FIELD: machine building.SUBSTANCE: proposed wedge comprises body shaped to prismatic-shape metal plate. Said plate has two working surfaces converging at acute angle, two side surfaces shaped to rectangular trapezoids, bases shaped to similar rectangles located in parallel planes, and retainer. Plate body has lengthwise cut-out dividing its working surfaces into two lobes to be bent off after disengagement of jointed parts. Note here that one of said lobes is shorter.EFFECT: higher reliability of joint, lower labour input.3 cl, 2 dwg |
