1、工(gong)藝流程放(fang)線(xian)→固定吊桿→安裝配(pei)套龍骨→安裝鋁條板→清理

2、施工工藝

1）放線：放吊頂標高(gao)及龍骨(gu)位置(zhi)線(xian)(xian)(xian): 依據室內標高(gao)控制線(xian)(xian)(xian)（點），用(yong)尺或水(shui)準儀找出吊頂設計標高(gao)位置(zhi)，在四周墻上彈(dan)一道墨(mo)線(xian)(xian)(xian)，作為吊頂標高(gao)控制線(xian)(xian)(xian)。彈(dan)線(xian)(xian)(xian)應清晰，位置(zhi)應準確。再按吊頂排版圖，在樓板(ban)上彈(dan)出主(zhu)龍骨(gu)位置(zhi)線(xian)(xian)(xian)，最大(da)(da)間距(ju)應根據設計要求，不(bu)大(da)(da)于1200mm。然(ran)后在主(zhu)龍骨(gu)位置(zhi)線(xian)(xian)(xian)上用(yong)小“十”字(zi)線(xian)(xian)(xian)標出吊桿(gan)的固定位置(zhi)，一般吊桿(gan)間距(ju)為900-1200mm，距(ju)主(zhu)龍骨(gu)的端頭(tou)應不(bu)大(da)(da)于300mm，均勻布置(zhi)。若遇較(jiao)大(da)(da)設備(bei)或管道，吊桿(gan)間距(ju)大(da)(da)于1200mm時，宜采用(yong)型鋼扁擔來(lai)滿(man)足吊桿(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、風口及檢修口和其他設備，應設獨立吊(diao)桿(gan)(gan)安裝，不得固(gu)定在龍骨吊(diao)桿(gan)(gan)上。吊(diao)桿(gan)(gan)、角碼等金屬件和焊接處應做(zuo)防腐處理。

3）安裝主(zhu)龍(long)骨：主(zhu)龍(long)骨采用(yong)鍍鋅方管，與吊桿通過(guo)吊掛件連接。

4）安裝(zhuang)(zhuang)配(pei)(pei)套(tao)(tao)龍(long)(long)骨(gu)(gu)(gu)：配(pei)(pei)套(tao)(tao)龍(long)(long)骨(gu)(gu)(gu)安裝(zhuang)(zhuang)時(shi)采(cai)用螺絲與主龍(long)(long)骨(gu)(gu)(gu)固(gu)定(ding)連接。配(pei)(pei)套(tao)(tao)龍(long)(long)骨(gu)(gu)(gu)的間距(ju)一(yi)般(ban)為900-1200mm。配(pei)(pei)套(tao)(tao)龍(long)(long)骨(gu)(gu)(gu)端部(bu)懸(xuan)挑應(ying)(ying)不大于300mm，否則應(ying)(ying)增加吊桿。配(pei)(pei)套(tao)(tao)龍(long)(long)骨(gu)(gu)(gu)接長時(shi)，必須對(dui)接，不得有搭接，應(ying)(ying)采(cai)取專用連接件連接固(gu)定(ding)，每段(duan)配(pei)(pei)套(tao)(tao)龍(long)(long)骨(gu)(gu)(gu)的吊掛(gua)點(dian)不得少于2處(chu)，相(xiang)鄰(lin)兩根配(pei)(pei)套(tao)(tao)龍(long)(long)骨(gu)(gu)(gu)的接頭要相(xiang)互錯開，不得放在同一(yi)吊桿檔內。配(pei)(pei)套(tao)(tao)龍(long)(long)骨(gu)(gu)(gu)裝(zhuang)(zhuang)完后，應(ying)(ying)拉通線(xian)進行整體調平、調直(zhi)，并調好起拱(gong)度(du)，起拱(gong)高(gao)度(du)按(an)設計要求確定(ding)，一(yi)般(ban)為空間跨度(du)的3‰-5‰。

5）安(an)(an)裝鋁單(dan)板(ban)(ban)(ban)：安(an)(an)裝時，將鋁單(dan)板(ban)(ban)(ban)雙手托起，把鋁單(dan)板(ban)(ban)(ban)的兩邊(bian)的折邊(bian)同時卡入龍骨的卡槽內。施工時應(ying)從空間一端開始(shi)，按一個方(fang)向依(yi)次(ci)進行，拉通線(xian)進行調整，將板(ban)(ban)(ban)面(mian)調平(ping)(ping)，板(ban)(ban)(ban)邊(bian)與接縫調勻、調直，以(yi)確保(bao)板(ban)(ban)(ban)邊(bian)和接縫嚴密、順直，板(ban)(ban)(ban)面(mian)平(ping)(ping)整。

6）清(qing)理：在整(zheng)個施工(gong)過程(cheng)中(zhong)，應保(bao)護(hu)好金屬飾(shi)面板的保(bao)護(hu)膜(mo)。待交工(gong)前再撕(si)去保(bao)護(hu)膜(mo)，用專用清(qing)洗劑擦洗金屬飾(shi)面板表面，將(jiang)板面清(qing)理干凈。
