Abstract

The rigidity of a flat sheet (1) of material such as metal, plastics or fibre reinforced plastics, is increased by forming rows of convex rectangular areas. These areas are so shaped that the abutting edges of the rectangles are curved in the plane perpendicular to the general plane of the sheet. The sheet then has a curved cross-section in both longitudinal and transverse directions. The resistance of the sheet to bending in any direction is thus considerably increased. USE - Light-weight rigid structures.

Description

Die Erfindung betrifft die versteifende Durchformung schicht­ förmiger Materialien, insbesondere für Metalle, Kunststoffe und vorwiegend zugfeste Mischwerkstoffe (Faserverbundstoffe).The invention relates to the stiffening forming layer shaped materials, especially for metals, plastics and mainly tensile mixed materials (fiber composites).

Durch die Ausformungen kann die gleiche Biegesteifigkeit in jeder Belastungsrichtung erreicht werden. Durch die versteifende Wirkung der Ausformungen kann eine höhere Festigkeit von Konstruk­ tionen aus diesen Platten und Formteilen erreicht werden. Dadurch kann eine Material- und Gewichtsersparnis erreicht werden.The same bending stiffness can be achieved by the formations can be reached in any direction. By stiffening The effect of the formations can increase the strength of the construct ions from these plates and molded parts can be achieved. Thereby material and weight savings can be achieved.

Wellblech z. B. erfüllt den Anspruch der Biegesteifigkeit nur in einer Richtung. Sickung und Kalottierung von Blech nutzen die Materialmöglichkeiten nur begrenzt. Diese Versteifungen wirken meistens nur in einer Hauptrichtung, so daß für jede Konstruktion besondere Sicken entworfen werden müssen. Für die Versteifung in jeder Beanspruchungsrichtung müssen mehrere Platten kombiniert werden oder die erreichte Steifigkeit, wie z. B. beim Kalotten­ blech aus rhombenförmig angeordneten Kugeloberflächenabschnitten erscheint im Verhältnis zur Schichthöhe zu gering.
(s. a. Merkblatt 350, Versteifung von Stahlblechteilen, Beratungs­ stelle für Metallverwendung, Düsseldorf, 1. Auflage 1971)Corrugated iron z. B. meets the requirement of bending stiffness in one direction only. Sealing and calotting of sheet metal use the material options only to a limited extent. These stiffeners usually only act in one main direction, so that special beads must be designed for each construction. For the stiffening in each direction of stress, several plates must be combined or the stiffness achieved, such as. B. in calotte sheet made of diamond-shaped spherical surface sections appears too low in relation to the layer height.
(see leaflet 350, stiffening of sheet steel parts, advice center for metal use, Düsseldorf, 1st edition 1971)

Der Erfindung liegt die Aufgabe zugrunde, mit einer Flächen­ verformung eine optimale Versteifung in jeder Beanspruchungs­ richtung zu erreichen. Die Aufgabe wird erfindungsmäßig dadurch gelöst, daß in sich steife konvexe Rundflächen, (Kugeloberflächen­ ausschnitten weitgehend ähnlich), durch ihre Anordnung nur ungerade, versteifende Kehlen bilden, so daß in jeder Schnittlinie des schichtförmigen Bauteils keine Knickgerade erscheint. Die Kugeloberflächenauschnitte mit im Mittel 90 Grad messendem Winkel bilden das Optimum der Versteifung sowohl für Torsions-, als auch Druck- und Zugbelastungen. The invention has for its object with a surface deformation an optimal stiffening in every load direction to reach. The task is inventively thereby solved that stiff convex round surfaces, (spherical surfaces cutouts largely similar), by their arrangement only form odd, stiffening throats so that in every cut line no kink line appears in the layered component. The Spherical surface cutouts with an angle measuring 90 degrees on average form the optimum of stiffening for both torsion and Pressure and tensile loads.  

Die gleichartige Verfaltung benachbarter Rundflächen kann die Schichthöhe des Bauteils verringern, ohne die statischen Eigenschaften zu verschlechtern. Die Faltensegmente bestehen dabei vorzugsweise aus zweiachsig gekrümmten Flächen. Die Falten bilden mit den Falten der benachbarten Fläche wieder versteifende Kanten bzw. Kehlen.The similar folding of neighboring round surfaces can reduce the layer height of the component without the static Deteriorate properties. The fold segments exist preferably from biaxially curved surfaces. The folds form stiffening with the folds of the adjacent surface Edges or throats.

Zur Herstellung von Mehrschichtenplatten und zur Verbindung mit anderen Bauteilen können die oberen und unteren Ausformungen der Schicht z. B. abgeplattet sein.For the production of multilayer boards and for connection with other components can have the upper and lower formations the layer z. B. be flattened.

Bei auf das Material abgestimmter Schichtdicke, Form und Zuschnitt der Rundformen wird eine optimale Biegesteifigkeit in jeder Belastungsrichtung erreicht, so daß sich eine Material- und Gewichtsersparnis ergibt.With the layer thickness, shape and cut matched to the material The round shapes will have optimal bending stiffness in each Load direction reached, so that a material and Weight saving results.
