FIREPROOF TREATMENT TOOL USING FIRE COMPARTMENT WALL OPEN HOLE, AND FIREPROOF TREATMENT STRUCTURE
PROBLEM TO BE SOLVED: To enhance fixability and slip-off prevention performance of a fireproof treatment tool to an open hole, the fireproof treatment tool mounted at the open hole portion of a fire compartment wall.SOLUTION: In a fireproof treatment tool F, a cylindrical body 1 formed into a both-end opened shape is formed of a heat expansion material; a plurality of projections 2 is integrally provided with a predetermined interval on the cylindrical part outer peripheral surface of the cylindrical body 1; and by closely bonding the inner surface of an open hole H portion of a fire compartment wall with the plurality of projections 2 formed on the cylindrical part outer peripheral surface, a gap between the cylindrical body outer peripheral surface and the open hole inner peripheral surface is eliminated, and thereby flame, smoke and combustion air can be prevented from moving.
【課題】防火区画壁の貫通孔部分に装着される耐火処理具の貫通孔への固定性・脱落防止性を高めるようにした。【解決手段】耐火処理具(Ｆ)を、両端開放状に形成した円筒体(１)を熱膨張性素材で形成し、この円筒体(１)の筒部外周面に複数条の突起(２)を所定間隔隔てて一体に突設し、防火区画壁の貫通孔(H)部分の内面と円筒体(１)の筒部外周面に形成した複数条の突起(２)とを密着させることで円筒体外周面と貫通孔内周面との間の隙間をなくして、炎や煙、燃焼用空気の移動を抑制することができる。【選択図】 図１
