Abstract
Aluminiumverbundplatte 2 mit einem Kern aus Aluminiumschaum 1 und außenseitig angebrachten beschichteten Aluminiumplatten 3, welche auf Grund der Schaumstruktur höhere Festigkeit und geringes Gewicht aufweist. Schutzhelmkonstruktion 6 bestehend aus geschäumtem Aluminium 1, welcher auf Grund der Schaumstruktur die aufprallenden Außenkräfte gut aufnehme kann und dadurch eine höhere Schutzfunktion ausweist. Dachziegelkonstruktion 10 bestehend aus einem Aluminiumschaum 1, welcher auf Grund der Schaumstruktur hohe Festigkeit und ein vergleichbar sehr geringeres Gewicht aufweist und die Geräuschentwicklung durch herunterfallenden Regen eindämmt. Die Dachziegelkonstruktionen 10 können miteinander durch elastische Klebung 8 verbunden werden und mittels Befestigung 9 mit der Dachkonstruktion verschraubt werden.Aluminum composite plate 2 with a core of aluminum foam 1 and externally mounted coated aluminum plates 3, which has higher strength and low weight due to the foam structure. Safety helmet construction 6 consisting of foamed aluminum 1, which due to the foam structure, the impacting external forces can absorb well and thus identifies a higher protective function. Roof tile construction 10 consisting of an aluminum foam 1, which due to the foam structure has high strength and a comparably very low weight and reduces the noise caused by falling rain. The tile constructions 10 can be connected to each other by elastic bonding 8 and bolted by means of fastening 9 with the roof construction.
Description
Aluminiumverbundplatten werden derzeit derart hergestellt, dass eine dünne innenliegende Aluminiumplatte und eine außenliegende Aluminiumplatte mit einem in der Regel Kunststoffkern angeordnet wird, welcher in der Regel aus Polyethylen oder einem schlecht entflammbaren Kunststoff besteht. Die Aluminiumplatten werden zuvor farblich beschichtet, so dass die Verbundplatte für verschiedene Art von Verkleidungen verwendet wird. Dabei handelt es sich um homogene feste Materialien, welche miteinander verbunden werden.Composite aluminum panels are currently manufactured by placing a thin, interior aluminum panel and an external aluminum panel with a generally plastic core, which is typically polyethylene or a poorly flammable plastic. The aluminum plates are previously coated in color, so that the composite panel is used for various types of panels. These are homogeneous solid materials which are joined together.
Der Nachteil dieser Konstruktion ist, dass für den Kunststoffkern sehr viel Material verwendet wird und der Verbund zwischen Aluminium und Kunststoff auf Grund von verschiedenen Wärmeausdehnungskoeffizienten hohen Belastungen ausgesetzt wird. Desweiteren sind diese derartigen Verbundplatten nur wenig resistent gegen mechanische Einwirkungen und benötigen zusätzlich für ihre Befestigung umfangreiche Unterkonstruktionen. Auch die Entsorgung der Platten bzw. das Recycling der Platten ist problematisch, weil die verschiedenen Rohstoffe aus welchen diese hergestellt sind nur schwer voneinander zu trennen sind.The disadvantage of this design is that a lot of material is used for the plastic core and the bond between aluminum and plastic is subjected to high loads due to different thermal expansion coefficients. Furthermore, these composite panels are only little resistant to mechanical effects and also require extensive substructures for their attachment. The disposal of the plates or the recycling of the plates is problematic because the different raw materials from which they are made are difficult to separate.
Die Außenhaut von Schutzhelmen wird derzeit aus Kunststoff und/oder Aluminium hergestellt, an welchen dann innenseitig eine Auskleidung befestigt wird, welche an die jeweilige Kopfgröße angepasst werden kann. Diese homogenen Kunststoff oder Aluminiumschichten nehmen mechanische Schläge auf, um zu verhindern, dass diese zu Verletzungen am Kopf führen.The outer skin of protective helmets is currently made of plastic and / or aluminum, to which then on the inside a liner is attached, which can be adapted to the respective head size. These homogeneous layers of plastic or aluminum absorb mechanical impacts to prevent them from causing head injuries.
Der Nachteil dieser Helmkonstruktion ist, dass die Kunststoffhelme auf Grund von Verlust von Weichmachern ihre ursprünglich notwendigen Qualitäten verlieren und verspröden, was letztlich zum Verlust der Schutzfunktion führt. Die Aluminiumhelme nehmen nur schlecht die mechanischen Schläge auf und führen diese weiter an den Kopf, was die Schutzfunktion erheblich verschlechtert.The disadvantage of this helmet construction is that the plastic helmets lose their original necessary qualities due to loss of plasticizers and embrittle, which ultimately leads to the loss of the protective function. The aluminum helmets take on the mechanical shocks bad and carry them to the head, which significantly worsens the protective function.
Dachziegeln für Gebäude werden aus gebrannten Ton, Beton und Aluminiumblech hergestellt. Der Nachteil der ersten beiden Ausführungen ist ein sehr hohes Gewicht, welches eine entsprechend stabile Unterkonstruktion des Daches benötigt. Dachziegel aus Beton werden oft porös, beherbergen sodann Samen von Pionierpflanzen und sind folglich einer raschen Beschädigung durch Regen und Frost ausgesetzt. Darüber hinaus sind diese oftmals mit Betonfarbe beschichtet, die Farben sind der UV-Strahlung und der Feuchtigkeit und Frost ausgesetzt und verlieren schnell ihre ursprünglichen Qualitäten, was letztlich zu einem ungünstigen Erscheinungsbild führt. Die „Aluminiumdachziegel” bestehend aus einer homogenen Aluminiumplatte, die verschiedenartig geformt ist und unterseitig mit Antidröhnmittel beschichtet werden muss, damit die Regentropfen schallmäßig abgedämmt werden, damit es nicht zu starker Geräuschentwicklung während dem Regen kommt.Roof tiles for buildings are made of baked clay, concrete and aluminum sheet. The disadvantage of the first two versions is a very high weight, which requires a correspondingly stable substructure of the roof. Concrete roof tiles often become porous, then harbor seeds of pioneer plants and are therefore exposed to rapid damage from rain and frost. In addition, these are often coated with concrete paint, the colors are exposed to UV radiation and moisture and frost and quickly lose their original qualities, which ultimately leads to an unfavorable appearance. The "aluminum roof tile" consists of a homogeneous aluminum plate, which is shaped differently and must be coated on the underside with anti-noise agent, so that the raindrops are soundproofed, so it does not cause excessive noise during the rain.
Die nachstehend beschriebene Erfindung soll die vorgenannten Nachteile der beschriebenen Gegenstände beheben. Die
