輕(qing)鋼龍骨石膏板天(tian)花(hua)吊頂(ding)施工工藝 打(da)造時尚美(mei)觀天(tian)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)計及現場要求、確定50cm水(shui)平線(xian)，用尺量至(zhi)頂面(mian)設(she)計標高(gao)線(xian)，在四(si)周墻面(mian)彈頂面(mian)水(shui)平線(xian)(水(shui)平線(xian)應以付龍骨底面(mian)為準(zhun))，然后(hou)畫出龍骨位(wei)置線(xian)和吊點(桿(gan))布置線(xian)。

步驟三：安裝吊桿

a.角(jiao)(jiao)鐵(tie)吊(diao)(diao)(diao)件(jian)及(ji)(ji)吊(diao)(diao)(diao)筋加(jia)工(gong)：角(jiao)(jiao)鐵(tie)吊(diao)(diao)(diao)件(jian)采用(yong)L30*30角(jiao)(jiao)鐵(tie)加(jia)工(gong)，在角(jiao)(jiao)鐵(tie)面(mian)上劃出(chu)中(zhong)心線，對應打(da)出(chu)一(yi)排 10或(huo) 8的孔(kong)(kong)、孔(kong)(kong)距45mm左右，再將角(jiao)(jiao)鐵(tie)分段切(qie)割下來(lai)。不(bu)上人(ren)吊(diao)(diao)(diao)件(jian)可用(yong)小角(jiao)(jiao)鐵(tie)制作， 吊(diao)(diao)(diao)點(dian)應在屋面(mian)板下均(jun)勻分布(施工(gong)前應對現場進行檢查，布點(dian)應避開頂(ding)(ding)面(mian)空調(diao)風筒及(ji)(ji)各種管道，若避不(bu)開時可采取角(jiao)(jiao)鐵(tie)補充吊(diao)(diao)(diao)點(dian))，大面(mian)積(ji)或(huo)上人(ren)吊(diao)(diao)(diao)頂(ding)(ding)吊(diao)(diao)(diao)點(dian)間距為≤1000mm，一(yi)般吊(diao)(diao)(diao)頂(ding)(ding)的吊(diao)(diao)(diao)點(dian)間距為≤1200mm，用(yong)電(dian)錘在頂(ding)(ding)上打(da)孔(kong)(kong)，放置膨脹栓擰(ning)緊固定于頂(ding)(ding)面(mian)上。

b.根據頂面(mian)(mian)水(shui)平線量出吊(diao)(diao)筋加工尺寸(cun)，若頂面(mian)(mian)平整較差，吊(diao)(diao)桿長度不能(neng)統(tong)一時(shi)可拉通線，按實際尺寸(cun)逐—·找出吊(diao)(diao)桿長度，吊(diao)(diao)桿可采取兩(liang)節(jie)搭接(焊接)方式，搭接長度大于吊(diao)(diao)桿直(zhi)徑(jing)的8倍，將(jiang)吊(diao)(diao)桿下端(duan)套(tao)(tao)(tao)扣(kou)(套(tao)(tao)(tao)絲時(shi)應加機油，以保證套(tao)(tao)(tao)扣(kou)質量)套(tao)(tao)(tao)絲長度不小于50mm，然后將(jiang)吊(diao)(diao)桿與角(jiao)鐵(tie)吊(diao)(diao)件焊接，焊接要(yao)精心操作，不得馬虎，焊接部(bu)位應飽滿，確保足夠的強(qiang)度。

c.角鐵吊(diao)(diao)(diao)件及吊(diao)(diao)(diao)桿加(jia)工(gong)完成后(hou)，按頂面水平線，付龍骨底面拉通線，為吊(diao)(diao)(diao)桿安(an)裝(zhuang)基準線，進行吊(diao)(diao)(diao)桿安(an)裝(zhuang)，吊(diao)(diao)(diao)桿間距應均勻(yun)，靠墻邊(bian)吊(diao)(diao)(diao)桿距墻不得大(da)于200mm，安(an)裝(zhuang)后(hou)的(de)(de)吊(diao)(diao)(diao)桿應垂(chui)直(zhi)并在(zai)一(yi)條線上，刷防銹漆兩遍，應按設計要(yao)求調(diao)整起拱高度(du)(起拱按短向(xiang)跨度(du)的(de)(de)3-5/1000)。

d.吊(diao)桿(gan)距主龍(long)骨端(duan)部距離不得大于300mm，當大于300mm時(shi)應增(zeng)加吊(diao)桿(gan)。當吊(diao)桿(gan)與設(she)備(bei)相遇時(shi)，應調整(zheng)并增(zeng)設(she)吊(diao)桿(gan)，并不得與設(she)備(bei)共用(yong)吊(diao)桿(gan)。

步驟四：龍骨安裝：主(zhu)龍(long)(long)(long)骨(gu)(gu)應頂(ding)住墻(qiang)面(mian)，副龍(long)(long)(long)骨(gu)(gu)應緊(jin)貼(tie)墻(qiang)面(mian)。用(yong)吊(diao)(diao)(diao)件(jian)與(yu)主(zhu)龍(long)(long)(long)骨(gu)(gu)連(lian)(lian)接(jie)，同時擰(ning)緊(jin)吊(diao)(diao)(diao)件(jian)螺母，使主(zhu)龍(long)(long)(long)骨(gu)(gu)安裝(zhuang)(zhuang)牢(lao)固(gu)，主(zhu)龍(long)(long)(long)骨(gu)(gu)連(lian)(lian)接(jie)件(jian)要錯位安裝(zhuang)(zhuang)以保證(zheng)有足夠的穩定(ding)性(xing)(xing)(xing)。大面(mian)積(ji)吊(diao)(diao)(diao)頂(ding)每隔(ge)12m在主(zhu)龍(long)(long)(long)骨(gu)(gu)上部(bu)焊接(jie)橫(heng)撐(cheng)大龍(long)(long)(long)骨(gu)(gu)一道，以加強主(zhu)龍(long)(long)(long)骨(gu)(gu)側面(mian)穩定(ding)性(xing)(xing)(xing)及吊(diao)(diao)(diao)頂(ding)的整(zheng)體性(xing)(xing)(xing)。付龍(long)(long)(long)骨(gu)(gu)安裝(zhuang)(zhuang)用(yong)吊(diao)(diao)(diao)掛(gua)(件(jian))與(yu)主(zhu)龍(long)(long)(long)骨(gu)(gu)固(gu)定(ding)，吊(diao)(diao)(diao)掛(gua)必須(xu)用(yong)鉗子夾緊(jin)使付龍(long)(long)(long)骨(gu)(gu)緊(jin)貼(tie)主(zhu)龍(long)(long)(long)骨(gu)(gu)，大面(mian)積(ji)或上人吊(diao)(diao)(diao)頂(ding)間(jian)(jian)距300mm，一般吊(diao)(diao)(diao)頂(ding)的間(jian)(jian)距401mm(己考慮(lv)石膏板留(liu)3mm縫隙)，橫(heng)撐(cheng)付龍(long)(long)(long)骨(gu)(gu)間(jian)(jian)距1500mm，用(yong)于石膏板中間(jian)(jian)及寬邊(1200mm)接(jie)頭處、平行于主(zhu)龍(long)(long)(long)骨(gu)(gu)用(yong)支托與(yu)付龍(long)(long)(long)骨(gu)(gu)連(lian)(lian)接(jie)固(gu)定(ding)。

步驟五：安裝石膏板：先檢查龍(long)(long)骨安(an)裝是(shi)否平(ping)整，牢(lao)固(gu)，配(pei)件安(an)裝是(shi)否正確，然后才可進行(xing)石(shi)膏(gao)板(ban)安(an)裝，首先根(gen)據龍(long)(long)骨間距(ju)在石(shi)膏(gao)板(ban)面(mian)上彈出龍(long)(long)骨中(zhong)心線，一(yi)般先從頂棚中(zhong)心向周(zhou)圍(wei)鋪設(she)，固(gu)定(ding)石(shi)膏(gao)板(ban)的高強自攻絲(si)(si)間距(ju)不大于150--170mm，由板(ban)中(zhong)間向四(si)周(zhou)固(gu)定(ding)，強攻絲(si)(si)距(ju)板(ban)長邊10--15mm，短(duan)(duan)邊15--20mm，沉入板(ban)內(nei)1-2mm不得損壞(huai)紙面(mian)，應(ying)注(zhu)意(yi)留(liu)3mm板(ban)縫(feng)(1200短(duan)(duan)邊留(liu)4--6mm縫(feng))，四(si)周(zhou)墻邊留(liu)10mm左右縫(feng)隙以防伸縮變形，應(ying)錯(cuo)位(wei)(錯(cuo)開半(ban)板(ban))安(an)裝。

步驟六：按質量要求及檢查方法檢查：

a.輕鋼(gang)龍骨安裝位置(zhi)正(zheng)確(que)，牢固(gu)，無(wu)松動，吊桿(gan)做(zuo)防銹處理。

b.石膏板(ban)應(ying)表面平整無污染，反銹，無脫層、翹曲、折裂等缺陷(xian)。
