一是為固定防松動，風管作用，與砼更好的結合在一起；二為戰時防毒氣沿管壁或套管壁滲入防護區，所以套管密閉肋的材質，風管，厚度，風管型號，高度都有規范要求。還有設計要求。因為套管密閉肋，根據設計要求是分一型二型還有三型的。就是套管密閉肋分一塊兩塊還有三塊的。甚套管密閉肋，沒有在套管的頂端。因為套管出墻，套管密閉肋就會在墻里面的。所以套管密閉肋的作用不是很大。風管可以直接與通風套管焊接在一起就可以了。如果不方便的話，那么可以把通風套管接出一段。

First, for the purpose of fixing and preventing looseness, the air duct is better combined with the concrete; Second, in wartime, anti-virus gas seeps into the protection area along the pipe wall or casing wall, so the material, air duct, thickness, air duct model and height of casing sealing rib have specification requirements. There are design requirements. Because the casing sealing rib is divided into one type, two types and three types according to the design requirements. The casing sealing rib is divided into one, two and three. Even the casing sealing rib is not at the top of the casing. Because the casing goes out of the wall, the sealing rib of the casing will be in the wall. Therefore, the role of casing sealing rib is not great. The air duct can be directly welded with the ventilation sleeve. If it is inconvenient, connect a section of the ventilation sleeve.

是將在地面上連接好的風管，一般可接長10~20m左右，用倒鏈或滑輪將風管升吊架上的方法。即掛好倒鏈或滑輪，再用麻繩將風管捆綁結實（一般繩索不直接捆綁在風管上，而是用長木板插入麻繩受力部位，或用長木板拖住風管底部）四周用軟性材料墊牢。起吊風管離地200~300mm時，應仔細檢查倒鏈或滑輪受力點和捆綁風管的繩索、繩扣是否牢靠，風管是否正確，沒問題后繼續吊裝。

It is a method that the air duct connected on the ground can be extended by about 10 ~ 20m, and the air duct can be lifted to the hanger with chain block or pulley. That is, hang the chain block or pulley, and then bind the air duct firmly with hemp rope (generally, the rope is not directly tied to the air duct, but inserted into the stressed part of the hemp rope with a long wooden board, or dragged the bottom of the air duct with a long wooden board) and pad it firmly with soft materials around. When lifting the air duct 200 ~ 300mm above the ground, carefully check whether the force point of the chain block or pulley, the rope and rope buckle binding the air duct are firm, and whether the center of gravity of the air duct is correct. Continue the lifting after there is no problem.

鍍鋅鋼板風管放在支、吊架后，將所有托架和吊桿連接好，確認風管穩固后，方可解開繩扣。風管分節安裝：對于不便懸掛滑輪或因受場地限制，不能進行吊裝時，可將風管分節用繩索拉到腳手架上，然后抬到支架上對正法蘭逐節安裝。

After the galvanized steel sheet air duct is placed on the supports and hangers, connect all brackets and suspenders, and untie the rope buckle after confirming that the air duct is stable. Segmented installation of air duct: when it is inconvenient to hang the pulley or cannot be hoisted due to site constraints, the segmented air duct can be pulled to the scaffold with rope, and then lifted to the support to align the flange for installation section by section.

各類風管部件及操作機構的安裝，應能保證其正常的使用功能，并便于操作。防火閥的安裝方向、位置應正確。防火閥直徑或長邊尺寸大于等于630mm時，宜設獨立支、吊架。防火分區隔墻兩側的防火閥，距墻表面不應大于200mm。排煙閥（口）及手控裝置（包括預埋套管）的位置應符合設計要求。

The installation of various air duct components and operating mechanisms shall ensure their normal use function and facilitate operation. The installation direction and position of fire damper shall be correct. When the diameter or long side size of the fire damper is greater than or equal to 630mm, independent supports and hangers should be set. The fire dampers on both sides of the partition wall of the fire compartment shall not be more than 200mm from the wall surface. The position of smoke exhaust valve (port) and manual control device (including embedded casing) shall meet the design requirements.
