After finishing above work, we can install some outfittings in subsection item, general situation:aircondition duct, stainless duct galvanized duct, duct support, the other ventilation outfitting before vertical loading the block of hull and joining of fabricated section. 各分段通風(fēng)管安裝應(yīng)根據(jù)相應(yīng)分段風(fēng)管安裝圖，風(fēng)管（支架）加工零件圖和材料清單來組織安裝，檢查風(fēng)管等附件標高是否與圖紙相符，甲板艙壁上開孔是否符合要求。 Installing duct in every block should be reference for duct installation drawing, support manufacturing drawing, part list. Check the quality of duct。 insure hole on the hull correctly 風(fēng)管支架定位 → 風(fēng)管定位（通風(fēng)附件） → 風(fēng)管連接密封 Place support→install duct(outfitting) →connect duct ●風(fēng)管支架安裝是風(fēng)管安裝的第一道工序。支架形式應(yīng)根據(jù)風(fēng)管截面大小及分段具體情況選擇，但必須符合設(shè)計圖紙或國家標準。風(fēng)管支架無特殊要求時，應(yīng)符合以下要求： Installing support is the first step of duct installation. According to area of duct or site situation and GB, to choose which type of the duct. If no special reqirements of duct, we must obey these rules: 水平安裝的矩行風(fēng)管長邊小于 400mm，其支架間距不超過 3m，大于或等于 400mm，其支架間距不超過 2m。 If longer side＜ 400mm(horizontal installation), the distance of support＜ 3 m。 If longer side＞ 400mm(horizontal installation), the distance of support＜ 2 m。 垂直安裝的風(fēng)管支架間距為 3m，并在每根立管上設(shè)置不少于兩個固定件。 If the distance of support ＞ 3m(vertical installation), each duct should have more than two support. 風(fēng)管支架定位應(yīng)根據(jù)風(fēng)管安裝標高來定，對于矩形風(fēng)管，它有風(fēng)管上標高和下標高兩種標高；圓形風(fēng)管是以風(fēng)管中心作為標高尺寸。 The position of duct supporter shall be positioned according to installation elevation, refer to the rectangle air duct which has upper elevation and low elevation of air duct, the center of circle air duct can as the elevation. 風(fēng)管支架吊桿通常焊接在橫梁或扶強材上，如焊接在甲板上時應(yīng) 加復(fù)板。 Supports are usually welded on beam or construction but if welded on deck, plus pound plate. ……千錘百煉，軍工品質(zhì) —— 永昇中央空調(diào)…… PAGE 17 船用空調(diào)通風(fēng)系統(tǒng)安裝施工工藝規(guī)范 注意： 30000 噸多用途船的吊架要求帶復(fù)板并熱鍍鋅處理 Note: The hanger for 30,000T multipurpose vessel shall be provided with pound plate and shall be hot galvanized. ●風(fēng)管安裝： Connect installation 施工現(xiàn)場具備安裝條件時，應(yīng)將預(yù)制加工好的風(fēng)管和附件按照安裝圖順序和不同系統(tǒng)運至現(xiàn)場，風(fēng)管和附件應(yīng)按照系統(tǒng)圖順序編號，并按編號順序進行安裝。 風(fēng)管連接 Connect duct 風(fēng)管安裝應(yīng)按照安裝圖要求進行，風(fēng)管安裝都在分段內(nèi)安裝，風(fēng)管之間和風(fēng)管與附件之間連接大多采用法蘭連接，連接的法蘭與法蘭之間應(yīng)墊上一層阻燃橡膠墊兩圈直徑5mm 密封橡膠繩；也有用套管連接和對接焊連接形式，如下圖。另外在分段與分段之間設(shè)有合攏管，合攏管應(yīng)在分段合攏后才可安裝連接。 Duct should be installed according to installation drawing, mostly the duct install in block, connect by flange, the 5mm rubber rope between each duct。 or thimble joint and welding joint.
