Description

Technical Field

[0001] This utility model relates to the field of fireproof air duct technology, specifically a fireproof air duct wrapped with calcium silicate composite board. Background Technology

[0002] Fire-resistant ducts need to meet specific fire resistance requirements to ensure they can maintain operation for a certain period during a fire and prevent the spread of fire. Their facing material must be non-combustible, such as calcium silicate composite board. Currently, fire-resistant ducts typically have the facing material directly fixed to the duct body using bolts or other connectors. In some cases, smoke and flames from a fire may enter the duct. However, the duct material is generally thin galvanized steel sheet, which is prone to thermal deformation at high temperatures. This can cause the sheet material to pull on the connectors due to its own weight, resulting in the connectors being pulled off the deformed duct and the sheet material falling off. This affects the duration the fire-resistant duct can maintain operation during a fire, causing considerable inconvenience. Utility Model Content

[0003] The purpose of this invention is to provide a fireproof air duct with calcium silicate composite board to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A fireproof air duct with calcium silicate composite board coating includes:

[0006] The tube consists of a pipe body, two plates, and two side plates. Both ends of the outer wall of the pipe body are fixedly fitted with sleeve frames. Each of the two sleeve frames has multiple connecting holes on one side. The two plates are located at the top and bottom sides of the outer wall of the pipe body, respectively. Each of the two plates has screw holes on opposite sides. The two side plates are located at opposite sides of the outer wall of the pipe body, respectively. Each of the two side plates has multiple circular holes at both ends of an adjacent side. Each opposite side of any plate is in contact with an adjacent side of the two side plates.

[0007] Furthermore, grooves are provided at both ends of adjacent sides of the two side plates, cutting grooves are provided on opposite sides of the two plates, a sealing rod is provided inside any cutting groove, multiple through holes are provided on one side of any sealing rod, and any sealing rod is movably embedded into the adjacent groove.

[0008] Furthermore, grooves are provided at both ends of the two plates and at both ends of the two side plates. Two abutment frames are movably sleeved at both ends of the outer wall of the tube, and embedded plates are fixedly connected to the four sides of the inner side wall of the two abutment frames. Any embedded plate is fixedly snapped into the interior of the adjacent groove.

[0009] Furthermore, the length and width of the inner sidewall of any of the support frames are greater than the length and width of the outer sidewall of the tube.

[0010] Furthermore, a heat insulation frame is provided between any abutment frame and the adjacent sleeve frame, and the interior of both heat insulation frames is movably sleeved with the outer wall of the pipe body.

[0011] Furthermore, both of the aforementioned plates, two side plates, four sealing rods, and two heat insulation frames are all made of calcium silicate composite board.

[0012] Furthermore, both the embedded panel and the two abutment frames are made of steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By directly covering the outer wall of the pipe with two plates and two side plates, and using expansion bolts to screw into the expansion portions of adjacent screw holes through adjacent circular holes and through holes, the two plates and two side plates form a frame-like structure to cover the pipe. The plates and side plates are not connected to the pipe itself, reducing the possibility of the covering material falling off due to pipe damage. When installing the duct, connection holes can be made on the insulation frame and the abutment frame, and bolts can be used to connect the insulation frame, abutment frame, and sleeve frame on two adjacent pipes together. When the pipe is deformed by heat, the side plates, plates, insulation frame, and abutment frame on two adjacent pipes can still maintain stability for a certain period of time thanks to the connectors, thereby improving the performance of the fireproof duct.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 In this embodiment of the utility model, a fireproof air duct with calcium silicate composite board includes:

[0022] The tube body 100 consists of two plates 200 and two side plates 300. Both ends of the outer wall of the tube body 100 are fixedly fitted with sleeve frames 110. Each of the two sleeve frames 110 has multiple connecting holes on one side. The two plates 200 are located at the top and bottom sides of the outer wall of the tube body 100, respectively. Each of the two plates 200 has screw holes on opposite sides. The two side plates 300 are located at opposite sides of the outer wall of the tube body 100, respectively. Each of the two side plates 300 has multiple circular holes at both ends of the adjacent side. Each of the two plates 200 is in contact with the adjacent side of the two side plates 300 on opposite sides.

[0023] Specifically, the two sleeve frames 110 can be directly welded to both ends of the pipe body 100, forming a basic air duct with the pipe body 100 and the two sleeve frames 110. Then, the two plates 200 can be attached to the top and bottom sides of the outer wall of the pipe body 100, and the two side plates 300 can be attached to the opposite sides of the outer wall of the pipe body 100, so that the two plates 200 and the two side plates 300 cover the pipe body 100 and form a frame-like body. Then, expansion screws can be used to insert the expanded part of the expansion screw into the screw hole on the plate 200, and then the expansion screw is screwed into the aligned screw hole through the circular hole on the side plate 300, so that the two plates 200 and the two side plates 300 are fixed to each other by the expansion screws. There is no direct connection between the two plates 200 and the two side plates 300 and the pipe body 100, thereby reducing the possibility of the outer covering material falling off when the pipe body 100 is damaged. Example

[0024] like Figures 2-4 As shown, in this embodiment, grooves 301 are provided at both ends of the adjacent side of the two side plates 300, and cutting grooves 201 are provided on both sides of the two plates 200. A sealing rod 400 is provided inside any cutting groove 201, and multiple through holes are provided on one side of any sealing rod 400. Any sealing rod 400 is movably embedded inside the adjacent groove 301.

[0025] In this embodiment, when the two plates 200 and the two side plates 300 are assembled into a frame, the cutting grooves 201 on the two plates 200 and the grooves 301 on the adjacent side plates 300 are connected. The sealing rod 400 can be inserted into the connected grooves 301 and cutting grooves 201. Then, expansion screws are used to fix the side plates 300 and the plates 200. The screws can pass through the through holes on the sealing rod 400 so that when the screws fix the position of the side plates 300 and the plates 200, they also fix the position of the sealing rod 400. This allows the sealing rod 400 to seal the gap at the connection and contact point between the plates 200 and the side plates 300.

[0026] like Figure 1 and Figure 3 As shown, in this embodiment, grooves 501 are provided at both ends of the two plates 200 and both ends of the two side plates 300. Two abutment frames 500 are movably sleeved at both ends of the outer wall of the tube 100, and embedded plates 510 are fixedly connected to the four sides of the inner side wall of the two abutment frames 500. Each embedded plate 510 is fixedly snapped into the interior of the adjacent groove 501. The length and width of the inner side wall of each abutment frame 500 are greater than the length and width of the outer side wall of the tube 100. A heat insulation frame 520 is provided between each abutment frame 500 and the adjacent sleeve frame 110. The interior of the two heat insulation frames 520 is movably sleeved with the outer side wall of the tube 100. The two plates 200, the two side plates 300, the four sealing rods 400, and the two heat insulation frames 520 are all calcium silicate composite boards.

[0027] In specific implementation, the two plates 200, two side plates 300, four sealing rods 400, and two heat insulation frames 520 are all manufactured from calcium silicate composite boards through cutting, drilling, and other processing. Calcium silicate composite boards are existing technology and will not be described in detail here. The two abutment frames 500 do not contact the pipe body 100, avoiding the influence of the pipe body 100 temperature on the abutment frames 500. Furthermore, the two heat insulation frames 520 prevent the temperature of the two sleeve frames 110 from easily affecting the abutment frames 500 and the embedded plates 510. The embedded plates 510 on the two abutment frames 500 can naturally fit into the grooves 501 on the two plates 200 and two side plates 300, thus fixing the two abutment frames 500 to the two... At both ends of the frame-like body composed of the plate 200 and the two side plates 300, when multiple tubes 100 are spliced ​​together with bolts, connection holes can be drilled on the heat insulation frame 520 and the abutment frame 500, so that the drilled connection holes are aligned with the bolt holes on the sleeve frame 110. Then, the bolts are passed through the abutment frame 500, the heat insulation frame 520 and the sleeve frame 110 on the two adjacent tubes 100 and screwed with nuts. Thus, when the tube 100 is deformed by heat, the two abutment frames 500, the heat insulation frame 520, the two plates 200 and the two side plates 300 on any one of the two adjacent tubes 100 can still maintain a certain stable state through bolts, expansion bolts and other connecting parts. Example

[0028] Based on Example 1, the heat resistance is improved by using steel to manufacture the embedded plate 510 and the abutment frame 500.

[0029] like Figure 1 and Figure 3 As shown, in this embodiment, both the embedded plate 510 and the two abutment frames 500 are made of steel.

[0030] In practice, both the embedded plate 510 and the abutment frame 500 are made of alloy steel, which has a strong high-temperature resistance. Furthermore, the abutment frame 500 and the embedded plate 510 are relatively thick, which can maintain stability for a certain period of time under high temperatures.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
