リップで緊結する枠組みが一般的である。(Prior Art) Conventionally, in a concrete formwork frame, as shown in FIG. 8, a circular-diameter separator insertion hole 18 is opened in a formwork A, A ′ to be used in advance, and one formwork is provided for each juxtaposed step. A separator 19 having cones 20 attached to both ends is inserted into A, opposite molds A ′ are arranged side by side, a separator connector 21 is connected to an end of the separator 19, and a vertical / horizontal direction is formed on the back surface of the mold. Attach the scraps 22 and 23, insert the washer 24 into the separator connector 21, and wedge the washer.
Type 25 or tighten nut 26 to form A,
Tighten from the back of A'or as shown in Fig. 7,
In general, a frame in which a temporary separator 28 is suspended in a clip insertion hole 27 provided in an adjacent portion of the facing molds B and B'and is tightly connected with a clip together with the adjacent molds.
しかし、前者の方法には鋼製・木製を問わず、枠組み毎
に使用型枠にセパレータの挿通孔を開けねばならず、そ
のため型枠の解体後、次回転用のためには挿通孔の修復
を必要とし、型枠の維持管理コストが嵩む経済的な問題
があった。However, for the former method, regardless of whether it is made of steel or wood, it is necessary to open a separator insertion hole in the used formwork for each frame, so after dismantling the formwork, repair the insertion hole for the next rotation. It was necessary and there was an economic problem that the maintenance cost of the formwork increased.
さらに、並置段毎にセパレータを挿通させて枠組みを行
わなければならず、大組み後にセパレータを型枠背面よ
り挿通させることができないため、枠組み内部が狭かっ
たり枠組み高が上がればセパレータ設置に困難をきた
し、仮設材の増加や作業効率の低下を招いてきた。Furthermore, the separator must be inserted for each juxtaposed step, and the separator cannot be inserted from the back of the formwork after large-scale assembly, so if the inside of the frame is narrow or the height of the frame is high, it is difficult to install the separator. However, this has led to an increase in temporary materials and a decrease in work efficiency.

鉄筋が障壁となりセパレータが所定の位置に差し込めな
いケースが往々にして起こり、セパレータの位置の変更
を余儀無くされるケースが多かった。Also, in the latter case, when the reinforcing bar is set inside the formwork together with the former, the horizontal reinforcing bar displaces the position to some extent, but the vertical reinforcing bar acts as a barrier and the separator often cannot be inserted in the predetermined position. , In many cases, the position of the separator had to be changed.
