FIELD: machine engineering.
SUBSTANCE: piece consists of a package of plates containing folds, with the formation of a sequence of positive and negative stops. Each stop contains ribs. Each of the ribs consists of at least one cut strip in one of the noted plates. The strip remains rigidly connected to the plate on at least one side, the strip being deformed to form an opening that forms a discontinuity on the surface of the plate and in which the stopping direction of one plate forms a non-zero angle with respect to the stop direction of the adjacent plate. Each plate comprises at least one longitudinal region parallel to one of the edges of the plate, in which the stops do not comprise a hole. The zones are arranged in such a way that the two adjacent plates have the noted zone located one above the other, forming at least one contact point between the positive stop and the negative stop of the two adjacent plates.
EFFECT: easy mounting of the piece, no piling.
