PROBLEM TO BE SOLVED: To provide an outside heat insulation fire resistant structure of an outer wall, capable of easily acquiring excellent heat insulation performance at an ordinary time and excellent fire resistance performance in a case of fire without making a heat insulation material thicker to increase the weight of the outer wall and without increasing the number of surface materials.SOLUTION: An outside heat insulation fire resistant structure 10 provided on an outer wall 11 of a wooden building and having both of heat insulation performance and fire resistance performance comprises: a structural face material 13 mounted on the outdoor side of outer wall structural members 12a, 12b, 12c forming a structural skeleton 12 of the outer wall 11; an easily combustible heat insulation material 14 closely mounted on the outdoor side of the structural face material 13; a hardly combustible inorganic heat insulation material 15 closely mounted on the outdoor side of the easily combustible heat insulation material 14; and a jacket material 16 mounted on the outdoor side of the hardly combustible inorganic heat insulation material 15. An interior material 19 is mounted on the indoor side of the outer wall structural members 12a, 12b, 12c. |
