PROBLEM TO BE SOLVED: To provide a construction method for a column-beam frame, which uses a prestressed concrete member, and which is more excellent in constructibility than a conventional method. SOLUTION: A prestressed concrete column member 20 constituting a column corresponding to two stories, and a prestressed concrete beam member 10 constituting a beam corresponding to two spans are used. The pair of prestressed concrete beam members 10 is joined to both side portions of a connection section 3A of the prestressed concrete column member 20. In this case, a main beam reinforcement protruding from an end of the one prestressed concrete beam member 10 passes through a through-hole of the prestressed concrete column member 20, and reaches the inside of the mechanical joint of the other prestressed concrete beam member 10; and the main beam reinforcements are joined together by means of the mechanical joint. Additionally, the pair of prestressed concrete column members 20 is joined to upper and lower portions of the connection section 3A of the prestressed concrete beam member 10. In this case, a main column reinforcement protruding from a member undersurface of the upper prestressed concrete column member 20 is inserted through a main-column-reinforcement through-hole of the prestressed concrete beam member 10; its leading end reaches the inside of the mechanical joint which is embedded in the upper portion of the lower prestressed concrete column member 20; and the main column reinforcements are joined together by means of the mechanical joint.
