耐火部材、耐火構造
Document Type and Number:
Japanese Patent JP7207959
Kind Code:
B2
Abstract:
To provide a fireproof member that is excellent in workability and can obtain a stable fireproof quality structure.SOLUTION: A fireproof member 1 is mainly composed of a foam body 3, a core member 5, a thermal expansion member 7, an incombustible material 9, and a bag body 11. The foam body 3 is an elastically deformable member, and is preferably a flammable sponge such as urethane foam, for example. The core member 5 is laminated on the foam body 3. The core material 5 can be easily rolled, and when it has a tubular shape, it secures rigidity in the axial direction of the tube. On the core member 5, the thermal expansion member 7 that is expanded by heat during a fire is laminated. An elastically deformable incombustible material 9 is laminated on the thermal expansion member 7. The foam body 3, core member 5, thermal expansion member 7, and incombustible material 9 are housed in the bag body 11, and are collectively covered by the bag body 11.SELECTED DRAWING: Figure 1
