Hanging installation method for air pipe of steel grid structure

The invention relates to a steel grid structure air pipe hanging installation method, which belongs to the technical field of air pipe installation, and comprises the following steps: S1, prefabricating a support hanger: measuring the pre-installation position of the support hanger, and determining the size of the support hanger according to the size of an on-site air pipe in a grid to be completed before prefabrication; s2, a support hanger is installed on the steel net frame through a cable-stayed part and a P-type pipe bundle; S3, an air pipe is installed on the support hanger; the cable-stayed parts and the P-shaped pipe bundles are used for connecting the support hanger and the steel net rack, the problems that the distance between rod pieces of the steel net rack is too large, and rooting cannot be achieved are solved, the support hanger can be installed on a horizontal rod piece and is also suitable for an inclined rod piece, and compared with the mode that the support hanger and the steel net rack are
