Steel bar concentricity detection tool and use method thereof

The invention relates to a steel bar concentricity detection tool comprising a detection rod and an angle meter, and the angle meter is arranged in the middle section of the detection rod. And scales for measuring the eccentric angle of the reinforcing steel bar are arranged on the angle meter . Compared with the prior art, the steel bar concentricity detection tool has the beneficial effects that the steel bar concentricity detection tool is simple in structure, easy and convenient to manufacture, easy to store and capable of rapidly and accurately completing steel bar concentricity detection. A clamping plate fixes a steel bar at one end on the detection rod, the steel bar at the other end pushes a baffle and a sliding block to measure the included angle between the two steel bars, and the operation is very simple; the detection tool is small in occupied area and convenient to store and move; the detection tool not only can detect the bending degree of the same reinforcing steel bar, but also can detect the
