Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drainage pipe structure for connecting a toilet bowl.
[0002]
[Prior art]
Drainage pipe systems used in multi-storey buildings such as apartment buildings are constructed by installing drainage collection pipes corresponding to each floor with respect to standing main pipes that run vertically through each floor. A lateral branch pipe for each floor is connected via the pipe.
As shown in FIGS. 5 and 6, this type of drainage collecting pipe 100 is provided with a plurality of horizontal pipe joint portions 103 and 104 so that a plurality of side branch pipes 101 and 102 can be connected. There is something.
[0003]
For example, in the drainage collecting pipe 100 shown in FIG. 5, the two pipe joint portions 103 and 104 are provided in opposite directions (in a back-to-back manner) to form a flat single letter shape.
Therefore, naturally, when the side branch pipes 101 and 102 are connected to the pipe joint portions 103 and 104, respectively, the connection directions of the side branch pipes 101 and 102 are opposite to each other, and the pipe axes thereof are coaxial or It becomes a parallel state.
On the other hand, in the drainage collecting pipe 100 shown in FIG. 6, the two pipe joint portions 103 and 104 have a planar L shape.
[0004]
In such an L-shaped drainage collecting pipe 100 as well, the lateral branch pipes 101 and 102 connected to the pipe joint portions 103 and 104 are relatively opposite to each other in the same manner as in the single-letter type drainage collecting pipe 100 described above. In order to perform piping so as to be in a parallel state, an elbow 105 of 90 ° is provided for one of the pipe joint portions 104, and then the side branch pipe 102 is connected to the tip of this elbow 105.
[0005]
[Problems to be solved by the invention]
When the toilet drainage is drained using the one-letter type drainage collecting pipe 100 as shown in FIG. 5, the side branch pipe 101 connected to one of the pipe joint portions (referred to as the reference numeral 103 now) is connected to the toilet bowl. The side branch pipe 102 connected to the other pipe joint portion (and hence the reference numeral 104) is connected to the bath 107 or the like.
However, when the toilet drainage flows into the drainage collecting pipe 100 from the lateral branch pipe 101 on the toilet 106 side via the pipe joint portion 103 in this way, the toilet drainage surpasses the drainage collecting pipe 100 with a momentum, There was a case where the other pipe joint portion 104 would flow backward to the side branch pipe 102 connected to the bath 107 or the like.
[0006]
On the other hand, in the case where the toilet drainage is drained using the L-shaped drainage collecting pipe 100 and the elbow 105 as shown in FIG. The side branch pipe 101 to be connected is connected to the toilet 106, and the side branch pipe 102 to be connected via the elbow 105 provided at the other pipe joint portion (therefore, the reference numeral 104) is connected to, for example, a bath 107 or the like. It will be.
In this way, the drainage that has once flowed into the drainage collecting pipe 100 from the side branch pipe 101 on the toilet 106 side via the pipe joint 103 is transferred to the other side branch via the elbow 105 from the other pipe joint 104. It did not flow back to the tube 102 and was effective as a countermeasure against the backflow of toilet drainage as described above.
[0007]
However, in this piping configuration, the elbow 105 is attached, so that the space width W required for piping is inevitably too wide.
That is, this piping form requires a large pipe space on the building side.
For this reason, there is a problem that the effective floor area of the building is lost and this piping form cannot be adopted in the existing building (pipe space).
The present invention has been made in view of the above circumstances, and as a piping member such as a drainage collecting pipe for connecting a side branch pipe for a toilet and a side branch pipe for a bath or the like, It is an object of the present invention to provide a drainage pipe structure for connecting a toilet bowl that can prevent backflow to the branch pipes and that can accommodate the pipe space required for these pipes in a compact manner.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show a first embodiment of a piping member 1 according to the present invention.
This piping member 1 is, for example, a portion corresponding to each floor with respect to the standing main pipe when a standing main pipe (not shown) is piped vertically through each floor in a multi-storey building such as an apartment house. It is installed.
Therefore, an upper joint portion 3 and a lower joint portion 4 are provided at the upper end portion and the lower end portion of the pipe body 2 that forms the core of the piping member 1 for connection to the vertical main pipe longitudinal pipe. .
[0014]
In addition, although the upper joint part 3 of the example is a receptacle (socket or mechanical) type and the lower joint part 4 is an insertion (straight pipe) type, these may be other types such as a flange joint type.
A plurality (two in the illustrated example) of pipe joint portions 6 and 7 are provided on the side surface portion of the pipe body 2.
The pipe joint portions 6 and 7 in the figure are all of the receptacle (socket or mechanical) type, but may be other types such as a flange joint type and an inlet (straight pipe) type.
[0015]
These pipe joint portions 6 and 7 are oriented sideways so that the lateral branch pipes 101 and 102 can be connected. One of the lateral branch pipes 101 is connected to the toilet 106.
That is, the pipe joint portion 6 that connects the side branch pipe 101 connected to the toilet bowl 106 is used for connecting the toilet bowl 106.
The pipe joint portion 6 used for connecting the toilet 106 is positioned so as to protrude on the front side (upper side in FIG. 1) with respect to the pipe body 2.
[0016]
On the other hand, the other pipe joint portion 7 is provided at an end thereof via an elbow 8 protruding from the pipe body 2, and the direction of the pipe axis from which the elbow 8 protrudes from the pipe body 2 is The pipe axis of the pipe joint 6 for connecting the toilet 106 intersects the plane.
In the first embodiment, the elbow 8 is bent 90 ° backward (downward in FIG. 1) with respect to the tube body 2.
For this reason, if the side branch pipe 102 is connected to the pipe joint portion 7 provided at the tip of the elbow 8, and the side branch pipe 101 is connected to the pipe joint portion 6 without the elbow, these The lateral branch pipes 101 and 102 are in a state opposite to each other and have their pipe axes parallel to each other.
[0017]
The lateral branch pipe 102 connected via the pipe joint portion 7 provided at the end of the elbow 8 is connected to, for example, a bath 107 or the like.
The pipe body 2 and the elbow 8 and the pipe joint portion 7 provided at the tip of the elbow 8 are integrally formed with each other.
Accordingly, the piping member 1 according to the first embodiment has a compact space width W required for piping.
In addition, in the pipe body 2 of the first embodiment, the swirl vane 12 for efficiently flowing the drainage down to the vertical main pipe (not shown) (in FIG. 2, the swirl vane 12 is provided so that it appears on the outer peripheral surface. (Shown as a molding recess 13).
[0018]
In the piping member 1 having such a configuration, the side branch pipe 101 connected to the pipe joint portion 6 (for connecting the toilet bowl 106) provided without an elbow on the front side of the pipe body 2 as described above is connected to the toilet bowl 106. Further, the lateral branch pipe 102 connected from the pipe body 2 to the pipe joint portion 7 provided via the elbow 8 is connected to, for example, a bath 107 or the like.
In this case, it is possible to prevent the toilet drainage from once flowing into the pipe body 2 from the side branch pipe 101 and then backflowing from the other pipe joint portion 7 to the side branch pipe 102 via the elbow 8. .
[0019]
FIG. 3 shows a second embodiment of the piping member 1 according to the present invention.

The pipe joint portion 15 does not go through an elbow and protrudes in a straight tube shape with respect to the pipe body 2.
Therefore, it is preferable that the lateral branch pipe 111 connected to the pipe joint portion 15 is connected to the washing machine 110 or the like, for example.
[0020]
This is because if the side branch pipe 111 connected to the pipe joint portion 15 is temporarily connected to the toilet bowl 106, the toilet drainage flowing into the pipe main body 2 from the side branch pipe 111 is directly arranged symmetrically. This is because the gas flows backward to the pipe joint portion 7 beyond that.
In other words, in the piping member 1 of the second embodiment, either one of the pipe joint portions 6 and 7 can be used for connecting the toilet 106.
