Description

Fassadenplatte oder Fassadenstrukturelement Facade panel or facade structure element
Die Erfindung bezieht sich auf eine Fassadenplatte oder ein Fassadenstrukturelement, wie z.B. Gesimse, Sohlbänke, Säulen, Konsolen, Fensterumrahmungen od. dgl..The invention relates to a facade panel or a facade structure element, such as e.g. Cornices, floor banks, columns, consoles, window frames or the like ..
Bekannt sind Fassadenplatten und Fassadenstrukturelemente, die aus verschiedenen Kunststoffen gebildet sind, welche an der Fassade durch etwa durch Ankleben angebracht werden und danach mit einer Beschichtung aus Mörtel überzogen werden, um diese vor Verwitterung zu schützen.Facade panels and facade structure elements are known, which are formed from various plastics, which are attached to the facade by, for example, gluing and then coated with a coating of mortar in order to protect them from weathering.
Ein Nachteil dieser Platten und Strukturelemente ist ihre relativ leichte Entflammbarkeit und ihre hohe Feuchtigkeitsaufnahme. Weiters sind Materialien, die durch Recyclingverfahren hergestellt werden, verwendet worden, die aufgrund ihrer für große Produktionsziele geringen Verfügbarkeit nur begrenzt einsetzbar sind.A disadvantage of these panels and structural elements is their relatively easy flammability and their high moisture absorption. Furthermore, materials have been used which are produced by recycling processes, which can only be used to a limited extent due to their low availability for large production goals.
Ein weiterer Nachteil der bekannten Platten und Fassadenelemente besteht darin, daß diese nach dem Anbringen noch mit einer Schutzschicht, z.B. einer Verputzschicht, überzogen werden müssen, was erfahrungsgemäß große Probleme mitsichbringt, da nach einiger Zeit Risse in der Fassenoberfläche entstehen und Stützbeläge o.a. mitaufgebracht werden müssen. Weiters ist der Beschichtungsvorgang arbeitsintensiv, muß vor Ort durchgeführt werden und ist daher nicht kostengünstig.Another disadvantage of the known panels and facade elements is that they are still covered with a protective layer, e.g. a layer of plaster must be covered, which experience has shown to cause major problems, since after some time cracks appear in the barrel surface and supporting coverings or the like must be brought along. Furthermore, the coating process is labor intensive, must be carried out on site and is therefore not inexpensive.
Aufgabe der Erfindung besteht darin, eine Fassadenplatte oder ein Fassadenstrukturelement zu schaffen, das höchsten Brandschutzbestimmungen genügt, wenig Feuchtigkeit aufnimmt, gut wärmedämmend ist und überdies ohne Rohstoffprobleme bzw. - engpässe produzierbar ist.The object of the invention is to provide a facade panel or a facade structure element that meets the highest fire protection regulations, absorbs little moisture, is good thermal insulation and can also be produced without raw material problems or bottlenecks.
Eine weitere Aufgabe der Erfindung besteht darin, eine einfach und besonders wirksame Schutzschicht für erfindungsgemäße Fassadenplatten oderAnother object of the invention is to provide a simple and particularly effective protective layer for facade panels or
Fassadenstrukturelemente anzugeben, die diese vor Verwitterung schützt und die lange Zeit beständig ist.Specify facade structure elements that protect them from weathering and that are long-lasting.
Erfindungsgemäß wird dies dadurch erreicht, daß die Fassadenplatte oder das Fassadenstrukturelement durch zementleimgebundene, frisch expandierte Teilchen, z.B. frisch aufgeschäumte Polystyrolschaumstoffteilchen, gebildet ist, und daß gegebenenfalls die Sichtfläche mit einer schutzschichtbildenden Farbe bedeckt ist.According to the invention, this is achieved in that the facade panel or the facade structure element by cement paste-bonded, freshly expanded particles, e.g. freshly foamed polystyrene foam particles is formed, and that the visible surface is optionally covered with a protective layer-forming paint.
Durch die Verwendung von z.B. zementleimgebundenen, frisch aufgeschäumten Polystyrolschaumstoffteilchen können erfindungsgemäße Fassadenplatten und Fassadenstrukturelemente in einem großtechnischen Rahmen hergestellt werden, welche eine hohe Brandhemmung hohe Wärmedämmung und eine leichte Verarbeitbarkeit aufweisen. Die schutzschichtbildene Farbe kann entweder direkt bei der Herstellung oder erst vor Ort aufgetragen werden und zeichnet sich durch eine besonders einfache Verarbeitbarkeit und besonders hohe Lebensdauer auf den erfindungsgemäßen Fassadenplatten oder Fassadenstrukturelementen aus. Die letztere Wirkung ergibt sich aufgrund der nicht glatten sondern leicht rauhen Oberfläche der erfindungsgemäßen Fassadenplatte oder Fassadenstrukturelemente, die von Poren durchbrochen ist. Dadurch ergibt sich eine sehr gute Haftung der Farbe, die aufgrund ihrer Elastizität auch nach langer Zeit keine Rißbildungen entstehen läßt. Durch diese Maßnahmen ist es möglich, auf eine Beschichtung der Platten oder Strukturelemente mit einer Verputzschicht zu verzichten. Die Farbe, die auch aufgesprüht werden kann, bewirkt auch eine Verfestigung der äußeren Schichten der Wärmedämmplatten, da durch die kapillare Saugfähigkeit die Farbe mehrere Zentimeter tief in das Innere der Platten eindringen kann. Dabei erhöht sich bei einer Behandlung der Wärmedämmplatten mit Heißluft die Haftfähigkeit eines aufgesprühten Farbauftrages, insbesondere, wenn die Flächen mit einer Haftgrundfarbe vorbehandelt wurden.By using, for example, cement paste-bonded, freshly foamed polystyrene foam particles, facade panels and facade structure elements according to the invention can be produced in a large-scale industrial framework, which have high fire resistance, high thermal insulation and are easy to process. The protective layer-forming paint can either be applied directly during production or only on site and is characterized by particularly easy processing and particularly long service life on the facade panels or facade structure elements according to the invention. The latter effect results from the non-smooth but slightly rough surface of the facade panel or facade structure elements according to the invention, which is pierced by pores. This results in very good adhesion of the paint, which due to its elasticity does not cause cracks even after a long time. These measures make it possible to dispense with coating the panels or structural elements with a plaster layer. The paint, which can also be sprayed on, also causes the outer layers of the thermal insulation boards to solidify, since the paint can penetrate several centimeters deep into the interior of the boards due to the capillary absorbency. When the thermal insulation boards are treated with hot air, the adhesiveness of a sprayed-on paint application increases, especially if the surfaces have been pretreated with a primer paint.
Weiters ergibt die Farbschicht einen sehr wirksamen Feuchtigkeitsschutz und nebenbei wird auch die optische Gestaltung der Fassade auf einfache Weise ermöglicht.Furthermore, the color layer provides a very effective moisture protection and besides, the visual design of the facade is also made possible in a simple manner.
In weiterer Ausbildung der Erfindung kann vorgesehen sein, daß die Polystyrolschaumstoffteilchen wärmevorbehandelt, insbesonders gesintert sind.In a further embodiment of the invention it can be provided that the polystyrene foam particles are heat-treated, in particular sintered.
Durch diese Maßnahmen kann eine solche Wärmedämmplatte beinahe überhaupt keine Feuchtigkeit aufnehmen, da eben die Oberflächen der Polystytrol- schaumstoff-Partikel bei der Wärmevorbehandlung verglast werden. Dabei erhöht sich durch die Versinterung der Polystyrolschaumstoff-Partikel die Festigkeit der hergestellten Wärmedämmplatten.With these measures, such a thermal insulation panel can absorb almost no moisture at all, since the surfaces of the polystyrene foam particles are glazed during the heat pretreatment. The sintering of the polystyrene foam particles increases the strength of the thermal insulation boards produced.
Weiters kann vorgesehen sein, daß die Oberflächen der beschnittenen Platte oder des Strukturelementes angeschmolzen sind.It can further be provided that the surfaces of the trimmed plate or the structural element are melted.
Dadurch wird verhindert, daß die an der Oberfläche zu liegen kommenden Polystyrolschaumstoffteilchen aus dieser leicht ausbrechen können.This prevents the polystyrene foam particles coming to lie on the surface from breaking out easily.
Nach einem anderen Merkmal der Erfindung kann vorgesehen sein, daß die frisch aufgeschäumten Polystyrolteilchen mit Normalzement oder Weißzementleim gebun¬ den sind, wodurch auch Schutzanstriche mit sonst nur sehr schlecht deckenden Farben durchgeführt und dabei die volle Schutzwirkung erhalten werden kann.According to another feature of the invention, it can be provided that the freshly foamed polystyrene particles are bound with normal cement or white cement glue, as a result of which protective coatings can also be carried out with otherwise poorly covering paints and the full protective effect can be obtained in the process.
In weiterer Ausbildung der Erfindung kann vorgesehen sein, daß die Fassadenplatten oder Fassadenstrukturelemente an den Seitenwänden nut-feder-artige Verbindungselemente aufweisen. Dadurch kann das Verlegen der Platten oder der Elemente ohne großen Aufwand und sehr schnell durchgeführt werden.In a further embodiment of the invention it can be provided that the facade panels or facade structure elements have tongue and groove-like connecting elements on the side walls. This means that the panels or elements can be laid quickly and easily.
Nach einer anderen Variante der Erfindung kann vorgesehen sein, daß die Fassadenplatte oder das Fassadenstrukturelement an ihrer bzw. seiner Sichtfläche und/oder an ihren bzw. seinen Sichträndern wenigstens zum Teil profiliert bzw. strukturiert ist.According to another variant of the invention, it can be provided that the facade panel or the facade structure element is at least partially profiled or structured on its visible surface and / or on its visible edges.
Dadurch können die Strukturierungsmaßnahmen schon bei der Herstellung vorgenommen werden und können vor Ort entfallen.This means that the structuring measures can be carried out during manufacture and can be omitted on site.
In weiterer Ausbildung der Erfindung kann vorgesehen sien, daß die schutzschichtbildende Farbe eine Dispersionsfarbe, eine mineralische Farbe, eine Farbe auf Kalkbasis, eine Kalkleimfarbe o.a. ist.In a further development of the invention, it can be provided that the protective layer-forming paint is an emulsion paint, a mineral paint, a lime-based paint, a lime glue paint or the like. is.
Diese Farben bieten aufgrund ihrer hohen Elastizität eine überaus vorteilhafte Schutzwirkung für die Fassade und sind leicht entweder bei der Herstellung der Platten oder Strukturelemente oder vor Ort auf der Fassade aufzutragen.Due to their high elasticity, these colors offer an extremely advantageous protective effect for the facade and are easy to apply either during the manufacture of the panels or structural elements or on site on the facade.
Schließlich kann ein Merkmal der Erfindung darin bestehen, daß die Fassadenplatte oder das Strukturelement eine Rohdichte von 100 bis 500 kg/m aufweist.Finally, a feature of the invention can be that the facade panel or the structural element has a bulk density of 100 to 500 kg / m.
Rohdichten in diesem Bereich haben sich als besonders vorteilhaft erwiesen, wenn eine gute Wärmedämmung und eine hohe Brandhemmung der Platten und Strukturelemente erzielt werden soll.Bulk densities in this area have proven to be particularly advantageous if good thermal insulation and high fire resistance of the panels and structural elements are to be achieved.
Im folgenden wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.The invention is explained in more detail below on the basis of exemplary embodiments.
Erfindungsgemäß ist eine Fassadenplatte oder ein Fassadenstrukturelement, wie z.B. Gesimse, Sohlbänke, Säulen, Konsolen, Fensterumrahmungen od. dgl. durch zementleimgebundene, frisch expandierte Teilchen, insbesonders frisch aufgeschäumte Polystyrolschaumstoffteilchen gebildet. Dabei sind Rohdichten im Bereich von 100 bis 500 kg/m bei einer Teilchengröße von 0,5mm bis 20 mm besonders vorteilhaft. Die Fassadenplatten sind vorteilhafterweise rechteckig und können entsprechend dem gewünschten Aussehen der Fassade bereits bei der Herstellung entprechend geformt oder nachbearbeitet werden. Besonders seitliche Profilierungen sind häufig erwünscht, welche sehr leicht durch nachträgliches Fräsen aufgebracht werden können. Erfindungsgemäße Strukturelemente können in Formen hergestellt oder entsprechend gefräst, gedreht o.a. werden. Die Verwendung von frisch aufgeschäumtem bzw. expandiertem Polystyrol als Zuschlagteilchen ermöglicht sehr hohe Produktionsmengen, die anders nur schwer erreicht werden können. Ein weiterer Vorteil dieses Rohstoffes besteht darin, daß durch geeignete Verfahren eine viel gleichemäßgigere Korngrößenverteilung erreicht werden kann, als dies mit anderen Stoffen möglich ist. Unter frisch expandierten Teilchen sind im Rahmen der Erfindung ebenso, Teilchen aus geschäumtem Mais, Perlith oder Blähton od. dgl. zu verstehen, die ebenso die vorteilhaften Wirkungen der frisch aufgeschäumten Polystyrolschaumsotteilchen aufweisen.According to the invention, a facade panel or a facade structure element such as cornices, floor banks, columns, consoles, window frames or the like is formed by cement paste-bonded, freshly expanded particles, in particular freshly foamed polystyrene foam particles. Here bulk densities in the range of 100 to 500 kg / m are particularly advantageous with a particle size of 0.5 mm to 20 mm. The facade panels are advantageously rectangular and can be shaped or reworked in accordance with the desired appearance of the facade during manufacture. Side profiles in particular are often desired, which can be applied very easily by subsequent milling. Structural elements according to the invention can be produced in molds or correspondingly milled, turned or the like. The use of freshly foamed or expanded polystyrene as aggregate particles enables very high production quantities that are otherwise difficult to achieve. Another advantage of this raw material is that by using suitable processes a much more uniform grain size distribution can be achieved than is possible with other substances. In the context of the invention, freshly expanded particles are also to be understood as meaning particles made from foamed corn, pearlite or expanded clay or the like, which likewise have the advantageous effects of the freshly foamed polystyrene foam particles.
Das Hauptverwendungsgebiet ist dabei das Renovieren bereits bestehdender Häuserfassaden, die nachträglich in ihrer Wärmedämmung und Feuchtigkeitsresistenz verbessert werden sollen. Die erfindungsgemäßen Fassadenplatten oder -Strukturelemente können nicht nur auf alte Mauer- oder Beton- oder Steinfassaden angebracht werden, sondern können besonders durch die Verwendung der frisch aufgeschäumten Polystyrolschaumstoffteilchen als Zuschlagstoff auch auf Holz-, Leichtbetonuntergrund aber auch auf Stahlkonstruktionsteilen angebracht werdenThe main area of use is the renovation of existing house facades, which are to be subsequently improved in their thermal insulation and moisture resistance. The facade panels or structural elements according to the invention can not only be attached to old masonry or concrete or stone facades, but can also be applied to wood, lightweight concrete substrates or steel parts, in particular by using the freshly foamed polystyrene foam particles as additives
Die Sichtfläche oder erforderlichfalls auch andere oder alle Oberflächenteile der Platten und Strukturelemente werden zum Zwecke des Oberflächenschutzes mit einer schutzschichtbildenden Farbe bedeckt. Dies kann entweder bereits im Herstellungsvorgang erfolgen oder erst vor Ort auf der Baustelle nachdem die Fassadenplatten oder - strukurelemente bereits angebracht worden sind.The visible surface or, if necessary, other or all surface parts of the plates and structural elements are covered with a protective layer-forming paint for the purpose of surface protection. This can either take place during the manufacturing process or only on site at the construction site after the facade panels or structural elements have already been attached.
Beondere Feuchtigeitsresistenz läßt sich errechen, indem dieSpecial moisture resistance can be calculated by the
Polystyrolschaumstoffteilchen vor dem Mischen mit Zementleim wärmevorbehandelt, insbesonders gesintert werden. Dadurch kann fast keine Feuchtigkeit mehr in das Innere der Platten oder Strukturelemnete dringen. Zur Erzeugung einer besonders glatten und stabilen Oberfläche der beschnittenen Fassadenplatte oder des Fassadenstrukturelementes wird diese als ganzes angeschmolzen, sodaß sich keine Teilchen von selbst aus ihr lösen können. Die Platten sind vorzugsweise mit Heißluft behandelt, um die angeschnittenen Poren der Polystyrolschaumstoffabfälle anzuschmelzen und zu verglasen. Durch das Anschmelzen der beschnittenen Platten wird eine Aufnahme von Wasser praktisch ausgeschlossen.Polystyrene foam particles are heat-treated, especially sintered, before mixing with cement paste. As a result, almost no moisture can penetrate into the interior of the panels or structural elements. To produce a particularly smooth and stable surface of the trimmed facade panel or the facade structure element, it is melted as a whole, so that no particles can detach from it by itself. The plates are preferably treated with hot air in order to melt and glaze the cut pores of the polystyrene foam waste. The melting of the trimmed plates practically precludes the absorption of water.
Bevorzugt als Bindemittel für die frisch expandierten Teilchen ist Normalzement oder Weißzementleim.Normal cement or white cement glue is preferred as a binder for the freshly expanded particles.
Zur leichteren Montage können die Platten bzw. Strukturelemente an ihren Seitenwänden mit Nuten versehen sein, in denen Federleisten eingesetzt sind.For easier assembly, the plates or structural elements can be provided on their side walls with grooves in which female connectors are inserted.
Die Montage der Fassadenplatten erfolgt z.B. in der Weise, daß sie mittels eines frostsicheren Klebers an die Fassade geklebt und zusätzlich mit Dübeln und Schrauben gesichert werden.The facade panels are installed e.g. in such a way that they are glued to the facade with a frost-proof adhesive and additionally secured with dowels and screws.
Die erfindungsgemäßen Fassadenplatten oder -strukrurelemente können durch Schneiden oder Fräsen ohne Schwierigkeiten auf die erforderlichen Größen zugeschnitten werden. Dabei ist es vorteilhaft, die Schnittstellen mit Heißluft zu behandeln, um die angeschnittenen Polystytrolschaumstoff-Partikel zu verglasen. Weiters können sie mit Farbe, insbesondere Dispersionsfarbe besprüht werden, wodurch die Festigkeit der Wärmedämmplatten an der behandelten Fläche steigt. Als schutzschichtbildende Farbe kann neben Dispersionsfarbe eine mineralische Farbe, eine Farbe auf Kalkbasis, eine Kalkleimfarbe , eine Farbe, welche körnige Füllstoffe enthält o.a. verwendet werden. The facade panels or structural elements according to the invention can be cut to the required sizes without difficulty by cutting or milling. It is advantageous to treat the interfaces with hot air in order to vitrify the cut polystyrene foam particles. Furthermore, they can be sprayed with paint, especially emulsion paint, which increases the strength of the Thermal insulation panels on the treated surface increase. In addition to dispersion paint, a paint that forms a protective layer can be a mineral paint, a lime-based paint, a lime glue paint, a paint that contains granular fillers or the like.
