PENETRATION STRUCTURE OF FIRE PROTECTION STRUCTURE AND ATTACHMENT METHOD OF FIREPROOF MEMBER
To provide a penetration structure of a fire protection structure which can suppress a fire spread without the necessity for adjusting an expansive fireproof material layer, and an attachment method of a fireproof member.SOLUTION: In a penetration structure of a fire protection structure W, a first fireproof member 111 and a second fireproof member 112 are attached to the outside of a heat insulation material 10 by being wound to the heat insulation material 10 so as to sandwich a thermal expansive fireproof material layer 22 by a base material 12 and the heat insulation material 10. In the first fireproof member 111, a first end part 15 intrudes into a penetration hole Wa, and a protrusion R is protruded from the fire protection structure W. A clearance between and among an inner face of the penetration hole Wa, the heat insulation member 10 located in the penetration hole Wa, and an outer face of a part of the first end part 15 is filled with mortar 19. In the thermal expansive fireproof material layer 22, a maximum expansion thickness from the heat-expanded base material 12 is thinner than a thickness of the heat insulation material 10.SELECTED DRAWING: Figure 2
【課題】膨張性耐火材層の調整を必要とせずに、火災の延焼を抑制できる防火構造体の貫通構造及び耐火部材の取付方法を提供すること。【解決手段】防火構造体Ｗの貫通構造において、第１耐火部材１１１及び第２耐火部材１１２は、基材１２と断熱材１０とで熱膨張性耐火材層２２を挟むように断熱材１０に巻回することで断熱材１０の外側に取り付けられている。第１耐火部材１１１は第１端部１５が貫通孔Ｗａに入り込むとともに、突出部Ｒが防火構造体Ｗから突出している。貫通孔Ｗａの内面と、貫通孔Ｗａ内に位置した断熱材１０及び第１端部１５の一部の外面との間はモルタル１９で埋められている。熱膨張性耐火材層２２は、熱膨張した際の基材１２からの最大膨張厚さが、断熱材１０の厚さよりも小さい。【選択図】図２
