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.
Claims11
A method for producing a panel-type component having at least three layers of boards disposed parallel to a plane of the component, with the boards of the at least three layers being connected to one another without glue by dowels which extend substantially transversely to the plane of the component, comprising the steps of:
- (a) placing at least three layers of boards on top of each other so that the boards in adjacent layers extend in different directions,
- (b) applying a compressive force to the at least three layers of board so that the at least three layers of boards are tensioned against each other,
- (c) drilling a plurality of bores through the boards of the at least three layers of boards of step (b),
- (d) providing a plurality of dowels which have been compacted in a radial direction, and
- (e) inserting the radially compacted dowels of step (d) into said bores while the boards of the at least three layers of boards are compressed so as to connect the boards of the at least three layers of boards together.
