A device for controlling applicability of a friction wedge during repair contains a template, which is a frame consisting of vertical, horizontal and inclined surfaces, which has an angle to the vertical surface equal to the angle of inclination of the faces of friction wedge. The device additionally comprises a bracket. In the case the frame is unclosed from below, the bracket is made with possibility of resting against the side face of wedge that is wear-free, on inclined and vertical surfaces of the frame grooves are made and the bracket is made with lugs on the lateral surfaces, which are mounted in grooves of inclined and vertical surfaces of the frame with provision of fixing the frame at a given distance to the lateral edge of wedge. |
