Description

Die Erfindung betrifft ein plattenförmiges Bauelement mit einer starren Unterschale mit etwa der Stärke des Bauelements entsprechenden Randprofilen, mit einer biegsamen, mit den Randprofilen der Unterschale verbundenen Deckschicht und mit einem den Zwischenraum zwischen Unterschale und Deckschicht ausfüllenden Stützkern aus geschäumtem Isoliermaterial.The invention relates to a plate-shaped component with a rigid lower shell with edge profiles corresponding approximately to the thickness of the component, with a flexible cover layer connected to the edge profiles of the lower shell and with a support core made of foamed insulating material filling the space between the lower shell and cover layer.

Derartige plattenförmige Bauelemente sind in einer Vielzahl von Ausführungen bekannt. Siw werden in unterschiedlichsten Abmessungen und Breiten hergestellt und auf sehr verschiedene Weise entweder an Tragkonstruktionen befestigt oder als selbsttragende Bauelemente angeordnet.Such plate-shaped components are known in a variety of designs. Siw are manufactured in a wide variety of dimensions and widths and are either attached to supporting structures or arranged as self-supporting components in very different ways.

Bei den bekannten Bauelementen bereitet es einerseits Schwierigkeiten, insbesondere ihre starre Unterschale mit einer größeren Breite herzustellen, um auch großflächige Bau­elemente zu erhalten. Andererseits entstehen Probleme, wenn besonders breite und damit großflächige Bauelemente an einer Unterkonstruktion befestigt bzw. als selbsttragendes Bau­element sicher gehalten werden sollen. In diesen Fällen ist es häufig üblich, in der Mitte der Bauelemente Haltevorrich­tungen anzuordnen, die durch das Bauelement hindurch mittels Schrauben, Haken oder Nieten mit dem Bauelement verbunden werden. Diese das Bauelement durchdringenden Befestigungs­elemente stellen nicht nur eine unerwünschte Kältebrücke durch das ansonsten gut isolierende Bauelement dar, sondern haben häufig Undichtigkeiten zur Folge, da die das Bauelement insgesamt durchdringenden Öffnungen für die Befestigungs­elemente insbesondere bei der unvermeidbaren unterschied­ lichen Wärmeausdehnung nicht dauerhaft zuverlässig abge­dichtet werden können.In the known components, on the one hand, it is difficult to manufacture, in particular, their rigid lower shell with a larger width, in order to also obtain large-area components. On the other hand, problems arise when particularly wide and thus large-area components are to be attached to a substructure or are to be held securely as a self-supporting component. In these cases, it is often customary to arrange holding devices in the middle of the components, which are connected to the component through the component by means of screws, hooks or rivets. These fastening elements penetrating the component not only represent an undesirable cold bridge through the otherwise well-insulating component, but also frequently result in leaks, since the openings for the fastening elements penetrating the component as a whole, in particular in the case of the unavoidable difference thermal expansion cannot be reliably sealed in the long term.

Der Erfindung liegt die Aufgabe zugrunde, ein möglichst breites plattenförmiges Bauelement der eingangs beschriebenen Art zu schaffen, das einerseits eine einfache und damit preisgünstige Herstellung ermöglicht und andererseits die Möglichkeit einer zusätzlichen Befestigung in seiner Mitte gestattet, ohne daß diese Mittenbefestigung Probleme hin­sichtlich der Dichtigkeit des Bauelements zur Folge hat.The invention has for its object to provide the widest possible plate-shaped component of the type described above, which on the one hand allows simple and therefore inexpensive manufacture and on the other hand allows the possibility of additional attachment in the middle without this center attachment problems with regard to the tightness of the component has the consequence.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß die Unterschale in zwei zuein­ander getrennte Schalenhälften geteilt ist, die in der Längs­mitte des Bauelements jeweils mit einem aneinanderliegenden Randprofil ausgebildet sind, daß die Schalenhälften an ihren aneinanderliegenden Randprofilen mittels eines biegsamen Dichtungsstreifens miteinander verbunden sind, daß die bieg­same Deckschicht über die gesamte, durch beide Schalenhälften gebildete Breite des Bauelements verläuft und daß die Schalenhälften um die durch den Dichtungsstreifen und die Deckschicht gebildete Scharnierachse zwischen einer ge­streckten Lage und einer um 180° geschwenkten Lage faltbar sind, in der die Deckschichten der beiden Schalenhälften auf­einanderliegen.The solution to this problem by the invention is characterized in that the lower shell is divided into two separate shell halves, each of which is formed with an adjacent edge profile in the longitudinal center of the component, that the shell halves are connected to one another by a flexible sealing strip at their adjacent edge profiles that the flexible cover layer extends over the entire width of the component formed by both shell halves and that the shell halves can be folded between an extended position and a position pivoted by 180 ° around the hinge axis formed by the sealing strip and the cover layer, in which the cover layers of the the two shell halves lie on top of each other.

Durch die erfindungsgemäße Ausbildung des plattenförmigen Bauelements wird der Vorteil erreicht, daß bei vorgegebener Breite für die Unterschale ein Bauelement mit doppelter Breite entsteht. Auch bei einer vorgegebenen Transportbreite können Bauelemente transportiert werden, die im Einbauzustand die doppelte Breite aufweisen. Während der Lagerung und beim Transport der erfindungsgemäßen Bauelemente wird die biegsame Deckschicht zuverlässig gegen Beschädigungen geschützt, weil das Bauelement in zusammengefaltetem Zustand transportiert und gelagert wird. Auch bei Montagebeginn liegen die beiden Deckschichten aufeinander, so daß auch insoweit die Gefahr von Beschädigungen erheblich reduziert wird.The inventive design of the plate-shaped component achieves the advantage that a component with a double width is produced for the lower shell for a predetermined width. Even with a given transport width, components can be transported that are twice the width when installed. The flexible cover layer is reliably protected against damage during storage and transport of the components according to the invention because the component is transported and stored in the folded state. Even at the start of installation, the two cover layers lie on top of one another, so that the risk of damage is also considerably reduced.

Ein weiterer Vorteil des erfindungsgemäßen Bauelements ist darin zu sehen, daß dieses an den in der Längsmitte ver­laufenden, nebeneinanderliegenden Randprofilen der beiden Unterschalen ohne Schwierigkeit zusätzlich befestigt bzw. verankert werden kann, ohne daß die Befestigungselemente hierbei das Bauelement und insbesondere die Deckschicht durchdringen. Insgesamt ergibt sich somit ein Bauelement, das bei gleichem Abstand der Befestigungselemente eine doppelte Baubreite hat und demgemäß die Anzahl der Fugen und Über­lappungsbereiche auf die Hälfte reduziert.Another advantage of the component according to the invention can be seen in the fact that it can be additionally attached or anchored to the adjacent side profiles of the two lower shells running in the longitudinal center without difficulty, without the fastening elements penetrating the component and in particular the cover layer. Overall, this results in a component that has a double overall width with the same spacing of the fastening elements and accordingly reduces the number of joints and overlapping areas by half.

Bei einer Weiterbildung der Erfindung ist die biegsame Deck­schicht mindestens an einer Längsseite mit einem über das Randprofil der Unterschale überstehenden Randstreifen zur Überdeckung des beim Zusammenbau benachbarter Bauelemente entstehenden Stoßes ausgebildet. Hierdurch wird sicherge­stellt, daß auch zwischen benachbarten Bauelementen ent­stehende Stoßfugen zuverlässig abgedichtet werden.In a further development of the invention, the flexible cover layer is formed at least on one long side with an edge strip projecting beyond the edge profile of the lower shell to cover the joint which occurs when adjacent components are assembled. This ensures that butt joints created between adjacent components are reliably sealed.

Gemäß einem weiteren Merkmal der Erfindung wird der Dich­tungsstreifen im Bereich der nebeneinanderliegenden Rand­profile der Schalenhälften durch das geschäumte Isolier­material des Stützkerns gehalten. Damit wird das Entstehen von Kältebrücken verhindert.According to a further feature of the invention, the sealing strip is held in the region of the adjacent edge profiles of the shell halves by the foamed insulating material of the support core. This prevents the formation of cold bridges.

Die beiden in der Mitte des Bauelements nebeneinanderliegen­den Randprofile bilden bei einer erfindungsgemäßen Weiterbil­dung in der gestreckten Lage der Schalenhälften eine Aus­sparung, in die ein formschlüssig eingreifendes Befestigungs­ element einsetzbar ist. Durch diese Ausgestaltung wird ver­mieden, daß das erfindungsgemäße Bauelement mit Öffnungen, Aussparungen oder ähnlichen Maßnahmen versehen werden muß, um in seiner Mitte befestigt bzw. gehaltert zu werden.In a further development according to the invention, the two edge profiles lying next to one another in the middle of the component form a recess in the extended position of the shell halves, into which a form-fitting fastening engages element can be used. This configuration avoids that the component according to the invention has to be provided with openings, cutouts or similar measures in order to be fastened or held in its center.

Die beiden am Rand des Bauelements liegenden Randprofile der Schalenhälften sind vorzugsweise mit einem korrespondieren­den, beim Zusammenbau zweier Bauelemente formschlüssig inein­andergreifenden Profil ausgebildet, so daß sich auf einfache Weise eine zuverlässige Verbindung benachbarter Bauelemente ohne zusätzliche Befestigungsmaßnahmen ergibt. Bei einer vor­zugsweisen Ausführungsform sind die Randprofile mit einem hakenförmigen Profil ausgeführt. Auch an diese Randprofile können entsprechende Befestigungselemente formschlüssig ange­setzt werden.The two edge profiles of the shell halves lying on the edge of the component are preferably designed with a corresponding profile that interlocks when two components are assembled, so that a reliable connection of adjacent components results in a simple manner without additional fastening measures. In a preferred embodiment, the edge profiles are designed with a hook-shaped profile. Corresponding fastening elements can also be positively attached to these edge profiles.

Bei einer bevorzugten Ausführungsform der Erfindung sind die beiden Schalenhälften mit ihren Randprofilen aus Metall, vorzugsweise Stahl oder Aluminium, die Deckschicht aus einem Gewebe oder einer Folie, vorzugsweise aus Kunststoff, der Stützkern aus Polyurethan-Hartschaum und der Dichtungs­streifen aus Polyurethan-Weichschaum hergestellt. Mit Hilfe dieser Materialien läßt sich ein hochbelastbares und witte­rungsbeständiges Bauelement auf besonders preiswerte Weise herstellen.In a preferred embodiment of the invention, the two shell halves with their edge profiles are made of metal, preferably steel or aluminum, the cover layer is made of a fabric or a film, preferably of plastic, the support core is made of rigid polyurethane foam and the sealing strip is made of flexible polyurethane foam. With the help of these materials, a highly resilient and weather-resistant component can be manufactured in a particularly inexpensive manner.

  • 2 shows a corresponding cross section through the folded component,

Das plattenförmige Bauelement umfaßt jeweils eine aus zwei Schalenhälften 1a und 1b bestehende Unterschale 1. Diese Schalenhälften 1a und 1b weisen an ihren in Längsrichtung des Bauelements verlaufenden Rändern einstückig angeformte oder nachträglich angesetzte Randprofile 2a bzw. 2b auf. Beim Aus­führungsbeispiel ist jede Schalenhälfte 1a und 1b weiterhin mit zwei in Längsrichtung verlaufenden, schwalbenschwanz­förmig ausgebildeten Nuten 3 versehen. Diese werden ebenfalls wie die Randprofile 2a und 2b durch entsprechendes Abkanten einstückig aus dem Material der Unterschale 1 hergestellt, vorzugsweise aus Stahl oder Aluminium.The plate-shaped component in each case comprises a lower shell 1 consisting of two shell halves 1a and 1b. These shell halves 1a and 1b have, at their edges running in the longitudinal direction of the component, integrally molded or subsequently attached edge profiles 2a or 2b. In the exemplary embodiment, each shell half 1a and 1b is further provided with two grooves 3 which run in the longitudinal direction and have a dovetail shape. Like the edge profiles 2a and 2b, these are also produced in one piece from the material of the lower shell 1, preferably from steel or aluminum, by appropriate folding.

Die in der Längsmitte des aus den beiden Schalenhälften 1a und 1b gebildeten Bauelements nebeneinanderliegenden Rand­profile 2b sind miteinander durch einen Dichtungsstreifen 4 verbunden, der aus einem biegsamen Material, beispielsweise Polyurethan-Weichschaum hergestellt ist. Der Dichtungs­streifen 4 liegt auf entsprechenden Flächen der beiden Rand­profile 2b auf, wie dies insbesondere aus Fig.1 hervorgeht. Auch an den außenliegenden Randprofilen 2a der beiden Schalenhälften 1a und 1b können Dichtstreifen 5 angeordnet sein, wie dies die Figuren 1 und 2 zeigen und die auf ent­sprechenden Flächen der Randprofile 2a befestigt sind. Beim Ausführungsbeispiel sind die Randprofile 2a in der Art eines Hakens ausgeführt. Diese Haken greifen bei einem Aneinander­ fügen benachbarter Bauelemente formschlüssig ineinander, wie dies in Fig.3 dargestellt ist.The edge profiles 2b lying next to one another in the longitudinal center of the component formed from the two shell halves 1a and 1b are connected to one another by a sealing strip 4, which is made of a flexible material, for example flexible polyurethane foam. The sealing strip 4 lies on corresponding surfaces of the two edge profiles 2b, as can be seen in particular from FIG. Sealing strips 5 can also be arranged on the outer edge profiles 2a of the two shell halves 1a and 1b, as shown in FIGS. 1 and 2 and which are fastened on corresponding surfaces of the edge profiles 2a. In the exemplary embodiment, the edge profiles 2a are designed in the manner of a hook. These hooks engage with each other join adjacent components in a form-fitting manner, as shown in Fig.3.

Über die gesamte durch die beiden Schalenhälften 1a und 1b gebildete Breite des Bauelements verläuft eine biegsame Deck­schicht 6, beispielsweise aus einem Gewebe oder einer Folie, vorzugsweise aus Kunststoff. Beim Ausführungsbeispiel ist diese biegsame Deckschicht 6 an einer Längskante mit einem über das Randprofil 2a überstehenden Randstreifen 6a ausge­bildet, der beim Zusammenbau benachbarter Bauelemente den entstehenden Stoß überdeckt und in geeigneter Weise mit der Deckschicht 6 des benachbarten Bauelements verbunden, bei­spielsweise verschweißt oder verklebt wird.A flexible cover layer 6, for example made of a fabric or a film, preferably made of plastic, extends over the entire width of the component formed by the two shell halves 1a and 1b. In the exemplary embodiment, this flexible cover layer 6 is formed on one longitudinal edge with an edge strip 6a which projects beyond the edge profile 2a and which covers the resulting joint when assembling adjacent components and is connected in a suitable manner to the cover layer 6 of the adjacent component, for example welded or glued.

Der zwischen den Beiden Schalenhälften 1a und 1b der Unter­schale 1 und der durchgehenden Deckschicht 6 entstehende Zwi­schenraum wird durch einen Stützkern 7 aus geschäumtem Iso­liermaterial ausgefüllt, das hierbei die Unterschale 1 mit der Deckschicht 6 großflächig verbindet. Vorzugsweise wird Polyurethan-Hartschaum als Isoliermaterial verwendet, das zu­gleich den auf den Randprofilen 2b aufliegenden Dichtungs­streifen 4 sowie die an den Randprofilen 2a angeordneten Dichtstreifen 5 einschäumt und damit zusätzlich festhält.The space created between the two shell halves 1a and 1b of the lower shell 1 and the continuous cover layer 6 is filled by a support core 7 made of foamed insulating material, which here connects the lower shell 1 to the cover layer 6 over a large area. Rigid polyurethane foam is preferably used as the insulating material, which at the same time foams the sealing strips 4 resting on the edge profiles 2b and the sealing strips 5 arranged on the edge profiles 2a and thus also holds them in place.

Durch die Bildung der Unterschale 1 aus zwei voneinander ge­trennten Schalenhälften 1a und 1b lassen sich auch bei vorge­gebener maximaler Herstellbreite für die Schalenhälften 1a und 1b doppelt breite Bauelemente herstellen, weil es unpro­blematisch ist, entsprechend breite Deckschichten 6 herzu­stellen. Diese gegen örtliche Überbelastung empfindliche Deckschicht 6 wird bei der Lagerhaltung und beim Transport der Bauelemente dadurch geschützt, daß gemäß Fig.2 die beiden Schalenhälften 1a aus der in Fig.1 gestreckten Lage um 180° gegeneinander geschwenkt und damit zusammengefaltet werden.By forming the lower shell 1 from two separate shell halves 1a and 1b, double-width components can be produced for the shell halves 1a and 1b even with a predetermined maximum production width, because it is unproblematic to produce correspondingly wide cover layers 6. This cover layer 6, which is sensitive to local overload, is protected during storage and during transport of the components in that, according to FIG. 2, the two shell halves 1a are pivoted against one another from the position shown in FIG. 1 and are thus folded together.

In dieser gefalteten Lage gemäß Fig.2 liegt die die beiden Schalenhälften 1a und 1b abdeckende Deckschicht 6 aufeinander und vor äußeren Einflüssen geschützt. Außerdem kann das Bau­element in dieser zusammengefalteten Lage auch dann transpor­tiert werden, wenn die Transportbreiten begrenzt sind.In this folded position according to FIG. 2, the cover layer 6 covering the two shell halves 1a and 1b lies on top of one another and is protected from external influences. In addition, the component can be transported in this folded position even when the transport widths are limited.

In Fig.4 sind drei verschiedene Möglichkeiten zur Befestigung des Bauelements in dessen Randbereich an einer Unterkon­struktion dargestellt. So ist im vorderen Teil der Fig.4 ein doppel-T-förmiger Träger 8 zu erkennen, auf dessen oberen Flansch von der Seite her zwei Befestigungselemente 9 aufge­setzt sind, die mit einem hakenförmigen Teil in das haken­förmig ausgebildete Randprofil 2a des dargestellten Bau­elements eingreifen. Die mittlere Darstellung in Fig.4 zeigt ähnliche Befestigungselemente 10, die seitlich an einen Holz­balken 11 angeschraubt sind. Die obere Darstellung in Fig.4 zeigt ein auf die Oberseite des Holzbalkens 11 aufge­schraubtes Befestigungselement 12. Alle drei dargestellten Ausführungsbeispiele derartiger Befestigungselemente 9, 10 und 12 behindern nicht den Anschluß eines weiteren Bau­elements, wenn dies mit seinem hakenförmigen Randprofil 2a von oben her in das dargestellte Randprofil 2a gemäß Fig.4 eingesetzt wird.4 shows three different possibilities for fastening the component in its edge area on a substructure. In the front part of FIG. 4, a double-T-shaped carrier 8 can be seen, on the upper flange of which two fastening elements 9 are placed from the side, which engage with a hook-shaped part in the hook-shaped edge profile 2a of the component shown. The middle representation in FIG. 4 shows similar fastening elements 10 which are screwed laterally onto a wooden beam 11. The upper illustration in FIG. 4 shows a fastening element 12 screwed onto the top of the wooden beam 11. All three illustrated exemplary embodiments of such fastening elements 9, 10 and 12 do not hinder the connection of a further component if this with its hook-shaped edge profile 2a from above into the edge profile 2a shown in FIG. 4 is used.

Um das voranstehend beschriebene Bauelement auch in der Mitte entweder auf einer Tragkonstruktion befestigen oder ander­weitig verankern zu können, sind Befestigungselemente 13 vor­gesehen, von denen ein Ausführungsbeispiel in Fig.5 per­spektivisch dargestellt ist. Diese Befestigungselemente 13 greifen in eine Aussparung 14 ein, die durch die beiden in der Mitte des Bauelements nebeneinanderliegenden Randprofile 2b in der gestreckten Lage der Schalenhälften 1a und 1b ge­bildet wird, wie dies die Figuren 1 und 3 zeigen.In order to be able to either fasten or otherwise anchor the component described above in the middle on a supporting structure, fastening elements 13 are provided, of which an exemplary embodiment is shown in perspective in FIG. These fastening elements 13 engage in a recess 14, which is formed by the two edge profiles 2b lying next to one another in the center of the component in the extended position of the shell halves 1a and 1b, as shown in FIGS. 1 and 3.

Durch diese Ausbildung ist es möglich, das im zusammenge­falteten Zustand angelieferte Bauelement auch in seiner Mitte beispielsweise gemäß Fig.3 an einem Holzbalken 11 zu befe­stigen, indem auf diesem Holzbalken Befestigungselemente 13 gemäß Fig.5 angeordnet werden, bevor das jeweilige Bauelement durch Aufklappen der oben liegenden Schalenhälfte in die ge­streckte Lage gebracht wird, in der die Befestigungselemente 13 formschlüssig in die durch Aufklappen gebildete Aussparung 14 eingreifen, wie dies im rechten Teil der Fig.3 angedeutet ist.This design makes it possible to fasten the component delivered in the folded state to a wooden beam 11 in the middle, for example according to FIG. 3, by arranging fastening elements 13 according to FIG. 5 on this wooden beam before the respective component is opened by opening the top lying shell half is brought into the extended position, in which the fasteners 13 engage positively in the recess 14 formed by opening, as indicated in the right part of Figure 3.
