PROBLEM TO BE SOLVED: To provide a structure for temporarily fixing a PC girder of a column capital section, which enables a member for temporarily fixing the PC girder of the column capital section to be easily removed in a short period of time. SOLUTION: In the temporary fixation of the column capital section of the cantilever-erected PC girder, the PC girder 11 of the column capital section of a bridge to be cantilever-erected is temporarily fixed to a substructure 10 by means of a PC tendon 13 in such a manner that a temporary shoe 12 made of concrete is interposed between the PC girder and an upper end of the substructure 10. The temporary shoe 12 includes a large number of shear keys 24 which are integrally and protrusively provided on upper and lower, and fitted into the lower surface of the PC girder of the column capital section and the top surface of the substructure on the side of the top surface of the temporary shoe stone; and a horizontal shear force between the temporary shoe 12, and the PC girder 11 of the column capital section and the substructure 10 is resisted by the shear keys 24.
