<p>PROBLEM TO BE SOLVED: To push in a wedge easily, making use of a pusher as it is, by providing an anchor clamp with a band-shaped thick part such that it surrounds the linear groove side of the clamp body, and providing the thick part with a recess with which the hooking claw of a pusher being used when pushing in a wedge body is to be engaged. SOLUTION: The side plates 23 and 23 of a pusher (a) are positioned on both sides of the clamp body 1, and then a hooking claw 23a is engaged with a recess 3a. Then, a hydraulic pump is driven in this condition, whereupon the wedge body is pushed in the clamp body by a head. At the time of this pushing of the wedge body, the end 23a of the side plate 23 provided with the hooking claw 23a abuts against it at a point where the axis of the pressing force of the wedge body working and a side a cross each other, since the end face 2a of the side of the strip thick part 2 is made circular. Accordingly, the direction of the push in of the wedge body and the direction of push in of the head conform to each other completely, so this can prevent such a trouble that the side plate 23 comes off from the clamp body 1.</p> |
