   Die Erfindung bezieht sich auf eine wärmeisolierende Bauplatte, insbesondere für Kühlhäuser, mit zwei eine
Kunststoffhartschaumschichte nach aussen feuchtigkeitsdicht abschliessenden Deckschichten. 



   Derartige wärmeisolierende Bauplatten, deren Deckschichten üblicherweise aus Stahlblech bestehen, haben sich vor allem als zusätzliche Wärmeisolation gut bewährt, wobei die einfache, kontinuierliche Herstellung als besonderer Vorteil gewertet wird. Werden jedoch besondere Anforderungen hinsichtlich der Wärmeisolation gestellt, wie sie beispielsweise bei Kühlhäusern auftreten, so muss die Stärke der Kunststoffhartschaumschichte einer solchen Bauplatte wesentlich erhöht werden. Bauplatten mit dicken Kunststoffhartschaumschichten zwischen den Deckschichten sind jedoch nicht mehr so einfach herzustellen, wie dies bei dünneren Bauplatten möglich ist.

   Zum Ausschäumen des Zwischenraumes zwischen den zwei Deckblechen ist nämlich eine vergleichsweise grosse Anlage erforderlich, da die zur Herstellung der Kunststoffhartschaumschichte benötigten
Schaumstoffkomponenten in einer entsprechenden Menge innerhalb kurzer Zeit zur Verfügung gestellt werden müssen. Ausserdem werden, um eine ausreichende statische Festigkeit der Bauplatten zu erreichen, vergleichsweise dicke Aussenbleche erforderlich, die die Bauplatten verteuern und das Gewicht in erwünschter
Weise erhöhen. Soll die statische Festigkeit durch eine metallische Verbindung der beiden Aussenbleche erhöht werden, so ergibt sich wieder der Nachteil, dass über die metallischen Verbindungen unerwünschte Kältebrücken entstehen. 



   Andere bekannte wärmeisolierende Bauplatten bestehen aus einer geschäumten Kernschicht, an die sich beidseitig Zwischenschichten aus geschäumtem Kunststoff geringeren spezifischen Gewichts anschliessen, wobei auf diesen Zwischenschichten metallische Deckschichten aufgeklebt sind. Wegen des Aufklebens der metallischen
Deckschichten ist jedoch ein Ausschäumen des Zwischenraumes zwischen den Deckschichten nicht möglich, so dass die Kernschicht und die Zwischenschichten in eigenen Formen hergestellt werden müssen, was ein kontinuierliches Herstellen ausschliesst. Ausserdem ergeben sich die gleichen Schwierigkeiten hinsichtlich der statischen Festigkeit wie bei den durch unmittelbares Ausschäumen hergestellten Bauplatten. 



   Der Erfindung liegt demnach die Aufgabe zugrunde, diese Mängel zu vermeiden und eine wärmeisolierende
Bauplatte, insbesondere für Kühlhäuser, zu schaffen, die einfach hergestellt werden kann und trotz geringem
Gewicht die notwendige statische Festigkeit besitzt, um auch bei grösseren Spannweiten selbsttragend eingesetzt werden zu können. 



   Die Erfindung löst die gestellte Aufgabe dadurch, dass die beiden Deckschichten jeweils aus zwei mit
Abstand voneinander angeordneten, parallel zur Plattenmittelebene verlaufenden Blechen bestehen, deren
Zwischenraum mit Kunststoffhartschaum gefüllt ist. Da die beiden Deckschichten nicht aus Blechen allein bestehen, sondern auch eine wirksame Wärmeisolierung aus Kunststoffhartschaum besitzen, braucht die Kunststoffhartschaumschichte zwischen den beiden Deckschichten nicht mehr die gesamte für die geforderte Wärmeisolation notwendige Stärke aufzuweisen, so dass die um die Stärke der   Kunststoffhartschaumfüllungen   der beiden Deckschichten verminderte Stärke der Kunststoffhartschaumschichte ohne Schwierigkeiten auch mit einer vergleichsweise kleinen und einfachen Anlage hergestellt werden kann.

   Da ausserdem jede Deckschicht zwei Bleche besitzt, deren Zwischenraum mit Kunststoffhartschaum gefüllt ist, ergibt sich durch die jeweils inneren Bleche der beiden Deckschichten eine bedeutende Erhöhung der statischen Festigkeit, die durch eine Art Verbundwirkung erzielt wird. Die Summe der Blechstärken kann daher bei gleicher statischer Festigkeit der Platten geringer sein als bei Bauplatten, die nur zwei Deckbleche besitzen. Die inneren Bleche der Deckschichten ergeben zwei zusätzliche Dampfsperren, die bei einer Beschädigung der Aussenbleche wirksam werden. 



   In weiterer Ausbildung der Erfindung kann die Kunststoffschaumfüllung der Deckschichten ein grösseres Raumgewicht als die zwischen den Deckschichten vorhandenen Kunststoffhartschaumschichten besitzen, was ebenfalls ein geringeres Gewicht der Bauplatte zur Folge hat. Durch die Wärmeisolation der vorgefertigten Deckschichten, deren Zwischenraum ausgeschäumt wird, wird ein Schrumpfen des Kunststoffhartschaumes im Bereich der Deckschichten weitgehend verhindert, so dass das Raumgewicht der Kunststoffhartschaumschichte zwischen den beiden Deckschichten geringer sein kann, als dies bei Deckschichten aus Blechen allein möglich wäre. 



   Ein weiterer Vorteil ergibt sich durch die erfindungsgemässe Bauplatte dann, wenn die Kunststoffhartschaumfüllung der Deckschichten im Bereich eines Bauplattenrandes gegenüber der mit dem Rand der Bleche abschliessenden Kunststoffhartschaumschicht zwischen den Deckschichten zurückspringt, wogegen im Bereich des gegenüberliegenden Bauplattenrandes die Kunststoffhartschaumfüllung der Deckschichten mit den Blechrändern abschliessen und die Kunststoffhartschaumschicht zwischen den Deckschichten gegenüber den Blechrändern zurückversetzt ist. Durch diese Massnahmen wird nämlich zwischen den einzelnen Bauplatten eine Art Nut-Federverbindung ermöglicht, die das Zusammensetzen der erfindungsgemässen Bauplatten wesentlich vereinfacht.

   Nut-Federverbindungen sind zwar bei Bauplatten der eingangs geschilderten Art bereits bekannt, doch können diese bekannten Nut-Federverbindungen nur durch ein entsprechendes Biegen und Kanten der beiden Deckbleche und nicht durch einfaches Weglassen des Schaumstoffkernes erreicht werden, wie dies bei einer   erfindungsgemässen   Ausführung der Bauplatten der Fall ist. Umständlich herzustellende und teure Biegeund Kantarbeiten sind daher gemäss der Erfindung nicht nötig. 



   In der Zeichnung ist der   Erfmdungsgegenstand   schematisch dargestellt. Es werden zwei   erfindungsgemässe   wärmeisolierende Bauplatten mit ihren zu verbindenden Rändern im Schnitt gezeigt.

   The invention relates to a heat-insulating building board, in particular for cold stores, with two one
Hard plastic foam layer to the outside moisture-proof covering layers.



   Such heat-insulating building panels, the cover layers of which are usually made of sheet steel, have proven to be particularly effective as additional heat insulation, the simple, continuous manufacture being rated as a particular advantage. If, however, special requirements are made with regard to thermal insulation, such as occur, for example, in cold stores, then the strength of the rigid plastic foam layer of such a building board must be increased significantly. However, building panels with thick plastic rigid foam layers between the cover layers are no longer as easy to manufacture as is possible with thinner building panels.

   In order to fill the space between the two cover sheets with foam, a comparatively large system is necessary, since the system required to produce the rigid plastic foam layer
Foam components must be made available in a corresponding amount within a short time. In addition, in order to achieve sufficient static strength of the building boards, comparatively thick outer sheets are required, which make the building boards more expensive and the weight more desirable
Way increase. If the static strength is to be increased by a metallic connection between the two outer sheets, there is again the disadvantage that undesirable cold bridges arise over the metallic connections.



   Other known heat-insulating building boards consist of a foamed core layer, to which intermediate layers of foamed plastic of lower specific weight adjoin on both sides, with metallic cover layers being glued to these intermediate layers. Because of the gluing of the metallic
Cover layers, however, it is not possible to foam the space between the cover layers, so that the core layer and the intermediate layers have to be produced in their own molds, which rules out continuous production. In addition, the same difficulties arise with regard to the static strength as with the building boards produced by direct foaming.



   The invention is therefore based on the object of avoiding these deficiencies and a heat-insulating
To create building board, especially for cold stores, which can be produced easily and despite little
Weight has the necessary static strength to be able to be used self-supporting even with larger spans.



   The invention solves the problem posed in that the two cover layers each consist of two
There are sheets which are arranged at a distance from one another and run parallel to the center plane of the plate
Space is filled with rigid plastic foam. Since the two cover layers do not consist of sheet metal alone, but also have effective thermal insulation made of rigid plastic foam, the rigid plastic foam layer between the two cover layers no longer needs to have the entire thickness required for the required thermal insulation, so that the thickness of the rigid plastic foam fillings of the two cover layers is reduced Strength of the plastic hard foam layer can be produced without difficulty even with a comparatively small and simple system.

   In addition, since each cover layer has two sheets, the space between which is filled with rigid plastic foam, the respective inner sheets of the two cover layers result in a significant increase in static strength, which is achieved by a kind of composite effect. The sum of the sheet thicknesses can therefore be less than with building boards that only have two cover sheets, with the same static strength of the panels. The inner sheets of the cover layers create two additional vapor barriers that come into effect if the outer sheets are damaged.



   In a further embodiment of the invention, the plastic foam filling of the cover layers can have a greater density than the rigid plastic foam layers present between the cover layers, which also results in a lower weight of the building board. The heat insulation of the prefabricated cover layers, the space between which is filled with foam, largely prevents the plastic rigid foam from shrinking in the area of the cover layers, so that the density of the plastic hard foam layer between the two cover layers can be lower than would be possible with cover layers made of sheet metal alone.



   A further advantage results from the building board according to the invention when the rigid plastic foam filling of the cover layers in the area of a building board edge springs back between the cover layers opposite the rigid plastic foam layer terminating with the edge of the sheet metal, whereas in the area of the opposite building board edge the plastic hard foam filling of the top layers is closed with the sheet metal edges and the Plastic hard foam layer is set back between the cover layers relative to the sheet metal edges. By means of these measures, a kind of tongue and groove connection is made possible between the individual building panels, which considerably simplifies the assembly of the building panels according to the invention.

   Tongue and groove connections are already known in building panels of the type described above, but these known tongue and groove connections can only be achieved by appropriate bending and edging of the two cover sheets and not by simply omitting the foam core, as is the case with an inventive construction of the building panels Case is. According to the invention, bending and edging work that is complicated to produce and expensive is therefore not necessary.



   The subject of the invention is shown schematically in the drawing. Two heat-insulating building panels according to the invention are shown in section with their edges to be connected.
