Description

【0001】
【発明の属する技術分野】
本発明はレースウェイ(あるいはダクト)を開口面を互いに逆向きにした状態で連結できるようにした継ぎ金具に関する。
【0002】
【従来の技術】
例えばビル、工場、店舗、駅構内などの建造物には、レースウェイ(寸法が所定値を下回るもの)あるいはダクト(寸法が所定値以上のもの)と称される長尺のリップ溝型鋼材(以下総称してレースウェイと記す)が、配設される。
【0003】
即ち、図7に示すように複数のレースウェイ1、1、…が長手方向に連結され、支持材(例えば吊り金具2)によって例えば天井に沿って配設され、このレースウェイ1、1、…に沿って例えば照明器具3などが取付けられ、その電気コードがレースウェイ1、1、…内に沿って配線される。
【0004】
このレースウェイ1はリップ溝形鋼から成り、図7に示すように底板11と、両側板12、12と、両側板12、12の先端から内方へ折曲げ形成されたリップ縁部13、13とから成る断面コ字状で、底板11の反対側が開口面14となっている。そして、複数本のレースウェイ1、1…が長手方向に継ぎ金具20で長手方向に連結して配設される。
【0005】
このように複数のレースウェイ1、1、…を長手方向に連結するための従来の継ぎ金具20は、図8、図9に示すように、底板21と、この底板21の幅方向の両端において垂直方向に折曲げられた対向する一対の側板22、22とを備えていて、継ぎ金具20の底板21には、長手方向の両側において、それぞれ2個のネジ穴23a、23a及び23b、23bが設けられ、各ネジ穴23a及び23bには、ネジ24が、その先端24aが底板21の下面側に突出しない程度までネジ込まれた状態で予め取付けられている。
【0006】
このため、図9に示すように、継ぎ金具20の長手方向の両端部を開口面14を同じ向きにした2本のレースウェイ1a、1bの各端部の内側にレースウェイ1の底板11の内側に継ぎ金具20の底板21が重なるように挿入し、各ネジ24をそれぞれ予め取付けられた状態からさらにネジ込んで、各ネジ24の先端24aでレースウェイ1の底板11の内面を押圧することによって、継ぎ金具20の両側板22、22の上端22a、22aをレースウェイ1a、1bの両リップ縁部13、13の各基部13a、13aの内面に押圧させる。これによって、継ぎ金具20の両端に2本のレースウェイ1a、1bの各端部を固定する。
【0007】
【発明が解決しようとする課題】
しかしながら、このような構造の従来の継ぎ金具20では、図7あるいは図10に示すように2本のレースウェイ1a、1bの開口面14,14が同じ向きの状態にしか連結できない。
【0008】
このため、図7に示すように開口面14,14を上向きにして2本のレースウェイ1a、1bを連結した場合には、例えば照明器具3を左方のレースウェイ1の下面に取り付ける際には、左方のレースウェイ1aの底板11に穴(図示せず)を施工現場で加工してレースウェイ1a、1b内に配線された電気コード(図示せず)をこの穴から底板11の下面側に引き出して照明器具3に接続するか、あるいは、図7に示すように、コンセントボックス5をレースウェイ1bの上に取付けて、レースウェイ1a、1b内に配線された電気コードをコンセントボックス5に接続し、このコンセントボックス5から接続コード6を照明器具3に接続しなければならないため、作業に多大の時間がかかっていた。
【0009】
また逆に、図10に示すように開口面14,14を下向きにして2本のレースウェイ1a、1bを連結した場合には、レースウェイ1a、1bの下側に接近して盤などの障害物(図示せず)があると、電気コードが開口面14から下方へ垂れるので電気コードが障害物に引っかかって延線作業が困難となり、また図10に示すように天井面から電線管7を接続する場合には、レースウェイ1bの底板11に施工現場で穴(図示せず)を加工しなければならないので、作業に多大の時間がかかっていた。
【0010】
本発明はこのような事情に鑑みてなされたもので、レースウェイ(あるいはダクト)を開口面を互いに逆向きにした状態で連結できるようにした継ぎ金具を提供することを目的としている。
【0011】
【課題を解決するための手段】
前記目的を達成するために、本発明の請求項1のレースウェイ継ぎ金具は、
対向して設けられた互いに平行な第1、第2の側板と、
前記第1、第2の側板の長手方向の互いに反対側で且つ前記第1、第2の側板の幅方向の互いに反対側にそれぞれ設けられた第1、第2の取付け板とを備えたレースウェイ継ぎ金具であって、
前記第1、第2の取付け板にそれぞれネジ穴を設け、
開口面を互いに逆向きにしたリップ溝形鋼から成る2本のレースウェイの各端部の内側に前記第1、第2の取付け板及び前記第1、第2の側板の長手方向の両端をそれぞれ挿入し、前記ネジ穴に前記第1、第2の取付け板の内側から取り付けたネジの先端で各レースウェイの底板を押圧して前記第1、第2の側板の幅方向の前記第1、第2の取付け板と反対側の端部を各レースウェイのリップ縁部の内側に当接させて各レースウェイに固定することによって、2本のレースウェイの端部同士を互いに開口面を逆向きにした状態で接続するようにしている。
【0012】
また、請求項2のレースウェイ継ぎ金具は
前記第1の側板の長手方向の一端側において前記第1の側板の幅方向の一端から、垂直方向に前記第1の取付け板が延設され、
前記第1の取付け板の幅方向の他端から、前記第1の側板と長手方向の長さ及び幅方向の長さがほぼ等しい前記第2の側板が前記第1の側板と対向するように垂直方向に延設され、
前記第2の側板の、前記第1の取付け板に対して長手方向の反対側で且つ前記第1の側板に対して幅方向の反対側の端部から、前記第1の側板側へ垂直方向に前記第2の取付け板が延設されている。
【0013】
【発明の実施の形態】
以下、図面に基づいて本発明の実施の形態を説明する。
図1は本発明の一実施形態のレースウェイ継ぎ金具を示している。
このレースウェイ継ぎ金具30は、対向して設けられた互いに平行な第1、第2の側板31、32を備えている。
【0014】
そして、第1、第2の側板31、32の長手方向の互いに反対側で、且つ第1、第2の側板31、32の幅方向の互いに反対側に(即ち、上下互い違いに)第1、第2の取付け板33、34がそれぞれ設けられている。
【0015】
レースウェイ継ぎ金具30の第1、第2の側板31、32の外面間の距離は、レースウェイ1の両側板12、12の内面間の距離よりわずかに小に設定されている。また、第1、第2の側板31、32の高さは、レースウェイ1の底板11からリップ縁部13の基部13aの内面間の距離よりわずかに小に設定されている。
【0016】
前記第1、第2の取付け板33,34には、長手方向にそれぞれ2個のネジ穴33a,33a及び34a、34aが設けられている。
【0017】
なお、第1、第2の側板31、32の長手方向の中央において、幅方向の両端に長手方向の中央を示すための切欠き31a、31b、32a、32bが設けられている。また、第1、第2の側板31、32の長手方向の両端において、それぞれ第1、第2の取付け板33、34の反対側の角部において、レースウェイ1内に挿入しやすくするためのテーパー部31c、31d、32c、32dが設けられている。
【0018】
各ネジ穴33a、33a及び34a、34aには、図2、図3、図4に示すように、プラスチック製の保護体35(レースウェイ1内に収容される電気コードなどにネジ36の頭部36bが直接接触しないようにするために用いる。)の円形凹部35aの中心の挿通穴を通って、ネジ36が、その先端36aが第1、第2の取付け板33、34の外面側に突出しない程度までネジ込まれた状態で、予め取付けられている(図2、図3、図4はネジ先端36aが外面側へ突出した状態を描いている。)。
【0019】
このレースウェイ継ぎ金具30は例えば次のようにして作成できる。
即ち、金属板40を図5の形状に打ち抜く。そして、第2の取付け板34に相当する部分を、第2の側板32に相当する部分との境界線Cに沿って垂直に折り曲げ、さらに第1の側板31に相当する部分を、第1の取付け板33に相当する部分との境界線Aに沿って垂直に折り曲げ、第2の側板32に相当する部分を、第1の取付け板33に相当する部分との境界線Bに沿って垂直に折り曲げる。
【0020】
このようにして、第1の側板31の長手方向の一端側において第1の側板31の幅方向の一端から、垂直方向に第1の取付け板33が延設され、第1の取付け板33の幅方向の他端から、第1の側板31と長手方向の長さ及び幅方向の長さがほぼ等しい第2の側板32が第1の側板31と対向するように垂直方向に延設され、第2の側板32の、前記第1の取付け板33に対して長手方向の反対側で且つ幅方向の反対側の端部から、第1の側板31側へ垂直方向に第2の取付け板34が延設された構造のレースウェイ継ぎ金具30が作成できる。
【0021】
次に,この実施形態のレースウェイ継ぎ金具30の使用法を説明する。
前記したように、レースウェイ継ぎ金具30の第1、第2の側板31、32の外面間の距離は、レースウェイ1の両側板12、12の内面間の距離よりわずかに小に設定されて、第1、第2の側板31、32の高さは、レースウェイ1の底板11からリップ縁部13の基部13aの内面間の距離よりわずかに小に設定されているため、図2、図3に示すように、開口面14を上向きにしたレースウェイ1aの右端部の底板11の上面にレースウェイ継ぎ金具30の第1の取付け板33が重なるように、且つレースウェイ継ぎ金具30の第1、第2の側板31、32の左半部がレースウェイ1の両側板12、12の内側に重なるように、レースウェイ継ぎ金具30の左半部を挿入することができる。
【0022】
そして、第1の取付け板33のネジ穴33a、33aに予め取付けられたネジ36、36をさらにネジ込むと、各ネジ36、36の先端36a、36aが第1の取付け板33の下面から下方へ進出してレースウェイ1の底板11の上面を押圧する。このためレースウェイ継ぎ金具30は底板11から上方へ押し上げられ、レースウェイ継ぎ金具30の第1、第2の側板31、32の左半部の上端面31e、32eがレースウェイ1のリップ縁部13、13の基部13a、13aの内面に強く押圧され、これによって、レースウェイ継ぎ金具30の左半部は開口面14が上向きのレースウェイ1の右端部内に挿入された状態で固定される。
【0023】
同様に、図2、図4に示すように、開口面14を下向きにしたレースウェイ1bの左端部の底板11の下面側にレースウェイ継ぎ金具30の第2の取付け板34が重なるように、且つレースウェイ継ぎ金具30の第1、第2の側板31、32右半部がレースウェイ1bの両側板12、12の内側に重なるように、レースウェイ継ぎ金具30の右半部を挿入する。
【0024】
そして、レースウェイ継ぎ金具30の第2の取付け板34のネジ穴34a、34aに予め取付けられたネジ36、36をさらにネジ込むと、各ネジ36、36の先端36a、36aが第2の取付け板34の上面から上方へ進出してレースウェイ1bの底板11の下面を押圧する。このためレースウェイ継ぎ金具30は底板11から下方へ押し下げられ、レースウェイ継ぎ金具30の第1、第2の側板31、32の右半部の下端面31f、32fがレースウェイ1bのリップ縁部13、13の基部13a、13aの内面に強く押圧され、これによって、レースウェイ継ぎ金具30右半部は開口面14が下向きのレースウェイ1bの左端部内に挿入された状態で固定される。
【0025】
このようにして、図2に示すように、レースウェイ継ぎ金具30によって2本のレースウェイ1a、1bを開口面14、14が互いに逆向きの状態で長手方向に連結することができる。
【0026】
従って、図7を用いて説明すると、右方のレースウェイ1bの開口面14が上向きの場合に、その左方のレースウェイ1aを本発明のレースウェイ継ぎ金具30を用いてその開口面14を下向きにして連結すれば、そのままレースウェイ1a内から電気コードを照明器具3に接続できるから、左方のレースウェイ1aも開口面14を上向きにした場合のようにレースウェイ1aの底板11に穴を施工現場で加工したり、あるいは、図7に示すように、コンセントボックス5をレースウェイ1bの上に取付けたりする手間を省くことができる。
【0027】
また、図10を用いて説明すると、左方のレースウェイ1aの開口面14が下向きの場合には、右方のレースウェイ1bを本発明のレースウェイ継ぎ金具30を用いてその開口面14を上向きにして連結すれば、レースウェイ1bの下側に接近して盤などの障害物(図示せず)があっても電気コードはレースウェイ1bから下方へ垂れないので延線作業の困難がなくなり、また図10に示すように天井面から電線管7を接続する場合でも、電線管7から電気コードをそのままレースウェイ1b内に導けばいいから、レースウェイ1bの底板11に穴を加工する手間を省くことができる。
【0028】
図6は本発明の他の実施形態のレースウェイ継ぎ金具30′を示している。
このレースウェイ継ぎ金具30′では、第1、第2の取付け板33、34の中央寄りの端部に山型の折曲げ部37、38が設けられている。
【0029】
このように折曲げ部37、38を設ければ、連結される2本のレースウェイ1a、1bのリップ縁部13の端部の接続境目に、レースウェイ1a、1bを通る電気コードが直接接触して傷つくことを未然に防ぐことができる。
【0030】
【発明の効果】

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a fitting capable of connecting raceways (or ducts) with their opening surfaces being opposite to each other.
[0002]
[Prior art]
For example, in buildings such as buildings, factories, stores, and station yards, a long lip grooved steel material called a raceway (having dimensions smaller than a predetermined value) or a duct (having dimensions exceeding a predetermined value) ( Hereinafter referred to as raceway).
[0003]
That is, as shown in FIG. 7, a plurality of raceways 1, 1,... Are connected in the longitudinal direction, and are arranged along a ceiling, for example, by a support member (for example, a hanging metal 2). , For example, a lighting fixture 3 is attached, and its electric cord is wired along the inside of the raceways 1, 1,.
[0004]
This raceway 1 is made of a lip channel steel, as shown in FIG. 7, a bottom plate 11, both side plates 12, 12, and a lip edge portion 13 formed by bending inward from the tip of both side plates 12, 12. 13, and has an opening surface 14 on the opposite side of the bottom plate 11. The plurality of raceways 1, 1,... Are arranged in the longitudinal direction so as to be connected in the longitudinal direction by fittings 20.
[0005]
As shown in FIGS. 8 and 9, a conventional fitting 20 for connecting a plurality of raceways 1, 1,... In the longitudinal direction has a bottom plate 21 and two ends of the bottom plate 21 in the width direction. It has a pair of opposed side plates 22 and 22 bent in the vertical direction, and the bottom plate 21 of the fitting 20 has two screw holes 23a, 23a and 23b and 23b on both sides in the longitudinal direction. The screw 24 is provided in advance in each of the screw holes 23a and 23b in a state where the screw 24 is screwed to such an extent that the tip end 24a does not project to the lower surface side of the bottom plate 21.
[0006]
For this reason, as shown in FIG. 9, the bottom plate 11 of the raceway 1 is provided inside each end of the two raceways 1 a and 1 b with the opening surfaces 14 in the same direction at both ends in the longitudinal direction of the fitting 20. The bottom plate 21 of the fitting 20 is inserted inside so as to overlap, and each screw 24 is further screwed in from a previously attached state, and the tip 24a of each screw 24 presses the inner surface of the bottom plate 11 of the raceway 1. As a result, the upper ends 22a, 22a of both side plates 22, 22 of the joint fitting 20 are pressed against the inner surfaces of the bases 13a, 13a of the lip edges 13, 13 of the raceways 1a, 1b. Thus, the ends of the two raceways 1a and 1b are fixed to both ends of the fitting 20.
[0007]
[Problems to be solved by the invention]
However, in the conventional fitting 20 having such a structure, as shown in FIG. 7 or FIG. 10, the opening surfaces 14 of the two raceways 1a and 1b can be connected only in a state where they are in the same direction.
[0008]
For this reason, as shown in FIG. 7, when the two raceways 1a and 1b are connected with the opening surfaces 14 and 14 facing upward, for example, when the lighting fixture 3 is mounted on the lower surface of the left raceway 1 A hole (not shown) is formed in the bottom plate 11 of the left raceway 1a at a construction site, and an electric cord (not shown) wired in the raceways 1a and 1b is passed through the hole to the lower surface of the bottom plate 11 through the hole. Side, and connected to the lighting fixture 3, or as shown in FIG. 7, the outlet box 5 is mounted on the raceway 1b, and the electric cord wired in the raceways 1a and 1b is connected to the outlet box 5 as shown in FIG. , And the connection cord 6 must be connected from the outlet box 5 to the lighting fixture 3, which requires a lot of work.
[0009]
Conversely, when the two raceways 1a and 1b are connected with the opening surfaces 14 and 14 facing downward as shown in FIG. If there is an object (not shown), the electric cord hangs downward from the opening surface 14 so that the electric cord is caught by an obstacle, making it difficult to extend the wire. Further, as shown in FIG. In the case of connection, a hole (not shown) must be machined at the construction site in the bottom plate 11 of the raceway 1b, so that much time is required for the operation.
[0010]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a fitting that enables a raceway (or duct) to be connected with their opening surfaces being opposite to each other.
[0011]

Since the height of the first and second side plates 31 and 32 is set to be slightly smaller than the distance between the bottom plate 11 of the raceway 1 and the inner surface of the base 13a of the lip edge 13, FIG. As shown in FIG. 3, the first mounting plate 33 of the raceway fitting 30 overlaps the upper surface of the bottom plate 11 at the right end of the raceway 1a with the opening surface 14 facing upward, and The left half of the raceway fitting 30 can be inserted so that the left half of the first and second side plates 31 and 32 overlap the inside of the both side plates 12 and 12 of the raceway 1.
[0022]
Then, when the screws 36, 36 previously mounted in the screw holes 33 a, 33 a of the first mounting plate 33 are further screwed, the tips 36 a, 36 a of the screws 36, 36 are lowered from the lower surface of the first mounting plate 33. And presses the upper surface of the bottom plate 11 of the raceway 1. For this reason, the raceway fitting 30 is pushed upward from the bottom plate 11, and the upper end surfaces 31 e and 32 e of the left halves of the first and second side plates 31 and 32 of the raceway fitting 30 are lip edges of the raceway 1. 13, 13 are strongly pressed against the inner surfaces of the bases 13 a, 13 a, whereby the left half of the raceway fitting 30 is fixed with the opening 14 inserted into the right end of the raceway 1 facing upward.
[0023]
Similarly, as shown in FIGS. 2 and 4, the second mounting plate 34 of the raceway fitting 30 overlaps the lower surface of the bottom plate 11 at the left end of the raceway 1 b with the opening surface 14 facing downward. The right half of the raceway fitting 30 is inserted so that the right half of the first and second side plates 31 and 32 of the raceway fitting 30 overlap the inside of the side plates 12 and 12 of the raceway 1b.
[0024]
Then, when the screws 36, 36 previously attached to the screw holes 34a, 34a of the second attachment plate 34 of the raceway fitting 30 are further screwed, the tips 36a, 36a of the screws 36, 36 are attached to the second attachment plate. It advances upward from the upper surface of the plate 34 and presses the lower surface of the bottom plate 11 of the raceway 1b. For this reason, the raceway fitting 30 is pushed down from the bottom plate 11, and the lower end surfaces 31 f, 32 f of the right half of the first and second side plates 31, 32 of the raceway fitting 30 are connected to the lip edge of the raceway 1 b. 13, 13 are strongly pressed against the inner surfaces of the bases 13a, 13a, whereby the right half of the raceway fitting 30 is fixed with the opening surface 14 inserted into the left end of the downward facing raceway 1b.
[0025]
In this manner, as shown in FIG. 2, the two raceways 1a and 1b can be connected in the longitudinal direction by the raceway fittings 30 with the opening surfaces 14 and 14 being opposite to each other.
[0026]
Therefore, referring to FIG. 7, when the opening surface 14 of the right raceway 1b faces upward, the left raceway 1a is connected to the opening surface 14 using the raceway fitting 30 of the present invention. If the connection is made downward, the electric cord can be directly connected to the lighting equipment 3 from within the raceway 1a. Therefore, the left raceway 1a also has a hole in the bottom plate 11 of the raceway 1a as in the case where the opening surface 14 is turned upward. On the construction site, or as shown in FIG. 7, it is possible to save the trouble of mounting the outlet box 5 on the raceway 1b.
[0027]
Referring to FIG. 10, when the opening surface 14 of the left raceway 1a faces downward, the opening surface 14 of the right raceway 1b is changed by using the raceway fitting 30 of the present invention. If the connection is made upward, even if there is an obstacle (not shown) such as a panel approaching the lower side of the raceway 1b, the electric cord does not hang down from the raceway 1b, so that there is no difficulty in wire drawing work. Also, as shown in FIG. 10, even when the conduit 7 is connected from the ceiling surface, the electric cord from the conduit 7 can be guided into the raceway 1b as it is, so that it is troublesome to form a hole in the bottom plate 11 of the raceway 1b. Can be omitted.
[0028]
FIG. 6 shows a raceway fitting 30 'according to another embodiment of the present invention.
In the raceway fitting 30 ′, the first and second mounting plates 33 and 34 are provided with mountain-shaped bent portions 37 and 38 at the ends near the center.
[0029]
When the bent portions 37 and 38 are provided in this manner, the electric cord passing through the raceways 1a and 1b directly contacts the connection boundary between the ends of the lip edges 13 of the two raceways 1a and 1b to be connected. It can be prevented from being damaged.
[0030]
【The invention's effect】
As described above, according to the present invention, it is possible to connect two raceways (or ducts) with their opening surfaces being opposite to each other.
