Description

Die Erfindung betrifft eine rechteckige Isolierplatte aus stauchungssteifem Schaumkunststoff, vorzugsweise Polystyrol, zur Wärmedämmung zwischen den Dachsparren geneigter Kaltdächer.The invention relates to a rectangular insulating plate made of compression-resistant foam plastic, preferably polystyrene, for thermal insulation between the rafters of inclined cold roofs.

Isolierplatten dieser Art sollen zwischen den Dachsparren möglichst lückenlos eingepaßt werden. Da die Dachsparren nicht immer genau auf einen vorbestimmten, genormten Abstand verlegt sind, muß man Isolierplatten dieser Art im Übermaß bereitstellen und durch Abtrennen des Übermaßes passend machen. Das ist sehr umständlich.Insulation plates of this type should be fitted as seamlessly as possible between the rafters. Since the rafters are not always placed exactly at a predetermined, standardized distance, insulating plates of this type must be provided in excess and made to fit by separating the excess. It is very cumbersome.

Ls sind auch Isolierplatten im Übermaß bekannt, die im mittleren Bereich eine Stauchungszone aufweisen, die gebildet ist durch einander überlappende, von beiden Seiten ausgehende Längsnuten. Diese Längsnuten beeinträchtigen die angestrebte Wärmedämmung umsomehr, je breiter und je tiefer sie sind; wenn man sie nur klein ausgestaltet, dann ist die damit erzielbare Stauchung so gering, daß sich die in der Praxis auftretenden Toleranzen nur in Ausnahmefällen überbrücken lassen.Ls are also known excessively insulating plates which have a compression zone in the central region, which is formed by overlapping longitudinal grooves extending from both sides. These longitudinal grooves affect the desired thermal insulation, the wider and the deeper they are; if they are made small, then the compression that can be achieved with them is so small that the tolerances that occur in practice can only be bridged in exceptional cases.

Aufgabe der Erfindung ist es, eine Isolierplatte der eingangs genannten Art so auszugestalten, daß sie in die Dachsparrenzwischenräume mit möglichst großer Toleranzbreite festsitzend einpaßbar ist, und zwar bei einfacher Handhabung und unter möglichst geringem Verlust an wärmedämmender Wirkung.The object of the invention is to provide an insulating board of the aforementioned A rt be so designed that it is tightly fittable in the rafter gaps with the greatest possible tolerance range, namely with simple handling and with the lowest possible loss of heat-insulating effect.

Die Erfindung ist dadurch gekennzeichnet, daß entlang zweier, einander gegenüberliegender Plattenränder je ein Randstreifen zur gleichen Plattenseite im spitzen Winkel zum Mittelteil der Platte geneigt ist und daß diese Randstreifen durch in dem genannten spitzen Winkel zum Mittelteil der Platte geneigte Längsnuten in Rippen aufgespalten sind. Die Plattenränder schmiegen sich beim Einklemmen auch zwischen verwundenen Balken gut an diese an.The invention is characterized in that along each of two plate edges lying opposite one another, one edge strip is inclined to the same side of the plate at an acute angle to the central part of the plate and that these edge strips are split into ribs by longitudinal grooves inclined at said acute angle to the central part of the plate. The plate edges are nestled in the pinching between twisted beams g ut on to them.

Vorteilhaft im Interesse einer thermischen Isolierung auch im Randbereich sind Randstreifen, die jeweils durch mehrere Längsnuten in Rippen aufgespalten sind. Aus fertigungstechnischen. Gründen ist es vorteilhaft, wenn die Längsnuten V-förmigen Querschnitt haben.In the interest of thermal insulation in the edge area, too, edge strips are advantageous, each of which is split into ribs by a plurality of longitudinal grooves. From manufacturing technology. For reasons, it is advantageous if the longitudinal grooves have a V-shaped cross section.

Die gewünschte Einpassung wird begünstigt, wenn die Rippen zu ihrem freien Ende hin zunehmend biegbarer sind, und das kann man sehr einfach erzielen, wenn sich die Rippen zu ihrem freien Ende hin, bezogen auf den Querschnitt, verjüngen. Durch den erwähnten V-förmigen Querschnitt der Längsnuten kann man eine solche Verjüngung leicht erzielen.The desired fit is favored if the ribs are increasingly bendable towards their free end, and this can be achieved very easily if the ribs taper towards their free end in relation to the cross section. Such a taper can easily be achieved by the aforementioned V-shaped cross section of the longitudinal grooves.

Die Längsnuten, die den Randstreifen aufspalten, erstrecken sich in der Tiefe des Randstreifens. Die für den angestrebten Zweck optimale Tiefe ist abhängig von der Stärke der Platte. Abmessungen mit einer Breite des Randstreifens von 60 mm bis 100 mm, vorzugsweise 80 mm, haben sich für die gängigen Plattenstärken in der gleichen Größenordnung liegend bewährt.The longitudinal grooves that split the edge strip extend in the depth of the edge strip. The optimum depth for the intended purpose depends on the thickness of the plate. Dimensions with a width of the edge strip of 60 mm to 1 00 mm, preferably 80 mm, have proven themselves to be in the same order of magnitude for the common plate thicknesses.

Setzt man eine Platte nach der Erfindung mit den Randbereichen zu den Dachsparren und gegen die Einschubrichtung weisend in den Zwischenraum zwischen die Dachsparren, dann werden die Rippen nach hinten gebogen, bis Passung erzielt ist, und wirken dann als Widerhaken. Durch diese Ausgestaltung der Randstreifen läßt sich eine verhältnismäßig breite Toleranz hinsichtlich des zwischen den Dachsparren zur Verfügung stehenden Zwischenraums überbrücken, weil sich in der Praxis die Breite der Platte durch Umbiegen der Rippen um etwa die Hälfte der Rippenhöhe verringern läßt.If you place a plate according to the invention with the edge areas towards the rafters and pointing against the direction of insertion into the space between the rafters, then the ribs are bent backwards until a fit is achieved and then act as barbs. This configuration of the edge strips allows a relatively wide tolerance to be bridged with regard to the space available between the rafters, because in practice the width of the plate can be reduced by about half the height of the ribs by bending the ribs.

Für eine im Sinne der genannten Aufgabenstellung angestrebte Optimierung empfehlen sich Abmessungen wie folgt. Der spitze dinkel, mit dem die Randstreifen geneigt sind, beträgt 30 bis 36°, vorzugsweise 33°. Es empfiehlt sich, bei mehreren Platten, die zusammen gelagert und/oder verlegt und verarbeitet werden, diese mit einem jeweils gleichgroßen spitzen Winkel auszustatten, damit die Platten lückenlos stapelbar sind.For an optimization aimed at in the sense of the mentioned task, dimensions are recommended as follows. The acute dinkel with which the edge strips are slanted is 30 to 3 6 °, preferably 33 °. It is advisable to equip several panels that are stored and / or laid and processed together with an equally large acute angle so that the panels can be stacked without gaps.

Der öffnungswinkel der Längsnuten beträgt 15 bis 25°, vorzugsweise 20°. Bei Plattenstärken zwischen 50 und 100 mm empfiehlt es sich, auf jeder Seite zwei Längsnuten vorzusehen, so daß drei Rippen entstehen. Bei einer Plattenstärke von etwa 150 mm empfehlen sich drei Längsnuten mit vier Rippen und bei 180 mm starken Platten vier Längsnuten mit fünf Rippen.The opening angle of the longitudinal grooves is 15 to 25 °, preferably 20 °. For panel thicknesses between 50 and 1 00 mm, it is advisable to provide two longitudinal grooves on each side so that three ribs are created. With a panel thickness of approximately 150 mm, three longitudinal grooves with four ribs are recommended, and with 180 mm thick panels, four longitudinal grooves with five ribs.

Man kann die Anpassungsfähigkeit der Platte hinsichtlich der Breite noch vergrößern, indem man in an sich bekannter Weise in der Längsmitte zwischen den Randstreifen eine Ausgleichszone vorsieht. 3ine solche Ausgleichszone kann in an sich bekannter Weise gebildet werden durch von beiden Plattenoberflächen ausgehende, einander in der Tiefe überlappende, senkrecht zur Plattenoberfläche sich erstreckende Stauchnuten.You can increase the adaptability of the plate in terms of width by providing a compensation zone in the conventional manner in the longitudinal center between the edge strips. Such a compensation zone can be formed in a manner known per se by compression grooves extending from both plate surfaces and overlapping one another in depth and extending perpendicular to the plate surface.

Man kann eine solche Ausgleichszone gemäß einer Weiterbildung der Erfindung auch dadurch erzielen, daß die Platten entlang einer Nut- und Federverbindung geteilt sind und die gegeneinandergleitenden Flächen der Nut- und Federverbindung eine Ver- zahnung beziehungsweise eine in diese Verzahnung passende Ge-genverzahnung aufweisen, durch die die Nut- und Federverbindung in verschiedenen Einstecktiefen festlegbar sind. M to such equalization zone can also be achieved that the plates along a N ut-and-groove connection are divided, and the mutually sliding surfaces of the tongue and groove connection a V ER- toothing or a suitable in this toothing G according to an embodiment of the invention e- have genverzahnung through which the tongue-and-F Eder compound at various insertion depths are fixed.

Die Zwischenräume zwischen den Dachsparren sind in der Regel um vieles länger als eine Platte und werden durch aneinandergesetzte Platten ausgefüllt. Dem trägt eine Weiterbildung der Erfindung Rechnung, die gekennzeichnet ist durch beim Aneinanderreihen gleichartiger Platten formschlüssig ineinanderpassende Profilierungen der beiden anderen Ränder.The gaps between the rafters are usually much longer than a plate and are filled by plates placed next to each other. This is taken into account by a further development of the invention, which is characterized by profiling of the two other edges that form fit into one another when rows of similar plates are lined up.

Die Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the accompanying drawing.

Die Isolierplatte 1 aus Figur 1 besteht aus stauchungssteifem Schaumkunststoff und ist rechteckig. Die Breite ist durch den Doppelpfeil 6, die Länge durch den Doppelpfeil 7 und die Stärke ist durch den Doppelpfeil 31 angezeigt. Entlang zweier gegenüberliegender Seiten sind Randstreifen 2 und 3 abgeteilt, die beide gleich breit sind. Ihre Breite ist durch den Doppelpfeil 5 1 angezeigt. Diese Randstreifen 2, 3 sind im spitzen Winkel gemäß Doppelpfeil 4, bezogen auf Figur 2 nach unten, abgewinkelt. Die Randstreifen 2, 3 sind mit je zwei sich über den ganzen Randstreifen erstreckenden, V-förmigen Querschnitt aufweisenden Längsnuten 9, 10, 11, 12 ausgestattet, so daß auf jeder Seite insgesamt drei Rippen entstehen, zum Beispiel die Rippen 13, 14, 15. Der Öffnungswinkel der Nuten 9, 10, 11 und 12 ist für alle Nuten der gleiche und durch den Doppelpfeil 32 angezeigt. Die Rippen verjüngen sich, bezogen auf ihren Querschnitt, zu ihrem freien Ende hin und werden zu ihrem freien Ende hin auch nachgiebiger.The insulating plate 1 from Figure 1 consists of compression rigid foam plastic and is rectangular. The width is indicated by the double arrow 6, the length by the double arrow 7 and the thickness is indicated by the double arrow 31. Edge strips 2 and 3 are divided along two opposite sides, both of which have the same width. Their width is indicated by the double arrow 5 1. These edge strips 2, 3 are angled at an acute angle according to the double arrow 4, based on FIG. 2. The edge strips 2, 3 are each equipped with two longitudinal grooves 9, 10, 11, 12, which extend over the entire edge strip and have a V-shaped cross section, so that a total of three ribs are formed on each side, for example the ribs 13, 14, 15 . The opening angle of the grooves 9, 10, 11 and 12 is the same for all grooves and is indicated by the double arrow 32. The ribs taper in relation to their cross-section towards their free end and also become more flexible towards their free end.

entlang der beiden anderen Seiten sind einfache Stufenprofilierungen 20, 21 vorgesehen, die bei aneinandergereihten, gleichartigen Platten formschlüssig ineinanderpassen.along the other two sides, simple step profiles 20, 21 are provided, which are the same when strung together like plates fit into each other.

Die Platte 1 kann, wie in Figur 6 dargestellt, in dem Zwischenraum 22 zwischen zwei wie üblich parallel verlegten Dachsparren 23, 24 eines geneigten Kaltdaches eingesetzt werden. Das geschieht, indem man die Isolierplatte 1 gemäß Pfeil 25 von unten einschiebt. Eine passende Isolierplatte muß dabei hinsichtlich ihrer Länge gemäß Doppelpfeil 7 etwas Übermaß haben gegenüber der Gesamtbreite gemäß Doppelpfeil 26 des Zwischenraums, damit sich die als Widerhaken wirkenden Rippen an beiden Dachsparren festsetzen und verhaken. Das Übermaß kann beträchtlich sein. In dieser Hinsicht ist die Erfindung geeignet, erhebliche Toleranzen aufzufangen, indem dann die Rippen 13, 14, 15 und die auf der anderen Seite gelegenen Rippen umgebogen werden, wie dies rechts in Figur 6 angedeutet ist, für den Fall, daß eine Dachsparre entlang der strichpunktierten Linie 27 endet. Für die in Figur 6 gezeichnete Isolierplatte 1 kann der Zwischenraum äußerstenfalls die Breite gemäß Doppelpfeil 26 haben; er muß aber mindestens die Breite gemäß Doppelpfeil 28 haben. Der Dop- pelpfeil 28 erstreckt sich von der strichpunktierten Linie 27 bis zu einer symmetrisch dazu gezeichneten, strichpunktierten Linie 29 auf der anderen Seite.In the intermediate space 22, the plate 1, as shown in Figure 6, between two parallel routed as usual D achsparren 23, 24 of an inclined roof cold be used. This is done by inserting the insulating plate 1 according to arrow 25 from below. A suitable insulating plate must have a slight oversize in terms of its length according to double arrow 7 compared to the total width according to double arrow 26 of the intermediate space, so that the ribs acting as barbs attach to and catch on both rafters. The excess can be considerable. In this regard, the invention is capable of accommodating considerable tolerances by then bending the ribs 1 3, 1 4, 1 5 and the ribs on the other side, as indicated on the right in FIG. 6, in the event that one Roof lock along the dash-dotted line 27 ends. For the insulating plate 1 shown in FIG. 6, the space can at most have the width according to double arrow 26; but it must have at least the width according to double arrow 28. The D optically pelpfeil 28 extends from the dash-dotted line 27 up to a drawn symmetrically thereto, dot-dash line 29 on the other side.

Bevorzugte Abmessungen der Isolierplatte nach Figur 1, 2, 3, 6 und 7 ergeben sich aus der nachfolgenden Tabelle unter Beispiel 1, 2, 3 und 8. Abänderungen entsprechend den übrigen Beispielen der Tabelle sind möglich.

Das in Figur 4 dargestellte, abgeänderte Ausführungsbeispiel unterscheidet sich von dem Ausführungsbeispiel nach Figur 1 bis 3 nur durch einen Stauchungsbereich 40, der sich in der Mitte zwischen den genuteten Randabschnitten 41, 42 erstreckt. Dieser Stauchungsbereich entsteht dadurch, daß beidseitig Längsnuten 43, 44, 45, 46 vorgesehen sind, die einander überlappen und senkrecht von den beiden Oberflächen 47, 48 ausgehen.The modified exemplary embodiment shown in FIG. 4 differs from the exemplary embodiment according to FIGS. 1 to 3 only by a compression region 40 which extends in the middle between the grooved edge sections 41, 42. This S tauchungsbereich arises in that both sides of the longitudinal grooves 43, 44, 45, 46 are provided, which overlap each other in and out perpendicularly from the two surfaces 47, 48th

Das Ausführungsbeispiel nach Figur 5 unterscheidet sich von dem Ausführungsbeispiel nach Figur 1 bis 3 nur durch eine Ausgleichszone 50 in der Längsmitte zwischen den abgewinkelten Randstreifen 51, 52. In der Ausgleichszone 50 ist die Isolierplatte 53 geteilt, so daß zwei Plattenteile 54, 55 entstehen, die mit Hilfe einer modifizierten Nut- und Federverbindung 56 zusammengesteckt sind. Die Nut- und Federverbindung 56 weist entlang ihrer Gleitflächen 57, 58 Längsverzahnungen auf, mit denen es möglich ist, die beiden Plattenteile 54, 55 mehr oder weniger Tief ineinandergesteckt zu arretieren. In der Zeichnung sind die beiden Plattenteile 54, 55 maximal zusammengeschoben, die Platte 53 ist also in der Ausgleichszone 50 maximal gestaucht. Zieht man die beiden Plattenteile 54, 55 auseinander, was durch Verschieben in Richtung senkrecht zur Zeichenebene der Figur 5 geschieht, und steckt sie neu zusammen mit geringerer Eindringtiefe der Nut- und Federverbindung 56, dann entsteht eine insgesamt breitere Platte.The exemplary embodiment according to FIG. 5 differs from the exemplary embodiment according to FIGS. 1 to 3 only by a compensating zone 50 in the longitudinal center between the angled edge strips 51, 52. In the compensating zone 50, the insulating plate 53 is divided, so that two plate parts 54, 55 are formed, which are plugged together using a modified tongue and groove connection 56. The tongue and groove connection 56 has longitudinal toothing along its sliding surfaces 57, 58, with which it is possible to lock the two plate parts 54, 55 more or less deeply into one another. In the drawing, the two plate parts 54, 55 are pushed together to the maximum, the plate 53 is thus maximally compressed in the compensation zone 50. If you pull the two plate parts 54, 55 apart, which is done by moving them in the direction perpendicular to the plane of the drawing in FIG. 5, and then insert them together with a lower depth of penetration of the tongue and groove connection 56, then an overall wider plate is produced.

Die Ausführungsbeispiele aus Figur 8 bis 15 unterscheiden sich von dem Ausführungsbeispiel nach Figur 1 nur durch die Ausge- staltung der Randstreifen wie dargestellt. Die in den Figuren nicht dargestellten Randstreifen auf der anderen Seite sind spiegelbildlich zu den dargestellten ausgebildet und dementsprechend nach der gleichen Seite, also bezogen auf die Figuren nach unten, geneigt.The embodiments of Figure 8 to 15 differ from the embodiment of Figure 1 only by the A usge- the edge strip staltung as illustrated. The edge strips, not shown in the figures, on the other side are mirror images of the ones shown and are accordingly inclined to the same side, that is to say downwards in relation to the figures.

In diesen Figuren sind dargestellt: Isolierplatten 60 bis 67, Randstreifen 70 bis 77, Längsnuten 80 bis 85 und Rippen 100 bis 123. Die Randstreifen 70 bis 74 erstrecken sich zwischen den strichpunktierten Linien 124, 125 und die Randstreifen 75 bis 77 erstrecken sich zwischen den strichpunktierten Linien 126, 127. Bei den Figuren 9 und 10 stehen die Außenflächen 128 bis 131 paarweise im spitzen Winkel 134 beziehungsweise 1.35 von etwa 4° aufeinander. Bei allen anderen Ausführungsbeispielen stehen die entsprechenden Außenflächen planparallel zueinander. Bei allen Ausführungsbeispielen sind die Randstreifen im spitzen Winkel gemäß Doppelpfeil 140 bis 147 gegenüber dem Mittelteil der betreffenden Isolierplatte 60 bis 67 geneigt.In these figures are shown: insulating plates 60 to 67, edge strips 70 to 77, longitudinal grooves 80 and 85 and ribs 1 00-1 23. The edge strips 70 to 74 extend between the dotted lines 124, 125 and the edge strips 75 to 77 extend between the dash-dotted lines 126, 127. In FIGS. 9 and 10, the outer surfaces 128 to 131 are in pairs at an acute angle 134 and 1.35 of approximately 4 ° to one another. In all other exemplary embodiments, the corresponding outer surfaces are plane-parallel to one another. In all of the exemplary embodiments, the edge strips are inclined at an acute angle according to double arrow 1 40 to 1 47 relative to the central part of the insulating plate 60 to 67 in question.

Die Längsnuten 80 bis 84 und die Rippen 100 bis 114 haben V-förmigen Querschnitt. Gemäß einer Abänderung der Ausführungsbeispiele nach Figur 8 bis 12 erstrecken sich die Randstreifen nur von der strichpunktierten Linie 124 bis zur strichpunktierten Linie 150, sind also gegenüber den Darstellungen entlang der strichpunktierten Linie 150 abgeschnitten zu denken. Die Folge ist, daß der Querschnitt der Längsrippen dann trapezförmig ist. Die Nuten 90 und 91 sowie 94 und 95 sind Einschnitte mit rechteckigem Querschnitt. Die Längsnuten 92, 93 sind Einschnitte mit U-förmigem Querschnitt. Die Rippen 115 bis 123 sind auf ihrer ganzen Länge gleich stärk, die Rippen 115 bis 120 enden entlang der strichpunktierten Linie127, während die Rippen 121 bis 123 entlang der Linie 127 Abrundungen aufweisen.The longitudinal grooves 80 to 84 and the ribs 1 00 to 1 1 4 have a V-shaped cross section. According to a modification of the exemplary embodiments according to FIGS. 8 to 12, the edge strips only extend from the dash-dotted line 124 to the dash-dotted line 150, and are therefore to be thought of as being cut off from the representations along the dash-dotted line 150. The result is that the cross section of the longitudinal ribs is then trapezoidal. The grooves 90 and 91 and 94 and 95 are cuts with a rectangular cross section. The longitudinal grooves 92, 93 are incisions with a U-shaped cross section. The ribs 115 to 123 are of equal thickness over their entire length, the ribs 115 to 120 end along the dash-dotted line 127, while the ribs 1 21 to 1 23 have roundings along the line 127.

Für jeden Randbereich sind nach Figur 8 und 9 jeweils eine Längsnut mit je zwei Rippen, nach Figur 10, 13, 14 und 15 zwei Längsnuten mit jeweils drei Rippen und nach Figur 11 und 12 drei Längsnuten mit jeweils vier Rippen vorgesehen.According to FIGS. 8 and 9, a longitudinal groove with two ribs each is provided for each edge region, two longitudinal grooves with three ribs each according to FIGS. 10, 13, 14 and 15, and three longitudinal grooves with four ribs each according to FIGS. 11 and 12.

Abänderungen durch Kombination der aus den Figuren 8 bis 15 ersichtlichen Merkmale sind möglich. Bevorzugte Abmessungen ergeben sich in Anlehnung an die Tabelle.Modifications by combining the features shown in FIGS. 8 to 15 are possible. Preferred dimensions are based on the table.
