    • A spalling failure prevention structure of a high-strength concrete member is provided to improve the quality of construction with the simple dry work, to apply the structure to the new or already constructed structure, and to enough secure the fire extinguishing time and the taking shelter hour by delaying that structure is broken down by preventing spalling failure in a fire. A spalling failure prevention structure of a high-strength concrete member is composed of a high-strength concrete member(10), an inorganic insulation layer(30) formed in the outer side of the high-strength concrete member, a fire resistant board(20) adhered to the outer surface of the inorganic insulation layer, a finish board(50) adhered to the outer surface of the inorganic insulation layer, and an air layer. The fire resistant board is formed at the thickness more than 15mm, and has the fire-resistance efficiency in which backside temperature is controlled at 200-450°C for three hours. The inorganic insulation layer is formed as the board type inorganic heat insulating material having glass surface or rock surface in order to have the thermal conductivity less than 00.1kcal /mh°C.
