Abstract

<P>PROBLEM TO BE SOLVED: To provide a compact swirl generating joint which is set even in a narrow space and prevents the water sealing of a trap from being broken because a swirl does not weaken and securely forms an air core, and also to provide a foundation penetrating piping structure using the same. <P>SOLUTION: A connection port 1a connected with an upstream side drain pipe 4 is displaced and formed on one side of the upper part 1b of the side wall of a joint A, and a tapered inner surface 2b which is downwardly narrowed is formed at the lower part of the joint A, and a connection port 2a connected with a downstream side drain pipe 5 is formed at the lower end of the tapered inner surface 2b. Since the connection port 1a connected with the upstream side drain pipe 4 is displaced and formed on one side of the upper part 1b of the side wall and the tapered inner surface 2b is formed at the lower part of an inner surface, drainage water flows downward swirlingly and increases a flow rate by swirling around the peripheral surface of the tapered inner face 2b, and becomes a vigorous swirl and is smoothly discharged from the connection port 2a to the downstream side drain pipe 5 so that clogging is not caused. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a small swirl flow generating joint and a basic through-pipe structure using the same, in which a negative pressure is unlikely to be generated in a drain pipe without a vent valve, and the pipe space can be narrowed. .

  In the conventional underfloor piping system, when the amount of drainage increases and the water level in the piping rises, the bent part and step part of the drainage pipe are blocked by a large amount of drainage, and the ventilation in the pipe is blocked, generating negative pressure, This negative pressure has the problem that the sealing water in the traps of water facilities such as washbasins, kitchens, bathrooms and toilets is destroyed.

  In order to alleviate and absorb such pressure fluctuations in the underfloor piping system, a rising pipe is installed in the middle of the drainage pipe from the water facility on the floor to the drainage header, and is extended above the building, for example, at the end of the gable roof Measures were taken such as exposing the upper end of the vent pipe to the outside through walls and the like.

  However, as described above, the one that is exposed to the outside by extending the rising pipe upward is breathable, so that it can be returned to normal pressure even if negative pressure is generated in the drainage pipe. Since the rising pipe is exposed to the outside through the wall surface, there is a problem that the construction is troublesome and expensive, and the appearance of the building is damaged. In addition, recent homes sometimes cannot secure a space for installing the riser pipe depending on the position of the water facility.

  In addition, there is a vent valve attached to the upper end of the riser pipe, but this vent valve uses a rubber plate as a valve body, so that the valve body becomes sticky due to moisture from the drain pipe, There was a problem that it stuck to the seat and did not operate smoothly, and the rustling sound when the valve body opened and closed was worrisome. Moreover, in order to install this vent valve, there has been a problem that it is necessary to pour a wall.

  In order to solve such a problem, a vertical pipe part having a vertical pipe connection port in the lower part and a pipe joint main body formed integrally with a merged inflow pipe part connected to the vertical pipe part are provided. The merging portion communicating with the vertical pipe portion is a swirl flow generating bulging portion that is detoured more than half a circumference along the outer periphery of the vertical pipe portion from the merging inflow pipe portion side toward the vertical pipe portion and gradually reduces the bulging amount. And a merging pipe joint in which a weir wall is formed between the swirling flow generating bulge and the vertical pipe has been proposed (Patent Document 1).

Although this joint pipe joint has been able to solve the conventional problem, it is bulky and requires a large burial space. In recent years, there has been a problem that it is difficult to construct a pipe under the floor of a house where the pipe space is small. It was. In addition, the swirling flow generated by the swirling flow generating bulge part decreases the flow velocity while swirling the inner wall of the vertical pipe part, so that the formation of the air core is insufficient, and the sealing failure of the trap is satisfactorily prevented. There was also the problem that it became difficult.
Japanese Patent Laid-Open No. 8-232312

  The present invention was made to cope with the above-mentioned problem, and since the swirl flow does not decay and the air core is reliably formed, it is possible to sufficiently prevent the sealing failure of the trap accompanying the negative pressure generation of the drain pipe, The problem to be solved is to provide a small swirl flow generating joint that can be easily installed even if the piping space is small, and a basic through-pipe structure using the same.

  In order to solve the above problems, a small swirl flow generating joint according to the present invention is a small joint that generates a swirl flow, and the connection port connecting the upstream drain pipe is displaced to one side of the side wall of the joint. The tapered inner surface is formed in the lower part of the joint, and a connection port for connecting the downstream drainage pipe is formed at the lower end of the tapered inner surface.

  In the small swirl flow generating joint of the present invention, an upper member in which a connection port for connecting the upstream drain pipe is formed, and a lower member in which a connection port for connecting the downstream drain pipe is formed at the lower end of the tapered inner surface, It is preferable that the upper member and the lower member are fitted and integrated. And depending on the arrangement of the water equipment, it is displaced to one side of the side wall of the upper member, and a small swirl flow generating joint in which a plurality of upper and lower connection ports for connecting the upstream drain pipe are formed, and an upstream drain pipe are connected. A small swirl flow generating joint formed with a plurality of connecting ports that are offset from one side of the side wall of the upper member and a small connecting port that connects the upstream drain pipe is formed obliquely upward It is preferable to use different swirl flow generating joints, and it is more preferable that an opening is provided at the upper end of the upper member, and a lid is attached to the opening.

  On the other hand, the basic through-pipe structure according to the present invention has the small swirl flow generating joint disposed inside the foundation of the house and a swirl type drainage basin that generates swirl flow outside the foundation. The upstream drain pipe is connected to the connection port formed on the side wall of the flow generating joint, and the upstream end of the foundation through drain pipe passing through the foundation to the connection port formed on the lower end of the tapered inner surface of the small swirl flow generating joint. Connect the downstream end of the basic through drainage pipe to the upper connection port formed in the upper part of the side wall of the swirling drainage basin, and connect the outdoor drainage pipe to the lower connection port formed in the lower part of the swirling drainage basin. It is characterized by that.

  In the foundation through-pipe structure of the present invention, the small swirl flow generating joint is arranged inside the foundation of the house, and the small swirl flow generating joint and the drainage are arranged outside the foundation, and the small swirl inside the foundation is arranged. Connect the upstream drain pipe to the connection port formed on the side wall of the flow generation joint, and the upstream end of the foundation through drain pipe that penetrates the foundation to the connection port formed at the lower end of the tapered inner surface of the small swirl flow generation joint. The downstream end of the foundation through drain pipe is connected to the connection port formed on the side wall of the small swirl flow generating joint outside the foundation, and the upstream side is connected to the connection port formed at the lower end of the tapered inner surface of the small swirl flow generating joint. The upstream end of the large bend pipe that rises in the direction of approximately 90 ° is connected to the connection port formed in the side wall of the drainage basin, and the downstream end of the large bend pipe is connected to the lower connection port formed in the lower part of the drainage basin. It is also preferable to connect each outdoor drain pipeIt is also preferable to remove the lid attached to the opening of the upper member of the small swirl flow generating joint according to claim 6 and to connect a rising pipe rising upstairs to the opening. The lid attached to the opening of the upper member of the small swirl flow generating joint according to claim 6 is removed, and a rising pipe that rises upstairs is connected to the opening, and the upper end of the rising pipe is It is also preferable to connect to the connection port formed at the lower end of the tapered inner surface of the swirl flow generating joint and to connect the upper drainage pipe to the connection port formed on the side wall of the small swirl flow generating joint. Furthermore, the upstream drainage pipe connected to the connection port formed on the side wall of the small swirl flow generating joint and the rising pipe rising to the floor are connected via a large bending pipe rising in the approximately 90 ° direction on the upstream side. The upper end of the riser pipe is connected to the connection port formed at the lower end of the tapered inner surface of another small swirl flow generating joint, and the drainage on the floor is connected to the connection port formed on the side wall of the small swirl flow generating joint. It is also preferable to connect a pipe, and the upstream end of the basic through drainage pipe and the connection port formed at the lower end of the small swirl flow generating joint are connected via a large bend pipe that rises in the direction of approximately 90 ° on the upstream side. More preferably.

  Since the small swirl flow generating joint of the present invention is very compact compared to the conventional confluence pipe joint, it can be installed even if the piping space under the floor is small, as is often seen in recent housing circumstances. it can. Even if drainage flows from the upstream drainage pipe, the connection port connecting the upstream drainage pipe is formed to be offset from the side wall, so the drainage flows downward while swirling around the vortex. To go. At this time, a tapered inner surface that is reduced in diameter downward is formed at the lower part of the inner surface of the small swirl flow generating joint, so that the drainage swirling around the vortex swirls around the circumferential surface of the tapered inner surface. Rather, the flow rate is increased, and a more vigorous swirling flow is smoothly drained from the connection port to the downstream drain pipe. When a swirling flow is generated in this manner, an air core is formed at the center of the swirling flow, and the drainage smoothly flows into the downstream drainage pipe. It becomes difficult to generate a negative pressure, and it is possible to reliably prevent the sealing water from being destroyed unless a large amount of water is drained.

  The upper member and the lower member include an upper member formed with a connection port for connecting the upstream drain pipe and a lower member formed with a connection port for connecting the downstream drain pipe to the lower end of the tapered inner surface. Since the small swirl flow generating joint in which is integrally fitted is formed as a separate body, the taper inner surface is much easier to mold than when integrally molded, and the cost can be reduced.

  In addition, the small swirl flow generating joint, which is displaced to one side of the side wall of the upper member and has a plurality of upper and lower connection ports for connecting the upstream drain pipe, reliably prevents the sealing failure of each water facility. However, since a plurality of upstream drain pipes can be joined to one small swirl flow generating joint, when the piping space of a house is very narrow, a plurality of upstream drain pipes are arranged in parallel vertically. By connecting to a small swirl flow generating joint, piping space can be secured.

  In addition, the small swirl flow generating joint in which the connection port for connecting the upstream drain pipe is displaced to the side opposite to one side of the side wall of the upper member is formed in the same manner as described above to prevent the sealing failure. However, since a plurality of upstream drain pipes can be joined to one small swirl flow generating joint, the use of this small swirl flow generating joint allows the upstream drain pipes to be arranged on both the left and right sides. Become.

  In addition, the small swirl flow generating joint in which the connection port for connecting the upstream drain pipe is formed obliquely upward can give the upstream drain pipe a gradient while preventing the sealing water from being broken.

  Furthermore, in the small swirl flow generating joint in which an opening is provided at the upper end of the upper member and a lid is attached to the opening, a rising pipe that rises upstairs is connected to the opening when the lid is removed. In addition, maintenance and the like can be performed from the opening.

  On the other hand, in the basic through-pipe structure of the present invention, the waste water that flows into the small swirl flow generating joint from the upstream drain pipe becomes a swirl flow, and passes through the basic through drain pipe from the upper connection port of the swirl drain pipe. It flows into the interior and becomes a swirl flow again and is drained downstream of an outdoor drain pipe (hereinafter referred to as an outdoor drain pipe). When a swirl flow is generated by the small swirl flow generating joint as described above, an air core is formed at the center of the swirl flow, and the waste water that generated this swirl flow smoothly flows into the basic through drainage pipe. The foundation through drain pipe is not easily blocked, and a swirl flow is generated even in the swirl type drainage basin, so there is no need to worry about clogging in the drainage basin. Therefore, according to the basic through-pipe structure of the present invention, it is easy to ensure ventilation in the pipe, and since negative pressure is hardly generated in the upstream drain pipe due to the blockage, water in toilets, washstands, bathrooms, kitchens, etc. It is possible to prevent the sealing water damage of the equipment.

  The small swirl flow generating joint is arranged inside the foundation of the house, and the small swirl flow generating joint and the drainage are arranged outside the foundation, and are formed on the side wall of the small swirl flow generating joint inside the foundation. The upstream drainage pipe is connected to the connection port, the upstream end of the foundation through drainage pipe that penetrates the foundation through the connection port formed at the lower end of the tapered inner surface of the small swirl flow generating joint, and the small swirl flow outside the foundation. The downstream end of the basic through drainage pipe is connected to the connecting port formed on the side wall of the generating joint, and the upstream end of the small swirling flow generating joint is formed in the direction of approximately 90 ° upstream from the connecting port formed on the lower end of the tapered inner surface. Connect the upstream end of the bent pipe, the downstream end of the large bent pipe to the connection port formed in the side wall of the drainage basin, and the outdoor drainage pipe to the lower connection port formed in the lower part of the drainage basin. The foundation through-piping structure is small and placed inside the foundation. The wastewater that flows into the swirl flow generating joint and turns into a swirl flow passes through the foundation through drainage pipe and flows into the small swirl flow generating joint arranged outside the foundation, and again turns into a swirl flow and passes through the large bend pipe. Then, it flows into the drainage basin and drains to the outdoor drainage pipe. If a small swirl flow generating joint is arranged between the foundation through drainage pipe and the drainage in this way, the small swirl flow generating joint forms a swirl flow, so that a swirl flow is generated as in the piping structure described above. Even without using a special swirling flow drainage basin, it is possible to ensure ventilation in the pipe with a conventional general drainage basin, and to sufficiently prevent the sealing damage of each water facility.

  Moreover, while removing the cover body attached to the opening part of the upper side member of the small swirl flow generating joint according to claim 6, the basic through-pipe structure for connecting the rising pipe rising to the floor to the opening part is as follows. Since the riser pipe can be connected directly above the small swirl flow generating joint by simply removing the lid, even a narrow space can be drained smoothly without blocking.

  Then, the lid attached to the opening of the upper member of the small swirl flow generating joint according to claim 6 is removed, and a rising pipe that rises upstairs is connected to the opening, and the rising pipe The upper end is connected to a connection port formed at the lower end of the tapered inner surface of the small swirl flow generating joint according to any one of claims 1 to 6, and the connection formed on the side wall of the small swirl flow generating joint. The basic through-pipe structure that connects the upper drainage pipe to the mouth is a swirl flow that flows from the drainage pipe where the drainage from the upper-floor water facilities merges into the small swirl flow generating joint, and it rises up without being blocked. Run down the tube. In addition, as mentioned above, coupled with the fact that the drainage from the water facility on the first floor is difficult to block, the drainage from the water facility on the first floor and the water facility on the upper floor despite the space saving. It can be smoothly merged into one place without blocking and drained to an outdoor drain pipe.

  On the other hand, the upstream drainage pipe connected to the connection port formed on the side wall of the small swirl flow generating joint and the rising pipe rising to the floor are connected via a large bending pipe rising in the direction of approximately 90 ° on the upstream side. The upper end of the riser pipe is connected to the connection port formed at the lower end of the tapered inner surface of another small swirl flow generating joint, and the drainage on the floor is connected to the connection port formed on the side wall of the small swirl flow generating joint. The basic through-pipe structure connecting the pipes is that the wastewater that flows into the small swirl flow generating joint from the drainage pipe on the floor turns into a swirl flow, flows down the riser pipe without being blocked, and passes through a large bend pipe that is difficult to block Since it flows to the upstream drainage pipe, drainage from toilets and washrooms on the floor can be drained more smoothly without obstruction.

  In particular, when the upstream end of the basic through drainage pipe and the connection port formed at the lower end of the small swirl flow generating joint are connected via a large bend pipe that rises in the direction of approximately 90 ° on the upstream side, The swirl flow generated by the small swirl flow generating joint smoothly flows down the upstream part of the large bend pipe and foundation through drainage pipe, flows through the basic through drainage pipe, and flows into the swirl type drainage basin. As a result, it becomes difficult to prevent the sealing water from being destroyed.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  1 is a perspective view of a small swirl flow generating joint according to an embodiment of the present invention, FIG. 2 is a perspective view of an upper member that is a constituent member of the joint, and FIG. 3 is a perspective view of a lower member that is a constituent member of the joint. 4 is a plan view of the joint, FIG. 5 is a cross-sectional view of the joint (cross-sectional view taken along the line aa in FIG. 4), and FIG. 6 is a basic through-pipe structure according to an embodiment of the present invention. FIG. 7 is a plan view of the piping structure, and FIG. 8 is an exploded sectional view of a swirling drainage used in the piping structure.

  A small swirl flow generating joint A shown in FIG. 1 is a synthetic resin pipe joint composed of two members, an upper member 1 shown in FIG. 2 and a lower member 2 shown in FIG. As shown in FIG. 2, it is arranged inside the cloth foundation 20 of the house.

  As shown in FIGS. 2 and 5, the upper member 1 is composed of a joint body 1b and a connection port 1a for connecting the upstream drain pipe 4, and the connection port 1a is formed as shown in FIG. It protrudes so as to bend and bend on one side of the upper part of the joint body 1b. In this connection port 1a, the inner diameter of the tip end portion 10a is the same as the outer diameter of the upstream drain pipe 3 (VU75 pipe), and the inner diameter of the bent portion 11a does not cause a step when the upstream drain pipe 4 is connected. It is formed to be equal to the inner diameter of the upstream drain pipe 4. The waste water that has flowed in from the upstream drain pipe 4 becomes a trigger for generating a swirling flow at the bent portion 11a of the connection port 1a, and flows into the joint main body 1b while swirling approximately 1/4 turn.

  The joint body 1b includes a cylinder 10b having a diameter of about 100 mm, a dome portion 11b formed at the tip of the cylinder 10b, and a fitting portion 12b formed at the lower end of the cylinder 10b. In order to prevent the drainage that is generating the swirling flow that has been routed through the connection port 1a from being broken by contacting the dome portion 11b, and to form a more complete swirling flow, a round with less resistance It has a dome shape.

  As shown in FIG. 4, the fitting portion 12b formed at the lower end of the joint body 1b has a larger diameter than the cylinder 10b of the joint body 1b, and fits a fitted portion 2c of the lower member 2 described later. In this case, the inner surface of the cylinder 10b and the inner surface of the tapered inner surface 2b of the lower member 2 are formed so as to be flush with each other.

  The lower member 2 shown in FIG. 3 includes an annular fitted portion 2c, a tapered inner surface 2b, and a connection port 2a that connects a basic through drainage pipe 5 that is a downstream drainage pipe. As shown in FIG. 5, the side member 2 and the upper member 1 are bonded by fitting the outer peripheral surface of the fitted portion 2c of the lower member 2 to the inner peripheral surface of the fitting portion 12b of the joint body 1b. It is integrated by watertight adhesive fitting with the agent.

  As shown in FIG. 5, the tapered inner surface 2b is a constricted inner wall surface formed inward from the upper end of the annular engaged portion 2c, and the upper surface has a diameter of the cylinder 10b of the joint body 1b. The inner diameter is about 100 mm which is equal to the inner diameter and is gradually reduced from the bottom to the bottom, and the outer diameter on the lower surface side is formed to be equal to the inner diameter of the VU75 pipe. By forming this tapered inner surface 2b, the waste water that has swirled around the upper member 1 and flowed into the lower member 2 swirls around the peripheral surface of the tapered inner surface 2b to form a more powerful swirling flow. Then, it flows to the connection port 2a.

  The connection port 2a is a cylindrical body formed so as to protrude from the lower end of the tapered inner surface 2b and having an outer diameter equal to the inner diameter of the VU75 pipe, and is fitted inside the upstream end of the basic through drainage pipe 5. It comes to connect. As will be described later, when the connection port 2a and the basic through drainage pipe 5 are connected via the large bend pipe 6, the upstream end of the large bend pipe 6 is connected to the connection port 2a. And when connecting the connection port 2a and the large bend pipe 6 via the short pipe 23 (VU75 pipe), the inner side of the short pipe 23 is inserted in the lower end of the connection port 2a.

  Since the small swirl flow generating joint A composed of the upper member 1 and the lower member 2 described above is formed as a separate body without being integrally formed, the taper inner surface 2b can be formed very easily and the cost can be reduced. . Also, in terms of function, the connection port 1a connected to the upstream drainage pipe 4 is formed to be deviated to one side of the upper portion of the joint body 1b of the upper member 1, and the lower member 2 is formed with a tapered inner surface 2b. Therefore, the wastewater flowing in from the upstream drainage pipe 4 is surely swirled by the upper member 1 while being more compact than the conventional merging pipe joint, and further increases the momentum at the tapered inner surface 2b. It flows to the foundation penetration drain pipe 5. Since an air core is formed at the center of the swirling flow, it is not blocked at the bent part or step part between the upstream drain pipe 4 and the basic through drain pipe 5, and the sealing water can be destroyed without a vent valve. Can be prevented. Moreover, since it is compact, it can also be installed in a recent urban residential area where the piping space is narrow.

  On the other hand, in the foundation through-pipe structure of the present invention shown in FIGS. 6 and 7, the small swirl flow generating joint A is arranged in the boxed portion 21 of the soil concrete inside the cloth foundation 20 of the house. An upstream drain pipe 4 to which a drain pipe from a water facility such as a washroom or a toilet (not shown) is connected is connected to the connection port 1a formed in the swirl flow generating joint A. In addition, a large bent pipe 6 rising in the direction of approximately 90 ° on the upstream side is connected to a connection port 2a formed at the lower end of the small swirl flow generating joint A through a short pipe 23 (VU75 pipe). The large bend pipe 6 is connected to the upstream end of the foundation through drain pipe 5.

  The large bent pipe 6 preferably has a radius of curvature of 100 mm or more. Since such a large bent pipe 6 has a much larger radius of curvature than a 90 ° elbow joint, it is swung by the small swirl flow generating joint A described above. The drainage that has caused the flow smoothly flows down in the large bend pipe 6 and flows into the swirl type drainage basin 7 outdoors through the foundation through drain pipe 5. Therefore, unless a very large amount of drainage flows at a time, the large bend pipe 6 and the foundation through drain pipe 5 are not blocked by the drainage, and the ventilation in the pipe is ensured.

  As shown in FIG. 6, a swirl type drainage basin 7 that generates a swirl flow is embedded in the ground outside the fabric foundation 20, and is formed on the upper side wall of the swirl type drainage drainage 7. A downstream end portion of the foundation penetrating drain pipe 5 that penetrates the foundation 20 is connected to the upper connection port 7a. As shown in FIG. 7, an upstream outdoor drain pipe 70b and a downstream outdoor drain pipe 70c are connected to the lower connection ports 7b and 7c formed in the lower part of the swirl type drainage basin 7. .

  As shown in FIG. 8, the swirling drainage 7 buried in the ground outdoors has a vertical cylindrical body 7d for height adjustment, a lower main body 7e, and an upper lid receiving frame 7f. The lower body 7d for height adjustment is fitted and connected to the upper opening step of the bag main body 7e, and the lid receiving frame 7f is fitted into the vertical cylinder 7d. The lid 7g is attached to the lid receiving frame 7f and assembled.

  And the upper connection port 7a protrudes in the side wall of this vertical cylinder 7d so that it may deviate to one side of the vertical cylinder 7d, and bends a little, and the above-mentioned basic penetration drain pipe is projected to this upper connection port 7a. The downstream end of 6 is connected. Therefore, the waste water that has flowed into the swirling flow type drainage trough 7 from the basic through drainage pipe 6 flows down to the lower dredge main body 7e while generating a swirling flow along the inner peripheral surface of the vertical cylindrical body 7d.

  Lower connection ports 7b and 7c are formed at both ends of the main body 7e. As shown in FIG. 7, an upstream outdoor drain pipe 70b is connected to the lower connection port 7b on the upstream side, and a lower connection port on the downstream side. A downstream outdoor drain pipe 70c is connected to 7c.

  When the swirl type drainage basin 7 is configured as described above, the wastewater flowing in from the foundation through drain pipe 5 generates a swirl flow. Water can be reliably drained to the outdoor drain pipe 70c. When a swirl flow is generated in the swirl type drainage basin 7 as described above, the upstream drain pipe 4, the large bend pipe 6 and the basic through drain pipe 5 are not blocked by the small swirl flow generating joint A as described above. As a result, ventilation over the entire piping is ensured, and the sealing failure of the water facility due to blockage can be reliably prevented.

  FIG. 9 is a schematic overall view of a basic through piping structure according to another embodiment of the present invention.

In the foundation through-pipe structure shown in FIG. 9, the small swirl flow generating joint A is arranged on the upper surface of the solid foundation 22 inside the fabric foundation 20, and the short pipe 23 (VU75 pipe) and the large bent pipe 5 are the solid foundation 22. It is buried inside.
Since the other structure of this basic through piping structure is the same as the basic through piping structure of the embodiment shown in FIGS.

  In this way, in the foundation through-pipe structure in which the short pipe 23 and the large bent pipe 6 are embedded in the solid foundation 22, the small swirl flow generating joint A is arranged on the upper surface of the solid foundation 22 without forming the box opening portion 21. Therefore, it is possible to construct a pipe even in a house where there is almost no height space from the floor to the solid foundation 22.

  FIG. 10 is a schematic overall view of a basic through piping structure according to still another embodiment of the present invention.

In the basic through-pipe structure shown in FIG. 10, the upstream drain pipe 4 connected to the connection port 1a of the small swirl flow generating joint A is connected to one of the large bent pipes 6, and the other of the large bent pipes 6 goes upstairs. By connecting the rising pipe 9 (VU75 pipe) that rises, the upstream drain pipe 4 and the rising pipe 9 are connected, and the upper end of the rising pipe 9 is connected to the connection port 2a of another small swirl flow generating joint A. In addition, a structure in which a drainage pipe 8 (VU75 pipe) on the floor into which drainage from a toilet, washroom, etc. (not shown) on the floor flows is connected to the connection port 1a of the small swirl flow generating joint A. It has become.
Since the other structure of the basic through piping structure of the present embodiment is the same as the basic through piping structure of the embodiment shown in FIGS.

Such a basic through-pipe structure is blocked because the drainage flowing into the small swirling flow generating joint A from the upper drainage pipe 8 becomes a swirling flow and flows down the rising pipe 9 in a state where an air core is formed. In addition, since the drained drainage flows to the upstream drainage pipe 4 through the large bend pipe 6, the flow path from the upstream drainage pipe 4 to the swirling drainage trough 7 as described above. Combined with being difficult to block, drainage from toilets, toilets, etc. on the floor can be drained smoothly without blocking. Therefore, it is possible to cope with a housing situation often seen in recent years, such as setting up a high building in a narrow land space.
It is possible to connect the rising pipe 9 and the upstream drain pipe 4 via an elbow joint or the like, but it is preferable to connect via the large bend pipe 6 in order to prevent the blockage more reliably. .
Further, even if the upstream end of the upstream drain pipe 4 and the lower end of the rising pipe 9 (VU75 pipe) of the basic through-pipe structure shown in FIG. Needless to say, there is an effect.

  FIG. 11 is a schematic overall view of a basic through piping structure according to still another embodiment of the present invention.

  The basic through-pipe structure shown in FIG. 11 is constructed using a small swirl flow generating joint B shown in FIGS. As shown in an exploded view in FIG. 12, the small swirl flow generating joint B is composed of an upper member 1, a lower member 2, a lid receiving frame 3a, and a lid body 3, and includes an upstream drain pipe. 4 is projectingly provided so as to be deflected and bent to one side of a substantially intermediate portion in the height direction of the joint body 1b. As described above, the upper member 1 and the lower member 2 are watertightly connected with an adhesive, and the lid receiving frame 3a is fitted into the opening 1c of the upper member 1, and this lid receiving frame 3a is fitted. The lid 3 is attached to and assembled.

The basic through-pipe structure of the present invention using the small swirl flow generating joint B is as follows. That is, the lid 3 attached to the opening 1c of the upper member 1 of the small swirl flow generating joint B is removed, and the rising pipe 9 rising to the floor is connected to the opening 1c. The upper end of the rising pipe 9 is connected to the connection port 2a of the lower member 2 of another small swirl flow generating joint B arranged on the floor, and the toilet on the floor, the toilet, etc. (not shown) The drainage pipe 8 on the floor into which the wastewater from (1) flows in is connected to the connection port 1a of the small swirl flow generating joint B. Then, the lid 3 attached to the opening 1c of the upper member 1 of the small swirl flow generating joint B to which the upper drainage pipe 8 is connected is removed, and the rising pipe 9 is further provided in the opening 1c. It is connected.
Since the other structure of the basic through piping structure of the present embodiment is the same as the basic through piping structure of the embodiment shown in FIGS.

Such a basic through-pipe structure allows the drainage from the water facility on the first floor and the drainage from the water facility on the floor to be combined into one place and drained to the outdoor drain pipes 60b and 60c without blocking. Therefore, it can cope with the housing in recent urban areas where high buildings are built in a small land space.
In addition, when it is not necessary to connect the riser tube 9 rising to the floor to the opening 1c of the small swirl flow generating joint B, the small swirl described above is performed without removing the lid 3 attached to the opening 1c. What is necessary is just to use the same usage as the flow generation coupling A. And when the necessity for a maintenance etc. arises, what is necessary is just to remove the cover body 3 and to use the opening part 1c as an inspection port.

  FIG. 17 is a schematic overall view of a basic through piping structure according to still another embodiment of the present invention.

  In the basic through-pipe structure according to this embodiment, a small swirl flow generating joint C shown in FIG. 14 is arranged instead of the small swirl flow generating joint B arranged under the floor of the embodiment shown in FIG.
