Description

  The present invention relates to a drain pipe facility for an apartment house.

  Conventionally, drainage pipes in apartment buildings such as high-rise apartments have been drained upright from the upper floor to the lower floor through the private section of each dwelling unit, and the kitchen sink and toilet installed in the private section of each floor. A configuration in which a so-called watering device (drainage device) such as a toilet bowl or a bathroom tub is connected to a collecting pipe joint interposed in a drainage stack, and the drainage of various drainage devices is joined to the drainage stack and flowed down. It was general.

By the way, in recent years, as a house intended for long-term use, an SI house with increased layout variability in the exclusive section and durability of the skeleton part has attracted attention.
As a drainage pipe facility suitable for SI housing, for example, in Patent Document 1 relating to the present applicant, a first drainage standpipe is piped on the shared passage side facing the north side of the exclusive part of each dwelling unit, A drainage pipe facility is disclosed in which a second drainage stand pipe is provided on the opposite side of the balcony on the south side so that drainage devices can be dispersed and connected to the closer of the drainage standpipe. According to this drain pipe facility, it is possible to easily cope with a large layout change in the exclusive part that moves the kitchen sink to the sunny balcony side.
Further, Patent Document 2 related to the present applicant discloses a drain pipe facility suitable for an SI house intended for long-term use by improving the ease of maintenance such as renewal and cleaning. In this drainage pipe facility, a so-called drainage header system is adopted for the collecting pipe joint, so that the horizontal branch pipe receptacles of the header joint are made to correspond one-to-one with each drainage device in the exclusive part. As a result, for example, the cleaning nozzle can be surely guided from the cleaning port of the header joint disposed on the shared passage side to the target drainage device, so that cleaning is easy, and only the necessary part of the side branch pipe is Can be updated.

JP 2000-328618 A JP 2005-146525 A

  The conventional drainage pipes disclosed in Patent Documents 1 and 2 include a toilet urinal, a kitchen sink, a bathroom drainage port, etc., although they are preferably improved for SI houses for long-term use. It is configured to merge the drainage of multiple drainage equipment into a drainage stand system (drainage standpipe and collecting pipe joint interposed in the drainage standpipe), especially bathroom drainage containing a lot of oil, oil and food waste Due to kitchen wastewater containing a large amount of solids, dirt may adhere to the drainage stack, making it difficult for the drainage to flow, and thus causing keratinization and clogging of piping. Therefore, it was necessary to renew the drainage stand system during the long-term use of the house. When the drainage stand system is renewed, all drainage equipment connected to the drainage stand system cannot be used during the renewal work period. In particular, the inability to use the toilet imposes great inconvenience on the residents. In order to eliminate this inconvenience, for example, in the drain pipe facility described in Patent Document 1, it is conceivable to reconnect the toilet toilet to another drain stack. However, although the period when it cannot be used can be shortened, there is still a problem that the toilet cannot be used during the connection work.

  The present invention has been made in order to solve the above-described problem, and has a drainage stand by adopting a piping configuration that can make a drainage standpipe system connected to a toilet urinal longer usable. The purpose of this study was to provide drainage pipe facilities for apartment buildings where toilets could hardly be used due to the renewal of the pipe system.

The present invention takes the following means as means for solving the above problems.
First, the first invention is a multi-story drainage pipe facility having drainage devices such as a toilet, a kitchen sink, a bathroom, a washing machine, and a wash basin, and the multi-story building penetrates the multi-story floor. Drainage pipes connected to the drainage standpipe system that are separated from the urinals of the dwelling units at each level and drainage equipment other than the toilet bowls. The standpipe system is dedicated to the toilet, and is piped separately to the private part of the dwelling unit or to the balcony side opposite to the common part corridor, and to the drainage equipment other than the toilet The drainage standpipe system is characterized in that the drainage standpipe system is piped on the shared hallway side or on the balcony side opposite to the shared hallway side.
According to the first invention, since the toilet and the drainage devices other than the toilet are separated and connected to the drainage stand system, the drainage stand system dedicated to the toilet has a high flow rate and a relatively oil content. Only a small amount of sewage in the toilet bowl flows, and wastewater with relatively high oil content such as kitchen drainage and bathroom drainage does not flow. Therefore, the dedicated drainage stand system to which the toilet is connected can have a long service life so that dirt does not easily adhere to the inside of the pipe and renewal work is not required during use of the house. As a result, it is possible to eliminate the possibility that the toilet cannot be used for renewal work. In addition, the drainage stand system to which drainage devices other than toilets are connected is piped to the shared part corridor side or the balcony side opposite to the shared part corridor side, and is not piped to the exclusive part. The variability can also be improved and can be preferably applied to SI houses.

A second invention is a drainage pipe facility for a multi-story residential building having drainage devices such as a toilet, a kitchen sink, a bathroom, a washing machine, and a wash basin. More than the drainage standpipe system is piped, and the toilet and kitchen sink of each level dwelling unit are individually piped as a dedicated drainage standpipe system, and drainage equipment other than the toilet and kitchen sink is provided. The other drainage standpipe system to be connected is piped to the shared hallway side or the balcony side opposite to the shared hallway side.
According to 2nd invention, the toilet bowl of the dwelling unit of each hierarchy is made into the exclusive drainage system. Due to the fact that the toilet drainage with a high flow rate and relatively low oil content is a dedicated drainage system, the dedicated drainage stand system to which the toilet is connected is less likely to get dirty inside the pipes, and it is difficult to It is possible to extend the service life so that renewal work is not required. As a result, it is possible to eliminate the possibility that the toilet cannot be used for renewal work.
The kitchen sink is also a dedicated drainage system, and kitchen drainage that contains a relatively large amount of oil and solids and easily clogs or deteriorates the drainage stand system is separated from the drainage of other drainage equipment. Therefore, the drainage stand system to which other drainage devices other than the toilet bowl and kitchen sink are connected has a longer service life, and the frequency with which other drainage devices cannot be used due to the renewal of the drainage stand system is reduced.

A third invention is the above-described second invention, wherein as the dedicated drainage stand system to which the kitchen sink is connected, the private part in the dwelling unit or the shared part corridor side or the balcony side opposite to the shared part corridor side The two systems are previously piped, and the kitchen sink is connected to one of the two dedicated drainage stack systems, and the other is used as a spare so that the connection can be changed.
According to the third invention, even when one dedicated drainage stand system cannot be used, the kitchen sink can be used by reconnecting the kitchen sink to the spare drainage stand system. The period when it cannot be used can be shortened to a short time during the connection change work.

According to a fourth aspect of the present invention, in any one of the first to third aspects of the present invention, a dedicated drainage stand system to which the toilet or kitchen sink is connected is a drainage standpipe piped to each level and the drainage standpipe. The toilet bowl or kitchen sink is connected to the vertical pipe joint, and the drainage vertical pipe or the vertical pipe joint is provided with a cleaning port. It is characterized by.
According to the fourth aspect of the present invention, since the vertical pipe joint is provided with the cleaning port, the drainage standpipe system and the side branch pipe that is piped between the drainage standpipe system and the toilet or the kitchen sink can be easily provided. It can be washed, and the service life of these drainage stand systems and side branch pipes can be further extended.

In a fifth aspect of the present invention, in any one of the first to fourth aspects, the drainage standpipe system other than the dedicated drainage standpipe system to which the toilet bowl or the kitchen sink is connected is drainage piped to each level. It consists of a standpipe and a standpipe joint disposed between the drainage standpipe, and other drainage devices other than the toilet bowl or kitchen sink are connected to the standpipe joint via a header joint with a cleaning port. It is characterized by that.
According to the fifth aspect of the present invention, since the other drainage devices that are not connected to the dedicated drainage stand system are each connected independently to the receiving port of the header joint with the cleaning port, each drainage device and the header joint In the cleaning of the side branch pipes arranged between the two, the target side branch pipe can be easily cleaned. Further, the drainage stand system can be easily cleaned using the cleaning port provided in the header joint, and the service life can be further increased.

  According to the drainage pipe facility of an apartment house of the present invention, it can be used for a long period of time so that it is almost unnecessary to update the standpipe system connected to the toilet urinal. It is possible to eliminate almost nothing that cannot be used.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 shows one dwelling unit J provided with a drain pipe facility H1 according to the first embodiment of the present invention. This dwelling unit J is a dwelling unit consisting of multiple floors such as apartments, and a plurality of dwelling units J to J along the corridor R shared by the residents of each dwelling unit J provided on each floor of the dwelling unit. They are arranged side by side. A balcony B (veranda) is provided on the opposite side of the corridor R across the exclusive part S of each dwelling unit J. In this embodiment, the case where the corridor R is located on the north side and the balcony B is located on the south side with respect to the exclusive part S of the dwelling unit J is illustrated. Therefore, in FIG. 1, the lower side is the north side, and the upper side is the south side.
In the exclusive part S of each dwelling unit J, the entrance 1, the three first to third living rooms 2 to 4, the bathroom 5, the washroom 6, the kitchen 7, the living room 8, and the toilet 11 are laid out as illustrated.

The first pipe space 40 is provided adjacent to the exclusive part S in the shared part on the corridor R side as viewed from the exclusive part S (corresponding to the “shared part corridor side” of the present invention). The first pipe space 40 is provided facing the corridor R, and is a common drainage connected to a drainage stand system 42 dedicated to a toilet, a drainage stand system 30 dedicated to a kitchen sink, and a plurality of drainage devices. Three drainage standpipe systems are connected to the standpipe system 17.
The drainage standpipe system 42 dedicated to the toilet is piped through from the upper floor to the lower floor of the apartment house, and the drainage standpipe 44 piped to each level and the drainage standpipe at a height below the floor. The toilet 11 a of the toilet 11 is connected to a horizontal branch pipe receiving port 46 a provided around the trunk of the vertical pipe joint 46 via a horizontal branch pipe 48. Around the trunk of the vertical pipe joint 46, a cleaning port 46b is provided on the side of the corridor R opposite to the side branch pipe receiving port 46a. By inserting a cleaning nozzle from the cleaning port 46b, the side branch pipe 48 and the drainage stack system 42 can be easily cleaned. The cleaning port 46b is provided with a lid that can be airtight and watertight.
The drainage standpipe system 30 dedicated to the kitchen sink is composed of a drainage standpipe 32 piped to each level and a standpipe joint 34 interposed between the drainage standpipe 32 at a height below the floor. It runs from the upper floor to the lower floor of the apartment building. The vertical pipe joint 34 is provided with one side branch pipe receiving port 34 a around its trunk, and the kitchen sink 7 a with a disposer of the kitchen 7 is connected through a side branch pipe 36. Around the trunk of the vertical pipe joint 34, a cleaning port 34b is provided on the side of the corridor R opposite to the side branch pipe receiving port 34a. By inserting a cleaning nozzle from the cleaning port 34b, the horizontal branch pipe 36 and the drainage stack system 30 can be easily cleaned. The cleaning port 34b is provided with a lid that can be airtight and watertight.

The common drainage stand system 17 is composed of a drainage standpipe 15 piped to each level and a standpipe joint 13 interposed between the drainage standpipe 15 at a height below the floor. It runs through the house from the upper floor to the lower floor. As shown well in FIG. 2, a mounting seat 13a is provided around the trunk portion of the vertical pipe joint 13, and a header joint having three receiving ports 81 to 83 (removable from the vertical pipe joint body). The adapter type horizontal branch pipe receiving port 80 is attached. An attachment flange 80d is provided at the base of the header joint 80, and the attachment flange 80d is abutted against the attachment seat 13a and fixed with bolts, so that the header joint 80 is attached in a state of protruding sideways. Yes. Various drainage devices for miscellaneous drainage other than the toilet 11a and the kitchen sink 7a are connected one-to-one to the lateral branch pipe receptacles 81 to 83 of the header joint 80. That is, the drainage appliances in the bathroom 5 (the bathtub drain 5a and the wash basin drain 5b) pass through the drainage branch pipe 70, and the washbasin drainage outlet 6b in the washroom 6 passes through the drainage lateral branch pipe 69. The washing machine drain port 6a of the station 6 is connected to the horizontal branch pipe receiving ports 81 to 83 of the header joint via the horizontal branch pipe 68, and is connected to the drainage standpipe system 17. On the upper surface of the header joint 80, cleaning ports 81b, 82b, and 83b for cleaning the pipes are provided corresponding to the receiving ports 81 to 83, respectively. The cleaning nozzles 81b, 82b, 83b can be easily cleaned by inserting a cleaning nozzle into the target side branch pipes 68, 69, 70. Further, from the cleaning port 81b closest to the flange portion 80d, the cleaning nozzle can be easily inserted into the vertical pipe joint 13 and the drainage vertical pipe system 17 can be cleaned. Each of the cleaning openings 81b, 82b, 83b can be sealed airtight and watertight by the lids 81c, 82c, 83c.
In FIG. 2, the inside is shown through a receiving port 13 c to which a drainage stack on the upstream side of the standpipe joint 13 is connected. Inside the vertical pipe joint 13, there is provided a swivel guide 13 d that protrudes inward from the side of the horizontal branch pipe drainage flowing into the vertical pipe joint 13 through the header joint 80 like a ridge. The swivel guide 13a is tilted toward the inside of the pipe and is slanted to the left as viewed from the inside of the pipe. The swivel guide 13a has a shape capable of turning the drainage of the vertical pipe to the left. In addition, a pair of swirl vanes 13e and 13e are provided inside the vertical pipe joint 13 so as to project inward of the pipe below the inlet of the side branch pipe drainage. The swirl vanes 13e and 13e are inclined downwardly to the left when viewed from the inside of the pipe, and have a shape capable of turning the drainage of the vertical pipe to the left. In the vertical pipe joint 13 having such a configuration, the vertical pipe drainage flowing down from the upstream drainage stack 17 collides with the turning guide 13d and is decelerated and flows down while producing a left turning flow along the pipe inner wall. Then, it is guided by the swirl vanes 13e, 13e and the left swirl flow is accurately adjusted and flows down to the drainage stack 17 on the downstream side. At this time, since the swivel guide 13d protrudes like a ridge above the inflow of the side branch pipe drainage, the vertical pipe drainage flows down avoiding the inflow of the side branch pipe drainage. It is possible to prevent the vertical drainage from flowing back to the inlet. Further, in the vertical pipe joint 13 having such a configuration, the side branch pipe drainage collides with the opposite surface of the side branch pipe drainage inlet and flows down into the left and right sides, and the swirl vanes 13e and 13e collide with each other. It flows down with a left swirling flow along the wall.

According to the drain pipe facility H1 of the first embodiment configured as described above, the toilet 11a of the toilet 11 is connected to the drain stand system 42 dedicated to the toilet. No other drainage device is connected to the drainage standpipe system 42 dedicated to the toilet, and only the sewage of the toilet 11a with less oil is drained. For this reason, the inside of the drainage standpipe system 42 dedicated to the toilet is very unlikely to accumulate dirt, and even when the apartment house is used for a long period of time, it is possible to extend the service life so that it does not require renewal. Therefore, the toilet 11 can hardly be used by updating the drainage stack system 42.
Moreover, according to this drainage pipe equipment H1, all drainage standpipe systems are piped in the 1st pipe space 40 provided in the common use hallway side, and it can ensure the space in the exclusive part S widely. And can easily cope with layout changes.
Since the drainage of the kitchen sink 7a with a disposer generally contains a relatively large amount of oil and solids, the drainage stand system 30 dedicated to kitchen sinks is particularly prone to dirt, and cleaning is required during long-term use of an apartment house. However, there are cases where an update is required. Moreover, since the drainage of the bathtub drain 5a, the washroom drain 5b, the washbasin drain 6b, and the washing machine drain 6a generally contains a relatively large amount of oil, the drainage is not possible during long-term use of the housing complex. Cleaning and renewal may be required in some cases. However, in the first embodiment, since the drainage stand system 30 dedicated to the kitchen sink and the common drainage stand system 17 are piped in the first pipe space 40 provided facing the corridor R, the corridor R can be easily cleaned and renewed.
Further, in the common drainage standpipe system 17, although a plurality of drainage devices are connected, they are connected one-to-one to the lateral branch pipe receiving ports 81 to 83 of the header joint 80. The cleaning operation of 70 is easier.

The present invention is not limited to the first embodiment, and can be implemented in various modified forms.
In the said 1st Embodiment, although drainage standpipe system 42 only for a toilet bowl was illustrated in the 1st pipe space 40 provided in the common use hallway side, it was distinguished from drainage equipment other than a toilet bowl. If only the toilet bowl is connected, the piping position is not limited. For example, a drainage standpipe system dedicated to a toilet may be piped on the balcony B side as indicated by a two-dot chain line in FIG. In FIG. 1, a drainage stack system 52 is piped through the balcony B. The drainage standpipe system 52 dedicated to the toilet includes a drainage standpipe 54 and a standpipe joint 56 provided with two side branch pipe receiving ports 56a and 56c and a cleaning port 56b around the trunk. The toilet 11a is connected through the branch pipe 58. In this way, when the drainage stack systems 42 and 52 dedicated to the toilet are provided in the common part on the corridor R side or the balcony B side, the layout change of the toilet 11 can be easily handled. Moreover, since the drainage standpipe systems 42 and 52 dedicated to the toilet bowl are piped to a portion other than the exclusive part S (shared part), the toilet 11a has a large load during drainage and noise is likely to be relatively large. Even if there is, it is difficult for residents on the lower floor to hear noise. Further, a plurality of drainage stacks 52 dedicated to the toilet can be connected at the same level as long as they are toilets. For example, a drain outlet 59a (an opening with a detachable lid to which a pipe end of a forced drainage distribution pipe can be connected) is provided in the exclusive part S in advance, and the side of the side where the toilet 11a is not connected via the lateral branch pipe 59 is provided. A toilet can be added by connecting to the branch pipe receiving port 56c, and connecting a forced drainage toilet for nursing care to the drain outlet 59a as necessary.
In addition, the drainage standpipe system dedicated to the toilet can be piped not only to the common part but also to the private part S in the dwelling unit as long as only the toilet is connected to the drainage device other than the toilet. For example, as illustrated by reference numeral 22 in FIG. 1, a second pipe space 20 can be provided adjacent to the toilet 11, and a drainage stand system 22 dedicated to a toilet can be provided. This drainage standpipe system 22 dedicated to the toilet is penetrated from the upper floor to the lower floor of the apartment building, and is interposed between the drainage standpipe 24 and the drainage standpipe 24 piped to each level. It is comprised with the vertical pipe joint 26 made. The vertical pipe joint 26 is provided with one side branch pipe receptacle around its trunk, and the appliance drain pipe 28 of the toilet 11a of the toilet 11 is directly connected thereto. Thus, if the exclusive drain stand system 22 is piped in the immediate vicinity of the toilet 11a, it is easy to ensure the gradient of the appliance drain pipe 28. In addition, when the drainage standpipe system 22 is piped to the dwelling unit exclusive part S, it is preferable to use the standpipe joint 26 with the cleaning port 26b as illustrated in FIG.
In addition, as a measure against complaints such as throwing cat sand (cat feces box sand) into the toilet bowl and flushing it when the toilet bowl is not used properly, two drainage standpipe systems dedicated to the toilet bowl are installed. It ’s even better.

Moreover, in the said 1st Embodiment, although drainage standpipe system 30 only for a kitchen sink was illustrated in the 1st pipe space 40 of the common use hallway side, the kitchen sink 7a was used for the exclusive drainage stand. When connecting to a pipe system, the piping position is not limited. For example, as shown by a two-dot chain line in FIG. In FIG. 1, a drainage standpipe system 72 dedicated to a kitchen sink comprising a drainage standpipe 74 and a standpipe joint 76 provided with a lateral branch pipe receiving port 76a and a cleaning port 76b around the trunk is penetrated into the balcony B. The kitchen sink 7a is connected to the side branch pipe receiving port 76a via the side branch pipe 71. Or you may pipe the drainage standpipe system only for a kitchen sink to the private part S in a dwelling unit, as shown as the code | symbol 60 with a dashed-two dotted line in FIG.
Further, as described above, the drainage standpipe system 30 dedicated to the kitchen sink is relatively likely to accumulate dirt. However, as a preferable piping configuration for reducing the update of the drainage standpipe system dedicated to the kitchen sink, a spare drainage standpipe is used. The following piping configuration in which the system is previously piped can be taken. That is, a drainage standpipe system 30 dedicated to the kitchen sink is connected in the first pipe space 40 on the common-use corridor side, and the kitchen sink 7a is connected through the side branch pipe 36. In FIG. As shown, a third pipe space 66 is provided adjacent to the kitchen sink 7a, and a drain standpipe system 60 dedicated to a spare kitchen sink is previously piped. The drainage standpipe system 60 dedicated to a spare kitchen sink is composed of a drainage standpipe 62 and a standpipe joint 64 disposed between the drainage standpipe 62, and is water-tight and in a receiving port 64 a provided around the trunk of the standpipe joint 64. The lid is airtightly attached, and the drain trap of the kitchen sink 7a is in an unconnected state in which it can be connected by the attached appliance drain pipe 7b. As described above, the drainage stand system 30 to which the kitchen sink 7a is connected is configured to be easily cleaned, but when it needs to be renewed due to long-term use, the standby sink system 60 is connected to the spare drainage stand system 60. By reconnecting 7a, the kitchen sink 7a can be used without updating the drainage stack system 30. In this case, if the horizontal branch pipe 36 and the drain trap of the kitchen sink 7a are connected by a disassembling joint, the side branch pipe 36 can be easily removed from the drain trap by disassembling the joint when changing the connection. This is preferable because the work of changing the connection becomes easier.
In this way, as a drainage standpipe system dedicated to kitchen sinks, two systems, a drainage standpipe system 30 piped to the common use corridor side, and a drainage standpipe system 60 piped to the dwelling unit exclusive part S are piped. In such a case, the drainage standpipe system 30 piped on the shared section corridor side can be reserved. In this case, the kitchen sink 7a is directly connected from the drain trap to the drainage stand system 60 by the attached appliance drain pipe 7b. By directly connecting the kitchen sink 7a to the drainage standpipe system 60, it is possible to prevent clogging of piping due to drainage of the sink 7a with a disposer having a relatively large solid content. In addition to the receiving port 64, a cleaning port 64 b is provided around the trunk of the vertical tube joint 64 so that the drainage stack system 60 can be cleaned. On the other hand, the spare drainage stand system 30 dedicated to the kitchen sink provided in the first pipe space 40 is previously piped in a non-connected state to which the kitchen sink 7a can be connected, and the drainage stand system 60 If renewal is required, reconnect the kitchen sink 7a. In order to make this switching work easier, it is preferable that a side branch pipe 36 for connecting the kitchen sink 7a and the spare drainage stand system 30 is connected from the vicinity of the kitchen sink 7a to the spare drainage stand system 30. It arrange | positions beforehand to the vicinity of. In that case, at the time of connection change, the upstream end of the side branch pipe 36 may be connected to the kitchen sink 7a, and the downstream end may be connected to the spare drainage stack system 30. More preferably, the downstream end of the horizontal branch pipe 36 is connected to the preliminary drainage stack 30 in advance, and the upstream end is sealed airtight and watertight. In that case, the kitchen sink 7a can be used by connecting the upstream end of the horizontal branch pipe 36 to the kitchen sink 7a, and the period during which the resident cannot use the kitchen sink 7a when switching the connection is further reduced. Can do.
Thus, when two systems are piped as a drainage standpipe system dedicated to kitchen sinks, the pipe positions of the two drainage standpipe systems are not limited to the common part corridor side and the private part S in the dwelling unit, but are shared. It may be piped anywhere on the side of the corridor, in the dwelling unit exclusive part S, or on the balcony B side. For example, the drainage standpipe systems 30 and 72 dedicated to the kitchen sink may be connected to the corridor R side and the balcony B side so that the connection can be changed. The drainage stand system that is no longer used due to the connection change may be withered as it is.
In addition, when the kitchen sink 7a is not equipped with a disposer or the like and can be drained by being combined with the drainage of other drainage devices, the kitchen sink 7a is not necessarily connected to a dedicated drainage stand system. In that case, if the toilet bowl 11a is connected to the dedicated drainage stand system 42 (22, 52) to distinguish it from other drainage devices, for example, the kitchen sink 7a is connected to other drainage devices. It is good also as a structure connected to the common drainage standpipe system 17.

Moreover, in the said Embodiment 1, although embodiment which piped the common drainage standpipe system 17 to the common part corridor side was illustrated, the piping position is not limited to this, Balcony B on the opposite side to the common part corridor side You may pipe on the side. The common drainage standpipe system 17 may be respectively piped to the common part corridor side and the balcony B side, and drainage devices other than the toilet 11a may be distributed and connected.
In addition, in the said 1st Embodiment (FIG. 1), although the inside of the 1st pipe space 40 adjacent to the exclusive part S was illustrated as a piping position of the drainage standpipe system of the common use part corridor side, it is not limited to this, For example, it may be piped through the hallway R, or may be piped along the outer wall surface of the hallway R.
The connection method of the header joint 80 to the vertical pipe joint 13 is not limited to the butt joining of the mounting flange portion 80d to the mounting seat 13a described above, but is joined by a conventional plug-in type (an end portion is inserted into a drain pipe joint receptacle). System).
The cleaning port for cleaning the drainage stand system may be provided in the standpipe joint as in the first embodiment or may be provided in the drainage standpipe.

It is a top view of a dwelling unit provided with the drain pipe equipment concerning a 1st embodiment of the present invention. It is a top view of a vertical pipe joint and the header joint connected to this.
