Abstract
A technique which can assemble a mandrel having a substantially cylindrical shape and being dividable into plurality of segments, which is used for manufacturing, for example, a fuselage of an aircraft, with high position accuracy and an easy manner. In a segment fastening step, a segment which is a fastened target is fastened to a specified fastening portion which is one of a plurality of fastening portions set along a pair of support rings placed to face each other. In a rotation step, before the segment fastening step, the support rings are rotated so that the specified fastening portion is located at an uppermost portion of the support rings. In the segment fastening step, the segment which is the fastened target is placed between the support rings and lifted vertically up to a height corresponding to the specified fastening portion and then fastened to the support rings.
