Description

本発明は二種金属製線ぴ用アース金具に関する。   The present invention relates to a two-metal metal wire grounding metal fitting.

ビルディング、工場、駅舎、その他の建造物などにおいて、照明器具の支持、電線やケーブルの配線などの目的で二種金属製線ぴ（寸法が所定値を下回るもの）あるいは金属製ダクト（寸法が所定値以上のもの）と称される長尺の溝型鋼材（以下総称して二種金属製線ぴと記す）が配設される。   In buildings, factories, station buildings, and other buildings, for the purpose of supporting lighting fixtures, wiring of wires and cables, etc. A long groove-type steel material (hereinafter collectively referred to as a two-type metal wire) referred to as a “higher value” is disposed.

図６に示すように、二種金属製線ぴ１は、底板２と、底板２の幅方向の両端から垂直方向に延設された第１、第２の側板３、４と、第１、第２の側板３、４の先端から底板側へ斜め方向に延設された折曲げ縁部５、６を備えている。   As shown in FIG. 6, the two-type metal wire rod 1 includes a bottom plate 2, first and second side plates 3, 4 extending vertically from both ends of the width direction of the bottom plate 2, first, Bending edges 5 and 6 are provided extending obliquely from the tips of the second side plates 3 and 4 toward the bottom plate.

この二種金属製線ぴ１は、例えば吊り金具（図示せず）によって天井などに沿って吊下げ支持され、その端部１ａが例えばプルボックス１０の側面板１１の穴１２に接続金具によって接続される。二種金属製線ぴ１の下面側には照明器具（図示せず）などが取付けられ、プルボックス１０内から電線やケーブル（図示せず）が二種金属製線ぴ１内に配線される。   The two-type metal wire 1 is suspended and supported along a ceiling or the like by, for example, a hanging metal fitting (not shown), and its end 1a is connected to the hole 12 of the side plate 11 of the pull box 10 by a connecting metal fitting, for example. Is done. A lighting fixture (not shown) or the like is attached to the lower surface side of the two-type metal wire 1, and an electric wire or a cable (not shown) is wired from the pull box 10 into the two-type metal wire 1. .

二種金属製線ぴ１の端部１ａのプルボックス１０への接続は、図５に示すように、プルボックス１０の側面板１１の矩形の穴１２の両縁部に接続金具２０の両取付け片２１、２２をビス２３、２３で固定し、図６に示すように接続金具２０の断面コ字状の保持部２４を二種金属製線ぴ１の端部１ａの内側に挿入しているが、プルボックス１０と二種金属製線ぴ１間が機械的に接続されておらず電気的接続が不充分な場合がある。   As shown in FIG. 5, the end 1 a of the two-type metal wire rod 1 is connected to the pull box 10, as shown in FIG. 5. The pieces 21 and 22 are fixed with screws 23 and 23, and a holding portion 24 having a U-shaped cross section of the connection fitting 20 is inserted inside the end portion 1a of the two-type metal wire rod 1 as shown in FIG. However, there is a case where the pull box 10 and the two-type metal wire 1 are not mechanically connected and electrical connection is insufficient.

このようにプルボックス１０と二種金属製線ぴ１間の電気的接続が不充分な場合、両者間に電位差が生じて種々の電気的障害が生じるおそれがあるため、両者間にアースボンド線を接続する必要がある。   In this way, when the electrical connection between the pull box 10 and the two-type metal wire 1 is insufficient, there is a possibility that a potential difference may occur between the two and various electrical failures may occur. Need to be connected.

このため、従来では、図６に示すように、二種金属製線ぴ１の側板３か４（あるいは底板２）に穴をあけてビス２６を側板４の外側から内側へネジ込み、このビス２６でアースボンド線３０の端子３１を挟持してアースボンド線３０を二種金属製線ぴ１に電気的に接続していた。   For this reason, conventionally, as shown in FIG. 6, a hole is made in the side plate 3 or 4 (or bottom plate 2) of the two-type metal wire 1 and the screw 26 is screwed in from the outside to the inside of the side plate 4, 26, the terminal 31 of the earth bond wire 30 is sandwiched and the earth bond wire 30 is electrically connected to the two-type metal wire 1.

しかしながら、このような従来の二種金属製線ぴ１にビス２６で取付ける方法では、二種金属製線ぴ１の側板４からビス２６の軸部２６ａの先端が二種金属製線ぴ１の内部に突出するため、二種金属製線ぴ１内に配線された電線やケーブル（図示せず）を傷つけるおそれがあった。   However, in such a method of attaching to the conventional type 2 metal wire 1 with the screw 26, the tip of the shaft portion 26 a of the screw 26 from the side plate 4 of the type 2 metal wire 1 is the same as that of the type 2 metal wire 1. Since it protrudes inside, there is a risk of damaging an electric wire or cable (not shown) wired in the two-type metal wire rod 1.

このため、ビス２６の取付け後、ビス２６の軸部２６ａの先端に保護体（図示せず）を取付けなければならず、側板４への穴あけ作業や保護体の取付け作業などが極めて煩雑で多大な時間を要していた。   For this reason, after attaching the screw 26, a protector (not shown) must be attached to the tip of the shaft portion 26a of the screw 26, and drilling work to the side plate 4, attaching work of the protector, etc. are extremely complicated and enormous. It took a long time.

また、二種金属製線ぴ１への照明器具などの取付け、二種金属製線ぴ１内部への電線やケーブルの配線などの作業が終わった後の施工検査段階で設置工事の必要性を指摘される場合があるが、このような場合、二種金属製線ぴ１の側板４に穴あけ加工したり、ビス２６をネジ込んだりすると、二種金属製線ぴ１内部の電線やケーブルを傷つけるおそれがあるため、二種金属製線ぴ１内の配線済みの電線やケーブルを取り除き、ビス２６を取付けた後、もう一度電線やケーブルを配線しなおさなければならないため、大変な手間がかかっていた。   In addition, the necessity of installation work at the construction inspection stage after the completion of work such as attaching lighting fixtures to the type 2 metal wire 1 and wiring of cables and cables inside the type 2 metal wire 1 In such a case, if the side plate 4 of the type 2 metal wire 1 is drilled or the screw 26 is screwed in, the electric wire or cable inside the type 2 metal wire 1 is connected. Since there is a risk of damaging it, it is necessary to remove the wired wires and cables in the type 2 metal wire 1 and install the screws 26, and then rewire the wires and cables. It was.

本発明はこのような問題を解決し、二種金属製線ぴへの穴あけ加工を不要にし、二種金属製線ぴ内の電線やケーブルを傷つけるおそれをなくし、施工検査後でも二種金属製線ぴ内の電線やケーブルの除去などの煩雑な作業を不要にした二種金属製線ぴ用アース金具を提供することを目的としている。   The present invention solves such problems, eliminates the need for drilling into the two-type metal wire, eliminates the risk of damaging the wires and cables in the two-type metal wire, and is made of the two-type metal even after construction inspection. An object of the present invention is to provide a ground metal fitting for a two-type metal wire wire that does not require complicated work such as removal of an electric wire or cable in the wire wire.

次に、この二種金属製線ぴ用アース金具４０の使用について説明する。
図２に示すように、二種金属製線ぴ１の底板２側が二種金属製線ぴ用アース金具４０のコ字状の切欠き５０、５１内に収容されるように二種金属製線ぴ用アース金具４０を被せて、基板４３の第１のネジ穴４１に螺着した締付けボルト６０を回転させて第１、第２の受け板４８、４９側へ進出させ、第１、第２の受け板４８、４９の突起４８ａ、４９ａが二種金属製線ぴ１の第１の側板３の外面に接触し、締付けボルト６０の先端部６０ａが第２の側板４の外面に接触した状態で挟み、さらに締付けボルト６０をネジ込んで強く挟持させる。 Next, the use of the ground metal fitting 40 for the two-type metal wire rod will be described.
As shown in FIG. 2, the type 2 metal wire 1 so that the bottom plate 2 side of the type 2 metal wire 1 is accommodated in the U-shaped cutouts 50 and 51 of the type 2 metal wire grounding metal fitting 40. Then, the fastening bolt 60 that is screwed into the first screw hole 41 of the substrate 43 is rotated to advance toward the first and second receiving plates 48 and 49, and the first and second The projections 48a and 49a of the receiving plates 48 and 49 are in contact with the outer surface of the first side plate 3 of the two-type metal wire rod 1, and the tip 60a of the tightening bolt 60 is in contact with the outer surface of the second side plate 4. Then, the tightening bolt 60 is screwed and firmly held.

アースボンド線３０の接続端子３１の穴３１ａにビス７０の軸部７０ａを通し、基板４３の第２のネジ穴４２にこのビス７０の軸部７０ａを螺着し、ネジ込んで基板４３とビス７０の頭部７０ｂとの間で接続端子３１を挟持させる。   The shaft portion 70a of the screw 70 is passed through the hole 31a of the connection terminal 31 of the ground bond wire 30, the shaft portion 70a of the screw 70 is screwed into the second screw hole 42 of the substrate 43, and is screwed into the board 43 and the screw. The connection terminal 31 is clamped between the 70 heads 70b.

このようにすれば、二種金属製線ぴ１の側板３、４に穴あけ加工を施すことなく二種金属製線ぴ１とアースボンド線との電気的接続を実現することができる。   In this way, the electrical connection between the two-type metal wire 1 and the earth bond wire can be realized without drilling the side plates 3 and 4 of the two-type metal wire 1.

従って、図６に示すようにプルボックス１０に二種金属製線ぴ１の一端１ａを接続した場合、アースボンド線３０の一端を図６に示すようにプルボックス１０に接続し、図２に示すようにアースボンド線３０の他端を二種金属製線ぴ１に二種金属製線ぴ用アース金具４０を用いて接続すればよい。   Therefore, when one end 1a of the two-type metal wire 1 is connected to the pull box 10 as shown in FIG. 6, one end of the earth bond wire 30 is connected to the pull box 10 as shown in FIG. As shown, the other end of the earth bond wire 30 may be connected to the type 2 metal wire 1 using the type 2 metal wire grounding metal fitting 40.

また、プルボックス１０に２本の二種金属製線ぴが接続されている場合（図示せず）、その２本の二種金属製線ぴ間をアースボンド線で電気的に接続するには、アースボンド線の両端にそれぞれ二種金属製線ぴ用アース金具４０を用いて各二種金属製線ぴ１に図２に示したのと同様に接続すればよい。   In addition, when two two-type metal wires are connected to the pull box 10 (not shown), to electrically connect the two two-type metal wires with an earth bond wire The two types of metal wires 1 may be connected to both ends of the earth bond wire in the same manner as shown in FIG.

また、図６に示すように、二種金属製線ぴ１の開口面にカバー７を被せた場合、従来では、カバー７の蓋板７ｃ、曲げ縁板７ａ、７ｂ及び二種金属製線ぴ１の側板３、４を覆い、底板２の両側を押圧するバネ性を備えたカバー固定金具８０で、カバー７を二種金属製線ぴ１に固定している。   Further, as shown in FIG. 6, when the cover 7 is put on the opening surface of the two-type metal wire 1, conventionally, the cover plate 7 c, the bent edge plates 7 a and 7 b of the cover 7 and the two-type metal wire The cover 7 is fixed to the two-metal wire rod 1 with a cover fixing metal fitting 80 that covers the side plates 3 and 4 and has a spring property that presses both sides of the bottom plate 2.

しかし、図３に示すように、二種金属製線ぴ用アース金具４０を用いて、カバー７の蓋板７ｃの外面に、第１、第２の受け板４８、４９の突起４８ａ、４９ａを接触させ、二種金属製線ぴ１の底板２に、第１のネジ穴４１に螺着した締付けボルト６０の先端６０ａを接触させ、締付けボルト６０をさらにネジ込んでカバー７と二種金属製線ぴ１を挟持すれば、図６に示したカバー固定金具８０を用いることなくカバー７を二種金属製線ぴ１に固定することができると共に、カバー７と二種金属製線ぴ１間の電気的接続も果たすことができる。   However, as shown in FIG. 3, the projections 48 a and 49 a of the first and second receiving plates 48 and 49 are formed on the outer surface of the cover plate 7 c of the cover 7 using the two-type metal wire grounding metal fitting 40. The tip 60a of the tightening bolt 60 screwed into the first screw hole 41 is brought into contact with the bottom plate 2 of the two-type metal wire 1 and the cover 7 and the two-type metal are further screwed. If the wire 1 is clamped, the cover 7 can be fixed to the two-type metal wire 1 without using the cover fixing metal fitting 80 shown in FIG. The electrical connection can also be achieved.
