There is.

Next, a case will be described in which the anchor bolt 3 is embedded in the foundation concrete 1 using the anchor bolt embedding jig configured as described above. Formworks 2, 2 are placed in advance at locations where the foundation concrete 1 is to be constructed. Thereafter, the anchor bolt 3 is attached to the anchor plate 10 using the fitting 14. That is, among the plurality of insertion holes 10b formed in the anchor plate 10, the threaded portion 3a of the anchor bolt 3 is inserted into the insertion hole 10b that matches the center of the width of the formworks 2, 2, and the inserted threaded portion 3
A vinyl pipe 15 is inserted into a, and a nut 16 is screwed into the protruding portion of the vinyl pipe 15. As a result, anchor bolt 3
is attached to the anchor plate 10 in a suspended state by a fixture 14 consisting of a vinyl pipe 15 and a nut 16.

When the anchor bolt 3 is attached to the anchor plate 10 in this way, the lower part of the anchor bolt 3 is placed inside the formwork 2, 2, and the hook 10a of the anchor plate 10 is placed inside the formwork 2, 2.
The other end of the anchor plate 10 (the end opposite to the hook 10a) is placed on the other edge 2a. After this, anchor plate 10
A fixture 11 is attached to the other end and the edge 2a of the formwork 2. That is, the opening side of the fixture main body 12 is attached from the outside so as to sandwich the end of the anchor plate 10 and the edge 2a of the formwork 2, and the fixing lever 13 is rotated and fixed to the arc-shaped part of the fixing lever 13. Tool body 12
Anchor plate 10 and edge 2a of formwork 2 between
and sandwich it. Thereby, the anchor plate 10 is fixed to the formworks 2, 2.

When the anchor bolt 3 is fixed to the formwork 2, 2 in this way, first, the anchor bolt 3
The height may be adjusted by tightening the nut 16 of the fixture 14 at the upper end of the concrete, and then concrete may be poured into the formworks 2, 2 and allowed to harden. As a result, the foundation concrete 1 is constructed with the anchor bolts 3 embedded in predetermined locations.
