通風管道安裝程序：（1）風管組裝：當風管較短時，可一次在地面組裝而成，當風管較長時，可視安裝場地的情況，在地面分段組裝。推薦排煙管道組裝時應盡量調整風道的中心度和水平度，避免風管扭曲或上下起波，左右擺龍，每段風道不宜超過10m.組裝時，墊片應墊平，法蘭螺栓應均勻擰緊，螺母帽均朝向同一方向。（2）風管就位：風管就位前應檢查全部支架的水乎度和標高、檢查支架的牢固程度，風管就位可采用直接和吊具兩種方法。排煙管道廠家對風(feng)(feng)(feng)(feng)管(guan)斷面(mian)較(jiao)(jiao)小(xiao)，又(you)位置較(jiao)(jiao)低的可(ke)(ke)采(cai)用(yong)人工就(jiu)位方(fang)法，只(zhi)需搭設簡易腳(jiao)手(shou)架即(ji)可(ke)(ke)。當(dang)風(feng)(feng)(feng)(feng)管(guan)斷面(mian)較(jiao)(jiao)大且管(guan)段較(jiao)(jiao)長時，可(ke)(ke)采(cai)用(yong)滑輪(lun)、倒鏈、大繩(sheng)等方(fang)法吊(diao)裝。世紀星介紹為了便于風(feng)(feng)(feng)(feng)道就(jiu)位，一(yi)般多采(cai)用(yong)將風(feng)(feng)(feng)(feng)道吊(diao)在腳(jiao)手(shou)架上，然后再將其抬放在風(feng)(feng)(feng)(feng)道支架上的方(fang)法。腳(jiao)手(shou)架應(ying)沿(yan)其風(feng)(feng)(feng)(feng)道長度(du)(du)方(fang)向搭設，高度(du)(du)和位置應(ying)適合施(shi)工操作，吊(diao)裝順序應(ying)先干管(guan)后支、立管(guan)，吊(diao)起時，吊(diao)點應(ying)牢(lao)固(gu)，兩吊(diao)點應(ying)均勻受力。垂直風(feng)(feng)(feng)(feng)管(guan)可(ke)(ke)采(cai)用(yong)人工和大繩(sheng)輔(fu)助就(jiu)位。調(diao)整(zheng)風(feng)(feng)(feng)(feng)管(guan)保證垂直度(du)(du)要(yao)求(qiu)。（3）風(feng)(feng)(feng)(feng)道調(diao)直：就(jiu)位在支架上的風(feng)(feng)(feng)(feng)道，應(ying)撥正(zheng)位置，調(diao)整(zheng)風(feng)(feng)(feng)(feng)道橫平豎直，然后再按圖集要(yao)求(qiu)固(gu)定。
