PROBLEM TO BE SOLVED: To provide a manufacturing method of a hollow thin shell column body and its shaping apparatus which can shorten the term of works and improve the productive capacity by making the working easy and reinforcing the quality of a beam pole. SOLUTION: An upper part steel mold 51 of an L shape has two or more arc leveling pads of a circular arc form at the external side. A lower part steel mold 52 of an L shape has two or more arc leveling pads of a circular arc form at the external side. Two definite shape leakage proof units 53, in which the thickness of a concrete molding is set by four sides, have openings to be filled in by transfixing working reinforcing steels 532 for a reinforcing steel basket at two opposing corners. Therefore, the molding shape of a four way-type long tube in a seal-up condition is composed, two opening edges at the front and rear of it and four interior molding surfaces are formed, the upper part steel mold 51 of the L shape and the lower part steel mold 52 of the L shape are assembled together and joined with the arc leveling pads of those external sides to form circular arc leveling pads 54 at the external side of an apparatus so that the form which switches the surface by a rotation is composed and the shaping for one surface is possible by one rotation.
