Description

本発明は、３本のボルトを連結するボルト連結具に関する。 The present invention relates to a bolt connector for connecting three bolts.

例えば空調機器の室内機や、照明機器、ケーブルラック等の吊設機器は、吊ボルトを用いて天井スラブ等の構造体から吊設される場合がある。このような場合において、地震等に起因する吊設機器の揺れ動きを抑制するため、吊ボルトから、その両隣に位置する他の吊ボルトに対して交差姿勢で振止ボルトを配設し、これらを相互に連結して補強する場合がある。この場合、吊ボルトと２本の振止ボルトとを連結するボルト連結具が用いられる。 For example, an indoor unit of an air conditioner, a lighting device, and a suspended device such as a cable rack may be suspended from a structure such as a ceiling slab using a suspension bolt. In such a case, in order to suppress the swinging movement of the suspended equipment caused by an earthquake or the like, the suspension bolts are arranged in a crossing posture with respect to the other suspension bolts located on both sides of the suspension bolt, In some cases, they may be connected to each other for reinforcement. In this case, a bolt connector that connects the suspension bolt and the two bracing bolts is used.

このようなボルト連結具の一例が、例えば特許第６００９７１０号公報（特許文献１）に開示されている。特許文献１のボルト連結具は、ベース部材〔狭着体１〕と、２つの狭着部材〔斜め支持体３〕と、ベース部材に対して狭着部材をそれぞれ固定する２本の連結ボルト〔連結ボルト２〕とを備えている。そして、狭着部材とベース部材とを重ねて連結ボルトで連結することで、その連結ボルトを中心に振止ボルト〔長ボルトＱ〕の角度を調整自在にするとともに、当該振止ボルトを狭着部材でベース部材に圧着固定している。これにより、吊ボルトの振れ止めを容易に行うことができると特許文献１では謳われている。 An example of such a bolt connector is disclosed in, for example, Japanese Patent No. 6009710 (Patent Document 1). The bolt connector of Patent Document 1 includes a base member [narrow body 1], two narrow members [diagonal support body 3], and two connection bolts that respectively fix the narrow member to the base member [ Connecting bolt 2]. Then, the narrowing member and the base member are overlapped and connected with a connecting bolt so that the angle of the anti-vibration bolt (long bolt Q) can be adjusted around the connecting bolt and the anti-locking bolt is tightly attached. The member is crimped and fixed to the base member. In this way, Patent Document 1 claims that the suspension bolts can be easily prevented from swinging.

また、特許文献１のボルト連結具では、２本の連結ボルトのそれぞれに弾性部材〔コイルスプリング４〕が装着されており、この弾性部材は、ベース部材を構成する第一ベース部材〔外側狭着体１Ａ〕と第二ベース部材〔内側狭着体１Ｂ〕とを互いに圧接付勢している。これにより、吊ボルトに対して２部材からなるベース部材を容易に仮止めすることが可能となっている。 Further, in the bolt connector disclosed in Patent Document 1, an elastic member [coil spring 4] is mounted on each of the two connecting bolts, and this elastic member is a first base member [outside constriction that constitutes the base member. The body 1A] and the second base member [inner narrow body 1B] are pressed against each other. Thereby, the base member consisting of two members can be easily temporarily fixed to the suspension bolt.

しかし、特許文献１の弾性部材は、逆に、２つの狭着部材をベース部材から離間させるように付勢するので、ベース部材と狭着部材との間に振止ボルトを狭着固定する際には、作業者は振止ボルトをしっかりと支えながら作業を行う必要がある。このため、取付作業に手間取る可能性があり、また、そのような取付作業が高所で行われる場合には、その作業がより困難なものになる虞があった。 However, the elastic member of Patent Document 1 conversely biases the two narrowing members away from the base member, so that when the anchor bolt is tightly fixed between the base member and the narrowing member, Therefore, the operator needs to work while firmly supporting the swing bolt. For this reason, there is a possibility that it takes time for the mounting work, and when such mounting work is performed at a high place, there is a possibility that the work becomes more difficult.

第二ベース部材４０は、第一ベース部材３０のおよそ半分の大きさの帯板状部材で構成されている。本実施形態では、第二ベース部材４０は、第一ベース部材３０に対して第一狭着部材５と同じ側に配置されている。第二ベース部材４０は、第一取付部３１に重ね合わされる平板状の重合部４１と、この重合部４１から連続して延びる湾曲部４２とを有する。重合部４１は、第一ベース部材３０の第一取付部３１よりも若干大きく形成されている。重合部４１は、第一連結ボルト７が挿通されるボルト挿通孔４３を有する。また、第二ベース部材４０は、重合部４１の上下それぞれの辺縁に沿って延びる補強リブ４５を有する。補強リブ４５は、重合部４１と第一ベース部材３０の第一取付部３１とが重ね合わされた状態で、辺縁切欠部３７に配置される。 The second base member 40 is configured by a band plate-like member that is approximately half the size of the first base member 30. In the present embodiment, the second base member 40 is disposed on the same side as the first narrowing member 5 with respect to the first base member 30. The second base member 40 includes a flat plate-like overlapping portion 41 that is superimposed on the first attachment portion 31, and a curved portion 42 that extends continuously from the overlapping portion 41. The overlapping portion 41 is formed slightly larger than the first attachment portion 31 of the first base member 30. The overlapping portion 41 has a bolt insertion hole 43 through which the first connection bolt 7 is inserted. Further, the second base member 40 has reinforcing ribs 45 extending along the upper and lower edges of the overlapping portion 41. The reinforcing rib 45 is disposed in the edge cutout portion 37 in a state where the overlapping portion 41 and the first attachment portion 31 of the first base member 30 are overlapped.

湾曲部４２は、重合部４１が第一取付部３１に重ね合わされた状態で、第一ベース部材３０の湾曲部３３に対面するように延出している（図４を参照）。湾曲部４２は、平面視形状がおよそ９０°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４２は、吊ボルトＰの外面に概ね沿うように湾曲している。湾曲部４２の内面に、第一ベース部材３０の湾曲部３３の係止突起３３Ａと同様の係止突起が突出形成されても良い。 The bending portion 42 extends so as to face the bending portion 33 of the first base member 30 in a state where the overlapping portion 41 is overlapped with the first attachment portion 31 (see FIG. 4). The curved portion 42 is formed as a curved plate portion having a circular shape with a central angle of about 90 ° in plan view. The curved portion 42 is curved so as to substantially follow the outer surface of the suspension bolt P. A locking projection similar to the locking projection 33 </ b> A of the bending portion 33 of the first base member 30 may be formed on the inner surface of the bending portion 42.

図３及び図４に示すように、第一ベース部材３０と第二ベース部材４０とは、ベース部材３に第一狭着部材５を取り付けるための第一連結ボルト７を利用して吊ボルトＰを狭着固定する（一体化状態となる）ように構成されている。なお、ベース部材３に第二狭着部材６を取り付けるための第二連結ボルト８は、吊ボルトＰを狭着固定する（一体化状態となる）ためには寄与しない。すなわち、本実施形態のボルト連結具１は、第一連結ボルト７及び第二連結ボルト８のうちの第一連結ボルト７だけの締結によって第一ベース部材３０と第二ベース部材４０とが一体化状態となるように構成されている。さらに本実施形態では、第一取付部３１と重合部４１とが重ね合わされた状態で第一連結ボルト７を締結することにより、第一ベース部材３０と第二ベース部材４０とが一体化状態となるように構成されている。 As shown in FIGS. 3 and 4, the first base member 30 and the second base member 40 use the first connecting bolt 7 for attaching the first narrowing member 5 to the base member 3, and the suspension bolt P Is fixed tightly (becomes an integrated state). The second connecting bolt 8 for attaching the second narrowing member 6 to the base member 3 does not contribute to tightly fixing the suspension bolt P (becomes an integrated state). That is, in the bolt connector 1 of this embodiment, the first base member 30 and the second base member 40 are integrated by fastening only the first connecting bolt 7 of the first connecting bolt 7 and the second connecting bolt 8. It is comprised so that it may be in a state. Furthermore, in this embodiment, the 1st base member 30 and the 2nd base member 40 are made into an integrated state by fastening the 1st connection bolt 7 in the state with which the 1st attaching part 31 and the superposition | polymerization part 41 were piled up. It is comprised so that it may become.

第一狭着部材５及び第二狭着部材６は、ベース部材３の両端部に固定されてそれぞれ振止ボルトＱを狭着固定する。第一狭着部材５は、ベース部材３（本例では第一取付部３１と重なっている重合部４１）に対向するベース対向部５１と、ベース対向部５１から連続して延びる湾曲部５３とを有する。ベース対向部５１は、平板状に形成され、ベース部材３に直接対向するように配置されている。ベース対向部５１には、第一連結ボルト７が挿通されるボルト挿通孔５２が形成されている。 The first narrowing member 5 and the second narrowing member 6 are fixed to both end portions of the base member 3 so as to tightly fix the swing bolts Q, respectively. The first narrowing member 5 includes a base facing portion 51 that faces the base member 3 (in this example, the overlapping portion 41 that overlaps the first mounting portion 31), and a curved portion 53 that extends continuously from the base facing portion 51. Have The base facing portion 51 is formed in a flat plate shape and is disposed so as to directly face the base member 3. A bolt insertion hole 52 through which the first connection bolt 7 is inserted is formed in the base facing portion 51.

湾曲部５３は、第一振止ボルトＱ１の外面に概ね沿う半円筒状に形成されている。湾曲部５３の内面には、第一振止ボルトＱ１のネジ部に係止される係止突起（図示せず）が突出形成されていることが好ましい。また、第一狭着部材５は、湾曲部５３の軸方向の両端部に補強リブ５４を有する。 The curved portion 53 is formed in a semi-cylindrical shape generally along the outer surface of the first anti-vibration bolt Q1. It is preferable that a locking projection (not shown) that is locked to the threaded portion of the first anti-vibration bolt Q1 is formed on the inner surface of the curved portion 53 so as to protrude. Further, the first narrowing member 5 has reinforcing ribs 54 at both ends in the axial direction of the bending portion 53.

第一狭着部材５は、ベース対向部５１からベース部材３とは反対側に離間して配置される離間配置部５５をさらに有している。離間配置部５５は、ベース部材３及びベース対向部５１と平行に配置されている。離間配置部５５は、第一連結ボルト７が挿通されるボルト挿通孔５６を有する。本実施形態では、ボルト挿通孔５６が、第一狭着部材５の離間配置部５５に形成された「孔部」に相当する。この離間配置部５５のボルト挿通孔５６は、ベース対向部５１のボルト挿通孔５２よりも大径に形成されている。ベース対向部５１のボルト挿通孔５２は第一連結ボルト７の軸部７２よりも大径でかつ弾性部材９よりも小径であるのに対して、離間配置部５５のボルト挿通孔５６は弾性部材９よりも大径となっている。このため、図４に示すように、第一連結ボルト７に装着される弾性部材９は、離間配置部５５を貫通して、ベース対向部５１と第一連結ボルト７の頭部７１との間に配置されている。ベース対向部５１と離間配置部５５との間の空間は、弾性部材９が収容される弾性部材収容空間Ａとなっている。 The first narrowing member 5 further includes a spaced-apart portion 55 that is spaced apart from the base facing portion 51 on the side opposite to the base member 3. The spaced-apart arrangement portion 55 is arranged in parallel with the base member 3 and the base facing portion 51. The spaced-apart arrangement portion 55 has a bolt insertion hole 56 through which the first connection bolt 7 is inserted. In the present embodiment, the bolt insertion hole 56 corresponds to a “hole” formed in the spaced-apart arrangement portion 55 of the first narrowing member 5. The bolt insertion hole 56 of the spaced-apart arrangement portion 55 is formed to have a larger diameter than the bolt insertion hole 52 of the base facing portion 51. The bolt insertion hole 52 of the base facing portion 51 is larger in diameter than the shaft portion 72 of the first connection bolt 7 and smaller in diameter than the elastic member 9, whereas the bolt insertion hole 56 of the spaced-apart arrangement portion 55 is an elastic member. The diameter is larger than 9. For this reason, as shown in FIG. 4, the elastic member 9 attached to the first connection bolt 7 passes through the spaced-apart portion 55 and is between the base facing portion 51 and the head 71 of the first connection bolt 7. Is arranged. A space between the base facing portion 51 and the spaced apart portion 55 is an elastic member accommodation space A in which the elastic member 9 is accommodated.

第二狭着部材６は、第一狭着部材５と同様の構成を備えている。すなわち、第二狭着部材６は、ベース部材３に対向するベース対向部６１と、第二振止ボルトＱ２の外面に概ね沿う湾曲部６３と、ベース対向部６１からベース部材３とは反対側に離間して配置される離間配置部６５とを有する。離間配置部６５のボルト挿通孔６６は、ベース対向部６１のボルト挿通孔６２よりも大径に形成されている。本実施形態では、ボルト挿通孔６６が、第二狭着部材６の離間配置部６５に形成された「孔部」に相当する。第二連結ボルト８の軸部８２に装着される弾性部材９は、離間配置部６５を貫通して、ベース対向部６１と第二連結ボルト８の頭部８１との間に配置されている。ベース対向部６１と離間配置部６５との間の空間は、第二連結ボルト８に装着される弾性部材９が収容される弾性部材収容空間Ａとなっている。 The second narrowing member 6 has the same configuration as the first narrowing member 5. That is, the second narrowing member 6 includes a base facing portion 61 that faces the base member 3, a curved portion 63 that is generally along the outer surface of the second rocking bolt Q 2, and the base facing portion 61 that is opposite to the base member 3. And a spaced-apart portion 65 that is spaced apart from each other. The bolt insertion hole 66 of the spaced-apart arrangement portion 65 is formed with a larger diameter than the bolt insertion hole 62 of the base facing portion 61. In the present embodiment, the bolt insertion hole 66 corresponds to a “hole” formed in the spaced-apart arrangement portion 65 of the second narrowing member 6. The elastic member 9 attached to the shaft portion 82 of the second connection bolt 8 passes through the spaced-apart arrangement portion 65 and is disposed between the base facing portion 61 and the head 81 of the second connection bolt 8. A space between the base facing portion 61 and the spaced-apart arrangement portion 65 is an elastic member accommodation space A in which the elastic member 9 attached to the second connecting bolt 8 is accommodated.

第一連結ボルト７は、第一狭着部材５を貫通して、ベース部材３（本例では第一取付部３１と重なっている重合部４１）に第一狭着部材５を取り付ける。その際、第一狭着部材５の湾曲部５３に第一振止ボルトＱ１が収容された状態で、第一連結ボルト７の締結によってベース部材３と第一狭着部材５との間に第一振止ボルトＱ１が狭着固定される。こうして、第一狭着部材５は、第一連結ボルト７により、ベース部材３に対して相対変位可能に連結され、かつ、ベース部材３との間に第一振止ボルトＱ１を挟み込んで保持する。このような構成では、第一連結ボルト７を中心に第一振止ボルトＱ１の角度が調整自在であるとともに、第一連結ボルト７の締結によって第一振止ボルトＱ１が第一狭着部材５でベース部材３に圧着固定される。 The first connecting bolt 7 passes through the first narrowing member 5 and attaches the first narrowing member 5 to the base member 3 (in this example, the overlapping portion 41 overlapping the first mounting portion 31). At that time, in a state where the first rocking bolt Q1 is accommodated in the curved portion 53 of the first narrowing member 5, the first connecting bolt 7 is fastened between the base member 3 and the first narrowing member 5. One swing bolt Q1 is fixed tightly. Thus, the first narrowing member 5 is connected to the base member 3 by the first connecting bolt 7 so as to be relatively displaceable, and the first locking bolt Q1 is sandwiched and held between the first narrowing member 5 and the base member 3. . In such a configuration, the angle of the first anti-vibration bolt Q1 can be adjusted around the first connection bolt 7 and the first anti-vibration bolt Q1 can be adjusted by fastening the first connection bolt 7. Thus, the base member 3 is crimped and fixed.

また、第一連結ボルト７は、第二ベース部材４０を貫通するとともに第一狭着部材５を介して、第一ベース部材３０と第二ベース部材４０とを一体化させる。第一連結ボルト７は、第一狭着部材５及び第二ベース部材４０を貫通し、第一ベース部材３０の第一取付部３１に形成されたバーリングタップ部３４の雌ネジに螺合する。こうして、第一連結ボルト７の締結によって第一ベース部材３０と第二ベース部材４０とが一体化状態となり、この一体化状態で、第一ベース部材３０の湾曲部３３と第二ベース部材４０の湾曲部４２との間に吊ボルトＰが狭着固定される。 The first connecting bolt 7 penetrates the second base member 40 and integrates the first base member 30 and the second base member 40 through the first narrowing member 5. The first connecting bolt 7 passes through the first narrowing member 5 and the second base member 40 and is screwed into a female screw of a burring tap portion 34 formed in the first attachment portion 31 of the first base member 30. Thus, the first base member 30 and the second base member 40 are integrated with each other by fastening the first connecting bolt 7. In this integrated state, the bending portion 33 of the first base member 30 and the second base member 40 are integrated. The suspension bolt P is fixed tightly between the curved portion 42.

第二連結ボルト８は、第二狭着部材６を貫通して、ベース部材３（本例では第一ベース部材３０の第二取付部３２）に第二狭着部材６を取り付ける。第二連結ボルト８は、第二狭着部材６を貫通し、第二取付部３２に形成されたバーリングタップ部３５の雌ネジに螺合する。そして、第二狭着部材６の湾曲部６３に第二振止ボルトＱ２が収容された状態で、第二連結ボルト８の締結によってベース部材３と第二狭着部材６との間に第二振止ボルトＱ２が狭着固定される。こうして、第二狭着部材６は、第二連結ボルト８により、ベース部材３に対して相対変位可能に連結され、かつ、ベース部材３との間に第二振止ボルトＱ２を挟み込んで保持する。このような構成では、第二連結ボルト８を中心に第二振止ボルトＱ２の角度が調整自在であるとともに、第二連結ボルト８の締結によって第二振止ボルトＱ２が第二狭着部材６でベース部材３に圧着固定される。 The second connecting bolt 8 passes through the second narrowing member 6 and attaches the second narrowing member 6 to the base member 3 (the second mounting portion 32 of the first base member 30 in this example). The second connecting bolt 8 passes through the second narrowing member 6 and is screwed into the female screw of the burring tap portion 35 formed in the second mounting portion 32. Then, in a state in which the second anti-vibration bolt Q2 is accommodated in the curved portion 63 of the second narrowing member 6, the second connecting bolt 8 is fastened between the base member 3 and the second narrowing member 6. The brace bolt Q2 is fixed tightly. In this way, the second narrowing member 6 is connected to the base member 3 by the second connecting bolt 8 so as to be relatively displaceable, and the second anchoring bolt Q2 is sandwiched and held between the second narrowing member 6 and the base member 3. . In such a configuration, the angle of the second rocking bolt Q2 can be adjusted around the second connecting bolt 8, and the second rocking bolt Q2 is fastened to the second narrowing member 6 by fastening the second connecting bolt 8. Thus, the base member 3 is crimped and fixed.

なお、第二連結ボルト８は、第二狭着部材６をベース部材３に取り付けるだけであり、第一連結ボルト７とは異なり、上述したように第一ベース部材３０と第二ベース部材４０とを一体化させるためには寄与しない。 The second connecting bolt 8 only attaches the second narrowing member 6 to the base member 3, and unlike the first connecting bolt 7, the first base member 30 and the second base member 40, as described above. Does not contribute to the integration.

本実施形態のボルト連結具１は、ベース部材３（第一ベース部材３０及び第二ベース部材４０）、第一狭着部材５、第二狭着部材６、第一連結ボルト７、第二連結ボルト８、及び弾性部材９の全てが仮組された状態（仮組状態）で施工することができる。図５に示すように、弾性部材９が装着された第二連結ボルト８を第二狭着部材６を貫通させて第一ベース部材３０に緩止めするとともに、弾性部材９が装着された第一連結ボルト７を第一狭着部材５及び第二ベース部材４０を貫通させて第一ベース部材３０に緩止めする。この仮組状態では、第一ベース部材３０と第二ベース部材４０とは、第一連結ボルト７により、吊ボルトＰの配置予定位置である湾曲部３３，４２どうしの間の空間に対して、ベース部材３の延在方向の一方側でのみ係止された状態となっている。なお、ベース部材３の延在方向は、本実施形態では、第一ベース部材３０における第一取付部３１から湾曲部３３を経て第二取付部３２へと向かう方向である。 The bolt connector 1 of the present embodiment includes a base member 3 (first base member 30 and second base member 40), a first narrowing member 5, a second narrowing member 6, a first coupling bolt 7, and a second coupling. The bolt 8 and the elastic member 9 can all be temporarily assembled (temporarily assembled). As shown in FIG. 5, the second connecting bolt 8 to which the elastic member 9 is attached passes through the second narrowing member 6 and is loosely locked to the first base member 30, and the first to which the elastic member 9 is attached. The connecting bolt 7 passes through the first narrowing member 5 and the second base member 40 and is loosely locked to the first base member 30. In this temporarily assembled state, the first base member 30 and the second base member 40 are moved by the first connecting bolt 7 with respect to the space between the curved portions 33 and 42 that are the planned placement positions of the suspension bolt P. The base member 3 is locked only on one side in the extending direction. In this embodiment, the extending direction of the base member 3 is a direction from the first mounting portion 31 of the first base member 30 toward the second mounting portion 32 via the curved portion 33.

この仮組状態で、第一連結ボルト７側の弾性部材９を圧縮変形するように押圧して、第一ベース部材３０と第二ベース部材４０とを拡開させる（図５を参照）。そして、それにより生じる隙間Ｇを通って、第一ベース部材３０と第二ベース部材４０との間に吊ボルトＰを径方向にスライド移動させて挿入させる（※実際にはボルト連結具１側を動かして上記のように相対移動させる）。 In this temporarily assembled state, the first base member 30 and the second base member 40 are expanded by pressing the elastic member 9 on the first connecting bolt 7 side so as to be compressed and deformed (see FIG. 5). Then, through the gap G generated thereby, the suspension bolt P is slid in the radial direction and inserted between the first base member 30 and the second base member 40 (in practice, the bolt connector 1 side is inserted). And move it relative as above).

その後、弾性部材９に対する外部からの押圧を解除すると、図６に示すように、第一連結ボルト７に装着されている弾性部材９は、ベース部材３に対して第一狭着部材５を圧接付勢し、ベース部材３と第一狭着部材５との間に第一振止ボルトＱ１を挟んで仮止めする。合わせて、弾性部材９は、第一ベース部材３０と第二ベース部材４０とを圧接付勢し、吊ボルトＰを挟み込む状態で第一ベース部材３０と第二ベース部材４０とを仮止めする。また、第二連結ボルト８に装着されている弾性部材９は、ベース部材３に対して第二狭着部材６を圧接付勢し、ベース部材３と第二狭着部材６との間に第二振止ボルトＱ２を挟んで仮止めする。このようにして、吊ボルトＰに対するベース部材３の仮止めと、ベース部材３に対する２本の振止ボルトＱの仮止めとを同時に行うことができる。 Thereafter, when the external pressure on the elastic member 9 is released, as shown in FIG. 6, the elastic member 9 attached to the first connecting bolt 7 presses the first narrowing member 5 against the base member 3. The first biasing bolt Q1 is sandwiched between the base member 3 and the first narrowing member 5 and temporarily fixed. In addition, the elastic member 9 presses and urges the first base member 30 and the second base member 40 to temporarily fix the first base member 30 and the second base member 40 in a state where the suspension bolt P is sandwiched. The elastic member 9 attached to the second connecting bolt 8 presses and urges the second narrowing member 6 against the base member 3, and the second narrowing member 6 is interposed between the base member 3 and the second narrowing member 6. Temporarily fasten with two anti-shock bolts Q2. In this way, the temporary fixing of the base member 3 to the suspension bolt P and the temporary fixing of the two bracing bolts Q to the base member 3 can be performed simultaneously.

その後、第一狭着部材５及び第一振止ボルトＱ１の角度調整を行って第一連結ボルト７を締結し、第二狭着部材６及び第二振止ボルトＱ２の角度調整を行って第二連結ボルト８を締結する。２本の振止ボルトＱが、対応する連結ボルト７，８の締結によってベース部材３と対応する狭着部材５，６との間に狭着固定されるので、互いに交差する３本のボルトどうしを容易に連結することができる。 Thereafter, the angle of the first narrowing member 5 and the first rocking bolt Q1 is adjusted to fasten the first connecting bolt 7, and the angle of the second narrowing member 6 and the second rocking bolt Q2 is adjusted. Fasten the two connecting bolts 8. Since the two brace bolts Q are tightly fixed between the base member 3 and the corresponding narrow members 5 and 6 by fastening the corresponding connecting bolts 7 and 8, the three bolts intersecting each other Can be easily connected.

また、ボルト連結具１を構成する全ての部品が仮組された状態で、それらをまとめて取り扱いながら取付作業を行うことができる。しかも、上述したように吊ボルトＰにベース部材３が仮止めされ、かつ、ベース部材３に２本の振止ボルトＱが仮止めされた状態で、取付作業を容易に行うことができ、高所作業であっても安全である。 In addition, in a state where all the parts constituting the bolt connector 1 are temporarily assembled, the mounting operation can be performed while collectively handling them. Moreover, as described above, the base member 3 is temporarily fixed to the suspension bolt P, and the two work bolts Q are temporarily fixed to the base member 3, so that the mounting operation can be easily performed. It is safe even at work.

図２及び図４に示すように、第二狭着部材６は、第一ベース部材３０と第二ベース部材４０との一体化状態で、第一ベース部材３０と第二ベース部材４０とに跨って配置される。このため、第一ベース部材３０と第二ベース部材４０とが拡開するのを第二狭着部材６によって抑制することができ、吊ボルトＰに対するベース部材３の取付状態を安定化させることができる。 As shown in FIGS. 2 and 4, the second narrowing member 6 straddles the first base member 30 and the second base member 40 in an integrated state of the first base member 30 and the second base member 40. Arranged. Therefore, the first base member 30 and the second base member 40 can be prevented from expanding by the second narrowing member 6, and the attachment state of the base member 3 to the suspension bolt P can be stabilized. it can.
