Description
Die Erfindung betrifft ein Verfahren zum Isolieren von Gebäudefassaden durch Befestigen mehrerer, 2 bis 30 cm dicker Platten aus einem harten Schaumstoff einer Dichte von 10 bis 100 g/1 auf der Fassade und anschließendem Aufbringen einer festhaftenden Putzschicht auf den Schaumstoffplatten.The invention relates to a method for insulating building facades by attaching several, 2 to 30 cm thick panels made of a hard foam with a density of 10 to 100 g / 1 on the facade and then applying a firmly adhering plaster layer on the foam panels.
Harte Schaumkunststoffe, z.B. auf Basis von Polystyrol--Partikelschaum, werden in großem Maßstab zur Isolierung von Gebäuden und Gebäudeteilen gegen den Einfluß von Kälte und Wärme eingesetzt. Bei der Isolierung von Fassaden werden die Platten mit einem festhaftenden Deckputz versehen. Durch Schwindung und/oder thermische Kontraktion der steifen Schaumstoffplatten bilden sich bei Verformungsbehinderung in Plattenebene in der Plattenebene in beiden Hauptrichtungen starke Zugkräfte aus. Diese übertragen sich auf die schubfest mit der Plattenoberfläche verbundene Deckschicht und führen dort zu Spannungen, die konzentriert über den Stoßfugen der Platten auftreten.Hard foam plastics, e.g. based on polystyrene particle foam, are used on a large scale for the insulation of buildings and parts of buildings against the influence of cold and heat. When insulating facades, the panels are provided with a firmly adhering plaster. Due to the shrinkage and / or thermal contraction of the rigid foam sheets, strong tensile forces are formed in both main directions in the plane of the board when deformation is prevented in the plane of the board. These are transferred to the cover layer, which is firmly connected to the surface of the panel, where they lead to stresses that occur concentrated over the butt joints of the panels.
Diese Spannungen überlagern sich den aus Temperaturbelastungen und Schwindung der Deckschicht selbst herrührenden Spannungen. Wird die Gesamtspannung größer als die Zugfestigkeit der Deckschicht, dann reißt diese.These stresses are superimposed on the stresses resulting from temperature loads and shrinkage of the cover layer itself. If the total tension is greater than the tensile strength of the top layer, it will tear.
Der Erfindung lag nun die Aufgabe zugrunde, die durch die Schaumstoffplatten infolge Schwindung und thermischer Längenänderung auf den Gesamtverbund und insbesondere auf die Deckschicht über den Stoßfugen ausgeübten Kräfte weitgehend zu vermindern, ohne daß jedoch die sonstigen Eigenschaften, vor allem die Wärmedämmung und die Drucksteifigkeit senkrecht zur Plattenebene negativ beeinflußt werden.The invention was based on the object of largely reducing the forces exerted by the foam sheets as a result of shrinkage and thermal change in length on the overall composite and in particular on the cover layer above the butt joints, without, however, the other properties, especially the thermal insulation and the pressure rigidity perpendicular to Plate level are negatively affected.
In der DE-A-27 08 164 ist eine rollbare Wärmedämmbahn beschrieben, die aus einer Isolierschicht aus geschäumtem Kunststoffmaterial besteht, die auf einer Abdeckbahn angeklebt ist. Die Isolierschicht weist auf der der Abdeckbahn gegenüberliegenden Seite querverlaufende Einschnitte auf, durch welche die Rollbarkeit der Wärmedämmbahn ermöglicht wird.In DE-A-27 08 164 a rollable thermal insulation sheet is described, which consists of an insulating layer made of foamed plastic material, which is glued to a cover sheet. The insulating layer has, on the side opposite the cover sheet, transverse incisions, by which the rollability of the thermal insulation sheet is made possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei dem eingangs beschriebenen Verfahren Platten verwendet werden, die mindestens auf der der Putzschicht zugekehrten Seite mit zwei Scharen parallel verlaufender Einschnitte senkrecht zur Plattenebene versehen sind, wobei die Tiefe der Einschnitte größer ist als die halbe Plattendicke, die Abstände zwischen den Einschnitten zwischen 3 und 30 cm betragen und die beiden Schnittscharen orthogonal oder unter einen Winkel von ≥ 75° zueinander verlaufen.This object is achieved in that in the method described above, plates are used which are provided at least on the side facing the plaster layer with two sets of parallel cuts perpendicular to the plane of the plate, the depth of the cuts being greater than half the plate thickness The distances between the incisions are between 3 and 30 cm and the two coulters are orthogonal or at an angle of ≥ 75 ° to each other.
Es hat sich gezeigt, daß dabei die aus behinderten Dehnungen der Platte herrührenden Kräfte in allen Richtungen der Plattenebene drastisch herabgesetzt werden, so daß - Risse in der Putzschicht, insbesondere über den Stoßfugen, vermieden werden.It has been shown that the forces resulting from disabled expansion of the board are drastically reduced in all directions of the board level, so that cracks in the plaster layer, in particular over the butt joints, are avoided.
Die Steifigkeit und Festigkeit der Schaumstoffplatten senkrecht zur Plattenebene wird durch das Schnittraster nicht verändert. Außerdem kann die bei Schaumstoffplatten notwendige Ablagerungszeit bis auf wenige Tage reduziert werden oder ganz entfallen.The stiffness and strength of the foam sheets perpendicular to the sheet plane is not changed by the cut grid. In addition, the deposition time required for foam sheets can be reduced to a few days or can be eliminated entirely.
Bevorzugte harte Schaumstoffe sind solche auf Basis von Polystyrol, insbesondere schwerentflammbarem Polystyrol--Partikelschaum. Daneben sind auch extrudierter Polystyrolschaum, Polyvinylchloridschaum und hart eingestellter Polyurethanschaum geeignet, ferner duroplastische Schäume auf Basis von Kondensationsprodukten von Harnstoff, Melamin oder Phenolen mit Formaldehyd.Preferred hard foams are those based on polystyrene, in particular flame-retardant polystyrene particle foam. In addition, there are also extruded polystyrene foam, polyvinyl chloride foam and hard-set Suitable polyurethane foam, also thermosetting foams based on condensation products of urea, melamine or phenols with formaldehyde.
Die Dicke der Schaumstoffe liegt zwischen 10 und 100 g/l, vorzugsweise zwischen 10 und 50 g/l. Die Dicke der Platten" kann zwischen 2 und 30, vorzugsweise zwischen 3 und 20 cm liegen. Die Platten sind vorzugsweise nur auf einer Seite mit den Schnittrastern versehen, und zwar auf der Seite, die im eingebauten Zustand mit der Deckschicht verbunden ist. Zur Erzielung besonderer Effekte kann es jedoch auch zweckmäßig sein, beide Seiten der Platten mit Einschnitten zu versehen. Die Einschnitte verlaufen zweckmäßigerweise senkrecht zur Plattenebene, es soll jedoch ein schräges Einschneiden, beispielsweise bis zu einem Winkel von 75° zur Plattenebene nicht ausgeschlossen werden. Die Abstände zwischen den einzelnen Einschnitten betragen 3 bis 30 cm, vorzugsweise 5 bis 20 cm, die Tiefe der Einschnitte ist größer als die halbe Plattendicke. Ist die Einschnittiefe - wie bei den in der FR-A-2 142 759 beschriebenen Schaumstoffplatten - geringer als die halbe Plattendicke, dann kann das Auftreten von Spannungen beim Verbund mit der Putzschicht nicht vermieden werden. Die Breite der eingeschnittenen Schlitze wird von der Art des Werkzeugs bestimmt. Sie kann zwischen 0 und 3 mm, vorzugsweise zwischen 0 und 1 mm, liegen; bei noch breiteren Schlitzen wird die Isolierwirkung der Dämmplatte beeinträchtigt und es können Kältebrücken entstehen.The thickness of the foams is between 10 and 100 g / l, preferably between 10 and 50 g / l. The thickness of the plates "can be between 2 and 30, preferably between 3 and 20 cm. The plates are preferably provided with the cutting grids on only one side, specifically on the side which is connected to the cover layer in the installed state. To achieve this However, it may also be useful to provide incisions on both sides of the plates with special effects The expedients are expediently perpendicular to the plane of the plate, but an oblique cut, for example up to an angle of 75 ° to the plane of the plate, should not be ruled out the individual incisions are 3 to 30 cm, preferably 5 to 20 cm, the depth of the incisions is greater than half the panel thickness, and if the incision depth - as in the foam panels described in FR-A-2 142 759 - is less than half the panel thickness , then the occurrence of tension in the bond with the plaster layer cannot be avoided slots are determined by the type of tool. It can be between 0 and 3 mm, preferably between 0 and 1 mm; If the slots are even wider, the insulating effect of the insulation board is impaired and cold bridges can occur.
Die beiden Schnittschargen verlaufen vorzugsweise orthogonal; sie können jedoch auch unter einem Winkel von 750 zueinander verlaufen.The two batches of cuts are preferably orthogonal; however, they can also run at an angle of 75 ° to one another.
Es gibt verschiedene Methoden, nach denen die Einschnitte in den Platten angebracht werden können. Als Werkzeuge kommen z.B. Sägen, Schneidringe, rotierende Messer, Glühdrähte oder oszillierende Drähte in Frage. Es ist auch möglich, mit Einschnitten versehene Schaumstoffplatten direkt nach dem Formteilverfahren herzustellen, indem man Formen mit eingebauten dünnwandigen Blechen verwendet.There are various methods by which the incisions can be made in the panels. As tools saws, cutting rings, rotating knives, glow wires or oscillating wires are possible. It is also possible to produce foam sheets with incisions directly by the molding process, using molds with built-in thin-walled sheets.
Die geschlitzten Schaumstoffplatten können wie herkömmliche Dämmstoffe an den Rändern gefalzt werden. Sie werden erfindungsgemäß mit einer - gegebenenfalls armierten - Putzschicht versehen.The slotted foam panels can be folded around the edges like conventional insulation. According to the invention, they are provided with a plaster layer, optionally reinforced.
Auf ein 24 cm dickes Kalksandsteinmauerwerk wird die erfindungsgemäße Wärmedämmschicht mit einem üblichen Baukleber aus einer Kunstharzdispersion mit Zementzusatz aufgeklebt. Die Dämmschicht besteht aus 8 cm dicken, 50 cm breiten und 100 cm langen Platten aus schwerentflammbarem Schaumpolystyrol einer Dichte von 15 g/l. Die Platten sind mit zwei orthogonalen Scharen von 6 cm tiefen Einschnitten versehen, die Abstände von 10 cm haben (s. Zeichnung). Auf die Dämmschicht wird ein Grundputz einer Dicke von 5 mm aufgetragen, in den mittig ein Glasseidengittergewebe als Armierung eingebettet ist. Nach Erhärten des Grundputzes wird als Deckputz ein kunstharzgebundener Reibeputz in 3 mm Dicke aufgebracht.The thermal insulation layer according to the invention is glued onto a 24 cm thick sand-lime brick masonry using a conventional construction adhesive made from a synthetic resin dispersion with cement additive. The insulation layer consists of 8 cm thick, 50 cm wide and 100 cm long sheets of flame-retardant foam polystyrene with a density of 15 g / l. The plates are provided with two orthogonal panels with 6 cm deep incisions that are 10 cm apart (see drawing). A base plaster with a thickness of 5 mm is applied to the insulation layer, in the middle of which a glass fiber mesh fabric is embedded as reinforcement. After the base plaster has hardened, a synthetic resin-bonded rubbing plaster with a thickness of 3 mm is applied.
Man erhält eine Fassadenaußendämmung, bei der im Gegensatz zu konventionell aufgebauten Dämmungen auf Basis von unbehandelten Schaumstoffplatten keine Spannungsspitzen über den Stoßfugen der Platten auftreten, so daß das Risiko der Rißbildung in den Deckschichten weitgehend ausgeschaltet ist.An outer facade insulation is obtained in which, in contrast to conventionally constructed insulation based on untreated foam panels, no stress peaks occur over the butt joints of the panels, so that the risk of cracks in the outer layers is largely eliminated.
