輕鋼龍骨石膏板(ban)天(tian)花(hua)吊(diao)頂施工(gong)工(gong)藝 打造時尚美觀天(tian)花(hua)

步驟一：清理現場：對(dui)施工現場墻、地(di)面、灰塵、垃(la)圾進行清理。

步驟二：彈線定位：根據設計(ji)及現場要求、確定50cm水(shui)平(ping)線，用尺量至頂面設計(ji)標高線，在四(si)周(zhou)墻(qiang)面彈頂面水(shui)平(ping)線(水(shui)平(ping)線應以付龍(long)骨底面為準)，然后畫出龍(long)骨位置線和吊點(桿)布置線。

步驟三：安裝吊桿

a.角(jiao)鐵(tie)(tie)(tie)吊件及(ji)吊筋加工(gong)：角(jiao)鐵(tie)(tie)(tie)吊件采用(yong)(yong)L30*30角(jiao)鐵(tie)(tie)(tie)加工(gong)，在(zai)角(jiao)鐵(tie)(tie)(tie)面(mian)上(shang)劃出中(zhong)心線(xian)，對應(ying)打出一排 10或(huo) 8的(de)孔(kong)、孔(kong)距45mm左(zuo)右，再(zai)將角(jiao)鐵(tie)(tie)(tie)分段切割(ge)下(xia)來(lai)。不上(shang)人吊件可用(yong)(yong)小角(jiao)鐵(tie)(tie)(tie)制作， 吊點應(ying)在(zai)屋(wu)面(mian)板下(xia)均勻分布(bu)(施工(gong)前應(ying)對現場進行檢查，布(bu)點應(ying)避開頂(ding)(ding)(ding)面(mian)空調(diao)風筒(tong)及(ji)各(ge)種管道，若(ruo)避不開時(shi)可采取角(jiao)鐵(tie)(tie)(tie)補充吊點)，大(da)面(mian)積(ji)或(huo)上(shang)人吊頂(ding)(ding)(ding)吊點間距為≤1000mm，一般吊頂(ding)(ding)(ding)的(de)吊點間距為≤1200mm，用(yong)(yong)電錘在(zai)頂(ding)(ding)(ding)上(shang)打孔(kong)，放置膨脹栓(shuan)擰緊固定于頂(ding)(ding)(ding)面(mian)上(shang)。

b.根據頂面水平(ping)線量(liang)(liang)出吊(diao)(diao)筋加(jia)工尺(chi)寸，若頂面平(ping)整較(jiao)差，吊(diao)(diao)桿(gan)長(chang)度不能統一時可(ke)拉通線，按實際尺(chi)寸逐—·找出吊(diao)(diao)桿(gan)長(chang)度，吊(diao)(diao)桿(gan)可(ke)采取(qu)兩節搭接(焊(han)(han)接)方(fang)式，搭接長(chang)度大于(yu)吊(diao)(diao)桿(gan)直(zhi)徑的(de)(de)8倍，將吊(diao)(diao)桿(gan)下端套(tao)扣(套(tao)絲時應(ying)加(jia)機油(you)，以(yi)保證套(tao)扣質(zhi)量(liang)(liang))套(tao)絲長(chang)度不小于(yu)50mm，然后將吊(diao)(diao)桿(gan)與角鐵吊(diao)(diao)件焊(han)(han)接，焊(han)(han)接要精心操作，不得馬(ma)虎，焊(han)(han)接部位應(ying)飽(bao)滿(man)，確保足(zu)夠的(de)(de)強度。

c.角(jiao)鐵吊(diao)(diao)(diao)(diao)件及吊(diao)(diao)(diao)(diao)桿(gan)加工完成(cheng)后(hou)，按頂(ding)面(mian)水(shui)平(ping)線(xian)(xian)，付龍骨底面(mian)拉通線(xian)(xian)，為吊(diao)(diao)(diao)(diao)桿(gan)安(an)裝(zhuang)(zhuang)(zhuang)基準(zhun)線(xian)(xian)，進(jin)行吊(diao)(diao)(diao)(diao)桿(gan)安(an)裝(zhuang)(zhuang)(zhuang)，吊(diao)(diao)(diao)(diao)桿(gan)間距應均勻，靠(kao)墻邊吊(diao)(diao)(diao)(diao)桿(gan)距墻不(bu)得大于200mm，安(an)裝(zhuang)(zhuang)(zhuang)后(hou)的吊(diao)(diao)(diao)(diao)桿(gan)應垂直并在(zai)一條線(xian)(xian)上，刷防銹漆兩遍，應按設計要求調整起拱高度(du)(起拱按短(duan)向跨度(du)的3-5/1000)。

d.吊(diao)桿距主龍骨端部(bu)距離(li)不(bu)得大于300mm，當(dang)(dang)大于300mm時應增加(jia)吊(diao)桿。當(dang)(dang)吊(diao)桿與設(she)備相遇時，應調整并(bing)增設(she)吊(diao)桿，并(bing)不(bu)得與設(she)備共用(yong)吊(diao)桿。

步驟四：龍骨安裝：主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)應頂(ding)住(zhu)墻面(mian)，副龍(long)(long)(long)(long)(long)骨(gu)應緊(jin)貼(tie)墻面(mian)。用(yong)吊件與(yu)主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)連接(jie)，同時(shi)擰緊(jin)吊件螺(luo)母，使(shi)主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)安裝(zhuang)牢固，主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)連接(jie)件要錯位安裝(zhuang)以保證有(you)足(zu)夠的(de)穩(wen)定(ding)性。大(da)面(mian)積吊頂(ding)每(mei)隔(ge)12m在主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)上(shang)部焊接(jie)橫撐(cheng)大(da)龍(long)(long)(long)(long)(long)骨(gu)一道，以加強主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)側面(mian)穩(wen)定(ding)性及吊頂(ding)的(de)整(zheng)體性。付(fu)龍(long)(long)(long)(long)(long)骨(gu)安裝(zhuang)用(yong)吊掛(gua)(件)與(yu)主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)固定(ding)，吊掛(gua)必須用(yong)鉗子夾(jia)緊(jin)使(shi)付(fu)龍(long)(long)(long)(long)(long)骨(gu)緊(jin)貼(tie)主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)，大(da)面(mian)積或上(shang)人(ren)吊頂(ding)間(jian)(jian)距300mm，一般吊頂(ding)的(de)間(jian)(jian)距401mm(己考慮石膏板留3mm縫隙)，橫撐(cheng)付(fu)龍(long)(long)(long)(long)(long)骨(gu)間(jian)(jian)距1500mm，用(yong)于(yu)石膏板中(zhong)間(jian)(jian)及寬邊(1200mm)接(jie)頭處、平行(xing)于(yu)主(zhu)(zhu)龍(long)(long)(long)(long)(long)骨(gu)用(yong)支(zhi)托與(yu)付(fu)龍(long)(long)(long)(long)(long)骨(gu)連接(jie)固定(ding)。
