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

風管組裝：風管較短可以一次性在地面組裝，風管較長可依據(jù)安裝場地情況分段組裝。組裝時應(yīng)盡量調(diào)整風道的度和水平度，避免風管扭曲或上下起波，左右擺龍，每段風道不宜超過10m。組裝時，墊片應(yīng)墊平，法蘭螺栓應(yīng)均勻擰緊，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.

風管就位：先檢查全部支架的水乎度、標高、牢固程度。風管就位一般使用直接和吊具兩種方式。如果風管斷面較小位置又很低的可采用人工就位方法，只需搭設(shè)簡易腳手架即可。當風管斷面較大且管段較長時，可采用滑輪、倒鏈、大繩等方法吊裝。為了便于風道就位，一般多采用將風道吊在腳手架上，然后再將其抬放在風道支架上的方法。腳手架應(yīng)沿其風道長度方向搭設(shè)，高度和位置應(yīng)適合施工操作，吊裝順序應(yīng)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.

風道調(diào)直：就位在支架上的風道，應(yīng)撥正位置，調(diào)整風道橫平豎直，然后再按圖集要求固定。

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.
