Description

  The present invention relates to a basic through-pipe structure that is unlikely to generate a negative pressure in a drain pipe without a vent valve and can be constructed even when a pipe space is small.

  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, An object of the present invention is to provide a basic through-piping structure that can be easily constructed even if the piping space is narrow.

In order to solve the above-described problems, a first through-pipe structure according to the present invention has a small swirl flow generating joint disposed inside a house foundation, and a small swirl flow generating joint and a drain on the outside of the house foundation. place the basins, through the inside of small swirl flow generation sidewall which is formed in connection opening of the joint of the underlying with connecting upstream drainage pipe, the foundation bottom which is formed in connection opening of the small circular flow generating joint The upstream end of the foundation through drainage pipe is connected via a large bend pipe, and the downstream end of the foundation through drainage pipe is connected to the connection port formed on the side wall of the small swirl flow generating joint outside the foundation. The upstream end of the pipe is formed at the connection port formed at the lower end of the small swirl flow generating joint, the downstream end of the tube is formed at the connection port formed at the side wall of the drainage pipe, and the lower part of the drainage pipe is formed. and the outdoor discharge pipe to the lower connection opening, characterized in that it also respectively connected It is.

The second basic through piping structure of the present invention, a small whirling flow generating joint while placed inside the foundation of the house, to place the swirling flow type catch basins for generating a swirling flow to the outside of the foundation of the house ya The upstream end of the foundation through drainage pipe that connects the upstream drainage pipe to the connection port formed on the side wall of the small swirl flow generating joint and penetrates the foundation to the connection port formed at the lower end of the small swirl flow generation joint And connecting 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 flow drainage basin, and the lower part of the swirling drainage basin An outdoor drain pipe is connected to the lower connection port formed in the above.

  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 drains through the basic through drain pipe. When a swirl flow is generated by the small swirl flow generating joint, an air core is formed at the center of the swirl flow, and the drainage that generated this swirl flow smoothly flows into the basic through drainage pipe. In addition, 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. Since the swirling flow generated in the generating joint is maintained without decreasing and smoothly flows down the large bend pipe and flows through the foundation through drainage pipe, it becomes more difficult to be blocked and the effect of preventing the sealing water breakage is further improved. 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.

And a small swirl flow generating joint and a drainage basin are arranged outside the foundation of the house, and the downstream end of the basic through drainage pipe is connected to the connection port formed on the side wall of the small swirl flow generating joint outside the foundation. The upper end of the pipe at the connection port formed at the lower end of the small swirl joint, the lower end of the tube at the connection port formed at the side wall of the drainage pipe, and the lower part formed at the lower part of the drainage pipe Since the outdoor drainage pipes are connected to the connection ports, the drainage that flows into the small swirl-flow generating joint arranged inside the foundation and turns into a swirling flow passes through the foundation through drainage pipe and goes outside the foundation. It flows into the small swirl flow generating joint arranged in the flow, and again turns into a swirl flow, flows into the drainage basin through the pipe, and is drained to an outdoor drain pipe (hereinafter referred to as an outdoor drain pipe). If a small swirl flow generating joint is placed between the foundation through drain pipe and the drainage in this way, the small swirl flow generating joint forms a swirl flow. Can be ensured, and the water seal destruction of each water facility can be sufficiently prevented.

Similarly, a small swirl flow generating joint is disposed inside the foundation of the house, and a swirl type drainage basin that generates swirl flow is disposed outside the house foundation, and is formed on the side wall of the small swirl flow generating joint. Connect the upstream drainage pipe to the connection port, and connect the upstream end of the basic through drainage pipe that penetrates the foundation to the connection port formed at the lower end of the small swirl flow generating joint via a large bend pipe. , with connecting downstream end of the foundation through the drainage tube to the upper connection opening formed in the upper portion of the side wall of the swirling flow type catch basins, outdoor drain pipe at the bottom connecting port formed in a lower portion of the swirling flow type catch basins the second basic through piping structure of the present invention connected also, waste water has flowed into the small circular flow generating joint from the upstream side drain pipe becomes swirling flow, an upper connection opening of the swirling flow type catch basin through the foundation through drainpipe Flows into the drainage basin and becomes a swirl flow again to the outdoor drainage pipe It is discharged to the downstream side. Thus, since a swirl flow is generated even in a swirl type drainage basin, there is no need to worry about blockage in the drainage basin.

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

  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 an upper part formed on the upper side wall of the swirl type drainage basin 7. The downstream end of the foundation penetration drain pipe 5 that penetrates the foundation 20 is connected to the 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. Two upstream drain pipes 4 and 4 are connected to the upper and lower connection ports 1a and 1a of the small swirl flow generating joint C, and a rising pipe 9 is connected to the opening 1c.

As shown in FIG. 14, the small swirl flow generating joint C has two connection ports 1 a and 1 a connecting two upstream drain pipes 4 and 4, and one side of the cylinder 10 b of the upper member 1. It is projected to bend and bend.
Since the basic through-pipe structure and the other structure of the small swirl flow generating joint C of this embodiment are the same as those of the embodiment shown in FIGS.

In such a basic through-pipe structure using a small swirl flow generating joint C, it is possible to arrange two upstream drain pipes 4 and 4 in parallel in the vertical direction while reliably preventing water seal destruction. As a result, piping space can be secured even in a small space.
In addition, when the several drainage pipe 8 is arrange | positioned on the floor, it goes without saying that this small swirl flow generating joint C may be disposed on the floor.

  FIG. 18 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 according to this embodiment has a small swirl flow generating joint D shown in FIG. 15 instead of the small swirl flow generating joint A disposed under the floor of the embodiment shown in FIGS. Then, the two upstream drainage pipes 4 and 4 are connected to the left and right connection ports 1a and 1a of the small swirl flow generating joint D.

In this small swirl flow generating joint D, as shown in FIG. 15, the connection ports 1a, 1a connecting the two upstream drain pipes 4, 4 are respectively provided on one side of the cylinder 10b of the upper member 1 and on the opposite side thereof. It is projected so as to bend and bend.
Since the other structure of this basic through-pipe structure and the small swirl flow generating joint D is the same as the pipe structure of FIGS. 6 to 8 and the small swirl flow generating joint B shown in FIGS. Description is omitted.

In such a basic through-pipe structure using the small swirl flow generating joint D, the upstream drain pipes 4, 4 need to be arranged from both the left and right sides in parallel with the foundation 20 of the house because of the piping space. In addition, it is possible to reliably prevent the sealing water from being destroyed only by arranging one small swirl flow generating joint D.
The lid 3 attached to the opening 1c of the small swirl flow generating joint D is removed, and the rising pipe 9 is connected to the opening 1c as described above, and the upper end of the rising pipe 9 is If connected to one of the small swirl flow generating joints A, B, C, D to which the upper drainage pipe 8 is connected, the drainage from the upper floor water facility is smoothly blocked without being blocked. Needless to say, it is discharged to 60c.

  FIG. 19 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 E shown in FIG. 16 is disposed instead of the small swirl flow generating joint B disposed under the floor of the embodiment shown in FIG. An upstream drain pipe 4 and a rising pipe 9 are connected to the connection port 1a and the opening 1c of the small swirl flow generating joint E, respectively.
