Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to an integrated system for air ducts to pass through walls and an installation method. Background Art

[0002] At present, the gap between the casing and the duct at the wall penetration position of the air duct is usually filled with fireproof plugging materials, such as asbestos wire, but there are gaps between these fireproof plugging materials. When a fire occurs, harmful smoke can still pass through the firewall from the gap of the fireproof plugging materials, causing safety accidents. The process of the air duct passing through the firewall fire partition is: civil engineering hole → duct processing and duct installation → casing processing → casing installation → casing outer side plugging → casing inner side plugging → outer surface treatment. This traditional process is complicated and requires three to four repeated constructions on the wall, which consumes a lot of labor. Since the plugging of the inside and outside of the casing requires the cooperation of the electromechanical and civil engineering units, the outside of the casing will squeeze the casing during plugging, resulting in a large deviation in the distance between the casing and the air duct, and the plugging effect is often poor. When the traditional process is used for thin walls, the phenomenon of the casing being squeezed by the outside becomes particularly obvious, and the plugging effect is greatly reduced. Summary of the invention

The problem of insufficient contact surface between the wall and the air duct for blocking is solved by setting a first steel plate in the shaped steel plate. The problem that the relative position of the air duct and the wall is difficult to adjust and fix is ​​solved by setting a position adjustment locking device on the second steel plate.
