Description

Die Erfindung betrifft ein Wandbauelement mit Hohlkammern und mit einer Wärmedämmbeschichtung zur Erhöhung der Wärmeübergangswiderstände in den Hohlkammern.The invention relates to a wall component with hollow chambers and with a thermal insulation coating to increase the heat transfer resistance in the hollow chambers.

Es ist seit langem bekannt, Wandbauelemente, z.B. sogenannte Hohlblocksteine oder auch Platten mit Hohlkammern zu versehen, um bei der Herstellung der Steine Material einzusparen. Der mit der Ausbildung der Hohlkammern einhergehende Masseverlust eines solchen Steines beeinträchtigt aber die Wärmedämmeigenschaft.It has long been known to use wall components, e.g. to provide so-called hollow blocks or plates with hollow chambers in order to save material in the manufacture of the stones. The loss of mass associated with the formation of the hollow chambers of such a stone, however, affects the thermal insulation property.

Um trotzdem eine gute Wärmedämmung zu erreichen, ist es bekannt, in den Hohlkammern ein Material anzuordnen, welches eine schlechte Wärmeleitfähigkeit hat, um damit die Wärmedämmeigenschaften zu erhöhen. Beispielsweise wurde vorgeschlagen, die Hohlkammern mit Schaumstoff, z.B. Polystyrol auszufüllen (DE-OS 29 14 647).In order to nevertheless achieve good thermal insulation, it is known to arrange a material in the hollow chambers which has poor thermal conductivity in order to increase the thermal insulation properties. For example, it has been proposed to fill the hollow chambers with foam, e.g. Fill in polystyrene (DE-OS 29 14 647).

Darüberhinaus ist aus der AT-PS 175 689 bekannt, die Hohlkammern eines Hohlblocksteines mit einer Folie auszukleiden, um damit die Hohlkammern luftdicht auszubilden. Auf diese Weise soll ein Luftein- bzw. Austritt durch ein solches Wandbauelement verhindert werden.In addition, it is known from AT-PS 175 689 to line the hollow chambers of a hollow block with a film in order to make the hollow chambers airtight. In this way, an air inlet or outlet should be prevented by such a wall component.

Diese Maßnahmen bewirken bereits eine Verringerung der Wärmeverluste eines solchen Wandbauelementes. Die Anbringung der Folie in den Hohlkammern eines Wandbauelementes ist jedoch sehr aufwendig und hat sich daher in der Praxis kaum durchgesetzt.These measures already reduce the heat losses of such a wall component. However, the application of the film in the hollow chambers of a wall component is very complex and has therefore hardly become established in practice.

Aufgrund der allgemeinen Bestrebungen, im Zusammenhang mit Rohstoff- und Energieeinsparung auch Gebäude mit guten Wärmedämmeigenschaften bauen zu können, ist es auch wünschenswert, die Wärmedämmeigenschaften solcher Wandbauelemente noch weiter zu erhöhen.Due to the general efforts to be able to build buildings with good thermal insulation properties in connection with saving raw materials and energy, it is also desirable to further increase the thermal insulation properties of such wall components.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Wandbauelement der eingangs genannten Art zu schaffen, welches konstruktiv einfach ausgebildet ist und eine noch bessere Wärmedämmeigenschaft als die bekannten derartigen Bauelemente hat.The invention is therefore based on the object of providing a wall component of the type mentioned at the outset which is structurally simple and has an even better thermal insulation property than the known components of this type.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in die Hohlkammern aus einzelnen Hohlkammerelementen zusammengesetzte Hohlkammereinschübe eingeschoben sind, wobei jedes Hohlkammereli-%' ment aus einer Platte und von dieser abstehenden Stegen gebildet wird, die die Platten in einem Abstand zueinander halten, und daß die Wärmedämmbeschichtung auf den Plattenflächen angebracht ist.This object is achieved in that hollow chamber inserts composed of individual hollow chamber elements are inserted into the hollow chambers, each hollow chamber element being formed from a plate and webs projecting therefrom which keep the plates at a distance from one another, and in that the thermal insulation coating is attached to the plate surfaces.

Die Erhöhung der Wärmeübergangswiderstände innerhalb der Hohlkammern mit einer Wärmedämmbeschichtung bewirkt, daß außer den Verlusten, wie sie durch einen Leitungswärmeausgleich mit der Umgebung stattfinden, auch die Strahlungsverluste der erfindungsgemäßen Wandbauelemente stark reduziert werden können. Ein erfindungsgemäßes Wandbauelement hat daher verbesserte Wärmedämmeigenschaften, weil nicht nur Leitungs-, sondern auch Strahlungsverluste vermindert werden. Dabei ist die Konstruktion dieser Wandelemente denkbar einfach, da die Hohlkammer Einschübe einfach in die Hohlkammern des Wandbauelementes einzuschieben sind, ohne daß sie mit einem Bindemittel an die Innenwände der Hohlkammern aufgeklebt werden müssen. Die auf den Platten der Hohlkammerelemente aufgebrachte Wärmedämmbeschichtung bewirkt, daß die Strahlung zwar aus den Innenwänden der Hohlkammern austreten kann, jedoch innerhalb der Hohlkammern an den Hohlkammereinschüben stark geschwächt wird, so daß es nicht bzw. nur stark vermindert zu Abstrahlungen nach außen kommt. Die mit Stegen voneinander auf Abstand gehaltenen Platten unterteilen die Hohlkammern in dünne Luftschichten zwischen den einzelnen Plattenlagen, was an sich schon zu einer Strahlungsreduzierung führt. Da die Platten zusätzlich noch mit einer Wärmedämmbeschichtung versehen sind, wird durch den ständigen Wechsel zwischen dünner Luft und Wärmedämmbeschichtung eine sehr starke und wirkungsvolle Reduzierung der Strahlung innerhalb der Hohlkammern erreicht. Da die Hohlkammereinschübe aus einzelnen Hohlkammerelementen zusammengesetzt sind, besteht die einfache Möglichkeit, jede einzelne Platte mit der Wärmdämmbeschichtung zu versehen und die einzelnen Elemente schichtweise aufeinanderzulegen. Dadurch können unterschiedlich große Hohlräume ausgeführt werden, weil die einzelnen Elemente entsprechend der Abmessungen der Hohlkammern aufeinanderlegbar bzw. kombinierbar sind.The increase in the heat transfer resistances within the hollow chambers with a thermal insulation coating has the effect that, in addition to the losses that occur due to a line heat compensation with the environment, the radiation losses of the wall components according to the invention can be greatly reduced. A wall component according to the invention therefore has improved thermal insulation properties because not only conduction losses but also radiation losses are reduced. The construction of these wall elements is very simple, since the hollow chamber inserts can simply be inserted into the hollow chambers of the wall component without having to be glued to the inner walls of the hollow chambers with a binder. The thermal insulation coating applied to the plates of the hollow chamber elements has the effect that the radiation can emerge from the inner walls of the hollow chambers, but is greatly weakened within the hollow chambers at the hollow chamber inserts, so that there is no or only greatly reduced radiation to the outside. The plates, which are spaced apart by webs, divide the hollow chambers into thin layers of air between the individual plate layers, which in itself leads to a reduction in radiation. Since the plates are also provided with a thermal insulation coating, the constant change between thin air and thermal insulation coating makes them very strong and effective reduction of radiation within the hollow chambers achieved. Since the hollow chamber inserts are composed of individual hollow chamber elements, there is the simple possibility of providing each individual plate with the thermal insulation coating and placing the individual elements on one another in layers. As a result, cavities of different sizes can be designed because the individual elements can be placed on one another or combined in accordance with the dimensions of the hollow chambers.

Die Hohlkammerelemente können in einfacher Weise aus Pappdeckel aufgebaut sein, können aber auch Kunststoffteile sein. Derartige Materialien haben bekannterweise schlechte Wärmeleitzahlen, so daß damit sowohl die Wärmeleitung als auch die Wärmestrahlung innerhalb der Hohlkammern reduziert werden kann.The hollow chamber elements can be constructed in a simple manner from cardboard lids, but can also be plastic parts. Such materials are known to have poor thermal coefficients, so that both the heat conduction and the heat radiation within the hollow chambers can be reduced.

In einer Weiterbildung der Erfindung umfaßt die Wärmedämmbeschichtung metallische Stoffe. Z.B. könnten in der angegebenen Art und Weise dünne Metallfolien verwendet werden, um die Abstrahlung zu reduzieren. Es ist jedoch wesentlich einfacher, wenn die Wärmedämmbeschichtung aus einem Trägerstoff aus Kunststoff und beigemischten Metallpartikeln besteht. Die Metallpartikel können vorzugsweise Aluminiumpulver sein. Eine solche Wärmedämmbeschichtung läßt sich einfacher entweder auf die Innenwände der Hohlkammern oder aber auf die Hohlkammerelemente selbst auftragen. Natürlich ist es auch möglich, sowohl die Hohlkammerelemente als auch die Hohlkammerinnenflächen mit der Wärmedämmbeschichtung zu versehen.In a development of the invention, the thermal insulation coating comprises metallic substances. E.g. thin metal foils could be used in the specified manner in order to reduce the radiation. However, it is much easier if the thermal insulation coating consists of a carrier material made of plastic and admixed metal particles. The metal particles can preferably be aluminum powder. Such a thermal insulation coating is easier to apply either to the inner walls of the hollow chambers or to the hollow chamber elements themselves. Of course, it is also possible to provide both the hollow chamber elements and the hollow chamber inner surfaces with the thermal insulation coating.

Dabei ist es günstig, wenn die Wärmedämmbeschichtung sprühfähig ist, so daß die Wärmedämmbeschichtung auf die Innenwände der Hohlkammern aufgesprüht werden kann und sich dann verfestigt.It is advantageous if the thermal insulation coating is sprayable, so that the thermal insulation coating can be sprayed onto the inner walls of the hollow chambers and then solidifies.

Das Aufbringen der Wärmedämmbeschichtung auf den Hohlkammerelementen ist dann auch sehr einfach. Diese werden ebenfalls mit der Wärmedämmbeschichtung besprüht und nach der Verfestigung der Wärmedämmbeschichtung dann in die Hohlkammern eingesetzt.The application of the thermal insulation coating on the hollow chamber elements is then also very simple. These are also sprayed with the thermal insulation coating and then inserted into the hollow chambers after the thermal insulation coating has solidified.

Die Erfindung wird im folgenden anhand von zwei in den Zeichnungen dargestellten Ausführungsbeispielen weiter erläutert und beschrieben.

  • Figur 1 zeigt einen Ausschnitt eines erfindungsgemäßen Wandbauelementes in perspektivischer, teilweise geschnittener Darstellung.
  • Figur 1A zeigt ein Hohlkammerelement nach der Erfindung.
  • Figur 2 zeigt in einem weiteren Ausführungsbeispiel ein erfindungsgemäßes Wandbauelement in perspektivischer, geschnittener Teilansicht mit einem Hohlkammereinschub in perspektivischer Explosionsdarstellung.
The invention is further explained and described below with reference to two exemplary embodiments shown in the drawings.
  • Figure 1 shows a detail of a wall component according to the invention in a perspective, partially sectioned representation.
  • Figure 1A shows a hollow chamber element according to the invention.
  • FIG. 2 shows a further exemplary embodiment of a wall component according to the invention in a perspective, sectional partial view with a hollow chamber insert in a perspective exploded view.

In Figur 1 ist ein Teil eines Hohlblocksteins 1 in perspektivischer Darstellung gezeigt. Dieser Hohlblockstein 1 besteht aus einem massiven Körper, durch den sich mehrere Hohlkammern 2 erstrecken.In Figure 1, a part of a hollow block 1 is shown in perspective. This hollow block 1 consists of a solid body through which several hollow chambers 2 extend.

In den Hohlkammern sind Hohlkammereinschübe 4 angeordnet, die die Wärmedämmeigenschaften des Hohlblocksteines vergrößern, indem sie Wärmeverluste über die Hohlkammern reduzieren.Hollow-chamber inserts 4 are arranged in the hollow chambers, which increase the thermal insulation properties of the hollow block by reducing heat losses through the hollow chambers.

Bei dem in Figur 1 dargestellten Hohlblockstein 1 sind in einigen Kammern die Hohlkammereinschübe 4 schematisch dargestellt.In the hollow block 1 shown in FIG. 1, the hollow chamber inserts 4 are shown schematically in some chambers.

In Figur 1A ist ein Hohlkammerelement 3 teilweise und perspektivisch dargestellt. Jeder Hohlkammereinschub 4 besteht aus mehreren solchen Hohlkammerelementen 3.A hollow chamber element 3 is shown partially and in perspective in FIG. 1A. Each hollow chamber insert 4 consists of several such hollow chamber elements 3.

Die dargestellten Hohlkammerelemente 3 sind aus Pappe oder Kunststoff hergestellt und weisen eine flache Platte 5 auf, von der weg sich nach oben und unten senkrecht abstehende Stege 6 erstrecken. Je nach Durchmesser und Ausmaßen der Hohlkammern können mehrere solcher Hohlkammerelemente 3 übereinandergelegt werden, so daß sie insgesamt einen Hohlkammereinschub 4 bilden, der in der Dicke und den Abmessungen denjenigen der Hohlkammern entspricht.The hollow chamber elements 3 shown are made of cardboard or plastic and have a flat plate 5 from which webs 6 projecting vertically upwards and downwards. Depending on the diameter and dimensions of the hollow chambers, several such hollow chamber elements 3 can be placed one on top of the other, so that they form a hollow chamber insert 4 overall, which corresponds to the thickness and dimensions of those of the hollow chambers.

In dem in der Figur 1 und 1A dargestellten Ausführungsbeispiel sind die Hohlkammerelemente 3 beidseitig der Platte 5 mit einer Wärmedämmbeschichtung 7 versehen. Diese Wärmedämmbeschichtung hat die Eigenschaft, Wärmeübergangswiderstände zu vergrößern. Die Wärmedämmbeschichtung besteht zu diesem Zweck aus einem Trägerstoff aus Kunststoff mit einem Aluminiumpulver und wurde auf jedes einzelne Hohlkammerelement 3 auf beiden Seiten der Platte 5 aufgesprüht.In the embodiment shown in FIGS. 1 and 1A, the hollow chamber elements 3 are provided on both sides of the plate 5 with a thermal insulation coating 7. This thermal insulation coating has the property of increasing heat transfer resistance. For this purpose, the thermal insulation coating consists of a carrier material made of plastic with an aluminum powder and was sprayed onto each individual hollow chamber element 3 on both sides of the plate 5.

In diesem Ausführungsbeispiel sind die Innenwände der Hohlkammern selbst nicht mit einer Wärmedämmschicht überzogen.In this embodiment, the inner walls of the hollow chambers themselves are not covered with a thermal barrier coating.

Die zu einem Hohlkammereinschub 4 zusammengesetzten Hohlkammerelemente 3 bewirkten, daß zunächst die Luft innerhalb der Hohlkammern 2 in dünne (der Höhe der Stege 6 entsprechende) Luftschichten unterteilt wird. Darüber hinaus entsteht insgesamt in der Hohlkammer eine abwechselnde Schichtung aus Luft, der Wärmedämmschicht 7, der Platte, einer nochmaligen Wärmedämmschicht usw. so daß durch diesen ständigen Wechsel die Wärmeabstrahlung aus den Hohlkammern stark reduziert wird.The hollow chamber elements 3 assembled into a hollow chamber insert 4 initially caused the air inside the hollow chambers 2 to become thin (corresponding to the height of the webs 6) air layers is divided. In addition, an alternating stratification of air, the heat insulation layer 7, the plate, a renewed heat insulation layer, etc. is created in the hollow chamber so that the heat radiation from the hollow chambers is greatly reduced by this constant change.

Bei dem in Figur 2 dargestellten Ausführungsbeispiel sind die Innenwände 8 der Hohlkammern 2 selbst mit einer Wärmedämmbeschichtung überzogen. Mehrere Hohlkammerelemente 3 sind, wie in der Explosionsdarstellung zu erkennen, mit ihren Stegen aufeinandergesetzt und in die Hohlkammern 2 eingeschoben. Die Wärmedämmbeschichtung sorgt in diesem Falle dafür, daß der Strahlungsaustritt aus den Innenwänden 8 stark vermindert wird. Die Unterteilung der Hohlkammern 2 in dünne Luftschichten mittels der aufeinandergesetzten Hohlkammerelemente reduziert die Strahlung weiterhin. Da die Hohlkammerelemente aus einem Material bestehen, welches eine schlechte Wärmeleitfähigkeit hat, wird außerdem die Wärmeleitung in den Hohlkammern stark reduziert.In the embodiment shown in Figure 2, the inner walls 8 of the hollow chambers 2 are themselves covered with a thermal barrier coating. As can be seen in the exploded view, a plurality of hollow chamber elements 3 are placed on top of one another with their webs and inserted into the hollow chambers 2. In this case, the thermal insulation coating ensures that the radiation exit from the inner walls 8 is greatly reduced. The subdivision of the hollow chambers 2 into thin air layers by means of the stacked hollow chamber elements further reduces the radiation. Since the hollow chamber elements are made of a material that has poor thermal conductivity, the heat conduction in the hollow chambers is also greatly reduced.

Es ist natürlich auch möglich, die beiden Ausführungsbeispiele zu kombinieren, d.h. sowohl die Innenwände 8 der Hohlkammern 7 als auch die einzelnen Platten 5 der Hohlkammerelemente 3 mit einer Wärmedämmbeschichtung zu überziehen, im allgemeinen wird dies jedoch nicht notwendig sein.It is of course also possible to combine the two exemplary embodiments, i.e. to coat both the inner walls 8 of the hollow chambers 7 and the individual plates 5 of the hollow chamber elements 3 with a thermal insulation coating, but in general this will not be necessary.

Die Wärmedämmbeschichtung kann, wie eingangs erwähnt, aufgesprüht werden, es ist jedoch auch möglich, sie in der Art einer Folie zu verwirklichen, so daß z.B. die Hohlkammerelemente mit einer solchen Folie überzogen werden könnten.The thermal insulation coating can, as mentioned at the beginning, be sprayed on, but it is also possible to implement it in the manner of a film, so that e.g. the hollow chamber elements could be covered with such a film.

Es ist natürlich auch möglich, andere als die dargestellten Hohlkammereinschübe zu verwenden. So ist es z.B. denkbar, die Innenwände 8 der Hohlblocksteine 1 mit der Wärmedämmbeschichtung mit den angegebenen Eigenschaften zu versehen und die Hohlkammern dann mit Polystyrol auszufüllen.It is of course also possible to use other hollow chamber inserts than those shown. So it is e.g. conceivable to provide the inner walls 8 of the hollow blocks 1 with the thermal insulation coating with the specified properties and then to fill the hollow chambers with polystyrene.

Auch bei anderen als Hohlblocksteinen, also z.B. bei plattenförmigen Wandbauelementen führt die Erfindung wirkungsvoll dazu, daß die Wärmedämmeigenschaften derartiger Elemente wesentlich verbessert werden.Also for other than hollow blocks, e.g. In the case of plate-shaped wall components, the invention effectively leads to the thermal insulation properties of such elements being significantly improved.

Vorteilhaft besteht die Wärmedämmbeschichtung 7 aus Buna-Kautschuk (Polybutadien-Kautschuk) gemischt mit Aluminiumpulver. Der Zusatz an Aluminiumpulver kann bis zu etwa 20 % betragen. Der Buna-Kautschuk wird mit Lösungsmittel und dem Aluminiumpulver so angemischt, daß sich eine Verarbeitungszeit von ca. 1 bis 2 Std. ergibt.The thermal insulation coating 7 advantageously consists of Buna rubber (polybutadiene rubber) mixed with aluminum powder. The addition of aluminum powder can be up to about 20%. The Buna rubber is mixed with solvent and the aluminum powder so that the processing time is approx. 1 to 2 hours.

Eine andere vorteilhafte Mischung für die Wärmedämmbeschichtung 7 besteht aus Siliconharzen und Aluminiumpulver. Dieser Mischung wird Härter in einer Menge zugesetzt, daß die Verarbeitungs- bzw. Abtropfzeit dem jeweiligen Beschichtungsverfahren (Auftragen von Hand oder Aufsprühen) gerecht wird.Another advantageous mixture for the thermal barrier coating 7 consists of silicone resins and aluminum powder. Hardener is added to this mixture in an amount such that the processing or draining time is appropriate for the respective coating process (manual application or spraying).

Wegen der bei der Lagerung der Steine möglichen Lichteinwirkung kann der Mischung ein Lichtschutzmittel zugegeben werden.Because of the possible exposure to light when storing the stones, a light stabilizer can be added to the mixture.

Die genannten Mischungen können einfach in einem Mischer oder einem Rührwerk gemischt werden.The mixtures mentioned can simply be mixed in a mixer or a stirrer.
