PURPOSE: To prevent corrosion from being generated on a reinforced concrete structure by covering a concrete surface with metallic covering substance electrically conducted to reinforcing steel material in concrete with flame coating.
CONSTITUTION: A negative terminal 4 fitted on reinforcing steel material 3 in concrete is jointed to the positive terminal 5 of the metal of the same kind as flame coating metal covering substance 2 fitted on a flame coating surface, via a lead wire 6, and the metal covering substance 2 and the reinforcing steel material 3 are electrically conducted to each other. Prior to flame coating, a concrete surface is plastered, and strength in contact with the metal covering substance 2 is enhanced, and electric protection treatment is performed by using an external power source. Covering interrupting effect is displayed on the metal covering substance to be formed by flame-coating the concrete surface, and corrosion is prevented from being generated on a reinforced concrete structure.
