Abstract
Wandelement als Fertigbauteil für Gebäude, mit einer ersten Schicht aus Leichtbeton, deren Oberfläche unmittelbar mit einer weiteren Schicht verbunden ist, wobei die weitere Schicht in einer Zement-Matrix eingebettete Schaumstoffkugeln enthält.Wall element as a prefabricated component for buildings, with a first layer of lightweight concrete, the surface of which is directly connected to a further layer, the further layer containing foam balls embedded in a cement matrix.
Description
Die Erfindung betrifft ein Wandelement als Fertigbauteil für Gebäude. Ein solches Fertigbauteil wird in einem Produktionsbetrieb hergestellt und dann zu dem Ort transportiert, an welchem das Gebäude in Fertigbauweise errichtet wird. Demgemäß besteht das Erfordernis, dass solche Wandelemente einen einfachen konstruktiven Aufbau haben sollen und fertigungstechnisch leicht und auch in großen Stückzahlen herstellbar sind.The invention relates to a wall element as a prefabricated component for Building. Such a prefabricated component is manufactured in a production plant and then transported to the place where the prefabricated building is established. Accordingly, there is the requirement that such wall elements have a simple constructive They should have a structure and be easy to manufacture and also in large quantities are producible.
Aus der Baupraxis ist es bekannt, ein Wandelement aus zwei Platten zusammenzusetzen, wobei eine Grundplatte aus Liapor besteht, d.h. aus Beton, der Blähton enthält. Diese Grundplatte ist mit einer Aufbauplatte verbunden, die z.B. als Liaver-Vorsatz bekannt ist. Diese Aufbauplatte enthält in Zementleim eingebundenes Recyclingglas mit Lufteinschlüssen.From construction practice it is known to assemble a wall element from two plates, one base plate consists of Liapor, i.e. made of concrete that contains expanded clay. This base plate is with connected to a build-up plate, e.g. known as a liaver is. This build plate contains recycled glass embedded in cement paste with air pockets.
Es ist weiterhin ein zusammengesetztes Wandelement bekannt, das eine Grundplatte aus Beton enthält, auf der eine Styroporplatte aufgedübelt ist. Nachteilig ist hierbei, dass durch dieses Wandelement keine Feuchtigkeit hindurchdiffundieren kann und an der Grenzschicht zwischen Styroporplatte und Betonplatte Feuchtigkeitsprobleme entstehen könnnen.It is still a composite wall element known that contains a base plate made of concrete, on which a styrofoam plate is pegged. The disadvantage here is that no moisture is caused by this wall element can diffuse through and at the boundary layer between the polystyrene plate and Concrete slab can cause moisture problems.
Es ist Aufgabe der Erfindung, ein Wandelement anzugeben, das einfach aufgebaut ist, gute bautechnische Kennwerte hat und einfach herzustellen ist.It is an object of the invention Specify wall element that is simple, good structural Has characteristic values and is easy to manufacture.
Diese Aufgabe wird für ein Wandelement als Fertigbauteil für Gebäude gelöst, wobei das Wandelement eine erste Schicht aus Leichtbeton enthält, deren Oberfläche unmittelbar mit einer weiteren Schicht verbunden ist. Diese weitere Schicht enthält in einer Zement-Matrix eingebettete Schaumstoffkugeln.This task is for a wall element as a prefabricated component for building solved, wherein the wall element contains a first layer of lightweight concrete, the surface is directly connected to another layer. This one more Layer contains in a foam matrix embedded in a cement matrix.
Gemäß der Erfindung hat das Wandelement infolge der Einbettung von Schaumstoffkugeln einen günstigen Wärmedämmwert. Weiterhin ist das gesamte Gewicht des Wandelements niedrig, so dass es sich besonders günstig für den Fertigbau von Gebäuden eignet. Ein besonderer Vorteil ist darin zu sehen, dass infolge der verwendeten Zement-Matrix ein Feuchtigkeitsausgleich über den Zementleim erfolgen kann und anders als bei dem Verbundsystem mit Styroporplatte ein Feuchtigkeitsproblem an der Grenzschicht zwischen der Schicht aus Leichtbeton und der weiteren Schicht nicht auftritt.According to the invention, the wall element has the consequence the embedding of foam balls has a favorable thermal insulation value. Furthermore, the whole Weight of the wall element low, making it particularly favorable for prefabricated buildings of buildings suitable. A particular advantage is the fact that as a result moisture balance of the cement matrix used Cement glue can be made and unlike the composite system with polystyrene plate a moisture problem at the interface between the layer from lightweight concrete and the additional layer does not occur.
Bei einem bevorzugten Ausführungsbeispiel werden als Schaumstoftkugeln expandierte Polystyrolkugeln oder Styroporkugeln verwendet. Polystyrol und Styropor sind billige Massenkunststoffe, die einfach herzustellen sind und günstige Dämmeigenschaften haben. Dieses Material gibt der weiteren Schicht den erforderlichen günstigen Wärmedämmwert. Aufgrund der Verwendung dieser Kunststoffe in Form von kleinen Kugeln bilden diese keine Diffusionssperre, so dass an den Kugeln vorbei ein Feuchtigkeitsausgleich stattfinden kann.In a preferred embodiment expanded polystyrene or polystyrene balls as foam balls used. Polystyrene and styrofoam are cheap bulk plastics, that are easy to manufacture and have good insulation properties. This Material gives the additional layer the necessary cheap Thermal insulation value. Because of the use of these plastics in the form of small balls these do not form a diffusion barrier so that past the balls moisture balance can take place.
Vorzugsweise haben die Schaumstoffkugeln einen Durchmesser von 0,5 bis 2,5 mm, vorzugsweise 0,5 bis 1,5 mm. Bei einer solchen Größe lassen sich die Schaumstoffkugeln leicht mit der Zement-Matrix vermischen, so dass das Gemisch leicht verarbeitbar ist.The foam balls preferably have one Diameter from 0.5 to 2.5 mm, preferably 0.5 to 1.5 mm. at such a size can be mix the foam balls lightly with the cement matrix, see above that the mixture is easy to process.
Ein Ausführungsbeispiel ist dadurch gekennzeichnet, dass die weitere Schicht 70 bis 90 Volumenprozent an Schaumstoffkugeln enthält, vorzugsweise 80 bis 90 Volumenprozent. Auf diese Weise ist das spezifische Gewicht dieser weiteren Schicht erheblich verringert, wodurch das gesamte Wandelement bei günstigen bautechnischen Werten ein geringes Gewicht hat.This is an embodiment characterized that the further layer 70 to 90 volume percent contains on foam balls, preferably 80 to 90 volume percent. In this way it is specific Weight of this additional layer is significantly reduced, which means that entire wall element at cheap constructional values has a low weight.
