【外墻(qiang)鋁單板(ban)】外墻(qiang)鋁單板(ban)施工工藝 外墻(qiang)鋁單板(ban)施工流程(cheng)
1、工藝流程放線→固定吊(diao)桿→安裝配套龍骨→安裝鋁條板→清(qing)理
2、施工工藝
1)放線:放吊頂標(biao)高(gao)(gao)及龍(long)骨(gu)位(wei)置(zhi)線(xian)(xian): 依據室內標(biao)高(gao)(gao)控(kong)制線(xian)(xian)(點),用(yong)尺或水準儀找出吊(diao)(diao)頂設(she)(she)計標(biao)高(gao)(gao)位(wei)置(zhi),在(zai)四(si)周墻(qiang)上(shang)(shang)彈一(yi)道(dao)墨線(xian)(xian),作(zuo)為(wei)吊(diao)(diao)頂標(biao)高(gao)(gao)控(kong)制線(xian)(xian)。彈線(xian)(xian)應(ying)清晰,位(wei)置(zhi)應(ying)準確(que)。再按吊(diao)(diao)頂排版圖,在(zai)樓板上(shang)(shang)彈出主(zhu)龍(long)骨(gu)位(wei)置(zhi)線(xian)(xian),最(zui)大(da)間距(ju)應(ying)根據設(she)(she)計要求,不(bu)大(da)于1200mm。然后在(zai)主(zhu)龍(long)骨(gu)位(wei)置(zhi)線(xian)(xian)上(shang)(shang)用(yong)小“十”字線(xian)(xian)標(biao)出吊(diao)(diao)桿(gan)的固定位(wei)置(zhi),一(yi)般吊(diao)(diao)桿(gan)間距(ju)為(wei)900-1200mm,距(ju)主(zhu)龍(long)骨(gu)的端頭應(ying)不(bu)大(da)于300mm,均(jun)勻布置(zhi)。若(ruo)遇較大(da)設(she)(she)備(bei)或管道(dao),吊(diao)(diao)桿(gan)間距(ju)大(da)于1200mm時,宜采用(yong)型鋼扁擔來滿足吊(diao)(diao)桿(gan)間距(ju)。
2)固定吊桿:吊桿由角碼、鍍鋅角鋼及不小于8mm的通絲吊桿組成。吊桿與結構頂板通過膨脹螺栓連接。吊頂上的燈具、風(feng)口及檢修口和其他設(she)備,應設(she)獨立吊(diao)桿(gan)安裝(zhuang),不得固定(ding)在龍骨吊(diao)桿(gan)上。吊(diao)桿(gan)、角碼(ma)等金(jin)屬件(jian)和焊接處(chu)(chu)應做防腐處(chu)(chu)理。
3)安裝主龍骨:主龍骨采用鍍鋅方管,與吊桿(gan)通過吊掛件連接(jie)。
4)安裝配(pei)(pei)(pei)套(tao)(tao)龍(long)骨(gu)(gu):配(pei)(pei)(pei)套(tao)(tao)龍(long)骨(gu)(gu)安裝時采用螺(luo)絲與主龍(long)骨(gu)(gu)固(gu)定(ding)連(lian)接。配(pei)(pei)(pei)套(tao)(tao)龍(long)骨(gu)(gu)的間(jian)距(ju)一(yi)般為(wei)900-1200mm。配(pei)(pei)(pei)套(tao)(tao)龍(long)骨(gu)(gu)端部懸挑應不大于(yu)300mm,否則(ze)應增加吊桿。配(pei)(pei)(pei)套(tao)(tao)龍(long)骨(gu)(gu)接長時,必須對接,不得有搭(da)接,應采取(qu)專用連(lian)接件連(lian)接固(gu)定(ding),每段配(pei)(pei)(pei)套(tao)(tao)龍(long)骨(gu)(gu)的吊掛點不得少于(yu)2處,相(xiang)(xiang)鄰兩根配(pei)(pei)(pei)套(tao)(tao)龍(long)骨(gu)(gu)的接頭要相(xiang)(xiang)互錯開,不得放在同一(yi)吊桿檔內。配(pei)(pei)(pei)套(tao)(tao)龍(long)骨(gu)(gu)裝完后(hou),應拉通(tong)線(xian)進行整(zheng)體(ti)調平、調直,并(bing)調好起(qi)拱(gong)度,起(qi)拱(gong)高度按設計要求確定(ding),一(yi)般為(wei)空間(jian)跨度的3‰-5‰。
5)安裝(zhuang)鋁單板(ban)(ban)(ban):安裝(zhuang)時,將鋁單板(ban)(ban)(ban)雙手托起,把鋁單板(ban)(ban)(ban)的(de)兩邊(bian)的(de)折(zhe)邊(bian)同時卡入龍骨的(de)卡槽內(nei)。施工時應從空間一(yi)端開始,按一(yi)個方(fang)向依次進(jin)(jin)行,拉通線進(jin)(jin)行調整,將板(ban)(ban)(ban)面(mian)調平(ping),板(ban)(ban)(ban)邊(bian)與接縫(feng)調勻、調直,以確(que)保(bao)板(ban)(ban)(ban)邊(bian)和接縫(feng)嚴密、順(shun)直,板(ban)(ban)(ban)面(mian)平(ping)整。
6)清(qing)(qing)理(li):在(zai)整個施工過程中(zhong),應保護(hu)好金屬飾面板的保護(hu)膜。待交(jiao)工前(qian)再(zai)撕去保護(hu)膜,用專用清(qing)(qing)洗劑(ji)擦洗金屬飾面板表面,將板面清(qing)(qing)理(li)干凈。
