とを特徴とするコンクリート型枠の締付け装置。The screw shaft portion 4 of the cone 3 is projected from the hole 5 of the concrete formwork 1 to the outside of the formwork, and the proximal end face of the formwork clamping rod 6 having the collar 7 is attached to the protruding end of the screw shaft portion 4. The concrete formwork 1 is assembled between the flange 7 and the cone 3 by screwing together the female threaded hole 8 provided.
, and selectively drive the wedge 16 into either the first wedge through hole 11 or the second wedge through hole 12 provided side by side on the formwork clamping rod 6 , so that only the vertical flap material 9 is removed.
Alternatively, in a concrete formwork tightening device in which the vertical and horizontal beams 9 and 10 are attached to the outside of the concrete formwork 1, it has a wedge receiver 13 attached to the outer periphery of the formwork tightening rod 6, This wedge catch 13 has an inner end surface 13a on the proximal side butted against the back side of the collar 7, and a formwork tightening rod protrudes from a point at a distance equal to the thickness of the vertical flap member 9. A wedge through hole 14 is provided on the outside in the first direction.
It is characterized in that it is provided in communication with the wedge through hole 11, and is configured such that the outer end surface 13b on the tip side matches a position equal to the combined thickness of the vertical and horizontal beams 9 and 10. A tightening device for concrete formwork.
