Description
本発明は、構造物の天井面から設備機器等を懸垂する吊ボルトに、地震等による振動を抑制するための振止ボルトを取り付けるためなどに用いられるボルト取付金具に関する。 The present invention relates to a bolt mounting fixture that is used to attach anti-vibration bolts to suspension bolts that suspend equipment from the ceiling surface of a structure in order to suppress vibrations caused by earthquakes, etc.
地震時に設備機器（ケーブルラックや機器、配管を載置する鋼材）の損傷や落下を減らすため、振れ止めが施工される。自重支持用の吊り材より斜材を連結させて、（軸方向や軸直角方向の）振れ止め施工するための振止金具が考案されてきた。具体的には、例えば、三方向の斜め支持ボルトに接続することが可能な振止金具として、一対の斜め支持体を左右両端部に連結する固定板を設け、固定板の左右両端部に一対のＬ形金具を固定し、各Ｌ形金具の対向した開放端部間から吊りボルトを挿入するように構成し、開放端部連結時に吊りボルトが挟着されるように構成し、Ｌ形金具の開放端部に第三の斜め支持体を着脱自在に設けたものが知られている（例えば、特許文献１参照。）。 Anti-vibration devices are installed to prevent damage or falling of equipment (cable racks, equipment, and steel materials on which piping is placed) during earthquakes. Anti-vibration devices have been devised to connect diagonal members to a hanging member for supporting the load of the equipment itself and to install anti-vibration devices (in the axial direction and perpendicular to the axis). Specifically, for example, an anti-vibration device that can be connected to diagonal support bolts in three directions is known in which a fixed plate is provided to connect a pair of diagonal supports to both left and right ends, a pair of L-shaped fittings are fixed to both left and right ends of the fixed plate, a suspension bolt is inserted between the opposing open ends of each L-shaped fitting, the suspension bolt is clamped when the open ends are connected, and a third diagonal support is detachably provided at the open end of the L-shaped fitting (see, for example, Patent Document 1).
上記のような振止金具では、部品の点数が多いとともに各部品を固定する固定箇所が多く、作業性が低下しがちであった。 Anti-vibration brackets like the one above have a large number of parts and many fixing points for fixing each part, which tends to reduce workability.
本発明は、上記の点に鑑みてなされたものであり、少ない部品点数で装着を容易にし、作業性を容易に向上させられるようにすることを目的としている。 The present invention was made in consideration of the above points, and aims to make installation easier with a small number of parts, and to easily improve workability.

本発明では、少ない部品点数で装着を容易にし、作業性を容易に向上させることができる。 The present invention allows for easy installation with a small number of parts, and can easily improve workability.
以下、本発明の実施形態を図面に基づいて詳細に説明する。なお、以下の各実施形態において、他の実施形態と同様の機能を有する構成要素については同一の符号を付して説明を省略する。 Embodiments of the present invention will be described in detail below with reference to the drawings. In each of the following embodiments, components having the same functions as those in other embodiments will be given the same reference numerals and will not be described.
（実施形態１）
吊ボルトＡ（第１のボルト）に振止ボルトＢ～Ｄ（第２～第４のボルト）を連結する実施形態１のボルト取付金具１００は、図１～図３に示すように、吊ボルトＡを固定する吊ボルト固定部材１１０（第１のボルト固定部材）と、ベース部材１２０と、振止ボルトＢ～Ｄを固定する３つの振止ボルト固定部材１３０・１３０’・１３０”（第２～４のボルト固定部材）とを有している。吊ボルト固定部材１１０と、その両側に配置される２つの振止ボルトＢ・Ｃ用の振止ボルト固定部材１３０・１３０’とは、結合ボルト１４０（第１の結合ボルト、第１の結合部材）によって結合されるとともに、吊ボルト固定部材１１０と、もう１つの振止ボルトＤ用の振止ボルト固定部材１３０とは、結合ボルト１４１（第２の結合ボルト、第２の結合部材）によって結合されている。
(Embodiment 1)
As shown in Figures 1 to 3, the bolt mounting bracket 100 of embodiment 1, which connects anti-vibration bolts B to D (second to fourth bolts) to a hanging bolt A (first bolt), has a hanging bolt fixing member 110 (first bolt fixing member) that fixes the hanging bolt A, a base member 120, and three anti-vibration bolt fixing members 130, 130', 130" (second to fourth bolt fixing members) that fix the anti-vibration bolts B to D. The hanging bolt fixing member 110 and the anti-vibration bolt fixing members 130, 130' for the two anti-vibration bolts B and C arranged on either side of it are connected by a connecting bolt 140 (first connecting bolt, first connecting member), and the hanging bolt fixing member 110 and the anti-vibration bolt fixing member 130 for the other anti-vibration bolt D are connected by a connecting bolt 141 (second connecting bolt, second connecting member).
上記吊ボルト固定部材１１０は、ベース部材１１１と押さえ部材１１２とによって吊ボルトＡを挟持するように構成されている。より詳しくは、ベース部材１１１は、底壁部１１１ａと、これに立設され、係合凹部１１１ｃが形成された１対の側壁部１１１ｂとを有している。押さえ部材１１２は、底壁部１１２ａと、これに立設された側壁部１１２ｂとを有し、底壁部１１２ａの押さえ部１１２ｃによって、ベース部材１１１の係合凹部１１１ｃに嵌まり込んだ吊ボルトＡを押し付けるようになっている。 The suspension bolt fixing member 110 is configured to clamp the suspension bolt A between a base member 111 and a pressing member 112. More specifically, the base member 111 has a bottom wall portion 111a and a pair of side walls 111b erected thereon and having an engagement recess 111c formed therein. The pressing member 112 has a bottom wall portion 112a and a side wall portion 112b erected thereon, and the pressing portion 112c of the bottom wall portion 112a presses the suspension bolt A fitted into the engagement recess 111c of the base member 111.
ベース部材１１１には、側壁部１１１ｂに形成された突出部が直角に折り曲げられた当接部１１１ｄが設けられる一方、押さえ部材１１２には、側壁部１１２ｂの一部が切り欠かれた当接部１１２ｄが設けられ、上記当接部１１１ｄ・１１２ｄを支点として、ベース部材１１１と押さえ部材１１２とが相対的に（一方が他方に対して）揺動可能に構成されている。そこで、ベース部材１１１および押さえ部材１１２の一端側の押圧部１１１ｅ・１１２ｅを押圧することにより他端側の係合凹部１１１ｃと押さえ部１１２ｃとの間（挟持部）が開く一方、上記押圧部１１１ｅ・１１２ｅの押圧を解除することにより、後述する圧縮コイルバネ１６０・１６０’の付勢力によって吊ボルトＡが挟持されるようになっている。 The base member 111 is provided with an abutment portion 111d formed by bending a protrusion formed on the side wall portion 111b at a right angle, while the pressing member 112 is provided with an abutment portion 112d formed by cutting out a part of the side wall portion 112b, and the base member 111 and the pressing member 112 are configured to be able to swing relatively (one against the other) with the abutment portions 111d and 112d as fulcrums. Thus, by pressing the pressing portions 111e and 112e on one end side of the base member 111 and the pressing member 112, the gap (clamping portion) between the engagement recess 111c on the other end side and the pressing portion 112c opens, while by releasing the pressing of the pressing portions 111e and 112e, the suspension bolt A is clamped by the urging force of the compression coil springs 160 and 160' described later.
振止ボルト固定部材１３０・１３０’・１３０”は、それぞれ、ボルト孔１３２が形成された略矩形の底壁部１３１と、その各辺から立設される断面四角形状の側壁部１３３とを有している。上記側壁部１３３のうち、対向する１対の側壁部１３３には、振止ボルトＢ～Ｄが嵌まり込む係合凹部１３４が形成されている。 Each of the anti-vibration bolt fixing members 130, 130', and 130" has a substantially rectangular bottom wall portion 131 with a bolt hole 132 formed therein, and side wall portions 133 with a square cross section erected from each side of the bottom wall portion 131. Of the side wall portions 133, a pair of opposing side wall portions 133 are formed with engagement recesses 134 into which the anti-vibration bolts B to D fit.
振止ボルト固定部材１３０は、吊ボルト固定部材１１０におけるベース部材１１１の底壁部１１１ａ側に圧縮コイルバネ１６０を介して配置され、振止ボルトＢを固定するようになっている。また、振止ボルト固定部材１３０’は、吊ボルト固定部材１１０における押さえ部材１１２の底壁部１１２ａ側に圧縮コイルバネ１６０’を介して配置され、振止ボルトＣを固定するようになっている。すなわち、振止ボルト固定部材１３０・１３０’は、吊ボルトＡの方向である第１の方向に直交する第２の方向の一方側または他方側に設けられ、振止ボルトＢ・Ｃを上記第２の方向に直交する面内で回転可能な所定の位置に固定するようになっている。 The anti-vibration bolt fixing member 130 is arranged on the bottom wall portion 111a side of the base member 111 in the hanging bolt fixing member 110 via a compression coil spring 160, and is adapted to fix the anti-vibration bolt B. The anti-vibration bolt fixing member 130' is arranged on the bottom wall portion 112a side of the pressing member 112 in the hanging bolt fixing member 110 via a compression coil spring 160', and is adapted to fix the anti-vibration bolt C. In other words, the anti-vibration bolt fixing members 130 and 130' are provided on one side or the other side of a second direction perpendicular to the first direction, which is the direction of the hanging bolt A, and are adapted to fix the anti-vibration bolts B and C at predetermined positions that are rotatable within a plane perpendicular to the second direction.
上記吊ボルト固定部材１１０と振止ボルト固定部材１３０・１３０’とは、それぞれのボルト孔１１１ｆ・１１２ｆ・１３２に挿通される結合ボルト１４０とナット１５０とによって結合され、吊ボルトＡ、および振止ボルトＢ・Ｃが固定されるようになっている。 The hanging bolt fixing member 110 and the vibration-prevention bolt fixing members 130 and 130' are connected by a connecting bolt 140 and a nut 150 inserted through the respective bolt holes 111f, 112f, and 132, so that the hanging bolt A and the vibration-prevention bolts B and C are fixed.
振止ボルト固定部材１３０”は、吊ボルト固定部材１１０におけるベース部材１１１の上記１対の側壁部１１１ｂを接続する接続側壁部１１１ｇ側に、ベース部材１２０、および圧縮コイルバネ１６０”を介して配置され、振止ボルトＤを固定するようになっている。すなわち、振止ボルト固定部材１３０”は、吊ボルト固定部材１１０に対して、吊ボルトＡの方向（第１の方向）と、これに直交する方向（第２の方向）とに直交する方向（第３の方向）側に設けられ、振止ボルトＤを上記第１および第２の方向を含む面に平行な面内で回転可能な所定の位置に固定するようになっている。 The anti-vibration bolt fixing member 130" is arranged on the side of the connecting side wall portion 111g that connects the pair of side wall portions 111b of the base member 111 of the hanging bolt fixing member 110 via the base member 120 and the compression coil spring 160", and is configured to fix the anti-vibration bolt D. In other words, the anti-vibration bolt fixing member 130" is provided on the side of the hanging bolt fixing member 110 in a direction (third direction) perpendicular to the direction of the hanging bolt A (first direction) and a direction (second direction) perpendicular thereto, and is configured to fix the anti-vibration bolt D at a predetermined position that is rotatable within a plane parallel to the plane including the first and second directions.
上記吊ボルト固定部材１１０、ベース部材１２０、および振止ボルト固定部材１３０”は、ボルト孔１１１ｈ・１２１・１３２に挿通される結合ボルト１４１とナット１５１とによって結合され、吊ボルトＤが固定されるようになっている。 The hanging bolt fixing member 110, the base member 120, and the vibration-proof bolt fixing member 130" are connected by a connecting bolt 141 and a nut 151 inserted through the bolt holes 111h, 121, and 132, and the hanging bolt D is fixed.
圧縮コイルバネ１６０・１６０’は、その付勢力により通常時は押さえ部材１１２の押さえ部１１２ｃがベース部材１１１の側壁部１１１ｂにおける係合凹部１１１ｃを閉塞した状態とする。そして、ベース部材１１１および押さえ部材１１２の押圧部１１１ｅ・１１２ｅが押圧操作されることにより、当接部１１１ｄ・１１２ｄを支点としてベース部材１１１と押さえ部材１１２とが相対的に揺動して係合凹部１１１ｃが開放された状態となり、吊ボルトＡを嵌め込んで、仮止し得るようになっている。 The compression coil springs 160 and 160' normally have the pressing portion 112c of the pressing member 112 blocking the engagement recess 111c in the side wall portion 111b of the base member 111 due to their biasing force. Then, when the pressing portions 111e and 112e of the base member 111 and the pressing member 112 are pressed, the base member 111 and the pressing member 112 swing relatively with the abutment portions 111d and 112d as fulcrums, opening the engagement recess 111c, and allowing the suspension bolt A to be fitted in and temporarily secured.
また、圧縮コイルバネ１６０・１６０’・１６０”は、吊ボルト固定部材１１０側よりも振止ボルト固定部材１３０・１３０’・１３０”側の方が巻き線径が大きい円錐螺旋状に形成され、その素線の外径および間隔を、圧縮コイルバネ１６０・１６０’・１６０”が振止ボルトＢ～Ｄの外周に当接し、振止ボルト固定部材１３０・１３０’・１３０”の係合凹部１３４の奥へ向けて押圧するような大きさに設定し、圧縮コイルバネ１６０・１６０’・１６０”の素線の振止ボルトＢ～Ｄの外周への当接を確実にして、振止ボルトＢ～Ｄの仮止が容易にできるようになっている。 The compression coil springs 160, 160', 160" are formed in a conical spiral shape with a larger winding diameter on the anti-vibration bolt fixing member 130, 130', 130" side than on the suspension bolt fixing member 110 side. The outer diameter and spacing of the wire are set to a size that allows the compression coil springs 160, 160', 160" to abut against the outer periphery of the anti-vibration bolts B to D and press toward the back of the engagement recesses 134 of the anti-vibration bolt fixing members 130, 130', 130". This ensures that the wire of the compression coil springs 160, 160', 160" abuts against the outer periphery of the anti-vibration bolts B to D, making it easy to temporarily fasten the anti-vibration bolts B to D.
上記のようなボルト取付金具１００は、ナット１５０（または結合ボルト１４０）を適度に締め込むことによって、吊ボルト固定部材１１０と振止ボルト固定部材１３０・１３０’の側壁部１３３との間の間隔が振止ボルトＢ・Ｃが通過し得る程度で、かつ、圧縮コイルバネ１６０・１６０’の付勢力により、吊ボルト固定部材１１０の押さえ部材１１２の押さえ部１１２ｃがベース部材１１１の係合凹部１１１ｃ付近に所定の押圧力で押し付けられるようにされて用いられる。この状態で、ベース部材１１１および押さえ部材１１２の押圧部１１１ｅ・１１２ｅが押圧操作されると、押さえ部材１１２の押さえ部１１２ｃとベース部材１１１の係合凹部１１１ｃ付近との間隔が開き、吊ボルトＡを係合凹部１１１ｃに嵌め込み、押さえ部材１１２により押圧して仮止することが容易にできる。 The above-mentioned bolt mounting fixture 100 is used by appropriately tightening the nut 150 (or the connecting bolt 140) so that the gap between the hanging bolt fixing member 110 and the side wall portion 133 of the anti-vibration bolt fixing member 130/130' is large enough for the anti-vibration bolts B/C to pass through, and the biasing force of the compression coil springs 160/160' presses the pressing portion 112c of the pressing member 112 of the hanging bolt fixing member 110 against the vicinity of the engagement recess 111c of the base member 111 with a predetermined pressing force. In this state, when the pressing portions 111e/112e of the base member 111 and the pressing member 112 are pressed, the gap between the pressing portion 112c of the pressing member 112 and the vicinity of the engagement recess 111c of the base member 111 opens, and the hanging bolt A can be easily fitted into the engagement recess 111c and temporarily fixed by pressing it with the pressing member 112.
次に、吊ボルト固定部材１１０と振止ボルト固定部材１３０・１３０’の側壁部１３３との間に振止ボルトＢ・Ｃを押し込むと、圧縮コイルバネ１６０・１６０’の素線が振止ボルトＢ・Ｃの外周に当接し、振止ボルトＢ・Ｃを仮止することが容易にできる。同様に、ベース部材１２０と振止ボルト固定部材１３０”の側壁部１３３との間に振止ボルトＤを押し込むと、圧縮コイルバネ１６０”の素線が振止ボルトＤの外周に当接し、振止ボルトＤを仮止することが容易にできる。 Next, when the anti-vibration bolts B and C are pushed between the hanging bolt fixing member 110 and the side wall portion 133 of the anti-vibration bolt fixing member 130 and 130', the wire of the compression coil spring 160 and 160' comes into contact with the outer periphery of the anti-vibration bolts B and C, making it easy to temporarily secure the anti-vibration bolts B and C. Similarly, when the anti-vibration bolt D is pushed between the base member 120 and the side wall portion 133 of the anti-vibration bolt fixing member 130", the wire of the compression coil spring 160" comes into contact with the outer periphery of the anti-vibration bolt D, making it easy to temporarily secure the anti-vibration bolt D.
そこで、ナット１５０を締め込むと、振止ボルト固定部材１３０、吊ボルト固定部材１１０、および振止ボルト固定部材１３０’が密着して、振止ボルト固定部材１３０・１３０’、の係合凹部１３４に嵌まり込んだ振止ボルトＢ・Ｃを確実に固定することが容易にできる。また、ナット１５１を締め込むと、ベース部材１２０と、振止ボルト固定部材１３０”とが密着して、振止ボルト固定部材１３０”、の係合凹部１３４に嵌まり込んだ振止ボルトＤを確実に固定することが容易にできる。 When the nut 150 is tightened, the anti-vibration bolt fixing member 130, the hanging bolt fixing member 110, and the anti-vibration bolt fixing member 130' come into close contact with each other, making it easy to reliably fix the anti-vibration bolts B and C that are fitted into the engagement recesses 134 of the anti-vibration bolt fixing members 130 and 130'. Also, when the nut 151 is tightened, the base member 120 and the anti-vibration bolt fixing member 130" come into close contact with each other, making it easy to reliably fix the anti-vibration bolt D that is fitted into the engagement recess 134 of the anti-vibration bolt fixing member 130".
上記のように、２つのナット１５０・１５１（または２本の結合ボルト１４０・１４１）を締め付けることによって、吊ボルトＡ、および振止ボルトＢ～Ｄを容易に固定することができ、確実な仮止めを容易にしつつ、作業性を高めることが容易にできる。 As described above, by tightening the two nuts 150 and 151 (or the two connecting bolts 140 and 141), the hanging bolt A and the anti-vibration bolts B to D can be easily fixed, facilitating a secure temporary fastening while also improving workability.
また、結合ボルト１４０・１４１やナット１５０・１５１など取付に必要なものが組み込まれているため、容易に片手で作業できるとともに、高所作業時の安全性を高くすることが容易にできる。 In addition, the parts necessary for installation, such as the connecting bolts 140 and 141 and nuts 150 and 151, are built in, making it easy to work with one hand and increasing safety when working at height.
上記のように圧縮コイルバネ１６０・１６０’・１６０”が振止ボルトＢ～Ｄを振止ボルト固定部材１３０・１３０’・１３０”の係合凹部１３４の奥へ向けて押圧するように設定されていることによって、振止ボルトＢ～Ｄを仮止することが容易にでき、各ボルトＡ～Ｄの固定位置の調整も容易にできる。 As described above, the compression coil springs 160, 160', and 160" are set to press the anti-vibration bolts B to D toward the back of the engagement recesses 134 of the anti-vibration bolt fixing members 130, 130', and 130". This makes it easy to temporarily fix the anti-vibration bolts B to D and also makes it easy to adjust the fixing positions of the bolts A to D.
（実施形態２）
吊ボルト固定部材１１０は、上記のように押圧部１１１ｅ・１１２ｅが設けられるのに変えて、またはこれが設けられるとともに、例えば図４に示すように、ベース部材１１１および／または押さえ部材１１２に、吊ボルトＡを押し付けることによりベース部材１１１と押さえ部材１１２との間隔が拡がる方向の力を作用させる傾斜部１１１ｉ・１１２ｇが形成されるようにしてもよい。この場合にも、やはり、吊ボルトＡを吊ボルト固定部材１１０に挟持させて仮止めすることが容易にできるとともに、２本の結合ボルト１４０・１４１を締め付けることによって、吊ボルトＡ、および振止ボルトＢ～Ｄを容易に固定することができ、確実な仮止めを容易にしつつ、作業性を高めることが容易にできる。
(Embodiment 2)
4, the suspension bolt fixing member 110 may be provided with inclined portions 111i and 112g that apply a force in a direction that widens the gap between the base member 111 and the pressing member 112 by pressing the suspension bolt A against the base member 111 and/or the pressing member 112. In this case, too, the suspension bolt A can be easily clamped between the suspension bolt fixing member 110 and temporarily fixed, and the suspension bolt A and the anti-vibration bolts B to D can be easily fixed by tightening the two connecting bolts 140 and 141, facilitating reliable temporary fixing while easily improving workability.
（その他の事項）
なお、上記の例では吊ボルト固定部材１１０に吊ボルトＡが固定され、振止ボルト固定部材１３０・１３０’・１３０”に振止ボルトＢ～Ｄが固定される例を示したが、それぞれ、どのようなボルトを固定するかは種々設定可能である。
(Other matters)
In the above example, the suspension bolt A is fixed to the suspension bolt fixing member 110, and the anti-vibration bolts B to D are fixed to the anti-vibration bolt fixing members 130, 130', and 130'', but it is possible to set various types of bolts to be fixed in each case.
また、吊ボルト固定部材１１０に吊ボルトＡを挟持させたり、振止ボルトＢ～Ｄを振止ボルト固定部材１３０・１３０’・１３０”の係合凹部１３４の奥へ向けて押圧する付勢力を作用させたりするためには、圧縮コイルバネ１６０等に限らず、例えばＣ字形状に撓ませた板バネを用いるなどしてもよい。より具体的には、例えば、板バネの一端部が振止ボルト固定部材１３０等の底壁部１３１に当接するとともに、板バネの中間部が吊ボルト固定部材１１０に当接することにより、吊ボルトＡが挟持されて仮止めされるようにしたり、板バネの他端部が振止ボルトＢ～Ｄに当接して、振止ボルトＢ～Ｄを仮止めしたりすることができる。 In addition, in order to clamp the hanging bolt A to the hanging bolt fixing member 110 or to apply a biasing force that presses the anti-vibration bolts B to D toward the back of the engagement recesses 134 of the anti-vibration bolt fixing members 130, 130', and 130", it is possible to use, for example, a leaf spring bent into a C-shape, rather than being limited to the compression coil spring 160. More specifically, for example, one end of the leaf spring abuts against the bottom wall portion 131 of the anti-vibration bolt fixing member 130, etc., and the middle portion of the leaf spring abuts against the hanging bolt fixing member 110, thereby clamping and temporarily fixing the hanging bolt A, or the other end of the leaf spring abuts against the anti-vibration bolts B to D, temporarily fixing the anti-vibration bolts B to D.
また、上記の例では、１本の結合ボルト１４０によって吊ボルト固定部材１１０、振止ボルト固定部材１３０・１３０’が互いに結合されて、吊ボルトＡ、および振止ボルトＢ・Ｃが挟持、固定される例を示したが、これに限らず、例えば吊ボルトＡを吊ボルト固定部材１１０に挟持固定させるボルトと、振止ボルトＢを振止ボルト固定部材１３０と吊ボルト固定部材１１０との間に挟持固定させるボルトと、振止ボルトＣを振止ボルト固定部材１３０’と吊ボルト固定部材１１０との間に挟持固定させるボルトとを、それぞれ別個に設けてもよい。 In the above example, the hanging bolt fixing member 110 and the anti-vibration bolt fixing members 130 and 130' are connected to each other by a single connecting bolt 140, and the hanging bolt A and the anti-vibration bolts B and C are clamped and fixed. However, this is not limited to the above. For example, a bolt that clamps and fixes the hanging bolt A to the hanging bolt fixing member 110, a bolt that clamps and fixes the anti-vibration bolt B between the anti-vibration bolt fixing member 130 and the hanging bolt fixing member 110, and a bolt that clamps and fixes the anti-vibration bolt C between the anti-vibration bolt fixing member 130' and the hanging bolt fixing member 110 may each be provided separately.
また、吊ボルトＡを吊ボルト固定部材１１０に挟持固定させるボルトとしては、例えば図４に示すように振止ボルトＤを挟持固定する結合ボルト１４１を兼ねさせたり、別途、同様のボルトを設けたりしてもよい。また、例えば図５に示すように吊ボルト固定部材１１０がベース部材１１３とフック部材１１４とを備え、上記フック部材１１４をフック部材引込ボルト１４２とナット１５２によりベース部材１１３に向けて引き込むことによって、吊ボルトＡがベース部材１１３とフック部材１１４との間に挟持固定されるようにしてもよい。さらに、上記のようなフック部材引込ボルト１４２が、図４に示すような振止ボルトＤを挟持固定する結合ボルト１４１を兼ねるようにしてもよい。 The bolt that clamps and fixes the hanging bolt A to the hanging bolt fixing member 110 may also serve as a connecting bolt 141 that clamps and fixes the anti-vibration bolt D, as shown in FIG. 4, or a similar bolt may be provided separately. The hanging bolt fixing member 110 may also include a base member 113 and a hook member 114, as shown in FIG. 5, and the hanging bolt A may be clamped and fixed between the base member 113 and the hook member 114 by drawing the hook member 114 toward the base member 113 with a hook member drawing bolt 142 and a nut 152. The hook member drawing bolt 142 may also serve as a connecting bolt 141 that clamps and fixes the anti-vibration bolt D, as shown in FIG. 4.
また、圧縮コイルバネ１６０・１６０’は、振止ボルト固定部材１３０・１３０’と吊ボルト固定部材１１０との間に設けられるのに限らず、振止ボルト固定部材１３０・１３０’の少なくとも一方における吊ボルト固定部材１１０と反対側に設けられるようにしてもよい。同様に、圧縮コイルバネ１６０”は、振止ボルト固定部材１３０”における吊ボルト固定部材１１０と反対側に設けられるようにしてもよい。これらによっても、吊ボルトＡや振止ボルトＢ～Ｄを吊ボルト固定部材１１０の係合凹部１１１ｃや振止ボルト固定部材１３０・１３０’・１３０”の係合凹部１３４の奥へ向けて押圧する付勢力を作用させて仮止め可能にすることが容易にできる。 In addition, the compression coil springs 160 and 160' are not limited to being provided between the anti-vibration bolt fixing members 130 and 130' and the hanging bolt fixing members 110, but may be provided on the opposite side of the hanging bolt fixing members 110 in at least one of the anti-vibration bolt fixing members 130 and 130'. Similarly, the compression coil springs 160" may be provided on the opposite side of the hanging bolt fixing member 110 in the anti-vibration bolt fixing member 130". This also makes it easy to apply a biasing force that presses the hanging bolt A and the anti-vibration bolts B to D toward the back of the engagement recesses 111c of the hanging bolt fixing member 110 and the engagement recesses 134 of the anti-vibration bolt fixing members 130, 130', and 130". This makes it easy to temporarily fasten them.
