"Verfahren zum Herstellen eines Dachelementes""Method for producing a roof element"
Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen miteinander verbindbarer Dachelemente, bei dem zwischen zwei Metallblechen eine Wärmedämmung, wie z.B. Polyurethan, zu Schaum verarbeitet oder eingeklebt wird.The present invention relates to a method of manufacture Roof elements that can be connected to one another, in which a thermal insulation such as polyurethane is used to form foam between two metal sheets processed or glued.
Der Nachteil bei derartigen bekannten Herstellungsverfahren besteht darin, daß das Ablängen des bereits profilierten oberen Bleches nach dem sog. Guillotineprinzip schwierig ist. Das Ablängen muß in zwei Schritten erfolgen. Wenn man verschäumbare Dämmittel, wie z.B. Polyurethan, verwendet, entstehen an den Längsseiten des Elementes schwer zu beherrschende Ausflußsteilen. Das Wärmedämmaterial wird nämlich in den Bereich der maschinell herzustellenden Verbindungszonen oder -fugen verdrängt und ist nur schwer zu entfernen. Infolge des Falzes für das maschinelle Verbinden der Elemente nimmt die Höhe je-.iesThe disadvantage with such known manufacturing processes is in that it is difficult to cut the already profiled upper sheet to length according to the so-called guillotine principle. The cutting to length must be done in two steps. If foamable insulating materials such as polyurethane are used, the Long sides of the element difficult to control outflow parts. The thermal insulation material is namely in the area of Mechanically produced connection zones or joints are displaced and are difficult to remove. As a result of the fold for the mechanical connection of the elements, the height increases
Elementes um 3C ~m cu, wodurch in den Frcduktionsschritten effektiver Preßraum in der Form verlorengeht. Wenn Dachc-lemente auf einer sog. kontinuierlichen Gußstraße gefertigt werden, muß man das obere und untere Blech des Elementes in endgültig profilierter Form vorgefertigt in die Maschine einführen. Hierdurct steigt der Raumanspruch für die Apparatur in der Längsrichtung, und es führt zu schwierigen technischen Lösungen.Element by 3C ~ m cu, whereby in the production steps effective press space in the mold is lost. If roof elements are manufactured on a so-called continuous casting line, the upper and lower sheet metal of the element must be finally profiled Introduce the prefabricated form into the machine. Here you go the space required for the apparatus in the longitudinal direction increases, and it leads to difficult technical solutions.
Die vorliegende Erfindung bezweckt die Abhilfe der obenstehend angesprochenen Nachteile.The present invention aims to remedy the above-mentioned disadvantages.
Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, daß anschließend an die Befestigung des Dämmaterials mittels einer Rollenformtechnik an den Rändern des oberen Bleches die zum maschinellen Verbinden erforderlichen Falze profiliert werden.The method according to the invention is characterized in that then to the attachment of the insulation material by means of a roll molding technique on the edges of the upper sheet metal machine connections required seams are profiled.
Man kann vermöge der Erfindung das obere Blech in ebenem Zustanc mit herkömmlichen Blechscheren abschneiden. Das ebene obere Blech läßt sich äußerst dicht in die Form einsetzen, womit schädliche Leckflüsse nicht entstehen können. Der für die Bildung der Fuge für die maschinelle Verbindung früher benötigte Raum kann jetzt effektiv ausgenutzt werden. Man kann in einem Preßfach statt vier fünf Elemente pressen. Bei einer kontinuierlichen Gußstraße wird das obere Blech von einer Rolle h/>r der Gußstraße zugeführt, womit die Herstellung der Herstellung eines einfachen Dämmelementes ähnlich wird.By virtue of the invention, the upper sheet can be cut off in a flat state using conventional sheet metal snips. The level upper one Sheet metal can be used extremely tightly in the mold, so that harmful leakage flows cannot arise. The one for the Formation of the joint for the mechanical connection space previously required can now be used effectively. One can in one Press compartment press five elements instead of four. With a continuous In the casting line, the upper sheet is h /> r of a roll Casting line supplied, with which the manufacture of manufacture a simple insulation element is similar.
Die Erfindung wird nachstehend an Hand eines Beispieles mit Hinweis auf die beiliegende Zeichnung erläutert.The invention is explained below using an example with reference to the accompanying drawing.
Die Figuren 1 bis 4 zeigen die Profilierung der Ränder des oberen Bleches des Dachelementes in verschiedenen Arbeitsstufen beim Herstellen eines Dachelementes mit Polyurethandämmung. Figures 1 to 4 show the profiling of the edges of the Upper sheet of the roof element in different work stages when producing a roof element with polyurethane insulation.
Im Dachelement-Herstellungsprozeß wird Polyurethan 1 im Raum zwischen dem oberen und dem unteren Blech 2,3 verschäumt. Erst nach erfolgter Verschäumung des Polyurethans 1 werden mittels der Rollenverformungstechnik an den Rändern des oberen BlechesIn the roof element manufacturing process, polyurethane 1 is foamed in the space between the upper and lower sheet 2,3. First After the polyurethane 1 has been foamed, the roller deformation technique is used to apply it to the edges of the upper sheet
2 die zur maschinellen Verbindung der Elemente erforderlichen Falze 4,5 profiliert. Das Element gemäß Fig. 1 wird auf einer Rollenbahn abgelegt, die auf einander gegenüberliegenden Seiten mit Rollen ausgerüstete Profilierstationen aufweist. Fig. 2 und2 necessary for the mechanical connection of the elements Seams 4.5 profiled. The element according to FIG. 1 is on a Filed roller conveyor, which has profiling stations equipped with rollers on opposite sides. Fig. 2 and
3 lassen erkennen, wie das Randprofilieren fortschreitet, d.h. wie die Falze für die maschinelle Verbindung der Elemente entstehen. Das endgültige Produkt ist in Fig. 4 gezeigt.3 show how the edge profiling progresses, i.e. how the folds for the mechanical connection of the elements are created. The final product is shown in FIG.
