Description

本発明は、バスダクトを容易に固定できる、施工性に優れるバスダクト用固定金具に関する。   The present invention relates to a bus duct fixing metal fitting that can easily fix a bus duct and has excellent workability.

バスダクトは導体を函体（ハウジング）内に収容して構成されたもので、電力ケーブルに較べて火災や磁束漏洩が起き難いため工場やビルの主電力供給ラインとして広く用いられている（特許文献１）。   A bus duct is configured by housing a conductor in a box (housing), and is widely used as a main power supply line in factories and buildings because it is less likely to cause fire and magnetic flux leakage than a power cable (Patent Literature) 1).

ところで、前記バスダクトは、床或いは天井から吊り下げられた受け架台などの設置面に固定金具により固定して設置されている。
前記固定金具には、従来より、図３（イ）、（ロ）に示すように、一対の分割片１１、１２をそれぞれバスダクト３の両側に配し、前記一対の分割片１１、１２の頂部をバスダクト３頂面側でボルト締めして連結し、基部のボルト穴部１１ｂ、１２ｂをそれぞれバスダクト設置面にボルト締めする３点ボルト締めの固定金具が用いられていた。しかし、この固定金具は、ボルト締め箇所が３箇所もあり、しかも上方に障害物が存在する場合は頂部のボルトが締め難く、施工性に問題があった。 By the way, the bus duct is installed by being fixed to an installation surface such as a cradle suspended from a floor or a ceiling by a fixing bracket.
Conventionally, as shown in FIGS. 3 (a) and 3 (b), a pair of divided pieces 11 and 12 are respectively arranged on both sides of the bus duct 3, and the top portions of the pair of divided pieces 11 and 12 are provided on the fixing bracket. Are fixed on the top surface side of the bus duct 3 by bolting, and fixing bolts for three-point bolting are used to bolt the bolt hole portions 11b and 12b of the base to the bus duct installation surface. However, this fixing bracket has three bolt tightening points, and when there is an obstacle on the upper side, it is difficult to tighten the top bolt, and there is a problem in workability.

そこで、図４（イ）、（ロ）に示すような、頂部が連結した一体ものの断面π型の固定金具１３が提案された。しかし、この固定金具は、一体もので幅があるため、バスダクトの上方に障害物が存在する場合は固定金具１３をバスダクト３の所定箇所に配置するのに手間を要し、場合によっては固定金具１３が障害物と擦れ合って塗装面に傷が付いたりし、やはり施工性に問題があった。   In view of this, a monolithic fixing bracket 13 having a π-shaped cross section with the top connected as shown in FIGS. 4A and 4B has been proposed. However, since this fixing bracket is integrated and has a width, if there is an obstacle above the bus duct, it takes time to arrange the fixing bracket 13 at a predetermined position of the bus duct 3. No. 13 rubbed against the obstacle and scratched the painted surface, and there was still a problem in workability.

特開２００４−１０４８９６号公報JP 2004-104896 A

本発明は、施工性に優れるバスダクト用固定金具の提供を目的とする。   An object of this invention is to provide the metal fitting for bus ducts which is excellent in workability.

The invention according to claim 1 comprises a pair of divided pieces each provided with a locking portion at the top and a bolt hole portion at the base, each of the pair of divided pieces being disposed on both sides of the bus duct, The top portion includes an inner bent portion that is bent inward at a right angle and is halved in width, and the locking portion that is formed by vertically bending the tip of the inner bent portion upward, The locking portion is locked on the top surface side of the bus duct so as to contact each other over the entire length in the width direction and the vertical direction of the divided pieces, and the bolt hole portion is fixed to the bus duct installation surface with a bolt. It is a metal fitting for bus ducts.

本発明のバスダクト用固定金具は、一対の分割片からなるのでバスダクトの上方に障害物が存在していてもバスダクトの所定箇所に容易に配置できる。また前記一対の分割片は係止部を係止して連結するので、上方に障害物が存在していても容易に連結できる。従って施工性に優れる。   Since the bus duct fixing bracket of the present invention is composed of a pair of divided pieces, it can be easily arranged at a predetermined location of the bus duct even if an obstacle exists above the bus duct. Further, since the pair of divided pieces are connected by locking the locking portions, they can be easily connected even if an obstacle exists above. Therefore, it is excellent in workability.

以下に、本発明を、図を参照して具体的に説明する。
なお、本発明を説明するための全図において符号の繰り返しの説明は省略する。
図１は本発明の固定金具の実施形態を示す斜視図である。
この固定金具は、一対の分割片１、２からなり、前記分割片１、２は、それぞれ頂部が内側に直角に曲げられて内曲げ部１ａ、２ａが形成され、その先がさらに上方に直角に曲げられて係止部１ｂ、２ｂが設けられている。一方、基部は外側に直角に曲げられてそれぞれ外曲げ部１ｃ、２ｃが形成され、そこにそれぞれボルト穴１ｄ、２ｄが設けられている。内曲げ部１ａ、２ａはそれぞれ幅が半減されていて、分割片１、２を相互に係止したときに、両係止部１ｂ、２ｂが全長に亘り接触するように形成されている。 Hereinafter, the present invention will be specifically described with reference to the drawings.
Note that repeated descriptions of reference numerals are omitted in all drawings for explaining the present invention.
FIG. 1 is a perspective view showing an embodiment of a fixing metal fitting of the present invention.
The fixing bracket is composed of a pair of divided pieces 1 and 2, and the divided pieces 1 and 2 are respectively bent at the top at right angles to form inner bent portions 1 a and 2 a, and the tip of the divided pieces 1 and 2 is further upwardly perpendicular. The locking portions 1b and 2b are provided. On the other hand, the base is bent outward at a right angle to form outer bent portions 1c and 2c, respectively, where bolt holes 1d and 2d are provided, respectively. The inner bent portions 1a and 2a are each halved in width, and are formed such that when the divided pieces 1 and 2 are locked to each other, both the locking portions 1b and 2b are in contact with each other over the entire length.

図２は本発明の固定金具の使用形態を示す（イ）正面説明図、（ロ）平面図、（ハ）側面図である。
バスダクト３の両側に一対の分割片１、２が配されており、その係止部１ｂ、２ｂはバスダクト３の頂面３ａ側で相互に係止して連結されている。またボルト穴部１ｄ、２ｄは受け架台４の上面（バスダクト設置面）４ａにボルト５およびナット６により固定されている。図２で７は導体、８は導体を収容する函体、９は導体７を函体８に取り付けるためのビス（ねじ釘）、９ａは雌ねじ片、１０は受け架台４を天井（図示せず）に吊り下げるための吊りボルトである。１４は吊りボルト１０を受け架台４に固定するための固定部材である。 FIGS. 2A and 2B are (a) front explanatory view, (b) a plan view, and (c) a side view showing a usage form of the fixing bracket of the present invention.
A pair of divided pieces 1 and 2 are disposed on both sides of the bus duct 3, and the locking portions 1 b and 2 b are locked and connected to each other on the top surface 3 a side of the bus duct 3. The bolt hole portions 1 d and 2 d are fixed to the upper surface (bus duct installation surface) 4 a of the receiving stand 4 by bolts 5 and nuts 6. In FIG. 2, 7 is a conductor, 8 is a box for accommodating the conductor, 9 is a screw (screw nail) for attaching the conductor 7 to the box 8, 9a is a female screw piece, 10 is a ceiling of the receiving stand 4 (not shown) ) Is a hanging bolt for hanging. Reference numeral 14 denotes a fixing member for receiving the suspension bolt 10 and fixing it to the gantry 4.

図２に示した固定構造は、例えば、一方の分割片１をバスダクト３の一側面に配置し、その外曲げ部１ｃを架台４上面４ａにボルト５とナット６により固定し、次いで他方の分割片２をバスダクトの他側面に配し、この係止部２ｂを分割片１の係止部１ｂに係止させ、次いでその外曲げ部２ｃを架台４上面４ａにボルト５とナット６により固定することにより容易に形成できる。   In the fixing structure shown in FIG. 2, for example, one divided piece 1 is arranged on one side of the bus duct 3, and the outer bent portion 1c is fixed to the upper surface 4a of the gantry 4 with bolts 5 and nuts 6, and then the other divided piece. The piece 2 is arranged on the other side surface of the bus duct, the engaging portion 2b is engaged with the engaging portion 1b of the divided piece 1, and then the outer bent portion 2c is fixed to the upper surface 4a of the gantry 4 with bolts 5 and nuts 6. Can be easily formed.

係止部１ｂ、２ｂを係止させたときの分割片１、２の間隔Ｄ（図１参照）はバスダクト３の幅より若干小さくしておくとバスダクト３の固定がより強固になされる。前記間隔Ｄがバスダクト３の幅より大きいときは係止部１ｂ、２ｂ間にライナを挟むことにより対処できる。   If the distance D (see FIG. 1) between the split pieces 1 and 2 when the locking portions 1b and 2b are locked is slightly smaller than the width of the bus duct 3, the bus duct 3 is more firmly fixed. When the distance D is larger than the width of the bus duct 3, it can be dealt with by inserting a liner between the locking portions 1b and 2b.

本発明の固定金具は、切削などの機械加工、板金加工、鋳造、溶接或いはろう付けなどの任意の方法により、或いはこれらを組み合わせることにより容易に製造できる。   The fixing bracket of the present invention can be easily manufactured by any method such as machining such as cutting, sheet metal processing, casting, welding or brazing, or a combination thereof.

本発明において、係止部の形状は相互に係止できる形状であれば任意である。また固定金具の材料には、アルミ合金材、鉄材などが強度およびコストの点で推奨される。   In the present invention, the shape of the locking portion is arbitrary as long as it can be locked to each other. In addition, aluminum alloy materials, iron materials, etc. are recommended as materials for the fixing metal in terms of strength and cost.
