LEVERKU SEN-Beyerwerk Petent-AbttUun« 12. Okt. 1905LEVERKU SEN-Beyerwerk Petitioner-AbttUun « 12 . Oct 1905
Die Neuerung "bezieht sich auf einen Sandwich-Baukörper, bei dem zwischen den Deckschichten ein Hartschaumkern aus Urethangruppen enthaltendem Kunststoff angeordnet ist.The innovation "refers to a sandwich structure, in which a rigid foam core is made between the cover layers Plastic containing urethane groups is arranged.
Um Wasserdampf, der in Sandwich-Baukörp-ern mit Hartschaumkernen als Dämmetoffkern eindiffundieren kann, abzuführen und seine Kondensation bzw. Gefrieren an der kalten Außenseite zu vermeiden,;hat man Kanäle im·in Plattenform vorliegenden Schaumstoffkern in unmittelbarer Fähe der an der Außenseite des Baukörpers liegenden Deckschicht angeord-In order to dissipate water vapor, which can diffuse into sandwich structures with rigid foam cores as insulation core, and to avoid its condensation or freezing on the cold outside ; if you have channels in the foam core, which is in the form of a plate, in the immediate vicinity of the cover layer on the outside of the structure.

Ausfräsen, gebildet sind. %
net, may for example be formed mechanically, such as by milling.
Demgegenüber ist neuerungsgemäß zwischen mindestens einer der beiden Deckschichten und dem Kern ein Maschengebilde aus einem luft- und wasserdampfdurchlässigen Material angeordnet, das mit der Deckschicht in unmittelbarer Verbindung steht und in die Oberscnicht des Kernes eingebettet ist,In contrast, according to the innovation, there is a mesh structure between at least one of the two cover layers and the core made of a material that is permeable to air and water vapor and which is in direct contact with the top layer stands and is embedded in the upper surface of the core,

Die Anordnung eines Maschengebildes oder Netzwerkes zur Be- und Entlüftung ist vor allem angezeigt, wenn der Dämmstoff kern nicht in Form von fertigen Platten vorliegt, sondern direkt zwischen den Deckschichten, ggfs. kontinuierlich, durch Aufschäumung erzeugt wird, wie dies beim Polyurethan-Schaumstoff möglich ist. Das Maschengebilde oder Netzwerk wird in diesem Fall vor Durchführung des Schäumungsvorganges auf einer der beiden Deckschichten, beispielsweioe-durch Kleben, befestigt. Beim Schäumungsvorgang werden die maschenbildenden Schenkel des Netzwerkes vom Reaktionsgemisch nicht durchdrungen bzw. durchtränkt, so daß bei der so erhaltenen Verbundplatte die Entlüftung und der Wasserdampftrarisport durch das Maschengebilde oder Netzwerk weitgehend ungehindert nach allen Seiten erfolgen kann. Durch die Öffnungen zwischen den Maschenschenkeln des Netzwerkes ^ritt das Reaktiönsgemisch durch und verbindet sich iBj. Bereich dieser Öffnungen mit der Deckschicht.The arrangement of a mesh structure or network for ventilation is particularly indicated when the insulation material core is not in the form of finished panels, but directly between the cover layers, if necessary continuously, is generated by foaming, as is possible with polyurethane foam. The mesh structure or network is in this case before the foaming process is carried out on one of the two outer layers, for example, by gluing. During the foaming process the mesh-forming legs of the network are not penetrated or soaked by the reaction mixture, so that in the composite panel obtained in this way, the ventilation and the water vapor transport through the mesh structure or network can take place largely unhindered on all sides. Through the openings between the Mesh legs of the network ^ rode the reaction mixture through and connects iBj. Area of these openings with the top layer.
Als Material für das beschriebene Maschengebilde oder Netzwerk kommen u. a. offenzellige Schaumstoffe, insbesondere solche auf Polyurethan-Basis infrage, weiterhin-Pappe, bzw. Wellpappe, Vliese mit ausreichend dichter Struktur auf Basis von mineralischen, natürlichen und. synthetischen Fasern.The material used for the described mesh structure or network includes: open-cell foams, in particular Polyurethane-based ones in question, continue to be cardboard, or corrugated cardboard, fleece with a sufficiently dense structure based on mineral, natural and. synthetic fibers.

Das Maschengebilde hat vorzugsweise rechteckige Maschen. Die Maschengröße richtet sich nach dem für das Gebilde verwendeten Material sowie nach dem Aufbau der Verbundplatten und dem gewünschten Entlüftungseffekt. In der Regel werden der Schenkelabstand etwa 50 mm und Breite , bzw. Dicke der Schenkel 10 bis 15 bzw. 5 bis 10 mm betragen. The mesh structure preferably has rectangular meshes. The mesh size depends on that for the structure material used as well as the structure of the composite panels and the desired ventilation effect. In the As a rule, the leg spacing will be about 50 mm and the width or thickness of the legs 10 to 15 or 5 to 10 mm.
Das Wesentliche der vorliegenden Neuerung ist in der beiliegenden Zeichnung erläutert. Hier bedeutet« 1 den Dämmstoffkern, der vorzugsweise aus Polyurethan-Hartschaumstoff besteht, 2 das mit dem Dämmstoffkern in Verbindung stehende luft- und wasserdampfdurchlässige Maschengebilde oder Netzwerk, 3 und 4 die den Dämmstoffkern begrenzenden Deckschichten.The essentials of the present innovation are explained in the accompanying drawing. Here means « 1 the insulation core, which is preferably made of rigid polyurethane foam consists, 2 that with the insulation core in Connected air and water vapor permeable mesh structures or networks, 3 and 4 which form the insulation core delimiting top layers.
Der Sandwichkörper gemäß der Neuerung ist besonders als Dachbedeckung geeignet.The sandwich body according to the innovation is particularly suitable as a roof covering.
