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, a hanging device such as a cable rack, or the like may be suspended from a structure such as a ceiling slab by using hanging bolts. In such a case, in order to suppress the shaking movement of the suspension equipment due to an earthquake or the like, the suspension bolts are arranged in an intersecting posture with respect to the other suspension bolts located on both sides of the suspension bolts. It may be connected to each other to reinforce it. In this case, a bolt connector for connecting the hanging bolt and the two anti-vibration 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 attachment 1], two narrow attachment members [diagonal support 3], and two connecting bolts for fixing the narrow attachment member to the base member [ It is equipped with a connecting bolt 2]. Then, by overlapping the narrowing member and the base member and connecting them with connecting bolts, the angle of the anti-vibration bolt [long bolt Q] can be adjusted around the connecting bolt, and the anti-vibration bolt is narrowly attached. It is crimped and fixed to the base member with a member. It is stated in Patent Document 1 that this makes it possible to easily prevent the suspension bolt from swaying.

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 of Patent Document 1, the base member is composed of two members, a first base member [outer narrowed body 1A] and a second base member [inner narrowed body 1B], and these are of hanging bolts. 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 by one connecting bolt (FIG. 8 of Patent Document 1). (A)) A second connecting bolt is newly attached (Fig. (B)). After that, 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 connecting tool of Patent Document 1, at least one of the two connecting bolts that integrate the first base member and the second base member constituting the base member is removed and suspended. It is necessary to perform mounting work on the bolt. Of course, it is necessary to perform the work with at least one of the two narrowing members removed. Therefore, it is necessary to handle a plurality of independent members at the same time, which may take time for the mounting work. Further, when such mounting work is performed at a high place, a part of the parts may fall.

By fastening the first connecting bolt, the first anti-vibration bolt is narrowly fixed between the base member and the first narrowing member.
By fastening the second connecting bolt, the second anti-vibration bolt is narrowly fixed between the base member and the second narrowing member.
The base member has a first base member and a second base member for narrowly fixing the hanging 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 connecting bolt among the first connecting bolt and the second connecting 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。

(Ii) It can be easily connected to the anti-vibration bolt. Further, in the above configuration, the first base member and the second base member are integrated by fastening only the first connecting bolt, and the second connecting bolt does not contribute to the narrow attachment fixing of the hanging bolt. Therefore, the attachment work to the hanging bolt can be performed 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 connecting bolt and second connecting bolt. Then, the installation work can be performed while handling them all together. Therefore, the mounting work can be easily performed, and it is safe even when such mounting work is performed at a high place.
Therefore, it is possible to provide a bolt connector that can easily connect the three bolts to each other and that can easily and safely perform the mounting work.

The base facing portion 51 is formed in a D shape. The side plate portion 53 has an arc-shaped portion and a pair of flat portions extending from both ends thereof, depending on the shape of the base facing portion 51. The pair of flat portions are arranged parallel to each other. The side plate portion 53 has a locking notch 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. Two locations of the first anti-vibration bolt Q1 having different axial directions are locked in the locking notch 54.

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.

At that time, with the first anti-vibration bolt Q1 locked in the locking notch 54 formed in the side plate portion 53 of the first narrowing member 5, the first connecting bolt 7 is fastened to the base member 3 and the third. The first anti-vibration bolt Q1 is narrowly fixed to the narrow fitting member 5. In this way, the first narrowing member 5 is connected to the base member 3 so as to be relatively displaceable by the first connecting bolt 7, and the first anti-vibration bolt Q1 is sandwiched and held between the first narrowing member 5 and the base member 3. ..

The second connecting bolt 8 penetrates the second narrowing member 6 and is screwed into the female screw of the burring tap portion 35 formed on the second mounting portion 32. Then, with the second anti-vibration bolt Q2 locked in the locking notch 64 formed in the side plate portion 63 of the second narrowing member 6, the base member 3 and the second are second by fastening the second connecting bolt 8. The second anti-vibration bolt Q2 is narrowly fixed to the narrowing member 6. In this way, the second narrowing member 6 is connected to the base member 3 so as to be relatively displaceable by the second connecting bolt 8, and the second anti-vibration bolt Q2 is sandwiched and held between the second narrowing member 6 and the base member 3. ..
