【外墻(qiang)(qiang)(qiang)鋁(lv)單(dan)板(ban)】外墻(qiang)(qiang)(qiang)鋁(lv)單(dan)板(ban)施工(gong)(gong)工(gong)(gong)藝 外墻(qiang)(qiang)(qiang)鋁(lv)單(dan)板(ban)施工(gong)(gong)流(liu)程

1、工藝流程(cheng)放線(xian)→固定吊桿(gan)→安裝配套龍骨(gu)→安裝鋁條板(ban)→清理

2、施工工藝

1）放線：放吊頂標(biao)高(gao)(gao)及龍(long)(long)骨位置線(xian)(xian): 依據(ju)室內(nei)標(biao)高(gao)(gao)控(kong)(kong)制線(xian)(xian)（點），用尺或水準儀找出(chu)吊(diao)(diao)頂(ding)設計標(biao)高(gao)(gao)位置，在(zai)四(si)周(zhou)墻上彈一(yi)道墨線(xian)(xian)，作為吊(diao)(diao)頂(ding)標(biao)高(gao)(gao)控(kong)(kong)制線(xian)(xian)。彈線(xian)(xian)應清晰，位置應準確。再按吊(diao)(diao)頂(ding)排(pai)版圖，在(zai)樓板(ban)上彈出(chu)主龍(long)(long)骨位置線(xian)(xian)，最大(da)(da)(da)(da)間距(ju)(ju)應根據(ju)設計要(yao)求(qiu)，不大(da)(da)(da)(da)于1200mm。然后在(zai)主龍(long)(long)骨位置線(xian)(xian)上用小“十(shi)”字線(xian)(xian)標(biao)出(chu)吊(diao)(diao)桿(gan)的(de)固定(ding)位置，一(yi)般吊(diao)(diao)桿(gan)間距(ju)(ju)為900-1200mm，距(ju)(ju)主龍(long)(long)骨的(de)端頭應不大(da)(da)(da)(da)于300mm，均勻布置。若遇較大(da)(da)(da)(da)設備或管(guan)道，吊(diao)(diao)桿(gan)間距(ju)(ju)大(da)(da)(da)(da)于1200mm時，宜(yi)采用型鋼(gang)扁擔來滿足吊(diao)(diao)桿(gan)間距(ju)(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、風口(kou)及(ji)檢修(xiu)口(kou)和其他設備，應設獨立吊桿安裝，不得固定在龍骨吊桿上(shang)。吊桿、角碼等金屬件和焊接(jie)處應做防(fang)腐處理(li)。

3）安裝主(zhu)龍(long)骨：主(zhu)龍(long)骨采用鍍鋅(xin)方管，與吊桿通過吊掛(gua)件連接(jie)。

4）安(an)裝配(pei)套(tao)(tao)龍(long)骨(gu)：配(pei)套(tao)(tao)龍(long)骨(gu)安(an)裝時(shi)采用螺絲與主(zhu)龍(long)骨(gu)固定(ding)(ding)連接(jie)。配(pei)套(tao)(tao)龍(long)骨(gu)的間(jian)距一(yi)般為900-1200mm。配(pei)套(tao)(tao)龍(long)骨(gu)端部(bu)懸挑應(ying)(ying)不(bu)大于(yu)300mm，否則應(ying)(ying)增加吊(diao)桿(gan)。配(pei)套(tao)(tao)龍(long)骨(gu)接(jie)長時(shi)，必須對接(jie)，不(bu)得(de)有(you)搭(da)接(jie)，應(ying)(ying)采取專用連接(jie)件連接(jie)固定(ding)(ding)，每段配(pei)套(tao)(tao)龍(long)骨(gu)的吊(diao)掛(gua)點(dian)不(bu)得(de)少(shao)于(yu)2處，相(xiang)鄰(lin)兩根配(pei)套(tao)(tao)龍(long)骨(gu)的接(jie)頭(tou)要(yao)相(xiang)互錯開(kai)，不(bu)得(de)放在同一(yi)吊(diao)桿(gan)檔內。配(pei)套(tao)(tao)龍(long)骨(gu)裝完(wan)后，應(ying)(ying)拉通線進行整體(ti)調平、調直，并調好起拱(gong)度，起拱(gong)高度按設計要(yao)求(qiu)確定(ding)(ding)，一(yi)般為空(kong)間(jian)跨度的3‰-5‰。

5）安裝(zhuang)鋁(lv)單板(ban)(ban)(ban)：安裝(zhuang)時，將(jiang)鋁(lv)單板(ban)(ban)(ban)雙手托(tuo)起，把鋁(lv)單板(ban)(ban)(ban)的兩邊(bian)的折邊(bian)同時卡入龍骨的卡槽內(nei)。施工(gong)時應從(cong)空間一(yi)端開始，按一(yi)個(ge)方向依(yi)次進(jin)行，拉通(tong)線(xian)進(jin)行調(diao)整(zheng)，將(jiang)板(ban)(ban)(ban)面調(diao)平，板(ban)(ban)(ban)邊(bian)與接(jie)(jie)縫調(diao)勻、調(diao)直(zhi)，以確保板(ban)(ban)(ban)邊(bian)和接(jie)(jie)縫嚴(yan)密、順直(zhi)，板(ban)(ban)(ban)面平整(zheng)。

6）清(qing)理(li)：在整個施工過(guo)程中，應(ying)保(bao)護(hu)好(hao)金屬(shu)飾(shi)面(mian)板的保(bao)護(hu)膜。待交工前再撕去保(bao)護(hu)膜，用(yong)專用(yong)清(qing)洗劑擦洗金屬(shu)飾(shi)面(mian)板表面(mian)，將板面(mian)清(qing)理(li)干凈。
