Abstract

Parallel and transverse running ribs forming edge seals or supporting core reinforcing ribs with a single or double material thickness are produced in a hot pressing stage during which the panel layers(22,23,24) are themselves compressed. Panels are cooled following the hot pressing stage. Deformation of the upper(22) or lower(24) facing layer to form ribs on the various panel edges occurs prior to compression of the facing layers and core(23). The first single or double rib to be deformed is in the middle of the plate in either longitudinal or transverse direction. Ribs on both sides of the first rib are then produced progressively towards the outer edges. Panel edge sealing ribs are then formed on the two opposing edges. Ribs transverse to the first set are then formed again starting from the panel center. All layers are then compressed to consolidate the panel. A release film layer(21) on both outer facing layers is deformed with the latter layers. Release film may have a negative raised structure according to the panel being produced. Forming tools for the edge seals have a depth equal to the panel thickness less the thickness of facing layers and protective films. Edge sealing tools are at the same or higher temperature than the press platens. Tools for producing ribs from the center outwards are tongue shaped while the tools for edge closure may or may not have a tongue shape. The initial sizes of the facing layers takes account of the panel size and the depths of all ribs in the final structure. All panel surfaces and edges have the same thickness and material structure. Forming tools can operate from above and below panels. Repeated forming operations from the other side of a panel can produce double thickness edge seals. Edge seals can also be produced by simultaneously forming facing layers to the mid-thickness point. Types of sealing include ribs, double ribs, rounded edges, grooves, tongues or a combination of these. Each sealing stage compresses the core between the facing layers so that a homogeneous stable material is produced. Independent claims are also included for: (a) a lightweight panel with two or four sealed edges; (b) a scaffold board with or without hanging device; and (c) a floor panel of thermoplastic plastic.

Description

Mit der Deutschen Patentanmeldung 102 088 29.2 ist ein thermolastisches Rollverformungsverfahren beschrieben, mit dem bereits fertig auf ihre endgültige Abmessung thermoplastisch verpreßte Leichtbauplatten rationalle im Durchlaufverfahren ihre Seitenabschlüsse in verschiedenen Varianten erhalten sollen. In der Patentanmeldung WO 01/19604 A1 ist die handwerkliche Art der Herstellung dargestellt. With the German patent application 102 088 29.2 is a thermoplastic Roll forming process described with which is already finished to its final thermoplastic dimension pressed lightweight boards rationally in the continuous process should receive different variants. In patent application WO 01/19604 A1 the artisanal way of manufacturing illustrated.

Die erfindungsgemäße Herstellungart zeigt nun, wie im Rahmen eines einzigen, gestaffelt ablaufenden Preßvorganges mit einer Platten-Heißpresse aus großflächig ausgelegtem, thermoplastischem Deckschicht- und Stützkern-Material Leichtbauplatten verschiedener Art, wie zum Beispiel einfache Sandwichplatten, Gerüstplatten, Schalungsplatten, Bodenplatten und andere Paneele mit Kantenverschluß und anderen Randabschlußformen sowohl einzeln als auch in mehreren Plattenreihen neben- und hintereinander, auch in verschiedenen Breiten und Abmessungen, heißgepreßt und anschließend gekühlt paßgenau hergestellt werden können. The type of manufacture according to the invention now shows, as in a single, staggered ongoing pressing process with a hot plate press made of large, thermoplastic top layer and support core material lightweight boards of various types, such as simple sandwich panels, scaffolding panels, formwork panels, floor panels and other panels with edge closure and other edge finishing shapes both individually as well as in several rows of plates next to and behind each other, also in different widths and dimensions, hot pressed and then made to fit exactly cooled can.

Der Vorgang ist der, daß zuerst die gesamte vorgesehene Preßfläche mit einer Trennfolie, die sich dem ablaufenden Preßverfahren eng anpaßt und wenn erforderlich auch die der unteren Außenseite des Preßstücks vorgesehene Struktur im Negativ aufweist, ausgelegt wird. Danach folgt die Auslegung der Fläche mit dem für die untere Deckschicht der Platte vorgesehenen Platten- oder Vliesmaterial, wenn erforderlich faserarmiert. Der nächste Schritt ist die Auslegung mit Stützkernmaterial in der späteren Stützkernhöhe einschließlich des oben und unten abzuschmelzenden Materialanteils und danach folgt das für die obere Deckschicht und das für die äußere Seite des Kantenverschlusses notwendige Platten- oder Vliesmaterial, das größenmäßig die Fläche der Platte zuzüglich der Kanten- und Steghöhen der späteren Einzelplatten umfassen muß, das dann am Schluß mit der oberen gleich großen Trennfolie, die gegebenenfalls zur Platte hin die Struktur der Oberseite des Preßstücks im Negativ aufweist, abgedeckt wird. The process is that first the entire intended press surface with a release film, the adapts closely to the pressing process in progress and, if necessary, also that of the lower ones Has provided the outside of the press structure provided in the negative. After that follows the layout of the surface with that provided for the lower cover layer of the plate Sheet or fleece material, fiber-reinforced if necessary. The next step is interpretation with support core material in the later support core height including the top and bottom portion of material to be melted and then follows for the top cover layer and for the outer side of the edge fastener necessary plate or fleece material, the in terms of size, the area of the panel plus the edge and web heights of the later individual panels must include that then at the end with the upper equal separation film, the optionally has the structure of the top of the pressing piece in the negative, covered becomes.

Danach beginnt der Ablauf des Preßvorganges so, daß zuerst die Heißverformung der Deckschicht und der darunterliegenden Stützkernschicht in der Mitte der Presse in Längs- oder Querrichtung zu einem Steg oder Doppelsteg und in der Folge zeitverschoben die beiden links und rechts davon liegenden Deckschichten und darunterliegenden Stützkernschichten gleichermaßen verformt werden. Weiter zeitversetzt erfolgen die nächsten zum Pressenrand hin erforderlichen Verformungen solange, bis der letzte Kantenverschluß an beiden Seiten erreicht ist. Then the pressing process begins so that first the hot deformation of the Top layer and the underlying core layer in the middle of the press in longitudinal or Transverse direction to a footbridge or double footbridge and subsequently the two on the left and to the right of it cover layers and underlying support core layers be deformed equally. The next ones are delayed towards the press edge necessary deformations until the last edge seal on both sides is reached.

Nach diesen Vorgängen erfolgt von der Mitte der Presse aus ein gleicher Ablauf in Querrichtung solange, bis das gesamte Pressgut nach den vorher festgelegten Vorgaben geteilt ist. Erst danach erfolgt die Heißverpressung der gesamten oberen und unteren Plattenfläche. Durch die zeitversetzte Verformung für die Plattenteilung passen sich die aufgelegten Deckschichten samt den Trennfolien automatisch der sich verändernden Plattenform auch im Kantenbereich jeweils bis zum Endpunkt der Verformung an und verbleiben als heißes Formteil an dieser Stelle. After these processes, the same process in the transverse direction takes place from the center of the press until the entire pressed material is divided according to the previously specified specifications. First the entire upper and lower plate surface is then hot-pressed. Through the time-shifted deformation for the plate division, the overlay layers fit together the separating foils automatically the changing plate shape also in the edge area in each case to the end point of the deformation and remain as a hot molded part at this point.

Nach dem anschließenden Kühlvorgang werden die in die Platte eingeführten Preßstege (-werkzeuge) und die Trennfolie entfernt und die durch den Druck des Preßwerkzeugs weitgehend getrennten Plattenteile aus der Presse entfernt und diese erneut belegt. Damit die einzelnen Stege und Kanten zeitversetzt verformt werden können, müssen die Preßstege thermisch mit den Heißplatten der Presse verbunden und gefedert gelagert sein. Bei der Herstellung doppelter Stege darf die Trennfolie zwischen den beiden Stegteilen dann nicht wirksam werden, wenn diese verbunden werden sollen. After the subsequent cooling process, the press ridges inserted into the plate (tools) and the release film removed and largely by the pressure of the press tool separated plate parts removed from the press and re-occupied. So that the individual If the webs and edges can be deformed at different times, the press webs must be thermally included be connected to the hot plates of the press and spring loaded. When making double The separating film between the two web parts must not become effective if these should be connected.

Je nach der Art des Kantenverschlusses kann das Preßwerkzeug auch eine andere Temperatur wie die Heißpressplatte der Plattenpresse aufweisen. Depending on the type of edge seal, the pressing tool can also have a different temperature like the hot press plate of the plate press.

Es sind Pressverbindungen auf volle Höhe der Platte, auch von der oberen und unteren Seite, möglich, aber auch von beiden Seiten (oben und unten und sich in der Mitte treffend). There are press connections at full height of the plate, also from the top and bottom, possible, but also from both sides (above and below and meeting in the middle).

Gleichzeitig mit der Gesamtverpressung oder aber auch mit den einzelnen Kantenpreßvorgängen ist es auch möglich, lochnietartige Lochungen der Platte mit entsprechenden Werkzeugen an den vorher bestimmten Stellen anzubringen. Auch ist es möglich, die Kantenverformung als Rundnut, Nut oder anders geformte Aussparung oder Paßform herzustellen, so daß in einem Gesamtpreßgang gefertigte Produkte wie Bodenplatten, Gerüstbretter mit Armatur, genutete und mit Feder versehene Paneele die Presse verlassen. Simultaneously with the total pressing or also with the individual Edge pressing processes, it is also possible to perforate the plate with corresponding rivet holes To attach tools at the predetermined locations. It is also possible that To produce edge deformation as a round groove, groove or other shaped recess or fit, so that in a total press run manufactured products such as floor slabs, scaffolding boards with Valve, grooved and spring-loaded panels leave the press.
