Description

Leichtbauplatte Die Erfindung bezieht sich auf eine Leichtbauplatte, die aus einer Kernschicht und gegebenenfalls diese abdeckenden Deckschichten besteht. Lightweight panel The invention relates to a lightweight panel, which consists of a core layer and, if necessary, outer layers covering it.

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 besitzen, 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 getting higher and higher Requirements regarding heat and sound insulation, fire resistance, weight and the strength posed, taking measures appropriate to one of these demands have favorable influence for which other demands 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 therefore have good thermal insulation, but it must have the disadvantage of a strong tendency to break and a tendency to form shrinkage cracks be accepted in the event of fire. Perlite slabs with bituminous bonding combine the advantage of good thermal insulation properties with the disadvantage a very low inherent strength and a gas development with a corresponding Exposure to flame.

Mit Kunststoffschaum mit eingeschäumten Füllstoffen als Kernschichte erhält man äußerst leichte und gut 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, which also have a sufficient Intrinsic strength have, especially if they are metallic Wear top layers. However, the fire resistance of these building boards is very low.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu vermeiden und eine Leichtbauplatte zu schaffen, die sowohl hinsichtlich der Wärme- und Schalldämmung als auch hinsichtlich der Feuerhemmung und der Eigenfestigkeit voll befriedigtv Die Erfindung löst die gestellte Aufgabe dadurch, daß die Kernschichte aus einem mit Hilfe eines hydraulischen Bindemittels gebundenen, einheitlichen Gemisch von grobkörnigem Schaumglas mit einem Korndurchmesser bis 30 mm, feinkörnigem Schaumglas mit einem Korndurchmesser von 3 bis 7 mm, anorganischen Fasern, vorzugsweise Schlackenwollfasern, und Perlite besteht. 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 ausge£llt werden und daß mit Hilfe des hydraulischen Bindemittels unter Einbeziehung der an= organischen Fasern eine gute Verbindung zwischen den einzelnen Bestandteilen dieses Gemisches besteht, die eine ausreichende Eigenfestigkeit der Kernschichte gewährleistet. The invention is therefore based on the object of avoiding these shortcomings and to create a lightweight panel that is both heat and sound insulation as well as fully satisfied with regard to fire resistance and inherent strength The invention solves the problem in that the core layer consists of one with the help of a hydraulic binder bound, uniform mixture of coarse-grained foam glass with a grain diameter of up to 30 mm, fine-grained foam glass with a grain diameter of 3 to 7 mm, inorganic fibers, preferably slag wool fibers, and perlite. By providing coarse-grained and fine-grained foam glass as well as perlite, which has a fine grain size, is achieved that the gaps 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 an = organic Fibers provide a good connection between the individual components of this mixture exists, which ensures sufficient intrinsic strength of the core layer.

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.Since the specific weight of the components used is low, The lightweight panels made from it also have a low weight per unit area, due to the uniform distribution of the components of the mixture one as it were, homogeneous building board is achieved.

Eine solche erfindungsgemäße Kernschichte kann Deckschichten erhalten, die günstigerweise aufgeklebt werden. Such a core layer according to the invention can contain outer layers, which are conveniently glued on.

Werden als Deckschichten Deckbleche verwendet, so sollte die Oberfläche der Kernschichte möglichst glatt sein, um den Kleberverbrauch gering zu halten. Zu diesem Zweck ist es vorteilhaft, wenn die Kernschichte im Bereich ihrer Oberfläche kein grobkörniges Schaumglas enthält.If cover sheets are used as cover layers, the surface should 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 is in the area of its surface does not contain any coarse-grained foam glass.

Andere Verhältnisse liegen jedoch bei der Verwendung von Gipskartonplatten als Deckschichte vor, da diese Platten mit Hilfe von Ansatzbindern befestigt werden, für die eine rauhe und porige Oberfläche wünschenswert ist. However, there are other ratios when using plasterboard as a top layer, as these panels are attached with the help of tie-on 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 Kernschichte 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 liegen soll, Besonders günstige Verhältnisse erhält man, wenn nach der Erfindung die Kernschichte 10 bis 20 Vol.- grobkörniges Schaumglas, 8 bis 15 Vol.-% feinkörniges Schaumglas, 40 bis 50 Vol.-% anorganische Fasern, 8 bis 15 Vol.-Perlite und 5 bis 10 Vol.- hydraulisches Bindemittel enthält. Should the inherent strength of the lightweight panel according to the invention can be increased for certain purposes, so can in the core layers during their manufacture a reinforcement, for example a steel mesh, an expanded metal or a Fiberglass reinforcement, are introduced, with this reinforcement of course in the tensile or pressure area of the building board should be, particularly favorable conditions are obtained if, according to the invention, the core layer is 10 to 20 vol. - coarse-grained foam glass, 8 to 15% by volume of fine-grain foam glass, 40 to 50% by volume of inorganic fibers, 8 Contains up to 15 volume perlite and 5 to 10 volume hydraulic binder.

Damit die erfindungsgemäße Bauplatte die erwünschten Eigenschaften erhält, muß dafür gesorgt werden, daß die einzelnen Bestandteile des Gemisches gleichmäßig verteilt sind, so daß sich keine Anhäufungen einzelner Bestandteile ergeben. Um eine solche gleichmäßige Verteilung der einzelnen Gemischbestandteile in einfacher weise zu gewährleisten, wird in weiterer Ausbildung der Erfindung vorgeschlagen, daß die Bestandteile des Gemisches zusammen mit dem Bindemittel vor der Zugabe der nötigen Wassermenge durchgemischt werden und daß dann das mit Wasser angemachte Gemisch zum Abbinden in eine Form gebracht wird. So that the building board according to the invention has the desired properties it must be ensured that the individual components of the mixture are uniform are distributed so that there are no accumulations of individual components. Around such a uniform distribution of the individual mixture components in a simple to ensure wise, is proposed in a further embodiment of the invention, that the components of the mixture together with the binder before the addition of the necessary amount of water are mixed and that then mixed with water Mixture is brought into a mold to set.

In der Zeichnung ist der Erfindungsgegenstand schematisch dargestellt, und zwar zeigen Fig.- 1 eine erfindungsgemäße Leichtbauplatte mit metallischen Deckschichten im Querschnitt und Fig. 2 eine Leichtbauplatte mit Gipskartonplatten als Deckschichten ebenfalls im Querschnitt. The subject of the invention is shown schematically in the drawing, namely Fig. 1 shows a lightweight construction panel according to the invention with metallic cover layers in cross section and Fig. 2 shows a lightweight board with plasterboard as cover layers also in cross section.

In der Kernschichte 1 der dargestellten Leichtbauplatte sind die schematisch 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, was 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-grained foam glass 2, the fine-grained foam glass 3, the inorganic fibers 4 and the perlite grains 5, evenly over the cross section distributed. As a result, an almost homogeneous building board is obtained, which is particularly evident has a beneficial effect on inherent strength.

Gemäß Fig. 1 sind an die Kernschichte 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 hiefür jene, die: im Brandfall keine brennbaren Gase abspalten. According to FIG. 1, surface layers 6 are attached to the core layer 1, in which the coarse foam glass grains 2 are missing, so that a comparatively smooth one Surface is obtained on which the metallic cover plates 7 without difficulty can be glued on. Suitable adhesives are those that: In the event of a fire do not release any flammable gases.

Wie aus Fig. 2 zu entnehmen ist, können als Deckschichten auch Gipskartonplatten 8 oder andere Mineralplatten Verwendung finden, die mit Hilfe von Ansatzklebern 9 mit-der Kernschichte 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 can also be used as cover layers 8 or other mineral plates can be used with the help of attachment adhesives 9 are connected to the core layer 1. Because in such a case better adhesion Achieved when a rough and porous surface is present are not special Surface layers provided.

Um eine besondere Biegefestigkeit der Leichtbauplatten zu erhalten, können in den Druck- und Zugzonen der Kernschichte 1 Armierungen 10 in Form von Stahlgittergeflechten, Geweben aus Glasseide, Streckmetall od. dgl. In order to obtain a special flexural strength of the lightweight panels, can in the pressure and tension zones of the core layer 1 reinforcements 10 in the form of Steel mesh, fabrics made of glass silk, expanded metal or the like.

vorgesehen werden.are provided.

Zur Herstellung einer erfindungsgemäßen Leichtbauplatte werden zuerst die einzelnen Bestandteile des Gemisches zusammen mit dem Bindemittel in einem geeigneten Mischaggregat durchgemischt, damit eine ausreichend gleichmäßige Verteilung der einzelnen Bestandteile erreicht wird, wobei insbesondere die Schlackenwolle in Einzelfasern zerspleißt und ein Zusammenballen verhindert werden soll. Danach wird dieses Gemisch mit einer entsprechenden Wassermenge angemacht und in eine Form eingebracht, wo es gegebenenfalls durch Rütteln verdichtet wird. Soll die Kernschichte 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. To produce a lightweight panel according to the invention, first the individual components of the mixture together with the binder in a suitable Mixing unit mixed so that a sufficiently even distribution of the individual components achieved is, in particular the slag wool spliced into individual fibers and agglomeration is to be prevented. Thereafter this mixture is made up with an appropriate amount of water and poured into a mold introduced, where it is compacted by shaking if necessary. Should be the core layer are stiffened by reinforcements 10, a corresponding amount of mixture is first introduced into the mold and distributed and then the reinforcement is placed on this layer or pressed into this layer, whereupon further mixture is poured.

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. Das Aushärten und Abbinden der Bauplatte kann dabei vorteilhaft in Autoklaven geschehen.If a particularly smooth surface is to be obtained, this is the case Material of the surface layers 6 before or after the introduction of the core layer material introduced into the mold. The hardening and setting of the building board can be advantageous done in autoclaves.
