Description

Technical Field

[0001] The utility model relates to the technical field of fire-resistant air ducts, in particular to a double-sided elliptical steel fire-resistant air duct with aluminum silicate sandwiched in the middle. Background Art

[0002] Ventilation duct systems, an essential component of ventilation and air conditioning systems for industrial and residential buildings, effectively transport and distribute air, controlling the concentration of harmful gases in the environment and ensuring air quality. They are a key element of urban infrastructure. Traditionally, these ducts have adopted a square design, but this design lacks fire and high-temperature resistance and effective insulation. This drawback is particularly pronounced in the event of an internal fire, as the duct structure is easily damaged. Furthermore, their high space utilization further limits their flexibility in compact environments. Utility Model Content

[0003] The purpose of the present invention is to provide a double-sided elliptical steel refractory air duct with aluminum silicate sandwiched in the middle, so as to solve the problems raised in the above background technology.

The fixing plate has fixing screw holes, aluminum silicate sandwiched between the inner side of the steel outer shell, a steel inner shell sandwiched between the inner side of the aluminum silicate, and a connecting flange mounted on the left side of the steel inner shell.

[0005] Preferably, the connecting flange has the same overall structure as the main body.

[0006] Preferably, the inner side of the steel inner shell is a hollow structure.

[0007] Preferably, the flange is directly fixed on the air duct via the groove thereon.

[0008] Preferably, the height of the U-shaped tube bracket is greater than or equal to the side length of the air duct.

[0009] Preferably, a sealing rubber ring is installed between the two air ducts.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This double-sided, elliptical steel fire-resistant duct is primarily constructed of high-quality steel. Its innovative design incorporates high-performance aluminum silicate insulation between the inner and outer shells, significantly enhancing the duct's fire resistance. The unconventional elliptical cross-section design not only enhances the adaptability and flexibility of the structure, but also facilitates efficient space utilization in diverse application scenarios, particularly in space-constrained environments.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Example: See Figure 1 The present invention provides a technical solution: a double-sided elliptical steel fire-resistant air duct with aluminum silicate sandwiched between the two sides. The duct comprises a main body 1 having multiple screw holes 2 formed therein. A groove 9 is connected to the inner side of the main body 1. A steel outer shell 3 is connected to the left side of the main body 1. A U-shaped tube bracket 4 is mounted below the steel outer shell 3. A fixing plate 5 is connected to the upper side of the U-shaped tube bracket 4. The fixing plate 5 has fixing screw holes 6 formed therein. Aluminum silicate 11 is sandwiched between the inner side of the steel outer shell. A steel inner shell 10 is sandwiched between the inner side of the aluminum silicate 11. A connecting flange 7 is mounted on the left side of the steel inner shell 10.

[0017] The connecting flange 7 has the same overall structure as the main body 1 .

[0018] In this embodiment, the problem of installation failure due to direction issues is avoided.

[0019] The inner side of the steel inner shell 10 is a hollow structure.

[0020] In this embodiment, space is provided for air circulation.

[0021] The flange 7 is directly fixed on the air duct through the groove 9 thereon.

[0022] In this embodiment, the loss of materials is avoided and the workload of on-site installation workers is reduced.

[0023] The height of the U-shaped tube bracket 4 is greater than or equal to the side length of the air duct.

[0024] In this embodiment, it is ensured that the air duct can be accurately placed on the bracket during installation.

[0025] Among them, a sealing rubber ring is installed between the two air ducts.

[0026] In this embodiment, the friction between the two air ducts is effectively reduced, and the possibility of air leakage is also reduced.

[0027] How it works: After the materials arrive at the construction site, the first step is a thorough inspection to confirm that there is no damage during transportation. Next, the flanges of the two sections of duct are precisely aligned. Using the pre-set screw holes on the flanges, high-strength bolts are used to securely connect them, ensuring a seamless seal.

[0028] The bracket is then securely fixed to the desired location, typically the ceiling or structure, using the bracket fixing plate to provide a stable support base for the duct system. The connected duct section is precisely placed on the bracket, and subsequent duct sections are connected in sequence until the entire duct system is connected, forming a complete and stable delivery network.

[0029] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
