PROBLEM TO BE SOLVED: To provide a construction method of a PC beam to an existing column for improving the construction efficiency of column-beam coupling by minimizing the movement of a beam main reinforcement and the number of connections and simplifying the moving form of the beam main reinforcement. SOLUTION: By this construction method for a parial PC beam, a half PC beam 1 formed by previously putting the end of a beam upper end main reinforcement 2 aside to the vicinity of one beam end is erected between columns, and subsequently the orthogonal end 15 of the parial PC beam is dropped in the column on one side where the beam upper end main reinforcement is put aside to the vicinity of the beam end part. After that, the beam upper end main reinforcement 2 put aside to the vicinity of the beam end is moved until the orthogonal end 15 is dropped on the column on the other side of the parial PC beam 1, and then the orthogonal end 15 is dropped on the column the other side. After that, the moved beam upper end main reinforcement 2 is reversed and moved to a designated position within a column-beam joint area. COPYRIGHT: (C)2004,JPO&NCIPI
