実施形態を示した図１は、一対の型枠１，２で形成された出隅部分を、一対のＬ形鋼３，４で支持したもので、上記Ｌ形鋼３，４は、一方の平坦部３ａ，４ａと他方の平坦部３ｂ，４ｂとを直角に交差させたものである。
そして、上記Ｌ形鋼３，４は、型枠１，２の出隅部分に合わせて交差させるとともに、それらの平坦部３ａ，４ａを互いに重ね合わせて、その重ね合わせ部分におけるクランプポイントＰを、図２に示したクランプ部材Ｃでクランプするものである。 In FIG. 1 showing the embodiment, the protruding corner portion formed by a pair of molds 1 and 2 is supported by a pair of L-shaped steels 3 and 4, and the L-shaped steels 3 and 4 The flat portions 3a, 4a and the other flat portions 3b, 4b are crossed at right angles.
The L-shaped steels 3 and 4 intersect with the projecting corners of the molds 1 and 2 and overlap the flat portions 3a and 4a with each other. It clamps with the clamp member C shown in FIG.

上記クランプ部材Ｃは、ほぼＣ字状にした本体５の一端を押圧部５ａとする一方、この押圧部５ａと対向する他端には、締付ボルト６を貫通させている。そして、この締付ボルト６を締付方向に回すと、締付ボルト６と上記押圧部５ａとの対向間隔が狭くなり、それら押圧部５ａと締付ボルト６の先端との間隔が小さくなり、その間隔におけるＬ形鋼の平坦部をクランプできるようにしたものである。
なお、このクランプ部材Ｃは、上記押圧部５ａにも図示していない締付ボルトを設け、この締付ボルトと上記締付ボルト６で、上記間隔における部材をクランプできるようにしたものでもよい。 In the clamp member C, one end of a substantially C-shaped main body 5 is used as a pressing portion 5a, and a fastening bolt 6 is passed through the other end facing the pressing portion 5a. When the tightening bolt 6 is turned in the tightening direction, the facing distance between the tightening bolt 6 and the pressing portion 5a is reduced, and the distance between the pressing portion 5a and the tip of the tightening bolt 6 is decreased. The flat portion of the L-shaped steel at the interval can be clamped.
The clamp member C may be provided with a clamping bolt (not shown) also in the pressing portion 5a so that the member at the interval can be clamped by the clamping bolt and the clamping bolt 6.

そして、上記のように互いに交差させた平坦部３ａ，４ａにおけるクランプポイントＰを、上記押圧部５ａと締付ボルト６との間に挟んで、締付ボルト６を締付方向に回せば、上記平坦部３ａ，４ａのクランプポイントＰがクランプ部材Ｃでしっかりとクランプされる。
なお、上記図１において一対のＬ形鋼３，４を直角に交差させたが、直角である必要はなく、あくまでも型枠１，２が形成する出隅部の角度に合わせて、これらＬ形鋼３，４を交差させればよいこと当然である。 Then, the clamp point P in the flat portions 3a and 4a crossing each other as described above is sandwiched between the pressing portion 5a and the tightening bolt 6 and the tightening bolt 6 is turned in the tightening direction. The clamp point P of the flat portions 3a and 4a is firmly clamped by the clamp member C.
In FIG. 1, the pair of L-shaped steels 3 and 4 intersect each other at right angles. However, the L-shaped steels 3 and 4 do not need to be at right angles. Of course, the steels 3 and 4 may be crossed.

図３は一対のＬ形鋼３，４を直列にするとともに、それらのＬ字が互いに反対向きになるようにして平坦部３ａ及び４ｂを重ね合わせ、それらの重ね合わせ部分におけるクランプポイントＰを、上記クランプ部材Ｃでクランプするものである。なお、クランプの強度を上げるためには、クランプポイントＰを多くして、たくさんのクランプ部材Ｃでクランプすることが望ましい。   FIG. 3 shows a pair of L-shaped steels 3 and 4 in series, and the flat portions 3a and 4b are overlapped so that their L-shapes are opposite to each other. The clamp member C is used for clamping. In addition, in order to raise the intensity | strength of a clamp, it is desirable to clamp with many clamp members C by increasing the clamp point P. As shown in FIG.

図４は一対のＬ形鋼３，４を直列にするとともに、それらのＬ字の向きを同じにして、平坦部３ａと４ａ、３ｂと４ｂを重ね合わせたもので、その他は上記図３の場合と同じである。
一対のＬ形鋼３，４を図３のように重ね合わせるか、あるいは図４のように重ね合わせるかは、建造物の特性や建設現場の状況に応じて選択すればよい。 FIG. 4 shows a pair of L-shaped steels 3 and 4 arranged in series, and their L-shaped directions are the same, and flat portions 3a and 4a, 3b and 4b are overlapped. Same as the case.
Whether the pair of L-shaped steels 3 and 4 are overlapped as shown in FIG. 3 or as shown in FIG. 4 may be selected according to the characteristics of the building and the situation of the construction site.

図５は、一対の型枠１，２で形成された出隅部分を、図１の場合と同様に、一対のＬ形鋼３，４で支持したもので、上記Ｌ形鋼３，４は、一方の平坦部３ａ，４ａと他方の平坦部３ｂ，４ｂとを直角に交差させている。
さらに、この図５においては、互いに交差するＬ形鋼３，４の平坦部３ａ，４ａの間に、補強用の短いＬ形鋼７をかけ渡すとともに、Ｌ形鋼３の平坦部３ａと補強用のＬ形鋼７の平坦部７ａ、Ｌ形鋼４の平坦部４ａと補強用のＬ形鋼７の平坦部７ａを重ね合わせている。 FIG. 5 shows a case where the protruding corner portion formed by the pair of molds 1 and 2 is supported by a pair of L-shaped steels 3 and 4 as in the case of FIG. The one flat portion 3a, 4a and the other flat portion 3b, 4b intersect at a right angle.
Further, in FIG. 5, the short L-shaped steel 7 for reinforcement is passed between the flat portions 3 a and 4 a of the L-shaped steels 3 and 4 intersecting with each other, and the flat portion 3 a and the reinforcing portions of the L-shaped steel 3 are reinforced. The flat portion 7a of the L-shaped steel 7 and the flat portion 4a of the L-shaped steel 4 and the flat portion 7a of the reinforcing L-shaped steel 7 are overlapped.

そして、上記Ｌ形鋼３の平坦部３ａと補強用のＬ形鋼７の平坦部７ａとの重ね合わせ部におけるクランプポイントＰを、クランプ部材Ｃの上記押圧部５ａと締付ボルト６との間に挟んで、締付ボルト６を締付方向に回せば、上記平坦部３ａ，７ａのそれぞれがクランプ部材Ｃでしっかりとクランプされる。
また、上記Ｌ形鋼４の平坦部４ａと補強用のＬ形鋼７の平坦部７ａとの重ね合わせ部を、クランプ部材Ｃの上記押圧部５ａと締付ボルト６との間に挟んで、締付ボルト６を締付方向に回せば、上記平坦部４ａ，７ａのそれぞれがクランプ部材Ｃでしっかりとクランプされる。
上記のようにした図５の場合には、型枠１，２で形成された出隅部分において、３本のＬ形鋼３，４，７が三角形を形成して互いに交差するので、その部分における強度は確実に大きくなる。 And the clamp point P in the overlapping part of the flat portion 3a of the L-shaped steel 3 and the flat portion 7a of the reinforcing L-shaped steel 7 is set between the pressing portion 5a of the clamp member C and the tightening bolt 6. When the clamping bolt 6 is turned in the clamping direction, each of the flat portions 3a and 7a is firmly clamped by the clamp member C.
Further, the overlapping portion of the flat portion 4a of the L-shaped steel 4 and the flat portion 7a of the reinforcing L-shaped steel 7 is sandwiched between the pressing portion 5a of the clamp member C and the fastening bolt 6, When the tightening bolt 6 is turned in the tightening direction, each of the flat portions 4a and 7a is firmly clamped by the clamp member C.
In the case of FIG. 5 as described above, since the three L-shaped steels 3, 4 and 7 form a triangle and intersect each other in the protruding corner portion formed by the molds 1 and 2, that portion The strength at is certainly increased.

図６は、一対のＬ形鋼３，４の先端を、それらの交差部分よりも大きく突出させ、その突出部分に補強用のＬ形鋼７をかけ渡したものである。すなわち、上記のように交差部分よりも大きく突出したＬ形鋼３，４の平坦部３ａ，４ａの間に、補強用のＬ形鋼７をかけ渡すとともに、このＬ形鋼７の平坦部７ａと、上記平坦部３ａ，４ａとの重なり合い部分をクランプポイントＰとし、これらクランプポイントＰを上記クランプ部材Ｃでクランプしたものである。
この図６の場合にも、３本のＬ形鋼３，４，７が三角形を形成して互いに交差するので、その部分における強度は確実に大きくなる。 In FIG. 6, the ends of the pair of L-shaped steels 3 and 4 are protruded larger than their intersecting portions, and the reinforcing L-shaped steel 7 is passed over the protruding portions. That is, the reinforcing L-shaped steel 7 is passed between the flat portions 3a and 4a of the L-shaped steels 3 and 4 protruding larger than the intersecting portion as described above, and the flat portion 7a of the L-shaped steel 7 is also provided. And the overlapping part with the said flat parts 3a and 4a is made into the clamp point P, and these clamp points P are clamped with the said clamp member C.
Also in the case of FIG. 6, the three L-shaped steels 3, 4, 7 form a triangle and intersect each other, so that the strength at that portion is reliably increased.

図７は、一対の型枠１，２で形成された入隅部分を、一対のＬ形鋼３，４で支持したもので、上記Ｌ形鋼３，４は、一方の平坦部３ａの先端と他方の平坦部４ａの先端とを重ね合わせて、それらを直角に交差させたものである。そして、上記平坦部３ａ，４ａの間には、補強用のＬ形鋼７をかけ渡すとともに、このＬ形鋼７の平坦部７ａと、上記平坦部３ａ，４ａとの重なり合い部分をクランプポイントＰとし、これらクランプポイントＰを上記クランプ部材Ｃでクランプしたものである。
この図７の場合にも、３本のＬ形鋼３，４，７が三角形を形成して互いに交差するので、その部分における強度は確実に大きくなる。 FIG. 7 is a view in which a corner portion formed by a pair of molds 1 and 2 is supported by a pair of L-shaped steels 3 and 4, and the L-shaped steels 3 and 4 are the tip of one flat portion 3 a And the tip of the other flat portion 4a are overlapped and intersected at a right angle. The reinforcing L-shaped steel 7 is passed between the flat portions 3a and 4a, and the flat portion 7a of the L-shaped steel 7 and the overlapping portion of the flat portions 3a and 4a are clamp points P. These clamp points P are clamped by the clamp member C.
Also in the case of FIG. 7, the three L-shaped steels 3, 4, and 7 form a triangle and intersect each other, so that the strength at that portion is surely increased.
