確実に閉塞することができる。(Effects of the Invention) As described in detail above, the present invention allows a cable or a pipe to pass through a wall penetration hole formed in a floor wall or a side wall, a balloon is placed in the wall penetration hole, and a fireproof material is placed inside the wall penetration hole. This is a simple method of filling the balloon with fireproof material and blocking the wall penetration, so it is a simple process of filling the balloon with fireproofing material using a pump etc.
It can easily close wall penetrations around cables, etc., and because it is filled with fireproof material, it fits the inner circumference of the wall penetration and the outer circumference of the cable, while allowing the balloon to fill every gap. By deforming it arbitrarily, the wall penetration "1" can be reliably closed.
