FIREPROOF MEASURE STRUCTURE OF FIRE COMPARTMENT WALL
To provide a fireproof measure structure of a fire compartment wall capable of pressure-welding a closing member to an outer surface of a penetration member without using a pressurization device.SOLUTION: In an open hole Wa of a fire compartment wall W, between an outer surface positioned in the open hole Wa and an inner surface of the open hole Wa in a wiring and piping material 11, a plurality of fireproof members 30 is housed so as to surround the wiring and piping material 11 and be laminated in a thickness direction, wherein the fireproof member comprises a flat plate-like base part 31 composed of foam chloroprene rubber containing expanded graphite. The fireproof member 30 is in a state of being compressed in the thickness direction, and is pressure-welded to an outer surface of the wiring and piping material 11 by reaction force which tries to restore from the compressed state to an original shape.SELECTED DRAWING: Figure 1
【課題】加圧装置を用いずに閉塞部材を貫通部材の外面に圧接させることができる防火区画壁の防火措置構造を提供すること。【解決手段】防火区画壁Ｗの貫通孔Ｗａにおいて、配線・配管材１１において貫通孔Ｗａ内に位置した外面と、貫通孔Ｗａの内面との間には、膨張黒鉛を含む発泡クロロプレンゴムからなる平板状の基部３１を備えた耐火部材３０が、配線・配管材１１を取り囲むとともに、厚み方向に複数積層された状態で収容されている。耐火部材３０は厚み方向に圧縮された状態にあり、圧縮された状態から原形状へ復帰しようとする反力により配線・配管材１１の外面に圧接している。【選択図】図１
