Description

【０００１】
【発明の属する技術分野】
本発明は、例えば天井に吊り下げられた吊りボルト等のバー材に形鋼、ケーブル等を支持させるために、当該吊りボルトに取着されるバー材への取着体に関するものである。
【０００２】
【従来の技術】
従来より、天井から吊り下げられたバー材としての吊りボルトに管材等の長尺物を支持させるため、当該吊りボルトには支持具が取り付けられている。前記吊りボルトがその一端が天井に固定され、他端に形鋼等が取り付けられている場合、支持具としては吊りボルトの他端部側から螺合することなく、吊りボルトの径方向、即ち側方から取り付けることができるタイプのものが使用される。このようなタイプの支持具としては、例えば実開平７−１９６８８号公報に開示される長尺物支持具が知られている。
【０００３】
前記長尺物支持具は、湾曲した金属製の帯板によって形成されている。その帯板の一端部には吊りボルトに帯板を取着するための取着部が形成されている。その取着部には、切り欠きが形成され、その切り欠きを形成する一対の係止突片の相対向する位置には、それぞれ吊りボルトの外周面に係合可能な係合爪が形成されている。また、帯板の他端部には、帯板の他端側を湾曲させた状態で、帯板の一端部に係止させるための係止部が形成されている。
【０００４】
そして、吊りボルトが切り欠き内へ挿入されるように、帯板を吊りボルトの側方から押し込み、両係合爪を吊りボルトの外周面に係合させることにより、長尺物支持具が吊りボルトに側方から取り付けられる。次に、帯板の両端部間に形成された開口から帯板内へ長尺物を収容し、係止部を帯板の一端部に係止させると、取着部によって吊りボルトに取着された長尺物支持具により、長尺物が吊りボルトに支持される。
【０００５】
【発明が解決しようとする課題】
ところが、上記従来の長尺物支持具により長尺物が吊りボルトに支持された状態では、吊りボルトに係合している部位である係合爪には、長尺物支持具及び長尺物の荷重が加わっている。このとき、取着部には切り欠きが形成され、係合爪が形成された一対の係止突片の先端部同士の間は連結されず自由端となっている。そのため、長尺物支持具に重量の大きい長尺物が支持され、係合爪に大きな荷重が加わると、同係合爪ひいては取着部が変形する虞があり、長尺物支持具を吊りボルトに強固に取着することができないという問題があった。
【０００６】
本発明は、上記従来技術に存在する問題点に着目してなされたものである。その目的とするところは、バー材の径方向から取着することができ、そのバー材に対して強固に取り付けることができるバー材への取着体を提供することにある。
【０００７】

【００１６】
【発明の実施の形態】
以下、本発明を具体化したバー材への取着体の一実施形態を図１〜図５に従って説明する。
【００１７】
図１に示すように、バー材への取着体１０（以下、単に取着体１０と記載する）は、前記バー材としてのボルトである吊りボルト１１に支持体としての形鋼１２を支持させるために前記吊りボルト１１の長さ方向における適宜位置に、同吊りボルト１１の径方向から取着されるものである。なお、前記径方向とは、図１において、上下方向に延びる吊りボルト１１の直径の延びる方向とする。図２に示すように、取着体１０は、内側挟持体１３及び外側挟持体１４と、引寄手段としてのボルト１５ａ及びナット１５ｂとより形成されている。
【００１８】
まず、前記吊りボルト１１について説明すると、図１に示すように、吊りボルト１１は、金属棒により長尺状に形成され、図示しない天井から吊り下げられることにより上下方向へ延び、外周面にネジ山１１ａが螺刻されているものである。次に、支持体としての形鋼１２は金属材料により断面Ｌ字状をなす長尺状に形成されている。また、形鋼１２には前記ボルト１５ａが挿通可能な取付孔（図示せず）が複数箇所に形成されている。
【００１９】
次に、前記取着体１０について具体的に説明する。図２に示すように、金属材料製の前記内側挟持体１３は、側面に開口を有する略細長四角箱状に形成されている。内側挟持体１３は略コ字状に切り欠き形成された上下一対の周壁としての側壁１６と、それら上下両側壁１６の一方（図２では右方）の短辺側の縁部同士を連結する周壁としての連結壁１７とにより形成されている。
【００２０】
前記上下両側壁１６には、それぞれ内側挟持体１３の長辺側に開口する挿入部としての内側挿入部１８ａが上下に相対向するように形成されている。そして、前記各内側挿入部１８ａにより内側挟持体１３の長辺側から当該内側挟持体１３の内部に前記吊りボルト１１を挿入することができる。さらに、上下両側壁１６には、前記各内側挿入部１８ａに連通する凹部としての内側収容凹部１８ｂが上下に相対向するように形成されている。前記各内側収容凹部１８ｂが内側挟持体１３の長辺に沿って延びる方向と、各内側挿入部１８ａが内側挟持体１３の長辺側から同内側挟持体１３の内部に向かって延びる方向とは略直交している。
【００２１】
そして、前記各内側挿入部１８ａにより、吊りボルト１１を内側挟持体１３の長辺側から同内側挟持体１３内に挿入することができ、さらに、各内側収容凹部１８ｂ内へ収容することができるように形成されている。図５に示すように、各内側収容凹部１８ｂ内への吊りボルト１１の収容状態では、吊りボルト１１は径方向の長さにおけるほぼ全体が内側収容凹部１８ｂ内に収容される。
【００２２】
前記各内側収容凹部１８ｂ内の奥部の内周縁には、それぞれ平面視Ｖ字状をなす挟持部１８ｃが形成されている。即ち、内側挟持体１３には挟持部１８ｃが上下二段に形成されている。また、前記上下両側壁１６の外面には、それぞれ前記各挟持部１８ｃに沿って延びる補強挟持片１９が補強手段として突設されている。
【００２３】
そして、前記各挟持部１８ｃ及び各補強挟持片１９と外側挟持体１４とにより吊りボルト１１を挟持するようになっている。さらに、図４に示すように、連結壁１７には貫通孔１７ａが形成され、その貫通孔１７ａに前記ボルト１５ａの一端部が螺着又は溶接され、当該ボルト１５ａの他端側が内側挟持体１３の外方へ突出している。
【００２４】
図２に示すように、金属材料製の前記外側挟持体１４は、側面に開口を有する略細長四角箱状に形成され、前記内側挟持体１３より若干大きく形成されている。外側挟持体１４は平面視略横コ字状に切り欠き形成された周壁としての上下両側壁２０と、それら上下両側壁２０の一方（図２では右方）の短辺側の縁部同士を連結する周壁としての連結壁２１とにより形成されている。
【００２５】
上下両側壁２０には、それぞれ外側挟持体１４の他方（図２では左方）の短辺側から外側挟持体１４の内部に吊りボルト１１を収容するために開口する凹部としての外側収容凹部２２が上下に相対向するように形成されている。前記各外側収容凹部２２は外側挟持体１４の長辺方向に沿って直線状に延びるように形成されている。図５に示すように、各外側収容凹部２２内への吊りボルト１１の収容状態では、吊りボルト１１は径方向の長さにおける全体が各外側収容凹部２２内に収容される。また、図２に示すように、上側壁２０の長辺方向に沿った両側縁部はそれぞれ下方へ折り曲げられ、下側壁２０の長辺方向に沿った両側縁部はそれぞれ上方へ折り曲げられている。
【００２６】
前記各外側収容凹部２２内の奥部の内周縁には、それぞれ平面視横Ｖ字状をなす挟持部２２ａが形成されている。即ち、外側挟持体１４には挟持部２２ａが上下二段に形成されている。それら挟持部２２ａは、同挟持部２２ａが吊りボルト１１のネジ山１１ａ間に入り込み可能とすべく厚みが外側挟持体１４のその他の部位より薄く形成されている。そして、図５に示すように、内側挟持体１３の挟持部１８ｃ及び補強挟持片１９と外側挟持体１４の挟持部２２ａとにより吊りボルト１１の外周面を挟持するようになっている。
【００２７】
図４に示すように、前記連結壁２１には透孔２３が形成され、その透孔２３に前記ボルト１５ａが挿通されるように形成されている。図３に示すように、透孔２３にボルト１５ａを挿通し、そのボルト１５ａに前記ナット１５ｂを螺合することにより、内側挟持体１３と外側挟持体１４とが一体的に組付けられる。なお、前記ボルト１５ａは、取着体１０に前記形鋼１２を取り付けるための取付部として形成されている。
【００２８】
そして、図４に示すように、ナット１５ｂがボルト１５ａに螺着されることにより、内側挟持体１３と外側挟持体１４とが相対的に引寄せられるようになっている。一方、ナット１５ｂをボルト１５ａから螺退させ、内側挟持体１３を外側挟持体１４内から引き出し、両者を離間させることにより、内側挟持体１３と外側挟持体１４とを分離させることができる。内側及び外側挟持体１３，１４を相対的に引寄せる際又は離間させる際に、内側及び外側挟持体１３，１４の引寄方向又は離間方向は前記内側収容凹部１８ｂ及び外側収容凹部２２が延びる方向と同一となっている。
【００２９】
また、ボルト１５ａにナット１５ｂが螺着された状態で、内側挟持体１３は、外側挟持体１４の開口から同外側挟持体１４内に収容、配置される。その収容状態では、内側挟持体１３の外側に外側挟持体１４が装着されるように形成されている。
【００３０】
次に、上記構成の取着体１０の作用を使用方法とともに記載する。
さて、取着体１０を使用し、吊りボルト１１に形鋼１２を支持させるには、まず、図３に示すように、ボルト１５ａからナット１５ｂを螺退させ、内側挟持体１３と外側挟持体１４とを離間させるとともに、内側挿入部１８ａの開口を開放する。このとき、内側及び外側挟持体１３，１４の離間方向は、内側挿入部１８ａが延びる方向と直交している。そのため、内側挿入部１８ａが前記離間方向と同じ方向に延びて形成されている場合と比較して、内側挿入部１８ａを開口させるために両者を離間させる距離が短くなる。
【００３１】
続けて、吊りボルト１１が各内側挿入部１８ａ内へ挿入されるように吊りボルト１１を押し込み、さらに、取着体１０を移動させて内側収容凹部１８ｂ内に吊りボルト１１を収容させる。すると、吊りボルト１１の径方向から内側及び外側挟持体１３，１４が当該吊りボルト１１に装着され、その装着状態で内側及び外側挟持体１３，１４は吊りボルト１１を挟んだ相対向する位置に配置される。
【００３２】
次いで、図４に示すように、ボルト１５ａが形鋼１２の取付孔に挿通されるように取着体１０を形鋼１２に取り付け、その後、ボルト１５ａにナット１５ｂを螺合する。ナット１５ｂのボルト１５ａに対する螺進により形鋼１２が取着体１０側へ押され、その形鋼１２により外側挟持体１４が内側挟持体１３に近づく方向へ押されて内側挟持体１３に外側挟持体１４が引き寄せられる。
【００３３】
すると、内側挟持体１３が外側挟持体１４内に収容されていき、内側収容凹部１８ｂと外側収容凹部２２とが互いの延びる方向に沿って重なり、挟持部１８ｃと挟持部２２ａとが互いに近づく。そして、図５に示すように、平面視において、外側収容凹部２２の内側に各内側収容凹部１８ｂが収容されていき、図４及び図５に示すように、内側挟持体１３の外側に外側挟持体１４が装着される。また、内側挟持体１３の各側壁１６における各内側挿入部１８ａの開口は、それぞれ上下両側壁２０により閉鎖され、各内側挿入部１８ａ内から吊りボルト１１が抜け出る不具合が防止される。
【００３４】
図４に示すように、内側挟持体１３に外側挟持体１４が装着された状態では、上下二段の挟持部１８ｃ及び補強挟持片１９と、上下二段の挟持部２２ａとにより、吊りボルト１１の長さ方向に沿って間隔をおいた二箇所の外周面が挟持される。このとき、内側収容凹部１８ｂ内には吊りボルト１１の径方向における長さのほぼ全体が収容され、外側収容凹部２２内には、吊りボルト１１の径方向における長さ全体が収容されている。
【００３５】
また、補強挟持片１９の内周面と、挟持部２２ａの内周面とがほぼ同じ高さに相対向するように位置しているため、吊りボルト１１の外面の相対向する位置が挟持される。加えて、図５に示すように、挟持部２２ａの先端がネジ山１１ａ間に入り込むため、その挟持部２２ａがネジ山１１ａ外面に係合して、吊りボルト１１の延びる方向に沿った取着体１０の移動が防止される。
【００３６】
その結果、図１に示すように、吊りボルト１１の長さ方向における適宜位置に取着体１０が取着され、その取着体１０により、吊りボルト１１に形鋼１２が支持される。ボルト１５ａの外面には挟持部１８ｃ，２２ａが係合し、その挟持部１８ｃ，２２ａの近傍位置には、取着体１０及び形鋼１２の荷重が加わっている。
【００３７】
このとき、取着体１０において側壁１６，２０同士が重なり、連結壁１７，２１同士も重なり合ってそれぞれ厚みが厚くなり、取着体１０全体が補強されて応力に対する強度が高められている。また、補強挟持片１９により挟持部１８ｃに沿った位置が補強されている。そのため、形鋼１２の荷重によって取着体１０の長側縁部及び一方の短辺側ひいては、内側挟持体１３、さらには外側挟持体１４の変形を防止することができる。
【００３８】
上記実施形態によれば、以下のような特徴を得ることができる。
（１）内側挟持体１３が外側挟持体１４の内側に配置されることにより、取着体１０の応力に対する強度が高められているため、形鋼１２の荷重による取着体１０の変形を防止することができる。その結果、取着体１０の変形による吊りボルト１１に対する取付状態の不安定化、吊りボルト１１に沿った取着体１０の移動等の不具合をなくして、取着体１０を吊りボルト１１に強固に取り付けることができる。
【００３９】
（２）補強挟持片１９により挟持部１８ｃの近傍位置を補強することができ、外側挟持体１４との協働により内側挟持体１３等の変形を効果的に防止することができる。
【００４０】
（３）補強挟持片１９と挟持部２２ａとにより、吊りボルト１１における同じ高さの相対向する位置を挟持することができる。そのため、補強挟持片１９と挟持部２２ａとにより吊りボルト１１の外周面をほぼ同じ力で挟持することができ、取着体１０を吊りボルト１１に強固に取着することができる。
【００４１】
（４）吊りボルト１１はその径方向の長さ全体が外側収容凹部２２内に収容され、さらに、吊りボルト１１は外側収容凹部２２内で内側収容凹部１８ｂ内にほぼ全体が収容される。そのため、吊りボルト１１が内側収容凹部１８ｂ及び外側収容凹部２２内から容易に抜け出るのを防止することができ、取着体１０から抜け出る不都合を確実になくすことができる。
【００４２】
（５）挟持部１８ｃ，２２ａは、内側及び外側挟持体１３，１４の引寄方向に沿って延びる内側収容凹部１８ｂ及び外側収容凹部２２内の奥部に形成されている。そのため、引寄手段により内側及び外側挟持体１３，１４を引寄せるに連れて挟持部１８ｃ，２２ａを互いに近づけることができ、それら挟持部１８ｃ，２２ａによって吊りボルト１１の外周面を強固に挟持することができる。
【００４３】
（６）内側挿入部１８ａは内側収容凹部１８ｂに対して略直交して内側挟持体１３の側方に延びている。そのため、内側挟持体１３と外側挟持体１４とがボルト１５ａ及びナット１５ｂにより組み付けられているとき、内側挿入部１８ａから吊りボルト１１を内側収容凹部１８ｂ内に挿入することができる。従って、内側及び外側挟持体１３，１４を分解することなく、取着体１０の吊りボルト１１への取着作業を容易に行うことができる。
【００４４】
（７）内側挿入部１８ａの延びる方向と直交する位置に内側収容凹部１８ｂを形成したため、内側収容凹部１８ｂ内に収容された吊りボルト１１が内側収容凹部１８ｂから容易に抜け出るのを防止することができる。そのため、内側挟持体１３に外側挟持体１４を装着するとき、吊りボルト１１を内側収容凹部１８ｂ内に保持して外側収容凹部２２内に吊りボルト１１を収容する作業及び内側及び外側挟持体１３，１４の装着作業を容易に行うことができる。
【００４５】
（８）内側挟持体１３の長辺側に内側挿入部１８ａの開口が形成されている。そのため、内側挿入部１８ａの開口が連結壁１７側に形成されている場合と比較して、吊りボルト１１を内側収容凹部１８ｂに挿入するために内側挟持体１３と外側挟持体１４を離間させる距離を短くすることができる。従って、吊りボルト１１に取着体１０を取り付ける作業を容易に行うことができる。
【００４６】
（９）内側挟持体１３に外側挟持体１４を装着したとき、外側挟持体１４の側壁２０により、内側挿入部１８ａの開口を閉鎖することができる。従って、取着体１０から吊りボルト１１が抜け出る虞をなくすことができ、取着体１０を吊りボルト１１に確実に取着することができる。
【００４７】
（１０）挟持部１８ｃ及び補強挟持片１９と、挟持部２２ａとにより吊りボルト１１の相対向する外周面を強固に挟持することができるため、吊りボルト１１に取着体１０を強固に取り付け、形鋼１２を吊りボルト１１に確実に支持させることができる。
【００４８】
（１１）挟持部１８ｃ，２２ａの内面により吊りボルト１１の長さ方向に沿った上下二箇所が挟持されるため、取着体１０を吊りボルト１１により一層強固に取り付けることができる。
【００４９】
（１２）挟持部２２ａはネジ山１１ａの外面に係合するため、取着体１０の吊りボルト１１の長さ方向に沿った移動を防止することができ、形鋼１２の吊りボルト１１の長さ方向に沿った移動を防止することができる。
【００５０】
（１３）内側挟持体１３と外側挟持体１４との引寄せをボルト１５ａに対するナット１５ｂの螺合により行うことができ、内側及び外側挟持体１３，１４による吊りボルト１１に対する挟持を容易に行うことができるとともに、引寄手段を容易に設けることができる。
【００５１】
（１４）ボルト１５ａを外側挟持体１４の透孔２３を貫通させることにより、内側挟持体１３と外側挟持体１４とを一体的に組付けることができる。そのため、内側挟持体１３と外側挟持体１４とを分離しにくくして、取着体１０の吊りボルト１１に対する取付作業を容易に行うことができる。
【００５２】
（１５）内側挟持体１３に接合されたボルト１５ａにより取着体１０における形鋼１２の取り付け機能と、ナット１５ｂの螺合による内側挟持体１３と外側挟持体１４との引寄機能を発揮させることができる。従って、各機能を別部材を設けて発揮させる場合と比較して、取着体１０の構成を簡易化することができるとともに、製作コストを低く抑えることができる。
【００５３】
なお、上記実施形態は以下のように変更してもよい。
・　図６に示すように、吊りボルト１１に螺合されるナットとして取着体１０を使用してもよい。取着体１０をナットとして使用する場合は、例えば一対の取着体１０を使用し、それら取着体１０の間には、例えば、揺れ止め金具３０が配置されている。前記揺れ止め金具３０は金属板を折り曲げ成形して形成されている。揺れ止め金具３０の両端部には前記吊りボルト１１又は吊りボルト１１とは別体の連結ボルト（図示せず）を挿通可能とする挿通孔（図示せず）が形成されている。なお、前記連結ボルトは、一端が天井に固定され、他端が揺れ止め金具３０に固定されるものである。
【００５４】
そして、揺れ止め金具３０は、一方の挿通孔に吊りボルト１１が挿通されて一対の取着体１０の間に配置されている。次に、いずれか一方の取着体１０を吊りボルト１１に沿って回転させる。このとき、挟持部２２ａはネジ山１１ａ間に入り込んでいるため、取着体１０はネジ山１１ａに沿って螺進していき、取着体１０同士の間に揺れ止め金具３０の一端部が挟持されるとともに、揺れ止め金具３０が吊りボルト１１に固定される。
【００５５】
さらに、揺れ止め金具３０の他方の挿通孔に前記連結ボルトの他端を挿通し、さらにその他端にナット（図示せず）を螺合して連結ボルトの他端を揺れ止め金具３０に固定する。その結果、連結ボルトによって揺れ止め金具３０の揺れが防止され、その揺れ止め金具３０により吊りボルト１１に支持された部材の揺れを防止することができる。
【００５６】
・　取着体１０一体を、支持体支持用のナットとして使用してもよい。例えば、支持体としての形鋼に形成された上下方向に貫通する貫通孔内に吊りボルト１１を挿通し、次に、上記のように取着体１０を吊りボルト１１に螺着する。その結果、取着体１０により形鋼１２が支持される。このときも、取着体１０において、挟持部１８ｃ，２２ａの近傍位置には形鋼の荷重が加わるが、取着体１０の応力に対する強度が高められているため、変形が防止される。従って、取着体１０が変形等して吊りボルト１１に対する取着状態が不安定になり、取着体１０が吊りボルト１１に沿って下方へ移動する虞をなくして、形鋼を安定した状態で支持することができる。
【００５７】
・　図７に示すように、支持体としての管４０、ケーブル等の長尺物を支持する支持部材としての長尺物支持フック３２を取着体１０により吊りボルト１１に取着してもよい。前記長尺物支持フック３２は金属製の帯状をなす板材を半円状に成形して形成され、その凹んだ内部に前記管４０を支持可能に形成されている。また、長尺物支持フック３２の一端部にはボルト１５ａを挿通可能な挿通孔（図示せず）が形成されている。
【００５８】

Then, as shown in FIG. 4, the nut 15b is screwed onto the bolt 15a, so that the inner holding body 13 and the outer holding body 14 are relatively drawn. On the other hand, the inner clamp 13 and the outer clamp 14 can be separated by unscrewing the nut 15b from the bolt 15a, pulling the inner clamp 13 out of the outer clamp 14, and separating them. When the inner and outer sandwiching bodies 13 and 14 are relatively drawn or separated, the direction in which the inner and outer sandwiching bodies 13 and 14 are drawn or separated is the direction in which the inner housing recess 18b and the outer housing recess 22 extend. Is the same as
[0029]
Further, with the nut 15b screwed to the bolt 15a, the inner holding body 13 is accommodated and arranged in the outer holding body 14 through the opening of the outer holding body 14. In the housed state, the outer holding member 14 is formed so as to be mounted outside the inner holding member 13.
[0030]
Next, the operation of the attachment 10 having the above configuration will be described together with the method of use.
Now, in order to use the attachment body 10 to support the shape steel 12 on the suspension bolt 11, first, as shown in FIG. 3, the nut 15b is screwed off from the bolt 15a, and the inner holding body 13 and the outer holding body 14 and the opening of the inner insertion portion 18a is opened. At this time, the direction in which the inner and outer clamping bodies 13 and 14 are separated is orthogonal to the direction in which the inner insertion portion 18a extends. Therefore, as compared with the case where the inner insertion portion 18a is formed to extend in the same direction as the separation direction, the distance for separating the both to open the inner insertion portion 18a is shorter.
[0031]
Subsequently, the suspension bolts 11 are pushed in such that the suspension bolts 11 are inserted into the respective inner insertion portions 18a, and the attachment body 10 is further moved so that the suspension bolts 11 are accommodated in the inner accommodation recesses 18b. Then, the inner and outer holding members 13 and 14 are attached to the hanging bolt 11 from the radial direction of the hanging bolt 11, and in the mounted state, the inner and outer holding members 13 and 14 are positioned opposite to each other across the hanging bolt 11. Be placed.
[0032]
Next, as shown in FIG. 4, the attaching body 10 is attached to the shaped steel 12 so that the bolt 15a is inserted into the mounting hole of the shaped steel 12, and then a nut 15b is screwed to the bolt 15a. The shaped steel 12 is pushed toward the attachment body 10 by the screwing of the nut 15b with respect to the bolt 15a, and the outer holding body 14 is pushed by the shaped steel 12 in a direction approaching the inner holding body 13 so that the inner holding body 13 is held outside. The body 14 is pulled.
[0033]
Then, the inner holding body 13 is housed in the outer holding body 14, the inner housing recess 18b and the outer housing recess 22 overlap in the extending direction, and the holding portion 18c and the holding portion 22a approach each other. Then, as shown in FIG. 5, in plan view, each inner accommodating recess 18 b is accommodated inside the outer accommodating recess 22, and as shown in FIG. 4 and FIG. The body 14 is worn. Further, the openings of the respective inner insertion portions 18a in the respective side walls 16 of the inner holding body 13 are closed by the upper and lower side walls 20, respectively, thereby preventing the hanging bolt 11 from coming out of the inside of each inner insertion portion 18a.
[0034]
As shown in FIG. 4, in a state where the outer holding body 14 is mounted on the inner holding body 13, the suspension bolt 11 is formed by the upper and lower two-stage holding portion 18 c and the reinforcing holding piece 19 and the upper and lower two-stage holding portion 22 a. The outer peripheral surfaces at two locations spaced apart along the length direction of the body are clamped. At this time, substantially the entire length of the suspension bolt 11 in the radial direction is accommodated in the inner accommodation recess 18b, and the entire length of the suspension bolt 11 in the radial direction is accommodated in the outer accommodation recess 22.
[0035]
In addition, since the inner peripheral surface of the reinforcing holding piece 19 and the inner peripheral surface of the holding portion 22a face each other at substantially the same height, the opposing positions of the outer surface of the suspension bolt 11 are held. You. In addition, as shown in FIG. 5, since the tip of the holding portion 22a enters between the threads 11a, the holding portion 22a engages with the outer surface of the thread 11a, and is attached along the direction in which the suspension bolt 11 extends. The movement of the body 10 is prevented.
[0036]
As a result, as shown in FIG. 1, the attachment 10 is attached to an appropriate position in the length direction of the suspension bolt 11, and the suspension 12 is supported by the suspension 10 by the attachment 10. The holding portions 18c and 22a are engaged with the outer surface of the bolt 15a, and the load of the attachment body 10 and the shaped steel 12 is applied to the position near the holding portions 18c and 22a.
[0037]
At this time, the side walls 16 and 20 of the attachment body 10 overlap with each other, and the connecting walls 17 and 21 also overlap with each other and the thickness thereof increases, and the entire attachment body 10 is reinforced to increase the strength against stress. Further, the position along the holding portion 18c is reinforced by the reinforcing holding piece 19. Therefore, the deformation of the long side edge portion and one short side side of the attachment body 10, and furthermore, the inner holding body 13 and further the outer holding body 14 can be prevented by the load of the shaped steel 12.
[0038]
According to the above embodiment, the following features can be obtained.
(1) Since the inner holding body 13 is arranged inside the outer holding body 14, the strength of the attachment body 10 against stress is increased, and thus the attachment body 10 is prevented from being deformed by the load of the shaped steel 12. can do. As a result, the attachment body 10 is firmly attached to the suspension bolt 11 by eliminating the instability of the attachment state to the suspension bolt 11 due to the deformation of the attachment 10 and the movement of the attachment body 10 along the suspension bolt 11. Can be attached to
[0039]
(2) The position near the holding portion 18c can be reinforced by the reinforcing holding piece 19, and the deformation of the inner holding body 13 and the like can be effectively prevented by cooperation with the outer holding body 14.
[0040]
(3) Opposing positions at the same height in the suspension bolt 11 can be clamped by the reinforcing clamping piece 19 and the clamping portion 22a. Therefore, the outer peripheral surface of the suspension bolt 11 can be clamped by the reinforcement clamping piece 19 and the clamping portion 22a with substantially the same force, and the attachment body 10 can be firmly attached to the suspension bolt 11.
[0041]
(4) The entire length of the suspension bolt 11 in the radial direction is accommodated in the outer accommodation recess 22, and the suspension bolt 11 is substantially entirely accommodated in the inner accommodation recess 18 b within the outer accommodation recess 22. For this reason, it is possible to prevent the suspension bolt 11 from easily coming out of the inside housing recess 18 b and the outside housing recess 22, and it is possible to surely prevent the inconvenience of coming off the attachment body 10.
[0042]
(5) The holding parts 18c and 22a are formed in the inner housing recess 18b and the inner part of the outer housing recess 22 extending along the drawing direction of the inner and outer holding bodies 13 and 14, respectively.

Therefore, when the inner holding body 13 and the outer holding body 14 are assembled with the bolts 15a and the nuts 15b, the suspension bolts 11 can be inserted into the inner receiving recesses 18b from the inner insertion portions 18a. Therefore, the work of attaching the attaching body 10 to the suspension bolt 11 can be easily performed without disassembling the inner and outer holding bodies 13 and 14.
[0044]
(7) Since the inner housing recess 18b is formed at a position orthogonal to the direction in which the inner insertion portion 18a extends, it is possible to prevent the suspension bolt 11 housed in the inner housing recess 18b from easily falling out of the inner housing recess 18b. it can. Therefore, when the outer holding body 14 is mounted on the inner holding body 13, the operation of holding the suspension bolts 11 in the inner housing recesses 18 b and housing the suspension bolts 11 in the outer housing recesses 22, and the inner and outer holding bodies 13, 14 can be easily performed.
[0045]
(8) The opening of the inner insertion portion 18a is formed on the long side of the inner holding body 13. Therefore, as compared with the case where the opening of the inner insertion portion 18a is formed on the connection wall 17 side, the distance for separating the inner holding body 13 and the outer holding body 14 for inserting the suspension bolt 11 into the inner housing recess 18b. Can be shortened. Therefore, the work of attaching the attachment body 10 to the suspension bolt 11 can be easily performed.
