The reinforcing bar spacer I is installed in parallel with the Pc steel material 31, and the stirrup 30 is gripped by each gripping portion 20 provided in advance so as to come to the installation position of the stirrup 30, and the stirrup in the axial direction of the steel material 31 is held. The installation interval of 30 is specified. Further, since two spacers I are installed in the upper tier and one in the lower tier, the stirrup 30 is not displaced or tilted when concrete is poured, and the intersection of the stirrup 30 and the Pc steel material 31 is bounded by a binding line. No need to fix. Concrete is placed in the form 40 in this state, but since the reinforcing bar spacer I is a steel member, it does not affect the quality of the Pc girder and can reinforce the strength of the girder as a steel material.
