步驟一:清理現場:對施工現場(chang)墻、地面、灰(hui)塵、垃(la)圾進(jin)行清理。
步驟二:彈線定位:根據設(she)計(ji)及現場要求、確定50cm水平(ping)線(xian)(xian)(xian),用尺(chi)量至頂面(mian)設(she)計(ji)標高線(xian)(xian)(xian),在四周墻面(mian)彈(dan)頂面(mian)水平(ping)線(xian)(xian)(xian)(水平(ping)線(xian)(xian)(xian)應以付龍骨(gu)底面(mian)為準),然后畫出(chu)龍骨(gu)位置(zhi)(zhi)線(xian)(xian)(xian)和(he)吊(diao)點(桿(gan))布置(zhi)(zhi)線(xian)(xian)(xian)。
步驟三:安裝吊桿
a.角鐵吊(diao)(diao)(diao)件(jian)及吊(diao)(diao)(diao)筋加工(gong)(gong):角鐵吊(diao)(diao)(diao)件(jian)采(cai)用L30*30角鐵加工(gong)(gong),在角鐵面上劃出(chu)中心線(xian),對應打(da)出(chu)一(yi)排 10或(huo) 8的孔(kong)、孔(kong)距45mm左右,再將角鐵分(fen)段切割下來。不上人(ren)吊(diao)(diao)(diao)件(jian)可(ke)用小角鐵制作(zuo), 吊(diao)(diao)(diao)點(dian)應在屋面板下均勻(yun)分(fen)布(施工(gong)(gong)前(qian)應對現(xian)場進行檢查,布點(dian)應避(bi)開頂面空調風筒(tong)及各種管(guan)道,若避(bi)不開時(shi)可(ke)采(cai)取(qu)角鐵補充(chong)吊(diao)(diao)(diao)點(dian)),大(da)面積或(huo)上人(ren)吊(diao)(diao)(diao)頂吊(diao)(diao)(diao)點(dian)間距為≤1000mm,一(yi)般吊(diao)(diao)(diao)頂的吊(diao)(diao)(diao)點(dian)間距為≤1200mm,用電錘在頂上打(da)孔(kong),放置膨脹栓擰(ning)緊固定于頂面上。
b.根據頂面水平線量出(chu)吊(diao)(diao)筋加(jia)工尺寸,若頂面平整較差,吊(diao)(diao)桿(gan)(gan)長(chang)度不能(neng)統(tong)一時可拉通線,按實際尺寸逐—·找出(chu)吊(diao)(diao)桿(gan)(gan)長(chang)度,吊(diao)(diao)桿(gan)(gan)可采取兩(liang)節(jie)搭(da)(da)接(jie)(焊(han)接(jie))方式,搭(da)(da)接(jie)長(chang)度大于吊(diao)(diao)桿(gan)(gan)直徑的8倍(bei),將(jiang)(jiang)吊(diao)(diao)桿(gan)(gan)下端套(tao)(tao)扣(kou)(套(tao)(tao)絲時應加(jia)機油,以保(bao)證套(tao)(tao)扣(kou)質量)套(tao)(tao)絲長(chang)度不小于50mm,然后將(jiang)(jiang)吊(diao)(diao)桿(gan)(gan)與角鐵吊(diao)(diao)件焊(han)接(jie),焊(han)接(jie)要(yao)精心操作,不得(de)馬虎,焊(han)接(jie)部位應飽滿,確(que)保(bao)足夠(gou)的強(qiang)度。
c.角鐵吊(diao)件及吊(diao)桿(gan)(gan)(gan)加工完成后,按頂面(mian)(mian)水平線(xian),付龍骨底面(mian)(mian)拉通線(xian),為吊(diao)桿(gan)(gan)(gan)安裝(zhuang)基準(zhun)線(xian),進行(xing)吊(diao)桿(gan)(gan)(gan)安裝(zhuang),吊(diao)桿(gan)(gan)(gan)間距(ju)應均勻,靠墻(qiang)邊吊(diao)桿(gan)(gan)(gan)距(ju)墻(qiang)不得(de)大于(yu)200mm,安裝(zhuang)后的吊(diao)桿(gan)(gan)(gan)應垂直并在一(yi)條線(xian)上,刷防銹漆(qi)兩(liang)遍(bian),應按設(she)計要求調(diao)整(zheng)起拱高度(起拱按短向(xiang)跨(kua)度的3-5/1000)。
d.吊(diao)(diao)(diao)桿距主龍骨(gu)端部距離不得大(da)于300mm,當(dang)大(da)于300mm時(shi)應增加吊(diao)(diao)(diao)桿。當(dang)吊(diao)(diao)(diao)桿與設備相遇時(shi),應調整(zheng)并(bing)增設吊(diao)(diao)(diao)桿,并(bing)不得與設備共用吊(diao)(diao)(diao)桿。
步驟四:龍骨安裝:主(zhu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)應(ying)(ying)頂(ding)住墻面,副龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)應(ying)(ying)緊(jin)貼(tie)墻面。用(yong)(yong)(yong)吊(diao)(diao)件與(yu)主(zhu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)連(lian)接(jie),同時(shi)擰緊(jin)吊(diao)(diao)件螺母,使主(zhu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)安裝(zhuang)牢固(gu),主(zhu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)連(lian)接(jie)件要錯位安裝(zhuang)以保證有足夠的穩定性。大面積吊(diao)(diao)頂(ding)每隔12m在主(zhu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)上部焊接(jie)橫撐大龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)一道,以加強(qiang)主(zhu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)側面穩定性及吊(diao)(diao)頂(ding)的整體(ti)性。付(fu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)安裝(zhuang)用(yong)(yong)(yong)吊(diao)(diao)掛(件)與(yu)主(zhu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)固(gu)定,吊(diao)(diao)掛必須用(yong)(yong)(yong)鉗子夾緊(jin)使付(fu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)緊(jin)貼(tie)主(zhu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu),大面積或上人吊(diao)(diao)頂(ding)間距(ju)300mm,一般吊(diao)(diao)頂(ding)的間距(ju)401mm(己考慮石膏板留3mm縫隙),橫撐付(fu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)間距(ju)1500mm,用(yong)(yong)(yong)于石膏板中間及寬邊(bian)(1200mm)接(jie)頭處、平行于主(zhu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)用(yong)(yong)(yong)支托與(yu)付(fu)龍(long)(long)(long)(long)骨(gu)(gu)(gu)(gu)(gu)連(lian)接(jie)固(gu)定。
步驟五:安裝石膏板:先(xian)檢查龍(long)(long)骨安裝(zhuang)是否(fou)平(ping)整,牢固,配件安裝(zhuang)是否(fou)正確,然后才可進行石(shi)膏(gao)板(ban)(ban)安裝(zhuang),首先(xian)根據(ju)龍(long)(long)骨間距在石(shi)膏(gao)板(ban)(ban)面上(shang)彈出龍(long)(long)骨中心線,一(yi)般先(xian)從頂棚(peng)中心向周圍鋪設(she),固定(ding)石(shi)膏(gao)板(ban)(ban)的(de)高強自攻(gong)絲間距不大于(yu)150--170mm,由板(ban)(ban)中間向四周固定(ding),強攻(gong)絲距板(ban)(ban)長邊10--15mm,短邊15--20mm,沉入板(ban)(ban)內1-2mm不得損壞紙面,應注意留3mm板(ban)(ban)縫(1200短邊留4--6mm縫),四周墻(qiang)邊留10mm左(zuo)右縫隙(xi)以防伸縮變形,應錯位(wei)(錯開半板(ban)(ban))安裝(zhuang)。
步驟六:按質量要求及檢查方法檢查:
a.輕鋼龍骨安裝(zhuang)位置(zhi)正確,牢固(gu),無松動,吊桿做防銹處理。
