Abstract
Description
Technical Field
[0001] This application relates to the technical field of building anti-seepage, and in particular to an anti-seepage structure for the floor of a kitchen flue. Background Art
[0002] A flue is a tubular device for exhausting waste gas and smoke, also known as an exhaust duct, ventilation duct, or residential exhaust duct. A residential flue refers to a vertical pipe component for exhausting flue gas or waste gas. During the construction of the main structure, holes for the ventilation flue are reserved according to the positions in the design drawings. The size of the holes is 50 - 80 mm larger than the outer dimension of the pipe component. Therefore, after the flue is installed, secondary concrete plugging needs to be carried out around the floor slab.
[0003] Currently, the concrete used for plugging between the hole and the vertical pipe component will have a poor bonding effect at the junction with the floor concrete due to differences in concrete composition, water content, etc., resulting in leakage, and then causing flue gas to seep into the house, which has deficiencies. Utility Model Content
[0004] In order to improve the problem of poor sealing between the hole and the vertical pipe component, this application provides an anti-seepage structure for the floor of a kitchen flue.
[0005] The anti-seepage structure for the floor of a kitchen flue provided by this application adopts the following technical solutions:
[0006] An anti-seepage structure for the floor of a kitchen flue includes a building body. A flue opening is provided on the building body. A flue pipe is arranged in the flue opening. An upper sealing plate and a lower supporting plate are precast at the flue opening of the building body. A partition plate is arranged on the flue pipe. The partition plate is located between the upper sealing plate and the lower supporting plate. Concrete is filled between the flue pipe and the flue opening of the building body. The upper sealing plate, the lower supporting plate, and the partition plate are all precast in the concrete.
[0007] By adopting the above technical solutions, when workers build the flue opening of the building body, they first embed the lower supporting plate and the upper sealing plate at the flue opening. A part of the lower supporting plate and the upper sealing plate will extend out of the inner wall of the flue opening. When the workers install the flue pipe at the flue opening of the building body, they straighten and level the flue pipe, then install the partition plate on the flue pipe to make the partition plate located between the upper sealing plate and the lower supporting plate, and finally pour concrete, so that the junction between the concrete of the building body and the later-poured concrete is placed in the later-poured concrete, thereby achieving the anti-seepage effect.
[0008] Optionally, a refractory coating is provided on the inner side wall of the flue pipe.
[0009] By adopting the above technical solution, the influence of the flue gas temperature on the flue duct is reduced, and the flue duct is greatly heated, which is beneficial to reducing the possibility that the flue duct is heated and separated from the concrete at the joint.
[0010] Optionally, a plurality of extension plates are rotatably arranged on the upper enclosing plate, and the plurality of extension plates are evenly distributed circumferentially along the axis of the flue duct. The cross section of the extension plate is L-shaped, and the extension plate is used to buckle above the partition enclosing plate.
[0011] By adopting the above technical solution, after the worker installs the partition enclosing plate on the flue duct, the worker rotates a plurality of extension plates in sequence, and the plurality of extension plates jointly buckle the partition enclosing plate, so that the cast concrete forms a complex concrete circuit in the cavity formed between the upper enclosing plate, the partition enclosing plate and the lower supporting enclosing plate, thereby reducing the possibility of anti-seepage of the concrete between the flue opening and the flue duct.
[0012] Optionally, vertical anti-seepage plates are arranged on the extension plates, and waterproof strips are arranged between adjacent two anti-seepage plates and between adjacent two extension plates.
[0013] By adopting the above technical solution, it is beneficial to block the liquid seeping into the extension plate from continuing to seep into the lower supporting enclosing plate, and further improves the anti-seepage effect of the concrete.
[0014] Optionally, rib plates are arranged on the partition enclosing plate, and structural plates are arranged on the lower supporting enclosing plate, and the structural plates are located between the rib plates and the flue duct.
[0015] By adopting the above technical solution, the complexity of the casting of the concrete between the partition enclosing plate and the lower supporting enclosing plate is further increased, which is beneficial to improving the anti-seepage effect of the concrete.
[0016] Optionally, a sealing ring groove is formed at the joint between the concrete and the flue duct, asphalt is filled in the sealing ring groove, and a dust-proof enclosing plate is arranged on the flue duct, and the dust-proof enclosing plate covers the top of the sealing ring groove.
[0017] By adopting the above technical solution, when the flue duct is separated from the concrete due to heat, the asphalt is heated and melted to fill the gap between the flue duct and the concrete, thereby reducing the possibility of liquid seeping into the gap between the flue duct and the concrete.
[0018] Optionally, a waterproof layer is jointly arranged outside the dust-proof enclosing plate and the concrete.
[0019] By adopting the above technical solution, it is beneficial to reduce the possibility of external liquid seeping onto the concrete.
[0020] Optionally, the partition baffle includes a first baffle and a second baffle. A fastening bolt is detachably provided on the first baffle. A fastening nut is threadedly connected to the fastening bolt. The fastening bolt slidably passes through the second baffle. The fastening nut is used to press the second baffle against the first baffle. A sealing ring is provided between the first baffle and the second baffle.
[0021] By adopting the above technical solution, workers install the first baffle and the second baffle on two flue pipes respectively, then fix the two stacked flue pipes through the fastening bolt and the fastening nut, and then seal the interface between the two flue pipes through the sealing ring, which is beneficial to reducing the infiltration of flue gas in the flue pipe.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. When workers build the flue opening of the building body, they first embed the lower supporting baffle and the upper sealing baffle at the flue opening. A part of the lower supporting baffle and the upper sealing baffle extends out of the inner wall of the flue opening. When workers install the flue pipe at the flue opening of the building body, they straighten and level the flue pipe, then install the partition baffle on the flue pipe, so that the partition baffle is located between the upper sealing baffle and the lower supporting baffle, and finally pour concrete, so that the joint between the concrete of the building body and the later-poured concrete is placed in the later-poured concrete, thereby achieving the anti-seepage effect;
[0024] 2. After workers install the partition baffle on the flue pipe, workers sequentially rotate a plurality of extension plates, and the plurality of extension plates jointly fasten the partition baffle, so that the poured concrete forms a complex concrete circuit in the cavity formed between the upper sealing baffle, the partition baffle and the lower supporting baffle, thereby reducing the possibility of anti-seepage of the concrete between the flue opening and the flue pipe;
[0025] 3. Workers install the first baffle and the second baffle on two flue pipes respectively, then fix the two stacked flue pipes through the fastening bolt and the fastening nut, and then seal the interface between the two flue pipes through the sealing ring, which is beneficial to reducing the infiltration of flue gas in the flue pipe.
