Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は防火貯水槽のマンホールに用いられるマンホー
ル蓋受枠に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a manhole cover receiving frame used for a manhole of a fire protection water tank.
防火貯水槽のマンホールにホースを挿入して高圧で注水
して補給する作業を行う場合、水圧によりホースが屈曲
して跳ね、マンホールからホースが抜け出したりするこ
とがある。When a hose is inserted into the manhole of a fire protection water tank and water is supplied at high pressure to replenish it, the hose may bend and bounce due to water pressure, and the hose may slip out of the manhole.
そこで従来はマンホール鉄蓋をホースに乗せたり、ホー
スを手で押えたりしてそれを防いでいるが、前者の方法
はマンホール鉄蓋を跳ね飛ばすことがあって危険であ
り、また後者の方法は１人の作業要員が他の重要な仕事
ができなくなるので不具合であった。Therefore, conventionally, the manhole iron cover is put on the hose or the hose is pressed by hand to prevent it, but the former method is dangerous because it may bounce off the manhole iron cover, and the latter method is It was a malfunction because one worker could not do other important work.
この問題を解決するため、本考案者は先にマンホール蓋
受枠本体の内側縁に環状のホース保持具を屈曲自在に設
け、このホース保持具でホースのマンホールからの抜け
出しを防止する方法を提案した（実公昭62-39137号公報
参照） ところが、この方法はホース保持具が可動であるため、
騒音を発するという問題と、ホースを抜く時にホース保
持具を手でホースと直交する位置に保持していなければ
ならないという問題があった。In order to solve this problem, the present inventor previously proposed a method of flexibly providing an annular hose holder on the inner edge of the manhole cover receiving frame body and preventing the hose from coming out of the manhole with this hose holder. (Refer to Japanese Utility Model Publication No. 62-39137) However, since the hose holder is movable in this method,
There was a problem that noise was generated and a problem that the hose holder had to be held by hand at a position orthogonal to the hose when the hose was pulled out.
そこでこの考案は先に提案した方法よりもホースの操作
が楽で、しかも騒音を発することのないものを提案しよ
うとするものである。Therefore, this invention intends to propose a hose that is easier to operate and does not emit noise than the previously proposed method.

である。The present invention has been made to solve this problem, and a hose fixing coupling is provided on the inner edge of the manhole cover receiving frame, and the hose coupling is connected and fixed to it during pouring and draining, so that a safe refilling work can be performed. It was made to take place.

ある。The drawing shows an embodiment of the present invention, in which an opening / closing bracket 3 is provided on the inside of a manhole cover receiving frame body 1, a hose fixing coupling 2 is provided on the manhole lid receiving frame body 1, and a coupling 5 of a hose 4 is connected to the hose 4 when using the hose. The hose 4 is connected to the fixing coupling 2 so as not to come out.

音を発しない。またホース３を外す場合も簡単に操作す
ることができる。According to the structure of the present invention, since the end portion of the water supply hose 4 is fixed, the hose end portion does not dance as in the conventional case, so that no noise is generated. Also, when the hose 3 is removed, it can be easily operated.
