一、工藝流程

　　a)吊頂保溫安裝工藝：排版--龍骨安裝--保溫板就位固(gu)定--調整--細部處理。

　　b)排版(ban)：根椐施工圖紙(zhi)及實際結構(gou)確定(ding)吊頂板排版(ban)。

　　c)龍(long)骨安裝：采(cai)用￠12鍍(du)(du)鋅(xin)吊(diao)桿作(zuo)為吊(diao)筋，40*80*2mm鍍(du)(du)鋅(xin)方(fang)(fang)管作(zuo)為主(zhu)龍(long)骨，間(jian)距(ju)(ju)1.8m(根據實際檁條預留孔調(diao)整)，40*60*1.5mm鍍(du)(du)鋅(xin)方(fang)(fang)管作(zuo)為次龍(long)骨，間(jian)距(ju)(ju)1.78m~3.5m(參照檁條間(jian)距(ju)(ju))，龍(long)骨連接(jie)(jie)處焊接(jie)(jie)。

　　d)保(bao)溫板(ban)(ban)(ban)就位(wei)固(gu)定(ding)：將保(bao)溫板(ban)(ban)(ban)提(ti)升至(zhi)安(an)裝高度，將保(bao)溫板(ban)(ban)(ban)就位(wei)找(zhao)正找(zhao)平(ping)后(hou)采用自攻釘將板(ban)(ban)(ban)固(gu)定(ding)于龍骨上。然后(hou)安(an)裝下一張(zhang)頂板(ban)(ban)(ban)，用緊線(xian)器打緊兩張(zhang)板(ban)(ban)(ban)，確(que)保(bao)板(ban)(ban)(ban)與板(ban)(ban)(ban)之(zhi)間結合(he)緊密，依次安(an)裝，直至(zhi)頂板(ban)(ban)(ban)安(an)裝完畢，并進行相關洞口的(de)開口。

　　e)調(diao)整：板安裝完(wan)畢后，進行調(diao)平。

　　f)細部(bu)處理：頂(ding)庫板(ban)(ban)全部(bu)安裝(zhuang)完(wan)成后，對板(ban)(ban)板(ban)(ban)接(jie)縫(feng)(feng)(feng)要進(jin)行(xing)(xing)打膠處理，其他預(yu)留(liu)縫(feng)(feng)(feng)隙采(cai)用(yong)(yong)聚氨酯發泡進(jin)行(xing)(xing)填滿，吊頂(ding)下(xia)部(bu)邊縫(feng)(feng)(feng)采(cai)用(yong)(yong)圓弧鋁進(jin)行(xing)(xing)收(shou)邊，中(zhong)縫(feng)(feng)(feng)采(cai)用(yong)(yong)平(ping)板(ban)(ban)鋁合金進(jin)行(xing)(xing)收(shou)邊。上部(bu)縫(feng)(feng)(feng)隙不進(jin)行(xing)(xing)收(shou)邊處理，處理完(wan)畢后再進(jin)行(xing)(xing)整體清潔。

　　二、連接(jie)點處理考慮到(dao)使用(yong)過程(cheng)中可能出現的正負風壓(ya)問題，我方采(cai)用(yong)以下方式進行解決:

　　a)在主龍(long)骨吊桿上(shang)加裝剛(gang)(gang)性(xing)(xing)支(zhi)撐(cheng)，以屋(wu)面檁(lin)(lin)條為(wei)參照，每隔一道(dao)(dao)(dao)屋(wu)面檁(lin)(lin)條在相應的主龍(long)骨吊桿上(shang)加裝剛(gang)(gang)性(xing)(xing)支(zhi)撐(cheng)，共十道(dao)(dao)(dao)，其中靠兩邊(bian)四道(dao)(dao)(dao)為(wei)剛(gang)(gang)性(xing)(xing)套管(guan)(3.2*2.5套管(guan))，剛(gang)(gang)性(xing)(xing)支(zhi)撐(cheng)間距為(wei)3.6m，考慮到鋼管(guan)長細比限制，中間六(liu)道(dao)(dao)(dao)采用(yong)方管(guan)現場制作(zuo)，每個剛(gang)(gang)性(xing)(xing)支(zhi)采用(yong)兩道(dao)(dao)(dao)40*60*1.5mm鍍鋅方管(guan)連(lian)接(jie)并與上(shang)部屋(wu)面檁(lin)(lin)條用(yong)自攻(gong)絲連(lian)接(jie)，剛(gang)(gang)性(xing)(xing)支(zhi)撐(cheng)間距為(wei)3.6m。

　　b)周圈(quan)龍骨(gu)與墻(qiang)體之間采(cai)取半剛性支撐，采(cai)用(yong)50mm款(50)角鐵件一(yi)端與墻(qiang)體固定(ding)，一(yi)端截面上開孔(孔尺寸為12mm*36mm)并與周圈(quan)龍骨(gu)連接，之間預留20~30mm縫隙作為活動(dong)量。
