FIREPROOF MEMBER AND FIREPROOF STRUCTURE
To further improve the effect of suppressing the spread of fire by enhancing the sealing effect of a heat-expandable member.SOLUTION: A fireproof member 1 includes heat-expandable members 2A and 2B which are arranged at a distance from each other between the inner peripheral surface of a through hole 101 of a partition portion 100 and an outer peripheral surface of a pipe 102 and which are expanded by heat during a fire, and a holding member 5 made of an incombustible material which holds the heat-expandable members 2A and 2B.SELECTED DRAWING: Figure 4
【課題】熱膨張性部材による封止効果を高めて延焼抑制の効果をより一層向上させる。【解決手段】耐火部材１は、区画部１００の貫通孔１０１の内周面と配管１０２の外周面との間において互いに間隔をあけて配置され、火災時の熱によって膨張する熱膨張性部材２Ａ、２Ｂと、熱膨張性部材２Ａ、２Ｂを保持する不燃材料からなる保持部材５とを備えている。【選択図】図４
