〔産業上の利用分野〕
この発明は電カケープル、電話ケーブル、信号ケーブル
、同軸ケーブル、制御ケーブル、熱電対ケーブル等を複
数本束にしたいわゆるグループ・ケーブルの延焼防止法
に関する。[Detailed Description of the Invention] [Field of Industrial Application] This invention provides a method for preventing the spread of fire in so-called group cables, which are bundles of multiple power cables, telephone cables, signal cables, coaxial cables, control cables, thermocouple cables, etc. Regarding.
例えばコンビナートにおいては、ケーブルは電力供給用
として、又制御信号伝達用として重要な役目を負ってい
る。特に近年においては計算機例よる集中制御の進展と
共に、特に制御ケーブルの類および量が多くなっておシ
、コンビナートのすみずみまで張りめぐらされている。For example, in industrial complexes, cables play an important role in supplying power and transmitting control signals. Particularly in recent years, with the progress of centralized control using computers, the number and number of control cables has increased, and they are now spread throughout industrial complexes.
ところでこれらケーブルには絶縁材料として。By the way, these cables have an insulating material.
あるいけ外装材料として有機物（例えば合成樹脂ジが用
いられている。有機物は熱に弱く、それ自体がよく燃え
るためケーブルに沿って火災が拡大するおそれがある。Organic materials (for example, synthetic resins) are used as exterior materials for cables. Organic materials are sensitive to heat and burn easily, so there is a risk of a fire spreading along the cable.
しかも燃える場合に煙と有害ガス全発生する。Moreover, when it burns, it emits smoke and harmful gases.
さてケーブル火災は以上のようにきわめて危険であるが
、その危険度は単一のケーブルの場合よシも複数のケー
ブルを束ねたいわゆるグループ・ケーブルの場合が高い
。すなわち単一のケーブルの場合は燃えるのはそのケー
ブルのみであるが。Cable fires are extremely dangerous as described above, but the danger level is higher in so-called group cables that bundle multiple cables than in the case of a single cable. In other words, in the case of a single cable, only that cable will burn.
グループ・ケーブルの場合には各ケーブルが互いに絶縁
材料、外装材料を補給し合う現象を起こし。In the case of group cables, each cable replenishes insulating material and sheathing material to each other.
それ自身で発火した場合にせよ、他から火を受けて燃え
出した場合にせよ非常によく燃える。従ってその火勢は
個々のケーブルがある程度難燃化されていても強く、簡
単には消火しない。グループ・ケーブルは火災において
以上のようにきわめて危険で被害が広い範囲に及ぶおそ
ｎがあシ１通常の二酸化炭素消火器を用いても火を消す
ことが出来ない。It burns very well, whether it ignites on its own or when it catches fire from something else. Therefore, even if the individual cables are flame-retardant to some extent, the fire is strong and cannot be extinguished easily. Group cables are extremely dangerous in the event of a fire, as described above, and can cause damage over a wide area.Even with a normal carbon dioxide fire extinguisher, the fire cannot be extinguished.
すなわち消火器を作動させた場合のみ火勢は弱まるが、
その後再び火勢は強まる。そこで当山願人において、グ
ループ・ケーブルの弛焼金防ぐ方法として特開昭５２−
７８０９６号公報１％開昭５２−７８０９７号公報で示
すものを丁でに提案している。In other words, the fire will only weaken if the fire extinguisher is activated, but
After that, the fire intensified again. Therefore, Ganjin Toyama proposed a method for preventing loose burning of group cables in JP-A No. 52-
Publication No. 78096 1% What is shown in Publication No. 78097/1983 has been proposed exactly.
前記特開昭５２−７８０９６号公報に記載されているも
のは、グループ・ケーブルを、水が入れである容器の中
を通して延焼を防ぐようにしたものであるがこの方法で
はグループ・ケーブルの通る貫通孔部分の防水にかなシ
注意を払う必要がある。The method described in JP-A-52-78096 prevents the spread of fire by passing the group cable through a container containing water. Care must be taken to ensure that the holes are waterproof.
即ち複数本のケーブルを一つのチューブ内にまとめて大
きな一つのケーブルのような形にまとめである場合は防
水し易いが、電カケープル、電源ケーブル、制御ケーブ
ルといった場合に、複数本のケーブルが相互干渉をさけ
るために独立した形で貫通孔を通る場合にはケーブル同
志の接触部には空隙が生じ、その部分を防水することは
かなシやっかいな課題がある。In other words, it is easy to waterproof when multiple cables are combined into one large cable in one tube, but when multiple cables are connected to each other in the case of electric cables, power cables, control cables, etc. In order to avoid interference, when the cables pass through the through holes independently, a gap is created in the contact area between the cables, and it is difficult to waterproof that area.
このような点による防水の不具合は容器内の蒸発による
減少を招き、長期間の間に容器内の水がなくなって延焼
防止に役立たないことになる。Problems with waterproofing due to such points lead to water loss due to evaporation within the container, and the water in the container disappears over a long period of time, making it useless for preventing the spread of fire.
この発明はこのような従来の問題点の改善を図るもので
、グループ・ケーブルの長手方向の所定位誼に箱状体を
設けて、上記ケーブルの長手方向の一部が上記箱状体内
を通るようにすると共に。The present invention aims to improve such conventional problems, by providing a box-shaped body at a predetermined position in the longitudinal direction of the group cable, so that a part of the longitudinal direction of the cable passes through the box-shaped body.
