Description

【0001】
【発明の属する技術分野】
本発明は、特に宅内の建屋基礎近傍に設置可能の合成樹脂製排水ます、更に詳しくは省スペ−ス用宅内設置の排水ますに関するものである。
【0002】
【従来の技術】
現在、1つの集合ます、または、1つのヘッダ−型継手を用いた排水用床下配管設備が盛んに提唱されている(例えば、特開2001−220796号公報や本出願人に係る特開2002−327474号公報等参照)。
【0003】
かかる排水用床下配管設備によると、1)排水管のユニット化ができ、現場での労務量を減らす等の効果があり、2)集合ますを用いた場合、これが一種の空気アキュムレ−タとして働き、上流側の器具トラップの破封を低下させる、3)床下配管を非埋設にすると、土工費を節減する、4)屋外の排水ますや排水枝管の数を節減する、等の効果が期待できる、とされている。
【0004】
かかる1つのヘッダ−型継手を用いた床下配管設備について、前掲の特開2001−220796号公報に基づき更に述べる。
【0005】
図7において、これは戸建住宅等の建屋2の床8下の防湿コンクリ−ト3に設けている。
【0006】
この床下配管設備1Bの下流側は、建屋2の布基礎24を貫通して、90度大曲りY継手101、縦短管102、90度エルボ103および横短管104を介して、屋外で埋設されている排水ます105に接続している。
【0007】
この排水桝105は、敷地内に埋設された屋外排水主管106に接続され、この屋外排水主管106は不図示の公共ますに接続している。
【0008】
ところで、かかる床下配管設備1Bは、床下ではヘッダ−型継手107と屋内排水主管5とから構成し、この1つのヘッダ−型継手107には、不図示の水洗トイレ、洗面所、洗濯機、浴室、台所等の各種の雑排水器具に接続している各排水枝管端が接続されている。勿論、これらの器具には器具トラップが付設している。
【0009】
そのため、これらの全ての器具トラップの破封を防ぐため、ヘッダ−型継手107には、屋外で開口された通気管109を取付け、この通気管109によりヘッダ−型継手107や屋内排水主管5内で発生する負圧を防ぎ、前記器具トラップの全部の破封を防いでいる。
【0010】
すなわち、ヘッダ−型継手107には1つの通気管109を設けることから、各種の雑排水器具に対応した数の通気管を設けなくても、これらの器具トラップの封水を有効に維持できるので、材料費や施工費等を節減できる、とされている。
【0011】
一方、かかる一括集中に用いられる屋外排水ます(トイレ用を別にしても2つ)105の埋設深さは、不図示の公共ますの深さが条例等で略決められ、かつ、屋外排水主管106の勾配が決められていること、また、屋外排水主管106の最小土被りについても条例等で20cmと決められていることから、前記のように90度大曲りY継手101、縦短管102、90度エルボ103および横短管104を用いて段差接合構造(落差構造ともいう。以下同じ)110を形成し、その深さが得られるようにしている。
【0012】
【発明が解決しようとする課題】
しかしながら、かかる一括集中に用いられる屋外排水ます105では、前記のような段差接合構造110を形成しているので、部品点数を多くし、一括集中排水の特長の一つである部品点数の節減にとって好ましくないのは勿論、それだけ設置スペ−スをとり狭小地では好ましくない。
【0013】
なお、狭小地に使用可能の小口径ますに関し、実用新案登録第2554325号公報や実開平3−93890号公報等で各種の提案が知られている。
【0014】
この実開平3−93890号公報で示された提案について述べる。
【0015】
これは、主軸上に上下流1対の接続部を設け、かつ、該主軸に直交して地表側に点検筒用接続部を設けたます本体に、垂直管を介して、上方(例えば階上)の排水を合流させる屋外の排水ますにおいて、前記ます本体に、前記垂直管を接続するためのエルボ体を水平状に一体的に取付けることにより、ます本体と垂直管との距離を短くして、狭小地でも使用できるようにした排水ますの提案である。
【0016】
しかしながら、この提案では次のような問題があるので採用できない。
【0017】
▲1▼この提案の屋外排水ますを極狭小地に使用してみると、ます本体からエルボ体が水平状に突出し、これに垂直管(図7中符号102に相当のもの)が立上っているので、それだけ設置スペ−スを占め、尚使用困難となる。
【0018】
▲2▼この垂直管に上方の排水を流入させるには第2のエルボ(図7中符号103に相当するもの)を必要とする。
【0019】
そこで本発明は、かかる諸問題を解決しようとして創作されたものであり、殊に、発想を転換し、工事の施工法を変更することに着眼したり、また、排水ますの水平状流入管に土かぶりを施さないか、薄く施すような屋外の排水ますに着眼し創作された。
【0020】
【課題を解決するための手段】
そのため、本発明は、1)点検筒とインバ−トとからなる排水ますにおいて、該排水ますの上部に流入口を設け、該流入口と前記インバ−ト流出口とを、Uタ−ン状の流れにするような案内部材を内臓したことを特徴とする宅内設置の排水ますにあり、また、2)点検筒部材と、これと別体のインバ−ト部材と、からなる排水ますにおいて、前記点検筒部材に流入口たる水平状流入管用接続部を一体成形して突出させ、該管頂を、該点検筒部材の開閉蓋に略一致させたことを特徴とする宅内設置の排水ますにあり、また、3)点検筒部材と、これと別体のインバ−ト部材と、からなる排水ますにおいて、前記点検筒部材に流入口たる水平状流入管用接続部を一体成形して突出させ、その管頂を地表に略位置させたことを特徴とする建屋基礎近傍に設置可能の塩ビ射出成形製排水ますにあり、また、4)前記接続部と前記インバ−トとを結ぶような流れの下向き案内部材を着脱自在に内臓した請求項2または3に記載の排水ますにあり、また、5)前記流れの下向き案内部材を流入管用接続部の数に合せた曲面をもつようにした請求項4に記載の排水ますにあり、また、6)前記流れの下向き案内部材を、エルボとUタ−ン助勢部材とで構成した請求項4に記載の排水ますにあり、また、7)前記インバ−ト部材における他の流れに対し、前記接続部の流れを逆向きにして、該接続部からの排水を滝落しさせながらUタ−ンさせるようにして前記他の流れに合流させる請求項2、3、4、5または6に記載の排水ますにあり、また、8)前記接続部に集中一括排水用床下配管設備の下流側を接続した請求項1から7のいずれか1つに記載の屋外の排水ますにあり、また、9)点検筒部材と、これと別体のインバ−ト部材と、からなる排水ますにおいて、前記点検筒部材を、T字における垂直部を該水平部より小径で、かつ、水平部の一方端に偏って設けた1つのチ−ズ状管体で構成し、該垂直部を水平状流入管用接続部とすると共に、該一方端に開閉蓋を設けたことを特徴とする建屋基礎近傍設置可能の塩ビ製排水ますを要旨とするものである。
【0021】
【発明の実施の形態】
本発明を添付図面に示す実施例により詳細にのべる。
【0022】
図1は本発明の第1の実施例の概観図、図2は図1の縦断面図、図3は図1の要部詳細図、図4は図3の要部詳細図、図5は図3の他の要部詳細図、図6は本発明の第2の実施例の縦断面図であって、従来例を示す図7と同一または共通部分は同一符号を付し、その説明を簡略化しているので、そのまま記載があるものとする。
【0023】
「本発明の実施例の概要」
先ず、本発明の実施例の概要を述べる。
【0024】
本実施例の屋外の排水ます10は、特に、建屋2の基礎コンクリ−ト近傍に設置する小口径ますであって、全体が合成樹脂製、特に塩ビ射出成形製であり、その主要寸法は、屋外排水主管106の口径が75mmφから150mmφのものに適用でき、したがって、この排水ます10の点検筒部材11の口径は、150mmφから200mmφに構成される。
【0025】
この排水ます10は、特に図3および図6において、上方の点検筒部材11と下方のインバ−ト部材12とから主としてなり、特に、この点検筒部材11に直接、流入口たる流入管用接続部13が一体成形されて突出しているので、通常の筒状管体でなく、横向きチ−ズ状管体(例えば、T字における垂直部が水平部より小径で、かつ、水平部の一方端に偏って設けられた管体)になっている。
【0026】
そして、この点検筒部材11とインバ−ト部材12とは、このインバ−ト部材12がストレ−トや右、左90度大曲り、45度、合流、球面インバ−ド、段差付き球面インバ−ト等多用化させるため、また、埋設深さ調節等のため、別体で構成し、製造工場または使用時に接合するようにしている。
【0027】
また、この点検筒部材11の上端には直接(リング状蓋枠は設けていても、別の筒体を介在させないことをいう。以下同じ)、開閉蓋14を設けている。そのため、この開閉蓋14と前記接続部13の管頂とは略同一高さにしていて、地表GLと略一致させている。
【0028】
その結果、この排水ます10を用いると、例えば各種の雑排水器具は地表GLより上方にあることから、これらの上方(階上も含む)からの排水を屋外排水主管106に流下する場合、従来のようなエルボ体や垂直管を必要とせず、それだけ設置スペ−スを節減でき、つまり省スペ−ス化となり、極狭小地でも施工極めて簡単に設置できる。
【0029】
そして、屋外排水主管106が深埋設されて土かぶりが増える場合には、点検筒部材11とインバ−ト部材12との間に設けた中間の高さ調節部材15の管長を適宜選定する。したがって、高さ調節がきわめて容易にできる。
【0030】
また、開閉蓋14と接続部13の管頂とを地表GLに略一致させることから、流入管、例えば屋内排水主管5側は土かぶりができず、その保護が心配であるが、この排水ます10は建屋2の近傍に設置するので、この屋内排水主管5側はコンクリ−ト等基礎により外力から保護され、その心配はなく、しかも近接させることから、極狭小地使用に好都合となる。
【0031】
「第1の実施例」
次に、本発明の第1の実施例を述べる。
【0032】
図1から図5において、この第1の実施例の排水ます10は、次のような特定場所の適用例である。
【0033】
例えば、本出願人に係る前掲の特開2002−327474号公報に示す集中一括排水用床下配管設備における屋外の排水ますに用いる適用例である。
【0034】
すなわち、建屋2の床8下の防湿コンクリ−ト3に屋内排水主管5を設け、必然的に地表GLより上方に位置する、この屋内排水主管5を、必然的に所定の埋設深さ(最小約20cm)を有する屋外排水主管106と段差接合(落差接合)するための排水ます10に適用してその特徴を発揮する。
【0035】
これを述べると、図1に示すように屋内排水主管5を排水ます10に接続するため、屋内において、下向きの第1の45度エルボ16、45度傾斜管17、上向きの第2の45度エルボ18、フ−チング基礎19に立設した布基礎24を貫通した第1の横管20および90度曲管21、更には第2の横管(排水枝管)23等からなる緩やかな段差接合構造22を用いる。
【0036】
したがって、この段差接合構造22は、本実施例の排水ます10と組合せたので、更に勾配が緩やかとなり流路に負圧の発生を可及的に防止できる。
【0037】
そして、この段差接合構造22の下流側を排水ます10の流入管用接続部13に単に挿入するだけで接続する、という施工上の特長をもつのである。
【0038】
これを更に施工法の面から詳しく述べると、そもそも木造等戸建住宅の建設では、ごく一般的には次のような施工が行われている。
【0039】
すなわち、木造等戸建住宅の施工では水盛り遺方後、所定の巾と深さの根切りという掘削溝を作り、これに地業を行った後、型枠を立てた前記布基礎24等のコンクリ−ト打ちを行うが、その布基礎24の型枠には排水管用スリ−ブ(ボイド管)の手当てをする。
【0040】
そして、コンクリ−トが固まった後、前記布基礎24に傷をつけないように型枠を外し、土を埋め戻す。その後日、段差接合構造22との接続のため再掘して排水ますを設置する、という施工法が行われている。
【0041】
ところが、本実施例の排水ます10を使用する施工法は、次のように行う。
【0042】
すなわち、前記型枠を除去したとき、前記根切りの掘削溝に屋外排水主管106および排水ます10を直ちに設置する。したがって、布基礎24と、排水ます10等とはフ−チング基礎19の張り出し量を介在させるぐらいで、きわめて接近した状態になる。
【0043】
そのため、この排水ます10の屋外排水主管106における位置を、前記布基礎24の型枠における排水用スリ−ブの軸延長上、すなわち、第1の横管20の管軸延長上より上流側にセットする。
【0044】
もし、第1の横管20の管軸上との交叉点にセットすると、排水ます10と布基礎24とが極めて接近しているだけに、段差接合構造22の下流側との接続が単に挿入するだけとはいえ困難となるばかりか、施工誤差を吸収できない。
【0045】
また、排水ます10の位置を下流側にセットすると、実験の結果や後記理由により、排水ます10内での滝落しに乱れが生じる。
【0046】
さて、これらの屋外排水主管24や排水ます10を仮埋設しておき、段差接合溝22を構築した後、90度曲管(エルボ)21や第2の横管23を介して当該排水ます10と接続する。
【0047】
したがって、以上のような本実施例の排水ます10を使用する施工法によると、排水ます10の設置のために2度掘をなくすことになり、省力化、工程減によるコストダウンが可能となる。
【0048】
したがって、この施工法は前記集合一括排水設備における屋外の排水ます10の使用には、排水ます10が1つないし僅少であるので好都合であるが、これに限らず、一般の排水ますや屋外排水主管の施工法に適用できる。
【0049】
「排水ます10の詳細な説明」
以上のような基礎コンクリ−ト、すなわち、布基礎24の近傍に設置する排水ます10自身を更に詳しく述べる。
【0050】
図2において、この排水ます10の点検筒部材11の上端部には高さ調節自在の開閉蓋14を設け、この開閉蓋14に隣接して1つ(または2つ以上)の流入管用接続部13たるゴム輪受口13Aを設けている。
【0051】
この排水ます10には、このゴム輪受口13Aからの排水を屋外排水主管106へ落差をもって流下させ、その流れを円滑にするため、ゴム輪受口13の軸線延長上にバッフル体(ディフレクタ−体ともいう)と呼ばれる、流れの下向き(ないしUタ−ン)案内部材25を、開閉蓋14を開いたとき取出しができるように、着脱自在に内臓している。すなわち、1種の内副管状のUタ−ン部材を内臓している。
【0052】
この流れの下向き案内部材25を、特にバッフルエルボ25Aで構成すると、排水の周辺への飛散や排水中の固形物の飛散による付着を防止するのは勿論、段差接合構造22やゴム輪受口13Aを水平状に直進する排水の流れを、下向きに円滑に方向転換させてインバ−ト26に案内することができる。
【0053】
このように水平状に直進する排水を強制的に下向きに方向転換させるので、そのとき排水には反動力をもつようになる。
【0054】
したがって、そのままインバ−ト26へ流下させると、インバ−ト部材12がストレ−トや合流等のインバ−ト26の場合、他の第2の流れ、例えばトイレ排水に落下させると、その反動力により第2の流れに衝突し、第2の流れ中の固形物を飛散させるおそれがある。
【0055】
なお、このインバ−ト26は、Uタ−ン部材にとってストレ−ト型の起点用球面インバ−トが最も良好に流出させるが、他の第2の流れがある場合は、ストレ−ト型の段差付き球面インバ−トがUタ−ン部材と良好にマッチして合流させることができる。
【0056】
したがって、この反動力を吸収するため、バッフルエルボ25Aの出口側の向きをインバ−ト26における下流方向に向けると、つまりUタ−ンさせると、意外にも、この滝落しが第2の流れに円滑に合流する。したがって、前記極狭小地設置の効果と相俟って、省スペ−スで、滝落しによる排水の乱れや飛散がなくスム−ズな流れとなる。
【0057】
すなわち、ゴム輪受口13Aの流れの向きを屋外排水主管106における下流方向に向け、したがって、屋内排水主管5の流れ方向を排水ます10内でUタ−ンさせるように屋外排水主管106と接続する。つまり、この排水ます10によって矢印aの排水を滝落しをしながら矢印aのようにUタ−ンさせる。
【0058】
以上の排水ます10を要するに、この排水ます10には、その上部に、排水枝管(23)が下流側から接続される流入口たる枝管接続部(13)があり、その内部に、この下流側から流入した排水を前記枝管接続部(13)から当該排水ます10の下部に設けた流出口に向けUタ−ンさせる部材(25、34)があり、更に、その下部の前記流出口は、屋外排出主管106に接続される構成であるため、省スペ−スで、各種の施工上の誤差を吸収できる配管となり、その上、滝落しによる排水の乱れや飛散がなくスム−ズな流れを発揮させる有益な排水ますを提供できる。
【0059】
「排水ます10の更なる詳細な説明」
次に、かかる排水ます10を更に詳細に述べる。
【0060】
図3において、塩ビ射出成形製点検筒部材11の上端部に、合成樹脂製開閉蓋14を若干の高さが調節できるように、かつ、パッキン27を介して密閉するように設けている。
【0061】
この高さ調節には、開閉蓋14を内嵌しているリング状の合成樹脂製蓋枠28の外面と、点検筒部材11の上端部内面とをネジ部29によって螺着するように構成し、このネジ部29の螺進退により、該開閉蓋14の高さを微調節できるようにしている。
【0062】
したがって、蓋枠28の高さだけ、流入管用接続部13の管頂が低くなるので、この蓋枠28を含めて略同一と称する。
【0063】
そして、このネジ部29に土砂や浸入水の入るのを防ぐため、この蓋枠28の上端に折り返し部30を設けて、点検筒部材11の上端外面にわたりカバ−する。
【0064】
したがって、点検筒部材11と蓋枠28との2つの最少部品でありながら、部品点数を増さず、これらの浸入防止をすることができる。
【0065】
また、この高さ調節は、点検筒部材11や高さ調節部材15の管長を特に配慮しない場合、または既に組付けられている場合、地表GLに対する施工時の調節や新規に布設したアスファルトに対する調節等に用いる。
【0066】
次に、点検筒部材11であるが、これは、前記のようにチ−ズ状管体で形成されており、この点検筒部材11の下部には差口部31を形成し、高さ調節部材15の上端側に挿入するようにしている。
【0067】
この高さ調節部材15の下端側は、インバ−ト部材12の上方開口側に形成した受口部40に挿入する。
【0068】
次に、バッフルエルボ25Aであるが、これは塩ビ(合成樹脂)射出成形製であって、排水の流れを矢印aのように滝落しして更にUタ−ンさせるため、バッフルエルボ本体33と半椀状のUタ−ン助勢案内部材34と、これらを連結し、高さ調節可能の連結部材35と、から、互に接着接合して一体モノに構成している。したがって、これらの具体的部材を含めてUタ−ン部材と総称する。
【0069】
このUタ−ン助勢案内部材34の下端、つまりUタ−ン部材の下端は、屋外排水主管106の管頂と略一致させて第2の流れの満管流に支障を与えず、固形物の係止を防止している。
【0070】
また、バッフルエルボ25Aの寸法および形状は、ゴム輪受口13Aの口径が例えば75mmφの場合、バッフルエルボ本体33の入口側は、約97mm、83mmの楕円形(図5(A)参照)とし、その出口側は約77mmφの円形とする異形エルボで構成している。勿論、このバッフルエルボ本体33の入口側は、ゴム輪受口13と略同径の円形であってもよい。
【0071】
次に、バッフルエルボ25Aの点検筒部材11への着脱の1例を述べる。
【0072】
図4および図5において、図4(A)は点検筒部材11の平面図、(B)は(A)の縦断面図、(C)は(B)のB矢視断面図、(D)は(A)のA矢視側面図である。
【0073】
これらの図において、バッフルエルボ本体33の略中央部の外面には、左右1対の水平部をもつアングル形状の係止片36、36を一体的に突設している。
【0074】
この係止片36の先端は、後記の棚部37における水平円弧に合致するように円弧に形成している。
【0075】
また、点検筒部材11のゴム輪受口13Aの軸延長側の内面には、左右1対の、水平円弧状になった水平部をもつアングル形状の棚部37、37を突設している。
【0076】
この棚部37の後端(反ゴム輪受口側、以下同じ)には、上方に後方傾斜した挿入案内片38を連設している。
【0077】
そこで、Uタ−ン助勢案内部材34等を取付けたバッフルエルボ本体33の入口側をゴム輪受口13の出口側に向けて、その上方に突設した把持部39を把持して、その係止片36を挿入案内片38に沿って上方から若干強制的に挿入すると、その挿入案内片38により係止片36は前方へ案内され、棚部37上に載置すると共に、係止片36の先端部に形成した円弧が棚部37の円弧状アングル垂直部に接合する。
【0078】
そのとき、バッフルエルボ25Aの入口はゴム輪受口13Aの出口と密接して接合する。勿論、バッフルエルボ25Aを、点検・掃除のため取出すには、開閉蓋14を開き、把持部39を把持して引出せばよい。
【0079】
なお、点検筒部材11の上端内周に設けて前記ネジ部(メネジ)29は途切れ状ネジ体(勿論、全周ネジ体でも可)で構成している。
【0080】
「第2の実施例」
次に、本発明の第2の実施例について述べる。
【0081】
図6において、塩ビ射出成形製点検筒部材11の上端部には直接、合成樹脂製開閉蓋14をパッキン27を介して密閉状に設けている。この開閉口に水平方向に隣接して流入口たる流入管用接続部13、すなわち、受口13Bを一体形成している。
【0082】
この受口13Bの口径は若干大径にして、これにインクリ−ザと呼ばれる、偏った縮径ソケット39を嵌着し、前記段差接合構造22の第2の横管23を接着接合できるようにしている。
【0083】
この縮径ソケット39はその受口部が偏心しているので、排水ます10を設置した後、この受口部を回動させると開閉蓋14の高さ微調整ができる。勿論、この縮径ソケット39の代りにS型ソケットを外嵌してもよい。
【0084】
この点検筒部材11には、高さ調節部材15を介してインバ−ト部材12を設けているが、この高さ調節部材15を長寸にした場合、排水の流下が滝落し状になるので、この点検筒部材11内にも、前記接続部13の軸線延長上にディフレクタ−と呼ばれる、流れの下向き案内部材25を、点検・掃除に支障のないように着脱自在に設け、接続部13から水平状に直進する排水を、下方のインバ−ト26に案内するように結んでいる。つまり、流入口から流出口へ流れをUタ−ン状に結ぶ案内部材を内臓している。

TECHNICAL FIELD OF THE INVENTION
The present invention particularly relates to a synthetic resin drainage that can be installed near the foundation of a building in a house, and more particularly to a drainage sink installed in a house for saving space.
[0002]
[Prior art]
Currently, drainage underfloor plumbing equipment using one collective or one header-type joint has been actively proposed (for example, Japanese Patent Application Laid-Open No. 2001-220796 and Japanese Patent Application Publication No. 327474, etc.).
[0003]
According to such drainage underfloor plumbing equipment, 1) the drainage pipe can be made into a unit, which has the effect of reducing the amount of labor on site, and 2) when using a collective, this acts as a kind of air accumulator. 3) If the underfloor piping is not buried, the earthwork cost will be reduced. 4) The number of outdoor drains and drain pipes will be reduced. It is possible.
[0004]
Underfloor piping equipment using such one header-type joint will be further described based on the above-mentioned Japanese Patent Application Laid-Open No. 2001-220796.
[0005]
In FIG. 7, this is provided on a moisture-proof concrete 3 under a floor 8 of a building 2 such as a detached house.
[0006]
The downstream side of the underfloor piping equipment 1B penetrates the fabric foundation 24 of the building 2 and is buried outdoors through a 90-degree large bend Y-joint 101, a vertical short pipe 102, a 90-degree elbow 103, and a horizontal short pipe 104. The drain is connected to a drain 105.
[0007]
The drainage basin 105 is connected to an outdoor drainage main pipe 106 buried in the site, and the outdoor drainage main pipe 106 is connected to a public square (not shown).
[0008]
By the way, the underfloor plumbing equipment 1B includes a header-type joint 107 and an indoor drainage main pipe 5 under the floor, and one header-type joint 107 includes a flush toilet, a washroom, a washing machine, and a bathroom (not shown). Each drainage branch pipe end connected to various miscellaneous drainage appliances such as a kitchen is connected. Of course, these instruments are provided with an instrument trap.
[0009]
Therefore, in order to prevent all of these instrument traps from being breached, a vent pipe 109 opened outdoors is attached to the header-type joint 107, and this vent pipe 109 allows the header-type joint 107 and the indoor drain main pipe 5 to be opened. And prevents the instrument trap from being completely opened.
[0010]
That is, since the header-type joint 107 is provided with one ventilation pipe 109, the water trapping of these equipment traps can be effectively maintained without providing a number of ventilation pipes corresponding to various miscellaneous drainage equipment. It is said that material costs and construction costs can be reduced.
[0011]
On the other hand, the burial depth of the outdoor drainage basin (two even for toilets) 105 used for such collective concentration is determined by the ordinance, etc., and the depth of the public drainage sill (not shown) is determined. Since the slope of the pipe 106 is determined, and the minimum earth covering of the outdoor drainage main pipe 106 is also set to 20 cm according to the regulations or the like, the 90-degree large bend Y joint 101 and the vertical short pipe 102 are used as described above. , A 90-degree elbow 103 and a short horizontal tube 104 are used to form a step-joined structure (also referred to as a head structure; the same applies hereinafter) 110 so that the depth can be obtained.
[0012]
[Problems to be solved by the invention]
However, in the outdoor drainage trough 105 used for such collective concentration, the step junction structure 110 as described above is formed, so that the number of parts is increased and the number of parts, which is one of the features of collective concentration drainage, is reduced. Of course, it is not preferable, because the installation space is so large that it is not preferable in narrow land.
[0013]
Various proposals are known in Japanese Utility Model Registration No. 2554325 and Japanese Utility Model Laid-Open Publication No. 3-93890 regarding a small caliber that can be used in a narrow land.
[0014]
The proposal disclosed in Japanese Utility Model Laid-Open Publication No. 3-93890 will be described.
[0015]
This means that a main body is provided with a pair of upstream and downstream connections on a main shaft, and a connection portion for a check tube is provided on a surface side orthogonal to the main shaft. )) In the outdoor drainage where the drainage is combined, the elbow body for connecting the vertical pipe is horizontally and integrally attached to the main body, thereby shortening the distance between the main body and the vertical pipe. This is a proposal for drainage masu that can be used even in narrow land.
[0016]
However, this proposal cannot be adopted because of the following problems.
[0017]
(1) When the proposed outdoor drainage masu is used in a very narrow area, an elbow body protrudes horizontally from the main body, and a vertical pipe (corresponding to reference numeral 102 in FIG. 7) rises up. Therefore, it occupies the installation space accordingly, and it is still difficult to use.
[0018]
{Circle around (2)} A second elbow (corresponding to the reference numeral 103 in FIG. 7) is required to allow the upper drainage to flow into the vertical pipe.
[0019]
Therefore, the present invention was created in an attempt to solve such problems, and in particular, to change the way of thinking and to focus on changing the construction method, It was created with a focus on outdoor drainage masu, which is not covered with soil or is thinly applied.
[0020]

[0021]

[0022]

FIG. 6 is a longitudinal sectional view of another embodiment of the present invention. FIG. 6 is a longitudinal sectional view of the second embodiment of the present invention. In FIG. Since it is simplified, it is assumed that the description is provided as it is.
[0023]
"Overview of Examples of the Present Invention"
First, an outline of an embodiment of the present invention will be described.
[0024]
The outdoor drainage trough 10 of this embodiment is a small-diameter trough which is installed in the vicinity of the foundation concrete of the building 2 and is entirely made of synthetic resin, especially PVC injection molding. The drainage main pipe 106 can be applied to a pipe having a diameter of 75 mmφ to 150 mmφ. Therefore, the diameter of the inspection cylinder member 11 of the drainage trough 10 is configured to be 150 mmφ to 200 mmφ.
[0025]
3 and 6, the drainage trough 10 mainly comprises an upper inspection tube member 11 and a lower inverting member 12. In particular, the drainage trough 10 is directly connected to the inspection tube member 11 for an inflow pipe serving as an inlet. 13 is integrally formed and protruded, so that it is not a normal tubular tube, but a transverse cheese-like tube (for example, a vertical portion in a T-shape is smaller in diameter than a horizontal portion, and is provided at one end of the horizontal portion. It is a tube body that is provided unevenly.
[0026]
The inspection tube member 11 and the inverting member 12 are such that the inverting member 12 is bent at a straight angle or a large 90 ° right or left, 45 °, merges, a spherical invert, or a spherical invert with a step. In order to make it more versatile, to adjust the burial depth, etc., it is constructed separately and joined at the manufacturing factory or at the time of use.
[0027]
Further, an opening / closing lid 14 is provided directly on the upper end of the inspection cylinder member 11 (meaning that another cylindrical body is not interposed, even if a ring-shaped lid frame is provided. The same applies hereinafter). For this reason, the opening / closing lid 14 and the pipe top of the connecting portion 13 are set to have substantially the same height, and are made substantially coincident with the ground surface GL.
[0028]
As a result, when the drainage trough 10 is used, for example, since various miscellaneous drainage devices are above the ground surface GL, when drainage from above (including on the floor) flows down to the outdoor drainage main pipe 106, there is a problem. Such an elbow body and a vertical pipe are not required, and the installation space can be saved accordingly, that is, space can be saved, and installation can be performed extremely easily even in a very small land.
[0029]
When the outdoor drainage main pipe 106 is deeply buried and soil cover increases, the pipe length of the intermediate height adjusting member 15 provided between the inspection tube member 11 and the inverter member 12 is appropriately selected. Therefore, the height can be adjusted very easily.
[0030]
In addition, since the opening / closing lid 14 and the pipe top of the connecting portion 13 substantially match the ground surface GL, the inflow pipe, for example, the indoor drain main pipe 5 side cannot be covered with soil, and there is a concern about protection thereof. Since 10 is installed near the building 2, the indoor drain main pipe 5 side is protected from external force by a foundation such as concrete, and there is no concern about it.
[0031]
"First Embodiment"
Next, a first embodiment of the present invention will be described.
[0032]
1 to 5, the drainage trough 10 of the first embodiment is an application example of a specific place as follows.
[0033]
For example, this is an application example used for an outdoor drainage pit in a centralized collective drainage underfloor plumbing facility disclosed in Japanese Patent Application Laid-Open No. 2002-327474 of the present applicant.
[0034]
That is, the indoor drainage main pipe 5 is provided in the moisture-proof concrete 3 below the floor 8 of the building 2, and the indoor drainage main pipe 5, which is inevitably located above the ground surface GL, is inevitably provided at a predetermined burial depth (minimum). The present invention is applied to the drain mast 10 for step-joining (drop joining) with the outdoor drain main pipe 106 having about 20 cm) to exhibit its characteristics.
[0035]
In order to connect the indoor drain main pipe 5 to the drain basin 10 as shown in FIG. 1, a downward first 45-degree elbow 16, a 45-degree inclined pipe 17, and an upward second 45-degree pipe are used indoors. A gentle step formed by a first horizontal pipe 20 and a 90-degree bent pipe 21 penetrating a cloth foundation 24 erected on an elbow 18, a footing foundation 19, and a second horizontal pipe (drain branch pipe) 23. A joint structure 22 is used.
[0036]
Therefore, since the step joining structure 22 is combined with the drainage trough 10 of the present embodiment, the gradient becomes further gentle, and generation of negative pressure in the flow path can be prevented as much as possible.
[0037]
Then, there is a constructional feature that the downstream side of the stepped joint structure 22 is connected by simply inserting it into the inflow pipe connecting portion 13 of the drainage drain 10.
[0038]
This will be described in more detail in terms of the construction method. In the construction of a detached house such as a wooden house, the following construction is generally performed in the first place.
[0039]
That is, in the construction of a detached house such as a wooden house, after excavation, a digging groove having a predetermined width and depth is formed. The fabric of the cloth base 24 is treated with a drain pipe sleeve (void pipe).
[0040]
Then, after the concrete is hardened, the form is removed so as not to damage the cloth foundation 24, and the soil is backfilled. On the following day, a construction method of re-digging and installing a drainage basin for connection with the step joint structure 22 is being performed.
[0041]
However, the construction method using the drainage masu 10 of this embodiment is performed as follows.
[0042]
That is, when the form is removed, the outdoor drainage main pipe 106 and the drainage trough 10 are immediately installed in the excavation trench of the root cutting. Therefore, the cloth foundation 24 and the drainage mast 10 and the like are in a state of being very close to each other with the amount of protrusion of the footing foundation 19 interposed therebetween.
[0043]
Therefore, the position of the drainage trough 10 in the outdoor drainage main pipe 106 is set on the axial extension of the drainage sleeve in the formwork of the cloth foundation 24, that is, on the upstream side of the pipe axial extension of the first horizontal pipe 20. set.
[0044]
If it is set at the intersection of the first horizontal pipe 20 with the pipe axis, the connection with the downstream side of the step joint structure 22 is simply inserted because the drainage trough 10 and the cloth foundation 24 are very close. Not only does it make it difficult, but it cannot absorb construction errors.
[0045]
Also, if the position of the drainage trough 10 is set on the downstream side, the waterfall in the drainage trough 10 will be disturbed due to the results of experiments and the reasons described below.
[0046]
Now, these outdoor drainage main pipes 24 and drainage troughs 10 are temporarily buried, and a step junction groove 22 is constructed. Then, the drainage drainage troughs 10 through a 90-degree bent pipe (elbow) 21 and a second horizontal pipe 23 are drained. Connect with
[0047]
Therefore, according to the construction method using the drainage trough 10 of the present embodiment as described above, digging is eliminated twice for the installation of the drainage trough 10, and cost reduction can be achieved by labor saving and process reduction. .
[0048]
Therefore, this construction method is convenient for use of the outdoor drainage trough 10 in the collective drainage system because the drainage trough 10 is only one or a little, but is not limited to this. Applicable to main pipe construction method.
[0049]
"Detailed explanation of drainage 10"
The above-mentioned foundation concrete, that is, the drainage basin 10 installed near the cloth foundation 24 will be described in further detail.
[0050]
In FIG. 2, an opening / closing lid 14 is provided at the upper end of the inspection tube member 11 of the drainage trough 10, the height of which can be adjusted. One (or two or more) connecting portions for inflow pipes are provided adjacent to the opening / closing lid 14. A 13 ring rubber socket 13A is provided.
[0051]
The drainage trough 10 has a baffle (a deflector) on the axial extension of the rubber ring receiving port 13 in order to make the drainage from the rubber ring receiving port 13A flow down to the outdoor drain main pipe 106 with a drop and to make the flow smooth. A downward (or U-turn) guide member 25, which is called a body, is detachably provided so that the guide member 25 can be taken out when the opening / closing lid 14 is opened. That is, one type of internal sub-tubular U-turn member is incorporated.
[0052]
When the downward guide member 25 of this flow is particularly constituted by a baffle elbow 25A, it is possible not only to prevent the wastewater from scattering around and to adhere to the solid matter in the wastewater due to the scattering, but also to form the step-joining structure 22 and the rubber ring receiving port 13A. Can be guided to the invert 26 by turning the flow of the drainage, which travels straight horizontally, downward smoothly.
[0053]
As described above, since the drainage that travels straight horizontally is forcibly turned downward, the drainage has a reaction force at that time.
[0054]
Therefore, if the inverting member 12 is the invert 26 such as a straight or a merging, it is dropped to another second flow, for example, the toilet drainage. As a result, it may collide with the second flow and scatter solids in the second flow.
[0055]
The invert 26 allows a straight type starting spherical invert to flow out best for the U-turn member. However, when there is another second flow, the straight type is used. The stepped spherical invert is well matched to the U-turn member and can be joined.
[0056]
Therefore, when the direction of the outlet side of the baffle elbow 25A is directed to the downstream direction in the invert 26 to absorb this reaction force, that is, when the U-turn is performed, unexpectedly, this waterfall falls into the second flow. To join smoothly. Therefore, in combination with the effect of the installation in the extremely narrow land, the space can be saved, and the drainage is not disturbed or scattered due to a waterfall, and a smooth flow can be obtained.
[0057]
That is, the direction of the flow of the rubber ring receiving port 13A is directed to the downstream direction in the outdoor drainage main pipe 106, and therefore, the flow direction of the indoor drainage main pipe 5 is connected to the outdoor drainage main pipe 106 so as to make a U-turn inside the drainage pipe 10. I do. In other words, the drainage of the arrow a is made U-turn as shown by the arrow a while the drainage of the arrow a is dropped by the drainage trough 10.
[0058]
In sum, the drainage trough 10 has a branch pipe connection portion (13) as an inflow port to which a drainage branch pipe (23) is connected from the downstream side. There are members (25, 34) for making U-turn from the branch pipe connection portion (13) toward the outlet provided at the lower part of the drainage trough 10 from the downstream side, and further, there is a member (25, 34) at the lower part thereof. Since the outlet is configured to be connected to the outdoor discharge main pipe 106, the pipe is a space-saving pipe capable of absorbing various construction errors, and furthermore, there is no turbulence or scattering of the drainage caused by a waterfall, and the outlet is smooth. It can provide a useful drainage that exerts a natural flow.
[0059]
"Further detailed explanation of drainage masturbation 10"
The drainage trough 10 will now be described in more detail.
[0060]
In FIG. 3, a synthetic resin opening / closing lid 14 is provided at the upper end portion of the inspection tube member 11 made of polyvinyl chloride injection molding so that the height can be adjusted slightly, and the lid 14 is sealed via a packing 27.
[0061]
For this height adjustment, the outer surface of the ring-shaped synthetic resin lid frame 28 in which the opening / closing lid 14 is fitted, and the inner surface of the upper end portion of the inspection tube member 11 are screwed with the screw portion 29. The height of the opening / closing lid 14 can be finely adjusted by screwing and retracting the screw portion 29.
[0062]
Therefore, the pipe top of the inflow pipe connecting portion 13 becomes lower by the height of the lid frame 28, and therefore, the same including the lid frame 28 is called.
[0063]
Then, in order to prevent earth and sand or infiltration water from entering the screw portion 29, a folded portion 30 is provided at the upper end of the lid frame 28 so as to cover the upper end outer surface of the inspection tube member 11.
[0064]
Therefore, it is possible to prevent the inspection tube member 11 and the lid frame 28 from penetrating without increasing the number of parts even though they are the two minimum parts.
[0065]
In addition, this height adjustment is performed when the pipe length of the inspection tube member 11 or the height adjustment member 15 is not particularly taken into consideration, or when it is already assembled, adjustment at the time of construction on the ground surface GL or adjustment for newly laid asphalt. Used for etc.
[0066]
Next, the inspection tube member 11 is formed of a cheese-like tube as described above, and a spout 31 is formed at the lower portion of the inspection tube member 11 to adjust the height. It is inserted into the upper end side of the member 15.
[0067]
The lower end of the height adjusting member 15 is inserted into a socket 40 formed on the upper opening side of the inverter member 12.
[0068]
Next, a baffle elbow 25A is made of a PVC (synthetic resin) injection molding. The baffle elbow main body 33 and the baffle elbow main body 33 are used to make the flow of drainage water fall as shown by an arrow a and further make a U-turn. A semi-bowl-shaped U-turn assisting guide member 34 and a connecting member 35 that connects these members and that can be adjusted in height are adhered and joined to each other to form an integral monolith. Therefore, these specific members are collectively referred to as U-turn members.
[0069]
The lower end of the U-turn assist guide member 34, that is, the lower end of the U-turn member substantially coincides with the top of the outdoor drain main pipe 106 so as not to impede the full flow of the second flow, and to prevent solid matter. Is prevented from locking.
[0070]
When the diameter of the rubber ring socket 13A is, for example, 75 mmφ, the inlet side of the baffle elbow main body 33 has an oval shape of about 97 mm and 83 mm (see FIG. 5A). The outlet side is constituted by a modified elbow having a circular shape of about 77 mmφ. Of course, the inlet side of the baffle elbow main body 33 may have a circular shape having substantially the same diameter as the rubber ring receiving port 13.
[0071]
Next, an example of attachment and detachment of the baffle elbow 25A to and from the inspection tube member 11 will be described.
[0072]
4 and 5, FIG. 4A is a plan view of the inspection tube member 11, FIG. 4B is a longitudinal sectional view of FIG. 4A, FIG. 4C is a sectional view of FIG. FIG. 3A is a side view of FIG.
[0073]
In these figures, angle-shaped locking pieces 36, 36 having a pair of left and right horizontal portions are integrally protruded from an outer surface of a substantially central portion of the baffle elbow main body 33.
[0074]
The tip of the locking piece 36 is formed in an arc so as to match a horizontal arc in the shelf 37 described later.
[0075]
Angled ledges 37, 37 having a pair of left and right horizontal circular arc-shaped horizontal portions project from the inner surface of the inspection cylinder member 11 on the shaft extension side of the rubber ring receiving port 13A. .
[0076]
At the rear end of this shelf 37 (on the opposite side of the rubber ring receiving port, the same applies hereinafter), an insertion guide piece 38 inclined rearward upward is continuously provided.
[0077]
Therefore, the inlet side of the baffle elbow main body 33 to which the U-turn assisting guide member 34 and the like are attached is directed toward the outlet side of the rubber ring receiving port 13 and the holding portion 39 projecting upward is gripped. When the stop piece 36 is slightly forcibly inserted from above along the insertion guide piece 38, the locking piece 36 is guided forward by the insertion guide piece 38, and is placed on the shelf 37, and the locking piece 36 Is joined to the arc-shaped vertical portion of the shelf 37.
[0078]
At this time, the inlet of the baffle elbow 25A is closely joined to the outlet of the rubber ring receiving port 13A. Of course, in order to take out the baffle elbow 25A for inspection and cleaning, it is sufficient to open the opening / closing lid 14, hold the grip portion 39, and pull it out.
[0079]
The screw portion (female screw) 29 is provided on the inner periphery of the upper end of the inspection tube member 11, and is formed of a discontinuous screw body (of course, a whole circumference screw body is also possible).
[0080]
"Second embodiment"
Next, a second embodiment of the present invention will be described.
[0081]
In FIG. 6, a synthetic resin opening / closing cover 14 is directly provided in a sealed manner at the upper end of the inspection tube member 11 made of PVC injection molding via a packing 27. The connecting portion 13 for the inflow pipe, which is the inflow port, that is, the receiving port 13B is formed integrally with the opening / closing port in the horizontal direction.
[0082]
The diameter of the receiving port 13B is made slightly larger, and a reduced diameter socket 39 called an increser is fitted into the receiving port 13B so that the second horizontal pipe 23 of the stepped connection structure 22 can be bonded and bonded. ing.
[0083]
Since the receiving portion of this reduced-diameter socket 39 is eccentric, the height of the opening / closing lid 14 can be finely adjusted by rotating the receiving portion after the drain 10 is installed. Of course, an S-type socket may be externally fitted instead of the reduced diameter socket 39.
[0084]
The inspection cylinder member 11 is provided with an inverting member 12 via a height adjusting member 15. However, if the height adjusting member 15 is made long, the drainage water flows down like a waterfall. A downward guide member 25 called a deflector is also provided in the inspection tube member 11 on the extension of the axis of the connection portion 13 so as to be detachable so as not to hinder inspection and cleaning. Drainage that goes straight horizontally is guided to the lower invert 26. That is, a guide member for connecting the flow from the inflow port to the outflow port in a U-turn shape is provided.
[0085]
In the case where the number of the connection portions 13 is one as shown in the figure, the deflector is formed of a bowl with one mountain. In the case of the two (plural) connection portions 13, the number of the mountain (a plurality of mountains) is two. It is made of a bowl and made into one body, making it easy to attach and detach.
[0086]
Therefore, this drainage trough 10 is used not only for the outdoor drainage trough 10 in the collective collective drainage system but also for general outdoor drainage troughs, that is, at the starting point, right-angle corner, middle point, etc. of the main drainage pipe 106. It can be used by changing the bowl shape of the deflector. Of course, this deflector is not essential for the drain 10 and may not be used in the case of the starting drain. In addition, when it is slightly away from the foundation of the building 2, the horizontal inflow pipe may be protected by asphalt or the like.
[0087]
In addition, a finned tube is formed on a part of the outer peripheral surface of the inspection tube member 11, and the strength is enhanced by the uneven shape 41.
[0088]
Inverting member 12 is formed with an invert 26 at the bottom thereof. In the case of the straight type, inlet port 42 on the inlet side and outlet port 42 on the outlet side are formed on the same axis so that it can be used outdoors. It is adhesively bonded to the drain main pipe 106. Of course, these receiving ports 42, 42 may be connection parts such as rubber ring receiving ports.
[0089]
The protection of the horizontal connection portion 13 for the inflow pipe is not limited to the foundation of the building, but may be thin asphalt or other structures such as a fence or a permanent tank.
[0090]
【The invention's effect】
According to the present invention, the drainage trough (10) has a built-in guide member for regulating the flow in a U-turn shape. Therefore, the outdoor drainage main pipe (106) having the drainage trough (10) on the pipe axis is installed in the building. The drain can be made to be extremely close to the space-saving type (10), and the flow of the head can be made smooth.
[0091]
In addition, since the inspection tube member is integrally provided with an opening / closing lid and a connection portion for a horizontal inflow pipe substantially coinciding with the surface of the ground, the drainage from the upper part can be directly performed, while the structure is simple and possible. Even in a small land, the connection can be made very easily by simply connecting.
[0092]
In particular, instead of not covering the horizontal inflow pipe with soil, it is protected by other facilities, so it is not subjected to external force and the drainage head can be increased accordingly, or the lower inverting member is placed on the ground surface. The access to the main drainage pipe can be buried shallowly.
