PROBLEM TO BE SOLVED: To provide exterior insulation fireproof structure for wooden building which realizes low cost and easy operation and exerts excellent insulation efficiency.SOLUTION: The structure comprises: a structure surface material 24 attached on out side of structural member 2 constructed with wood; phenol form heat retaining plate 41 which is attached on outside surface of the structure surface material 24 and has thickness of 12 mm or more to 80 mm or less; and light bubble concrete panel 53 attached as exterior material on outside surface of the phenol form heat retaining plate 41. When density of the light bubble concrete panel 53 is d(kg/m), thickness of the light bubble concrete panel 53 is t (mm), and ignition loss value of the light bubble concrete panel 53 is α(wt%), 200≤d≤550, 45≤t≤100, 5≤α≤15, and 3000≤d×t×α÷100000≤30000 are accomplished.SELECTED DRAWING: Figure 2 |
