Nowadays, many ventilation ducts are installed in buildings. When two vertical ventilation ducts arranged side by side are installed in a building with a floor clearance exceeding 4 meters, two supports need to be set for each air duct on each floor. The traditional installation method of air duct supports is to fixedly install a portal support on the ground of each floor, and at the same time fixedly install an air duct hanger at the top plate of each floor, and support the air duct through the portal support and the air duct hanger. However, this installation method requires drilling holes in the floor slab to install expansion fastening nuts to fix the air duct hanger, resulting in a large amount of high-altitude operation work, having potential safety hazards, and consuming materials, with high production costs.
