To provide a fixing tool that can easily fix and separate an existing formwork and a support rod in one operation.SOLUTION: A fixing tool 1 connecting a support rod 3 leaning against a formwork 2 to the formwork 2 includes: an engaging arm 4 inserted into an opening 2c provided on one face of the formwork 2; a main shaft 15 whose one end is connected by the engaging arm 4 and a rotating shaft 13 and which has a thread groove 37 formed on its surface; a holding member 16 inserted through the main shaft 15 and holding the support rod 3; and a nut 23 assembled to the main shaft 15 and tightening the holding member 16 to the support rod 3. The engaging arm 4 has a first engaging portion 6 that engages one surface of the formwork 2 from one side, on one end side, and a second engaging portion 10 that engages one surface of the formwork from the other side, on the other end side. By tightening the holding member 16 with the nut 23 and relatively pulling up the main shaft 15, the engaging arm 4 is moved around the rotating shaft 13, to make the first engaging portion 6 and the second engaging portion 10 of the engaging arm 4 engage one surface of the formwork 2.SELECTED DRAWING: Figure 3
【課題】既存の型枠と支持棒とを、一動作で簡単に固定および分離できる固定具を提供する。【解決手段】本発明における固定具は、に立て掛けた支持棒３を型枠２に連結する固定具１であって、型枠２の一面に設けられる開口部２ｃに差し込まれる係合腕４と、係合腕４と回転軸１３によって一端が連結され、表面にネジ溝３７が形成された主軸１５と、主軸１５に挿通され支持棒３を保持する保持部材１６と、主軸１５に組み付けられ保持部材１６を支持棒３に締め付けるナット２３と、を備え、係合腕４は、一端側に型枠２の一面に一方側から係合する第１係合部６と、他端側に型枠の一面に他方側から係合する第２係合部１０と、を有し、ナット２３で保持部材１６を締め付けて、主軸１５を相対的に引き上げることで回転軸１３を中心に係合腕４を回動させ、係合腕４の第１係合部６と第２係合部１０を型枠２の一面に係合させる。【選択図】図３
