Description
本発明は、棒状材用支持具に関する。 The present invention relates to a rod support.
天井スラブ等から吊りボルトを吊り下げ、この吊りボルトに振れ止めボルト（補助ボルト）を固定するための吊りボルト用支持具が知られている（例えば、特許文献１参照）。吊りボルト用支持具は、吊りボルトに対して任意の高さ位置に金具を位置決めし、振れ止めボルトを任意の角度で支持する構造を有している。 There is a known support for a hanging bolt that is used to hang a hanging bolt from a ceiling slab or the like and to secure an anti-sway bolt (auxiliary bolt) to the hanging bolt (see, for example, Patent Document 1). The support for a hanging bolt has a structure that positions a metal fitting at any height relative to the hanging bolt and supports the anti-sway bolt at any angle.
上記の吊りボルト用支持具を用いた作業において、作業者は、一方の手で吊りボルトと振れ止めボルトとを挟み込んだ吊りボルト用支持具を持ちながら、他方の手でボルトを締める必要があり、この作業自体に慣れが必要であった。そのため、簡単な操作で、吊りボルトに対して振れ止めボルトを固定することができる支持具が望まれている。 When using the above-mentioned suspension bolt support, the worker must hold the suspension bolt support, which holds the suspension bolt and the anti-sway bolt, in one hand while tightening the bolt with the other hand, and this task itself requires some getting used to. Therefore, there is a demand for a support that can fix the anti-sway bolt to the suspension bolt with a simple operation.
本発明に係る棒状材用支持具は、第１棒状材に対して第２棒状材を固定するために用いられ、第１支持体と、第１支持体に対向して配置される第２支持体と、第１支持体、第２支持体それぞれの貫通孔に挿入され、第１支持体と第２支持体とをそれらの間に第１棒状材及び第２棒状材を挟んで締結するための締結ボルトと、第１棒状材から第１支持体が脱落しないように仮止めするために、第１棒状材を第１支持体に対して押圧するための補助板と、を具備する。 The rod-shaped material support device of the present invention is used to fix a second rod-shaped material to a first rod-shaped material and comprises a first support, a second support arranged opposite the first support, fastening bolts inserted into the through holes of the first support and the second support for fastening the first support and the second support with the first rod-shaped material and the second rod-shaped material sandwiched between them , and an auxiliary plate for pressing the first rod-shaped material against the first support to temporarily secure the first support so that it does not fall off from the first rod-shaped material .
本発明によれば、吊りボルト等の棒状材に対して振れ止めボルト等の棒状材を簡単な操作で固定することができる。 According to the present invention, a rod-shaped material such as a vibration prevention bolt can be fixed to a rod-shaped material such as a hanging bolt with a simple operation.
図１は本実施形態に係る吊りボルト用支持具１０の使用状態の一例を示している。この例では、吊りボルトＢを介して支持部材Ｒが天井スラブTに吊下支持されている。この支持部材Ｒにはラック等が設置される。天井スラブTには、吊りボルトＢの振れ止めに使用される振れ止めボルトＳが金具等を介して取り付けられている。吊りボルト用支持具１０は、吊りボルトＢに対して斜めに配置される振れ止めボルトＳと吊りボルトＢとが交差する部分に取り付けられ、それらを固定する用途に使用される。なお、吊りボルト用支持具１０が使用される用途は上記に限定されることはなく、２本の全ネジボルトの位置関係を固定する様々な用途に使用することができる。例えば、図１において、本実施形態に係る吊りボルト用支持具１０を２本の振れ止めボルトＳが交差する位置に配置し、これらを固定する用途として用いることができる。 Figure 1 shows an example of the use of the suspension bolt support 10 according to this embodiment. In this example, a support member R is suspended from a ceiling slab T via a suspension bolt B. A rack or the like is installed on this support member R. A vibration prevention bolt S used to prevent the suspension bolt B from vibrating is attached to the ceiling slab T via a metal fitting or the like. The suspension bolt support 10 is attached to the intersection of the vibration prevention bolt S, which is arranged diagonally with respect to the suspension bolt B, and the suspension bolt B, and is used to fix them. Note that the applications in which the suspension bolt support 10 is used are not limited to the above, and it can be used for various applications in which the positional relationship of two fully threaded bolts is fixed. For example, in Figure 1, the suspension bolt support 10 according to this embodiment is placed at the intersection of two vibration prevention bolts S, and can be used to fix them.
図２乃至図４に示すように、吊りボルト用支持具１０は第１支持体２０と、第１支持体２０に対向配置される第２支持体３０と、第１支持体２０と第２支持体３０とを締結する締結ボルト５０と、を有する。 As shown in Figures 2 to 4, the suspension bolt support 10 has a first support 20, a second support 30 arranged opposite the first support 20, and a fastening bolt 50 that fastens the first support 20 and the second support 30.
第１支持体２０は金属製であり、略二等辺三角形状に構成される。具体的には、第１支持体２０は、第１支持体本体２１を有する。第１支持体本体２１は、略二等辺三角形状の第１板体２２と、二等辺三角形の底辺に対応する第１板体２２の周縁部に第１板体２２に対して垂直に設けられた第１保持片２３と、二等辺三角形の２本の等辺に対応する第１板体２２の周縁部に第１板体２２に対して傾斜して設けられる第１圧着片２４とを有する。以下、第１板体２２の第１保持片２３、第１圧着片２４が設けられた側の面を裏面、その反対側の面を表面としてそれぞれを区別する。 The first support 20 is made of metal and is configured in a substantially isosceles triangle shape. Specifically, the first support 20 has a first support body 21. The first support body 21 has a substantially isosceles triangle-shaped first plate 22, a first holding piece 23 provided perpendicular to the first plate 22 on the periphery of the first plate 22 corresponding to the base of the isosceles triangle, and a first pressure piece 24 provided at an angle to the first plate 22 on the periphery of the first plate 22 corresponding to the two equal sides of the isosceles triangle. Hereinafter, the surface of the first plate 22 on which the first holding piece 23 and the first pressure piece 24 are provided will be referred to as the back surface, and the opposite surface will be referred to as the front surface.
第１板体２２の略中央には、締結ボルト５０が挿入される孔部２２ａが開けられている。孔部２２ａは締結ボルト５０の矩形状のネック部の外周に係合する矩形状に形成されている。 A hole 22a into which the fastening bolt 50 is inserted is provided at approximately the center of the first plate 22. The hole 22a is formed in a rectangular shape that engages with the outer periphery of the rectangular neck portion of the fastening bolt 50.
第１保持片２３の両側縁部と第１圧着片２４の両側縁部との間には、吊りボルトＢの外径より僅かに大きい隙間が設けられる。この隙間に吊りボルトＢが通される。後述の補助板４０は、第１保持片２３の先端縁及び第１圧着片２４の先端縁に接触する位置またはわずかな隙間を隔てた位置に配置される。第１板体２２、第１保持片２３、第１圧着片２４の両側縁部及び補助板４０により規定される空間は吊りボルトＢを収容する収容部Ｑ１として機能する。この収容部Ｑ１の高さ、すなわち第１板体２２の裏面から第１保持片２３及び第１圧着片２４の先端縁までの高さは、吊りボルトＢの直径よりも短い。第１板体２２の裏面には、収容部Ｑ１に収容された吊りボルトＢのネジ溝に係合する複数の第１突起部２２ｂが第１保持片２３に沿って分散配置される。 Between both side edges of the first holding piece 23 and both side edges of the first crimping piece 24, there is a gap slightly larger than the outer diameter of the hanging bolt B. The hanging bolt B is passed through this gap. The auxiliary plate 40 described later is placed in a position where it contacts the tip edge of the first holding piece 23 and the tip edge of the first crimping piece 24 or in a position separated by a small gap. The space defined by the first plate body 22, the first holding piece 23, both side edges of the first crimping piece 24, and the auxiliary plate 40 functions as a storage section Q1 that stores the hanging bolt B. The height of this storage section Q1, that is, the height from the back surface of the first plate body 22 to the tip edges of the first holding piece 23 and the first crimping piece 24, is shorter than the diameter of the hanging bolt B. On the back surface of the first plate body 22, a plurality of first protrusions 22b that engage with the thread groove of the hanging bolt B stored in the storage section Q1 are distributed along the first holding piece 23.
第２支持体３０は第１支持体２０と同一の構造を有し、典型的には同じ部品で構成される。そのため、第２支持体３０の詳細説明は省略する。第１支持体２０と同様に、第２支持体３０は、第２支持体本体３１を有する。第２支持体本体３１は、第２板体３２、第２保持片３３、第２圧着片３４を有する。第２板体３２には締結ボルト５０が挿入される孔部３２ａが開けられ、その裏面には第２突起部３２ｂが設けられる。 The second support 30 has the same structure as the first support 20, and is typically composed of the same parts. Therefore, a detailed description of the second support 30 will be omitted. Like the first support 20, the second support 30 has a second support body 31. The second support body 31 has a second plate 32, a second holding piece 33, and a second crimping piece 34. The second plate 32 has a hole 32a into which the fastening bolt 50 is inserted, and a second protrusion 32b is provided on the back surface.
第１支持体２０と第２支持体３０とを同じ部品で構成することによって、コストを低減できるとともに、吊りボルト用支持具１０の取付作業において、どちらの部品を第１支持体２０としてもよいため、第１支持体２０と第２支持体３０とを取り違えたことによる取付作業のやり直しを回避することができ、作業性向上にも寄与する。なお、第２支持体３０は、第１支持体２０と同一部品ではなくてもよい。 By constructing the first support 20 and the second support 30 from the same part, costs can be reduced, and either part can be used as the first support 20 during the installation work of the suspension bolt support 10. This avoids the need to redo the installation work due to mistaking the first support 20 for the second support 30, which also contributes to improving workability. Note that the second support 30 does not have to be the same part as the first support 20.
本実施形態に係る吊りボルト用支持具１０の１つの特徴は、吊りボルトＢに対して吊りボルト用支持具１０を仮止めできる点にある。これを実現するために、吊りボルト用支持具１０は柔軟性を有する補助板４０を備える。 One feature of the suspension bolt support 10 according to this embodiment is that the suspension bolt support 10 can be temporarily fixed to the suspension bolt B. To achieve this, the suspension bolt support 10 is provided with a flexible auxiliary plate 40.
補助板４０は、弾性を有する透明樹脂製であり第１支持体２０よりも大きい円形板に構成される。補助板４０は締結ボルト５０が挿入される貫通孔を有する。少なくとも貫通孔の内周縁部分は、締結ボルト５０のネジ溝よりも薄く、この貫通孔の内周縁が締結ボルト５０のネジ溝に係合することにより、補助板４０は、締結ボルト５０に対して係止（螺合）される。 The auxiliary plate 40 is made of elastic transparent resin and is configured as a circular plate larger than the first support 20. The auxiliary plate 40 has a through hole into which the fastening bolt 50 is inserted. At least the inner peripheral edge of the through hole is thinner than the thread groove of the fastening bolt 50, and the inner peripheral edge of this through hole engages with the thread groove of the fastening bolt 50, thereby engaging (screwing) the auxiliary plate 40 with the fastening bolt 50.
収容部Ｑ１の高さは吊りボルトＢの直径よりも低く、収容部Ｑ１に収容された吊りボルトＢは、第１保持片２３及び第１圧着片２４の先端縁から収容部Ｑ１の外側に突出する。そのため、第１保持片２３及び第１圧着片２４の先端縁に当接する位置に配置された補助板４０は、吊りボルトＢによって、第１支持体２０から離れる方向に押圧される。上記のように締結ボルト５０に対して補助板４０が係止されていることで、補助板４０は、吊りボルトＢによって押圧されても、締結ボルト５０に沿って上下することはなく、吊りボルトＢの外周面に沿って湾曲する。このとき、補助板４０は、その弾性力によって、吊りボルトＢを第１支持体２０の裏面に押圧する。それにより、第１支持体２０の裏面に設けられた第１突起部２２ｂに吊りボルトＢのネジ溝が係合した状態を維持することができ、第１支持体２０を吊りボルトＢに仮止めできる。 The height of the accommodation section Q1 is lower than the diameter of the hanging bolt B, and the hanging bolt B accommodated in the accommodation section Q1 protrudes from the tip edge of the first holding piece 23 and the first crimping piece 24 to the outside of the accommodation section Q1. Therefore, the auxiliary plate 40 arranged at a position where it abuts against the tip edge of the first holding piece 23 and the first crimping piece 24 is pressed in a direction away from the first support 20 by the hanging bolt B. Since the auxiliary plate 40 is engaged with the fastening bolt 50 as described above, even if the auxiliary plate 40 is pressed by the hanging bolt B, it does not move up and down along the fastening bolt 50, but curves along the outer circumferential surface of the hanging bolt B. At this time, the auxiliary plate 40 presses the hanging bolt B against the back surface of the first support 20 by its elastic force. As a result, the state in which the thread groove of the hanging bolt B is engaged with the first protrusion 22b provided on the back surface of the first support 20 can be maintained, and the first support 20 can be temporarily fixed to the hanging bolt B.
なお、補助板４０は透明であるため、作業者は、吊りボルトＢに付された取付位置を示すマーカを確認しながら、吊りボルトＢに対して第１支持体２０を仮止めすることができる。これは、作業性向上に寄与する。また、第１支持体２０を吊りボルトＢに仮止めするという観点において、補助板４０は、少なくともその一部分が収容部Ｑ１を覆うことができる大きさを有すればよい。 In addition, because the auxiliary plate 40 is transparent, the worker can temporarily fasten the first support 20 to the hanging bolt B while checking the marker indicating the installation position attached to the hanging bolt B. This contributes to improving workability. In addition, from the viewpoint of temporarily fastening the first support 20 to the hanging bolt B, it is sufficient that the auxiliary plate 40 has a size that allows at least a portion of it to cover the storage section Q1.
補助板４０に目盛を表記しておくことで、作業者は、吊りボルトＢに対する振れ止めボルトＳの角度を一見してわかる。また、吊りボルトＢ用のガイド線と振れ止めボルトＳ用のガイド線とを補助板４０に予め表記してもよい。それにより、作業者はガイド線に沿って吊りボルトＢ，振れ止めボルトＳを配置すればよく、作業を効率的に行うことができる。 By marking the scale on the auxiliary plate 40, the worker can see at a glance the angle of the anti-sway bolt S relative to the hanging bolt B. Also, guide lines for the hanging bolt B and the anti-sway bolt S may be marked in advance on the auxiliary plate 40. This allows the worker to position the hanging bolt B and the anti-sway bolt S along the guide lines, allowing the worker to perform the work efficiently.
このように構成された吊りボルト用支持具１０は、図５乃至図８に示すように使用する。なお、図５、図６は吊りボルト用支持具１０を吊りボルトＢに仮止めした状態を示している。図７は吊りボルト用支持具１０に振れ止めボルトＳの取り付ける方法を説明するための補足説明図である。図８は吊りボルト用支持具１０を用いて吊りボルトＢに対して振れ止めボルトＳを固定した状態を示している。 The suspension bolt support 10 configured in this manner is used as shown in Figures 5 to 8. Figures 5 and 6 show the suspension bolt support 10 temporarily attached to the suspension bolt B. Figure 7 is a supplementary explanatory diagram for explaining the method of attaching the anti-sway bolt S to the suspension bolt support 10. Figure 8 shows the suspension bolt support 10 used to fix the anti-sway bolt S to the suspension bolt B.
典型的には、吊りボルト用支持具１０は、図２に示すような状態、すなわち、吊りボルト用支持具１０が組み立てられた状態であって、第１保持片２３及び第１圧着片２４の先端縁に補助板４０が当接した状態で使用される。作業者は、吊りボルトＢを第１保持片２３と補助板４０との間から挿入する。このとき、補助板４０は、第１保持片２３の先端縁よりも外側に向かって延設されているため、吊りボルトＢを第１保持片２３と補助板４０との間に案内するガイド板としても機能する。作業者は、吊りボルトＢを補助板４０に沿って第１保持片２３の先端縁まで移動させ、補助板４０と第１保持片２３の先端縁との間に押し込むことで、柔軟性を有する補助板４０は少し湾曲し、それにより補助板４０と第１保持片２３との間が押し広げられ、吊りボルトＢを収容部Ｑ１に収容することができる。 Typically, the suspension bolt support 10 is used in the state shown in FIG. 2, that is, in the state in which the suspension bolt support 10 is assembled and the auxiliary plate 40 is in contact with the leading edges of the first holding piece 23 and the first crimping piece 24. The worker inserts the suspension bolt B between the first holding piece 23 and the auxiliary plate 40. At this time, the auxiliary plate 40 extends outward from the leading edge of the first holding piece 23, so it also functions as a guide plate that guides the suspension bolt B between the first holding piece 23 and the auxiliary plate 40. The worker moves the suspension bolt B along the auxiliary plate 40 to the leading edge of the first holding piece 23 and pushes it between the leading edges of the auxiliary plate 40 and the first holding piece 23, causing the flexible auxiliary plate 40 to bend slightly, which causes the gap between the auxiliary plate 40 and the first holding piece 23 to be pushed wider, allowing the suspension bolt B to be accommodated in the accommodation section Q1.
図６に示すように、収容部Ｑ１に収容された吊りボルトＢの周面は第１板体２２、第１保持片２３、第１圧着片２４及び補助板４０によって四方から包囲される。それにより、吊りボルトＢに対する吊りボルト用支持具１０の吊りボルトＢの半径方向への移動を規制することができる。また、吊りボルトＢのネジ溝に第１突起部２２ｂを係合させることによって、吊りボルトＢに対する第１支持体２０の吊りボルトＢの軸方向への移動を規制することができる。吊りボルトＢのネジ溝と第１突起部２２ｂとの係合状態は、補助板４０により、第１支持体２０の裏面に設けられた第１突起部２２ｂをネジ溝に押圧することによって維持される。この補助板４０が第１支持体２０よりも大きいことで、吊りボルトＢに接触する接触面を広くすることができ、押圧する力を大きくすることができる。また、補助板４０を円形板に構成することで、第１支持体２０に対する補助板４０の向きを調整する作業が不要となるため、作業性を向上することができる。このように、吊りボルト用支持具１０の収容部Ｑ１に吊りボルトＢを収容するだけで、吊りボルトＢに対する吊りボルト用支持具１０の吊りボルトＢの軸方向及び外径方向への移動を規制することができ、吊りボルト用支持具１０を吊りボルトＢに仮止めすることができる。 As shown in FIG. 6, the circumferential surface of the hanging bolt B accommodated in the accommodation portion Q1 is surrounded on all sides by the first plate body 22, the first holding piece 23, the first crimping piece 24, and the auxiliary plate 40. This makes it possible to restrict the radial movement of the hanging bolt B of the hanging bolt support 10 relative to the hanging bolt B. In addition, by engaging the first protrusion 22b with the thread groove of the hanging bolt B, it is possible to restrict the axial movement of the hanging bolt B of the first support 20 relative to the hanging bolt B. The engagement state between the thread groove of the hanging bolt B and the first protrusion 22b is maintained by the auxiliary plate 40 pressing the first protrusion 22b provided on the back surface of the first support 20 against the thread groove. Since the auxiliary plate 40 is larger than the first support 20, the contact surface in contact with the hanging bolt B can be made wider, and the pressing force can be increased. In addition, by configuring the auxiliary plate 40 as a circular plate, the task of adjusting the orientation of the auxiliary plate 40 relative to the first support 20 is not required, improving workability. In this way, simply by storing the hanging bolt B in the storage portion Q1 of the hanging bolt support 10, the axial and radial movement of the hanging bolt B of the hanging bolt support 10 relative to the hanging bolt B can be restricted, and the hanging bolt support 10 can be temporarily fixed to the hanging bolt B.
仮止めした状態は、締結ボルト５０に係止された補助板４０を緩める（第１支持体２０から離れる方向に移動させる）、吊りボルトＢを押圧している補助板４０の箇所を指で広げる、吊りボルト用支持具１０を、第１支持体２０を吊りボルトＢから離れる方向に移動させる、などの作業者による簡単な操作で解除することができる。例えば、吊りボルト用支持具１０の位置を調整したいとき、作業者は、吊りボルト用支持具１０を、第１支持体２０が吊りボルトＢから離反する方向に引きながら、吊りボルトＢの軸方向に沿って上下に移動させることができる。この移動操作は、片手でもできる簡単な操作であり、作業者による作業性を向上させる。 The temporary fastening state can be released by a simple operation by the worker, such as loosening the auxiliary plate 40 engaged with the fastening bolt 50 (moving it in a direction away from the first support 20), spreading the part of the auxiliary plate 40 pressing against the hanging bolt B with the fingers, or moving the hanging bolt support 10 in a direction away from the hanging bolt B. For example, when it is desired to adjust the position of the hanging bolt support 10, the worker can move the hanging bolt support 10 up and down along the axial direction of the hanging bolt B while pulling the first support 20 in a direction away from the hanging bolt B. This moving operation is a simple operation that can be performed with one hand, improving the ease of operation by the worker.
なお、上記の仮止め作業手順は、補助板４０が柔軟性を有することが前提となる。しかしながら、吊りボルト用支持具１０を吊りボルトＢに仮止めするという観点では、補助板４０は必ずしも柔軟性を有さなくてもよい。以下、硬質樹脂または金属で形成された柔軟性を有さない補助板４０を備える吊りボルト用支持具１０を使用したときの仮止め作業手順について説明する。 The above temporary fastening procedure is premised on the premise that the auxiliary plate 40 is flexible. However, from the viewpoint of temporarily fastening the suspension bolt support 10 to the suspension bolt B, the auxiliary plate 40 does not necessarily have to be flexible. Below, the temporary fastening procedure when using a suspension bolt support 10 equipped with an inflexible auxiliary plate 40 made of hard resin or metal is described.
吊りボルト用支持具１０は、図２に示すような状態、すなわち、補助板４０が第１保持片２３及び第１圧着片２４の先端縁に当接した状態ではなく、補助板４０が第１保持片２３及び第１圧着片２４の先端縁から吊りボルトＢの直径以上の距離を隔てた位置に配置された状態で使用される。作業者は、吊りボルトＢを第１保持片２３の先端縁と補助板４０との間の隙間から挿入し、第１板体２２、第１保持片２３及び第１圧着片２４の両側縁で規定される溝内に収容する。溝内に収容された吊りボルトＢのネジ溝に第１突起部２２ｂは係合される。次に、締結ボルト５０に沿って補助板４０を移動させ、吊りボルトＢに当接させる。それにより、補助板４０が柔軟性を有さなくても、少なくとも締結ボルト５０のネジ溝に第１突起部２２ｂを係合させた状態を維持することができる。それにより、吊りボルトＢに対する吊りボルト用支持具１０の吊りボルトＢの軸方向及び外径方向への移動を規制することができ、吊りボルト用支持具１０を吊りボルトＢに仮止めすることができる。 The suspension bolt support 10 is used in a state as shown in FIG. 2, that is, in a state where the auxiliary plate 40 is not in contact with the leading edges of the first retaining piece 23 and the first crimping piece 24, but in a state where the auxiliary plate 40 is disposed at a position spaced apart from the leading edges of the first retaining piece 23 and the first crimping piece 24 by a distance equal to or greater than the diameter of the suspension bolt B. The worker inserts the suspension bolt B from the gap between the leading edge of the first retaining piece 23 and the auxiliary plate 40, and places it in a groove defined by both side edges of the first plate body 22, the first retaining piece 23, and the first crimping piece 24. The first protrusion 22b is engaged with the thread groove of the suspension bolt B housed in the groove. Next, the auxiliary plate 40 is moved along the fastening bolt 50 and brought into contact with the suspension bolt B. As a result, even if the auxiliary plate 40 does not have flexibility, it is possible to maintain at least the state in which the first protrusion 22b is engaged with the thread groove of the fastening bolt 50. This makes it possible to restrict the movement of the suspension bolt support 10 relative to the suspension bolt B in the axial and radial directions of the suspension bolt B, and to temporarily secure the suspension bolt support 10 to the suspension bolt B.
吊りボルトBに吊りボルト用支持具１０を仮止めした後の作業は以下の通りである。すなわち、図７に示すように、作業者は、振れ止めボルトＳを補助板４０と第２保持片３３及び第２圧着片３４の先端縁との間から第２支持体３０の収容部Ｑ２に収容し、ナット６０を仮締めする。ここでの仮締めとは、収容部Ｑ２に収容された振れ止めボルトＳのネジ溝と第２突起部３２ｂとの係合状態を維持できる程度にナット６０を締めることをいう。 After the suspension bolt support 10 is temporarily attached to the suspension bolt B, the work is as follows. That is, as shown in FIG. 7, the worker places the anti-sway bolt S in the accommodation portion Q2 of the second support 30 from between the auxiliary plate 40 and the leading edge of the second holding piece 33 and the second crimping piece 34, and temporarily tightens the nut 60. "Temporarily tightening" here means tightening the nut 60 to an extent that the engagement state between the thread groove of the anti-sway bolt S accommodated in the accommodation portion Q2 and the second protrusion portion 32b can be maintained.
ナット６０を仮締めした状態で、第２支持体３０から振れ止めボルトＳが脱落することはなく、第２支持体３０に対して振れ止めボルトＳは仮止めすることができる。作業者は、第２支持体３０を手に持ち、吊りボルトＢに対する振れ止めボルトＳの角度を調整した後、ナット６０を本締めする。ナット６０を本締めすることで、図８に示すように、第１支持体２０と第２支持体３０との間に吊りボルトＢ及び振れ止めボルトＳを挟み込み、固定することができる。このときの固定力は、第１支持体２０と第２支持体３０とに挟まれた吊りボルトＢ及び振れ止めボルトＳが互いに圧着されるだけではなく、保持片２３，３３及び圧着片２４，３４も作用して、全体が互いに圧着されるため、非常に強い。 With the nut 60 temporarily fastened, the anti-sway bolt S will not fall off the second support 30, and the anti-sway bolt S can be temporarily fastened to the second support 30. The worker holds the second support 30 in his/her hand, adjusts the angle of the anti-sway bolt S relative to the hanging bolt B, and then fully fastens the nut 60. By fully fastening the nut 60, the hanging bolt B and the anti-sway bolt S can be sandwiched and fixed between the first support 20 and the second support 30, as shown in FIG. 8. The fixing force at this time is very strong because not only the hanging bolt B and the anti-sway bolt S sandwiched between the first support 20 and the second support 30 are pressed against each other, but also the holding pieces 23, 33 and the pressing pieces 24, 34 act to press the entire parts against each other.
以上説明した吊りボルト用支持具１０によれば、補助板４０があることで、吊りボルト用支持具１０を吊りボルトＢに対して仮止めすることができる。この仮止めを実現する構成は非常に簡単なものであって、製造コストも低廉である。また、吊りボルトＢに対して簡単な操作で仮止めできるため、仮止めに際して、不安定な脚立や梯子の上で危険、且つ複雑な作業を行う必要が無く、作業を安全に行うことができる。 According to the suspension bolt support 10 described above, the auxiliary plate 40 allows the suspension bolt support 10 to be temporarily fixed to the suspension bolt B. The configuration that realizes this temporary fixing is very simple, and the manufacturing cost is also low. In addition, since the suspension bolt B can be temporarily fixed with a simple operation, there is no need to perform dangerous and complicated work on an unstable stepladder or ladder when temporarily fixing, and the work can be performed safely.
本実施形態に係る吊りボルト用支持具１０は、吊りボルトＢに仮止めすることができることを１つの特徴としている。したがって、吊りボルト用支持具１０を用いて吊りボルトＢに対して固定する対象は振れ止めボルトＳに限定されない。吊りボルトＢに対して固定する対象は、全ネジボルト、丸鋼、角鋼等の棒状材とすることができる。 One of the features of the suspension bolt support 10 according to this embodiment is that it can be temporarily fixed to the suspension bolt B. Therefore, the object to be fixed to the suspension bolt B using the suspension bolt support 10 is not limited to the anti-vibration bolt S. The object to be fixed to the suspension bolt B can be a rod-shaped material such as a fully threaded bolt, round bar, or square bar.
なお、本実施形態に係る吊りボルト用支持具１０において、補助板４０は締結ボルト５０に挿入されていたが、第１支持体２０の溝内に収容された吊りボルトＢのネジ溝と第１支持体２０の裏面の第１突起部２２ｂとの係合状態を維持できるのであれば、補助板４０が取り付けられる位置はこれに限定されない。例えば、補助板４０は、第１支持体２０、例えば第１圧着片２４の内面、第１圧着片２４の先端縁、または第１板体２２の裏面などに取り付ける構成とすることができる。締結ボルト５０に補助板４０を挿入する構成は、上記の構成に比べて組立工数が少ないため、製造コストの低下が期待できる。また、何らかの要因で、作業前に補助板４０が破損した場合であっても、補助板４０だけを交換すればよく、使いやすい。 In the hanging bolt support 10 according to the present embodiment, the auxiliary plate 40 is inserted into the fastening bolt 50, but as long as the engagement between the thread groove of the hanging bolt B housed in the groove of the first support 20 and the first protrusion 22b on the back surface of the first support 20 can be maintained, the position at which the auxiliary plate 40 is attached is not limited to this. For example, the auxiliary plate 40 can be attached to the first support 20, for example, the inner surface of the first crimping piece 24, the tip edge of the first crimping piece 24, or the back surface of the first plate body 22. The configuration in which the auxiliary plate 40 is inserted into the fastening bolt 50 requires fewer assembly steps than the above configuration, so that a reduction in manufacturing costs can be expected. In addition, even if the auxiliary plate 40 is damaged before work due to some factor, only the auxiliary plate 40 needs to be replaced, making it easy to use.
また、本実施形態に係る吊りボルト用支持具１０において、柔軟性を有する補助板４０は、吊りボルトＢのネジ溝と第１支持体２０の第１突起部２２ｂとの係合状態を維持するために吊りボルトＢのネジ溝に第１突起部２２ｂを押し付ける押圧部材として機能していた。柔軟性を有する補助板４０によって、第１支持体２０を吊りボルトＢに対して押圧するだけで、吊りボルト用支持具１０を吊りボルトＢに仮止めできるのであれば、吊りボルト用支持具１０は第１突起部２２ｂを有さなくてもよい。さらに、押圧によって仮止めできるのであれば、本実施形態に係る吊りボルト用支持具は、ネジ溝が形成されていない丸鋼、角鋼等の棒状材に仮止めすることができる棒状材用支持具として使用することができる。なお、補助板４０が柔軟性を有さない場合であっても、例えば締結ボルト５０に補助板４０を螺合させ、補助板４０を締めることで、棒状材を第１支持体２０に向かって押圧するようにしてもよい。 In addition, in the suspension bolt support 10 according to this embodiment, the flexible auxiliary plate 40 functions as a pressing member that presses the first protrusion 22b against the thread groove of the suspension bolt B to maintain the engagement between the thread groove of the suspension bolt B and the first protrusion 22b of the first support 20. If the suspension bolt support 10 can be temporarily fixed to the suspension bolt B by simply pressing the first support 20 against the suspension bolt B with the flexible auxiliary plate 40, the suspension bolt support 10 does not need to have the first protrusion 22b. Furthermore, if temporary fixing can be achieved by pressing, the suspension bolt support according to this embodiment can be used as a rod-shaped material support that can be temporarily fixed to rod-shaped materials such as round steel and square steel that do not have a thread groove. Even if the auxiliary plate 40 does not have flexibility, the rod-shaped material may be pressed toward the first support 20 by, for example, screwing the auxiliary plate 40 onto the fastening bolt 50 and tightening the auxiliary plate 40.
また、本実施形態に係る吊りボルト用支持具１０は、吊りボルトＢに対して複数本の全ネジボルト（棒状材）を固定する用途に使用することができる。例えば、吊りボルトＢに対して互いに異なる方向に沿って配置された２本の全ネジボルトを固定する用途として使用する場合には、吊りボルト用支持具１０は、さらに第２支持体３０を挟んで第１支持体２０の反対側に配置される第３支持体を有すればよい。このように、吊りボルト用支持具は、吊りボルトに対して固定する棒状材の本数に応じた数の支持体を有すればよい。 The suspension bolt support 10 according to this embodiment can be used to secure multiple fully threaded bolts (rod-shaped materials) to the suspension bolt B. For example, when used to secure two fully threaded bolts arranged in different directions to the suspension bolt B, the suspension bolt support 10 may further include a third support arranged on the opposite side of the first support 20 across the second support 30. In this way, the suspension bolt support may include a number of supports corresponding to the number of rod-shaped materials to be secured to the suspension bolt.
