Description

Gesperrte Holzplatten erhalten zur Erzielung einer großen Biegefestigkeit eine Zwischenlage, die in der Regel aus gehobelten und verleimten Weichholzstäben besteht. Die Erfindung bringt nun ein Gitter als Zwischenlage `solcher Platten, das bei großer Material- und Arbeitsersparnis trotz leichter Biegsamkeit und geringer Eigenfestigkeit durch feste Verbindung mit zwei dünnen Platten eine starke Platte von hoher Druck- und Biegefestigkeit ergibt.Locked wooden panels are given to achieve great flexural strength an intermediate layer, usually made of planed and glued softwood rods consists. The invention now brings a grid as an intermediate layer `` such plates, that with great material and labor savings despite being slightly flexible and less Intrinsic strength through a firm connection with two thin plates a strong plate of high compressive and flexural strength.

Fig. i zeigt einen Schnitt A-B; Fig. 2 zeigt das Gitter im Grundriß ; Fig. 3 zeigt einen Schnitt C-D; in Fig.4 ist eine druck- und biegungsfeste Platte mit diesem Gitter perspektivisch dargestellt. Erfindungsgemäß wird eine dünne Platte, wie in Fig. i bis 3 dargestellt, gewellt, dann werden die Wellen von oben und von unten abwechslungsweise in Richtung A-B eingeschnitten, aber so, daß in den Wellensohlen (Punkt i) und in den Wellenscheiteln (Punkt 2) der Zusammenhang des Materials gewahrt bleibt. Wird nun die gewellte und geschnittene Platte in Richtung C-D gezogen und zur Wahrung der Form gepreßt, so entsteht ein gestelztes Bautengitter, dessen Kreuzungsstellen in Schrägrichtung die Außenschichten abwechselnd berühren. Dieses räumliche Gitter ist für sich leicht biegsam und hat eine ganz geringe Eigenfestigkeit.Fig. I shows a section A-B; Fig. 2 shows the grid in plan ; Fig. 3 shows a section C-D; in Fig.4 is a pressure and bending resistant plate shown in perspective with this grid. According to the invention a thin plate, as shown in Fig. i to 3, wavy, then the waves from above and from cut alternately in the direction A-B below, but so that in the corrugated soles (Point i) and in the wave crests (Point 2) the context of the material is preserved remain. The corrugated and cut plate is now pulled in the direction of C-D and Pressed to preserve the form, a stilted building lattice is created, its intersection points alternately touch the outer layers in the diagonal direction. This spatial grid is slightly flexible on its own and has a very low inherent strength.

Erfindungsgemäß wird dieses biegsame schwache Gitter in bekannter Weise zwischen zwei dünnen Platten fest mit diesen verbunden, wodurch eine starke druck- und biegungsfeste Platte entsteht.According to the invention, this flexible weak grid is known in Way between two thin plates firmly connected to these, creating a strong one Pressure and bending resistant plate is created.

Bei der Herstellung biegungsfester Sperrholzplatten beispielsweise bringt dieses Gitter gegenüber der seitherigen festen Zwischenlage bedeutende Vorteile, so ermöglicht es die Herstellung einer völlig spannungsfreien Platte. Das Gitter bringt große Materialersparnis, ist leichter und billiger und erfordert bei nahezu gleicher Druck- und Biegefestigkeit nur geringen Zeitaufwand für die Fertigstellung der festen Platte. Der besondere Vorteil gegenüber der seitherigen Herstellungsweise ergibt sich aber bei der Anfertigung gebogener, gewellter oder verwundener biegungsfester Platten, die bei Verwendung eines solchen Gitters ohne besondere Anpassungsarbeit in gleicher Weise wie eine ebene Platte gefertigt werden können.For example, in the manufacture of rigid plywood panels this grid brings significant advantages compared to the previous fixed intermediate layer, thus it enables the manufacture of a completely tension-free plate. The grid brings great material savings, is lighter and cheaper and requires almost same compressive and flexural strength only a small amount of time required for completion the fixed plate. The particular advantage over the previous production method but results in the manufacture of curved, corrugated or twisted more resistant to bending Plates that when using such a grid without any special adjustment work can be manufactured in the same way as a flat plate.

Das Gitter kann auch anstatt aus Holz in derselben Weise aus Stahl oder einem anderen geeigneten Metall, z. 13. Leichtmetall, hergestellt, aber auch aus Kunststoff gepreßt werden. Das Gitter kann auch an Stelle aus einer Platte aus einzelnen Stäben hergestellt werden, wobei in den Punkten i und 2 zweckmäßig Verbindungsstücke verwendet werden. Bei Metall kann die Herstellung des Gitters auch aus gebogenen Bändern oder Drähten erfolgen, die wieder bei den Punkten i und 2 fest miteinander verbunden werden.The grid can also be made of steel instead of wood in the same way or another suitable metal, e.g. 13. Light alloy, manufactured, but also be pressed from plastic. The grid can also be made from a plate in place individual rods can be produced, in points i and 2 expediently connecting pieces be used. In the case of metal, the production of the grille can also be made from curved Ribbons or wires are made, which again at points i and 2 firmly together get connected.
