PROBLEM TO BE SOLVED: To provide a fire-resistant structure of a building, which can restrain a gap from being made in a joint part of a finishing material in the case of a fire and which can exert excellent fire resistance efficiency.SOLUTION: In a fire-resistant structure B of a building, a plurality of finishing materials 3 with heat insulation properties is integrally attached to a steel backing material 1. A heat insulation layer 10 is provided in a section H2 between the steel backing material 1 and the finishing materials 3, and a heat absorber 11 is integrally provided on the finishing material 3 side of the steel backing material 1. Additionally, the finishing material 3 is arranged with a gap H2 between itself and the steel backing material 1, and a heat insulation layer 10 is formed as an air space. |
