  • the support part 25 of the support tool 20 has a first engagement part 28 with which the temporary assembly member 29 engages.
  • the positioning tool 30 has a second engaging portion 32 with which the temporary assembly member 29 engages. According to this configuration, the support tool 20 can be positioned with respect to the positioning tool 30 by the temporary assembly member 29.
  • the anchor hole 26 of the support 20 is configured to also serve as the first engagement portion 28. According to this configuration, the support 20 can be configured to have a simple structure.
  • the fixing part 21 of the support 20 includes a fixing main body part 22 fixed to the formwork 2 and a connecting part 23.
  • the connecting portion 23 extends upward from the edge of the fixed main body portion 22 and connects the fixed main body portion 22 and the support portion 25 .
  • a gap S can be left between the upper surface 4A of the concrete 4 and the support part 25 in a state where the concrete 4 is placed in the formwork 2 (see FIG. 11). Therefore, the upper surface 4A of the concrete 4 under the support portion 25 can be easily leveled with a trowel.
  • Anchor bolt installation method includes first to fourth steps.
  • a plurality of supports 20 that support the anchor bolt 1 are temporarily assembled into a positioning tool 30.
  • the positioning tool 30 in which the supports 20 are temporarily assembled is arranged so that the plurality of supports 20 are arranged at predetermined positions with respect to the foundation 3.
  • the plurality of supports 20 are fixed to the formwork 2 of the foundation 3.
  • the positioning tool 30 is removed from the support tool 20.
  • the positioning tool 30 can be reused.
  • the positioner 30 can be taken to another site.
  • a plurality of positioning tools 30 were required.
  • the positioning tool 30 can be removed from the supporting tool 20 immediately after the supporting tool 20 is installed, so the number of positioning tools 30 used at one site can be reduced.
  • the support part 25 of the support tool 20 has a first engagement part 28 with which the temporary assembly member 29 engages.
  • the positioning tool 30 has a second engaging portion 32 with which the temporary assembly member 29 engages. According to this configuration, the support tool 20 can be positioned at a predetermined position with respect to the positioning tool 30 by the temporary assembly member 29.
  • the embodiment described above is an example of the form that the anchor bolt installation jig 10 and the anchor bolt installation method can take, and is not intended to limit the form.
  • the anchor bolt installation jig 10 and the anchor bolt installation method may take a form different from the form illustrated in the above embodiment.
  • An example of this is a configuration in which a part of the configuration of the embodiment is replaced, changed, or omitted, or a configuration in which a new configuration is added to the embodiment. Modifications of the embodiment are shown below.
  • the fixing part 21 of the support 20 may have a temporary fixing part 50.
  • the temporary fixing part 50 is configured to be temporarily fixed to the formwork 2.
  • the temporary fixing part 50 has a temporary fixing main body part 51 and two hanging parts 52.
  • the temporary fixing body part 51 is connected to the lower surface of the fixing body part 22.
  • the two hanging portions 52 are configured such that the frame plate 2A is inserted between the two hanging portions 52.
  • the two hanging parts 52 are provided at both ends of the temporarily fixed body part 51 in the second direction D2, and extend downward. The distance between the two hanging portions 52 is shorter than the width of the frame plate 2A of the formwork 2.
  • the frame plate 2A is inserted between the two hanging parts 52 of the temporary fixing part 50.
  • the support 20 can be temporarily fixed to the formwork 2.
  • the positioning tool 30 is supported by the plurality of supports 20 temporarily fixed to the frame board 2A. Therefore, after arranging the temporarily assembled positioning tool 30X at a predetermined position, the operator can adjust the position of the support tool 20 without supporting the positioning tool 30.
  • the fixed main body portion 22, the support portion 25, and the connecting portion 23 of the support device 20 are integrally configured.
  • the support 20 may be composed of a plurality of members.
  • the fixed main body portion 22 and the connecting portion 23 are configured as one member
  • the support portion 25 is configured as a separate member from the member including the fixed main body portion 22 and the connecting portion 23.
  • the support tool 20 may be made of resin. By constructing the support 20 from resin, the weight of the support 20 can be reduced.
