Leichtbaustrukturen sind bereits seit langem bekannt. Der Hauptgrund für den Einsatz von Leichtbaustrukturen ist die Gewichtsreduktion. Daher finden Leichtbaustrukturen beispielsweise Anwendung im Flugzeugbau, in der Automobilindustrie und in der Bauindustrie, insbesondere beim Bau von Gebäuden.The invention relates to a lightweight structure with at least one structural unit, which is composed of a plurality of mutually connected to a framework supporting rods, wherein the support rods are continuously connected to each other, wherein the structural unit has an upper and lower cover plate, between which the framework of support rods is arranged. Lightweight structures have been known for a long time. The main reason for the use of lightweight structures is the weight reduction. For this reason, lightweight structures are used, for example, in aircraft construction, in the automotive industry and in the construction industry, in particular in the construction of buildings.
Leichtbaustrukturen können auf unterschiedliche Arten gebildet werden. Es ist möglich, dass Leichtbaumaterial eingesetzt wird, d.h. die Leichtbaustruktur und die Gewichtsersparnis resultieren aus den Materialeigenschaften.Lightweight structures can be formed in different ways. It is possible that lightweight material is used, i. the lightweight structure and the weight savings result from the material properties.
Ein anderer Ansatz ist, die Leichtbaustruktur dadurch zu bilden, dass herkömmlich verwendetes Material mit Material-Ausmagerungen versehen wird, so dass das durch die Material-Ausmagerungen eingesparte Material eine Gewichtsreduktion ergibt.Another approach is to form the lightweight structure by providing material that has conventionally been used with material outgrowths so that the material saved by the material disbursements results in a weight reduction.
Schließlich ist noch ein weiterer Ansatz denkbar, nämlich dass die Leichtbaustruktur aus miteinander zu einem Fachwerk verbundenen Stützstäben ausgebildet ist.Finally, a further approach is conceivable, namely that the lightweight structure is formed from mutually connected to a truss supporting rods.
Allen Leichtbaustrukturen ist jedoch gemeinsam, dass die Gewichtsreduktion nicht zu Lasten der Stabilität des gesamten Systems gehen darf.However, all lightweight structures have in common that the weight reduction must not be at the expense of the stability of the entire system.
Bei der Ausgestaltung der Leichtbaustruktur als Fachwerk besteht der Bedarf, eine Fachwerkstruktur bereitzustellen, die in Abhängigkeit vom Anwendungsfall hinreichende Stabilität und Steifigkeit aufweist.In the design of the lightweight structure as a framework, there is a need to provide a framework structure, which has sufficient stability and rigidity depending on the application.
Die
Diese Aufgabe wird durch eine Leichtbaustruktur mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen dargestellt.This object is achieved by a lightweight structure having the features of independent claim 1. Further developments of the invention are shown in the subclaims.
Ein Aspekt ist, dass die Stützstäbe stetig ineinander übergehen. Dadurch werden im Lastfall auftretende Spannungsspitzen vermieden, die im schlimmsten Fall zu Bauteilversagen führen können. Das Fachwerk aus Stützstäben ist kraftflussoptimiert, so dass es in der Lage ist, unterschiedliche Arten von Beanspruchungen aufzunehmen. Hierzu zählen insbesondere Zug- und Druckkräfte, Scherkräfte sowie Torsionskräfte. Die Leichtbaustruktur der Erfindung weist eine weitere Optimierung des Übergangs zwischen den Stützstäben auf, die durch einen krümmungsstetigen Übergang, der auch als C2-Stetigkeit bezeichnet wird, erzielt wird. In diesem Fall gehen die Stützstäbe fließend ineinander über.One aspect is that the support rods are continuously merging. This avoids voltage peaks occurring in the event of a load, which in the worst case can lead to component failure. The framework of support rods is power flow optimized so that it is capable of different types of stresses take. These include in particular tensile and compressive forces, shear forces and torsional forces. The lightweight construction of the invention has a further optimization of the transition between the support rods, which is achieved by a curvature continuous transition, which is also referred to as C2 continuity. In this case, the support rods are flowing into each other.
Bei einer Weiterbildung der Erfindung sind die Stützstäbe untereinander zu Stützstrukturen verbunden, die durch modulare Addition zu einem Raumfachwerk kombiniert sind. Die Stützstrukturen können beispielsweise aus mehreren aneinandergereihten Stützstäben gebildete, räumliche Stützstab-Ketten sein, die durch geeignete Aussteifungen in sich stabil sind. In besonders bevorzugter Weise sind die Stützstrukturen jedoch als Stützpolygone ausgebildet. Als Stützpolygone eignen sich hier besonders Stützdreiecke, jedoch auch Stützhexagone. In besonders bevorzugter Weise sind mehrere Stützpolygone zu Stützpolyedern kombiniert.In a further development of the invention, the support rods are interconnected to support structures, which are combined by modular addition to a space framework. The support structures may be, for example, formed from a plurality of juxtaposed support rods, spatial support rod chains, which are stable by suitable stiffeners in itself. In a particularly preferred manner, however, the support structures are formed as Stützpolygone. As Stützpolygone are particularly support triangles, but also Stützhexagone. Most preferably, several support polygons are combined to support polyhedra.
In besonders bevorzugter Weise sind die Stützstrukturen als Fraktale ausgebildet. In diesem Fall besitzen also innerhalb einer Struktureinheit sämtliche Stützstrukturen dieselbe Form und unterscheiden sich lediglich in der Dimensionierung. Insbesondere kann die Struktureinheit selber insgesamt als Stützpolyeder ausgebildet sein, die aus mehreren Strukturebenen von Stützpolyedern gleicher Form aufgebaut ist.In a particularly preferred manner, the support structures are formed as fractals. In this case, therefore, all the support structures within a structural unit have the same shape and differ only in dimensioning. In particular, the structural unit itself may be designed overall as a support polyhedron, which is constructed from a plurality of structural planes of supporting polyhedra of the same shape.
Bei einer Weiterbildung der Erfindung sind die Stützpolyeder als platonische Körper ausgebildet. Die Stützpolyeder können also als Tetraeder, Hexaeder, Oktaeder, Dodekaeder oder Ikosaeder ausgebildet sein.In a development of the invention, the supporting polyhedra are designed as platonic bodies. The supporting polyhedra can therefore be formed as tetrahedron, hexahedron, octahedron, dodecahedron or icosahedron.
Es ist auch möglich, dass die Stützpolyeder als archimedische Körper ausgebildet sind. Die Stützpolyeder können also beispielsweise als Tetraederstumpf, Kuboktaeder, Hexaederstumpf, Oktaederstumpf, Rhombenkuboktaeder, Ikosidodekaeder oder dergleichen ausgebildet sein.It is also possible that the support polyhedra are designed as Archimedean body. The supporting polyhedra can thus be formed, for example, as a tetrahedral stump, cuboctahedron, hexagonal stump, octahedral stump, rhombic cuboctahedron, icosidodecahedron or the like.
Bei einer Weiterbildung der Erfindung weist die Struktureinheit eine obere und untere Deckplatte auf, zwischen denen das Fachwerk aus Stützstäben angeordnet ist. Insbesondere bei offenen Stützstab-Ketten dienen die Deckplatten als stabilisierende Bauteilkomponenten, die für die Steifigkeit des Systems von Vorteil sind.In a further development of the invention, the structural unit has an upper and lower cover plate, between which the framework is arranged from support rods. Particularly in the case of open support rod chains, the cover plates serve as stabilizing component parts which are advantageous for the rigidity of the system.
Die Struktureinheit kann wenigstens einen aus Stützstäben gebildeten Ringanker aufweisen. Ein solcher Ringanker dient vor allem zur Ableitung von Torsionskräften im Belastungsfall.The structural unit may comprise at least one ring anchor formed from support rods. Such a ring anchor is used primarily for the derivation of torsional forces under load.
Es ist möglich, dass die Struktureinheit eine hexagonale Außenkontur aufweist. Es sind jedoch auch andere Außenkonturen denkbar.It is possible that the structural unit has a hexagonal outer contour. However, other outer contours are conceivable.
In besonders bevorzugter Weise sind mehrere Struktureinheiten zu einem Struktureinheit-Cluster verbunden.In a particularly preferred manner, a plurality of structural units are connected to form a structural unit cluster.
Es ist möglich, dass die Stützstäbe in variierenden Winkeln miteinander verbunden sind. Diese hängen von der Bauhöhe ab.It is possible that the support rods are connected at varying angles. These depend on the height.
Bei einer Weiterbildung der Erfindung weisen die Stützstäbe innerhalb einer Struktureinheit eine Gitterform auf, die als hexagonal dichte Packung ausgebildet ist. Falls dann die Struktureinheit zusätzlich noch eine hexagonale Außenkontur aufweist, ist ein aus solchen Struktureinheiten gebildetes Struktureinheit-Cluster besonders dicht gepackt.In a further development of the invention, the support rods within a structural unit on a grid shape, which is formed as a hexagonal dense packing.

Bei einer Weiterbildung der Erfindung sind an Verbindungsstellen zwischen jeweils zwei benachbarten Stützstäben kugelähnliche Knoten ausgebildet.In a further development of the invention, ball-like nodes are formed at connection points between in each case two adjacent support rods.
Die Erfindung betrifft ferner noch die Verwendung einer Leichtbaustruktur gemäß einem der Ansprüche 1 bis 16 als Fachwerkstruktur, insbesondere Fachwerkträger.The invention further relates to the use of a lightweight structure according to one of claims 1 to 16 as a framework structure, in particular trusses.

Die vorstehend beschriebenen technischen Beispiele einer Leichtbaustruktur 11 haben gemeinsam, dass benachbarte Stützstäbe 13 tangentenstetig miteinander verbunden sind. Daher sind diese Beispiele nicht Teil der Erfindung. Demgegenüber wird bei einer erfindungsgemäßen Leichtbaustruktur eine weitere Optimierung durch krümmungsstetige Übergänge zwischen den Stützstäben 13 erzielt, wodurch eine weitere Kerbspannungsoptimierung erzielt wird.The above-described technical examples of a
Die erfindungsgemäße Leichtbaustruktur ist geeignet im Belastungsfall Zug-, Druck, Scher- und Torsionskräfte aufzunehmen und optimal abzuleiten.The lightweight structure according to the invention is suitable in the load case to absorb tensile and compressive, shear and torsional forces and optimally dissipate.
