PROBLEM TO BE SOLVED: To provide a durable column-base metallic material which enables base concrete to be directly fixed by applying an anchor bolt and makes a column supported reliably. SOLUTION: Paired tripod plates 3 and 3 with a bent-shape cross section are installed in such a standing manner as to face each other while having an operating gap 8 for a nut 10, whereinto the anchor bolt 11 is screwed, on a base plate 2 formed with an assembling hole 1 whereinto the anchor bolt 11 installed protrusively in the base concrete 13 is inserted. A receiving plate 4, whereon the column 12 is placed for fixation, is installed on the tripod plates 3 and 3.
