る。 Conventionally, when treating cable groups to prevent the spread of fire,
As shown in Fig. 1, the outer periphery of a group of cables is covered with a fireproofing material 2, but at this time, a large number of gaps 3 occur continuously in the longitudinal direction between the cables 1 or between the cables 1 and the fireproofing material 2. do. Additionally, when laying cable groups through through-holes in floors, walls, etc., a fireproofing material such as fireproof putty (hereinafter referred to as putty), asbestos, or rock wool is filled between the through-hole and the cable group as a fire prevention treatment. However, in this case, it is difficult to fill the through hole with the fireproofing material, and a void inevitably remains. Such voids also occur when a fireproofing material is filled between the tray and the cable group.
この様な空隙の存在により次の如き問題が生起
する。 The presence of such voids causes the following problems.
通電等によるケーブル発生熱、その他の熱の
放散を妨げる。 Prevents the dissipation of heat generated by cables due to energization, etc., and other heat.
火災時には、空隙に火炎が侵入してケーブル
の延焼が生起し、また空隙の煙突効果により延
焼が促進される。 In the event of a fire, flames enter the gap, causing the cable to spread, and the chimney effect of the gap accelerates the spread of the fire.

せる必要がある。 Furthermore, as a fireproofing material to fill the through hole,
Since rock wool, asbestos, putty, etc. are used, they have poor heat dissipation properties, and in power cables, the allowable current must be reduced, so it is necessary to guide heat outside the fireproofing material and dissipate it.

ある。 From this point of view, the inventors of the present invention have developed cables,
This idea was completed as a result of repeated research to create a cable line that eliminates the gaps that occur between fireproofing materials, trays, through holes, etc., and effectively dissipates the heat within the cable line to the outside. It is something.
従つて、本考案の第１の目的は、第１図に示し

A cable 1 is laid in a through hole provided in the cable 1, a string-like expandable graphite-containing foam fireproofing composition 4 is inserted along the length of the cable 1, and a fireproofing material 2 (for example, putty, etc.) is filled. This is what I did. Here, it is appropriate that the length of the string-like material of the expandable graphite-containing foam fireproofing composition be 2 to 5 times longer than the portion L covered with fireproofing putty or the like on both sides of the through hole. In this embodiment as well, a chip-like material may be used instead of a string-like material, and by using such a solid material, gaps can be easily filled in areas where it is difficult to fill with putty or the like.
以上説明したように本考案によると、
(1) 膨張性黒鉛含有発泡防火組成物を使用してい

ことができる。 As explained above, according to the present invention, (1) Since the foamed fireproofing composition containing expandable graphite is used, its good thermal conductivity allows the heat in the cable line to be effectively released to the outside, thereby increasing the power consumption. In the case of cables, the reduction in allowable current can be minimized.
(2) ひも状あるいはチツプ状の膨張性黒鉛含有発

る。(2) Since a foamed fireproofing composition containing expandable graphite in the form of strings or chips is used, the voids are effectively sealed even in areas where the voids cannot be filled with putty alone, and most of the voids are sealed. This prevents the spread of fire.
(3) 膨張性黒鉛含有発泡防火組成物を使用してい
るので、火災時には発泡、膨張することにより
ケーブルの焼細りが補われる。(3) Since it uses a foamed fire protection composition containing expandable graphite, it foams and expands in the event of a fire, thereby compensating for the thinning of the cable.
