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

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 hanging equipment such as cable racks that are suspended from structures such as ceiling slabs using rods such as suspension bolts (first rods), the structure and the first rods In some cases, another rod-like body (second rod-like body) such as a brace bolt is obliquely stretched over and fixed. In this case, a rod fixture is used to fix the second rod extending obliquely 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。 An example of such a rod-shaped body fixture is disclosed in Japanese Patent Laying-Open No. 2014-52014 (Patent Document 1), for example. As shown in FIG. 12 of the present application and partially enlarged, the rod-shaped body fixture 100 of Patent Document 1 is composed of a band plate-shaped member, and includes an attachment piece 101 attached to the structure and a second It has a fixed piece 102 fixed to the rod Q and a connecting piece 103 connecting the mounting piece 101 and the fixed piece 102 . The rod-shaped body fixture 100 is attached to the structure with a mounting member 110 that is inserted through an insertion hole formed in the mounting piece 101, and the second rod-shaped body Q is inserted through an insertion hole formed in the fixing piece 102. In this state, a pair of nuts 121 and 122 are used to tighten from both sides and fixed to the fixed piece 102 .

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 fixture 100 of Patent Document 1, the arrangement angle of the second rod-shaped body Q is determined according to the bending angle (the arrangement angle of the connection piece 103) of the strip-shaped member that constitutes the rod-shaped body fixture 100. , it was difficult to adjust the arrangement angle of the second rod Q according to the situation of the construction site. In addition, in order to fix the second rod Q to the fixing piece 102, first, the first nut 121 is screwed onto the second rod Q in advance, and the tip of the second rod Q is fixed in that state. It is made to pass through the insertion hole of the piece 102 . After that, the second nut 122 is screwed onto the tip of the second rod 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 and fixed. Moreover, the second nut 122 must be operated in a narrow space between the fixed piece 102 and the structure. Therefore, a lot of labor was required to perform these series of operations.

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 on the side of the mounting portion 11 serves as a mounting surface to which the sandwiching member 20 is connected. In other words, the mounting surface of the sandwiching member 20 is provided on the bent inner surface of the base member 10 having a right-angled bent shape. In this case, the fastened portion 14 is provided so as to protrude on the bent outer surface side of the base member 10 (the side opposite to the mounting portion 11). In such a configuration, the bar fixture 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 sandwiching member 20 is connected to the bent outer surface of the base member 10. will be 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 the present embodiment, the parallelogram-shaped first portion 13A and the semicircular second portion 13B are provided as described above, so that the connecting portion 13 is formed to extend obliquely. Therefore, in the direction along the mounting surface 90a, the formation position of the insertion hole 12 in the mounting portion 11 and the connection position of the clamping member 20 in the connection portion 13 (formation position of the fastened portion 14) are separated from each other. ing. The position where the insertion hole 12 is formed and the position where the clamping member 20 is connected are separated from each other so that the center-to-center distance therebetween is, for example, at least half the width of the clamping member 20 (preferably at least the width of the clamping member 20). It's good to be By doing so, when fixing the base member 10 to the structure 90, the clamping member 20 and the tool for tightening the nut 52 do not interfere with each other, 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 radially protrude from a portion of the second portion 13</b>B of the connecting portion 13 in the circumferential direction. The guide portion 15 is formed in an arc belt 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 arcuate belt shape with a central angle of approximately 90°. The guide portion 15 is bent so as to be inclined with respect to the flat connecting portion 13 . The guide portion 15 is formed so as to be bent in a direction opposite 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 where the brace bolt 70 is fixed 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 part of the circumferential direction of the second portion 13</b>B of the connecting portion 13 and at a position different from the arc-shaped guide portion 15 . The rotation restricting portion 16 is provided at a position opposite to the mounting portion 11 with respect to the guide portion 15 in the circumferential direction along the guide portion 15 (rotational direction about the position of the fastened portion 14). . The rotation restricting portion 16 serves to restrict rotation of the curved portion 24 of the clamping member 20 beyond the range of existence of the guide portion 15 .

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 sandwiching member 20 is rotatably connected to the connecting portion 13 using the fastening member 30 and holds the brace bolt 70 in a sandwiched state. The sandwiching member 20 is rotatably connected to the connecting portion 13 when the fastening member 30 is incompletely fastened, and holds the brace bolt 70 sandwiched therebetween when the fastening member 30 is fully fastened. The sandwiching member 20 of the present embodiment cooperates with the connecting portion 13 of the base member 10 to hold the brace bolt 70 between itself and the connecting portion 13 . The clamping member 20 is made of, for example, a metal plate. The clamping member 20 has a body portion 21 , a curved portion 24 and rib portions 26 . The 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 body portion 21 is a portion that is superimposed on the base member 10 and serves as a fixed portion to the base member 10 . The body portion 21 is formed in a D shape formed by combining a rectangular area and a semicircular area. An insertion hole 22 through which a shaft portion of a fastening bolt 31 constituting the fastening member 30 can be inserted is formed in the central portion of the body portion 21 . An annular protrusion 23 is formed on the body portion 21 so as to surround the insertion hole 22 . The annular protrusion 23 is formed so as to protrude toward the side opposite 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 body portion 21 to the side opposite to the semicircular region. In this embodiment, the curved portion 24 is formed as a curved plate portion having a circular arc shape with a central angle of approximately 180° when viewed from the side. The curved portion 24 is curved to generally follow the outer surface of the hanging bolt 60 . The curved portion 24 is a portion where the suspension bolt 60 is actually fixed in a state of surrounding the suspension bolt 60, and corresponds to a "fixed portion of the rod-shaped member of 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 projection 25 is formed on the inner surface of the curved portion 24 so as to be locked to the threaded portion on the outer surface of the brace bolt 70 . A plurality of locking projections 25 are dispersedly provided so that they can be locked to the brace bolt 70 at a plurality of locations in the axial direction. By having such locking projections 25, positional deviation of the brace bolt 70 with respect to the rod-shaped body fixture 1 can be suppressed.

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 portion 26 is integrally formed over at least a portion of the body portion 21 and at least a portion of the curved portion 24 on both sides of the sandwiching member 20 in the width direction. In this embodiment, a rib portion 26 is formed over a portion of the body portion 21 and the entire curved portion 24 . The rib portion 26 intersects (perpendicularly in this example) the plate surfaces of the main body portion 21 and the curved portion 24 . By having such a rib portion 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）。 A corner portion of the rib portion 26 on the distal end side of the curved portion 24 is formed in a rounded R shape when viewed from the side, instead of a sharp-pointed shape. The rounded corners of the rib portion 26 serve to guide the brace bolt 70 to the curved portion 24 (which is the fixed portion of the brace bolt 70 in the clamping member 20). That is, the rounded corners of the rib portion 26 constitute a guide portion 26A of the sandwiching member 20 that guides the brace bolt 70 to the curved portion 24 (see FIG. 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 fastening bolts 31 . A fastening bolt 31 that constitutes the fastening member 30 is screwed into the fastening target portion 14 (a 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 through the insertion hole 22 of the clamping member 20 . When the fastening member 30 and the fastened portion 14 are fastened together, the clamping member 20 is connected and fixed between the head portion of the fastening member 30 and the base member 10 via the washer 35 . The brace bolt 70 is sandwiched between the base member 10 and the clamping member 20 and held. The washer 35 has a diameter larger than that of the annular projection 23 of the sandwiching 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 changes gradually according to the position in the axial direction is used. The elastic member 40 is attached to the shaft portion of the fastening bolt 31 that constitutes the fastening member 30 on the opposite side of the clamping member 20 to 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 that constitutes the fastening member 30 with a washer 35 interposed on the head side. Also, the elastic member 40 is attached to the fastening member 30 in a compressed state compared to the steady state (the state in which no external force is applied).

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 urges the clamping member 20 toward the base member 10 side (connecting portion 13 side) while the fastening member 30 is in a loosely tightened state. The "loose tightening state of the fastening member 30" is a state in which the shaft portion of the fastening member 30 is screwed into the fastening target portion 14 and is not completely fastened and fixed. One end of the brace bolt 70 can be temporarily fixed by pressing the clamping member 20 with the brace bolt 70 accommodated in the curved portion 24 against the base member 10 .

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 fixture 1 of the present embodiment can be constructed in a state in which all of the base member 10, clamping member 20, fastening member 30, and elastic member 40 are temporarily assembled (temporary assembled state). In the temporarily assembled state of the rod-shaped body fixture 1, the fastening member 30, to which the washer 35 and the elastic member 40 are attached, passes through the sandwiching member 20 and is screwed into the fastening portion 14 of the base member 10 while being loosened. It is in a closed state. In the temporarily assembled state of the rod-shaped body fixture 1, the pinching member 20 can be rotated around the shaft portion of the fastening member 30 to the extent that it does not interfere with the rotation restricting portion 16 or the mounting member 50 with respect to the base member 10. movably connected (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。 In order to fix the brace bolt 70 to the structure 90 using the rod-like body fixture 1, the following should be done. First, the rod-shaped body fixture 1 is attached to the mounting surface 90 a of the structure 90 in a temporarily assembled state. As described above, the base member 10 is fixed to the structure 90 by inserting the anchor bolts 51 embedded in the structure 90 through the insertion holes 12 of the mounting portions 11 and tightening the nuts 52 in this state.

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 clamping member 20 is roughly adjusted according to the arrangement angle of the brace bolt 70 , and then the brace bolt 70 is attached to the bar fixture 1 . At this time, as shown in FIG. 8, the brace bolt 70 is inserted into a V-shaped receiving portion formed between the guide portion 15 of the base member 10 and the guide portion 26A of the sandwiching member 20 when viewed from the side. Apply in the radial direction of 70. When the brace bolt 70 is pushed in in the radial direction, the brace bolt 70 begins to enter between the base member 10 and the sandwiching member 20 while being guided by the two guide portions 15 and 26A. Then, the sandwiching member 20 is spread by the brace bolt 70 against the base member 10 while resisting the elastic biasing 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 sandwiching member 20 naturally surrounds the brace bolt 70 , and in this state, the elastic restoring force of the elastic member 40 causes the base member 10 and the sandwiching member 20 to come together. A brace bolt 70 is temporarily fixed therebetween. In this way, the brace bolt 70 can be easily temporarily fixed. Further, while the brace bolt 70 is temporarily fixed, the final angle adjustment of the clamping member 20 can be easily performed according to the arrangement angle of the brace bolt 70 . Thus, by using the rod-shaped body fixture 1 of the present embodiment, it is possible to easily deal with various installation angles of the brace bolts 70 according to the situation 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。 After that, the operator can perform the fastening operation of the fastening member 30 while keeping both hands free. Further, the connecting portion 13 is formed in a flat plate shape along the extending direction of the brace bolt 70, and accordingly the fastening member 30 is fastened in the direction orthogonal to the extending direction of the brace bolt 70, so that there is a relatively large margin. The fastening operation of the fastening member 30 can be performed in the space. Therefore, it is possible to perform the fastening operation of the fastening member 30 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 tightened and completely fastened, as shown in FIG. 9, a washer 35 is placed between the head of the fastening member 30 and the connection portion 13 of the base member 10 provided with the portion to be fastened 14 . Then, the holding member 20 is tightened. In this state, the brace bolt 70 can be stably clamped 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, since the washer 35 is formed to have a larger diameter than the annular projection 23 of the clamping member 20, the shaft of the fastening member 30 is positioned between them while the washer 35 is abutted against and supported by the annular projection 23. An annular space A is formed surrounding the part. The annular space A is a flat space formed inside the annular projection 23 of the sandwiching member 20 and having a thickness corresponding to the height of the annular projection 23 protruding from the body portion 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。 This annular space A accommodates an elastic member 40 made of a conical coil spring that assumes a spiral flat shape when highly compressed. The annular space A functions as an elastic member accommodation space. In this way, after the fastening member 30 is fastened, the elastic member 40 is accommodated in the inner space of the annular projection 23 of the clamping member 20, thereby eliminating the influence of the elastic member 40 after fastening the fastening member 30, and the brace is braced. The 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 fixture 1 of the present embodiment, the clamping member 20 holds the brace bolt 70 in a sandwiched state. can be improved. Unlike the conventional bar fixture 100 shown in FIG. 11, it is not necessary to tighten the two nuts 121 and 122 on both sides of the fixing piece 102, so workability can be greatly improved. In addition, since the angle of the sandwiching member 20 can be adjusted while the fastening member 30 is loosely tightened, it is possible to easily adapt to various installation angles of the brace bolt 70 according to the situation 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。 Further, since the elastic member 40 in the compressed state is attached to the fastening member 30 in the loosely tightened state, the brace bolt 70 can be temporarily fixed by the biasing force of the elastic member 40 . In this state, the operator can perform the fastening operation of the fastening member 30 with both hands. Moreover, the fastening operation of the fastening member 30 can be easily performed using, for example, an electric power tool in a relatively large space that spreads laterally of the connecting portion 13 . Therefore, from this point as well, the workability of fixing the brace bolt 70 to the structure 90 can be greatly improved.

（１）上記の実施形態では、挟着部材２０が連結部１３における取付部１１側の面（直角屈曲形状のベース部材１０の屈曲内面）に連結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、挟着部材２０が、連結部１３における取付部１１とは反対側の面（直角屈曲形状のベース部材１０の屈曲外面）に連結されても良い。 [Other embodiments]
(1) In the above-described embodiment, the structure in which the sandwiching member 20 is connected to the surface of the connecting portion 13 on the mounting portion 11 side (the bent inner surface of the base member 10 having a right-angled bent shape) has been described as an example. However, without being limited to such a configuration, the sandwiching member 20 may be connected to the surface of the connecting portion 13 opposite to the mounting portion 11 (the bent outer surface of the base member 10 having a right-angled 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, the configuration in which the mounting portion 11 and the connecting portion 13 are perpendicular to each other has been described as an example. However, without being limited to such a configuration, the mounting portion 11 and the connecting portion 13 may be arranged to intersect to form an acute or obtuse angle. In such a configuration, even in a configuration in which the mounting surface 90a of the structure 90 is not horizontal but inclined, the connecting portion 13 can be vertically positioned by adjusting the crossing angle of the base member 10 side. can be placed.

（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-described embodiment, the position where the insertion hole 12 is formed in the attachment portion 11 and the connection position of the clamping member 20 in the connection portion 13 are separated from each other in the direction along the mounting surface 90a. explained as. However, without being limited to such a configuration, the formation position of the insertion hole 12 and the connection position of the clamping member 20 in the connection 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-described embodiment, an example in which the fastened portion 14 is configured by a burring tap portion has been described. However, without being limited to such a configuration, the fastened portion 14 may be, for example, a fixed nut fixed to a surface of the base member 10 opposite to the clamping member 20 . In this case, an insertion hole through which the shaft portion of the fastening member 30 is inserted is preferably formed at the position of the fastening portion 14 (fixing nut) of 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-described embodiment, the configuration in which the guide portion 15 is formed in the shape of a circular arc around the position of the fastened portion 14 has been described as an example. However, without being limited to such a configuration, the guide portion 15 may be composed of plates having different shapes, or may be composed of a plurality of linear bodies or the like. That is, as long as the brace bolt 70 can be guided at least to the curved portion 24 where the brace bolt 70 is fixed in the clamping member 20, the specific shape of the guide portion 15 may be set arbitrarily. Alternatively, the base member 10 does not necessarily have to be provided with the guide portion 15 .

（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-described embodiment, the example in which the rotation restricting portion 16 is configured by the standing piece arranged in a state orthogonal to the connecting portion 13 has been described. However, without being limited to such a configuration, the rotation restricting portion 16 may be configured by, for example, a protruding portion or the like that protrudes toward the clamping member 20 side. That is, the specific shape of the rotation restricting portion 16 may be set arbitrarily as long as it can restrict the bending portion 24 of the clamping member 20 from rotating beyond the range where the guide portion 15 exists. Alternatively, the base member 10 may not necessarily be provided with the rotation restricting portion 16 .

（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 configuration in which the connecting portion 13 is formed in a flat plate shape has been described as an example. However, the connecting portion 13 may be formed non-flat without being limited to such a configuration. For example, as shown in FIG. 10, the connecting portion 13 may be formed with an annular protrusion 18 that protrudes toward the side opposite to the mounting surface of the clamping member 20 (the curved 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 is not provided with the to-be-fastened portion 14 , and instead of the to-be-fastened portion 14 , the fastening member 30 includes a fastening nut 33 with which the fastening bolt 31 is screwed. . A hexagonal recess corresponding to the outer shape of the fastening nut 33 is formed on the inner peripheral side of the annular projection 18 . The fastening nut 33 is engaged. This concave portion functions as a co-rotation preventing portion 19 that prevents co-rotation of the fastening nut 33 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 sandwiching member 20 described in the above embodiment are merely examples and are not limited to such configurations. The specific shape can be arbitrarily set as long as at least each function can be exhibited. For example, as shown in FIG. 11, the base member 10 may be configured by an L-shaped plate member having a constant width. As shown in the figure, the clamping member 20 is formed in a tray shape (a box shape with an opening on the bottom side) having a main body portion 21 constituting an upper surface portion and hanging wall portions 27 hanging down from the outer edge thereof. Also good. In this case, a pair of notch portions 28 formed in the hanging wall portion 27 along the outer surface of the brace bolt 70 may constitute the fixing portion of the brace bolt 70 . Of course, it is also possible to adopt other shapes for the base member 10 and the sandwiching 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 of a configuration in which the clamping member 20 and the connecting portion 13 of the base member 10 hold the brace bolt 70 in a state of being sandwiched between the clamping member 20 and the connecting portion 13 has been described. However, without being limited to such a configuration, for example, the sandwiching member 20 may be connected to the base member 10 while holding the brace bolt 70 in a state where the brace bolt 70 is sandwiched by itself. In this case, the clamping member 20 may be composed of a single member (for example, a plate-like member having a loop portion) or two members (for example, a set of a plate-like member and a plate-like 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-described embodiment, the construction procedure was described mainly assuming that the brace bolt 70 is slid in the radial direction and inserted into the gap between the base member 10 and the clamping member 20 from the side. . However, without being limited to such a configuration, the brace bolt 70 may be axially (vertically) inserted into the gap between the base member 10 and the sandwiching 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, the configuration in which the elastic member 40 is attached to the fastening member 30 has been described as an example. However, the elastic member 40 does not necessarily have to be attached to the fastening member 30 without being limited to such a configuration. In this case, the temporary holding function of the brace bolts 70 is lost, but it is possible to deal with various installation angles of the brace bolts 70 according to the situation of each construction site, and the brace bolts 70 are attached to the structure 90. It is also possible to significantly improve workability related to fixing.

（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 hereinafter) are applied in combination with the configurations disclosed in other embodiments unless there is a contradiction. It is also possible to Regarding other configurations, the embodiments disclosed in this specification are examples in all respects, and can be modified as appropriate without departing from the scope of the present disclosure.
