[0005] A structure for a wind pipe passing through a roof includes a wind pipe arranged in a building main body. A penetration hole is opened on the roof of the building main body, and the wind pipe penetrates through the penetration hole. A sealing plate is arranged at the penetration hole above the roof, a waterproof boss is arranged above the sealing plate, a sound-absorbing cotton is arranged between the waterproof boss and the wind pipe, a centering ring support is arranged on the top surface of the waterproof boss to support around the wind pipe, a waterproof jacket is clamped above the waterproof boss to seal around the wind pipe, and the bottom of the waterproof jacket and the waterproof boss are sealed by silica gel.

[0006] Preferably, the sealing plate is a steel plate, and a through hole adapted to the wind pipe is opened in the middle.

[0007] Preferably, the waterproof boss is a convex-shaped concrete structure, there is a gap between the convex-shaped concrete structure and the wind pipe, and its top is a frustum of a cone.

[0008] Preferably, the centering ring support includes a ring support and an adjusting component. The ring support is a ring-shaped structure made by bending an elastic angle steel and is fixed on the top surface of the frustum of a cone, and multiple groups of adjusting components are uniformly arranged on the ring support.

[0009] Preferably, the adjusting component includes an adjusting stud and an adjusting nut. A plurality of threaded holes are uniformly arranged on the ring support, the adjusting stud is threadedly connected in the threaded hole, and an adjusting nut is threadedly connected to one end outside the ring support.

[0010] Preferably, the waterproof jacket is a shell structure with a through hole at the top. The inner side of the top of the waterproof jacket is adapted to the wind pipe, and the inner side of the bottom is adapted to the frustum of a cone.

[0011] Preferably, a sealing ring is provided between the through hole and the air duct.

[0012] Preferably, the waterproof jacket is formed by hinging a first flap and a second flap. The first flap and the second flap are clamped and fitted on the outer side of the air duct and are connected into a housing structure through a connecting buckle.

[0013] Preferably, a plurality of rivets are transversely arranged on the outer side of the air duct, and a fixing groove is formed on the inner sides of the tops of the first flap and the second flap, and the rivets are stuck in the fixing grooves.

Detailed Embodiment

[0018] The following further describes the present utility model with reference to the drawings:

[0019] As Figure 1 and Figure 2 shown, a structure for an air duct passing through a roof includes an air duct 1 arranged in a building main body. A through hole 20 is formed in the roof 2 of the building main body, and the air duct 1 passes through the through hole 20. A sealing plate 3 is arranged above the roof 2 at the through hole 20. The sealing plate 3 is a steel plate, and a through hole adapted to the air duct 1 is formed in the middle. The sealing plate 3 is the first-level seal of the through hole.

[0020] Above the sealing plate 3, a waterproof boss 4 is provided. The waterproof boss 4 serves as the second-stage seal for the through-hole. A sound-absorbing cotton 5 is provided between the waterproof boss 4 and the air duct 1 to reduce the noise impact of the air duct 1 on the roof 2. On the top surface of the waterproof boss 4, a centering ring support 6 is provided to support the periphery of the air duct 1. The centering ring support 6 can not only support the air duct 1 but also perform centering adjustment on the air duct 1 to ensure the verticality of the air duct 1, facilitating subsequent clamping and sealing with a waterproof jacket. The centering ring support 6 includes a ring support 60 and an adjustment component 61. The ring support 60 is a ring-shaped structure made by bending an elastic angle steel, and the ring support 60 is fixedly installed on the top surface of the frustum 40 through fasteners. A plurality of groups of adjustment components 61 are evenly arranged on the ring support 60. The adjustment component 61 includes an adjustment stud 610 and an adjustment nut 611. A plurality of threaded holes are evenly provided on the ring support 60. The adjustment stud 610 is threadedly connected in the threaded hole, and an adjustment nut 611 is threadedly connected to one end outside the ring support 60.

[0021] Above the waterproof boss 4, a waterproof jacket 7 is clamped to seal the periphery of the air duct 1. The bottom of the waterproof jacket 7 is sealed with the waterproof boss 4 through silica gel 8. The waterproof jacket 7 serves as the third-stage seal for the through-hole and can also fix the air duct 1. The waterproof boss 4 is a convex-shaped concrete structure. There is a gap between the convex-shaped concrete structure and the air duct 1, and its top is a frustum 40.

[0022] The waterproof jacket 7 is a shell structure with a through-hole at the top. The inner side of the top of the waterproof jacket 7 is adapted to the air duct 1, and the inner side of the bottom is adapted to the frustum 40. A sealing ring 9 is provided between the through-hole and the air duct 1. The sealing ring 9 serves as the fourth-stage seal for the through-hole. The waterproof jacket 7 is formed by hinging a first flap 70 and a second flap 71, which is convenient for clamping and installing on the air duct 1. The first flap 70 and the second flap 71 are clamped and fitted on the outer side of the air duct 1 and are connected into a shell structure through a connecting buckle.
