<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 anchorbolt 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."
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
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>
Thesupport 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.
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
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>

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.

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.

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, theanchor 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>

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 anchorbolt 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.
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
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.

The embodiment described above is an example of the form that the anchor
・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.
