Abstract

The external cladding system uses aluminium sheet on walls of wood or similar material, partic. in the manufacture of caravans. In a single, and pref. continuous operation, an intermediate coating of absorbent material is applied to one side of the aluminium sheet, after which the outside of the wall to be clad is coated with adhesive. The sheet is then applied to the wall with its coated side towards the latter, and the two are hot-pressed together. An adhesive can be used to secure the absorbent material to the sheet. The material can be applied only to part of the sheet surface, and can comprise particles of wood, a prefabricated strip of material, or foam.

Description

Die Erfindung betrifft ein Verfahren zur AußenverkleidungThe invention relates to a method for exterior cladding

von Wandelementen aus Holz oder holzartigen Werkstoffen mit Aluminiumblech, insbesondere für die Herstellung von Wohnwagen.of wall elements made of wood or wood-like materials with aluminum sheet, especially for the manufacture of caravans.

Bei Wohnwagen ist es bekannt und weithin üblich, die Wände in einer leimgebundenen Holzverbund-Bauweise herzustellen.In the case of caravans, it is known and widely used to have the walls in one to produce glue-bonded wood composite construction.

Auf ein Holzgerippe werden ein- oder zweiseitig Sperrholzplatten, Spanplatten oder dgl. aufgeleimt. Die Zwischenräume zwischen den Holzverstrebungen werden meist mit ebenfalls verleimten plattenförmigen Einlagen aus einem Schaumstoff ausgefüllt. Das Beleimen der Gerippe und Plattenwerkstoffe erfolgt mit Hilfe von Walzenauftragsmaschinen. Verwendete Leime sind Weißleim auf PVA- oder PVC-Basis oder z.B. auch Harnstoffleime. Die zusammengefügten Teile werden in einer beispielsweise im 7-Minuten-Takt arbeitenden Heizpresse zusammengepreßt und anschließend, d.h. nachdem sie sich verbunden haben, in einer automatischen Fräsvorriciltuna mit einer bestimmten Außenkontur und/oder Ausnehmungen versehen.Plywood panels are placed on one or both sides of a wooden framework, Chipboard or the like. Glued on. The spaces between the wooden struts are usually also glued with plate-shaped inserts made of a foam filled out. The framework and panel materials are glued with the help of Roller application machines. The glues used are white glue based on PVA or PVC or, for example, urea glue. The assembled parts are in an example pressed together in a 7-minute cycle and then, i.e. after they have connected, in an automatic milling process with a provided certain outer contour and / or recesses.

Sodann werden bei dem bekannten Verfahren die Wandelemente am Boden eines Fahrgestells befestigt. Erst in dieser vertikalen Stellung der Wandelemente werden diese mit einem thermoplastischen Kleber bespritzt und schließlich die Außenhaut aus Aluminium von Hand angedrückt und damit angeklebt.Then, in the known method, the wall elements are on the floor attached to a chassis. Only in this vertical position of the wall elements these are sprayed with a thermoplastic adhesive and finally the outer skin made of aluminum pressed on by hand and glued on.

Danach werden noch die Konturen des Aluminiumblechs nachgefräst.Then the contours of the aluminum sheet are milled.

Diese bekannte Verklebung der Aluminiumaußenhaut haftet jedoch ungenügend. In der heißen Sonne wird der Spritzkleber weich.However, this known gluing of the aluminum outer skin does not adhere adequately. The spray adhesive softens in the hot sun.

Das Aluminiumblech wellt sich. Abgesehen davon ist aber auch das vom Herstellen der Wandelemente zeitlich und örtlich getrennte Aufbringen der Aluminiumaußenhaut fertigungstechnisch unbefriedigend. Diese Trennung ist aber bislang unumgänglich, da alle zur Direktverklebung des AluminiumblechS geeigneten Kleber explosionsgefährlich sind und besondere Arbeitsschutzvorrichtungen verlangen. Vor allem aber paßt dieser Klebevorgang mit dem vom Leim und von der Presse bestimmten Arbeitstakt an der Fertigungsstraße für Wandelemente nicht zusammen.The aluminum sheet is corrugated. Apart from that, this is also from Manufacture of the wall elements in a temporally and spatially separate application of the aluminum outer skin unsatisfactory from a manufacturing point of view. However, this separation has so far been inevitable, as all adhesives suitable for direct bonding of the aluminum sheet are explosive and require special occupational safety devices. But above all, this one fits Gluing process with the work cycle determined by the glue and the press on the production line for wall elements not together.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem es möglich ist, komplette aluminiumverkleidete Wandelemente mit den bislang vorhandenen Einrichtungen in einer einzigen Fertigungsstraße herzustellen.The invention is based on the object of specifying a method with which it is possible to combine complete aluminum-clad wall elements with the previously existing facilities in a single production line.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Aluminiumblech in einem eigenen, vorzugsweise kontinuierlichen Arbeitsverfahren an einer Seite mit einer saugfähigen Zwischenschicht versehen wird, daß sodann das zu verkleidende Wandelement oder seine an der Außenseite liegenden Teile an der Außenseite beleimt werden, und daß schließlich das beschichtete Aluminiumblech mit der Zwischenschicht auf das so vorbereitete Wandelement oder seine Teile gelegt und in einer Heizpresse aufgepreßt wird.This object is achieved according to the invention in that the aluminum sheet in a separate, preferably continuous work process on one side is provided with an absorbent intermediate layer, that then the to be disguised Wall element or its parts lying on the outside are glued on the outside and that finally the coated aluminum sheet with the intermediate layer placed on the prepared wall element or its parts and placed in a heating press is pressed on.

Saugfähig muß die erwähnte Zwischenschicht sein, um, wie Holz, Spanplatten oder dergleichen, den Leim in die Oberfläche eindringen zu lassen und dadurch erst eine Verleimung im eigentlichen Sinne des Wortes zu ermöglichen. Der Vorschlag läuft darauf hinaus, das Aufbringen der Zwischenschicht zum Aluminiumwalzwerk hin zu verlegen. Dort kann die saugfähige Zwischenschicht mittels eines geigneten Klebers am laufenden Band aufgebracht und dann das beschichtete Aluminiumblech als Coil beim Verwender angeliefert werden. Als Kleber eignet sich z.B. ein Fabrikat auf Epoxydharz- oder Polyurethan-Basis, das auch aus zwei oder mehr Komponenten gemischt sein kann.The mentioned intermediate layer must be absorbent in order, like wood, Chipboard or the like, to let the glue penetrate into the surface and only thereby to enable gluing in the true sense of the word. The proposal is running on moving the application of the intermediate layer to the aluminum rolling mill. There, the absorbent intermediate layer can be kept on the go by means of a suitable adhesive Tape applied and then the coated aluminum sheet as a coil at the user to be delivered. A product on epoxy resin or Polyurethane base, which can also be mixed from two or more components.

Das Wandelement wird im gleichen Arbeitstakt und mit den gleichen maschinellen Einrichtungen wie bisher zur Verleimung zusammengefügt. Zusätzlich wird jedoch die Außenseite beleimt und das Aluminiumblech mit der Zwischenschicht zum Leim gekehrt aufgelegt. Die so aufgeschichtete Charge wird in der Heizpresse verpreßt, wobei sich gleichzeitig die tragenden Bestandteile des Wandelements untereinander und über die den Leim aufnehmende Zwischenschicht mit dem Aluminiumblech verbinden. Die erreichte Endhaftung ist wesentlich besser und auf jeden Fall sonnenfest. Zudem spart man sich das bisher notwendige Nachfräsen der Konturen der Aluminiumhaut. Dies übernimmt vielmehr die zu Anfang erwähnte Fräsvorrichtung.The wall element is made in the same work cycle and with the same mechanical devices joined together for gluing as before. Additionally however, the outside is glued and the aluminum sheet with the intermediate layer Applied upside down to the glue. The batch stacked in this way is placed in the heating press pressed, at the same time the load-bearing components of the wall element with one another and connect to the aluminum sheet via the intermediate layer that absorbs the glue. The final adhesion achieved is much better and definitely sun-proof. In addition You save yourself the previously necessary re-milling of the contours of the aluminum skin. Rather, this is done by the milling device mentioned at the beginning.

Unter bestimmten Umständen kann es genügen, wenn die saugfähige zwischenschicht nicht die ganze Aluminiumoberfläche bedeckt, sondern nur stellenweise, beispielsweise streifenförmig oder punktförmig aufgebracht ist. Die Zwischenschicht kann aus einzelnen Holzpartikeln, insbesondere Sägemehl, bestehen. Sie kann aber auch ein in aufrollbaren, großflächigen Bahnen vorgefertigter Werkstoff sein, worunter zu verstehen ist: Papier, Pappe, Vlies, insbesondere Glasvlies, Filz.Under certain circumstances it can be sufficient if the absorbent intermediate layer does not cover the entire aluminum surface, but only in places, for example strip-shaped or is applied punctiformly. The intermediate layer can consist of individual wood particles, especially sawdust. But she can also be a material prefabricated in roll-up, large-area strips, including to be understood is: paper, cardboard, fleece, in particular glass fleece, felt.

Textilgewebe, Schaumstoff oder dergleichen. Schließlich kann die Zwischenschicht auch aufgeschäumt sein als Schaumgummi oder Kunststoffschaum, wobei der Schaum möglichst offenporig sein sollte.Textile fabric, foam or the like. Finally, the intermediate layer also be foamed as foam rubber or plastic foam, the foam as possible should be open-pored.

Außer für Fahrzeuge auf dem Wohnwagensektor, insbesondere Wohnanhänger und Reisemobile, eignet sich das Verfahren selbstverständlich auch für Verkaufsstände, Baracken und ähnliche transportable UnterkUnfte, deren Wandelemente in ähnlicher Weise hergestellt und außen witterungsfest verkleidet sind.Except for vehicles in the caravan sector, especially caravans and motorhomes, the process is of course also suitable for sales stands, Barracks and similar transportable accommodations, the wall elements of which are similar Manufactured in a manner that is weatherproof on the outside.

Ferner erfaßt die Erfindung auch Außenhautverkleidungen aus einem anderen Werkstoff als Aluminium, beispielweise einem anderen, nicht rostenden Metall oder einem Kunststoff.Furthermore, the invention also includes outer skin panels from one a material other than aluminum, for example a different, non-rusting metal or a plastic.
