【外墻(qiang)鋁單(dan)板】外墻(qiang)鋁單(dan)板施(shi)工(gong)工(gong)藝 外墻(qiang)鋁單(dan)板施(shi)工(gong)流程

1、工藝(yi)流程放線→固(gu)定吊桿→安裝配套龍(long)骨→安裝鋁條板→清理

2、施工工藝

1）放線：放吊頂標高(gao)(gao)及(ji)龍(long)骨(gu)位(wei)(wei)置(zhi)線(xian)(xian): 依據室(shi)內標高(gao)(gao)控制線(xian)(xian)（點），用尺或(huo)水準儀找出吊(diao)頂(ding)(ding)設計(ji)標高(gao)(gao)位(wei)(wei)置(zhi)，在四周墻上(shang)彈一道(dao)墨(mo)線(xian)(xian)，作為吊(diao)頂(ding)(ding)標高(gao)(gao)控制線(xian)(xian)。彈線(xian)(xian)應清晰，位(wei)(wei)置(zhi)應準確。再按吊(diao)頂(ding)(ding)排版圖(tu)，在樓板上(shang)彈出主(zhu)(zhu)龍(long)骨(gu)位(wei)(wei)置(zhi)線(xian)(xian)，最大間距(ju)應根據設計(ji)要求(qiu)，不(bu)大于(yu)(yu)1200mm。然后在主(zhu)(zhu)龍(long)骨(gu)位(wei)(wei)置(zhi)線(xian)(xian)上(shang)用小“十”字(zi)線(xian)(xian)標出吊(diao)桿(gan)的固定位(wei)(wei)置(zhi)，一般吊(diao)桿(gan)間距(ju)為900-1200mm，距(ju)主(zhu)(zhu)龍(long)骨(gu)的端頭應不(bu)大于(yu)(yu)300mm，均勻布置(zhi)。若(ruo)遇較(jiao)大設備或(huo)管(guan)道(dao)，吊(diao)桿(gan)間距(ju)大于(yu)(yu)1200mm時(shi)，宜采用型鋼(gang)扁擔來滿足吊(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、風口(kou)(kou)及檢(jian)修口(kou)(kou)和其他設(she)備(bei)，應(ying)設(she)獨(du)立吊桿(gan)安裝，不得固定在(zai)龍骨吊桿(gan)上。吊桿(gan)、角碼等金(jin)屬件和焊接(jie)處應(ying)做防腐(fu)處理(li)。

3）安裝主龍(long)(long)骨：主龍(long)(long)骨采用鍍鋅方管，與(yu)吊桿通過吊掛(gua)件連接(jie)。

4）安裝配(pei)套(tao)龍骨(gu)：配(pei)套(tao)龍骨(gu)安裝時(shi)采用螺絲與主龍骨(gu)固(gu)定(ding)連接(jie)。配(pei)套(tao)龍骨(gu)的間距一(yi)般(ban)(ban)為900-1200mm。配(pei)套(tao)龍骨(gu)端部懸挑應不(bu)大于300mm，否則應增(zeng)加吊桿(gan)。配(pei)套(tao)龍骨(gu)接(jie)長時(shi)，必須對接(jie)，不(bu)得(de)有搭接(jie)，應采取專(zhuan)用連接(jie)件連接(jie)固(gu)定(ding)，每段(duan)配(pei)套(tao)龍骨(gu)的吊掛點不(bu)得(de)少于2處(chu)，相鄰兩根配(pei)套(tao)龍骨(gu)的接(jie)頭要相互(hu)錯開(kai)，不(bu)得(de)放在同一(yi)吊桿(gan)檔內。配(pei)套(tao)龍骨(gu)裝完后，應拉通(tong)線進(jin)行整(zheng)體調平、調直，并調好起拱度，起拱高度按設計要求確(que)定(ding)，一(yi)般(ban)(ban)為空(kong)間跨度的3‰-5‰。

5）安裝鋁單(dan)(dan)板(ban)(ban)(ban)：安裝時，將鋁單(dan)(dan)板(ban)(ban)(ban)雙(shuang)手托起(qi)，把鋁單(dan)(dan)板(ban)(ban)(ban)的兩(liang)邊的折(zhe)邊同(tong)時卡(ka)入龍(long)骨的卡(ka)槽內。施工(gong)時應(ying)從空間一端開始，按一個方向依次進行，拉通(tong)線進行調(diao)整，將板(ban)(ban)(ban)面調(diao)平，板(ban)(ban)(ban)邊與(yu)接縫(feng)調(diao)勻、調(diao)直(zhi)，以(yi)確(que)保板(ban)(ban)(ban)邊和接縫(feng)嚴(yan)密、順直(zhi)，板(ban)(ban)(ban)面平整。

6）清(qing)(qing)理：在整(zheng)個施(shi)工(gong)過程中(zhong)，應保護(hu)(hu)好金屬飾面板(ban)(ban)的(de)保護(hu)(hu)膜。待交工(gong)前(qian)再撕去保護(hu)(hu)膜，用(yong)專用(yong)清(qing)(qing)洗劑擦洗金屬飾面板(ban)(ban)表面，將板(ban)(ban)面清(qing)(qing)理干凈。
