Self-and load-supporting component
First Claim
1. Self-supporting and load-transferring construction element with at least one cover layer, on which preferably several strip-shaped spacing elements are positioned, distributed across an inner facing surface of the cover layer, and, in the longitudinal extension, the spacing elements are joined by their joining surfaces directed towards the facing surface, in at least certain regions, to the facing surface of the cover layer in a non-positive and/or a positive join by means of a curable joining and/or fixing means, characterised in that the cover layer (7) and/or the spacing elements (18) are made from randomly oriented wood or wood material elements (73) joined by a binder, in particular wood chips and/or wood-type fibre materials, with cavities (75) and pores (74) in at least certain regions between the wood or wood material elements (73), and at least a main dimension (79) of the wood or wood material elements (73) of the cover layer (7) is bigger, by a multiple, in the region of the joining surfaces (16a, 16b) than a thickness (27) of the spacing elements (18), and/or the joining surfaces (16b) of the spacing elements (18) and the inner facing surface (15a) of the cover layer (7) sit in a butting arrangement with one another and are joined to one another by nothing more than the joining and/or fixing means (70).

Abstract
The invention relates to a self-supporting and load-transferring construction element (1) with at least one, preferably two cover layers (7), on which preferably several strip-shaped spacing elements (18) are placed, distributed on an inner facing surface (15a) of the cover layer (7), which are joined to the cover layer (7) in a non-positive and/or a positive join by means of a curable joining and/or fixing means (70). The cover layer (7) and/or the spacing elements (18) are made from randomly oriented wood or wood material elements (73) joined by a binder with cavities (75) and pores (74) disposed in between them. Disposed in a joining region (71) between the cover layer (7) and the spacing elements (18) is a joining and/or fixing zone (80) comprising cured joining and/or fixing means (70) and wood or wood material elements (73) and/or pores (74) and/or cavities (75), which has a higher mechanical strength than regions of the cover layer (7) and/or spacing elements (18) adjoining the joining and/or fixing zone (80).

45. Self-supporting and load-transferring construction element with two cover layers, joined to one another in a non-positive and/or positive join by means of several spacing elements distributed across the facing surfaces of the cover layers directed towards one another, characterised in that a core layer (11) consists of strip-shaped and non-flat spacing elements (18) and constitutes between 50% and 98% of the volume of the construction element (1) and the spacing elements (18) distributed over the facing surface (15) of the cover layer (7) accounts for between 10% and 50% of the material volume of the construction element (1), and narrow end faces (28) of the spacing elements (18) are aligned substantially parallel with the facing surface (15) of the cover layers (7).
