Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer Leichtbauplatte, mit zwei Deckplatten, mit einer Mittellage, mit einer sich über die beiden Deckplatten und die Mittellage erstreckenden Schmalfläche, mit einem im Bereich der Schmalfläche angeordneten Riegel und mit einem den Riegel mit den Deckplatten zumindest abschnittsweise verbindenden Montageklebstoff, wobei ein den Riegel mit mindestens einer der zwei Deckplatten zumindest abschnittsweise verbindender Endklebstoff vorgesehen wird, wobei die Wärmebeständigkeit des Endklebstoffs größer als die Wärmebeständigkeit des Montageklebstoffs ist. Ein solches Verfahren ist aus der JP 60004577 A bekannt.The invention relates to a method for producing a lightweight board, with two cover plates, with a central position, with a extending over the two cover plates and the middle layer narrow surface, arranged with a arranged in the region of the narrow bar and with a bar with the cover plates at least partially connecting An assembly adhesive, wherein the bolt with at least one of the two cover plates at least partially connecting end adhesive is provided, wherein the heat resistance of the final adhesive is greater than the heat resistance of the assembly adhesive. Such a method is from the JP 60004577 A known.

Leichtbauplatten (LBPL) sind aus dem Stand der Technik hinlänglich bekannt. Auch im Möbel- und Innenausbau werden diese seit langer Zeit in vielfältiger Weise verwendet. Haupteinsatzgebiet war und ist hier speziell der Türenbau. So ist es vor allem bei Zimmertüren, die also geringen Anforderungen hinsichtlich des Wärme- und Schallschutzes unterliegen, üblich ein Rahmenelement mit einem Wabenkern beidseitig zu beplanken und dieses dann mit den entsprechenden Bohrungen, Fräsungen, etc. zu einem Türelement weiterzuverarbeiten.Lightweight panels (LBPL) are well known in the art. Also in furniture and interior design, these are used for a long time in a variety of ways. The main field of application was and is the door construction here. So it is especially in room doors, which are therefore subject to low requirements in terms of heat and sound insulation, usually a frame member with a honeycomb core on both sides to plank and this then continue to process the corresponding holes, millings, etc. to a door element.

Im gehobenen Einrichtungsbereich wurden ebenfalls Leichbauplatten im Möbelbau eingesetzt, weil durch deren Einsatz sehr große Wandstärken realisiert werden können, die besondere gestalterische Möglichkeiten bieten. In jüngerer Zeit werden auch bei Massenmöbeln verstärkt Leichtbauplatten verwendet, so dass auch ein Einsatz auf breiterem Gebiet wirtschaftlich möglich wird. Damit sind die verschiedenen Vorzüge der Leichtbauplatten einer größeren Schicht von Endverbrauchern zugängig.Leichbauplatten were also used in furniture in the upscale furnishings, because through their use very large wall thicknesses can be realized, which offer special design options. More recently, lightweight panels are increasingly being used in mass-produced furniture used, so that a use in a wider area is economically possible. Thus, the various benefits of lightweight panels of a larger layer of end users are accessible.

Der Hersteller von Möbeln braucht Leichtbauplatten heute nicht mehr selber herzustellen, wie dies früher der Fall war. Mehrere Arbeitsgänge waren dazu notwendig. Zunächst musste ein Rahmen hergestellt werden, eventuell mit mehreren Querriegeln, auf den dann die Decklagen aufgebracht wurden und der die verschiedenen Beschläge aufzunehmen hatte. Zwischen den Decklagen wurden Leichtfaserplatten, mineralische Dämmwolle, Kartonwaben oder ähnliches eingebracht. Damit wurde dem Element mehr Kompaktheit und eventuell auch eine verbesserte Stabilität verliehen. Zumeist mussten in separaten Arbeitsgängen die Deckschichten auch noch aufwändig oberflächenbehandelt werden. So waren als Decklagen furnierte oder anderweitig beschichtete Hartfaserplatten üblich, wobei das fertige Element auch erst durch abschließendes Lackieren seine endgültige Oberfläche erhalten kann.The manufacturer of furniture does not need to manufacture lightweight panels today, as was the case earlier. Several operations were necessary. First, a frame had to be made, possibly with several crossbars, on which the top layers were then applied and which had to accommodate the various fittings. Between the cover layers lightweight fiber boards, mineral insulating wool, cardboard honeycomb or the like were introduced. This gave the item more compactness and possibly improved stability. In most cases, the outer layers also had to be elaborately surface-treated in separate operations. For example, veneered or otherwise coated hardboards were used as cover layers, and the finished element can only be given its final surface by final painting.

Heute werden Leichtbauplatten in zunehmendem Maß auch industriell gefertigt. Dazu wird eine leichte Mittellage mit Deckplatten versehen, zumeist durch Klebung, so dass ein großformatiger, rahmenloser Verbund entsteht. Je nach geforderter Stabilität der Platte werden unterschiedlich dicke Deckplatten, zumeist aus einem Holzwerkstoff wie Span- oder Faserplatte, eingesetzt. Die verwendeten Platten können bereits beschichtet sein, also etwa mit einem Laminat, einer Farbe, einem Druck mit Versiegelung, einer Melaminharzschicht, einem Furnier, etc. versehen sein. Als Mittellagen werden Kartonwaben oder Schaumstoffplatten bevorzugt. Für bestimmte Verwendungszwecke sind möglicher Weise auch Wabenmaterialien aus anderen Materialien als Papier oder Karton sinnvoll. So können dafür dünnste Plattenmaterialien oder auch dünnwandiges Metall, beispielsweise aus Aluminium eingesetzt werden. Es ist aber auch möglich als Mittellagen leichte Holzwerkstoffe wie etwa entsprechende Spanplatten oder Faserplatten oder auch Massivholz geringer Dichte, wie Balsaholz, einzusetzen. Mit entsprechenden Ausnehmungen versehen sind grundsätzlich alle Materialien zum Einsatz als leichte Mittellage möglich. So werden dafür beispielsweise auch Holzarten herangezogen, die zwar nicht besonders geringes Gewicht aufweisen, dafür aber gut verfügbar sind und sich gut mit zerspanenden Werkzeugen bearbeiten lassen. Auch sind leichte Mittellagen aus Halmbündeln, die miteinander verbunden zu flächigen Gebilden aufgeschnitten werden, sodass dann die Länge der Halmabschnitte der Dicke der Mittellage entspricht, bekannt.Today, lightweight panels are increasingly being manufactured industrially. For this purpose, a light middle layer is provided with cover plates, usually by gluing, so that a large-format, frameless composite arises. Depending on the required stability of the plate different thickness cover plates, mostly from a wood material such as chipboard or fiberboard used. The plates used may already be coated, that is to say be provided with a laminate, a paint, a pressure with a seal, a melamine resin layer, a veneer, etc. When For middle layers, cardboard honeycomb or foam boards are preferred. Honeycomb materials made of materials other than paper or cardboard may also be useful for certain purposes. Thus, thinnest plate materials or even thin-walled metal, for example made of aluminum, can be used for this purpose. But it is also possible to use as middle layers of light wood materials such as corresponding chipboard or fiberboard or solid wood low density, such as balsa wood. Provided with corresponding recesses are basically all materials for use as a light middle layer possible. Thus, for example, wood species are used for this, which, although not particularly low weight, but are well available and can be easily edited with cutting tools. Also, light middle layers of bundles of bundles, which are cut together to form flat structures, so that then the length of the stalk sections corresponds to the thickness of the central layer known.

Die so hergestellten Platten werden dann in die gewünschte Größe aufgeteilt. Je nach vorgesehenem Einsatz der erhaltenen Elemente werden diese dann mit Kanten oder Riegeln versehen oder ein zumindest teilweise umlaufender Rahmen wird nachträglich eingebracht. Dies geschieht durch Ausfräsen des Kantenbereichs und nachfolgendes Einkleben eines Rahmenprofils, das wiederum zumeist aus einem Holzwerkstoff besteht. Durch eine entsprechende Profilierung der Kantenausfräsung ist es dabei auch möglich eine Kraft- und/oder formschlüssige Fixierung zu erreichen. Letzteres wird erreicht, indem ein komplementär geformtes Profil durch elastische Verformung der verbliebenen Deckplattenschicht formschlüssig gehalten wird. In vorteilhafter Weise können Kraft- und/oder Formschluss und eine Klebeverbindung kombiniert werden.The plates thus produced are then divided into the desired size. Depending on the intended use of the resulting elements they are then provided with edges or bars or an at least partially encircling frame is subsequently introduced. This is done by milling the edge area and subsequent gluing a frame profile, which in turn consists mostly of a wood material. By an appropriate profiling of Kantenausfräsung it is also possible to achieve a force and / or positive fixation. The latter is achieved by a complementarily shaped profile is held positively by elastic deformation of the remaining cover plate layer. In an advantageous way Force and / or positive connection and an adhesive connection can be combined.

Zudem ist es bekannt, die Kanten und Schmalflächen von beschichteten Massivplatten mit Post- und Softformingverfahren nachzuarbeiten.In addition, it is known to rework the edges and narrow surfaces of coated solid sheets with post and soft-forming processes.

Dabei wird im Allgemeinen unter einem Postformingverfahren eine Flächenbeschichtung der Schmalfläche verstanden, bei der als Kantenmaterial das Beschichtungsmaterial der Ober- und/oder Unterseite benutzt wird. Dabei wird zunächst das Beschichtungsmaterial auf die Ober- beziehungsweise Unterseite eines zu beschichtenden Plattenmaterials aufgebracht. Im Bereich der zu beschichtenden Schmalfläche wird dann ein ausreichender Materialüberstand belassen oder durch geeignetes Abfräsen der Platte erzeugt ("direct Postforming"), der auf geeignete Weise, üblicherweise durch Wärmezufuhr, flexibilisiert wird. Anschließend wird der flexibilisierte Materialüberstand um die zu beschichtende Schmalfläche gebogen und verklebt. Insbesondere kann die Schmalfläche eine Profilierung aufweisen, beispielsweise wird bei Küchenarbeitsplatten ein Viertelstabprofil bevorzugt.In general, a postforming process is understood to mean a surface coating of the narrow surface, in which the edge and / or underside coating material is used as edge material. First, the coating material is applied to the top or bottom of a plate material to be coated. A sufficient material supernatant is then left in the region of the narrow surface to be coated or produced by suitable milling of the plate ("direct postforming"), which is flexibilized in a suitable manner, usually by supplying heat. Subsequently, the flexibilized material supernatant is bent around the narrow surface to be coated and glued. In particular, the narrow surface may have a profiling, for example, a quarter-rod profile is preferred in kitchen worktops.

Unter einem Softformingverfahren wird im Allgemeinen ein nachträgliches Beschichten einer zunächst profilierten Schmalfläche mit einem speziell für die Schmalfläche zugeschnittenen Material verstanden. Es kann sich dabei um das gleiche Material handeln, das für die Beschichtung der Großflächen verwendet wurde.A softforming process is generally understood to be a subsequent coating of a first profiled narrow surface with a material cut to size specifically for the narrow surface. It may be the same material used to coat the large areas.

Ein bisher ungelöstes Problem bei Leichtbauplatten ist eine Möglichkeit der Nachbearbeitung der Schmalflächen, beispielsweise die Herstellung einer Profilkante durch Profilieren sowie Beschichten der Schmalfläche durch die oben genannten Post- oder Softformingverfahren. Die bei den Verfahren während der Bearbeitung auftretenden Temperaturen übersteigen die Wärmebeständigkeit des Montageklebstoffs, so dass der Riegel nicht mehr in Position bleibt und keine saubere Profilkante mehr hergestellt werden kann.A hitherto unsolved problem with lightweight panels is a possibility of reworking the narrow areas, For example, the production of a profile edge by profiling and coating the narrow surface by the above post or Softformingverfahren. The temperatures encountered in the processes during processing exceed the heat resistance of the assembly adhesive, so that the bolt no longer remains in position and a clean profile edge can no longer be produced.

Unter Wärmebeständigkeit wird hierbei insbesondere auf die in DIN EN 14292 gewählte Definition hingewiesen. Im Allgemeinen kann die Wärmebeständigkeit so definiert werden, dass die gewünschte Klebeigenschaft und Klebefunktion eines Klebers bei einer höheren Temperatur, als der durch die Wärmebeständigkeit angegebenen Temperatur, nicht mehr gegeben ist. Mit anderen Worten wird die Wärmebeständigkeit in der physikalischen Einheit der Temperatur angegeben.In this case, heat resistance refers in particular to the definition chosen in DIN EN 14292. In general, the heat resistance can be defined so that the desired adhesive property and adhesive function of an adhesive at a higher temperature than the temperature indicated by the heat resistance is no longer given. In other words, the heat resistance is given in the physical unit of the temperature.

Die DE 33 23 658 A1 beschreibt ein Verfahren zum Herstellen einer Leichtbauplatte, bei dem die Kante der Leichtbauplatte nachbearbeitet wird, indem sie profiliert wird. Anschließend wird im nachbearbeiteten Bereich ein Ummantelungsstreifen, beispielsweise ein Furnierstreifen, aufgeklebt.The DE 33 23 658 A1 describes a method for producing a lightweight board, in which the edge of the lightweight board is reworked by being profiled. Subsequently, a sheathing strip, for example, a veneer strip, glued in the post-processed area.

Die EP 0 292 813 A2 beschreibt ein Verfahren, bei dem ein Umleimteil, beispielsweise ebenfalls ein Furnierstreifen, auf die Kante einer Spanplatte oder eines Bretts aufgeklebt wird, wobei zum Aufkleben zwei verschiedene Klebstoffe verwendet werden.The EP 0 292 813 A2 describes a method in which a gluing, for example, also a veneer strip, is glued to the edge of a chipboard or a board, wherein for gluing two different adhesives are used.

Der Erfindung liegt somit das technische Problem zugrunde, ein Verfahren zur Herstellung einer Leichtbauplatte mit einer Riegelverklebung anzugeben, das eine optimierte Herstellung einer Profilkante, insbesondere durch Post- und Softformingverfahren, ermöglicht.The invention is therefore based on the technical problem of specifying a method for producing a lightweight board with a Biegelverklebung that optimized production a profile edge, in particular by post and Softformingverfahren allows.

Das zuvor aufgezeigte technische Problem wird bei einem Verfahren der eingangs genannten Art dadurch gelöst, dass die Leichtbauplatte im Bereich der Schmalfläche nachbearbeitet wird, wobei bei der Nachbearbeitung die Kante der Leichtbauplatte profiliert wird, und dass der Endklebstoff zwischen der mindestens einen Deckplatte und dem Riegel zumindest außerhalb des Bereiches der Nachbearbeitung angeordnet wird. Ausgestaltungen des Verfahrens sind Gegenstand der Unteransprüche.The aforementioned technical problem is solved in a method of the type mentioned above in that the lightweight board is reworked in the region of the narrow surface, wherein the post of the edge of the lightweight board is profiled, and that the final adhesive between the at least one cover plate and the bolt at least is arranged outside the range of post-processing. Embodiments of the method are the subject of the dependent claims.

Erfindungsgemäß wurde somit erkannt, dass die besonders schnelle Abbindezeit und somit ein besonders schnelles Erreichen der Festigkeit der Verbindung des Riegels mit mindestens einer Deckplatte durch Verwendung des Montageklebstoffs gewährleistet ist. Die sich zwischen Vorsehen des Riegels an der Schmalfläche und dem Nachbearbeiten der Schmalfläche befindenden Arbeitsschritte können somit unverändert schnell durchgeführt werden.According to the invention it has thus been recognized that the particularly fast setting time and thus a particularly rapid achievement of the strength of the connection of the bolt with at least one cover plate is ensured by using the assembly adhesive. The working steps which are present between provision of the bolt on the narrow surface and the reworking of the narrow surface can thus be carried out unchanged as quickly as possible.

Sobald der Endklebstoff ebenfalls seine vorgesehene Festigkeit erreicht hat, kann mit dem Nachbearbeiten, also dem Profilieren und Beschichten der Schmalfläche begonnen werden. Dabei verliert der Endklebstoff nicht seine Klebekraft, da seine Wärmebeständigkeit höher als die des Montageklebstoffs ist und insbesondere höher als die beim Nacharbeiten der Schmalfläche auftretende Temperatur ist.Once the final adhesive has also reached its intended strength, can be started with the reworking, so the profiling and coating of the narrow surface. In this case, the final adhesive does not lose its adhesive power, since its heat resistance is higher than that of the assembly adhesive and in particular is higher than the temperature occurring during reworking of the narrow surface.

In bevorzugter Weise ist der Endklebstoff so angeordnet, dass er an der profilierten Kante zum Vorschein kommt, also nach dem Fräsen an der neuen Oberfläche der Schmalkante zu liegen kommt. Dies ist besonders vorteilhaft, da beim Nachbearbeiten, beispielsweise durch Fräsen oder Soft- bzw. Postforming, im Bereich der Nachbearbeitung eine große Hitze entsteht. Wäre in diesem Bereich nur der Montageklebstoff vorgesehen, könnte die Verbindung des Riegels zu der mindestens einen Deckplatte unzulässig oder vollständig nachlassen. Der Endklebstoff hat allerdings eine ausreichende Wärmebeständigkeit, um der durch die Nachbearbeitung produzierten Hitze zu widerstehen.Preferably, the final adhesive is arranged so that it comes to the profiled edge to light, so comes to lie on the new surface of the narrow edge after milling. This is particularly advantageous because when reworking, for example by milling or soft or Postforming, in the field of post-processing a great heat. If only the assembly adhesive were provided in this area, the connection of the bolt to the at least one cover plate could be inadmissible or completely reduced. However, the final adhesive has sufficient heat resistance to withstand the heat produced by the post-processing.

In einer Ausführungsform ist der Endklebstoff zwischen der mindestens einen Deckplatte und dem Riegel außerhalb des Bereiches der Nachbearbeitung so angeordnet, dass nach der Nachbearbeitung ausschließlich Endklebstoff erhalten geblieben ist und seine Funktion der dauerhaften Verbindung zwischen der Deckplatte und dem Riegel erfüllen kann.In one embodiment, the final adhesive between the at least one cover plate and the bolt outside the range of post-processing is arranged so that after finishing only final adhesive has been preserved and its function of the permanent connection between the cover plate and the latch can meet.

In einer weiteren Ausführungsform ist der Endklebstoff zwischen der mindestens einen Deckplatte und dem Riegel im Bereich der Nachbearbeitung vorgesehen. Dabei wird durch die Nachbearbeitung der Bereich, in dem der Endklebstoff vorgesehen ist, nicht vollständig entfernt, so dass der Endklebstoff an der profilierten Kante zum Vorschein tritt. Während der Nachbearbeitung wird also nur ein Teil des Endklebstoffes entfernt und ein weiterer Teil des Endklebstoffes bleibt erhalten. Dadurch ist nicht nur die Position des Riegels gegenüber den Deckplatten während der Nachbearbeitung gesichert, sondern auch die Festigkeit der durch das Profilieren freigelegten Klebefuge gegeben.In a further embodiment, the final adhesive is provided between the at least one cover plate and the latch in the area of the post-processing. The post-processing does not completely remove the region in which the final adhesive is provided, so that the final adhesive appears on the profiled edge. During post-processing, therefore, only part of the final adhesive is removed and another part of the final adhesive is retained. As a result, not only the position of the bolt against the cover plates is secured during post-processing, but also given the strength of the exposed by the profiling adhesive joint.

In bevorzugter Weise kann der Montageklebstoff ein Schmelzklebstoff oder ein Montageschaum sein. So können eine Vielfalt von bekannten und günstigen Klebstoffen genutzt werden. Insbesondere kann es sich auch um einen Schnellkleber handeln.Preferably, the assembly adhesive may be a hot melt adhesive or a mounting foam. Thus, a variety of known and cheap adhesives can be used. In particular, it may also be a quick adhesive.

Des Weiteren kann der Endklebstoff ebenfalls ein Schmelzklebstoff sein. Dabei muss lediglich ein Schmelzklebstoff gewählt werden, dessen Wärmebeständigkeit höher ist, als die bei der Nacharbeit der Schmalfläche auftretenden Temperaturen.Furthermore, the final adhesive may also be a hot melt adhesive. In this case, only a hot melt adhesive must be selected whose heat resistance is higher than the temperatures occurring during the reworking of the narrow surface.

Insbesondere kann es sich bei den genannten Schmelzklebstoffen um einen nicht reaktiven, einkomponentig reaktiven oder zweikomponentig reaktiven Klebstoff handeln. Beispielhaft, jedoch nicht abschließend, sind hier Äthylen-Vinylacetat (EVA), Äthylen-Acrylsäureester-Copolymerisate (EEA), Polyurethan (PUR), Plyamide (PA), thermoplastische (lineare, gesättigte) Polyester und amorphe Poly-alphaolefine (APAO) sowie reaktive Zusätze wie Isocyanat und Epoxide oder Polyolkomponenten zu nennen. In vorteilhafter Weise kann so auf eine Vielfalt von bekannten und günstigen Schmelzklebstoffen zurückgegriffen werden.In particular, the hotmelt adhesives mentioned may be a non-reactive, one-component reactive or two-component reactive adhesive. Exemplary, but not exhaustive, are here ethylene-vinyl acetate (EVA), ethylene-acrylic acid ester copolymers (EEA), polyurethane (PUR), plyamides (PA), thermoplastic (linear, saturated) polyesters and amorphous poly-alpha-olefins (APAO) and to mention reactive additives such as isocyanate and epoxides or polyol components. Advantageously, a variety of known and cheap hot melt adhesives can be used.

Weiterhin kann der Endklebstoff ein Polyvinylacetatleim (PVAC) sein. Der Endklebstoff kann auch ein Polyurethanklebstoff (PU-Kleber) sein. Dieser hat eine hohe Klebfestigkeit und kann Unebenheiten und dicke Klebstofffugen gut überbrücken.Furthermore, the final adhesive may be a polyvinyl acetate glue (PVAC). The final adhesive may also be a polyurethane adhesive (PU adhesive). This has a high adhesive strength and can bridge unevenness and thick adhesive joints well.

Beispielsweise können auch mehrere Zonen zwischen dem Riegel und der mindestens einen Deckplatte vorgesehen werden. So kann in zwei Zonen der Endklebstoff Verwendung finden, in einer dritten Zone der Montageklebstoff. Dadurch ist eine große Anzahl von Gestaltungsmöglichkeiten gegeben um die Verklebung des Riegels mit der mindestens einen Deckplatte an das gewünschte Kantenprofil der Schmalfläche sowie der Art des Beschichtungsverfahrens anzupassen.For example, several zones between the bolt and the at least one cover plate can be provided. Thus, in two zones the final adhesive can be used, in a third zone the assembly adhesive. As a result, a large number of design possibilities are given to adapt the bonding of the bolt with the at least one cover plate to the desired edge profile of the narrow surface and the type of coating process.

Besonders vorteilhaft werden also die Anforderungen eines schnellen Abbindens und somit Verklebens des Riegels mit der mindestens einen Deckplatte sowie die erforderliche hohe Wärmebeständigkeit zur Nachbearbeitung der Schmalfläche auf zwei Klebstoffe verteilt. Während der Montageklebstoff schon die erforderliche Verbindung des Riegels zur mindestens einen Deckplatte hergestellt hat, hat der Endklebstoff noch Zeit seine Endfestigkeit zu erreichen. Ist die Endfestigkeit des Endklebstoffs erreicht, so führt seine ausreichende Wärmebeständigkeit dazu, dass der Riegel mit der mindestens einen Deckplatte verbunden bleibt, auch wenn der Montageklebstoff zumindest teilweise durch die beim Nacharbeiten entstehenden Temperaturen aufweicht.Thus, the requirements of rapid setting and thus bonding of the bolt to the at least one cover plate and the required high heat resistance for reworking the narrow surface are distributed particularly advantageously on two adhesives. While the assembly adhesive has already produced the required connection of the bolt to at least one cover plate, the final adhesive still has time to reach its final strength. If the final strength of the final adhesive is reached, its sufficient heat resistance will cause the latch to remain joined to the at least one cover plate, even if the mounting adhesive at least partially softens due to the temperatures encountered during reworking.

Unabhängig von denzuvor beschriebenen Ausgestaltungen des Verfahrensist das technische Problem erfindungsgemäß auch bei einem Verfahren zur Bearbeitung einer Schmalfläche einer Leichtbauplatte, die die zuvor genannten Merkmale aufweist, dadurch gelöst, dass die maximale Bearbeitungstemperatur der Schmalfläche kleiner als die Wärmebeständigkeit des Endklebstoffs ist.Regardless of the above-described embodiments of the method, the technical problem according to the invention is also solved in a method for processing a narrow surface of a lightweight board having the aforementioned features, characterized in that the maximum processing temperature of the narrow area is smaller than the heat resistance of the final adhesive.

Die Erfindung wird im Folgenden anhand spezieller Ausführungsbeispiele und der beiliegenden Zeichnung näher erläutert. In der Zeichnung zeigen

The invention will be explained in more detail below with reference to specific embodiments and the accompanying drawings. In the drawing show

Fig. 1 zeigt eine Leichtbauplatte 1 mit zwei Deckplatten 3, mit einer Mittellage 5, mit einer sich über die beiden Deckplatten 3 und die Mittellage 5 erstreckenden Schmalfläche 7, mit einem im Bereich der Schmalfläche 7 angeordneten Riegel 9 und mit einem den Riegel 9 mit beiden Deckplatten 3 zumindest abschnittsweise verbindenden Montageklebstoff 11. Ein den Riegel 9 mit der oberen Deckplatte 3 abschnittsweise verbindender Endklebstoff 13 ist vorgesehen. Erfindungsgemäß ist die Wärmebeständigkeit des Endklebstoffs 13 größer als die Wärmebeständigkeit des Montageklebstoffs 11. Fig. 1 shows a lightweight board 1 with two cover plates 3, with a middle layer 5, with a extending over the two cover plates 3 and the middle layer 5 narrow surface 7, arranged in the region of the narrow surface 7 bolt 9 and a bolt 9 with two cover plates. 3 at least partially connecting assembly adhesive 11. A the latch 9 with the upper cover plate 3 partially connecting end adhesive 13 is provided. In the present invention, the heat resistance of the final adhesive 13 is greater than the heat resistance of the mounting adhesive 11.

In Fig. 2 ist gezeigt, dass der Montageklebstoff 11 und der Endklebstoff 13 den Riegel 9 abschnittsweise auch mit beiden Deckplatten 3 verbinden kann. In vorteilhafter Weise kann so zunächst durch den Montageklebstoff 11 der Riegel 9 schnell mit den Deckplatten 3 verbunden werden. Bei thermischer Belastung, beispielsweise durch eine im Folgenden erläuterte Nachbearbeitung, kann eine Verbindung des Riegels 9 mit den Deckplatten 3 durch die höhere Wärmebeständigkeit des Endklebstoffs 13 gewährleistet werden, auch wenn die Klebewirkung des Montageklebstoffs 11 aufgrund seiner geringeren Wärmebeständigkeit bereits nachlässt oder vollständig versagt.In Fig. 2 It is shown that the assembly adhesive 11 and the end adhesive 13 can connect the latch 9 sections with both cover plates 3. In an advantageous manner, the bolt 9 can thus be quickly connected to the cover plates 3 by the assembly adhesive 11. For thermal stress, for example by one explained below Post-processing, a connection of the bolt 9 with the cover plates 3 can be ensured by the higher heat resistance of the final adhesive 13, even if the adhesive effect of the assembly adhesive 11 already deteriorates or completely fails due to its lower heat resistance.

Wie im Folgenden erläutert wird, ist die erfindungsgemäße Ausführung besonders vorteilhaft bei einer Leichtbauplatte 1 anzuwenden, die im Bereich der Schmalfläche 7 nachbearbeitet werden soll.As will be explained below, the embodiment according to the invention is particularly advantageous for use with a lightweight board 1 which is to be reworked in the region of the narrow surface 7.

Fig. 3 zeigt eine Leichtbauplatte 1, die im Bereich der Schmalfläche 7 nachbearbeitet werden soll. Die Deckplatten 3 weisen eine zusätzliche Laminatschicht 15 auf. Dabei kann mindestens eine der Laminatschichten 15 einen Überstand 17 aufweisen, der in Fig. 3 gestrichelt dargestellt ist. Ein solcher Überstand 17 wird insbesondere beim Postforming verwendet, wie weiter unten erläutert. Der Montageklebstoff 11 ist in dieser Ausführungsform lediglich in einem kleinen Bereich vorgesehen. Auf beiden Seiten des Montageklebstoffs 11 ist der Endklebstoff 13 zum Verbinden des Riegels 9 mit den beiden Deckplatten 3 vorgesehen. Fig. 3 shows a lightweight board 1, which is to be reworked in the region of the narrow surface 7. The cover plates 3 have an additional laminate layer 15. In this case, at least one of the laminate layers 15 may have a projection 17, which in Fig. 3 is shown in dashed lines. Such a projection 17 is used in particular in postforming, as explained below. The mounting adhesive 11 is provided in this embodiment only in a small area. On both sides of the mounting adhesive 11, the end adhesive 13 is provided for connecting the bolt 9 with the two cover plates 3.

Fig. 4 zeigt die Leichtbauplatte 1 aus Fig. 3, deren Schmalfläche 7 und Überstand 17 durch Postforming nachbearbeitet worden sind. Dafür wurde zunächst die Schmalfläche 17 im Bereich 19, beispielsweise durch Fräsen, bearbeitet. Erst nach dem Fräsen wird dann die Laminatschicht 15 mit dem Überstand 17 auf die Deckplatte 3 aufgebracht. Fig. 4 shows the lightweight panel 1 Fig. 3 whose narrow surface 7 and supernatant 17 have been post-processed by postforming. Initially, the narrow surface 17 in the region 19, for example by milling, was processed. Only after milling then the laminate layer 15 is applied to the supernatant 17 on the cover plate 3.

Durch das Fräsen wird, wie in Fig. 4 gezeigt, nur ein Teil des Endklebstoffs 13 entfernt. Die Verbindung des Riegels 9 zu den beiden Deckplatten 3 bleibt, aufgrund der hohen Wärmebeständigkeit des Endklebstoffs 13, trotz der durch die Nachbearbeitung entstehenden Temperaturen erhalten. Daran anschließend wird der Überstand 17 auf die gefräste Fläche der Schmalfläche 7 durch Druck und Wärme aufgebracht. Wiederum reicht die Wärmebeständigkeit des Endklebstoffs 13 aus, um eine Verbindung des Riegels 9 zu den Deckplatten 3 beizubehalten.By milling, as in Fig. 4 shown, only a portion of the final adhesive 13 removed. The connection of the bolt 9 to the two cover plates 3 remains due to the high heat resistance of the final adhesive 13, despite the temperatures resulting from the post-processing obtained. Subsequently, the supernatant 17 is applied to the milled surface of the narrow surface 7 by pressure and heat. Again, the heat resistance of the final adhesive 13 is sufficient to maintain bonding of the latch 9 to the cover plates 3.

Fig. 5 zeigt eine weitere Form der Nachbearbeitung im Bereich der Schmalfläche 7 der in Fig. 3 gezeigten Leichtbauplatte 1. Im in Fig. 5 gezeigten Ausführungsbeispiel wurde der Bereich der Schmalfläche 7 durch Softforming bearbeitet. Wiederum ist die Leichtbauplatte im Bereich 19 durch Fräsen bearbeitet und der Endklebstoff 13 wird nur teilweise bei der Nachbearbeitung entfernt. Auch hier bleibt während der Nachbearbeitung die Klebkraft des Endklebstoffes erhalten, so dass keine Fehler bei der Nachbearbeitung der Leichtbauplatte 1 auftreten. Fig. 5 shows a further form of finishing in the area of the narrow surface 7 of Fig. 3 shown lightweight panel 1. Im in Fig. 5 In the embodiment shown, the area of the narrow surface 7 was processed by soft-forming. Again, the lightweight panel is processed in the area 19 by milling and the final adhesive 13 is only partially removed during post-processing. Again, the bond strength of the final adhesive is maintained during post-processing, so that no errors in the post-processing of the lightweight board 1 occur.

Im Unterschied zum in Fig. 4 gezeigten Ausführungsbeispiel ist die Beschichtung 21 der profilierten Schmalfläche 7 jedoch, wie beim Softforming üblich, gesondert von der Beschichtung 15 der Deckplatten 3 ausgeführt.Unlike in Fig. 4 As shown in the embodiment shown, the coating 21 of the profiled narrow surface 7, however, as customary in softforming, carried out separately from the coating 15 of the cover plates 3.
