Description

Technical Field

[0001] This utility model relates to the field of water-stopping joint technology, and in particular to a water-stopping joint device for preventing leakage in flues. Background Technology

[0002] During the construction of building roofs, flue openings are usually reserved because kitchens and bathrooms typically need to use flues to vent fumes and other pollutants to the outside to ensure fresh and hygienic indoor air. These flues extend from the interior to the roof, where flue openings are reserved to connect the flues to the outside and achieve the functions of smoke and air exhaust.

[0003] In existing technologies, during the construction of buildings, pre-reserved openings are typically sealed using flue waterstops. Their main function is to prevent rainwater, snowmelt, and other external moisture from seeping into the interior through the gaps between the flue and the roof. Current sealing methods mostly involve wrapping waterproof sealing tape around the opening at the top of the waterstop. While this provides a significant seal between the waterstop and the flue / floor slab, the construction process is lengthy, and the tape, constantly exposed to air, is prone to shortening its lifespan due to varying weather conditions. Therefore, during renovations, construction workers need to regularly inspect the waterstops; otherwise, rainwater may seep into the building through the waterstop, requiring frequent replacement of the tape. Thus, using tape to seal waterstops increases the workload for construction workers and increases the risk of rainwater seepage into the building if inspections are not timely. Summary of the Invention

[0004] This utility model provides a leak-proof flue water-stop device to solve the problems in the background art.

[0005] This utility model embodiment adopts the following technical solution: a leak-proof flue water-stop device, including a flue water-stop, with an integrally formed connecting vertical pipe above the flue water-stop, replacing the open opening above the flue water-stop; a curved pipe is provided above the connecting vertical pipe, one end of the curved pipe is installed at the upper end of the connecting vertical pipe, and the other end of the curved pipe is located on one side of the connecting vertical pipe and faces downward; a sealing joint and a sealing cap for sealing the curved pipe are provided at the other end of the curved pipe, and the sealing cap is rotatably installed on the sealing joint, allowing the curved pipe to be in a closed state. This solves the problem in the prior art that using waterproof tape to seal the flue water-stop not only increases the burden on construction workers, but also easily leads to water leakage in the flue water-stop due to tape wear.

[0006] Furthermore, the sealing joint consists of a connecting plate and a threaded connecting post. The connecting plate is installed on the other end of the curved tube, and the threaded connecting post is installed on the connecting plate. Both the connecting plate and the threaded connecting post are hollow. The connecting plate and the threaded connecting post are used to seal the cap on the curved tube. The connecting plate and threaded connecting post are located on the other end of the curved tube primarily to facilitate the installation of the sealing cap on the curved tube.

[0007] Furthermore, a connecting strap is provided on one side of the connecting plate, and a connecting circular plate is provided on the connecting strap. The connecting circular plate is rotatably connected to the sealing cap. The function of the connecting strap and the connecting circular plate is to hold the sealing cap and prevent the sealing cap from being lost.

[0008] Furthermore, one end of the sealing cap has a threaded groove, and the other end of the sealing cap is connected to the connecting circular plate. The sealing cap is rotatably mounted on the threaded connecting post through the internal threaded groove, and when the sealing cap is mounted on the threaded connecting post, it contacts the connecting plate. The threaded connection of the sealing cap onto the connecting plate and the threaded connecting post makes it easier to assemble and disassemble.

[0009] Furthermore, a circular groove is provided on the other end of the sealing cover, through which the sealing cover is connected to the connecting circular plate. The circular groove on the sealing cover allows the connecting circular plate to be rotatably connected to the sealing cover.

[0010] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0011] In this application, the connecting vertical pipe and the curved pipe on the flue waterstop joint can change the original upward-facing opening of the flue waterstop joint to a downward-facing opening. This prevents rainwater from falling from top to bottom into the opening of the flue waterstop joint. The cooperation between the curved pipe and the connecting vertical pipe allows the flue waterstop joint to effectively prevent foreign objects, rainwater, or moisture from other factors from entering the flue waterstop joint while still providing ventilation. Furthermore, the sealing cap adds an extra layer of protection. The sealing cap can be closed when ventilation is not required, ensuring that the flue waterstop joint is not connected to the outside. This replaces the existing method of using waterproof tape to seal the flue waterstop joint. The sealing cap is durable and easy to operate. This method solves the problem that using waterproof tape to seal the flue waterstop joint in the existing technology not only increases the burden on construction workers but also easily leads to water leakage due to tape wear.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-4 This utility model provides a leak-proof flue water-stop device 1, including a flue water-stop 1. An integrally formed connecting vertical pipe 2 is provided above the flue water-stop 1, which replaces the open opening above the flue water-stop 1. A curved pipe 3 is provided above the connecting vertical pipe 2. One end of the curved pipe 3 is installed at the upper end of the connecting vertical pipe 2, and the other end of the curved pipe 3 is located on one side of the connecting vertical pipe 2 and faces downward. A sealing joint 4 and a sealing cap 5 for sealing the curved pipe 3 are provided at the other end of the curved pipe 3. The sealing cap 5 is rotatably installed on the sealing joint 4, and the sealing cap 5 can make the curved pipe 3 closed.

[0021] In this application, a structure is installed on the existing flue sealing section 1 to prevent rainwater from entering. The structure consists of a connecting vertical pipe 2, a curved pipe 3, and a sealing cap 5. The connecting vertical pipe 2 and the curved pipe 3 on the flue sealing section 1 change the original upward-facing opening of the flue sealing section 1 to a downward-facing opening. This has the advantage of preventing rainwater from falling from top to bottom into the opening of the flue sealing section 1. The cooperation between the curved pipe 3 and the connecting vertical pipe 2 allows the flue sealing section 1 to effectively prevent moisture from foreign objects, rainwater, or other factors from entering while still providing ventilation. In the flue water-stop section 1, the sealing cap 5 adds an extra layer of protection. The sealing cap 5 can seal the flue water-stop section 1 when ventilation is not required, thus ensuring that the flue water-stop section 1 is not connected to the outside. This replaces the existing technology of using waterproof tape to seal the flue water-stop section 1. The sealing cap 5 can be used for a long time and is easy to operate. This method solves the problem that the existing technology of using waterproof tape to seal the flue water-stop section 1 not only increases the burden on construction workers, but also easily leads to water leakage in the flue water-stop section 1 due to tape wear.

[0022] During building construction, various building materials and construction techniques are used, which may generate harmful gases such as formaldehyde and benzene, as well as dust. As one of the air passages within a building, if the flue sealing section 1 is closed, these harmful gases and dust will be difficult to expel and will accumulate indoors. This not only affects the health of construction workers but may also pose certain safety hazards, such as the risk of explosion if the concentration reaches a certain level and comes into contact with an open flame. Maintaining ventilation of the flue sealing section 1 allows these harmful gases and dust to be expelled outdoors in a timely manner, improving the indoor construction environment and ensuring the safety and health of construction workers. Therefore, in this application, the connection between the vertical pipe 2 and the curved pipe 3 is essential, allowing ventilation of the flue sealing section 1 while preventing rainwater or foreign objects from entering its interior.

[0023] Preferably, the sealing joint 4 is composed of a connecting plate 41 and a threaded connecting post 42. The connecting plate 41 is installed on the other end of the curved tube 3, and the threaded connecting post 42 is installed on the connecting plate 41. The interior of both the connecting plate 41 and the threaded connecting post 42 is hollow. The connecting plate 41 and the threaded connecting post 42 are used to seal the cover 5 installed on the curved tube 3.

[0024] In this application, the connecting plate 41 and threaded connecting post 42 are provided on the other end of the curved tube 3 mainly to make it easier for the sealing cover 5 to seal the curved tube 3. The purpose of the hollow interior of the connecting plate 41 and threaded connecting post 42 is to prevent blockage of the curved tube 3. In this way, the connecting plate 41 and threaded connecting post 42 on the curved tube 3 will not affect the normal flow of the curved tube 3 with the outside air.

[0025] Preferably, a connecting strip 43 is provided on one side of the connecting plate 41, and a connecting circular plate 44 is provided on the connecting strip 43, and the connecting circular plate 44 is rotatably connected to the sealing cover 5.

[0026] In this application, the connecting strap 43 and the connecting circular plate 44 are used to place the sealing cover 5. This arrangement allows the sealing cover 5 to be suspended on one side of the curved tube 3 by the connecting strap 43 and the connecting circular plate 44 even when it is not installed on the curved tube 3, thus preventing the sealing cover 5 from being lost.

[0027] Preferably, one end of the sealing cover 5 has a threaded groove inside, and the other end of the sealing cover 5 is connected to the connecting circular plate 44. The sealing cover 5 is rotatably mounted on the threaded connecting post 42 through the internal threaded groove, and the sealing cover 5 contacts the connecting plate 41 when mounted on the threaded connecting post 42.

[0028] In this application, the sealing cover 5 is installed on the connecting plate 41 and the threaded connecting post 42 by means of threaded connection, which makes it more convenient to install and remove. Since the sealing cover 5 is installed on the threaded connecting post 42 with the opening facing upward, if rainwater remains inside the sealing cover 5 for a long time, it will easily affect its service life. Therefore, the sealing cover 5 is installed on the threaded connecting post 42 and is in close contact with the connecting plate 41, which can prevent rainwater from falling into the sealing cover 5.

[0029] Preferably, a circular groove 51 is provided on the other end of the sealing cover 5, and the sealing cover 5 is connected to the connecting circular plate 44 through the circular groove 51.

[0030] The circular groove 51 on the sealing cover 5 allows the connecting circular plate 44 to be rotatably connected to the sealing cover 5, so that the connecting strip 43 will not be twisted when the sealing cover 5 is rotated and installed on the threaded connecting post 42.

[0031] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
