Description

Die Erfindung betrifft ein Wärmedämmelement zur Wärmeentkopplung zwischen Wandteilen und Boden- oder Deckenteilen, mit der Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a thermal insulation element for heat decoupling between wall parts and floor or ceiling parts, having the features of the preamble of claim 1.

Eine in wärmeschutztechnischer Hinsicht kritische Stelle stellt der Mauerfußbereich an Gebäudesockeln dar. Denn dort wird die Wärmedämmung der Außenwand und der Kellerdecke durch das aufgehende Mauerwerk unterbrochen. Mit dem mauersteinförmigen Wärmedämmelement der eingangs genannten Art ist jedoch die Verbindung zweier widersprüchlicher Eigenschaften gelungen: Starke Wärmedämmung bei gleichzeitig hoher Tragfähigkeit. So wird die Lücke in der Wärmedämmung der Gebäudehülle geschlossen, eine Problemstelle, die bislang auch mit hohem Aufwand nur unbefriedigend gelöst werden konnte. Im Übrigen müssen aber die Boden- oder Deckenteile, die durch ein Wärmedämmelement wämetechnisch entkoppelt werden sollen, nicht zwangsläufig Boden- oder Deckenplatten sein, sondern können beispielsweise auch aus Streifenfundamenten oder dergleichen bestehen.A critical point in terms of thermal protection is the wall footing on building pedestals. This is where the thermal insulation of the outer wall and the basement ceiling is interrupted by the rising masonry. However, the combination of two contradictory properties has been achieved with the brick-shaped thermal insulation element of the type mentioned at the outset: strong thermal insulation combined with high load capacity. Thus, the gap in the thermal insulation of the building envelope is closed, a problem that could be resolved so far only with great effort unsatisfactory. Incidentally, but the floor or ceiling parts that are to be decoupled by a thermal insulation wämetechnisch not necessarily be floor or ceiling panels, but may for example consist of strip foundations or the like.

Das mauersteinförmige Wärmedämmelement lässt sich wie ein herkömmlicher Mauerstein als erste Steinschicht der tragenden Wand oberhalb der Kellerdecke einsetzen. Auf eine derartige Einbausituation beziehen sich im Übrigen auch die Begriffe "obere" und "untere" Tragfläche, wie auch die im Weiteren dieser Anmeldung benutzten Richtungsangaben.The brick-shaped thermal insulation element can be used as a conventional brick as the first stone layer of the load-bearing wall above the basement ceiling. Incidentally, the terms "upper" and "lower" airfoil also refer to such an installation situation, as does the directional information used in the remainder of this application.

Wird die Wärmedämmung unterhalb der Kellerdecke angebracht, so erfolgt der Einbau einfach als letzte Steinschicht des Kellermauerwerks. Ablängen kann man das Wärmedämmelement mit der Steinsäge oder Trennscheibe. Man setzt das einbaufertige Dämmelement einfach auf ein Mörtelbett und schließt damit die verbleibende Lücke zwischen Außendämmung und Kellerdeckendämmung. Dadurch erhöht sich die Oberflächentemperatur auf einen unkritischen Wert. Außerdem verhindert das Wärmedämmelement auch kapillares Saugen zuverlässig. Ebenso werden Vertikal- und Horizontalkräfte sicher übertragen. Das mauersteinförmige Wärmedämmelement löst somit ohne großen Aufwand das Wärmebrückenproblem im Bereich des Gebäudesockels.If the thermal insulation is installed below the basement ceiling, the installation is simply the last stone layer of the cellar masonry. You can cut to length the thermal insulation element with the stone saw or cutting disc. You put the ready to install Insulating element simply on a mortar bed and thus closes the remaining gap between external insulation and basement ceiling insulation. This increases the surface temperature to a non-critical value. In addition, the thermal insulation element reliably prevents capillary suction. Likewise, vertical and horizontal forces are transmitted safely. The brick-shaped thermal insulation element thus solves the thermal bridge problem in the area of the building base without much effort.

Aus der DE 199 42 965 ist ein mauersteinförmiges Wärmedämmelement bekannt, das aus säulenförmigen Tragelementen besteht, die von einem wärmedämmenden Isolierelement umgeben sind.From DE 199 42 965 a brick-shaped thermal insulation element is known, which consists of columnar support elements which are surrounded by a heat-insulating element.

Die Herstellung dieser Wärmedämmelemente ist allerdings aufgrund der Vielzahl von säuleäförmigen Tragelementen fertigungstechnisch verhältnismäßig aufwendig, insbesondere weil das Isolierelement als Gießform für die Tragelemente dient und entsprechend vorgefertigt werden muss. Weiter besteht bei dieser Ausbildung der Wärmedämmelemente die Gefahr eines Knickens der Säulen, beispielsweise wenn horizontale Schubkräfte angreifen. Die CH-A-689022 offenbart ein Wärmedämmelement, das die Merkmale des Oberbegriffes des Anspruchs 1 aufweist.However, the production of these thermal insulation elements is relatively expensive due to the large number of columnar support elements manufacturing technology, especially because the insulating element serves as a mold for the support elements and must be prefabricated accordingly. Further, in this embodiment of the thermal insulation elements there is a risk of buckling of the columns, for example when horizontal shear forces are applied. CH-A-689022 discloses a thermal barrier element having the features of the preamble of claim 1.

Ausgehend von diesem Stand der Technik ist es daher Aufgabe der vorliegenden Erfindung, ein mauersteinförmiges Wärmedämmelement der eingangs genannten Art weiterzubilden, das zumindest einen der genannten Nachteile vermeidet.Based on this prior art, it is therefore an object of the present invention to develop a brick-shaped thermal insulation element of the type mentioned, which avoids at least one of the disadvantages mentioned.

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

Erfindungsgemäß besteht ein balkenförmiges Tragelement auch in dem Horizontalquerschnitt aus einem Längsstreifen, wobei dann das mauersteinförmige Wärmedämmelement mehrere dieser Längsstreifen aufweist.According to the invention, a beam-shaped support element also consists of a longitudinal strip in the horizontal cross-section, in which case the brick-shaped heat-insulating element has a plurality of these longitudinal strips.

Hierbei beziehen sich die Begriffe "längs" und "quer" im Übrigen auf die Haupterstreckungsrichtung des mauersteinförmigen Wärmedämmelements. Durch die große bzw. die großen zusammenhängenden Auflageflächen des Tragelements wird eine hohe Druckfestigkeit des mauersteinförmigen Wärmedämmelementes erzielt sowie horizontalen Schubkräften ein optimaler Widerstand entgegengesetzt. Eine Optimierung der Tragelement- und Isolierelementmaterialien und -querschnitte ermöglicht dann bei gegebenen Anforderungen an die Festigkeit des Wärmedämmelements eine besonders hohe Wärmedämmung. Schließlich ist das mauersteinförmige Wärmedämmelement kostengünstig und einfach zu fertigen.Incidentally, the terms "longitudinal" and "transverse" refer to the main extension direction of the brick-shaped thermal insulation element. Due to the large or the large contiguous bearing surfaces of the support element, a high compressive strength of the brick-shaped thermal insulation element is achieved as opposed to horizontal shear forces optimal resistance. An optimization of Tragelement- and Isolierelementmaterialien and cross-sections then allows for given requirements on the strength of the thermal insulation element a particularly high thermal insulation. Finally, the brick-shaped thermal insulation element is inexpensive and easy to manufacture.

Das Tragelement ist im Vertikalquerschnitt in etwa rechteckig - insbesondere quadratisch ausgebildet, wobei es denkbar ist, die Ecken abzurunden. Im dem Horizontalquerschnitt ist das Tragelement ebenfalls rechteckig ausgeführt. Die Ecken können ebenfalls abgerundet sein. Insgesamt ergibt sich daher in dreidimensionaler Betrachtung die balkenförmige Ausbildung des Tragelements.The support element is approximately rectangular in vertical cross section - in particular square, wherein it is conceivable to round off the corners. In the horizontal cross section, the support element is also rectangular. The corners can also be rounded. Overall, therefore, results in three-dimensional view, the beam-shaped design of the support element.

Die Flächenform der oberen und/oder der unteren Tragfläche des Tragelements stimmt mit der Flächenform des Tragelements im besagten Horizontalquerschnitt überein. Dies ist bei der Quaderform des Tragelements der Fall, die eine besonders einfach zu fertigende Bauform mit geringer Knickanfälligkeit darstellt.The surface shape of the upper and / or the lower support surface of the support element coincides with the surface shape of the support element in the said horizontal cross section. This is the case with the cuboid shape of the support element, which represents a particularly easy-to-manufacture design with low buckling resistance.

Des weiteren bildet das lsolierelement die seitlichen Außenflächen des Wärmedämmelementes und liegt zumindest überwiegend, insbesondere ganzflächig an den Seitenflächen der Tragelemente an. Damit ist unter anderem gewährleistet, dass das mauersteinförmige Dämmelement in seiner gesamten Breite und Höhe eine optimale Isolierwirkung erzielt.Furthermore, the insulating element forms the lateral outer surfaces of the thermal insulation element and is at least predominantly, in particular over the entire surface of the side surfaces of the support elements. This ensures, inter alia, that the brick-shaped insulating element achieved in its entire width and height optimum insulation.

Zweckmäßig liegt das Isolierelement nicht nur zumindest überwiegend an den Tragelementen an, sondern ist mit diesem verbunden, beispielsweise mit dessen Seitenflächen.Suitably, the insulating element is not only at least predominantly on the support elements, but is connected to this, for example, with its side surfaces.

Weiter kann das Isolierelement einen einstückigen Körper bilden. Dies bietet unter anderem den Vorteil, dass das isolierelement beim Einsatz entsprechender Materialien ausreichend Stabilität aufweist, um als verlorene Schalung für die aus Leichtbeton oder ähnlichen Materialien zu gießenden Tragelemente zu dienen. Dabei kann das Isolierelement aus offenporigem Material gebildet sein, in das der Werkstoff der Tragelemente beim Gießen zumindest teilweise eindringt und mit dem der Werkstoff nach dessen Aushärten einen formschlüssigen Verbund eingeht. Dieser Verbund kann aber auch dadurch erzielt werden, dass das Isolierelement tragelementseitig profiliert ist. Gegenüber einer auch im Rahmen der Erfindung liegenden Verklebung des lsolierelements mit den Tragelement en bieten derartige Möglichkeiten eines Verbundes ein erhöhtes Maß an Verbindungssicherheit. Im Übrigen entfällt der separate Vorgang des Verklebens.Further, the insulating member may form a one-piece body. This offers, inter alia, the advantage that the insulating element has sufficient stability when using appropriate materials to serve as a lost formwork for the lightweight concrete or similar materials to be poured supporting elements. In this case, the insulating member may be formed of open-cell material, in which at least partially penetrates the material of the support elements during casting and with which the material enters into a positive connection after its curing. But this composite can also be achieved by the fact that the insulating element is profiled on the support element side. Compared with a bonding within the scope of the invention of the insulating element with the support element, such possibilities of a composite offer an increased degree of connection security. Incidentally, the separate process of gluing is omitted.

Zweckmäßigerweise besteht das Isolierelement aus Polystyrol, das geeignete Dämmwerte aufweist und eine ausreichende Stabilität besitzt, so dass es möglich ist, einen zusammenhängenden Körper zu bilden, der in der oben beschriebenen Weise als verlorene Schalung dienen kann. Es liegt aber auch im Rahmen der Erfindung, Isolierelemente vorzusehen, die im Wesentlichen bzw. zum Großteil aus Luft bestehen. Insbesondere, wenn das Tragelement die Luft seitlich rahmenartig einfasst, kann zusätzlich vorgesehen werden, die Luft auch von oben und unten, etwa durch Deckel oder Ähnliches, einzuschließen, so dass beim Einbau des Wärmedämmelements kein von oben/unten eindringender Mörtel etc. die Luft verdrängen kann. Die Tragelemente können auch jeweils einstückig mit innen liegendem, vollständig von diesem eingeschlossenem Hohlraum vorgesehen werden.Conveniently, the insulating member is made of polystyrene, which has suitable insulation values and has sufficient stability, so that it is possible to form a coherent body, which can serve as a lost formwork in the manner described above. However, it is also within the scope of the invention to provide insulating elements which essentially or largely consist of air. In particular, if the support member encloses the air laterally like a frame, can also be provided to include the air from above and below, such as by covers or the like, so that when installing the heat-insulating element from above / below penetrating mortar, etc. displace the air can. The support elements can also each be provided in one piece with an inner, completely enclosed by this cavity.

Außerdem ist erfindungsgemäß vorgesehen, dass das Isolierelement eine oder mehrere Zwischenwände aufweist, die die Tragelemente von oben nach unten, insbesondere vertikal zumindest teilweise voneinander trennen. Das Isolierelement bildet in diesem Fall das Gerüst für das mauersteinförmige Wärmedämmelement, das im Inneren zwei voneinander getrennte Tragelemente aufweist.In addition, the invention provides that the insulating element has one or more partitions that separate the support elements from top to bottom, in particular vertically at least partially from each other. The insulating element forms the framework for the brick-shaped in this case Heat insulation element having two separate support elements inside.

Die Zwischenwand kann dabei das Isolierelement mittig teilen. Dadurch ergibt sich insbesondere eine Symmetrie im Aufbau des Wärmedämmelementes, die sowohl fertigungstechnisch als auch aus Stabilitätsgründen vorteilhaft ist. Es liegt in diesem Zusammenhang auch im Rahmen der Erfindung, anstelle einer Zwischenwand des Isolierelements eine isolierende Luftschicht vorzusehen.The intermediate wall can share the insulating centrally. This results in particular a symmetry in the structure of the thermal insulation element, which is advantageous both manufacturing technology and stability reasons. It is in this context also in the context of the invention to provide an insulating air layer instead of an intermediate wall of the insulating.

Vorteilhafterweise können über die Verhältnisse zwischen den Dicken der Isolierelementwände und den Tragelementdicken verschiedenste Werte für die Druckfestigkeit und die Wärmeleitfähigkeit des Wärmdämmelementes eingestellt werden.Advantageously, a wide variety of values for the compressive strength and the thermal conductivity of the thermal insulation element can be set via the relationships between the thicknesses of the insulating element walls and the support element thicknesses.

Um einen möglichst weit außen liegenden Tragelemente-Flächenschwerpunkt zu erhalten, ist die Dicke der Zwischenwand bzw. Zwischenwände des Isolierelements größer als die Dicke dessen äußerer Längsseiten ausgebildet.In order to obtain as far as possible outward support elements-centroid, the thickness of the intermediate wall or partitions of the insulating is greater than the thickness of the outer longitudinal sides formed.

Es wurde gefunden, dass ein besonders günstiges Dickenverhältnis dann vorliegt, wenn die Dicke der Zwischenwand in etwa doppelt so groß ist wie die Dicke der äußeren Längsseiten des Isolierelements. Natürlich sind auch beliebige andere Dickenverhältäisse denkbar.It has been found that a particularly favorable thickness ratio exists when the thickness of the intermediate wall is approximately twice as large as the thickness of the outer longitudinal sides of the insulating element. Of course, any other Dickenverhältäisse are conceivable.

Was die Zwischenwand bzw. -wände des lsolierelements angeht, so ist/sind diese vorteilhafterweise von Öffnungen durchbrochen, wobei an die Tragelemente angeformte Verbindungsstege diese Öffnungen durchgreifen. Diese Verbindung der einzelnen Tragelemente gewährleistet insbesondere eine hohe Stabilität des gesamten Wärmedämmelements.As regards the intermediate wall or walls of the insulating element, these are / are advantageously pierced by openings, wherein connecting webs integrally formed on the supporting elements pass through these openings. This connection of the individual support elements ensures in particular a high stability of the entire heat-insulating element.

Die Tragelemente selbst sind zweckmäßigerweise aus Leichtbeton gebildet, Leichtmörtel oder nicht-mineralischem Material wie z. B. Kunststoff gebildet.The support elements themselves are suitably made of lightweight concrete, light mortar or non-mineral material such. B. plastic formed.

Besonders zweckmäßig ist es, wenn die Tragelementean der oberen und/oder unteren Last aufnehmenden Tragfläche profiliert sind. Dadurch kann ein besonders fester, Horizontalkräfte optimal aufnehmender und übertragender Verbund des mauersteinförmigen Wärmedämmelementes mit dem Wandteil einerseits und dem Boden- oder Deckenteil andererseits erzielt werden, wenn sich als Verbindungsmaterial eingesetzter Mörtel mit diesen Profilierungen formschlüssig verbindet. Ein guter Verbund kann auch dadurch bewirkt werden, dass die Tragelemente aus offenporigem Material bestehen.It is particularly expedient if the support elements are profiled on the upper and / or lower load receiving wing. This allows a particularly strong, horizontal forces optimally receiving and transmitting composite of brick-shaped thermal insulation element with the wall part on the one hand and the floor or ceiling part on the other hand be achieved when used as a bonding material mortar with these profiles positively connects. A good bond can also be effected by the fact that the support elements made of open-pored material.

Figur 1 stellt ein kastenförmiges, wärmedämmendes Isolierelement 1 eines in Figur 3 dargestellten mauersteinförmigen Wärmedämmelementes 2 in perspektivischer Seitenansicht dar. Das Wärmedämmelement 2 ist dabei in der Orientierung dargestellt, in der es später auch zwischen einem Wandteil und einem Boden/Deckenteil eines Gebäudes eingebaut wird.1 shows a box-shaped, insulating insulating element 1 of a brick-shaped thermal insulation element 2 shown in Figure 3 in a perspective side view. The thermal insulation element 2 is shown in the orientation in which it is later also installed between a wall part and a floor / ceiling part of a building.

Das Isolierelement 1 besteht aus zwei parallel zueinander verlaufenden Längsseiten 2a, 2b, einer Zwischenwand 3 und zwei sich an die Längsseiten 2a, 2b anschließende, senkrecht zu diesen verlaufende und sich parallel gegenüberstehende Stirnseiten 4a, 4b.The insulating element 1 consists of two mutually parallel longitudinal sides 2a, 2b, an intermediate wall 3 and two adjoining the longitudinal sides 2a, 2b, perpendicular to these extending and parallel opposite end faces 4a, 4b.

Die mit den Stirnseiten 4a, 4b verbundene, parallel zu den Längsseiten 2a, 2b verlaufende Zwischenwand 3 unterteilt dabei das Isolierelement 1 mittig in zwei symmetrische Hälften 5a, 5b die zur Aufnahme von zwei balkenförmigen, druckfesten Tragelementen 6a, 6b dienen, die in Figur 2 dargestellt sind.The connected to the end faces 4a, 4b, parallel to the longitudinal sides 2a, 2b extending intermediate wall 3 divides the insulating element 1 centrally in two symmetrical halves 5a, 5b which serve to receive two bar-shaped, pressure-resistant support elements 6a, 6b, which are shown in FIG.

Da die Zwischenwand 3 das Isolierelement 1 mittig teilt, trifft sie natürlicherweise die beiden Stirnseiten 4a, 4b in deren Mitten.Since the intermediate wall 3 divides the insulating element 1 centrally, it naturally meets the two end faces 4a, 4b in their middle.

In Figur 2 sind die zwei balkenförmigen Tragelemente 6a, 6b aus Leichtbeton in perspektivischer Seitenansicht dargestellt. Deutlich zu erkennen sind die Last aufnehmenden, rechteckigen oberen Tragflächen 9a, 10a. Nicht zu erkennen sind dagegen die unteren, rechteckigen Tragflächen 9b, 10b.In Figure 2, the two beam-shaped support members 6a, 6b made of lightweight concrete in a perspective side view are shown. Clearly visible are the load-receiving, rectangular upper wings 9a, 10a. Not visible, however, are the lower, rectangular wings 9b, 10b.

Figur 3 (a) zeigt das komplette Wärmedämmelement 2, das aus dem Isolierelement 1 und den Tragelementen 6a, 6b gebildet ist, in einem Vertikalquerschnitt. In diesem Vertikalquerschnitt sind die Tragelemente 6a, 6b rechteckig ausgebildet, wobei allerdings auch andere Formen, wie etwa eine Kelchform oder eine Quadratform denkbar sind.FIG. 3 (a) shows the complete thermal insulation element 2, which is formed from the insulating element 1 and the support elements 6a, 6b, in a vertical cross section. In this vertical cross section, the support elements 6a, 6b are rectangular, although other shapes, such as a cup shape or a square shape are conceivable.

Figur 3 (b) stellt einen Horizontalquerschnitt entlang der Linie I-I der Figur 3 (a) dar, wobei der Horizontalquerschnitt zwischen den oberen Tragflächen 9a, 10a und den unteren Tragflächen 9b, 10b verläuft.Figure 3 (b) illustrates a horizontal cross-section along the line I-I of Figure 3 (a), with the horizontal cross-section extending between the upper wings 9a, 10a and the lower wings 9b, 10b.

Wichtig ist nun, dass die Tragelemente 6a, 6b in diesem Horizontalquerschnitt jeweils als Streifen ausgebildet sind und zwar als rechteckige Längsstreifen bezogen auf die Haupterstreckungsrichtung des Wärmedämmelements 2. Es ist allerdings auch denkbar, diese Streifen nicht exakt rechteckig sondern beispielsweise geschwungen auszubilden, wobei die Ecken abgerundet sein können.It is also important that the support elements 6a, 6b are formed in this horizontal cross section in each case as strips and as rectangular longitudinal strips based on the main extension direction of the heat-insulating element 2. However, it is also conceivable that these strips not exactly rectangular but, for example, curved form, the corners can be rounded.

Die Flächenform der Tragelemente 6a, 6b im Horizontalquerschnitt 3 (b), d.h. die Rechteckform, stimmt im Übrigen mit der Flächenform der Tragflächen 9a, 9b, 10a, 10b überein. Insgesamt ergibt sich eine besonders günstige Balkenform der Tragelemente 6a, 6b.The surface shape of the support members 6a, 6b in the horizontal cross section 3 (b), i. the rectangular shape, coincides otherwise with the surface shape of the wings 9a, 9b, 10a, 10b match. Overall, a particularly favorable beam shape of the support elements 6a, 6b results.

Das Isolierelements 1 ist aus Polystyrol hergestellt, wobei natürlich auch andere Materialien eingesetzt werden können, die eine ausreichende Isoliereigenschaft besitzen.The insulating member 1 is made of polystyrene, of course, other materials can be used, which have a sufficient insulating property.

Die Tragelemente 6a, 6b werden im Normalfall in der Weise gefertigt, dass das Isolierelement 1 der Figur 1 als verlorene Schalung dient und in diese Schalung Leichtbeton in flüssigem Zustand gegossen wird. Dieser Leichtbeton dringt dann zumindest teilweise in die jeweiligen nach innen gerichteten Seiten der Wände 2a, 2b, 3, 4a, 4b des Isolierelementes 1 ein und geht mit diesen nach dem Aushärten einen formschlüssigen Verbund ein.The support elements 6a, 6b are normally made in such a way that the insulating element 1 of Figure 1 serves as a permanent formwork and is poured into this formwork lightweight concrete in the liquid state. This lightweight concrete then penetrates at least partially into the respective inwardly directed sides of the walls 2 a, 2 b, 3, 4 a, 4 b of the insulating element 1 and, after hardening, forms a positive connection with these.

Es ist aber auch denkbar, dass die balkenförmigen Tragelemente 6a, 6b separat gefertigt werden und dann in die Hälften 5a, 5b des Isolierelementes 1 eingesetzt werden. Eine Verbindung zwischen dem Isolierelement und den Tragelementen kann dann dadurch erreicht werden, dass diese an den Innenwänden des Isolierelementes angeklebt werden.However, it is also conceivable that the bar-shaped support elements 6a, 6b are manufactured separately and then inserted into the halves 5a, 5b of the insulating element 1. A connection between the insulating element and the support elements can then be achieved in that they are adhered to the inner walls of the insulating element.

Deutlich zu erkennen sind die äußeren Seitenflächen 2a, 2b des Isolierelementes 1, die die Außenflächen des Wärmedämmelementes bilden, vollständig an den Seitenflächen der Tragelemente 6a, 6b anliegen, die Seitenflächen bedecken und mit diesen verbunden sind. Die oberen und unteren Tragflächen 9a, 9b, 10a, 10b sind dagegen nicht von dem Isolierelement 1 überdeckt.Clearly visible are the outer side surfaces 2a, 2b of the insulating element 1, which form the outer surfaces of the thermal insulation element, completely abut the side surfaces of the support members 6a, 6b, cover the side surfaces and are connected thereto. The upper and lower wings 9a, 9b, 10a, 10b, however, are not covered by the insulating member 1.

Weiter ist die Mittelwand 3 zu erkennen, deren Dicke zur Erzielung eines möglichst weit außen liegenden Tragelemente-Flächenschwerpunkts in etwa doppelt so groß ist wie die Dicke der äußeren Längsseiten 2a, 2b. Natürlich ist auch eine Vielzahl von anderen Dickenverhältnissen denkbar.Next, the center wall 3 can be seen, the thickness of which is about twice as large as the thickness of the outer longitudinal sides 2a, 2b in order to achieve a support element area center of gravity as far as possible. Of course, a variety of other thickness ratios is conceivable.

Diese Mittelwand 3 kann im Übrigen mit Öffnungen durchsetzt sein, durch die Stege durchgreifen können, die die Tragelemente 6a, 6b verbinden.Incidentally, this middle wall 3 can be penetrated with openings through which webs can pass which connect the support elements 6a, 6b.

Wichtig ist noch, dass über die Dickenverhältnisse zwischen den Isolierelementwänden 2a, 2b, 3 und den Tragelementen 6a, 6b verschiedenste Werte für die Druckfestigkeit und die Wärmeleitfähigkeit des Wärmdämmelementes 2 einstellbar sind.It is also important that various values for the compressive strength and the thermal conductivity of the thermal insulation element 2 can be set via the thickness ratios between the insulating element walls 2a, 2b, 3 and the support elements 6a, 6b.

Hervorzuheben ist außerdem die Symmetrie des Wärmedämmelementes 2, die eine besonders hohe Stabilität und Druckfestigkeit des Wärmedämmelementes 2 ermöglicht.Also to emphasize is the symmetry of the thermal insulation element 2, which allows a particularly high stability and compressive strength of the thermal insulation element 2.

Schließlich weist die rechte Stirnseite 4b des Isolierelementes 1 an ihrer Außenseite eine Reihe von Erhebungen 7a und Vertiefungen 7b auf, die der Einfachheit halber in dem Horizontalquerschnitt weggelassen wurden. An der entgegengesetzten linken Stirnseite 4a sind entsprechende, zu den Erhebungen und Vertiefungen 7a, 7b korrespondierende Erhebungen und Vertiefungen 8a, 8b in der Weise angeordnet, dass dort, wo bei der linken Stirnseite 4a Erhebungen vorhanden sind bei der rechten Stirnseite 4b Vertiefungen auftreten und umgekehrt.Finally, the right end face 4b of the insulating element 1 has on its outer side a series of elevations 7a and depressions 7b, which have been omitted in the horizontal cross section for the sake of simplicity. Corresponding elevations and depressions 8a, 8b corresponding to the elevations and depressions 7a, 7b are arranged in the opposite left-hand end face 4a in such a way that depressions occur at the right-hand end face 4b where, in the case of the left end face 4a, elevations occur and vice versa ,

Wenn dann mehrere mauersteinförmige Wärmedämmelemente in Längsrichtung nebeneinander angeordnet werden, so dass die jeweiligen Stirnseiten aneinander angrenzen, können die versetzt angeordneten Erhebungen 7a, 7b, 8a, 8b der jeweilig aneinander angrenzenden Stirnseiten 4a, 4b der verschiedenen Wärmedämmelemente ineinandergreifen und so beispielsweise mit Hilfe einer entsprechenden Verklebung einen optimalen Verbund ermöglichen.If then several brick-shaped thermal insulation elements are arranged side by side in the longitudinal direction, so that the respective end faces adjacent to each other, the staggered elevations 7a, 7b, 8a, 8b of the respective adjacent end faces 4a, 4b of the various thermal insulation elements interlock and so for example with the aid of a corresponding Bonding allow an optimal bond.

Figur 4 zeigt zwei weitere erfindungsgemäße mauersteinförmige Wärmedämmelemente 11, 12 in Einbausituationen.FIG. 4 shows two further brick-shaped thermal insulation elements 11, 12 according to the invention in installation situations.

Dabei ist das Wärmedämmelement 11 zwischen einer Gebäudeaußenwand 13 und einer Gebäudekellerdecke 14 aus Beton angeordnet. Durch die besonderen Dämmeigenschaften des Wärmedämmelements 11 wird der Wärmefluss von der Gebäudeaußenwand 13 in die Kellerdecke 14 durchbrochen.In this case, the thermal insulation element 11 is disposed between a building exterior wall 13 and a building basement ceiling 14 made of concrete. Due to the special insulating properties of the thermal insulation element 11, the heat flow from the building exterior wall 13 into the basement ceiling 14 is broken.

Deutlich zu erkennen ist der innere Aufbau des Wärmedämmelementes 11, das im Wesentlichen so aufgebaut ist wie das Wärmedämmelement 2 der Figur 3:Clearly visible is the internal structure of the thermal insulation element 11, which is constructed substantially the same as the thermal insulation element 2 of Figure 3:

Äußere Längsseiten 15a, 15b eines Isolierelementes 16 fassen zusammen mit einer Zwischenwand 17 zwei Tragelemente 18a, 18b ein.Outer longitudinal sides 15a, 15b of an insulating element 16, together with an intermediate wall 17, hold two support elements 18a, 18b.

Im Unterschied zu dem mauersteinförmigen Wärmedämmelement 2 der Figur 3 ist allerdings hier die Zwischenwand 17 nicht nur doppelt so dick wie die Außenwände sondern mehr als vierfach so dick, um einen noch weiter außen liegenden Tragelemente-Flächenschwerpunkt zu erhalten.In contrast to the brick-shaped thermal insulation element 2 of Figure 3, however, here the intermediate wall 17 is not only twice as thick as the outer walls but more than four times as thick, to obtain an even more outlying support elements centroid.

Obwohl hier nicht dargestellt, weisen die Tragflächen der Tragelemente 18a, 18b Profilierungen auf, durch die ein besonders fester, Horizontalkräfte optimal aufnehmender Verbund des mauersteinförmigen Wärmedämmelementes mit der Gebäudeaußenwand 13 einerseits und der Gebäudekellerdecke 14 andererseits erzielt wird, da sich als Verbindungsmaterial eingesetzter Mörtel mit diesen Profilierungen formschlüssig verbindet.Although not shown here, the support surfaces of the support elements 18a, 18b profiles, through which a particularly strong, horizontal forces optimally receiving composite of the brick-shaped thermal insulation element with the building exterior wall 13 on the one hand and the building basement ceiling 14 on the other hand is achieved because of used as a bonding material mortar with these Form-fitting profiles.

Das zweite mauersteinförmige Wärmedämmelement 12 der Figur 4 entkoppelt den Wärmefluss zwischen der Kellerdecke 12 und einer im Inneren des Gebäudes angeordneten Gebäudeinnenwand 19. Dabei ist zu erkennen, dass das Wärmedämmelement 12, aufgrund dessen Anpassung an die Wandstärke der Innenwand 19, schmaler ist als das Wärmedämmelement 11.The second brick-shaped thermal insulation element 12 of Figure 4 decouples the heat flow between the basement ceiling 12 and a arranged inside the building building inner wall 19. It can be seen that the thermal insulation element 12, due to its adaptation to the wall thickness of the inner wall 19, is narrower than the thermal insulation element 11th

Ansonsten ist auch dieses Wärmedämmelement 10 aus zwei äußeren Längsseiten 21 a, 21 b eines Isolierelementes 20 aufgebaut, das durch eine mittig verlaufende Zwischenwand 22 geteilt wird. Auch das Isolierelement 20 besteht aus Polystyrol. Zwei Tragelemente 23a und 23b werden von den Längsseiten 21 a, 21 b des Isolierelementes 20 eingefasst.Otherwise, this thermal insulation element 10 is composed of two outer longitudinal sides 21 a, 21 b of an insulating element 20, which is divided by a centrally extending intermediate wall 22. Also, the insulating member 20 is made of polystyrene. Two support members 23 a and 23 b are bordered by the longitudinal sides 21 a, 21 b of the insulating element 20.

Weiter sind in der Figur 4 zwei auf die Kellerdecke 12 aufgebrachte, übereinander angeordnete Fußbodenisolierungen 24a, 24b zur Wärmeentkopplung zwischen Keller und Erdgeschoss zu sehen, auf denen ein Estrich 30 verlegt ist.Further, in Figure 4, two applied to the basement ceiling 12, stacked floor insulation 24a, 24b for heat insulation between basement and ground floor to see on which a screed 30 is laid.

Eine Kelleraußenwand 25 ist zu erkennen, an die Erdreich 26 angrenzt. Die Gebäudeinnenwand 19 weist im Übrigen an ihrer linken und rechten Außenseite jeweils einen Putz 27a, 27b auf, die Gebäudeaußenwand 13 einen entsprechenden auf der Innenseite angeordneten Putz 28.A basement outer wall 25 can be seen, adjacent to the soil 26. The building inner wall 19 has, moreover, on each of its left and right outer sides a plaster 27a, 27b, the outer wall 13 of the building has a corresponding plaster 28 arranged on the inner side.

Schließlich ist noch eine Außendämmung 29 dargestellt, die an der Außenseite der Gebäudeaußenwand 13 und der Kellerdecke 14 anliegt und sich bis in das Erdreich erstreckt.Finally, an external insulation 29 is shown, which rests against the outside of the building exterior wall 13 and the basement ceiling 14 and extends into the ground.

Die vorliegende Erfindung stellt insgesamt ein mauersteinförmiges Wärmedämmelement zur Wärmentkopplung zwischen Wandteilen und Boden- oder Deckenteilen zur Verfügung, das sich insbesondere durch eine hohe Druckfestigkeit auszeichnet sowie einen großen Widerstand gegenüber horizontalen Schubkräften. Eine Optimierung der Tragelement- und Isolierelementmaterialien und -querschnitte ermöglicht bei gegebenen Anforderungen an die Festigkeit des Wärmedämmelements eine besonders hohe Wärmedämmung.The present invention provides a total of a brick-shaped thermal insulation element for heat coupling between wall parts and floor or ceiling parts available, which is characterized in particular by a high compressive strength and a large resistance to horizontal shear forces. An optimization of Tragelement- and Isolierelementmaterialien and cross-sections allows for given requirements for the strength of the thermal insulation element a particularly high thermal insulation.
