Description

【０００１】
【発明の属する技術分野】
本発明は、例えばビルの如き建物の天井材を吊持する吊りボルトを利用して天井裏の空間に各種配管や電気配線を施す場合等、特に既設の垂直ボルトに係着して種々の物品を支持させるのに使用する垂直ボルト係着用支持具に関する。
【０００２】
【従来技術とその課題】
ビル等の天井は、建物躯体の天井部の要所に、該天井部の構造や材質に応じて溶接、ボルト止め、コンクリート中への埋設、デッキプレートへの係嵌等の種々の手段によって吊元金具を取り付け、これら吊元金具に設けたねじ孔に吊りボルトを螺着し、この吊りボルトによって野縁や野縁受けを介して天井材を吊持する構造が一般的に採用されている。
【０００３】
図１２に、建物躯体の天井部（階上床）の下面がデッキプレートにて構成される場合の天井構造の一例を示す。このデッキプレート３１は、凹陥部３１ａと凸条部３１ｂとが交互に配置した波板状をなし、各凹陥部３１ａの両側面に溝部３２，３２が対向状に設けてある。そして、該凹陥部３１ａに、中央部を高く略へ字状に曲成した金属帯板からなる吊元金具４０が両端を溝部３２，３２に係嵌して取り付けられ、この吊元金具４０の中央部に固設したナット４０ａに、吊りボルト４１が上部を螺挿して垂直状態に保持され、この吊りボルト４１の下部に取り付けた吊りハンガー４２にて野縁受け４３が支持されると共に、該野縁受け４３に嵌装したグリップ４４…を介して野縁４５が吊持され、この野縁４５に天井材４６が取り付けられている。
【０００４】
なお、デッキプレート係嵌用の吊元金具４０は、図では最も単純な形態のものを例示しているが、デッキプレート３１の断面形状や負荷重量に応じて係合方式や形態の異なる極めて多種多様なものが用いられている。また、吊りハンガー４２としても多種のものがある。
【０００５】
ところで、上述のような吊りボルト４１を用いる天井構造において、天井裏の空間を利用して、例えば水道管、排水管、ガス管、空調ダクト、電線管等の各種配管を行ったり、電気配線、電話等のケーブル、これら配線用のチャンネル材等の配設を行う場合、その配設仕様が予め判明している設計通りであれば、これら配管や配線に専用の支持部材を天井材取付け施工前に建物躯体の天井部の要所に適当な手段で独立に取り付けたり、天井材取付け施工途上の前記吊元金具４０に吊りボルト４１を保持させる段階で、この吊りボルト４１の中間部位に前記吊りハンガー４２と同様のものを野縁受け４３の支持用とは別に上記配管や配線用として螺着させておくことができる。
【０００６】
しかしながら、実際には、建築の進行に伴って様々な要因により上記配管や配線の仕様変更を必要とする場合が多々あり、また完工後のビル使用中においても、各種の機器や設備の新設、増設、設置場所の変更等により、新たな配管や配線を行ったり、配設替えを要することが少なくない。ところが、既述の吊りハンガー４２やこれに類するものは、いずれも吊りボルト４１に螺挿もしくは嵌装して取り付ける構造であるから、吊りボルト４１に野縁受け４３や野縁４５を吊持させた以降の段階では、当該吊りボルト４１の両端が塞がっているために装着できず、一旦吊持させていた野縁受け４３や野縁４５を取り外して装着することは膨大な労力と時間の無駄になるので到底不可能である。
【０００７】
一方、両端が塞がった吊りボルト４１に取付け可能な支持具としては、例えば図１３に示すようなものがある。同図（Ａ）の支持具５０は、金属板をコ字枠状に曲成したもので、両側板部５０ｂ，５０ｂに設けた切欠部５１，５１を吊りボルト４１に係嵌し、その内側に通した長尺物品Ｍ（図ではチャンネル材）を、基板部５０ａに螺挿した蝶ねじ５２によって吊りボルト４１に押し付けて固定するようになされている。また同図（Ｂ）の支持具５２は、硬質合成樹脂製であり、Ｕ字状枠部５２ａを吊りボルト４１に圧嵌させ、該Ｕ字状枠部５２ａより側方へ張出する受け板部５２ｂ上に長尺物品Ｍ（図ではパイプ）を載せ、Ｕ字状枠部５２ａと受け板部５２ｂの各長孔５３に通した合成樹脂製の締結バンド５４によって長尺物品Ｍを固定するようになされている。
【０００８】
しかるに、これら支持具５０，５２では、吊りボルト４１に対する係着強度に劣るために支持荷重の上限（安全荷重）が小さく、重量負荷が大きくなるとずれ落ちを生じることから、物品Ｍが軽量である場合にしか使用できないという難点があった。
【０００９】
本発明は、上述の事情に鑑みて、天井材を吊持する吊りボルトを利用して天井裏の空間に各種配管や電気配線を施す場合等、特に既設の垂直ボルトに係着して種々の物品を支持させるのに使用する支持具として、両端が塞がった状態の垂直ボルトの任意位置に極めて簡単に取付けることができ、しかも非常に大きな係着強度が得られ、支持させる物品の重量や種類の制約が少ないものを提供することを目的としている。
【００１０】
【課題を解決するための手段】
上記目的を達成するために、本発明の請求項１に係る垂直ボルト係着用支持具は、実施例の参照符号を付して示すと、物品を支持させる支持金具１Ａ〜１Ｌと、この支持金具を垂直ボルト３の任意位置に固定させる固定金具２Ａ〜２Ｂとからなり、支持金具１Ａ〜１Ｌは、垂直ボルト３に側方から嵌合可能な横断面略Ｕ字形をなす嵌合枠部１１と、嵌合枠部１１の側端部に一体形成され固定金具１Ａ〜１Ｌを係嵌する係嵌溝５を備える係嵌枠部６と、嵌合枠部１１の下部より延設された物品取付部１２とを備えると共に、嵌合枠部１１の内周面に垂直ボルト３の雄ねじ部３ａに噛合し得る雌ねじ部４が刻設され、固定金具２Ａ〜２Ｂは、支持金具１Ａ〜１Ｌの係嵌枠部６にその両縦側端部７ａ，７ｂが係嵌する縦片７と、該縦片７の上端部に略Ｌ字状に一体形成される横片８とから構成され、垂直ボルト３の任意位置で雄ねじ部３ａに雌ねじ部４を噛合して嵌合枠部１１に嵌合させた支持金具の係嵌枠部６に係嵌した固定金具の縦片７が垂直ボルト３に当接することにより、支持金具１Ａ〜１Ｌが垂直ボルト３に離脱及び上下動不能に係着されるように設定されてなる。
【００１１】
上記構成の支持具によれば、支持金具１Ａ〜１Ｌの嵌合枠部１１を垂直ボルト３の任意位置に側方から嵌合できると共に、固定金具２Ａ〜２Ｂも該垂直ボルト３に側方から嵌め込むことができ、垂直ボルトに嵌合している支持金具の係嵌枠部に固定金具を上方から係嵌させることにより、嵌合枠部１１は内周の雌ねじ部４が垂直ボルト３の雄ねじ部３ａに噛合した状態で当該垂直ボルト３から開離不能に押さえ込まれた形になるから、支持金具１Ａ〜１Ｌは垂直ボルト３に離脱及び上下動不能に係着される。この場合、支持金具１Ａ〜１Ｌ及び固定金具２Ａ〜２Ｂは、既述の吊りハンガーのように垂直ボルト３の端部から挿嵌させる必要はないから、該垂直ボルトの両端が塞がっている状態であっても全く支障なく係着できる。しかも、支持金具１Ａ〜１Ｌは雌ねじ部４の全体で垂直ボルト３の雄ねじ部３ａに噛合するから、係着強度が非常に大きく、物品取付部１２に支持させる物品の重量負荷が大きくてもずれ落ちることはない。
【００１２】
請求項２の発明では、上記請求項１の垂直ボルト係着用支持具における固定金具は、その縦片７にその縦方向に隆起する楔止め用突起９を有し、固定金具２Ａ〜２Ｂの縦片７を垂直ボルト３に嵌合した支持金具の係嵌枠部６に係嵌させる際に、前記楔止め用突起９が垂直ボルト３に直接に当接するように設定されてなる。このように固定金具２Ａ〜２Ｂの縦片７に楔止め用突起９を隆起形成されてなるため、支持金具の係嵌枠部６に固定金具の縦片７を係嵌させるに際し、例えば縦片上端部の横片８を適当な打圧具で軽く叩いて強制的に押し下げることにより、楔止め用突起９が垂直ボルト３の雄ねじ部３ａの谷間に噛み込んだ状態で垂直ボルト３に強固に楔止め係着されるから、取付け後の振動等による上方への変位が確実に防止される。
【００１３】
また、上記請求項１又は２の垂直ボルト係着用支持具において、請求項３の発明のように、固定金具２Ａ〜２Ｂが、その縦片上端部の横片８に物品取付用の透孔１３乃至ねじ孔１５を有してなるため、支持金具に加えて固定金具にもその横片を利用して物品を支持させることができる。
【００１４】
一方、上記請求項１〜３のいずれかの垂直ボルト係着用支持具において、請求項４の発明のように、支持金具１Ａ〜１Ｌの物品取付部１２が、物品を載置し得る受け形状を有してなるものとすれば、該物品取付部１２を利用して各種配管のパイプ、チャンネル材、ケーブル等の長尺物品の配設を容易に行える。
【００１５】
また、上記請求項１〜４のいずれかの垂直ボルト係着用支持具において、請求項５の発明のように、支持金具１Ａ〜１Ｌの物品取付部１２に透孔１３及びねじ孔１５の一方又は両方が穿設されてなる構成とすれば、各種配管のパイプ、チャンネル材、ケーブル等の長尺物品を配設する際に、該長尺物品を固定するための種々の補助固定具を上記透孔やねじ孔を利用して取り付けることができる。
【００１６】
更に、上記請求項１〜５のいずれかの垂直ボルト係着用支持具において、請求項６の発明のように、支持金具１Ｈの物品取付部１２に垂直ボルト３に係合する係止片２３が一体形成されてなるものとすれば、当該金具にかかる物品の荷重が偏っても、該係止片２３によって当該金具の傾きが防止される。
【００１７】
更に、上記請求項１〜６のいずれかの垂直ボルト係着用支持具において、請求項７の発明のように、支持金具１Ｌの物品取付部１２が、その嵌合枠部１１に一体形成された正面縦板２４と正面縦板の両側端でＬ字状に一体形成された側面縦板２５と正面縦板の上端部で水平にＬ字状に一体形成された平面横板２６とを有し、これら縦板２４，２５及び横板２６に物品取付用の透孔１３及びねじ孔１５の一方又は両方が穿設されてなる構成からなるため、支持金具１Ｌの嵌合枠部１１が嵌合する垂直ボルト３に対し、正面垂直部、左右側面垂直部及び正面水平部の多くの方向に取付面を有し、それだけ施工現場での物品取付条件に対応することができる。
【００１８】
【発明の実施の形態】
以下、本発明に係る垂直ボルト係着用支持具の実施例について、図面を参照して具体的に説明する。図１及び図２に示す第一実施例の垂直ボルト係着用支持具は、共に一枚の金属板より打ち抜き及び曲げ加工して得られる支持金具１Ａと固定金具２Ａとからなる。
【００１９】
支持金具１Ａは、垂直ボルト３に側方から嵌合可能な横断面略Ｕ字形をなす嵌合枠部１１と、嵌合枠部１１の側端部に一体形成され固定金具１Ａ〜１Ｌを係嵌する係嵌溝５を備える係嵌枠部６と、嵌合枠部１１の下部より延設された上向き開放コ字形の物品取付部１２とを備え、嵌合枠部１１の内周面に垂直ボルト３の雄ねじに噛合し得る雌ねじ部４が刻設され、また嵌合枠部１１の略対向する内面上部に幅方向に長い係止用凸部１２ａ，１２ｂが背面からのプレスによって形成されている。しかして、嵌合枠部１１は、図２（ロ）に示すように、垂直ボルト３に雌ねじ部４が噛合する状態で適嵌すると共に、当該嵌合枠部１１の両側縁を結ぶ線よりも垂直ボルト３が僅かに外側へはみ出るように寸法設定されている。また物品取付部１２は、嵌合枠部１１が垂直ボルト３に嵌合した状態において、図２（イ）に示すように垂直ボルト３から離れた位置で垂下するように設定されている。
【００２０】
一方、固定金具２Ａは、支持金具１Ａの係嵌枠部６にその両縦側端部７ａ，７ｂが係嵌する縦片７と、該縦片７の上端部に略Ｌ字状に一体形成される横片８とから構成され、該縦片７に縦方向に上部側が最も隆起量が多く下部側に向かって隆起量が少なくなる楔止め用の突起９が背面からプレスによって隆起形成される。
【００２１】
上記構成の垂直ボルト係着用支持具は、図２（イ）〜（ハ）に示すように、支持金具１Ａの嵌合枠部１１を垂直ボルト３の任意位置に嵌合して内周の雌ねじ部３を該垂直ボルト３の雄ねじ部３ａに噛合させ、支持金具１Ａの係嵌枠部６の係嵌溝５に固定金具１Ａを上方から係嵌させることにより、嵌合枠部１１は内周の雌ねじ部４が垂直ボルト３の雄ねじ部３ａに噛合した状態で当該垂直ボルト３から開離不能に押さえ込まれた形になるから、支持金具１Ａは垂直ボルト３に離脱及び上下動不能に係着される。この場合、支持金具１Ａ及び固定金具２Ａは、既述の吊りハンガーのように垂直ボルト３の端部から挿嵌させる必要はないから、該垂直ボルトの両端が塞がっている状態であっても全く支障なく係着できる。しかも、支持金具１Ａは雌ねじ部４の全体で垂直ボルト３の雄ねじ部３ａに噛合するから、係着強度が非常に大きく（例えば図１３に示すような支持具に比較して安全荷重として数十倍）、物品取付部１２に支持させる物品による重量負荷が大きい場合でもずれ落ちる懸念はない。そして、この垂直ボルト３に係着された支持金具１Ａの物品取付部１２には、例えば図２（イ）に示すチャンネル材Ｔの如き角形の長尺物品を嵌め込んで支承させることができ、係止用凸部１２ａ，１２ｂが該物品の抜け止めとして機能する。
【００２２】
そして固定金具１Ａの縦片７には、その縦方向に隆起する楔止め用突起９を有し、固定金具２Ａの縦片７を垂直ボルト３に嵌合した支持金具の係嵌枠部６に係嵌させる際に、例えば縦片上端部の横片８を適当な打圧具で軽く叩いて強制的に押し下げることにより、楔止め用突起９が垂直ボルト３の雄ねじ部３ａの谷間に噛み込んだ状態で垂直ボルト３に強固に楔止め係着されるから、取付け後の振動等による上方への変位が確実に防止される。
【００２３】
支持金具１Ａ及び固定金具２Ａは、垂直ボルト３の両端が塞がっている状態であっても全く支障なく係着できるから、例えば既述のビル等の天井材の取付け施工（図１２参照）において、建物躯体の天井部のデッキプレートに取り付けた吊元金具に上端部を螺着した吊りボルト（垂直ボルト）に対し、その下端部に野縁受けや野縁を吊持させた後の段階でも任意位置に係着でき、この係着した支持金具１Ａの物品取付部１２を利用して天井裏の空間に、例えば水道管、排水管、ガス管、空調ダクト、電線管等の各種配管を行ったり、電気配線、電話等のケーブル、これら配線用のチャンネル材等の配設を行うことができる。従って、既に前記野縁受けや野縁、更には天井材の取付けが終わった段階で上記配管や配線の仕様変更を必要としたり、また完工後のビル使用中における各種の機器や設備の新設、増設、設置場所の変更等により天井裏に新たな配管や配線等の施工や配設替えを要する場合に、既設の吊りボルトに支持金具１Ａ及び固定金具２Ａを係着して、これら配管や配線等の支承部を形成できる。無論、既に天井材を取付けている場合は、その一部を外して所要の配管や配線の施工を行える。
【００２４】
本発明の垂直ボルト係着用支持具における支持金具としては、前記第一実施例で用いた支持金具１Ａに限らず、図３〜図１０に例示するように、物品取付部１２の形状が種々異なるものを包含する。例えば、図３に示す第二実施例の支持金具１Ｂの物品取付部１２は長尺物品がパイプＰ等の円筒状である場合に対応したＵ字形をなし、図４に示す第三実施例の支持金具１Ｃの物品取付部１２は長尺物品が角筒Ｓやチャンネル材のような角形である場合の支承に適するＬ字形をなし、共に該物品取付部１２の基部側と先端側に設けた透孔１３，１３を利用して、針金１０や合成樹脂製の締結バンド１１の如き補助固定具にて長尺物品を締着固定できるようになっている。また、図５に示す第四実施例の支持金具１Ｄでは、物品取付部１２が上向き開放コ字形をなし、その上に水平配設する角形や円筒状の長尺物品を支承させて基部側と先端側の透孔１３ａ，１３ｂを利用して前記同様の補助固定具にて締着固定できると共に、先端側の透孔１３ｂを利用して、例えば図の仮想線で示す電線管ＥＰのような垂直方向に配設される２本の細径の管体やケーブル等を、Ｗ形の押さえ金具１４ａとボルト１４ｂ及び蝶ナット１４ｃを介して外側で固定することも可能である。
【００２５】
図６に示す第五実施例の支持金具１Ｅでは、平板状の物品取付部１２に径大の透孔１３と径小のねじ孔１４が穿設されており、例えば、透孔１３に金属帯板からなる一対の半円形クリップバンド１６，１６の鍔付き先端部１６ａ，１６ａを嵌め込み、両クリップバンド１６，１６間にパイプ等の円筒形の長尺物品を挟んだ状態で孔付き尾端部１６ｂ，１６ｂをビス１７とナット１８にて締め付けて固定したり、金属帯板からなる開環状のクリップバンド１９に円筒形の長尺物品を通し、このクリップバンド１９の孔付き両端部１９ａ，１９ｂに通したビス１７をねじ孔１５に螺挿して取り付けたり、更にはねじ孔１５を利用して図５に示すようなＷ形の押さえ金具１４ａとボルト１４ｂとで垂直方向に配設される２本の細径の管体やケーブル等を固定することもできる。
【００２６】
図７に示す第六実施例の支持金具１Ｆでは、平板状の物品取付部１２に、径の異なるねじ孔１５ａ〜１５ｃと、径大の透孔１３、長孔２０を設けており、ねじ孔１５ａ〜１５ｃを利用して前記図６に示すクリップバンド１９を始めとする種々のねじ止め式補助固定具を支持荷重に応じてねじ径を選択して取付け、また透孔１３を利用して前記図６に示す半円形クリップバンド１６，１６を始めとする種々の嵌め込み式補助固定具を取付け、更に長孔２０を利用してねじ止め式や嵌め込み式の補助固定具を位置調整可能に取付ける等、多様な物品取付け形態が可能になるように設定されている。
【００２７】
図８に示す第七実施例の支持金具１Ｇでは、物品取付部１２に、全体のＬ字形折曲による下段受け部２１と、その垂直部の切り起こしによる上段受け部２２との２段に形成され、基部と両受け部２１，２２の立ち上げ先端部に各々透孔１３が設けてあり、両受け部２１，２２の一方又は両方で水平配設する長尺物品を支承し、それぞれ透孔１３を利用して既述の針金や締結バンドにて締着固定できるようになっている。
【００２８】
図９に示す第八実施例の支持金具１Ｈでは、Ｌ字形をなす物品取付部１２の垂直部に、半円弧状切欠部２３ａを有する係止片２３が背面側へ切り起こし形成されると共に、同水平部に各々径の異なる複数個の透孔１３やねじ孔１５が設けてある。この場合、透孔１３やねじ孔１５を利用して前記同様の種々の補助固定具を介して各種物品を支持できるが、その支持位置によって当該支持金具１Ｈにかかる荷重が偏っても、垂直ボルト３に嵌合枠部１１を嵌合させる際、図示のように係止片２３の切欠部２３ａを当該垂直ボルト３に係嵌させることにより、荷重の偏りによる当該支持金具１Ｈの傾きを確実に防止できる。
【００２９】
図１０に示す第九実施例の支持金具１Ｌの物品取付部１２は、その嵌合枠部１１に一体形成された正面縦板２４と正面縦板２４の両側端でＬ字状に一体形成された平面横板２６とを有し、これら縦板２４，２５及び横板２６に物品取付用の透孔１３やねじ孔１５を穿設してなるものである。この実施例によれば、支持金具１Ｌの嵌合枠部１１が嵌合する垂直ボルト３に対し、正面垂直部、左右側面垂直部及び正面水平部の多くの方向に取付面を有してなるため、それだけ施工現場における物品取付条件に対応することができる。
【００３０】
なお、本発明においては、支持金具１の物品取付部１２について、上記の例示以外の様々な形態とすることができ、受け部形状とする場合でも例えば垂直部の面方向に沿う両側にＬ字形等の受け部を形成し、垂直ボルト３の両側を通って水平配設する二本の長尺物品を支承させることも可能であり、また透孔１３やねじ孔１５の形成位置や個数も種々設定できる。更に、支持対象とする物品は、長尺のものに限らず、例えば電気配線の中継・分岐部とするアウトレットボックス等、配線や配管の途上に介在させる各種部材や機器を支持金具の物品取付部１２で固定するようにしてもよい。
【００３１】
【発明の効果】
請求項１の発明によれば、ビル等の天井材を吊持する吊りボルトを利用して天井裏の空間に各種配管や電気配線を施す場合等、特に既設の垂直ボルトに係着して種々の物品を支持させるのに使用する垂直ボルト係着用支持具として、物品取付部を有する支持金具と、この支持金具を垂直ボルトの任意位置に固定させる固定金具とからなり、両金具を共に垂直ボルトに対して側方からの嵌合によって任意位置に極めて簡単に取付けることができ、しかも支持金具の雌ねじ部が垂直ボルトの雄ねじに噛合するために非常に大きな係着強度が得られ、支持させる物品の重量や種類の制約が少ないものが提供される。しかして、この支持具を用いれば、例えば上記の天井材の取付け施工において、建物躯体の天井部のデッキプレートに取り付けた吊元金具に上端部を螺着した吊りボルトに対し、その下端部に野縁受けや野縁を吊持させた後でも任意位置に係着できるから、これら吊持後の段階や天井材の取付けが終わった段階で上記配管や配線の仕様変更を必要としたり、また完工後のビル使用中における各種の機器や設備の新設、増設、設置場所の変更等により天井裏に新たな配管や配線等の施工や配設替えを要する場合でも、前記吊りボルトを支承部として利用することが可能となる。

【００３６】
請求項６の発明によれば、上記の垂直ボルト係着用支持具において、支持金具の物品取付部に垂直ボルトに係合する係止片を有するから、当該金具にかかる物品の荷重が偏っても、当該金具の傾きが防止される。

By the way, in the ceiling structure using the suspension bolt 41 as described above, for example, various pipes such as water pipes, drain pipes, gas pipes, air conditioning ducts, electric pipes, etc. When installing cables such as telephones and channel materials for wiring, etc., if the installation specifications are as previously known, support members dedicated to these pipes and wiring should be installed before installing the ceiling material. At the stage where the suspension bolts 41 are held on the ceiling of the building frame by appropriate means, or when the suspension bolts 41 are held by the suspension bracket 40 in the process of installing the ceiling material, the suspension bolts 41 are suspended at the intermediate portions. A thing similar to the hanger 42 can be screwed for the piping and wiring separately from the support for the field receiver 43.
[0006]
However, in practice, there are many cases where it is necessary to change the specifications of the piping and wiring due to various factors as the building progresses, and new equipment and facilities are newly installed, even during use of the building after completion. It is often the case that new piping or wiring is required or relocation is required due to expansion, change of installation location, or the like. However, the above-described suspension hanger 42 and the like are all structured to be screwed or fitted to the suspension bolt 41, so that the suspension receiver 41 and the field edge 45 are suspended by the suspension bolt 41. In the subsequent stages, both ends of the suspension bolt 41 cannot be installed because they are closed, and it is a waste of labor and time to remove and install the field edge receiver 43 and the field edge 45 once suspended. It is impossible at all.
[0007]
On the other hand, as a support that can be attached to the suspension bolt 41 whose both ends are closed, for example, there is a support as shown in FIG. The support tool 50 in FIG. 2A is a metal plate bent into a U-shaped frame shape, and the notch portions 51 and 51 provided on both side plate portions 50b and 50b are engaged with the suspension bolt 41, and the inner side thereof. A long article M (a channel material in the figure) passed through is pressed and fixed to the suspension bolt 41 by a thumbscrew 52 screwed into the substrate portion 50a. Further, the support tool 52 in FIG. 5B is made of a hard synthetic resin, and a U-shaped frame portion 52a is press-fitted to the suspension bolt 41, and a receiving plate that protrudes laterally from the U-shaped frame portion 52a. A long article M (pipe in the figure) is placed on the part 52b, and the long article M is fixed by a synthetic resin fastening band 54 that passes through the long holes 53 of the U-shaped frame part 52a and the receiving plate part 52b. It is made like that.
[0008]
However, in these support tools 50 and 52, since the engagement strength with respect to the suspension bolt 41 is inferior, the upper limit (safety load) of the support load is small, and when the weight load increases, the article M is light. There was a difficulty that it could only be used in some cases.
[0009]
In view of the above-mentioned circumstances, the present invention uses various types of pipes and electrical wiring in the space behind the ceiling using a suspension bolt that suspends the ceiling material. As a support tool used to support an article, it can be attached very easily to an arbitrary position of a vertical bolt with both ends closed, and a very large fastening strength can be obtained, and the weight and type of the article to be supported. It aims to provide something with less restrictions.
