Description

【０００１】
【発明の属する技術分野】
本発明は、建築物内の壁の裏側に取り付けられ、コンセント等の配線器具が取り付けられる配線用装置及び配線用枠体に関するものである。
【０００２】
【従来の技術】
従来より、スイッチやコンセント等の配線器具を室内に臨ませて壁に設置するため、その壁裏には配線器具取付具として有底四角箱状をなす配線用ボックスが設置されている。ところが、近年では、Ｃ型鋼等の軽量間柱の前後に石膏ボードが立設されて形成される壁が多くなってきている。このような壁は、石膏ボード間にコンクリートが打設されないため、コンクリート壁と異なりコンクリートの打設圧に対する配線器具取付具の耐圧性等を考慮する必要がない。そのため、配線用ボックスの代わりに枠状に形成された配線用枠体が配線器具取付具として使用されている。
【０００３】
この配線用枠体としては特開平７−２１２９３号公報に開示されるものが知られている。この配線用枠体は、金属板により略四角枠状をなす前板部と、その前板部の両側部からそれぞれ同一方向へ延設された側板部とより平面略コ字状に形成されている。前記前板部の中央部には配線器具を挿入可能な装着孔が形成され、その装着孔を形成する金属板の内周にはビス孔が形成されている。
【０００４】
そして、配線用枠体が、その前板部の前面が間柱の前面と略面一となるように一方の側板部が間柱に取り付け固定された状態で、その配線用枠体の前面及び後面側に石膏ボードが立設されて壁が形成される。さらに、壁形成後、石膏ボードの表側に形成された透孔から装着孔の前記ビス孔に配線器具を保持した配線器具保持枠をビス止めして、配線器具が配線用枠体に取り付けられるとともに、石膏ボード、即ち壁に配線器具が設置される。
【０００５】
【発明が解決しようとする課題】
ところが、上記従来の配線用枠体はその一方の側板部のみが間柱に固定され、前板部及び他方の側板部は間柱等に固定されていないため、その前板部及び他方の側板部の応力等に対する強度は一方の側板部よりも低くなっている。そのため、壁形成後、配線器具に種々の応力が作用し、その応力が配線器具からビス孔に集中的に作用したとき、その応力により前板部の装着孔の周縁部等が変形してしまうおそれがあった。
【０００６】
そして、前板部が変形してしまうと、その配線用枠体に取り付けられた配線器具が傾いたり、ぐらついたりして配線器具を配線用枠体に安定した状態で取り付けることができなくなるという問題があった。また、配線用枠体は一方の側板部が間柱に固定されるため、その配線用枠体に取り付けられる配線器具は、間柱の近傍位置にしか設置することができず、配線器具を壁面の任意の位置に設置することができないという問題があった。
【０００７】
本発明は、上記従来技術に存在する問題点に着目してなされたものである。その目的とするところは、配線用枠体に作用する応力による同配線用枠体の変形を防止して、その配線用枠体に配線器具を安定した状態で取り付けることができるとともに、配線器具を壁の任意の位置に設置することができる配線用装置及び配線用枠体を提供することにある。
【０００８】
【課題を解決するための手段】
上記問題点を解決するために、請求項１に記載の発明は、建築物内の上下方向に間隔をおいて横方向に延びるべく壁内に立設される構築物に固定される固定バー材と、四角枠状をなし、その開口から挿入された配線器具を取り付け可能に形成された枠状部及び当該枠状部に一体形成され、前記固定バー材に前記枠状部を支持可能とする支持部を備えた配線用枠体とよりなる配線用装置において、前記枠状部の上部側及び下部側に配線器具を取付可能とする取付部を設けると共に、当該枠状部の左右側部から前記支持部としての一対の側板部を枠状部の後方へ延設して、前記配線用枠体を平面略コ字状に形成し、前記両側板部の上下両部には、前記固定バー材が前記枠状部の上部側及び下部側に沿ってそれぞれ挿通可能に形成される固定バー材貫通部を備え、上下で挿通された前記固定バー材に両側板部を支持させて当該両固定バー材に枠状部を支持させることにより、両固定バー材による前記枠状部に作用する応力の支持を可能に形成したことを要旨とする。

【００１４】
請求項７に記載の発明は、四角枠状をなし、その開口から挿入された配線器具を取り付け可能に形成された枠状部及び当該枠状部に一体形成され、建築物の壁内に固定される固定バー材に前記枠状部を支持可能とする支持部を備えた配線用枠体において、前記枠状部の上部側及び下部側に配線器具を取付可能とする取付部を設けると共に、当該枠状部の左右側部から前記支持部としての一対の側板部を枠状部の後方へ延設して平面略コ字状に形成し、前記両側板部の上下両部には、前記固定バー材が前記枠状部の上部側及び下部側に沿ってそれぞれ挿通可能に形成された固定バー材貫通部を備え、上下で挿通される前記固定バー材に両側板部を支持させて当該両固定バー材に枠状部を支持させることにより、両固定バー材による前記枠状部に作用する応力の支持を可能に形成したことを要旨とする。
【００１８】
【発明の実施の形態】
以下、本発明を具体化した配線用装置１０及び配線用枠体１１の一実施形態を図１〜図６に従って説明する。なお、本実施形態において、図１における上下左右を配線用装置１０及び配線用枠体１１の上下左右とする。配線用装置１０は、配線用枠体１１と、建築物内の壁を構築すべく立設された構築物としての間柱２１に固定され、外周面に雄ネジが螺刻された金属棒よりなる固定バー材１２とよりなるものである。
【００１９】
まず、金属板製の配線用枠体１１から説明する。図１に示すように、配線用枠体１１は枠状をなし、その開口から挿入された配線器具（図示せず）を取り付け可能に形成された枠状部１３を備えている。さらに、配線用枠体１１は前記枠状部１３の相対向する左右側部に一体形成され、前記固定バー材１２に前記枠状部１３を支持可能とする支持部としての第１及び第２側板部１４，１５を備えている。
【００２０】
具体的には、配線用枠体１１は四角枠状をなす枠状部１３と、その枠状部１３の左右両側部をそれぞれ上下方向に沿って同一方向へ折り曲げて、枠状部１３の後方へ延設された第１及び第２側板部１４，１５とより平面略コ字状に形成されている。前記枠状部１３の上下両部には、それぞれ枠状部１３の左右方向に沿って複数箇所に切り欠き孔１３ａが形成されている。枠状部１３の中央部には、縦長長方形状をなす装着孔１６が形成され、その装着孔１６の内周面の上下各中央部にはそれぞれ配線器具（図示せず）を取付可能な取付部１７ａが装着孔１６内方へ延設されているとともに、その取付部１７ａにはそれぞれビス孔１７が形成されている。
【００２１】
また、装着孔１６の左側内周にはビス保持部１８が装着孔１６内方へ延設され、そのビス保持部１８には、上下及び左右にそれぞれ相対向する突片１８ａが突設されている。そして、図３に示すように、ビス保持部１８は、上下一対の突片１８ａと左側の突片１８ａとの間、及び上下一対の突片１８ａと右側の突片１８ａとの間に、それぞれ配線器具（図示せず）を配線用枠体１１に取り付けるためのビス１９を保持可能に構成されている。なお、このビス保持部１８は装着孔１６の内周面から切り離して枠状部１３から除去することができるように構成されている。
【００２２】
図１に示すように、前記第１側板部１４は枠状部１３に対して略直交する状態で枠状部１３の左側縁の上下方向に沿って延びるように形成されている。そして、図２に示すように、第１側板部１４の上下両側部の前後２箇所には、それぞれ固定バー材１２が貫通可能に形成された固定バー材貫通部２０が形成されている。第１側板部１４の前側の前記固定バー材貫通部２０は、第１側板部１４に略長孔状に貫通形成された貫通孔２０ａと、金属板を切り欠いてその貫通孔２０ａの内方へ延設された固定手段としての固定片２０ｂとから構成されている。
【００２３】
第１側板部１４の前側に形成された前記固定バー材貫通部２０は、第１側板部１４の前後方向に沿って固定バー材１２を３つの異なる位置でそれぞれ挿通、固定可能とすべく貫通孔２０ａの周形状が３つの円弧を組み合わせた形状に形成されている。即ち、固定バー材貫通部２０には、枠状部１３の前面から固定バー材貫通部２０に固定される固定バー材１２までの距離を３段階に調整できるように固定バー材１２の挿通位置が３箇所に形成されている。また、前記固定片２０ｂは貫通孔２０ａに固定バー材１２が挿通されたとき、第１側板部１４の外方へ弾性変形するとともに、自身の弾性力により元に戻り固定バー材１２を押圧するように構成されている。第１側板部１４の後側に形成された固定バー材貫通部２０は固定バー材１２の挿通位置が１箇所だけ形成された貫通孔２０ａと固定片２０ｂとより形成されている。
【００２４】
一方、図１に示すように、前記第２側板部１５は、枠状部１３の上下方向に沿って後側に向かうに従い外方へ広がるように曲げ形成されている。また、第２側板部１５の上下両側部の前側には、それぞれ前記第１側板部１４の前側の貫通孔２０ａと同じ構成、即ち固定バー材１２の挿通位置が３箇所に形成された貫通孔２０ａが形成されている。第１側板部１４の固定バー材貫通部２０の各貫通孔２０ａと、第２側板部１５の各貫通孔２０ａはそれぞれ相対向する位置に形成されている。また、第２側板部１５の後部にも、第１側板部１４の後側の固定バー材貫通部２０と同様の構成の貫通孔２０ａが形成されている。
【００２５】
図１及び図３に示すように、相対向する貫通孔２０ａの挿通位置に固定バー材１２が挿通されたとき、各固定バー材１２は枠状部１３の上下各側部の左右方向に沿って平行に延びるように構成されている。また、固定バー材貫通部２０及び貫通孔２０ａはそれぞれ前記ビス孔１７より外方側、即ち上部側のビス孔１７より上側、下部側のビス孔１７より下側に形成され、各挿通位置に挿通された固定バー材１２がビス孔１７より外方を通過するように構成されている。そして、第１及び第２側板部１４，１５の相対向する貫通孔２０ａに固定バー材１２を挿通することにより、固定バー材１２に第１及び第２側板部１４，１５を貫通支持させて固定バー材１２に枠状部１３を支持させることができる。また、固定バー材貫通部２０により固定バー材１２に第１側板部１４を固定することができる。
【００２６】
第１及び第２側板部１４，１５の相対向する貫通孔２０ａのうち最も前側の貫通孔２０ａの挿通位置に固定バー材１２を挿通して貫通させる。さらに、その固定バー材１２の端部を幅方向の長さが４０ｍｍの間柱２１の幅方向の長さの中央に固定すると枠状部１３の前面とその間柱２１の前面とが面一となるように設定されている。そして、前記最も前側の貫通孔２０ａの挿通位置より１つ後側の貫通孔２０ａの挿通位置に固定バー材１２が挿通されると、４５ｍｍの間柱２１と対応し、さらに１つ後側の貫通孔２０ａの挿通位置に固定バー材１２が挿通されると、５０ｍｍの間柱２１に対応するように構成されている。第１側板部１４及び第２側板部１５の最後端に形成された貫通孔２０ａに固定バー材１２が挿通された場合は、６５ｍｍの間柱２１に対応するように構成されている。
【００２７】
また、図１に示すように、第２側板部１５において、上下両貫通孔２０ａの内側にはそれぞれドライバ孔２２が形成され、図２に示すように、第１側板部１４において、上下両固定バー材貫通部２０の内側にはそれぞれねじ孔２３が形成されている。そして、ねじ孔２３から木ねじ（図示せず）等を柱等にねじ込む際に、前記ドライバ孔２２からドライバを挿通して木ネジのねじ込み作業を行うことができるようになっている。
【００２８】
次に、上記構成の配線用装置１０を使用した配線器具の取付作業を作用とともに説明する。
配線用枠体１１は、枠状部１３より第２側板部１５が外方へ広がるように形成されている。そのため、配線用枠体１１を保管するために、複数の配線用枠体１１同士を重ね合わせたとき、その重ね合わせが容易に行われる。
【００２９】
さて、建築物内に立設された間柱２１の幅方向の長さに対応させて上下両貫通孔２０ａの挿通位置を選択する。続いて、２本の固定バー材１２をそれぞれ第２側板部１５の前記挿通位置、次いで第２側板部１５の挿通位置と相対向する第１側板部１４の挿通位置に挿通する。なお、２本の固定バー材１２はそれぞれ第１側板部１４の前記挿通位置、次いで第１側板部１４の挿通位置と相対向する第２側板部１５の挿通位置に挿通してもよい。
【００３０】
続いて、図１に示すように、それら一対の固定バー材１２を上下方向に間隔をおいて横方向へ延びるように配置し、固定バー材１２の両端を間柱２１の幅方向の中央部を貫通させる。さらに、固定バー材１２の各端部にナット１２ａが螺合されて各間柱２１に固定バー材１２の端部が固定されるとともに、間柱２１間に固定バー材１２が架設される。すると、固定バー材１２に第１及び第２側板部１４，１５が支持されることにより枠状部１３が固定バー材１２に支持され、同固定バー材１２に配線用枠体１１が支持される。
【００３１】
次に、配線用枠体１１を固定バー材１２の長さ方向に沿って移動させ、固定バー材１２の長さ方向における所望する位置に配線用枠体１１を配置する。固定バー材１２における配線用枠体１１の位置が決定した後、固定バー材１２の貫通孔２０ａへの挿通により、固定バー材１２の挿通方向へ変形した固定片２０ｂの先端側をドライバ等の工具により元に戻す。そして、その固定片２０ｂが自身の弾性力により固定バー材１２が挿通される前の状態に戻ろうとするため、固定バー材１２の外周面はその固定片２０ｂにより押圧される。
【００３２】
すると、固定バー材１２は固定片２０ｂの先端縁と貫通孔２０ａの内周縁とにより挟持されて固定バー材１２に第１側板部１４が固定され、固定バー材１２に沿った配線用枠体１１の移動が規制される。間柱２１に固定された固定バー材１２に第１側板部１４が固定された状態で、配線用枠体１１が間柱２１間に設置されるとともに、配線用装置１０が構成される。第１側板部１４は、間柱２１に固定された２本の固定バー材１２に固定され、第２側板部１５は固定バー材１２に支持されているため、その第１及び第２側板部１４，１５に支持された枠状部１３は、固定バー材１２に移動不能に支持されている。
【００３３】
さて、配線用枠体１１が間柱２１間に設置された状態において、図３及び図４に示すように、ケーブル２４が挿通された電線管２５をバインド線２６により枠状部１３の上縁部に結束する。このとき、バインド線２６は切り欠き孔１３ａに挿通、結束することができるため、前記結束作業の簡易化が図られる。そして、前記ケーブル２４を配線用枠体１１の装着孔１６内に位置するように引き出しておく。
【００３４】
次いで、図５に示すように、間柱２１の前面及び後面側に石膏ボード（図５では前側の石膏ボードのみ図示）等の壁材２７が立設され、その壁材２７の間に配線用枠体１１が配置される。さて、図６に示すように、配線用枠体１１に配線器具２９を取り付けるには、まず、配線用枠体１１の装着孔１６に対応する透孔２８を壁材２７に穿設し、前記ケーブル２４を壁材２７の表側に引き出す。続いて、そのケーブル２４に配線器具２９を接続し、その配線器具２９を保持枠３０に保持させる。次いで、ビス保持部１８からビス１９を取り出し、そのビス１９を保持枠３０から前記ビス孔１７に挿通、螺合して保持枠３０を介して配線器具２９を配線用枠体１１に取り付ける。
【００３５】
配線器具２９が装着孔１６から配線用枠体１１内部へ挿入され、ビス１９がビス孔１７に挿通されるとき、２本の固定バー材１２はそれぞれビス孔１７より外方に位置するため、固定バー材１２により前記挿入作業及び挿通、螺合作業が妨げられない。その結果、間柱２１間に設置された配線用枠体１１に配線器具２９が取り付けられるとともに、壁材２７の前面に配線器具２９が設置される。
【００３６】
配線用枠体１１に対する配線器具２９の取付状態において、配線器具２９に応力が作用したとき、その応力はビス１９からビス孔１７が形成された枠状部１３の上下両部に作用する。このとき、枠状部１３は第１及び第２側板部１４，１５を介して固定バー材１２に支持されているため、枠状部１３に作用した応力は固定バー材１２に支持される。従って、枠状部１３の上下両側部に作用する応力により枠状部１３が変形しにくくなる。
【００３７】
上記実施形態によれば、以下のような特徴を得ることができる。
（１）間柱２１に固定された２本の固定バー材１２に第１側板部１４を固定するとともに、第１側板部１４及び第２側板部１５の上下両部を固定バー材１２に支持させ、枠状部１３を固定バー材１２に支持させた。そのため、枠状部１３に作用する応力は、その枠状部１３に一体形成された第１及び第２側板部１４，１５に支持され、さらに、固定バー材１２に支持される。従って、配線用枠体１１の一側部のみが間柱２１に固定され、中央部から他方側は支持されていなかった従来と異なり、枠状部１３における応力に対する強度が向上し、応力により枠状部１３、即ち配線用枠体１１が変形する不具合をなくすことができる。その結果、配線用枠体１１に取り付けられた配線器具２９がぐらついたり、傾いたりする不具合をなくして配線器具２９を配線用枠体１１に安定した状態で取り付けることができる。
【００３８】
（２）固定バー材１２の長さ方向の所望する位置に配線用枠体１１を配置することができ、間柱２１間において、配線器具２９を取り付ける位置を調整することができる。従って、間柱２１の近傍位置にしか配線器具２９を設置することができなかった従来と異なり、室内のデザインやレイアウト等に対応した位置に配線器具２９を設置することができる。
【００３９】
（３）間柱２１に固定された２本の固定バー材１２に対して第１側板部１４を固定した状態で、第１側板部１４及び第２側板部１５の上下両部を固定バー材１２に支持させた。そのため、金属板をプレス成形して形成された配線用枠体１１の強度を向上させることができ、金属材料製の配線用ボックスを製造する場合と異なり、材料の節約を図ることができる。
【００４０】
（４）枠状部１３には第１及び第２側板部１４，１５が一体形成されているため、それら第１及び第２側板部１４，１５により特に枠状部１３の左右側部の強度を向上させることができる。
【００４１】
（５）第１側板部１４及び第２側板部１５は上下両部で固定バー材１２に支持されているため、第１及び第２側板部１４，１５が１本の固定バー材１２に支持されている場合と比較して、枠状部１３に作用する応力を強く支持することができ、応力に対する強度を高めることができる。
【００４２】
（６）固定バー材１２は上部側のビス孔１７より上側を通過し、下部側のビス孔１７の下側を通過するため、固定バー材１２が配線器具２９の装着孔１６内への挿入作業の妨げやビス１９のビス孔１７への挿通、螺合の妨げになるといった不具合をなくすことができる。
【００４３】
（７）貫通孔２０ａの各挿通位置から枠状部１３の前面までの距離は、各種サイズの間柱２１の幅方向の中央からその間柱２１の前面までの距離と同じに設定されている。従って、間柱２１の前面と配線用枠体１１の前面とが面一となるように第１及び第２側板部１４，１５における固定バー材１２の挿通位置を調整する場合と比較して、配線用枠体１１の間柱２１への取付作業を速やかに行うことができる。
【００４４】
（８）貫通孔２０ａの挿通位置を間柱２１の幅方向の長さに対応させて選択することにより、固定バー材１２の間柱２１に対する固定位置を変更することなく配線用枠体１１の前面と間柱２１の前面とを面一にすることができる。
【００４５】
（９）固定片２０ｂにより固定バー材１２の長さ方向に沿って配線用枠体１１が移動するのを防止して、その配線用枠体１１に取り付けられた配線器具２９の移動を防止することができる。また、第１側板部１４が固定バー材１２に固定されることにより、固定バー材１２に第１側板部１４を効果的に支持させることができる。
【００４６】
（１０）固定片２０ｂは第１側板部１４を切り欠いて形成され、金属材料の弾性力を利用して固定バー材１２を第１側板部１４に固定している。そのため、固定バー材１２の固定手段を配線用枠体１１とは別体に設ける場合と比較して配線用枠体１１及び配線用装置１０の製造コストの低減に寄与することができる。
【００４７】
なお、上記実施形態は以下のように変更してもよい。
・固定片２０ｂを省略するとともに、固定バー材１２の断面形状に対応した貫通孔２０ａを形成し、その貫通孔２０ａの内周縁をゴム材料により被覆して固定手段としてもよい。このように構成した場合、貫通孔２０ａに挿通された固定バー材１２の外周面にゴム材料が接触することにより、固定バー材１２外周面に対する摩擦力が大きくなり、第１側板部１４を固定バー材１２に固定することができる。
【００４８】
・また、固定片２０ｂを省略するとともに、貫通孔２０ａの内周縁から内方へ延びる複数の規制片を延設し、その規制片を固定手段としてもよい。このように構成した場合、貫通孔２０ａに固定バー材１２を挿通したとき、規制片が固定バー材１２の外周面に係合するため、その規制片により第１側板部１４を固定バー材１２に固定することができる。
【００４９】
・さらに、固定片２０ｂを省略するとともに、固定バー材１２の断面形状に対応した貫通孔２０ａを形成し、固定バー材１２の長さ方向に沿って配線用枠体１１の位置を調整した後、所望する位置で第１及び第２側板部１４，１５のうちの少なくともいずれか一方をナットで挟持して、そのナットを固定手段としてもよい。
【００５０】
・第１側板部１４における固定バー材貫通部２０及び第２側板部１５における貫通孔２０ａを１箇所だけとしてもよく、その固定バー材貫通部２０及び貫通孔２０ａに固定バー材１２が挿通されたとき、枠状部１３の前面と間柱２１の前面とが面一又は非面一になるようにしてもよい。また、貫通孔２０ａの挿通位置を２箇所、３箇所又は５箇所以上形成して、２種類、３種類又は５種類以上の間柱２１の前面と面一となるように挿通位置を調整して形成してもよい。
【００５１】
・固定バー材１２が各ビス孔１７の裏側又はビス孔１７より配線用枠体１１の内方側を通過するように固定バー材貫通部２０及び貫通孔２０ａを形成してもよい。
【００５２】
・第１及び第２側板部１４，１５の上下方向の任意の位置に間隔をおいて２本の固定バー材１２を貫通させてもよい。また、１本の固定バー材１２をコ字状となるように折り返し、その１本の固定バー材１２の相対向する折り返し部分を第１及び第２側板部１４，１５を貫通させてもよい。
【００５３】
・第１及び第２側板部１４，１５に１本又は３本以上の固定バー材１２を挿通して、第１及び第２側板部１４，１５を支持させてもよい。
・第１側板部１４の固定バー材貫通部２０に対向するように第２側板部１５に固定バー材貫通部２０を形成し、第１及び第２側板部１４，１５をそれぞれ固定バー材１２に固定してもよい。
【００５４】
・枠状部１３を丸枠状、三角枠状、五角枠状等に形成し、その枠状部１３に少なくとも第１側板部１４及び第２側板部１５を形成し、その第１及び第２側板部１４，１５に固定バー材１２を貫通させて固定バー材１２に第１及び第２側板部１４，１５を支持させてもよい。
【００５５】
・実施形態では、配線用枠体１１を金属材料により形成したが、配線用枠体１１を合成樹脂材料により形成してもよい。また、実施形態では間柱２１に固定バー材１２を貫通させ、その間柱２１に固定したが、Ｈ型鋼、木柱に固定バー材１２を固定し、その固定バー材１２に配線用枠体１１を支持させてもよい。
【００５６】

When a wood screw (not shown) or the like is screwed into the pillar or the like from the screw hole 23, the screw screw can be inserted through the driver hole 22 by inserting a screwdriver.
[0028]
Next, the installation work of the wiring apparatus using the wiring apparatus 10 having the above configuration will be described together with the operation.
The wiring frame 11 is formed such that the second side plate portion 15 extends outward from the frame-like portion 13. Therefore, when the plurality of wiring frame bodies 11 are overlapped to store the wiring frame bodies 11, the overlapping is easily performed.
[0029]
Now, the insertion positions of the upper and lower through holes 20a are selected in correspondence with the length in the width direction of the studs 21 erected in the building. Subsequently, the two fixed bar members 12 are respectively inserted into the insertion position of the second side plate portion 15 and then the insertion position of the first side plate portion 14 opposite to the insertion position of the second side plate portion 15. The two fixing bar members 12 may be inserted through the insertion position of the first side plate portion 14 and then the insertion position of the second side plate portion 15 opposite to the insertion position of the first side plate portion 14.
[0030]
Subsequently, as shown in FIG. 1, the pair of fixed bar members 12 are arranged so as to extend in the horizontal direction with a space in the vertical direction, and both ends of the fixed bar member 12 are arranged in the center portion in the width direction of the studs 21. To penetrate. Further, nuts 12 a are screwed into the respective end portions of the fixed bar member 12, and the end portions of the fixed bar member 12 are fixed to the respective intermediate columns 21, and the fixed bar member 12 is installed between the intermediate columns 21. Then, the first and second side plate portions 14 and 15 are supported by the fixed bar material 12, whereby the frame-shaped portion 13 is supported by the fixed bar material 12, and the wiring frame body 11 is supported by the fixed bar material 12. The
[0031]
Next, the wiring frame 11 is moved along the length direction of the fixed bar member 12, and the wiring frame 11 is arranged at a desired position in the length direction of the fixed bar member 12. After the position of the wiring frame 11 in the fixed bar material 12 is determined, the distal end side of the fixed piece 20b deformed in the insertion direction of the fixed bar material 12 by inserting the fixed bar material 12 into the through hole 20a Return to the original position with a tool. And since the fixed piece 20b tries to return to the state before the fixed bar member 12 is inserted by its own elastic force, the outer peripheral surface of the fixed bar member 12 is pressed by the fixed piece 20b.
[0032]
Then, the fixed bar material 12 is sandwiched between the tip edge of the fixed piece 20 b and the inner peripheral edge of the through hole 20 a, and the first side plate portion 14 is fixed to the fixed bar material 12, and the wiring frame along the fixed bar material 12 11 movement is restricted. In a state where the first side plate portion 14 is fixed to the fixed bar member 12 fixed to the intermediate pillar 21, the wiring frame 11 is installed between the intermediate pillars 21, and the wiring apparatus 10 is configured. Since the first side plate portion 14 is fixed to the two fixed bar members 12 fixed to the studs 21 and the second side plate portion 15 is supported by the fixed bar member 12, the first and second side plate portions 14 thereof. , 15 is supported by the fixed bar member 12 so as not to move.
[0033]
Now, in a state where the wiring frame 11 is installed between the studs 21, as shown in FIGS. 3 and 4, the conduit 25 through which the cable 24 is inserted is connected to the upper edge portion of the frame-like portion 13 by the bind wire 26. To unite. At this time, since the bind line 26 can be inserted and bundled into the cutout hole 13a, the bundling operation can be simplified. The cable 24 is pulled out so as to be positioned in the mounting hole 16 of the wiring frame 11.
[0034]
Next, as shown in FIG. 5, a wall material 27 such as a gypsum board (only the front gypsum board is shown in FIG. 5) is erected on the front surface and the rear surface side of the stud 21, and a wiring frame is provided between the wall materials 27. A body 11 is arranged. As shown in FIG. 6, in order to attach the wiring device 29 to the wiring frame 11, first, a through hole 28 corresponding to the mounting hole 16 of the wiring frame 11 is formed in the wall member 27, and the above-mentioned The cable 24 is pulled out to the front side of the wall material 27. Subsequently, the wiring device 29 is connected to the cable 24, and the wiring device 29 is held by the holding frame 30. Next, the screw 19 is taken out from the screw holding portion 18, and the screw 19 is inserted into the screw hole 17 from the holding frame 30 and screwed to attach the wiring device 29 to the wiring frame body 11 through the holding frame 30.
[0035]
When the wiring device 29 is inserted into the wiring frame 11 from the mounting hole 16 and the screw 19 is inserted into the screw hole 17, the two fixing bar members 12 are positioned outward from the screw hole 17. The fixing bar material 12 does not prevent the insertion operation, insertion, and screwing operation. As a result, the wiring device 29 is attached to the wiring frame 11 installed between the studs 21, and the wiring device 29 is installed on the front surface of the wall material 27.
[0036]
When stress is applied to the wiring device 29 in a state in which the wiring device 29 is attached to the wiring frame 11, the stress acts on both upper and lower portions of the frame-like portion 13 in which the screw holes 17 are formed from the screws 19. At this time, since the frame-like portion 13 is supported by the fixed bar member 12 via the first and second side plate portions 14 and 15, the stress acting on the frame-like portion 13 is supported by the fixed bar member 12. Accordingly, the frame-shaped portion 13 is not easily deformed by the stress acting on the upper and lower side portions of the frame-shaped portion 13.
[0037]
According to the above embodiment, the following features can be obtained.
(1) The first side plate portion 14 is fixed to the two fixed bar members 12 fixed to the spacers 21, and the upper and lower portions of the first side plate portion 14 and the second side plate portion 15 are supported by the fixed bar member 12. The frame portion 13 was supported on the fixed bar material 12. Therefore, the stress acting on the frame-like portion 13 is supported by the first and second side plate portions 14 and 15 formed integrally with the frame-like portion 13 and further supported by the fixed bar member 12. Therefore, unlike the conventional case where only one side portion of the wiring frame 11 is fixed to the spacer 21 and the other side is not supported from the center portion, the strength against the stress in the frame-like portion 13 is improved, and the frame shape is caused by the stress. The problem that the part 13, that is, the wiring frame 11, is deformed can be eliminated. As a result, the wiring device 29 attached to the wiring frame 11 can be attached to the wiring frame 11 in a stable state without the problem of wobbling or tilting.
[0038]
(2) The wiring frame 11 can be arranged at a desired position in the length direction of the fixed bar member 12, and the position where the wiring device 29 is attached between the studs 21 can be adjusted. Therefore, unlike the conventional case where the wiring device 29 can be installed only in the vicinity of the stud 21, the wiring device 29 can be installed at a position corresponding to the indoor design, layout, and the like.
[0039]
(3) In the state where the first side plate portion 14 is fixed to the two fixed bar members 12 fixed to the spacers 21, the upper and lower portions of the first side plate portion 14 and the second side plate portion 15 are fixed to the fixed bar member 12. Supported.
