ke)進行石膏板(ban)安(an)裝(zhuang)，首先(xian)根據(ju)龍(long)骨(gu)間距在石膏板(ban)面(mian)上彈出龍(long)骨(gu)中(zhong)心(xin)線，一(yi)般先(xian)從頂棚中(zhong)心(xin)向周(zhou)圍鋪設，固定石膏板(ban)的高(gao)強(qiang)自攻(gong)絲間距不大于150--170mm，由板(ban)中(zhong)間向四(si)周(zhou)固定，強(qiang)攻(gong)絲距板(ban)長(chang)邊(bian)10--15mm，短邊(bian)15--20mm，沉入板(ban)內1-2mm不得損壞紙面(mian)，應注意(yi)留(liu)3mm板(ban)縫(1200短邊(bian)留(liu)4--6mm縫)，四(si)周(zhou)墻邊(bian)留(liu)10mm左右(you)縫隙以防(fang)伸縮變(bian)形，應錯(cuo)位(wei)(錯(cuo)開(kai)半板(ban))安(an)裝(zhuang)。

步驟六：按質量要求及檢查方法檢查：

a.輕鋼龍(long)骨(gu)安(an)裝位(wei)置正確，牢固，無松動，吊(diao)桿做防銹處理。

b.石膏(gao)板應(ying)表面平(ping)整無污染，反銹，無脫層(ceng)、翹曲、折裂等(deng)缺陷。
