Abstract

In a composite construction board with a core layer of light concrete produced as a pre-mix, expanded clay beads, produced by firing clay granules at above 1,000 deg C, are mixed into the core layer as light aggregate. Textile glass fibres of various lengths may be provided as an alkali resistant reinforcement of the cladding layers and/or alkali resistant glass or synthetic fibres may be added to the core layer matrix.

Description

Die Erfindung betrifft eine Verbundbauplatte mit einer Kernschicht, die beidseits von einer Deckschicht belegt ist, wobei die Kernschicht aus einem als Premix hergestellten Leichtbeton besteht.The invention relates to a composite building board with a Core layer covered on both sides by a top layer is, the core layer from a as a premix manufactured lightweight concrete.

Verbundbauplatten sind in vielfältiger Form, Ausführung und Zusammensetzung auf dem Markt. Beispielsweise zeigt das Deutsche Gebrauchsmuster 75 14 029 eine Verbundplatte, bei welcher eine Innenschicht aus Mineralfasern besteht. Diese Innenschicht ist außen jeweils verbunden mit Ze­ mentmörtel, der mit kurzen Glasfasern armiert ist. Eine derartige Verbundplatte ist als Brandschutzplatte geeig­ net, wobei die Mineralfaserschicht als Wärmedämmschicht wirkt. Anderen Belastungen, insbesondere Druck- oder Ge­ wichtsbelastungen kann sie jedoch nicht standhalten.Composite building boards come in a variety of shapes, designs and Composition in the market. For example, that shows German utility model 75 14 029 a composite panel, at which is an inner layer of mineral fibers. This The inner layer is connected to Ze on the outside cement mortar reinforced with short glass fibers. A such composite panel is suitable as a fire protection panel net, with the mineral fiber layer as a thermal insulation layer works. Other loads, especially pressure or Ge however, it cannot withstand weight loads.

Die DE-AS 12 29 439 zeigt eine Verbundplatte, bei welcher auf einer Schwerbetonschicht eine Blähbetonschicht an­ geordnet ist. Eine solche Verbundplatte weist wiederum ein erhebliches Gewicht auf. DE-AS 12 29 439 shows a composite panel in which an expanded concrete layer on a heavy concrete layer is ordered. Such a composite panel again has considerable weight.  

Ähnliches gilt auch für eine Bauplatte, wie sie in der DE-OS 28 54 228 gezeigt ist, die aus Gasbeton besteht, welcher mit Glasfasern bewehrt ist.The same applies to a building board, as in the DE-OS 28 54 228 is shown, which consists of gas concrete, which is reinforced with glass fibers.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Verbundbauplatte der oben genannten Art zu entwickeln, welche bei relativ geringem Gewicht eine hohe Druck- und Biegezugfestigkeit aufweist.The present invention has for its object a To develop composite building boards of the type mentioned above, which with a relatively low weight a high pressure and Bending tensile strength.

Zur Lösung dieser Aufgabe führt, daß in die Kernschicht als Leichtzuschlagstoff geblähte Tonperlen aus bei über 1000°C gebrannten Tongranalien eingemischt sind.To solve this problem that leads to the core layer blown clay pearls from over at Clay granules fired at 1000 ° C are mixed in.

Eine derartige Kernschicht hat nicht nur den Vorteil der höheren Druck- und Biegezugfestigkeit gegenüber bekannten Verbundbauplatten, sondern neigt auch durch die Verwendung geschlossenporigen Leichtzuschlagsstoffs im Kern zu wesentlich geringerer Wasseraufnahme. Dadurch wird zum einen ihr Gewicht nicht wesentlich erhöht und zum anderen werden Gefahren, die von einer Wasseraufnahme ausgehen, wie z. B. Aufquellen und Abnahme der Forstbeständigkeit, vermieden.Such a core layer not only has the advantage of higher compressive and bending tensile strength compared to known ones Composite building boards, but also tends through use closed-pore lightweight aggregate in the core much lower water absorption. This will become one does not significantly increase their weight and the other are dangers that arise from water absorption, such as e.g. B. swelling and decrease in forest stability, avoided.

Eine gegenüber herkömmlichen Verbundbauplatten verbesserte Biegezugfestigkeit wird durch die Bewehrung der Deckschichten mit unterschiedlich langen textilen alkaliresistenten Glasfasern erreicht, die in die Deckschichtmatrix eingebracht werden.An improved compared to conventional composite building boards Bending tensile strength is determined by the reinforcement of the Cover layers with textiles of different lengths alkali-resistant glass fibers achieved in the Top layer matrix are introduced.

Eine Verbesserung des Deck- und Kernschichtverbunds läßt sich durch Einbringen von textilen und ggf. alkaliresistenten Glas- oder Synthetikfasern in die Kernschichtmatrix erzielen.An improvement of the top and core layer composite leaves by introducing textiles and possibly alkali-resistant glass or synthetic fibers in the Achieve core layer matrix.
