[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 and Figure 2 As shown, a smoke-proof rectangular exhaust duct includes two exhaust pipes 1, with a connecting component 3 inserted into the opposite sides of the two exhaust pipes 1. The inner walls of the two exhaust pipes 1 are coated with a protective coating 2, and a reinforcing component 4 is embedded inside the two exhaust pipes 1. The exhaust pipes 1 are rectangular in shape, and the front of the exhaust pipes 1 is chamfered.

[0025] The exhaust pipe 1 is designed with a rectangle and chamfers to improve the overall structural strength of the exhaust pipe 1 and to ensure a better fit between the front of the exhaust pipe 1 and the installation position. The protective coating 2 is used to protect the interior of the exhaust pipe 1 and prevent smoke leakage, which would affect the performance.

[0026] By using a chamfered design, the connection between the exhaust duct and the wall can be reinforced with crack-resistant mortar during construction, effectively preventing smoke leakage, reducing the plastering process on the tiled surface in front of the exhaust duct, reducing material usage, and thus reducing construction costs.

[0027] This leak-proof rectangular flue optimizes the existing L-shaped flue structure, which suffers from structural defects, cracking defects that are unavoidable when in contact with the wall during installation, and reduces the defects caused by insufficient vertical load after multiple layers of L-shaped flue are installed, which leads to deformation and displacement of the flue.

[0028] like Figure 1 and Figure 3 As shown, the connecting component 3 includes a connecting groove plate 31, and mounting grooves 32 are provided at both the upper and lower ends of the connecting groove plate 31. The inner wall of the mounting groove 32 is inserted into the end of the exhaust pipe 1.

[0029] By using the connection groove plate 31 to insert into the end of the exhaust pipe 1, the connection between the two exhaust pipes 1 can be realized, thereby effectively reducing the occurrence of smoke leakage.

[0030] like Figure 3 As shown, side ears 34 are fixedly connected to the left and right positions of the front part of the connecting groove plate 31. The inner wall of the side ears 34 is fixedly fitted with mounting pads 33, which are in the shape of "I".

[0031] By utilizing the side lugs 34 and mounting pads 33, the exhaust pipe 1 can be installed on the wall, improving the overall structural stability of the exhaust pipe 1 after construction and preventing tilting or skewing. At the same time, it can effectively reduce the problem of cracking after plastering.

[0032] like Figure 2 and Figure 4As shown, the reinforcing component 4 includes several vertical reinforcing ribs 41 and several linearly distributed ring ribs 42. The vertical reinforcing ribs 41 and the ring ribs 42 are both embedded inside the exhaust pipe 1, and the vertical reinforcing ribs 41 and the ring ribs 42 are arranged vertically.

[0033] Vertical stiffeners 41 and ring stiffeners 42 are used to strengthen the overall structure of the exhaust pipe 1, improve the stability of the overall structure, and solve the problems of unloading and tensile cracking.

[0034] like Figure 4 and Figure 5 As shown, the vertical reinforcing rib 41 is fixedly connected by several linearly distributed sleeves 43. The outer wall of the sleeve 43 is snapped with a first buckle 44, and the outer wall of the ring rib 42 is inserted with a second buckle 47. The inside of the second buckle 47 is provided with an annular cavity 48.

[0035] The vertical reinforcing bars 41 and 42 are connected to form a steel cage similar to the structure of the exhaust pipe 1 by using the function of clip 44 and clip 47. The material of the vertical reinforcing bars 41 and 42 is steel wire.

[0036] like Figure 4 and Figure 5 As shown, a reinforcing plate 46 is fixedly connected to the bottom of buckle 2 47. One side of the reinforcing plate 46 is fixedly connected to the outer wall of buckle 1 44. A support block 45 is fixedly connected to the side of the outer wall of buckle 1 44 near the rib 42. The inner wall of the support block 45 overlaps with the outer wall of the rib 42.

[0037] The reinforcing plate 46 is used to connect the first clip 44 and the second clip 47. A support block 45 is provided on the outer wall of the first clip 44 to improve the stability of the connection between the vertical reinforcing bar 41 and the ring bar 42 and to improve the strength of the steel cage.

[0038] The working principle of this utility model is as follows: When producing the flue, the first buckle 44 is snapped onto the sleeve 43 on the outer wall of the vertical reinforcing rib 41, and the ring rib 42 is snapped onto the inner wall of the second buckle 47 to connect the vertical reinforcing rib 41 and the ring rib 42, forming a steel cage. The steel cage is then placed in a mold, and concrete is poured into the mold to form the exhaust pipe 1. A protective coating 2 is then sprayed onto the inner wall of the exhaust pipe 1, and the flue can then be processed. When constructing the flue, the flue is placed in an appropriate position, and the connecting component 3 is inserted into the connection between the exhaust pipe 1 and the exhaust pipe 1. Expansion screws are then inserted into the inner cavity of the mounting pad 33 to fix the exhaust pipe 1 to the wall. Then, plastering can be carried out on the outside of the flue.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
