Description

  

  
 



   In neuerer Zeit werden beim Bau von Häusern häufig vorfabrizierte Wände verwendet. Diese müssen primär eine ausreichende Festigkeit aufweisen, um die vorgesehenen Belastungen aufnehmen zu können. Des weitern sollen sie eine möglichst gute Wärmeisolierung ergeben.



   Ein bekanntes Bauelement für die Herstellung von Wänden besteht aus zwei Blechschalen gleicher Grösse mit abgewinkelten Rändern. Der von den beiden Schalen begrenzte Hohlraum wird nach aussen durch mit den Rändern verbundene Dichtungsstreifen dicht abgeschlossen. Im Hohlraum ist eine mit den Schalen verbundene Isolierplatte angeordnet. Dieses Bauelement ergibt jedoch nur eine relativ geringe Wärmedämmung. Zudem entstehen bei diesem Bauelement, wenn   nvi-    schen den beiden Schalen Temperaturunterschiede bestehen, grosse Spannungen.



   Ein weiteres bekanntes Bauelement weist einen durch zwei Schalen begrenzten, gegen aussen mehr oder weniger dicht abgeschlossenen Hohlraum auf, in dem reflektierende Metallfolien angeordnet sind. Dieses Bauelement ergibt zwar anfänglich eine recht hohe Wärmedämmung. Bei Abkühlungen schlägt sich bei diesem Bauelement jedoch auf den Folien Feuchtigkeit nieder. Dies hat zur Folge, dass das Bauelement allmählich durchfeuchtet wird und dass das Reflexionsvermögen der Folien abnimmt. Dadurch wird die Wärmedämmung stark herabgesetzt. Zudem ergibt dieses vorbekannte Bauelement nur eine ungenügende Schallisolation.



   Es ist nun bereits ein Bauelement mit einem evakuierten Hohlraum bekannt. Dieses Bauelement weist eine recht grosse Wärme- und Schalldämmung auf. Bei diesem Bauelement wird jedoch der evakuierte Hohlraum unmittelbar durch die tragenden Aussenschalen begrenzt. Dies hat den Nachteil,dass bereit geringfügige Beschädigungen der Aussenschalen, etwa das Befestigen einer Schraube, zu einem Verlust des Vakuums führen können.



   Der Erfindung liegt nun die Aufgabe zugrunde, ein Bauelement zu schaffen, das die genannten Nachteile nicht aufweist.



   Diese Aufgabe wird gelöst durch ein Bauelement mit mindestens einem gegen aussen dicht abgeschlossenen, mindestens einen Reflektor enthaltenden oder durch Reflektoren begrenzten Hohlraum, wobei der Hohlraum einen Unterdruck aufweist, oder wobei mindestens ein Anschluss zum Anschliessen einer zur Erzeugung eines Unterdruckes dienenden Saugpumpe vorhanden ist. Das Bauelement ist gemäss der Erfindung gekennzeichnet durch   nvei    Schalen, zwischen denen ein die Wandung des Hohlraumes bildendes Isolierelement angeordnet ist.



   Die Erfindung soll nun anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. In der Zeichnung zeigen die Fig. 1 einen Schnitt durch ein Bauelement mit einem eingesetzten Isolierelement und die Fig. 2 eine axonometrische Ansicht eines aufgebrochenen Isolierelementes.



   Die Figur 1 zeigt ein Bauelement zur Bildung einer Aussenwand oder eines Teils einer Aussenwand für ein Haus. Das Bauelement weist beidseitig eine etwa durch eine Metallplatte gebildete Schale 1 auf. Die Aussenseiten der beiden Schalen 1 sind mit einem Überzug 2 versehen, der zur Verhinderung der Korrosion dient und etwa durch eine Kunststoffschicht oder -folie gebildet werden kann. Die Innen-Seiten, das heisst, die einander zugewandten Seiten der beiden Schalen 1 sind je mit einer Reflektor-Folie 3 versehen. Diese weist mindestens auf ihrer dem Innern des Bauelementes zugewandten Seite eine glänzende, insbesondere im Infrarot-Bereich hochreflektierende Oberfläche auf.



   Die Reflektor-Folie kann etwa aus Aluminium, einem anderen Metall oder einer metallisierten Kunststoff-Folie bestehen.



  Am oberen und unteren Ende des Bauelementes sind Vierkant-Kunststoffrohre 4 mit einer darin eingebetteten Leiste 5 angeordnet. Die beiden Schalen 1 sind durch nicht dargestellte Verschraubungsmittel mit den Vierkantrohren 4 und den Leisten 5 oder direkt miteinander verbunden. Zwischen den beiden Vierkantrohren 4 sind auf den Innenseiten der beiden Schalen 1, oder genauer gesagt, auf den Reflektor-Folien 3 Wabenplatten 6 mit Öffnungen 6a befestigt. Die Wabenplatten 6 sind mit einem Isolierelement 7 verbunden. Dieses weist beidseitig eine zu den Schalen 1 parallele Aluminiumplatte 8 auf. Die beiden Platten 8 sind mindestens auf der Innenseite poliert, so dass ihre Oberflächen eine grosse Reflexion aufweisen. Der von den beiden Aluminiumplatten 8 begrenzte Zwischenraum wird oben und unten durch Abschlusselemente, nämlich durch die Dichtungs-Folien 9 und die Rohre 4, dicht abgeschlossen.



   Im Isolierelement 7 kann zusätzlich der in der Figur 2 dargestellte Rahmen 11 angeordnet sein. Der Rahmen 11 weist eine Bodenplatte   1 1a    und eine Deckplatte   1 1b    auf, die beidseitig durch Profilstäbe 11c miteinander fest verbunden sind.



  Die Profilstäbe sind durch Streben   1 1d    miteinander verstrebt.



  An der Deckplatte   1 1b    sind mehrere zueinander parallele Schienen 12 befestigt. Diese sind mit miteinander fluchtenden Bohrungen 12a versehen. An den Schienen 12 sind mittels in den Bohrungen 12a sitzender Gewindebolzen 14 Reflektor Folien 13 befestigt, die bei den oberen und unteren Rändern mit Bohrungen 15a aufweisenden Verstärkungsstreifen 15 versehen sind. In den Bohrungen 15a des unteren Verstärkungsstreifens 15 sind Zugfedern 16 eingehängt, deren anderes Ende mit der Bodenplatte   1 1a    verbunden ist. Die an den Reflektor-Folien 13 angreifenden Zugfedern 16 werden in die Folien gespannt, so dass sie parallel zueinander verlaufen und einander nirgends berühren.



   Das Isolierelement 7 wird beim Zusammenbau durch einen nicht dargestellten Anschluss ganz oder teilweise evakuiert.



  Die Rohre 4 werden dann durch den Luftdruck zusätzlich gegen die Dichtungs-Folien 9 und die Platten 8 gedrückt.



  Selbstverständlich ist es auch möglich, anstelle der Folien 9 massive Platten an den Aluminiumplatten 8 zu befestigen, so dass das Isolierelement 7 ein dichtes Gehäuse bildet, das eine zum Aufnehmen der beim Evakuieren auftretenden Kräfte ausreichende Stabilität aufweist. Dies hat den Vorteil, dass der Zusammenbau des Bauelementes wesentlich erleichtert wird.



   Des weitern ist es möglich, den Anschluss nach aussen zu führen oder zumindest von aussen zugänglich zu machen und das Bauelement erst bei der Verwendung zu evakuieren. Ein nach aussen geführter Anschluss hat den Vorteil, dass das Isolierelement bei Bedarf nachevakuiert werden kann.



   Durch die Evakuierung der Hohlräume kann die Wärmeleitung in den Bauelementen senkrecht zu den Wänden sehr stark reduziert werden. Da die Innenwände der Hohlräume durch Reflektoren gebildet werden, wird auch der Wärmetransport durch Strahlung auf ein Minimum reduziert. Die Wärmeübertragung durch die Strahlung wird durch die im Innern der Hohlräume angeordneten, zusätzlichen Reflektoren noch weiter reduziert. Durch die Evakuierung wird gewährleistet, dass sich auf den Reflektoren keine Feuchtigkeit niederschlägt, so dass die Reflektoren ihr grosses Reflexionsvermögen über unbegrenzte Zeit beibehalten.

 

   Da Schall nur über Stoffe übertragen werden kann, ergibt die Evakuierung selbstverständlich auch eine grosse Schalldämmung.

 

   Das Bauelement kann selbstverständlich in mancher Weise modifiziert werden. Beispielsweise ist es möglich, auf derjenigen Seite, die die Innenseite des Gebäudes bildet, einen weiteren Hohlraum vorzusehen, der etwa die Form eines schlangenförmig verlaufenden Durchgangs aufweist und ein Heiz- oder   Kühlmittel aufnehmen kann. Dieser Hohlraum kann dann über Zu- und Ableitungsanschlüsse mit einer Förderpumpe und einer Heiz- oder Kühlvorrichtung verbunden sein. Eine solche Ausbildung der Bauelemente ermöglicht,,das Gebäude   iI    vorteilhafter Weise zu heizen oder zu kühlen, das heisst zu klimatisieren.



   Des weiteren kann jedes Bauelement mit mehreren, durch je ein Isolierelement gebildeten, über je einen Anschluss evakuierbaren Hohlräumen versehen sein. Dies hat den Vorteil, dass im Falle eines Lecks das Vakuum nicht im ganzen Bauelement zusammenbricht. 



  
 



   In recent times, prefabricated walls are often used in the construction of houses. These must primarily have sufficient strength to be able to absorb the intended loads. Furthermore, they should provide the best possible thermal insulation.



   A well-known component for the production of walls consists of two metal shells of the same size with angled edges. The cavity bounded by the two shells is sealed off from the outside by sealing strips connected to the edges. An insulating plate connected to the shells is arranged in the cavity. However, this component results in only a relatively low level of thermal insulation. In addition, if there are temperature differences between the two shells, great stresses arise in this component.



   Another known component has a cavity delimited by two shells, closed more or less tightly from the outside, in which reflective metal foils are arranged. This component initially provides a very high level of thermal insulation. When this component cools down, however, moisture is deposited on the foils. This has the consequence that the component is gradually soaked through and that the reflectivity of the foils decreases. This greatly reduces the thermal insulation. In addition, this known component only results in insufficient sound insulation.



   A component with an evacuated cavity is already known. This component has a very high level of heat and sound insulation. In this component, however, the evacuated cavity is bounded directly by the supporting outer shells. This has the disadvantage that even slight damage to the outer shells, such as the fastening of a screw, can lead to a loss of the vacuum.



   The invention is now based on the object of creating a component that does not have the disadvantages mentioned.



   This object is achieved by a component with at least one cavity sealed from the outside, containing at least one reflector or delimited by reflectors, the cavity having a negative pressure or at least one connection for connecting a suction pump used to generate a negative pressure. According to the invention, the component is characterized by nvei shells, between which an insulating element forming the wall of the cavity is arranged.



   The invention will now be explained in more detail using an exemplary embodiment shown in the drawing. In the drawing, FIG. 1 shows a section through a component with an inserted insulating element and FIG. 2 shows an axonometric view of a broken-open insulating element.



   FIG. 1 shows a component for forming an outer wall or part of an outer wall for a house. The component has a shell 1 formed approximately by a metal plate on both sides. The outside of the two shells 1 are provided with a coating 2, which serves to prevent corrosion and can be formed, for example, by a plastic layer or film. The inner sides, that is to say the sides of the two shells 1 facing one another, are each provided with a reflector film 3. This has at least on its side facing the interior of the component a shiny surface, in particular highly reflective in the infrared range.



   The reflector foil can consist of aluminum, another metal or a metallized plastic foil.



  At the top and bottom of the component, square plastic pipes 4 with a bar 5 embedded therein are arranged. The two shells 1 are connected to the square tubes 4 and the strips 5 or directly to one another by screwing means (not shown). Between the two square tubes 4, honeycomb panels 6 with openings 6a are fastened on the insides of the two shells 1, or more precisely on the reflector foils 3. The honeycomb panels 6 are connected to an insulating element 7. This has an aluminum plate 8 parallel to the shells 1 on both sides. The two plates 8 are polished at least on the inside so that their surfaces have a high degree of reflection. The space delimited by the two aluminum plates 8 is tightly closed at the top and bottom by closing elements, namely by the sealing foils 9 and the tubes 4.



   The frame 11 shown in FIG. 2 can also be arranged in the insulating element 7. The frame 11 has a base plate 11a and a cover plate 11b, which are firmly connected to one another on both sides by profile rods 11c.



  The profile bars are braced together by struts 1 1d.



  A plurality of rails 12 parallel to one another are attached to the cover plate 11b. These are provided with aligned holes 12a. Reflector foils 13 are attached to the rails 12 by means of threaded bolts 14 seated in the bores 12a and are provided with reinforcing strips 15 having bores 15a at the upper and lower edges. In the bores 15a of the lower reinforcing strip 15 tension springs 16 are suspended, the other end of which is connected to the base plate 11a. The tension springs 16 acting on the reflector foils 13 are tensioned in the foils so that they run parallel to one another and do not touch one another anywhere.



   The insulating element 7 is completely or partially evacuated during assembly through a connection (not shown).



  The tubes 4 are then additionally pressed against the sealing foils 9 and the plates 8 by the air pressure.



  Of course, it is also possible to attach solid plates to the aluminum plates 8 instead of the foils 9, so that the insulating element 7 forms a tight housing which has sufficient stability to absorb the forces occurring during evacuation. This has the advantage that the assembly of the component is made much easier.



   Furthermore, it is possible to lead the connection to the outside or at least to make it accessible from the outside and to evacuate the component only when it is used. An outward connection has the advantage that the insulating element can be evacuated again if necessary.



   By evacuating the cavities, the conduction of heat in the components perpendicular to the walls can be reduced very significantly. Since the inner walls of the cavities are formed by reflectors, the heat transport through radiation is also reduced to a minimum. The heat transfer through the radiation is further reduced by the additional reflectors arranged in the interior of the cavities. The evacuation ensures that no moisture is deposited on the reflectors, so that the reflectors retain their high reflectivity for an unlimited period of time.

 

   Since sound can only be transmitted through materials, evacuation naturally also provides great sound insulation.

 

   The component can of course be modified in some ways. For example, it is possible to provide a further cavity on the side that forms the inside of the building, which has the shape of a serpentine passage and can accommodate a heating or cooling agent. This cavity can then be connected to a feed pump and a heating or cooling device via inlet and outlet connections. Such a design of the components makes it possible to advantageously heat or cool the building, that is to say to air-condition it.



   Furthermore, each component can be provided with a plurality of cavities, each formed by an insulating element, which can be evacuated via a respective connection. This has the advantage that in the event of a leak, the vacuum does not break down in the entire component.
