FIRE RESISTANT STRUCTURE AND FIREPROOF MEMBER
To provide a fire resistant structure and a fireproof member enabling an open hole at a partition part to be closed at a faster time.SOLUTION: A fire resistant structure comprises a partition part 11 having an open hole 11a; a resin pipe body 21 inserted into an open hole 11a; and a fire resistant member 31 arranged at an outer peripheral side of the resin pipe body 21. The fire resistant member 31 comprises a heat expansion material layer 32 that is thermally expanded through heating at the time of fire. The heat expansion material layer 32 has a first end part 32a and a second end part 32b that are both end parts along an axial direction LD of the resin pipe body 21. The first end part 32a is arranged between an outer peripheral surface of the resin pipe body 21 and an inner peripheral surface of the open hole 11a. The fireproof adiabatic material layer 33 has a constitution that an outer peripheral covering part 33a covering an outer peripheral side of the heat expansion material layer 32 and a first end surface covering part 33b covering an end surface of the first end part 32a are continuous in shape.SELECTED DRAWING: Figure 1
【課題】区画部の貫通孔をより早期に閉塞することを可能にした耐火構造及び耐火部材を提供する。【解決手段】耐火構造は、貫通孔１１ａを有する区画部１１と、貫通孔１１ａに挿通される樹脂製管体２１と、樹脂製管体２１の外周側に配置される耐火部材３１とを備える。耐火部材３１は、火災時の加熱により熱膨張する熱膨張材層３２と、熱膨張材層３２の外周側に配置される耐火断熱材層３３とを備える。熱膨張材層３２は、樹脂製管体２１の軸方向ＬＤに沿った両端部である第１端部３２ａ及び第２端部３２ｂを有する。第１端部３２ａは、樹脂製管体２１の外周面と貫通孔１１ａの内周面との間に配置される。耐火断熱材層３３は、熱膨張材層３２の外周側を覆う外周被覆部３３ａと第１端部３２ａの端面を覆う第１端面被覆部３３ｂとが連続した構成を有する。【選択図】図１
