FIREPROOF MEMBER, METHOD FOR MANUFACTURING FIREPROOF MEMBER AND FIREPROOF STRUCTURE
To provide a fireproof member and the like excellent in work efficiency and easily applicable to even a large-diameter through-hole.SOLUTION: A fireproof member 1 is constituted mainly of a fireproof material 3, an elastic member 7, and the like. The fireproof material 3 is an elastic and compressively deformable member. As the fireproof material 3, a fibrous member can be applied, for example, made from inorganic fiber glass wool, rock wool, or the like that is a shrinkable noncombustible material, fire retarding material, or the like whose volume is mostly occupied by air. Into the fireproof material 3, a thermal expansion member 5 is mixed. Small pieces of the thermal expansion members 5 are arranged in a distributed manner inside the fireproof material 3. The thermal expansion members 5 are members expanded by heat in the case of fire or the like.SELECTED DRAWING: Figure 2
【課題】 作業性に優れ、大口径の貫通孔へも容易に適用することが可能な防火部材等を提供する。【解決手段】 防火部材１は、主に、耐火材３、弾性部材７等から構成される。耐火材３は、弾力性のある圧縮変形可能な部材である。耐火材３としては、例えば、無機繊維系のガラスウールやロックウール等の繊維状部材であって、体積の多くを空気が占めており、収縮性を有する不燃材や難燃材等を適用可能である。耐火材３には、熱膨張部材５が混入している。熱膨張部材５の小片が耐火材３の内部に分散して配置される。熱膨張部材５は、火災時等の熱によって膨張する部材である【選択図】図２
