A spacer-cum-permanent mold 30 is held with a dam part 31 facing downward, and the dam part 31 is installed on a top end of the support post 51. An assembled reinforcement body 20 having a main reinforcement 21 and a shear auxiliary reinforcement 22 is installed on a reinforcement receiving part 32. A bottom mold 41 is fitted on the dam part 31 such that the dam part 31 closes an opening 41a formed on the bottom mold 41. A side mold 42 is erected on an edge part on both sides of the bottom mold 41.
