【発明の属する技術分野】
本発明は、軽量鉄骨製の建物躯体を形成するリップ付チャンネル材等横材の断面倒Ｌ字形部分に取り付けて使用される吊り金具に関するもので、例えば天井板吊設施工において天井吊りボルトを取り付けたり、あるいは電気配線作業中にループ状に巻かれた電線を一時的に吊り下げたり、あるいはまた建物躯体の内壁面に棚を取り付けるのに利用される。
【０００２】
【従来の技術】
軽量鉄骨製建物の天井板吊設施工において、例えば図３に示すように勾配屋根の下面に沿ってＣ形チャンネル材製の桁材１がその溝開口部を横向きにして配設されてＨ形鋼製の支柱２に連結され、また建物側壁３に沿って立設された支柱２相互間に、リップ付チャンネル材からなる横材４がその溝開口部を上向きにして上下複数段に配設されているような場合に、天井板５は、その端部以外は桁材１に勾配用吊り金具６で取り付けられる吊りボルト７によって吊支されが、この天井板５の端部では、吊りボルト７を桁材１に取り付けることができない。そこで、従来では、この天井板５の端部を吊支するための吊りボルト７を取り付ける金具を、上記リップ付チャンネル材製横材４の側面に溶接により、あるいはビス止めによって取り付け、この金具に吊りボルト７を取り付けて、天井板５の端部を吊支するようにしていた。尚、吊りボルト７はハンガー８を介して野縁受け９を支持し、この野縁受け９にフック（図示せず）を介して天井野縁１０を支持し、この天井野縁１０に天井板５が取り付けられる。
【０００３】
【発明が解決しようとする課題】
従来では、上記のように天井板６の端部を吊支するための吊りボルト８を、リップ付チャンネル材からなる横材５の側面に溶接又はビス止めした金具により取り付けて吊り下げるようにしているため、溶接やビス止め作業に非常な手間と時間を要し、施工能率が悪かった。
【０００４】
本発明は、上記のような場合に天井板の端部を吊支する天井吊りボルトをリップ付チャンネル材等の横材に対し簡単に取り付けて吊り下げできるようにするための吊り金具を提供することを目的とする。尚、本発明の吊りボルトは、天井板吊りボルトを吊り下げるのに使用されるだけでなく、電気配線作業中にループ状に巻かれた電線を一時的に吊り下げたり、また建物躯体の内壁面に棚を取り付けるような場合にも使用される。
【０００５】

【０００９】
【発明の実施の形態】
図１の（Ａ）は、本発明に係る吊り金具１１を示すもので、図３の軽量鉄骨製建物において建物側壁３側に開口部を上向きにして配設されたリップ付チャンネル材４の断面倒Ｌ字形部分に取り付けられた状態を示し、同図の（Ｂ）は吊り金具１１の斜視図である。この上向きリップ付チャンネル材４は、両側一対の垂直部４ｂ，４ｂと、両垂直部４ｂ，４ｂの上端から対向突出する水平部（リップ）４ａ，４ａと、両垂直部４ｂ，４ｂの下端部をつなぐ底壁部４ｃとからなり、このチャンネル材４の断面倒Ｌ字形部分、即ち片方の水平部（リップ）４ａ及びこれに連なる垂直部４ｂが吊り金具１１の断面倒Ｌ字形被取付部となる。
【００１０】
吊り金具１１は、鋼板をプレス加工して製作されるもので、図１の（Ａ）及び（Ｂ）から分かるように、前記倒Ｌ字形被取付部の水平部４ａ及び垂直部４ｂの外面に当接される水平部片１２及び垂直部片１３と、水平部片１２の先端から折り返されて前記被取付部の水平部４ａ下面に弾接されるように延びる押え部片１４と、前記垂直部片１３の下端部に連設された断面上向きコ字形の取付部１５とからなり、そして水平部片１２及び垂直部片１３にはそれぞれの内面に、金具取付時の金具転回ガイド１６，１７が形成され、また押え部片の先端側には、金具取付時における前記被取付部の水平部先端挿入ガイド１８が設けられている。
【００１１】
吊り金具１１の水平部片１２に設けられた金具転回ガイド１６は、水平部片１２の内面中央部に形成された断面円弧状の凹曲面部からなるもので、これは、吊り金具１１の転回操作時にこれと相対的に円弧移動する（つまり、円弧状の軌跡を描いて移動する）チャンネル材４の水平部４ａ先端Ｐをガイドして、吊り金具１１の転回を円滑に行わせる役割を有するものである。また、垂直部片１３に設けられた金具転回ガイド１７は、垂直部片１３の内面中央部に形成された断面円弧状の凹曲面部からなるもので、これも同様に、吊り金具１１の転回操作時にこれと相対的に円弧移動するチャンネル材４の水平部４ａと垂直部４ｂとの外隅部Ｑをガイドして、吊り金具１１の転回を円滑に行わせる役割を有する。
【００１２】
また、押え部片１４に設けられた被取付部の水平部先端挿入ガイド１８は、押え部片１４の先端側内面（上面）に形成された断面円弧状凸曲面部からなるもので、吊り金具１１の非使用時には、図１（Ａ）の仮想線図示のように、水平部先端挿入ガイド、即ち断面円弧状凸曲面部１８の頂部が水平部片１２の下面に極力接近した位置にあると共に、当該凸曲面部１８の先端Ｔが水平部片１２下面から十分離間し開口して被取付部の水平部４ａ先端Ｐを挿入し得るようになっている。また、吊り金具１１のコ字形取付部１５には底部片１５ａの中央部に吊りボルト挿入孔１９が設けられ、また外側立ち上り部片１５ｂにはボルト挿入孔２０が設けられている。
【００１３】
上記のように構成される吊り金具１１をリップ付チャンネル材４の断面倒Ｌ字形部分４ａ，４ｂに取り付けるには、先ず、図２の▲１▼に示すように、吊り金具１１の水平部片１２をチャンネル材４の水平部４ａ上に載せ付け、この吊り金具１１を図２の時計回りに転回して、チャンネル材４の水平部４ａ先端Ｐを、吊り金具１１の押え部片１４先端Ｔと水平部片１２下面との間の開口部に挿入する。この際、吊り金具１１の押え部片１４先端側上面が水平部先端挿入ガイド１８、即ち断面円弧状凸曲面部１８を形成していて、この凸曲面部１８の先端Ｔが水平部片１２下面から十分に離間して開口しているため、その開口部へのチャンネル材４の水平部４ａ先端Ｐの挿入が容易となる。
【００１４】
こうしてチャンネル材４の水平部４ａ先端Ｐを吊り金具１１の押え部片１４先端Ｔと水平部片１２下面との間の開口部に挿入した後、吊り金具１１を更に時計回りに転回させることにより、図２の▲２▼に示すように押え部片１４を下向きに弾性変形させて、チャンネル材４の水平部４ａを押え部片１４と水平部片１２との間に深く挿入し、最終的に吊り金具１１の水平部片１２と垂直部片１３とがチャンネル材４の水平部４ａと垂直部４ｂとにそれぞれ当接すると共に、吊り金具１１の押え部片１４がその弾性復元力によってチャンネル材４の水平部４ａ下面に圧接し、かくして吊り金具１１はチャンネル材４の被取付部４ａ，４ｂに図２の▲３▼に示すような状態に取り付け固定される。
【００１５】
尚、吊り金具１１をチャンネル材４に対して転回させる際には、同図の▲１▼及び▲２▼に示すように、相対的に円弧移動するチャンネル材４の水平部４ａ先端Ｐが吊り金具１１の水平部片１２側金具転回ガイド（凹曲面部）１６に添接してガイドされると共に、同様に円弧移動するチャンネル材４の水平部４ａと垂直部４ｂとの外隅部Ｑが吊り金具１１の垂直部片１３側金具転回ガイド（凹曲面部）１７に添接してガイドされるから、吊り金具１１は、チャンネル材４の水平部４ａ及び垂直部４ｂに対し引っ掛かったりすることなく円滑に転回できて、この水平部４ａ及び垂直部４ｂに容易迅速に取り付けられる。
【００１６】
上記のようにしてチャンネル材４の水平部４ａ及び垂直部４ｂに取り付けられる吊り金具１１は、吊り金具１１の水平部片１２と垂直部片１３とがチャンネル材４の水平部４ａと垂直部４ｂとにそれぞれ当接すると共に、吊り金具１１の押え部片１４がチャンネル材４の水平部４ａ下面に弾接してこの押え部片１４と水平部片１２とによりチャンネル材４の水平部４ａを挟着するから、水平部片１２と垂直部片１３と押え部片１４とによる３点支持作用、並びに水平部片１２と押え部片１４とによる挟着作用によって、吊り金具１１をチャンネル材４の水平部４ａ及び垂直部４ｂに対し強固に取り付け固定することができる。
【００１７】
図１の（Ａ）には、上記のようにしてチャンネル材４に取り付けた吊り金具１１を示しているが、この吊り金具１１には、コ字形取付部１５の底部片１５ａに設けてある吊りボルト挿入孔１９に天井吊りボルト７を挿入してナット２１，２１で固定する。また、この天井吊りボルト７にはハンガー８の上端部を挿通してナット２１，２１で固定する。図３は、この吊り金具１１に吊り下げた天井吊りボルト７によって天井板５の端部側を吊設する場合の天井板吊設施工例を示したものである。
【００１８】
図４は、同様なリップ付チャンネル材４の断面倒Ｌ字形部分に前記吊り金具１１を介して棚板２２を取り付ける場合の例を示したものである。この場合には、チャンネル材４の水平部４ａ及び垂直部４ｂに吊り金具１１を前記同様にして取り付け固定し、この吊り金具１１におけるコ字形取付部１５の外側立ち上り部片１５ｂに設けてあるボルト挿入孔２０を利用し、棚板２２の取付部片２３のボルト孔２３ａと上記外側立ち上り部片１５ｂのボルト挿入孔２０とにボルト２４を通してナット２５で固定すればよい。
【００１９】
以上説明した実施形態では、吊り金具１１の押え部片１４にチャンネル材４の水平部先端挿入ガイド１８を設けているが、この水平部先端挿入ガイド１８は省略してもよい。その場合、押え部片１４の先端部を水平部片１２の下面に接近させて、チャンネル材４に取り付けた時に押え部片１４の先端部がチャンネル材４の水平部４ａ下面に弾接できるようにし、また押え部片１４の先端とチャンネル材４の水平部４ａ下面との間に、チャンネル材４の水平部４ａ先端を挿入できる程度の開口部が形成されるようにする。
【００２０】
また、この実施形態では、吊り金具１１の取付部１５の底部片１５ａに吊りボルト挿入孔１９を設け、また外側立ち上り部片１５ｂにボルト挿入孔２０を設けているが、これらのボルト挿入孔１９，２０は、必要に応じていずれか一方のみを設けるようにしてもよいし、また両方とも設けなくてもよい。また、この吊り金具１１は、電気配線作業中にループ状に巻かれた電線を一時的に吊り下げたり、あるいは作業用のロープやワイヤー等を掛止するのにも使用できる。
【００２１】
また、この実施形態では、吊り金具１１を、開口部を上向きにした姿勢で配設されたリップ付チャンネル材４の断面倒Ｌ字形被取付部４ａ，４ｂに取り付けるようにしているが、吊り金具１１の被取付部は、リップ、即ち水平部４ａを持たない所謂Ｃ形のチャンネル材をその開口部を横向きにして配設されている場合にも適用でき、その場合には、Ｃ形チャンネル材の開口部と反対側から吊り金具１１を取り付けるようにすればよい。
【００２２】
【発明の効果】
請求項１に係る発明の吊り金具によれば、吊り金具の水平部片を断面倒Ｌ字形形被取付部の水平部に載せ付けて、その水平部先端を、吊り金具の押え部片先端と水平部片下面との間の開口部に挿入した状態で、吊り金具を被取付部に沿って転回させるだけで、簡単に取り付けを行うことができる。この吊り金具を被取付部に対して転回させる際には、相対的に円弧移動する（円弧状の軌跡を描いて移動する）被取付部の水平部先端が吊り金具の水平部片側金具転回ガイドに添接してガイドされると共に、同様に円弧移動する被取付部の水平部と垂直部との外隅部が吊り金具の垂直部片側金具転回ガイドに添接してガイドされるから、吊り金具は、被取付部の水平部及び垂直部に対し円滑に転回して、この被取付部に容易迅速に取り付けることができる。

上記のように被取付部の水平部及び垂直部に取り付けられる吊り金具は、吊り金具の水平部片と垂直部片とがチャンネル材の水平部と垂直部とにそれぞれ当接すると共に、吊り金具の押え部片がチャンネル材の水平部下面に弾接してこの押え部片と水平部片とにより被取付部の水平部を挟着するから、水平部片と垂直部片と押え部片とによる３点支持作用、並びに水平部片と押え部片とによる挟着作用によって、吊り金具を被取付部の水平部及び垂直部に対し強固に取り付け固定することができる。
【００２４】
請求項２に記載のように、押え部片の先端側に、金具取付時における被取付部の水平部先端挿入ガイドを形成した場合には、吊り金具の押え部片先端と水平部片下面との間への被取付部の水平部先端の挿入が容易となって、吊り金具を被取付部に対しワンタッチで取り付けることができる。
