輕鋼龍(long)骨石膏板天花(hua)吊頂施工工藝(yi) 打(da)造時尚美觀天花(hua)

步驟一：清理現場：對施工現場墻、地面、灰塵、垃圾進(jin)行清理。

步驟二：彈線定位：根(gen)據設計及現場(chang)要求(qiu)、確(que)定50cm水平線(xian)，用尺量至(zhi)頂面設計標高(gao)線(xian)，在四周(zhou)墻面彈(dan)頂面水平線(xian)(水平線(xian)應以付龍(long)骨(gu)底面為準(zhun))，然后(hou)畫出(chu)龍(long)骨(gu)位置線(xian)和吊點(桿)布(bu)置線(xian)。

步驟三：安裝吊桿

a.角(jiao)(jiao)鐵(tie)(tie)(tie)吊件及吊筋加工(gong)：角(jiao)(jiao)鐵(tie)(tie)(tie)吊件采用L30*30角(jiao)(jiao)鐵(tie)(tie)(tie)加工(gong)，在(zai)(zai)角(jiao)(jiao)鐵(tie)(tie)(tie)面(mian)上(shang)(shang)劃出(chu)中(zhong)心(xin)線，對應打出(chu)一排 10或 8的孔、孔距(ju)45mm左右，再將角(jiao)(jiao)鐵(tie)(tie)(tie)分段切(qie)割下來。不上(shang)(shang)人吊件可(ke)(ke)用小角(jiao)(jiao)鐵(tie)(tie)(tie)制作， 吊點(dian)應在(zai)(zai)屋面(mian)板下均勻(yun)分布(施工(gong)前應對現場(chang)進行(xing)檢查，布點(dian)應避(bi)(bi)開(kai)(kai)頂面(mian)空(kong)調風筒及各(ge)種管道，若(ruo)避(bi)(bi)不開(kai)(kai)時可(ke)(ke)采取角(jiao)(jiao)鐵(tie)(tie)(tie)補充吊點(dian))，大面(mian)積(ji)或上(shang)(shang)人吊頂吊點(dian)間(jian)距(ju)為≤1000mm，一般(ban)吊頂的吊點(dian)間(jian)距(ju)為≤1200mm，用電錘在(zai)(zai)頂上(shang)(shang)打孔，放置膨脹栓(shuan)擰緊固定于頂面(mian)上(shang)(shang)。

b.根據頂面(mian)水平(ping)線量(liang)出吊(diao)筋加(jia)工尺(chi)寸，若頂面(mian)平(ping)整較差，吊(diao)桿長度(du)不能(neng)統一時可(ke)拉通(tong)線，按實際尺(chi)寸逐—·找出吊(diao)桿長度(du)，吊(diao)桿可(ke)采取兩節搭接(jie)(jie)(jie)(焊(han)接(jie)(jie)(jie))方式，搭接(jie)(jie)(jie)長度(du)大于吊(diao)桿直徑(jing)的8倍，將吊(diao)桿下端(duan)套扣(套絲(si)時應加(jia)機油，以保(bao)證套扣質量(liang))套絲(si)長度(du)不小于50mm，然后將吊(diao)桿與角(jiao)鐵吊(diao)件焊(han)接(jie)(jie)(jie)，焊(han)接(jie)(jie)(jie)要精(jing)心操作(zuo)，不得馬虎，焊(han)接(jie)(jie)(jie)部位應飽滿，確保(bao)足夠的強度(du)。

c.角鐵吊(diao)(diao)(diao)件(jian)及吊(diao)(diao)(diao)桿加工完成后(hou)，按頂面水平線(xian)，付龍(long)骨底面拉(la)通線(xian)，為吊(diao)(diao)(diao)桿安(an)裝基(ji)準(zhun)線(xian)，進行吊(diao)(diao)(diao)桿安(an)裝，吊(diao)(diao)(diao)桿間距應(ying)均勻，靠墻邊吊(diao)(diao)(diao)桿距墻不得大(da)于200mm，安(an)裝后(hou)的吊(diao)(diao)(diao)桿應(ying)垂直(zhi)并在(zai)一條(tiao)線(xian)上，刷防銹漆兩遍，應(ying)按設計要求調整(zheng)起拱高度(du)(起拱按短向跨度(du)的3-5/1000)。

d.吊(diao)(diao)桿(gan)(gan)距主龍骨(gu)端部(bu)距離不得大(da)于300mm，當大(da)于300mm時(shi)應增加吊(diao)(diao)桿(gan)(gan)。當吊(diao)(diao)桿(gan)(gan)與設備相(xiang)遇時(shi)，應調整并(bing)增設吊(diao)(diao)桿(gan)(gan)，并(bing)不得與設備共用吊(diao)(diao)桿(gan)(gan)。

步驟四：龍骨安裝：主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)應頂住墻面(mian)，副龍(long)(long)(long)骨(gu)(gu)應緊貼墻面(mian)。用(yong)吊(diao)(diao)件(jian)與主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)連接，同(tong)時擰緊吊(diao)(diao)件(jian)螺(luo)母，使主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)安裝(zhuang)牢固(gu)，主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)連接件(jian)要錯(cuo)位(wei)安裝(zhuang)以保(bao)證有(you)足(zu)夠的穩定(ding)性。大面(mian)積(ji)吊(diao)(diao)頂每隔12m在主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)上部焊接橫撐(cheng)大龍(long)(long)(long)骨(gu)(gu)一(yi)道，以加(jia)強主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)側面(mian)穩定(ding)性及吊(diao)(diao)頂的整體性。付(fu)龍(long)(long)(long)骨(gu)(gu)安裝(zhuang)用(yong)吊(diao)(diao)掛(件(jian))與主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)固(gu)定(ding)，吊(diao)(diao)掛必須用(yong)鉗子夾緊使付(fu)龍(long)(long)(long)骨(gu)(gu)緊貼主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)，大面(mian)積(ji)或上人吊(diao)(diao)頂間距(ju)300mm，一(yi)般吊(diao)(diao)頂的間距(ju)401mm(己考慮(lv)石膏(gao)板留(liu)3mm縫隙)，橫撐(cheng)付(fu)龍(long)(long)(long)骨(gu)(gu)間距(ju)1500mm，用(yong)于(yu)石膏(gao)板中間及寬邊(1200mm)接頭(tou)處、平行于(yu)主(zhu)(zhu)龍(long)(long)(long)骨(gu)(gu)用(yong)支托與付(fu)龍(long)(long)(long)骨(gu)(gu)連接固(gu)定(ding)。

步驟五：安裝石膏板：先檢查龍骨安(an)裝是否(fou)平整，牢固(gu)(gu)，配件(jian)安(an)裝是否(fou)正確(que)，然后才可進(jin)行石膏(gao)(gao)板(ban)(ban)安(an)裝，首先根據龍骨間距在石膏(gao)(gao)板(ban)(ban)面(mian)(mian)上彈出龍骨中心線，一般先從頂棚中心向周(zhou)圍鋪設，固(gu)(gu)定石膏(gao)(gao)板(ban)(ban)的(de)高強自攻絲間距不大于150--170mm，由(you)板(ban)(ban)中間向四周(zhou)固(gu)(gu)定，強攻絲距板(ban)(ban)長邊10--15mm，短邊15--20mm，沉入板(ban)(ban)內1-2mm不得(de)損壞(huai)紙面(mian)(mian)，應(ying)注(zhu)意留3mm板(ban)(ban)縫(1200短邊留4--6mm縫)，四周(zhou)墻邊留10mm左右縫隙以防(fang)伸縮變形(xing)，應(ying)錯位(錯開半板(ban)(ban))安(an)裝。

步驟六：按質量要求及檢查方法檢查：

a.輕鋼龍骨(gu)安裝位(wei)置正確，牢固，無(wu)松動(dong)，吊桿做防銹處(chu)理。

b.石(shi)膏板應表(biao)面平整無(wu)污染，反銹，無(wu)脫層、翹曲、折裂等缺陷。
