Es sind auf dem Markt bereits transparente Platten, insbesondere aus Polymethylmetacrylat oder arideren Materialien mit einer doppelten Wand vorhanden,bei denen die beiden Außenwände durch eine Reihe senkrechter , gleichmäßig beabstandeter Trennwände parallel zueinander gehalten sind, die eine Reihe benachbarter Zellen von im wesentlihen rechteckigem Querschnitt bilden.There are already transparent plates on the market, in particular made of polymethyl methacrylate or other materials with a double wall, in which the two outer walls are separated by a series of vertical, evenly spaced partitions are held parallel to each other, which form a series of adjacent cells of wesentlihen rectangular cross-section.
Diese Arten doppelwandiger Platten mit durch lotrecht zu den gegenüberliegenden Wänden verlaufende Trennwände gebildeten Zellen bieten in der Praxis kein hohes Maß an thermischer Isolierung, da diese Trennwände, die lotrecht zu den Wänden der Platte verlaufen,These types of double-walled panels with cells formed by partitions perpendicular to the opposing walls do not offer a high level of thermal insulation in practice, as these partitions, which are perpendicular to the walls of the panel,
niemals eine Unterbrechungs- oder Unterteilungseinrichtung für die gegenüberliegenden Wände mitBezug aufeinander darstellen; tatsächlich sehen die aufeinander folgenden Zellen in ihrem Innern keine Mittel vor, die geeignet wären zur Isolierung oder Trennung der gegenüberliegenden Wände der Platte, soweit die Wärmpnbertragung betroffen ist.never an interrupting or dividing device for the represent opposing walls with respect to each other; actually see the successive cells inside them no means are provided which would be suitable for isolating or separating the opposing walls of the plate, insofar as heat transfer is concerned is affected.
Im Gegensatz dazu besteht die Aufgabe der Erfindung darin, eine dcppelwandige Platte von cellularem Charakter zu schaffen, die insofern verbessert ist, als sie die beiden gegenüberliegenden Wände durch eine besondere Gestaltung der Zellen thermisch zwischeneinander isoliert, um ^o eine doppelwaniige Platte mit hoher Isolierwirkung zu erzielen, ohne dabei im Falle von transparenten Platten deren Lichtenergiedurchlässigkeitskoeffizienten negativ zu beeinflussen.In contrast, the object of the invention is to provide a To create a double-walled panel of cellular character, improved in that it is opposite to the two Walls are thermally insulated between each other by a special design of the cells, around ^ o a double-walled plate with a high insulating effect without, in the case of transparent panels, their light energy transmission coefficient being negative to influence.

Mit Bezug auf alle oben genannten Figuren besteht die cellulare Platte gemäß der Erfindung auszwei Wänden 1 und 2, die durch eine durchgehende Trennteilungsplatte 3 auf Abstand voneinander und parallel zueinander gehalten v/erden, die in den Figuren 1, 2 und 3 eine Zick-Zack-Form zeigt, d. h., die Gestalt einer unterbrochenen Linie mit geneigten Seiten hat,-während in Fig. 4 die Trennteilung eine wellenförmige Ebene hat, bei der die gekrümmten Seiten 4'alle auf derselben Seite liegen und denselben Biegeradius haben.With reference to all of the above figures, there is the cellular Plate according to the invention composed of two walls 1 and 2 which held at a distance from one another and parallel to one another by a continuous partition plate 3, which are in the Figures 1, 2 and 3 show a zigzag shape; that is, has the shape of a broken line with sloping sides, -during in Fig. 4 the partition has an undulating plane in which the curved sides 4 'are all on the same Side and have the same bending radius.

der sich gegenüberliegenden Wände 1 und 2 bestreicht. Der Neigungswinkel cc zwischen den abfallenden Seiten der Trennteilung und der Ebene der Platten kann praktisch zwischdii 30 und 60° schwanken. In Fig. 2 zeigt der Winkel oO einen Winkel von 30° an, gebildet zwischen den Seiten der Teilung mit den Wänden, währendcL' eino Winkelneigung von 45° zeigt.the opposite walls 1 and 2 coated. The angle of inclination cc between the sloping sides of the partition and the plane of the plates can practically be between 30 and 60 ° vary. In Fig. 2, the angle oO shows an angle of 30 ° formed between the sides of the division with the walls, while cL 'shows an angular inclination of 45 °.
Zwischen den einzelnen abfallenden Seiten der Trennteilung und den gegenüberliegenden T/änden 1 und 2 wird somit eine Reihe benachbarter Zellen 5, 6, 7, 8, usw. gebildet, welche Strecken der Wand 1 von entsprechenden Strecken der darunter liegenden Wand 2 thermisch isolieren (d. h. thermisch voneinander trennen). Tatsächlich trennt jedes Paar Zellen, wie beispielsweise die Zellen 7 und 8, die sich als den Wandstrecken 1a, 2a benachbart herausstellen, die zwei gegenüberliegenden Strecken der Wand, da die Zellen 7 bis 8 selbst durch eine geneigte oder abfallende Seite der Trennteilung voneinander getrennt werden.A row is thus created between the individual sloping sides of the partition and the opposing T / ands 1 and 2 adjacent cells 5, 6, 7, 8, etc. formed, which stretches of the wall 1 from corresponding stretches of the underlying Thermally isolate wall 2 (i.e. thermally separate it from one another). In fact, each pair separates cells such as the Cells 7 and 8, which turn out to be adjacent to the wall sections 1a, 2a, the two opposite sections of the wall, since the cells 7 to 8 themselves are separated from one another by an inclined or sloping side of the partition.
Auch im Falle der Trennteilung mit gebogenen Seiten (Fig. 4) isolieren die benachbarten Zellen 7a bis 8a die entsprechenden Strecken der gegenüberliegenden Wände thermisch voneinander, da sie durch eine gekrümmte Seite der Teilung getrennt sind.Even in the case of the separation division with curved sides (FIG. 4), the neighboring cells 7a to 8a isolate the corresponding ones Stretch the opposing walls thermally from one another as they are separated by a curved side of the partition.
In der Praxis hat sich herausgestellt, daß im Falle doppelwandiger Platten mit einer Trennteilung mit gebogenen Seiten, wie in Fig. 4 gezeigt, zur Erzielung der bestmöglichen Isolierwirkung zwischen den gegenüberliegenden Wänden der Krüm-In practice it has been found that in the case of double-walled Panels with a partition with curved sides, as shown in Fig. 4, to achieve the best possible insulating effect between the opposite walls of the

Der Zusammenhang der Trennteilung 3 (oder 4), welche die thermische Isoliert'*!? einer Wand von der anderen zuläßt (da die benachbarten fellen durch eine Seite der Trennteilung selbst voneinander getrennt sind), macht die so erzielte doppelwandige Platte insbesondere geeignet znm Heizen von Gewächshäusern und dergleichen. Tatsächlich erzielt man durch Hindurchführen eines heißen Strömungsmitteln durch die unteren Zellen (z. B. durch die Zellen 5, 6, 7 usw.) eine Erwärmung praktisch nur der unteren Wand 2, während die obere Wand infolge des Vorhandenseins der benachbarten Zellen 8 und 9 (Fig. 2 bis 3), wo keine Umwälzung heißen Strömungsmittels stattfindet, thermisch-isoliert bleibt.The connection of the separation division 3 (or 4), which the thermal Isolated'*!? one wall from the other (since the neighboring walls are separated from one another by one side of the partition itself are separated), makes the double-walled plate obtained in this way particularly suitable for heating greenhouses and the like. Indeed, by passing a hot fluid through the lower cells (e.g., through cells 5, 6, 7 etc.) heating practically only the lower wall 2, while the upper wall due to the presence of the adjacent cells 8 and 9 (Fig. 2 to 3), where no circulation of hot fluid takes place, remains thermally insulated.
Die besten Ergebnisse, soweit die thermische Isolierung der gegenüberliegenden Wände betroffen ist, werden praktisch erzielt mit der doppelwandigen Platte nach Fig. 4, d. h. mit gegenüberliegenden Wänden, die durch eine ununterbrochene Trennwand mit gebogenen Seiten voneinander auf Abstand gehalten sind.The best results, as far as the thermal insulation of the opposing walls is concerned, are obtained in practice with the double-walled plate according to FIG. 4, d. H. with opposite walls by an uninterrupted Partition wall with curved sides are kept at a distance from each other.
Die so erzielte Struktur bietet neben den die thermische Isolierung der gegenüberliegenden Wände betreffenden Vorteilen eine beträchtliche Starrheit oder strukturelle SteifigkeitThe structure achieved in this way offers thermal insulation as well as thermal insulation of the opposing walls, considerable rigidity or structural rigidity

Die Gesamtdicke, die Dicke der verschiedenen Elemente (Wände und Trennwand), die Winkelbildung der unterbrochenen Linie können schwanken als eine Funktion der insgesamt zu erreichenden Charakteristika.The total thickness, the thickness of the various elements (walls and partition), the angular formation of the broken line can vary as a function of the overall characteristics to be achieved.
Der Fertigungsgegenstand kann durch unterschiedslose Verwendung aller thermoplastschen Harze allein oder in Verbindung miteinander durch gemeinsames Strangpressen realisiert werden (beispielsweise die Wände aus einer bestimmten Materialart und -lie Trennwand aus einem anderen Material), um so von Fall zu Fall die beste Leistung bei günstigsten Gesamtkosten für den Fertigungsgegenstand zu erzielen. The article of manufacture can be achieved by indiscriminately using all thermoplastic resins alone or in combination with one another can be realized by joint extrusion (for example the walls are made of a certain type of material and the partition wall another material) in order to achieve the best performance on a case-by-case basis at the lowest overall cost for the object of manufacture.
