Sichuan magnesium smoke duct board air duct flange bolts should be galvanized material, using cold galvanized material shall not be. The wind pipe diameter or length less than or equal to 1000mm, the bolt specifications for M8; more than 1000mm, is M10. On both sides of the flange bolts should be galvanized heating washer and nut should be tightened evenly on the same side. Flange surface should be smooth, neat height. The installation should be stopped when the wind pipe port closed.

In order to ensure the tightness of flange interface between the flanges should be padded. Smoke exhaust air duct flange gasket should use incombustible materials. The two flange, flange on the first is put on several galvanized bolt and a nut, do not tighten. Then use the spikes into not wear bolt holes, two holes until all the bolts are broken, wear after the bolt tightening. In order to avoid slipping bolts, fastening bolts should be tightened evenly cross gradually. Air pipe connection is good, should be based on both ends of the flange shall prevail, check cable duct connection is flat. Sichuan magnesium plate installed wind pipe connecting lifting smoke duct: according to the construction site, a section of a duct can be placed on the bracket by joint, can also be connected to a certain length on the ground, and then the integral lifting method in place. Sichuan magnesium smoke duct plate length or diameter of more than 1250mm of wind pipe hoisting shall not exceed 2 knots, length or diameter less than 1250mm wind pipe combination lifting not more than 3 knots. The wind pipe on the hanger on, where will the tray and connect the boom, confirm the wind has been stable, can untie the rope buckle.

Sichuan glass magnesium plate installation segment installation exhaust air duct for hanging pulley or inconvenience due to space restrictions, can not be lifting, can be segmented with the rope to the scaffold tube wind, and carried on the support of the flange is gradually installed. The main air duct system of 3.5.3 tube after installation, not connected to air outlet and pipe before the main pipe tightness test of duct system based.
