Description

Die Erfindung betrifft eine Wärmedämmplatte aus Kunststoff nach dem Oberbegriff des Anspruchs 1.The invention relates to a thermal insulation board made of plastic according to the preamble of claim 1.

Eine derartige Wärmedämmplatte ist aus der DE-A1-32 37 596 bekannt. Dort wird der Hohlraum durch eine hinterschnittene Nut gebildet, in der eine Feder einer benachbarten Wärmedämmplatte aufnehmbar ist. Die Feder hat an ihrem freien Ende eine Kopfleiste, die hinter die durch die Hinterschneidung gebildeten Flanken der ersten Wärmedämmplatte greift und die gegen den als Schaumkunststoffteil ausgebildeten, getrennt in der Nut aufnehmbaren, plattenförmigen Körper drücken kann. Von Nachteil ist jedoch, daß der Schaumkunststoffkörper keine große Rückstellkraft entwickelt und daß sein Federweg verhältnismäßig klein ist, so daß nur eine geringe Ausgleichsmöglichkeit vorhanden ist, um Toleranzen der Raumbreite zwischen zwei Montageflächen auszugleichen, zwischen denen die Wärmedämmplatten angeordnet werden.Such a thermal insulation board is known from DE-A1-32 37 596. There the cavity is formed by an undercut groove in which a tongue an adjacent thermal insulation panel is receivable. The feather has on her free end of a header, behind those formed by the undercut The flanks of the first thermal insulation board engage and those against the foam plastic part trained, separately receivable in the groove, plate-shaped Body can push. The disadvantage, however, is that the foam plastic body no great restoring force developed and that its travel is proportional is small, so that there is little possibility of compensation to Compensate for tolerances of the room width between two mounting surfaces, between which the thermal insulation boards are arranged.

Wärmedämmplatten können zur Isolierung von Gebäuden und Gebäudeteilen, insbesondere von Dächern, gegen Kälte und Wärme verwendet werden und sind z.B. auch durch die DE-U1-7 906 823 bekannt. Die bekannten Körper können mit Gewebe, Fasern oder Folien kaschiert sein. Durch die Einschnitte, die senkrecht zur Plattenebene und parallel zu einer Stirnseite verlaufen, ist der Körper durch geringe Kräfte verformbar und zwischen Dachsparren leichter einpaßbar. Auch lassen sich dadurch der Schwund oder die thermische Kontraktion des Kunststoffmaterials und ungleiche Sparrenabstände ausgleichen, die sonst zu Kältebrücken an den Stoßfugen führen würden. Der Nachteil dieser bekannten Wärmedämmplatten besteht jedoch darin, daß für die Wärmedämmung nicht die gesamte Stärke des Körpers der Wärmedämmplatte zur Verfügung steht. Durch die Einschnitte ist für die wirksame Wärmedämmung nur der Abstand zwischen zwei entgegegesetzten Einschnitten maßgebend, und dieser Abstand ist viel geringer als die Stärke der Wärmedämmplatte. Ferner ist nachteilig, daß die bekannten Einschnitte nur in geringem Mäß den erwähnten Ausgleich zulassen.Thermal insulation boards can be used to insulate buildings and parts of buildings, used especially on roofs, against cold and heat and are e.g. also known from DE-U1-7 906 823. The well-known body can be laminated with fabric, fibers or foils. Through the incisions, that run perpendicular to the plate plane and parallel to one end face is the Body deformable due to low forces and lighter between rafters adaptable. This also allows shrinkage or thermal contraction compensate for the plastic material and uneven rafters, which would otherwise lead to cold bridges at the butt joints. The disadvantage of this known thermal insulation boards, however, is that for thermal insulation not the entire thickness of the body of the thermal insulation panel is available stands. Due to the incisions, only the is for effective thermal insulation The distance between two opposing cuts is decisive, and this Distance is much less than the thickness of the thermal insulation board. Further is disadvantageous that the known incisions only to a small extent the mentioned Allow compensation.

Die Aufgabe der Erfindung besteht daher darin, eine Wärmedämmplatte der im Oberbegriff des Anspruchs 1 genannten Art zu schaffen, bei der die Wärmedämmung und die Ausgleichsmöglichkeit erhöht und verbessert werden.The object of the invention is therefore to provide a thermal insulation board in Preamble of claim 1 to create the type in which the thermal insulation and the possibility of compensation is increased and improved.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Man erkennt, daß die Erfindung jedenfalls dann verwirklicht ist, wenn in einer herkömmlichen Schaumstoffplatte im Zuge der Herstellung eines elastisch verformbaren Körpers ein Hohlraum geschaffen wird, in dem der Körper untergebracht ist, zumindest in einer Richtung durch auf Ober- oder Unterseite stehende Einschnitte oder auf Ober- und Unterseite gegeneinander versetzte Einschnitte elastisch verformbar ist und sein eines Ende sich bis zum offenen Ende des Hohlraums erstreckt. Dieses Ende kann dabei mit einem Steg einer benachbarten Wärmedämmplatte gleicher Art in Druckverbindung gebracht werden, so daß die abzudeckende Fläche inbezug auf vertikale Luftströmungen spaltfrei abdeckbar ist. Der Körper dient zugleich als Ausgleichsorgan, so daß das Zuschneiden der Wärmedämmplatte nicht mit absoluter Genauigkeit erfolgen muß.It can be seen that the invention is implemented in any case if in one conventional foam sheet in the course of producing an elastic deformable body is created a cavity in which the body is housed is, at least in one direction through on top or bottom standing incisions or offset against each other on the top and bottom Incisions is elastically deformable and its one end is open to the Extends end of the cavity. This end can be done with a web adjacent thermal insulation panel of the same type brought into pressure connection so that the area to be covered is related to vertical air currents can be covered without a gap. The body also serves as a balancing organ, so that the thermal insulation board is not cut with absolute accuracy got to.

Weitere zweckmäßige und vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor. Further expedient and advantageous embodiments of the invention go from the subclaims.

Durch die V-förmigen Einschnitte im Körper wird ein größerer Federweg hergestellt, so daß eine entsprechend vergrößerte Ausgleichsmöglichkeit geschaffen ist, um die Toleranzen der Raumbreite zwischen Dachsparren oder sonstige zu Kältebrücken führende Sachverhalte auszugleichen. Die Wärmedämmung wird dadurch erhöht, daß nun außer dem Körper die den Hohlraum bildenden Plattenwände zusätzlich vorgesehen sind.The V-shaped incisions in the body make it bigger Made travel, so that a correspondingly enlarged Compensation is created to the tolerances the space between rafters or others Compensate cold-leading issues. The Thermal insulation is increased by the fact that now outside the body the plate walls forming the cavity are additionally provided are.

Die Federwirkung wird dann optimal, wenn nach einer weiteren Ausbildung der Erfindung die V-förmigen Einschnitte so geführt werden, daß ein zickzack- oder wellenförmiges Band von im wesentlichen gleichbleibender Stärke entsteht.The spring action is optimal if after another Formation of the invention the V-shaped incisions so be performed that a zigzag or wavy band of essentially constant strength.

Gemäß einer weiteren Ausbildung der Erfindung ist der Steg auf der geschlossenen Schmalseite der Wärmedämmplatte angeformt und abbrechbar ausgebildet. Auf diese Weise ist die Wärmedämmplatte immer komplett vorhanden, und der Steg braucht nicht extra gefertigt und angeliefert werden. Sollen mehrere Wärmedämmplatten aneinandergereiht werden, so kann jeweils der Steg der einen Wärmedämmplatte in die Öffnung der nächsten Wärmedämmplatte eingesetzt werden, wobei der Steg der ersten Wärmedämmplatte abgebrochen und in die Öffnung der letzten Wärmedämmplatte eingesetzt wird. Auf diese Weise kann Abfall vermieden werden.According to a further embodiment of the invention, the web is on the closed narrow side of the thermal insulation board molded and designed to be breakable. That way the thermal insulation panel is always fully present, and the web does not need to be specially manufactured and delivered. Should several thermal insulation panels can be strung together, so in each case the web of one thermal insulation board into the opening the next thermal insulation board, the Web of the first thermal insulation board broken off and into the Opening of the last thermal insulation panel is used. On this way waste can be avoided.

Um die Verlegung der Wärmedämmplatten einfacher zu gestalten, weisen der Körper an seiner zur Öffnung hin liegenden Schmalseite und der Steg an seiner der Anformungstelle gegenüberliegenden Seite Ausbildungen für eine Nut-Feder-Verbindung auf. Die Nut-Feder-Verbindung hält den Steg am Körper fest, so daß er während der Verlegung der Wärmedämmplatte nicht verlierbar ist. Sollen mehrere Wärmedämmplatten aneinandergereiht werden, so wird mit den Nut-Feder-Verbindungen ein Zusammenhalt der Wärmedämmplatten möglich.To make laying the thermal insulation boards easier, point the body at its lying towards the opening Narrow side and the web at its the molding point opposite side training for a tongue and groove connection on. The tongue and groove connection keeps the web on Body firmly so that during the laying of the Thermal insulation board is not lost. Should be several Thermal insulation boards are strung together, so with the Tongue and groove connections keep the thermal insulation panels together possible.

Um die Festigkeit der Nut-Feder-Verbindung des Stegs mit dem Körper zu erhöhen, sind nach einer weiteren Ausbildung der Erfindung die Ausbildungen der Nut-Feder-Verbindung schwalbenschwanzförmig. Dadurch können auch ganze Wände aus Wärmedämmplatten auf einmal verlegt und kraftschlüssig miteinander verbunden werden.To the strength of the tongue and groove connection of the web with to increase the body are after further training the invention, the training of the tongue and groove connection dovetail-shaped. This can also cover entire walls laid from thermal insulation panels at once and non-positively be connected to each other.

Bei der Herstellung der Wärmedämmplatte wird in vorteilhafter Weise so verfahren, daß eine Vorrichtung mit mindestens einem beheizbaren Drahtstück verwendet wird, das den Körper aus einer Vollplatte zickzackförmig ausschneidet. Die Vorrichtung kann zwei beheizbare Drahtstücke aufweisen, von denen das eine Drahtstück die Oberseite des Körpers und das andere Drahtstück gleichzeitig die Unterseite des Körpers herstellt.In the manufacture of the thermal insulation board is advantageous Proceed in such a way that a device with at least a heated piece of wire is used that the body cut out from a solid board in a zigzag shape. The The device can have two heatable pieces of wire, one piece of wire the top of the body and the other piece of wire simultaneously the bottom of the Body produces.

Die Erfindung wird nun anhand von zwei Ausführungsbeispielen näher erläutert. Es zeigen:

In Fig. 1 ist eine quaderförmige Wärmedämmplatte 1 verkürzt dargestellt, die in Wirklichkeit in horizontaler Richtung eine deutlich größere Ausdehnung hat. Die Wärmedämmplatte 1 weist hier einen quaderförmigen Hohlraum 2 und auf einer Schmalseite 3 des Hohlraums 2 eine Öffnung 4 auf. Der Hohlraum 2 könnte allgemein auch oval oder keilförmig sein. Im Hohlraum 2 ist ein plattenförmiger Körper 5 angeordnet, der hier einstückig mit der Wärmedämmplatte 1 ausgebildet ist. Der Körper 5 kann jedoch auch von der Wärmedämmplatte 1 getrennt sein. Diese zwei Ausbildungsarten berühren das Herstellungsverfahren der Wärmedämmplatte. Im Körper 5 sind auf Oberseite und Unterseite V-förmige Einschnitte wie die Einschnitte 6, 6' vorgesehen, die gegeneinander versetzt geführt sind, so daß sich ein zickzackförmiges Band von im wesentlichen gleichbleibender Stärke ergibt. Ferner ist an der geschlossenen Schmalseite 8 der Wärmedämmplatte 1 ein quaderförmiger Steg 7 mittels einer Brücke angeformt, die an der Anformungsstelle 9 dargestellt ist. Der Steg 7 ist in seiner Breite so bemessen, daß er in die Öffnung 4 paßt und diese im Gleitsitz verschließen kann.In Fig. 1, a cuboid thermal insulation board 1 is shortened shown in reality in the horizontal direction has a much larger extension. The thermal insulation board 1 here has a cuboid cavity 2 and on one Narrow side 3 of the cavity 2 has an opening 4. The Cavity 2 could generally also be oval or wedge-shaped. A plate-shaped body 5 is arranged in the cavity 2, formed here in one piece with the thermal insulation board 1 is. However, the body 5 can also from the thermal insulation board 1 be separated. These two types of training touch that Manufacturing process of the thermal insulation board. There are 5 in the body V-shaped cuts on top and bottom like that Incisions 6, 6 'are provided which are offset from one another are guided so that a zigzag band of results in substantially constant strength. Further is on the closed narrow side 8 of the thermal insulation board 1 a rectangular web 7 is formed by means of a bridge, which is shown at the molding point 9. The jetty 7 is dimensioned in its width so that it in the opening 4 fits and can lock this in the sliding seat.

Die beschriebenen Teile der Wärmedämmplatte bestehen aus Kunststoff, vorzugsweise aus Schaumstoff wie Styropor. Der Körper 5 läßt sich aufgrund der V-förmigen Einschnitte 6, 6' in horizontaler Richtung elastisch verformen und besitzt daher einen großen Federweg. Bei der Verlegung der Wärmedämmplatte 1 wird der Steg 7 an der Anformungsstelle 9 abgebrochen und in die Öffnung 4 eingefügt. Der Steg 7 drückt dabei auf den Körper 5 und ragt je nach vorzunehmendem Ausgleich mehr oder weniger in den Hohlraum 2 hinein. Wenn die Wärmedämmplatte 1 zwischen Dachsparren verlegt wird, kann somit in einem weiten Bereich eine spaltlose Abdichtung erreicht werden.The parts of the thermal insulation board described consist of Plastic, preferably made of foam such as polystyrene. The Body 5 can be due to the V-shaped incisions 6, 6 'elastically deform in the horizontal direction and has therefore a large travel. When laying the Thermal insulation board 1 is the web 7 at the molding point 9 canceled and inserted into opening 4. The bridge 7 presses on the body 5 and protrudes depending on what needs to be done Compensation more or less into the cavity 2. If the thermal insulation board 1 is laid between rafters, can therefore provide a gapless seal in a wide range can be achieved.

Soll eine größere Fläche wärmeisoliert werden, so können mehrere der in Fig. 1 dargestellten Wärmedämmplatten zu einer Wärmedämmwand aneinandergereiht werden. In Fig. 2 sind einfachheitshalber nur zwei solcher Wärmedämmplatten 1, 1' gezeigt. Der Steg 7' der Wärmedämmplatte 1' wird in die Öffnung 4 der Wärmedämmplatte 1 eingebracht, während der Steg 7 der Wärmedämmplatte 1 abgebrochen und in die Öffnung 4' der Wärmedämmplatte 1' eingeführt wird. Auch hierbei kann die Breite der Wärmedämmwand in weiten Grenzen verändert werden.If a larger area is to be thermally insulated, then several of the thermal insulation panels shown in Fig. 1 be lined up in a thermal insulation wall. In Fig. 2 are just two such thermal insulation boards for the sake of simplicity 1, 1 'shown. The web 7 'of the thermal insulation board 1' is in introduced the opening 4 of the thermal insulation board 1 while the web 7 of the thermal insulation board 1 broken off and into the Opening 4 'of the thermal insulation board 1' is inserted. Also the width of the thermal insulation wall can vary within wide limits to be changed.

In Fig. 3 ist eine abgeänderte, aber der Fig. 1 ähnelnde Wärmedämmplatte dargestellt, so daß nur die abweichenden Merkmale beschrieben werden. Der Steg 7 hat hier eine größere Länge. Der Körper 5 und der Steg 7 weisen Ausbildungen 12, 13 für eine Nut-Feder-Verbindung auf. Der Körper 5 ist an seiner zur Öffnung 4 hin liegenden Schmalseite 10 mit einer schwalbenschwanzförmigen Nut 12 versehen, während der Steg 7 an seiner der Anformungsstelle 9 gegenüberliegenden Seite 11 eine an die Nut 12 angepaßte, schwalbenschwanzförmige Schiene 13 aufweist, die an den Steg 7 angeformt ist. Der abgebrochene Steg 7 wird mit seiner Schiene 13 in einer zur Zeichnungsebene senkrechten Richtung in die Nut 12 eingeführt und ist somit gegen Herausfallen gesichert. Die Nut-FederVerbindung 12, 13 kann aber auch in anderer Weise ausgebildet sein. 3 is a modified one, but similar to FIG. 1 Thermal insulation board shown, so that only the deviating Features are described. The web 7 has a larger one here Length. The body 5 and the web 7 have designs 12, 13 for a tongue and groove connection. The body 5 is on its narrow side 10 facing the opening 4 with a dovetail-shaped groove 12 provided during the web 7 on its side opposite the molding point 9 11 a dovetail-shaped adapted to the groove 12 Has rail 13 which is integrally formed on the web 7. The broken web 7 is with its rail 13 in one direction perpendicular to the plane of the drawing into the groove 12 introduced and is thus secured against falling out. The Tongue-and-groove connection 12, 13 can also in other ways be trained.

Sollen mehrere Wärmedämmplatten der in Fig. 3 dargestellten Art aneinandergereiht werden, so wird mit Bezug auf Fig. 4 der Steg 7 der ersten Wärmedämmplatte abgebrochen und in die Öffnung 4' der letzten Wärmedämmplatte eingebracht, wobei die Schiene 13 in die Nut 12' eingeführt wird. Die Wärmedämmplatten werden dadurch miteinander verbunden, daß jeweils der Steg 7' einer Wärmedämmplatte in die Öffnung 4 der benachbarten Wärmedämmplatte eingebracht wird, wobei die Schiene 13' in die Nut 12 eingeführt wird. Auf diese Weise können ganze Wärmedämmwände fest zusammengehalten werden.If several thermal insulation panels are shown in Fig. 3 Kind are strung together, so with reference to Fig. 4 the web 7 of the first thermal insulation board is broken off and placed in the opening 4 'of the last thermal insulation panel, the rail 13 is inserted into the groove 12 '. The Thermal insulation boards are connected to each other in that each of the web 7 'of a thermal insulation board in the opening 4 of the adjacent thermal insulation board is introduced, wherein the rail 13 'is inserted into the groove 12. To this In this way, entire thermal insulation walls can be held together become.

Wie bereits erwähnt, kann der Körper 5 ein vom übrigen Teil der Wärmedämmplatte 1 getrenntes Teil sein. In diesem Fall kann die Wärmedämmplatte dadurch hergestellt werden, daß zwei Formen verwendet werden, eine für den Körper 5 und eine für den übrigen Teil der Wärmedämmplatte, und daß der Kunststoff in diesen Formen ausgeschäumt wird.As already mentioned, the body 5 can be one of the remaining part the thermal insulation panel 1 be a separate part. In this case the thermal insulation board can be manufactured in that two forms are used, one for the body 5 and one for the remaining part of the thermal insulation board, and that the Plastic is foamed in these forms.

Bei den in den Figuren dargestellten Ausführungen ist der Körper 5 aber vorteilhafterweise mit dem übrigen Teil der Wärmedämmplatte einstückig verbunden. Die Herstellung dieser Wärmedämmplatte kann so erfolgen, daß der Körper 5 aus einer in einer Form ausgeschäumten Vollplatte ausgeschnitten wird. Zum Ausschneiden kann eine Vorrichtung verwendet werden, die mit einem beheizbaren Drahtstück ausgestattet ist. Mit dem Drahtstück kann der Körper 5 zickzackförmig ausgeschnitten werden. Die Vorrichtung kann rechnergesteuert sein. In the embodiments shown in the figures, the Body 5 but advantageously with the rest of the Thermal insulation panel connected in one piece. The making of this Thermal insulation board can be done so that the body 5 from a is cut out in a form of foamed full panel. A device can be used for cutting out which is equipped with a heated piece of wire. With the wire piece, the body 5 can zigzag be cut out. The device can be computer controlled his.

Die Vorrichtung kann vorteilhafterweise jedoch auch mit zwei beheizbaren Drahtstücken ausgestattet sein, von denen das eine die Oberseite des Körpers 5 und das andere gleichzeitig die Unterseite des Körpers 5 herstellt. Dadurch kann die Wärmedämmplatte schneller gefertigt werden.However, the device can also advantageously be used two heated pieces of wire, one of which one the top of the body 5 and the other produces the underside of the body 5 at the same time. Thereby the thermal insulation board can be manufactured faster.
