Abstract
The invention discloses a method for constructing an insulating layer in an air duct made of an iron sheet. The method comprises the following steps: preparing before construction; distributing and fixing insulating nails; cutting an insulating plate; splicing the insulating plates; cutting and splicing an aluminum-foil glass fiber cloth layer; performing insulation treatment on the flange surface of the air duct; fixing the insulating nails with the insulating layer; and assembling brace rods. According to the method, the insulating layer is arranged inside the air duct, so that the insulating layer is prevented from being broken when the air duct is assembled, and noise generated when wind current in the air duct impacts the insulating layer can be greatly reduced; and the air duct made of the iron sheet can be intensively prefabricated, so that the productivity is greatly improved.
