Description

The present invention relates to a drainage pipe storage structure for storing a vertical pipe part extending in the vertical direction of each instrument drainage pipe extending from each watering instrument in a siphon drainage system .

  In recent years, siphon drainage systems have been developed as drainage systems for high-rise apartments and detached houses. The siphon drainage system has a drainage stand that extends in the vertical direction of the building, equipment drainage pipes (horizontal pipes and dredging pipes) from watering equipment, and a junction joint that connects both pipes. It is preferably arranged on the floor slab with no gradient, the vertical pipe is suspended from the horizontal pulling pipe, and the junction joint is preferably installed on the lower floor, and the horizontal pipe, the junction joint, This is a system that drains water by applying siphon force to the water in the horizontal pipe using the head (head) Hs.

  In such a siphon drainage system, the instrument drain pipe uses a relatively small diameter pipe and basically does not merge with other pipes until the junction joint is reached. The instrument drain pipe is connected to the junction joint as it is.

  However, since the siphon drainage system is drained one by one as described above, there are as many drainage pipes as there are plumbing devices in the water head Hs portion, and there is a problem that the size of the plane fit in this portion becomes large. . In addition, the instrument drain pipe was exposed. For this reason, when it was going to fix and protect each tub tube of this head Hs part, a separate member and construction were needed and the cost increased.

In order to eliminate these disadvantages, a technique has been devised in which the soot tubes are bundled and housed in a cylindrical housing member so as to integrally support and protect the soot tubes (for example, see Patent Document 1) .
JP 2006-207190 A

  By the way, in order to bundle a plurality of soot pipes and connect them to the junction joint, the ends of the bundled soot pipes may be inserted into the connection part of the junction joint. In this case, there is a problem that a gap is generated between the bundled pipes, and the odor from the drainage stack escapes through the gap and leaks to the outside. Moreover, even if a storage member that stores the bundled soot pipes is arranged at the connection part of the junction joint, the odor leaks from the opening of the storage member through the gap between the bundled soot pipes.

The object of the present invention is to integrate the plurality of appliance drain pipes in consideration of the above fact, to prevent leakage of odor from the inside of the storage member, and to further reduce the odor pipe according to the flow rate required by the watering appliance. An object of the present invention is to provide a drainage pipe storage structure capable of optimizing the length of the section .

In order to achieve the above object, a drainage pipe storage structure according to claim 1 of the present invention includes an instrument drainage pipe having one end connected to a watering instrument, and the other end side extending in the vertical direction of the plurality of instrument drainage pipes. Are connected to a cylindrical storage member, and one end portion is connected to a drainage stack extending in the vertical direction, and the other end portion is connected to a lower end portion of the storage member to join the drainage from the watering device. And a closing member that is provided on the upper end side of the storage member, supports the other end side of the plurality of appliance drain pipes, and closes the inside and the outside of the storage member. the provided, the other end of the instrument drain pipe has a vertical pipe section extending in the vertical direction, the drainage flow through the instrument drainage pipe is possible siphon flow, the vertical pipe portion through said closure member, Furthermore, it extends along the storage member and Is interrupted within said housing member.

Next, the operation of the drain pipe storage structure according to claim 1 will be described.
Since the other end side extending in the vertical direction of the plurality of instrument drain pipes is supported by the closing member, the other end sides of the plurality of instrument drain pipes are integrated and integrated. In addition, even if odor from the drainage stack passes through the junction joint and fills the storage member, the blocking member blocks the inside of the storage member and the outside of the storage member, thereby preventing odor leakage. .
Therefore, if the drain pipe storage structure of the present invention is used, a plurality of appliance drain pipes can be integrated and odor leakage from the storage member can be prevented.
In addition, siphon force is generated when the drainage from the watering device becomes full in the dredging pipe part, the drainage in the equipment drainage pipe is made into a siphon flow, merges at the junction joint, and sent into the drainage stack. In the siphon drainage system using such siphon force, the drainage pipe storage structure according to the present invention works favorably because one appliance is drained one by one.
Further, in the siphon drainage system, the flow rate of drainage during siphon drainage increases as the water head Hs (head) increases (the long pipe section). According to the drain pipe storage structure according to the first aspect, the length of the trough pipe portion can be optimized according to the flow rate required by the watering device.

A drainage pipe storage structure according to a second aspect of the present invention is characterized in that in the drainage pipe storage structure according to the first aspect , the outer surface of the closing member is in close contact with the inner surface of the storage member.

Next, the operation of the drain pipe storage structure according to claim 2 will be described.
Since the outer surface of the blocking member and the inner surface of the storage member are in close contact with each other, leakage of odor from the close contact surface is prevented.

A drainage pipe storage structure according to a third aspect of the present invention is characterized in that in the drainage pipe storage structure according to the first or second aspect , the closing member is made of an elastic body.

Next, the operation of the drain pipe storage structure according to claim 3 will be described.
Since the closing member is made of an elastic body, at least the adhesion between the inner surface of the insertion hole and the outer surface of the drain pipe can be further improved.

The drainage pipe storage structure of the present invention integrates a plurality of appliance drainage pipes, prevents leakage of odor from inside the storage member, and further reduces the length of the dredge pipe part according to the flow rate required by the watering device. Can be optimized.

[First Embodiment]
(Configuration) Next, a closing member and a drain pipe storage structure using the closing member will be described with reference to FIGS. FIG. 1 is a schematic view showing a part of a siphon drainage system in a high-rise apartment to which the drain pipe storage structure 10 according to the first embodiment is applied, and FIG. 2 is an enlarged partial sectional view of FIG. (A) is a top view of a closure member, and FIG.3 (B) is a BB cross section of FIG. 3 (A). An arrow H in the figure indicates the vertical direction.

Reference numeral 12 in FIG. 1 indicates a drainage stack that penetrates each floor of a high-rise apartment vertically (substantially in the vertical direction), reference numeral 14 indicates a watering device installed on each floor, and reference numeral 16 indicates a floor slab on each floor. . A plurality of instrument drain pipes 20 are independently connected to these watering instruments 14. The appliance drain pipe 20 includes a horizontal pulling pipe 22 that is installed on the floor slab 16 without any gradient and extends in a substantially horizontal direction, and a bend pipe that is bent into a substantially L shape with one end connected to the horizontal pulling pipe 22. 23 and a soot pipe 24 (soot pipe part) that is connected to the other end of the bend pipe 23 and extends downward in the direction of the arrow H. It is assumed that the horizontal pulling tube 22 does not merge on the floor slab 16.

  As shown in FIG. 1, the lower end side of the soot tube 24 is housed inside the medium diameter tube 30. The medium-diameter pipe 30 extends in the direction of arrow H, and the lower end thereof is fixed to one connecting portion of a substantially L-shaped junction joint 32. The other connecting portion of the junction joint 32 is connected to the drainage stack 12. The junction joint 32 joins the drainage flow from the vertical pipe 24 and sends it into the drainage stack 12. Further, a closing member 40 made of a substantially cylindrical elastic body (for example, rubber, urethane, etc.) is inserted into the upper end portion of the medium diameter tube 30 as shown in FIG.

  As shown in FIG. 3, the closing member 40 is provided in the main body portion 43, and a main body portion 43 whose outer peripheral surface is in close contact with the inner peripheral surface of the medium diameter tube 30 by being inserted into the inner diameter tube 30. The diameter of the main body 43 is larger than that of the main body 43, and an annular flange 44 that prevents the main body 43 from dropping into the medium-diameter pipe 30 and an inner peripheral surface of the main body 43 are inserted through the soot tube 24. It has an insertion hole 42 extending in the axial direction of the main body 24 that is in close contact with the outer peripheral surface of the soot tube 24.

  In this embodiment, the drainage stack 12 is a stainless steel pipe, and the instrument drainage pipe 20 is a flexible resin pipe made of polybutene. However, the material of each pipe need not be limited to this configuration. Any material can be used as long as it is a material of piping used in conventional construction piping.

Moreover, in this embodiment, since the siphon drainage system which drains the water in the instrument drainpipe 20 to the drainage stack 12 using the siphon force is used, the diameter of the instrument drainpipe 20 can generate the siphon force. Use a possible diameter. Also, in the siphon drainage system, the greater the head Hs (head) (the longer the soot pipe 24), the higher the flow rate of drainage during siphon drainage, so the length of the soot pipe 24 depends on the flow rate required by the watering device. It is preferable to optimize the thickness. In this optimization, for example, when a flow rate is required, such as in the case of stored water drainage in a bathtub or a washing machine, the length of the tub tube 24 is increased to ensure a sufficient flow rate, and the flow rate is not so high. If not, it means that the length of the tub tube 24 is shortened to reduce the member cost.
The detailed description of the siphon drainage system has been proposed by the applicant of the present patent, and the description thereof is omitted (Japanese Patent Laid-Open Nos. 2002-302977 and 2003-201727).

Further, if the soot tube 24 is previously processed into a predetermined dimension (a length corresponding to the flow rate required for the watering device 14) at the factory, it is inserted into the closing member 40 at the site to be a medium diameter tube. By storing in 30, the operation | work which measures the length required for the soot tube 24 on the spot and processes it into that length can be abbreviate | omitted, and work efficiency can be improved. In that case, as shown in FIG. 1, even if the lower end portion of the soot tube 24 is not connected to the junction joint 32 (for example, inserted into the connection portion of the junction joint 32), Since the lower end side is housed, drainage or the like does not leak out. Moreover, when the lower end part of the dredge pipe 24 is opened in the medium diameter pipe 30, it is possible to set an optimum water head Hs in each watering device (change the length of the dredge pipe 24), Further, since the soot pipe 24 is connected to the junction joint 32 and the drainage stack 12 through the medium diameter pipe 30, it is possible to rationalize by reducing the number of members.
In the present embodiment, as shown in FIG. 1, the lower end portion of the soot tube 24 is not connected (opened) to the junction joint 32, but it is not necessary to be limited to this configuration. It is also possible to adopt a configuration in which the lower end of the stub is connected to the junction joint 32.

(Operation) According to the drainage pipe storage structure 10 using the closing member 40 described above, since the plurality of soot tubes 24 are integrally supported by the closing member 40, the plurality of soot tubes 24 are integrated and integrated. And accommodated in the medium diameter tube 30. In addition, even if the odor from the drainage stack 12 passes through the junction joint 32 and fills the inside pipe 30, the closing member 40 closes the inside of the inside pipe 30 and the outside of the closing member 40. Odor leakage is prevented. Therefore, the plurality of soot tubes 24 can be integrated, and odor leakage from the inside of the medium diameter tube 30 can be prevented.

  In addition, the blockage of the medium diameter tube 30 by the blocking member 40 is specifically that the outer peripheral surface of the soot tube 24 and the inner peripheral surface of the insertion hole 42 are in close contact with each other and the inner peripheral surface of the medium diameter tube 30. It is made by the close contact with the outer peripheral surface of the closing member 40, and odor leakage from these close contact surfaces is prevented. Further, since the closing member 40 is made of an elastic body, the close contact between the inner peripheral surface of the insertion hole 42 and the outer peripheral surface of the soot tube 24 is further improved, and the inner peripheral surface of the medium diameter tube 30 and the outer peripheral surface of the closing member 40 are The adhesion is further improved.

  Further, in the present embodiment, siphon force is generated when the drainage from the watering device 14 becomes full in the soot pipe 24, and the drainage in the device drainage pipe 20 is made into a siphon flow. A siphon drainage system that uses a so-called siphon force that is joined and sent into the drainage stack 12 is used. In such a siphon drainage system that uses siphon force, the drainage pipe storage structure 10 using the closing member 40 is suitable for the drainage of one appliance. In this embodiment, the drainage pipe storage structure 10 using the closing member 40 is applied to the siphon drainage system. However, the present invention is not limited to this configuration, and the drainage pipe storage structure 10 may be applied to a normal drainage system. And

Without being limited to the configuration, the closing member may be a lid structure that covers the upper end portion of the medium-diameter pipe and a part of the outer peripheral surface. For example, an example of the closing member (closing member 50) using this lid structure will be described with reference to FIG. 4. The contact surface 51 (inner peripheral surface) is in close contact with the upper end of the medium diameter tube 30 and part of the outer peripheral surface. It has a main body part 53 and an insertion hole 52 provided in the main body part 53 and extending in the axial direction of the main body part 53 so that the inner peripheral surface is in close contact with the outer peripheral surface of the soot tube 24 when the soot tube 24 is inserted.
