　ところで、建築業者が複数の建築物件に携わる場合がある。この場合において、基礎の施工が同時並行に実施されると、それぞれの現場で位置決め具のセットが必要となる。このため、建築業者は、複数の位置決め具のセットを予め用意しておく必要がある。多数の位置決め具のセットの在庫を保持することは、建築業者にとって管理上の負担となる。 By the way, a builder may be involved in multiple construction properties. In this case, if the foundation construction is carried out simultaneously, positioning tools will need to be set at each site. For this reason, the builder needs to prepare a plurality of sets of positioning tools in advance. Maintaining an inventory of a large number of positioning fixture sets poses an administrative burden to the builder.
　（１）上記課題を解決するアンカーボルト設置治具は、基礎にアンカーボルトを設置するアンカーボルト設置治具であって、前記アンカーボルトを支持する支持具と、基礎に対して前記支持具を位置決めする位置決め具とを備え、前記位置決め具は、前記位置決め具に複数の前記支持具が仮組されるように構成される。 (1) An anchor bolt installation jig that solves the above problem is an anchor bolt installation jig that installs an anchor bolt on a foundation, and includes a support for supporting the anchor bolt, and a positioning of the support with respect to the foundation. and a positioning tool, the positioning tool being configured such that the plurality of supports are temporarily assembled to the positioning tool.
　上記構成によれば、位置決め具に複数の支持具を所定位置に仮組した後、複数の支持具が仮組された状態で位置決め具を型枠に配置できる。このため、複数の支持具同士の位置関係が規定された状態で、複数の支持具を型枠に固定できる。そして、型枠に固定された複数の支持具から位置決め具を取り外すことができる。このため、取り外された位置決め具を使い回すことができる。このようなことから、アンカーボルト設置治具の在庫を削減できる。 According to the above configuration, after temporarily assembling the plurality of supports to the positioning tool at predetermined positions, the positioning tool can be placed in the formwork with the plurality of supports temporarily assembled. Therefore, the plurality of supports can be fixed to the formwork in a state where the positional relationship between the plurality of supports is defined. Then, the positioning tool can be removed from the plurality of supports fixed to the formwork. Therefore, the removed positioning tool can be reused. For this reason, the inventory of anchor bolt installation jigs can be reduced.
　（２）上記（１）に記載のアンカーボルト設置治具において、前記支持具は、構築される前記基礎の型枠に固定される固定部と、前記固定部から延びて前記アンカーボルトを支持する支持部とを有し、前記支持部は、前記アンカーボルトが挿通するアンカー孔と、前記支持具と前記位置決め具とを仮組するための仮組部材が係合する第１係合部とを有し、前記位置決め具は、前記仮組部材が係合する第２係合部と、前記基礎に対して前記位置決め具の位置を決める基準部とを有する。この構成によれば、仮組部材によって位置決め具に対して支持具を位置決めできる。 (2) In the anchor bolt installation jig according to (1) above, the support includes a fixing part fixed to the formwork of the foundation to be constructed, and extending from the fixing part to support the anchor bolt. a support part, the support part has an anchor hole through which the anchor bolt is inserted, and a first engagement part in which a temporary assembly member for temporarily assembling the support tool and the positioning tool engages. The positioning tool has a second engaging part with which the temporary assembly member engages, and a reference part that determines the position of the positioning tool with respect to the foundation. According to this configuration, the supporting tool can be positioned with respect to the positioning tool using the temporary assembly member.
　（３）上記（２）に記載のアンカーボルト設置治具において、前記支持具の前記アンカー孔は、前記第１係合部を兼ねるように構成される。この構成によれば、前記支持具をシンプルな構造に構成できる。 (3) In the anchor bolt installation jig according to (2) above, the anchor hole of the support is configured to also serve as the first engaging portion. According to this configuration, the support can be configured to have a simple structure.
　（４）上記（２）または（３）のいずれか１つに記載のアンカーボルト設置治具において、前記固定部は、前記型枠に固定される固定本体部と、前記固定本体部の端縁から上に延びて前記固定本体部と前記支持部とを連結する連結部とを備える。この構成によれば、型枠内にコンクリートを打設した状態において、コンクリートの上面と支持部との間に隙間を空けることができる。このため、支持部の下におけるコンクリートの上面をコテで均し易くできる。 (4) In the anchor bolt installation jig according to any one of (2) or (3) above, the fixing part includes a fixing body part fixed to the formwork and an edge of the fixing body part. and a connecting portion extending upward from the fixing body portion and connecting the fixed main body portion and the supporting portion. According to this configuration, a gap can be left between the upper surface of the concrete and the support part in a state where the concrete is placed in the formwork. Therefore, the upper surface of the concrete under the support part can be easily leveled with a trowel.
　（５）上記（２）～（４）のいずれか１つに記載のアンカーボルト設置治具において、前記固定部は、前記型枠に仮固定される仮固定部を有する。この構成によれば、基礎に対して、支持具が仮組された位置決め具を所定位置に配置したときに、支持具を型枠に仮固定できる。このため、支持具が仮組された位置決め具を所定位置に配置した後、作業者は、位置決め具を支持することなく、支持具の位置調整を行うことができる。 (5) In the anchor bolt installation jig according to any one of (2) to (4) above, the fixing part has a temporary fixing part that is temporarily fixed to the formwork. According to this configuration, when the positioning tool, in which the supporting tool is temporarily assembled, is placed at a predetermined position with respect to the foundation, the supporting tool can be temporarily fixed to the formwork. Therefore, after arranging the positioning tool with the support temporarily assembled at a predetermined position, the operator can adjust the position of the support without supporting the positioning tool.
　（６）上記課題を解決するアンカーボルト設置方法は、基礎の型枠にアンカーボルトを設置するアンカーボルト設置方法であって、前記アンカーボルトを支持する複数の支持具を位置決め具に仮組する第１工程と、基礎に対して所定位置に複数の前記支持具が配置されるように、前記支持具が仮組された前記位置決め具を配置する第２工程と、複数の前記支持具を前記基礎の前記型枠に固定する第３工程と、前記支持具から前記位置決め具を取り外す第４工程とを含む。 (6) An anchor bolt installation method that solves the above problems is an anchor bolt installation method in which the anchor bolt is installed in the formwork of the foundation, and the method includes temporarily assembling a plurality of supports supporting the anchor bolts to a positioning tool. a second step of arranging the positioning tool in which the supports are temporarily assembled so that the plurality of supports are arranged at predetermined positions with respect to the foundation; and a second step of placing the plurality of supports on the foundation. and a fourth step of removing the positioning tool from the support tool.
　この構成によれば、支持具を型枠に固定した後、位置決め具を使い回すことができる。例えば、位置決め具を他の現場に持って行くことができる。また、従来、基礎に複数のアンカーボルトを設置するために、複数の位置決め具が必要であったが、本技術によれば、支持具の設置後、直ぐに支持具から位置決め具を取り外すことができるため、１つの現場において使用する位置決め具の個数を削減できる。 According to this configuration, the positioning tool can be reused after the support tool is fixed to the formwork. For example, the positioner can be taken to other sites. Additionally, in the past, multiple positioning tools were required to install multiple anchor bolts on the foundation, but with this technology, the positioning tools can be removed from the support immediately after the support is installed. Therefore, the number of positioning tools used at one site can be reduced.
　（７）上記（６）に記載のアンカーボルト設置方法において、前記支持具は、前記型枠に固定される固定部と、前記固定部から延びて前記アンカーボルトを支持する支持部とを有し、前記支持部は、前記アンカーボルトが挿通するアンカー孔と、前記支持具と前記位置決め具とを仮組するための仮組部材が係合する第１係合部とを有し、前記位置決め具は、前記仮組部材が係合する第２係合部と、前記基礎に対して前記位置決め具の位置を決める基準部とを有する。この構成によれば、仮組部材によって位置決め具に対して所定位置に支持具を位置決めできる。 (7) In the anchor bolt installation method according to (6) above, the support includes a fixing part fixed to the formwork and a support part extending from the fixing part and supporting the anchor bolt. , the support part has an anchor hole through which the anchor bolt is inserted, and a first engagement part in which a temporary assembly member for temporarily assembling the support and the positioning tool engages, has a second engaging portion with which the temporary assembly member engages, and a reference portion that determines the position of the positioning tool with respect to the foundation. According to this configuration, the support tool can be positioned at a predetermined position with respect to the positioning tool using the temporary assembly member.
　本開示のアンカーボルト設置治具およびアンカーボルト設置方法によれば、アンカーボルト設置治具の在庫を削減できる。 According to the anchor bolt installation jig and anchor bolt installation method of the present disclosure, the inventory of anchor bolt installation jigs can be reduced.

　＜アンカーボルト設置治具＞
　図１～図１１を参照して、アンカーボルト設置治具１０を説明する。本実施形態において、アンカーボルト１は、構築される建築物の基礎３に対して設けられる。以下の説明では、記載を簡潔にするため、「構築される基礎３に対して」を単に「基礎３に対して」と記述する。したがって、以下に示す「基礎３に対して」の記述は、「構築される基礎３に対して」を意味する。具体的には、「構築される基礎３に対して」は、「構築される基礎３における基準線Ｌに対して」を意味する。 <Anchor bolt installation jig>
The anchor bolt installation jig 10 will be explained with reference to FIGS. 1 to 11. In this embodiment, the anchor bolt 1 is provided to the foundation 3 of the building to be constructed. In the following description, in order to simplify the description, "with respect to the foundation 3 to be constructed" will simply be written as "with respect to the foundation 3." Therefore, the description "with respect to the foundation 3" shown below means "with respect to the foundation 3 to be constructed." Specifically, "with respect to the foundation 3 to be constructed" means "with respect to the reference line L of the foundation 3 to be constructed."
　アンカーボルト設置治具１０は、建築物の基礎３にアンカーボルト１を設置するための治具である。基礎３は、コンクリート４および鉄筋５によって構成される。さらに、基礎３は、アンカーボルト１を備える。基礎３は、型枠２にコンクリート４を打設することによって形成される。ベタ基礎の場合、型枠２は、枠板２Ａによって構成される。枠板２Ａは、構築される基礎３の外周を囲むように設置される。枠板２Ａは、地盤７に支持棒２Ｃによって支持される（図６参照）。 The anchor bolt installation jig 10 is a jig for installing the anchor bolt 1 on the foundation 3 of a building. The foundation 3 is composed of concrete 4 and reinforcing bars 5. Furthermore, the foundation 3 is provided with an anchor bolt 1. The foundation 3 is formed by pouring concrete 4 into the formwork 2. In the case of a solid foundation, the formwork 2 is composed of frame plates 2A. The frame board 2A is installed so as to surround the outer periphery of the foundation 3 to be constructed. The frame board 2A is supported on the ground 7 by support rods 2C (see FIG. 6).
　アンカーボルト設置治具１０が適用される基礎３の例は限定されない。基礎３の例として、ベタ基礎、および、布基礎が挙げられる。本実施形態に示されるアンカーボルト設置治具１０は、ベタ基礎に好適に使用できる。 The example of the foundation 3 to which the anchor bolt installation jig 10 is applied is not limited. Examples of the foundation 3 include a solid foundation and a cloth foundation. The anchor bolt installation jig 10 shown in this embodiment can be suitably used for a solid foundation.
　布基礎の立ち上がり部に対応する型枠２は、互いに平行に設置される２個の枠板２Ａを備える。このため、２個の枠板２Ａの間に配置されるアンカーボルト１は、２個の枠板２Ａによって支持される支持部材で支持できる。これに対して、ベタ基礎の場合、基礎３を囲むように枠板２Ａが設置される。このため、アンカーボルト１を支持する支持具２０は、片持ち状態で枠板２Ａに固定される（図５および図９参照）。このように片持ち状態で枠板２Ａに支持される支持具２０を所定位置に配置するために、本実施形態に係るアンカーボルト設置治具１０が好適に使用できる。 The formwork 2 corresponding to the rising part of the cloth foundation includes two frame plates 2A installed parallel to each other. Therefore, the anchor bolt 1 placed between the two frame plates 2A can be supported by a support member supported by the two frame plates 2A. On the other hand, in the case of a solid foundation, the frame board 2A is installed so as to surround the foundation 3. Therefore, the support 20 that supports the anchor bolt 1 is fixed to the frame plate 2A in a cantilevered state (see FIGS. 5 and 9). The anchor bolt installation jig 10 according to this embodiment can be suitably used to arrange the support 20 supported by the frame plate 2A in a cantilevered manner at a predetermined position.
　アンカーボルト１は、アンカーボルト１の一部が基礎３の上面３Ａから露出するように設けられる（図１１参照）。アンカーボルト１の露出部１Ａ以外の部分１Ｂは、基礎３を構成するコンクリート４に埋められる。アンカーボルト１において露出した露出部１Ａは、基礎３に立てられる建築物本体の柱に結合される。 The anchor bolt 1 is provided so that a part of the anchor bolt 1 is exposed from the upper surface 3A of the foundation 3 (see FIG. 11). A portion 1B of the anchor bolt 1 other than the exposed portion 1A is buried in concrete 4 constituting the foundation 3. The exposed portion 1A of the anchor bolt 1 is coupled to a pillar of the building body erected on the foundation 3.
　一例では、アンカーボルト１は、基礎３の外周に沿って設置される。アンカーボルト１は、基礎３の型枠２が設置された後、かつ、型枠２にコンクリート４が打設される前の工程で、型枠２の内側に位置するように設置される。アンカーボルト設置治具１０は、この段階におけるアンカーボルト１の設置に使用される。以下、アンカーボルト設置治具１０の構成を説明する。 In one example, the anchor bolt 1 is installed along the outer periphery of the foundation 3. The anchor bolts 1 are installed so as to be located inside the formwork 2 in a step after the formwork 2 of the foundation 3 is installed and before concrete 4 is poured into the formwork 2. Anchor bolt installation jig 10 is used to install anchor bolt 1 at this stage. The configuration of the anchor bolt installation jig 10 will be described below.
　アンカーボルト設置治具１０は、アンカーボルト１を支持する支持具２０と、位置決め具３０とを備える（図３参照）。以下の説明において、平面視において、型枠２に沿う方向を第１方向Ｄ１といい、第１方向Ｄ１に直交する方向を第２方向Ｄ２という。 The anchor bolt installation jig 10 includes a support 20 that supports the anchor bolt 1 and a positioning tool 30 (see FIG. 3). In the following description, in plan view, the direction along the formwork 2 is referred to as a first direction D1, and the direction orthogonal to the first direction D1 is referred to as a second direction D2.
　＜支持具＞
　図１を参照して、支持具２０を説明する。支持具２０は、型枠２に固定される固定部２１と、支持部２５とを有する。 <Support>
The support 20 will be explained with reference to FIG. The support 20 has a fixing part 21 fixed to the formwork 2 and a support part 25.
　固定部２１は、固定本体部２２を有する。固定本体部２２は、型枠２に固定される。固定本体部２２は、型枠２の上面２Ｂに配置される。固定本体部２２の幅は、型枠２の幅と等しく、または、型枠２の幅よりも短い。固定本体部２２は、複数のビス孔２４を有する。ビス孔２４は長孔に構成される。ビス孔２４は、固定本体部２２が型枠２の上面２Ｂに配置された状態において、第２方向Ｄ２に延びる。ビス孔２４が長孔であることによって、型枠２に対して支持具２０が第２方向Ｄ２に位置調整できる。 The fixed part 21 has a fixed main body part 22. The fixed main body part 22 is fixed to the formwork 2. The fixed main body portion 22 is arranged on the upper surface 2B of the formwork 2. The width of the fixed body portion 22 is equal to or shorter than the width of the formwork 2. The fixed main body portion 22 has a plurality of screw holes 24. The screw hole 24 is formed into a long hole. The screw hole 24 extends in the second direction D2 when the fixed main body portion 22 is placed on the upper surface 2B of the formwork 2. Since the screw hole 24 is a long hole, the position of the support 20 with respect to the formwork 2 can be adjusted in the second direction D2.
　固定部２１は、さらに、連結部２３を有してもよい。連結部２３は、固定本体部２２と支持部２５とを連結する。連結部２３は、省略されてもよい。この場合、支持部２５は、固定本体部２２に直接に接続される。一例では、固定本体部２２と、支持部２５と、連結部２３とは、一体に構成される。具体的には、板金のプレス加工によって、固定本体部２２と、支持部２５と、連結部２３とが一体に形成される。 The fixing part 21 may further include a connecting part 23. The connecting portion 23 connects the fixed main body portion 22 and the support portion 25. The connecting portion 23 may be omitted. In this case, the support part 25 is directly connected to the fixed body part 22. In one example, the fixed main body portion 22, the support portion 25, and the connecting portion 23 are integrally configured. Specifically, the fixed main body portion 22, the support portion 25, and the connecting portion 23 are integrally formed by sheet metal press working.
　連結部２３は、第２方向Ｄ２における固定本体部２２の端から上に延びる。連結部２３は、次の目的のために設けられる。型枠２内にコンクリート４の打設時、コンクリート４を型枠２の上面２Ｂと同じ高さまで流し込む場合がある。このような場合のため、コンクリート４の上面４Ａと支持部２５との間に隙間Ｓが空くように、支持具２０に連結部２３が設けられる。隙間Ｓに、コンクリート４を均すコテが入るように、連結部２３の高さが設定される。また、連結部２３の高さＨは、アンカーボルト１においてコンクリート４から露出する露出部１Ａの高さを決める要素でもある。 The connecting portion 23 extends upward from the end of the fixed main body portion 22 in the second direction D2. The connecting portion 23 is provided for the following purpose. When pouring the concrete 4 into the formwork 2, the concrete 4 may be poured to the same height as the upper surface 2B of the formwork 2. For such a case, a connecting part 23 is provided on the support 20 so that a gap S is left between the upper surface 4A of the concrete 4 and the support part 25. The height of the connecting portion 23 is set so that a trowel for leveling the concrete 4 can fit into the gap S. Further, the height H of the connecting portion 23 is also a factor that determines the height of the exposed portion 1A of the anchor bolt 1 exposed from the concrete 4.
　支持部２５は、アンカーボルト１を支持する。支持部２５は、固定部２１から延びる。具体的には、側面視において、支持部２５は、連結部２３の上端から固定本体部２２に対して平行に延びる。平面視において、支持部２５は、連結部２３に対して固定本体部２２と反対側に延びる。 The support portion 25 supports the anchor bolt 1. The support portion 25 extends from the fixed portion 21 . Specifically, in side view, the support portion 25 extends from the upper end of the connecting portion 23 in parallel to the fixed main body portion 22. In plan view, the support portion 25 extends on the side opposite to the fixed main body portion 22 with respect to the connecting portion 23.
　支持部２５は、アンカーボルト１が挿通するアンカー孔２６を有する。一例では、支持部２５には、４個のアンカー孔２６とアンカー基準部２７とが設けられる。４個のアンカー孔２６は、アンカー基準部２７から等距離の位置に配置される。さらに、４個のアンカー孔２６は、４個のアンカー孔２６によって構成される形状が正方形となるように配置される。アンカー基準部２７は、支持具２０の基準位置を示すマークとしても使用される。アンカー基準部２７は、型枠２に支持具２０が固定された後、支持具２０の位置調整において使用される。例えば、アンカー基準部２７は、基礎３に対して張られる基準線Ｌ（例えば、水糸）と支持具２０との位置ずれを確認するときに、支持具２０の基準位置として使用される。アンカー基準部２７は、支持部２５を貫通する孔、窪み、または、刻印マークとして構成される。アンカー基準部２７は、目視できる大きさに構成される。 The support portion 25 has an anchor hole 26 through which the anchor bolt 1 is inserted. In one example, the support portion 25 is provided with four anchor holes 26 and an anchor reference portion 27. The four anchor holes 26 are arranged at positions equidistant from the anchor reference portion 27. Further, the four anchor holes 26 are arranged so that the shape formed by the four anchor holes 26 is a square. The anchor reference portion 27 is also used as a mark indicating the reference position of the support 20. The anchor reference portion 27 is used to adjust the position of the support 20 after the support 20 is fixed to the formwork 2. For example, the anchor reference portion 27 is used as a reference position for the support 20 when checking the positional deviation between the reference line L (for example, a water line) stretched over the foundation 3 and the support 20. The anchor reference portion 27 is configured as a hole, a depression, or an engraved mark passing through the support portion 25 . The anchor reference portion 27 is configured to have a size that can be visually observed.
　支持部２５は、さらに、第１係合部２８を有する。第１係合部２８は、仮組部材２９が係合する部分である。仮組部材２９は、支持具２０と位置決め具３０とを仮組するための部材である。仮組部材２９は、例えば、ボルト２９Ａである（図７参照）。仮組部材２９の他の例は、楔状のピンである。楔状のピンは「シノ」とも呼ばれる。第１係合部２８は、例えば、ボルト２９Ａが挿通する貫通孔として構成される。本実施形態では、アンカー孔２６が第１係合部２８を兼ねるように構成される。 The support portion 25 further includes a first engagement portion 28. The first engaging portion 28 is a portion with which the temporary assembly member 29 engages. The temporary assembly member 29 is a member for temporarily assembling the support tool 20 and the positioning tool 30. The temporary assembly member 29 is, for example, a bolt 29A (see FIG. 7). Another example of the temporary assembly member 29 is a wedge-shaped pin. The wedge-shaped pin is also called ``Shino''. The first engaging portion 28 is configured as a through hole into which the bolt 29A is inserted, for example. In this embodiment, the anchor hole 26 is configured to also serve as the first engaging portion 28.
　＜位置決め具＞
　図２および図３を参照して、位置決め具３０を説明する。位置決め具３０は、基礎３に対して支持具２０を位置決めするための道具である。具体的には、位置決め具３０は、基礎３の施工時に張られる基準線Ｌ（例えば、水糸）に対して複数の支持具２０を位置決めする。 <Positioning tool>
The positioning tool 30 will be explained with reference to FIGS. 2 and 3. The positioning tool 30 is a tool for positioning the support tool 20 with respect to the foundation 3. Specifically, the positioning tool 30 positions the plurality of supports 20 with respect to a reference line L (for example, a water line) stretched during construction of the foundation 3.
　位置決め具３０は、長尺の板材によって構成される。位置決め具３０の使用時、位置決め具３０は型枠２に沿うように配置される。 The positioning tool 30 is composed of a long plate. When using the positioning tool 30, the positioning tool 30 is placed along the formwork 2.
　位置決め具３０は、位置決め具３０の長手方向に延びる第１端３０Ａを有する。第１端３０Ａは、直線に延びる。位置決め具３０は、第１端３０Ａと反対側の第２端３０Ｂを有する。第２端３０Ｂは、第１端３０Ａと平行に延びる。 The positioning tool 30 has a first end 30A extending in the longitudinal direction of the positioning tool 30. The first end 30A extends in a straight line. The positioning tool 30 has a first end 30A and a second end 30B opposite to the first end 30A. The second end 30B extends parallel to the first end 30A.
　位置決め具３０は、位置決め具３０の所定位置に複数の支持具２０が仮組されるように構成される。位置決め具３０は、複数の仮組部３１を有する。仮組部３１は、支持具２０が仮組される部分である。複数の仮組部３１は、位置決め具３０の長手方向において、所定間隔を隔てて設けられる。一例では、複数の仮組部３１は、等間隔に設けられる。仮組部３１は、支持具２０の支持部２５の全体が接触できる大きさに構成される。 The positioning tool 30 is configured such that a plurality of supports 20 are temporarily assembled at predetermined positions of the positioning tool 30. The positioning tool 30 has a plurality of temporary assembly parts 31. The temporary assembly portion 31 is a portion where the support 20 is temporarily assembled.

The second engaging portion 32 and the reference portion 33 are provided in the temporary assembly portion 31.
　複数の第２係合部３２は、複数の第１係合部２８と同じ態様に構成される。本実施形態では、アンカー孔２６が第１係合部２８を兼ねる。そして、支持部２５には４個のアンカー孔２６が設けられるため、これと同様に、仮組部３１には、４個の第２係合部３２が設けられる。そして、４個の第２係合部３２の配置は、支持具２０の４個のアンカー孔２６の配置と同じ配置に構成される。具体的には、４個の第２係合部３２は、４個の第２係合部３２によって構成される形状が正方形となるように配置される。 The plurality of second engaging portions 32 are configured in the same manner as the plurality of first engaging portions 28. In this embodiment, the anchor hole 26 also serves as the first engaging portion 28. Since the support portion 25 is provided with four anchor holes 26, the temporary assembly portion 31 is similarly provided with four second engaging portions 32. The arrangement of the four second engaging portions 32 is the same as the arrangement of the four anchor holes 26 of the support 20. Specifically, the four second engaging parts 32 are arranged so that the shape formed by the four second engaging parts 32 is a square.
　図３に示されるように、位置決め具３０と支持具２０との仮組において、支持具２０は、位置決め具３０の下に配置される。具体的には、位置決め具３０の下面において仮組部３１に支持具２０の支持部２５が接触するように、支持具２０が配置される。このとき、４個の第１係合部２８と４個の第２係合部３２とがそれぞれに互いに重なるように、支持具２０が位置決め具３０に配置される。そして、第１係合部２８と第２係合部３２との連通孔にボルト２９Ａが挿通される。ボルト２９Ａにナット２９Ｂが取り付けられて、ナット２９Ｂが締め付けられることによって、位置決め具３０に支持具２０が仮組される。 As shown in FIG. 3, when the positioning tool 30 and the support tool 20 are temporarily assembled, the support tool 20 is placed under the positioning tool 30. Specifically, the support 20 is arranged so that the support part 25 of the support 20 contacts the temporary assembly part 31 on the lower surface of the positioning tool 30. At this time, the support 20 is arranged on the positioning tool 30 so that the four first engaging parts 28 and the four second engaging parts 32 overlap each other. Then, the bolt 29A is inserted into the communication hole between the first engaging part 28 and the second engaging part 32. The support 20 is temporarily assembled to the positioning tool 30 by attaching the nut 29B to the bolt 29A and tightening the nut 29B.
　位置決め具３０の基準部３３は、位置決め具３０の基準位置として使用される。具体的には、基準部３３は、型枠２に位置決め具３０が配置された後、基礎３に対して張られる基準線Ｌ（例えば、水糸）に対して位置決め具３０を位置決めする場合に、位置決め具３０の基準位置として使用される。 The reference portion 33 of the positioning tool 30 is used as a reference position of the positioning tool 30. Specifically, the reference part 33 is used when positioning the positioning tool 30 with respect to a reference line L (for example, a water line) stretched against the foundation 3 after the positioning tool 30 is placed on the formwork 2. , is used as a reference position for the positioning tool 30.
　基準部３３は、４個の第２係合部３２から等距離の位置に配置される。基準部３３は、位置決め具３０を貫通する貫通孔として構成される。基準部３３は、位置決め具３０と支持具２０とが仮組された状態において、基準部３３としての貫通孔を通して、支持具２０のアンカー基準部２７が視認できる大きさに構成される。 The reference part 33 is arranged at a position equidistant from the four second engaging parts 32. The reference portion 33 is configured as a through hole passing through the positioning tool 30. The reference portion 33 is configured to have a size that allows the anchor reference portion 27 of the support tool 20 to be visually recognized through the through hole serving as the reference portion 33 in a state where the positioning tool 30 and the support tool 20 are temporarily assembled.
　位置決め具３０は、軽量化のための孔３４が設けられてもよい。孔３４は、２個の仮組部３１の間に設けられる。位置決め具３０は、孔３４の替わりに、第２端３０Ｂを切り欠くように構成される切り欠き部を有してもよい。 The positioning tool 30 may be provided with a hole 34 for weight reduction. The hole 34 is provided between the two temporary assembly parts 31. The positioning tool 30 may have a notch configured to cut out the second end 30B instead of the hole 34.
　図４および図５を参照して、アンカーボルト設置治具１０の使い方を説明する。支持具２０を型枠２に取り付ける目的で、まず、位置決め具３０に支持具２０が仮組される。作業者は、支持具２０が仮組された位置決め具３０を用いて、支持具２０を型枠２の所定位置に取り付ける。 How to use the anchor bolt installation jig 10 will be explained with reference to FIGS. 4 and 5. In order to attach the support 20 to the formwork 2, the support 20 is first temporarily assembled to the positioning tool 30. The operator attaches the support 20 to a predetermined position on the formwork 2 using the positioning tool 30 on which the support 20 is temporarily assembled.
　基礎３が構築される地盤７には、アンカーボルト１を設置する位置を示すための基準線Ｌ（例えば、水糸）が張られる。基準線Ｌは、第１基準線Ｌ１と、第２基準線Ｌ２とを含む。第２基準線Ｌ２は、第１基準線Ｌ１に直交するように張られる。第１基準線Ｌ１と第２基準線Ｌ２とが交差する交点Ｐは、アンカーボルト１の設置基準点ＰＸに重なる。交点Ｐは、基礎３の出隅付近、または基礎３の入隅付近に位置する。 On the ground 7 on which the foundation 3 is constructed, a reference line L (for example, a water line) is stretched to indicate the position where the anchor bolt 1 is installed. The reference line L includes a first reference line L1 and a second reference line L2. The second reference line L2 is drawn perpendicular to the first reference line L1. An intersection P where the first reference line L1 and the second reference line L2 intersect overlaps the installation reference point PX of the anchor bolt 1. The intersection P is located near the outgoing corner of the foundation 3 or near the incoming corner of the foundation 3.
　図４に示されるように、支持具２０が仮組された位置決め具３０は、位置決め具３０の基準部３３が第１基準線Ｌ１と第２基準線Ｌ２との交点Ｐと重なり、かつ、位置決め具３０にある複数の基準部３３が第１基準線Ｌ１上に位置するように、配置される。そうすると、位置決め具３０に仮固定された複数の支持具２０が、基礎３に対して所定位置に配置される。 As shown in FIG. 4, the positioning tool 30 with the support 20 temporarily assembled is such that the reference part 33 of the positioning tool 30 overlaps the intersection P of the first reference line L1 and the second reference line L2, and The plurality of reference parts 33 on the tool 30 are arranged so as to be located on the first reference line L1. Then, the plurality of supports 20 temporarily fixed to the positioning tool 30 are arranged at predetermined positions with respect to the foundation 3.
　図５に示されるように、所定位置に配置された支持具２０は、ビス６によって枠板２Ａに固定される。また、位置決め具３０は、ビス６によって固定された支持具２０から取り外される。アンカーボルト１は、このように固定された支持具２０に取り付けられる。支持具２０は、基礎３に対して所定位置に配置されているため、支持具２０にアンカーボルト１を挿し込むだけで、基礎３に対してアンカーボルト１を所定位置に配置できる。 As shown in FIG. 5, the support 20 placed at a predetermined position is fixed to the frame plate 2A with screws 6. Further, the positioning tool 30 is removed from the support tool 20 fixed by the screws 6. The anchor bolt 1 is attached to the support 20 fixed in this way. Since the support 20 is arranged at a predetermined position with respect to the foundation 3, the anchor bolt 1 can be placed at a predetermined position with respect to the foundation 3 simply by inserting the anchor bolt 1 into the support 20.
　＜アンカーボルト設置方法＞
　図４および図６～図１１を参照して、アンカーボルト設置方法を説明する。アンカーボルト設置方法は、基礎３の型枠２にアンカーボルト１を設置する方法を示す。アンカーボルト設置方法は、基礎３の施工において使用される。 <Anchor bolt installation method>
An anchor bolt installation method will be described with reference to FIG. 4 and FIGS. 6 to 11. The anchor bolt installation method shows a method of installing the anchor bolt 1 in the formwork 2 of the foundation 3. The anchor bolt installation method is used in the construction of foundation 3.
　図６は、地盤７に型枠２が設置された状態を示す。地盤７には、溝８が設けられている。型枠２は、構築される基礎３を囲むように設置される。型枠２は、溝８の外側において、溝８に沿うように配置される。鉄筋５は、溝８に沿って設けられる。また、鉄筋５は、地盤７において基礎３が設けられる面全体に配筋される。 FIG. 6 shows the formwork 2 installed on the ground 7. A groove 8 is provided in the ground 7. The formwork 2 is installed so as to surround the foundation 3 to be constructed. The formwork 2 is arranged outside the groove 8 and along the groove 8. The reinforcing bars 5 are provided along the grooves 8. Further, the reinforcing bars 5 are arranged over the entire surface of the ground 7 where the foundation 3 is provided.
　図７、図８および図９は、アンカーボルト設置方法を示す図である。アンカーボルト設置方法は、少なくとも第１工程～第４工程を含む。 7, 8, and 9 are diagrams showing the anchor bolt installation method. The anchor bolt installation method includes at least first to fourth steps.
　図７に示されるように、第１工程では、複数の支持具２０を位置決め具３０に仮組する。具体的には、複数の支持具２０は、位置決め具３０の下に配置される（図３および図７参照）。位置決め具３０の下面において仮組部３１に支持具２０の支持部２５が接触するように、支持具２０が配置される。４個の第１係合部２８と４個の第２係合部３２とがそれぞれに互いに重なるように配置される（図３参照）。そして、上述のように、位置決め具３０と支持具２０とが仮組される。 As shown in FIG. 7, in the first step, a plurality of supports 20 are temporarily assembled into a positioning tool 30. Specifically, the plurality of supports 20 are arranged under the positioning tool 30 (see FIGS. 3 and 7). The support 20 is arranged so that the support part 25 of the support 20 contacts the temporary assembly part 31 on the lower surface of the positioning tool 30. The four first engaging parts 28 and the four second engaging parts 32 are arranged so as to overlap each other (see FIG. 3). Then, as described above, the positioning tool 30 and the support tool 20 are temporarily assembled.
　第２工程では、基礎３に対して所定位置に複数の支持具２０が配置されるように、支持具２０が仮組された位置決め具３０（以下、仮組の位置決め具３０Ｘ）を配置する。具体的には、基礎３が設けられる地盤７に張られた基準線Ｌに対して、仮組の位置決め具３０Ｘが位置決めされる（図４参照）。 In the second step, a positioning tool 30 (hereinafter referred to as a temporarily assembled positioning tool 30X) 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. Specifically, the temporary assembly positioning tool 30X is positioned with respect to a reference line L stretched on the ground 7 on which the foundation 3 is provided (see FIG. 4).
　図４に示されるように、基礎３が設けられる地盤７には、基準線Ｌ（例えば、水糸）が張られる。第１基準線Ｌ１は、第２方向Ｄ２に型枠２から所定距離だけ離れるように、かつ、型枠２に沿うように張られている。また、第２基準線Ｌ２は、第１基準線Ｌ１に直交し、かつ、第１基準線Ｌ１上にあるアンカーボルト１の設置基準点ＰＸを通るように張られる。第１基準線Ｌ１と第２基準線Ｌ２との交点Ｐは、アンカーボルト１の設置基準点ＰＸと重なる。アンカーボルト１の設置基準点ＰＸの全てに第２基準線Ｌ２が設けると、地盤７に張られる基準線Ｌの数が過多になり、コンクリート４の均し作業に支障をきたすため、幾つかの第２基準線Ｌ２は省略される。 As shown in FIG. 4, a reference line L (for example, a water line) is stretched on the ground 7 on which the foundation 3 is provided. The first reference line L1 is stretched along the formwork 2 and apart from the formwork 2 by a predetermined distance in the second direction D2. Further, the second reference line L2 is perpendicular to the first reference line L1 and is stretched so as to pass through the installation reference point PX of the anchor bolt 1 located on the first reference line L1. An intersection P between the first reference line L1 and the second reference line L2 overlaps with the installation reference point PX of the anchor bolt 1. If the second reference line L2 is provided at all the installation reference points PX of the anchor bolts 1, the number of reference lines L stretched on the ground 7 will be excessive, which will hinder the leveling work of the concrete 4. The second reference line L2 is omitted.
　仮組の位置決め具３０Ｘは、位置決め具３０の端部にある基準部３３が第１基準線Ｌ１と第２基準線Ｌ２との交点Ｐと重なり、かつ、位置決め具３０にある複数の基準部３３が第１基準線Ｌ１上に位置するように、配置される。これによって、位置決め具３０に仮組された複数の支持具２０が、基準線Ｌに対して所定位置に配置される。このとき、仮組の位置決め具３０Ｘの両端は、作業者によって支持されている。 The temporarily assembled positioning tool 30X has a reference section 33 at the end of the positioning tool 30 that overlaps the intersection P of the first reference line L1 and the second reference line L2, and a plurality of reference sections 33 on the positioning tool 30. is positioned on the first reference line L1. As a result, the plurality of supports 20 temporarily assembled to the positioning tool 30 are arranged at predetermined positions with respect to the reference line L. At this time, both ends of the temporarily assembled positioning tool 30X are supported by the operator.
　図８に示されるように、第３工程において、複数の支持具２０を基礎３の型枠２に固定する。具体的には、仮組の位置決め具３０Ｘが基礎３に対して所定位置に配置された状態において、位置決め具３０に仮組された状態にある支持具２０の固定部２１をビス６で型枠２に固定する。 As shown in FIG. 8, in the third step, a plurality of supports 20 are fixed to the formwork 2 of the foundation 3. Specifically, in a state where the temporarily assembled positioning tool 30X is placed at a predetermined position with respect to the foundation 3, the fixing part 21 of the support 20 temporarily assembled to the positioning tool 30 is fixed to the formwork with screws 6. Fixed at 2.
　図９に示されるように、第４工程では、支持具２０から位置決め具３０を取り外す。支持具２０が取り外された位置決め具３０は、他の支持具２０の仮組に使用できる。 As shown in FIG. 9, in the fourth step, the positioning tool 30 is removed from the support tool 20. The positioning tool 30 from which the support 20 has been removed can be used for temporary assembly of other supports 20.
　図１０に示されるように、型枠２に固定された支持具２０には、アンカーボルト１が取り付けられる。具体的には、アンカー孔２６にアンカーボルト１が挿通される（図５参照）。そして、アンカーボルト１は、ナット３９によって支持具２０に固定される。 As shown in FIG. 10, anchor bolts 1 are attached to supports 20 fixed to formwork 2. Specifically, the anchor bolt 1 is inserted into the anchor hole 26 (see FIG. 5). The anchor bolt 1 is then fixed to the support 20 by a nut 39.
　その後、図１１に示されるように、アンカーボルト１の設置後、型枠２内にコンクリート４が打設される。この後、コンクリート４の表面はトンボまたはコテによって均される。コンクリート４の表面において、支持具２０の下の部分はコテを使って均される。 Thereafter, as shown in FIG. 11, after the anchor bolts 1 are installed, concrete 4 is poured into the formwork 2. After this, the surface of the concrete 4 is leveled with a dragonfly or a trowel. On the surface of the concrete 4, the portion below the support 20 is leveled using a trowel.
　＜実施形態の作用＞
　本実施形態の作用を説明する。従来、アンカーボルト１は、型枠２に固定されるアンカー支持具によって支持されている。これらアンカー支持具は、アンカーボルト１を設置するところに固定される。このため、基礎３の外周に沿って多数のアンカーボルト１が設けられる場合、アンカー支持具の位置決めに多大な時間を要している。 <Action of the embodiment>
The operation of this embodiment will be explained. Conventionally, the anchor bolt 1 is supported by an anchor support fixed to the formwork 2. These anchor supports are fixed where the anchor bolt 1 is installed. For this reason, when a large number of anchor bolts 1 are provided along the outer periphery of the foundation 3, it takes a lot of time to position the anchor supports.
　本実施形態では、複数の支持具２０は、位置決め具３０の所定位置にある仮組部３１に仮組される。このとき、複数の支持具２０同士の位置関係は、支持具２０を位置決め具３０の仮組部３１に仮組することによって、正確に規定される。このため、位置決め具３０に仮組された何れか１つの支持具２０を基礎３における所定位置に配置し、かつ、位置決め具３０を基礎３に対して所定の向きに配置することによって、他の支持具２０も基礎３に対して所定位置に配置される。具体的には、上述のように、位置決め具３０の端部にある基準部３３が第１基準線Ｌ１と第２基準線Ｌ２との交点Ｐと重なり、かつ、位置決め具３０にある複数の基準部３３が第１基準線Ｌ１上に位置するように、仮組の位置決め具３０Ｘを配置する。これによって、位置決め具３０に仮組された複数の支持具２０が、基準線Ｌに対して所定位置に配置される。このように、基礎３に対して複数の支持具２０を実質的に同時に所定位置に配置できる。これによって、支持具２０の位置決め作業の作業時間を短縮できる。 In this embodiment, the plurality of supports 20 are temporarily assembled into a temporary assembly section 31 located at a predetermined position of the positioning tool 30. At this time, the positional relationship between the plurality of supports 20 is accurately defined by temporarily assembling the supports 20 to the temporary assembly section 31 of the positioning tool 30. Therefore, by arranging any one of the supports 20 temporarily assembled to the positioning tool 30 at a predetermined position on the foundation 3 and arranging the positioning tool 30 in a predetermined direction with respect to the foundation 3, other The support 20 is also placed in a predetermined position relative to the foundation 3. Specifically, as described above, the reference portion 33 at the end of the positioning tool 30 overlaps the intersection P of the first reference line L1 and the second reference line L2, and The temporary assembly positioning tool 30X is arranged so that the portion 33 is located on the first reference line L1. As a result, the plurality of supports 20 temporarily assembled to the positioning tool 30 are arranged at predetermined positions with respect to the reference line L. In this way, a plurality of supports 20 can be placed in position with respect to the foundation 3 substantially simultaneously. Thereby, the working time for positioning the support 20 can be shortened.
　加えて、位置決め具３０は、支持具２０が型枠２に固定された後、支持具２０から取り外される。このため、位置決め具３０を使い回すことが可能である。例えば、１つの建築現場において、１個～数個の位置決め具３０を使い回すことによって、多数のアンカーボルト１を基礎３に対して設置できる。また、建築業者が、複数の建築物件について同時並行に施工している場合、１つの建築物件で使用し終わった位置決め具３０を他の現場に持って行くことができる。 In addition, the positioning tool 30 is removed from the support tool 20 after the support tool 20 is fixed to the formwork 2. Therefore, it is possible to reuse the positioning tool 30. For example, a large number of anchor bolts 1 can be installed on the foundation 3 at one construction site by reusing one to several positioning tools 30. Further, when a builder is constructing multiple buildings at the same time, the positioning tool 30 that has been used for one building can be taken to another site.
　＜本実施形態の効果＞
　本実施形態の効果を説明する。
　（１）アンカーボルト設置治具１０は、アンカーボルト１を支持する支持具２０と、基礎３に対して支持具２０を位置決めする位置決め具３０とを備える。位置決め具３０は、位置決め具３０に複数の支持具２０が仮組されるように構成される。 <Effects of this embodiment>
The effects of this embodiment will be explained.
(1) The anchor bolt installation jig 10 includes a support 20 that supports the anchor bolt 1 and a positioning tool 30 that positions the support 20 with respect to the foundation 3. The positioning tool 30 is configured such that the plurality of supports 20 are temporarily assembled to the positioning tool 30.
　上記構成によれば、位置決め具３０に複数の支持具２０を所定位置に仮組した後、複数の支持具２０が仮組された状態で位置決め具３０を型枠２に配置できる。このため、複数の支持具２０同士の位置関係が規定された状態で、複数の支持具２０を型枠２に固定できる。その後、型枠２に固定された複数の支持具２０から位置決め具３０を取り外すことができる。このため、取り外された位置決め具３０を他の現場に持って行くことができる。従来の位置決め具は、基礎３のコンクリート４が固まるまでアンカーボルト１を支持する治具として使用されるため、位置決め具３０の使い回しの回転率を高くできない。この点、上記構成によれば、支持具２０を型枠２に固定した後、位置決め具３０を使い回すことができる。例えば、位置決め具３０を他の現場に持って行くことができる。 According to the above configuration, after the plurality of supports 20 are temporarily assembled to the positioning tool 30 at predetermined positions, the positioning tool 30 can be placed in the formwork 2 in a state where the plurality of supports 20 are temporarily assembled. Therefore, the plurality of supports 20 can be fixed to the formwork 2 in a state where the positional relationship between the plurality of supports 20 is defined. After that, the positioning tool 30 can be removed from the plurality of supports 20 fixed to the formwork 2. Therefore, the removed positioning tool 30 can be taken to another site. Since the conventional positioning tool is used as a jig to support the anchor bolt 1 until the concrete 4 of the foundation 3 hardens, the rotation rate of the positioning tool 30 cannot be increased. In this regard, according to the above configuration, the positioning tool 30 can be reused after the support tool 20 is fixed to the formwork 2. For example, the positioner 30 can be taken to another site.
　また、従来、基礎３に多数のアンカーボルト１を設置するために、複数の位置決め具３０が必要であったが、本構成によれば、次の効果がある。支持具２０の設置後、直ぐに支持具２０から位置決め具３０を取り外すことができる。そして、１つの現場においても、位置決め具３０を使い回すことができる。このため、１つの現場において使用する位置決め具３０の個数を削減できる。この点でも、建築業者は、アンカーボルト設置治具１０の在庫を削減できる。特に、位置決め具３０の在庫を削減できる。 Furthermore, in the past, a plurality of positioning tools 30 were required in order to install a large number of anchor bolts 1 on the foundation 3, but this configuration has the following effects. After installing the support 20, the positioning tool 30 can be removed from the support 20 immediately. Furthermore, the positioning tool 30 can be reused even at one site. Therefore, the number of positioning tools 30 used at one site can be reduced. In this respect as well, the builder can reduce the inventory of anchor bolt installation jigs 10. In particular, the inventory of positioning tools 30 can be reduced.
　（２）支持具２０の支持部２５は、仮組部材２９が係合する第１係合部２８を有する。位置決め具３０は、仮組部材２９が係合する第２係合部３２を有する。この構成によれば、仮組部材２９によって位置決め具３０に対して支持具２０を位置決めできる。 (2) 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.
　（３）支持具２０のアンカー孔２６は、第１係合部２８を兼ねるように構成される。この構成によれば、支持具２０をシンプルな構造に構成できる。 (3) 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.
　（４）支持具２０の固定部２１は、型枠２に固定される固定本体部２２と、連結部２３とを備える。連結部２３は、固定本体部２２の端縁から上に延びて固定本体部２２と支持部２５とを連結する。この構成によれば、型枠２内にコンクリート４を打設した状態において、コンクリート４の上面４Ａと支持部２５との間に隙間Ｓを空けることができる（図１１参照）。このため、支持部２５の下におけるコンクリート４の上面４Ａをコテで均し易くできる。 (4) 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 . According to this configuration, 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.
　（５）アンカーボルト設置方法は、第１工程～第４工程を含む。第１工程では、アンカーボルト１を支持する複数の支持具２０を位置決め具３０に仮組する。第２工程では、基礎３に対して所定位置に複数の支持具２０が配置されるように、支持具２０が仮組された位置決め具３０を配置する。第３工程では、複数の支持具２０を基礎３の型枠２に固定する。第４工程では、支持具２０から位置決め具３０を取り外す。 (5) Anchor bolt installation method includes first to fourth steps. In the first step, a plurality of supports 20 that support the anchor bolt 1 are temporarily assembled into a positioning tool 30. In the second step, 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. In the third step, the plurality of supports 20 are fixed to the formwork 2 of the foundation 3. In the fourth step, the positioning tool 30 is removed from the support tool 20.
　この構成によれば、支持具２０を型枠２に固定した後、位置決め具３０を使い回すことができる。例えば、位置決め具３０を他の現場に持って行くことができる。また、従来、基礎３に複数のアンカーボルト１を設置するために、複数の位置決め具３０が必要であった。この点、本技術によれば、支持具２０の設置後、直ぐに支持具２０から位置決め具３０を取り外すことができるため、１つの現場において使用する位置決め具３０の個数を削減できる。 According to this configuration, after the support 20 is fixed to the formwork 2, the positioning tool 30 can be reused. For example, the positioner 30 can be taken to another site. Furthermore, conventionally, in order to install a plurality of anchor bolts 1 on the foundation 3, a plurality of positioning tools 30 were required. In this regard, according to the present technology, 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.
　（６）アンカーボルト設置方法において、支持具２０の支持部２５は、仮組部材２９が係合する第１係合部２８を有する。位置決め具３０は、仮組部材２９が係合する第２係合部３２を有する。この構成によれば、仮組部材２９によって位置決め具３０に対して所定位置に支持具２０を位置決めできる。 (6) In the anchor bolt installation method, 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.
　＜変形例＞
　上記実施形態は、アンカーボルト設置治具１０、および、アンカーボルト設置方法が取り得る形態の例示であり、その形態を制限することを意図していない。アンカーボルト設置治具１０、および、アンカーボルト設置方法は、上記実施形態に例示された形態とは異なる形態を取り得る。その例は、実施形態の構成の一部を置換、変更、省略した形態、または、実施形態に新たな構成を付加した形態である。以下に実施形態の変形例を示す。 <Modified example>
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.
　・図１２に示されるように、支持具２０の固定部２１は、仮固定部５０を有してもよい。仮固定部５０は、型枠２に仮固定されるように構成される。仮固定部５０は、仮固定本体部５１と、２個の下垂部５２とを有する。仮固定本体部５１は、固定本体部２２の下面に接続される。２個の下垂部５２は、２個の下垂部５２の間に枠板２Ａが入るように構成される。２個の下垂部５２は、第２方向Ｄ２において仮固定本体部５１の両端それぞれに設けられ、下方に延びる。２個の下垂部５２の間隔距離は、型枠２の枠板２Ａの幅よりも短い。 - As shown in FIG. 12, 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.
　このような支持具２０によれば、基礎３に対して、仮組の位置決め具３０Ｘが所定位置に配置するときに、仮固定部５０の２個の下垂部５２の間に枠板２Ａを入れることによって、支持具２０を型枠２に仮固定できる。そうすると、位置決め具３０は、枠板２Ａに仮固定された複数に支持具２０によって支持される。このため、仮組の位置決め具３０Ｘを所定位置に配置した後、作業者は、位置決め具３０を支持することなく、支持具２０の位置調整を行うことができる。 According to such a support 20, when the temporarily assembled positioning tool 30X is placed in a predetermined position with respect to the foundation 3, the frame plate 2A is inserted between the two hanging parts 52 of the temporary fixing part 50. By doing so, the support 20 can be temporarily fixed to the formwork 2. Then, 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.
　・上記実施形態では、支持具２０の固定本体部２２と支持部２５と連結部２３とは一体に構成される。これに対して、支持具２０は、複数の部材によって構成されてもよい。例えば、固定本体部２２と連結部２３とが１個の部材で構成され、かつ、支持部２５は、固定本体部２２と連結部２３とを含む部材と別部材で構成される。 - In the above embodiment, the fixed main body portion 22, the support portion 25, and the connecting portion 23 of the support device 20 are integrally configured. On the other hand, the support 20 may be composed of a plurality of members. For example, the fixed main body portion 22 and the connecting portion 23 are configured as one member, and 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.
　・支持具２０は、樹脂によって構成されてもよい。支持具２０を樹脂によって構成することによって、支持具２０の軽量化を図ることができる。 - 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.
