PROBLEM TO BE SOLVED: To provide a pile core control tool which allows easy alignment of pile cores. SOLUTION: A pair of bars 1a, 1b, which are pivoted to open/close freely, are arranged to be fixed together at almost right angles to each other. A pile core bar hole 11, into which a pile core bar 2 is inserted, is formed on the corner of the bars 1a, 1b fixed at almost right angles. A clearance core bar hole 12, into which a clearance core bar 3 is inserted, is formed on the bar 1a and on the bar 1b, where each clearance core bar hole 12 is located at the same distance from the pile core bar hole 11.
