本発明は、棒状体固定具に関する。 The present invention relates to a rod-shaped body fixing device.

吊ボルト等の棒状体（第一棒状体）を用いて天井スラブ等の構造体から吊設されるケーブルラック等の吊設機器の吊下支持を補強するため、構造体と第一棒状体とに亘ってブレースボルト等の別の棒状体（第二棒状体）を斜めに掛け渡して固定する場合がある。この場合、構造体に対して斜めに延びる第二棒状体を構造体に固定するのに、棒状体固定具が用いられる。 In order to reinforce the suspension support of a suspended device such as a cable rack that is suspended from a structure such as a ceiling slab using a rod-shaped body (first rod-shaped body) such as a hanging bolt, another rod-shaped body (second rod-shaped body) such as a brace bolt may be fixed diagonally across the structure and the first rod-shaped body. In this case, a rod-shaped body fixing device is used to fix the second rod-shaped body, which extends diagonally relative to the structure, to the structure.

このような棒状体固定具の一例が、例えば特開２０１４－５２０１４号公報（特許文献１）に開示されている。本願の図１２に転載しつつ一部拡大して示すように、特許文献１の棒状体固定具１００は、帯板状部材で構成されており、構造体に取り付けられる取付片１０１と、第二棒状体Ｑに固定される固定片１０２と、取付片１０１と固定片１０２とを接続する接続片１０３とを有している。棒状体固定具１００は、取付片１０１に形成された挿通孔に挿通される取付部材１１０で構造体に取り付けられ、第二棒状体Ｑは、固定片１０２に形成された挿通孔に挿通された状態で、一対のナット１２１，１２２を用いて両側から締め付けられて固定片１０２に固定されている。 One example of such a rod-shaped body fixing device is disclosed in, for example, Japanese Patent Application Laid-Open Publication No. 2014-52014 (Patent Document 1). As shown in FIG. 12 of the present application, which is partially enlarged, the rod-shaped body fixing device 100 of Patent Document 1 is composed of a strip-shaped member and has an attachment piece 101 that is attached to the structure, a fixed piece 102 that is fixed to the second rod-shaped body Q, and a connection piece 103 that connects the attachment piece 101 and the fixed piece 102. The rod-shaped body fixing device 100 is attached to the structure by an attachment member 110 that is inserted into an insertion hole formed in the attachment piece 101, and the second rod-shaped body Q is inserted into an insertion hole formed in the fixed piece 102 and fixed to the fixed piece 102 by tightening it from both sides using a pair of nuts 121, 122.

特許文献１の棒状体固定具１００では、当該棒状体固定具１００を構成する帯板状部材の屈曲角度（接続片１０３の配設角度）に応じて第二棒状体Ｑの配設角度が決まり、施工現場の状況に応じて第二棒状体Ｑの配設角度を調整することが難しかった。また、固定片１０２に第二棒状体Ｑを固定するには、まず、第１のナット１２１を第二棒状体Ｑに予め螺合させておき、その状態で第二棒状体Ｑの先端を固定片１０２の挿通孔に挿通させる。その後、第２のナット１２２を第二棒状体Ｑの先端に螺合させて固定片１０２の近傍まで移動させ、最後に２つのナット１２１，１２２を固定片１０２の両側から締め付けて固定する。しかも、第２のナット１２２の操作を、固定片１０２と構造体との間の狭い空間で行わなければならない。このため、これら一連の操作を行うのに、多くの労力を要していた。 In the rod-shaped body fixing device 100 of Patent Document 1, the arrangement angle of the second rod-shaped body Q is determined according to the bending angle (arrangement angle of the connection piece 103) of the strip-shaped member constituting the rod-shaped body fixing device 100, and it was difficult to adjust the arrangement angle of the second rod-shaped body Q according to the situation at the construction site. In addition, to fix the second rod-shaped body Q to the fixed piece 102, first, the first nut 121 is screwed onto the second rod-shaped body Q in advance, and in this state, the tip of the second rod-shaped body Q is inserted into the insertion hole of the fixed piece 102. After that, the second nut 122 is screwed onto the tip of the second rod-shaped body Q and moved to the vicinity of the fixed piece 102, and finally the two nuts 121 and 122 are tightened from both sides of the fixed piece 102 to fix it. Moreover, the operation of the second nut 122 must be performed in a narrow space between the fixed piece 102 and the structure. For this reason, it took a lot of effort to perform this series of operations.

特開２０１４－５２０１４号公報JP 2014-52014 A

構造体に対して棒状体を所望の配設角度で容易に固定することができる棒状体固定具の実現が望まれる。 It is desirable to develop a rod-shaped body fixing device that can easily fix a rod-shaped body to a structure at a desired angle.

本発明に係る棒状体固定具は、
構造体に対して斜めに延びる棒状体を前記構造体に固定する棒状体固定具であって、
前記構造体の被取付面に沿う取付部と、前記棒状体の延在方向に沿う連結部と、を有するベース部材と、
締結部材を用いて、前記連結部に回動自在に連結され、かつ、前記棒状体を挟み込んだ状態で保持する挟着部材と、を備える。 The rod-shaped body fixing device according to the present invention comprises:
A rod-shaped body fixing device that fixes a rod-shaped body extending obliquely to a structure to the structure,
A base member having an attachment portion that is aligned with the attachment surface of the structure and a connecting portion that is aligned with the extending direction of the rod-shaped body;
The rod-shaped body is provided with a clamping member that is rotatably connected to the connecting portion by using a fastening member and that holds the rod-shaped body in a clamped state.

この構成によれば、棒状体を挟み込んだ状態で保持する挟着部材が締結部材を用いて連結部に回動自在に連結されるので、挟着部材の位相に応じて、棒状体を所望の角度に配設することができる。また、挟着部材を連結部に固定するには、連結部に対して直交する方向から締結部材を締結すれば良く、比較的余裕のあるスペースで例えば電動工具を用いて固定操作を行うことも可能である。従って、構造体に対して棒状体を所望の配設角度で容易に固定することができる。 According to this configuration, the clamping member that holds the rod-shaped body in a clamped state is rotatably connected to the connecting part using the fastening member, so that the rod-shaped body can be arranged at a desired angle according to the phase of the clamping member. Furthermore, to fix the clamping member to the connecting part, it is sufficient to fasten the fastening member from a direction perpendicular to the connecting part, and it is also possible to perform the fixing operation in a relatively spacious space, for example, using an electric tool. Therefore, the rod-shaped body can be easily fixed to the structure at a desired arrangement angle.

以下、本発明の好適な態様について説明する。但し、以下に記載する好適な態様例によって、本発明の範囲が限定される訳ではない。 The following describes preferred embodiments of the present invention. However, the scope of the present invention is not limited to the preferred embodiments described below.

一態様として、
前記挟着部材が、前記連結部における前記取付部側の面に連結されていることが好ましい。 In one embodiment,
It is preferable that the clamping member is connected to a surface of the connecting portion on the side of the mounting portion.

この構成によれば、例えば挟着部材が連結部における取付部側とは反対側の面に連結されるような構成に比べて、棒状体固定具が、棒状体の延長線上に近い位置で構造体に取り付けられることになる。よって、構造体に対して棒状体を強固に固定することができる。 With this configuration, the rod-shaped body fixing device is attached to the structure at a position closer to the extension line of the rod-shaped body than, for example, a configuration in which the clamping member is connected to the surface of the connecting part opposite the mounting part side. Therefore, the rod-shaped body can be firmly fixed to the structure.

一態様として、
前記挟着部材は、前記連結部との間に前記棒状体を保持することが好ましい。 In one embodiment,
It is preferable that the clamping member holds the rod-shaped body between itself and the connecting portion.

この構成によれば、例えば挟着部材が単独で棒状体を挟み込んだ状態で保持しつつ連結部に連結されるような構成に比べて、部品点数を減らして構造の簡素化を図ることができるとともに低コスト化を図ることができる。また、緩んだ状態の締結部材を介して連結部と挟着部材とが仮組みされた状態で、それらをまとめて取り扱いながら作業を行うことができる。よって、作業性を高めることができる。 With this configuration, it is possible to reduce the number of parts, simplify the structure, and reduce costs, compared to a configuration in which the clamping member alone holds the rod-shaped body while clamping it and is connected to the connecting part. In addition, the connecting part and the clamping member are temporarily assembled via the loosened fastening member, and work can be performed while handling them together. This improves workability.

一態様として、
前記締結部材の緩締め状態で前記挟着部材を前記連結部側に向けて付勢するように、前記締結部材に弾性部材が装着されていることが好ましい。 In one embodiment,
It is preferable that an elastic member is attached to the fastening member so as to bias the clamping member toward the connecting portion when the fastening member is in a loosely fastened state.

この構成によれば、締結部材の緩締め状態で弾性部材の付勢力に抗して挟着部材を連結部から離間させ、その状態で連結部と挟着部材との間に棒状体をスライドさせて差し込むことができる。棒状体を差し込んだ後は、弾性部材の弾性復元力で挟着部材が連結部側に向けて付勢されるので、作業者の手を要さずとも、連結部と挟着部材との間に棒状体を仮止めすることができる。よって、作業性をさらに高めることができる。 With this configuration, when the fastening member is in a loosened state, the clamping member can be separated from the connecting portion against the biasing force of the elastic member, and in this state, the rod-shaped body can be slid and inserted between the connecting portion and the clamping member. After the rod-shaped body is inserted, the clamping member is biased toward the connecting portion by the elastic restoring force of the elastic member, so that the rod-shaped body can be temporarily fixed between the connecting portion and the clamping member without the need for the operator's hands. This further improves workability.

一態様として、
前記取付部は、前記被取付面に固定するための取付部材が挿通される挿通孔を有し、
前記被取付面に沿う方向において、前記挿通孔の形成位置と前記連結部における前記挟着部材の連結位置とが互いに離間していることが好ましい。 In one embodiment,
The mounting portion has an insertion hole through which a mounting member for fixing to the mounting surface is inserted,
It is preferable that a position where the insertion hole is formed and a position where the clamping member is connected to the connecting portion are separated from each other in a direction along the mounting surface.

この構成によれば、取付部材を用いてベース部材を構造体の被取付面に取り付ける際に、挟着部材と取付部材とが干渉するのを回避することができる。このため、ベース部材から挟着部材を取り外さずともベース部材を構造体の被取付面に取り付けることができる。
よって、作業性を高めることができる。 According to this configuration, when the base member is attached to the mounting surface of the structure using the mounting member, interference between the clamping member and the mounting member can be avoided, so that the base member can be attached to the mounting surface of the structure without removing the clamping member from the base member.
Therefore, the workability can be improved.

一態様として、
前記ベース部材が、前記棒状体を前記挟着部材における前記棒状体の固定部位へと案内するガイド部をさらに有することが好ましい。 In one embodiment,
It is preferable that the base member further includes a guide portion for guiding the rod-shaped body to a fixing portion of the clamping member for the rod-shaped body.

この構成によれば、ベース部材のガイド部の案内機能により、ベース部材における挟着部材の配設面側に棒状体を誘導することができ、棒状体を挟み込んだ状態で容易に保持することができる。 With this configuration, the guide function of the guide portion of the base member allows the rod-shaped body to be guided to the side of the base member where the clamping member is placed, making it easy to hold the rod-shaped body in a clamped state.

一態様として、
前記ベース部材が、前記挟着部材が当該挟着部材の前記固定部位が前記ガイド部の存在範囲を超えて回転するのを規制する回転規制部をさらに有することが好ましい。 In one embodiment,
It is preferable that the base member further includes a rotation restricting portion that restricts the clamping member from rotating beyond a range in which the fixed portion of the clamping member exists and beyond a range in which the guide portion exists.

この構成によれば、ガイド部が案内機能を適切に発揮する状態で、棒状体を挟み込んで容易に保持することができる。 With this configuration, the guide portion can easily clamp and hold the rod-shaped object while properly performing its guiding function.

一態様として、前記取付部と前記連結部とが直交していることが好ましい。 In one embodiment, it is preferable that the attachment portion and the connecting portion are perpendicular to each other.

この構成によれば、構造体の被取付面が水平に設置されるような構成において、本発明に係る棒状体固定具を好適に使用して、構造体に対して棒状体を所望の配設角度で容易に固定することができる。 With this configuration, in a structure in which the mounting surface of the structure is installed horizontally, the rod-shaped body fixing device of the present invention can be used favorably to easily fix the rod-shaped body to the structure at the desired angle.

一態様として、
前記連結部に、前記挟着部材の被取付面とは反対側に向かって突出する環状突起が形成されていることが好ましい。 In one embodiment,
It is preferable that the connecting portion is formed with an annular projection that projects toward the opposite side to the mounting surface of the clamping member.

この構成によれば、環状突起を備えることで連結部の強度を高めることができる。その環状突起は、挟着部材の被取付面とは反対側に向かって突出するので、連結部に挟着部材を回動自在に連結するにあたって邪魔になることもない。 With this configuration, the annular protrusion can increase the strength of the connecting portion. The annular protrusion protrudes toward the opposite side of the surface to which the clamping member is attached, so it does not get in the way of connecting the clamping member to the connecting portion so that it can rotate freely.

一態様として、
前記締結部材は、締結ボルトと、当該締結ボルトに螺合される締結ナットと、を含み、
前記環状突起が前記挟着部材の連結位置の周囲に形成されているとともに、前記締結部材の締結時における前記締結ナットの供回りを防止する供回り防止部が前記環状突起に形成されていることが好ましい。 In one embodiment,
The fastening member includes a fastening bolt and a fastening nut screwed onto the fastening bolt,
It is preferable that the annular protrusion is formed around the connecting position of the clamping member, and that a co-rotation prevention portion is formed on the annular protrusion to prevent co-rotation of the fastening nut when the fastening member is fastened.

この構成によれば、連結部の強度を高めるための環状突起を利用して、締結部材の締結時における締結ナットの供回りを防止することができる。よって、作業性を高めることができる。 With this configuration, the annular protrusion that increases the strength of the connection can be used to prevent the fastening nut from rotating when the fastening member is fastened. This improves workability.

本発明のさらなる特徴と利点は、図面を参照して記述する以下の例示的かつ非限定的な実施形態の説明によってより明確になるであろう。 Further features and advantages of the present invention will become more apparent from the following description of exemplary and non-limiting embodiments, which are given with reference to the drawings.

棒状体固定具の実施形態について、図面を参照して説明する。本実施形態の棒状体固定具１は、構造体９０に対して斜めに延びるブレースボルト７０を構造体９０に固定するための器具である。この棒状体固定具１は、構造体９０に固定されるベース部材１０と、締結部材３０を用いて、ベース部材１０に回動自在に連結され、かつ、ブレースボルト７０を挟み込んだ状態で保持する挟着部材２０とを備える。このような構成の棒状体固定具１を用いることで、構造体９０に対してブレースボルト７０を所望の配設角度で容易に固定することができる。 An embodiment of the rod-shaped body fixing tool will be described with reference to the drawings. The rod-shaped body fixing tool 1 of this embodiment is a tool for fixing a brace bolt 70 extending obliquely relative to the structure 90 to the structure 90. This rod-shaped body fixing tool 1 comprises a base member 10 that is fixed to the structure 90, and a clamping member 20 that is rotatably connected to the base member 10 using a fastening member 30 and holds the brace bolt 70 in a clamped state. By using the rod-shaped body fixing tool 1 configured in this way, the brace bolt 70 can be easily fixed to the structure 90 at a desired angle.

図１に、構造体９０に吊設機器６５を吊り下げ支持する支持構造を示す。本支持構造は、構造体９０から垂設された吊ボルト６０を吊設機器６５に固定してなる。なお、構造体９０は例えばコンクリート製の天井スラブや梁等であって良く、吊設機器６５は例えばケーブルラックや照明機器、空調機器の室内機等（これらの支持部材を含む）であって良い。 Figure 1 shows a support structure that supports suspended equipment 65 by suspending it from a structure 90. This support structure is formed by fixing suspension bolts 60 suspended from the structure 90 to the suspended equipment 65. The structure 90 may be, for example, a concrete ceiling slab or beam, and the suspended equipment 65 may be, for example, a cable rack, lighting equipment, or indoor units of air conditioning equipment (including the support members for these).

吊設機器６５を吊り下げ支持した吊ボルト６０と構造体９０とに亘って、吊ボルト６０とは別のブレースボルト７０が、斜めに掛け渡して固定されている。ブレースボルト７０は、一方の端部側で棒状体固定具１を用いて構造体９０に固定されており、他方の端部側で交差連結具８０を用いて吊ボルト６０に固定されている。本実施形態では、ブレースボルト７０が「棒状体」に相当する。 A brace bolt 70, separate from the hanging bolt 60, is fixed diagonally across the hanging bolt 60 that suspends and supports the hanging equipment 65 and the structure 90. One end of the brace bolt 70 is fixed to the structure 90 using a rod-shaped body fixing device 1, and the other end is fixed to the hanging bolt 60 using a cross connector 80. In this embodiment, the brace bolt 70 corresponds to the "rod-shaped body."

図２～図６に示すように、本実施形態の棒状体固定具１は、ベース部材１０と、挟着部材２０と、締結部材３０と、弾性部材４０とを備えている。締結部材３０により、挟着部材２０がベース部材１０に取り付けられている。締結部材３０には、弾性部材４０が装着されている。 As shown in Figures 2 to 6, the rod-shaped body fixing device 1 of this embodiment includes a base member 10, a clamping member 20, a fastening member 30, and an elastic member 40. The clamping member 20 is attached to the base member 10 by the fastening member 30. The elastic member 40 is attached to the fastening member 30.

ベース部材１０は、挟着部材２０を取り付けるための基材である。本実施形態のベース部材１０は、例えば金属製の板材で構成されている。ベース部材１０は、取付部１１と連結部１３とを有する。また、ベース部材１０は、ガイド部１５と回転規制部１６とをさらに有する。これらの取付部１１、連結部１３、ガイド部１５、及び回転規制部１６は、一体的に形成されている。 The base member 10 is a substrate for mounting the clamping member 20. In this embodiment, the base member 10 is made of, for example, a metal plate. The base member 10 has an attachment portion 11 and a connecting portion 13. The base member 10 further has a guide portion 15 and a rotation restricting portion 16. The attachment portion 11, the connecting portion 13, the guide portion 15, and the rotation restricting portion 16 are integrally formed.

取付部１１は、構造体９０の被取付面９０ａに沿う部位である。取付部１１は、構造体９０の被取付面９０ａに沿う平板状（平坦な板状）に形成されている。取付部１１は、被取付面９０ａに固定するための取付部材５０が挿通される挿通孔１２を有している。取付部材５０は、例えば被取付面９０ａから下方に突出する状態で構造体９０に埋め込まれたアンカーボルト５１と、それに螺合するナット５２とを含んでいる（図７を参照）。アンカーボルト５１が挿通孔１２を挿通する状態でナット５２を締結することで、被取付面９０ａと取付部１１とが全面的に密着する状態で、構造体９０にベース部材１０が固定される。 The mounting portion 11 is a portion that fits along the mounting surface 90a of the structure 90. The mounting portion 11 is formed in a flat plate shape (flat plate shape) that fits along the mounting surface 90a of the structure 90. The mounting portion 11 has an insertion hole 12 through which a mounting member 50 for fixing to the mounting surface 90a is inserted. The mounting member 50 includes, for example, an anchor bolt 51 embedded in the structure 90 in a state in which it protrudes downward from the mounting surface 90a, and a nut 52 that screws onto it (see FIG. 7). By fastening the nut 52 with the anchor bolt 51 inserted through the insertion hole 12, the base member 10 is fixed to the structure 90 with the mounting surface 90a and the mounting portion 11 in full contact with each other.

連結部１３は、取付部１１に対して交差する状態で配置されている。本実施形態では、連結部１３は、取付部１１に直交する状態で配置されている。また、連結部１３は、ブレースボルト７０の延在方向に沿う平板状（平坦な板状）に形成されている。連結部１３は、種々の配設角度に応じたブレースボルト７０の延在方向を全て包含する仮想平面に沿うように形成されている。連結部１３は、正面視で平行四辺形状をなす第一部位１３Ａと、正面視で半円状をなす第二部位１３Ｂとを有する。第一部位１３Ａは、取付部１１から連続して形成されており、第一部位１３Ａの下方に連続して第二部位１３Ｂが形成されている。連結部１３（中でも、特に第二部位１３Ｂ）は、挟着部材２０が固定される部位となる。 The connecting portion 13 is disposed in a state in which it intersects with the mounting portion 11. In this embodiment, the connecting portion 13 is disposed in a state in which it intersects with the mounting portion 11 at right angles. The connecting portion 13 is formed in a flat plate shape (flat plate shape) along the extension direction of the brace bolt 70. The connecting portion 13 is formed along a virtual plane that includes all of the extension directions of the brace bolt 70 according to various arrangement angles. The connecting portion 13 has a first portion 13A that is a parallelogram shape in a front view and a second portion 13B that is a semicircle shape in a front view. The first portion 13A is formed continuously from the mounting portion 11, and the second portion 13B is formed continuously below the first portion 13A. The connecting portion 13 (particularly the second portion 13B) is the portion to which the clamping member 20 is fixed.

連結部１３の中心部付近（本例では、第一部位１３Ａと第二部位１３Ｂとの境界部付近）には、締結部材３０を構成する締結ボルト３１の軸部が締結される被締結部１４が形成されている。本実施形態では、被締結部１４は、内面に雌ネジ部が形成されたバーリングタップ部で構成されている。 Near the center of the connecting portion 13 (in this example, near the boundary between the first portion 13A and the second portion 13B), a fastening portion 14 is formed to which the shank of the fastening bolt 31 constituting the fastening member 30 is fastened. In this embodiment, the fastening portion 14 is composed of a burring tap portion with a female thread formed on the inner surface.

本実施形態では、連結部１３における取付部１１側の面が、挟着部材２０が連結される被取付面となっている。言い換えれば、直角屈曲形状のベース部材１０の屈曲内面に、挟着部材２０の被取付面が設けられている。この場合、被締結部１４は、ベース部材１０の屈曲外面側（取付部１１とは反対側）に突出して設けられる。このような構成では、ベース部材１０の屈曲外面に挟着部材２０が連結されるような構成に比べて、棒状体固定具１が、ブレースボルト７０の延長線上に近い位置で構造体９０に取り付けられることになる。よって、構造体９０に対してブレースボルト７０を強固に固定することができる。 In this embodiment, the surface of the connecting portion 13 facing the mounting portion 11 is the mounting surface to which the clamping member 20 is connected. In other words, the mounting surface of the clamping member 20 is provided on the inner curved surface of the base member 10, which has a right-angled bent shape. In this case, the fastening portion 14 is provided protruding from the outer curved surface side of the base member 10 (the side opposite the mounting portion 11). In this configuration, the rod-shaped body fixing device 1 is attached to the structure 90 at a position closer to the extension line of the brace bolt 70 than in a configuration in which the clamping member 20 is connected to the outer curved surface of the base member 10. Therefore, the brace bolt 70 can be firmly fixed to the structure 90.

本実施形態では、上述したように平行四辺形状の第一部位１３Ａと半円状の第二部位１３Ｂとを有することで、連結部１３が斜めに延在するように形成されている。このため、被取付面９０ａに沿う方向において、取付部１１における挿通孔１２の形成位置と、連結部１３における挟着部材２０の連結位置（被締結部１４の形成位置）とが、互いに離間している。挿通孔１２の形成位置と挟着部材２０の連結位置とは、それらの中心間距離が例えば挟着部材２０の半幅以上（好ましくは挟着部材２０の幅以上）となるように互いに離間していると良い。こうすることで、構造体９０にベース部材１０を固定する際に、ナット５２を締付操作するための工具と挟着部材２０とが干渉せず、固定作業を容易に行うことができる。 In this embodiment, as described above, the first portion 13A has a parallelogram shape and the second portion 13B has a semicircular shape, so that the connecting portion 13 extends obliquely. Therefore, in the direction along the mounting surface 90a, the position where the insertion hole 12 is formed in the mounting portion 11 and the connecting position of the clamping member 20 (the position where the fastened portion 14 is formed) in the connecting portion 13 are separated from each other. The position where the insertion hole 12 is formed and the connecting position of the clamping member 20 are preferably separated from each other so that the center distance between them is, for example, half the width of the clamping member 20 or more (preferably the width of the clamping member 20 or more). In this way, when fixing the base member 10 to the structure 90, the tool for tightening the nut 52 does not interfere with the clamping member 20, and the fixing work can be easily performed.

ガイド部１５は、連結部１３の第二部位１３Ｂの周方向の一部の領域において径方向に突出するように形成されている。ガイド部１５は、締結部材３０の位置となる被締結部１４の位置を中心とする円弧帯状に形成されている。本実施形態では、ガイド部１５は、中心角がおよそ９０°となる円弧帯状に形成されている。ガイド部１５は、平板状の連結部１３に対して傾斜するように屈曲形成されている。ガイド部１５は、平板状の連結部１３に対して、取付部１１とは反対側に傾斜するように屈曲形成されている。連結部１３とガイド部１５との傾斜角度（なす角）は、例えば１２０°～１５０°であって良く、本実施形態では１３５°程度に設定されている。ガイド部１５は、ブレースボルト７０を、挟着部材２０におけるブレースボルト７０の固定部位である湾曲部２４へと案内する役割を果たす。 The guide portion 15 is formed so as to protrude in the radial direction in a part of the circumferential region of the second portion 13B of the connecting portion 13. The guide portion 15 is formed in an arc band shape centered on the position of the fastened portion 14, which is the position of the fastening member 30. In this embodiment, the guide portion 15 is formed in an arc band shape with a central angle of approximately 90°. The guide portion 15 is bent and formed so as to be inclined with respect to the flat connecting portion 13. The guide portion 15 is bent and formed so as to be inclined on the opposite side to the mounting portion 11 with respect to the flat connecting portion 13. The inclination angle (angle formed) between the connecting portion 13 and the guide portion 15 may be, for example, 120° to 150°, and is set to about 135° in this embodiment. The guide portion 15 serves to guide the brace bolt 70 to the curved portion 24, which is the fixing portion of the brace bolt 70 in the clamping member 20.

回転規制部１６は、連結部１３に直交する状態で配置された起立片で構成されている。回転規制部１６は、連結部１３の第二部位１３Ｂの周方向の一部の領域であって、円弧帯状のガイド部１５とは異なる位置に設けられている。回転規制部１６は、ガイド部１５に沿う周方向（被締結部１４の位置を中心とする回転方向）において、ガイド部１５に対して取付部１１とは反対側となる位置に設けられている。回転規制部１６は、挟着部材２０が、当該挟着部材２０の湾曲部２４がガイド部１５の存在範囲を超えて回転するのを規制する役割を果たす。 The rotation restricting portion 16 is composed of an upright piece arranged perpendicular to the connecting portion 13. The rotation restricting portion 16 is provided in a portion of the circumferential area of the second portion 13B of the connecting portion 13, at a position different from the arc-shaped guide portion 15. The rotation restricting portion 16 is provided at a position on the opposite side of the guide portion 15 to the attachment portion 11 in the circumferential direction along the guide portion 15 (the rotation direction centered on the position of the fastened portion 14). The rotation restricting portion 16 serves to restrict the clamping member 20 from rotating beyond the range in which the curved portion 24 of the clamping member 20 exists.

挟着部材２０は、締結部材３０を用いて、連結部１３に回動自在に連結され、かつ、ブレースボルト７０を挟み込んだ状態で保持する。挟着部材２０は、締結部材３０の不完全締結状態で連結部１３に回動自在に連結されるとともに、締結部材３０の完全締結状態でブレースボルト７０を挟み込んだ状態で保持する。本実施形態の挟着部材２０は、ベース部材１０の連結部１３と協働して、当該連結部１３との間にブレースボルト７０を保持する。挟着部材２０は、例えば金属製の板材で構成されている。挟着部材２０は、本体部２１と湾曲部２４とリブ部２６とを有する。これらの本体部２１、湾曲部２４、及びリブ部２６は、一体的に形成されている。 The clamping member 20 is rotatably connected to the connecting portion 13 using the fastening member 30, and holds the brace bolt 70 in a clamped state. The clamping member 20 is rotatably connected to the connecting portion 13 when the fastening member 30 is in an incompletely fastened state, and holds the brace bolt 70 in a clamped state when the fastening member 30 is in a completely fastened state. The clamping member 20 of this embodiment cooperates with the connecting portion 13 of the base member 10 to hold the brace bolt 70 between the connecting portion 13. The clamping member 20 is made of, for example, a metal plate material. The clamping member 20 has a main body portion 21, a curved portion 24, and a rib portion 26. The main body portion 21, the curved portion 24, and the rib portion 26 are integrally formed.

本体部２１は、ベース部材１０に重ね合わされて当該ベース部材１０への固定部となる部位である。本体部２１は、矩形状領域と半円状領域とが組み合わされてなるＤ字状に形成されている。本体部２１の中心部には、締結部材３０を構成する締結ボルト３１の軸部が挿通可能な挿通孔２２が形成されている。また、本体部２１には、挿通孔２２を取り囲むように環状突起２３が形成されている。環状突起２３は、ベース部材１０とは反対側に向かって突出するように形成されている。 The main body 21 is a portion that is overlaid on the base member 10 and serves as a fixed portion to the base member 10. The main body 21 is formed in a D-shape that combines a rectangular region and a semicircular region. In the center of the main body 21, an insertion hole 22 is formed through which the shaft of the fastening bolt 31 that constitutes the fastening member 30 can be inserted. In addition, the main body 21 is formed with an annular protrusion 23 that surrounds the insertion hole 22. The annular protrusion 23 is formed so as to protrude toward the opposite side to the base member 10.

湾曲部２４は、Ｄ字状の本体部２１における矩形状領域から、半円状領域とは反対側に延出している。本実施形態では、湾曲部２４は、側面視形状がおよそ１８０°の中心角を有する円弧状となる湾曲板部として形成されている。湾曲部２４は、吊ボルト６０の外面に概ね沿うように湾曲している。湾曲部２４は、吊ボルト６０を包囲する状態で当該吊ボルト６０を実際に固定する部位であり、「挟着部材における棒状体の固定部位」に相当する。 The curved portion 24 extends from the rectangular region of the D-shaped main body 21 to the side opposite the semicircular region. In this embodiment, the curved portion 24 is formed as a curved plate portion whose side view shape is an arc with a central angle of approximately 180°. The curved portion 24 is curved so as to generally follow the outer surface of the hanging bolt 60. The curved portion 24 is the portion that actually fixes the hanging bolt 60 in a state in which it surrounds the hanging bolt 60, and corresponds to the "fixing portion of the rod-shaped body in the clamping member."

湾曲部２４の内面には、ブレースボルト７０の外面のネジ部に係止される係止突起２５が突出形成されている。ブレースボルト７０に対して軸方向の複数箇所で係止可能なように、複数の係止突起２５が分散して設けられている。このような係止突起２５を有することで、棒状体固定具１に対するブレースボルト７０の位置ズレを抑制することができる。 A locking protrusion 25 is formed on the inner surface of the curved portion 24 to lock onto the threaded portion on the outer surface of the brace bolt 70. A plurality of locking protrusions 25 are provided in a distributed manner so that the brace bolt 70 can be locked at multiple points in the axial direction. By having such locking protrusions 25, it is possible to prevent the position of the brace bolt 70 from shifting relative to the rod-shaped body fixing device 1.

リブ部２６は、挟着部材２０の幅方向両側において、本体部２１の少なくとも一部と湾曲部２４の少なくとも一部とに亘って一体的に形成されている。本実施形態では、本体部２１の一部と湾曲部２４の全部とに亘って、リブ部２６が形成されている。リブ部２６は、本体部２１及び湾曲部２４の板面に対して交差（本例では直交）している。このようなリブ部２６を有することで、挟着部材２０の強度の向上が図られている。 The rib portions 26 are integrally formed over at least a portion of the main body portion 21 and at least a portion of the curved portion 24 on both sides of the width of the clamping member 20. In this embodiment, the rib portions 26 are formed over a portion of the main body portion 21 and the entire curved portion 24. The rib portions 26 intersect (orthogonal in this example) with the plate surfaces of the main body portion 21 and the curved portion 24. By having such rib portions 26, the strength of the clamping member 20 is improved.

リブ部２６における湾曲部２４の先端側の角部は、角の尖った先鋭状ではなく、側面視で丸みを帯びたＲ状に形成されている。このリブ部２６のＲ状の角部は、ブレースボルト７０を湾曲部２４（これは、挟着部材２０におけるブレースボルト７０の固定部位である）へと案内する機能を果たす。すなわち、リブ部２６のＲ状の角部により、ブレースボルト７０を湾曲部２４へと案内する、挟着部材２０のガイド部２６Ａが構成されている（図８を参照）。 The corner of the rib portion 26 at the tip side of the curved portion 24 is not sharp, but is rounded in a R shape when viewed from the side. This R-shaped corner of the rib portion 26 serves to guide the brace bolt 70 to the curved portion 24 (this is the fixing portion of the brace bolt 70 in the clamping member 20). In other words, the R-shaped corner of the rib portion 26 constitutes the guide portion 26A of the clamping member 20 that guides the brace bolt 70 to the curved portion 24 (see Figure 8).

締結部材３０は、締結ボルト３１で構成されている。締結部材３０を構成する締結ボルト３１は、ベース部材１０の被締結部１４（本実施形態ではバーリングタップ部）に螺合して、ベース部材１０と挟着部材２０とを連結する。締結部材３０（締結ボルト３１）は、軸部が挟着部材２０の挿通孔２２に挿通された状態で、ベース部材１０の被締結部１４に締結される。そして、締結部材３０と被締結部１４とが締結されたとき、ワッシャー３５を介して、締結部材３０の頭部とベース部材１０との間に、挟着部材２０が連結固定される。そして、ベース部材１０と挟着部材２０との間に、ブレースボルト７０が挟み込んだ状態で保持される。なお、ワッシャー３５は、挟着部材２０の環状突起２３よりも大径のものを用いる。 The fastening member 30 is composed of a fastening bolt 31. The fastening bolt 31 constituting the fastening member 30 is screwed into the fastened portion 14 (burring tap portion in this embodiment) of the base member 10 to connect the base member 10 and the clamping member 20. The fastening member 30 (fastening bolt 31) is fastened to the fastened portion 14 of the base member 10 with the shaft portion inserted into the insertion hole 22 of the clamping member 20. When the fastening member 30 and the fastened portion 14 are fastened, the clamping member 20 is connected and fixed between the head of the fastening member 30 and the base member 10 via the washer 35. The brace bolt 70 is held in a sandwiched state between the base member 10 and the clamping member 20. The washer 35 has a larger diameter than the annular protrusion 23 of the clamping member 20.

弾性部材４０は、締結部材３０に装着されている。弾性部材４０としては、コイルばねが用いられており、より具体的には、軸方向の位置に応じてコイル径が次第に変化する円錐コイルばねが用いられている。弾性部材４０は、挟着部材２０に対してベース部材１０とは反対側で、締結部材３０を構成する締結ボルト３１の軸部に装着されている。弾性部材４０は、挟着部材２０と締結部材３０を構成する締結ボルト３１の頭部との間に、当該頭部側にワッシャー３５を介する状態で、締結部材３０に装着されている。また、弾性部材４０は、定常状態（外力が作用していない状態）に比べて圧縮された状態で、締結部材３０に装着されている。 The elastic member 40 is attached to the fastening member 30. A coil spring is used as the elastic member 40, and more specifically, a conical coil spring whose coil diameter gradually changes depending on the axial position is used. The elastic member 40 is attached to the shaft of the fastening bolt 31 constituting the fastening member 30 on the opposite side of the clamping member 20 from the base member 10. The elastic member 40 is attached to the fastening member 30 between the clamping member 20 and the head of the fastening bolt 31 constituting the fastening member 30, with a washer 35 interposed on the head side. The elastic member 40 is also attached to the fastening member 30 in a compressed state compared to the steady state (a state in which no external force is acting).

締結部材３０に装着された圧縮状態の弾性部材４０は、締結部材３０の緩締め状態で、挟着部材２０をベース部材１０側（連結部１３側）に向けて付勢する。なお、「締結部材３０の緩締め状態」とは、締結部材３０の軸部が被締結部１４に螺合され、かつ、完全には締結固定されていない状態である。湾曲部２４にブレースボルト７０が収容された状態の挟着部材２０をベース部材１０に押圧付勢することで、ブレースボルト７０の一方の端部を仮止めすることができる。 The elastic member 40 in a compressed state attached to the fastening member 30 biases the clamping member 20 toward the base member 10 (the connecting portion 13) when the fastening member 30 is in a loosely fastened state. Note that the "loosely fastened state of the fastening member 30" refers to a state in which the shaft portion of the fastening member 30 is screwed into the fastened portion 14, but is not completely fastened and fixed. By pressing and biasing the clamping member 20, with the brace bolt 70 housed in the curved portion 24, against the base member 10, one end of the brace bolt 70 can be temporarily secured.

本実施形態の棒状体固定具１は、ベース部材１０、挟着部材２０、締結部材３０、及び弾性部材４０の全てが仮組みされた状態（仮組状態）で施工することができる。なお、棒状体固定具１の仮組状態は、ワッシャー３５及び弾性部材４０が装着された締結部材３０が、挟着部材２０を貫通してベース部材１０の被締結部１４に螺合しつつ緩締め状態となっている状態である。なお、棒状体固定具１の仮組状態では、締結部材３０の軸部を軸として、ベース部材１０に対して挟着部材２０が、回転規制部１６や取付部材５０と干渉しない範囲で、回動自在に連結される（図７を参照）。 The rod-shaped body fixing device 1 of this embodiment can be installed in a state where the base member 10, the clamping member 20, the fastening member 30, and the elastic member 40 are all provisionally assembled (provisionally assembled state). The provisionally assembled state of the rod-shaped body fixing device 1 is a state where the fastening member 30, to which the washer 35 and the elastic member 40 are attached, penetrates the clamping member 20 and is loosely fastened while being screwed into the fastened portion 14 of the base member 10. In the provisionally assembled state of the rod-shaped body fixing device 1, the clamping member 20 is connected to the base member 10 so as to be freely rotatable about the shaft portion of the fastening member 30 within a range that does not interfere with the rotation restriction portion 16 or the mounting member 50 (see FIG. 7).

棒状体固定具１を用いてブレースボルト７０を構造体９０に固定するには、以下のようにすれば良い。まず、棒状体固定具１の仮組状態で、当該棒状体固定具１を構造体９０の被取付面９０ａに取り付ける。上述したように、構造体９０に埋め込まれたアンカーボルト５１を取付部１１の挿通孔１２に挿通させ、その状態でナット５２を締結することで、ベース部材１０を構造体９０に固定する。 The brace bolt 70 can be fixed to the structure 90 using the rod-shaped body fixing device 1 as follows. First, in a provisionally assembled state, the rod-shaped body fixing device 1 is attached to the mounting surface 90a of the structure 90. As described above, the anchor bolt 51 embedded in the structure 90 is inserted into the insertion hole 12 of the mounting portion 11, and in this state, the nut 52 is tightened to fix the base member 10 to the structure 90.

次に、ブレースボルト７０の配設角度に応じて挟着部材２０のラフな角度調整を行ってから、棒状体固定具１にブレースボルト７０を取り付ける。このとき、図８に示すように、ベース部材１０のガイド部１５と挟着部材２０のガイド部２６Ａとの間に形成される側面視Ｖ字状の受け部に、ブレースボルト７０を当該ブレースボルト７０の径方向にあてがう。そのままブレースボルト７０を径方向に押し込むと、ブレースボルト７０が、２つのガイド部１５，２６Ａによって案内されて、ベース部材１０と挟着部材２０との間に進入し始める。そして、弾性部材４０の弾性付勢力に抗しながら、ベース部材１０に対して挟着部材２０がブレースボルト７０により押し広げられる。 Next, the angle of the clamping member 20 is roughly adjusted according to the angle at which the brace bolt 70 is disposed, and then the brace bolt 70 is attached to the rod-shaped body fixing device 1. At this time, as shown in FIG. 8, the brace bolt 70 is placed in the radial direction of the brace bolt 70 against a V-shaped receiving portion in a side view formed between the guide portion 15 of the base member 10 and the guide portion 26A of the clamping member 20. When the brace bolt 70 is pushed in the radial direction, the brace bolt 70 is guided by the two guide portions 15, 26A and begins to enter between the base member 10 and the clamping member 20. Then, the brace bolt 70 spreads the clamping member 20 against the base member 10 against the elastic force of the elastic member 40.

さらにブレースボルト７０を押し込むと、自ずと挟着部材２０の湾曲部２４がブレースボルト７０を包囲する状態となり、この状態で、弾性部材４０の弾性復元力により、ベース部材１０と挟着部材２０との間にブレースボルト７０が仮止めされる。このようにして、ブレースボルト７０を容易に仮止めすることができる。また、ブレースボルト７０を仮止めしつつ、当該ブレースボルト７０の配設角度に応じた挟着部材２０の最終の角度調整を容易に行うことができる。このように、本実施形態の棒状体固定具１を用いることで、施工現場毎の状況に応じたブレースボルト７０の様々な配設角度に、容易に対応することができる。 When the brace bolt 70 is further pushed in, the curved portion 24 of the clamping member 20 naturally surrounds the brace bolt 70, and in this state, the brace bolt 70 is temporarily fixed between the base member 10 and the clamping member 20 by the elastic restoring force of the elastic member 40. In this way, the brace bolt 70 can be easily temporarily fixed. Also, while the brace bolt 70 is temporarily fixed, the final angle adjustment of the clamping member 20 according to the installation angle of the brace bolt 70 can be easily performed. In this way, by using the rod-shaped body fixing device 1 of this embodiment, it is possible to easily accommodate various installation angles of the brace bolt 70 according to the conditions of each construction site.

その後、作業者は、両手を自由に使える状態で、締結部材３０の締結操作を行うことができる。また、連結部１３はブレースボルト７０の延在方向に沿う平板状に形成され、それに応じて締結部材３０はブレースボルト７０の延在方向に直交する方向に締結されるので、比較的余裕のあるスペースで締結部材３０の締結操作を行うことができる。このため、例えば電動工具を用いて締結部材３０の締結操作を行うことも可能であり、構造体９０へのブレースボルト７０の固定作業を容易に行うことができる。 The worker can then perform the fastening operation of the fastening member 30 with both hands free to use. In addition, the connecting portion 13 is formed in a flat plate shape along the extension direction of the brace bolt 70, and the fastening member 30 is accordingly fastened in a direction perpendicular to the extension direction of the brace bolt 70, so that the fastening operation of the fastening member 30 can be performed in a relatively ample space. For this reason, the fastening operation of the fastening member 30 can be performed using, for example, an electric tool, and the work of fixing the brace bolt 70 to the structure 90 can be easily performed.

締結部材３０を締め増して完全に締結すると、図９に示すように、締結部材３０の頭部と被締結部１４が設けられたベース部材１０の連結部１３との間に、ワッシャー３５を介して挟着部材２０が緊締された状態となる。この状態で、ベース部材１０と挟着部材２０とで、ブレースボルト７０を安定的に挟着固定することができる。 When the fastening member 30 is further tightened and completely fastened, as shown in FIG. 9, the clamping member 20 is tightened between the head of the fastening member 30 and the connecting portion 13 of the base member 10 on which the fastened portion 14 is provided, via the washer 35. In this state, the brace bolt 70 can be stably clamped and fixed between the base member 10 and the clamping member 20.

このとき、ワッシャー３５は挟着部材２０の環状突起２３よりも大径に形成されているので、ワッシャー３５が環状突起２３に当接支持された状態で、それらの間に、締結部材３０の軸部を取り巻く環状空間Ａが形成される。この環状空間Ａは、挟着部材２０の環状突起２３の内側に形成され、本体部２１から環状突起２３の突出高さ相当分の厚みを有する扁平空間である。 At this time, the washer 35 is formed with a larger diameter than the annular protrusion 23 of the clamping member 20, so that when the washer 35 is in contact with and supported by the annular protrusion 23, an annular space A is formed between them, surrounding the shaft of the fastening member 30. This annular space A is formed inside the annular protrusion 23 of the clamping member 20, and is a flat space with a thickness equivalent to the protruding height of the annular protrusion 23 from the main body 21.

この環状空間Ａに、高圧縮時に渦巻状の扁平形状となる円錐コイルばねからなる弾性部材４０が収容される。環状空間Ａは、弾性部材収容空間として機能する。このように、締結部材３０の締結後、挟着部材２０の環状突起２３の内側空間に弾性部材４０を収容することで、締結部材３０の締結後における弾性部材４０の影響を排除して、ブレースボルト７０を安定的に固定することができる。 The annular space A accommodates an elastic member 40 made of a conical coil spring that assumes a flat spiral shape when highly compressed. The annular space A functions as an elastic member accommodation space. In this way, by accommodating the elastic member 40 in the inner space of the annular protrusion 23 of the clamping member 20 after the fastening member 30 is fastened, the influence of the elastic member 40 after the fastening member 30 is fastened can be eliminated, and the brace bolt 70 can be stably fixed.

以上説明したように、本実施形態の棒状体固定具１によれば、挟着部材２０がブレースボルト７０を挟み込んだ状態で保持するので、構造体９０へのブレースボルト７０の固定に係る施工性を向上させることができる。図１１に示す従来仕様の棒状体固定具１００とは異なり、固定片１０２の両側での２つのナット１２１，１２２の締付操作が不要となるので、施工性を大幅に向上させることができる。また、締結部材３０の緩締め状態で挟着部材２０の角度調整を行うことができるので、施工現場毎の状況に応じたブレースボルト７０の様々な配設角度に、容易に対応することができる。 As described above, according to the rod-shaped body fixing device 1 of this embodiment, the clamping member 20 holds the brace bolt 70 in a clamped state, thereby improving the workability of fixing the brace bolt 70 to the structure 90. Unlike the rod-shaped body fixing device 100 of the conventional specification shown in FIG. 11, the tightening operation of the two nuts 121, 122 on both sides of the fixing piece 102 is not required, so the workability can be significantly improved. In addition, the angle of the clamping member 20 can be adjusted with the fastening member 30 in a loosened state, so it is possible to easily accommodate various installation angles of the brace bolt 70 according to the conditions of each construction site.

また、緩締め状態の締結部材３０に圧縮状態の弾性部材４０が装着されているので、弾性部材４０の付勢力でブレースボルト７０を仮止めすることができる。そしてその状態で、作業者は両手で締結部材３０の締結操作を行うことができる。しかも、連結部１３の横に広がる比較的余裕のあるスペースで、例えば電動工具を用いて締結部材３０の締結操作を容易に行うことができる。よって、この点からも、構造体９０へのブレースボルト７０の固定作業に係る施工性を大幅に向上させることができる。 In addition, because the elastic member 40 in a compressed state is attached to the fastening member 30 in a loosely tightened state, the brace bolt 70 can be temporarily fixed by the biasing force of the elastic member 40. In this state, the worker can perform the fastening operation of the fastening member 30 with both hands. Moreover, in the relatively ample space that spreads out to the side of the connecting portion 13, the fastening operation of the fastening member 30 can be easily performed using, for example, an electric tool. Therefore, from this point of view, the workability of fixing the brace bolt 70 to the structure 90 can be significantly improved.

(1) In the above embodiment, a configuration has been described in which the clamping member 20 is connected to the surface of the connecting portion 13 on the mounting portion 11 side (the curved inner surface of the base member 10 having a right-angle bent shape). However, the present invention is not limited to such a configuration, and the clamping member 20 may be connected to the surface of the connecting portion 13 on the opposite side to the mounting portion 11 (the curved outer surface of the base member 10 having a right-angle bent shape).

（２）上記の実施形態では、取付部１１と連結部１３とが直交している構成を例として説明した。しかし、そのような構成に限定されることなく、取付部１１と連結部１３とが鋭角又は鈍角をなすように交差して配置されても良い。このような構成では、構造体９０の被取付面９０ａが水平ではなく傾斜して配置されるような構成においても、ベース部材１０側の交差角度を調整することで、連結部１３を鉛直姿勢で配置することができる。 (2) In the above embodiment, a configuration in which the mounting portion 11 and the connecting portion 13 are perpendicular to each other has been described as an example. However, the present invention is not limited to such a configuration, and the mounting portion 11 and the connecting portion 13 may be arranged to intersect at an acute or obtuse angle. In such a configuration, even if the mounting surface 90a of the structure 90 is arranged at an angle rather than horizontally, the connecting portion 13 can be arranged in a vertical position by adjusting the intersection angle on the base member 10 side.

（３）上記の実施形態では、被取付面９０ａに沿う方向において、取付部１１における挿通孔１２の形成位置と連結部１３における挟着部材２０の連結位置とが互いに離間している構成を例として説明した。しかし、そのような構成に限定されることなく、被取付面９０ａに沿う方向において、挿通孔１２の形成位置と連結部１３における挟着部材２０の連結位置とが同じであっても良い。 (3) In the above embodiment, a configuration has been described in which the position at which the insertion hole 12 is formed in the mounting portion 11 and the position at which the clamping member 20 is connected in the connecting portion 13 are spaced apart in the direction along the mounting surface 90a. However, the present invention is not limited to such a configuration, and the position at which the insertion hole 12 is formed and the position at which the clamping member 20 is connected in the connecting portion 13 may be the same in the direction along the mounting surface 90a.

（４）上記の実施形態では、被締結部１４がバーリングタップ部で構成されている例について説明した。しかし、そのような構成に限定されることなく、被締結部１４が、例えばベース部材１０における挟着部材２０とは反対側の面に固定された固定ナットであっても良い。この場合、ベース部材１０における被締結部１４（固定ナット）の位置には、締結部材３０の軸部が挿通される挿通孔が形成されると良い。 (4) In the above embodiment, an example was described in which the fastened portion 14 was configured as a burring tap portion. However, without being limited to such a configuration, the fastened portion 14 may be, for example, a fixed nut fixed to the surface of the base member 10 opposite the clamping member 20. In this case, it is preferable that an insertion hole through which the shaft portion of the fastening member 30 is inserted is formed at the position of the fastened portion 14 (fixed nut) on the base member 10.

（５）上記の実施形態では、ガイド部１５が、被締結部１４の位置を中心とする円弧帯状に形成されている構成を例として説明した。しかし、そのような構成に限定されることなく、ガイド部１５は、異なる形状の板体で構成されても良いし、複数の線状体等で構成されても良い。すなわち、少なくとも挟着部材２０におけるブレースボルト７０の固定部位である湾曲部２４へとブレースボルト７０を案内できるのであれば、ガイド部１５の具体的形状は任意に設定されて良い。或いは、ベース部材１０には、必ずしもガイド部１５が設けられなくても良い。 (5) In the above embodiment, the guide portion 15 is formed in an arc-shaped band centered on the position of the fastened portion 14. However, the present invention is not limited to such a configuration, and the guide portion 15 may be formed of a plate body of a different shape, or may be formed of multiple linear bodies, etc. In other words, the specific shape of the guide portion 15 may be set arbitrarily as long as it can guide the brace bolt 70 at least to the curved portion 24, which is the fixing portion of the brace bolt 70 in the clamping member 20. Alternatively, the guide portion 15 does not necessarily have to be provided on the base member 10.

（６）上記の実施形態では、回転規制部１６が、連結部１３に直交する状態で配置された起立片で構成されている例について説明した。しかし、そのような構成に限定されることなく、回転規制部１６が、例えば挟着部材２０側に向かって突出する突出部等で構成されても良い。すなわち、少なくとも挟着部材２０がその湾曲部２４がガイド部１５の存在範囲を超えて回転するのを規制できるのであれば、回転規制部１６の具体的形状は任意に設定されて良い。或いは、ベース部材１０には、必ずしも回転規制部１６が設けられなくても良い。 (6) In the above embodiment, an example was described in which the rotation regulating portion 16 is configured as an upright piece arranged perpendicular to the connecting portion 13. However, the present invention is not limited to such a configuration, and the rotation regulating portion 16 may be configured as, for example, a protrusion that protrudes toward the clamping member 20. In other words, the specific shape of the rotation regulating portion 16 may be set arbitrarily as long as it can at least regulate the curved portion 24 of the clamping member 20 from rotating beyond the range in which the guide portion 15 is present. Alternatively, the rotation regulating portion 16 does not necessarily have to be provided on the base member 10.

（７）上記の実施形態では、連結部１３が平坦な板状に形成されている構成を例として説明した。しかし、そのような構成に限定されることなく、連結部１３が非平坦に形成されても良い。例えば図１０に示すように、連結部１３に、挟着部材２０の被取付面とは反対側（ベース部材１０の屈曲外面側）に向かって突出する環状突起１８が形成されていても良い。このような環状突起１８を備えることで、連結部１３の強度を高めることができる。なお、図示の例では、ベース部材１０には被締結部１４は設けられておらず、被締結部１４に代えて、締結部材３０が締結ボルト３１に螺合される締結ナット３３を含んでいる。環状突起１８の内周側には締結ナット３３の外形形状に対応した六角形形状の凹部が形成されており、この凹部には、締結部材３０の緩締め状態で、弾性部材４０の付勢力によって締結ナット３３が係合する。この凹部は、締結部材３０の締結時における締結ナット３３の供回りを防止する供回り防止部１９として機能する。 (7) In the above embodiment, the connecting portion 13 is formed in a flat plate shape as an example. However, the present invention is not limited to such a configuration, and the connecting portion 13 may be formed non-flat. For example, as shown in FIG. 10, the connecting portion 13 may be formed with an annular protrusion 18 that protrudes toward the opposite side of the mounting surface of the clamping member 20 (the bent outer surface side of the base member 10). By providing such an annular protrusion 18, the strength of the connecting portion 13 can be increased. In the illustrated example, the base member 10 does not have a fastening portion 14, and instead of the fastening portion 14, the fastening member 30 includes a fastening nut 33 that is screwed onto the fastening bolt 31. A hexagonal recess corresponding to the outer shape of the fastening nut 33 is formed on the inner periphery of the annular protrusion 18, and the fastening nut 33 engages with this recess due to the biasing force of the elastic member 40 when the fastening member 30 is in a loosened state. This recess functions as a co-rotation prevention portion 19 that prevents the fastening nut 33 from co-rotating when the fastening member 30 is fastened.

（８）上記の実施形態において説明したベース部材１０や挟着部材２０の具体的構成は、あくまで例示であってそのような構成に限定されない。少なくともそれぞれの機能を発揮し得る限り、具体的形状は任意に設定することができる。例えば図１１に示すように、ベース部材１０は、一定幅のＬ字状の板状部材で構成されても良い。また、同図に示すように、挟着部材２０は、上面部を構成する本体部２１とその外縁から垂下する垂下壁部２７とを有するトレイ状（下面側が開口した箱状）に形成されても良い。この場合、ブレースボルト７０の外面に沿うように垂下壁部２７に形成された一対の切欠部２８で、ブレースボルト７０の固定部位が構成されても良い。もちろん、ベース部材１０及び挟着部材２０として、その他の形状を採用することも可能である。 (8) The specific configurations of the base member 10 and the clamping member 20 described in the above embodiment are merely examples and are not limited to such configurations. As long as they can at least perform their respective functions, the specific shapes can be set arbitrarily. For example, as shown in FIG. 11, the base member 10 may be configured as an L-shaped plate member of a certain width. Also, as shown in the same figure, the clamping member 20 may be formed in a tray shape (a box shape with an open bottom side) having a main body 21 that forms the upper surface and a hanging wall portion 27 that hangs down from the outer edge of the main body 21. In this case, the fixing portion of the brace bolt 70 may be configured by a pair of notches 28 formed in the hanging wall portion 27 so as to follow the outer surface of the brace bolt 70. Of course, other shapes can be adopted for the base member 10 and the clamping member 20.

（９）上記の実施形態では、挟着部材２０が、ベース部材１０の連結部１３との間にブレースボルト７０を挟み込んだ状態で保持する構成を例として説明した。しかし、そのような構成に限定されることなく、例えば挟着部材２０が、単独でブレースボルト７０を挟み込んだ状態で当該ブレースボルト７０を保持しつつ、ベース部材１０に連結されても良い。この場合、挟着部材２０は、単一部材（例えばループ部を有する板状部材など）で構成されても良いし、二部材（例えば平板状部材と包囲部を有する板状部材との組など）で構成されても良い。 (9) In the above embodiment, an example has been described in which the clamping member 20 holds the brace bolt 70 in a clamped state between itself and the connecting portion 13 of the base member 10. However, the present invention is not limited to such a configuration, and for example, the clamping member 20 may be connected to the base member 10 while holding the brace bolt 70 in a clamped state by itself. In this case, the clamping member 20 may be composed of a single member (such as a plate-shaped member having a loop portion) or two members (such as a combination of a flat plate-shaped member and a plate-shaped member having an enclosing portion).

（１０）上記の実施形態では、ベース部材１０と挟着部材２０との間の隙間に、ブレースボルト７０を径方向にスライドさせて横から差し込むことを主に想定して、施工手順について説明した。しかし、そのような構成に限定されることなく、ベース部材１０と挟着部材２０との間の隙間に、ブレースボルト７０を軸方向に（縦に）差し込んで挿通させても良い。 (10) In the above embodiment, the construction procedure was described assuming that the brace bolt 70 is slid radially and inserted laterally into the gap between the base member 10 and the clamping member 20. However, the present invention is not limited to such a configuration, and the brace bolt 70 may be inserted axially (vertically) into the gap between the base member 10 and the clamping member 20.

（１１）上記の実施形態では、締結部材３０に弾性部材４０が装着されている構成を例として説明した。しかし、そのような構成に限定されることなく、弾性部材４０は必ずしも締結部材３０に装着されていなくても良い。この場合、ブレースボルト７０の仮保持機能は失われるが、施工現場毎の状況に応じたブレースボルト７０の様々な配設角度への対応は可能であるし、構造体９０へのブレースボルト７０の固定に係る施工性を大幅に向上させることもできる。 (11) In the above embodiment, an example was described in which the elastic member 40 is attached to the fastening member 30. However, the present invention is not limited to such a configuration, and the elastic member 40 does not necessarily have to be attached to the fastening member 30. In this case, the temporary holding function of the brace bolt 70 is lost, but it is possible to accommodate various installation angles of the brace bolt 70 according to the conditions of each construction site, and it is also possible to significantly improve the ease of installation related to fixing the brace bolt 70 to the structure 90.

（１２）上述した各実施形態（上記の実施形態及びその他の実施形態を含む；以下同様）で開示される構成は、矛盾が生じない限り、他の実施形態で開示される構成と組み合わせて適用することも可能である。その他の構成に関しても、本明細書において開示された実施形態は全ての点で例示であって、本開示の趣旨を逸脱しない範囲内で適宜改変することが可能である。 (12) The configurations disclosed in each of the above-described embodiments (including the above-described embodiments and other embodiments; the same applies below) can also be applied in combination with configurations disclosed in other embodiments, as long as no contradiction arises. As for other configurations, the embodiments disclosed in this specification are illustrative in all respects and can be modified as appropriate within the scope of the present disclosure.
