Description

【０００１】
【発明の属する技術分野】
本発明は、建築物の壁面、天井面等に沿って配設されるパイプを抱持支承するパイプ支持バンドの仮止め具に関し、詳しくは、パイプを抱持する２つ割バンド本体の一対の取付片部で足部材を挟み込み、ボルト、ナットで両者を固着するパイプ支持バンドの仮止め具に関する。
【０００２】
【従来の技術】
特許文献１は、本出願人が先に提案したパイプ支持バンド用仮止め具の一例を示すものである。この従来技術によれば、マンション等の高層建築物の壁面などに沿って、縦樋等のパイプを配設するに際し、基部が互いにヒンジ結合された２つ割りのバンド本体をパイプの周体に抱持させ、各バンド本体の先端に形成された取付片部を、壁面などに取付けられた足部材を挟み込むように重合させ、且つ後記する仮止め具を添装して、これらを一体的にボルト・ナットで締結することにより壁面などへの配設がなされる。
【０００３】
上記仮止め具は板金材等からなり、一方の取付片部の片面に添装される取付ベースと、その上下端部から垂直に延設された互いに並行な上下一対の片部とより構成される。この片部には一方の取付片部及び他方の取付片部にそれぞれ係止する２種の係止爪を備え、また、取付ベースには取付片部に開設されたボルト用貫通孔に対応する位置に、開口径がボルト軸部の山径よりやや小さく且つ遠心方向の切込み部を備えたボルト挿通孔が設けられている。
【０００４】
このような仮止め具を用いて、上記バンド本体によりパイプを建屋の壁面等に配設する場合、予め、取付ベース側の上記係止爪を一方の取付片部に係止させて取付ベースをこの取付片部の片面に添装させ、ボルトを取付ベースに形成された上記ボルト挿通孔に圧入させると共に取付片部に開設された貫通孔に貫挿させておく。次いで、壁面などに取付けられた上記足部材の貫通孔（長孔）に上記ボルトを挿通させ、パイプの周体に２つ割りバンド本体を抱持させる。そして、他方の取付片部を、上記もう一方の係止爪に係止させつつ、この取付片部に開設された貫通孔に上記ボルトを貫挿させ、該ボルトにナットを螺合させて上記締結固着がなされる。
【０００５】
上記のような仮止め具を用いたパイプの配設作業においては、取付ベースに形成されたボルト挿通孔の開口径がボルト軸部の山径より小さくされているから、このボルト挿通孔及び上記貫通孔にボルトを貫挿させた状態では、その抜けが防止され、作業中ボルトから手を離しても、ボルトが抜け出して落下するような懸念がない。また、片部に形成された２種の係止爪により、足部材を挟みこんだ状態で両バンド本体の取付片部が重合状態に維持されるから、ナットの締付前においてバンド本体から手を離してもバンド本体が外れることがない。従って、作業者は両手がフリーとなり、パイプを抱持しながらのボルト・ナットの締付作業を効率よく行うことができる。特に、マンション等の高層建築物の危険な高所作業を伴う建築現場においては、このような作業性の良さは安全性の点でも極めて高く評価されている。

【発明が解決しようとする課題】
上記のようなパイプ支持バンドの仮止め具は、パイプ配設作業の作業効率を飛躍的に向上させ、また作業の安全性の面でも高く評価されているが、次のような問題点も指摘されるようになった。
【０００８】
即ち、仮止め具の係止爪を、パイプ支持バンドの取付片部に導入して仮止めする際に、係止爪が取付片部の上下端などに当たってしまい、係止爪を取付片部にひっかけることがたびたび起こっており、こうなると、作業性の悪化が懸念され、特に、高層建築物の危険な高所作業を伴う建築現場において、安全性の点でも懸念される。
【０００９】
本発明は、上記に鑑みなされたものであり、仮止め具の係止爪をパイプ支持バンドの取付片部に導入することが容易にできるパイプ支持バンドの仮止め具を提供するものである。
【００１０】
【課題を解決するための手段】
上記目的を達成するため、請求項１の発明に係るパイプ支持バンドの仮止め具では、パイプを抱持する２つ割バンド本体の一対の取付片部で建屋に固設される足部材を挟み込み、この一対の取付片部及び足部材にはボルトの軸部を挿通する１以上の貫通孔が各々開設され、ボルト及びナットで一対の取付片部を足部材に固着するパイプ支持バンドの仮止め具であって、一方の取付片部の片面に添装される取付ベースと、この取付ベースの添装状態で貫通孔に対応する位置に形成されたボルト係止用空所と、取付ベースの上端及び下端から略垂直方向に延設され、他方の取付片部に係止する係止爪を設けた一対の上片部及び下片部とよりなり、この上片部及び下片部の先側は互いに開くよう折曲された取付片部用ガイド部とされていることを特徴とする。
【００１１】
ここに、ボルト係止用空所の用語は、本発明の仮止め具に対してボルトを装着させるべき部材を総括規定したものであり、種々の実施態様が考えられる。実施形態においては、ボルト係止用孔部で形成したもの、ボルト係止用空所で形成したもの、ボルト挿通孔とボルト係止用長孔部とで形成したものを紹介している。
【００１２】
請求項２の発明に係るパイプ支持バンドの仮止め具では、請求項１において、ボルト係止用空所は、ボルト係止用孔部によって形成されている。
【００１３】
このような構成の仮止め具を用いて建屋の壁面等にパイプの配設を行う場合、前記と略同様に、予め、取付ベースを取付片部の片面に添装させ、ボルトを取付ベースに形成された上記ボルト係止用孔部に挿通させると共に取付片部に開設された貫通孔に貫挿させておく。次いで、壁面に取付けられた上記足部材の貫通孔（長孔）に上記ボルトを挿通させ、パイプの周体に２つ割りバンド本体を抱持させる。そして、他方の取付片部を、上記係止爪に係止させつつ、この取付片部に開設された貫通孔に上記ボルトを貫挿させ、該ボルトにナットを螺合させて各部材の締結固着がなされる。
【００１４】
斯かる配設作業において、仮止め具の係止爪を、パイプ支持バンドの取付片部に導入して仮止めする際には、取付片部の上下端のそれぞれが、取付片部用ガイド部によって誘導されるため、係止爪を取付片部に導入しやすくできる。そのため、作業性がよく作業の合理化が図れ、また、高所作業における安全面にも寄与できる。
【００１５】
請求項３の発明に係るパイプ支持バンドの仮止め具では、請求項１において、ボルト係止用空所は、取付ベースの側辺部より切り欠かれ添装状態で貫通孔に対応する位置にまで延びるボルト係止用切欠部によって形成されている。
【００１６】
このような構成の仮止め具を用いて建屋の壁面等にパイプの配設を行う場合、予め、ボルトの軸部をボルト係止用切欠部の切欠開口部より横移動させて係止させる。この状態で取付ベースを取付片部の片面に添装させると共に、ボルトの軸部を取付片部に開設された貫通孔に貫挿させておく。次いで、壁面に取付けられた上記足部材の貫通孔（長孔）に上記ボルトを挿通させ、パイプの周体に２つ割りバンド本体を抱持させる。そして、他方の取付片部を、上記係止爪に係止させつつ、この取付片部に開設された貫通孔に上記ボルトを貫挿させ、該ボルトにナットを螺合させて各部材の締結固着がなされる。
【００１７】
斯かる配設作業において、ボルト係止用切欠部にボルトを係止させる場合、ボルトの軸部をボルト係止用切欠部の切欠開口部より横移動させて係止させるので、ボルトのねじ山に何等衝撃がかからず、ねじ山部分が損耗することがない。しかも、切欠部の切欠縁部がボルト軸部の谷部に嵌り込むようになるから、この規制によりボルトの軸方向の動きが阻止され、ボルトが抜け出すこともない。
【００１８】
請求項４の発明に係るボルト係止用仮止め具では、請求項１において、ボルト係止用空所は、取付ベースに形成されたボルト挿通孔と、このボルト挿通孔に連なり上記添装状態で貫通孔に対応する位置にまで延びるボルト係止用長孔部によって形成されている。
この構成によれば、先ずボルト挿通孔にボルトの軸部を挿通させ、その後長孔部分内を横移動させる。これにより、長孔部分の開口縁部がボルト軸部の谷部に嵌り込むようになり、ボルトのねじ山を損耗させるようなストレスがかからず、この規制によりボルトの軸方向の動きが阻止され、ボルトが抜け出すこともない。
【００１９】
請求項５に係る発明の係るパイプ支持バンドの仮止め具は、請求項１乃至４のいずれかにおいて、取付片部用ガイド部の曲成基部に、上記係止爪が取付ベースに向くよう折曲形成されている。従って、取付片部用ガイド部によって誘導された取付片部の上下端は、最終的には、係止爪表面を滑り、その裏側にはまり込む。そのため、取付片部用ガイド部にそって取付片部の上下端を移動させるという簡易な作業で、係止爪を取付片部に導入して仮止めすることができる。
【００２０】
請求項６の発明に係るパイプ支持バンドの仮止め具は、請求項１乃至５のいずれかにおいて、上記片部には、取付ベースとにより上記一方の取付片部を把持する第２の係止爪が更に設けられていることを特徴とする。従って、取付ベースを一方の取付片部に添装する際、この第２の係止爪が一方の取付片部に係止され、取付ベースが一方の取付片部から外れ落ちることを防止できる。
【００２１】
請求項７の発明に係るパイプ支持バンドの仮止め具は、請求項１乃至６のいずれかにおいて、上記ボルト挿通孔の外側にボルト頭部の廻り止め部が形成されていることを特徴とする。これによれば、ナットを締め付ける際に、ボルトの頭部が廻り止め部によりその回動が規制され、いわゆる共廻りが生じないから、ナットを回転操作するだけで足部材を挟み込んだ一対の取付片部を容易且つ素早く締め付けでき、作業効率を更に高めることができる。
【００２２】
請求項８の発明に係るパイプ支持バンドの仮止め具は、請求項１乃至７のいずれかにおいて、上記取付ベースの取付片部又は足部材添装面側に隆起突部が形成されていることを特徴とする。このような。隆起突部は、ボルト挿通孔の周辺部分に形成することが望ましく、ボルト・ナットにより締結したとき、この隆起突部が取付ベースと取付片部間或いは取付ベースと足部材間に存在することになるから、締結時の締付力によりこの隆起突部に圧縮力が作用する。従って、その反力が皿ばね或いはスプリングワッシャのような機能を奏し、ボルトの緩みを抑制する。
【００２３】
【発明の実施の形態】
以下に、本発明の第１の実施形態について説明する。図１は、第１実施形態に係るパイプ支持バンドの仮止め具のパイプ取付要領を示す分解斜視図、図２はこのような本発明の構造例を示す斜視図、図３は同取付要領を示す縦断面図である。
【００２４】
図１におけるパイプ支持バンドＡは、一般的な従来品であり、図中想像線で示すパイプＰを抱持すべく、基部がヒンジピン１０を介して結合され開閉する２つ割バンド本体１、１の先側一対の取付片部１１、１１で、基端を建屋の壁面等に固定した足部材２の足本体２１を挟み込み、両者をボルト３とナット４で締結固着するようにしている。一対の取付片部１１、１１には、互いに対応する位置に、ボルト３の軸部３１を挿通する２個の貫通孔１２、１２が開設され、足部材２の足本体２１には、ボルト３の軸部３１を挿通する貫通孔としての長孔２２が開設されている。
【００２５】
パイプ支持バンドＡは、図１のようにパイプＰの周体に２つ割バンド本体１、１をして抱持され、一対の取付片部１１、１１を足部材２の足本体２１を挟み込むようにして重合させ、ボルト３及びナット４により取付片部１１、１１が足部材２に締結・固着されるが、この締結・固着の際に本発明の仮止め具５が使用される。
【００２６】
図例の仮止め具５は、ばね鋼、ステンレス板、アルミ板、銅板等の板金材からなり、取付片部１１、１１の一方の片面に添装される取付ベース５０と、この取付ベース５０に上記２つの貫通孔１２、１２と対応する位置に形成されたボルト係止用孔部５１、５１と、この取付ベース５０の上端及び下端から略垂直方向に延設され、他方の取付片部１１に係止する係止爪５２ａ、５２ａを先端に設けた片部５２、５２とにより基本的に構成されている。
【００２７】
上記ボルト係止用孔部５１、５１の開口縁部には、内径がボルト軸部３１の山径よりやや小さい短筒部５３、５３がボルト挿通方向に突設されている。また、片部５２、５２の取付ベース５０側に、取付ベース５０が添装される取付片部１１に係止する第２の係止爪５２ｂ、５２ｂが切起こし形成されている。更に、取付ベース５０には、ボルト挿通用孔部５１、５１の近傍位置にボルト頭部３２の側辺に当接するボルト３の廻り止め部５４…が折曲げ形成されている。
【００２８】
このような仮止め具５を用い、パイプ支持バンドＡによりパイプＰを建屋の壁面（不図示）に配設する要領について、図１及び図３に基づき説明する。先ず、図３（ａ）に示すように、仮止め具５のボルト挿通用孔部５１にボルト３の軸部３１を挿通させる。この場合、ボルト係止用孔部５１の開口縁部に突設された短筒部５３の内径は、ボルト軸部３１の山径よりやや小さくされているから、ボルト３はボルト係止用孔部５１に叩き込むように圧入される。ボルト係止用孔部５１には鋭利なエッジ部等が存在せず、短筒部５３がガイド筒として機能するから、この圧入の際にねじ山部が損耗するようなことがない。しかも、ボルトの挿通状態においては、短筒部５３の拘束作用によってボルト３が抜け落ちることがない。
【００２９】
次いで、図２のようにパイプＰの周体に仮抱持させた２つ割バンド本体１、１の一方の取付片部１１に、仮止め具５を係止させる。即ち、図３（ｂ）に示すように、取付片部１１に開設された貫通孔１２にボルト３の軸部３１を挿通させながら、第２の係止爪５２ｂ、５２ｂを押し開くようにして取付ベース５０を取付片部１１の片面側に添装させる。この状態では、取付ベース５０の裏面と弾性復元した第２の係止爪５２ｂ、５２ｂとにより、取付片部１１が挟まれるようになり、仮止め具５は手離しても脱落する懸念なく取付片部１１に安定的に係止される。この状態で施工現場などに持ち運ばれる。
【００３０】
更に、図３（ｃ）に示すように、足部材２の長孔２２にボルト３の軸部３１を挿通させ、引き続き、他方の取付片部１１をその貫通孔１２にボルト３の軸部３１を挿通させながら、係止爪５２ａ、５２ａを押し開くようにして足本体２１の片面側に添装するよう押し込む。この状態では、係止爪５２ａ、５２ａが、弾性復元して、上記他方の取付片部１１の外面側に当接するよう位置するから、この取付片部１１及び足本体２１が外れることがなく、取付片部１１、１１及び足本体２１の重合状態が維持される。尚、他方の取付片部１１を重合させる作業において、上記２つ割バンド本体１、１の一方が上下にずれていることがあるが、このような場合でも、ボルト３の軸部３１が短筒部５３による支持部を支点として揺動が許容されているから、ボルト軸部３１の貫通孔１２への誘導がし易く、作業が効率的になされる。
【００３１】
上記のように重合状態を維持した状態で、図３（ｃ）に示すように、ナット４をボルト３の軸部３１に螺装締結がなされる。この場合、取付片部１１、１１及び足本体２１は、仮止め具５およびボルト３により重合状態が維持されており、しかもボルト３の頭部３２が廻り止め部５４に当接してその廻り止め（共廻り止め）がなされているから、作業者は、その両手をパイプＰの抱持とナット４の締付操作に供することができ、極めて安全且つ効率的にその作業を行うことができる。
図４は、ボルト挿通用孔部５１及び短筒部５３の概略的説明図であり、（ａ）は平面図、（ｂ）は（ａ）にけるＸ−Ｘ線断面図、（ｃ）はその変形例を示す。図４（ａ）、（ｂ）において、ボルト係止用孔部５１の開口縁部に突設された短筒部５３は、内径が先行縮径するテーパー状に形成されており、その最小内径ｄがボルトの山径よりやや小さく設定されている。このようにテーパー状に形成されていると、ガイド機能が付加され、ボルトの圧入挿通の際の作業性が向上する。この短筒部５３には放射状の切込部（スリット）５３ａが複数周方向に略等間隔で形成されている。この切込部５３ａは、ボルトの圧入の際、短筒部５３の壁部が拡開するのを助長し、ボルトの圧入挿通をし易くするもので、このような線状のものに限らず、星形や花形に形成することも可能である。
【００３２】
図４（ｃ）は、短筒部５３が直状であることを示し、その内径ｄがやはりボルトの山径よりやや小さく設定されている。この例の場合は、図４（ｂ）のようなテーパー状のものに比べボルトの挿入ガイド機能はやや劣るが、同様に好ましく採用される。このような短筒部５３は、仮止め具５を板金加工により製する場合はバーリング加工によって形成される。
【００３３】
図５（ａ）（ｂ）（ｃ）は、上記ボルトの廻り止め部５４の変形例を示す。図５（ａ）の廻り止め部５４ａは、取付ベース５０に２条の切込みを入れ、絞り加工によりブリッジ状に隆起させたものである。図５（ｂ）の廻り止め部５４ｂは、取付ベース５０に切起こし加工を施し舌片状に形成したものである。図例の廻り止め部５４ｂは斜めに切起こされたものであるが、取付ベース５０に対して略垂直に切起こされたものであってもよい。また、図５（ｃ）の廻り止め部５４ｃは、取付ベース５０の上下辺部を断面半円形の突状に曲成したものである。
【００３４】
これら廻り止め部５４ａ、５４ｂ、５４ｃは、ボルト係止用孔部５１にボルトを挿通した状態では、ボルト頭部の側部が当接し、ナットの螺装締結作業時において、ボルトの共廻りを阻止するべく機能する。図例ではいずれも上下一対形成した例が示されているが、いずれか一方のみとすること、或いは３個以上設けることも可能である。形状も図例のものに限定されず他の形状も採用可能である。
【００３５】
上記のような締結作業によって、パイプ支持バンドＡはパイプＰを抱持し、この先側の取付片部１１、１１が足本体２１を挟み込むように足部材２に締結固着される。ボルト３及びナット４による締結状態では、上記短筒部５３が取付ベース５０と取付片部１１との間に挟圧状態で介在されることになるから、この隆起突部としての短筒部５３の復元反力により、皿ばね或いはスプリングワッシャのような機能が発現され、取付片部１１、１１及び足本体２１の強固な緊合重合状態が維持される。尚、このような皿ばね等の機能を更に助長させる為に、取付ベース５０の取付片部１１添装側面に隆起突部を形成することも望ましい。
【００３６】
図１において、２点鎖線で示す部分５５、５５は、上記ボルト３及びナット４による締結後、上下片部５２、５２を含んで破断除去する為に形成された破断促進部を示す。本発明に係る仮止め具５は、上記のように取付片部１１、１１をボルト３及びナット４により足部材２に重合固着させる際に、文字通りこれら部材同士を仮止めする為に用いられるもので、元来重合固着後は不要とされるものである。しかも、その構造上、特に上下の片部５２、５２が突出するため、これに手などを引っ掛けて怪我をする恐れがあり、また仮止め具５が目立ち見映えもよくない。更に、雨水が溜まり易く、錆の原因ともなり、劣化が促進されることにもなる。
【００３７】
上記破断促進部５５、５５は、このような難点を極力払拭する為に形成されたもので、図６（ａ）〜（ｈ）は、その種々の形成態様を示すものである。図６（ａ）の破断促進部５５ａは、取付ベース５０の肉厚を線状に薄くする小凹溝によってその幅方向全幅に亘って形成されたものであり、図６（ｂ）の破断促進部５５ｂは、取付ベース５０の幅方向中央部を残してこの小凹溝を形成したものである。
【００３８】
また、図６（ｃ）の破断促進部５５ｃは、上記小凹溝と取付ベース５０の両側辺部からの切込みとを併用したものであり、図６（ｄ）の破断促進部５５ｄは、小凹溝と穿孔とを併用したもの、図６（ｅ）の破断促進部５５ｅは、取付ベース５０の両側辺部からの切込みのみによるものである。更に、図６（ｆ）の破断促進部５５ｆは、切込みと穿孔とを併用したもの、図６（ｇ）の破断促進部５５ｇは、楕円もしくは長円状の長孔によるもの、そして図６（ｈ）の破断促進部５５ｈは、多数の小穿孔によりノッチ状に形成したものを夫々示す。
【００３９】
このような破断促進部５５ａ〜ｈは、取付ベース５０の肉厚を薄くし、或いは実質的に取付ベース５０の幅を狭めるものであり、上記のように取付片部１１、１１をボルト３及びナット４により足部材２に重合固着させた後、上下の片部５２、５２を反り曲げるようにすれば、これら破断促進部５５ａ〜ｈから片部５２、５２が破断除去される。従って、上記重合固着状態においては、仮止め具５は、取付ベース５０のみが残り、突出する部分が除去されるから、上記のように手等を引っ掛ける懸念がなく、また見映えもシンプルとなり、更に雨水の溜まり部分が少なくなって、錆の発生や劣化の促進も少なくなる。
【００４０】
図１では、更に上下片部５２、５２の先側に２点鎖線で示す折曲促進部５６、５６が形成されている。この折曲促進部５６、５６は、上記破断促進部５５ａ〜ｈにより片部５２、５２を破断除去しないまでも、上下片部５２、５２の先側突出部分を、他方の取付片部１１の外側面に、手やハンマー等により叩き込み折曲展装させる為のものである。
【００４１】
この折曲促進部５６、５６としては、図６に示す破断促進部５５ａ〜ｈと同じような形成態様が採用可能である。上記と同様各部材を重合固着させた後、片部５２、５２の先側を殴打し、折曲促進部５６、５６から折曲して他方の取付片部１１の外側面に展装させると、上記同様突出部分がなくなり、手等を引っ掛ける懸念がなく、また見映えもシンプルとなる。
更に、図１〜図３では、上下一対の片部５２、５２の先側部分が互いに開くよう折曲されて、前記パイプ支持バンドＡにおける他方の取付片部１１を導入し易くする為のガイド部５７、５７とされている。このようなガイド部５７、５７を設けると、取付片部１１を導入し係止爪５２ａ、５２ａに係止させて仮止めする作業がし易く、作業の合理化が図られる。
【００４２】
また、破断促進部５５、５５から片部５２、５２を破断除去する場合や、折曲促進部５６，５６から片部５２，５２の先端を折り曲げて、他方の取付片部１１の外側面に展装させる際には、このガイド部５７、５７が把持部となるので、摘み易く、叩き易くなり、破断除去、折曲展装作業等の施工性が大変良好となる。
【００４３】
また、このような構成の仮止め具５は、取付ベース５０の取付片部１１側には、ボルト挿通孔５１の近傍部に複数の隆起突部５８…が形成されており、図３のようにボルト３及びナット４により螺装締結する際、この隆起突部５８…が取付ベース５０と取付片部１１との間に介在し、両者によって挟圧されることになるから、その復元反力により、皿ばね或いはスプリングワッシャのようなボルトの緩みを防止する機能が発現され、上記緊合固着状態が長く維持される。
図７は、第１の実施形態に係る仮止め具５の変形例を示す斜視図であり、取付ベース５０の上下端から、断面半円形の突条に曲成して、上下並行に片部５２、５２を延設したものである。この断面半円形の突条部分５４ｄ、５４ｄの間隔は、六角ボルト頭部の対向辺間距離に略等しいかやや大きく設定されている。従って、前述と同様にボルトをボルト係止用孔部５１、５１に挿通し、取付片部１１を足部材に重合しナットにより螺装締結する際、ボルトの頭部がこの突条部分５４ｄ、５４ｄ間に嵌り込むようになるので、これによりボルトの回転が規制され、ボルトの廻り止め機能を奏することになる。
【００４４】
また、この突条部分５４ｄ、５４ｄの曲成基部５５ｉ、５５ｉは、曲成加工の際に応力が集中するので脆くなっており、上記ナットにより螺装締結し後、片部５２、５２を反り曲げるようにすれば、この曲成基部５５ｉ、５５ｉより片部５２、５２が破断除去可能となる。特に、ナットによる螺装締結時にボルト頭部の回転応力が突条部分５４ｄ、５４ｄに付加され、この応力が曲成基部５５ｉ、５５ｉに更に蓄積されるから、より破断除去がし易くなる。このように、曲成基部５５ｉ、５５ｉは、上記の破断促進部と同様の機能を奏するので、この例の場合は別途破断促進部を形成することを要しないのである。その他の構成は、上記と同様であるので、共通部分には同一の符号を付し、その説明を割愛する。
【００４５】
図８は、第１の実施形態に係る仮止め具５の更なる変形例を示す斜視図であり、取付ベース５０が、一方の取付片部１１と足本体２１と間に添装されるタイプの仮止め具５であることを示す。上記各例では仮止め具５の取付ベース５０が取付片部１１の外側面に添装されるが、この場合折り曲げ延設された片部５２、５２と取付片部１１との間に雨水が溜まり易く、錆の発生の原因となり、或いは劣化を促進することが予想される。また、取付片部１１の外側面にはパイプ支持バンドＡの品番やメーカー名等が標示されていることが多く、この面が取付ベース５０で覆われてしまうと、現場合せに支障を来たしたり、或いは商品の宣伝効果が減退したりすることにもなる。
【００４６】
本例では、取付ベース５０の上下端から、片部５２、５２の延設方向とは反対の方向に、第２の係止爪５２ｂ、５２ｂを突出するよう設け、これにより仮止め具５を取付片部１１の一方に係止するようにしている。従って、この取付片部１１の上辺部には第２の係止爪５２ｂのみが存在し、空間部分が多くなるからこの部分に雨水等が溜まりにくくなる。また、標示等がなされる取付片部１１の外側面が取付ベース５０で覆われず、露出部分が多いからこの標示等が読み取れる状態に維持される。
【００４７】
図９は、図８に示す仮止め具５を用いて取付片部１１、１１を足部材２に重合固着する要領を示す図である。この場合、先ず、一方の取付片部１１の貫通孔１２にボルト３の軸部３１を挿通させ、次いで取付ベース５０のボルト係止用孔部５１及び短筒部５３にボルト３の軸部３１を圧入する。その後は、上記と同じ要領で足部材２の足本体２１及び他方の取付片部１１の夫々の長孔２２及び貫通孔１２にボルト３の軸部３１を挿通させ、図９のように仮止め具５により取付片部１１、１１及び足本体２１を仮止めする。そして、ナット４をボルト３の軸部３１に螺装締結させ、これら部材を緊合固着状態とする。
【００４８】
この仮止め具５の取付ベース５０には図８に示すようにボルト係止用孔部５１の近傍部に複数の隆起突部５８…が形成されており、図９のようにボルト３及びナット４により螺装締結する際、この隆起突部５８…が取付ベース５０と取付片部１１との間に介在し、両者によって挟圧されることになるから、その復元反力により、皿ばね或いはスプリングワッシャのようなボルトの緩みを防止する機能が発現され、上記緊合固着状態が長く維持される。その他の構成は上記の例と同様であるので、ここでも共通部分には同一の符号を付しその説明を割愛する。
【００４９】
図１０は、本発明の第２の実施形態の仮止め具５の構造例を示す斜視図である。このものでは、先述したボルト係止用孔部５１，５１に代わり、取付ベース５０の側面部から上記２つの貫通孔１２、１２と対応する位置にまで延びるよう切欠き形成されたボルト係止用切欠部５１’、５１’を設けており、このボルト係止用切欠部５１’、５１’の切欠幅寸法ｄは、ボルト軸部３１の山径よりやや小さく且つ谷径よりやや大きく設定されていることを特徴とする。
【００５０】
このような構造では、仮止め具５を取付片部１１，１１に取り付ける際、ボルト３の軸部をボルト係止用切欠部５１’にその切欠開口部より横移動させて係止させる。この場合、ボルト係止用切欠部５１’の上記切欠幅寸法ｄは、ボルト軸部３１の山径よりやや小さく且つ谷径よりやや大きくされているから、ボルト係止用切欠部５１’の切欠縁部がボルト軸部３１の谷部に嵌り込むように移動して、ボルト３が所定の位置に係止される。この係止によってボルト３が抜け落ちることがなく、しかもボルト３のねじ山には何等衝撃がかからないから、ねじ山部が損耗するようなことがない。
【００５１】
また、このような構成でも、片部５２，５２の先端には、互いに開くように折曲形成された取付片部用ガイド部５７，５７があるため、係止爪５２ａ，５２ａを取付片部１１，１１に導入して仮止めする作業が容易にできる。また、折曲促進部５６や破断促進部５５の存在により、片部５２の折り曲げ作業、切り取り除去作業が容易にできる。
【００５２】
図１１は、第２の実施形態の変形例を示し、取付ベース５０の上下端から、断面半円形の突条に曲成して、上下並行に片部５２、５２を延設したものである。この断面半円形の突条部分５４ｄ、５４ｄの間隔は、六角ボルト頭部の対向辺間距離に略等しいかやや大きく設定されている。従って、前述と同様にボルトをボルト係止用孔部５１、５１に挿通し、取付片部を足部材に重合しナットにより螺装締結する際、ボルトの頭部がこの突条部分５４ｄ、５４ｄ間に嵌り込むようになるので、これによりボルトの回転が規制され、ボルトの廻り止め機能を奏することになる。
【００５３】
また、この突条部分５４ｄ、５４ｄの曲成基部５５ｉ、５５ｉは、曲成加工の際に応力が集中するので脆くなっており、上記ナットにより螺装締結し後、片部５２、５２を反り曲げるようにすれば、この曲成基部５５ｉ、５５ｉより片部５２、５２が破断除去可能となる。特に、ナットによる螺装締結時にボルト頭部の回転応力が突条部分５４ｄ、５４ｄに付加され、この応力が曲成基部５５ｉ、５５ｉに更に蓄積されるから、より破断除去がし易くなる。このように、曲成基部５５ｉ、５５ｉは、上記の破断促進部と同様の機能を奏するので、この例の場合は別途破断促進部を形成することを要しないのである。
【００５４】
このものは、先例と同様に、上下一対の片部５２、５２の先側部分が互いに開くよう折曲されて、前記パイプ支持バンドＡにおける他方の取付片部１１を導入し易くする為のガイド部５７、５７とされている。したがって、取付片部１１を導入し係止爪５２ａ、５２ａに係止させて仮止めする作業がし易く、作業の合理化が図られる。
その他の構成は、上記と同様であるので、共通部分には同一の符号を付し、その説明を割愛する。
【００５５】
図１２（ａ）〜（ｆ）は、ボルト係止用切欠部５１’の種々の形成態様を示すものであり、図１２（ａ）のボルト係止用切欠部５１’ａは、取付ベース５０の側辺部から開口幅ｄで切欠かれ、最奥部の径がｄの半円部分がボルトの係止部とされる。ボルトの軸部はこの切欠開口部から横移動されてボルト係止用切欠部５１’ａに挿入されて、最奥部の半円部分に至り上記のように軸方向の抜けが阻止された状態で係止される。
【００５６】
図１２（ｂ）のボルト係止用切欠部５１’ｂは、上記同様切欠かれ最奥部にはボルトの山径より小さいが上記ｄよりやや大きい径ｄ１の円形部分がボルトの係止部とされる。この場合、上記と同様にボルトの軸部が挿入されるが、一旦この円形部分にボルト軸部が収まると、ボルトの軸方向の抜けが防止される上に、横移動も拘束されることになる。
【００５７】
図１２（ｃ）のボルト係止用切欠部５１’ｃは、（ａ）のボルト係止用切欠部５１’ａに加え、切欠対向内辺部に小突起を設け、最奥部の係止部に係止されているボルトの横移動を規制せんとするものである。図１２（ｄ）（ｅ）（ｆ）のボルト係止用切欠部５１’ｄ、５１’ｅ、５１’ｆは、最奥部の係止部に遠心方向の切込みを形成したものである。このような切込みが形成されている場合、ボルト軸部の谷部に対する係止位置が少し軸部の先側であっても、ナットによる締付の際に係止位置の頭部側への移動を許容し、その締付強度の低下を防止することができる。
【００５８】
図１３は、取付ベース５０に形成されるボルト係止手段の他例を示すものであり、ボルト挿通孔５１Ａと、このボルト挿通孔５１Ａに連なり上記添装状態で前記取付片部の貫通孔に対応する位置にまで延びるボルト係止用長孔部分５１Ｂとよりなる。ボルト挿通孔５１Ａの径ｄ２はボルト軸部の山径より大とされ、また長孔部分５１Ｂの幅寸法ｄは、上記と同様ボルト軸部の山径よりやや小さく且つ谷径よりやや大とされている。従って、ボルトの軸部をボルト挿通孔５１Ａに挿通し、その後長孔部分５１Ｂに沿って横方向（図では左方向）に移動させると、長孔部分５１Ｂの開口縁部がボルト軸部の谷部に嵌り込み、ボルトは軸方向への抜けが阻止される状態で長孔部分５１Ｂに係止される。
【００５９】
図１４は、本発明の第２の実施形態の更なる変形例を示す図である。このものは、取付ベース５０が、一方の取付片部１１と足本体２１との間に添装されるタイプの仮止め具５であることを示す。
【００６０】
これまで説明したものでは、仮止め具５の取付ベース５０が取付片部１１の外側面に添装されるが、この場合折り曲げ延設された片部５２、５２と取付片部１１との間に雨水が溜まり易く、錆の発生の原因となり、或いは劣化を促進することが予想される。また、取付片部１１の外側面にはパイプ支持バンドＡの品番やメーカー名等が標示されていることが多く、この面が取付ベース５０で覆われてしまうと、現場合せに支障を来たしたり、或いは商品の宣伝効果が減退したりすることにもなる。
【００６１】
本例では、取付ベース５０の上下端から、片部５２、５２の延設方向とは反対の方向に、第２の係止爪５２ｂ、５２ｂを突出するよう設け、これにより仮止め具５を取付片部１１の一方に係止するようにしている。従って、この取付片部１１の上辺部には第２の係止爪５２ｂのみが存在し、空間部分が多くなるからこの部分に雨水等が溜まりにくくなる。また、標示等がなされる取付片部１１の外側面が取付ベース５０で覆われず、露出部分が多いからこの標示等が読み取れる状態に維持される。なお、この第２の係止爪５２ｂ，５２ｂは、係止構造によっては不要とすることもできる。
【００６２】
また、取付ベース５０には、２種のボルト係止手段が形成されている。即ち、図における取付ベース５０の右側辺部から開口幅が大きく（ボルト軸部の山径より大きく）切欠かれた切欠部分５１ｇ及びこれに連なるボルト係止用切欠部５１と、ボルト挿通孔５１Ａ及びこれに連なるボルト係止用長孔部分５１Ｂとを備える。切欠部分５１ｇは、その開口幅がボルト挿通孔５１Ａの径と略同じとされ、形状は略半円形である。
【００６３】
図１５は、図１４に示す仮止め具５を用いて取付片部１１、１１を足部材２に重合固着する要領を示す図である。この場合、先ず、一方の取付片部１１の貫通孔１２にボルト３の軸部３１を挿通させ、次いで取付ベース５０の切欠部分５１ｇ及びボルト挿通孔５１Ａにボルト３の軸部３１を挿入する。その後仮止め具５を横移動させて、ボルト３の軸部３１をボルト係止用切欠部５１’及びボルト係止用長孔部分５１Ｂに係止させる。
【００６４】
この状態では、両ボルト３は夫々ボルト係止用切欠部５１’及びボルト係止用長孔部分５１Ｂに係止されているから、軸方向の抜けが阻止される。その後は、上記と同じ要領で足部材２の足本体２１及び他方の取付片部１１の夫々の長孔２２及び貫通孔１２にボルト３の軸部３１を挿通させ、図１５のように仮止め具５により取付片部１１、１１及び足本体２１を仮止めする。そして、ナット４をボルト３の軸部３１に螺装締結させ、これら部材を緊合固着状態とする。
【００６５】
この仮止め具５の取付ベース５０には図１４に示すようにボルト係止用切欠部５１’及びボルト係止用長孔部分５１Ｂの近傍部に複数の隆起突部５８…が形成されており、図１５のようにボルト３及びナット４により螺装締結する際、この隆起突部５８…が取付ベース５０と取付片部１１との間に介在し、両者によって挟圧されることになるから、その復元反力により、皿ばね或いはスプリングワッシャのようなボルトの緩みを防止する機能が発現され、上記緊合固着状態が長く維持される。また、片部５２、５２を取付ベース５０に対して図のようにＲを小さく屈曲形成するようにすれば、この屈曲部分５５に応力が集中するから、この屈曲部分５５を前記の破断促進部として機能させることができる。その他の構成は上記の例と同様であるので、ここでも共通部分には同一の符号を付しその説明を割愛する。
【００６６】
最後に、本発明に係る仮止め具５は本実施形態では板金材で構成する例について述べたが、樹脂の成形品により構成することも可能である。また、第２の係止爪５２ｂ，５２ｂは、仮止め具５の一方の取付片部１１への係止構造により不要とすることができる。更に、建屋の壁面にパイプを配設施工する例について述べたが、天井面等に配設施工する場合にも適用され得ることは言うまでもない。
【００６７】
【発明の効果】
請求項１乃至４の発明によれば、仮止め具の係止爪を、パイプ支持バンドの取付片部に導入して仮止めする際には、取付片部の上下端のそれぞれが、取付片部用ガイド部によって誘導されるため、係止爪を取付片部に導入しやすくできる。そのため、作業性がよく作業の合理化が図れ、また、高所作業における安全面にも寄与できる。
【００６８】
特に、請求項３の発明によれば、ボルト係止用空所は、取付ベースの側辺部より切り欠かれ添装状態で貫通孔に対応する位置にまで延びるボルト係止用切欠部によって形成されているので、パイプの配設作業において、ボルト係止用切欠部にボルトを係止させる場合、ボルトの軸部をボルト係止用切欠部の切欠開口部より横移動させて係止させるので、ボルトのねじ山に何等衝撃がかからず、ねじ山部分が損耗することがない。しかも、切欠部の切欠縁部がボルト軸部の谷部に嵌り込むようになるから、この規制によりボルトの軸方向の動きが阻止され、ボルトが抜け出すこともない。
【００６９】
また、請求項４の発明によれば、ボルト係止用空所は、取付ベースに形成されたボルト挿通孔と、このボルト挿通孔に連なり上記添装状態で貫通孔に対応する位置にまで延びるボルト係止用長孔部によって形成されているので、長孔部分の開口縁部がボルト軸部の谷部に嵌り込むようになり、ボルトのねじ山を損耗させるようなストレスがかからず、この規制によりボルトの軸方向の動きが阻止され、ボルトが抜け出すこともない。
【００７０】
請求項５の発明によれば、パイプ支持バンドの仮止め具は、取付片部用ガイド部によって誘導された取付片部の上下端は、最終的には、係止爪表面を滑り、その裏側にはまり込む。そのため、取付片部用ガイド部にそって取付片部の上下端を移動させるという簡易な作業で、係止爪を取付片部に導入して仮止めすることができる。
【００７１】
請求項６の発明によれば、上記片部には、取付ベースとにより上記一方の取付片部を把持する第２の係止爪が更に設けられているので、取付ベースを一方の取付片部に添装する際、この第２の係止爪が一方の取付片部に係止され、取付ベースが一方の取付片部から外れ落ちることを防止できる。
【００７２】
請求項７の発明によれば、上記ボルト挿通孔の外側にボルト頭部の廻り止め部が形成されているので、ナットを締め付ける際に、ボルトの頭部が廻り止め部によりその回動が規制され、ナットを回転操作するだけで足部材を挟み込んだ一対の取付片部を容易且つ素早く締め付けでき、作業効率を更に高めることができる。
【００７３】
請求項８の発明によれば、上記取付ベースの取付片部又は足部材添装面側に隆起突部が形成されているので、ボルト・ナットにより締結したとき、この隆起突部が取付ベースと取付片部間或いは取付ベースと足部材間に存在することになり、締結時の締付力によりこの隆起突部に圧縮力が作用する。従って、その反力が皿ばね或いはスプリングワッシャのような機能を奏し、ボルトの緩みを抑制する。

[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a first embodiment of the present invention will be described. FIG. 1 is an exploded perspective view showing a pipe mounting procedure of a temporary fixing device of the pipe support band according to the first embodiment, FIG. 2 is a perspective view showing such a structural example of the present invention, and FIG. FIG.

The pipe supporting band A in FIG. 1 is a general conventional product, and is divided into two main bands 1, 1 which are opened and closed by a base connected via a hinge pin 10 so as to hold a pipe P indicated by an imaginary line in the figure. The foot body 21 of the foot member 2 whose base end is fixed to a wall surface of a building or the like is sandwiched between the pair of mounting pieces 11, 11 on the front side, and both are fastened and fixed with bolts 3 and nuts 4. Two through holes 12, 12 through which the shaft 31 of the bolt 3 is inserted are formed in the pair of mounting pieces 11, 11 at positions corresponding to each other. A long hole 22 is formed as a through hole through which the shaft portion 31 is inserted.
[0025]
As shown in FIG. 1, the pipe support band A is held with the band body 1, 1 halved around the pipe P, and the pair of attachment pieces 11, 11 sandwich the foot body 21 of the foot member 2. The mounting pieces 11, 11 are fastened and fixed to the foot member 2 by the bolts 3 and the nuts 4 as described above, and the temporary fixing tool 5 of the present invention is used for this fastening and fixing.
[0026]
The temporary fixing tool 5 in the illustrated example is made of a sheet metal material such as a spring steel, a stainless steel plate, an aluminum plate, or a copper plate, and is provided with a mounting base 50 attached to one surface of the mounting pieces 11, 11. Bolt holes 51, 51 formed at positions corresponding to the two through holes 12, 12, and extending substantially vertically from the upper and lower ends of the mounting base 50, and the other mounting piece portion It is basically constituted by locking portions 52a, 52a, 52a, 52a, 52a, 52a, 52a, 52b, 52a, 52b, 52a, 52b, 52a, 52b.
[0027]
At the opening edges of the bolt locking holes 51, short cylindrical portions 53, 53 whose inner diameter is slightly smaller than the mountain diameter of the bolt shaft 31, protrude in the bolt insertion direction. Further, on the mounting base 50 side of the pieces 52, 52, second locking claws 52b, 52b which are locked to the mounting piece 11 to which the mounting base 50 is attached are cut and raised. Further, the mounting base 50 is formed with bending stoppers 54 for the bolts 3 that abut against the side of the bolt head 32 at positions near the bolt insertion holes 51, 51.
[0028]
A procedure for disposing a pipe P on a wall surface (not shown) of a building by using a pipe support band A using such a temporary fixing tool 5 will be described with reference to FIGS. 1 and 3. First, as shown in FIG. 3A, the shaft 31 of the bolt 3 is inserted into the bolt insertion hole 51 of the temporary fastener 5. In this case, since the inside diameter of the short cylindrical portion 53 protruding from the opening edge of the bolt locking hole 51 is slightly smaller than the mountain diameter of the bolt shaft portion 31, the bolt 3 is formed in the bolt locking hole 51. It is press-fitted so as to be driven into the portion 51. Since there is no sharp edge portion or the like in the bolt locking hole 51 and the short cylindrical portion 53 functions as a guide cylinder, the thread portion is not worn during this press-fitting. Moreover, in the inserted state of the bolt, the bolt 3 does not come off due to the restraining action of the short cylindrical portion 53.
[0029]
Next, as shown in FIG. 2, the temporary fixing member 5 is locked to one of the attachment pieces 11 of the split band main bodies 1 and 1 temporarily held on the peripheral body of the pipe P. That is, as shown in FIG. 3B, the second locking claws 52b are pushed open while the shaft 31 of the bolt 3 is inserted through the through hole 12 formed in the mounting piece 11. The mounting base 50 is attached to one side of the mounting piece 11. In this state, the mounting piece 11 is sandwiched between the back surface of the mounting base 50 and the second elastic claw 52b, 52b that has been elastically restored, and the temporary fixing tool 5 is mounted without fear of falling off even if it is released. The piece 11 is stably locked. In this state, it is carried to a construction site or the like.
[0030]
Further, as shown in FIG. 3C, the shaft 31 of the bolt 3 is inserted into the long hole 22 of the foot member 2, and then the other mounting piece 11 is inserted into the through hole 12 of the bolt 3. , The locking claws 52a, 52a are pushed open so as to be attached to one side of the foot body 21. In this state, the locking claws 52a, 52a are elastically restored and are positioned so as to come into contact with the outer surface side of the other mounting piece 11, so that the mounting piece 11 and the foot main body 21 do not come off. The superposed state of the attachment pieces 11, 11 and the foot body 21 is maintained. In the operation of overlapping the other mounting piece 11, one of the split band bodies 1, 1 may be vertically displaced. Even in such a case, the shaft 31 of the bolt 3 is short. Since swinging is allowed with the support portion of the cylindrical portion 53 as a fulcrum, the bolt shaft portion 31 can be easily guided to the through-hole 12 and work can be performed efficiently.
[0031]
With the superimposed state maintained as described above, the nut 4 is screwed and fastened to the shaft portion 31 of the bolt 3 as shown in FIG. In this case, the attachment pieces 11, 11 and the foot main body 21 are maintained in a superimposed state by the temporary fixing tool 5 and the bolt 3, and the head 32 of the bolt 3 abuts against the detent part 54 to stop the detent. Since the (rotation stop) is performed, the operator can use both hands for holding the pipe P and tightening the nut 4, and can perform the operation extremely safely and efficiently.
4A and 4B are schematic explanatory views of the bolt insertion hole 51 and the short cylindrical portion 53, wherein FIG. 4A is a plan view, FIG. 4B is a sectional view taken along line XX in FIG. The modified example will be described. 4 (a) and 4 (b), the short cylindrical portion 53 protruding from the opening edge of the bolt locking hole 51 is formed in a tapered shape whose inner diameter is reduced in advance, and its minimum inner diameter is d is set slightly smaller than the diameter of the bolt. When formed in such a tapered shape, a guide function is added, and workability at the time of press-fitting and inserting a bolt is improved. A plurality of radial cut portions (slits) 53a are formed in the short cylindrical portion 53 at substantially equal intervals in the circumferential direction. The cut portion 53a facilitates the expansion of the wall of the short cylindrical portion 53 when the bolt is press-fitted, and facilitates the press-fit insertion of the bolt, and is not limited to such a linear shape. , A star or a flower can also be formed.
[0032]
FIG. 4C shows that the short tubular portion 53 is straight, and the inner diameter d is set slightly smaller than the mountain diameter of the bolt. In the case of this example, the bolt insertion guide function is slightly inferior to that of the tapered one as shown in FIG. Such a short tubular portion 53 is formed by burring when the temporary fixing tool 5 is manufactured by sheet metal processing.
[0033]
FIGS. 5A, 5B, and 5C show modified examples of the above-described bolt rotation stopper 54. FIG. The rotation stopper 54a in FIG. 5 (a) is obtained by making two cuts in the mounting base 50 and raising it into a bridge by drawing. 5B is formed by cutting and raising the mounting base 50 to form a tongue piece. In the illustrated example, the rotation preventing portion 54b is cut and raised obliquely, but may be cut and raised substantially perpendicular to the mounting base 50. 5 (c) is obtained by bending the upper and lower sides of the mounting base 50 into a projecting shape having a semicircular cross section.
[0034]
When the bolt is inserted into the bolt locking hole 51, the side portions of the bolt head come into contact with the detent portions 54a, 54b, 54c, and the bolts co-rotate at the time of screwing and fastening the nut. Works to prevent. In the illustrated example, an example is shown in which a pair of upper and lower portions are formed, but it is also possible to provide only one of them or to provide three or more. The shape is not limited to the illustrated example, and other shapes can be adopted.
[0035]
By the fastening operation as described above, the pipe support band A holds the pipe P, and the front mounting pieces 11, 11 are fastened and fixed to the foot member 2 so as to sandwich the foot body 21. In the fastening state by the bolt 3 and the nut 4, the short cylindrical portion 53 is interposed between the mounting base 50 and the mounting piece portion 11 in a state of being pressed, so that the short cylindrical portion 53 as the raised protrusion is provided. By virtue of the restoring reaction force, a function such as a disc spring or a spring washer is developed, and the tightly superposed state of the mounting pieces 11, 11 and the foot body 21 is maintained. In order to further promote the functions of the disc spring and the like, it is also desirable to form a raised protrusion on the side surface of the mounting base 50 provided with the mounting piece 11.
[0036]
In FIG. 1, portions 55 and 55 indicated by two-dot chain lines indicate break promoting portions formed to break and remove the upper and lower pieces 52 and 52 after fastening by the bolt 3 and the nut 4. The temporary fixing device 5 according to the present invention is used for temporarily fixing these members when the attachment pieces 11, 11 are superposed and fixed to the foot member 2 by the bolts 3 and the nuts 4 as described above. Thus, it is originally unnecessary after the polymerization is fixed. In addition, because of its structure, the upper and lower pieces 52, 52 in particular are protruded, so that a hand or the like may be caught on this and the injury may occur, and the temporary fixing tool 5 is conspicuous and the appearance is not good. Furthermore, rainwater tends to accumulate, causing rust and promoting deterioration.
[0037]
The break promoting portions 55, 55 are formed to wipe out such difficulties as much as possible, and FIGS. 6A to 6H show various forms of formation. The break promoting portion 55a of FIG. 6A is formed over the entire width in the width direction by a small concave groove that linearly reduces the thickness of the mounting base 50, and the break promoting portion 55a of FIG. The portion 55b is formed by forming the small concave groove except for the center in the width direction of the mounting base 50.
[0038]
The break promoting portion 55c in FIG. 6C is a combination of the small groove and the cut from both sides of the mounting base 50. The break promoting portion 55d in FIG. The combination of the concave groove and the perforation, and the break promoting portion 55e in FIG. 6E is only formed by cutting from both sides of the mounting base 50. Further, the break promoting portion 55f in FIG. 6 (f) uses a combination of cutting and perforation, the break promoting portion 55g in FIG. 6 (g) is formed by an elliptical or oval long hole, and FIG. The break accelerating portion 55h of h) shows notches formed by a large number of small perforations.
[0039]
The break promoting portions 55a to 55h reduce the thickness of the mounting base 50 or substantially reduce the width of the mounting base 50. As described above, the mounting pieces 11, 11 are connected to the bolts 3 and If the upper and lower pieces 52, 52 are bent and bent after being superposed and fixed to the foot member 2 by the nut 4, the pieces 52, 52 are broken and removed from the break promoting parts 55a to 55h. Therefore, in the above-mentioned superposed and fixed state, since the temporary fixing device 5 has only the mounting base 50 remaining and the protruding portion is removed, there is no fear of catching a hand or the like as described above, and the appearance becomes simple, Furthermore, the pool of rainwater is reduced, and the generation of rust and the promotion of deterioration are also reduced.
[0040]
In FIG. 1, bend promoting portions 56, 56 indicated by two-dot chain lines are further formed on the front sides of the upper and lower pieces 52, 52. The bending-promoting portions 56, 56 are used to connect the leading-end protruding portions of the upper and lower pieces 52, 52 to the other mounting pieces 11, even if the pieces 52, 52 are not broken and removed by the above-mentioned breaking promoting parts 55 a to 55 h. It is intended to bend and bend on the outer side by hand or hammer.
[0041]
As the bending accelerating portions 56, 56, a formation mode similar to that of the fracture accelerating portions 55a to 55h shown in FIG. 6 can be adopted. After the respective members are polymerized and fixed in the same manner as described above, the front sides of the pieces 52, 52 are beaten to be bent from the bending promoting parts 56, 56 and spread on the outer surface of the other mounting piece 11. As in the above case, there is no protruding portion, and there is no fear of catching a hand or the like, and the appearance is simplified.
Further, in FIGS. 1 to 3, a guide for facilitating the introduction of the other mounting piece 11 in the pipe support band A is formed by bending the front ends of the pair of upper and lower pieces 52, 52 so as to open each other. Parts 57 and 57. The provision of the guide portions 57 facilitates the work of introducing the mounting piece portion 11 and temporarily fixing it by locking it to the locking claws 52a, 52a, thereby streamlining the work.
[0042]
Further, when the pieces 52, 52 are to be broken and removed from the break promoting parts 55, 55, or when the tips of the pieces 52, 52 are bent from the bend promoting parts 56, 56, the outer surface of the other mounting piece 11 is formed. At the time of deployment, the guide portions 57 serve as grip portions, so that the guide portions 57 and 57 are easy to pick and hit, and the workability of break removal, bending and exhibition work, etc., becomes very good.
[0043]
In the temporary fixing device 5 having such a configuration, a plurality of raised protrusions 58 are formed in the vicinity of the bolt insertion holes 51 on the mounting piece 11 side of the mounting base 50, as shown in FIG. Are screwed and fastened with the bolts 3 and the nuts 4, the raised protrusions 58 are interposed between the mounting base 50 and the mounting piece 11, and are pressed by both. Accordingly, a function of preventing the bolt from being loosened, such as a disc spring or a spring washer, is developed, and the above-mentioned tightly fixed state is maintained for a long time.
FIG. 7 is a perspective view showing a modified example of the temporary fixing tool 5 according to the first embodiment. 52, 52 are extended. The interval between the ridge portions 54d having a semicircular cross section is set to be substantially equal to or slightly larger than the distance between the opposing sides of the hexagonal bolt head. Therefore, as described above, when the bolt is inserted into the bolt locking holes 51, the mounting piece 11 is overlapped with the foot member and screwed and fastened with a nut, the head of the bolt becomes the ridge portion 54d, Since it fits between the 54d, the rotation of the bolt is thereby restricted, and the function of preventing the rotation of the bolt is achieved.

The bolt locking notch 51'c in FIG. 12C has a bolt projection notch 51'a in FIG. The lateral movement of the bolt locked to the portion is restricted. The bolt locking notches 51'd, 51'e, and 51'f in FIGS. 12 (d), (e) and (f) are formed by forming a notch in the centrifugal direction at the innermost locking portion. When such a notch is formed, even if the locking position of the bolt shaft portion with respect to the valley portion is slightly ahead of the shaft portion, the locking position moves to the head side when tightening with the nut. And a decrease in the fastening strength can be prevented.
[0058]
FIG. 13 shows another example of the bolt locking means formed in the mounting base 50. The bolt inserting hole 51A and the bolt inserting hole 51A are connected to the through holes of the mounting piece in the attached state. It comprises a bolt locking slot 51B extending to a corresponding position. The diameter d2 of the bolt insertion hole 51A is larger than the peak diameter of the bolt shaft portion, and the width dimension d of the long hole portion 51B is slightly smaller than the peak diameter of the bolt shaft portion and slightly larger than the valley diameter similarly to the above. ing. Therefore, when the shaft of the bolt is inserted into the bolt insertion hole 51A and then moved laterally (leftward in the figure) along the elongated hole portion 51B, the opening edge of the elongated hole portion 51B becomes a valley of the bolt shaft portion. Then, the bolt is fitted into the long hole portion 51B in a state where the bolt is prevented from coming off in the axial direction.
[0059]

【The invention's effect】
According to the first to fourth aspects of the present invention, when the locking claw of the temporary fixing device is introduced into the mounting piece of the pipe support band and temporarily fixed, each of the upper and lower ends of the mounting piece is attached to the mounting piece. Since the guide is guided by the section guide, the locking claw can be easily introduced into the mounting piece. Therefore, the workability is good and the work can be rationalized, and it can also contribute to safety in work at a high place.
[0068]
In particular, according to the invention of claim 3, the bolt locking space is formed by the bolt locking notch which is cut out from the side of the mounting base and extends to a position corresponding to the through hole in an attached state. When the bolt is locked in the bolt locking notch in the pipe arranging work, the shaft of the bolt is moved laterally from the notch opening of the bolt locking notch and locked. Also, no impact is applied to the thread of the bolt, and the thread is not worn. In addition, since the notch edge of the notch fits into the valley of the bolt shaft, the axial movement of the bolt is prevented by this restriction, and the bolt does not come off.
[0069]
Further, according to the invention of claim 4, the bolt locking space is a bolt insertion hole formed in the mounting base, and extends to a position corresponding to the through hole in the attached state in a state of being connected to the bolt insertion hole. Since it is formed by the long hole for bolt locking, the opening edge of the long hole portion fits into the valley of the bolt shaft portion, and stress such as wear of the screw thread of the bolt is not applied. This restriction prevents the bolt from moving in the axial direction and prevents the bolt from coming off.
[0070]
According to the invention of claim 5, in the temporary fixing device for the pipe supporting band, the upper and lower ends of the mounting piece guided by the mounting piece guide eventually slide on the surface of the locking claw, and the back side thereof. Get stuck in. Therefore, by a simple operation of moving the upper and lower ends of the mounting piece along the mounting piece guide, the locking claw can be introduced into the mounting piece and temporarily fixed.
[0071]
According to the sixth aspect of the present invention, since the second locking claw for gripping the one mounting piece with the mounting base is further provided on the piece, the mounting base is connected to the one mounting piece. When attached to the mounting member, the second locking claw is locked to one of the mounting pieces, and the mounting base can be prevented from falling off from the one of the mounting pieces.
[0072]
According to the seventh aspect of the invention, since the detent portion of the bolt head is formed outside the bolt insertion hole, the rotation of the bolt head is restricted by the detent portion when tightening the nut. By simply rotating the nut, the pair of mounting pieces sandwiching the foot member can be easily and quickly tightened, and the working efficiency can be further improved.
[0073]
According to the invention of claim 8, since the raised protrusion is formed on the mounting piece portion or the foot member mounting surface side of the mounting base, when the bolt and the nut are tightened, the raised protrusion is in contact with the mounting base. It is present between the mounting pieces or between the mounting base and the foot member, and a compressive force acts on the raised protrusion by the tightening force at the time of fastening. Therefore, the reaction force acts as a disc spring or a spring washer, and suppresses the bolt from loosening.
