Description

本発明は、複数の排水管からの排水を一系統の排水管に集約して排水する際に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 drain header used when draining water from a plurality of drain pipes into a single drain pipe.

従来より建物内部の排水管工事の簡略化を図るために、複数の器具排水管を1ヶ所に集中させ、各器具からの排水を合流させて排水桝排水管に流す排水ヘッダーが開発されてきた。従来の排水ヘッダーは建物の1階床下空間に設置されることが多く、点検、清掃等の作業が行い難いという問題があった。   In order to simplify the construction of drainage pipes inside buildings, drainage headers have been developed in which multiple equipment drainage pipes are concentrated in one place, and the drainage from each equipment is merged into a drainage drainage pipe. . Conventional drainage headers are often installed in the space under the first floor of a building, and there is a problem that it is difficult to perform operations such as inspection and cleaning.

尚、ここで器具排水管とは、排水ヘッダーと排水ヘッダーよりも上流に設置される器具とを接続する排水管である。また、排水桝排水管とは排水ヘッダーと排水ヘッダーよりも下流に設置される排水桝とを接続する排水管である。   Here, the appliance drain pipe is a drain pipe connecting the drain header and the appliance installed upstream of the drain header. The drainage drainage pipe is a drainage pipe that connects a drainage header and a drainage drain installed downstream from the drainage header.

この問題を解決する為の手段として、特許文献1のような排水システムが提案されている。これは、外周基礎に設けた開口部の近傍に集合排水桝(排水ヘッダー)を設けて建物外部から作業を行い得るように構成したものであり、建物の内部に入る必要や床下に潜る必要がないので作業性が向上する、とされている。   As a means for solving this problem, a drainage system as in Patent Document 1 has been proposed. This is configured so that a collective drainage (drainage header) can be installed near the opening provided on the outer periphery foundation so that the work can be performed from outside the building, and it is necessary to enter the building or to dive under the floor. It is said that workability is improved because there is not.

特開2005−256284号公報JP 2005-256284 A

しかしながら、外周基礎近傍の開口部とは言え、建物の外周基礎の領域内、即ち床下空間であることに変わりはなく、実施にあたっては以下のような問題の発生が懸念され、作業性に関しては改善の余地がある。(1)集合排水桝の内部を直接目視して清掃状況を確認することが出来ない。(2)開口部から枝管や主管までが直線的でなく分岐も多いので清掃器具を目的の枝管や主管まで到達させることが難しい。(3)蓋体が床下に位置する場合は[i1] 開閉作業がし難い。(4)蓋を誤って布基礎内部へ[i2] 落下させてしまうと拾い上げるのに手間がかかる。   However, although it is an opening in the vicinity of the outer periphery foundation, it is still in the area of the outer periphery foundation of the building, that is, the space under the floor. There is room for. (1) The cleaning situation cannot be confirmed by directly observing the inside of the collective drainage basin. (2) Since the opening to the branch pipe and the main pipe are not straight and there are many branches, it is difficult to make the cleaning tool reach the target branch pipe or the main pipe. (3) When the lid is located under the floor, [i1] It is difficult to open and close. (4) If the lid is accidentally dropped into the fabric foundation [i2], it will take time to pick it up.

本発明は、上記従来技術の課題を解決し、より作業性に優れた排水ヘッダーを提供することを目的とする。   An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a drainage header with better workability.

本発明に係る排水ヘッダーの第1の構成は、建物外周部布基礎の上端部に形成された凹部の形状に対応した幅と高さを有する形状であり、前面部の開口には着脱可能な点検蓋を備え、背面部或いは前記布基礎から建物内部側に突出した底面部に排水桝側接続部を備え、前記排水桝側接続部よりも上方或いは上面部に器具側接続部を備えたことを特徴とする。   1st structure of the drainage header which concerns on this invention is a shape which has the width | variety and height corresponding to the shape of the recessed part formed in the upper end part of a building outer peripheral part cloth foundation, and it can be attached or detached to opening of a front part. An inspection lid was provided, a drainage basin side connection part was provided on the back surface or the bottom part protruding from the cloth foundation to the inside of the building, and an appliance side connection part was provided above or above the drainage basin side connection part. It is characterized by.

ここで器具側接続部とは、器具排水管を接続する部分、また、排水桝側接続部とは、排水桝排水管を接続する部分である。   Here, the appliance side connection part is a part for connecting the appliance drain pipe, and the drainage side connection part is a part for connecting the drainage drainage pipe.

本発明に係る排水ヘッダーの第2の構成は、前記第1の構成において、前記器具側接続部を前記排水ヘッダー本体の上面部の壁体内の空隙の略直下に形成したことを特徴とする。   A second configuration of the drainage header according to the present invention is characterized in that, in the first configuration, the appliance side connection portion is formed substantially immediately below a gap in the wall of the upper surface portion of the drainage header body.

本発明に係る排水ヘッダーの第3の構成は、前記第1、第2の構成において、前記器具側接続部を1階床に埋設されるように前記排水ヘッダー本体の上面部から突出して形成したことを特徴とする。   A third configuration of the drainage header according to the present invention is formed by projecting from the upper surface portion of the drainage header main body so that the appliance side connection portion is embedded in the first floor in the first and second configurations. It is characterized by that.

本発明に係る排水ヘッダーの第4の構成は、前記第1〜第3の構成において、該排水ヘッダー本体の内部に排水を前記排水桝側接続部方向に案内する傾斜面を形成したことを特徴とする。   A fourth configuration of the drainage header according to the present invention is characterized in that, in the first to third configurations, an inclined surface that guides drainage toward the drainage basin side connection portion is formed inside the drainage header body. And

本発明に係る排水ヘッダーの第5の構成は、前記第1〜第4の構成において、前記点検蓋に通気兼オーバーフロー水排出用の孔を設けたことを特徴とする。   A fifth configuration of the drainage header according to the present invention is characterized in that, in the first to fourth configurations, the inspection lid is provided with a hole for venting and overflowing water discharge.

本発明に係る排水ヘッダーの第1の構成によれば、建物外周部布基礎の上端部に形成された凹部に配置された排水ヘッダー本体(本発明)へ、排水桝側接続部と器具側接続部が集中し、前面部すなわち建物の外部側の開口に点検蓋を備えているので、点検蓋を取り外すことにより排水ヘッダー内部や排水桝側接続部と器具側接続部の状況が目視で確認出来、排水ヘッダー内部の清掃のみならず、排水桝排水管や器具排水管へ清掃器具を挿入して清掃することも容易である。   According to the first configuration of the drainage header according to the present invention, the drainage side connection part and the appliance side connection to the drainage header body (the present invention) disposed in the recess formed in the upper end of the building outer peripheral fabric foundation Since there is an inspection lid on the front side, that is, the opening on the outside of the building, the inside of the drainage header, the drainage side connection part, and the appliance side connection part can be visually confirmed by removing the inspection lid. It is easy not only to clean the inside of the drain header but also to clean it by inserting a cleaning instrument into the drainage drain pipe or the instrument drain pipe.

また、点検蓋の着脱作業が容易であり、布基礎上端部の凹部は排水ヘッダー本体により塞がれるので点検蓋や点検蓋固定部品(ビスなど)、工具等が建物床下に落下することもない。   Also, the inspection lid can be easily attached and removed, and the recess at the upper end of the fabric foundation is closed by the drainage header body, so that the inspection lid, inspection lid fixing parts (screws, etc.), tools, etc. do not fall under the building floor. .

本発明に係る排水ヘッダーの第2の構成によれば、器具側接続部を上面部の壁体内の空隙の略直下に形成したので、壁体内を立ち下げた上階からの排水管を曲げることなく接続することが出来るので、排水管内部の詰まりも生じ難く、また万一詰まっても清掃器具が挿入し易いので清掃作業性も向上する。   According to the 2nd structure of the drainage header which concerns on this invention, since the instrument side connection part was formed just under the space | gap in the wall body of an upper surface part, the drainage pipe from the upper floor which fell the wall body is bent. Therefore, it is difficult to cause clogging in the drain pipe, and even if clogged, the cleaning tool can be easily inserted, so that the cleaning workability is improved.

本発明に係る排水ヘッダーの第3の構成によれば、器具側接続部を1階床に埋設されるように上面部から突出して形成したので、排水ヘッダーに固定手段を付加しなくとも、1階床パネルの周囲をモルタルなどで充填固定すれば、同時に排水ヘッダーを所定の位置に固定することが出来、施工性を向上させることが出来る。   According to the 3rd structure of the drainage header which concerns on this invention, since the instrument side connection part protruded and formed from the upper surface part so that it might be embed | buried under the 1st floor, even if it does not add a fixing means to a drainage header, 1 If the periphery of the floor panel is filled and fixed with mortar or the like, the drainage header can be fixed at a predetermined position at the same time, and workability can be improved.

本発明に係る排水ヘッダーの第4の構成によれば、器具側接続部内部に排水を排水桝側接続部方向に案内する傾斜面を形成したので、排水の流れがスムーズとなり排水に混入した異物が排水ヘッダー内部に残留することを防止出来る。   According to the 4th structure of the drainage header which concerns on this invention Since the inclined surface which guides drainage in the direction of a drainage basin side connection part was formed in the appliance side connection part, the flow of drainage became smooth and the foreign material mixed in drainage Can be prevented from remaining inside the drainage header.

本発明に係る排水ヘッダーの第5の構成によれば、点検蓋に通気とオーバーフロー水排出の為の孔を設けたので、器具排水管内部に空気が混入した場合であっても排水ヘッダーで空気を分離することができるので、排水管中に空気が閉じ込められることに由来する排水障害を解消することができる。また万一、排水桝側での詰まり等により排水が滞った場合もオーバーフロー水を速やかに建物外部に排出することが出来る。   According to the fifth configuration of the drainage header according to the present invention, the inspection lid is provided with holes for ventilation and overflow water discharge, so even if air is mixed into the instrument drainage pipe, Can be separated, so that it is possible to eliminate a drainage failure caused by air trapped in the drainpipe. In the unlikely event that the drainage stagnates due to clogging on the drainage side, overflow water can be quickly discharged outside the building.

特に器具排水管の排水方式がサイホンの原理を利用したものである場合、サイホンの妨げとなる器具排水管内部の空気を当該孔から押し出すことが容易となるため、速やかに排水を開始させることが出来る。尚、サイホンの原理を利用した排水システムとは、比較的小径の排水管内部を略満排水状態として流下させることで、後続排水を吸引搬送する排水システムである。   In particular, when the drainage method of the instrument drain pipe uses the principle of siphon, it is easy to push out the air inside the instrument drain pipe that interferes with the siphon from the hole, so drainage can be started quickly. I can do it. The drainage system using the principle of siphon is a drainage system that sucks and conveys the subsequent drainage by letting the inside of the relatively small-diameter drainage pipe flow down in a substantially full drainage state.

以下、排水ヘッダーの最も好ましい実施形態について説明する。   Hereinafter, the most preferable embodiment of the drainage header will be described.

(建物側の構成)
外周部に布基礎が形成され、該布基礎上端面よりも高い位置に1階床面が形成され、床下に排水管を配管し得る空間が確保された建物であればいかなる形式の建物でも良い。
(Building side configuration)
Any type of building may be used as long as a fabric foundation is formed on the outer periphery, a first floor is formed at a position higher than the upper end surface of the fabric foundation, and a space is provided for piping a drain pipe below the floor. .

外周部布基礎上端部に形成される凹部の大きさは特に限定されるものではないが、布基礎に設ける床下換気孔と同一形状であることが好ましい。このように構成することで床下換気孔と同一の型枠が使用出来、施工性が高まる。   Although the magnitude | size of the recessed part formed in an outer peripheral part cloth foundation upper end part is not specifically limited, It is preferable that it is the same shape as the underfloor ventilation hole provided in a cloth foundation. By comprising in this way, the same formwork as an underfloor ventilation hole can be used, and workability improves.

(排水ヘッダーの構成)
排水ヘッダーの本体は前記凹部にほぼ隙間なく納まる箱状であり、本体の前面部に開口を塞ぐ点検蓋と、本体の上面部、底面部、背面部に複数の排水管接続部とを設けたものである。材質は腐食変形等が発生し難いものであればいかなるものでも構わないが、排水管工事で一般的に用いられる塩ビ管との接続が容易で、腐食にも強い硬質ポリ塩化ビニルとするのが好ましい。
(Drainage header configuration)
The main body of the drainage header has a box shape that fits in the recess with almost no gap, and has an inspection lid that closes the opening on the front surface of the main body, and a plurality of drain pipe connection portions on the top, bottom, and back of the main body. Is. Any material can be used as long as it does not easily cause corrosion deformation, but it should be made of rigid polyvinyl chloride that is easy to connect to PVC pipes commonly used in drainage pipe construction and is resistant to corrosion. preferable.

(排水管接続部の構成)
また、前記排水管接続部には、器具から排出された排水を排水ヘッダーに導く器具排水管を接続する器具側接続部と、排水を排水ヘッダーから排水桝へ導く排水桝排水管を接続する排水桝側接続部とがある。
(Configuration of drain pipe connection)
In addition, the drainage pipe connection part is connected to an appliance side connection part that connects an instrument drainage pipe that guides drainage discharged from the instrument to the drainage header, and a drainage pipe that connects drainage drainage pipe that guides drainage from the drainage header to the drainage drainage. There is a heel side connection part.

器具側接続部は、上面部に設けても良いし、背面部の排水桝側接続部よりも高い位置に設けても良い。また、排水桝側接続部は、背面部下端に設けても良いし、底面部を建物床下方向へ突出させ突出した底面部に設けても良い。尚、点検、清掃等の作業上、排水管接続部を上面部や下面部に形成する場合は、排水管接続部はなるべく前面寄り(点検蓋寄り)に配置するのが好ましい。   The appliance side connection portion may be provided on the upper surface portion, or may be provided at a position higher than the drainage side connection portion on the back surface portion. Further, the drainage side connection portion may be provided at the lower end of the back surface portion, or may be provided on the bottom surface portion that protrudes by causing the bottom surface portion to project downward from the building floor. In the case of forming the drain pipe connection part on the upper surface part or the lower surface part for work such as inspection and cleaning, it is preferable to arrange the drain pipe connection part as close to the front surface as possible (close to the inspection lid).

器具側接続部は布基礎天端より上方に突出するように構成し、突出部周囲にモルタルやグラウト等を充填することにより排水ヘッダーを所定の位置に固定することが出来る。特に、床をALC(軽量気泡コンクリート)パネルやPC(プレキャストコンクリート)パネルで構成し、その周囲をモルタルで固定する工法の場合には、モルタルの打設と同時に、配管作業の終了した突出部周囲にもモルタルが充填されて排水ヘッダーも固定できるため、排水ヘッダーの固定作業に掛かる手間を軽減させることが出来る。   The appliance-side connecting portion is configured to protrude upward from the top end of the fabric base, and the drainage header can be fixed at a predetermined position by filling mortar, grout, etc. around the protruding portion. In particular, in the case of a construction method in which the floor is composed of ALC (lightweight aerated concrete) panel or PC (precast concrete) panel and the surrounding area is fixed with mortar, the periphery of the projecting part where the piping work is completed at the same time as the mortar is placed Moreover, since the mortar is filled and the drainage header can be fixed, the labor required for fixing the drainage header can be reduced.

(傾斜面の構成)
器具排水管の内部には、排水と共に流れ込んで来た砂や塵埃が排水ヘッダー内に残留、堆積しないように、排水桝側接続部に向かって傾斜面を形成するのが好ましい。また、傾斜面を形成する勾配部材を排水ヘッダー本体とは別体とすれば、清掃時に勾配部材を取り外して排水ヘッダー内部の空間を広げることが出来、メンテナンス性が損なわれない。
(Configuration of inclined surface)
It is preferable that an inclined surface is formed in the appliance drain pipe so as to prevent the sand and dust flowing in along with the drainage from remaining and accumulating in the drain header. Further, if the gradient member forming the inclined surface is separated from the drainage header main body, the gradient member can be removed during cleaning to widen the space inside the drainage header, and maintainability is not impaired.

(点検蓋の構成)
排水ヘッダーの前面部(建物外部側の面)には、排水ヘッダー内部や排水ヘッダーに接続された排水管の点検、清掃等を目的として開口が設けられるが、排水ヘッダー内を通過する排水の溢出の防止を目的として通常時開口は点検蓋にて閉塞される。
(Configuration of inspection lid)
The front of the drainage header (the surface on the outside of the building) has an opening for the purpose of inspection and cleaning of the drainage pipe connected to the drainage header and inside the drainage header, but overflow of drainage that passes through the drainage header In order to prevent this, the opening is normally closed with an inspection lid.

排水ヘッダー本体と点検蓋とは、水密性を確保するためにゴムパッキン等の止水部材を介してビス等で固定するのが好ましい。   The drain header body and the inspection lid are preferably fixed with screws or the like via a water stop member such as rubber packing in order to ensure water tightness.

排水ヘッダーで処理すべき排水が建物の屋根面やベランダ面への降雨である場合、点検蓋には通気の機能とオーバーフロー水排出の機能とを兼ねた孔を設けるのが好ましい。特に、雨水の排水方式がサイホン式の場合、サイホンの妨げとなる器具排水管内部の空気を当該孔から押し出すことが容易となるため、速やかに排水を開始させることが出来る。   When the drainage to be treated by the drainage header is rainfall on the roof surface or veranda surface of the building, it is preferable that the inspection lid is provided with a hole having both a function of ventilation and a function of discharging overflow water. In particular, when the rainwater drainage method is a siphon type, it becomes easy to push out the air inside the instrument drainage pipe that hinders the siphon from the hole, so that drainage can be started promptly.

尚、処理すべき排水が雑排水の場合、点検蓋に孔を設けると臭気の拡散の問題が生じるので、別途対策が必要である。また、孔は鼠等の小動物が侵入しないような大きさであることが好ましい。また、排水ヘッダー内で跳ねた排水が容易に孔から外へ出ないように、孔には水返しを設けることが好ましい。   In addition, when the wastewater to be treated is miscellaneous wastewater, if a hole is provided in the inspection lid, a problem of odor diffusion occurs. The hole is preferably sized so that small animals such as pupae do not enter. Moreover, it is preferable to provide a water return in the hole so that the waste water splashed in the drain header does not easily go out of the hole.

排水桝側接続部10bには内径が75mm程度の塩化ビニル製パイプからなる排水桝排水管21が接続されている。排水桝排水管21は2つの90度エルボー21aにてU字に屈曲されて布基礎1のスリーブ1bを経由して建物A外部に延設され建物A外部の排水桝に接続されている。排水桝排水管21の排水方式はサイホン式ではない在来の自然流下式である。   A drainage drainage pipe 21 made of a vinyl chloride pipe having an inner diameter of about 75 mm is connected to the drainage side connection part 10b. The drainage drainage pipe 21 is bent into a U shape by two 90-degree elbows 21a, is extended to the outside of the building A via the sleeve 1b of the fabric foundation 1, and is connected to a drainage drainage outside the building A. The drainage method of the drainage drainage pipe 21 is not a siphon type but a conventional natural flow type.

(点検蓋について)
図5に示すように、点検蓋11は排水ヘッダー本体10の開口10cに対応した略長方形である。点検蓋11の上部にはスリット11cが設けられている。点検蓋11の周縁部の裏面には弾力性のある樹脂で構成されたパッキン材11bが貼着されている。図2(e)は図2(d)の丸破線部分の拡大図である。点検蓋11の周縁部に穿たれたビス孔11aと排水ヘッダー本体10の前面部の開口10c周縁のビス孔10eの位置をあわせてビス12を螺入し、パッキン材11bが押し潰されるまで締結することで点検蓋11は排水ヘッダー本体10の前面部に密着固定される。
(About the inspection lid)
As shown in FIG. 5, the inspection lid 11 has a substantially rectangular shape corresponding to the opening 10 c of the drainage header body 10. A slit 11c is provided in the upper part of the inspection lid 11. A packing material 11b made of an elastic resin is attached to the back surface of the peripheral edge of the inspection lid 11. FIG.2 (e) is an enlarged view of the broken line part of FIG.2 (d). Align the screw hole 11a drilled in the peripheral part of the inspection lid 11 with the screw hole 10e in the peripheral part of the opening 10c in the front part of the drainage header body 10, screw in the screw 12, and tighten until the packing material 11b is crushed As a result, the inspection lid 11 is firmly fixed to the front surface of the drainage header body 10.

スリット11cは通気兼オーバーフロー水排出用の孔であり、図2(c)に示すように、点検蓋11の上端寄りで排水桝側接続部10bよりも高い位置に設けられている。また、スリット11cの背後には、図3のように水返し11dを設けているので、器具排水管20から勢い良く流れ込んだ排水が、排水ヘッダー本体10内部で跳ねてもスリット11cから外へ出る虞はない。   The slit 11c is a hole for venting and overflowing water discharge, and is provided near the upper end of the inspection lid 11 and higher than the drainage side connection portion 10b as shown in FIG. Further, since a water return 11d is provided behind the slit 11c as shown in FIG. 3, even if the waste water that has flowed in from the drainage pipe 20 bounces inside the drainage header body 10, it exits from the slit 11c. There is no fear.

図5に示すように、点検蓋11の裏面には、幅方向についてはV字に中央に向かって傾斜し、奥行き方向にも傾斜した傾斜面13aを有する勾配部材13が一体的に取り付けられている。勾配部材13は、排水ヘッダー本体10内部の形状に対応しており、点検蓋11を本体10に固定した状態で、中央先端部の最も低い位置が排水桝側接続部10bの開口10b1に対向し排水を排水桝排水管21方向に案内し得るように構成されている。なお、勾配部材13の周縁部は、パッキン材(不図示)を介して排水ヘッダー本体10の内面へ押し当てられ、傾斜面13aの下側へ排水が回り込むことはない。   As shown in FIG. 5, on the back surface of the inspection lid 11, a gradient member 13 having an inclined surface 13a inclined in a V shape toward the center in the width direction and also inclined in the depth direction is integrally attached. Yes. The gradient member 13 corresponds to the shape inside the drainage header body 10, and with the inspection lid 11 fixed to the body 10, the lowest position of the center tip is opposed to the opening 10 b 1 of the drainage side connection part 10 b. The drainage can be guided in the direction of the drainage / drainage pipe 21. Note that the peripheral edge portion of the gradient member 13 is pressed against the inner surface of the drainage header body 10 via a packing material (not shown), so that the drainage does not flow below the inclined surface 13a.

即ち、図2に示すように、排水ヘッダーBは、器具側接続部10aを排水ヘッダー本体10の上面部に形成すると共に、該排水ヘッダー本体10の内部に排水を排水桝側接続部10b方向に案内する傾斜面13aを形成したものである。   That is, as shown in FIG. 2, the drainage header B forms the appliance side connection portion 10a on the upper surface portion of the drainage header body 10, and drains the drainage header body 10 in the direction of the drainage side connection portion 10b. An inclined surface 13a to be guided is formed.

(効果)
排水ヘッダー本体10内部は勾配部材13が存在するので、雨水に混入した砂塵埃等も排水ヘッダーBの本体10内部に堆積することなくスムーズに排出することが出来る。
(effect)
Since the gradient member 13 is present inside the drainage header body 10, sand dust and the like mixed in the rainwater can be smoothly discharged without accumulating inside the body 10 of the drainage header B.

また、スリット11cによって器具排水管20の端部が大気に開放されるので、ドレインに流れ込んだ雨水が器具排水管20内部の空気を押し出し易くなりサイホンの原理を利用した排水を速やかに開始することが出来る。また、排水桝排水管21が詰まるなどして排水がなされなくなった場合には、スリット11cから排水が建物A外に排出されベランダに雨水が溜まることがない。   In addition, since the end of the instrument drain pipe 20 is opened to the atmosphere by the slit 11c, rainwater flowing into the drain can easily push out the air inside the instrument drain pipe 20, and drainage using the siphon principle can be started quickly. I can do it. Further, when the drainage drainage pipe 21 is clogged and the drainage is not performed, the drainage is not discharged from the building A through the slit 11c, and rainwater does not accumulate on the veranda.

点検、清掃等の際は、点検蓋11を取り外すことによって排水ヘッダー本体10の前面部は全面的に開放され、しかも、点検蓋11と勾配部材13が一体となっており点検蓋11の取り外しと同時に本体内部に作業上の障害物となる勾配部材13が取り除かれるので、作業が行い易い。   During inspection, cleaning, etc., the front part of the drainage header body 10 is completely opened by removing the inspection lid 11, and the inspection lid 11 and the gradient member 13 are integrated to remove the inspection lid 11. At the same time, since the gradient member 13 that is an obstacle to work is removed from the inside of the main body, the work is easy to perform.

また、器具側接続部10a及び排水桝側接続部10bは、排水ヘッダー本体10の開口部の近傍で充分に手の届く範囲に位置し、開口からの目視も可能であるので、点検作業や清掃器具を器具側接続部10aや排水桝側接続部10bから挿入して器具排水管20や排水桝排水管21を清掃する作業を容易に行うことが出来る。   In addition, the appliance side connection part 10a and the drainage side connection part 10b are located within the reach of the drainage header body 10 in the vicinity of the opening and can be seen from the opening. It is possible to easily perform the work of cleaning the appliance drain pipe 20 and the drainage drain pipe 21 by inserting the instrument from the appliance side connection portion 10a and the drainage side connection portion 10b.

図6は、排水管接続部10a,10bの位置に関する他の構成例である。排水ヘッダー本体10が建物A内部方向に延伸されており、器具側接続部10aが排水ヘッダー本体10の背面部に設けられ、排水桝側接続部10bが排水ヘッダー本体10の建物A内部方向に延伸した底面部に設けられている。   FIG. 6 is another configuration example relating to the positions of the drain pipe connection portions 10a and 10b. The drainage header body 10 is extended in the direction of the inside of the building A, the appliance side connection part 10a is provided in the back part of the drainage header body 10, and the drainage side connection part 10b is extended in the direction of the inside of the building A of the drainage header body 10. Provided on the bottom surface.

即ち、本実施形態では、布基礎1から建物A内部側に突出した排水ヘッダー本体10の底面部に排水桝側接続部10bを備えたものであり、このように構成しても前記実施例1と同様の作用効果を奏することが出来る。   That is, in the present embodiment, the drainage header main body 10 that protrudes from the fabric foundation 1 to the inside of the building A is provided with the drainage side connection portion 10b on the bottom surface portion. The same operational effects can be achieved.

本発明の活用例として、複数の排水管からの排水を一系統の排水管に集約して排水する際に使用する排水ヘッダーに適用出来る。   As an application example of the present invention, the present invention can be applied to a drainage header that is used when draining water from a plurality of drainage pipes into a single drainage pipe.
