用楔の緊締工具。 Of the mounting holes drilled at both ends, at least one of the mounting holes on the side of the main plate is formed into a long slot, and a connecting fitting formed by bending an L-shaped locking part from one end edge of the main plate is connected to the mounting hole adjacent to the main plate. A bolt inserted into the mounting hole of the connecting fitting is screwed into a nut that abuts on each side of the concrete block and is fixed to each block, and a bolt is inserted between the bolt and the L-shaped locking part. , a notch for the insertion of the bolt is formed on the inner edge, the outer peripheral edge on the other side is formed into an eccentric arc-shaped surface whose radius from the center of the notch gradually changes, and a wedge is formed at the end of the arc-shaped surface. In a concrete block connecting device formed by interposing a wedge with a protruding rotating protrusion, the end of the bolt inserted into the notch of the wedge and screwed into the nut of the concrete block is attached to the head. A tightening tool for a wedge for connecting concrete blocks, characterized in that a key-shaped engagement piece that engages with a wedge rotation protrusion on the wedge projects from the tip of a rotation handle having a rotation handle.
