- the invention relates to a self-supporting and load-transferring component and a method for producing the component according to the preambles of claims 1, 2, 3, 4, 5, 44, 45, 76, 84 and 32, 33 and the use of the component according to the claims
- DE 925 858 C2 discloses a carrier-shaped component which is equipped with one or more spacer elements which are offset in a wave-like manner from one another by half a wavelength or extend in phase and parallel and in parallel in the longitudinal direction of the component and in a direction transverse thereto, the ones consisting of non-form-glued Spacer elements made of plywood, in particular webs, engage in the recesses which are recessed in strip-shaped, in particular board-like or bar-shaped cover layers or with which the spacer elements are connected in a force-fitting and positive-locking manner.
- Such spacer elements made of plywood are spaced apart from one another and preferably connected to the cover layers in a force-fitting and form-fitting manner, as a result of which these wooden components have only a low load-bearing capacity in relation to transverse forces acting in the transverse direction.
- these wooden components have only a low load-bearing capacity in relation to transverse forces acting in the transverse direction.
- the cover layers formed from a square timber cross-section which is limited by the growth limits, the area of use of these components as a surface element is severely restricted and such components can only be loaded in the middle in order to prevent the risk of lateral tilting.
- EP 0 568 270 B1 discloses a component with cover layers that are kept spaced apart from one another by spacer elements, the spacer elements of which in the longitudinal extent of the
- Component form several separate cellular chambers or cavities.
- the spacer elements in particular webs, which touch at least in certain areas, are connected to the cover layers in the touching partial areas and on their narrow sides.
- the cellular chambers formed by the webs are filled with a filler and form a core that is between the first and the second Cover layer is arranged and connected to this.
- Such components made of wood have the disadvantage that the cover layers are supported only over part of their width by the spacer elements, as a result of which they have only a low load-bearing capacity, in particular in the edge zones of the narrow side flats, in particular in a plane perpendicular to their longitudinal extent , Furthermore, these components, which transmit essentially only very low loads, cannot be used as highly loadable primary support structures, which in turn leads to a very restricted area of use.
- document DE 195 21 027 AI discloses a component, in particular a double-T support, consisting of two cover layers spaced apart from one another by means of spacers, in particular webs, only one web running unevenly or undulating in the longitudinal extension of the component between the cover layers is arranged.

- Such designs of components made of wood have the disadvantage that the support elements connected in the longitudinal direction to form a surface element in the area of the joining surfaces are subjected to high shear stress and a gradation can occur between two interconnected cover layers. In order to create a large-area component, a large number of joining surfaces are therefore required, which can only be produced with a correspondingly high production outlay.
- the spacer elements are inserted and glued in recesses arranged recessed in the cover layers to enlarge the connecting areas between the spacer elements and the cover layers, for which purpose the thickness of the cover layers is at least reduced by not reducing the load-bearing capacity the depth of the recess must be made larger and the material requirement for the cover layers must be increased significantly as a result.
