Description

【０００１】
【発明の属する技術分野】
本発明は、照明制御、動力制御等の配電機器を収納する自立型配電盤等の配電設備を床面に据付するためのチャンネルベースに関するものである。
【０００２】
【従来の技術】
従来から、例えば、照明制御、動力制御等の配電機器を収納する配電盤等の配電設備を床面に据付するものは、図６に示すように、自立型電設盤とも呼ばれている配電設備盤がチャンネルベースＡを介して据え付けられる。
【０００３】
このチャンネルベースＡは、例えば図７に示す、Ｌ型鋼のような板厚の厚い長尺鋼材を切断し、溶接にて組み合わせスカート部Ｂを形成したものが知られている。この場合、下方が開放しており、上記と同じＬ型鋼にて形成されたアンカー取付用の据付部Ｄが、同図（ｂ）に示すように、上記の水平片Ｃの内側端部から垂下させて内側に向け溶接されて固着されている。したがって、このチャンネルベースＡは、アンカー取付用の据付部Ｄを介して床面Ｆに固定され、配電設備盤本体１０が、上記水平片Ｃ上に載置されてその内側からボルト固定され床面に据え付けられる。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の技術においては、スカート部Ｂ及び据付部Ｄの両方が板厚の厚い材料にて形成されている。そのため、チャンネルベースＡ自体は強度的に頑丈であるものの、重量の大きいものとなりその運搬上問題があった。
【０００５】
ところで、上記のチャンネルベースＡの場合、床面Ｆに不陸があったときにその下面と床面Ｆとの間に生ずる隙間がガタツキの原因となるという問題もあり、そのときには、チャンネルベースＡ下面にスペーサを挿入させて据付を行う必要があった。したがって、配電設備の施工に多くの時間のかかることがあった。
【０００６】
本発明は、上記事由に鑑みてなしたもので、その目的とするところは、強度面での頑丈さを維持しながらより軽量化することができ、また、床面の不陸に容易に対応可能なチャンネルベースを提供することにある。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、本発明のチャンネルベースにあっては、自立型配電盤等の配電設備盤を床面に据付するためのチャンネルベースであって、配電設備盤本体の下部周縁に略沿うよう、所定厚さの鋼板材にて形成された平面視四角状のスカート部の内側四隅に、床面への据付部及び配電設備盤本体への取着部を有する、該スカート部より厚い板厚をもった鋼板材製の据付部材を固着させ、前記据付部として、床面の不陸による前記配電設備盤本体の傾きを是正するボルト部を有するアジャスト脚を螺着させた第１据付部と、同第１据付部より内側位置に設けたアンカー取付用の板状取付片である第２据付部とを設けたことを特徴としている。
【００１３】
【発明の実施の形態】
図１乃至図５は、本発明の請求項１乃至５全てに対応する一実施の形態を示し、図１は、本発明の一実施の形態のチャンネルベースを示す図で、（ａ）は平面図、（ｂ）は側面図である。図２は、同チャンネルベースの概略構成を示し、（ａ）は平面図、（ｂ）は側面図、（ｃ）は部分側面図である。図３は、同チャンネルベースの据付部材を示し、（ａ）は平面図、（ｂ）は側面図である。図４は、同チャンネルベースのアジャスト脚を示し、（ａ）は平面図、（ｂ）は側面図である。図５は、同チャンネルベースのアジャスト脚の説明図である。
【００１４】
この実施の形態のチャンネルベース１は、自立型配電盤等の配電設備盤を床面Ｆに据付するためのチャンネルベースであって、配電設備盤本体１０の下部周縁に略沿うよう、所定厚さの鋼板材にて形成されたスカート部２の内側に、床面Ｆへの据付部５及び配電設備盤本体１０への取着部６を有する、該スカート部２より厚い板厚をもった鋼板材製の据付部材４を配設させてなる。
【００１５】
又、該実施の形態のチャンネルベース１においては、前記スカート部２を平面視四角状とし、前記据付部材４をその四隅に固着させてもいる。又、該実施の形態のチャンネルベース１においては、前記据付部５として、床面の不陸による前記配電設備盤本体１０の傾きを是正するボルト部９を有するアジャスト脚８を螺着させた第１据付部５１と、同第１据付部５１より内側位置に設けたアンカー取付用の板状取付片である第２据付部５２とを設けてもいる。又、該実施の形態のチャンネルベース１においては、前記スカート部２の上端を内側に折曲させて前記配電設備盤本体１０の下面と当接する当接片３とし、前記据付部材４を、それに一体形成した固着片７を同当接片３の裏面に溶接し固着させてもいる。又、該実施の形態のチャンネルベース１においては、前記ボルト部９の上部にそのボルト部９を回動させる係合部９１を設け、前記当接片３を、該ボルト部９を回動させる開口部３１を設けて形成してもいる。
【００１６】
詳しくは、このチャンネルベース１は、従来の技術の項にて、図６に示して説明したような、照明制御、動力制御等の配電機器を収納する収納箱体である配電設備盤本体１０を床面Ｆに据付するときに、その床面Ｆと配電設備盤本体１０との間に介在させるもので、鋼板材料製のスカート部２及び据付部材４と、据付部材４に螺着されるアジャスト脚８とを備えている。
【００１７】
スカート部２は、この場合、１．２ｍｍの板厚をもった長尺の鋼板材の当接片３となる一側を長手方向にわたって略直角に折曲させ、次いで、その平面視にて四角状となるよう短手方向に折曲させて、該長尺材の始端及び終端をスポット溶接にて接合し形成している。そして、当接片３には、予めその隣り合うものどうしを斜めに切断させて突き合わせるようにしてあり、また、その突き合わせ部に、後述するボルト部９を回動させる開口部３１の円孔が形成されるよう半円状に切欠が形成されている。この当接片３には、据付部材４の配電設備盤本体１０への取着部６がその裏面側に固着される、スカート部２の一対向辺の所定箇所に、配電設備盤本体１０をこのチャンネルベース１へ取り付けるための取付孔３２が設けられている。
【００１８】
据付部材４は、この場合、４ｍｍ程度の板厚をもった鋼板材を折曲させ、床面への据付部５となる第１据付部５１及び第２据付部５２と、配電設備盤本体１０への取着部６とを有して形成されている。この据付部材４は、詳しくは図３に示すように、取着部６から平面視略Ｌ字状となるよう、第１据付部５１及び第２据付部５２が所定の段差をもつように垂下させ、一体に形成されており、その第１据付部５１には後述するアジャスト脚８を螺着させる角ナットが溶接してあり、その第２据付部５２には後述するアンカー取付用の取付孔が穿設されている。図２にに示すように、前記スカート部２の四角状の四隅に分散させて固着されるため、板厚を厚くしても部材自体が小さいためチャンネルベース１全体の重量を増加させることが無い。
【００１９】
この据付部材４は、上記取着部６及び、第１据付部５１から延出させて上方へ屈曲されている固着片７を、上記スカート部２の当接片３の裏面に固着させる固着片としてあり、同固着片をスポット溶接し固着させるので、据付状態にてその溶接箇所が外部から隠されることとなり、チャンネルベース１の美観を高めている。また、このものの取着部６には、第１据付部５１と同じように角ナットが溶接してあり、配電設備盤本体１０へのチャンネルベース１の取着する際のトルク強度をより高くすることを可能としている。なお、この発明においては、据付部材４は、上記によるものの他、例えば短手方向の２つを一体化させても良い。
【００２０】
アジャスト脚８は、上記第１据付部５１の角ナットに螺着されるボルト部９の下部に、このボルト部９とは回転自在に係合されている座部８１が設けられて形成されている。このアジャスト脚８は、ボルト部９を第１据付部５１に対して回動させることにより座部８１が上下動自在となり、配電設備盤本体１０の傾きを床面の不陸に対応させ是正させるが、該ボルト部９の上端面にそのボルト部９を回動させる回動具であるドライバに対応する溝が係合部９１として形成されており、スカート部２の当接片３四隅の開口部３１を介してそのドライバを差し込んで容易に回動させ微調節することができる。なお、このアジャスト脚８の場合、座部８１と第１据付部５１の角ナットとの間には、座部８１の高さを適切に調節した後にそれを角ナット側に向け回動させることでボルト部９の回動を防止する、ゆるみ止めナット８２が設けられている。
【００２１】
上記のチャンネルベース１において、配電設備盤本体１０を床面Ｆに据付するときには、まず、配電設備盤本体１０の床面Ｆ上の据え付け位置にチャンネルベース１を載置させる。そして、図５に示すように、スカート部２の下面と床面Ｆとの間に隙間が生じていた場合、その平面視四角状のスカート部２の当接片３四隅の開口部３１を介して、同スカート部２の内側に固着し配設された据付部材４の、第１据付部５１のアジャスト脚８のボルト部９の係合部９１に回動具となるドライバを係合させ、上面側から回動させてアジャスト脚８の高さを適切な高さとする。このとき、アジャスト脚８のボルト部９をその上面側から容易に回動させることができるので、より短時間に是正させることができる。
【００２２】
そして、床面の不陸にてチャンネルベース１自体がガタツキが無いかどうか確認を行った後、ゆるみ止めナット８２を締め付け、第２据付部５２をアンカー取付させチャンネルベース１を床面Ｆに取付固定する。次いで、チャンネルベース１の当接片３上面に配電設備盤本体１０を載置させ、上記取付孔３２裏面側からその箱体の底板に形成されている取付孔に向けて取付ボルトを挿通させ、内側から配電設備盤本体１０をチャンネルベース１へボルト止めし据え付けさせる。
【００２３】
なお、このとき、配電設備盤本体１０の底板にもその下部周縁に略沿う平面視四角状のスカート部２の当接片３四隅の開口部３１に対応する開口を設けておくことにより、第１据付部５１のアジャスト脚８のボルト部９の係合部９１に回動具を係合させて回動させることができ、床面Ｆの不陸による配電設備盤本体１０の傾きをより是正させて据え付けすることができる。
【００２４】
したがって、以上説明したチャンネルベース１によると、自立型配電盤等の配電設備盤本体１０が、所定厚さの鋼板材にて形成された、その配電設備盤本体１０の下部周縁に略沿うチャンネルベース１のスカート部２内側に配設される、同スカート部２より厚い板厚の、床面Ｆへの据付部５及び配電設備盤本体１０への取着部６をもった鋼板材製の据付部材４を介して据え付けられるので、強度面での頑丈さを維持しながらより軽量化することができる。
【００２５】
そして、配電設備盤本体１０の下部周縁に略沿う平面視四角状のスカート部２の内側に配設される、同スカート部２の四隅に固着される、それより厚い板厚の床面Ｆへの据付部５及び配電設備盤本体１０への取着部６をもった鋼板材製の据付部材４を介して据え付けられるので、さらなる軽量化を達成できる。また、配電設備盤本体１０を、その下部周縁に略沿う平面視四角状のスカート部２の内側に配設される、同スカート部２の最も遠い箇所どうしである四隅に固着される、据付部材４のボルト部９を有するアジャスト脚８を螺着させた第１据付部５１にて床面Ｆの不陸による配電設備盤本体１０の傾きが是正されて、同第１据付部５１より内側位置に設けたアンカー取付用の板状取付片である第２据付部５２をアンカー取付させ据え付けできるので、配電設備盤本体１０の傾きをより高い精度で是正で行うことができ、しかも、スペーサを挿入させる必要も無く床面Ｆの不陸に容易に対応させ据え付けされる。
【００２６】
また、この場合、所定厚さの鋼板材にて形成された、配電設備盤本体１０の下部周縁に略沿うよう、上端を内側に折曲させてその下面と当接するスカート部２の当接片３の裏面に、それに一体形成された該スカート部２より厚い板厚の固着片７を溶接され、据付部材が固着されるので、美観良く溶接固定をすることができる。しかも、配電設備盤本体１０を、その下部周縁に略沿う平面視四角状のスカート部２の当接片３四隅の開口部３１を介して、同スカート部２の内側に固着し配設された据付部材４の、床面Ｆの不陸による前記配電設備盤本体１０の傾きを是正する第１据付部５１のアジャスト脚８のボルト部９の係合部９１に回動具を係合させて回動させ据え付けできるので、上面側から回動させて、容易に回動させることができるので、より短時間に是正させることができて使い勝手は良好である。
【００２８】
【発明の効果】
本発明のチャンネルベースによれば、配電設備盤本体の下部周縁に略沿うよう、所定厚さの鋼板材にて形成された平面視四角状のスカート部の内側四隅に、床面への据付部及び配電設備盤本体への取着部を有する、該スカート部より厚い板厚をもった鋼板材製の据付部材を固着しているので、強度面での頑丈さを維持しながらより軽量化することができる。また、据付部として、床面の不陸による前記配電設備盤本体の傾きを是正するボルト部を有するアジャスト脚を螺着させた第１据付部と、同第１据付部より内側位置に設けたアンカー取付用の板状取付片である第２据付部とを設けたので、配電設備盤本体の傾きをより高い精度で是正することができ、しかも、スペーサを挿入させる必要も無く床面の不陸に容易に対応させ据え付けされる。

A locking nut 82 for preventing rotation of the bolt portion 9 is provided.
[0021]
When installing the power distribution equipment panel body 10 on the floor F in the above-described channel base 1, first, the channel base 1 is placed at an installation position on the floor F of the power distribution equipment panel body 10. Then, as shown in FIG. 5, when a gap is formed between the lower surface of the skirt portion 2 and the floor surface F, through the openings 31 at the four corners of the contact piece 3 of the square skirt portion 2 in a plan view. Then, a driver serving as a rotating tool is engaged with the engaging portion 91 of the bolt portion 9 of the adjusting leg 8 of the first mounting portion 51 of the mounting member 4 fixedly disposed inside the skirt portion 2, By turning from the upper surface side, the height of the adjusting leg 8 is set to an appropriate height. At this time, since the bolt portion 9 of the adjusting leg 8 can be easily rotated from the upper surface side, it can be corrected in a shorter time.
[0022]
Then, after confirming whether or not the channel base 1 itself is rattled due to unevenness on the floor surface, the locking nut 82 is tightened, the second installation portion 52 is anchored, and the channel base 1 is mounted on the floor surface F. Fix it. Next, the power distribution equipment panel main body 10 is placed on the upper surface of the contact piece 3 of the channel base 1, and mounting bolts are inserted from the back surface of the mounting hole 32 toward the mounting hole formed in the bottom plate of the box body, The power distribution equipment panel body 10 is bolted to the channel base 1 from inside and installed.
[0023]
At this time, the bottom plate of the power distribution equipment panel body 10 is also provided with openings corresponding to the opening portions 31 at the four corners of the contact piece 3 of the square skirt portion 2 in a plan view substantially along the lower periphery thereof. 1 The rotating tool can be engaged with the engaging portion 91 of the bolt portion 9 of the adjusting leg 8 of the installation portion 51 to be rotated, and the inclination of the power distribution equipment panel main body 10 due to unevenness of the floor F is further corrected. And can be installed.
[0024]
Therefore, according to the channel base 1 described above, the power distribution equipment panel main body 10 such as a self-supporting power distribution board is formed of a steel plate having a predetermined thickness and is substantially along the lower peripheral edge of the power distribution equipment panel main body 10. The installation member made of a steel plate, which is disposed inside the skirt portion 2 and has a thickness 5 thicker than the skirt portion 2 and has an installation portion 5 on the floor surface F and an attachment portion 6 to the power distribution equipment panel body 10. 4, the weight can be further reduced while maintaining the strength in terms of strength.

Then, it is disposed inside the square skirt portion 2 in a plan view substantially along the lower peripheral edge of the power distribution equipment panel main body 10 and is fixed to the four corners of the skirt portion 2 to the floor surface F having a larger thickness. Can be achieved through the steel plate mounting member 4 having the mounting portion 5 and the mounting portion 6 to the power distribution equipment panel main body 10. Further, the power distribution equipment panel main body 10 is fixed to four corners of the skirt portion 2, which are disposed inside the skirt portion 2 having a rectangular shape in a plan view substantially along the lower peripheral edge thereof, which are the farthest portions of the skirt portion 2. The inclination of the power distribution equipment panel body 10 due to unevenness of the floor surface F is corrected by the first installation part 51 to which the adjusting leg 8 having the bolt part 9 of 4 is screwed, and the first installation part 51 is located inside the first installation part 51. Since the second mounting portion 52, which is a plate-like mounting piece for anchor mounting provided in the above, can be anchored and installed, the inclination of the power distribution equipment panel main body 10 can be corrected with higher accuracy and the spacer is inserted. It does not need to be installed and can be easily installed in the unevenness of the floor F.
[0026]
Further, in this case, the contact piece of the skirt portion 2 which is formed of a steel plate material having a predetermined thickness and whose upper end is bent inward so as to substantially follow the lower peripheral edge of the power distribution equipment panel main body 10 and contacts the lower surface thereof. A fixing piece 7 having a thickness greater than that of the skirt portion 2 integrally formed on the back surface of the mounting member 3 is welded to the back surface of the mounting member 3, so that the mounting member is fixed. Moreover, the power distribution equipment panel main body 10 is fixed to the inside of the skirt portion 2 via openings 31 at the four corners of the contact piece 3 of the square skirt portion 2 having a rectangular shape in plan view substantially along the lower periphery thereof. The turning tool is engaged with the engaging portion 91 of the bolt portion 9 of the adjusting leg 8 of the first installation portion 51 for correcting the inclination of the power distribution equipment panel main body 10 due to the unevenness of the floor F of the installation member 4. Since it can be rotated and installed, it can be easily rotated by being rotated from the upper surface side, so that it can be corrected in a shorter time and the usability is good.
