1、工(gong)藝流程放線→固定(ding)吊(diao)桿→安裝配套龍骨(gu)→安裝鋁條板→清(qing)理

2、施工工藝

1）放線：放吊頂標高及龍(long)骨(gu)位(wei)置(zhi)線(xian)(xian): 依(yi)據室(shi)內(nei)標高控制線(xian)(xian)（點(dian)），用(yong)尺(chi)或(huo)水準儀找出(chu)(chu)吊(diao)頂(ding)設計(ji)標高位(wei)置(zhi)，在四周(zhou)墻上(shang)彈(dan)(dan)一(yi)道墨線(xian)(xian)，作為吊(diao)頂(ding)標高控制線(xian)(xian)。彈(dan)(dan)線(xian)(xian)應(ying)(ying)清晰，位(wei)置(zhi)應(ying)(ying)準確。再(zai)按(an)吊(diao)頂(ding)排版圖，在樓板上(shang)彈(dan)(dan)出(chu)(chu)主龍(long)骨(gu)位(wei)置(zhi)線(xian)(xian)，最大間距應(ying)(ying)根(gen)據設計(ji)要求，不大于(yu)1200mm。然后在主龍(long)骨(gu)位(wei)置(zhi)線(xian)(xian)上(shang)用(yong)小“十(shi)”字(zi)線(xian)(xian)標出(chu)(chu)吊(diao)桿(gan)(gan)的固定位(wei)置(zhi)，一(yi)般吊(diao)桿(gan)(gan)間距為900-1200mm，距主龍(long)骨(gu)的端頭(tou)應(ying)(ying)不大于(yu)300mm，均勻布置(zhi)。若遇較大設備或(huo)管(guan)道，吊(diao)桿(gan)(gan)間距大于(yu)1200mm時，宜采用(yong)型(xing)鋼扁擔來(lai)滿足吊(diao)桿(gan)(gan)間距。

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(xiu)口和(he)其(qi)他設(she)備，應(ying)設(she)獨立(li)吊桿安(an)裝(zhuang)，不得(de)固定在龍骨(gu)吊桿上。吊桿、角(jiao)碼(ma)等金屬件和(he)焊接處應(ying)做防腐處理(li)。

3）安(an)裝(zhuang)主(zhu)(zhu)龍骨：主(zhu)(zhu)龍骨采用鍍鋅(xin)方管，與吊(diao)(diao)桿通過吊(diao)(diao)掛件連接。

4）安裝配套(tao)(tao)(tao)(tao)龍骨(gu)(gu)(gu)(gu)：配套(tao)(tao)(tao)(tao)龍骨(gu)(gu)(gu)(gu)安裝時采用螺(luo)絲(si)與主龍骨(gu)(gu)(gu)(gu)固定連(lian)接(jie)(jie)。配套(tao)(tao)(tao)(tao)龍骨(gu)(gu)(gu)(gu)的(de)間(jian)距一般為900-1200mm。配套(tao)(tao)(tao)(tao)龍骨(gu)(gu)(gu)(gu)端部懸挑應不(bu)大(da)于(yu)300mm，否則應增加吊桿。配套(tao)(tao)(tao)(tao)龍骨(gu)(gu)(gu)(gu)接(jie)(jie)長時，必須(xu)對(dui)接(jie)(jie)，不(bu)得(de)(de)(de)有搭接(jie)(jie)，應采取專用連(lian)接(jie)(jie)件連(lian)接(jie)(jie)固定，每段配套(tao)(tao)(tao)(tao)龍骨(gu)(gu)(gu)(gu)的(de)吊掛點不(bu)得(de)(de)(de)少于(yu)2處，相鄰(lin)兩根配套(tao)(tao)(tao)(tao)龍骨(gu)(gu)(gu)(gu)的(de)接(jie)(jie)頭要相互錯開，不(bu)得(de)(de)(de)放在同一吊桿檔內。配套(tao)(tao)(tao)(tao)龍骨(gu)(gu)(gu)(gu)裝完后，應拉(la)通(tong)線進(jin)行整體調(diao)平、調(diao)直(zhi)，并調(diao)好起拱度，起拱高度按(an)設計要求確定，一般為空間(jian)跨度的(de)3‰-5‰。

5）安裝鋁單(dan)板(ban)(ban)(ban)：安裝時(shi)，將鋁單(dan)板(ban)(ban)(ban)雙手托起，把(ba)鋁單(dan)板(ban)(ban)(ban)的(de)兩(liang)邊(bian)(bian)的(de)折(zhe)邊(bian)(bian)同時(shi)卡(ka)入龍骨的(de)卡(ka)槽內。施工(gong)時(shi)應從空間(jian)一(yi)端(duan)開始，按一(yi)個方向依(yi)次進行，拉(la)通線進行調整，將板(ban)(ban)(ban)面調平(ping)，板(ban)(ban)(ban)邊(bian)(bian)與接(jie)縫調勻、調直(zhi)，以確保板(ban)(ban)(ban)邊(bian)(bian)和接(jie)縫嚴密、順直(zhi)，板(ban)(ban)(ban)面平(ping)整。

6）清理(li)：在整個施工過程(cheng)中，應(ying)保(bao)護好金屬(shu)飾面(mian)板的保(bao)護膜。待交工前再撕去保(bao)護膜，用專用清洗(xi)劑(ji)擦洗(xi)金屬(shu)飾面(mian)板表面(mian)，將(jiang)板面(mian)清理(li)干凈。
