Description

Technical Field

[0001] The present application relates to the technical field of air duct systems, and in particular to an air duct system and an assembled building containing the air duct system. Background Art

[0002] The air duct is a channel structure within a building for the circulation of indoor air and outside air. It is also connected to the fresh air system and air conditioning system for use.

[0003] Typically, except for pre-designed buildings, ventilation ducts are typically hung from the building's interior ceiling. Some buildings may conceal them with a suspended ceiling for aesthetic reasons. However, this method of installing ventilation ducts consumes interior space, particularly floor height, and compromises overall integrity. Furthermore, if slots are cut into the building to accommodate the ventilation ducts, this compromises the building's strength and safety. Utility Model Content

[0004] The purpose of the utility model of the present application is to improve the problem that the air duct system in the existing building occupies indoor space and has poor safety. The present application provides an air duct system and an assembled building containing the air duct system.

[0005] The air duct system provided in this application adopts the following technical solution:

[0006] An air duct system utilizes the cavity of the square steel tube frame support structure within the building as an air cavity. The air cavities of the interconnected square steel tube frame structures are interconnected, and the air cavities are connected to the air outlet of the outdoor fresh air system.

[0007] The square steel tube supporting structure is provided with an air outlet communicated with the air cavity.

[0008] This application also provides a prefabricated building using the following technical solution:

[0009] An assembled building, comprising the above-mentioned air duct structure, including a base frame, columns, beams, a base plate, a top plate, exterior wall panels and interior wall panels;

[0010] The columns are installed on the bottom frame, and the crossbeams are installed on top of the columns to form a frame support structure;

[0011] The columns and beams are not solid metal structures, but square steel tube structures;

[0012] The wind cavities of the connected columns and beams are interconnected;

[0013] The column air cavity is connected to the air outlet of the outdoor fresh air system;

[0014] The bottom plate is installed on the bottom frame, and the inner and outer wall panels are connected to each other and wrapped around the columns;

[0015] The top plate is installed on the beams and connected to the inner and outer wall panels;

[0016] A hole is provided at a position of the inner wall panel opposite to the air outlet.

[0017] Optionally, the interior of the air cavity is coated with a waterproof coating.

[0018] Optionally, a protective frame is installed at the opening where the inner wall panel communicates with the air cavity. The protective frame is made of plastic material and abuts against the inner wall of the air outlet. The protective frame covers the incision of the inner wall panel.

[0019] Optionally, elastic clips are fixed at both ends of the protective frame. The elastic clips are made of rubber. After the elastic clips are inserted into the air cavity, they pop out and cling to the inner wall of the air cavity. The elastic clips at the other end of the protective frame are pressed against the side wall of the inner wall panel.

[0020] Optionally, the air outlet and the protective frame of the crossbeam are both installed with a guide frame, and the guide frame is installed with a plurality of louvers, which can close the guide frame after being rotated.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] By utilizing the interior space of the building's square steel tube support structure as the air duct for the fresh air system, the air from the fresh air system is introduced into the building through the air cavity. This only requires designing the square steel tube frame support structure, eliminating the need to install additional ventilation ducts indoors, thus saving indoor space.

[0023] This type of air duct structure is used in prefabricated buildings. It does not require additional wall damage for pre-installation of the air duct, effectively improving the safety of the building while saving indoor space.

[0024] The waterproof coating in the air cavity can effectively increase the service life of the square steel pipe. At the same time, it cooperates with the protective frame to effectively reduce the penetration of moisture into the inner wall panel fault, thereby increasing the service life of the inner wall panel.

[0025] By setting the guide frame, on the one hand, the air outlet can be visually shielded, and on the other hand, the opening and closing of the air duct can be controlled by the louver, and the wind direction can also be controlled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiments of the present application disclose an air duct system and an assembled building containing the air duct system.

[0033] refer to Figure 1 、 Figure 2 and Figure 3 The prefabricated building containing the air duct system includes a frame structure 1 for support, a bottom plate 2, a top plate 3, an inner wall panel 4 and an outer wall panel 5.

[0034] The frame structure 1 comprises a base frame 11, columns 12, and crossbeams 13. The columns 12 are vertically mounted on the base frame 11 using ribs and bolts, with welding providing additional support for securing. Crossbeams 13 are mounted on top of the columns 12 and similarly connected to each other using ribs and bolts, with welding providing additional support for securing. Both the crossbeams 13 and the columns 12 are constructed of square steel tubes, with the crossbeams 13 also reinforced with square steel tubes.

[0035] The bottom panel 2 is mounted on the bottom frame 11, while the interior and exterior wall panels 4 and 5 are mounted on both sides of the columns 12, wrapping around them. The interior wall panels 4 form the interior wall panels. The top panel 3 is slotted at the bottom, aligned with the square steel pipe structure. The top panel 3 is mounted on the crossbeam 13 and attached to the interior and exterior wall panels 4 and 5.

[0036] The internal space of the crossbeam 13 and the column 12 is an air cavity 121. The air cavities 121 of adjacent crossbeams 13 and columns 12 are connected to each other, and the two ends of the crossbeam 13 are closed. The air cavity 121 is connected to the air outlet of the outdoor fresh air system. The air cavity 121 of the column 12 is provided with an air outlet 122 facing the indoor direction, and the air outlet 122 of the crossbeam 13 is provided at the bottom. The inner wall panel 4 is provided with a hole at the position opposite to the air outlet 122 to avoid the opening. The inside of the air cavity 121 is coated with a waterproof coating, and the inner wall panel 4 is provided with a protective component 6 for protecting the inner wall panel 4 at the opening facing the air outlet 122.

[0037] By utilizing the internal space of the square steel tubes within the frame structure 1 of the prefabricated building, an air cavity 121 is formed and interconnected. This allows the square steel tubes to not only serve as the building's support frame but also to blow the air generated by the fresh air system into the building through the internal space structure. This reduces the need for additional ventilation ducts, saves space within the building, and eliminates the need to cut grooves in the wall for burying ventilation ducts, thereby improving structural safety. The waterproof coating provided within the air cavity 121 can effectively enhance the protection of the columns 12 and beams 13. The protective assembly 6 can also effectively enhance the protection of the interior wall panels 4.

[0038] refer to Figure 3 The protective component 6 includes a protective frame 61 and an elastic card plate 62. The protective frame 61 is a frame structure made of plastic material, which is inserted into the opening where the inner wall panel 4 is connected to the air cavity 121. The circumferential outer wall abuts against the inner wall of the air outlet 122 of the column 12, and the protective frame 61 blocks the incision of the inner wall panel 4. The elastic card plate 62 is made of rubber material and is fixed at both ends of the protective frame 61. After the elastic card plate 62 penetrates into the air cavity 121, it will pop out and reset and cling to the inner wall of the air cavity 121, and the elastic card plate 62 at the other end of the protection is tightly abutted against the side wall of the inner wall panel 4. A guide component 7 for guiding the blown wind is installed at the air outlet 122 of the beam 13 and at the end of the protective frame 61 away from the column 12.

[0039] By inserting the protective frame 61 into the opening of the inner wall panel 4 and installing it in the air cavity 121, the inner wall panel 4 is shielded and protected, which reduces the occurrence of blown moisture wetting the inner wall panel 4, thereby improving the protection effect and service life of the inner wall panel 4.

[0040] refer to Figure 3 and Figure 4 The guide assembly 7 includes a guide frame 71 and louvers. The guide frame 71 is installed on the air outlet 122 of the crossbeam 13 and the protective frame 61. There are multiple louvers, all of which are rotatably connected to the inner wall of the guide frame 71, and the rotation axes of the louvers are parallel to each other. After the louvers rotate, the guide frame 71 can be closed. An adjustment cavity is provided on the inner wall of one side of the guide frame 71. The rotation axis of the louver is located in the adjustment cavity and is fixedly connected to an adjustment gear 711. The multiple adjustment gears 711 in the adjustment cavity are all engaged with the same toothed belt, and the toothed belt is in a tensioned state. The guide frame 71 is provided with an adjustment hole connected to the adjustment cavity. The toothed belt is fixed with an adjustment rod, and the adjustment rod extends from the adjustment hole. The adjustment rod is threadedly connected to a positioning sleeve adjustment rod 7222. The part of the positioning sleeve adjustment rod 7222 in the adjustment cavity is fixed with a clamping ring plate 7223, and the clamping ring plate 7223 can be pressed tightly against the inner wall of the adjustment cavity.

[0041] After installation, the guide frame 71 can guide the air flowing out of the air outlet 122 via the louvers. Simultaneously, the sliding adjustment rod can be used to rotate the toothed belt, thereby adjusting the rotation angle of the louvers and controlling the rotation of multiple louvers. After position adjustment, the louvers can be fixed by rotating the positioning sleeve adjustment rod 7222 to tighten the pressure ring plate 7223 against the inner wall of the adjustment chamber, thereby improving the efficiency of adjusting the direction of the air flowing out of the air outlet 122.

[0042] The air duct system and prefabricated building incorporating the same employ the following principles: The internal space within the square steel tubes of the prefabricated building's columns 12 and beams 13 serves as an air cavity 121. After connecting to the fresh air system, air is delivered to the interior of the building through an air outlet 122. This eliminates the need for additional ventilation ducts or wall slots for ducting, saving interior space and improving overall building safety.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
