PROBLEM TO BE SOLVED: To provide a coupling structure of column main reinforcements capable of forming an inexpensive reinforced concrete column with a simple structure. SOLUTION: A square column is used for a column 3. The column main reinforcements 4 comprise first column main reinforcements 5 disposed at four corners thereof and a plurality of second column main reinforcements 6 disposed between adjacent first column main reinforcements 5 at specified intervals. These reinforcements are formed so that multiple ones are connected to each other in the vertical direction and the total length thereof connected is short of the length of the members of the column 3. The upper and lower end parts 5a and 5b opposed in the vertical direction do not come into contact with each other, and the upper and lower end parts 6a and 6b do not come into contact with each other. The column main reinforcements 4 of such a structure are formed so that the first column main reinforcements 5 are disposed coaxially with each other in the vertical direction, and the opposed upper and lower end parts 5a and 5b are mechanically connected to each other through a mechanical coupling 8. Since the upper and lower end parts 6a and 6b are not connected to each other though the second column main reinforcements 6 are disposed coaxially with each other in the vertical direction, they form free ends.
