Description

【考案の詳細な説明】 〔産業上の利用分野〕 本考案は防火下水道のマンホールや防火貯水槽
のマンホールなど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 frame used for manholes in fire protection sewers, manholes in fire protection water tanks, and the like.

〔従来技術とその問題点〕[Prior art and its problems]

防火下水道や防火貯水槽のマンホールにホース
を挿入して消火活動を行なう時や、防火水を高圧
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 extinguishing a fire by inserting a hose into the manhole of a fire prevention sewer or fire prevention water tank, or when replenishing fire prevention water by injecting it at high pressure, the hose may bend and bounce due to the water pressure, causing the hose to slip out of the manhole. Sometimes.

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
とがあつて危険であり、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
具合であつた。 Conventionally, this has been prevented by placing the manhole cover on the hose or holding the hose by hand, but the former method is dangerous as it may cause the manhole cover to fly off, while the latter method is dangerous. This was a problem because one worker was unable to perform other important tasks.

〔問題点を解決するための手段〕 本考案はこの問題を解決するためになされたも
ので、マンホール蓋受枠の内側縁にホース保持具
を屈曲自在に設け、注排水中、ホースをそれに保
持させて、安全に消火作業又は補給作業が行なわ
れるようにしたものである。[Means for solving the problem] The present invention was made to solve this problem, and a hose holder is provided on the inner edge of the manhole cover frame so that the hose can be held there during pouring water. This is to ensure that fire extinguishing and replenishment work can be carried out safely.

〔実施例〕〔Example〕

図面は本考案の一実施例を示すもので、マンホ
ール蓋受枠本体１の内側に環状のホース保持具２

挿通し、ホース３が抜け出さないようにしたもの
である。 The drawing shows an embodiment of the present invention, in which an annular hose holder 2 is installed inside a manhole cover receiving frame body 1.
is attached so that it can be bent freely, and the hose 3 is inserted through it when the hose is in use, so that the hose 3 does not come out.

図示のものは環状のホース保持具２を屈曲自在

ンホールの昇降には支障はなく、またホース３の
挿入時にいろりの自在鈎と同様の作用により、固

止する。 The one shown has an annular hose holder 2 that can be bent freely, so if it is bent when not in use, there is no problem in going up and down the manhole, and when the hose 3 is inserted, it has the same effect as a flexible hook of various colors. This prevents the hose 3 from coming off better than if it were fixed.
