The flange connecting bolts of Sichuan glass magnesium smoke control air duct board shall be hot-dip galvanized, and cold galvanized materials shall not be used. Air duct diameter or long side ≤ 1000mm, bolt specification is M8; if it is greater than 1000mm, it is M10. Both sides of flange bolts shall be heated with galvanized washers and tightened evenly. Nuts shall be on the same side. The flange end face shall be flat and neat in height. When the installation stops halfway, the air duct port shall be closed.


In order to ensure the tightness of the flange interface, there should be padding between the flanges. Non combustible materials shall be used for the flange gasket of smoke control air duct. During flange connection, align the two flanges first, put on several galvanized bolts and nuts, and do not tighten them temporarily. Then, insert a sharp object into the screw holes that cannot be threaded with bolts, and pry the two screw holes until all bolts are threaded, and then tighten the bolts. In order to avoid bolt slipping, tighten the bolts gradually and evenly according to the cross. The connected air pipes shall be subject to the flanges at both ends, and the air pipes shall be checked for straightness by pulling wires. Sichuan glass magnesium smoke control air duct board installation air duct extension hoisting: according to the situation of the construction site, the air duct can be placed on the support section by section, or connected to a certain length on the ground, and then the whole hoisting method is used in place. When the side length or diameter of the smoke control air duct board of Sichuan glass magnesium is greater than 1250mm, it shall not be more than 2 sections, and when the side length or diameter is less than 1250mm, it shall not be more than 3 sections. After the air duct is placed on the support and hanger, connect the tray and the suspender, and confirm that the air duct is stable and firm, then the rope buckle can be untied.


Installation of smoke control air duct board of Sichuan glass magnesium: when it is inconvenient to hang pulley or due to site restrictions, it is not possible to lift, the air duct can be pulled to the scaffold with rope rope, and then lifted to the support to align the flange for installation step by step. 3.5.3 after the main air pipe of the air duct system is installed and before connecting the air inlet and branch pipe, the tightness inspection of the air duct system shall be carried out mainly by the main pipe.
