Description

Technical Field

[0001] This utility model relates to the field of fireproof air duct technology, specifically a single-sided color steel composite fireproof air duct. Background Technology

[0002] Fire-resistant ducts are key fire-resistant components in building ventilation systems used to prevent the spread of fire and smoke. They are mainly used in smoke control systems or ventilation ducts that pass through fire compartments.

[0003] Most existing fireproof air ducts are connected and fixed using rigid flange structures. Although flanges can ensure the sealing of the connection between pipes, leakage can still occur at the joints. Utility Model Content

[0004] The purpose of this utility model is to provide a single-sided color steel composite fireproof air duct. The two independent expansion and deformation cavities can be filled with fireproof expansion material. In the event of a fire, the high temperature triggers the material to expand, filling the splicing gaps and blocking the penetration of smoke and flames. The structural design of the folding plate and the inner baffle can form a labyrinth-like sealed path, further blocking the spread of smoke, which can solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-sided color steel composite fireproof air duct, comprising a square air duct, wherein the square air duct comprises an aluminum foil plate and a color steel fireproof plate, and a composite fiber board is provided between the aluminum foil plate and the color steel fireproof plate, wherein a reinforcing keel is provided inside the composite fiber board, and the reinforcing keel is connected and fixed to the aluminum foil plate and the color steel fireproof plate by screws respectively, and a transition lock frame is provided at both ends of the square air duct, and a sealing gasket is provided between the transition lock frame and the square air duct, wherein the sealing gasket is in contact with the aluminum foil plate.

[0006] Preferably, the square air duct is provided with horizontal rails on both sides, and the horizontal rails are connected to the color steel fireproof plate by screws. The outer side of the horizontal rail is provided with a sliding buckle.

[0007] With the above solution, the sliding clip can slide and adjust along the horizontal rail, which is suitable for pre-drilling operations with different spacing specifications, reduces the installation accuracy requirements, and adapts to complex pipeline layouts.

[0008] Preferably, the sliding buckle has a U-shaped metal hanger inside, which is connected to the sliding buckle through a slot. A locking bolt is provided above the sliding buckle, which extends through the sliding buckle to the surface of the horizontal rail.

[0009] Preferably, both ends of the horizontal rail are provided with flanges, which are welded to the color steel fireproof plate.

[0010] The above solution involves welding flange sleeves at the ends, which is compatible with traditional flange connection requirements and improves adaptability.

[0011] Preferably, the adapter lock frame is combined with a square air duct through a splicing groove, and the interior of the adapter lock frame is provided with two expansion and deformation cavities, and a partition is provided between the expansion and deformation cavities.

[0012] Through the above scheme, the expansion and deformation cavity can be filled with fireproof expansion material. When a fire occurs, the high temperature triggers the material to expand, fill the splicing gaps, and block the penetration of smoke and flames.

[0013] Preferably, an integrally formed folding plate is provided on the outer side of the expansion and deformation cavity, and an inner baffle is provided at the opening at the bottom of the expansion and deformation cavity, wherein the aluminum foil plate extends to the inner side of the inner baffle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, based on flange connection, uses splicing grooves to insert into the end of the air duct, combined with sealing gaskets to achieve physical sealing. The interior is set with two independent expansion and deformation cavities that can be filled with fireproof expansion material. In the event of a fire, the high temperature triggers the material to expand, filling the splicing gaps and blocking the penetration of smoke and flames. The structural design of the folding plate and the inner baffle can form a labyrinth-like sealing path, further blocking the spread of smoke.

[0016] 2. In this utility model, the sliding buckle can be adjusted along the horizontal rail, which is suitable for pre-drilling operations with different spacing specifications. Then, the metal hanger is connected to the slot of the sliding buckle to achieve quick positioning, reduce the installation accuracy requirements, and adapt to complex pipeline layouts.
