【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等に沿って、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、壁面等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等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係止用空所が設けられている。
【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係止用空所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、壁面等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係止用空所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、このボルト係止用空所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、ボルト・ナットの締付作業が完了するまでは極めて有効なものであるが、締付施工後は不要となり、仮止め具の利用価値はなくなってしまう。このように不要となった仮止め具を施工後も放置しておくと、見映えが悪いばかりでなく、雨水が溜まりやすく、錆の発生による劣化が促進されるという問題がある。
【０００８】
特に、片部の先端部や先端に形成された係止爪などの突出部分は、上述のように見映えが悪く、雨水の溜まり易い部分である。また、締付施工後に作業者や一般人がこの突出部分に引っ掛かるおそれもあった。
【０００９】
本発明は、上記に鑑みなされたものであり、締付施工後のパイプ支持バンド及びその周辺器具等の劣化防止や安全面をより配慮した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、上記ボルト及びナットで一対の取付片部を上記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、この取付ベースの上記添装状態で前記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、上記取付ベースの上端及び／又は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片部とよりなり、上記取付ベースには、上記取付片部と共にボルト及びナットにより足部材に固着した後、上記片部を含み破断除去し得る破断促進部を形成したことを特徴とする。
【００１１】
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空所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、壁面等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。
【００１２】
斯かる配設作業の施工後において、仮止め具は不要なものとなるにもかかわらず、取り除くことができないため、はみ出している部分が引掛かり、けがの原因になるおそれがあった。また、このはみ出している突出部分が目立ち、見映えが悪く、さらにその突出部分に水が溜まり、錆の発生原因にもなる。そこで、請求項１の破断促進部によれば、このはみ出し部分が容易に破断除去できるので、これらの問題が解決される。
【００１３】
請求項２の発明に係るパイプ支持バンドの仮止め具は、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
請求項３発明に係るパイプ支持バンドの仮止め具は、請求項１において、ボルト係止用空所は、取付ベースの側片部より切欠かれ上記添装状態で前記貫通孔に対応する位置にまで延じるボルト係止用切欠部によって形成されている。
【００１４】
請求項４発明に係るパイプ支持バンドの仮止め具は、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前記貫通孔に対応する位置にまで延じるボルト係止用長孔部によって形成されている。
請求項５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４のいずれかにおいて、上記破断促進部は、取付ベースの肉厚を線状に薄肉とする溝によって形成されていることを特徴とし、これにより道具を使うことなく素手で、片部の先側を容易に破断除去することができる。
【００１５】
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４のいずれかにおいて、上記破断促進部は、取付ベースの幅を実質的に狭める切込みによって形成されていることを特徴とし、これにより道具を使うことなく素手で、片部の先側を容易に破断除去することができる。
【００１６】
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４のいずれかにおいて、上記破断促進部は、取付ベースの幅を実質的に狭める小孔によって形成されていることを特徴とし、これにより道具を使うことなく素手で、片部の先側を容易に破断除去することができる。
【００１７】
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、上記破断促進部が、上記溝、切込み及び小孔のいずれかの組合せからなることを特徴とし、これにより道具を使うことなく素手で、片部の先側を容易に破断除去することができる。
【００１８】
請求項９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８のいずれかにおいて、上記片部は、上記取付ベースの上端及び下端から、略並行に各々延設された一対の上片部及び下片部で構成されていることを特徴とし、これにより、他方の取付片部を上下の係止爪で係止し、その仮止めを確実にできる。
【００１９】
請求項１０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９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。
【００２０】
請求項１１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１０のいずれかにおいて、上記ボルト係止用空所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。
【００２１】
請求項１２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１１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、ボルト係止用空所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。
【００２２】
【発明の実施の形態】
以下、本発明に係るパイプ支持バンドの仮止め具の実施形態を図面に基づき説明する。図１は本発明に係るパイプ支持バンドの仮止め具を用いたパイプ固定要領を示す分解斜視図、図２は本発明に係る仮止め具の第１の実施形態を示す斜視図、図３は同取付要領を示す縦断面図である。
【００２３】
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。
【００２４】
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。
【００２５】
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にその側辺部から上記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（ここでは、ボルト係止用空所が切欠き形成されたものを示す）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。
【００２６】
上記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。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。また、取付ベース５０には、ボルト係止用切欠部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・・・と、上下片部５２、５２を含んで破断除去しやすい構成とした破断促進部５５、５５とが形成されている。更に、取付ベース５０の取付片部１１側面であってボルト係止用切欠部５１、５１の周辺部に複数の隆起突部５８…が形成されている。
【００２７】
図２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。この破断促進部５５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、破断促進部５５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。
【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のボルト係止用切欠部５１にボルト３の軸部３１を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。
【００２９】
次いで、図１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。また、このような係止状態においては、ボルト３の軸部３１は取付片部１１の貫通孔１２により規制されるから、その横方向の移動も阻止される。この状態で、施工現場等に持ち込まれる。
【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がボルト係止用切欠部５１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。
【００３２】
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、上記隆起突部５８…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５８…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。
【００３３】
次いで、上述のように重合固着した後、突出する上下片部５２、５２を破断除去する。図３からもわかるようにナット４をボルト３の軸部３１に螺装締結がなされた後は上下片部５２、５２が突出している。そこで、突出した上下の片部５２、５２を反り曲げるようにすれば、破断促進部５５から片部５２、５２が破断除去される。従って、破断除去された後は、仮止め具５は、取付ベース５０のみが残る。
【００３４】
図４は、破断促進部５５の種々の形成態様を示すものである。図４（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４（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。
【００３５】
また、図４（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４（ｄ）の破断促進部５５ｄは、小凹溝と穿孔とを併用したもの、図４（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４（ｆ）の破断促進部５５ｆは、切込みと穿孔とを併用したもの、図４（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４（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。
【００３６】
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から道具使用することなく容易に片部５２、５２を破断除去することができる。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。
【００３７】
なお、ここでは上記破断促進部５５ａ〜ｈにより片部５２、５２を破断除去する構成としているが、このように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構成としてもよい。
図２では、この叩き込み折曲展装させる箇所を折曲促進部５６、５６として示している。この折曲促進部５６、５６は、図４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。
【００３８】
図５は、第１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切欠部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。
【００３９】
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た後、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。
【００４０】
更に、取付ベース５０の外面側略中央を、絞り加工により方形に凹まし、その反対面に隆起突部５８を形成している。この隆起突部５８は、上記重合状態でボルト・ナットで各部材を締結固着させた際に、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機能を発現するもので、これによりボルトの緩み防止効果が得られる。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。
【００４１】
図６に示す例は隆起突部の変形例を示すものであり、（ａ）は平面図、（ｂ）はボルトを係止させた場合の縦断面図である。即ち、ボルト係止用切欠部５１の最奥部の周辺部をボルト３の頭部３２側に隆起させ、この部分を隆起突部５８としている。従って、ナットにより締結した際、この隆起突部５８がボルト頭部３２と取付片部との間に挟圧され、その復元反力により上記同様皿ばねのような機能が発現される。
【００４２】
図７に示す例は、別の変形例であり、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。また破断促進部５５、５５から片部５２、５２を破断除去する場合、このガイド部５７、５７が把持部となるので、摘み易く破断除去作業等の施工性が大変良好となる。その他の構成は、上記と同様であるので、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。
【００４３】
図８は、更に別の変形例であり、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。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。
【００４４】
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刻印等が読み取れる状態に維持される。
【００４５】
また、取付ベース５０には、２種の実施形態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とこれに連なるボルト係止用切欠部５１と、ボルト挿入孔５９及びこれに連なるボルト係止用長孔部分５９ａとを備える。切欠部分５１ｇは、その開口幅がボルト挿入孔５９の径と略同じとされ、形状は略半円形である。
【００４６】
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の切欠部分５１ｇ及びボルト挿入孔５９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５９ａに係止させる。
【００４７】
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５９ａ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切欠部５１及びボルト係止用長孔部分５９ａ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。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。この場合も、図４と同様に、重合固着した後、突出する上下片部を破断促進部５５から破断除去し、破断除去された後は、取付ベース５０のみが残る。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（ａ）（ｂ）（ｃ）は、本発明に係る仮止め具の第２の実施形態を示すものである。図１０（ａ）（ｂ）（ｃ）は、いずれも本実施形態の仮止め具６の要部のみを示しており、その全体形状は省略されている。取付ベース６０には、取付ベース５０の側辺部より切欠かれ取付片部との添装状態でその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６１の近傍に、挿通されたボルトの頭部をその頂面から押さえる頭部押え部６０ａを、切起こし脚部６０ｂを介して設けることによりボルトの抜け出しを防止せんとするものである。
【００５０】
この場合、ボルト係止用切欠部６１に係止されるボルト３の頭部３２の頂面が頭部押え部６３により押えられ、その軸方向の抜けが阻止されるから、ボルト係止用切欠部６１の切欠開口幅は上記のように設定することを要さず、開口部からボルト軸部３１を遊挿し得るものであれば良い。図１０（ａ）（ｂ）（ｃ）のいずれの態様も望ましく採用されるものであり、特に切起こし脚部６２をボルト頭部３２の辺部に当接するようにすれば、ボルト３の廻り止め機能が付加され、その有用性が向上する。
【００５１】
尚、図１０は仮止め具６の要部だけを示しているが、取付ベース６０には上記と同様の片部や係止爪等が形成され、上記各実施形態と同様の機能を奏するよう構成されるものである。但し、図８及び図９に示す実施形態には、その特性上本実施形態は適用されない。また、図１０（ａ）の頭部押え部６３は、ボルト係止用切欠部５１の幅方向両側にあっても良いことは言うまでもない。
【００５２】
図１１（ａ）（ｂ）（ｃ）は、上記ボルトの廻り止め部５４の変形例を示す。
図１１（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１１（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１１（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。
【００５３】
これら廻り止め部５４ａ、５４ｂ、５４ｃは、ボルト係止用切欠部５１にボルトを係止した状態では、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。
【００５４】
なお、図１１に示すボルト頭部の廻り止め部５４ａ、５４ｂ、５４ｃは後述する第３の実施形態にも適用され得る。
【００５５】
図１２は、本発明に係る第３の実施形態を示すものである。この第３の実施形態では、ボルト３はボルト係止用孔部（ここでは、ボルト係止用空所が孔部で形成されたものを示す）５１にボルト３の軸部３１を挿通させる構成としている。
図１２の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と、上下片部５２、５２を含んで破断除去しやすい構成とした破断促進部５５とが形成されている。更に、取付ベース５０には、ボルト係止用孔部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。
【００５６】
なお、上述のとおり第１の実施形態と第３の実施形態の相違点は、第１の実施形態では、ボルト３はボルト係止用切欠部５１にボルト３の軸部３１をその切欠開口部より横移動させて係止させる構成としているのに対し、この第３の実施形態では、ボルト３はボルト係止用孔部５１及び短筒部５３にボルト３の軸部３１を圧入させ、この圧入による拘束力によりボルトの抜けを防止するよう構成している点である。したがって、その構成は第１の実施形態と同様に適用され、同様の機能を奏するよう構成されるものである。したがって、たとえば図４に示す破断促進部５５の種々の形成態様はそのまま適用される。
【００５７】
図１３は、上記ボルト係止用孔部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１３（ａ）（ｂ）において、ボルト挿通孔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。
【００５８】
図１３（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１３（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。
【００５９】
図１４から図１７には、上記第２の実施形態に基づく変形例を図示しており、以下説明する。
【００６０】
図１４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、ボルトをボルト係止用孔部５１、５１及び短筒部５３、５３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。
【００６１】
その他の構成は、上記図５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。
【００６２】
図１５に示す例は、別の変形例であり、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。その他の構成は、上記図７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。
【００６３】
図１６は、更に別の変形例であり、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。
【００６４】
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、刻印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刻印等が読み取れる状態に維持される。
【００６５】
図１７は、図１６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のボルト挿通孔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１７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。
【００６６】
この仮止め具５の取付ベース５０には図１６に示すようにボルト挿通孔５１の近傍部に複数の隆起突部５８…が形成されており、図１７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。
【００６７】
図１８及び図１９は、本発明に係る仮止め具の第２の実施形態の変形例を示すものである。図１８は、本実施形態の仮止め具６の要部のみを示しており、その全体形状は省略されている。本仮止め具６は樹脂の成形品からなり、厚みのある取付ベース５０には、ボルト３の軸部３１を遊挿し得るボルト係止用孔部６１が開設され、このボルト係止用孔部６１に連なりこれと同心的にボルト頭部の収容穴６２が凹設されている。更に、該収容穴６２の開口周縁部には求心方向の弾性片６３、６３が連成されており、この弾性片６３、６３は、ボルト３をボルト係止用孔部６１に挿通させた時には、ボルト３の頭部頂面に当接し、ボルト頭部押え部として機能するものである。
【００６８】
図１９は、本実施形態においてボルトを挿通させる要領を示す断面図である。
取付ベース６０に開設されたボルト係止用孔部６１の内径は、ボルト３の軸部３１の山径よりやや大とされ、ボルト軸部３１はボルト係止用孔部６１に抵抗なく遊挿される。また、対向する２つの弾性片６３、６３間の距離は、ボルト頭部３２の外径（六角ボルトの場合、対向辺間距離）より小とされている。従って、図１８のようにボルト軸部３１をボルト係止用孔部６１に挿通させる際、ボルト頭部３２の下面が弾性片６３、６３に当たるが、これに抗して更にボルト３を押し込むようにすれば、弾性片６３、６３が弾性変形する。そして、ボルト頭部３２の下面が収容穴６２の底にまで達した時には、弾性片６３、６３が弾性復元して、図１８に示すようにボルト頭部３２の頂面に当接するようになる。この状態では、ボルト頭部３２が弾性片６３、６３により規制されるから、ボルトの抜け出しが防止される。
【００６９】
尚、図１８においては、ボルト頭部収容穴６２の形状を円形としたが、このボルト頭部収容穴６２にボルトの廻り止め手段、例えば収容穴６２内に平行な壁部を設けること、或いは形状をボルト頭部の形状（六角形、四角形等）としてボルト頭部が嵌装し得るようにする等適宜採択される。また、図１８は仮止め具６の要部だけを示しているが、取付ベース６０には上記と同様の片部や係止爪等が形成され、上記各実施形態と同様の機能を奏するよう構成されるものである。但し、図１６及び図１７に示す実施形態には、その特性上本実施形態は適用されない。
【００７０】
尚、上記第１から第３実施形態における仮止め具５及び仮止め具３は、板金材で構成するのが望ましいが、これらを樹脂の成形品により構成することも可能である。また、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。更に第２の係止爪５２ｂは、係止構造により不要とされ場合がある。
【００７１】
【発明の効果】
請求項１〜９に記載のパイプ支持バンドの仮止め具は、片部に破断促進部を形成しているので、ボルト・ナットの締付施工後、不要となる片部の先側の突出部分を容易に破断除去することができる。その結果、固着後の片部の突出部分がなくなるので、見映えがよい。また、この突出部分に雨水が溜まることがなくなるため、パイプ支持バンドおよびその周辺器具の錆の発生を防ぐことができる。更に作業者や一般人が引っ掛けてしまう心配がなくなり、安全面に優れている。
【００７２】
また、請求項５から８に記載の発明のような破断促進部が形成されていれば、道具を使うことなく素手で、片部の先側を容易に破断除去することができる。
【００７３】
請求項９では、片部が、取付ベースの上端及び下端から、略並行に各々延設された一対の上片部及び下片部で構成されているから、他方の取付片部を上、下の係止爪で係止し、その仮止めを確実にできる。
【００７４】
請求項１０では、片部には、取付ベースとにより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。
【００７５】
請求項１１では、ボルト係止用空所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。
【００７６】
請求項１２では、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。

The temporary fixing member is made of a sheet metal material or the like, and is composed of a mounting base attached to one surface of one of the mounting pieces, and a pair of upper and lower pieces extending in parallel from the upper and lower ends thereof. You. This piece is provided with two types of locking claws for locking to one mounting piece and the other mounting piece, respectively, and the mounting base corresponds to a through hole for a bolt formed in the mounting piece. At the position, a bolt locking cavity having an opening diameter slightly smaller than the mountain diameter of the bolt shaft portion and having a cutout in the centrifugal direction is provided.
[0004]
When arranging a pipe on a wall surface of a building or the like by the band body using such a temporary fixing tool, the mounting claw on the mounting base is locked to one of the mounting pieces in advance to mount the mounting base. A bolt is attached to one surface of the mounting piece, a bolt is pressed into the bolt locking space formed in the mounting base, and is inserted through a through hole formed in the mounting piece. Next, the bolt is inserted into a through hole (elongated hole) of the foot member attached to a wall surface or the like, and the halved band body is held around the pipe. Then, while locking the other mounting piece to the other locking claw, the bolt is inserted through a through hole formed in the mounting piece, and a nut is screwed into the bolt to make the above Fastening is performed.
[0005]
In the pipe laying operation using the temporary fixing tool as described above, the opening diameter of the bolt locking space formed in the mounting base is smaller than the peak diameter of the bolt shaft. In a state where the bolt is inserted through the stop space and the through hole, the bolt is prevented from coming off, and there is no fear that the bolt will come out and fall even if the hand is released from the bolt during operation. Also, since the attachment pieces of the two band bodies are maintained in an overlapped state with the foot member sandwiched therebetween by the two types of locking claws formed on the one part, the band body is manually handed before the nut is tightened. The main body of the band does not come off even when it is released. Therefore, both hands of the worker are free, and the bolt and nut can be efficiently tightened while holding the pipe. In particular, at a construction site that involves dangerous work at high places on high-rise buildings such as condominiums, such good workability is highly evaluated in terms of safety.

According to a twelfth aspect of the present invention, there is provided a temporary fixing device for a pipe support band according to any one of the first to eleventh aspects, wherein a raised projection is formed on a mounting piece portion or a foot member mounting surface side of the mounting base. It is characterized. Such a raised protrusion is desirably formed in the peripheral portion of the bolt locking space, and when fastened with bolts and nuts, the raised protrusion is formed between the mounting base and the mounting piece or between the mounting base and the foot member. Since there is a gap between them, a compressive force acts on this protruding projection due to 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.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a temporary fixing device for a pipe support band according to the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing a procedure for fixing a pipe using a temporary fixing device of a pipe support band according to the present invention, FIG. 2 is a perspective view showing a first embodiment of a temporary fixing device according to the present invention, and FIG. It is a longitudinal cross-sectional view which shows the attachment point.
[0023]
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.
[0024]
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.
[0025]
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. A notch formed to extend from a side portion thereof to a position corresponding to the two through-holes 12 and 12 (here, a notch formed with a notch for bolt locking is formed). 51, 51, and a piece portion 52 extending in a substantially vertical direction from the upper end and the lower end of the mounting base 50, and provided with locking claws 52a, 52a at the distal end, which are locked to the other mounting piece portion 11. 52 basically.
[0026]
The notch width dimension d of the bolt locking notches 51 is set slightly smaller than the peak diameter of the bolt shaft 31 and slightly larger than the valley diameter. On the mounting base 50 side of the pieces 52, 52, second locking claws 52 b, 52 b for locking to the mounting piece 11 to which the mounting base 50 is attached are cut and raised. Further, the mounting base 50 is provided with a detent part 54 for the bolt 3 abutting on the side of the bolt head 32 at a position near the notch part 51 for bolt locking, and an upper and lower piece part 52, 52. Fracture accelerating portions 55, 55 are formed so as to be easily broken and removed. Further, a plurality of raised protrusions 58 are formed on the side surface of the mounting piece 11 of the mounting base 50 and around the notch portions 51 for bolt locking.
[0027]
In FIG. 2, portions 55 and 55 indicated by two-dot chain lines indicate break promoting portions formed to break and remove the upper and lower piece portions 52 and 52 after fastening with the bolt 3 and the nut 4. The fracture accelerating portion 55 reduces the thickness of the mounting base 50 or substantially narrows the width of the mounting base 50. As described above, the mounting pieces 11, 11 are fixed to the foot by the bolts 3 and the nuts 4. If the upper and lower pieces 52, 52 are bent and bent after being superposed and fixed to the member 2, the pieces 52, 52 are broken and removed from the break promoting portion 55. 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.
[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. 3 (a), the shaft 31 of the bolt 3 is laterally moved from the cutout opening and is locked in the bolt lock notch 51 of the temporary fastener 5. In this case, the notch width dimension d of the bolt locking notch 51 is slightly smaller than the mountain diameter of the bolt shaft 31 and slightly larger than the trough diameter. Moves so as to fit into the valleys of the bolt shaft 31, and the bolt 3 is locked at a predetermined position. This locking does not cause the bolt 3 to come off, and furthermore, no impact is applied to the thread of the bolt 3, so that the thread portion is not worn.
[0029]
Next, as shown in FIG. 1, the temporary fixing member 5 is locked to one of the mounting pieces 11 of the split band bodies 1, 1 temporarily held on the circumference 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. Further, in such a locked state, the shaft portion 31 of the bolt 3 is regulated by the through hole 12 of the mounting piece portion 11, so that the lateral movement thereof is also prevented. In this state, it is brought 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, but even in such a case, the shaft 31 of the bolt 3 is Since the swing is allowed about the support portion by the locking notch 51 as a fulcrum, the bolt shaft portion 31 can be easily guided to the through hole 12 and the 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.
[0032]
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 bolts 3 and the nuts 4, the above-mentioned raised protrusions 58 are interposed between the mounting base 50 and the mounting piece 11 in a pressed state. Due to the 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.
[0033]
Next, after the polymerizing and fixing are performed as described above, the projecting upper and lower pieces 52, 52 are broken and removed. As can be seen from FIG. 3, the upper and lower pieces 52, 52 project after the nut 4 is screwed to the shaft 31 of the bolt 3. Therefore, if the projecting upper and lower pieces 52, 52 are bent, the pieces 52, 52 are broken and removed from the break promoting portion 55. Therefore, after the break is removed, only the mounting base 50 of the temporary fixing tool 5 remains.
[0034]
FIG. 4 shows various forms of formation of the fracture accelerating portion 55. 4A is formed over the entire width in the width direction by a small concave groove that linearly thins the thickness of the mounting base 50, and the fracture accelerating portion 55a in 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.
[0035]
Further, the break promoting portion 55c of FIG. 4 (c) is a combination of the small concave groove and the cut from both sides of the mounting base 50, and the break promoting portion 55d of FIG. The combination of the concave groove and the perforation, and the break promoting portion 55e in FIG. 4E is based on only the cut from both sides of the mounting base 50. Further, the break promoting portion 55f of FIG. 4 (f) uses a combination of cutting and perforation, the break promoting portion 55g of FIG. 4 (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.
[0036]
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 can be easily broken without using a tool from these break promoting parts 55a to 55h. Can be removed. 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.
[0037]
Although the pieces 52, 52 are configured to be broken and removed by the break promoting parts 55a to 55h, the protruding portions of the upper and lower pieces 52, 52 may be replaced with the other parts even if the pieces are not broken and removed in this manner. It is good also as a structure which strikes in the outer side surface of the attachment piece part 11 with a hand, a hammer, etc., and bends and carries out.
In FIG. 2, the places where the knock-in bending and extension are to be performed are shown as bending promoting portions 56 and 56. The bending promoting portions 56, 56 can adopt the same form as the break promoting portions 55a to 55h shown in FIG. 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.
[0038]
FIG. 5 shows a modification of the first embodiment, in which the upper and lower ends of the mounting base 50 are bent into ridges having a semicircular cross section, and the pieces 52, 52 are extended vertically in parallel. . 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 through the bolt locking notches 51, 51 and the mounting piece is overlapped with the foot member and screwed and fastened with a nut, the head of the bolt is fixed to the ridges 54d, 54d. Since the bolt is inserted into the gap, the rotation of the bolt is regulated, and the bolt has a function of preventing rotation.
[0039]
The bent base portions 55i, 55i of the ridge portions 54d, 54d are fragile because stress is concentrated at the time of bending processing, and after being screwed and fastened with the nut, the pieces 52, 52 are warped. If it bends, the pieces 52, 52 can be broken and removed from the bent bases 55i, 55i. In particular, when the nut is screwed and fastened, the rotational stress of the bolt head is applied to the ridge portions 54d, 54d, and this stress is further accumulated in the bent base portions 55i, 55i, so that the fracture can be more easily removed. As described above, since the bent base portions 55i and 55i have the same function as the above-described fracture promoting portion, it is not necessary to separately form a fracture promoting portion in this example.
[0040]
Further, a substantially central portion on the outer surface side of the mounting base 50 is rectangularly recessed by drawing, and a raised protrusion 58 is formed on the opposite surface. When each member is fastened and fixed with a bolt and a nut in the above-mentioned superposed state, the raised protrusion 58 exerts a function such as a disc spring or a spring washer due to the restoring reaction force. A loosening prevention effect is obtained. Other configurations are the same as those described above, and thus the same reference numerals are given to common portions, and description thereof will be omitted.
[0041]
The example shown in FIG. 6 shows a modified example of the protruding projection. FIG. 6A is a plan view, and FIG. 6B is a longitudinal sectional view when a bolt is locked. In other words, the innermost peripheral portion of the bolt locking notch 51 is raised toward the head 32 of the bolt 3, and this portion is used as a raised projection 58. Therefore, when fastened by the nut, the raised protrusion 58 is pinched between the bolt head 32 and the mounting piece, and the restoring reaction force exerts a function like a disc spring as described above.
[0042]
The example shown in FIG. 7 is another modified example, in which the front portions of a pair of upper and lower pieces 52, 52 are bent so as to open each other, and the other mounting piece 11 in the pipe support band A is introduced. Guide portions 57 are provided for facilitating the operation. 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. Further, when the pieces 52, 52 are to be broken and removed from the break promoting parts 55, 55, the guides 57, 57 serve as gripping parts, so that they can be easily picked and workability such as break removal work is very good. Other configurations are the same as those described above, and thus, the same reference numerals are given to the common portions, and description thereof is omitted.
[0043]
FIG. 8 shows another modification, in which the mounting base 50 is a temporary fixing tool 5 of a type attached between one mounting piece 11 and the foot body 21. In each of the above examples, the mounting base 50 of the temporary fastener 5 is attached to the outer surface of the mounting piece 11, and in this case, rainwater is provided between the bending pieces 52, 52 and the mounting piece 11. It is expected that it will accumulate easily, cause rust, or accelerate deterioration. Also, the outer surface of the mounting piece portion 11 is often marked with the product number of the pipe support band A, the manufacturer's name, and the like, and if this surface is covered with the mounting base 50, it may interfere with site adjustment. Alternatively, the advertising effect of the product may be reduced.
[0044]
In this example, the second locking claws 52b, 52b are provided so as to protrude from the upper and lower ends of the mounting base 50 in a direction opposite to the extending direction of the pieces 52, 52. It is to be locked to one of the mounting pieces 11. Therefore, only the second locking claw 52b is present on the upper side of the mounting piece 11, and the space is increased, so that rainwater or the like hardly accumulates in this portion. In addition, the outer surface of the mounting piece 11 on which a mark or the like is made is not covered by the mounting base 50, and since there are many exposed portions, the engraved mark or the like is maintained in a readable state.
[0045]
Further, the mounting base 50 is formed with the bolt locking means of the two embodiments. That is, a notch portion 51g having a notch with a large opening width (greater than the diameter of the bolt shaft portion) from the right side of the mounting base 50 in the drawing, a bolt locking notch portion 51 connected thereto, a bolt insertion hole 59, and An elongated hole portion 59a for bolt locking connected thereto is provided. The notch portion 51g has an opening width substantially equal to the diameter of the bolt insertion hole 59, and has a substantially semicircular shape.
[0046]
FIG. 9 is a view showing a procedure for fixing the attachment pieces 11 and 11 to the foot member 2 by using the temporary fastener 5 shown in FIG. In this case, first, the shaft 31 of the bolt 3 is inserted through the through hole 12 of the one mounting piece 11, and then the shaft 31 of the bolt 3 is inserted into the cutout portion 51 g of the mounting base 50 and the bolt insertion hole 59. Thereafter, the temporary fastener 5 is moved laterally to lock the shaft 31 of the bolt 3 with the notch 51 for bolt locking and the long hole portion 59a for bolt locking.
[0047]
In this state, the bolts 3 are locked in the bolt locking notches 51 and the bolt locking long hole portions 59a, respectively, so that their removal in the axial direction is prevented. Thereafter, the shaft 31 of the bolt 3 is inserted into the long hole 22 and the through hole 12 of the foot body 21 and the other mounting piece 11 of the foot member 2 in the same manner as described above, and temporarily fixed as shown in FIG. The attachment pieces 11, 11 and the foot main body 21 are temporarily fixed by the tool 5. Then, the nut 4 is screwed and fastened to the shaft portion 31 of the bolt 3 to bring these members into a tightly fixed state.
[0048]
As shown in FIG. 8, a plurality of raised protrusions 58 are formed on the mounting base 50 of the temporary fixing member 5 near the bolt locking notch 51 and the bolt locking long hole portion 59a. As shown in FIG. 9, when screw-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. Due to the restoring reaction force, a function of preventing a bolt from loosening, such as a disc spring or a spring washer, is exhibited, and the above-mentioned tightly fixed state is maintained for a long time. Further, if the pieces 52, 52 are formed so that R is bent slightly with respect to the mounting base 50 as shown in the figure, stress concentrates on the bent portion 55. Can function as Also in this case, similarly to FIG. 4, the upper and lower projecting pieces are broken and removed from the break promoting portion 55 after the polymerizing and fixing, and after the break is removed, only the mounting base 50 remains. Since other configurations are the same as those in the above-described example, the same reference numerals are given to the common portions, and the description thereof is omitted.
[0049]
FIGS. 10A, 10B and 10C show a second embodiment of the temporary fastener according to the present invention. 10 (a), 10 (b) and 10 (c) show only the main part of the temporary fixing device 6 of the present embodiment, and the overall shape is omitted. In the mounting base 60, a bolt inserted in the vicinity of a bolt locking notch 61 which is cut out from a side of the mounting base 50 and extends to a position corresponding to the through hole in a state of being attached to the mounting piece. A head holding portion 60a for holding the head from its top surface is provided through the cut-and-raised leg portion 60b to prevent the bolt from coming off.
[0050]
In this case, the top surface of the head 32 of the bolt 3 locked by the bolt locking notch 61 is pressed by the head pressing portion 63 to prevent the bolt 3 from coming off in the axial direction. The notch opening width of the portion 61 does not need to be set as described above, and may be any as long as the bolt shaft portion 31 can be loosely inserted through the opening. 10 (a), 10 (b) and 10 (c) are preferably employed. In particular, if the cut-and-raised leg 62 is brought into contact with the side of the bolt head 32, the rotation of the bolt 3 A stopping function is added, and its usefulness is improved.
[0051]
Note that FIG. 10 shows only the main part of the temporary fixing tool 6, but the mounting base 60 is formed with the same piece, locking claw, and the like as described above, so that the same functions as those of the above-described embodiments are achieved. It is composed. However, this embodiment is not applied to the embodiment shown in FIGS. 8 and 9 due to its characteristics. Further, it goes without saying that the head pressing portion 63 in FIG. 10A may be provided on both sides in the width direction of the notch portion 51 for bolt locking.
[0052]
FIGS. 11A, 11B, and 11C show modified examples of the above-described bolt rotation stopper 54. FIG.
The rotation stopping portion 54a in FIG. 11A is formed by making two cuts in the mounting base 50 and bulging in a bridge shape by drawing. The rotation stopper 54b in FIG. 11B 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. 11C, the upper and lower sides of the mounting base 50 are bent into a protruding shape having a semicircular cross section.
[0053]
When the bolts are locked in the bolt locking notches 51, the side portions of the bolt heads come into contact with the detent portions 54 a, 54 b, 54 c, and the bolts co-rotate at the time of screwing and fastening the nut. It 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.
[0054]
The bolt stoppers 54a, 54b, 54c shown in FIG. 11 can be applied to a third embodiment described later.
[0055]
FIG. 12 shows a third embodiment according to the present invention. In the third embodiment, the bolt 3 is configured such that the shaft portion 31 of the bolt 3 is inserted into a bolt locking hole (here, a bolt locking cavity is formed by a hole) 51. And
At the opening edges of the bolt locking holes 51 in FIG. 12, short cylindrical portions 53, 53 whose inner diameter is slightly smaller than the mountain diameter of the bolt shaft 31 project in the bolt insertion direction.
Also, on the mounting base 50 side of the pieces 52, 52, second locking claws 52 b, 52 b locking to the mounting piece 11 to which the mounting base 50 is attached, and upper and lower pieces 52, 52 are included. A rupture accelerating portion 55 configured to be easily ruptured is formed. Furthermore, 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 locking holes 51, 51.
[0056]
As described above, the difference between the first embodiment and the third embodiment is that, in the first embodiment, the bolt 3 has the notch opening 51 for the bolt 3 provided with the shaft portion 31 of the bolt 3. In the third embodiment, the bolt 3 is pressed into the bolt locking hole 51 and the short cylindrical portion 53 with the shaft portion 31 of the bolt 3, whereas the configuration is such that the shaft 3 is further laterally moved and locked. The point is that the bolt is prevented from coming off by the restraining force due to the press-fitting. Therefore, the configuration is applied in the same manner as in the first embodiment, and is configured to perform the same function. Therefore, for example, various forms of formation of the fracture accelerating portion 55 shown in FIG. 4 are applied as they are.
[0057]
FIGS. 13A and 13B are schematic explanatory views of the bolt locking hole 51 and the short tubular portion 53, wherein FIG. 13A is a plan view, FIG. 13B is a cross-sectional view taken along line XX in FIG. ) Shows a modified example thereof. 13 (a) and 13 (b), the short cylindrical portion 53 protruding from the opening edge of the bolt insertion hole 51 is formed in a tapered shape in which the inner diameter is reduced in advance, and the minimum inner diameter d is smaller than the bolt. It is set slightly smaller than the mountain diameter. 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.
[0058]
FIG. 13C shows that the short cylindrical 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.
[0059]
FIGS. 14 to 17 show modified examples based on the second embodiment, which will be described below.
[0060]
FIG. 14 shows a modification of the second embodiment, in which the upper and lower ends of the mounting base 50 are bent into ridges having a semicircular cross section, and the pieces 52, 52 are extended vertically. .
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, when the bolt is inserted into the bolt locking holes 51, 51 and the short tubular portions 53, 53, and the mounting piece is overlapped with the foot member and screwed and fastened with a nut, the head of the bolt becomes Since it fits between 54d and 54d, the rotation of the bolt is thereby restricted, and the function of preventing the rotation of the bolt is achieved.
[0061]
Other configurations are the same as those in FIG. 5 described above, and thus common portions are denoted by the same reference numerals and description thereof will be omitted.
[0062]
The example shown in FIG. 15 is another modified example, in which the front side portions of a pair of upper and lower pieces 52, 52 are bent so as to open each other, and the other mounting piece 11 in the pipe support band A is introduced. Guide portions 57 are provided for facilitating the operation. 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. Other configurations are the same as those in FIG. 7 described above, and thus, the same reference numerals are given to the common portions, and the description thereof is omitted.
[0063]
FIG. 16 shows another modification, in which the mounting base 50 is a temporary fixing tool 5 of a type attached between one mounting piece 11 and the foot body 21. In each of the above examples, the mounting base 50 of the temporary fastener 5 is attached to the outer surface of the mounting piece 11, and in this case, rainwater is provided between the bending pieces 52, 52 and the mounting piece 11. It is expected that it will accumulate easily, cause rust, or accelerate deterioration. Also, the outer surface of the mounting piece portion 11 is often marked with the product number of the pipe support band A, the manufacturer's name, and the like, and if this surface is covered with the mounting base 50, it may interfere with site adjustment. Alternatively, the advertising effect of the product may be reduced.
[0064]
In this example, the second locking claws 52b, 52b are provided so as to protrude from the upper and lower ends of the mounting base 50 in a direction opposite to the extending direction of the pieces 52, 52. It is to be locked to one of the mounting pieces 11. Therefore, only the second locking claw 52b is present on the upper side of the mounting piece 11, and the space is increased, so that rainwater or the like hardly accumulates in this portion. Also, the outer surface of the mounting piece 11 on which the marking or the like is made is not covered with the mounting base 50, and since there are many exposed portions, the state where the marking or the like can be read is maintained.
[0065]

The function of preventing such loosening of the bolt is exhibited, and the tightly fixed state is maintained for a long time. Since other configurations are the same as those in the above-described example, the same reference numerals are given to the common portions, and the description thereof is omitted.
[0067]
FIGS. 18 and 19 show a modified example of the second embodiment of the temporary fastener according to the present invention. FIG. 18 shows only a main part of the temporary fixing device 6 of the present embodiment, and its overall shape is omitted. The temporary fixing member 6 is formed of a resin molded product, and a thick mounting base 50 is provided with a bolt locking hole 61 into which the shaft 31 of the bolt 3 can be loosely inserted. A receiving hole 62 for the bolt head is formed concentrically therewith. Further, elastic pieces 63, 63 in the centripetal direction are coupled to the peripheral edge of the opening of the accommodation hole 62. The elastic pieces 63, 63 are provided when the bolt 3 is inserted into the bolt locking hole 61. , Abuts against the top surface of the head of the bolt 3 and functions as a bolt head holding portion.
[0068]
FIG. 19 is a cross-sectional view showing a procedure for inserting a bolt in the present embodiment.
The inner diameter of the bolt locking hole 61 formed in the mounting base 60 is slightly larger than the mountain diameter of the shaft 31 of the bolt 3, and the bolt shaft 31 is loosely inserted into the bolt locking hole 61 without resistance. It is. Further, the distance between the two opposing elastic pieces 63, 63 is smaller than the outer diameter of the bolt head 32 (in the case of a hexagonal bolt, the distance between opposing sides). Therefore, when the bolt shaft portion 31 is inserted into the bolt locking hole portion 61 as shown in FIG. 18, the lower surface of the bolt head 32 abuts against the elastic pieces 63, 63. In this case, the elastic pieces 63, 63 are elastically deformed. When the lower surface of the bolt head 32 reaches the bottom of the accommodation hole 62, the elastic pieces 63, 63 are elastically restored and come into contact with the top surface of the bolt head 32 as shown in FIG. . In this state, since the bolt head 32 is regulated by the elastic pieces 63, 63, the bolt is prevented from coming off.
[0069]
In FIG. 18, the shape of the bolt head receiving hole 62 is circular. However, the bolt head receiving hole 62 is provided with means for preventing rotation of the bolt, for example, a parallel wall is provided in the receiving hole 62. The shape is appropriately selected, for example, by setting the shape of the bolt head (hexagon, square, etc.) so that the bolt head can be fitted. Also, FIG. 18 shows only the main part of the temporary fixing tool 6, but the mounting base 60 is formed with the same piece, locking claw, and the like as described above, so that the same functions as those of the above-described embodiments are achieved.

[0074]
According to the tenth aspect, the second portion is further provided with a second locking claw for gripping one of the mounting pieces with the mounting base. Therefore, when attaching the mounting base to the one of the mounting pieces, The second locking claw is locked to the one mounting piece, and the mounting base can be prevented from falling off from the one mounting piece.
[0075]
According to claim 11, since the detent portion of the bolt head is formed outside the bolt locking space, 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.
[0076]
According to the twelfth aspect, the raised protrusion is formed on the mounting piece portion or the foot member mounting surface side of the mounting base, so when the bolt and the nut are tightened, the raised protrusion is between the mounting base and the mounting piece portion or Since it is present between the mounting base and the foot member, a compressive force acts on the raised protrusion due to 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.
