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. 6907710 (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.

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 connecting tool of Patent Document 1, an elastic member [coil spring 4] is attached to each of the two connecting bolts, and this elastic member is a first base member [outer narrow fitting] constituting the base member. Body 1A] and the second base member [inner narrowed body 1B] are pressure-welded to each other. This makes it possible to easily temporarily fix the base member composed of two members to the hanging 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 urges the two narrow-fitting members so as to separate them from the base member, so that when the anti-vibration bolt is narrowly fixed between the base member and the narrow-fitting member. In order to do this, the operator needs to work while firmly supporting the anti-vibration bolt. Therefore, there is a possibility that the mounting work may take time, and when such a mounting work is performed at a high place, the work may become more difficult.

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, in a state where the second anti-vibration bolt Q2 is accommodated in the curved portion 63 of the second narrowing member 6, the second narrowing member 6 is fastened between the base member 3 and the second narrowing member 6 by fastening the second connecting bolt 8.

The connecting bolt 7 is passed through the first narrowing member 5 and the second base member 40 and loosely fastened to the first base member 30. In this temporarily assembled state, the first base member 30 and the second base member 40 are provided by the first connecting bolt 7 with respect to the space between the curved portions 33 and 42, which are the positions where the hanging bolts P are planned to be arranged. The base member 3 is locked only on one side in the extending direction. In the present embodiment, the extending direction of the base member 3 is a direction from the first mounting portion 31 of the first base member 30 to 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 elastic member 9 on the first connecting bolt 7 side is pressed so as to be compressively deformed to expand the first base member 30 and the second base member 40 (see FIG. 5). Then, the suspension bolt P is slid and inserted in the radial direction between the first base member 30 and the second base member 40 through the gap G generated thereby (* Actually, the bolt connector 1 side is inserted.

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。 Further, in a state where all the parts constituting the bolt connector 1 are temporarily assembled, the mounting work can be performed while handling them together. Moreover, as described above, the mounting work can be easily performed with the base member 3 temporarily fixed to the suspension bolt P and the two anti-vibration bolts Q temporarily fixed to the base member 3, which is high. It is safe even if it is a local 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.
