DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figure 1 and Figure 2 As shown, a smoke leakage-proof rectangular exhaust duct includes two exhaust pipes 1, the opposite surfaces of the two exhaust pipes 1 are commonly plugged with a connecting component 3, the inner walls of the two exhaust pipes 1 are sprayed with a protective coating 2, and the interiors of the two exhaust pipes 1 are embedded with a reinforcing component 4. The exhaust pipe 1 is rectangular in shape, and the front part of the exhaust pipe 1 is provided with a chamfer.

[0025] The exhaust duct 1 is rectangular and chamfered to improve the strength of the overall structure of the exhaust duct 1 so that the front of the exhaust duct 1 fits better with the installation position; the protective coating 2 is used to protect the interior of the exhaust duct 1 to avoid smoke leakage in the exhaust duct 1 itself, thereby affecting the use effect.

[0026] By adopting the chamfer setting, the joint between the exhaust duct and the wall can be densified with anti-cracking mortar during construction, which effectively prevents smoke leakage, reduces the plastering process of the tile surface in front of the exhaust duct, reduces the use of materials, and thus reduces the construction cost;

[0027] The smoke-leakage-proof rectangular smoke exhaust duct optimizes the existing L-shaped smoke duct structure difference, the unavoidable crack resistance defects in the contact surface with the wall during installation, and reduces the defect of deformation and displacement of the smoke exhaust duct caused by insufficient vertical load after multiple layers of the L-shaped smoke duct are installed.

[0028] like Figure 1 and Figure 3 As shown, the connection assembly 3 includes a connection slot plate 31 , and mounting slots 32 are provided at both upper and lower ends of the connection slot plate 31 , and the inner wall of the mounting slot 32 is plugged into the end of the exhaust pipe 1 .

[0029] By utilizing the plugging effect of the connecting slot plate 31 and the end of the exhaust pipe 1, the connection between the two exhaust pipes 1 is achieved, thereby effectively reducing the phenomenon of smoke leakage.

[0030] like Figure 3 As shown, the left and right positions of the front part of the connecting slot plate 31 are fixedly connected with side ears 34, and the inner wall of the side ears 34 is fixedly sleeved with a mounting pad 33, and the shape of the mounting pad 33 is an "I" shape.

[0031] The side ears 34 and the mounting pads 33 are utilized to mount the exhaust duct 1 on the wall, thereby improving the stability of the overall structure of the exhaust duct 1 after construction, avoiding the phenomenon of tilting and tilting, and effectively reducing the problem of cracking after plastering.

[0032] like Figure 2 and Figure 4As shown, the reinforcing assembly 4 includes a plurality of vertical reinforcing ribs 41 and a plurality of linearly distributed ring ribs 42 . The vertical reinforcing ribs 41 and the ring ribs 42 are both embedded in the exhaust duct 1 , and the vertical reinforcing ribs 41 and the ring ribs 42 are vertically arranged.

[0033] The vertical reinforcing ribs 41 and the ring ribs 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 crack resistance.

[0034] like Figure 4 and Figure 5 As shown, the vertical reinforcing ribs 41 are fixedly connected with a plurality of linearly distributed pipe sleeves 43, the outer wall of the pipe sleeve 43 is clamped with a buckle 1 44, the outer wall of the ring rib 42 is plugged with a buckle 2 47, and an annulus 48 is opened inside the buckle 2 47.

[0035] The buckle 1 44 and the buckle 2 47 are used to connect the vertical reinforcement ribs 41 and the ring ribs 42 to form a steel cage similar to the exhaust duct 1; the materials of the vertical reinforcement ribs 41 and the ring ribs 42 are steel wires.

[0036] like Figure 4 and Figure 5 As shown, a reinforcing plate 46 is fixedly connected to the bottom of the second clip 47, one side of the reinforcing plate 46 is fixedly connected to the outer wall of the first clip 44, and a support block 45 is fixedly connected to the side of the outer wall of the first clip 44 close to the ring rib 42, and the inner wall of the support block 45 overlaps the outer wall of the ring rib 42.

[0037] The reinforcing plate 46 is used to connect the buckle 1 44 and the buckle 2 47, and a support block 45 is provided on the outer wall of the buckle 1 44 to improve the stability of the connection between the vertical reinforcing ribs 41 and the ring ribs 42 and improve the strength of the steel cage.

[0038] The working principle of the present invention is as follows: when producing the smoke exhaust duct, the buckle 1 44 is clamped to the position of the pipe sleeve 43 on the outer wall of the vertical reinforcement rib 41, and then the ring rib 42 is clamped to the inner wall of the buckle 2 47 to achieve the connection between the vertical reinforcement rib 41 and the ring rib 42 to form a steel cage, and then the steel cage is placed in a mold, and then concrete is injected into the mold to form an exhaust duct 1, and then a protective coating 2 is sprayed on the inner wall of the exhaust duct 1 to process the smoke exhaust duct; when constructing the smoke exhaust duct, the smoke exhaust duct is placed in an appropriate position, and then the connecting component 3 is inserted into the connection between the exhaust duct 1 and the exhaust duct 1, and the expansion screw is inserted into the inner cavity of the mounting pad 33 to fix the exhaust duct 1 on the wall, and then the outer side of the smoke exhaust duct can be coated with plaster.
