PROBLEM TO BE SOLVED: To ensure that also a concrete member of a three-dimensional shape can be precast easily at a low cost. SOLUTION: In the method for precasting a concrete member structured of a longitudinal plate part and a crosswise plate part, connected to each other, reinforcements are arranged within outer frames 2 and 3 formed in one piece to the outer face of the longitudinal plate part and the outer face of the crosswise part. Further, a pair of side frames 4 and 5 of such a width as to correspond to the thickness of the concrete member to be molded, are arranged along the outer frames 2 and 3 and besides, in accordance with the frontage size W of the concrete member, and inner frames 6 and 7 are erected between the paired side frames 4 and 5. Thus a molding frame 1 is assembled and a ready-mixed concrete is cast into the molding frame 1 from a gap of the longitudinal plate part side of the molding frame 1 and consequently, the concrete member can be integrally molded. |
