Description

Die Erfindung betrifft eine Mehrschichtenleichtbauplatte aus beidseitigen ebenen oder profilierten Metallaußenlagen und dazu eingebrachtem Kunststoffhartschaum, der die Metallaußenlagen auf Abstand hält, sowie eine Vorrichtung zu ihrer Herstellung.The invention relates to a multilayer lightweight building board made of flat or profiled metal outer layers on both sides and a plastic rigid foam that keeps the outer metal layers at a distance, as well as a device for their manufacture.

Für den Einsatz als Dach- oder Wandbauteile sind Leichtbauplatten bekannt (z. B. DE-GM 66 03 042 und 73 03 804), bei denen zwischen vorzugsweise metallischen, sich über die gesamte Breite erstreckenden Deckschichten eine Schaumstoffschicht angeordnet ist. Bei dieser Art von Bauteilen wird die Sandwichwirkung statisch genutzt. Die ebenen oder profilierten Deckschichten bilden auch die endgültige, sichtbare Oberfläche. Lightweight panels are known for use as roof or wall components (e.g. DE-GM 66 03 042 and 73 03 804), in which between preferably metallic, extending over the entire width Cover layers a foam layer is arranged. With this type of component, the sandwich effect used statically. The flat or profiled top layers also form the final, visible surface.

Derartige Bauteile können nur schwierig mit anderen Bauteilen bzw. Baustoffen verbunden, insbesondere verkleidet werden.Such components can only be connected with other components or building materials with difficulty, in particular to be disguised.

Es sind auch Leichtbauplatten bekannt, bei denen in den auf ein Profilblech aufgetragenen Kunststoffhartschaum Holzplatten eingelegt sind. Dabei ist jedoch eine Sandwichwirkung statisch nicht nutzbar zu machen, da die Holzlattung innerhalb der jeweiligen Plattenlänge Stöße aufweist. Weiterhin wird insbesondere als verbesserungsbedürftig angesehen, daß eine kontinuierliche Herstellung durch die in der Länge begrenzten Holzlatten nicht möglich ist.There are also known lightweight panels in which the rigid plastic foam applied to a profiled sheet metal Wooden panels are inserted. However, a sandwich effect cannot be used statically, because the wooden battens have joints within the respective panel length. Furthermore, it is particularly considered to be in need of improvement considered that a continuous production by the limited in length Wooden slats is not possible.

Der Erfindung liegt die Aufgabe zugrunde, eine Mehrschichtenleichtbauplatte der eingangs genannten Art zu schaffen, bei der mit einfachen Mitteln andere Bauteile, insbesondere Verkleidungen angebracht werden können.The invention is based on the object of providing a multilayer lightweight building board of the type mentioned at the beginning To create a way in which other components, in particular cladding, are attached using simple means can.

Gemäß der Erfindung wird dazu vorgeschlagen, daß eine Metallaußenlage aus einzelnen, im seitlichen Abstand zueinander angeordneten endlosen Metallprofilen bestehtAccording to the invention, it is proposed that a metal outer layer from individual, at a lateral distance there is endless metal profiles arranged to one another

Bei einem Dachelement (DE-OS 25 08 04S) sind an der Innenseite beider Abdeckbieche im seitlichen Abstand zueinander Metallwiiikel fest ajigeocdnet. Dadurch soll die Schubkraftübertragung zwischen Schaum und sich über die gesamte Breite erstreckenden Abdeckblechen verbessert werden. Das nicht kontinuierlieh gefertigte Dachelement ist nicht zur Aufnahme von Verkleidungen vorgesehen, sondern stellt bereits selbst eine fertige Verkleidung, z. B. den Deckenabschluß, dar.In a roof element (DE-OS 25 08 04S) are on the inside of both cover sheets at a lateral distance metal objects firmly attached to each other. Through this is intended to transfer the shear force between the foam and the cover plates extending over the entire width be improved. The roof element, which is not manufactured continuously, is not intended to accommodate Cladding provided, but is already a finished cladding, z. B. the ceiling finish.

Dagegen wird durch die erfindungsgemäße Lösung auf ein über die gesamte Breite durchgehendes Abdeckblech verzichtet. Die Abdeckung des Schaumkerns und seine Sicherung gegen Wasseraufnahme erfolgt lediglich durch eine als Wasserdampf-Diffusions-Dichtung wirksame Folie von maximal ca. 50 μπι.In contrast, the solution according to the invention provides for a cover plate that is continuous over the entire width waived. The foam core is only covered and secured against water absorption by a film effective as a water vapor diffusion seal of a maximum of approx. 50 μm.

Dadurch wird erfindungsgemäß in einfacher Weise und unter wesentlicher Einsparung von Material und Gewicht eine sichere Befestigungsmöglichkeit für andere Bauteile erzielt.This is according to the invention in a simple manner and with substantial savings in material and Weight achieved a secure attachment option for other components.

In weiterer Ausgestaltung des Erfindungsgedankens können vorteilhaft die Metallprofile über die Oberflächenebsne des Kunststoffhartschaums hinausragen, so daß ohne weiteres ein Abstand, z. B. für Hinterlüftungszwecke, entsteht.In a further embodiment of the inventive concept, the metal profiles can advantageously be placed over the surface plane of the rigid plastic foam protrude, so that easily a distance, z. B. for ventilation purposes, arises.

Es können aber auch in besonderen Fällen die Metallprofile nichi über die Oberflächenebene hinausragen.
Die erfindungsgemäße Mehrschichtenleichtbauplatte kann, wie bei Sandwichprodukten bekannt, als selbsttragendes Dach- oder Wandbauteil eingesetzt werden, wobei z. B. Fassadenbaustoffe oder Dacheindeckungen ohne weiteres auch mit der notwendigen Hinterlüftung montiert werden können. Durch die ermöglichte kontinuierliche Herstellung können alle gewünschten Plattenlängen ohne Stoßverbindungen der Metallprofile gefertigt werden.In special cases, however, the metal profiles cannot protrude beyond the surface plane.
The multilayer lightweight construction panel according to the invention can, as is known in sandwich products, be used as a self-supporting roof or wall component, with z. B. facade building materials or roof coverings can easily be installed with the necessary rear ventilation. Thanks to the continuous production that is made possible, all desired panel lengths can be produced without butt joints between the metal profiles.

Die Befestigung an den Metallprofilen durch gezielte Auswahl der Befestigungsmittel und vorgegebene Anzugskräfte ergibt absolut nachweisbare Befestigungskräfte. Die Verwendung korrosionsbeständiger Materialien gewährleistet eine lange Haltbarkeit.Fastening to the metal profiles through the targeted selection of fasteners and specified tightening forces results in absolutely verifiable fastening forces. The use of corrosion-resistant materials ensures a long shelf life.

Die erfindungsgemäße Vorrichtung zur Herstellung der vorgeschlagenen Leichtbauplatte zeichnet sich vorteilhaft dadurch aus, daß für jedes Metallprofil ein Profilierwalzensatz quer zur Produktionseinrichtung verschiebbarangeordnet ist.The device according to the invention for producing the proposed lightweight construction panel is advantageous characterized in that for each metal profile a set of profiling rollers is arranged to be displaceable transversely to the production facility is.

Zweckmäßigerweise sind die Profilierwalzensätze auf Schiebwellen angeordnet, und das eine Plattenband weist zur Führung der Metallprofile und zur Kalibrierung der Zwischenräume Gummibänder auf.The profiling roller sets are expediently arranged on sliding shafts, and the one apron conveyor has rubber bands to guide the metal profiles and to calibrate the gaps.

Nachstehend wird die Erfindung anhand von in den Zeichnungen schematisch dargestellten Ausführungsbeispielen näher erläutert. Im einzelnen zeigtThe invention is described below with reference to the exemplary embodiments shown schematically in the drawings explained in more detail. In detail shows
