Description

【0001】
【発明の属する技術分野】
本発明は、合成樹脂製集合ますに関するものである。
【0002】
【従来の技術】
一般に、部材を予め工場生産し、施工現場でこれを組立てる構造、すなわち、プレハブ構造(工業化構造)によって建物のユニット化が行われている。
【0003】
これによると、現場での労務量を減らし、全体の工期を短縮し、設備の整った条件で工場生産することで品質の安定性が得られる、とされている。
【0004】
そのため、屋内給水・給湯については、配管のユニット化が行われているが、屋内排水管についても、ユニット化による合理化を強く要請されている。
【0005】
そこで、屋内排水管のユニット化(プレハブ配管ともいう)について、各種の提案が行われている(例えば特開平4−368523号公報、特開平5−156675号公報、特開平7−71676号公報、特開2001−40745号公報、特開2001−220792号公報等参照)。
【0006】
例えば、前掲の特開2001−40745号公報には、流し台、洗面台、浴槽、洗濯機(これらを雑排器具ともいう)等の排水を、屋外に排出するため、家屋の床と基礎コンクリ−トであるスラブ面との懐空間に、その内部を点検する点検口と、排水を排出する流出口と、排水が前記流し台等から流入する流入口と、を設けたます本体を設け、前記点検口を密閉する蓋を設け、前記流出口に接続され、排水を屋外に排出する1本の排出主管を設け、前記流し台等と流入口とを、可撓管からなる排水枝管で接続した集合ますからなる屋内の床下配管が紹介されている。
【0007】
そして、かかる床下配管における排水枝管を、予め生産工場等で切断加工して流入口に接続した後、施工現場に搬入して布設すると、床下配管の位置決め等を省略し、工期を大幅に短縮すると共に、人件費を節約し、更に施工現場での水密性の試験を省略でき、その上、極めて信頼性の高い商品にすることができる、とされている。
【0008】
ところが、かかる床下配管の集合ますでは、その底部にインバ−トを形成していても、流入する排水の流速が速いと、一方の流入口から流入した排水が他方の流入口に逆流し、特に排水中に固形物が含まれていると、他方の流入口に堆積するおそれがあり、そのため、流入した排水をスム−ズに流すため仕切板を、仮に設けても、仕切板のところで排水の通路が狭くなっているため排水の流速が遅いと、前記固形物の滞留が発生しやすい、という問題が考えられる。
【0009】
一方、かかる問題を解決しようとする一般の宅内排水ますが、次のように提案されている(特開平11−280137号公報参照)。
【0010】
すなわち、流入口から流入する排水の状況に応じて、他の流入口へ逆流を防止し、かつ、排水ます内部の詰まりを防止する仕切板を着脱自在に設けて、流入口から流出口への流れ方向を変化させるようにした宅内排水ますが提案されている。
【0011】
【発明が解決しようとする課題】
しかしながら、かかる着脱自在の仕切板付の宅内排水ますは、その排水枝管の一つがトイレに接続されたり、また、他の一つが階上の排水管に接続されたりして、その固形物が汚物であったり、流れの流速が極めて速い、という排水の状況に使用されるため、これらの条件を異にする床下配管における集合ますには適用できない、という問題が考えられる。
【0012】
しかも、かかる宅内排水ますでは長寸の点検筒を用いているので、床とスラブ面との懐空間(高さ約400〜600mm)には適用できない、という問題がある。
【0013】
そこで本発明は、かかる諸問題を一掃することを主たる目的とし、床下配管における集合ますの高さを可及的に低くすることを副たる目的とするものである。
【0014】
【課題を解決するための手段】
本発明は、かかる目的を達成するため、本発明は、1)ます本体に1つの流出口と複数の流入口とをもち、かつ、該ます本体の上向き嵌合口で蓋により閉塞した床下配管等の合成樹脂製集合ますにおいて、前記複数の流入口のます本体内の開口側を上下方向の放射状仕切板と、該仕切板の隣同士に亘る逆L字状天板とで区画して仕切体を構成し、該仕切体を、前記蓋に設けることにより、前記天板により前記開口部を庇状に覆って排水を良好にガイドすると共に、該集合ますの高さを低くするようにしたことを特徴とする床下配管等の合成樹脂製集合ますにあり、また、2)ます本体に1つの流出口と複数の流入口とをもち、これらの流入口と流出口との間に段差を設けたインバ−ト部を形成し、かつ、該ます本体の上向き嵌合口で蓋により閉塞した床下配管等の段差付合成樹脂製集合ますにおいて、前記複数の流入口のます本体内の開口側を上下方向の放射状仕切板と、該仕切板の隣同士に亘る逆L字状天板とで区画して仕切体を構成し、該仕切体を前記蓋に設けることにより、前記段差を確保しながら区画して、前記天板により前記開口部を庇状に覆って排水を良好にガイドすると共に、該集合ますの高さを低くするようにしたことを特徴とする床下配管等の合成樹脂製集合ますにあり、また、3)前記集合ますをドロップますに適用した請求項1に記載の合成樹脂製集合ますにあり、また、4)前記集合ますを床下配管用集合一括排水設備の集合ますに適用した請求項2に記載の合成樹脂製集合ますにあり、また、5)前記仕切板と天板とを前記蓋下面に吊設した上下方向の軸に設けた請求項1から4に記載の合成樹脂製集合ますを要旨とするものである。
【0015】
【発明の実施の形態】
本発明を図面に示す実施例により詳細に述べる。
【0016】
図1は本発明の実施例の全体図、図2は図1の要部外観図、図3は図2の縦断面図、図4は図2の一部(蓋)省略平面図、図5は図3の要部変形図で、図5(A)は平面図、図5(B)は図5(A)の側面図、図6は図5の底面図(A)と、図6(A)におけるa矢視断面図(B)とを示し、図7は図3の変形例断面図を示す。
【0017】
本発明の実施例の屋内排水用のユニット化した床下配管、すなわち、集合一括排水設備1は、木造戸建住宅に好適であるが、小規模集合住宅にも適用できるものである。
【0018】
なお、本明細書における木造には、在来軸組み木造工法、ツ−バイフォ−工法、集成材による大断面木造等が含まれる。
【0019】
勿論、本実施例は、鉄骨ユニット工法による戸建住宅にも適用できる。
【0020】
先ず、この集合一括排水設備1の概要を述べる。図1において、例えば、木造家屋2を建設するには敷地に根切り等を施し、ベ−スとなるフ−チングや布基礎4′等の基礎工事を、排水主管用スリ−ブ等の手当をしてから行う。
【0021】
この基礎工事のコンクリ−トの養生後、床下全面に防湿コンクリ−ト3を打設する。この防湿コンクリ−ト打設時には、後記のアンカ−ボルト19をそのコンクリ−ト内に埋設する。
【0022】
この防湿コンクリ−ト3の養生後、集合ます4をアンカ−止め等により取外し自在に固定・載置すると共に、1本の排水主管5を布設してこの集合ます4と接続する。その後、本体工事を行い、次いで内部工事に伴って2次の屋内配管を行う。
【0023】
すなわち、例えば、台所の内部工事を行えば、その流し台と集合ます4とを、可撓管を用いた排水枝管6で雑排器具接続用ソケット7によりワンタッチ式に接続する。
【0024】
この排水枝管6の長さは、施工図面によって予め判明した長さに切管しており、したがって、接続するだけで所定の流れ勾配が得られるものである。
【0025】
同様に、洗面台、洗濯機および浴槽を設置する内部工事毎に、それぞれ排水枝管6を既設の集合ます4と接続する。
【0026】
この集合ます4は、木造家屋2の床8下の懐空間に載置しており、その真上の床8には不図示の点検口を開閉自在に設け、集合ます4の保守点検を行うようにしている。なお、図1中、9は根太を示す。
【0027】
以上のような戸建住宅用等の屋内排水用の集合一括排水設備1の工法であるから、施工精度が向上し、コンクリ−ト工事業者等の多能工でも充分に配管することができ、施工のタイムラグを防ぎながら、施工に伴う人件費(配管施工費の約7割を占めるもの)を節減することができ、しかも、屋外の宅内排水ますの数も節減することができる。
【0028】
次に、以上のような屋内排水用の集合一括排水設備1における集合ます4を詳細に述べる。
【0029】
先ず、この集合ます4の概要を述べる。主として、図2および図3において、この集合ます4は、平面視で円形(勿論4方形でも可)のいわゆる合成樹脂(塩ビ射出成形)製合流段差付ますで構成し、放射状ないし、排水主管5の管軸に対し平行および直交に多数の排水枝管6が接続できるようにしている。
【0030】
すなわち、このます本体10には横向きに、1つの比較的大口径(例えば100mmφ)の排水主管用接続口(具体的にはゴム輪受口であるが、流出口とも表現する)11と、複数(4個)の比較的小口径(例えば60mmφ)の排水枝管用接続口(具体的にはワンタッチ式接続口であるが、流入口とも表現する)12,12…とを各一体突設し、これらの排水主管用接続口11と排水枝管用接続口12との間に段差(例えば55mm)Sを設けたインバ−ト部13を形成している。
【0031】
また、この寸胴状になったます本体10には、上向きに大口径(例えば200mmφ)の蓋用嵌合口14を形成し、この蓋用嵌合口14には仕切体17付の蓋15が着脱自在に、リップ状パッキン16を介して完全密閉して、下水臭を屋内に漏らさないようにしている。
【0032】
そして、前記のように複数の排水枝管用接続口12を設けて、屋内の各種の雑排器具からの排水が流入しても、後記詳細の仕切体17と、比較的大きくとった段差Sとによって、他の排水枝管6へ逆流しないようにしている。
【0033】
また、このます本体10の下部には、図2および図4で示すようにアンカ−ボルト用フランジ18を形成し、このフランジ18に、防湿コンクリ−ト3に打込まれた複数のアンカ−ボルト19,19を係合し、このます本体10を防湿コンクリ−ト3に載置して固定し、床下配管作業をきわめて容易にしている。
【0034】
なお、前記排水主管5は、防湿コンクリ−ト3で固定された支持金具20により支持されて防湿コンクリ−ト3上で配管し、エルボ21を介して防湿コンクリ−ト3や布基礎4′を貫通して屋外のトラップます(不図示)に接続するようにしている。
【0035】
ここにおいて、このます本体10には、排水主管用接続口11側を除く3方側に、各2つの平行になった排水枝管用接続口12を予め形成したので、略同一面上に計6個の流入用接続口(12)が形成でき、集合ます4の高さを低くする配管に好都合とすると共に、各種の雑排器具の数に不足なく、また、同一方向からの接続を容易にすることができる。しかも、2個平行流入になるので、ます本体10内での互いの流水による撥ね返りを防ぐことができる。なお、不要な接続口(12)は閉栓する。
【0036】
殊に、このます本体10を射出成形製にすれば、成形用金型の型じめ型割りが容易にでき、ひいては、射出成形用金型や成形機を複雑化せず、生産性を向上する。
【0037】
次に、前記仕切体17について述べる。図3、図5および図 6において、この仕切体17は、ます本体10に設けた複数の排水枝管用接続口12,12…を各区画する垂直状にした8枚の放射状仕切板22と、ます本体10に設けた比較的大きい段差Sを、利用して排水主管用接続口11へ迅速且つ円滑に流出させると共に、排水の撥ね上げを防止する、前記仕切板22の隣同志に亘る逆L字状天板23と、から構成している。
【0038】
勿論、前記放射状仕切板22は、前記排水枝管用接続口12をそれぞれ区画するものに限らず、2つの接続口12,12をまとめて区画するものでもよい。したがって、この場合、仕切板22は4枚ですむ。
【0039】
そのため、放射状仕切板22によって、排水が流入しないときの他の流入口(12)へ逆流を防止したり、排水が同時に流入して衝突による撥ね上げ・飛び散りを防止したり、殊に、上向きラッパ体25の一部で構成する逆L字状天板23によって、比較的大きくとった段差Sを利用して迅速に流出させ、ひいては、ます本体10の高さを可及的に抑えることができ、限られた懐空間での床下配管に好都合にすることができる。
【0040】
その結果、防湿コンクリ−ト3等にピット等を形成せず、打設工事を簡易にすることができる。
【0041】
これらの放射状仕切板22や逆L字状天板23は、中心軸(上下方向にした軸)24と一体射出成形している。
【0042】
すなわち、パイプ状中心軸24の下部に、上向きラッパ体25の最小径部が、特に図6(B)に示すように、一体になっており、また、この上向きラッパ体25を、特に図5(B)に示すように、四辺形の仕切板22,22によって垂直方向に且つ中心軸24を中心とする放射状に等間隔で区画するように一体成形している。
【0043】
この上向きラッパ体25は、特に図5(A)で示すように、平面視で円板状になっていて、その最大径より仕切板22が突出している(図3では突出していない)。
【0044】
この上向きラッパ体25の一部で構成する逆L字状天板23は、図3に示すように、排水枝管用接続口12のます本体10における内側開口部を庇状に覆って排水を良好にガイドしている。
【0045】
また、前記中心軸24の下端とその下端が略一致する放射状仕切板22は、図3に示すように、段差Sの高さに略一致させていて、放射状になってその基部が絞られた仕切板22であっても、排水の滞留を防ぎ、直ちに段差Sへ流下させるようにしている。
【0046】
また、放射状仕切板22や逆L字状天板23が一体成形されている中心軸24は、蓋15の下面中央部で組付一体化し(図3では組付構造を省略)、蓋15を取外すと、仕切体17をます本体10から取出すことができ、ます本体10を含めた床下配管の保守点検掃除が容易にできる。
【0047】
この蓋15と中心軸24とを一体化するには、次のようにしている。図7および図6(B)に示すように、蓋15の下面中央に短軸30を一体にして突設し、この短軸30の下端に、左右1対の逆止爪付弾性片29と、これらの弾性片29と直交する方向に1つのキ−28をそれぞれ軸方向に延設する。
【0048】
一方、前記中心軸24には、そのパイプの上端から軸方向の切欠部25′を設けると共に、上端に狭窄状係止部28を設け、この切欠部25′に前記キ−28を嵌合して蓋15と中心軸24との回り止めにし、また、前記1対の弾性片29を、樹脂変形させて、この狭窄状係止部28を超え、その爪を狭窄状係止部28に係合させて抜け止めにして、総じて、ガッチリと一体的に組付ける。
【0049】
したがって、仕切体17と蓋15とは別体にして、その合成樹脂射出成形を容易にしている。
【0050】
ここにおいて、前記切欠部25′を若干長寸に形成したので、キ−28を嵌合しても、下方開口のパイプ状中心軸24は、パイプ内外と連通するようになっている。
【0051】
そのため、この切欠部25′が環流口となって、流入口(12)の1つから満管流で排水が流入すると、集合ます4内に真空を形成するおそれがあって、他の流入口12の上流側のトラップ(封水)を破壊しやすいので、集合ます4内の空気を、図7のC矢印(また はC矢印逆方向)のように、ます本体10内を環流させ、この真空を防いでいる。
【0052】
勿論、蓋15と仕切体17とを一体化せず、仕切体17の放射状仕切板22の上下方向の外端部を、ます本体10の内面に突設した上下方向の2突条による嵌合溝に嵌合させて、仕切体17を組付けてもよい。
【0053】
なお、図2および図4中、26はます本体10の上縁に一体形成突設した1対の係止鉤であって、この係止鉤26に蓋15のフランジをバヨネット結合により着脱自在に取付ける。
【0054】
なお、本実施例の集合ます(会所ます)は、床下配管における集合一括排水設備に用いるが、本発明はこれに限らず、他の一般の宅内排水ますにも適用することができ、更に、流出口が下向きになったドロップますにも適用することができる。
【0055】
【発明の効果】
本発明によると、放射状仕切板と天板とで、複数の流入口の各開口部または2つの開口部を区画したので、他の流入口へ排水の逆流を防止できるのは勿論、排水同志の衝突により撥ね上がりや飛び散りを防止することができることから、1つの集合ますに多数の流入口を設けることができ、ひいては、床下配管等のユニット化に好都合にすることができる。
【0056】
殊に、仕切板と天板とによる仕切体をます本体に内装したので、あたかも、流入口から独立した管路が多数束ねて形成でき、ひいては、ます本体をコンパクトにし、いわゆるヘッダ−タイプの集合路の高さと同様になり、したがって、ます本体の高さを低くすることができる。
【0057】
更に、流出側を除く3方それぞれに、2つの流入口を略同一平面上に設けたので、多数の流入口を設けても、ます本体の高さを低くすることができる。
【0058】
勿論、排水主管の軸方向に長尺のヘッダ−タイプの集合ますに比べ、設置場所をとらず床下配管に好都合となる。

BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin assembly.
[0002]
[Prior art]
Generally, a building is unitized by a structure in which members are produced in advance and assembled at a construction site, that is, a prefabricated structure (industrialized structure).
[0003]
According to this, it is said that the stability of the quality can be obtained by reducing the amount of labor at the site, shortening the entire construction period, and producing in a factory under well-equipped conditions.
[0004]
For this reason, pipes are unitized for indoor water supply and hot water supply, but rationalization by unitization is also strongly demanded for indoor drain pipes.
[0005]
Therefore, various proposals have been made on the unitization of indoor drain pipes (also referred to as prefabricated pipes) (for example, JP-A-4-368523, JP-A-5-156675, JP-A-7-71676, JP, 2001-40745, JP, 2001-220792, etc.).
[0006]
For example, the above-mentioned Japanese Patent Application Laid-Open No. 2001-40745 discloses that the drainage of a sink, a sink, a bathtub, a washing machine (these are also referred to as miscellaneous drainage devices) and the like are discharged to the outside. In the pocket space with the slab surface, the main body is provided with an inspection port for inspecting the interior, an outlet for discharging wastewater, and an inlet for draining water from the sink, etc. An assembly in which a lid for sealing the mouth is provided, connected to the outlet, provided with one discharge main pipe for discharging waste water to the outdoors, and the sink and the inlet are connected by a drain branch pipe made of a flexible pipe In-house underfloor piping is introduced.
[0007]
And when the drainage branch pipe in such underfloor piping is cut and processed in advance at the production factory etc. and connected to the inflow port, it is carried into the construction site and installed, so positioning of the underfloor piping is omitted, and the construction period is greatly shortened In addition, it is said that labor costs can be saved, water-tightness testing at the construction site can be omitted, and the product can be made extremely reliable.
[0008]
However, in such a collection of underfloor pipes, even if an inverter is formed at the bottom of the pipe, if the flow rate of the inflowing wastewater is high, the wastewater flowing in from one inflow port will flow backward to the other inflow port, If solid matter is contained in the drainage, there is a risk of accumulation at the other inflow port.Therefore, even if a partition plate is provided to allow the inflowing wastewater to flow smoothly, Since the passage is narrow, if the flow rate of drainage is slow, there is a problem that the solid matter tends to stay.
[0009]
On the other hand, a general household wastewater which attempts to solve such a problem has been proposed as follows (see Japanese Patent Application Laid-Open No. 11-280137).
[0010]
In other words, depending on the situation of drainage flowing in from the inlet, a partition plate that prevents backflow to other inlets and prevents clogging of the drainage drainage is detachably provided. It has been proposed that the drainage in the house is designed to change the flow direction.
[0011]
[Problems to be solved by the invention]
However, in the drainage with a removable partition plate, one of the drain branch pipes is connected to the toilet and the other is connected to the drain pipe on the floor, so that the solid matter is filth. Or because it is used in the situation of drainage where the flow velocity of the flow is extremely high, there is a problem that it cannot be applied to the gathering in the underfloor piping having different conditions.
[0012]
In addition, since such a household drainage basin uses a long inspection cylinder, there is a problem that it cannot be applied to the pocket space (height of about 400 to 600 mm) between the floor and the slab surface.
[0013]
Therefore, the main object of the present invention is to eliminate such problems, and the secondary object is to make the height of the aggregate in the underfloor piping as low as possible.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides: 1) an underfloor pipe that has one outflow port and a plurality of inflow ports in the main body, and is closed by a lid at the upper upward fitting port of the main body. In the assembly made of synthetic resin, the opening side in the main body of the plurality of inlets is partitioned by a vertical radial partition plate and an inverted L-shaped top plate adjacent to the partition plate. And the partition is provided on the lid so that the opening is covered in a bowl shape with the top plate to guide the drainage well and the height of the assembly is reduced. 2) The main body has one outlet and multiple inlets, and there is a step between these inlets and outlets. The upper part of the main body is formed with a lid at the upward fitting port. In the assembly of stepped synthetic resin such as underfloor piping, the opening side in the main body of the plurality of inlets is a radial partition plate in the vertical direction, and an inverted L-shaped top plate adjacent to the partition plate. The partition is provided with the lid, and the partition is provided while the step is secured, and the opening is covered in a bowl shape by the top plate to guide the drainage well. 2. The assembly according to claim 1, wherein the assembly is made of synthetic resin, such as underfloor piping, characterized by lowering the height of the assembly, and 3) applied to the assembly drop. 4) The synthetic resin assembly according to claim 2 applied to a collective drainage assembly for underfloor piping, and 5) the partition. A plate and a top plate are suspended in the vertical direction of the lid. Plastic collection masu according to claims 1 to 4 provided on the one in which the subject matter.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
The invention will be described in more detail by means of an embodiment shown in the drawing.
[0016]

FIG. 5 (A) is a plan view, FIG. 5 (B) is a side view of FIG. 5 (A), FIG. 6 is a bottom view (A) of FIG. FIG. 7A is a cross-sectional view (B) taken along arrow a in FIG.
[0017]
The unitized underfloor pipe for indoor drainage according to the embodiment of the present invention, that is, the collective collective drainage facility 1 is suitable for a wooden detached house, but can also be applied to a small-scale apartment house.
[0018]
In addition, the wooden structure in this specification includes a conventional shaft-framed wooden construction method, a two-by-four construction method, a large-section wooden construction using laminated wood, and the like.
[0019]
Of course, the present embodiment can also be applied to a detached house by a steel frame unit method.
[0020]
First, an outline of the collective collective drainage facility 1 will be described. In FIG. 1, for example, in order to construct a wooden house 2, the site is rooted and the foundation work such as a base footing and a cloth foundation 4 ′ is provided, such as a drain main pipe sleeve. Do it after doing.
[0021]
After curing the concrete for the foundation work, a moisture-proof concrete 3 is placed over the entire floor. At the time of placing the moisture-proof concrete, an anchor bolt 19 which will be described later is buried in the concrete.
[0022]
After the moisture-proof concrete 3 is cured, the assembly 4 is fixed and placed detachably by anchoring or the like, and one drain main pipe 5 is laid and connected to the assembly 4. After that, main body construction is performed, and then secondary indoor piping is performed along with the internal construction.
[0023]
That is, for example, when the interior work of the kitchen is performed, the sink and the set 4 are connected to the drainage branch pipe 6 using a flexible pipe in a one-touch manner by the miscellaneous equipment connecting socket 7.
[0024]
The length of the drainage branch pipe 6 is cut to a length previously determined from the construction drawing. Therefore, a predetermined flow gradient can be obtained only by connecting.
[0025]
Similarly, the drainage branch pipe 6 is connected to the existing collective mass 4 for each internal work for installing the wash basin, the washing machine, and the bathtub.
[0026]
This set 4 is placed in the pocket space under the floor 8 of the wooden house 2, and an inspection port (not shown) is provided on the floor 8 directly above it so that it can be opened and closed. I am doing so. In FIG. 1, 9 indicates joists.
[0027]
Since it is a construction method of collective drainage 1 for indoor drainage such as for detached houses as described above, construction accuracy is improved, and multi-purpose workers such as concrete construction contractors can sufficiently pipe, While preventing the construction time lag, labor costs associated with construction (which accounts for about 70% of piping construction costs) can be reduced, and the number of outdoor household wastewater can be reduced.
[0028]
Next, the collective mass 4 in the collective collective drainage equipment 1 for indoor drainage as described above will be described in detail.
[0029]
First, the outline of this set 4 will be described. 2 and 3, this assembly 4 is constituted by a so-called synthetic resin (vinyl chloride injection molding) confluence step formed in a circular shape (of course, can be a quadrilateral shape) in a plan view. A number of drainage branch pipes 6 can be connected in parallel and perpendicular to the pipe axis.
[0030]
That is, the main body 10 has a relatively large diameter (for example, 100 mmφ) drain main pipe connection port (specifically, a rubber ring receiving port but also expressed as an outflow port) 11 and a plurality of the main body 10 in a horizontal direction. (4) relatively small-diameter (for example, 60 mmφ) drainage branch connection ports (specifically, one-touch connection ports, but also expressed as inflow ports) 12, 12. An invert portion 13 having a step (for example, 55 mm) S is formed between the drain main pipe connection port 11 and the drain branch port connection port 12.
[0031]
In addition, a lid fitting port 14 having a large diameter (for example, 200 mmφ) is formed upward on the main body 10 in the form of a cylindrical body, and a lid 15 with a partition 17 is detachably attached to the lid fitting port 14. In addition, the sewage odor is prevented from leaking indoors by completely sealing through the lip packing 16.
[0032]
And even if the drainage from various indoor drainage devices flows in by providing a plurality of drainage branch connection ports 12 as described above, the details of the partition 17 and a relatively large step S will be described later. Therefore, it does not flow back to the other drainage branch pipe 6.
[0033]
Further, as shown in FIGS. 2 and 4, an anchor bolt flange 18 is formed at the lower portion of the main body 10, and a plurality of anchor bolts driven into the moisture-proof concrete 3 are formed on the flange 18. 19 and 19 are engaged, and the main body 10 is placed and fixed on the moisture-proof concrete 3 to facilitate underfloor piping work.
[0034]
The drainage main pipe 5 is supported by a support fitting 20 fixed by a moisture-proof concrete 3 and piped on the moisture-proof concrete 3, and the moisture-proof concrete 3 and the fabric foundation 4 ′ are connected via an elbow 21. It penetrates and connects to an outdoor trap (not shown).
[0035]
Here, in this main body 10, two parallel drainage branch connection ports 12 are formed in advance on three sides other than the drainage main pipe connection port 11 side. A single inflow connection port (12) can be formed, which is convenient for piping that lowers the height of the assembly 4 and that there are not enough deficiencies in various types of miscellaneous drainage devices, and it is easy to connect from the same direction. can do. Moreover, since the two parallel inflows, it is possible to prevent rebound due to mutual flowing water in the main body 10. The unnecessary connection port (12) is closed.
[0036]
In particular, if the main body 10 is made of injection molding, it is easy to squeeze the mold for molding, and the productivity is improved without complicating the injection mold and molding machine. To do.
[0037]
Next, the partition body 17 will be described. 3, 5, and 6, the partition body 17 includes eight radial partition plates 22 each having a plurality of drain branch pipe connection ports 12, 12. A relatively large step S provided in the main body 10 is used to quickly and smoothly flow out to the drain main pipe connection port 11 and to prevent the drainage from splashing up. And a character-shaped top plate 23.
[0038]
Of course, the radial partition plate 22 is not limited to partitioning the drainage branch pipe connection port 12, but may also partition the two connection ports 12 and 12 together. Therefore, in this case, four partition plates 22 are sufficient.
[0039]
For this reason, the radial partition plate 22 prevents backflow to the other inlet (12) when drainage does not flow in, prevents drainage from flowing simultaneously and prevents splashing and scattering due to collision, and in particular, an upward wrapper. The inverted L-shaped top plate 23 formed by a part of the body 25 can be quickly drained by using the relatively large step S, and as a result, the height of the main body 10 can be suppressed as much as possible. Can be convenient for underfloor piping in limited pocket space.
[0040]
As a result, no pits or the like are formed in the moisture-proof concrete 3 or the like, and the placing work can be simplified.
[0041]
The radial partition plate 22 and the inverted L-shaped top plate 23 are integrally injection-molded with a central axis (a vertical axis) 24.
[0042]
That is, the minimum diameter portion of the upward trumpet body 25 is integrated with the lower portion of the pipe-shaped central shaft 24 as shown in FIG. 6B. As shown in (B), the four-way partition plates 22 and 22 are integrally formed so as to be partitioned at equal intervals in the vertical direction and radially about the central axis 24.
[0043]
As shown particularly in FIG. 5A, the upward trumpet body 25 has a disk shape in plan view, and the partition plate 22 projects from its maximum diameter (not projected in FIG. 3).
[0044]
As shown in FIG. 3, the inverted L-shaped top plate 23 formed of a part of the upward trumpet body 25 covers the inner opening of the main body 10 of the drainage branch pipe connection port 12 in a bowl shape so that drainage is good. To guide.
[0045]
Further, the radial partition plate 22 in which the lower end of the central shaft 24 and the lower end thereof substantially coincide with each other is substantially coincident with the height of the step S as shown in FIG. Even the partition plate 22 prevents the stagnation of drainage and immediately flows down to the step S.
[0046]
Further, the central shaft 24 on which the radial partition plate 22 and the inverted L-shaped top plate 23 are integrally formed is assembled and integrated at the center of the lower surface of the lid 15 (the assembly structure is omitted in FIG. 3). When it is removed, the partition 17 can be removed from the main body 10 and maintenance and cleaning of the underfloor piping including the main body 10 can be facilitated.
[0047]
The lid 15 and the central shaft 24 are integrated as follows. As shown in FIG. 7 and FIG. 6B, a short shaft 30 is integrally projected at the center of the lower surface of the lid 15, and a pair of left and right elastic pieces 29 with check pawls are formed at the lower end of the short shaft 30. One key 28 extends in the axial direction in a direction orthogonal to these elastic pieces 29.
[0048]
On the other hand, the central shaft 24 is provided with a notch 25 'in the axial direction from the upper end of the pipe, and a constricted locking portion 28 is provided at the upper end, and the key 28 is fitted into the notch 25'. The lid 15 and the central shaft 24 are prevented from rotating, and the pair of elastic pieces 29 are deformed by resin so as to exceed the constricted locking portion 28 and engage the claw with the constricted locking portion 28. Combine them together to prevent them from coming off, and as a whole, assemble them as a single unit.
[0049]
Therefore, the partition 17 and the lid 15 are separated from each other to facilitate the synthetic resin injection molding.
[0050]
Here, since the notch 25 'is formed to be slightly long, the pipe-shaped central shaft 24 of the lower opening communicates with the inside and outside of the pipe even when the key 28 is fitted.
[0051]
For this reason, if this notch 25 'becomes a reflux port and drainage flows in from a full flow from one of the inlets (12), there is a risk of forming a vacuum in the assembly 4 and other inlets. Since the trap (sealed water) on the upstream side of 12 is easily destroyed, the air in the assembly 4 is circulated in the main body 10 as indicated by the arrow C in FIG. 7 (or the reverse direction of the arrow C). Prevents vacuum.
[0052]
Of course, the lid 15 and the partitioning body 17 are not integrated, but the vertical outer end of the radial partition plate 22 of the partitioning body 17 is fitted by two vertical protrusions protruding from the inner surface of the main body 10. The partition body 17 may be assembled by being fitted in the groove.
[0053]
2 and 4, reference numeral 26 denotes a pair of locking rods integrally formed on the upper edge of the main body 10, and the flange of the lid 15 is detachably attached to the locking rods 26 by bayonet coupling. Install.
[0054]
In addition, although the collective of this example (meeting house) is used for collective collective drainage equipment in underfloor piping, the present invention is not limited to this, and can be applied to other general residential drainage. It can also be applied to drop drops with the outlet facing down.
[0055]
【The invention's effect】
According to the present invention, since each opening or two openings of the plurality of inlets are partitioned by the radial partition plate and the top plate, it is possible to prevent the backflow of drainage to other inlets. Since splashing and scattering can be prevented by collision, a large number of inlets can be provided in a single assembly, which can be convenient for unitization of underfloor piping.
[0056]
In particular, since a partition body made up of a partition plate and a top plate is further installed in the main body, it is possible to form many bundles independent of the inflow port, thereby making the main body more compact and so-called header-type assembly. It becomes the same as the height of the road, and therefore the height of the main body can be made lower.
[0057]
Furthermore, since the two inlets are provided on substantially the same plane in each of the three sides except the outflow side, the height of the main body can be further reduced even if a large number of inlets are provided.
[0058]
Of course, it is convenient for under-floor piping as compared to a header type that is long in the axial direction of the drainage main pipe without taking a place for installation.
