Description

Die Erfindung bezieht sich auf eine Leichtbauplatte, bestehend aus einer Kernschicht und gegebenenfalls diese abdeckenden Deckschichten, wobei die Kernschicht aus einem mit Hilfe eines hydraulischen Bindemittels gebundenen, anorganische Fasern und Perlite enthaltenden Gemisch besteht. -JOThe invention relates to a lightweight panel, consisting of a core layer and optionally these covering outer layers, the core layer being made up of one with the help of a hydraulic Binder-bound, inorganic fibers and perlite-containing mixture consists. -JO

An im Leichtfassadenbau verwendeten Bauplatten werden immer höhere Anforderungen bezüglich der Wärme- und Schalldämmung, der Brandhemmung, des Gewichtes und der Festigkeit gestellt, wobei sich Maßnahmen, die für eine dieser Forderungen günstigen Einfluß ausüben, für die anderen Forderungen als ungünstig erweisen. So besitzen beispielsweise Bauplatten, deren Kern aus einer Fasermatte mit Kalziumsilikatbindung bestehen, den Vorteil, daß sie leicht sind und somit eine gute Wärmedämmung aufweisen, doch muß dabei der Nachteil einer starken Bruchneigung und einer Neigung zur Schrumpfrißbildung im Brandfall in Kauf genommen werden. Platten aus Perlite mit bituminöser Bindung verbinden wiederum den Vorteil eines guten Wärmeisoliervermögens mit dem Nachteil einer sehr geringen Eigenfestigkeit und einer Gasentwicklung bei einer entsprechenden Flammeneinwirkung. The building boards used in lightweight facade construction are subject to ever higher requirements with regard to Heat and sound insulation, fire retardancy, weight and strength provided, whereby Measures which exert a favorable influence for one of these demands, for the other demands as turn out to be unfavorable. For example, building boards have a core made of a fiber mat with calcium silicate bond exist, the advantage that they are light and thus have good thermal insulation, but must at the same time the disadvantage of a strong tendency to break and a tendency to form shrinkage cracks in the event of a fire Purchase to be taken. Plates made of perlite with bituminous bonding combine the advantage good thermal insulation properties with the disadvantage of very low intrinsic strength and gas development with a corresponding flame exposure.

Mit Kunststoffschaum mit eingeschäumten Füllstoffen als Kernschicht erhält man äußerst leichte und gut so wärmeisolierende Bauplatten, die auch eine genügende Eigenfestigkeit aufweisen, insbesondere dann, wenn sie metallische Deckschichten tragen. Der Feuerwiderstand dieser Bauplatten ist jedoch sehr gering.With plastic foam with foamed-in fillers as the core layer, you get extremely light and good heat-insulating building boards that also have sufficient inherent strength, especially if they wear metallic cover layers. However, the fire resistance of these building boards is very low.

Es sind aber auch zementartige Massen bekannt, die neben einem hydraulischen Bindemittel, Perlite und anorganischen Fasern, beispielsweise Glasfasern, hoch polymeres Material in beträchtlichem Maße enthalten. Durch dieses polymere Material soll eine bessere Spannungsübertragung zwischen der Faserverstärkung und der Masse, eine geringere Zerreibbarkeit dieser Masse und eine bessere Bindung der Masse erzielt werden. Dieses polymere Material, das für eine solche zementartige Masse von wesentlicher Bedeutung ist, setzt aber den Feuerwiderstand von den aus diesem Material hergestellten Bauplatten stark herab. Dazu kommt noch, daß auf Grund der Feinkörnigkeit der Bestandteile eine dichte und vergleichsweise schwere Bauplatte erhalten wird, was die Wärmedämmung beeinträchtigt.But there are also cement-like masses known which, in addition to a hydraulic binder, perlite and inorganic fibers, for example glass fibers, contain highly polymeric material to a considerable extent. This polymeric material is supposed to improve the transmission of tension between the fiber reinforcement and the mass, a lower friability of this mass and a better binding of the mass is achieved will. This polymeric material, essential for such a cementitious mass, but greatly reduces the fire resistance of the building boards made of this material. In addition there is also that due to the fine grain of the constituents a dense and comparatively heavy one Building board is obtained, which affects the thermal insulation.

Schließlich sind Leichtbauplatten aus Gasbeton bekannt, die einerseits Leichtzuschlagstoffe enthalten und andererseits durch Treibmittel und/oder Schaumbildner erzeugte Poren aufweisen. Durch die Kombination von Leichtzuschlagstoffen, die vorzugsweise aus geblähtem Perlite gebildet werden, und durch Treibmittel bzw. Schaumbildner erzeugte Poren im Beton kann sicherlich eine leichte Bauplatte erreicht werden, die sowohl hinsichtlich der Wärme- und Schalldämmung als auch hinsichtlich der Feuerhemmung und der Eigenfestigkeit befriedigende Ergebnisse liefert, vor allem dann, wenn anorganische Fasern hinzugefügt werden. Nachteilig bei diesem bekannten Gasbeton ist jedoch, daß die Herstellung von Bauplatten aus diesem Material wegen der erforderlichen Porenerzeugung durch Treibmittel oder Schaumbildner vergleichsweise schwierig und aufwendig ist.Finally, lightweight panels made of aerated concrete are known which, on the one hand, contain lightweight aggregates and on the other hand have pores produced by blowing agents and / or foaming agents. By combining of lightweight aggregates, which are preferably formed from expanded perlite, and propellants or foaming agent generated pores in the concrete can certainly be achieved a lightweight construction panel that both in terms of heat and sound insulation as well as in terms of fire resistance and inherent strength gives satisfactory results, especially when inorganic fibers are added. Disadvantageous in this known aerated concrete, however, is that the production of building panels from this material because of the required pore generation by blowing agents or foaming agents is comparatively difficult and is expensive.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Leichtbauplatte zu schaffen, die sowohl hinsichtlich der Wärme- und Schalldämmung als auch hinsichtlich der Feuerhemmung und der Eigenfestigkeit voll befriedigt und einfach hergestellt werden kann.The invention is therefore based on the object of creating a lightweight panel that is both in terms of Heat and sound insulation as well as with regard to fire resistance and inherent strength fully satisfied and can be easily manufactured.

Ausgehend von einer Leichtbauplatte der eingangs beschriebenen Art löst die Erfindung die gestellte Aufgabe dadurch, daß das Gemisch neben anorganischen Fasern, vorzugsweise Schlackenwollfasern, und Perlite noch grobkörniges Schaumglas mit einem Korndurchmesser bis 30 mm und feinkörniges Schaumglas mit einem Korndurchmesser von 3 bis 7 mm enthält. Durch das Vorsehen von grobkörnigem und feinkörnigem Schaumglas sowie von Perlite, das eine feine Körnung besitzt, wird erreicht, daß die Zwischenräume zwischen den grobkörnigen Schaumglasteilchen in günstiger Weise ausgefüllt werden und daß mit Hilfe des hydraulischen Bindemittels unter Einbeziehung der anorganischen Fasern eine gute Verbindung zwischen den einzelnen Bestandteilen dieses Gemisches besteht, wodurch eine ausreichende Eigenfestigkeit der Bauplatte gewährleistet wird. Da das spezifische Gewicht der verwendeten Bestandteile gering ist, besitzen auch die daraus hergestellten Leichtbauplatten ein geringes Flächengewicht, wobei auf Grund der gleichmäßigen Verteilung der Bestandteile des Gemisches eine gleichsam homogene Bauplatte erreicht wird.Starting from a lightweight panel of the type described at the outset, the invention solves the problem Object in that the mixture in addition to inorganic fibers, preferably slag wool fibers, and Perlite still coarse-grained foam glass with a grain diameter of up to 30 mm and fine-grained foam glass with a grain diameter of 3 to 7 mm. By providing coarse-grained and fine-grain foam glass and perlite, which has a fine grain size, is achieved that the gaps be filled between the coarse-grained foam glass particles in a favorable manner and that with the help of the hydraulic binder with the inclusion of the inorganic fibers a good connection between consists of the individual components of this mixture, whereby a sufficient inherent strength of the building board is guaranteed. Since the specific weight of the constituents used is low, they also have Lightweight panels made from it have a low weight per unit area, whereby due to the uniform Distribution of the constituents of the mixture a homogeneous building board, as it were, is achieved.

Eine solche erfindungsgemäße Kernschicht kann Deckschichten erhalten, die günstigerweise ausgeklebt werden. Werden als Deckschichten Deckbleche verwendet, so sollte die Oberfläche der Kernschicht möglichst glatt sein, um den Kleberverbrauch gering zu halten. Zu diesem Zweck ist es vorteilhaft, wenn die Kernschicht im Bereich ihrer Oberfläche kein grobkörniges Schaumglas enthält.Such a core layer according to the invention can contain outer layers which are advantageously glued will. If cover sheets are used as cover layers, the surface of the core layer should be as smooth as possible in order to keep the glue consumption low. For this purpose it is advantageous if the Core layer does not contain any coarse-grain foam glass in the area of its surface.

Andere Verhältnisse liegen jedoch bei der Verwendung von Gipskartonplatten als Deckschicht vor, da diese Platten mit Hilfe von Ansatzbindern befestigt werden, für die eine rauhe und porige Oberfläche wünschenswert ist.However, there are other conditions when using plasterboard as a top layer these panels are attached with the help of neck ties, for which a rough and porous surface is desirable.

Sollte die Eigenfestigkeit der erfindungsgemäßen Leichtbauplatte für bestimmte Zwecke erhöht werden, so kann in die Kernschicht bei deren Herstellung eine Armierung, beispielsweise ein Stahlgittergeflecht, ein Streckmetall oder eine Glasfiberarmierung, eingebracht werden, wobei diese Armierung natürlich im Zug- bzw. Druckbereich der Bauplatte Hegen soil.Should the inherent strength of the lightweight panel according to the invention be increased for certain purposes, for example, a reinforcement, for example a steel mesh, can be incorporated into the core layer during its production Expanded metal or a glass fiber reinforcement can be introduced, whereby this reinforcement is of course in the tensile or Print area of the building board Hegen soil.

Besonders günstige Verhältnisse erhält man, wenn nach der Erfindung die Kernschicht 10 bis 20 Vol.-%Particularly favorable ratios are obtained if, according to the invention, the core layer is 10 to 20% by volume

grobkörniges Schaumglas, 8 bis 15 Vol.-% feinkörniges Schaumglas, 40 bis 50 Vol.-°/o anorganische Fasern, 8 bis 15 Vol.-% Perlite und 4 vis 10 Vol.-% hydraulisches Bindemittel enthält.Coarse-grained foam glass, 8 to 15% by volume fine-grained Foam glass, 40 to 50% by volume inorganic fibers, 8 to 15% by volume perlite and 4 to 10% by volume hydraulic Contains binding agent.

In der Zeichnung ist der Erfindungsgegenstand schematiseh dargestellt, und zwar zeigtIn the drawing, the subject of the invention is shown schematically, namely shows

F i g. 2 eine Leichtbauplatte mit Gipskartonplatten als Deckschichten ebenfalls im Querschnitt.F i g. 2 a lightweight board with plasterboard as cover layers, also in cross section.

In der Kernschicht 1 der dargestellten Leichtbauplatte sind die schematiseh angedeuteten Bestandteile des mit einem hydraulischen Bindemittel gebundenen Gemisches, nämlich das grobkörnige Schaumglas 2, das feinkörnige Schaumglas 3, die anorganischen Fasern 4 und die Perlitekörner 5, gleichmäßig über den Querschnitt verteilt. Dadurch wird eine gleichsam homogene Bauplatte erhalten, wus sich insbesondere auf die Eigenfestigkeit günstig auswirkt.In the core layer 1 of the lightweight panel shown are the schematically indicated components of the bound with a hydraulic binder Mixture, namely the coarse-grain foam glass 2, the fine-grain foam glass 3, the inorganic fibers 4 and the perlite grains 5, evenly distributed over the cross section. This becomes one, as it were get homogeneous building board, wus has a particularly favorable effect on the inherent strength.

Gemäß F i g. 1 sind an die Kernschicht 1 Oberflächenschichten 6 angesetzt, bei denen die groben Schaumglaskörner 2 fehlen, so daß eine vergleichsweise glatte Oberfläche erhalten wird, auf die die metallischen Deckbleche 7 ohne Schwierigkeiten aufgeklebt werden können. Als Kleber eignen sich hierfür jene, die im Brandfall keine brennbaren Gase abspalten.According to FIG. 1 are attached to the core layer 1 surface layers 6, in which the coarse foam glass grains 2 are missing, so that a comparatively smooth surface is obtained on which the metallic Cover plates 7 can be glued on without difficulty. Suitable adhesives for this are those that are im Do not release any flammable gases in the event of fire.

Wie aus Fig. 2 zu entnehmen ist, können als Deckschichten auch Gipskartonplatten 8 oder andere Mineralplatten Verwendung finden, die m:t Hilfe von Ansatzklebern 9 mit der Kernschicht 1 verbunden sind. Da in einem solchen Fall eine bessere Haftung erreicht wird, wenn eine rauhe und poröse Oberfläche vorhanden ist, sind keine besonderen Oberflächenschichten vorgesehen.As can be seen from FIG. 2, plasterboard 8 or others can also be used as cover layers Mineral tiles are used which are connected to the core layer 1 with the help of attachment adhesives 9. Because in such a case better adhesion is achieved if a rough and porous surface is present, no special surface layers are provided.

LJm eine besondere Biegefestigkeit der Leichtbauplatten zu erhalten, können in den Druck- und Zugzonen der Kernschicht 1 Armierungen 10 in Form von Stahlgittergeflechten, Geweben aus Glasseide, Streckmetall od. dgl. vorgesehen werden.
Zur Herstellung einer erfindiingsgemäßen Leichtbau-In order to obtain a particular flexural strength of the lightweight construction panels, reinforcements 10 in the form of steel mesh, fiberglass, expanded metal or the like can be provided in the compression and tension zones of the core layer 1.

Danach wird dieses Gemisch mit einer entsprechenden Wassermenge angemacht und in eine Form eingebracht, wo es gegebenenfalls durch Rütteln verdichtet wird. Soll die Kernschicht durch Armierungen 10 versteift werden, so wird zuerst eine entsprechende Gemischmenge in die Form eingebracht und verteilt und dann die Armierung auf diese Schicht aufgelegt bzw. in diese Schicht eingedrückt, worauf weiteres Gemisch aufgeschüttet wird. Soll eine besonders glatte Oberfläche erhalten werden, so wird das Material der Oberflächenschichten 6 vor bzw. nach dem Einbringen des Kernschichtmaterials in die Form eingebracht.
