濟南通風(fēng)管道是用于空氣輸送和分布的管道系統(tǒng)。凈化通風(fēng)管道是工業(yè)與民用建筑的通風(fēng)與空調(diào)工程用金屬或非金屬管道，是為了使空氣流通，降低有害氣體濃度的一種基礎(chǔ)設(shè)施。你知道風(fēng)管的安裝及中間檢驗怎么做嗎？下面

Jinan ventilation pipeline is a pipeline system used for air transmission and distribution. Purified ventilation duct is a metal or non-metallic duct for ventilation and air conditioning engineering of industrial and civil buildings. It is an infrastructure to make air circulate and reduce the concentration of harmful gases. Do you know how to do the installation and intermediate inspection of air duct? below

（1）先按濟南通風(fēng)管道設(shè)計圖紙并參照土建基準(zhǔn)線找出風(fēng)管標(biāo)高。

(1) Firstly, find out the elevation of air duct according to the design drawings of Jinan air duct and reference to the civil baseline.

（2）標(biāo)高確定后按風(fēng)管系統(tǒng)所在空間確定風(fēng)管支吊架形式，風(fēng)管支吊架形式及用料規(guī)格按照<<采暖通風(fēng)設(shè)計選用手冊>>(T607)選用。

(2) After the elevation is determined, the air duct support and hanger form shall be determined according to the space where the air duct system is located. The air duct support and hanger form and material specification shall be selected according to<>(T607).

（3）安裝吊架

(3) Installation hanger

（A）按風(fēng)管線找出吊桿敷設(shè)位置，單吊桿在風(fēng)管線上；雙吊桿按托盤的螺栓孔距或風(fēng)管的線對稱安裝。

(A) Find out the laying position of the suspender according to the center line of the air duct, and the single suspender is on the center line of the air duct; The double suspenders shall be installed symmetrically according to the bolt hole distance of the tray or the centerline of the air duct.

（B）吊桿根據(jù)吊件形式可焊在吊件上，也可掛在吊件上。

(B) The suspender can be welded or hung on the hanger according to the form of hanger.

（C）立管管卡安裝時，應(yīng)先把上面的吊件固定好，再用錘在得吊線，下面的管卡按所吊的線進行固定。

(C) When installing the riser clamp, the upper hanger shall be fixed first, and then the hanging line shall be obtained by hammering in the center. The lower clamp shall be fixed according to the hanging line.

（D）當(dāng)風(fēng)管較長時，需安裝一排支架時，可先固定兩端，再用拉線法安裝其它支架。

(D) When the air duct is long and a row of supports need to be installed, fix the two ends first, and then install other supports with the pull wire method.

（E）濟南通風(fēng)管道安裝須設(shè)置固定支架。

(E) Fixed supports must be provided for the installation of ventilation pipes in Jinan.

（F）支吊架的予埋件或膨脹螺栓埋入部分不得有油漆，并去除油污。（G)支吊架不得安裝在風(fēng)口、閥門、檢查孔處，以免妨礙操作，吊架不得直接吊在法蘭上。

(F) Embedded parts of supports and hangers or embedded parts of expansion bolts shall be free of paint and oil stain shall be removed. (G) The support and hanger shall not be installed at the air outlet, valve and inspection hole to avoid hindering the operation. The hanger shall not be directly hung on the flange.

（G)保溫風(fēng)管不得直接與支架接觸，應(yīng)墊上堅固的木條，厚度與保溫層相同。

(G) The insulation air duct shall not directly contact with the support, but shall be padded with solid wooden strips with the same thickness as the insulation layer.

（H）風(fēng)管支吊架間距應(yīng)符合設(shè)計要求，如無設(shè)計要求，對不保溫水平風(fēng)管：直徑或邊長小于400mm間距不應(yīng)大于四米；直徑或邊長大于400mm間距不應(yīng)大于三米；對不保溫垂直風(fēng)管支架間距不大于四米，且每根立管不少于兩個支架。

(H) The spacing between supports and hangers of air duct shall meet the design requirements. If there is no design requirement, the spacing of uninsulated horizontal air duct shall not be greater than four meters if its diameter or side length is less than 400 mm; The distance between diameters or side lengths greater than 400mm shall not be greater than 3m; The spacing between supports of uninsulated vertical air duct shall not be more than four meters, and each riser shall have at least two supports.
