Embodiment

[0014] Embodiment: A kind of composite glass wool board air duct construction method, comprises the following steps:

[0015] 1) Glue the corner line and closing line of the air duct tightly, without cracks and gaps, without holes in the pipe wall, and use aluminum foil tape to make no seams along the length of the air duct;

[0016] 2) When the width of the air duct is greater than 1 meter, each section of the air duct shall be provided with 1 pair of internal supports; if the width is greater than 1.6 meters, each section of the air duct shall be provided with 2 pairs of internal supports, and all perforated seams on the duct wall shall be tightly sealed with sealing tape Blocking;

[0017] 3) The end of the air duct is lapped with the lining flange connector, and the overlapping parts are tightly bonded with glue, and the inner side of the air duct and the lining flange connector are firmly compacted with plastic insulation nails;

[0018] 4) Steel circles with external th...

Abstract

The invention discloses a construction method for a compound glass wool board air pipe, which adopts lining flange connection to successfully avoid cold-heat bridge cutoff easily caused at the joint of a traditional flange butting air pipe, and eliminates condensation and moldiness. Inner air pipe supports and lining flange connectors are trusses composed of flat steel and round steel with reinforcing ribs (grooves), and the strength problem of the compound glass wool board air pipe is conveniently solved, so that consumption of steel in connection of the air pipe is reduced, and accessory cost is reduced. Galvanized hanger rods are directly welded on the lining flange connectors, hanger cross arms are completely not needed, and reinforcement aluminum foils are directly pasted outside air pipe joints, so that the appearance of the air pipe is continuous, smooth, square, attractive and elegant, and various requirements of open installation, concealed installation and the like can be met.

Description

technical field [0001] The invention belongs to pipelines, in particular to a construction method for composite glass wool board air ducts. Background technique [0002] Since the mid-1990s, composite glass wool air ducts have been gradually popularized in my country due to their advantages of light weight and low cost. The traditional composite glass wool board air duct adopts angle steel flange or steel plate flange joints, the inner support adopts multiple single rod supports, and the external suspension adopts angle steel or special-shaped light steel cross-arm support. Problems such as bridge condensation, mildew, messy appearance are not suitable for surface installation, and cannot adapt to larger cross-sectional sizes. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a simple structure, which adopts a lined flange connection, avoids the hot and cold bridge breakage...
