Description

Die Erfindung betrifft ein Befestigungssystem für Kompaktplatten aus einer oder mehreren miteinander heißverpreßten, mit Harz imprägnierten Faserschichten, die außen an zumindest einer Seite mit einer Dekorschicht beschichtet sind, zur unsichtbaren Montage auf einem Grundkörper.The invention relates to a fastening system for compact panels made of one or more fiber layers which are hot-pressed together and impregnated with resin and which are coated on the outside on at least one side with a decorative layer, for invisible mounting on a base body.

Der Aufbau von Kompaktplatten, insbesondere von sogenannten HPL (high pressure laminate)-Kompaktplatten, ist nach DIN 16926 bzw. ISO 4586 festgelegt. Unter den Begriff Kompaktplatten fallen auch solche Platten, die einen der DIN- oder ISO-Norm sehr ähnlichen Aufbau besitzen. Die Komponenten derartiger Kompaktplatten werden aus den gleichen Materialien in den gleichen Hochdruckpressen hergestellt wie alle HPL-Platten und enthalten, je nach Formungsverfahren, fallweise Klebeschichten. Die ein- bzw. beidseitige dekorative Farbgebung der Kompaktplatte kann auf einer glatten oder strukturierten Oberfläche vorgenommen werden.The structure of compact sheets, especially so-called HPL (high pressure laminate) compact sheets, is defined in accordance with DIN 16926 and ISO 4586. The term compact panels also includes panels that have a structure very similar to the DIN or ISO standard. The components of such compact sheets are made from the same materials in the same high-pressure presses as all HPL sheets and, depending on the molding process, contain adhesive layers from case to case. The decorative coloring of the compact panel on one or both sides can be carried out on a smooth or structured surface.

Der Kern von HPL-Kompaktplatten besitzt eine sehr große Festigkeit und kann daher große Kräfte aufnehmen, ohne zu Bruch zu gehen oder sich zu verformen.The core of HPL compact panels is very strong and can therefore absorb large forces without breaking or deforming.

Derartige Platten werden insbesondere für Fassaden- und Wandverkleidungen aufgrund ihrer hohen Witterungs- und Formbeständigkeit eingesetzt, wobei darauf geachtet wird, daß die Befestigung der Platten an einer Wand oder einem Grundkörper von außen her unsichtbar ist. Solche unsichtbaren Befestigungen werden bisher für HPL-Kompaktplatten in der Weise realisiert, daß diese Platten geklebt oder mittels Schrauben befestigt werden. Bei Schraubverbindungen erfolgen diese direkt mit den Kompaktplatten, wobei im allgemeinen die Dübel in den Platten stecken. Die Verbindung mit der dahinter liegenden Wand bzw. mit dem dahinter befindlichen Grundkörper geschieht über Bügel. Bei einer Wandbefestigung der Kompaktplatten werden im allgemeinen die Schraubverbindungen mit Hilfe von Dübeln in den Platten hergestellt. Dabei ist es wegen der hohen Biegesteifigkeit bei den Kompaktplatten erforderlich, abhängig von der Belastung und dem Format der Kompaktplatte, relativ viele Befestigungspunkte vorzusehen, wodurch die gesamte Montage vor Ort zeitaufwendig und dementsprechend teuer wird. Unterschiedliche Plattenformate, bei unsichtbar befestigten Kompaktplatten, erfordern meist komplizierte Bearbeitungsschritte auf der Baustelle oder zusätzliche Bearbeitungsschritte in der Werkhalle für die Vorbereitung der Kompaktplatten.Such panels are used in particular for facade and wall cladding due to their high weather and shape stability, care being taken to ensure that the panels are fastened is invisible from the outside on a wall or a body. Such invisible fastenings have so far been realized for HPL compact panels in such a way that these panels are glued or fastened by means of screws. In the case of screw connections, these are made directly with the compact panels, with the dowels generally being inserted in the panels. The connection to the wall behind or to the basic body located behind is made via brackets. When the compact panels are attached to the wall, the screw connections are generally made using dowels in the panels. It is necessary because of the high bending stiffness of the compact plates, depending on the load and the format of the compact plate, to provide a relatively large number of fastening points, as a result of which the entire assembly on site is time-consuming and accordingly expensive. Different panel formats, with invisibly attached compact panels, usually require complicated processing steps on the construction site or additional processing steps in the workshop to prepare the compact panels.

Zur Herstellung von Eckverbindungen in Holz und für die Linearführung von Schlitten oder dergleichen Maschinenteilen ist es bekannt, Nut- und Federverbindungen bzw. Führungsnuten und mit diesen im Eingriff befindliche Gleitstücke zu verwenden, die den gleichen Querschnitt wie die Führungsnut besitzen, und in diese eingepaßt sind.For the production of corner connections in wood and for the linear guidance of carriages or similar machine parts, it is known to use tongue and groove connections or guide grooves and slides in engagement therewith, which have the same cross-section as the guide groove and are fitted into them .

Aufgabe der Erfindung ist es, für Platten, die für witterungsfeste Verkleidungen verwendet werden, ein Befestigungssystem zu schaffen, bei dem die Platten über das Gesamtmaß ihres Formats befestigt werden können und eine weitgehend spannungsfreie Verbindung von Platten und dahinter liegender Wand oder eines Grundkörpers ermöglicht wird.The object of the invention is a for panels that are used for weatherproof cladding To create fastening system in which the plates can be fastened over the entire size of their format and a largely tension-free connection of plates and the wall or base body behind it is made possible.

Diese Aufgabe wird erfindungsgemäß in der Weise gelöst, daß das Befestigungssystem aus einem Profil besteht, das die Kompaktplatten und eine Wand bzw. einen Grundkörper miteinander verbindet, und daß in den dem Grundkörper zugewandten Seiten der Kompaktplatten Fräsungen angebracht sind, deren Querschnitte sich mit Teilstücken des Profils decken.This object is achieved in such a way that the fastening system consists of a profile that connects the compact plates and a wall or a base body, and that in the sides of the base plate facing the base body are milled, the cross-sections of which sections with the Profiles cover.

In Ausgestaltung der Erfindung weist die einzelne Fräsung eine Tiefe auf, die im Bereich von einem Drittel bis zur Hälfte der Dicke d der Kompaktplatte liegt und erstreckt sich die Fräsung über einen Teil oder über das Gesamtmaß der Kompaktplatte.In an embodiment of the invention, the individual milling has a depth that is in the range from one third to half the thickness d of the compact plate and the milling extends over part or over the entire dimension of the compact plate.

Die Erfindung wird in der Weise weitergestaltet, daß die Fräsung einen schwalbenschwanzförmigen Querschnitt aufweist und ein schwalbenschwanzförmiges Teilstück des Profils aufnimmt.The invention is further developed in such a way that the milling has a dovetail cross section and receives a dovetail section of the profile.

Die weitere Ausgestaltung der Erfindung ergibt sich aus den Merkmalen der Schutzansprüche 4 bis 12.The further embodiment of the invention results from the features of claims 4 to 12.

Mit der Erfindung werden die Vorteile erzielt, daß in Richtung der Längsachse des Profils die Kompaktplatten frei beweglich sind, so daß die wegen unterschiedlicher Materialien von Kompaktplatte und Wand bzw. Grundkörper auftretenden thermischen und hygroskopischen Unterschiede der Materialien aufgenommen und kompensiert werden können. Durch die Befestigung der Kompaktplatte auf dem Profil ergibt sich in Abhängigkeit von der Fräsung- und Profil-Dimensionierung sowie vom Profilmaterial eine Erhöhung der Biegesteifigkeit der Kombination Kompaktplatte - Profil, in Richtung der Längsachse des Profils, senkrecht zur Plattenoberfläche. Durch die richtige Dimensionierung wird die Verbindung Kompaktplatte - Profil - Wand bzw. - Grundkörper spannungsfrei gehalten.With the invention, the advantages are achieved that the compact plates are freely movable in the direction of the longitudinal axis of the profile, so that the thermal and hygroscopic differences in the materials occurring due to different materials of the compact plate and wall or base body are recorded and can be compensated. By attaching the compact plate to the profile, depending on the milling and profile dimensioning as well as the profile material, there is an increase in the bending stiffness of the combination compact plate - profile, in the direction of the longitudinal axis of the profile, perpendicular to the plate surface. Correct dimensioning keeps the connection between the compact panel - profile - wall or base body tension-free.

Die Erfindung wird anhand von zeichnerisch dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:

Eine Kompaktplatte 3 weist im unteren Teil eine Fräsung 5 mit einem schwalbenschwanzförmigen Querschnitt auf. Die Fräsung 5 erstreckt sich über die Gesamtlänge der Kompaktplatte 3 oder nur über einen Abschnitt der Kompaktplatte, wie dies in Figur 1 durch die gestrichelten Linien angedeutet ist. Ein Profil 2 ist aus zwei Teilstücken 10 und 20 zusammengesetzt, wobei das eine Teilstück 20 einen auf den Kopf gestellten L-förmigen Querschnitt aufweist. Das andere Teilstück 10 schließt mittig an den waagerechten Schenkel des Teilstücks 20 an und hat einen schwalbenschwanzförmigen Querschnitt, der nahtlos in die Fräsung 5 der Kompaktplatte 3 einschiebbar ist. Das Teilstück 20 ist in einen Einschnitt 24 eines Grundkörpers 4 formschlüssig einsetzbar. Dieser Grundkörper 4 ist beispielsweise ein U-förmiger Metallträger, der vertikal in einem Stahlgerüst angeordnet ist, das den Umriß eines Hauses festlegt oder der an der Wand eines Gebäudes oder eines Raumes als Unterbau für die Wandverkleidung befestigt ist. Der Einschnitt 24 befindet sich in den beiden Seitenwänden 23 des Grundkörpers 4.A compact plate 3 has a milling 5 in the lower part with a dovetail cross section. The milling 5 extends over the entire length of the compact plate 3 or only over a section of the compact plate, as is indicated in FIG. 1 by the dashed lines. A profile 2 is composed of two sections 10 and 20, with one section 20 one upside down L-shaped cross section. The other section 10 connects centrally to the horizontal leg of section 20 and has a dovetail cross-section that can be inserted seamlessly into the milling 5 of the compact plate 3. The section 20 can be positively inserted into an incision 24 in a base body 4. This base body 4 is, for example, a U-shaped metal support, which is arranged vertically in a steel frame, which defines the outline of a house or which is attached to the wall of a building or a room as a substructure for the wall covering. The incision 24 is located in the two side walls 23 of the base body 4.

Das Material des Profils 2 ist im allgemeinen anders als das Material der Kompaktplatte 3, die aus einer oder mehreren miteinander heißverpreßten, mit Harz imprägnierten Faserschichten besteht, die den Kern der Kompaktplatte bilden. Die beiden Außenseiten dieses Kerns sind jeweils mit einer Dekorplatte bez. Dekorschicht beschichtet.The material of the profile 2 is generally different from the material of the compact plate 3, which consists of one or more resin-impregnated fiber layers which form the core of the compact plate. The two outer sides of this core are each covered with a decorative plate. Decorative layer coated.

Figur 2 zeigt ausschnittsweise und im vergrößerten Maßstab das Befestigungssystem 1 mit dem Profil 2 und der Kompaktplatte 3. In die Fräsung 5, die, wie schon zuvor erwähnt wurde, einen schwalbenschwanzförmigen Querschnitt besitzt, ist das Teilstück 10 des Profils 2 eingesetzt. Der Umriß bzw. Querschnitt des Teilstücks 10 ist gleichfalls schwalbenschwanzförmig ausgebildet und fügt sich ohne Spiel ein. Die Fräsung 5 weist eine Tiefe t auf, die im Bereich von einem Drittel bis zur Hälfte der Dicke d, vgl. Figuren 2 und 3a, der Kompaktplatte liegt. Die geringe Tiefe der Fräsung 5 ist möglich, da der Kern der Kompaktplatte 3 große Festigkeit besitzt, so daß schon eine so geringe Tiefe eine mechanisch sehr stabile Verbindung des Profils 2 mit der Kompaktplatte 3 gewährleistet. Das Profil 2 wird mit seinem Teilstück 10 während der Montage seitlich in die Fräsung 5 eingeschoben. Die Länge des Profils 2 kann so gewählt werden, daß sie sich über eine Teillänge, die Gesamtlänge einer Kompaktplatte oder über zwei oder mehr Kompaktplatten erstreckt. Das Profil 2 kann auch auf andere Weise, als in Figur 1 dargestellt, mit einem Grundkörper bzw. mit einer Wand verbunden werden. So ist es beispielsweise möglich, das Teilstück 20 des Profils 2 an beliebig vielen Befestigungspunkten mit einer Wand oder einem Grundkörper zu verschrauben. Durch die Verbindung zwischen Profil 2 und der Kompaktplatte 3, ähnlich einer Nut-Federverbindung, erfolgt das Zusammenfügen bei entsprechend richtiger Dimensionierung der Querschnitte weitgehend spannungsfrei. Abhängig von der Dimensionierung der Fräsung 5 und dem Profil 2 wird durch die Verbindung dieser beiden Teile eine Erhöhung der Biegesteifigkeit in Richtung der Längsachse des Profils (oder Fräsung) der Kompaktplatte 3 senkrecht zu ihrer Oberfläche erhalten. In Richtung der Längsachse des Profils bzw. der Fräsung 5 kann sich die Kompaktplatte 3 frei bewegen, so daß Unterschiede in den thermischen und hygroskopischen Wirkungen der unterschiedlichen Materialien für das Profil 2 und die Kompaktplatte 3 aufgenommen und ausgeglichen werden können.Figure 2 shows a detail and on an enlarged scale, the fastening system 1 with the profile 2 and the compact plate 3. In the milling 5, which, as already mentioned, has a dovetail cross section, the section 10 of the profile 2 is inserted. The outline or cross section of the section 10 is also dovetail-shaped and inserts without play. The milling 5 has a depth t which is in the range from one third to half the thickness d, cf. Figures 2 and 3a, the compact plate. The small depth of the milling 5 is possible because the core of the compact plate 3 has great strength, so that even such a small depth ensures a mechanically very stable connection of the profile 2 to the compact plate 3. The profile 2 is inserted with its portion 10 laterally into the milling 5. The length of the profile 2 can be chosen so that it extends over a partial length, the total length of a compact plate or over two or more compact plates. The profile 2 can also be connected to a base body or to a wall in a different way than shown in FIG. 1. For example, it is possible to screw section 20 of profile 2 to any number of fastening points with a wall or a base body. Due to the connection between profile 2 and the compact plate 3, similar to a tongue and groove connection, the assembly is largely stress-free if the cross sections are dimensioned correctly. Depending on the dimensions of the milling 5 and the profile 2, an increase in the bending rigidity in the direction of the longitudinal axis of the profile (or milling) of the compact plate 3 perpendicular to its surface is obtained by connecting these two parts. The compact plate 3 can move freely in the direction of the longitudinal axis of the profile or the milling 5, so that differences in the thermal and hygroscopic effects of the different materials for the profile 2 and the compact plate 3 can be absorbed and compensated for.

Bei diesem Befestigungssystem können abweichende Formate der Kompaktplatten vor der Montage problemlos berücksichtigt werden, indem beispielsweise die Längen der Profile auf die abweichenden Maße der einen oder anderen Kompaktplatte gekürzt werden. Dadurch können die Bearbeitungs- und Montagezeiten bzw. -kosten niedriggehalten werden, im Vergleich hierzu sind die gängigen Klebetechniken für Kompaktplatten kompliziert, da sie von der Temperatur und der Feuchtigkeit während der Montage abhängen und außerdem etliche Vorarbeiten, wie Entfetten, Grund- und Klebeschichten anbringen, erfordern. Die üblichen Schraubbbefestigungen sind arbeitsaufwendig, da sowohl das Profil und die Kompaktplatte miteinander verschraubt werden müssen als auch das Profil mit der Wand bzw. dem Grundkörper.With this fastening system, different formats of the compact panels can be easily taken into account before assembly, for example by shortening the lengths of the profiles to the different dimensions of one or the other compact panel. This means that processing and assembly times and costs can be kept low.Comparison to this, the common adhesive techniques for compact panels are complicated because they depend on the temperature and humidity during assembly and also do a lot of preparatory work such as degreasing, base and adhesive layers , require. The usual screw fastenings are labor-intensive, since both the profile and the compact plate have to be screwed together, as well as the profile with the wall or the base body.

In den Figuren 3a bis 3d sind verschiedene Befestigungssysteme dargestellt, bei denen jeweils die Kompaktplatten und die Profile aneinander angepaßt sind. Bei dem Befestigungssystem 1, das in Figur 3a schematisch gezeigt ist, beträgt die Tiefe der Fräsung 5 ein Drittel der Dicke d der Kompaktplatte 3. Es handelt sich hierbei um die schon anhand der Figuren 1 und 2 beschriebene schwalbenschwanzförmige Fräsung 5 mit dem Profil 2, dessen Teilstück 10 gleichfalls einen schwalbenschwanzförmigen Querschnitt besitzt und spielfrei in die Fräsung 5 eingeschoben ist.FIGS. 3a to 3d show different fastening systems, in which the compact plates and the profiles are adapted to one another. In the fastening system 1, which is shown schematically in FIG. 3a, the depth of the milling 5 is one third of the thickness d of the compact plate 3. This is the dovetail milling 5 with the profile 2, which has already been described with reference to FIGS. 1 and 2, whose section 10 also has a dovetail cross section and is inserted into the milling 5 without play.

Figur 3b zeigt ein Befestigungssystem 1, bei dem ein Endstück eines Profils 14 V-förmig ausgebildet ist und Teilstücke 11, 11 die Endabschnitte der V-Form bilden. Der Öffnungswinkel α der V-Form beträgt 50 bis 100°. In der Kompaktplatte 3 befindet sich eine entsprechende Fräsung 17, 17 für die Aufnahme des V-förmigen Profils 14. Die Fräsung 17, 17 besteht aus zwei spiegelbildlich zu einer Senkrechten auf die Kompaktplatte 3 angeordneten Querschnitten 7, 7, die schräg zu der Oberfläche der Kompaktplatte 3 verlaufen. Diese Querschnitte schließen gleichfalls einen Winkel von 50 bis 100° miteinander ein und nehmen die vierkantförmigen Teilstücke 11, 11 des Profils 14 auf. Die Tiefe der Fräsung 17, 17 beträgt etwa die halbe Dicke d/2 der Kompaktplatte 3. Die Stirnflächen der Teilstücke 11, 11 sind schräg zu der Oberfläche der Kompaktplatte 3 ausgerichtet.Figure 3b shows a fastening system 1, in which an end piece of a profile 14 is V-shaped and sections 11, 11 form the end sections of the V-shape. The opening angle α of the V shape is 50 up to 100 °. In the compact plate 3 there is a corresponding milling 17, 17 for receiving the V-shaped profile 14.
