To provide a connecting bracket for connecting adjacent stiles to each other at a position where concrete formworks are adjacent to each other.SOLUTION: A U-shaped main body 1 comprises a pair of L-shaped holding members 5 and 6 including bottom portions 7 and 8 and holding portions 9 and 10 continuously provided from outer ends of the bottom portions. A fastening bolt nut 3 comprises: a bolt 11 that is detented by the inner bottom portion 7 and penetrates the outer bottom portion 8 of the two bottom portions 7 and 8 that overlap each other; and a nut 12 that is screwed into the bolt 11 to press and fix the outer bottom portion 8 to the inner bottom portion 7. A spring material 2 is interposed between the outer bottom portion 8 and the nut 12 and spreads between the outer bottom portion 8 and the nut 12. When the nut 12 is loosened, it is possible to separate the holding portions 9 and 10 of the pair of L-shaped holding members 5 and 6 from each other against the urging force of the spring member 2. By tightening the nut 12, a distance between the two holding portions 9 and 10 is narrowed to the minimum distance.SELECTED DRAWING: Figure 1
【課題】コンクリート型枠が互いに隣接する箇所において、互いに隣接する桟木どうしを連結するための連結金具を提供する。【解決手段】コの字形本体１は、底辺部７，８と当該底辺部の外端から連設された挟持部９，１０から成る一対のＬ形挟持部材５，６から成り、締結用ボルトナット３は、互いに重なる両底辺部７，８の内、内側になる底辺部７に回り止めされ且つ外側になる底辺部８を貫通するボルト１１と、当該ボルト１１に螺嵌して外側の底辺部８を内側の底辺部７に押圧固定するナット１２から成り、バネ材２は、外側になる底辺部８とナット１２との間に介在されて当該外側になる底辺部８とナット１２との間を押し広げるものであって、ナット１２を弛めた状態では、バネ材２の付勢力に抗して一対のＬ形挟持部材５，６の挟持部９，１０を互いに離間させることを可能にし、ナット１２の締め込みにより、両挟持部９，１０間の間隔が最小間隔まで狭められる。【選択図】図１
