Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air ducts, and particularly relates to a modular composite fireproof air duct. Background Technique
[0002] In the field of building mechanical and electrical engineering, fireproof air ducts are mainly used in the basement smoke exhaust system or the exhaust and smoke exhaust combined system of the project, the air conditioning ventilation system, and the protection of air ducts passing through fire compartments. Especially for the conversion air ducts of the centralized supply and exhaust ducts of multiple systems, large-sized air ducts are generally designed due to the large air volume, and the processing and installation are very difficult. The existing fireproof air ducts are assembled by installing fireproof boards, and flange plates are generally used for connection and fixation at the joints, making the installation more difficult.
[0003] Therefore, a new type of fireproof air duct with the publication number of "CN217272668U" includes a first fireproof air duct. Convex platforms and chutes are respectively welded on both end faces of the first fireproof air duct. A connecting plate is welded on the top of the first fireproof air duct, and the connecting plate is connected to a suspender. A fixed circular plate is welded on the top of the suspender. A second fireproof air duct is installed inside the first fireproof air duct. A motor driving device is installed at the inner bottom of the second fireproof air duct. The motor driving device is hingedly connected to a fireproof partition, and a temperature sensor is installed on one side of the motor driving device. This device can quickly install the fireproof air duct without using flange plates, enhance the airtightness, and at the same time can detect whether the flame enters the fireproof air duct and raise the fireproof partition to block the spread of the flame.
[0004] However, for the above new type of fireproof air duct, although the two end faces of the first fireproof air duct can be processed into convex platforms and chutes respectively to achieve the quick installation of the fireproof air duct, and the connection between the fireproof air ducts can be made tighter and the airtightness can be stronger by bolt-connecting the sealing plates at the top joints of the first fireproof air duct, there are still the following obvious defects during use: The above-mentioned air duct cup body is formed by bending and welding a metal plate into a specific length. During the laying process of the air duct, due to the specific length of the air duct, it is impossible to disassemble and assemble the air duct to change its length according to the limited space of the air duct laying, so as to realize the laying of branch air ducts in the limited space. Summary of the Invention
[0005] The purpose of the utility model is to provide a modular composite fireproof air duct to solve the problems raised in the above background technique.
[0006] To achieve the above object, the utility model provides the following technical solution: A modular composite fireproof air duct, including a module main board, a module combined side board, and A combined profiles and B combined profiles for modular combined fixation between the module main board and the module combined side board. The upper end and the bottom side of the side of the A combined profile are integrally formed with module combined groove A for combining the module main board and the module combined side board. The B combined profile is of an I-shaped structure, and module combined groove B for modularly combining and extending the air duct of the module main board and the module combined side board is integrally formed on both sides of the B combined profile.
[0007] Preferably, both the module main board and the module combined side board include two stainless steel plates, and a fireproof layer is connected between the two stainless steel plates to achieve the fireproof effect of the air duct.
[0008] Preferably, rubber gaskets for sealing the combination of the module main board and the module combined side board by using the A combined profile and the B combined profile are provided on three surfaces of the inner walls of the module combined groove A and the module combined groove B, which can make the combination of the module main board and the module combined side board have better airtightness and be more firm.
[0009] Preferably, the combination of the module main board and the module combined side board of the air duct is extended and assembled and connected through the module combined groove B on the B combined profile of the I-shaped structure around the perimeter to achieve the quick combined assembly of the air duct.
[0010] Preferably, the four corners of the combination of the module main board and the module combined side board of the air duct are hermetically combined through the module combined groove A on the A combined profile, which can enable the disassembly and assembly combination of the air duct and facilitate the handling and transfer of the air duct.
[0011] Compared with the prior art, the technical effects and advantages of the utility model are as follows: For this modular composite fireproof air duct, the module main board and the module combined side board are combined and assembled by using the module combined groove A and the module combined groove B on the A combined profile and the B combined profile. Moreover, the module main board and the module combined side board are finished products produced by pre-processing. The module combined groove A on the A combined profile is used to assemble and combine the four right-angle corners of the air duct with appropriate size and diameter formed by the module main board and the module combined side board. And for the extension of the length of the air duct, the module combined groove B in the B combined profile is used to assemble and connect one end of the combined air duct with the module main board and the module combined side board. Thus, air ducts of various lengths can be combined, and different lengths of air ducts can be assembled by using the above combined structural parts according to the different laying spaces of the air duct. At the same time, the modular assembly and laying of the air duct are realized, which can speed up the progress of the air duct laying. Furthermore, the modular air duct can be disassembled and assembled arbitrarily to change its length to achieve laying in a limited space. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: a modular composite fireproof air duct, including a module main board 1 and a module combined side board 2, as well as A combined profiles 3 and B combined profiles 4 that are modularly combined and fixed between the module main board 1 and the module combined side board 2. The air duct can utilize its modular assembly connection to accelerate the laying of the air duct. The upper end and the bottom side of the side of the A combined profile 3 are integrally formed with module combined grooves A 5 for combining the module main board 1 and the module combined side board 2, so that the module main board 1 and the module combined side board 2 can be combined into a rectangular and square air duct. Moreover, the module main board 1 and the module combined side board 2 are pre-processed finished products, which is convenient for the assembly connection of the air duct, making the laying connection of the air duct simpler and more convenient. The B combined profile 4 is of an I-shaped structure, which is conducive to the module main board 1 and the module combined side board 2 to extend and assemble the length of the air duct. And the two sides of the B combined profile 4 are integrally formed with module combined grooves B 6 for modularly combining and extending the air duct of the module main board 1 and the module combined side board 2, which can assemble and connect the module main board 1 and the module combined side board 2 to facilitate the extension and shortening of the air duct.
[0019] The module main board 1 and the module combined side plate 2 both include two stainless steel plates 7, making the air duct more durable after assembly. A fireproof layer 8 is connected between the two stainless steel plates 7 to prevent damage to the air duct caused by a fire. Rubber gaskets 9 for sealing the module main board 1 and the module combined side plate 2 using the A combined profile 3 and the B combined profile 4 are provided on three surfaces of the inner walls of the module combined groove A5 and the module combined groove B6. After the module main board 1 and the module combined side plate 2 are assembled with the A combined profile 3 and the B combined profile 4, the connection part maintains a certain tightness, avoiding leakage of harmful gases transported inside and improving the safety of the modular air duct.
[0020] The module main board 1 and the module combined side plate 2 of the air duct are assembled and connected by extending through the module combined groove B6 on the B combined profile 4 with an I-shaped structure around the combination, realizing the extension and shortening of different lengths of the modular branch pipes, making the modular air duct more simple and easy to operate. The four corners of the combination of the module main board 1 and the module combined side plate 2 of the air duct are hermetically combined through the module combined groove A5 on the A combined profile 3, ensuring that each connection part maintains a certain tightness after the modular air duct is assembled and avoiding air leakage.
[0021] Specifically, during use, both ends of the two module main boards 1 are assembled and combined with one of the module combined grooves A5 on the A combined profile 3. Subsequently, the two pre-prepared module combined side plates 2 are inserted into the other module combined groove A5 on the A combined profile 3, thus assembling and combining into a rectangular air duct. And the module combined groove B6 on one side of the I-shaped B combined profile 4 is used to assemble one end of the module main board 1 and the module combined side plate 2 on the four surfaces of the air duct that need to be extended. Then, the module main board 1 and the module combined side plate 2 that need to be assembled and extended are inserted into the module combined groove B6 on the other side of the B combined profile 4. And the extended air duct is combined and fixed at the four 90-degree right angles by using the module combined groove A5 in the A combined profile 3, thus realizing the extension of the modular assembly and combination of the air duct, and being able to perform arbitrary combination of branch pipes with different lengths according to the installation space, further improving the convenience of modular air duct installation.
[0022] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
