PROBLEM TO BE SOLVED: To provide a method for reinforcing a structure of reinforced concrete construction, which enables construction without decreasing strength of a floor slab during the construction. SOLUTION: An anchor bolt 60 is driven into an undersurface of the floor slab 20 and a mesh reinforcement 50 is arranged along the undersurface of the floor slab 20. A mounting nut 40 with a rod-like steel material 42 mounted on the lateral surface of the hexagon nut is screwed to the anchor bolt 60, so that the steel material 42 can abut on a reinforcement 51, constituting the mesh reinforcement 50, from the other side of the floor slab 20. Then, shotcrete is sprayed on the undersurface of the floor slab 20. COPYRIGHT: (C)2010,JPO&INPIT |
