Description

Technical Field

[0001] The present invention belongs to the technical field of water supply and drainage, and relates to a water supply and drainage integrated device, in particular to a four-way integrated drainer and an SI system with the four-way integrated drainer as the core. Background Art

[0002] The SI-system architecture effectively separates the supporting structural system (S) from the internal functional system (I) throughout the building's lifecycle, ensuring the structural system remains unchanged while enabling the diversity, expandability, and continuous renewal of the building's functions. Generally, the SI-system focuses on the variability of living spaces. However, bathrooms are relatively fixed in their projected position across different floors due to the need for lowered floors for same-floor drainage and the alignment of plumbing manifolds between upper and lower floors. The diversity, expandability, and continuous renewal of the SI-system are essentially centered around the water supply and drainage system, which is the most technically challenging.

[0003] Generally, a pipe shaft is installed in each bathroom, and when two bathrooms are adjacent, they share a pipe shaft. The existing bathroom pipe shaft is fixed to the bathroom. Similar inventions currently use sewage and waste water combined to achieve same-floor drainage without lowering the floor, which in most cases cannot meet relevant regulations and the requirements of local sanitation departments. For example, the "Code for Design of Building Water Supply and Drainage" (GB50015-2003) (2009 edition) has relevant regulations on the selection of drainage systems: 4.1.2 A drainage system that separates domestic sewage and domestic wastewater should be used in the following situations in buildings: 1) When the nature of the building's use requires high sanitary standards; 2) When the amount of domestic wastewater is large and the sanitation department requires that domestic sewage be treated in a septic tank before being discharged into urban drainage pipes; 3) When domestic wastewater needs to be recycled.

[0004] Therefore, the existing method of achieving same-floor drainage of bathrooms by setting up pipe wells has the following main defects: 1) Drainage on the same floor requires lowering the floor, which is difficult to inspect and maintain; the projection position of bathrooms on different floors is fixed, with poor adaptability and little chance of transformation; 2) The water supply is connected from the outdoors, generally with grooves in the wall or exposed installation on the ceiling; 3) The general water pipes are buried in the wall, and the sewer pipes are buried underground. If the position of the drainage point is changed, civil engineering work is required, which is uneconomical, polluting, and difficult to maintain; 4) The pipe well is arranged sideways, with the bathroom on one side. The relationship between the pipe well and the bathroom is fixed, with poor adaptability and little chance of transformation. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the same-floor drainage of existing toilets and provide a four-way integrated drainer and an SI system with the four-way integrated drainer as the core, so as to achieve same-floor drainage without lowering the floor while allowing the toilets to be freely arranged around the pipe well.

[0041] The present invention will be described in detail and specifically below through specific examples to provide a better understanding of the present invention, but the following examples do not limit the scope of the present invention.

[0042] In some embodiments, the current drainage on the same floor requires the slab to be lowered, which makes maintenance difficult, the projection position of the toilets on different floors is fixed, the adaptability is poor, and the opportunity for transformation is small. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, based on the existing integrated toilet products on the market, a four-way integrated drain is provided, which mainly includes a sewage and waste diversion pipe well 100 and a sewage riser 210, a wastewater riser 310, a ventilation riser 410 and a ring-shaped wastewater drainage pipe 330 arranged in the sewage and waste diversion pipe well 100.

[0043] Specifically, the sewage riser 210, the wastewater riser 310 and the ventilation riser 410 are arranged in a herringbone shape in the sewage-waste diversion pipe well 100, and the annular wastewater drainage pipe 330 is arranged at the bottom of the sewage-waste diversion pipe well 100, and the annular wastewater drainage pipe 330 is connected to the drainage inlet of the wastewater riser 310.

[0044] The sewage riser 210 can be directly connected to the four directions of the sewage and waste diversion pipe well 100 through the six-way connector 220 provided thereon, so that the sewage riser can be connected to the sewage equipment in four directions without hindrance. The annular wastewater drainage pipe 330 is arranged in a ring shape around the sewage riser 210, the wastewater riser 310, and the ventilation riser 410, and the pipes around it can be directly connected to the wastewater drainage, so that drainage equipment can be connected to the pipe well on all sides. Here, the direct connection refers to a point-to-point linear connection, such as using a straight pipe to connect to a toilet sewage pipe or other drainage equipment, rather than using multiple bends to turn and connect.

[0045] The sewage riser 210, wastewater riser 310 and ventilation riser 410 in the four-way integrated drain are arranged in a compact triangular shape. Under the premise of meeting the installation spacing requirements of various construction requirements, the pipe well area is only increased by 0.032 m compared with the traditional I-type layout. 2 The area of ​​the I-type layout pipe well is 0.414 m 2 ; L-shaped layout pipe well area 0.449 m 2 ; The area of ​​the pipe well in the shape of a triangle is 0.446 m 2 ,like Figure 1 The four-way integrated drain solution not only achieves four-way sewage and waste diversion, but also increases water supply pipes and meets the technical requirements of same-floor drainage without lowering the slab, greatly improving the efficiency and flexibility of space utilization and bringing more possibilities to SI system buildings.

[0046] In some of these embodiments, Figure 3 、 Figure 5 and Figure 13 As shown, the sewage and waste diversion pipe shaft 100 is arranged in the center of the room (household space), and the water supply and drainage equipment can be flexibly arranged in the surrounding space, for example, it can be arranged close to the structural secondary beam 003. By arranging the sewage and waste diversion pipe shaft 100 in the center of the room close to the secondary beam, the sewage and waste diversion pipe shaft 100 can be connected to the bathroom in all four directions, which is suitable for new construction and reconstruction with decentralized water supply and drainage function requirements. The centering refers to setting the sewage and waste diversion pipe shaft 100 in the center of a room in a house or apartment, rather than just referring to a bathroom or a separate room unit. By arranging the sewage and waste diversion pipe shaft 100 in the center of the room, it can radiate to the four directions of the room to connect the water supply and drainage equipment in multiple bathrooms and / or kitchens.

[0047] In some of these embodiments, Figure 2 、 Figure 4 and Figure 5 As shown, the sewage and waste diversion manhole 100 includes a manhole wall, a countersill 101, an installation port 103, and an inspection port 104. As a preferred embodiment, the interior space of the manhole wall is 530 mm long and 420 mm wide, and is equipped with a wastewater riser 310 with a diameter of 110 mm, a sewage riser 210 with a diameter of 110 mm, and a ventilation riser 410 with a diameter of 110 mm. Corresponding riser sleeves are provided on the floor. If used in a multi-story building, the wastewater riser 310 can adopt a diameter of 75 mm, and the manhole size can be reduced accordingly. A water supply pipe can be arranged in the gap on the side of the ventilation riser 410.

[0048] Specifically, the anti-ridge 101 is located at the bottom of the pipe shaft wall, and the top of one side is provided with the installation opening 103. The height of the anti-ridge 101 is 50-200 mm; preferably, its height is 50-200 mm to prevent ground water outside the waste diversion pipe shaft 100 from flowing into the pipe shaft.

[0049] The installation openings 103 are provided at the bottom of the pipe well wall, arranged along the four sides, and facing the six-way connector 220. A drainage interface cover plate 105 is detachably installed at the installation openings 103 to avoid affecting the aesthetics of the room. When a water device needs to be connected to one side, the drainage interface cover plate 105 can be removed.

[0050] The inspection port 104 is located in the middle and lower part of the pipe well wall, arranged along the long side, facing the inspection holes of the sewage riser 210, wastewater riser 310, and ventilation riser 410, that is, corresponding to the inspection port positions of the three risers. Figure 12As shown, a maintenance cover 106 is detachably installed at the inspection port 104 to avoid affecting the aesthetics of the room.

[0051] In some of these embodiments, Figure 2 As shown, the sewage riser 210 is located at the top of the "T" shape, while the wastewater riser 310 and ventilation riser 410 are located on either side of the lower portion, forming a staggered arrangement. To ensure unimpeded connection of the sewage riser 210 in four directions, the six-way connector 220 installed on it is arranged in a facing position, with one of the drainage ports on the six-way connector 220 located between the sewage riser 310 and the ventilation riser 410, so that the four ports of the six-way connector 220 are staggered with the wastewater riser 310 and ventilation riser 410 on either side.

[0052] Specifically, if Figure 2 As shown, the sewage riser 210, wastewater riser 310, and ventilation riser 410 are centrally arranged in the sewage-waste diversion pipe well 100 in a herringbone shape, and each riser has the same distance from the inner wall of the sewage-waste diversion pipe well 100, so as to facilitate the installation of an annular wastewater drainage pipe 330 between the sewage riser 210, wastewater riser 310, ventilation riser 410 and the inner wall of the peripheral sewage-waste diversion pipe well 100.

[0053] The sewage riser 210 has a diameter of 80-150 mm, preferably 110 mm, and is mounted on a six-way connector 220. The upper and lower openings of the six-way connector 220 connect to the sewage riser 210, and its four horizontal connections on the front, back, left, and right sides correspond to the mounting openings 103 around the pipe well. The center of the horizontal connection is no higher than 150 mm above the finished bathroom surface to ensure smooth drainage when connected to the side-flush toilet 600. Each of the four connections is equipped with a sealing cap 221. When connecting the toilet 600, remove the corresponding sealing cap 221 and keep the remaining caps tightly closed to prevent odor from entering the room.

[0054] In some embodiments, such as Figure 5 and Figure 6 As shown, to achieve same-floor drainage without dropping the floor and to allow for the flexible layout of restrooms around the manhole, a pre-installed, same-floor drainage component 320 is installed at the bottom of the sewage and waste diversion manhole 100, corresponding to the position of the wastewater riser 310. The upper and lower riser interfaces of the pre-installed, same-floor drainage component 320 are connected to the wastewater riser 310, and the side interface is connected to the annular wastewater drainage pipe 330.

[0055] In order to facilitate the installation of the same-layer drainage embedded parts 320, the same-layer drainage embedded parts 320 used are required to be compact in structure and occupy a small space. Figure 7 and Figure 8As shown, the non-drop floor same-level drainage embedded part 320 adopts a siphon-type wastewater drainage riser embedded part with its own water seal, which includes a wastewater riser connector and a three-way water seal pipe assembled as one. The specific structure of the embedded part and its working principle are the public technology of our company (application number is 202221216616.9), which will not be repeated here.

[0056] Of course, depending on the needs, this embedded siphonic wastewater drainage riser with a built-in water seal is the preferred but not exclusive option. It can also be replaced by other similar non-drop-slab same-floor drainage interfaces, such as the building same-floor drainage manifold with application number 202010084137.5, the embedded drainage and ventilation manifold with application number 202011574103.0, and the water supply and drainage integrated module with application number 201510149010.6.

[0057] This four-way integrated drainer combines the embedded parts of the siphonic wastewater drainage riser with its own water seal and the integral bathroom products already on the market. Through the same-floor drainage technology without lowering the floor, it can realize the flexible layout of the bathroom around the pipe well. The location, shape and size of the bathroom are not affected by the layout of the rooms on the upper and lower floors.

[0058] In some of these embodiments, Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 、 Figure 11 and Figure 12 As shown, the annular wastewater drainage pipe 330 has a diameter of 30-70 mm, preferably 40-60 mm, and more preferably 50 mm. It is located at the bottom of the sewage and waste diversion manifold 100 and is arranged around the sewage riser 210, wastewater riser 310, and ventilation riser 410. The pipe is equipped with corresponding four-way and five-way connectors. The ventilation riser 410 has a diameter of 80-150 mm, preferably 90-120 mm, and more preferably 110 mm. Its central portion is connected to the sewage riser 210 and wastewater riser 310, respectively.

[0059] Specifically, the annular wastewater drain pipe 330 is connected to the drainage equipment that discharges the wastewater through a number of four-way connectors distributed around the annular pipe. Three-dimensional four-way connectors are distributed around the annular wastewater drain pipe 330, corresponding to the installation ports 103 around the pipe shaft. The upward vertical interface has a sealing cap 332, which is used as a backup for third-party drainage equipment such as washing machines. The horizontal interface is connected to a check valve 331, which passes through the anti-return 101 and has a sealing cap 343 on the other side. When needed, the check valve 331 can be opened directly to the wall or floor drain, or connected to other drainage equipment such as sinks and showers through horizontal drain pipes.

[0060] The annular wastewater drainage pipe 330 is connected to the embedded drainage components 320 for the non-dropping slab on the same level via a five-way connector installed thereon. One of the inner ports of this five-way connector is used to connect to the embedded drainage components 320 for the non-dropping slab on the same level, while the vertical port on the inner port and the outer horizontal port are used to connect to drainage equipment. The upward vertical port has a sealing cap 332, and the horizontal port is installed on a check valve 331. The end of the covered check valve 331 is equipped with a sealing cap 343, similar to the three-dimensional four-way connector.

[0061] The check valve 331 of the five-way and four-way connectors is installed using the thickness of the floor structure from the 001 layer to the room surface layer, such as the waterproof layer, protective layer, slope layer, and floor tiles, totaling approximately 70 mm. The sealing caps used on the interfaces and check valves of the five-way and four-way connectors have the same aperture and adopt the same design to increase interchangeability.

[0062] Based on the four-way integrated drainer, such as Figure 10 As shown, an SI system with the four-way integrated drainer as the core is also provided. The SI system is a water supply and drainage system of a building, which mainly includes the sewage and waste diversion pipe well 100, the sewage system 200, the wastewater system 300, and the exhaust pipe 400. The four-way integrated drainer is formed by rationally arranging the various structural components in the sewage and waste diversion pipe well 100, the sewage system 200, the wastewater system 300, and the exhaust pipe 400.

[0063] Specifically, a manhole equipped with this four-way integrated drain is typically installed in each bathroom or kitchen. The six-way connector 220 and the annular wastewater drain pipe 330 on the four-way integrated drain directly connect the sewage and wastewater drains in the bathroom and kitchen in at least one direction. This four-way integrated drain achieves same-floor drainage without lowering the slab, meeting relevant regulations and the requirements of local sanitation departments.

[0064] Furthermore, when at least two bathrooms and / or kitchens are adjacent, they share a pipe shaft with the four-way integrated drain. This means that at least two adjacent bathrooms and / or kitchens share the four-way integrated drain, and the six-way connector 220 and the annular wastewater drain pipe 330 on the four-way integrated drain can directly connect the sewage and wastewater drainage in each bathroom and / or kitchen in at least one direction. This allows for a flexible layout of the bathroom pipe shaft and the bathroom and / or kitchen, ensuring that the location, shape, and size of the bathroom and / or kitchen are not affected by the layout of the rooms above and below. The adjacent bathrooms and / or kitchens include bathrooms or kitchens that are adjacent in front and behind, left and right, or arranged back to back against a wall.

[0065] In some of the embodiments, the SI system with a four-way integrated drainer as the core also includes a water supply system 500 arranged in the sewage and waste diversion pipe well 100, and the water supply system 500 consists of a water supply pipe 501, a water supply valve 502 and a water meter 503, and the water supply valve 502 and the water meter 503 are installed on the water supply pipe 501.

[0066] Specifically, the space outside the exhaust riser 410 and the sewage riser 210 is fully utilized, and the water supply pipe 501 is set in the space outside the sewage riser 210 and the ventilation riser 410, and is arranged near the corner of the pipe shaft to avoid obstructing the connection of the sewage horizontal pipe. The installation height of the water meter 503 is the same as the inspection port 104, which is convenient for operation and can be used for remote meter reading. The installation height of the water supply valve 502 is the same as the inspection port 104, which is convenient for operation. The upper and lower water pipes in the sewage and waste diversion pipe shaft 100 are all open pipes, which are not restricted by the interface position and can be freely connected to various water-using equipment. At the same time, they are easy to install, inspect and maintain.

[0067] In addition, it should be noted that in order to fully utilize the space in the waste diversion pipe well 100, Figure 6 and Figure 10 As shown, the water supply pipe 501 and the non-drop floor same-level drainage embedded parts 320 on the wastewater system 300 are respectively arranged in the left and right side spaces of the ventilation riser 410.

[0068] Specifically, the water supply pipe 501 is installed in the space to the right of the sewage riser 210 and the ventilation riser 410, and the non-dropping floor drainage embedded component 320 is installed in the space to the left of the sewage riser 310 and the sewage riser 210. The non-dropping floor drainage embedded component 320 and the water supply pipe 501 are arranged on the left and right relative to the ventilation riser 410 in the middle, and the non-dropping floor drainage embedded component 320 is located on the inside of the annular wastewater drainage pipe 330, while the water supply pipe 501 is located at the corner outside the annular wastewater drainage pipe 330.

[0069] Finally, if Figures 7 to 12 As shown, a construction method of an SI system using a four-way integrated drainer as the core is provided, which specifically includes the following steps:

[0070] 1) Set the pipe well position in the center of the floor structure 001 near the structural secondary beam 003, and install the embedded parts of the siphon type wastewater drainage riser with self-sealing water seal in the corresponding wastewater reserved slot;

[0071] 2) Install an annular wastewater drainage pipe 330 at the corresponding position in the pipe well. Horizontal check valve interfaces and vertical backup drainage interfaces are distributed around the annular wastewater drainage pipe 330.

[0072] 3) Install the six-way connector 220 in the corresponding sewage reserved slot in the pipe well;

[0073] 4) Then install the wastewater riser 310 on the embedded parts of the siphonic wastewater drainage riser, install the sewage riser 210 on the six-way connector 220, and install the ventilation riser and water supply pipe in the corresponding reserved slots in the pipe well;

[0074] 5) Build the anti-slope 101 at the location of the pipe well and the side drain 004 corresponding to the bathroom;

[0075] 6) Connect the toilet 600 and the six-way connector 220 via the hose 601, and finally use covers to close the pipe well installation port 103 and the inspection port 104 respectively.

[0076] In addition, in order to fully reflect the actual application effect of the SI system with four-way integrated drain as the core, such as Figure 13 As shown, based on the four-way integrated drainer with a centrally arranged herringbone-shaped sewage and waste diversion pipe well, the specific application scenarios of the SI system in various different modes are listed as examples when the relationship between the pipe well and the space in which it is located is fixed.

[0077] like Figure 14 The figure below shows a floor plan of the SI system in a standard room model. Within a single apartment, a wastewater diversion manifold is centrally located, creating two independent standard rooms. These two adjacent rooms share a four-way integrated drain. This standard room model can be applied to hotels or B&Bs.

[0078] like Figure 15 and 16 The figure shows the application plan of the SI system in an apartment model. The sewage and waste diversion pipe well is arranged in the center of a unit space, forming two independent apartment spaces. The kitchens and bathrooms of the two apartments are arranged around the sewage and waste diversion pipe wells. All water supply and drainage share a four-way integrated drain. Specifically, according to the layout of the kitchen and bathroom, the following can be formed: Figure 15 and 16 Two apartment models. This apartment model can be applied to apartment buildings.

[0079] like Figure 17 and Figure 18 The figure shows the SI system's floor plan for one- and two-bedroom units. Within each unit, a centrally located wastewater manhole is provided, along with two separate bathrooms and, if needed, one or two separate kitchens. The kitchens and bathrooms are arranged around the manhole, and all water supply and drainage systems share a four-way integrated drain. This one- and two-bedroom model is suitable for residential buildings.

[0080] The above detailed description of the application is only as an example, and the application is not limited to the above described specific embodiments. Any equivalent modifications and substitutions made by those skilled in the art to the application are also within the scope of the application. Therefore, equivalent transformations and modifications made without departing from the spirit and scope of the application should be covered within the scope of the application.
