PROBLEM TO BE SOLVED: To provide a separator for stacking which is capable of constructing a concrete foundation with high accuracy while achieving excellent workability.SOLUTION: In a separator 1 for stacking, elastic lock means are provided in an upper-stage outside lock piece 5 and a lower-stage outside lock piece 13. The elastic lock means provided in the upper-stage outside lock piece 5 is formed from an upper-stage protrusion piece 7 which protrudes substantially perpendicularly from a distal end region in the upper-stage outside lock piece 5 on an upper-stage inside lock piece 11 side towards the other end; and an upper-stage inclination piece 9 which extends towards the upper-stage inside lock piece 11 as it gets closer to a main body piece 3, while protruding from the upper-stage protrusion piece 7 towards the upper-stage inside lock piece 11. The elastic lock means provided in the lower-stage outside lock piece 13 is also similarly formed. The elastic lock means is elastically deformed by a flange 33 of a mold 30 and locks a rib 37 of the flange 33 with an elastic restoration force. |
