点の解決を図つたものである。 The present invention has a U-shaped bottomed circular hole in which the outer end of one plate has a semicircular part at the back and one end of the square part opens at the end surface of the plate, and the bottom of this square hole. A small circular hole with a diameter smaller than that of the semicircular portion is bored in the center of the semicircular portion, and the opening end surface of the square hole is closed with a rim material attached to the end surface of the plate, and the square hole is A washer having the same shape as this and having a countersunk hole that matches the small circular hole is fitted, and a coupling screw having a countersunk head is inserted into this washer, and the other plate is perpendicular to one plate. The above-mentioned problem is solved by screwing it into the end face of the holder.

[Effect]

本考案によれば、方円孔を穿設する際、板の端
縁に細い縁が生せず、そのため、加工が容易であ
り、細い縁がないので、結合ねじを締付ても、板
体の裂け割れが生ずる恐れはない。 According to the present invention, when drilling a rectangular hole, a thin edge does not form on the edge of the plate, making it easy to process, and since there is no thin edge, even when the coupling screw is tightened, There is no risk of splitting the body.

〔Example〕

第１図と第２図は、本考案の装置を示すもの
で、１，２は、それぞれ上記５１，５２と同様の
水平板体と垂直板体、３は、上記５３と同様の縁
材である。 1 and 2 show the device of the present invention, where 1 and 2 are horizontal and vertical plates similar to 51 and 52 above, respectively, and 3 is a border material similar to 53 above. be.

水平板体１の上面端部には、上記大円孔５４に
代えて、Ｕ字形の有底方円孔４が、その半円部４
ａを奥部とし、方形部４ｂの一端が、板体１の端
面に開口するようにして穿設されている。 At the upper end of the horizontal plate 1, in place of the large circular hole 54, there is a U-shaped circular hole 4 with a bottom in its semicircular portion 4.
A is the inner part, and one end of the rectangular part 4b is bored into the end surface of the plate 1 so as to open therein.

方円孔４の底面の半円部４ａの中央には、上記
５５と同様の、半円部４ａより小径の小円孔５が
穿設されている。 In the center of the semicircular portion 4a on the bottom surface of the square hole 4, a small circular hole 5 similar to 55 described above and having a smaller diameter than the semicircular portion 4a is bored.

方円孔４には、これと同形の座金６が嵌合さ
れ、座金６には、上記小円孔５と同軸をなす皿孔
７が穿設されている。 A washer 6 of the same shape is fitted into the square circular hole 4, and a countersunk hole 7 coaxial with the small circular hole 5 is bored in the washer 6.

両板体１，２は、上方より、水平板体１の皿孔
７と小円孔５を挿通する皿頭付結合ねじ８を、垂
直板体２の端面に埋設した、上記５９と同様のイ
ンサートナツト９に螺締することにより結合され
ている。 Both plates 1 and 2 are similar to the above-mentioned 59, in which a countersunk coupling screw 8, which is inserted from above through the countersunk hole 7 and small circular hole 5 of the horizontal plate 1, is embedded in the end face of the vertical plate 2. It is connected by screwing into the insert nut 9.

[Effect of idea]

本考案においては、座金が方円形をしているの
で、これをはめ込む方円孔を穿設する際、板の端
縁に細い縁が生せず、そのため加工が容易であ
る。 In the present invention, since the washer has a rectangular shape, when drilling a rectangular hole into which the washer is inserted, no thin edges are formed on the edges of the plate, and therefore machining is easy.

また、細い縁がないので、結合ねじを締付ける
際に、板体の一部に裂け割れが生ずる恐れがな
く、板厚の薄い板体を直角に結合するのに甚だ効
果がある。 Furthermore, since there is no thin edge, there is no risk of cracking or splitting a part of the plate when tightening the connecting screw, and this is extremely effective in joining thin plates at right angles.
