Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a hanging hole-free installation device for an exhaust duct. Background Art

[0002] Conventional exhaust duct installation projects reserve openings in the cast-in-place slab. These openings are typically larger than the duct's cross-sectional dimensions. Later, after the duct is installed, the holes are then hoisted and plastered to repair the gaps in the reserved openings. This complex process creates a significant risk of leakage. Furthermore, hoisting holes after the duct is installed significantly impacts the waterproofing of water-filled rooms like the kitchen. Improperly installed unloading rebar can easily cause the duct to deform and crack. Failure to ensure the quality of the hoisting holes can also lead to leakage.

[0003] Therefore, it is still of great significance to find a new technology that can solve the drawbacks of traditional exhaust duct installation methods, filter out the complicated processes of traditional construction, and improve construction quality. Utility Model Content

[0006] The beneficial effects are: the utility model has a simple structure, does not require wooden molds and fine stone concrete, only a small amount of polymer mortar, saving transportation and material costs, the main body construction is convenient and efficient, saving carpentry costs, the later exhaust duct installation does not require hanging holes, the construction quality is high and efficient, and the construction period cost is saved.

[0007] A further technical solution of the present invention is that the gap is filled and sealed with polymer mortar containing an expansion agent and a waterproofing agent.

[0008] A further technical solution of the present invention is that the connecting member includes an embedded member, and an upper blocking frame and a lower blocking frame are fixedly mounted on the upper and lower sides of the embedded member respectively.

[0009] A further technical solution of the present invention is that the length of the lower blocking frame is greater than that of the upper blocking frame.

[0010] The beneficial effect is that the top end of the exhaust duct is installed inside the lower blocking frame, so that the longer lower blocking frame can reinforce the exhaust duct.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments. In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise expressly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific circumstances.

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-Figure 3 As shown, an exhaust duct installation device without hanging holes includes multiple connectors 2, each connector 2 is buried in the inside of the floor slab 1 of one floor, an exhaust duct 3 is installed between two adjacent connectors 2, the exhaust duct 3 is plugged into the inside of the connector 2, and a gap is left between the connector 2 and the exhaust duct 3, the gap is filled and sealed with polymer mortar containing expansion agent and waterproofing agent, a plurality of positioning members 4 for positioning the exhaust duct 3 are fixedly installed inside the connector 2, the positioning members 4 enable the exhaust duct 3 to be installed at the center of the connector 2, there are multiple positioning members 4, multiple positioning members 4 are evenly distributed, the positioning member 4 is L-shaped, and can be made by bending discarded steel bar heads in the actual production process.

[0020] like Figure 2 As shown, the connecting part 2 includes an embedded part 21, and an upper blocking frame 22 and a lower blocking frame 23 are fixedly installed on the upper and lower sides of the embedded part 21 respectively. The length of the lower blocking frame 23 is greater than the length of the upper blocking frame 22. The top of the exhaust duct 3 is installed inside the lower blocking frame 23. Therefore, the lower blocking frame 23 will be affected by gravity to a certain extent. Therefore, the longer lower blocking frame 23 can reinforce the exhaust duct 3. The upper blocking frame 22 and the lower blocking frame 23 are both made of flat iron. Since the flat iron is thin, the upper blocking frame 22 and the lower blocking frame 23 are both welded by carbon dioxide gas shielded welding, and can be less than fully welded, with a 30% weld seam.

[0021] During use, during the main construction process, the connecting part 2 is first embedded in the interior of the floor 1, and the exhaust duct 3 is later installed inside the connecting part 2. Due to the positioning of the positioning part 4, the exhaust duct 3 can be located in the middle of the connecting part 2, and a gap is left between the exhaust duct 3 and the embedded part 21 of the connecting part 2. Finally, the gap is filled and sealed with polymer sand containing an expansion agent and a waterproofing agent.

[0022] The utility model has a simple structure, does not require wooden formwork and fine stone concrete, and only requires a small amount of polymer mortar, which saves transportation and material costs. The main body construction is convenient and efficient to pre-buried, saving carpentry costs. The later exhaust duct installation does not require hanging holes, with high construction efficiency and saving construction period costs.
