CLOSING MEMBER AND CLOSING STRUCTURE OF OPEN HOLE
To provide a closing member capable of suppressing formation of a clearance extending linearly in a direction of penetrating a fire compartment wall in a case where a block part is compressively deformed in a thickness direction, and a closing structure of an open hole.SOLUTION: In a closing member 30, a plurality of compressively deformable block parts 34 are aligned in a longitudinal direction X, and all the block parts 34 are connected at one end side in a thickness direction Z of each block part 34. The closing member 30 is housed in a gap in an open hole in a state where a penetration direction and a depth direction Y of the open hole in a fire compartment wall coincide with each other. The closing member 30 has a slit 32 extending in the thickness direction Z and the depth direction Y between the side surfaces of the block parts 34 adjacent to each other in the longitudinal direction X. The side surfaces of the block part 34 that partitions the slit 32 intersect with a virtual surface M extending in the depth direction Y and the thickness direction Z.SELECTED DRAWING: Figure 2
【課題】ブロック部が厚さ方向に圧縮変形したときに、防火区画壁を貫通する方向へ一直線に延びる隙間が形成されることを抑制できる閉塞部材、及び貫通孔の閉塞構造を提供すること。【解決手段】閉塞部材３０において、圧縮変形可能な複数のブロック部３４が長手方向Ｘに並ぶとともに、各ブロック部３４の厚さ方向Ｚの一端側で全てのブロック部３４が繋がっている。閉塞部材３０は、防火区画壁における貫通孔の貫通方向と奥行方向Ｙが一致する状態で貫通孔内の空隙に収容される。閉塞部材３０は、長手方向Ｘに隣り合うブロック部３４の側面同士の間に、厚さ方向Ｚ及び奥行方向Ｙに延びるスリット３２を有する。スリット３２を区画するブロック部３４の側面は、奥行方向Ｙ及び厚さ方向Ｚに延びる仮想面Ｍに対し交差している。【選択図】図２
