Description

Technical Field

[0001] The utility model belongs to the technical field of air duct installation, and particularly relates to an air duct hanger installation structure. Background Art

[0002] An air duct is a metal pipe used for air supply, smoke exhaust, etc. The cross-section perpendicular to its own axis is usually a rectangular structure. An insulation and fireproof structure is installed on the air duct. The existing insulation and fireproof structure usually includes rock wool boards, fireproof boards, keel rings and fireproof sealing plates. The rock wool boards are coated on the outer peripheral surface of the air duct and are arranged in multiple sections along the axial direction of the air duct. The keel rings are installed between adjacent two sections of rock wool boards and are coaxially arranged with the air duct. The fireproof boards are coated on the outer peripheral surface of the rock wool boards. The ends of the fireproof boards extend to the keel rings and are connected to the keel rings by screws. Adjacent two sections of fireproof boards are butted at the keel rings. The fireproof sealing plates are installed at the butting place by screws to block the joints of adjacent two sections of fireproof boards. Then, the air duct installed with the insulation and fireproof structure is hoisted on a beam or a floor by a hanger. During the air supply and smoke exhaust processes of the air duct, vibrations are generated, and the air duct installed with the insulation and fireproof structure is prone to displacement on the hanger, with poor reliability.
