利点がある。For example, the mold piece or the mold split piece forming the mold body in each embodiment is not necessarily divided into two and may be divided into three or more. Further, the mold body does not necessarily have to be divided or reduced in outer shape as long as it can be easily removed from the foundation. For example, it is made of a plastic material, etc., which has a moderate hardness and is deformable, and is removed from the foundation by deforming the mold body inward after forming the foundation, or a material with low adhesion to concrete, such as fluororesin. It is also possible to use a taper-shaped mold having a thin bottom portion, which can be easily pulled out from the foundation. However, the hole forming mold whose outer shape can be reduced has an advantage that the mold can be easily taken out from the base.

The pair of mold pieces 11, 11 may be expanded by the upper and lower end members 13, 14. At this time, the upper end member 13 may be expanded by the wedge 16, and the lower end member 14 may be expanded by providing a member similar to the wedge 16 of the upper end member 13. Therefore, the connecting member 15 in this case is simply the upper and lower end members 13 and 14 and the die support member 3.
It will only play the role of connecting 1. Further, in such a configuration, the connecting member 15 may be left attached to the lower end member 14 when the pair of mold pieces 11 and 11 are detached, and by doing so, an advantage that workability can be improved can be added. ..
