Description

【0001】
【産業上の利用分野】
本発明は、地表面の傾斜勾配、高さに合わせて掃除口管の上端部に蓋体をセットできる汚水桝の掃除口に関する。
【0002】
【従来の技術】
汚水桝から上方に立ち上げた掃除口管の上端部に蓋体をセットするとき、該蓋体が地表面の傾斜勾配や、高さと一致しないと見栄えが悪いだけでなく、蓋体につまずいて転倒したり、足をとられて怪我をするという危険性がある。そこで、従来から地表面の傾斜勾配や、高さに合わせて蓋体をセットする方法が種々提案されている。例えば、実開平5ー87087号公報には、アジャスタボルトの締め加減によって蓋保持筒体の傾斜勾配と高さを調整し、蓋体を地表面と面一にする掃除口が提案されている。
【0003】
【発明が解決しようとする課題】
しかしながら、この従来の掃除口は、アジャスタボルトが蓋保持筒体の管壁内に軸芯方向に貫通して埋め込まれているため、必然的に蓋保持筒体の管壁が肉厚となって重量が嵩み、取り扱いに不便であるだけでなく、コストアップが避けられなかった。
【0004】
本発明はかかる課題を解決したものであって、安価に提供できると共に施工性に優れ、地表面の傾斜勾配、高さに合わせて蓋体を簡単にセットできる汚水桝の掃除口を提供するものである。
【0005】
【課題を解決するための手段】
本発明の掃除口は、汚水桝から上方に立ち上げた掃除口管の上端部にゴムリングを介して蓋保持筒体を上下動可能に遊嵌し、該蓋保持筒体の上端部を拡径して形成した蓋受部に蓋体を着脱自在に装着した掃除口であって、前記蓋保持筒体の蓋受部内側の外周部適所から短管の外側にアジャスタボルトを垂下させると共に、該アジャスタボルトを掃除口管の上端部に係止した支持部材と螺合したことを特徴とする。
【0006】
【作用】
現場での配管施工の際に、掃除口管に遊嵌した蓋保持筒体を手で持ち上げ、蓋受部の外周部適所から垂下させたアジャスタボルトの締め加減を調整すると、蓋受部に装着した蓋体が地表面と面一となる。
【0007】
【実施例】
以下、本発明の実施例を図面にて詳細に説明する。
図1は本発明の一実施例を示す断面図、図2は蓋保持筒体を所定位置に支持した状態の要部断面図であって、図中の符号1は汚水桝、2は掃除口管、3は蓋保持筒体、4はゴムリング、5は蓋体、6はアジャスタボルト、7は支持部材である。
【0008】
汚水桝1は塩化ビニル樹脂等の合成樹脂を射出成形して一体的に形成したものであって、上方が開口した有底筒状をなす桝本体10の底部に排水溝13が設けられている。そして、前記排水溝13と連通して桝本体10の側壁に流入管の接続口11と流出管の接続口12とが設けられている。
【0009】
この汚水桝1は地中に埋設されるものであって、地面を掘り起こして形成した掘削溝の底部に汚水桝1を設置してからそれぞれの接続口11,12に下水管Pの上流側と下流側の端部を接続する。一方、桝本体10の上方接続口に掃除口管2を嵌挿し、該掃除口管2の上端部にゴムリング4を介して蓋保持筒体3を上下動かっ傾斜可能に遊嵌する。
【0010】
前記蓋保持筒体3は掃除口管2の内径よりもやや小径の短管の一端部を拡径して蓋受部31を形成したものであって、該蓋受部31に蓋体5が着脱自在に装着される。また、蓋保持筒体3の他端部外周面には2本の突条32が設けられており、それぞれの突条32,32の間に掃除口管2の内周面と密接するゴムリング4が装着されている。
【0011】
前記蓋受部31の外周部を貫通してアジャスタボルト6が垂下しており、該アジャスタボルト6の下部が掃除口管2の上端部に係止された支持部材7と螺合している。アジャスタボルト6は円周を2等分あるいは3等分する複数箇所から垂下させるのが好ましく、該アジャスタボルト6の締め加減を調整することによって、蓋保持筒体3の傾斜勾配、及び高さを調整できるようになっている。尚、61は蓋受部31の下方からアジャスタボルト6を支持するリング部材である。
【0012】
前記支持部材7は適宜形状とすることができるが、図2に示した如く掃除口管2の上端部に係止される支持部71とアジャスタボルト6が螺合するねじ部72とが段差部73を介して接続した構造とすると、図中に破線で示したように支持部材7の上下を逆にするだけで、蓋保持筒体3の支持高さを広範囲に調整できるという利点がある。
【0013】
次に、蓋保持筒体3の傾斜角度と高さを調整する手順と、その施工作業を説明する。先ず、掃除口管2の上端部に遊嵌した蓋保持筒体3を手で持ち上げ、蓋受部31が地表面と面一となる状態に保持しながらアジャスタボルト6の締め加減を調整して支持部材7を掃除口管2の上端面に当接させる。このとき、ドライバー等でアジャスタボルト6の頭部を回して調整するとよい。
【0014】
このようにして蓋保持筒体3の蓋受部31の2〜3カ所から垂下させたアジャスタボルト6と、支持部材7で蓋保持筒体3の傾斜角度と高さの調整をしてから蓋受部31に蓋体5を装着する。そこで、図1に示した如く土砂等の埋め戻しを行ない、地表面をコンクリート、アスファルト等で舗装する。すると、蓋保持筒体3がコンクリート、アスファルト等で固定されて施工作業が完了する。
【0015】
【発明の効果】
以上詳述した如く、本発明は蓋保持筒体を軽量とすることができるので、安価に提供できると共に、施工作業の際の取り扱いが容易である。また、掃除口管に遊嵌した蓋保持筒体を手で持ち上げ、該蓋保持筒体の蓋受部の外周部から垂下させたアジャスタボルトの締め加減を調整するだけで、蓋保持筒体の傾斜角度と高さの調整が行なえるので、現場での施工作業が極めて簡単に行なえる。
