【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１４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１５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、物品を支持させる支持金具と、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、支持金具は、垂直ボルトに側方から嵌合可能な横断面略Ｕ字形をなす嵌合枠部と、この嵌合枠部の下部より延設された物品取付部とを備えると共に、嵌合枠部の内周面に垂直ボルトの雄ねじに噛合し得る雌ねじ部が刻設され、固定金具は、縦壁部とその左右両側から当該縦壁部の一面側へ延設された一対の抱持片とで、支持金具の嵌合枠部に上方から外嵌し得る抱持枠を形成すると共に、両抱持片の間で垂直ボルトが側方から出入可能で且つ支持金具の嵌合枠部が側方から出入不能な間隔のボルト出入部が構成され、垂直ボルトの任意位置に雌ねじ部を噛合して嵌合させた支持金具の嵌合枠部に、それよりも上位で該垂直ボルトに嵌め込んだ固定金具を縦壁部が垂直ボルトに当接した形で上方から外嵌させることにより、支持金具が垂直ボルト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、支持金具の嵌合枠部を垂直ボルトの任意位置に側方から嵌合できると共に、固定金具も該垂直ボルトに側方から嵌め込むことができ、この固定金具の嵌合位置を上位として、下位に嵌合している支持金具の嵌合枠部に固定金具を上方から外嵌させることにより、該嵌合枠部は内周の雌ねじ部が垂直ボルトの雄ねじに噛合した状態で当該垂直ボルトから開離不能に押さえ込まれた形になるから、支持金具は垂直ボルトに離脱及び上下動不能に係着される。この場合、支持金具及び固定金具は、既述の吊りハンガーのように垂直ボルト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、支持金具は雌ねじ部の全体で垂直ボルトの雄ねじに噛合するから、係着強度が非常に大きく、物品取付部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、縦壁部の内面上部に小凸部を有し、垂直ボルトに嵌合した支持金具の嵌合枠部に外嵌した際に、該小凸部と縦壁部の下縁とが垂直ボルトに直接に当接するように設定されてなるものとしている。この場合、固定金具は、抱持枠の内側上部が小凸部の突出分だけ内側下部よりも狭くなっているから、支持金具の嵌合枠部に対する外嵌位置が下がるほど当該嵌合枠部を強く締め付ける形になり、この嵌合枠部への外嵌に際して例えば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、小凸部が垂直ボルトの雄ねじの谷間に噛み込んだ状態で垂直ボルトに強固に係着するから、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】
しかして、上記請求項１又は２の垂直ボルト係着用支持具における固定金具は、請求項３の発明のように、平板状の縦壁部と両抱持片とで平面視略ワ字形又は略コ字形の抱持枠を形成したものや、請求項４の発明のように、平板状の縦壁部の上部より弧状に延出する一方の抱持片と、該縦壁部の下部より弧状に延出する他方の抱持片とを有すると共に、両抱持片の上下間にボルト出入部が構成されたものとすれば、金属板材の曲成によって容易に製作可能である。しかして、請求項４の固定金具は、横向き状態で該ボルト出入部に垂直ボルトを嵌入させた上で、縦向き状態に変えて該垂直ボルトに嵌装させる。
【００１４】
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、固定金具が、縦壁部の上下縁の一方から外向きに張出した支持片を有してなる構成とすれば、支持金具に加えて固定金具にも支持片を利用して物品を支持させることができる。
【００１５】
一方、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、支持金具の物品取付部が、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。
【００１６】
また、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、支持金具の物品取付部に透孔及びねじ孔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。
【００１７】
更に、上記請求項１〜７のいずれかの垂直ボルト係着用支持具において、請求項８の発明のように、支持金具の物品取付部に垂直ボルトに係合する係止片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、該係止片によって当該金具の傾きが防止される。
【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、この嵌合枠部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、平板状の縦壁部２１と、その左右の一側から当該縦壁部２１の一面側へ延設された短い円弧状の抱持片２２と、同他側から同様に延設された長い円弧状の抱持片２３とで、支持金具１Ａの嵌合枠部１１に外嵌し得る大きさの平面視略ワ字形の抱持枠を構成すると共に、両抱持片２２，２３の端縁間によって垂直ボルト３が出入可能で且つ支持金具１Ａの嵌合枠部１１が出入不能な間隔のボルト出入部５を形成しており、縦壁部２１の内面上部に小凸部２１ａが背面からのプレスによって形成されている。
【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の雄ねじに噛合させると共に、この嵌合位置よりも上位に、固定金具２Ａを該垂直ボルト３にボルト出入部５より内側へ嵌め込み、この固定金具２Ａを下降させて支持金具１Ａの嵌合枠部１１に外嵌させることにより、該固定金具２Ａの縦壁部２１がその内面上部の小凸部２１ａと下縁２１ｂとで垂直ボルト３に当接した形で、嵌合枠部１１を当該垂直ボルト３から開離不能に押さえ込み、もって支持金具１Ａが垂直ボルト３に離脱及び上下動不能に係着される。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】
この場合、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１４参照）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。
【００２３】
しかして、固定金具２Ａは、抱持枠の内側上部が小凸部６の突出分だけ内側下部よりも狭くなっており、支持金具１Ａの嵌合枠部１１に対する外嵌位置が下がるほど当該嵌合枠部を強く締め付ける形になるから、該嵌合枠部１１に外嵌させる際、例えば適当な打圧具で軽く叩くようにして強制的に押し下げることにより、小凸部２１ａが垂直ボルト３の雄ねじの谷間に噛み込んだ状態で垂直ボルト３に強固に係着し、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。また、支持金具１Ａは雌ねじ部４の全体で垂直ボルト３の雄ねじに噛合するから、係着強度が非常に大きく（例えば図１５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。
【００２４】
図３は本発明に係る垂直ボルト係着用支持具の他の実施例における固定金具を示す。同図（イ）の第二実施例の固定金具２Ｂは、平板状の縦壁部２１と、その左右両側から当該縦壁部２１の一面側へ延設された一対の平板状の抱持片２２，２３とで、平面視略コ字形の抱持枠を構成すると共に、両抱持片２２，２３の内側に折り返し状に曲成された端縁部２２ａ，２３ａ間でボルト出入部５を形成している。同図（ロ）の第三実施例の固定金具２Ｃは、平板状の縦壁部２１の上部より円弧状に延出する一方の抱持片２２と、該縦壁部２１の下部より円弧状に延出する他方の抱持片２３とを有すると共に、両抱持片２２，２３の上下間にボルト出入部５が構成されている。同図（ハ）の第四実施例の固定金具２Ｄは前記第一実施例における固定金具２Ａの縦壁部２１の下縁に、また同図（ニ）の第五実施例の固定金具２Ｅは前記第一実施例における固定金具２Ａの縦壁部２１の下縁に、それぞれ係止孔２４ａを有する支持片２４が外向きに張出するように一体形成されたものである。
【００２５】
しかして、これら固定金具２Ｂ〜２Ｅにおいても、第一実施例の固定金具２Ａと同様に、抱持枠として支持金具１（前記１Ａと後述の他の実施例の支持金具１Ｂ〜１Ｈ等を含む総称としての符号）の嵌合枠部１１に外嵌し得る大きさを備えると共に、ボルト出入部５は垂直ボルト３が出入り可能で前記嵌合枠部１１を出入り不能とする間隔に設定され、且つ縦壁部２１の内面上部に小凸部２１ａを設けてある。従って、これら固定金具２Ｂ〜２Ｅは、前記第一実施例の固定金具２Ａと同様に、垂直ボルト３にボルト出入部５より嵌装し、当該垂直ボルト３に嵌合している支持金具１の嵌合枠部１１に外嵌させることにより、該支持金具を垂直ボルト３に離脱及び上下動不能に係着固定できる。図４は、第二実施例の固定金具２Ｂにより、前記第一実施例で用いた支持金具１Ａを垂直ボルト３に係着固定した状態を示す。
【００２６】
ただし、第三実施例の固定金具２Ｃは、これを垂直ボルト３に嵌装する際、図５の仮想線で示すように横向き状態でボルト出入部５に該垂直ボルト３を嵌入させた上で、同図実線で示すように縦向き状態に変えることにより、該垂直ボルト３に嵌装させる。この嵌装後に支持金具１の嵌合枠部１１に外嵌させる操作は前記第一実施例と同じである。なお、第四及び第五実施例の固定金具２Ｄ，２Ｅでは、例えば図１３に示すように、支持片２４の係止孔２４ａに係止したフックＦや他の種々の吊り具を介し、電線Ｌ等の比較的軽量の物品を支承して配設するのに利用できる。
【００２７】
一方、本発明の垂直ボルト係着用支持具における支持金具１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６〜図１２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６に示す第六実施例の支持金具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７に示す第七実施例の支持金具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６や合成樹脂製の締結バンド７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８に示す第八実施例の支持金具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８ａとボルト８ｂ及び蝶ナット８ｃを介して外側で固定することも可能である。
【００２８】
図９に示す第九実施例の支持金具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９，９の鍔付き先端部９ａ，９ａを嵌め込み、両クリップバンド９，９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９ｂ，９ｂをビス２５とナット２６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２７に円筒形の長尺物品を通し、このクリップバンド２７の孔付き両端部２７ａ，２７ｂに通したビス２５をねじ孔１４に螺挿して取り付けたり、更にはねじ孔１４を利用して図８に示すようなＷ形の押さえ金具８ａとボルト８ｂ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。
【００２９】
図１０に示す第十実施例の支持金具１Ｆでは、平板状の物品取付部１２に、径の異なるねじ孔１４ａ〜１４ｃと、径大の透孔１３、長孔１４を設けており、ねじ孔１４ａ〜１４ｃを利用して前記図９に示すクリップバンド２７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９に示す半円形クリップバンド９，９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１４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。
【００３０】
図１１に示す第十一実施例の支持金具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１６と、その垂直部の切り起こしによる上段受け部１７との２段に形成され、基部と両受け部１６，１７の立ち上げ先端部に各々透孔１３が設けてあり、両受け部１６，１７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。
【００３１】
図１２に示す第十二実施例の支持金具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１８ａを有する係止片１８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１４が設けてある。この場合、透孔１３やねじ孔１４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１８の切欠部１８ａ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。
【００３２】
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１４の形成位置や個数も種々設定できる。一方、固定金具２についても、例えばボルト出入部５を斜めに設定したり、第四及び第五実施例の固定金具２Ｄ，２Ｅにおける支持片２４を縦壁部２１の上縁側に延設したり、該支持片２４をＬ字形やＵ字形とする等、例示した以外の種々の形態が可能である。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１の物品取付部１２で固定するようにしてもよい。
【００３３】
【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。

BACKGROUND OF THE INVENTION
The present invention relates to various articles particularly engaged with existing vertical bolts, such as when various pipes and electrical wiring are applied to the space behind the ceiling using suspension bolts that suspend ceiling materials of buildings such as buildings. The present invention relates to a vertical bolt engaging support used for supporting a skirt.
[0002]
[Prior art and its problems]
The ceiling of a building or the like is suspended at various points of the ceiling of the building frame by various means such as welding, bolting, embedding in concrete, or engaging with a deck plate according to the structure and material of the ceiling. A structure is generally adopted in which a main bracket is attached, a suspension bolt is screwed into a screw hole provided in the suspension bracket, and a ceiling material is suspended by the suspension bolt via a field edge or a field edge receiver. .
[0003]
FIG. 14 shows an example of the ceiling structure in the case where the lower surface of the ceiling (floor floor) of the building frame is constituted by a deck plate. The deck plate 31 has a corrugated shape in which concave portions 31a and ridges 31b are alternately arranged, and groove portions 32 and 32 are provided in opposite sides on both side surfaces of the concave portions 31a. A hanging metal fitting 40 made of a metal band plate having a central portion bent in a substantially U-shape is attached to the recessed portion 31a with both ends engaged with the groove portions 32, 32. A suspension bolt 41 is screwed into an upper portion of the nut 40a fixed at the center and is held in a vertical state, and a field hanger 43 is supported by a suspension hanger 42 attached to the bottom of the suspension bolt 41. A field edge 45 is suspended through grips 44 fitted to the field edge receiver 43, and a ceiling material 46 is attached to the field edge 45.
[0004]
The hanging bracket 40 for engaging with the deck plate is illustrated in the simplest form in the drawing, but there are a great variety of engagement methods and forms depending on the cross-sectional shape and load weight of the deck plate 31. Various things are used. There are various types of hanging hangers 42.
[0005]
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.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a vertical bolt engaging support device according to claim 1 of the present invention comprises a support fitting for supporting an article and a fixing fitting for fixing the support fitting to an arbitrary position of the vertical bolt, The support bracket includes a fitting frame portion having a substantially U-shaped cross section that can be fitted to a vertical bolt from the side, and an article mounting portion extending from a lower portion of the fitting frame portion, and a fitting frame. A female threaded portion that can mesh with a male screw of a vertical bolt is formed on the inner peripheral surface of the vertical portion, and the fixing bracket is a pair of holding pieces that extend from the left and right sides of the vertical wall portion to one surface side of the vertical wall portion. and in, to form a holding frame which can fitted from above to the fitting frame portion of the support bracket, the vertical bolt between the two retaining pieces fitting frame portion and the support bracket can and out from the side bolt and out of and out non intervals from the side is formed, engage the female thread portion in an arbitrary position of the vertical bolt By fitting the fixing bracket fitted to the vertical bolt at a higher position to the fitting frame portion of the support fitting fitted in this manner, the vertical wall portion is externally fitted from the top in contact with the vertical bolt, The support metal fitting is set to be engaged with the vertical bolt so as not to be detached and vertically movable.
[0011]
According to the support having the above-described configuration, the fitting frame portion of the support fitting can be fitted to an arbitrary position of the vertical bolt from the side, and the fixing fitting can be fitted to the vertical bolt from the side. The fitting position of the fixing bracket is externally fitted to the fitting frame portion of the support fitting that is fitted in the lower position, so that the internal thread portion of the fitting frame portion is the male screw of the vertical bolt. In this state, the support metal fitting is engaged with the vertical bolt so that it cannot be separated and cannot be moved up and down. In this case, it is not necessary to insert the support bracket and the fixing bracket from the end of the vertical bolt as in the case of the hanging hanger described above, so even if both ends of the vertical bolt are closed, there is no problem. I can wear it. In addition, since the support fitting meshes with the male screw of the vertical bolt throughout the female screw portion, the engagement strength is very high, and even if the weight load of the article supported by the article mounting portion is large, it does not fall off.
[0012]
According to a second aspect of the present invention, the fixing bracket in the vertical bolt engaging support device according to the first aspect has a small convex portion on the inner surface of the vertical wall portion, and a fitting frame portion of the supporting bracket fitted to the vertical bolt. When it is externally fitted, the small convex portion and the lower edge of the vertical wall portion are set so as to come into direct contact with the vertical bolt. In this case, since the inner upper part of the holding frame is narrower than the inner lower part by the protrusion of the small convex part, the fitting frame part is lowered as the fitting position of the support metal part with respect to the fitting frame part is lowered. In the state where the small convex part is bitten in the valley of the male thread of the vertical bolt, for example, by lightly striking it with an appropriate striking tool and forcibly pushing it down when fitting to the fitting frame part Since it is firmly engaged with the vertical bolt, upward displacement due to vibration after mounting is reliably prevented.
[0013]
Thus, the fixing bracket in the vertical bolt engaging support device according to claim 1 or 2 is substantially in the shape of a substantially square character in plan view or substantially in a flat vertical wall portion and both holding pieces as in the invention of claim 3. A U-shaped holding frame, or one holding piece extending in an arc shape from the upper part of the flat vertical wall part and an arc shape from the lower part of the vertical wall part as in the invention of claim 4 If it has the other holding piece extended in this and the bolt insertion part was comprised between the upper and lower sides of both holding pieces, it can manufacture easily by the bending of a metal plate material. Thus, the fixing metal fitting of claim 4 is inserted into the vertical bolt in the vertical direction after the vertical bolt is inserted into the bolt in / out portion in the horizontal state.
[0014]
Further, in the vertical bolt engaging support device according to any one of claims 1 to 4, as in the invention of claim 5, the fixing bracket has a support piece projecting outward from one of the upper and lower edges of the vertical wall portion. If it has the structure which has, it can support an article | item using a support piece also in a fixing metal fitting in addition to a support metal fitting.
[0015]
On the other hand, in the vertical bolt engaging support device according to any one of the first to fifth aspects, the article mounting portion of the support fitting has a receiving shape on which the article can be placed as in the invention of the sixth aspect. If so, it is possible to easily arrange long articles such as pipes, channel materials, and cables of various pipes by using the article attachment portion.
[0016]
Further, in the vertical bolt engaging support device according to any one of claims 1 to 6, as in the invention of claim 7, one or both of a through hole and a screw hole are formed in the article mounting portion of the support fitting. With this configuration, when arranging long articles such as pipes, channel materials, cables, etc. of various pipes, various auxiliary fixtures for fixing the long articles are used through the above through holes and screw holes. Can be attached.
[0017]
Furthermore, in the vertical bolt engaging support device according to any one of claims 1 to 7, as in the invention of claim 8, a locking piece that engages with the vertical bolt is integrally formed on the article mounting portion of the support fitting. If it becomes, even if the load of the article concerning the metal fitting is biased, the locking piece prevents the metal fitting from being inclined.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the vertical bolt engaging support according to the present invention will be specifically described below with reference to the drawings. The vertical bolt engaging support of the first embodiment shown in FIGS. 1 and 2 is composed of a support fitting 1A and a fixing fitting 2A both obtained by punching and bending from a single metal plate.
[0019]
The support metal fitting 1A has a fitting frame portion 11 having a substantially U-shaped cross section that can be fitted to the vertical bolt 3 from the side, and an upward open U-shaped article attachment extending from the lower portion of the fitting frame portion 11. And a female screw part 4 that can be engaged with the male screw of the vertical bolt 3 is formed on the inner peripheral surface of the fitting frame part 11, and the fitting frame part 11 is long in the width direction on the upper part of the inner surface substantially facing the fitting frame part 11. The locking convex portions 12a and 12b are formed by pressing from the back side. As shown in FIG. 2 (b), the fitting frame portion 11 fits properly in a state in which the female screw portion 4 is engaged with the vertical bolt 3, and from the line connecting both side edges of the fitting frame portion 11. The vertical bolt 3 is dimensioned so that it slightly protrudes outward. In addition, the article mounting portion 12 is set to hang down at a position away from the vertical bolt 3 as shown in FIG. 2A in a state where the fitting frame portion 11 is fitted to the vertical bolt 3.
[0020]
On the other hand, the fixing bracket 2A has a flat plate-like vertical wall portion 21, a short arc-shaped holding piece 22 extended from one side of the left and right sides to the one surface side of the vertical wall portion 21, and the same from the other side. A long arc-shaped holding piece 23 extending in the shape of the holding frame 1A constitutes a holding frame having a generally U-shaped holding frame having a size capable of being externally fitted to the fitting frame portion 11 of the support fitting 1A. Between the end edges of the pieces 22 and 23, a vertical bolt 3 can be inserted and removed, and the fitting frame portion 11 of the support metal fitting 1 </ b> A is formed with a bolt insertion / exit portion 5 at an interval where it cannot enter / exit. Small convex portions 21a are formed by pressing from the back.
[0021]
As shown in FIGS. 2 (A) to 2 (C), the vertical bolt engaging support device having the above-described configuration is configured such that the fitting frame portion 11 of the support fitting 1A is fitted to an arbitrary position of the vertical bolt 3 and the inner peripheral female screw. The portion 3 is engaged with the male screw of the vertical bolt 3, and the fixing bracket 2A is fitted into the vertical bolt 3 inward from the bolt insertion / removal portion 5 above the fitting position, and the fixing bracket 2A is lowered and supported. By fitting outside the fitting frame portion 11 of the metal fitting 1A, the vertical wall portion 21 of the fixing metal fitting 2A is fitted to the vertical bolt 3 at the small convex portion 21a and the lower edge 21b at the upper part of the inner surface. The frame portion 11 is pressed from the vertical bolt 3 so as not to be separated, and the support fitting 1A is engaged with the vertical bolt 3 so as not to be detached and vertically movable. And, in the article mounting portion 12 of the support fitting 1A attached to the vertical bolt 3, for example, a rectangular long article such as the channel material T shown in FIG. 2 (a) can be fitted and supported. The locking projections 12a and 12b function as a stopper for the article.
[0022]
In this case, since the support metal 1A and the fixing metal 2A can be engaged without any trouble even when both ends of the vertical bolt 3 are closed, for example, installation work for a ceiling material such as a building described above (see FIG. 14). ), The suspension bolt (vertical bolt) with the upper end screwed to the suspension bracket attached to the deck plate on the ceiling of the building frame is suspended at the lower end with a field edge receiver and field edge. At any stage, it can be attached to any position, and various pipes such as water pipes, drain pipes, gas pipes, air conditioning ducts, electric pipes, etc., can be installed in the space behind the ceiling using the article mounting part 12 of the attached support bracket 1A. Or wiring for electrical wiring, telephone cables, etc., channel materials for these wirings, and the like. Therefore, it is necessary to change the specifications of the piping and wiring at the stage where the installation of the field ledge and the field edge, and also the ceiling material has been completed, and new installation of various equipment and facilities during use of the building after completion, When construction or relocation of new piping or wiring is required on the back of the ceiling due to expansion, change of installation location, etc., the supporting bracket 1A and the fixing bracket 2A are attached to the existing hanging bolt, and these piping and wiring are connected. Etc. can be formed. Of course, if you have already installed the ceiling material, you can remove the part and install the required piping and wiring.
[0023]
Thus, in the fixing bracket 2A, the inner upper portion of the holding frame is narrower than the inner lower portion by the amount of the protrusion of the small convex portion 6, and the fitting is reduced as the outer fitting position of the supporting bracket 1A with respect to the fitting frame portion 11 is lowered. Since the fitting frame portion is strongly tightened, when the outer fitting portion 11 is externally fitted to the fitting frame portion 11, the small convex portion 21a is forced down by, for example, lightly striking with an appropriate striking tool, so that the small convex portion 21a becomes the vertical bolt 3. In this state, the vertical bolt 3 is firmly engaged with the male screw valley, and the upward displacement due to vibration after mounting is reliably prevented. Further, since the support fitting 1A meshes with the male screw of the vertical bolt 3 as a whole in the female screw portion 4, the engagement strength is very large (for example, several tens of times as a safety load compared to the support shown in FIG. 15). Even if the weight load by the article supported by the article mounting portion 12 is large, there is no fear of slipping off.
