本考案は、火災時におけるケーブル線路の延焼
防止および断熱効果を良好にし、更には延焼防止
剤の塗布層の剥離を容易に行なう場合に有用なケ
ーブル線路に関する。[Detailed description of the invention] (Technical field of the invention) The invention is useful for preventing the spread of fire and improving the heat insulation effect of cable lines in the event of a fire, and also for easily peeling off the coated layer of a fire spread preventive agent. Concerning cable lines.
（考案の技術的背景とその問題点）
一般に、原子力発電所、大型工場もしくはビル
等に布設されるケーブル線路には、ケーブルの延
焼防止を図るために防災処理が施されている。(Technical background of the invention and its problems) Generally, cable lines laid in nuclear power plants, large factories, buildings, etc. are treated with disaster prevention treatment to prevent the spread of fire on the cables.

られている。 Conventionally, such a cable line has been constructed by placing aluminum foil 3 or the like on the upper surface of a cable 2 laid out on a tray 1, as shown in FIG. (Unexamined Japanese Patent Publication No. 52-
50588), and one in which a sheet 8 wrapped in sand 7 is placed on a cable 6 laid in a trough 5 as shown in Figure 3 (Special Publication No. 48-43713). .

の変更や増設あるいは引替え工事を行なう場合、
塗布層４の剥離が困難であつた。 However, in the former case, since the fire spread preventive agent is not applied to the lower surface portion 9 and the side surface portions 10 of the cable tray 1, it is not possible to effectively prevent the spread of fire to the cable in these portions. The problem was that it did not provide good insulation to the cable. Furthermore, since both edges of the coating layer 4 of the fire spread prevention agent are in close contact with the side surface portions 10 of the cable tray 1, when changing, expanding, or replacing the cable route,
It was difficult to peel off the coating layer 4.
また、後者においては、ケーブルラツクに布設

ルラツクを垂直布設する場合においては砂の施工
が困難となる難点があつた。 Furthermore, the latter method had the disadvantage that it could not be applied to cable lines laid in cable racks. In other words, placing sand on top of the cables laid on the cable rack is limited by the load capacity of the cable rack, and since cable racks do not have an airtight structure like troughs, sand can easily escape in the event of a fire. The problem is that the sheet containing the sand disappears and the sand is released. Furthermore, when installing cable racks vertically, there was a problem in that sand construction was difficult.

The aim is to provide a cable line.
