Description

Die Erfindung betrifft eine Dämmplatte aus thermisch und ggf. akustisch isolierenden Dämmstoffen mit einem sich verjüngenden Ende und mit einem sich nach außen insb. längs Schrägflächen öffnenden anderen Ende zum Zusammenstecken von benachbarten Dämmplatten.The invention relates to an insulation board made of thermally and possibly acoustically insulating insulation materials with a tapering end and with another end opening outward, in particular along oblique surfaces, for plugging together adjacent insulation boards.

Derartige Dämmplatten aus beispielsweise Kork, Mineralwolle und aufgeschäumtem Kunststoff sind bereits bekannt. Außer den Nut-Feder-Verbindungen zwischen benachbarten, Stoß an Stoß anliegenden Dämmplatten wie nach der SU-PS 29 39 81 ist es auch bekannt, ein Dämmplattenende so zuzuspitzen, daß der äußere Rand an einer Spitze zuläuft, von der sich je eine Schrägfläche zu den beiden Außenflächen der Dämmplatte hinzieht. Das andere Ende der Dämmplatte ist mit einer schwalbenschwanzartigen Aussparung versehen, die zur Aufnahme des angespitzten entgegengesetzten Endes einer benachbarten Dämmplatte dient. Auf diese Weise ist es möglich, eine Reihe von Dämmplatten aneinander anzusetzen und über deren angespitzte bzw. schwalbenschwanzförmig ausgesparten Enden miteinander zu verfugen.Such insulation boards made of, for example, cork, mineral wool and foamed plastic are already known. In addition to the tongue and groove connections between adjacent, butt-to-butt insulation boards as in SU-PS 29 39 81, it is also known to taper an insulation board end so that the outer edge tapers at a tip, from each of which an inclined surface the two outer surfaces of the insulation board. The other end of the insulation board is provided with a dovetail-like recess, which serves to receive the pointed opposite end of an adjacent insulation board. In this way it is possible to attach a row of insulation boards to one another and to joint them over their pointed or dovetail-shaped ends.

Während bei solchen Schwalbenschwanz-Verbindungen bei der Montage jeweils dafür Sorge zu tragen ist, daß die gerade verlegte Dämmplatte nicht selbständig aus der gewünschten Endlage herausrutscht, bei der die Schrägflächen der Spitze an den Schrägflächen der schwalbenschwanzförmigen Aussparung anliegen, ist das Verbinden benachbarter Dämmplatten durch Einsetzen einer Feder eine gewisse Erschwernis, welche die Verlegearbeit verteuert.While with such dovetail connections, care must be taken during assembly to ensure that the insulation board just laid does not automatically slip out of the desired end position, in which the inclined surfaces of the tip lie against the inclined surfaces of the dovetail-shaped recess, the connection of adjacent insulation boards is achieved by inserting them a feather a certain difficulty, which makes the laying work more expensive.

Darüber hinaus ist es bekannt (DE-GM 87 03 088), die schrägverlaufenden, bei Verlegen aneinanderstoßenden Enden von Dämmplatten stufenartig auszubilden, um ein ungewolltes Verschieben aneinanderliegender Dämmplatten beim Verlegen zu vermeiden.In addition, it is known (DE-GM 87 03 088) to design the sloping ends of insulation boards that abut when laying, in order to avoid undesired displacement of adjacent insulation boards when laying.

Der Erfindung liegt die Aufgabe zugrunde, eine Dämmplatte der eingangs genannten Gattung mit einfachen Mitteln dahingehend zu verbessern, daß die Montage bzw. Demontage einfach auch durch Laien durchführbar ist, ohne daß besondere Vorrichtungen verwendet werden müssen, die ein ungewolltes Herausrutschen der gerade montierten Dämmplatte aus der Position verhindert, welche der endgültigen Montagestellung entspricht.The invention has for its object to improve an insulation board of the type mentioned with simple means to the effect that the assembly or disassembly can be carried out easily even by laymen, without the need to use special devices that prevent unwanted slipping out of the just installed insulation board the position which corresponds to the final assembly position.

Die Erfindung ist im Anspruch 1 gekennzeichnet und in Unteransprüchen sind weitere Ausbildungen derselben beschrieben. Anhand der Zeichnung wird auch in der folgenden Figurenbeschreibung ein besonders bevorzugtes Anwendungsbeispiel geschildert.The invention is characterized in claim 1 and further embodiments of the same are described in subclaims. Based on the drawing, a particularly preferred example of use is also described in the following description of the figures.

Bei der Erfindung ist das sich nach außen öffnende Ende der Dämmplatte innen mit einer Aussparung versehen oder -mit anderen Worten- das sich zum Rand der Dämmplatte öffnende Ende ist innen, d.h. an der den betreffenden Rand entgegengesetzten Seite, aufgeweitet. An der Übergangsstelle zwischen der beginnenden Aufweitung und den zum betreffenden Rand sich insbesondere keilförmig hinziehenden Schrägflächen befindet sich mindestens eine Sperrnase zur Bildung einer Engstelle in diesem Übergangsbereich zur entsprechenden Schrägfläche.In the invention, the outwardly opening end of the insulation board is provided with a recess on the inside or - in other words - the end that opens to the edge of the insulation board is on the inside, i.e. on the opposite side of the edge in question. At the transition point between the beginning of the widening and the inclined surfaces, which in particular wedge-shaped extend toward the edge in question, there is at least one locking lug to form a narrow point in this transition region to the corresponding inclined surface.

Am anderen, sich verjüngenden Ende ist die Dämmplatte dagegen mit einem Sperrteil oder -mit anderen Worten- mit einem sich aufweitenden Teil versehen, dessen größte Breite grösser ist als die Breite einer Engstelle im Bereich des Übergangs dieses Sperrteils bzw. dieser Aufweitung in die betreffende Schrägfläche, welche zur betreffenden Außenfläche der Dämmplatte führt. Die größte Breite des Sperrteils ist auch größer als die Breite der vorher genannten Engstelle im Bereich der Sperrnase des zuerst genannten Endes der Dämmplatte.At the other, tapering end, the insulation board, on the other hand, is provided with a blocking part or - in other words - with a widening part, the greatest width of which is greater than the width of a constriction in the area of the transition of this blocking part or this widening into the sloping surface in question , which leads to the relevant outer surface of the insulation board. The greatest width the locking part is also greater than the width of the aforementioned narrow point in the area of the locking lug of the first mentioned end of the insulation board.

Außerdem beteht die Dämmplatte entweder im Bereich der Sperrnase oder im Bereich des Sperrteils bzw. der Ausweitung oder bevorzugt in beiden Bereichen aus einem Material, daß sich bei Druck insb. zu einem gewissen Teil kompressibel verformt, um nach dem Nachlassen des Druckes weitgehend wieder seine Ursprungsform einzunehmen.In addition, the insulation board is either in the area of the locking lug or in the area of the locking part or the extension or preferably in both areas made of a material that deforms compressively to a large extent when pressure is released, in order to largely return to its original shape after the pressure has released to take.

Auf diese Weise gelingt es, daß bei Angreifen des Sperrteils des einen Dämmplattenendes an der oder den Sperrnasen des anderen Endes einer benachbarten Dämmplatte und bei Anwendung eines die beiden Dämmplatten in ihrer "ineinandergefugte" Montagestellung drängenden Druckes der Sperrteil an der Sperrnase vorbei in die Aussparung gedrückt wird, während die Sperrnasen in der "ineinandergefugten" Montagestellung in den Übergangsbereich zwischen dem Sperrteil und den Schrägflächen des einen Dämmplattenendes hineingreifen und den Sperrteil daran hindern, wieder selbsttätig, d.h. ohne ausgesprochenen Zug an der betreffenden Dämmplatte, aus der Ausparung herauszugelangen.In this way it is possible that when attacking the locking part of one end of the insulation board at the one or more locking lugs of the other end of an adjacent insulation board and when using a pressure urging the two insulation boards in their "nested" assembly position, the locking part is pressed past the locking lug into the recess is, while the locking lugs reach into the "nested" assembly position in the transition area between the locking part and the inclined surfaces of one end of the insulation board and prevent the locking part from again automatically, ie to get out of the recess without pronounced pull on the insulation board in question.

Nach einer besonderen Ausbildung befindet sich der Rand der Aussparung auf einem Kreis mit einem Durchmesser, welcher mindestens der größten Breite des Sperrteils entspricht. Entsprechend sollte auch der Rand des Sperrteils sich auf einem Kreis mit einem solchen Durchmesser befinden, welcher der größten Breite des Sperrteils entspricht. Sowohl die Aussparung als auch der Sperrteil bilden dann im Querschnitt eine Art Halbmond oder Dreiviertelmond. Die Engstelle befindet sich dabei zweckmäßigerweise an der Übergangsstelle zwischen dem Rand der Aussparung bzw. des Sperrteils und der angrenzenden Schrägfläche.According to a special design, the edge of the recess is on a circle with a diameter which corresponds to at least the greatest width of the locking part. Accordingly, the edge of the locking part should also be on a circle with a diameter that corresponds to the greatest width of the locking part. Both the recess and the blocking part then form a kind of crescent moon or three-quarter moon in cross section. The constriction is expediently located at the transition point between the edge of the recess or the blocking part and the adjacent inclined surface.

Die Breite der Engstelle des Sperrteils sollte zwischen 50% und 95% der größten Breite desselben betragen, während die Breite der Engstelle an der Sperrnase zwischen 85% und 98% der größten Breite des Sperrteils betragen sollte.The width of the constriction of the locking part should be between 50% and 95% of the greatest width of the same, while the width of the constriction at the locking lug should be between 85% and 98% of the greatest width of the locking part.

Das Verhältnis der größten Breite des Sperrteils in Bezug zur Dicke der Basisplatte sollte zwischen 30% und 80% betragen.The ratio of the largest width of the locking part in relation to the thickness of the base plate should be between 30% and 80%.

Der Sperrteil und die Aussparung sollten sich jeweils über die gesamte Breite der Dämmplatte hinziehen, doch sind auch abgewandelte Ausbildungen möglich, bei denen beispielsweise der Sperrteil nicht über die gesamte Breite der Dämmplatte verläuft, sondern nur einem Teil der Breite entspricht, beispielsweise sich nur in der Mitte oder an den Rändern befindet.The locking part and the recess should each extend over the entire width of the insulation board, but modified designs are also possible in which, for example, the locking part does not run over the entire width of the insulation board, but only corresponds to part of the width, for example only in the Located in the middle or on the edges.

Als Dämmstoff empfehlen sich insb. folgende:
Holzfaserplatten und Dämmstoffe aus Holzwerkstoffen, Faserdämmstoffe in Form von Platten,- oder Rollenware, Schaumdämmstoffe in Form von Hart,- und Weichschäume sowie Korkerzeugnisse.The following are particularly recommended as insulation:
Wood fiber boards and insulation materials made of wood materials, fiber insulation materials in the form of sheets or rolls, foam insulation materials in the form of hard and soft foams as well as cork products.

Gemäß Figur 1 weist das sich nach unten öffnende untere Ende 10 der oberen Dämmplatte 1 zentral in der Mitte eine etwa halb- bis dreiviertel-mondförmige Aussparung 2 auf, die im Bereich zweier Sperrnasen 8 in Schrägflächen 6 übergeht, welche die Aussparung 2 im Zentrum der Dämmplatte 1 mit den beiden Außenseiten 1a bzw. 1b verbinden. Diese in Fig. 1 oben dargestellte Dämmplatte 1 und auch die dort unten dargestellte benachbarte Dämmplatte 1 weisen als Dämmstoff Hartschaum auf.According to FIG. 1, the downwardly opening lower end 10 of the upper insulation board 1 has an approximately half to three-quarter moon-shaped recess 2 in the center, which is in the region of two Locking lugs 8 merges into inclined surfaces 6, which connect the recess 2 in the center of the insulation board 1 with the two outer sides 1a and 1b. This insulation plate 1 shown at the top in FIG. 1 and also the adjacent insulation plate 1 shown there below have rigid foam as the insulation material.

Am oberen sich verjüngenden Ende 11 ist die untere Dämmplatte 1 mit einem Sperrteil 4 versehen, welcher im Querschnitt wiederum halb- bis dreiviertel-mondförmig ausgebildet ist. Der äußere Rand des Sperrteils 4 erstreckt sich auf einem Kreis bis zu einer Einschnürung 7, um von da aus längs der Schrägflächen 5 bis zu den beiden Außenflächen 1a, 1b überzugehen.At the upper tapering end 11, the lower insulation board 1 is provided with a locking part 4, which in turn is half-to-three-quarter moon-shaped in cross section. The outer edge of the locking part 4 extends in a circle up to a constriction 7 in order to pass from there along the inclined surfaces 5 to the two outer surfaces 1a, 1b.

In dieser montierten Sperrstellung verhindern die beiden Sperrnasen 8 an beiden Enden der Aussparung 2, daß der Sperrteil 4 aus der in Fig. 1 gezeigten Montage- bzw. Sperrstellung nach unten herausrutscht. Es ist daher möglich, beim Montieren sowohl Dämmplatten jeweils von oben auf benachbarte untere Dämmplatten aufzusetzen als auch jeweils Dämmplatten von unten an sich darüber befindliche Dämmplatten anzusetzen und dort in der Sperrstellung "aufzuhängen".In this assembled locking position, the two locking lugs 8 on both ends of the recess 2 prevent the locking part 4 from slipping out of the mounting or locking position shown in FIG. 1. It is therefore possible to mount insulation boards from above onto adjacent lower insulation boards as well as to install insulation boards from below on insulation boards located above them and "hang up" there in the locked position.

Damit möglichst keine Fremdkörper und Feuchtigkeit, wie Schlagregen, in den Zwischenraum zwischen den beiden Enden 10,11 hineingelangen und dort verbleiben, empfiehlt sich die in Fig. 1 gezeigte Montagestellung, bei der die sich verjüngenden Enden jeweils oben und die sich nach außen öffnenden Enden mit der Aussparung 2 jeweils nach unten angeordnet sind. Läuft Regenwasser in Pfeilrichtung an den Außenflächen 1a der aus den Dämmplatten 1 gebildeten vorgehängten Wand nach unten, kann kein Wasser in der Fuge zwischen den benachbarten montierten Dämmplatten 1 nach oben steigen, so daß ein zusätzliches Isolieren durch beispielsweise Einspritzen von Fugendichtungsmasse überflüssig wird.So that as far as possible no foreign bodies and moisture, such as driving rain, get into the space between the two ends 10, 11 and remain there, the mounting position shown in FIG. 1 is recommended, in which the tapering ends are at the top and the ends that open outward are arranged with the recess 2 downwards. If rainwater runs downward in the direction of the arrow on the outer surfaces 1a of the curtain wall formed from the insulation boards 1, no water can rise in the joint between the adjacent installed insulation boards 1, so that additional insulation by, for example, injection of jointing compound is unnecessary.

Gemäß Figur 2 ist der Rand 2a der Aussparung 2 abgerundet; er befindet sich auf einem Kreis mit dem Durchmesser A, welcher gleichzeitig die größte Breite der Aussparung 2 bildet. Der Rand 2a verläuft auf dem Kreis bis zu den beiden Sperrnasen 8. DerAccording to Figure 2, the edge 2a of the recess 2 is rounded; it is located on a circle with the diameter A, which at the same time forms the largest width of the recess 2. The edge 2a runs on the circle up to the two locking lugs 8. The

Abstand B der Sperrnasen 8 bildet die Engstelle 8a, an welcher der entsprechend mit seinem Außenrand 9 abgerundete Sperrteil 4 an der benachbarten unteren Dämmplatte 1 in der in Fig. 2 gezeigten Stellung anschlägt. Wird nun Druck auf die obere Dämmplatte 1 nach unten und/oder Druck auf die untere Dämmplatte 1 nach oben ausgeübt, dann vergrößert sich der Abstand B der Sperrnasen 8 durch Auseinanderdrücken derselben und/oder verkleinert sich die größte Breite D des Sperrteils 4 durch Kompression desselben, so daß der Sperrteil 4 an den Sperrnasen 8 vorbei in die Aussparung hineingelangen kann, wie dies in Fig. 1 in der montierten Sperrstellung gezeigt ist. Die Sperrnasen 8 schnappen dann in die dreieckförmigen Bereiche an den Übergangsstellen 7 zwischen dem äußeren Rand 9 des Sperteils 4 und den betreffenden Schrägflächen 5 des gleichen Endes der Dämmplatte 1 ein. Der Abstand C zwischen den Einschnürungen 7 bildet die Engstelle 7a.Distance B of the locking lugs 8 forms the constriction 8a, at which the locking part 4, correspondingly rounded with its outer edge 9, strikes the adjacent lower insulation board 1 in the position shown in FIG. 2. If pressure is now exerted on the upper insulation board 1 downwards and / or pressure is exerted on the lower insulation board 1 upwards, then the distance B of the locking lugs 8 increases by pushing them apart and / or the greatest width D of the locking part 4 is reduced by compression thereof , so that the locking part 4 past the locking lugs 8 can get into the recess, as shown in Fig. 1 in the assembled locking position. The locking lugs 8 then snap into the triangular areas at the transition points 7 between the outer edge 9 of the locking part 4 and the respective inclined surfaces 5 of the same end of the insulation board 1. The distance C between the constrictions 7 forms the constriction 7a.

Bei den in den Figuren 1 und 2 dargestellten Beispielen betragen die Winkel α der Schrägflächen 5,6 in Bezug zu den Außenflächen 1a, 1b der Dämmplatten 1 zwischen etwa 10 und 45° so, daß die Schrägflächen 5,6 etwa parallel verlaufen und aneinander anstoßen, wenn die montierte Sperrstellung nach Fig. 1 erreicht ist. Nach ein besonderen Ausbildung der Erfindung empfiehlt es sich jedoch, den Winkel α₁₀ der Schrägflächen 6 des unteren Endes 10 der oberen Dämmplatte 1, welche die Aussparung 2 aufweist, etwas größer zu wählen als den Winkel α₁₁ des oberen sich verjüngenden Endes 11 der unteren Dämmplatte 1. Rastet der Sperrteil 4 dann nämlich in die Aussparung 2 ein, bildet deren Rand 2a eine Art Lager, in dem sich der Sperrteil 4 etwas zu verdrehen vermag, so daß die untere Dämmplatte 1 auch in einem Winkel β in Bezug zur Ausrichtung der benachbarten Dämmplatte 1 verlegt werden kann. Hierdurch können gewölbte Wände erstellt bzw. gewölbte Gebäudeteile verkleidet werden, selbst wenn ungewölbte ebene und verhältnismäßig formsteife Dämmplatten 1 Verwendung finden. DieseIn the examples shown in FIGS. 1 and 2, the angles α of the inclined surfaces 5, 6 in relation to the outer surfaces 1 a, 1 b of the insulation boards 1 are between approximately 10 and 45 ° in such a way that the inclined surfaces 5, 6 run approximately parallel and abut one another when the assembled locking position according to FIG. 1 is reached. According to a special embodiment of the invention, it is recommended to choose the angle α₁₀ of the inclined surfaces 6 of the lower end 10 of the upper insulation board 1, which has the recess 2, somewhat larger than the angle α₁₁ of the upper tapered end 11 of the lower insulation board 1st If the locking part 4 then latches into the recess 2, the edge 2a forms a type of bearing in which the locking part 4 can twist somewhat, so that the lower insulation board 1 also forms an angle β with respect to the Alignment of the adjacent insulation board 1 can be laid. In this way, curved walls can be created or curved parts of the building can be clad, even if non-curved, flat and relatively dimensionally stable insulation boards 1 are used. This

Möglichkeit erlaubt die Anwendung der eingangs genannten bekannten Verfugungen mit Schwalbenschwanzenden einerseits und die ebenfalls eingangs genannten Feder-Nut-Verbindungen nicht ohne weiteres.Possibility does not allow the use of the known joints with dovetail ends mentioned at the beginning and the tongue and groove connections also mentioned at the beginning without further ado.

Es versteht sich, daß die Art der Ausbildung des Querschnitts der Aussparung, des Sperrteils und der Schrägflächen auch anders als bei der bevorzugten Ausbildung der Erfindung realisierbar ist und die Aufgabe der Erfindung unter Berücksichtigung des im Hauptanspruch genannten Prinzips realisiert werden kann, wonach es genügt, wenn sich an einem Ende der Dämmplatte ein Sperrteil befindet, der in eine Aussparung am anderen Ende der benachbarten Dämmplatte so einsetzbar ist, daß er beim Einsetzen einen bestimmten Widertand überwinden muß, der andererseits dafür sorgt, daß die betreffende Dämmplatte aus ihrer Montagestellung nicht selbständig ohne weiteres wieder herausrutscht, in der die Aussparung mit der Sperrnase bzw. den in den Figuren dargestellten beiden Sperrnasen eine Rast für den Sperrteil bildet, selbst wenn noch eine gewisse Bewegbarkeit insb. Schwenkbarkeit der beiden Dämmplatten in Bezug zueinander möglich ist.It goes without saying that the type of configuration of the cross section of the cutout, the locking part and the inclined surfaces can also be realized differently than in the preferred configuration of the invention and the object of the invention can be achieved taking into account the principle mentioned in the main claim, according to which it is sufficient if there is a locking part at one end of the insulation board, which can be inserted into a recess at the other end of the adjacent insulation board in such a way that it has to overcome a certain resistance when it is inserted, which on the other hand ensures that the insulation board in question is not without its own position slips out again, in which the recess with the locking lug or the two locking lugs shown in the figures forms a catch for the locking part, even if a certain degree of mobility, in particular pivoting of the two insulation boards in relation to one another, is still possible.

Fig. 3 ist ein Beispiel für eine solche Ausbildung der Erfindung, bei der die Dämmplattenenden 10, 11 nur jeweils an einer Seite 1a mit Schrägflächen 5, 6 versehen sind, die von einem Absatz 12, 13 zu entweder der Sperrnase 8 vor der Aussparung 2 oder der Engstelle 7a vor dem Sperrteil 4 führen. Der Sperrteil 4 weist bei dieser Ausbildung nur an der der einen Außenseite 1a der Dämmplatte 1 zugewandten Seite einen über die Engstelle 7a bzw. die Sperrnase 8 ausladenden Rand 9 auf, der beim Montieren an dieser unter Kompression vorbeigeschoben bzw. -gedrückt werden muß. An den entgegengesetzten Seiten weisen die Enden 10, 11 parallele Schiebeflächen 14, 14 auf, die auch parallel zu den Außenseiten 1, 1b der Dämmplatten 1 verlaufen.Fig. 3 is an example of such an embodiment of the invention, in which the insulation board ends 10, 11 are only provided on one side 1a with inclined surfaces 5, 6, which from a shoulder 12, 13 to either the locking lug 8 in front of the recess 2nd or the constriction 7a in front of the locking part 4. In this embodiment, the locking part 4 has an edge 9, which projects out over the constriction 7a or the locking lug 8, only on the one side facing the outer side 1a of the insulation panel 1, which edge 9, when it is mounted on it must be pushed or pushed under compression. On the opposite sides, the ends 10, 11 have parallel sliding surfaces 14, 14 which also run parallel to the outer sides 1, 1b of the insulation panels 1.
