The invention relates to a building board or structural unit, especially a structural, wall, paneling or support unit or the like with a multi-layer structure, preferably based on wood or wooden materials, which is formed with two cover layers that are spatially separated from each other and placed parallel to each other and at least one core layer placed between them and joined to them, characterized in that between two if necessary multilayer cover layers (3, 4) each with a planar layer material, preferably from the wood and wooden material group, as well additionally as metals, textile and fiber materials, cardboard, papers plastics, fiber-reinforced plastics, mineral-based construction materials and rock, an at least single-layer slanted-fiber core layer (5) is placed, which is formed from a material having unitary structuring, preferably formed from wood or wood plastic, whereby the fibers form an angle (+<img id="CUSTOM-CHARACTER-00001" he="3.13mm" wi="2.46mm" file="US20090307996A1-20091217-P00001.TIF" img-content="character" img-format="tif"/>) to the longitudinal direction of the two cover layers (3, 4) between +25 to 80° and/or an angle (-<img id="CUSTOM-CHARACTER-00002" he="3.13mm" wi="2.46mm" file="US20090307996A1-20091217-P00001.TIF" img-content="character" img-format="tif"/>) of -25 to -80°, and whereby additionally provision is made that the slanted-fiber core layer (5) have a multiplicity of these same positively-slanted and/or negatively-slanted slant cavities (6, 6') that fully run through, are aslant to the particular fiber direction, preferably of equal size to the other, and preferably uniformly distributed. Additionally it relates to a procedure for manufacturing and using the building boards. |
