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6069453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. 6069453 (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.

しかし、特許文献1のボルト連結具では、ベース部材が第一ベース部材〔外側狭着体1A〕及び第二ベース部材〔内側狭着体1B〕の2部材で構成され、これらは、吊ボルトの両側で2本の連結ボルトによって締結されて一体化されている。このような構成のボルト連結具を吊ボルトに取り付けるには、1本の連結ボルトで仮組された第一ベース部材と第二ベース部材とで吊ボルトを挟み込んだ後(特許文献1の図8(イ))、2本目の連結ボルトを新たに取り付ける(同図(ロ))。その後、その連結ボルトに2つ目の狭着部材を新たに取り付けてから、当該連結ボルトを締結する(同図(ハ))。   However, in the bolt connector disclosed in Patent Document 1, the base member is composed of two members, a first base member [outer narrow body 1A] and a second base member [inner narrow body 1B]. It is fastened and integrated by two connecting bolts on both sides. In order to attach the bolt connector having such a configuration to the suspension bolt, the suspension bolt is sandwiched between the first base member and the second base member temporarily assembled with one connection bolt (FIG. 8 of Patent Document 1). (A)) A second connecting bolt is newly attached ((B) in the figure). Thereafter, a second narrowing member is newly attached to the connecting bolt, and then the connecting bolt is fastened ((c) in the figure).

このように、特許文献1のボルト連結具では、ベース部材を構成する第一ベース部材と第二ベース部材とを一体化する2本の連結ボルトのうちの少なくとも1本を取り外した状態で、吊ボルトに対する取付作業を行う必要がある。当然、2つの狭着部材のうちの少なくとも1つも取り外した状態で作業を行う必要がある。このため、互いに独立した複数部材を同時に取り扱わなければならず、取付作業に手間取る可能性がある。また、そのような取付作業が高所で行われる場合には、部品の一部が落下する虞もある。   As described above, in the bolt connector of Patent Document 1, the hanger is removed in a state in which at least one of the two connecting bolts integrating the first base member and the second base member constituting the base member is removed. It is necessary to perform installation work on the bolt. Naturally, it is necessary to perform the operation with at least one of the two narrowing members removed. For this reason, it is necessary to handle a plurality of members independent from each other at the same time, and there is a possibility that it takes time for mounting work. In addition, when such an attachment operation is performed at a high place, there is a possibility that a part of the component falls.

特許第6069453号公報Japanese Patent No. 6069453

3本のボルトどうしを容易に連結することができ、しかも、容易かつ安全に取付作業を行うことができるボルト連結具の実現が望まれる。   It is desired to realize a bolt connector that can easily connect three bolts and that can be mounted easily and safely.

本発明に係るボルト連結具は、
吊ボルトと第一振止ボルトと第二振止ボルトとを連結するボルト連結具であって、
ベース部材と、第一狭着部材と、第二狭着部材と、第一連結ボルトと、第二連結ボルトと、を備え、
前記第一連結ボルトの締結によって前記ベース部材と前記第一狭着部材との間に前記第一振止ボルトが狭着固定され、
前記第二連結ボルトの締結によって前記ベース部材と前記第二狭着部材との間に前記第二振止ボルトが狭着固定され、
前記ベース部材が、一体化状態で前記吊ボルトを狭着固定する第一ベース部材と第二ベース部材とを有し、
前記第一連結ボルト及び前記第二連結ボルトのうちの前記第一連結ボルトだけの締結によって前記第一ベース部材と前記第二ベース部材とが前記一体化状態となるように構成されている。
The bolt connector according to the present invention is
A bolt connector for connecting the suspension bolt, the first bracing bolt and the second bracing bolt,
A base member, a first narrowing member, a second narrowing member, a first connection bolt, and a second connection bolt,
The first bracing bolt is tightly fixed between the base member and the first narrowing member by fastening the first connecting bolt,
The second bracing bolt is tightly fixed between the base member and the second narrowing member by fastening the second connecting bolt,
The base member has a first base member and a second base member for tightly fixing the suspension bolt in an integrated state;
The first base member and the second base member are configured to be in the integrated state by fastening only the first connection bolt of the first connection bolt and the second connection bolt.

この構成によれば、2本の振止ボルトが、対応する連結ボルトの締結によってベース部材と対応する狭着部材との間に狭着固定されるので、吊ボルトと第一振止ボルトと第二振止ボルトとを容易に連結することができる。また、上記の構成では、第一連結ボルトだけの締結によって第一ベース部材と第二ベース部材とが一体化状態となり、吊ボルトの狭着固定において第二連結ボルトは寄与しない。このため、第二連結ボルト及び第二狭着部材をベース部材から完全に取り外さずとも、吊ボルトに対する取付作業を行うことができる。すなわち、緩んだ状態の第一連結ボルト及び第二連結ボルトを介してベース部材(第一ベース部材及び第二ベース部材)と第一狭着部材と第二狭着部材と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。よって、取付作業を容易に行うことができ、そのような取付作業が高所で行われる場合でも安全である。
従って、3本のボルトどうしを容易に連結することができ、しかも、容易かつ安全に取付作業を行うことができるボルト連結具を提供することができる。
According to this configuration, the two bracing bolts are fixed tightly between the base member and the corresponding narrowing member by fastening the corresponding connecting bolts. The two steady bolts can be easily connected. Moreover, in said structure, a 1st base member and a 2nd base member will be in an integrated state by fastening only a 1st connection bolt, and a 2nd connection bolt does not contribute in the tight fixation of a suspension bolt. For this reason, it is possible to perform the attaching operation to the suspension bolt without completely removing the second connecting bolt and the second narrowing member from the base member. That is, a state in which the base member (first base member and second base member), the first narrowing member, and the second narrowing member are temporarily assembled via the loosened first coupling bolt and second coupling bolt. Thus, the mounting work can be performed while handling them together. Therefore, the attachment work can be easily performed, and it is safe even when such an attachment work is performed at a high place.
Therefore, it is possible to provide a bolt connector that can easily connect the three bolts and that can be easily and safely attached.

In the present embodiment, the second base member 40 is disposed on the opposite side of the first base member 30 from the first narrowing member 5. 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 in the same size as the first mounting portion 31 of the first base member 30 or slightly smaller than that. The overlapping portion 41 has a burring tap portion 47 in which an internal thread is cut on the inner peripheral surface. The overlapping portion 41 has a plurality of (four in the present example, the same number as the engaging protrusions 34) engaging holes 46 around the burring tap portion 47.

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のコーナー部に対面するように重合部41から第二取付部32側に向かって延出している。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の重合部41とは反対側の部位は、第一ベース部材30の第二取付部32に当接しているとともに、その先端部が部分的に折り返されて折返部43となっている(図4を参照)。   The curved portion 42 extends from the overlapping portion 41 toward the second attaching portion 32 so as to face the corner portion of the first base member 30 in a state where the overlapping portion 41 is overlapped with the first attaching portion 31. Yes. 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 portion of the bending portion 42 opposite to the overlapping portion 41 is in contact with the second mounting portion 32 of the first base member 30 and a tip portion thereof is partially folded to form a folded portion 43. (See FIG. 4).

図4に示すように、第二ベース部材40は、重合部41における湾曲部42とは反対側の端部に屈曲部44を有する。屈曲部44は、第一ベース部材30の第一取付部31との間のなす角が鋭角(本例ではおよそ45°)となるように屈曲されている。また、第二ベース部材40は、重合部41から湾曲部42に亘って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。   As shown in FIG. 4, the second base member 40 has a bent portion 44 at the end of the overlapping portion 41 opposite to the curved portion 42. The bent portion 44 is bent so that an angle formed with the first mounting portion 31 of the first base member 30 is an acute angle (about 45 ° in this example). The second base member 40 has reinforcing ribs 45 extending from the overlapping portion 41 to the curved portion 42 along the respective upper and lower edges.

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(本例では第一ベース部材30の第一取付部31及び第二取付部32)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(本例では第一ベース部材30の第一取付部31)に対向するベース対向部51と、ベース対向部51の外縁に沿って立設する側板部53とを有する。本実施形態のベース対向部51は、平板状に形成され、ベース部材3から側板部53の高さ分だけ離間して対向するように配置されている。   The first narrowing member 5 and the second narrowing member 6 are fixed to both end portions of the base member 3 (in this example, the first mounting portion 31 and the second mounting portion 32 of the first base member 30), respectively. Fix the bolt Q tightly. The first narrowing member 5 includes a base facing portion 51 that faces the base member 3 (in this example, the first mounting portion 31 of the first base member 30), and a side plate portion that stands up along the outer edge of the base facing portion 51. 53. The base facing portion 51 of the present embodiment is formed in a flat plate shape, and is disposed so as to face the base member 3 by being separated by the height of the side plate portion 53.

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。ベース対向部51はD字状に形成されている。側板部53は、ベース対向部51の形状に応じて、円弧状部とその両端から延びる一対の平坦部とを有する。一対の平坦部は互いに平行に配置されている。側板部53は、一対の平坦部のそれぞれに係止切欠部54を有する。係止切欠部54は、ベース部材3側に向かって開口するように形成されている。係止切欠部54には、第一振止ボルトQ1における軸方向の異なる2箇所がそれぞれ係止される。   A bolt insertion hole 52 through which the first connection bolt 7 is inserted is formed in the base facing portion 51. The base facing portion 51 is formed in a D shape. The side plate portion 53 includes an arc-shaped portion and a pair of flat portions extending from both ends thereof according to the shape of the base facing portion 51. The pair of flat portions are arranged in parallel to each other. The side plate portion 53 has a locking notch portion 54 in each of the pair of flat portions. The locking notch 54 is formed so as to open toward the base member 3 side. In the locking notch portion 54, two different axial directions of the first rocking bolt Q1 are respectively locked.

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(本例では第一ベース部材30の第二取付部32)に対向するベース対向部61と、ベース対向部61の外縁に沿って立設する側板部63とを有する。ベース対向部61には、第二連結ボルト8が挿通されるボルト挿通孔62が形成されている。側板部63には、第二振止ボルトQ2における軸方向の異なる2箇所がそれぞれ係止される一対の係止切欠部64が形成されている。   The second narrowing member 6 has the same configuration as the first narrowing member 5. That is, the second narrowing member 6 is erected along the base facing portion 61 facing the base member 3 (in this example, the second mounting portion 32 of the first base member 30) and the outer edge of the base facing portion 61. Side plate portion 63. A bolt insertion hole 62 through which the second connection bolt 8 is inserted is formed in the base facing portion 61. The side plate part 63 is formed with a pair of locking notches 64 in which two different axial directions of the second rocking bolt Q2 are locked.

係止切欠部54や係止切欠部64の内縁は、先端側に向かって次第に厚みが薄くなるように、先鋭状に形成されていることが好ましい。このようにすれば、係止切欠部54が第一振止ボルトQ1のネジ部に係合して、第一狭着部材5に対して第一振止ボルトQ1が軸ズレするのを抑制することができる。また、係止切欠部64が第二振止ボルトQ2のネジ部に係合して、第二狭着部材6に対して第二振止ボルトQ2が軸ズレするのを抑制することができる。   The inner edges of the locking notch 54 and the locking notch 64 are preferably formed in a sharp shape so that the thickness gradually decreases toward the tip side. If it does in this way, the latching notch part 54 will engage with the thread part of the 1st rocking bolt Q1, and it will suppress that the 1st rocking bolt Q1 is axially displaced with respect to the 1st narrowing member 5. FIG. be able to. Moreover, it is possible to suppress the second notch bolt Q2 from being axially displaced with respect to the second narrowing member 6 by engaging the locking notch 64 with the threaded portion of the second notch bolt Q2.

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(本例では第一ベース部材30の第一取付部31)に第一狭着部材5を取り付ける。その際、第一狭着部材5の側板部53に形成された係止切欠部54に第一振止ボルトQ1が係止された状態で、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 first mounting portion 31 of the first base member 30). At that time, the first connecting bolt 7 is fastened to the base member 3 in the state where the first rocking bolt Q1 is locked to the locking notch 54 formed in the side plate portion 53 of the first narrowing member 5. The first anti-vibration bolt Q1 is tightly fixed between the narrow attachment member 5. 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、第一ベース部材30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及び第一ベース部材30を貫通し、第二ベース部材40の重合部41に形成されたバーリングタップ部47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のコーナー部と第二ベース部材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 first base member 30 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 first base member 30 and is screwed into a female screw of a burring tap portion 47 formed in the overlapping portion 41 of the second base member 40. Thus, the first base member 30 and the second base member 40 are integrated with each other by fastening the first connecting bolt 7, and the corner portion of the first base member 30 and the curve of the second base member 40 are in this integrated state. A suspension bolt P is fixed tightly between the portion 42.

図5に示すように、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、第一取付部31に形成された係合突部34が重合部41に形成された係合孔46に進入するようになっている。このため、第一ベース部材30の第一取付部31と第二ベース部材40の重合部41との面方向での位置ズレを抑制することができる。よって、吊ボルトPに対してベース部材3を安定的に取り付けることができる。本実施形態では、第一取付部31に設けられた係合突部34と、重合部41に設けられて係合突部34が進入する係合孔46とにより、一体化状態で第一取付部31と重合部41との相対位置関係を規制する位置規制手段Rが構成されている。   As shown in FIG. 5, an engagement hole in which an engagement protrusion 34 formed in the first attachment portion 31 is formed in the overlapping portion 41 in an integrated state of the first base member 30 and the second base member 40. 46 is entered. For this reason, the position shift in the surface direction of the 1st attaching part 31 of the 1st base member 30 and the superposition | polymerization part 41 of the 2nd base member 40 can be suppressed. Therefore, the base member 3 can be stably attached to the suspension bolt P. In the present embodiment, the first attachment is integrally performed by the engagement protrusion 34 provided in the first attachment portion 31 and the engagement hole 46 provided in the overlapping portion 41 and into which the engagement protrusion 34 enters. Position restricting means R for restricting the relative positional relationship between the portion 31 and the overlapping portion 41 is configured.

なお、第二ベース部材40の湾曲部42の内面には、吊ボルトPのネジ部に係止される係止突起42Aが突出形成されている(図3を参照)。係止突起42Aは、吊ボルトPの軸方向の複数箇所に形成されていることが好ましい。このような係止突起42Aを有することで、吊ボルトPに対してベース部材3ひいてはボルト連結具1が軸ズレするのを抑制することができる。   Note that a locking projection 42A that is locked to the threaded portion of the suspension bolt P is formed on the inner surface of the curved portion 42 of the second base member 40 (see FIG. 3). The locking projections 42A are preferably formed at a plurality of locations in the axial direction of the suspension bolt P. By having such a locking protrusion 42A, the base member 3 and thus the bolt connector 1 can be prevented from being displaced with respect to the suspension bolt P.

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の側板部63に形成された係止切欠部64に第二振止ボルトQ2が係止された状態で、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, the second connecting bolt 8 is fastened to the base member 3 in the state where the second rocking bolt Q2 is locked to the locking notch 64 formed in the side plate portion 63 of the second narrowing member 6. The second anti-vibration bolt Q <b> 2 is fixed tightly between the narrow attachment member 6. 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。但し、本実施形態では、第一ベース部材30と第二ベース部材40との一体化状態の維持促進のために第二連結ボルト8が寄与し得るように構成されている。図4及び図6に示すように、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、第二ベース部材40における折返部43の端縁43eが第二連結ボルト8のネジ部83に係止されている。吊ボルトPに対して、第一連結ボルト7の挿通部(本例ではバーリングタップ部47)とは反対側で折返部43の端縁43eが第二連結ボルト8のネジ部83に係止されることで、第一ベース部材30と第二ベース部材40とが拡開するのを抑制することができる。   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. However, in this embodiment, it is comprised so that the 2nd connection bolt 8 can contribute for the maintenance promotion of the integrated state of the 1st base member 30 and the 2nd base member 40. FIG. As shown in FIGS. 4 and 6, when the first base member 30 and the second base member 40 are integrated, the edge 43 e of the folded portion 43 of the second base member 40 is the threaded portion of the second connecting bolt 8. 83 is locked. The edge 43e of the folded portion 43 is locked to the threaded portion 83 of the second connecting bolt 8 on the opposite side of the suspension bolt P from the insertion portion of the first connecting bolt 7 (burring tap portion 47 in this example). Thereby, it can suppress that the 1st base member 30 and the 2nd base member 40 expand.

本実施形態では、図3及び図7に示すように、第一連結ボルト7及び第二連結ボルト8に弾性部材9がそれぞれ装着されている。弾性部材9は、第一ベース部材30の第一取付部31と第一狭着部材5のベース対向部51との間、及び、第一ベース部材30の第二取付部32と第二狭着部材6のベース対向部61との間に配置されている。弾性部材9としては、コイルばねが用いられている。   In this embodiment, as shown in FIGS. 3 and 7, elastic members 9 are attached to the first connecting bolt 7 and the second connecting bolt 8, respectively. The elastic member 9 is provided between the first mounting portion 31 of the first base member 30 and the base facing portion 51 of the first narrowing member 5 and between the second mounting portion 32 of the first base member 30 and the second narrowing. It arrange | positions between the base opposing parts 61 of the member 6. FIG. As the elastic member 9, a coil spring is used.

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8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及び第一ベース部材30を貫通させて第二ベース部材40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第一ベース部材30のコーナー部(又は第二ベース部材40の湾曲部42)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からコーナー部を経て第二取付部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. 8, 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 first base member 30 and is loosely locked to the second base member 40. In this temporarily assembled state, the first base member 30 and the second base member 40 are connected by the first connecting bolt 7 to the corner portion (or the second base member) of the first base member 30 where the suspension bolt P is to be disposed. Forty curved portions 42) are locked only on one side of the base member 3 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 through the corner portion.

この仮組状態で、例えば第一ベース部材30の第一取付部31と第二ベース部材40の屈曲部44とを摘み操作する等して第一連結ボルト7側の弾性部材9を圧縮変形するように押圧し、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8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)。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、当該弾性部材9が第二ベース部材40に対して第一ベース部材30を圧接付勢する状態となり、吊ボルトPにベース部材3が仮止めされる。   In this temporarily assembled state, for example, the first attachment portion 31 of the first base member 30 and the bent portion 44 of the second base member 40 are operated to compress and deform the elastic member 9 on the first connecting bolt 7 side. The first base member 30 and the second base member 40 are expanded (see FIG. 8). 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). Thereafter, when the external pressure on the elastic member 9 is released, the elastic member 9 presses and urges the first base member 30 against the second base member 40, and the base member 3 is temporarily fixed to the suspension bolt P. Is done.

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狭着部材5の係止切欠部54に第一振止ボルトQ1を係止させ、第一連結ボルト7を締結する。また、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狭着部材6の係止切欠部64に第二振止ボルトQ2を係止させ、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。   Then, the angle of the 1st narrowing member 5 and the 1st rocking bolt Q1 is adjusted, the 1st rocking bolt Q1 is latched by the latching notch part 54 of the 1st narrowing member 5, and the 1st connection bolt 7 Conclude. Further, the angle of the second narrowing member 6 and the second rocking bolt Q2 is adjusted to lock the second rocking bolt Q2 in the locking notch 64 of the second narrowing member 6, and the second connecting bolt 8 Conclude. 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ので、取付作業を容易に行うことができる。特に高所においても、取付作業を安全に行うことができる。   Further, since all the parts constituting the bolt connector 1 are temporarily assembled, the mounting work can be performed while handling them together, so that the mounting work can be easily performed. The mounting operation can be performed safely even at high places.

The bolt insertion hole 52 of the base facing portion 51 has a larger diameter than the shaft portion 72 of the first connection bolt 7 and a smaller diameter than the elastic member 9, whereas the bolt insertion hole 58 of the spaced-apart arrangement portion 57 has an elastic member. The diameter is larger than 9. For this reason, as shown in FIG. 11, the elastic member 9 attached to the first connection bolt 7 passes through the spaced-apart arrangement portion 57 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 57 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65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67とを有する。離間配置部67のボルト挿通孔68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。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67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67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 65 that is generally along the outer surface of the second rocking bolt Q <b> 2, and the base member 3 that is opposite to the base member 3.

The bolt insertion hole 68 of the spaced apart arrangement portion 67 is formed to have a larger diameter than the bolt insertion hole 62 of the base facing portion 61. The elastic member 9 attached to the shaft portion 82 of the second connection bolt 8 passes through the spaced-apart arrangement portion 67 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 portion 67 is an elastic member accommodation space A in which the elastic member 9 attached to the second connecting bolt 8 is accommodated.

本実施形態のボルト連結具1も、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12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38,42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38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 also 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. 12, the second connecting bolt 8 to which the elastic member 9 is attached is loosened to the first base member 30 through the second narrowing member 6 and the first attachment member 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 38 and 42 where the suspension bolt P is to be arranged. 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 38.

なお、上記の仮止状態で、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、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を圧接付勢する。このため、吊ボルトPにベース部材3を仮止めするのに加え、合わせて、ベース部材3に2本の振止ボルトQを仮止めすることができる。   The elastic member 9 attached to the first connection bolt 7 in the temporarily fixed state presses and urges the first narrowing member 5 against the base member 3 and is attached to the second connection bolt 8. The elastic member 9 presses and urges the second narrowing member 6 against the base member 3. For this reason, in addition to temporarily fixing the base member 3 to the suspension bolt P, it is possible to temporarily fix the two retaining bolts Q to the base member 3.

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9及び図11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. 9 and 11, 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.
