Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage pipe joint used for connecting a plurality of horizontal branch pipes to a drainage stack.

[0002]

2. Description of the Related Art For example, the height of the core of a drain port provided on the rear surface of a wall-drain type toilet bowl is various, such as 100 mm, 120 mm, and 155 mm, even if it is standardized in Japan. Yes, adding foreign products will increase the variety. In addition, about the installation place of the toilet,
There are various cases, such as placing directly on the concrete slab S, laying the concrete slab S with anti-vibration rubber of various thicknesses, and further installing the concrete slab S on a wooden floor.

[0003] As described above, at the stage of installing a toilet, a drainage pipe joint (collective pipe joint) that has already been constructed has been completed.
At the stage of connecting the toilet to the toilet, the core height of the drain port of the toilet with respect to the core height of the receptacle of the pipe joint varies, and a horizontal branch pipe is provided for the core height of the various toilet drain ports. Pipes must be installed with a gradient in the downflow direction. However, if the horizontal branch pipe for connecting the two is manufactured to a predetermined size or shape by actual matching, the manufacturing cost increases, and it takes time for construction.

[0004] Conventionally, in order to solve this problem, an adapter provided with a receptacle is vertically adjusted with respect to the pipe joint body so as to be able to cope with various core heights of the toilet outlet. However, in this type of pipe joint, for example, when the toilet is placed directly on the concrete slab, when the adapter is slid downward to avoid a reverse slope, it hits the concrete slab and reaches a predetermined position. In some cases, it could not be lowered, and it was not possible to provide an appropriate gradient in the downflow direction.

Further, the pipe joint is divided into an upstream side and a downstream side,
There is provided a two-piece pipe joint configured to cut the upstream side to an appropriate length according to the site and connect it to the downstream side, but in the case of this pipe joint, once the cutting dimension is incorrect, it is connected to this. There is a problem that the drainage stack must be re-piped. In addition, in the case of this two-piece type pipe joint, since the packing fastening flange is provided at the upper part of the downstream joint, the position of the receiving port of the upstream joint becomes higher by that amount, so that it is placed directly on the concrete slab. There is a case where the horizontal branch pipe becomes higher in height than the drain port of the finished toilet and the slope becomes reverse. As a result, there is a problem that it is not possible to cope with the slab direct placing method.

SUMMARY OF THE INVENTION An object of the present invention is to provide a drainage pipe joint which can solve the problems of the conventional collective pipe joint.

[0007]

Therefore, a drainage pipe joint according to claim 1 has a plurality of receptacles for connecting horizontal branch pipes on a side of a main body. Wherein at least one of the plurality of receptacles is provided as a variable receptacle provided on an adapter plate provided separately from the main body, and the variable receptacle has a plurality of types of positions with respect to the adapter plate. And a structure in which the height of the variable receptacle relative to a fixed receptacle other than the variable receptacle can be arbitrarily changed by selecting an appropriate type of adapter plate and removably attaching it to the main body. It is characterized by.

According to the drainage pipe joint, by selecting an appropriate adapter plate at the construction site, the center height of the variable receptacle can be changed, for example, in accordance with the center height of the drain port of the toilet. it can. The change of the core height of the variable receptacle is realized by setting various aspects with respect to the position of the variable receptacle with respect to the adapter plate and selecting an appropriate one from among them. Since the position with respect to the part is constant, there is no problem as in the conventional slide-type receptacle.

Further, unlike the conventional two-piece type pipe joint, there is no need to cut the pipe fitting according to the dimensions at the site. Therefore, it is necessary to re-install the pipe joint itself as in the case where the conventional cutting dimension is incorrect. Absent.

[0010] In particular, according to the above configuration, since the center height of the variable receptacle can be freely changed at the construction site, for example, at the stage of connecting a toilet to a pipe joint, It can easily cope with an attempt to connect a toilet with a different specification (core height of the drainage outlet), such as redoing the installation of a drainage pipe joint or changing the shape of the horizontal branch pipe No need.

According to a second aspect of the present invention, there is provided a drainage pipe joint according to the first aspect, wherein another drainage port is provided so as to avoid a flow-down front of the variable receptacle. I do.

According to the drainage pipe joint, it is possible to prevent the drainage flowing through the variable receptacle from flowing back to another horizontal branch pipe. In recent years, as the piping space has been reduced, the body of the drainage joint has tended to be reduced in diameter, and as a result, for example, the drainage of the toilet bowl that has flowed into the joint has its momentum, There is a problem in that the wastewater flows into another horizontal branch pipe located therein, and sewage and waste are ejected from, for example, a drain trap of a washing machine.

[0013] In this respect, according to the configuration of the second aspect, since another receiving port and, consequently, another horizontal branch pipe are not piped in front of the flow-down direction, even if the main body is narrowed, the backflow as in the conventional case is not performed. No problem.

According to a third aspect of the present invention, there is provided the drainage collecting pipe joint according to the first aspect, wherein the core height of the variable receiving port with respect to the fixed receiving port can be changed within a range of 150 mm or less. It is characterized by the following.

According to the drainage pipe joint, it is possible to cope with the core height of almost all of the drainage ports set in the Western style toilets made in Japan and foreign countries. That is, if the core height of the receiving port can be changed within a maximum range of 150 mm, the operation effect according to the configuration of claim 1 can be obtained for almost all the core heights without unnecessarily increasing the size of the pipe joint. be able to.

According to a fourth aspect of the present invention, there is provided a drainage pipe joint having a receptacle for connecting a horizontal branch pipe at a side of the main body, wherein the receptacle is provided with the main body. A variable receptacle is provided on an adapter plate separately provided, and a plurality of types of variable receptacles are prepared with respect to the position with respect to the adapter plate. It is characterized in that the height of the center of the variable receptacle from the floor on which the toilet is installed can be arbitrarily changed within a maximum range of 180 mm.

According to the drainage pipe joint, claim 1 is provided.
It is possible to cope with the difference in the core height of the toilet drain port with respect to the drainage pipe joint having a wider form than in the case of the configuration described above. For example, if the position of the fixed receptacle is located relatively close to the height of the variable receptacle, it is sufficient to specify the center height adjustment range of the variable receptacle with reference to the core height of the fixed receptacle. However, when the fixed receptacle is greatly displaced in the height direction with respect to the variable receptacle, such as when the fixed receptacle is located on the lower floor across the concrete slab, the adjustable range of the variable receptacle is set based on the other receptacles. It is not appropriate to specify, and in this case, it is desirable to use the upper floor where the toilet is installed as a reference.

As described above, if the height of the center of the receptacle can be changed within a range of 180 mm at the maximum with respect to the floor surface on which the toilet is installed, almost all of the cores of the toilet outlet, regardless of whether they are made in Japan or abroad. Can respond to height.

According to a fifth aspect of the present invention, there is provided a drainage pipe joint according to the first or fourth aspect, wherein the adapter plate is attached to the main body by bolting, and a bolt insertion hole of the adapter plate is provided. Is characterized by having a vertically long slot that can adjust the vertical position of the adapter plate with respect to the main body.

According to the drainage pipe joint, claim 1 is provided.
Alternatively, in addition to the functions and effects according to the configuration described in 4, it is possible to cope with an unacceptable construction error.

According to a sixth aspect of the present invention, there is provided a drainage collecting pipe joint, wherein the variable receptacle according to the first, fourth, or fifth aspect is provided in a two-piece drainage collecting pipe joint having a main body portion divided into an upstream side and a downstream side. It is characterized by being applied.

According to the drainage pipe joint, for example, when installing on a stepped slab, or when providing a wooden floor of a predetermined height on a concrete slab and connecting a toilet bowl or the like installed on the wooden floor, etc. With respect to the two-piece drainage collecting pipe joint to be used, it is possible to cope with a change in the specification of the connecting device such as a toilet bowl (change in the height of the core) or a construction error.

The drainage collecting pipe joint according to claim 7 is the drainage collecting pipe joint according to claim 1 or 4 or 5, wherein the variable receiving port is prepared separately from the adapter plate. It is characterized in that a variable receptacle is selected and can be attached to the adapter plate.

According to the drainage pipe joint, the present invention can be applied to various connection forms.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 1 is a collective pipe joint for drainage according to the embodiment described below (hereinafter simply referred to as “pipe joint”).
1) shows a state in which the Western-style toilet 2 is connected to the drain stack 3 via the drain 1. In addition, in the figure, 3a shows the drainage stack on the upstream side, and 3b shows the drainage stack on the downstream side. S denotes a concrete slab, and approximately half of the pipe joint 1 on the downstream side is buried back in the concrete slab S and fixed in a predetermined state. The form of connection to the upper connection port 1a to which the upstream drainage stack 3a is connected and the lower connection port 1b to which the downstream drainage stack 3b is connected need not be particularly changed, and will not be described in detail.

The toilet 2 is installed on the upper surface of the concrete slab S via a vibration isolating rubber 5 having a thickness t. A drain port 2a is provided on the rear surface (the right side in the figure) of the toilet bowl 2, and one end of the horizontal branch pipe 4 is connected to the drain port 2a. The other end of the horizontal branch pipe 4 is connected to the variable receptacle 10 of the pipe joint 1.

The variable receptacle 10 is provided with an adapter plate 11
Are formed integrally. Variable receptacle 10 shown in FIG.
Is provided substantially at the center of the adapter plate 11 in the vertical direction. In the present embodiment, as shown in FIG. 2, in addition to the above, a total of three types are prepared, one in which the variable receptacle 10 is provided on the upper side of the adapter plate 11 and the other in which the variable receptacle 10 is provided on the lower side. Hereinafter, the variable receptacle 10 provided above the adapter plate 11 is referred to as
A, the variable receptacle 10 provided in the center of the adapter plate 11 in the up-down direction is “receptacle 10B”, and the variable receptacle 10 provided below the adapter plate 11 is “receptacle 1”.
0C ".

Each of the adapter plates 11 to 11 has the same configuration except that the setting positions of the variable receptacles 10 (10A, 10B, and 10C, the same applies hereinafter) are different from each other. It is configured to be detachably attached to an attachment seat 13a provided on the left side surface in the figure.

As shown in FIG. 3, a substantially oval opening 13b which is long in the vertical direction is formed in the center of the mounting seat 13a. FIG. 3 shows a state where the inside of the pipe joint body 13 is opened through the opening 13a. Screw holes 13c to 13c are formed at a total of four places, that is, the upper and lower ends and the left and right ends of the mounting seat 13b.
The adapter plate 11 is mounted at a fixed position on the mounting seat 13a by screwing the bolts 12 to 12 into the mounting seat 13a. The packing 11a is interposed between the adapter plate 11 and the mounting seat 13a,
Water leakage between the two is prevented. When the adapter plate 11 is mounted on the mounting seat 13a, the horizontal branch pipe 4 is connected to the pipe joint body 13 via the variable receptacle 10 and the opening 13b.
It is communicated inside.

On the other hand, a receiving port 14 for connecting another horizontal branch pipe is provided integrally on the side of the pipe joint body 13 in a direction perpendicular to the axis of the opening 13b. A screw portion 14a is formed at the tip of the fixed receiving port 14. Another horizontal branch pipe (not shown) is inserted into the inner peripheral side, and a so-called cap nut 14b is inserted into the screw portion 14a in a state where packing is interposed. Is tightened, another horizontal branch pipe is connected to the fixed receiving port 14.

As described above, the variable receiving port 10 and the fixed receiving port 14 are provided on the side of the pipe joint body 13, and both are provided in a positional relationship orthogonal to each other. Moreover,
On the side of the pipe joint body 13, no receiving port is provided on the downstream facing surface of the variable receiving port 10. That is, the fixed receiving port 14 is arranged at a position avoiding the facing surface of the variable receiving port 10.

Moreover, by arbitrarily selecting the variable receptacle 10A, 10B or 10C, the core height h of the variable receptacle 10 with respect to the fixed receptacle 14 can be changed in three stages. This change work is for bolts 12-12
Can be easily performed at the construction site.

At the tip of each of the variable receptacles 10A, 10B, 10C, a threaded portion 10a is formed similarly to the fixed receptacle 14, and the end of the lateral branch pipe 4 is inserted into the inner peripheral side of each of the variable receptacles 10A, 10B, 10C. The horizontal branch pipe 4 is connected to the variable receptacle 10 by tightening the cap nut 10b to the screw portion 10a in a state where the screw portion 10a is interposed (see FIG. 1).

According to the pipe joint 1 configured as described above,
Variable receptacles 10A, 10B, 10 provided at three different positions in the vertical direction with respect to the adapter plate 11, respectively.
C is arbitrarily selected according to the core height H (including the thickness t of the vibration-isolating rubber 5) of the drain port 2a of the toilet 2 to be connected from the upper surface of the concrete slab S. That is, as described above, the variable receptacle 10B is attached to the attachment seat 13a of the pipe joint body 13 in FIG. This variable receptacle 10
B is selected when the core height H of the drain port 2a of the toilet 2 is 120 mm.

The pipe joint 1 is constructed on a concrete slab S with reference to a positioning line 1c provided below the fixed receiving port 14. That is, the pipe joint 1 is fixed so that the positioning line 1c is aligned with the upper surface of the concrete slab S, so that the fixed receptacle 14 has a constant core height h0 with respect to the upper surface of the concrete slab S. Therefore, the center height of the variable receptacle 10 with respect to the upper surface of the concrete slab S is (h + h0).

In the case of this embodiment, as shown in FIG.
h0 = 110 mm, that is, the variable receiving port 10B is set at a core height of 110 mm from the upper surface of the concrete slab S. Therefore, a step of 10 mm (difference in core height) between the drain port 2a of the toilet bowl 2 and the variable receptacle 10B.
Is generated, whereby an appropriate drainage gradient can be given to the horizontal branch pipe 4.

Next, although not shown, it is assumed that the toilet 2 is directly installed on the upper surface of the concrete slab S without the intermediation of the vibration isolating rubber 5 (direct installation). The core height H is reduced by the thickness t of the vibration isolating rubber 5. For this reason, for example, the thickness t =
When a 20 mm one is used, H = 100 mm, and in this case, a drainage gradient cannot be given at the receiving port 10B.

Therefore, in the case of this direct installation, the receptacle 10C may be selected in place of the receptacle 10B. When the receiving port 10C is selected, the core height with respect to the upper surface of the concrete slab S is set to be h + h0 = 90 mm.

By selecting this receptacle 10C,
A step of 10 mm can be provided for the drain port 2a of the toilet bowl 2 placed directly, so that an appropriate gradient can be given to the horizontal branch pipe 4.

On the other hand, for example, assuming that the toilet 2 is set on a wooden floor laid at a height of 55 mm above the concrete slab S, in this case, the drain port of the toilet 2 2a, the height H of the core from the upper surface of the concrete slab S is 155 mm.
Alternatively, at the receiving port 10C, the horizontal branch pipe 4 cannot be connected because the step with respect to the core height H of the drain port 2a is too large.

Therefore, in this case, the receptacle 10A is selected. When the adapter plate 11 having the receiving port 10A is selected and mounted on the mounting seat 13a, the core height of the concrete slab S with respect to the upper surface is h + h0 = 145.
mm. By selecting the receptacle 10A, a drainage gradient of 10 mm can be ensured even when the toilet is installed on a floor 55 mm above the upper surface of the concrete slab S.

As described above, according to the pipe joint 1 of the present embodiment, at the stage of installing the toilet 2, the core height H is changed with respect to the already installed pipe joint 1, or Even if a construction error occurs, the horizontal branch pipe 4 can be connected while securing an appropriate drainage gradient by selecting three types of variable receptacles 10A to 10C at the construction site.

Further, according to the pipe joint 1 of the present embodiment, since the other receptacle 14 is not arranged on the opposite surface of the variable receptacle 10 to which the toilet bowl 2 is connected, it flows through the horizontal branch pipe 4. It is possible to prevent a problem that the drainage is directly discharged from the trap for the drainage of the washing machine via the other receiving port 14 as it is. In this regard, there is no particular problem if the diameter of the pipe joint body is sufficiently large,
As described above, it is particularly significant when the recent tendency to narrow the piping space is taken into consideration. Even if the diameter of the pipe joint body is reduced, the backflow phenomenon of drainage can be avoided.

Next, in the embodiment described above, the configuration in which the center height h of the variable receptacle 10 from the fixed receptacle 14 can be changed in three stages, ie, three types of variable receptacles 10A, 1
Although the case where 0B and 10C are prepared is illustrated, it is also possible to prepare more types of variable receptacles to develop a configuration that can correspond to the toilet bowl 2 having the drain port 2a with various core heights. It is possible.

FIG. 1 shows an example in which the variable receptacle 10 is of a short type having a length that does not penetrate the partition B of the toilet. However, the present invention is not limited to this. The same applies to a long type having a length penetrating the partition wall B.

Further, as shown in the example, the configuration is such that the core height of the variable receptacle 10 can be changed within a maximum range of 150 mm with respect to the fixed receptacle 14 as shown in FIG.
And the variable receptacle 10 is the fixed receptacle 1 as shown in FIG.
In the case where the height of the variable receptacle 10 is greatly deviated from the top to the bottom, the core height of the variable receptacle 10 can be changed within a maximum range of 180 mm based on the upper surface of the concrete slab S, that is, the installation surface of the toilet 2 Is desirable.

FIGS. 4 and 5 show construction examples in which the toilet bowl 2 is directly installed on the upper side of the stepped slab SD and the drainage pipe joints 20 and 30 are installed on the lower side. Since the concrete slab SD is stepped, the fixed receiving port 14 and the variable receiving port 10 are largely displaced vertically. FIG. 4 shows the pipe joint 20 in which the fixed receiving port 14 is located on the upper floor side of the concrete slab SD, and FIG. 5 shows the pipe joint 30 in which the fixed receiving port 14 is located on the lower floor side of the concrete slab SD.

In the case of the pipe joints 20 and 30 having such a configuration, the installation surface of the toilet 2, that is, the concrete slab SD
If the center height of the variable receptacle 10 can be changed within a range of up to 180 mm with respect to the upper surface of the upper stage side, the center height of almost all possible outlets for Japanese-style and foreign-made Western toilets Can be handled. In FIGS. 4 and 5, members that do not need to be changed are given the same reference numerals.

The screw hole 13 provided in the mounting seat 13a
The arrangement of c to 13c is not limited to the illustrated form,
For example, as shown in FIG. 6, the mounting seat 13a may be provided at four upper and lower corners, and at six or more locations including the center in the height direction.

Next, as disclosed in, for example, Japanese Patent Publication No. 5-38099, as one form of a collecting pipe joint, there is provided a horizontal branch pipe receiving port formed in a bent shape including an inclined portion. According to the collective pipe joint of this embodiment, the collision of the inflowed drainage with the inner wall of the pipe joint can be reduced, so that an excessive pressure fluctuation inside the pipe joint can be prevented, and the drainage noise can be reduced. However, according to the collecting pipe joint of this form, the lateral branch pipe receiving port is inclined,
When this port is constructed through the wall of the building,
When the relative position of the receptacle with respect to the wall surface changes, it is necessary to change the shape of the opening of the decorative plate for closing the through hole of the wall surface accordingly. There was a problem that it had to be manufactured in.

In this regard, the above-described collective pipe joints 1 and 2
According to Nos. 0 and 30, the variable receptacle 10 does not penetrate the partition wall B of the toilet as shown in FIG. P suffices, and as a result, it is possible to eliminate the time and labor required for the construction (the actual adjustment).

Next, in the embodiment described above, the adapter plate 1 with respect to the mounting seat 13a of the pipe joint body 13 is set.
Although the attachment position of 1 was fixed, for example, as shown in FIG. 7, bolt insertion holes 41 a to 41 a provided at the four corners of
It is good also as a structure which can adjust the position of an up-down direction.

According to this configuration, the variable receptacle 40 (40
A, 40B, and 40C) can be adjusted in the vertical direction within a certain range, so that it is possible to more precisely respond to a change in the core height H or a construction error.

If the adjustment margin of the adapter plate 11 in the vertical direction is set to at least 14 mm above and below the reference position, and preferably to about 20 mm as shown in FIG. 7, a normally occurring construction error is about ± 10 mm. Therefore, almost all construction errors can be dealt with.

The adapter plate 11 (41) and the variable receptacles 10A, 10B, 10C (40A, 40B, 4
0C) has been described as an example in which they are integrally formed, but they may be formed separately. The variable receptacle 50 shown in FIG. 8 is manufactured separately from the adapter plate 51, and the variable receptacle 50 is formed by screwing the male screw part 50 a provided on the variable receptacle 50 into the female screw part 51 a provided on the adapter plate 51. It can be attached to the plate 51. The adapter plate 51 has a female thread 51a
For example, three types of core heights are prepared, and accordingly, three types of core heights of the variable receptacle 50 (50A, 50A) are provided.
B, 50C).

The variable receptacle 50 shown in FIG. 8 is a straight-type receptacle of a cap nut connection type. If the adapter plate and the variable receptacle are configured separately, the present invention is not limited to this straight type, and can be applied to various other types of variable receptacles.

For example, the variable receptacle 60 shown in FIG.
It is an elbow type bent in a substantially L-shape, and is similarly attached by screwing the male screw portion 60a into the female screw portion 61a of the adapter plate 61. In the case of the elbow type variable receptacle 60, a horizontal branch pipe in any direction can be connected as shown in FIG. 10A shows a case where the variable receptacle 60 is turned rightward, FIG. 10B shows a case where it is directed upward, and FIG. 10C shows a case where it is directed leftward. If three types of core heights of the female screw portion 61a are set, the core height of the variable receptacle 60 can be changed to three types (60A, 60B, 60C),
Also, as shown in the drawing, through holes 62 through for fixing bolts provided in the four corners of the adapter plate 61 for the joint body.
Since the long holes 62 are formed vertically long, the variable receptacles 60A, 60B, and 60C can be adjusted vertically.

The variable receptacle 70 shown in FIG. 11 employs a one-touch packing connection system instead of the above-described cap nut connection system. An external thread 70a is formed in the variable receptacle 70, and the external receptacle 70a is screwed into a female thread 71a provided in the adapter plate 71, so that the variable receptacle 70 is attached at, for example, three positions with respect to the core height. A substantially cylindrical one-touch packing 72 is mounted on the inner peripheral surface of the variable receiving port 70, and the lateral branch pipe 4 is inserted into the inner peripheral side of the one-touch packing 72 so that the variable receiving port 70 is attached to the variable receiving port 70. Tube 4 is connected.

FIG. 12 shows an embodiment in which the variable receptacle 80 is provided integrally with the adapter plate 81. One-touch packing 82 is also provided on the inner peripheral surface of this variable receptacle 80.
Are mounted, and the horizontal branch pipe 4 is connected in the same form as the variable receptacle 70. As described above, the connection form is arbitrary even with the variable receptacle integrated with the adapter plate.

Next, FIGS. 13 and 14 show construction examples of various forms. The construction example shown in FIG. 13 shows a case in which a wooden floor M is provided on the upper side of the stepped slab SD, and the toilet bowl 2 installed on the wooden floor M is connected to the collecting pipe joint 90. In this case, a so-called two-piece type pipe joint whose trunk portion is divided into an upstream side and a downstream side is used as the collective pipe joint 90. This two-piece type pipe joint is conventionally known and will not be described in detail. However, by changing the position of the upstream joint 90A with respect to the downstream joint 90B, it is possible to cope with stepped slabs SD having various steps. .

The upstream joint 90A of the pipe joint 90 includes:
A one-touch packing connection type variable receptacle 91 is attached via an adapter plate 92, and the toilet bowl 2 is connected to the variable receptacle 91 via the horizontal branch pipe 4. The gradient of the horizontal branch pipe 4 is selected by selecting an appropriate variable receptacle 91A (or 91B, 91C) for the core height and mounting the same.
Alternatively, the position is adjusted to an appropriate value by adjusting the vertical position of the adapter plate 92. The downstream joint 90B is provided with a fixed-type receiving port 93. The variable receptacle according to the present invention can be applied to such a two-piece collecting pipe joint 90.

FIG. 14 shows an example of construction in which a wooden floor M is provided on a flat flat slab SF instead of the stepped slab SD, and the toilet bowl 2 installed on the wooden floor M is connected to the collecting pipe joint 95. I have. Also in this case, a so-called two-piece type pipe joint is used as the collective pipe joint 95. An adapter plate 96 is provided on the upstream joint 95A of the collective pipe joint 95.
A variable socket 97 of a cap nut connection type is attached via the. The center height of the variable receptacle 97 is selected appropriately in accordance with the center height H of the connection port 2a of the toilet bowl 2, and the vertical position of the adapter plate 96 gives the horizontal branch pipe 4 an appropriate gradient. It has been adjusted accordingly.

The downstream joint 95B is also provided with two fixed receiving ports 98, 98 of the cap nut connection type. One of the fixed receiving ports 98 is provided with a pipe between the wooden floor M and the concrete slab SF. Another horizontal branch pipe 4 'is connected.

It should be noted that the two-piece collecting pipe joint 90,

B, 95B in which the positional relationship in the height direction can be arbitrarily changed within a certain range, whereby a stepped slab SD having various steps or a wooden floor M having various heights is provided. It has a configuration that can be adapted to. However, regarding the connection form of the upstream joint and the downstream joint, various forms such as a screw-in type, a mechanical flange type, or a slip-on type are known in addition to the above-described fixed ring type, and the present invention is applied regardless of these connection types. It goes without saying that it is possible. The two-piece collecting pipe joint having the above features is provided with various types of variable receiving ports 91, 97 (4) according to the present invention.
