镀锌钢板风管有什么样的作用？

一是为固定防松动，风管作用，与砼更好的结合在一起；二为战时防毒气沿管壁或套管壁渗入防护区，所以套管密闭肋的材质，风管，厚度，风管型号，高度都有规范要求。还有设计要求。因为套管密闭肋，根据设计要求是分一型二型还有三型的。就是套管密闭肋分一块两块还有三块的。甚套管密闭肋，没有在套管的顶端。因为套管出墙，套管密闭肋就会在墙里面的。所以套管密闭肋的作用不是很大。风管可以直接与通风套管焊接在一起就可以了。如果不方便的话，那么可以把通风套管接出一段。

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.

是将在地面上连接好的风管，一般可接长10~20m左右，用倒链或滑轮将风管升吊架上的方法。即挂好倒链或滑轮，再用麻绳将风管捆绑结实（一般绳索不直接捆绑在风管上，而是用长木板插入麻绳受力部位，或用长木板拖住风管底部）四周用软性材料垫牢。起吊风管离地200~300mm时，应仔细检查倒链或滑轮受力点和捆绑风管的绳索、绳扣是否牢靠，风管是否正确，没问题后继续吊装。

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.

镀锌钢板风管放在支、吊架后，将所有托架和吊杆连接好，确认风管稳固后，方可解开绳扣。风管分节安装：对于不便悬挂滑轮或因受场地限制，不能进行吊装时，可将风管分节用绳索拉到脚手架上，然后抬到支架上对正法兰逐节安装。

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.

各类风管部件及操作机构的安装，应能保证其正常的使用功能，并便于操作。防火阀的安装方向、位置应正确。防火阀直径或长边尺寸大于等于630mm时，宜设独立支、吊架。防火分区隔墙两侧的防火阀，距墙表面不应大于200mm。排烟阀（口）及手控装置（包括预埋套管）的位置应符合设计要求。

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.
