FIRE-RESISTANT MEMBER AND FIRE-RESISTANT STRUCTURE
To improve construction workability on the site and shorten the construction time by providing a thermally expandable member between the outer peripheral surface of piping and the inner peripheral surface of a through hole.SOLUTION: A fire-resistant member 1 has: a thermally expandable member 2 that is disposed between the inner peripheral surface of a through hole and the outer peripheral surface of piping, and expands by heating at a fire; and a sealant 3, 4 that is fixed to the thermally expandable member 2 and is composed of an elastic material to cover a gap between the inner peripheral surface of the through hole and the outer peripheral surface of the piping.SELECTED DRAWING: Figure 4
【課題】配管の外周面と貫通孔の内周面との間に熱膨張性部材を設ける場合に、現場での施工作業性を良好にするとともに、施工時間を短くする。【解決手段】耐火部材１は、貫通孔の内周面と配管の外周面との間に配置され、火災時の熱によって膨張する熱膨張性部材２と、熱膨張性部材２に固定され、貫通孔の内周面と配管の外周面との隙間を覆う弾性材からなるシール材３、４とを備えている。【選択図】図４
