Description

【０００１】
【発明の属する技術分野】
本発明は、相直交するＣ型鋼材，Ｉ型鋼材の鋼材相互を交差部位で締付け固定する鋼材組立用金具、並びに、鋼材相互の各交差部位を金具で締付け固定させて複数本の直交配列するＣ型鋼材とＩ型鋼材とから組み立てられる鋼材組立体に関するものである。
【０００２】
【従来の技術】
従来、相直交するＣ型鋼材，Ｉ型鋼材の鋼材相互を交差部位で締付け固定する鋼材組立用金具としては、Ｃ型鋼材の両フランジ部を内側より押え込む押え板部と、押え板部の前後端よりＣ型鋼材の長手方向に延びる狭幅なＵ字状の湾曲板部と、各湾曲部の先端縁より内向きに折れ曲ってＩ型鋼材の各フランジ部と係合する掛止め片部とを設けた止め金具と、各湾曲部の相対辺間にねじ込む締付けボルトとを組に備え、各湾曲部の相対辺を締付けボルトで締め込むことにより、鋼材相互の交差部位を押え板部と掛止め片部とで挟込み保持するものが提案されている（特許文献１）。
【０００３】
その鋼材組立用金具は、金属平板等の物品を複数枚積載させて搬送し或いは複数枚積み重ねてストックするスキッドやパレットを組み立てるものとして提案されている。この鋼材組立用金具によると、金具自体の少ない部品点数により、スキッドやパレットを堅牢なものに組み立てでき、また、これを使用しないときには分解もできて再組立を行えるところから好ましい。
【０００４】
但し、その鋼材組立用金具の場合、止め金具をＣ型鋼材の長手方向端部から必要個数分だけ内側に予め組み付け、Ｃ型鋼材を長手方向で相平行させて間隔を隔てて複数本並べてから、上辺部の両フランジ部を各掛止め片部の内側に嵌め合せるようＩ型鋼材をＣ型鋼材の直交方向から組み付けねばならない。また、逆に、両湾曲部の各掛止め片部を上辺部の両フランジ部に嵌め合せて止め金具をＩ型鋼材に必要個数分だけ予め組み付け、この止め金具をＣ型鋼材の長手方向端部から内側に組み付けながらＣ型鋼材を相平行させるよう並べなければならない。
【０００５】
その組立手順が要求されても、スキッドやパレットとして短いＣ型鋼材と数少ないＩ型鋼材とから組み立てるときには左程の問題とならない。一方、長いＣ型鋼材が必要とされ、数多くのＩ型鋼材が必要とされるスキッドやパレットを組み立てるとなると、これを組み立てるには手間が掛かる。

【００１５】
【発明の実施の形態】
以下、添付図面を参照して説明すると、図示実施の形態としては、図１並びに図２で示すように金属平板等の物品を複数枚積載させて搬送し或いは複数枚積み重ねてストックするに用いられるスキッド乃至はパレットを組み立てる場合が例示されている。この鋼材組立体（以下、「スキッド」という。）は、複数本のＣ型鋼材１（以下、「本体桟」という。）と、複数本のＩ型鋼材２（以下、「脚部桟」という。）と、二組対の組立用金具３とを構成部材として組み立てられている。
【００１６】
本体桟１は、側板部１ａ，１ｂの端縁を長手方向に沿って内方に折り曲げたフランジ部１ｃ，１ｄを有する通常のＣ型鋼材で形成されている。脚部桟２は、Ｉ型を呈するようＣ型鋼材を二本背合わせに溶接接合したもので形成されている。また、面一となるＣ型鋼材の側板部を上辺部２ａとし、その上辺部２ａの端縁を長手方向に沿って下方に折り曲げたフランジ部２ｂ，２ｃを備えて形成されている。この脚部桟２では、天地逆に組み付けられるよう下辺部２ｄの端縁もフランジ部２ｅ，２ｆとしてフランジ部２ｂ，２ｃと相対方向に折り曲げて形成されている。また、支持部２ｇは鋼材の二枚接合から剛直なものに形成されている。
【００１７】
組立用金具３は、図２で示すように本体桟１の両側板部１ａ，１ｂと脚部桟２の上辺板部２ａとで直交させる鋼材相互１，２を交差部位で締付け固定するものとして備え付けられている。また、この組立用金具３は本体桟１と脚部桟２との交差部位を両側から個別に締付け固定する二組が対に備え付けられている。その対の組立用金具３は、双方共通の構造を有し、各々左右逆向きに組み付けられるよう構成されている。
【００１８】
その組立用金具３は、図３で示すように本体桟１並びに脚部桟２の下側からあてがい固定される受け金具３０と、本体桟１の内部に組み付けられる押え金具３１と、受け金具３０と押え金具３１とを締付け固定する締付けボルト３２と、ボルト弛止め用のワッシャー３３とを備えて構成されている。締付けボルト３３としては、受け金具３０と押え金具３１とを軸線上に予め組み付けた状態で鋼材相互の交差部位に組み込めるよう、受け金具３０と押え金具３１との締付けに要する軸線長さよりも長いものが備え付けられている。
【００１９】
受け金具３０は、所定の平面形状に裁断した金属板材を折り曲げたもので、図４で示すように所定の長さの底板３０ａを基体に有し、中央の起立板部３００と、その起立板部３００から段下げさせた両肩部３０１，３０２とを有する第１の立ち壁３０ｂを底板３０ａの長手方向片側辺に設けると共に、第２の立ち壁３０ｃを底板３０ａの長手方向他側辺に設けて形成されている。この受け金具３０には、締付けボルト３２を挿通する通し穴３０ｆが底板３０ａの板面中央に設けられている。
【００２０】
底板３０ａは、図５で示すように主体桟１の幅方向に亘る長さを有するよう形成されている。中央の起立板部３００は、主体桟１のフランジ部１ｃ，１ｄより内側に嵌め込むことから、締付けボルト３２のねじ込みに伴う金具全体の回止め用として設けられている。肩部３０１，３０２は、主体桟１の各フランジ部１ｃ，１ｄを下側から受け止められるよう設けられている。第２の立ち壁３０ｂは、図６で示すように脚部桟２の片フランジ部２ｂ（２ｃ）を受け入れて主体桟１の両フランジ部１ｃ，１ｄと重なる脚部桟２の上辺部２ａを下側より受け止めるよう設けられている。
【００２１】
それに加えて、第３の立ち壁３０ｄ，３０ｅ（図４参照）が底板３０ａの幅方向両端辺に設けられている。この第３の立ち壁３０ｄ，３０ｅは、金具全体が主体桟１の長手方向にずれ動くのを防ぐよう、脚部桟２の片フランジ部２ｂ（２ｃ）を通す隙間Ｇ（図４参照）を第２の立ち壁３０ｂとの間に隔てて脚部桟２の片フランジ部２ｂ（２ｃ）を受け止めるものとして設けられている。
【００２２】
その構成中、脚部桟２の片フランジ部２ｂ（２ｃ）を第２の立ち壁３０ｃに係合するよう構成すれば、第３の立ち壁３０ｄ，３０ｅを設けるのを省くよう設計変更できる。但し、この場合には、組立作業上、脚部桟２の片フランジ部２ｂ（２ｃ）を受け入れるよう第２の立ち壁３０ｂを脚部桟２に組み付けるのに手間を要する。一方、上述した如く脚部桟２の片フランジ部２ｂ（２ｃ）を通す隙間Ｇを第２の立ち壁３０ｂとの間に隔てて脚部桟２の片フランジ部２ｂ（２ｃ）を受け止めるよう第３の立ち壁３０ｄ，３０ｅを設けると、第２の立ち壁３０ｂを脚部桟２と容易に組み付けられる。
【００２３】
押え金具３１は、主体桟１の幅方向に亘る片側部３１ａを受け金具３０の起立板部３００と当接させて主体桟１の両フランジ部１ｃ，１ｄを内側から押え止めるものとして備え付けられている（図６参照）。この押え金具３１は、両立上り部３１ａ，３１ｂが底板部３１ｃから起立した断面上向きコ字状を呈し、締付けボルト３２のねじ穴３１ｄを底板部３１ｃに設けて剛直なものに形成されている（図４参照）。
【００２４】
その組立用金具３によっては、所定の間隔を保って本体桟１を長手方向で相並行に並べると共に、脚部桟２を本体桟１の両側板部１ｃ，１ｄと脚部桟２の上辺部２ａとで直交させて本体桟１の上に所定の間隔毎に配列し、その鋼材相互の各交差部位を夫々締付け固定することから本体桟１と脚部桟２とをスキッドとして組み立てられる（図２参照）。金具全体としては、締付けボルト３２を受け金具３０の通し穴３１ｆに挿通すると共に、押え金具３１のねじ穴に螺合し、ワッシャー３３を含む受け金具３０，押え金具３１を仮組み付けさせて用いられる。
【００２５】
その金具からスキッドを組み立てる場合、先ず、抑え金具３１を主体３１のフランジ部１ｃ，１ｄより内側に組み付ける。次に、受け金具３０の起立板部３００を主体桟１のフランジ部１ｃ，１ｄより内側に嵌め込み、両肩部３０１，３０２を主体桟１の各フランジ部１ｃ，１ｄにあてがい配置すると共に、脚部桟２の片フランジ部２ｂ（２ｃ）を第２の立ち壁３０ｂと第３の立ち壁３０ｃ，３０ｄとの間に保った隙間Ｇに嵌め込んで第２立ち壁部３０ｂの内側に受け入れることから、金具全体を桟相互の直交部位に組み付ける。
【００２６】
次に、仮組み付けした締付けボルト３２を押え金具３１のねじ穴３１ｄにねじ込むことにより受け金具３０と押え金具３１とを締付け固定する。この締付けボルト３２のねじ込みに伴っては、受け金具３０の起立板部３００が主体桟１の両フランジ部１ｃ，１ｄで挟まれると共に、第３の立ち壁３０ｃ，３０ｄが脚部桟２の片フランジ部２ｂ，２ｃと当接し、また、押え金具３１の片立上り部３１ａが受け金具３０の起立板部３００と当接するから、金具全体が空回りしない。このため、締付けボルト３２を確実に螺着するようにできる。
【００２７】
その組立用金具では、本体桟１の両側板部１ｃ，１ｄと脚部桟２の上辺部２ａとで直行させるよう脚部桟２を本体桟１の上に配列した状態で、金具の組付け並びに締付けボルトのねじ込み作業を本体桟１と脚部桟２との交差部位に両側から個別に行い、また、本体桟１と脚部桟２とを直交させた全ての交差部位を締付け固定すればよいため、鋼材相互を組立体として容易に組み立てられる。
【００２８】
組立体のスキッドとしては、脚部桟２の各フランジ部２ｂ，２ｃが両肩部３０１，３０２で外側から受け止められ、また、脚部桟２のフランジ部２ｂ，２ｃが第２の立ち壁３０ｂの内側に受け入られていると共に、主体桟１の両フランジ部１ｃ，１ｄと重なる脚部桟２の上辺部２ａが第２の立ち壁３０ｂで受け止められ、更に、主体桟１の両フランジ部１ｃ，１ｄが押え金具３１で内側より押え止められている。このため、組立体全体として堅牢なものに組み立てられる。
【００２９】
そのスキッドを分解するときは、上述したとは逆に、締付けボルト３２を弛めて組立用金具３を本体桟１，脚部桟２から外せばよいから、この分解にても容易に行なえる。分解後は、各構成部を夫々個々にまとめられると共に、本体桟１，脚部桟２には突起物のような邪魔なものがないからコンパクトにまとめられる。
【００３０】
上述した実施の形態は、主に、スキッドを具体例に説明したが、工事現場の仮設壁や足場等を組み立てられるのにも適用できる。
【００３１】
なお、上述した明細書中で用いた用語及び表現は単に説明のために用いたものに過ぎず、本発明の内容を何ら限定するものではない。仮に、限定的な用語や表現を用いたとしても、これにより、本発明の形態と均等なものやその一部を排除する意図はない。
【００３２】
例えば、Ｉ型鋼材の「上辺部」，「下方に」折り曲げた両フランジ部、Ｃ型鋼材のフランジ部を「下側」から受けとめる肩部、Ｉ型鋼材の「上辺部」を「下側」より受けとめる第２立ち壁なる用語は、一例に係る組立体の設置向きに基づいて設定したもので、その向きが変われば用語としても変わる。このため、権利が要求されている本発明の範囲内で種々の変更が加えられる。
【００３３】
【発明の効果】
以上の如く、本発明の請求項１に係る鋼材組立用金具に依れば、Ｃ型鋼材の両側板部とＩ型鋼材の上辺部とで直交させてＩ型鋼材をＣ型鋼材の上に配列した状態で、金具自体の組付け並びに締付けボルトのねじ込みを交差部位毎に両側から個別に行えばよいため、鋼材相互を組立体として容易に組み立てられる。また、受け金具の起立板部並びに押え金具の構造から、金具全体が締付けボルトのねじ込みに伴って空回りしないことから、締付けボルトを確実に螺着できて鋼材相互を堅牢なものに組み立てられる。
【００３４】
本発明の請求項２に係る鋼材組立用金具に依れば、Ｉ型鋼材の片フランジ部を通す隙間を第２の立ち壁との間に保って該鋼材の片フランジ部を受け止める第３の立ち壁を底板の幅方向両端辺に設けた受け金具を備えることから、金具全体がＣ型鋼材の長手方向にずれ動かないよう確実に組み付けられる。
【００３５】
本発明の請求項３に係る鋼材組立用金具に依れば、Ｃ型鋼材の両フランジ部を内側から押え止める断面上向きコ字状の押え金具を備えることにより、押え金具を含む金具全体を曲げ強度の高いものに構成できる。
【００３６】
本発明の請求項４に係る鋼材組立体に依れば、Ｉ型鋼材の各フランジ部が受け金具の両肩部で外側から受け止められ、また、Ｃ型鋼材の両フランジ部と重なるＩ型鋼材の上辺部が第２の立ち壁で受け止められ、更に、Ｃ型鋼材の両フランジ部が押え金具で内側より押え止められているため、組立体全体として堅牢なものに組み立てられると共に、使用しないときには容易に分解できて各構成部をコンパクトにまとめられる。
【００３７】
本発明の請求項５に係る鋼材組立体に依れば、Ｉ型鋼材の片フランジ部を通す隙間を第２の立ち壁との間に隔てて該鋼材の片フランジ部を受け止める第３の立ち壁を底板の幅方向両端辺に設けた受け金具を組み付けることから、Ｉ型鋼材がＣ型鋼材と相対的に横ずれしないよう確実に組み立てられる。
【００３８】
本発明の請求項６に係る鋼材組立体に依れば、片方の立上り部を受け金具の起立板部を当接させてＣ型鋼材の両フランジ部を内側から押え止める断面上向きコ字状の押え金具を組み付けることから、Ｃ型鋼材の両フランジ部を剛直な押え金具で確実に押え止められる。

TECHNICAL FIELD OF THE INVENTION
The present invention provides a steel assembly metal fitting for fastening and fixing mutually orthogonal C-type steel materials and I-type steel materials at intersections, and a plurality of orthogonally arranged steel members by fastening and fixing the respective intersections with metal fittings. The present invention relates to a steel assembly assembled from a C-type steel material and an I-type steel material.
[0002]
[Prior art]
Conventionally, metal fittings for assembling steels of C-shaped steel and I-shaped steel which are orthogonal to each other at the crossing points are known as a holding plate for holding both flanges of the C-shaped steel from the inside, and a holding plate for the holding plate. A narrow U-shaped curved plate portion extending in the longitudinal direction of the C-shaped steel material from the front and rear ends, and a latching piece that is bent inward from a leading edge of each curved portion and engages with each flange portion of the I-shaped steel material. Parts, and a tightening bolt to be screwed between the relative sides of each curved portion are provided in a set, and by tightening the relative sides of each curved portion with the tightening bolts, the crossing portion between the steel materials is held down by the holding plate portion. There has been proposed a device in which the sheet is held and held between a hook and a hook piece (Patent Document 1).
[0003]
The steel assembly metal fitting has been proposed to assemble a skid or a pallet in which a plurality of articles such as a metal flat plate are stacked and conveyed or stacked and stocked. According to the metal assembly metal fitting, the skid and the pallet can be assembled into a solid one with a small number of parts of the metal fitting itself, and can be disassembled and reassembled when not used.
[0004]
However, in the case of the steel material assembling bracket, a required number of fasteners are pre-assembled inside from the longitudinal end of the C-shaped steel material, and a plurality of C-shaped steel materials are arranged in parallel in the longitudinal direction at intervals. The I-type steel material must be assembled from the direction perpendicular to the C-type steel material so that the two flange portions on the upper side are fitted inside the respective retaining pieces. Conversely, each of the latching pieces of both the curved portions is fitted to both flanges of the upper side, and a required number of fasteners are assembled in advance to the I-type steel material, and this fastener is attached to the longitudinal end of the C-type steel material. It is necessary to arrange the C-shaped steel materials so as to be parallel to each other while assembling them inside from the part.
[0005]
Even if the assembling procedure is required, there is no problem as far as the assembling of a short C-shaped steel material and a small number of I-shaped steel materials as skids and pallets. On the other hand, when assembling a skid or a pallet that requires a long C-type steel material and a large number of I-type steel materials, assembling the same takes time and effort.
