本発明は住宅排水システムにおいて使用する排水ヘッダーに関するものである。   The present invention relates to a drainage header for use in a residential drainage system.

近来、アパート等の小規模集合住宅や個人用住宅の排水システムとして、図8に示すように排水ヘッダーを使用する方式が提案されている。(特許文献1、特許文献2)
特開2002−61248号公報 特開2001−220789号公報
Recently, as a drainage system for a small apartment house such as an apartment or a private house, a system using a drainage header as shown in FIG. 8 has been proposed. (Patent Document 1, Patent Document 2)
JP 2002-61248 A Japanese Patent Laid-Open No. 2001-220789

図8において、8’は建物のコンクリート基礎、51’は建物内に設置されたトイレ、52’は洗面所、53’は台所、54’は洗濯機、55’は浴室等の排水設備である。100’は建物床下の所定位置に設置された排水ヘッダーであり、前記排水設備の箇数に応じた箇数の枝管接続口がヘッダー本管に設けられている。41’,…は各排水設備51’〜56’と排水ヘッダー100’の各枝管接続口との間を接続した排水枝管であり、可撓性管を用いることができ、必要に応じてY継手43’やエルボ45’が途中に設けられ、Y継手においては、空き接続口が栓体の装着により掃除口とされる。7’はコンクリート基礎外側の宅地内に埋設された排水桝、62’は排水ヘッダー100’の流出側接続口と排水桝7’の流入側接続口との間を曲がり継手44’を介し接続した排水主管であり、建物の床下に露出配設され、コンクリート基礎外周81’を貫通して排水桝7’に達している。620’は排水桝7’の流出側接続口に接続された排水主管であり、図示されていない公共桝に接続されている。
前記排水ヘッダー100’の上流最端は掃除口として使用され、常時は蓋体によって閉鎖されている。
In FIG. 8, 8 'is a concrete foundation of the building, 51' is a toilet installed in the building, 52 'is a washroom, 53' is a kitchen, 54 'is a washing machine, and 55' is a drainage facility such as a bathroom. . Reference numeral 100 'denotes a drainage header installed at a predetermined position under the building floor, and a number of branch pipe connection ports corresponding to the number of the drainage facilities are provided in the header main pipe. 41 ′,... Are drainage branch pipes connecting between the drainage facilities 51 ′ to 56 ′ and the branch pipe connection ports of the drainage header 100 ′, and flexible pipes can be used as necessary. A Y joint 43 ′ and an elbow 45 ′ are provided in the middle. In the Y joint, an empty connection port is used as a cleaning port by mounting a plug. 7 'is a drainage basin embedded in the housing ground outside the concrete foundation, 62' is connected between the outflow side connection port of the drainage header 100 'and the inflow side connection port of the drainage channel 7' via a bent joint 44 '. It is a drainage main pipe, is exposed and arranged under the floor of the building, penetrates the concrete foundation outer periphery 81 ′, and reaches the drainage basin 7 ′. 620 'is a drainage main pipe connected to the outflow side connection port of the drainage basin 7', and is connected to a public basin (not shown).
The upstream end of the drainage header 100 ′ is used as a cleaning port and is normally closed by a lid.

図8に示した新住宅排水システムは、旧来の住宅排水システム、すなわち図9に示すように、建物内のトイレ51’、洗面所52’、台所53’、洗濯機54’、浴室55’等の各排水設備に対応してコンクリート基礎外側の宅地内に桝71’〜75’を埋設し、各排水設備51’〜55’から各桝71’〜75’に向けコンクリート基礎外周81’を貫通して各排水枝管41’,…を配設し、これらの各排水枝管で41’,…各排水設備51’〜55’と各桝71’〜75’との間を接続し、桝71’〜72’〜73’〜74’〜75’間を排水主管62’,…で接続し、排水主管の直交箇所にも桝70’を設け、桝71’を排水主管620’により公共桝700’に接続した住宅排水システムと比較すると次のような利点を有する。
すなわち、(1)新システムは旧システムに較べコンクリート基礎外周の掘削貫通孔の箇数を少なくできる(上記の例では5箇から1個に減少できる)ので、コンクリート基礎外周の強度低下をよく排除できる。また、コンクリート基礎外周の掘削工事の労力、掘削孔の止水処理の手間を軽減できる。(2)新システムでは、排水主管を建物の床下に露出配管できるのに対し、旧システムでは屋外配管であるので地中に埋設する必要があり、新システムの方が排水主管の保守・点検を容易に行ない得る。(3)新システムでは、宅地内桝を全排水設備に対し共用できるので1個で済むが、旧システムでは、少なくとも個々の排水設備に対応した複数箇の宅地内桝を必要とし、新システムの方が、排水主管を露出敷設で済まし得ることとも相俟って掘削工事等の土工費用や桝等の部材コストをよく低減できる。(4)新システムでは、コンクリート基礎外側の宅地内に排水主管や2箇以上の複数箇の桝を埋設する必要がなく、狭い宅地でも住宅建設が可能である。また、コンクリート基礎外側の宅地を植栽等に有効に利用できる。
The new residential drainage system shown in FIG. 8 is an old residential drainage system, that is, as shown in FIG. 9, a toilet 51 ′, a washroom 52 ′, a kitchen 53 ′, a washing machine 54 ′, a bathroom 55 ′, etc. in the building. Corresponding to each drainage facility, ridges 71'-75 'are embedded in the residential land outside the concrete foundation, and through the concrete foundation outer periphery 81' from each drainage facility 51'-55 'to each ridge 71'-75' Are arranged between the drainage facilities 51 'to 55' and the rods 71 'to 75'. 71 ′ to 72 ′ to 73 ′ to 74 ′ to 75 ′ are connected by drainage main pipes 62 ′,..., 70 'is also provided at an orthogonal position of the drainage main pipe, and the pole 71 ′ is connected to the public drain by the drainage main pipe 620 ′. Compared with a residential drainage system connected to 700 ', it has the following advantages.
(1) Compared to the old system, the new system can reduce the number of drilling through holes on the outer periphery of the concrete foundation (in the above example, it can be reduced from five to one), thus eliminating the deterioration of the strength of the outer periphery of the concrete foundation. it can. In addition, the labor required for excavation work on the outer periphery of the concrete foundation and the trouble of water stop treatment for the excavation hole can be reduced. (2) In the new system, the drainage main pipe can be exposed under the floor of the building, whereas in the old system it is an outdoor pipe and it is necessary to bury it in the ground. The new system requires maintenance and inspection of the drainage main pipe. It can be done easily. (3) In the new system, the residential premises can be shared with all drainage facilities, so only one is required. However, the old system requires at least multiple residential premises corresponding to individual drainage facilities. However, coupled with the fact that the drainage main pipe can be completed by exposed laying, it is possible to well reduce earthwork costs such as excavation work and member costs such as dredging. (4) In the new system, it is not necessary to bury a drain main pipe or two or more pits in the residential land outside the concrete foundation, and it is possible to construct a house even in a small residential land. Moreover, the residential land outside the concrete foundation can be used effectively for planting and the like.

上記の新住宅排水システムでは、建物内のトイレ、洗面所、洗濯機、浴室、台所等の各排水設備からの排水を排水枝管を経て排水ヘッダーで一括集合させ、この集合排水を排水ヘッダーの排水流出口から排水主管を経て排水桝に向け流出していくから、排水設備に接続した枝管接続口から排水ヘッダーに流入した排水が他の枝管接続口に飛び込む畏れがある。これは旧住宅排水システムでは生じ得ないことである。
特許文献1では、排水ヘッダーとして図10に示すような90度大曲がりY継手1’を図11に示すように、交互に枝管接続口を本管中心軸を挾んで反対側に位置するように連ね、相互間をカラー11’を介し接着剤により連結したものが用いられている。
このように枝管接続口を本管中心軸を挾んで交互に反対側に配設することにより、配管の方向性に対する自由度を高くでき、また同一側での枝管接続口の間隔を広くでき、排水枝管の接続をそれだけ容易に行なうことができる。
In the new residential drainage system described above, wastewater from each drainage facility such as toilets, washrooms, washing machines, bathrooms, kitchens, etc. in the building is gathered together at the drainage header through the drainage branch pipe, and this collective drainage is collected in the drainage header. Since it flows out from the drainage outlet to the drainage basin through the drainage main pipe, the drainage flowing into the drainage header from the branch pipe connection port connected to the drainage facility may jump into the other branch pipe connection port. This is not possible with the old residential drainage system.
In Patent Document 1, a 90-degree bend Y joint 1 'as shown in FIG. 10 as a drainage header is alternately positioned on the opposite side with the branch pipe connection port sandwiching the main axis of the main pipe as shown in FIG. Are connected to each other by an adhesive via a collar 11 '.
Thus, by arranging the branch pipe connection ports alternately on the opposite side across the main axis, it is possible to increase the degree of freedom with respect to the directionality of the piping, and widen the interval between the branch pipe connection ports on the same side. The drainage branch pipes can be connected so easily.

しかしながら、本発明者の経験によれば、図11に示す排水ヘッダーでは、トイレに対する枝管接続口からの流入汚水がヘッダー下流側に隣の少量排水機器に対する枝管接続口、例えば、洗面所に対する枝管接続口に飛び込み侵入し、この侵入汚水中の汚物が滞留固化して配管詰りが発生することが往々にしてある。トイレに対する枝管接続口の流出側における、ヘッダー本管中心軸方向に直角方向の流れ成分が大きいほど、前記汚水の飛び込み侵入が生じ易い。90度大曲がりY継手は90度Y継手と同様、枝管接続口の流入側から本管管の中心方向に対し直角の方向(図11のF)からの排水を流入させるものであるが、その流入方向と本管管中心軸方向との間に曲面部を介在させてあり、接続口流入側のヘッダー本管中心軸方向に直角方向の流れ成分は90度Y継手に較べて大きい。しかし、45度Y継手よりも小さい。   However, according to the experience of the present inventor, in the drainage header shown in FIG. 11, the inflowing sewage from the branch pipe connection port to the toilet is on the downstream side of the header to the branch pipe connection port to the adjacent small amount drainage device, for example, the toilet. In many cases, pipes are clogged by jumping into the branch pipe connection port and entering and entering the sewage, and solidified and solidified. The larger the flow component in the direction perpendicular to the central axis of the header main pipe on the outflow side of the branch pipe connection port with respect to the toilet, the more likely the sewage enters and enters. Like the 90-degree Y joint, the 90-degree bent Y-joint allows drainage from the direction perpendicular to the central direction of the main pipe (F in FIG. 11) to flow from the inflow side of the branch pipe connection port. A curved surface portion is interposed between the inflow direction and the main pipe central axis direction, and the flow component in the direction perpendicular to the header main pipe central axis direction on the connection port inflow side is larger than that of the 90-degree Y joint. However, it is smaller than the 45 degree Y joint.

上記トイレからの排水枝管に接続した枝管接続口から流入する汚水がヘッダー下流側に隣の枝管接続口に飛び込み侵入する主な原因は、上流側の90度大曲がりY継手の枝管接続口の流出側のヘッダー本管中心軸方向に直角方向の流れ成分が相当に大きいこと及び上流側と下流側の両枝管接続口の離隔間隔が短か過ぎることにあると推察できる。   The main cause of the sewage flowing from the branch pipe connection port connected to the drainage branch pipe from the toilet into the adjacent branch pipe connection port on the downstream side of the header is the branch pipe of the 90-degree bent Y joint on the upstream side. It can be inferred that the flow component in the direction perpendicular to the central axis direction of the header main pipe on the outlet side of the connection port is considerably large, and that the separation interval between both the branch pipe connection ports on the upstream side and the downstream side is too short.

本発明の目的は、建物内に設置された複数の排水設備と建物床下に設置されたヘッダーの複数箇の枝管接続口との間がそれぞれ排水枝管で接続され、該ヘッダーの流出側接続口と建物の基礎外側の地中埋設排水桝の流入側接続口との間が建物床下の排水主管を介して接続された住宅排水システムにおける排水ヘッダーにおいて、トイレからの流入汚水が少量排水機器への枝管接続口内に飛び込むのを防止してスムーズな排水を保証すると共に排水ヘッダーを充分に短尺化することにある。   An object of the present invention is to connect a plurality of drainage facilities installed in a building and a plurality of branch pipe connection ports of a header installed under the building floor with drainage branch pipes, respectively, and to connect the outflow side of the header. In a drainage header in a residential drainage system where the entrance and the inflow side connection port of the underground drainage basin outside the foundation of the building are connected via a drainage main pipe under the building floor, inflow sewage from the toilet to a small amount of drainage equipment In other words, the drainage header is prevented from jumping into the branch pipe connection port to ensure smooth drainage, and the drainage header is sufficiently shortened.

請求項1に係る住宅排水システム用排水ヘッダーは、建物内に設置された複数の排水設備と排水枝管で接続されると共に、建物の基礎外側の地中埋設排水桝と排水主管で接続される住宅排水システム用ヘッダーにおいて、前記排水枝管と接続される前記ヘッダーの枝管接続口のうちの2つが、ヘッダーの上流側に鋭角の向きである第一枝管接続口と、前記第一接続口に対してヘッダーの下流側に隣りでかつヘッダーの中心軸を挟んで反対側に位置し、しかもヘッダーの上流側に45度、90度または90度大曲りの向きで前記排水管と接続される第二枝管接続口であり、この第一枝管接続口がトイレ用とされ、該第一枝管接続口と第二枝管接続口との間隔が第一枝管接続口からの流入水の第二枝管接続口への飛び込みを防止し得るように他の枝管接続口間の間隔とは異なる所定の間隔で前記ヘッダーに配置されていることを特徴とする。 The drainage header for a residential drainage system according to claim 1 is connected to a plurality of drainage facilities installed in the building by drainage branch pipes, and is connected to an underground underground drainage basin outside the building and a drainage main pipe. In the header for residential drainage system, two of the branch pipe connection ports of the header connected to the drainage branch pipe have a first branch pipe connection port having an acute angle direction upstream of the header, and the first connection It is adjacent to the outlet downstream of the header and on the opposite side across the central axis of the header, and connected to the drain pipe at an angle of 45 degrees, 90 degrees or 90 degrees on the upstream side of the header. The first branch pipe connection port is used for a toilet, and the distance between the first branch pipe connection port and the second branch pipe connection port is an inflow from the first branch pipe connection port. To prevent the water from jumping into the second branch connection port Characterized in that it is arranged on the header at different predetermined intervals with the spacing between the tube connection port.

請求項2に係る住宅排水システム用排水ヘッダーは、請求項1記載の住宅排水システム用排水ヘッダーにおいて、前記第一接続口がヘッダーの上流側に45度の向きであると共に、前記第二枝管接続口がヘッダーの上流側に90度の向きであり、かつこの第一枝管接続口の中心軸とヘッダーの中心軸との交点から、この第二枝管接続口の中心軸とヘッダーの中心軸との交点に至る距離が125mmから220mmとされていることを特徴とする。   The drainage header for residential drainage system according to claim 2 is the drainage header for residential drainage system according to claim 1, wherein the first connection port is oriented at 45 degrees upstream of the header, and the second branch pipe The connection port is oriented 90 degrees upstream of the header, and from the intersection of the central axis of the first branch pipe connection port and the central axis of the header, the center axis of the second branch pipe connection port and the center of the header The distance to the intersection with the shaft is 125 mm to 220 mm.

請求項3に係る住宅排水システム用排水ヘッダーは、請求項1記載の住宅排水システム用排水ヘッダーにおいて、前記第一接続口がヘッダーの上流側に45度の向きであると共に、前記第二枝管接続口がヘッダーの上流側に45度の向きであり、かつこの第一枝管接続口の中心軸とヘッダーの中心軸との交点から、この第二枝管接続口の中心軸とヘッダーの中心軸との交点に至る距離が170から265mmとされていることを特徴とする。   The drainage header for residential drainage system according to claim 3 is the drainage header for residential drainage system according to claim 1, wherein the first connection port is oriented at 45 degrees upstream of the header, and the second branch pipe From the intersection of the central axis of the first branch pipe connection port and the central axis of the header, the connection port is oriented at 45 degrees upstream of the header, and the center axis of the second branch pipe connection port and the center of the header The distance to the intersection with the axis is 170 to 265 mm.

請求項4に係る住宅排水システム用排水ヘッダーは、請求項2または3記載の住宅排水システム用排水ヘッダーにおいて、前記第一枝管接続口の中心軸と前記ヘッダー内面との交点からヘッダー中心軸までの距離が35mmから90mmとされていることを特徴とする。   The drainage header for residential drainage system according to claim 4 is the drainage header for residential drainage system according to claim 2 or 3, from the intersection of the central axis of the first branch pipe connection port and the inner surface of the header to the header central axis. The distance is 35 mm to 90 mm.

請求項5に係る住宅排水システム用排水ヘッダーは、請求項1から4何れか記載の住宅排水システム用排水ヘッダーにおいて、前記第一枝管接続口を有する部分、前記第二枝管接続口を有する部分またはその他の枝管接続口を有する部分とに、前記ヘッダーを長手方向に複数に分割し別体とし、この分割された複数の枝管接続口を有する部分の間が間隔調整用アダプタソケットにより連結されていることを特徴とする。   The drainage header for residential drainage system according to claim 5 is the drainage header for residential drainage system according to any one of claims 1 to 4, wherein the drainage header for residential drainage system has the first branch pipe connection port and the second branch pipe connection port. The header is divided into a plurality of parts in the longitudinal direction separately from a part or other part having a branch pipe connection port, and a gap adjusting adapter socket is provided between the divided parts having the plurality of branch pipe connection ports. It is connected.

請求項1〜3の住宅排水システム用排水ヘッダーでは、上流方向に対し45度の第一枝管接続口と、この第一枝管接続口に対し下流側に隣りでヘッダー本管中心軸を挾んで反対側に位置した45度または90度の向きあるいは90度大曲がりの第二枝管接続口との間の距離を、前者からのヘッダー内への流入排水を後者への飛び込みを防止し得る所定の距離に設定しているから、その飛び込みを防止できる。従って、前者の枝管接続口がトイレに連通され、後者の枝管接続口が洗面所のような少量排水機器に連通されても、後者への汚水の飛び込みを防止し得、飛び込み汚水の滞留固化に起因する配管詰りを排除できる。
しかも、45度の向きの枝管接続口では、90度大曲がりの枝管接続口よりも、トイレに対する枝管接続口の流出側における、ヘッダー本管中心軸方向に直角方向の流れ成分が小さく、汚水の飛び込み侵入が生じ難いから、前記飛び込み防止のための必要間隔をそれだけ短くでき、排水ヘッダーの短尺化を達成できる。
In the drainage header for a residential drainage system according to claims 1 to 3, the first branch pipe connection port at 45 degrees with respect to the upstream direction and the header main axis adjacent to the downstream side of the first branch pipe connection port The distance between the second branch pipe connection port of 45 degrees or 90 degrees or a large bend of 90 degrees located on the opposite side can be prevented from flowing into the header from the former into the latter. Since it is set to a predetermined distance, it is possible to prevent the jump. Therefore, even if the former branch pipe connection port communicates with the toilet and the latter branch pipe connection port communicates with a small amount of drainage equipment such as a washroom, the sewage can be prevented from entering the latter, Piping clogging caused by solidification can be eliminated.
Moreover, the branch pipe connection port oriented at 45 degrees has a smaller flow component in the direction perpendicular to the central axis direction of the header main pipe on the outflow side of the branch pipe connection port with respect to the toilet than the branch pipe connection port bent 90 degrees. In addition, since it is difficult for sewage to enter, it is possible to shorten the interval necessary for preventing the entry, and to shorten the drainage header.

請求項4の住宅排水システム用排水ヘッダーでは、図4に示す上流側の45度の第一枝管接続口の流出中心点pからヘッダー本管の中心軸n−nに至る距離Rを大きくするほど、前記汚水の飛び込みエネルギーを事前によく消費させ得るところ、この距離Rを充分に大きくしているのでその飛び込みをよく防止できる。反面、この距離を大きくし過ぎると、排水ヘッダーの径大化を伴い、ヘッダー本管内の水位低下のために掃流性も低下するが、その距離に所定の上限を設定しているので、排水ヘッダーを充分に径小化でき、良好な掃流性を保証できる。   In the drainage header for residential drainage system according to claim 4, the distance R from the outflow center point p of the 45-degree first branch pipe connection port on the upstream side shown in FIG. 4 to the central axis nn of the header main pipe is increased. The sewage dive energy can be consumed well in advance, but since this distance R is sufficiently large, the dive can be well prevented. On the other hand, if this distance is too large, the drainage header will become larger in diameter, and the scavenging performance will also decrease due to the lowering of the water level in the header mains. The diameter of the header can be sufficiently reduced, and good scavenging performance can be guaranteed.

請求項5の住宅排水システム用排水ヘッダーでは、枝管接続口単位でユニット化したヘッダー片の連結により排水ヘッダーを組み立てる場合、前記上流側の45度の第一枝管接続口を有するヘッダー片と下流側に隣りで、かつヘッダー本管中心軸を挾んで反対側に位置する45度または90度の第二枝管接続口を有するヘッダー片との間を長さ調整用アダプタソケットにより連結することにより請求項1〜3の構成にでき、ヘッダーの製作が容易である。   In the drainage header for a residential drainage system according to claim 5, when assembling a drainage header by connecting header pieces unitized in units of branch pipe connection ports, a header piece having a first branch pipe connection port of 45 degrees on the upstream side, A length adjusting adapter socket is used to connect a header piece having a second branch pipe connection port of 45 degrees or 90 degrees located on the opposite side of the header main axis adjacent to the downstream side. Therefore, the header can be easily manufactured.

以下、図面を参照しつつ本発明の実施の形態について説明する。

上記45度枝管接続口10及び90度枝管接続口12以外の枝管接続口は、上記の両枝管接続口に対し上流側または下流側の何れに位置させてもよく、また、ヘッダー本管中心軸を基準として同じ側あるいは反対側の何れに配置させてもよく、また、全体が交互に反端側となるように位置させてもよい。
下流側流出口と反対側の上流最端口は枝管接続口または掃除口として使用される。掃除口として使用する場合、常時は蓋体または栓体の装着で閉塞される。

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an essential part of an embodiment of a drainage header for a residential drainage system according to claim 1.
In FIG. 1, 10 indicates a header main body, and an arrow indicates a downstream direction. The cross section of the header main pipe is usually circular, but may be oval or the like as will be described later. 11 is a branch pipe connection port that is oriented at an acute angle with respect to the upstream direction, and 12 is a branch pipe connection port that is adjacent to the branch pipe connection port on the downstream side and located on the opposite side of the header main axis. In addition to the illustrated 90-degree branch pipe connection port, a 45-degree branch pipe connection port and a 90-degree bent branch pipe connection port can be used. The central axis of each branch pipe connection port intersects the central axis of the header main pipe.
The diameter of the header main pipe 10 is usually larger than the diameter of the branch pipe connection ports 11 and 12, for example, the former is 100 mm and the latter is 30 to 70 mm.
The minimum number of branch pipe connection ports provided in the header main 10 corresponds to the sewage system of the toilet and the miscellaneous system other than the toilet, usually the toilet, washroom, washing machine, bathroom, and kitchen. And can be seven.
The branch pipe connection ports other than the 45-degree branch pipe connection port 10 and the 90-degree branch pipe connection port 12 may be located on either the upstream side or the downstream side with respect to the both branch pipe connection ports. You may arrange | position on the same side or the opposite side on the basis of the main axis of a main pipe, and you may arrange | position so that the whole may become an other end side alternately.
The upstream endmost port opposite to the downstream outlet is used as a branch pipe connection port or a cleaning port. When used as a cleaning port, it is normally closed by attaching a lid or a plug.
The material of the drainage header can be synthetic resin such as vinyl chloride resin and polyethylene, preferably transparent, translucent or transparent, and can be manufactured by injection molding.

上流側の45度枝管接続口11にはトイレからの排水枝管を、下流側に隣りでかつヘッダ本管中心軸を挾んで反端側に位置する枝管接続口12には少量排水機器例えば洗面所からの排水枝管をそれぞれ接続することができる。
図1において、上流側の鋭角枝管接続口11の角度をθ、鋭角枝管接続口11の流入側に流入する汚水流れをFとすると、この流れFのヘッダー本管中心軸方向に直角方向の流れ成分Fsinθが下流側に隣りで、かつヘッダー本管中心軸を挾んで反対側に位置する枝管接続口12への汚水の飛び込みのエネルギーを分担し、この流れ成分Fsinθが小である程、上流側枝管接続口11とその下流側に隣りで、かつヘッダー本管中心軸を挾んで反対側に位置する枝管接続口12との間の距離を短くして前記の飛び込みを防止できる。
而るに、請求項1の排水ヘッダーでは、上流側枝管接続口11の角度θを鋭角としており、実質的に90度大曲がり枝管接続口よりも流れ成分Fsinθを小さくできるから、短いヘッダー長さで上記した汚水の飛び込みを防止できる。
A 45-degree branch pipe connection port 11 on the upstream side is a drainage branch pipe from the toilet, and a small drainage device is located on the branch pipe connection port 12 adjacent to the downstream side and on the opposite end side of the header main axis. For example, drainage branch pipes from the bathroom can be connected to each other.
In FIG. 1, assuming that the angle of the upstream acute branch pipe connection port 11 is θ and the sewage flow flowing into the inflow side of the acute branch connection port 11 is F, the flow F is perpendicular to the header main axis direction. The flow component Fsinθ is adjacent to the downstream side and shares the energy of sewage jumping into the branch pipe connection port 12 located on the opposite side across the header main axis, and the smaller this flow component Fsinθ is, the smaller the flow component Fsinθ is. The jumping can be prevented by shortening the distance between the upstream side branch pipe connection port 11 and the branch pipe connection port 12 located on the opposite side of the header main pipe adjacent to the downstream side.
Accordingly, in the drainage header of claim 1, the angle θ of the upstream branch pipe connection port 11 is an acute angle, and the flow component Fsinθ can be made substantially smaller than that of the branch pipe connection port bent by 90 degrees. Now, the sewage can be prevented from entering.

上記流れFのヘッダー本管中心軸方向成分Fcosθを大とするほど、ヘッダー本管内での汚物の沈滞をよく防止でき、掃流性を高くして流れ抵抗の増加を防止でき、下流側に隣りで、かつヘッダー本管中心軸を挾んで反対側に位置するの枝管接続管12への汚物のひっかかりをよく防止できる。
而るに、鋭角の枝管接続口11では、前記ヘッダー本管中心軸方向成分Fcosθが90度大曲がり枝管接続口よりも大きく、下流側に隣りで、かつヘッダー本管中心軸を挾んで反対側に位置する枝管接続口12への汚物のひっかかりをよく防止できる。
従って、上流側枝管接続口が90度大曲がり枝管接続口である従来の排水ヘッダー使用の場合に往々にして観られる、「上流側枝管接続口からの汚水の下流側に隣りで、かつヘッダー本管中心軸を挾んで反対側に位置する枝管接続口への飛び込みで付着した汚物やひっかかった汚物がその下流側枝管接続口内の掃流流量が小量であるために乾燥固化されて生じる配管詰まり」を、良好に防止できる。
The larger the component Fcosθ in the header main axial direction of the flow F, the better the prevention of stagnation of filth in the header main can be achieved, and the increase in the flow resistance can be prevented. In addition, it is possible to prevent the filth from being caught on the branch pipe connecting pipe 12 located on the opposite side of the header main axis.
Accordingly, in the acute-angle branch pipe connection port 11, the header main axis direction component Fcosθ is 90 degrees larger than that of the branch pipe connection port, adjacent to the downstream side and sandwiching the header main axis. It is possible to satisfactorily prevent filth from being caught on the branch pipe connection port 12 located on the opposite side.
Therefore, it is often seen when using a conventional drainage header in which the upstream side branch pipe connection port is a 90-degree bent branch pipe connection port, “the header next to the downstream side of the sewage from the upstream side branch pipe connection port. Dirt adhered and trapped by jumping into the branch pipe connection port located on the opposite side of the main pipe central axis is dried and solidified due to the small amount of the sweep flow in the downstream branch pipe connection port. “Clogging of piping” can be prevented well.

FIG. 2 shows a main part of an embodiment of a drainage header for a residential drainage system according to claim 2.
In FIG. 2, 10 is a header main pipe, 110 is a branch pipe connection port oriented at 45 degrees with respect to the upstream direction, 120 is adjacent to the branch pipe connection port 110 on the downstream side, and sandwiches the header main axis. It is a branch pipe connection port with a 90 degree orientation located on the opposite side, and the central axis of each branch pipe connection port intersects the central axis of the header main pipe. a is the intersection of the central axis of the 45-degree branch pipe connection port 110 on the upstream side and the central axis of the header main pipe 10, and b is located on the opposite side of the header main axis next to the downstream side and 90 on the opposite side. The intersection of the center axis of the branch pipe connection port 120 and the center axis of the header main pipe 10 is shown.
The total number of branch pipe connection ports provided in the header main pipe is 2 to 7 as described above, and the upstream end port on the opposite side to the downstream outlet port is used as a cleaning port or a branch pipe connection port. .
The branch pipe connection ports other than the 45 degree branch pipe connection port 110 and the 90 degree branch pipe connection port 120 located on the opposite side of the header main pipe adjacent to the downstream side of the 45 degree branch pipe connection port It may be located either upstream or downstream with respect to the pipe connection port, and may be arranged on the same side or on the opposite side with respect to the central axis of the header main pipe. You may position it so that it may become an end side.
Similarly to the above, the drainage header can be made of transparent or translucent vinyl chloride resin or polyethylene, and can be manufactured by injection molding.
The distance L between the two intersections ab matches the distance between both branch pipe connection ports and is set to 125 mm to 220 mm.

この両枝管接続口110,120間の間隔Lを125mm〜220mmとした理由は、図2に示す上流側の45度枝管接続口の流出中心点からヘッダー本管の中心軸に至る距離が前記汚水の飛び込エネルギーの事前消費による軽減に寄与するところ、両枝管接続口の間隔125mm未満では前記飛び込みを防止するのにヘッダー本管内径を相当に大きくする必要があり、ヘッダー本管内の水位低下による掃流性の低下、ヘッダー本管の径大化が招来され、両枝管接続口の間隔が220mmを超えるとヘッダーの必要以上の長尺化が招来されるからである。   The reason why the distance L between the branch pipe connection ports 110 and 120 is 125 mm to 220 mm is that the distance from the outflow center point of the 45 degree branch pipe connection port on the upstream side shown in FIG. Contributing to the reduction of the wastewater jumping energy in advance, it is necessary to considerably increase the inner diameter of the header main pipe in order to prevent the jumping if the distance between the branch pipe connection ports is less than 125 mm. This is because a decrease in the scavenging property due to a drop in the water level and an increase in the diameter of the header main pipe are caused, and if the distance between both branch pipe connection ports exceeds 220 mm, the header becomes longer than necessary.

FIG. 3 shows an essential part of an embodiment of a drainage header for a residential drainage system according to claim 3.
In FIG. 3, 10 is a header main pipe, 110 is a branch pipe connection port oriented at an angle of 45 degrees with respect to the upstream direction, and 1200 is downstream of this branch pipe connection port 110 and sandwiches the central axis of the header main pipe. It is a branch pipe connection port located on the opposite side and oriented 45 degrees in the upstream direction, and the central axis of each branch pipe connection port intersects the central axis of the header main pipe. a is the intersection of the central axis of the 45 degree branch pipe connection port 110 on the upstream side and the central axis of the header main pipe 10, and b 'is located on the opposite side adjacent to the downstream side and across the header main axis. Further, the intersection of the central axis of the 45-degree branch pipe connection port 1200 and the central axis of the header main pipe 10 is shown.
The total number of branch pipe connection ports provided in the header main pipe 10 is 2 to 7 as described above, and the upstream endmost port opposite to the downstream outlet is used as a cleaning port or a branch pipe connection port. The
The branch pipe connection ports other than the 45 degree branch pipe connection port 110 and the 45 degree branch pipe connection port 1200 located on the opposite side of the header main pipe adjacent to the downstream side of the 45 degree branch pipe connection port are the both branch pipes. It may be located either upstream or downstream with respect to the connection port, and may be located either on the same side or on the opposite side with respect to the central axis of the header main pipe. You may make it become the side.
Similarly to the above, the drainage header can be made of transparent or translucent vinyl chloride resin or polyethylene, and can be manufactured by injection molding.
The distance L ′ between the two intersections ab ′ coincides with the distance between the two branch pipe connection ports 110 and 1200 and is set to 170 mm to 265 mm.

この距離L’=170〜265mmが図2に示した請求項2に係る住宅排水システム用排水ヘッダーでの距離L=125〜220に較べて長い理由は、45度枝管接続口1200がヘッダー本管内面に開口する広さと90度枝管接続口120がヘッダー本管内面に開口する広さとの比がほぼ(1/cos45°)倍、すなわち√2倍であり、開口広さが大きいほどそれだけ飛び込みが生じ易く、その飛び込みを防止するには、飛び込み防止のための前記間隔を大きくする必要があるからである。   The reason why this distance L ′ = 170 to 265 mm is longer than the distance L = 125 to 220 in the drainage header for residential drainage system according to claim 2 shown in FIG. 2 is that the 45 ° branch pipe connection port 1200 is the header book. The ratio of the width that opens to the inner surface of the pipe to the width that the 90 degree branch pipe connection port 120 opens to the inner surface of the header main pipe is approximately (1 / cos 45 °) times, that is, √2 times. This is because jumping is likely to occur, and in order to prevent such jumping, it is necessary to increase the interval for preventing jumping.

図4に示す上流側の45度枝管接続口110の開口中心p(45度枝管接続口の中心軸とヘッダー本管内面との交差点)からヘッダー本管10の中心軸n−nに至る間で、上流側の45度枝管接続口10の開口中心pから流出された流れのエネルギーの一部が消費されるから、この距離を大とするほど、45度枝管接続口110からの汚水の下流側に隣りでかつ反対側に位置する枝管接続口への飛び込みをよく防止できる。しかしながら、この間隔を大きくし過ぎると、ヘッダー本管10の内径が大きくなって排水ヘッダーの径大化が招来される。また、短か過ぎると、ヘッダー本管10の内径が小さくなりすぎてヘッダー本管内の流動抵抗が高くなり、搬送性の低下が避けられない。従って、上流側の45度の向きの枝管接続口110の中心軸とヘッダー本管10の内面との交点pからヘッダー本管10の中心軸n−nまでの距離Rは35〜90mmとすることが好ましい。   From the opening center p of the 45-degree branch pipe connection port 110 on the upstream side shown in FIG. 4 (intersection of the central axis of the 45-degree branch pipe connection port and the inner surface of the header main pipe) to the central axis nn of the header main pipe 10. In the meantime, a part of the energy of the flow flowing out from the opening center p of the 45-degree branch pipe connection port 10 on the upstream side is consumed. Therefore, as the distance increases, the distance from the 45-degree branch pipe connection port 110 increases. Jumping into the branch pipe connection port located next to the downstream side of the sewage and on the opposite side can be well prevented. However, if this interval is too large, the inner diameter of the header main pipe 10 becomes large, leading to an increase in the diameter of the drainage header. On the other hand, if the length is too short, the inner diameter of the header main pipe 10 becomes too small, the flow resistance in the header main pipe becomes high, and a decrease in transportability cannot be avoided. Accordingly, the distance R from the intersection point p between the central axis of the branch pipe connection port 110 facing 45 degrees upstream and the inner surface of the header main pipe 10 to the central axis nn of the header main pipe 10 is set to 35 to 90 mm. It is preferable.

前記ヘッダー本管の断面は、円形の外、卵形、縦長の楕円形や長円形とすることもできる。卵形等とすれば、同一断面積・同一流量のもとで水位を高くできるから、汚物をよく浮遊させ得て掃流性を高くできる。
