DESCRIPTION OF THE PREFERRED EMBODIMENTS The contents of the invention will be described below with reference to the drawings. FIG. 1 shows a schematic view of a joint which is a first embodiment according to the present invention. Further, FIG. 2 shows an enlarged schematic view of the full flow prevention part in the joint shown in FIG. The gathering standpipe 51 is provided with a standpipe side connecting portion 55 connected by the standpipe side opening portion 52, and the communicating side opening portion 53 at the other end of the standpipe side connecting portion 55 is provided with a communicating portion 56. . A temporary storage part 57 capable of temporarily storing drainage is provided at the lower part of the communication part 56, and the bottom part has two downward inclined parts 58 for facilitating the flow of the drainage toward the communication side opening 53. Further, the upper side surface 59 of the communication portion 56 is provided with a ventilation portion 61 for releasing the pressure in the communication portion 56 at the time of inflow of drainage, and the other upper side surface 59 is provided with one horizontal pulling pipe side connecting portion 70. . Further, the upper longitudinal side surface 60 having a larger side area than the upper side surface 59 has two horizontal pulling tube side connecting portions 70. The communication-side openings 53 are open at two places on the bottom of the communication portion 56, and in this embodiment, there are two connecting passages 54 that serve as drainage passages. In addition, the inside of the communication path 54 is provided with a full-flow prevention unit 65 for preventing the inside of the communication path 54 from being filled with drainage.

Next, this embodiment will be described based on the flow of drainage with reference to FIGS. When the drainage is discharged from the drainage equipment connected to the horizontal pipe 62, the drainage advances in the horizontal pipe 62 toward the communication portion 56. At this time, the horizontal pulling pipe 62 is connected to the two surfaces (the upper side surface 59 and the upper long side surface 6) of the communicating portion 56.
0), the horizontal drawing pipe 62 has a high degree of freedom in installation, and the degree of freedom in layout of drainage equipment is improved. Subsequently, when the drainage flows into the communication part 56, the air in the communication part 56 is appropriately discharged from the ventilation part 61, so that the smooth inflow is realized. The drainage that has entered the communication section 56 is properly collected in the lower temporary storage section 57, and enters the communication path 54 through the communication side opening 53 at the bottom and is finally guided to the collecting stand pipe 51. In addition, when there is a solid matter in the drainage, the downwardly inclined portion 58, which is an inclined shape portion of the temporary storage portion 57.
Is smoothly discharged to the communication-side opening 53. Particularly, in this embodiment, since there are a plurality of communication-side openings 53, the risk of clogging is very small. In this embodiment, the horizontal drawing tube 6
The three nominal diameters of 2 are both 50 mm, and the drainage collected in the temporary storage portion 57 is designed so as not to exceed the lower end of the horizontal pipe connecting portion 70. Therefore, no matter how the installation of the drainage equipment connected to the temporary storage unit 57 is changed,
By simply connecting the horizontal draw pipe 62 and the horizontal draw pipe side connection portion 70 to each other in an optimum state, the horizontal draw pipes 62 are not arranged so as to straddle each other, and each drainage equipment and the temporary storage part 57 are connected. The connection can be constructed without problems. Therefore, the installation space of the horizontal draw pipe 62 is not wasted,
It also saves space. Further, in the case of the present embodiment, the diameter is made smaller than that of the conventional horizontal drawing tube 62 of the toilet bowl, and the horizontal drawing tube diameter is the same as that of other devices, and there is no restriction on the connection point. Therefore, there is no possibility that the drainage flowing from the horizontal pipe 62 will flow back to the other horizontal pipes 62, and the hygiene of a plurality of devices is sufficiently ensured. Further, the temporary storage part 57 of this embodiment is made of hard vinyl chloride and made of resin. Therefore, at the time of arrangement such as installation on the gathering stand pipe 51, it is easy to construct lightly. Further, the communication-side opening 53 is provided at the bottom, so that the weight of the waste water accumulated in the temporary storage portion 57 when the waste water is discharged from the temporary storage portion 57 can effectively act as the energy for discharge. In addition, since solid substances such as dirt are less likely to remain in the temporary storage portion 57, hygiene can be improved. Further, as the full flow prevention unit of the present embodiment, in the present embodiment, a plurality of projections 63 in the middle of the communication path 54 and a flow change guide 64 for changing the flow of the plate-like drainage near the vertical pipe side opening 52 are provided. I am using. By arranging these differently shaped objects, even if a large amount of drainage flows into the vertical pipe side connection portion 55, the flow of drainage is disturbed and a flow that entrains air is created so that it does not become a full flow. Therefore, the siphon action does not occur, and the drainage equipment connected to the drainage equipment is not adversely affected by pulling water. Although a plurality of protrusions are used as the full flow prevention unit in this embodiment, the same effect can be obtained as long as it is arranged in the communication path and disturbs the flow of drainage.

Next, FIG. 3 shows a schematic view of a joint showing a second embodiment of the present invention. A side sectional view of the second embodiment is shown in FIG.
Shown in. The same or corresponding components as those of the joint according to the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. In this joint, as in the first embodiment, the communication portion 56 is connected to the collecting stand pipe 51 via the communication side opening portion 53 provided in the bottom portion. The communicating portion 56 of this embodiment has a stepped portion 8 at the top.
It has a box shape with 0, and is provided with four horizontal pulling tube side connecting portions 70 on the side surface of the step portion 80. Here there are three nominal diameters of 50
A mm horizontal pulling tube 62 is connected, and the other one is covered with a lid 81. Further, a ventilation part 61 is provided in the upper part, and a lower part of the communication part 56 is a temporary storage part 57, and a downward inclined part 58 is provided toward the communication side opening part 53. Further, the outer bottom portion of the temporary storage portion 57 is substantially horizontal. Therefore, in this embodiment, the vent 61 can effectively discharge the pressure generated in the communication part 56 at the time of drainage inflow, so that the drainage itself can smoothly flow into the collecting stand pipe 51. . Moreover, since the horizontal pipe 62 can be connected to any of the connecting portions 70, workability is improved. Further, since the horizontal drawing tube of the conventional toilet bowl has a diameter of 75 mm, it has a small diameter, and has the same horizontal drawing tube diameter as that of other devices, and there is no restriction on the connection location.
In addition, when a drainage equipment is newly added in this embodiment, the equipment can be easily added simply by removing the lid 81 and providing a new horizontal pipe 62. Therefore, there is no need to add a header as in the past. Further, even when solid matter is present in the drainage, the downwardly inclined portion 5 can be smoothly moved by gravity.
8 and it is possible to effectively use the self-weight of the waste water accumulated in the temporary storage portion as the energy of the discharge when the waste water is discharged from the temporary storage portion due to the vertical pipe side connection portion 55 provided at the bottom. I can. Next, the arrangement of joints in the housing complex of this embodiment will be described with reference to FIG. This apartment house has a common area such as an outer corridor 86
And a dwelling unit 85, which is a living part of an individual, and a partition wall 87
It is divided by. Usually, a not-shown entrance or the like is arranged on the partition wall 87. It is connected to the collective standpipe 51 provided in the common part 86 via the standpipe side connection part 55, and the bottom part of the temporary storage part 57 is placed on the joint installation surface 83 in the housing unit part 82. In this embodiment, since the bottom is horizontal, it is possible to stably install the temporary storage part 57 with respect to the joint installation surface 83 when installing the temporary storage part 57.
As a result, the horizontal pipe connecting portions 70 can also be arranged in an orderly manner, which improves the workability. Further, the space where the joint is installed, that is, the floor pocket 84, can keep the height low because the diameter of the horizontal pipe 62 is made small, and thus the actual operating space 88 of the housing unit 85 can be expanded. It will be possible.

Next, FIG. 5 is a schematic view of a joint showing a third embodiment according to the present invention, and FIG. 6 is a side sectional view. See also FIG.
8 is a front view of the vertical pipe side opening viewed from the side of the vertical pipe, FIG.
An enlarged schematic view of the legs in this embodiment is shown in FIG. The same or corresponding components as those of the joint according to the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The configuration of this embodiment will be described with reference to FIGS. The joint of the third embodiment is connected to the collecting stand pipe 51 via the stand pipe side connecting portion 55 and is arranged on the joint setting surface 83. Further, the communication side opening 53 of the vertical pipe side connection portion 55 is provided on the side surface part which is separated from the bottom part to some extent, and the drainage W is left to some extent on the substantially horizontal bottom part of the temporary storage part, that is, the installation surface 200. Has become. The bottom part has four leg portions 101 to be described later,
A temporary storage part 57 for storing the drainage from the horizontal pipe 62;

00 has a ventilation part 61 formed of a ventilation pipe having a rectangular cross section. (The ventilation part 61 is omitted in FIG. 6.) Therefore, in this embodiment, since the drainage flows in from the convex portion 100 at the upper part of the temporary storage part 57, the drainage is smoother than that flowing in through the bend of the elbow shape. As a result, a large amount of drainage can be achieved and the horizontal pipe 62 can be easily connected. Further, since the shape is different from that of the temporary storage part 57, it is easy to design the structure so as to be easily connected to the horizontal draw pipe 62. Further, when connecting the horizontal draw pipe 62 to the horizontal draw pipe side connection portion 70, since the horizontal draw pipes are on the same surface, a plurality of horizontal draw pipe connections can be performed in the same posture, which effectively contributes to shortening the pipe during construction. . In addition, workability is improved because it is only necessary to check one side during maintenance such as water leak check. Further, even when the temporary storage section 57 is clogged by dirt or the like from the inspection port, it is possible to perform cleaning, which makes maintenance and management very easy. In particular, since the vertical pipe side connection portion 55 is provided at a certain distance from the bottom portion as in this embodiment, it is possible to pick up something (Z in the drawing) from the inspection port even if something (Z in the figure) is accidentally flown into the horizontal pipe. Becomes Further, as shown in FIG. 7, a plate-like drainage inflow prevention portion 105 projecting into the collecting stand pipe 51 is provided above the stand pipe side opening 52 of the stand pipe side connection portion 55.

Therefore, since the horizontal draw pipe is arranged in the vertical direction, the drainage from the horizontal draw pipe arranged below does not flow backward to the horizontal draw pipe installed above. Furthermore, if the drainage is arranged so as to be stored below the horizontal pipe connecting portion at the bottom, further sanitaryness of drainage is maintained. Also, especially the communication part 5
If the ventilation part 61 is provided in the upper part of 6, the drainage performance can be further improved. In the present embodiment, the communication portion is arranged in the common portion so that it can be seen, for the sake of clarity. However, by surrounding it with a pipe space or the like, designability and tampering prevention can be dealt with.

FIG. 10 is a schematic view of a joint system showing a fifth embodiment according to the present invention. FIG. 11 shows an enlarged schematic view of a joint portion (horizontal cross section) of the gathering stand pipe portion and the horizontal draw pipe in the fifth embodiment. The same or corresponding components as those of the joint according to the second embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The joint system of the fifth embodiment is a collective standpipe 5
1 has a vertical pipe side connection portion 55 provided with a flange portion 142 for connection with 1, and a flush toilet 141 and a bathtub 14
0 is a joint system including a communication part 56 that communicates with two horizontal pipes 62 that are individually connected, and the horizontal pipe 62 that is connected to the flush toilet 141 and the bathtub 14
The horizontal drawing tube 62 connected to 0 has the same nominal diameter.
Further, since the communication portion 56 has a bottom portion (indicated by diagonal lines in FIG. 11) that is inclined with respect to the collecting pipe 51, the drainage flowing into the communicating portion smoothly flows into the collecting pipe.
Therefore, since the horizontal pipe from the toilet bowl 141 and the horizontal pipe from the bathtub 140 can be connected to the communication portion 56 without distinguishing the devices, the construction time can be simplified and the degree of freedom of layout of the drainage equipment can be improved. Will increase. Nominal diameter 50
Since the connection is made in mm, the space in which the horizontal pipe is arranged can be made small, and the housing unit can be substantially expanded. Further, in this embodiment, the toilet bowl is particularly connected, and when backflow occurs, filth may be considered in addition to drainage. Therefore, the effect of the present embodiment of preventing the backflow is enormous. Further, in this embodiment, the connection to the collecting stand pipe was made by the flange portion, but of course, the use of other means does not change the essential effect.

FIG. 12 is a schematic view of a collecting stand pipe joint showing a sixth embodiment according to the present invention. FIG. 13 is a plan cross-sectional view of the joint portion of the collective vertical pipe joint in the sixth embodiment.
The same or corresponding components as those of the joint according to the fifth embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The collective vertical pipe joint of the sixth embodiment is provided with a connecting portion 150 with other collective vertical pipe joints at the top and bottom, and the pipe portion 1 communicating the connecting portion 150.

The expanded diameter portion 152 of this embodiment has a curved portion except for the side to which the horizontal draw pipe is connected, and the bottom portion of the expanded diameter portion has a slight slope in the direction of drainage flow. Therefore,
There is no need for a temporary storage part because drainage flows directly into the expanded part of the collecting stand pipe joint, and since drainage is discharged directly into the collecting stand pipe, there is no risk of backflow to the horizontal draw pipe. Moreover, the workability is very good because the construction is completed by the assembly of the assembly standpipe. In addition, better drainage can be obtained by providing a drainage guide inside the pipe section so that the central axis of the drainage flowing inside the pipe section has a ventilation section.

Next, FIG. 14 shows an explanatory view of piping seen from the upper surface of the whole experimental apparatus of the experiment for verifying the conventional technique. This is an experiment for verifying a defect due to drainage conditions when a plurality of horizontal drawing pipes 62 having a nominal diameter of 50 mm are joined to a conventional drainage header 180. Assembly standpipe 51
, Two conventional drainage headers are connected and connected via a joint (not shown). Each drainage header 180 has two horizontal pipe connection portions 190 open, and
From the side, a bathtub 140, a flush toilet 141, and a washing machine pan 170 are connected to each other through a horizontal pipe 62. It should be noted that the end portion of the lateral pipe connecting portion 190 is sealed without being connected to anything. Each of the horizontal draw pipes 62 is arranged as shown in the drawing, and A is 3 for each dimension.
m, B is 1.7 m, C is 2.7 m, D is 1.5 m, E is 2 m, F is 1 m, and G is 1 m. The horizontal drawing tube 62 has a nominal diameter of 50 mm, and the actual inner diameter 52
mm tube is used. The flush toilet 141 is a direct water pressure toilet, and the flush water amount, that is, the drainage amount is 8 L. Further, the drainage from the bathtub 140 was performed by collecting 200 L and pulling out a plug at the bottom of the bathtub (not shown). Next, the situation inside the pipe when water is actually drained from each drainage equipment will be described. When drainage is made to flow from the toilet bowl 141 only, the waste proceeds toward the collecting stand pipe and is discharged, but the drainage flows backward in the drain header 180. In addition, when draining from the toilet bowl 141 immediately after draining from the bathtub 140,
The drainage from 40 flows backward in the drainage header 180 and the toilet 1
Backflow has occurred in the horizontal draw tube 62 to which 41 is connected. However, after that, the drainage from the toilet bowl 141 was able to be smoothly discharged by flowing in the downstream direction. From the above experiment, if the toilet is installed near the drain header, that is, if the horizontal pipe connected to the toilet has no bend and the distance is short,
It was confirmed that the drainage water from the bathtub may flow back to the toilet bowl side, affecting the toilet bowl discharge performance. Therefore,
It has been confirmed that the configuration in which the backflow does not flow back to the other horizontal draw pipes as in each of the embodiments shown here is particularly effective when the diameter of the horizontal draw pipe is smaller than the conventional one.
