(1)彈線定位

根據設計圖紙，結合具體情況，將龍骨及(ji)(ji)吊(diao)點位(wei)(wei)置(zhi)彈到樓板底面上。如(ru)果吊(diao)頂(ding)設計要求具(ju)有(you)一定(ding)造型或圖案，應(ying)先彈出吊(diao)頂(ding)對稱軸線，龍骨(gu)及(ji)(ji)吊(diao)點位(wei)(wei)置(zhi)應(ying)對稱布(bu)置(zhi)。龍骨(gu)和吊(diao)桿(gan)的間(jian)距、主(zhu)龍骨(gu)的間(jian)距是影(ying)響吊(diao)頂(ding)高度(du)的重(zhong)要因素。不(bu)同的龍骨(gu)斷面及(ji)(ji)吊(diao)點間(jian)距，都有(you)可能影(ying)響主(zhu)龍骨(gu)之(zhi)間(jian)的距離。各(ge)種吊(diao)頂(ding)、龍骨(gu)間(jian)距和吊(diao)桿(gan)間(jian)距一般都控(kong)制在(zai)1.0一1.2m以內。彈線應(ying)清晰，位(wei)(wei)置(zhi)準(zhun)確(que)。鋁(lv)合金(jin)板吊(diao)頂(ding)，如(ru)果是將板條卡在(zai)龍骨(gu)之(zhi)上，龍骨(gu)應(ying)與板成垂直;如(ru)用螺釘固定(ding)，則要視板條的形狀，以及(ji)(ji)設計上的要求而具(ju)體掌握。

(2)確定吊頂標高

將(jiang)設計標高(gao)線彈(dan)到四周(zhou)墻面(mian)或(huo)柱面(mian)上;如果吊頂有不(bu)同標高(gao)，那么應(ying)將(jiang)變截面(mian)的(de)(de)(de)位置彈(dan)到樓板(ban)上。然后(hou)將(jiang)角(jiao)(jiao)(jiao)鋁(lv)或(huo)其他(ta)封(feng)(feng)口材(cai)料固定(ding)在墻面(mian)或(huo)柱面(mian)，封(feng)(feng)口材(cai)料的(de)(de)(de)底面(mian)與標高(gao)線重合，角(jiao)(jiao)(jiao)鋁(lv)常用(yong)的(de)(de)(de)規格為25mm x25mm，鋁(lv)合金板(ban)吊頂的(de)(de)(de)角(jiao)(jiao)(jiao)鋁(lv)應(ying)同板(ban)的(de)(de)(de)色彩一致。角(jiao)(jiao)(jiao)鋁(lv)多(duo)用(yong)高(gao)強(qiang)水泥(ni)釘(ding)固定(ding)，亦可用(yong)射釘(ding)固定(ding)。

(3)吊桿或鍍鋅鐵絲的固定

與結(jie)構(gou)一端的固定(ding)(ding)，常用(yong)(yong)(yong)的辦法是用(yong)(yong)(yong)射釘槍(qiang)(亦稱石屎槍(qiang))將(jiang)吊(diao)桿(gan)或(huo)(huo)鍍鋅(xin)鐵絲(si)固定(ding)(ding)。可以選用(yong)(yong)(yong)尾部(bu)帶孔或(huo)(huo)不(bu)帶孔的兩種(zhong)射釘規格。如果用(yong)(yong)(yong)角鋼一類材料做吊(diao)桿(gan)，則龍骨也大部(bu)分(fen)采用(yong)(yong)(yong)普(pu)通型鋼，應用(yong)(yong)(yong)沖(chong)擊鉆(zhan)(zhan)固定(ding)(ding)脹管螺栓，然后將(jiang)吊(diao)桿(gan)焊在螺栓上。吊(diao)桿(gan)與龍骨的固定(ding)(ding).可以采用(yong)(yong)(yong)焊接或(huo)(huo)鉆(zhan)(zhan)孔用(yong)(yong)(yong)螺栓固定(ding)(ding)。

(4)龍骨安裝與調平

安(an)裝(zhuang)時，根據(ju)已確(que)定(ding)的(de)(de)主(zhu)(zhu)(zhu)龍(long)骨(gu)(gu)(gu)(gu)(gu)(大(da)龍(long)骨(gu)(gu)(gu)(gu)(gu))位(wei)置及(ji)確(que)定(ding)的(de)(de)標(biao)高(gao)(gao)線(xian)，先大(da)致(zhi)將(jiang)其基(ji)本就(jiu)位(wei)。次龍(long)骨(gu)(gu)(gu)(gu)(gu)(中、小龍(long)骨(gu)(gu)(gu)(gu)(gu))應緊(jin)(jin)貼主(zhu)(zhu)(zhu)龍(long)骨(gu)(gu)(gu)(gu)(gu)安(an)裝(zhuang)就(jiu)位(wei)。龍(long)骨(gu)(gu)(gu)(gu)(gu)就(jiu)位(wei)后，然后再滿(man)拉縱橫控制標(biao)高(gao)(gao)線(xian)(十字中心線(xian))，從(cong)一(yi)(yi)端(duan)開始，一(yi)(yi)邊(bian)安(an)裝(zhuang)，一(yi)(yi)邊(bian)調整，最后再精調一(yi)(yi)遍(bian)，直(zhi)到(dao)龍(long)骨(gu)(gu)(gu)(gu)(gu)調平(ping)和調直(zhi)為止。如果(guo)面(mian)(mian)積(ji)較(jiao)大(da)，在中間(jian)還應考慮水平(ping)線(xian)適當起(qi)拱。調平(ping)時應注意一(yi)(yi)定(ding)要從(cong)一(yi)(yi)端(duan)調向另一(yi)(yi)端(duan)，要做(zuo)到(dao)縱橫平(ping)直(zhi)。，特(te)別(bie)對(dui)于鋁(lv)(lv)合(he)金吊(diao)頂(ding)，龍(long)骨(gu)(gu)(gu)(gu)(gu)的(de)(de)調平(ping)調直(zhi)是施工工序比(bi)較(jiao)麻煩的(de)(de)一(yi)(yi)道.龍(long)骨(gu)(gu)(gu)(gu)(gu)是否調平(ping)，也是板條(tiao)(tiao)吊(diao)頂(ding)質量(liang)控制的(de)(de)關鍵。因為只有龍(long)骨(gu)(gu)(gu)(gu)(gu)調平(ping)，才能使板條(tiao)(tiao)飾面(mian)(mian)達到(dao)理想的(de)(de)裝(zhuang)飾效(xiao)果(guo)，否則，波浪(lang)式的(de)(de)吊(diao)頂(ding)表面(mian)(mian)，整體看上去(qu)很不(bu)順眼。邊(bian)龍(long)骨(gu)(gu)(gu)(gu)(gu)宜(yi)沿(yan)墻面(mian)(mian)或(huo)柱(zhu)面(mian)(mian)標(biao)高(gao)(gao)線(xian)釘牢。固(gu)定(ding)時一(yi)(yi)般(ban)常(chang)用高(gao)(gao)強水泥釘，釘的(de)(de)間(jian)距不(bu)宜(yi)大(da)于50cm。如果(guo)基(ji)層材料(liao)強度(du)(du)(du)較(jiao)低，緊(jin)(jin)固(gu)力不(bu)好，應采取相(xiang)應的(de)(de)措施，改用脹管螺栓或(huo)加大(da)釘的(de)(de)長(chang)(chang)度(du)(du)(du)等(deng)辦法。邊(bian)龍(long)骨(gu)(gu)(gu)(gu)(gu)一(yi)(yi)般(ban)不(bu)承重，只起(qi)封口作(zuo)用。一(yi)(yi)般(ban)選用連(lian)接件(jian)接長(chang)(chang)。連(lian)接件(jian)可用鋁(lv)(lv)合(he)金，亦可用鍍鋅鋼板，在其表面(mian)(mian)沖成倒刺，與(yu)主(zhu)(zhu)(zhu)龍(long)骨(gu)(gu)(gu)(gu)(gu)方孔相(xiang)連(lian)。全面(mian)(mian)校(xiao)正主(zhu)(zhu)(zhu)、次龍(long)骨(gu)(gu)(gu)(gu)(gu)的(de)(de)位(wei)置及(ji)水平(ping)度(du)(du)(du)，連(lian)接件(jian)應錯位(wei)安(an)裝(zhuang)。

(5)頂棚板安裝

頂棚板(ban)安(an)裝(zhuang)(zhuang)時，要使板(ban)材的幾(ji)何尺(chi)寸能(neng)適應(ying)鋁合(he)金(jin)龍骨吊頂所承受的荷載能(neng)力。如格構尺(chi)寸為600mm x 900mm,600mm x1200mm時.就不能(neng)安(an)裝(zhuang)(zhuang)石膏板(ban)，而只能(neng)安(an)裝(zhuang)(zhuang)礦棉(mian)板(ban)。
