PURPOSE:To effectively provide protection of reinforcing bars in concrete by adopting an internal electrode system for parts where a reinforcement quantity is small and a dispersion type or galvanic anode system for parts where the reinforcement quantity is large. CONSTITUTION:The internal electrode system for inserting the electrodes of an external power system from a concrete surface is adopted for the cross-beam side of a concrete structure where only the stirrups 3 (stirrups, web reinforcements, etc.) exist. The dispersion type electrode system or galvanic anode system of an external power source system which installs the electrodes over the entire surface of the concrete surfaces is adopted for the cross-beam bases densely arranged with main reinforcements 2. As a result, the effective and cost effective protection is attained over the entire part. The bases are coated with a conductive coating material over the entire surface of the concrete to form conductive coating film electrodes 5. Reference electrodes 6 for management of the protection are installed at the main reinforcements 2 and the stirrups 3 to measure poteintial. |
