Detailed explanation of door-to-door design and installation of smoke exhaust pipe process steps

风管组装：风管较短可以一次性在地面组装，风管较长可依据安装场地情况分段组装。组装时应尽量调整风道的度和水平度，避免风管扭曲或上下起波，左右摆龙，每段风道不宜超过10m。组装时，垫片应垫平，法兰螺栓应均匀拧紧，螺母帽均朝向同一方向。

Air duct assembly: the short air duct can be assembled on the ground at one time, and the long air duct can be assembled in sections according to the situation of the installation site. During assembly, the center degree and levelness of air duct shall be adjusted as much as possible to avoid air duct distortion or up and down wave, left and right swing dragon, and each section of air duct shall not exceed 10m. During assembly, the gasket shall be leveled, the flange bolt shall be tightened evenly, and the nut cap shall face the same direction.

风管就位：先检查全部支架的水乎度、标高、牢固程度。风管就位一般使用直接和吊具两种方式。如果风管断面较小位置又很低的可采用人工就位方法，只需搭设简易脚手架即可。当风管断面较大且管段较长时，可采用滑轮、倒链、大绳等方法吊装。为了便于风道就位，一般多采用将风道吊在脚手架上，然后再将其抬放在风道支架上的方法。脚手架应沿其风道长度方向搭设，高度和位置应适合施工操作，吊装顺序应先干管后支、立管。

Air duct in place: first check the water level, elevation and firmness of all supports. In general, two methods are used to place the air duct: direct and spreader. If the cross-section of the air duct is small and low, the manual positioning method can be used, only the simple scaffold can be erected. When the cross-section of the air duct is large and the pipe section is long, the pulley, chain block, rope and other methods can be used for hoisting. In order to facilitate the positioning of air duct, the method of hanging the air duct on the scaffold and then lifting it on the air duct support is generally adopted. The scaffold shall be erected along the length direction of its air duct, and the height and position shall be suitable for construction operation. The hoisting sequence shall be from main pipe to support and riser.

风道调直：就位在支架上的风道，应拨正位置，调整风道横平竖直，然后再按图集要求固定。

Air duct straightening: the air duct placed on the bracket shall be straightened, horizontally and vertically adjusted, and then fixed according to the requirements of the atlas.
