Description

Technical Field

[0001] The embodiment of the utility model relates to the field of construction engineering, and in particular to a building air duct device. Background Art

[0002] The new smoke control and exhaust regulations eliminate the previous practice of using civil ducts for ventilation. Instead, they require that mechanical pressurized air systems utilize piped ventilation, specifically galvanized iron ducts. For typical residential and industrial buildings currently being designed and constructed, galvanized iron ducts are placed after the concrete ducts are poured on each floor. The maximum length of galvanized iron ducts is 3 meters, typically constructed from two connected sections. During installation, the galvanized iron ducts are lowered from the top of the concrete duct, secured with brackets on the top surface of the upper section, and then hung from top to bottom. The weight of the ducts can cause some deformation, compromising the smooth and reliable operation of the mechanical pressurized air supply system. Sufficient space must be left between the ducts for installation, which increases the duct area. Utility Model Content

[0027] Figure 1、 Figure 2 A building air duct device in one embodiment of the present invention is shown, which includes an air duct 80, multiple reinforcements, and an air duct 90; multiple reinforcements are installed on the periphery of the air duct 80 and protrude from the air duct 80, and the air duct 80 and the air duct 90 are cast together so that the reinforcements are embedded in the inner wall of the air duct 90.

[0028] The air duct 80 and the air duct 90 can be the same length. During the casting process of the air duct 90, the air duct 80 serves as a mold for forming the inner wall of the air duct 90 and is installed in the air duct 90. The air duct 90 is cast from steel bars and concrete. During the molding process, the concrete contacts the outer surface of the air duct 80 and solidifies, allowing the reinforcement to be embedded in the inner wall of the air duct 90. The reinforcement is embedded in the inner wall of the air duct 90 to stabilize the overall structural stability of the air duct 80, thereby allowing the air duct 80 to be cast entirely in the air duct 90 and reducing the area of ​​the air duct 90. During the molding process of the air duct 90, the reinforcement ensures the structural stability of the air duct 80 and ensures that the molded structure of the air duct 90 meets the design specifications. The reinforcement member can be a rib 81 installed on the side of the air duct 80. The rib 81 is long and protrudes 25 mm from the side of the air duct 80. The length is the same as the air duct 80. In one embodiment, the ribs 81 on the side of the air duct 80 are parallel to each other. The multiple ribs 81 can be installed on the side of the air duct 80 in a vertical or horizontal direction, or at a predetermined angle, such as each rib 81 and the top surface of the air duct 80. In another embodiment, the ribs 81 on the side of the air duct 80 are staggered. The multiple ribs 81 can be perpendicular to each other or arranged at a predetermined angle, such as in a "M" shape. In another embodiment, the spacing between the multiple ribs 81 on the same side can be uniform, ranging from 100 to 250 mm. When the spacing is uniform, the force on the side of the air duct 80 is more uniform.

[0029] In one embodiment of the present invention, each of the ribs 81 is provided with a plurality of through holes 811, and fasteners are provided in the through holes 811, wherein the fasteners can be connected to the through holes 811 individually or inserted into a plurality of adjacent through holes 811, and can be used to strengthen the connection between the air duct 80 and the air duct 90. Alternatively, before pouring, the through holes 811 can be connected and fixed to the steel bars in the air duct 90 by bundling, which can also strengthen the connection between the air duct 80 and the air duct 90. In one implementation, the fasteners increase the structural strength of the air duct 80 by connecting adjacent ribs 81 together, and can also increase the contact area between the air duct 80 and the concrete when pouring with the air duct 90, thereby increasing the connection strength. In another implementation, the plurality of through holes 811 on each of the ribs 81 are arranged at equal intervals, and the fasteners are steel bars, which are inserted into the through holes 811 at the same position on the ribs 81 on the same side of the air duct 80 to enhance the structural stability of the air duct 80; and before pouring the air duct 90, the fasteners are bundled together with the steel bars in the air duct 90 and then poured to enhance the connection between the air ducts 80 and the air ducts 90.

[0030] Among them, the connection between the rib plate 81 and the air duct 80 can be achieved by welding, gluing and one-piece molding. In one implementation, the rib plate 81 is formed by bending the side of the air duct 80 outward, thereby integrating the rib plate 81 and the air duct 80 into an integrated molding to enhance the connection strength between the rib plate 81 and the air duct 80.

[0031] Among them, the structure of the rib 81 can be a hollow structure such as U-shaped, rectangular, triangular, etc., and both ends of the rib 81 extend to the boundary of the side of the air duct 80. Among them, the rib 81 adopts a hollow structure, which increases the structural strength of the air duct 80 while saving materials and reducing production costs.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
