Dongguan Spiral Duct uses integrated hoisting technology
Dongguan spiral duct is used in many exhaust systems. The air-conditioning air supply ducts in the competition hall are double-layer heat-preserving circular spiral air ducts 1400mm and 1600mm, a total of 12, the air supply method uses 126 630mm spherical nozzles to supply air from the surrounding to the hall, and spiral air Tube hoisting technology.
The layout of the spiral duct and the spherical nozzle is shown in the 2 construction process. Install the duct bracket, the classification number of the duct, set up the duct assembly platform → install the duct flange → suspend the duct to the platform for assembly → measure the main horizontal center line of the duct → Measure into the center line of the exhaust vent → the tee opening of the vent → the installation and insulation of the short duct of the vent → the installation of the vent → the installation of the vent bracket → the installation of the hoop bracket → the installation of the hoist → the installation of the reinforcement bracket and the lifting rope → the duct Air duct bracket installation and adjustment. 3 Preparation for construction 1) Because the air duct is installed below the truss 25m above the ground, the span between the 2 榀 steel truss beams is 10.5m, and there is no connecting channel in the middle.
