Description

Die Erfindung betrifft eine Warmedämmplatte der im Oberbegriff des Anspruches 1 genannten Gattung.The invention relates to a thermal insulation board the one in the preamble of the claim 1 genus mentioned.

Warmedammplatten aus beispielsweise Glaswolle, Mineralwolle, aufgeschäumtem Kunststoff oder Kork sind bereits bekannt. Außer den Nut-Feder-Verbindungen zwischen benachbarten, Stoß an Stoß anliegenden Dämmplatten wie nach der DE-U-8 911 947 und 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 ausgesparte Enden miteinander zu verfugen. Thermal insulation boards made of glass wool, mineral wool, foamed plastic or cork are already known. In addition to the tongue and groove connections between neighboring Butt-to-butt insulation boards as in DE-U-8 911 947 and SU-PS 29 39 81 it is also known a Tip of the insulation board so that the outer edge at one Peak runs, from which there is an inclined surface to the two Pulls the outer surfaces of the insulation board. The other end of the Insulation board is with a dovetail-like recess provided to accommodate the sharpened opposite Endes an adjacent insulation board. That way it is possible to put a number of insulation boards together and recessed over their pointed or dovetail shape Joint the ends together.

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, bereiten kammartige Zungen mit verdickten Enden und hinter diesen einrastende Sperrblöcke gemäß DE-A-3 933 108 Montage- und vor allem Demontageprobleme. Das Verbinden benachbarter Dämmplatten durch Einsetzen einer Feder ist gleichfalls eine gewisse Erschwernis, welche die Verlegearbeit verteuert. While with such dovetail connections during assembly It must be ensured that the one just installed Insulation board not independently from the desired end position slips out, with the bevels of the tip on the Sloping faces of the dovetail-shaped recess, prepare comb-like tongues with thickened ends and behind them locking blocks according to DE-A-3 933 108 Assembly and especially disassembly problems. The connecting neighboring insulation boards by inserting a spring likewise a certain difficulty, which the laying work more expensive.

Darüber hinaus ist es bekannt (DE-U-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-U-87 03 088), the inclined, when laying abutting ends of insulation boards to train in a step-like manner in order to prevent accidental shifting of one another Avoid 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 an insulation board genus mentioned at the beginning with simple means improve that the assembly or disassembly simply by Layman is feasible without using special devices have to be, which is an unwanted slipping out of the just installed insulation board prevented from 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 in subclaims further training of the same are described. Based The drawing is also used in the following description of the figures described a particularly preferred application example.

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 outward opening end of the insulation board provided with a recess on the inside or with others Words - the end opening to the edge of the insulation board is inside, i.e. on the opposite side of the edge in question. At the transition point between the beginning of expansion and the edge in particular is wedge-shaped pulling inclined surfaces is at least one Blocking nose to form a constriction in this transition area 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 is on the other hand a blocking part or, in other words, an expanding part Provide part whose largest width is larger than that Width of a narrow point in the area of the transition of this blocking part or this expansion into the sloping surface in question, which for leads to the relevant outer surface of the insulation board. The greatest width the locking part is also larger than the width of the aforementioned Narrowing in the area of the locking nose of the first 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 blocking part or the extension or preferred in both areas made of a material that especially when printing. deformed to a certain extent in a compressible manner in order to Relief of the pressure largely returned to its original form 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 the one end of the insulation board on the other one or the locking lugs End of an adjacent insulation board and when using a die two insulation boards in their "nested" assembly position urging pressure of the locking part past the locking lug into the Recess is pressed while the locking tabs in the "nested" Installation position in the transition area between the locking part and the inclined surfaces of one end of the insulation board reach in and prevent the locking part from moving again automatically i.e. without pronounced pull on the concerned Insulation board to get out of the recess.

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. After a special training, the edge of the recess is located on a circle with a diameter of at least corresponds to the greatest width of the blocking part. Accordingly, it should also the edge of the locking part is on a circle with such a Diameter, which is the largest width of the locking part corresponds. Both the recess and the locking part then form a kind of crescent moon or three-quarter moon in cross-section. The constriction is conveniently located on the Transition point between the edge of the recess or the locking part and the adjacent sloping 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 blocking part should be between 50% and 95% of the largest width of the same, while the width of the Constriction at the locking nose between 85% and 98% of the greatest width of the blocking part should be.

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 Base plate thickness 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 cover the entire Pull the width of the insulation board, but they are also modified Training possible in which, for example, the locking part is not runs over the entire width of the insulation board, but only one Part of the width corresponds, for example, only in the middle or located on the edges.

Als Dämmstoff ist vorgesehen:
Faserdämmstoffe in Form von Platten- oder Rollenware, oder Korkerzeugnisse.The following is provided as insulation:
Fiber insulation materials in the form of sheets or rolls, or cork products.

A preferred embodiment of the invention is shown schematically in the drawing, which in
Fig. 1

Fig. 2
show an enlarged cross section in the same transition area of adjacent insulation boards before the assembled locking position is established and

a schematic partial section like FIG. 1 but from another embodiment of the invention.

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 la bzw. 1b verbinden.According to FIG. 1, the lower end 10 that opens downward has the upper insulation board 1 centrally in the middle of an approximately half to three-quarter moon-shaped recess 2 in the area of two Locking lugs 8 merges into inclined surfaces 6, which the recess 2 in the center of the insulation board 1 with the two outer sides la or Connect 1b.

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 la, 1b überzugehen.At the upper tapering end 11 is the lower insulation board 1 provided with a locking part 4, which in turn in cross section is formed half to three-quarter moon-shaped. The outer edge the locking part 4 extends in a circle to one Constriction 7 to from there along the inclined surfaces 5 to to merge two outer surfaces la, 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 prevent 8 at both ends of the recess 2 that the locking part 4th from the assembly or locking position shown in Fig. 1 down slips out. It is therefore possible to assemble both Insulation boards from above onto neighboring lower insulation boards to put on as well as insulation boards from below to place the existing insulation boards and there in the locked position "hang up".

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 la 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 stay there, the one shown in Fig. 1 is recommended Mounting position with the tapered ends at the top and the outwardly opening ends with the recess 2 are each arranged downwards. Runs rainwater in the direction of the arrow on the outer surfaces la of the insulation panels 1 formed curtain wall down, no water in the joint between the adjacent assembled insulation boards 1 upwards rise, so that additional insulation by, for example Injecting joint sealant becomes 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. Der 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 Sperrteils 4 und den betreffenden Schrägflächen 5 des gleichen Endes der Dämmplatte 1 ein. Der Abstand C zwischen den Einschnürungen 7 bildet die Engstelle 7a.According to Figure 2, the edge 2a of the recess 2 is rounded; he is on a circle with the diameter A, which at the same time forms the greatest width of the recess 2. The edge 2a runs on the circle up to the two locking lugs 8. The Distance B of the locking lugs 8 forms the constriction 8a at which the accordingly with its outer edge 9 rounded locking part 4 on the adjacent lower insulation board 1 in that shown in Fig. 2 Position strikes. Now pressure on the upper insulation board 1 after exerted at the bottom and / or pressure on the lower insulation board 1, then the distance B of the locking lugs 8 increases Pushing them apart and / or making the largest smaller Width D of the locking part 4 by compression of the same, so that the locking part 4 past the locking lugs 8 into the recess can get in, as shown in Fig. 1 in the assembled locking position is shown. 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 form 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 einer 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. Diese Möglichkeit erlaubt die Anwendung der eingangs genannten bekannten Verfugungen mit Schwalbenschwanzenden einerseits und die ebenfalls eingangs genannten Feder-Nut-Verbindungen nicht ohne weiteres.In the examples shown in FIGS. 1 and 2, the angles α of the inclined surfaces 5, 6 with respect to the outer surfaces 1 a, 1 b of the insulation boards 1 are between approximately 10 and 45 °, so 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, however, it is advisable to choose the angle α 10 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 α 11 of the upper tapering end 11 of the lower Insulating board 1. If the locking part 4 then clicks into the recess 2, its edge 2a forms a type of bearing in which the locking part 4 can twist somewhat, so that the lower insulating board 1 is also at an angle β with respect to the orientation of the neighboring insulation board 1 can be installed. 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 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.

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 is understood that the type of cross-section formation the recess, the locking part and the inclined surfaces also different than can be realized in the preferred embodiment of the invention and the object of the invention taking into account the Main principle mentioned can be realized, according to it it is sufficient if there is a locking part at one end of the insulation board located in a recess at the other end of the adjacent one Insulation board can be used so that it is a certain when inserted Overcome resistance, which on the other hand ensures that the insulation board in question is not from its mounting position automatically slips out again, in which the recess with the locking lug or those shown in the figures forms two latches for the locking part itself if there is still a certain mobility, in particular the pivotability of the two insulation boards in relation to each other is possible.

Fig. 3 ist ein Beispiel für eine solche Ausbildung der Erfindung, bei der die Dämmplattenenden 10, 11 nur jeweils an einer Seite la 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 la 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, 15 auf, die auch parallel zu den Außenseiten 1a, 1b der Dämmplatten 1 verlaufen.3 is an example of such an embodiment of the invention, in which the insulation board ends 10, 11 only on one side la are provided with inclined surfaces 5, 6 which are separated by a shoulder 12, 13 to either the locking lug 8 in front of the recess 2 or Guide constriction 7a in front of locking part 4. The locking part 4 has this training only on the one outside la of the insulation board 1 facing side one via the constriction 7a or Locking lug 8 on the projecting edge 9, when mounting on this must be pushed or pushed under compression. On the opposite sides, the ends 10, 11 are parallel Sliding surfaces 14, 15, which are also parallel to the outer sides 1a, 1b of the insulation boards 1 run.
