Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterproof maintenance of building exterior walls, in particular to a waterproof maintenance device for building exterior walls. Background Art
[0002] Because there are no mandatory specifications for wall holes for exhaust pipes of residential gas water heaters, there is often a lack of sufficient attention during the residential construction process, resulting in some buildings having no holes for exhaust pipes for gas water heaters at all. When installing gas water heaters, holes need to be drilled on site, which will inevitably damage the waterproof layer and insulation layer of the exterior wall; improper drilling and failure to adopt a reverse slope with high inside and low outside will cause rainwater to flow in, resulting in leakage of the exterior wall; or even if there are reservations, due to the lack of unified standards and specifications, problems such as unreasonable size and unreasonable location will occur, which can easily lead to leakage at the exhaust pipe holes and damage the walls and ceilings. Utility Model Content

[0020] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.
[0021] like Figure 1-5 As shown, a waterproof maintenance device for building exterior walls is characterized by comprising a cylindrical pipe (3) with a first internal thread (302) and a wing ring (301) arranged on a wall (1), an interior wall gland (4) with a first silicone gasket (402) and an external thread (401), and an exterior wall gland (5) with a second silicone gasket (503) and external threads on the gland outer wall (501) and the exterior wall gland retaining ring (502). It also comprises a protective cover (6) with a filter screen (603) at one end and a second internal thread (601) and a silicone sealing ring (602) at the other end. First, the protective cover (6) is padded with a silicone seal ring (602) and the outer wall gland (5) is tightened, and then the outer wall gland (5) and the inner wall gland (4) are respectively covered with a second silicone gasket (503) and a first silicone gasket (402) and screwed into the cylindrical pipe (3). The first silicone gasket (402) between the inner wall gland (4) and the inner wall (101) and the second silicone gasket (503) between the outer wall gland (5) and the outer wall (102) are squeezed and deformed to seal the smoke exhaust pipe wall hole (2). A gap (7) with a width of about 5-15 mm is formed between the inner wall of the smoke exhaust pipe wall hole on the wall and the outer wall of the cylindrical pipe. After the device is assembled, a grouting hole (8) is drilled horizontally through the inner wall gland retaining ring (403) of the device, and the grouting hole (8) is connected to the grouting gap (7). The device can not only effectively prevent rainwater from directly flowing into the smoke exhaust pipe and causing leakage, but also can completely seal the wall hole of the smoke exhaust pipe, thereby preventing water leakage from damaging the wall and the ceiling.
[0022] In a preferred embodiment of the utility model, a wall hole (2) for a smoke exhaust pipe of a gas water heater is pre-punched on the wall (1).
[0023] In a preferred embodiment of the utility model, the inner wall pressure cover (4) and the outer wall pressure cover (5) are fixed by being rotatably connected via a thread, and the inner wall pressure cover (4) and the outer wall pressure cover (5) rotate toward each other in a direction close to the wall and can be stuck on the inner wall (101) and the outer wall (102).
[0024] In a preferred embodiment of the utility model, the inner wall gland (4) and the outer wall gland (5) are respectively provided with a first silicone gasket (402) and a second silicone gasket (503); the first silicone gasket (402) between the inner wall gland (4) and the inner wall (101) and the second silicone gasket (503) between the outer wall gland (5) and the outer wall (102) are squeezed and deformed to seal the smoke exhaust pipe wall hole (2).
[0025] In a preferred embodiment of the present invention, the protective cover (6) is shaped like a trumpet, with a high interior and a low exterior, which makes it easy to drain rainwater. A stainless steel filter (603) is installed inside the protective cover (6) to prevent foreign objects such as birds and insects from entering. The protective cover (6) and the outer wall gland (5) are fixed by screw thread rotation. A silicone seal ring (602) is provided between the protective cover (6) and the outer wall gland (5). The flue pipe (9) is interference-fitted with the silicone seal ring (602), which allows the flue pipe and the seal ring to fit tightly together to prevent water vapor from entering.
[0026] The sealing method of this product for air conditioning holes is as follows:
[0027] First, screw the inner gland, fitted with a silicone gasket, onto the main pipe by screwing it inward. Then, pass the pipe from indoors through the wall hole of the smoke exhaust pipe. Next, place a silicone sealing ring on the threads of the rain shield and tighten it onto the outer gland by screwing it in. Finally, place a silicone gasket on the side of the outer gland closest to the exterior wall and screw it into the main pipe by screwing it in. Tighten the inner and outer glands on both sides of the pipe so that the retaining rings squeeze the silicone gasket and completely adhere to the inner and outer walls. Once this is complete, drill a hole in the retaining ring of the inner gland and inject a waterproof material such as glass glue or structural adhesive. Apply a layer of glass glue or structural adhesive to the inner and outer retaining rings.
[0028] The above structure itself has sufficient sealing and rainproof functions. Combined with the grouting process, the gaps in the wall holes and pipes of the smoke exhaust pipe are completely sealed to prevent rainwater from seeping into the room and damaging the walls and ceiling.
[0029] The above description is a detailed description of one embodiment of the present invention. The content described is only the best embodiment of the present invention, but the scope of protection of the present invention is not limited to this. Any changes or substitutions that are not conceived through creative work shall fall within the scope of patent protection of the present invention.
