ABSTRACT:
A method for the production of panel-type components having at least three layers of boards disposed parallel to the plane of the component, with the boards being connected to one another without glue by dowels extending substantially transversely to the plane of the component, includes disposing a plurality of layers of boards on top of each other in different orientations, providing a plurality of bores in these boards which penetrate the layers, and pressing dowels into the bores. An especially high strength is achieved by tensioning layers of the boards during drilling and insertion of the dowels, the tensioning including applying compressive forces. Also, the dowels are preferably compacted in a radial direction before insertion in the bores.
