Description

AT 396 273 BAT 396 273 B

Die Erfindung betrifft eine Eckverbindung für Bauplatten von Einrichtungen für Land-, Wasser- und Luftfahrzeuge, insbesondere Passagierflugzeuge, wobei jede Bauplatte aus einem vorzugsweise wärmeisolierenden Kern besteht, der beidseitig mit zumindest einer Deckschicht überzogen ist sowie ein Verfahren zur Herstellung der Eckverbindung.The invention relates to a corner connection for building boards of devices for land, water and aircraft, in particular passenger aircraft, each building board consisting of a preferably heat-insulating core, which is covered on both sides with at least one cover layer, and a method for producing the corner connection.

Unter Einrichtungen werden hiebei Servicewagen, Kühl- oder Wärmeschränke, Gepäckablagen, Bordküchen, Toilettekabinen usw. verstanden, die leicht, dicht, steif, vibrationsfest, schlagfest, langzeitstabil und z. T. wärmeisolieiend ausgebildet sein sollen. Diese Einrichtungen müssen außerdem Anforderungen von Seiten der Brennbarkeit, Rauchgasdichte und -Zusammensetzung entsprechen, die ihrerseits die Auswahl bestimmter Bauweisen und bestimmt» Konstruktionselemente erfordern. Herkömmliche Einrichtungen der genannten Art »füllen diese Forderungen nur teilweise oder ungenügend, da die dafür verwendeten Bauplatten meist durch Schraub- oder Nietverbindungen, mit zumeist metallischen Rahmen oder Trägem verbunden werden, die sich im Laufe derZeit lösen können.Facilities are understood to mean service trolleys, refrigerators or warmers, luggage racks, galley kitchens, toilet cubicles, etc., which are light, tight, rigid, vibration-resistant, impact-resistant, long-term stable and e.g. T. should be designed heat-insulating. These facilities must also meet flammability, flue gas density and composition requirements, which in turn require the selection of certain types of construction and specific construction elements. Conventional devices of the type mentioned »fill these requirements only partially or insufficiently, since the building boards used for this are mostly connected by screw or rivet connections, mostly with metallic frames or supports, which can come loose in the course of time.

In der AT-PS 384.189 sind Bauplatten beschrieben, die das Eigenschaftsprofil gut erfüllen. Das Verbinden von genannten Bauplatten erfolgte bislang nach dem Stand der Technik mit Schraubverbindungen an speziell verstärkten Stellen der Bauplatte. Metallische Einsätze oder das Ausfüllen des Kernes wurden zur Verstärkung des Kernes verwendet. Dies hatte erhebliche Gewichtsnachteile.In AT-PS 384.189, building boards are described that meet the property profile well. To date, the aforementioned building boards have been connected using screw connections at specially reinforced points on the building board. Metallic inserts or core filling were used to reinforce the core. This had significant weight disadvantages.

Durch die EP-A218 658 ist eine als Dekorgebüde dienende Platte bekannt geworden, die aus Elementen besteht, welche untereinander gelenkig verbunden sind und aus flächigen Bauelementen bestehen. Zwischen den Bauelementen des bekannten Gebildes sind keine Kerne vorhanden.From EP-A218 658 a plate serving as a decorative building has become known, which consists of elements which are articulated to one another and which consist of flat components. There are no cores between the components of the known structure.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kem im Eckbereich zwei» zu verbindender Bauplatten zumindest auf einem Teil sein» Breite und bzw. oder Höhe auf eine vorbestimmte Tiefe entfernt ist, sodaß die beiden Deckschichten und allenfalls noch vorhandene Kcmteile mit dem verbleibenden Kem eine Nut bilden, daß die Bauplatten in einem gewünschten Winkel zueinander angeordnet sind, daß in jede Nut ein Kunststoff-Hohlprofil eingesetzt ist, daß der Zwischenraum zwischen den Deckschichten und den Hohlprofilen mit einem ausgehärteten Kleb» sowie im Eckbereich innen und außenseitig mit klebcrgetränktem, ausgehärteten Fasergewebe ausgefüllt ist, wobei das außenseitige Fasergewebe einen abgerundeten äußeren Eckbereich bildet.This object is achieved according to the invention in that the core in the corner region of two "building boards to be connected is at least partially removed" in width and / or height to a predetermined depth, so that the two cover layers and any remaining core parts with the remaining core Form groove, that the building boards are arranged at a desired angle to each other, that a plastic hollow profile is inserted in each groove, that the space between the cover layers and the hollow profiles with a hardened adhesive »and inside and outside with adhesive-soaked, hardened fiber fabric in the corner area is filled, the outside fiber fabric forming a rounded outer corner area.

Das Verfahren zur Herstellung der Eckverbindung ist erfindungsgemäß dadurch gekennzeichnet, daß der Kem im Eckbereich der zwei zu verbindenden Bauplatten auf eine vorbestimmte Tiefe entfernt wird, sodaß die beiden Deckschichten mit dem verbleibenden Kem eine Nut bilden, daß die Bauplatten in einem gewünschten Winkel zueinander angeordnet werden, wobei sich die Kanten der zusammenstoßenden inneren Deckschichten berühren, daß in jede Nut ein Kunststoff-Hohlprofil eingesetzt wird, welches zuvor außen mit einem aushärtbaren Kleb» bestrichen und im Eckbereich außen und innen mit einem klcbcrgetiänkten Fasergewebe belegt wird, und daß anschließend die Aushärtung des Klebers unter Bildung eines abgerundeten äußeren Eckbereichs sowie gegebenenfalls eines ebenen, bündig an die äußeren Deckschichten anschließenden Bereichs durch Pressen während des Aushärtens erfolgtThe method for producing the corner connection is characterized according to the invention in that the core in the corner region of the two building boards to be connected is removed to a predetermined depth, so that the two cover layers form a groove with the remaining core, that the building boards are arranged at a desired angle to one another , whereby the edges of the colliding inner cover layers touch each other, that a hollow plastic profile is inserted into each groove, which is previously coated with a curable adhesive on the outside and covered with a clogged fiber fabric on the outside and inside, and that the curing of the Adhesive to form a rounded outer corner area and optionally a flat area that is flush with the outer cover layers by pressing during curing

Weitere Merkmale und Einzelheiten der Erfindung werden nachfolgend anhand der Zeichnung erläutert Es zeigen Fig. 1 eine Eckverbindung gemäß der Erfindung im Qu»schnitt und Fig. 2 und 3 zwei Varianten nach Fig. 1 in schematischer Darstellung. In Fig. 1 bezeichnen (1) und (2) zwei miteinander zu verbindende Bauplatten, die einen Kem (3) und Deckschichten (4, 5) aufweisen, wobei die Deckschichten mit ein» Dekorfolie (nicht dargestellt) überzogen sein können. Die Deckschichten (4, 5) bestehen aus Kunststoff, während der Kem (3) aus kunststoffbeschichtetem Papier oder Pappe in Waben- oder Wellform besteht Im dargestellten Beispiel sind die Bauplatten (1) und (2) im rechten Winkel zueinander angeordnet Wie aus Fig. 2 und 3 ersichtlich ist, können die Bauplatten (1,2) ab» auch entweder einen stumpfen Winkel (o) oder einen spitzen Winkel (ß) zueinander einnehmen, wie spät» erläutert wird. Die Kanten der inneren Deckschichten (4) berühren sich im Eckbereich, sodaß ein Zwickel zwischen den äußeren Deckschicht»! (5) entsteht, der ausgefüllt werden muß, wie anschließend »läutert wird. Der Kem (3) wird bis zu einer vorbesfimmten Tiefe (T) vom Rand entfernt z. B. durch Fräsen. Durch den verbleibenden Kemboden und die beiden Deckschichten entsteht eine Nut In jede Nut wird ein Kunststoff-Hohlprofil (6) eingeschoben, das im Qu»schnitt längsoval ausgebildet ist wobei das dem Kem (3) nähere Ende abgerundet und das vom Kem (3) entfernte Ende abgeschrägt und an den Übergangsstellen ebenfalls abgerundet ist Der Winkel der Abschrägung beträgt in diesem Fäll 45°, so daß sich die schrägen Enden flächig berühren. Vor dem Einschieben in die Nuten w»den die Hohlprofile (6) mit einem aushärtbaren Kleber bestrichen und im Eckbereich mit mehreren klebergetränkten Fasergeweben (7) beidseitig belegt. Aus Grünten d» Übersicht sind nur einige Fasergewebe (7) dargestellt. Das Fasergewebe (7) ist vorzugsweise ein Glasfasergewebe. Diese Anordnung wird anschließend zum Aushärten des Klebers in eine, aus zwei abgewinkelten Formen (8, 9) bestehende Preßvorrichtung eingebracht Die äußere Form (8) weist im Eckbereich eine Abrundung mit einem gewünschten Radius (R) auf, während die innere Form (9) eckig ist Durch den Preßvorgang verteilt sich der Kleber gleichmäßig in den Zwischenräumen und das mit Kleber imprägnierte Fasergewebe (7) paßt sich genau der Rundung der Form (8) an und bildet einen ebenen, an die Deckschichten (5) bündig anschließenden Übergangsbereich. Zweckmäßig wird die Breite des Fasergewebes der äußeren Lagen bei der Rundung so gewählt daß sie am Beginn der Deckschicht (5) enden. Als Kleber wird -2-Further features and details of the invention are explained below with reference to the drawing. FIG. 1 shows a corner connection according to the invention in cross section and FIGS. 2 and 3 show two variants according to FIG. 1 in a schematic representation. In Fig. 1, (1) and (2) denote two building boards to be connected to one another, which have a core (3) and cover layers (4, 5), it being possible for the cover layers to be covered with a »decorative film (not shown). The cover layers (4, 5) are made of plastic, while the core (3) consists of plastic-coated paper or cardboard in honeycomb or corrugated form. In the example shown, the building boards (1) and (2) are arranged at right angles to one another. 2 and 3 it can be seen that the building boards (1, 2) can also make either an obtuse angle (o) or an acute angle (ß) to each other, as will be explained later ». The edges of the inner cover layers (4) touch in the corner area, so that a gusset between the outer cover layers »! (5) arises, which has to be filled in, as is subsequently explained. The core (3) is removed to a predetermined depth (T) from the edge z. B. by milling. A groove is created through the remaining core bottom and the two cover layers. A hollow plastic profile (6) is inserted into each groove, which is longitudinally oval in cross section, the end closer to the core (3) being rounded and the end removed from the core (3) The end is chamfered and also rounded at the transition points. The angle of the chamfer in this case is 45 °, so that the oblique ends touch each other. Before being pushed into the grooves, the hollow profiles (6) are coated with a hardenable adhesive and covered in the corner area with several adhesive-soaked fiber fabrics (7) on both sides. From Grünten d »overview only a few fiber fabrics (7) are shown. The fiber fabric (7) is preferably a glass fiber fabric. This arrangement is then introduced into a pressing device consisting of two angled molds (8, 9) in order to harden the adhesive. The outer mold (8) has a rounding with a desired radius (R) in the corner area, while the inner mold (9) is angular Through the pressing process, the adhesive is evenly distributed in the gaps and the fiber fabric (7) impregnated with adhesive adapts exactly to the curve of the shape (8) and forms a flat transition area which is flush with the cover layers (5). The width of the fiber fabric of the outer layers is expediently chosen during the rounding so that they end at the beginning of the cover layer (5). As an adhesive, -2-
