FORM, RETAINING FRAME USING THE FORM AND MOLDING METHOD OF THE RETAINING FRAME

PROBLEM TO BE SOLVED: To provide a reinforcement post-installation type form and a retaining frame using this form, for efficiently arranging upper-lower stirrups and reinforcements. SOLUTION: A reinforcement support 1 between side frames is projected in a substantially L shape in the substantially longitudinal direction of the side frames when viewed from the side at the lower end 12b of vertical rods by vertically installing the vertical rods 12 between horizontal rods 11 and a connecting rod 10 in a position on the inside by a predetermined distance from the side frames 2 and 2. A support piece 13 for supporting the lower side of the lower side stirrup 4 mentioned later is bent, and projected in a substantially L shape in the substantially longitudinal direction in the same as the support piece 13 from the lateral outside in the upper end part or the midway part of the vertical rods 12. A locking piece 14 is arranged for similarly locking the side edge 41 of the lower side stirrup 4. COPYRIGHT: (C)2007,JPO&INPIT
