Description

【０００１】
【発明の属する技術分野】
本発明は、線材の組付けにより構成された配線・配管材用受具の連結具に関するものである。
【０００２】
【従来の技術】
配線・配管材用受具としては長手方向に延設された左右一対の親桁間に適宜間隔をおいて複数の子桁を架設して梯子状に形成したラダータイプなどの他、近年は、メッシュタイプの受具が用いられるようになっている。このメッシュタイプの受具は、図３に示すように、金属からなる複数の線材７を横筋５及び縦筋６として縦横の網目状に組合わせ、線材７の交差部分を溶接して形成されている。配線・配管材が布設される布設路はこの複数の線材を組付けてなる所定長さの受具同士１を長さ方向に連結することによって形成されている。
【０００３】
この受具同士の連結は、一端側及び他端側の双方からそれぞれ順に受具２同士を連結して接近させ、最終的に両終端の受具２同士を連結することによって行なっていた。ここで、前記受具２同士の連結手段として、例えば、ドイツ連邦共和国出願公開公報第２０３６３２５号に記載の連結具３１が開示されている。前記連結具３１は、図１５に示すように、２枚の挟持金具３２及び挟持金具３３をねじ３４で引寄せて線材を挟持するものであり、両受具２における端部の横筋５の線材７同士を並置し、この２本の線材７を前記連結具３１の挟持金具３２及び挟持金具３３で挟持することによって前記受具２同士を連結することができる。
【０００４】
また、受具を順に連結して設置し、所定の位置、例えば、壁際丁度の位置で受具の配設を終了する場合も、同様にして、受具２の端部同士を、例えば、２枚の挟持金具３２、挟持金具３３及びねじ３４からなる前記連結具３１によって連結することができる。
【０００５】
【発明が解決しようとする課題】
しかし、配線・配管材の布設路を形成すべく、一端側及び他端側の双方からそれぞれ順に受具２同士を連結して接近させ、最終的に両終端の受具２同士を連結する場合、また、受具を順に連結して設置して所定の位置、例えば、壁際丁度の位置で受具の配設を終了する場合に、終端部における受具２は、通常は、寸法的に丁度の長さでは終わらない。このため、いずれか一方の終端の受具２の一部を所定長さ切断して長さ調整を行なった後、前記連結具３１等で両方の終端の受具２同士を連結しなければならないが、これらの線材により組付けられた受具の一部を切断し、長さ調整する作業は極めて面倒かつ困難であった。
【０００６】
そこで、本発明は、線材の組付けにより構成された受具を切断することなく、簡単に長さ調整して、受具同士を連結することができ、また、受具の配設を所定の終端位置で終了させることができる配線・配管材用受具の連結具の提供を課題とするものである。
【０００７】
【課題を解決するための手段】
請求項１に記載の発明は、線材の組付により構成された受具同士を長手方向における適宜長が上下に重ね合わされた状態で連結すべく、前記上下に重ね合わされた上側の受具を構成する上側の線材に対し、前記受具の内部側から係合する上側の連結具本体と、下側の受具を構成する下側の線材に対し、前記受具の外部側から係合する下側の連結具本体と、前記上具の線材と下側の線材とを挟持すべく、前記上側の連結具本体と下側の連結具本体とを相対的に引寄せるための引寄せ手段と、を備えた受具の連結具であって、上側または下側の連結具本体は、相手の連結具本体に当接してそれ以上の引寄せを防止し、前記上側の連結具本体と下側の連結具本体との引寄せによって生じる上側の線材及び下側の線材の変形を防止する変形防止部を、相手の連結具本体に向けて突出形成したことを特徴とするものである。
【０００８】
請求項２に記載の発明は、線材の組付けにより構成された受具同士を長手方向における適宜長が上下に重ね合わされた状態で連結すべく、前記上下に重ね合わされた上側の受具を構成する上側の線材に対し、前記受具の内部側から係合する上側の連結具本体と、下側の受具を構成する下側の線材に対し、前記受具の外部側から係合する下側の連結具本体と、前記上側の線材と下側の線材とを挟持すべく、前記上側の連結具本体と下側の連結具本体とを相対的に引寄せるための引寄せ手段と、上側の連結具本体と下側の連結具本体との間に介在して両連結具本体の所定以上の引寄せを防止して、前記上側の連結具本体と下側の連結具本体との引寄せに生じる上側の線材及び下側の線材の変形を防止する変形防止部材と、を備えることを特徴とするものである。
【０００９】
【発明の実施の形態】
以下、本発明の実施例を図１乃至図１４に基づいて説明する。
図において、配線・配管材の布設路を長手方向に直線状に形成すべく、複数の受具２が連結具１１によって連結固定されており、これらの受具２と前記連結具１１とによって線材の連結装置１が構成されている。
【００１０】
前記受具２は配線・配管材Ｃが載置される載置部３と、この載置部３の両側に立設した立設部４とで構成されており、長手方向即ち布設方向と直交する方向に配置された横筋５と、この横筋５の下側において長手方向に配置された縦筋６とを縦横に組付けることによって形成されている。前記横筋５及び縦筋６は金属製の丸棒、角棒、断面略小判形の棒材等からなる線材７によって形成されており、これらの線材７を溶接によって網目状に組付けられている。
【００１１】
前記受具２において、図４に示すように、前記横筋５の線材７は立設部４におけるほぼ中間部に屈曲した段部５ａが形成され、前記段部５ａより下方部分は上端部に対して段差ｂの寸法だけ受具２の内側に突出している。また、横筋５の線材７と立設部４の上端において布設方向に架設された縦筋６の線材７ａとが溶接された融着部８においては前記横筋５の線材７及び縦筋６の線材７ａ双方の溶出によって、溶出代ａだけ前記横筋５の線材７と縦筋６の線材７ａとの当接面が受具２の内部側に陥入している。ここで、前記段差ｂは少なくとも溶出代ａより大きく形成されている、即ち、ｂ＞ａとなっている。したがって、図４において、Ｌ１は融着部８における前記線材７ａの内側の間隔寸法、Ｌ２は横筋５の線材７の立設部４における外側の間隔寸法を示すとすると、常にＬ１＞Ｌ２の関係が成立している。
【００１２】
ここで、仮に、立設部４における横筋５の線材７に前記段部５ａが形成されていないと、ｂ＝０であるから、Ｌ１＜Ｌ２となって、一の受具２における横筋５の線材７と他の受具２における立設部４の上端の線材７ａとが干渉し、一の受具２を他の受具２の内部に嵌入させることができない。
【００１３】
ところが、本実施例の受具２は、ｂ＞ａとする段部５ａが形成され、Ｌ１＞Ｌ２の関係の関係が成立し、かつ、立設部４には上端の線材７ａのみが設けられている。このため、一の受具２の横筋５の線材７を他の受具２の横筋５の線材７に対して布設方向にずらした状態で受具２同士を上下に重ね合わせるときに、一の受具２における横筋５の線材７を、他の受具２における立設部４の上端の線材７ａと干渉することなくこの線材７ａ間に嵌入させることができる。したがって、図５に示すように、一の受具２と他の受具２とは上下方向に相互に重ね合わせることができるようになっている。
【００１４】
次に、前記連結具１１は、上側に配置された受具２における上側の縦筋６の線材７と係合する上側の連結具本体１２と、下側に配置された受具２における下側の縦筋６の線材７と係合する下側の連結具本体１２と、これらの上側の連結具本体１２と下側の連結具本体１２とを上下方向に相対的に引寄せるための引寄手段となるボルト２１とで構成されている。
【００１５】
前記連結具本体１２は、図６に示すように、金属製の矩形状の平板をプレス加工によって折曲され、平板部１３の両端に略山形状の係合部１４が形成されている。更に、前記平板部１３の中央部に前記ボルト２１が挿通される挿通孔１５が設けられ、その両側に補強用のリブ１６が形成されている。前記平板部１３の両端に形成された一対の係合部１４の間隔は受具２の載置部３において隣合う縦筋６の間隔と等しい大きさに形成されており、前記縦筋６の線材７と直交する方向には移動しないようになっている。なお、前記係合部１４は略山形に形成されているが、線材７の外形状に対応した円弧形状等に形成してもよい。
【００１６】
更に、前記上側の連結具本体１２と下側の連結具本体１２との間には、ボルト２１及びナット２２で締付けたときに、これらの連結具本体１２が変形するのを防止するために、所定長さの線材からなる変形防止部材２３が介在している。
【００１７】
次に、上記のように構成された本実施例の連結具によって、双方向から順に連結した終端の受具同士の長さを調整するために、或いは、受具の配設を所定の終端位置で終了させるために、受具同士を連結する方法を説明する。
【００１８】
まず、布設路の終端において受具２を切断することなく、一方の受具２の一部を他方の受具の内部側に上方から収容し、長手方向における適宜長を上下に重ね合わせる。次に、下側の受具２の下にこの受具２の外部側から下側の連結具本体１２を２個配置し、この連結具本体１２の係合部１４を前記受具２の載置部３における２本の縦筋６の線材７に係合させ、この状態で、前記下側の連結具本体１２と対向させて上側の受具２の上にこの受具２の内部側から上側の連結具本体１２を２個配置し、前記受具２の載置部３における２本の縦筋６の線材７に前記連結具本体１２の係合部１４をそれぞれ係合させる。次に、両連結具本体１２の挿通孔１５にボルト２１を貫挿し、ナット２２を螺着して締付ける。なお、上下の連結具本体１２の少なくとも一方の挿通孔１５をねじ孔とすれば、ボルト２１のみで締付けることもでき、ナット２２は不要となる。
【００１９】
ここで、図１及び図２に示すように、前記上側の受具２の載置部３の縦筋６が下側の受具２の載置部３における１本のみの横筋５上に載置されている場合には、前記下側の受具２における１本の横筋５を支点として傾斜し、上下２個の連結具本体１２も相互に傾斜した状態で締付けられることになる。すると、ボルト２１の頭部下面が上側の連結具本体１２の平板部１３に局部的に強く当接して、この連結具本体１２の平板部１３が凹み変形して好ましくない。そこで、前記ボルト２１及びナット２２で締付ける前に、予め、上側の受具２における載置部３の縦筋６の下側に変形防止部材２３を介在させておくことが必要である。変形防止部材２３としては、例えば、下側の受具２の横筋５の線材７と同一径で所定長さの線材で形成することができる。なお、この変形防止部材２３は請求項の変形防止部に相当するものである。
【００２０】
このようにして、ボルト２１及びナット２２の締付けにより、上側の受具２の線材７と下側の受具２の線材７とが上下方向に相対的に強く引寄せられ、縦筋６の線材７と連結具本体１２の係合部１４との間に摺動抵抗が働くため、両受具２は所定の位置で連結固定される。
【００２１】
ところで、前記連結具本体１２は、図７及び図８に示すように、平板部１３の一部に突片１３ａを形成してもよい。この突片１３ａは平板部１３の一部を略コ字状に切欠いた後、略コ字板部分を他の連結具本体１２と対向する側に直角に折曲することによって形成することができる。前記突片１３ａの高さは上下一対の連結具本体１２をボルト２１及びナット２２によって引寄せて前記突片１３ａの先端が互いに相手の平板部１３と当接したときに、両連結具本体１２の平板部１３が略平行状態となるような大きさに形成されている。
【００２２】
この突片１３ａを形成した連結具本体１２を使用した場合には、上下一対の連結具本体１２を引寄せて平板部１３が略平行状態となったときに両方の突片１３ａの先端は互いに相手の平板部１３と当接してそれ以上のボルト２１及びナット２２の締付けを防止することができる。このため、線材で形成した変形防止部材２３を一対の連結具本体１２の間に介在させた場合と同様に、ボルト２１及びナット２２の締付けによる平板部１３の中央部の凹み変形を防止することができる。なお、この平板部１３の突片１３ａも請求項の変形防止部に相当するものである。
【００２３】
次に、上記連結具１１の変形例を図９乃至図１４に示す。
図９において、連結具本体１２の係合部１４における線材７と当接する面にはパキング材１７が貼着されている。この実施例の場合には、連結具１１によって上側の受具２と下側の受具２とを連結した状態で連結具本体１２の係合部１４と線材７との摺動抵抗が増し、受具２に対して連結具１１が縦筋６の軸方向に移動するのがより一層防止され、前記連結具１１は受具２の一定位置に安定して保持される。なお、連結具本体１２の係合部１４における線材７と当接する面にはパッキング１７の他に樹脂コーティングなどを施してもよい。
【００２４】
次に、図１０において、連結具本体１２は金属製板ばね材で形成され、中央部が互いに膨出し、全体が円弧状に撓んでいる。この実施例の場合は、連結具１１の挿通孔１５にボルト２１を挿通し、ナット２２を螺着して締付けることにより、図１１に示すように、前記連結具本体１２の弾発力に抗して中央部が近接し、略平行状態となる。この状態では、前記連結具本体１２の中央部は元に戻ろうとする弾発力が互いに外方に作用するため、前記連結具本体１２の両端に設けられた係合部１４は、逆に、線材７を押圧する方向に働く。その結果、前記連結具本体１２の係合部１４と線材７との間の摺動抵抗が増大し、図９の場合と同様に、受具２に対して連結具１１が縦筋６の軸方向に移動するのがより一層防止され、連結具１１は受具２の一定位置に安定して保持される。
【００２５】
また、図１２において、連結具１１の連結具本体１２は平板部１３における係合部１４の形成された２辺と異なる辺のいずれか一方に、受具２の載置部３における横筋５の線材７と係合する断面略山形状のずれ防止部１８が一体に形成されている。この実施例の場合には、前記ずれ防止部１８が受具２の載置部３における横筋５の線材７と係合するため、図９乃至図１１に示した連結具本体１２の係合部１４と線材７との間の摺動抵抗によることなく、受具２に対して連結具１１が縦筋６の軸方向に移動するのを防止することができる。
【００２６】
更に、図１３において、連結具本体１２は平板部１３における一方の断面山形状をなす係合部１４の反対側端部に、段差を設けて側方に延出して受具２の縦筋６と当接する平板状の当接部１９が一体に形成されている。この実施例においては、ボルト２１及びナット２２によって締付けたときに、連結具本体１２の係合部１４及び当接部１９が受具２における隣合う縦筋６の線材７と当接し、上側の線材７と下側の線材７とが連結具１１によって挟持され、上側の受具２と下側の受具２とが連結固定される。特に、この実施例においては、連結具本体１２の当接部１９が平板状に形成されているので、受具２における隣合う縦筋６の線材７の間隔が異なる場合においても、連結具本体１２の係合部１４及び当接部１９が前記縦筋６の線材７と当接する。このため、縦筋６の線材７の間隔が異なる各種サイズの受具２に自在に対応して連結することができる。
【００２７】
なお、図１４においては、図１３の連結具本体１２の平板部１３における係合部１４及び当接部１９が形成された２辺と異なる辺のいずれか一側に、図１２のずれ防止部１８と同様のずれ防止部１８が一体に設けられている。したがって、この図１４に示す実施例においては、縦筋６の線材７の間隔が異なる各種サイズの受具２に自在に対応して連結することができるとともに、受具２に対して連結具１１が縦筋６の軸方向に移動するのを防止して連結具１１を安定して保持することができる。
【００２８】
このように、本実施例の配線・配管材用受具の連結装置は、線材７の組付けにより構成され、長手方向における適宜長が上下に重ね合わせ可能に形成された受具２と、前記適宜長が上下に重ね合わされた状態で前記受具２同士を連結すべく、前記上下に重ね合わされた上側の受具２を構成する上側の線材７と、下側の受具２を構成する下側の線材７とを挟持する連結具１１とを備えたものであり、前記連結具１１が、前記上下に重ね合わされた上側の受具２を構成する上側の線材７に対し、前記受具２の内部側から係合する上側の連結具本体１２と、下側の受具２を構成する下側の線材７に対し、前記受具２の外部側から係合する下側の連結具本体１２と、前記上側の線材７と下側の線材７とを挟持すべく、前記上側の連結具本体１２と下側の連結具本体１２とを相対的に引寄せるための引寄手段としてのボルト２１とを備えたものである。
【００２９】
したがって、線材の組付けにより構成された受具２同士を長手方向の適宜長において上下に重ね合わせ、次いで、上側の連結具本体１２及び下側の連結具本体１２をそれぞれ上側の受具２の線材７及び下側の受具２の線材７と係合し、ボルト２１及びナット２２で締付けて上側の受具２の線材７と下側の受具２の線材７とを挟持するだけの簡単な操作で両受具２の線材７同士を確実に連結することができる。その結果、受具２を切断することなく、簡単に長さ調整して、受具２同士を連結し、また、受具２の配設を所定の終端位置で終了させることができる。
【００３０】
また、ボルト２１及びナット２２による締付けによって上側の受具２の線材７と下側の受具２の線材７とが強く挟持されるので、均一かつ所要の連結強度を得ることができる。
【００３１】
ところで、上記各実施例における連結具は、受具２の載置部３の隣合う２本の縦筋６の線材７間に架設しているが、これに限られるものではなく、３本以上の縦筋６の線材７間に架設することもできる。
【００３２】
【発明の効果】
以上のように、請求項１、請求項２に記載の発明においては、複数の受具の線材同士を挟持するだけの簡単な操作で両受具の線材同士を連結することができる。その結果、受具を切断することなく、簡単に長さ調整して、受具同士を連結し、また、受具の配設を所定の終端位置で終了させることができる。
【００３３】
更に、請求項１、請求項２に記載の発明は、上側の連結具本体と下側の連結具本体との引寄せによって生ずる上側の線材及び下側の線材の変形を防止する変形防止部を備えたものである。したがって、特に、上側の連結具本体及び下側の連結具本体が引寄手段による締付けによって凹み変形するのを防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a connector for a wire / pipe material receiver constructed by assembling wires.
[0002]
[Prior art]
As a wiring / pipe material receiver, in addition to a ladder type in which a plurality of child girders are installed at appropriate intervals between a pair of left and right parent girders extending in the longitudinal direction, A mesh-type receiver is used. As shown in FIG. 3, this mesh-type receiver is formed by combining a plurality of wire rods 7 made of metal into a horizontal and vertical mesh shape as horizontal stripes 5 and vertical stripes 6, and welding the intersecting portions of the wire rods 7. Yes. The laying path in which the wiring / pipe material is laid is formed by connecting, in the length direction, receiving members 1 having a predetermined length formed by assembling the plurality of wire materials.
[0003]
The connection between the receivers is performed by connecting and receiving the receivers 2 in order from both the one end side and the other end side, and finally connecting the receivers 2 at both ends. Here, as a means for connecting the receivers 2 to each other, for example, a connector 31 described in German Patent Application No. 2036325 is disclosed. As shown in FIG. 15, the connecting tool 31 is configured to hold the wire rods by pulling the two metal fittings 32 and the metal fittings 33 with screws 34, and the wire rods of the horizontal bars 5 at the ends of the two holders 2. The receivers 2 can be connected to each other by placing the two wires 7 side by side and sandwiching the two wire rods 7 by the sandwiching bracket 32 and the sandwiching bracket 33 of the connector 31.
[0004]
Similarly, when the receivers are sequentially connected and installed, and the placement of the receivers is finished at a predetermined position, for example, a position just near the wall, the ends of the receivers 2 are similarly connected to each other, for example, 2 It can be connected by means of the connecting tool 31 comprising a single sheet metal fitting 32, a metal fitting 33 and a screw 34.
[0005]
[Problems to be solved by the invention]
However, in order to form a wiring / piping material laying path, the receivers 2 are connected in order from both the one end side and the other end side, and finally the receivers 2 at both ends are finally connected. In addition, when the receiving devices are sequentially connected and installed, and the placement of the receiving devices is finished at a predetermined position, for example, at a position close to the wall, the receiving device 2 at the terminal end is usually just in dimension. It doesn't end in length. For this reason, after adjusting the length by cutting a part of the receiving tool 2 at either one end to a predetermined length, both the receiving tools 2 must be connected with the connecting tool 31 or the like. However, it is extremely troublesome and difficult to cut a part of the receiver assembled with these wires and adjust the length.
[0006]
Therefore, the present invention can easily adjust the length without cutting the receiver configured by assembling the wire, and connect the receivers to each other. An object of the present invention is to provide a connector for a wiring / piping material receptacle that can be terminated at a terminal position.

And a deformation preventing member for preventing deformation of the upper wire and the lower wire. It is intended.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to FIGS.
In the figure, a plurality of receivers 2 are connected and fixed by a connector 11 in order to form a wiring / pipe material laying path linearly in the longitudinal direction, and these receivers 2 and the connector 11 connect the wire. The connecting device 1 is configured.
[0010]
The receiving device 2 is composed of a placement portion 3 on which the wiring / piping material C is placed, and a standing portion 4 standing on both sides of the placement portion 3, and is orthogonal to the longitudinal direction, that is, the installation direction. It is formed by assembling the horizontal streak 5 arranged in the direction in which the vertical streak is arranged and the vertical streak 6 arranged in the longitudinal direction below the horizontal streak 5 in the vertical and horizontal directions. The horizontal bars 5 and the vertical bars 6 are formed of a wire rod 7 made of a metal round bar, a square bar, a bar having a substantially oval cross section, etc., and these wire rods 7 are assembled in a mesh shape by welding. .
[0011]
In the receiver 2, as shown in FIG. 4, the wire rod 7 of the horizontal bar 5 is formed with a stepped portion 5a bent substantially at the middle portion of the standing portion 4, and the lower portion of the stepped portion 5a is in relation to the upper end portion. Thus, the dimension of the step b projects inside the support 2. Further, in the fusion part 8 where the wire 7 of the horizontal bar 5 and the wire 7a of the vertical bar 6 installed in the installation direction at the upper end of the standing part 4 are welded, the wire 7 of the horizontal bar 5 and the wire of the vertical bar 6 are provided. Due to the elution of both 7a, the contact surface between the wire 7 of the horizontal bar 5 and the wire 7a of the vertical bar 6 is indented into the inner side of the support 2 by the elution margin a. Here, the step b is formed at least larger than the elution margin a, that is, b> a. Therefore, in FIG. 4, L1 is a distance dimension inside the wire 7 a in the fusion part 8, and L2 is a distance dimension outside the standing part 4 of the wire 7 in the horizontal line 5. Is established.
[0012]
Here, if the step portion 5a is not formed on the wire rod 7 of the horizontal bar 5 in the standing part 4, b = 0, so that L1 <L2 and the horizontal bar 5 of the one receiver 2 The wire 7 and the wire 7 a at the upper end of the upright portion 4 of the other receiving device 2 interfere with each other, and the one receiving device 2 cannot be fitted into the other receiving device 2.

However, in the receiving device 2 of the present embodiment, a stepped portion 5a with b> a is formed, the relationship of L1> L2 is established, and the upright portion 4 is provided with only the upper end wire 7a. ing. For this reason, when the receiving members 2 are superposed one above the other in a state where the wire 7 of the horizontal bar 5 of one receiver 2 is shifted in the laying direction with respect to the wire 7 of the horizontal bar 5 of the other receiver 2, The wire rod 7 of the horizontal bars 5 in the receiver 2 can be fitted between the wire rods 7 a without interfering with the wire rod 7 a at the upper end of the standing portion 4 in the other receiver 2. Therefore, as shown in FIG. 5, one receiver 2 and the other receiver 2 can be overlapped with each other in the vertical direction.
[0014]
Next, the connector 11 includes an upper connector body 12 that engages with the wire 7 of the upper vertical stripe 6 in the receiver 2 disposed on the upper side, and a lower side in the receiver 2 disposed on the lower side. The lower connector main body 12 that engages with the wire 7 of the vertical bars 6 and the upper connector main body 12 and the lower connector main body 12 are attracted to draw them relatively in the vertical direction. It is comprised with the volt | bolt 21 used as a means.
[0015]
As shown in FIG. 6, the connector main body 12 is formed by bending a metal rectangular flat plate by press work, and substantially engaging portions 14 are formed at both ends of the flat plate portion 13. Further, an insertion hole 15 through which the bolt 21 is inserted is provided in the central portion of the flat plate portion 13, and reinforcing ribs 16 are formed on both sides thereof. The interval between the pair of engaging portions 14 formed at both ends of the flat plate portion 13 is formed to be equal to the interval between the adjacent vertical stripes 6 in the mounting portion 3 of the receiving device 2. It does not move in the direction orthogonal to the wire 7. The engaging portion 14 is formed in a substantially mountain shape, but may be formed in an arc shape corresponding to the outer shape of the wire 7.
[0016]
Further, in order to prevent deformation of the connector body 12 between the upper connector body 12 and the lower connector body 12 when the bolt 21 and the nut 22 are tightened, A deformation preventing member 23 made of a wire having a predetermined length is interposed.
[0017]
Next, in order to adjust the lengths of the receiving members at the ends connected in order from both directions by the connecting device of the present embodiment configured as described above, or to arrange the receiving devices at a predetermined end position. In order to complete the process, a method for connecting the receiving members to each other will be described.
[0018]
First, without cutting the receiving device 2 at the end of the laying path, a part of one receiving device 2 is accommodated from above on the inner side of the other receiving device, and the appropriate lengths in the longitudinal direction are overlapped vertically. Next, two lower connector main bodies 12 from the outside of the receiver 2 are arranged under the lower receiver 2, and the engaging portion 14 of the connector main body 12 is mounted on the receiver 2. Engage with the wire rods 7 of the two vertical bars 6 in the mounting portion 3, and in this state, face the lower connector body 12 and on the upper receiver 2 from the inner side of the receiver 2. Two upper connector main bodies 12 are arranged, and the engaging portions 14 of the connector main body 12 are engaged with the wires 7 of the two vertical bars 6 in the placement portion 3 of the receiving device 2. Next, the bolt 21 is inserted into the insertion hole 15 of both the connector main bodies 12, and the nut 22 is screwed and tightened. In addition, if at least one insertion hole 15 of the upper and lower connector main bodies 12 is a screw hole, it can be tightened only by the bolt 21, and the nut 22 is not necessary.
[0019]
Here, as shown in FIGS. 1 and 2, the vertical stripe 6 of the placement portion 3 of the upper receiving tool 2 is placed on only one horizontal stripe 5 in the placement portion 3 of the lower receiving tool 2. In the case where it is placed, it is tilted with one horizontal bar 5 in the lower receiving tool 2 as a fulcrum, and the upper and lower two connecting tool bodies 12 are also tightened in a tilted state. Then, the lower surface of the head of the bolt 21 is locally strongly in contact with the flat plate portion 13 of the upper connector main body 12, and the flat plate portion 13 of the connector main body 12 is recessed and deformed. Therefore, before tightening with the bolt 21 and the nut 22, it is necessary to interpose the deformation preventing member 23 in advance below the vertical bars 6 of the placing portion 3 in the upper receiving tool 2. For example, the deformation preventing member 23 can be formed of a wire having the same diameter and a predetermined length as the wire 7 of the transverse bar 5 of the lower receiving tool 2. The deformation preventing member 23 corresponds to a deformation preventing portion in claims.
[0020]
In this way, by tightening the bolt 21 and the nut 22, the wire 7 of the upper receiver 2 and the wire 7 of the lower receiver 2 are attracted relatively strongly in the vertical direction, and the wire of the longitudinal bars 6. 7 and the engaging part 14 of the connector main body 12, a sliding resistance acts, so that both the receivers 2 are connected and fixed at predetermined positions.
[0021]
By the way, as shown in FIG.7 and FIG.8, the said connector main body 12 may form the protrusion 13a in a part of flat plate part 13. As shown in FIG. The projecting piece 13a can be formed by cutting a portion of the flat plate portion 13 into a substantially U shape and then bending the substantially U plate portion at a right angle to the side facing the other connector body 12. . The height of the protrusion 13a is such that when the pair of upper and lower connector bodies 12 are pulled together by bolts 21 and nuts 22 and the tips of the protrusions 13a come into contact with the mating flat plate portion 13, the two connector bodies 12 The flat plate portion 13 is formed in such a size as to be in a substantially parallel state.
[0022]
When the connector main body 12 having the protrusion 13a is used, when the pair of upper and lower connector main bodies 12 are drawn to bring the flat plate portion 13 into a substantially parallel state, the tips of both the protrusions 13a are mutually connected. It is possible to prevent further tightening of the bolt 21 and the nut 22 by abutting against the mating flat plate portion 13. For this reason, the deformation | transformation prevention member 23 formed with the wire rod prevents the dent deformation | transformation of the center part of the flat plate part 13 by clamping | tightening of the volt | bolt 21 and the nut 22 similarly to the case where it interposes between a pair of connector main body 12. Can do. Note that the protruding piece 13a of the flat plate portion 13 also corresponds to the deformation preventing portion of the claims.
[0023]
Next, modified examples of the connector 11 are shown in FIGS.
In FIG. 9, a padding material 17 is attached to the surface of the engaging portion 14 of the connector main body 12 that contacts the wire 7. In the case of this embodiment, the sliding resistance between the engaging portion 14 of the connector main body 12 and the wire 7 is increased in a state where the upper receiver 2 and the lower receiver 2 are connected by the connector 11, The connecting tool 11 is further prevented from moving in the axial direction of the longitudinal bars 6 with respect to the receiving tool 2, and the connecting tool 11 is stably held at a fixed position of the receiving tool 2. In addition to the packing 17, a resin coating or the like may be applied to the surface of the engaging portion 14 of the connector main body 12 that contacts the wire 7.
[0024]
Next, in FIG. 10, the connector main body 12 is formed of a metal leaf spring material, the central portions bulge out from each other, and the whole is bent in an arc shape. In the case of this embodiment, a bolt 21 is inserted into the insertion hole 15 of the connector 11 and a nut 22 is screwed and tightened to resist the resilience of the connector body 12 as shown in FIG. As a result, the central portions are close to each other and are in a substantially parallel state. In this state, since the elastic force to return the central part of the connector main body 12 acts outwardly, the engaging portions 14 provided at both ends of the connector main body 12 are, conversely, It works in the direction of pressing the wire 7. As a result, the sliding resistance between the engaging portion 14 of the connector main body 12 and the wire 7 increases, and the connector 11 is connected to the shaft of the vertical bar 6 with respect to the receiver 2 as in the case of FIG. It is further prevented from moving in the direction, and the connector 11 is stably held at a fixed position of the receiver 2.
[0025]
In FIG. 12, the connector main body 12 of the connector 11 has the horizontal stripes 5 of the mounting portion 3 of the receiving device 2 on either one of the sides different from the two sides of the flat plate portion 13 where the engaging portions 14 are formed. A shift preventing portion 18 having a substantially mountain-shaped cross section that engages with the wire 7 is integrally formed. In the case of this embodiment, the displacement preventing portion 18 is engaged with the wire 7 of the transverse bar 5 in the placement portion 3 of the receiving device 2, so that the engaging portion of the connector main body 12 shown in FIGS. 9 to 11 is used. It is possible to prevent the connector 11 from moving in the axial direction of the longitudinal bars 6 with respect to the receiver 2 without depending on the sliding resistance between the wire 14 and the wire 7.
[0026]
Further, in FIG. 13, the connector main body 12 is provided with a step at the opposite end portion of the engaging portion 14 having one of the cross-sectional mountain shapes in the flat plate portion 13, and extends to the side to provide the longitudinal bars 6 of the receiving device 2. A flat plate-like contact portion 19 that is in contact with is integrally formed. In this embodiment, when the bolt 21 and the nut 22 are tightened, the engaging portion 14 and the abutting portion 19 of the connector main body 12 abut on the wire rod 7 of the adjacent vertical streak 6 in the receiver 2, and the upper side The wire 7 and the lower wire 7 are clamped by the connector 11, and the upper receiver 2 and the lower receiver 2 are connected and fixed. In particular, in this embodiment, since the contact portion 19 of the connector main body 12 is formed in a flat plate shape, the connector main body can be used even when the interval between the wires 7 of the adjacent vertical bars 6 in the receiver 2 is different. 12 engaging portions 14 and abutting portions 19 abut against the wire rod 7 of the longitudinal bars 6. For this reason, it can be connected correspondingly to various sizes of receiving devices 2 in which the distance between the wires 7 of the vertical bars 6 is different.
[0027]
In FIG. 14, the shift prevention portion of FIG. 12 is provided on one side of the flat plate portion 13 of the connector main body 12 of FIG. 13 where the engagement portion 14 and the contact portion 19 are different from the two sides. The same shift prevention part 18 as 18 is provided integrally. Therefore, in the embodiment shown in FIG. 14, it is possible to freely connect to the receiving devices 2 of various sizes in which the intervals of the wire rods 7 of the longitudinal bars 6 are different, and to connect the receiving device 2 to the receiving device 2. Can be prevented from moving in the axial direction of the longitudinal bars 6 and the connector 11 can be held stably.
