Disc ring electrode support device

The present invention relates to the technical field of metal corrosion protection detection, and in particular relates to a disc ring electrode support device for solving the problem that a disc ring electrode is in poor contact with concrete surface during use of the disc ring electrode for detection of corrosion state of reinforcing steel bars in the bottom of a concrete beam slab. The disc ring electrode support device comprises a disc electrode fixture device, a contact force measuring device, a support bar, a contact force adjusting device and a disc electrode located in the disc electrode fixture device, wherein the disc electrode fixture device, the contact force measuring device, the support bar and the contact force adjusting device are sequentially connected. The disc ring electrode support device can achieve the effect of knowing and controlling of the contact force when the disc ring electrode is in contact with concrete surface, the problem that the disc ring electrode is in poor contact with the concrete surface during use of the disc ring electrode for detection of corrosion state of the reinforcing steel bars in the bottom of the concrete beam slab can be solved, and reinforcing steel bar corrosion state measurement accuracy and reproducibility can be improved.
