Abstract
Description
Die Erfindung bezieht sich auf eine Wärmedämmplatte für Fassaden.The invention relates to a thermal insulation panel for facades.
Bekannt sind Wärmedämmungen an Fassaden, bei welchen Polystyrol-Hartschaumplatten oder extrudierte Schaumplatten an Fassaden geklebt und dann beschichtet werden. Auch werden Fassaden mittels Glasfaser- oder Steinwollematten, welche an der Fassade mittels Lattenrostes und nachträglicher Witterungsschutzverkleidung befestigt sind, vor zu rascher Auskühlung geschützt.Thermal insulation on facades is known in which polystyrene rigid foam panels or extruded foam panels are glued to facades and then coated. Facades are also protected against rapid cooling by means of glass fiber or rock wool mats, which are attached to the facade by means of slatted frames and subsequent weather protection cladding.
Diese und ähnliche Maßnahmen eignen sich jedoch aus Sicherheitsgründen nicht für hohe Fassaden, insbesondere nicht für die nachträgliche Sanierung von Hochhäusern aus Schwerbeton-Fertigteilen.For safety reasons, however, these and similar measures are not suitable for high facades, especially not for the subsequent renovation of high-rise buildings made of precast concrete.
Aus Gründen der Brandsicherheit wird vielfach der Einsatz von Schaumstoffplatten - ab etwa acht Metern über Grund - als Fassadenschutz nicht mehr erlaubt (z.. in Deutschland). Auch besteht bei dem Einsatz von Steinwolle oder Glaswolle der Einwand, daß nämlich im Falle der Durchfeuchtung dieser Wandverkleidung einerseits die Wärmedämmeigenschaft verloren geht, und dabei andererseits das Eigengewicht der wassergetränkten Fassadenverkleidung so hoch werden kann, daß die Halterungen dieser Kontruktion nicht mehr imstande sind, diese Lasten aufzunehmen, wobei Absturzgefahr für diese Konstruktion entstehen kann. Es sei auch an die im Falle der Eisbildung entstehenden Gefahren hingewiesen.For reasons of fire safety, the use of foam panels - from about eight meters above ground - as facade protection is no longer permitted (e.g. in Germany). There is also the objection to the use of stone wool or glass wool that if this wall covering is moistened, the thermal insulation property is lost on the one hand, and on the other hand the weight of the water-soaked facade cladding can become so high that the brackets are no longer able to carry out this construction Take up loads, which may result in a fall for this construction. Attention is also drawn to the dangers arising from the formation of ice.
Auch die nachträgliche Errichtung von hinterfülltem Vorsatzmauerwerk ist in den meisten Fällen zwecks Herstellung einer "betriebssicheren" Wärmedämmfassade, insbesondere bei Hochhäusern, nicht wirtschaftlich möglich. Bei Neubauten wird dieses System angewendet, wobei als Füllstoff für die Erzielung des Wärmedämmeffektes jegliche Art von Leichtbauhilfsstoffen verwendet wird.The subsequent erection of backfilled facing masonry is not economically feasible in most cases for the purpose of producing a "reliable" thermal insulation facade, especially in high-rise buildings. This system is used in new buildings, whereby any kind of lightweight construction aid is used as a filler to achieve the thermal insulation effect.
Die bekannten Wärmedämmsysteme zur Verbesserung der Wärmedämmung von Fassaden weisen darüberhinaus den Nachteil auf, daß dieselben nach deren Errichtung eine flächendeckende Beschichtung brauchen, um einerseits zu verhindern, daß Feuchtigkeit in die Dämmstoffe dringt, und daß andererseits die Fassade ein ansehnliches Äußeres erhält. Außerdem bedarf eine sogenannte "Vollwärmeschutzfassadenverkleidung" aus expandiertem Polystyrolschaum auch eines Schutzüberzuges aus Baukleber mit Gewebeeinlage, damit die brennbare Schaumstoffmasse vor Brandeinwirkung geschützt ist, und damit andererseits die Schaumstoffmasse vor UV-Strahlung geschützt wird. Weiters ist der Schutzüberzug erforderlich, um mechanische Angriffe von außen her abzuwehren. Ebenso erfüllt der Schutzüberzug die Aufgabe, den erforderlichen Farbanstrich der Fassade aufzunehmen.The known thermal insulation systems for improving the thermal insulation of facades also have the disadvantage that they need a full-coverage coating after they have been erected, on the one hand to prevent moisture from penetrating into the insulating materials, and on the other hand that the facade has a good appearance. In addition, a so-called "full heat protection facade cladding" made of expanded polystyrene foam also requires a protective coating made of construction adhesive with a fabric insert, so that the combustible foam mass is protected against the effects of fire and, on the other hand, the foam mass is protected against UV radiation. The protective coating is also required to ward off mechanical attacks from the outside. The protective coating also fulfills the task of absorbing the required color of the facade.
Es ist dabei erforderlich, daß alle Abdeckungen oder Schutzüberzüge der Fassadenwärmedämmsysteme äußerst exakt verarbeitet werden müssen, weil jede kleinste Unebenheit, jeder kleinste Haar-Riß usw. für das freie Auge sofort erkennbar ist. Dabei können nun beispielsweise an Gebäude-Außenseiten Stoßfugen von Betonfertigteilen von aus Großbetontafeln errichteten Gebäuden nicht dauerhaft rißfrei verkleidet werden. Denn die Gewebearmierung eines "Schutzüberzuges" kann die Dehn- und Schwindkräfte der Beton-Fertigteile nicht aufnehmen, sodaß von vorneherein dort Risse zu erwarten sind.It is necessary that all covers or protective coatings of the facade insulation systems must be processed extremely precisely, because every slight bump, every smallest hair crack, etc. is immediately visible to the naked eye. Here, for example, butt joints of precast concrete parts of buildings constructed from large concrete panels cannot be permanently clad without cracks on the outside of the building. Because the fabric reinforcement of a "protective covering" cannot absorb the expansion and shrinkage forces of the precast concrete parts, so that cracks can be expected there from the start.
Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Wärmedämmplatte der eingangs erwähnten Art vorzuschlagen, die sich einfach herstellen und montieren läßt.The aim of the invention is to avoid these disadvantages and to propose a thermal insulation panel of the type mentioned at the outset, which can be easily manufactured and assembled.
Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention this is achieved by the characterizing features of
Solche erfindungsgemäßen Wärmedämmplatten zeichnen sich durch ein hohes Maß an Wärmedämmung aus und sind leicht montierbar. So können solche Wärmedämmplatten mit Dübeln und Kleben befestigt werden. Außerdem ist durch Bindung der Polystyrolschaurnstoffabfälle mit Zementleim auch gewährleistet, daß es zu keinem Ansaugen mit Wasser kommt. Weiters ist bei der vorgeschlagenen Wärmedämmplatte Frostsicherheit gewährleistet, wobei diese Platten leicht bearbeitbar sind, da sie nicht spröde sind. Mit den erfindungsgemäßen Wärmedämmplatten lassen sich auch Fassaden von Hochhäusern verkleiden. Dabei eignen sich die vorgeschlagenen Platten ab einer Dicke von ca. 15cm auch als Brandschutzplatten, mit denen auch Stahlbetonunterzüge vor Brandschäden geschützt werden können.Such thermal insulation boards according to the invention are characterized by a high degree of thermal insulation and are easy to assemble. Such thermal insulation boards can be attached with dowels and glue. In addition, the binding of the polystyrene foam waste with cement paste also ensures that there is no suction with water. Furthermore, frost protection is ensured with the proposed thermal insulation board, these boards being easy to work with since they are not brittle. Facades of high-rise buildings can also be clad with the thermal insulation panels according to the invention. The proposed panels from a thickness of approx. 15 cm are also suitable as fire protection panels with which reinforced concrete beams can also be protected against fire damage.
Außerdem ergibt sich durch die vorgeschlagenen Wärmedämmplatten auch der Vorteil, daß anfallende Polystytrolschaumstoffabfälle sehr günstig verwertet werden können, wodurch eine Entlastung der Umwelt erreicht wird. So können z.B. Schaumstoffverpackungen zerkleinert werden.In addition, the proposed thermal insulation panels also have the advantage that the resulting polystyrene foam waste can be used very cheaply, thereby relieving the burden on the environment. For example, Foam packaging can be shredded.
Der Aufwand für die Herstellung einer Wärmedämmung für eine Fassade mit den erfindungsgemäßen Wärmedämmplatten ist auch aufgrund der einfachen Montage geringer als bei den bekannten Systemen, wobei darüber hinaus die Fassade eine Strukturierung erfahren kann, da die verwendeten Materialien bestehenden Wärmedämmplatten zumeist schon vor deren Montage mit Profilierungen versehen werden können.The effort for the production of thermal insulation for a facade with the thermal insulation boards according to the invention is also lower than in the known systems due to the simple assembly, and in addition the facade can be structured, since the materials used exist mostly with thermal insulation boards before they are assembled with profiles can be provided.
Durch die Merkmale des Anspruches 2 ergibt sich der Vorteil, daß eine solche Wärmedämmplatte praktisch kein Wasser aufnehmen kann, da eben die Oberflächen der Polystytrolschaumstoff-Partikel verglast sind. Dabei erhöht sich durch die Versinterung der Polystyrolschaumstoff-Partikel die Festigkeit der hergestellten Wärmedämmplatten. Dabei kann bei der Herstellung der Wärmedämmplatten den Polystyrol-Partikel geringe Mengen an Verflüssigern bzw. Luftporenbildnern beigemengt werden.Due to the features of
Die erfindungsgemäßen Wärmedämmplatten lassen sich sehr leicht z.B. durch Fräsen bearbeiten, sodaß z.B. Quaderplatten mit beispielsweise den Formaten 40cm x 80cm x 15cm an allen vier Rändern außenseitig mit Kantenprofilierungen versehen werden. Dabei brauchen die Platten lediglich an der Fassade befestigt zu werden.The thermal insulation boards according to the invention can be very easily e.g. machining by milling so that e.g. Cuboid panels with, for example, the formats 40cm x 80cm x 15cm are provided with edge profiles on the outside on all four edges. The panels only need to be attached to the facade.
Durch die Merkmale des Anspruches 3 ergibt sich der Vorteil, daß ein Ausbrechen von Partikel aus den Schnittflächen verhindert wird.The features of
Durch die Bindung der Polystyrolschaurnstoff-Partikel mit Weißzementleim ergibt sich der Vorteil, daß die Platten mit wenig deckenden Färbelungen versehen werden können.By binding the polystyrene foam particles with white cement glue there is the advantage that the plates can be provided with less opaque colorations.
Durch die Merkmale des Anspruches 5 ergibt sich eine besonders einfache Montage.The features of
Ein weiteres Ziel der Erfindung ist es, ein Verfahren zur Dämmung einer Fassade unter Verwendung erfindungsgemäßer Wärmedämmplatten vorzuschlagen, das ein einfaches Montieren der Dämmplatten ermöglicht.Another object of the invention is to propose a method for insulating a facade using thermal insulation boards according to the invention, which enables simple mounting of the insulation boards.
Erfindungsgemäß wird dies durch die Merkmale des Anspruches 6 erreicht. Dabei ergibt sich durch die vorgeschlagene Montage eine sehr sichere Befestigung der Wärmedämmplatten.According to the invention this is achieved by the features of
Durch die Merkmale des Anspruches 7 ist es möglich auf eine Beschichtung mit Platten zu verzichten werden. Die Farbe, die auch aufgesprüht werden kann und eine Dispersionsfarbe sein kann, bewirkt auch eine Verfestigung der äußeren Schichten der Wärmedämmplatten, da durch die kapillare Saugfähigkeit des Leichtbeton-Zementgehaltes die Dispersionsflüssigkeit mehrere Zentimeter tief in das Innere der Platten eindringen kann. Somit können auch ganz leichte Platten, z.B. mit einer Rohdichte von nur 0,2kg/l zur Wärmedämmung von Fassaden verwendet werden. Dabei erhöht sich bei einer Behandlung der Wärmedämmplatten mit Heißluft die Haftfähigkeit eines aufgesprühten Farbauftrages, insbesondere, wenn die Flächen mit einer Haftgrunddispersion vorbehandelt wurden.The features of
Durch die Merkmale des Anspruches 8 ergibt sich eine besonders einfache Montage der Wärmedämmplatten.The features of

Die Platten 1 weisen eine Rohdichte von 0,2 bis 0,35kg/l auf, wobei die Wärmeleitzahl ca. 0,065 W/mK beträgt. Bei Dicken der Wärmedämmplatte 1 von 16 bis 18cm ergibt sich dabei ein K-Wert von ca. 0,4W/m2K. Bei einer mit den erfindungsgemäßen Wärmedämmplatten verkleideten Fassade ergibt sich eine Verminderung des Heizenergieaufwandes bis zu 40%. Dabei weisen die Polystyrolschaumstoff-Partikel eine Korngröße von 2 bis 5mm auf.Fig. 1 shows a
Die Wärmedämmplatten 1 sind vorzugsweise mit Heißluft behandelt, um die angeschnittenen Poren der Polystyrolschaumstoffabfälle anzuschmelzen und zu verglasen. Dadurch wird eine Aufnahme von Wasser praktisch ausgeschlossen.The
Die Wärmedämmplatten 1 weisen durch Fräsen hergestellte Profilierungen 2 auf. Weiters zeigt die Fig. 2 die Dübelbohrungen 3 an den Seitenwänden 4 der Wärmedämmplatte 1.
