To arrange vertical reinforcements in a specified positional relation by integrally forming clamp pieces engaging with the vertical reinforcements at L-shaped both pieces and integrally forming engaging pieces fixing set pins for supporting a form in either piece.
Rods 12 arranged in a piece 1b are protruded to be nearly orthogonal to a long body 11 in which pieces 1a of respective corner panels 1 are connected to each other, and clamp pieces 13 for vertical reinforcements are provided in the rods 12 and the long body 11. Further, engaging pieces 14 for fixing set pins for supporting a form are provided in the long body 11 and the front ends of respective rods 12 are connected to each other by tie-rods 15. Lateral reinforcements 10 are arranged at every specified distance, and the vertical rods 18 are engaged with the clamp pieces 13 of the lateral reinforcements 10 to constitute a reinforced cage 19. In this time, large and small holes are selected in accordance with the thickness of the vertical reinforcements 18. Accordingly, the vertical reinforcements in specified positions and set pins for supporting a form can be easily set.
