Invention relates to industry of building and mechanical engineering, especially to the production technologies of sheet-type multilayer ribbed plates. Offered method of production for ribbed plates is characterized by the following technological procedures: a) the provided load-bearing plates for forming ribs are glued to sheet(s) of foam-plastic or similar material from one or both sides; b) the previously glued structure is cut in strips at a predetermined angle with an longitudinal axis of said sheet providing the thickness of all strips equal to the distance between said covering layers of designed plate; c) the multilayer ribbed plate is created by orienting said strips transversally to the covering layers of plate and by gluing or fastening them mutually together, as well as with covering layers of plates. Besides, depending on conditions in executive process of operation c), said strips could be arranged in groups, which consist of previously set amounts of strips. The gaps with the certain width can be formed between strips in said groups, in which it is possible, e.g., to place latticed structure that provides additional system of ribs, or they even can be left empty in the process of forming the plate.
