Claims

[Scope of utility model registration request]

When installing multiple foundation bolts on a foundation constructed in the ground, this jig is used to center each of the foundation bolts with respect to each bolt hole of the base frame to be fixed on the foundation. A plate having an inlet for a foundation construction agent and capable of fitting into a foundation construction hole, a hollow shaft that projects perpendicularly to the plate and into which each foundation bolt can be inserted, and each hollow shaft. a nut that is screwed onto the head of the foundation bolt that is inserted through the plate and holds the foundation bolt in a hanging state by engaging with the upper end of the hollow shaft; and a support rod capable of holding the plate in a fitted state in the foundation construction hole by extending its protrusion over the ground around the foundation construction hole, and each of said hollow shafts is connected to the center of the plate and the foundation construction hole. Planted on a foundation characterized by being arranged at a position that coincides with each bolt hole of the base frame when the center of the hole coincides, and having an axial length that can prevent misalignment of the foundation bolt. A jig for centering foundation bolts.
