Description

Die Erfindung betrifft eine Außenwand-Wärmedämmung mit einer wärmedämmenden Schicht aus zu Platten verarbeiteten mineralischen oder keramischen Fasern, wobei die Platten mit Stiften an der Außenwand befestigt sind.The invention relates to an outer wall thermal insulation with a heat-insulating layer of mineral or ceramic fibers processed into plates, the plates being fastened to the outer wall with pins.

Derartige Wärmedämmungen werden auf die Außenwände von Gebäuden aufgebracht, um den Wärmedurchgang durch die Außenwand zu verringern. Bekannt ist es, die wärmedämmende Schicht oder Platten aus wärmedämmendem Material mit Stiften an der Außenwand zu befestigen (DE-A-16 58 874, DE-A-22 34 037, DE-A-22 61 846). Aus mineralischen oder keramischen Fasern, z.B. Glasfasern oder Schlackenwolle, aufgebaute Platten besitzen jedoch insbesondere in Richtung der Plattenebene eine sehr geringe Festigkeit, insbesondere Scherfestigkeit. Man benötigt deshalb eine Vielzahl von Stiften zur Befestigung. Gleichwohl ist die Tragfähigkeit der an der Außenwand befestigten Warmedämmung gering, so daß beispielsweise kein Putz darauf aufgebracht werden kann.Such insulation is applied to the outer walls of buildings in order to reduce the heat transfer through the outer wall. It is known to attach the heat-insulating layer or plates of heat-insulating material to the outer wall with pins (DE-A-16 58 874, DE-A-22 34 037, DE-A-22 61 846). From mineral or ceramic fibers, e.g. Glass fibers or slag wool, however, built-up plates have a very low strength, in particular in the direction of the plate level, in particular shear strength. A large number of pins are therefore required for fastening. Nevertheless, the load-bearing capacity of the thermal insulation attached to the outer wall is low, so that, for example, no plaster can be applied to it.

Es ist zwar bekannt, schallisolierende oder wärmende Platten mit einer festeren Außenschicht zu versehen, indem die dort befindlichen Fasern höherverdichtet werden (BE-A-681 419), derartige Platten sind aber nicht für eine Außenwand-Wärmedämmung bestimmt. Auch in diesem Fall dürfte die Tragfähigkeit der Platten gering sein.Although it is known to provide soundproofing or warming panels with a firmer outer layer by compressing the fibers located there (BE-A-681 419), such panels are not intended for external wall thermal insulation. In this case, too, the load-bearing capacity of the panels should be low.

Im übrigen ist es bekannt, Platten aus geschäumtem Polystyrol als Wärmedämmung auf eine Außenwand aufzukleben. Derartige Platten besitzen eine hinreichende Tragfähigkeit, so daß darauf eine Putzschicht, insbesondere aus einem Kunststoff. gebundene Putz, aufgebracht werden kann. Das hat sich an sich bewährt, weil eine derartige Wärmedämmung nach einschlägigen Prüfvorschriften als schwer entflammbar eingestuft ist. Sie darf allerdings nach einschlägigen Bauvorschriften nur bis zur Höhe des 8. Geschosses eingesetzt werden. Diese Einschränkung ist aus Gründen der Feuersicherheit notwendig, weil Polystyrol zwar schwer entflammbar, aber nicht feuerfest ist. - Demgegenüber sind Glasfasern oder Schlackenwolle feuerfeste Materialien.For the rest, it is known to glue foamed polystyrene panels onto an outer wall as thermal insulation. Such plates have a sufficient load-bearing capacity, so that there is a plaster layer, in particular made of a plastic. bound plaster, can be applied. This has proven itself in itself because such thermal insulation is classified as flame retardant according to the relevant test regulations. According to the relevant building regulations, however, it may only be used up to the 8th floor. This restriction is necessary for reasons of fire safety, because polystyrene is flame retardant but not fire resistant. - In contrast, glass fibers or slag wool are refractory materials.

Aufgabe der Erfindung ist es, eine Außenwand-Wärmedämmung der eingangs beschriebenen Gattung so zu verbessern, daß sie auch größeren in Richtung der Plattenebene wirkenden Kräften standhalten kann.The object of the invention is to improve an outer wall thermal insulation of the type described in the introduction so that it can also withstand larger forces acting in the direction of the panel plane.

Diese Aufgabe wird dadurch gelöst, daß die Platten beidseitig eine Druckschicht aus einem anorganischen Material aufweisen und auf die Außenwand aufgeklebt sowie außerdem mit rostfreien und/oder feuerbeständigen, in metallischen Dübeln gehaltenen Tellerstiften befestigt sind, und daß auf die Platten eine äußere Putzschicht aufgetragen ist.This object is achieved in that the plates have a pressure layer made of an inorganic material on both sides and glued to the outer wall and are also fastened with rustproof and / or fire-resistant plate pins held in metallic dowels, and that an outer layer of plaster is applied to the plates.

Eine solche aus keramischen oder mineralischen Fasern aufgebaute wärmedämmende Schicht erfüllt ohne weiteres die Bedingungen der Brandklasse A. Sie kann deshalb ohne Verletzung der einschlägigen Bauvorschriften auch an Fassadenbereichen oberhalb des 8. Stockwerks eingesetzt werden. Die beidseitig auf die Platten aufgebrachte Druckschicht sowie die doppelte Befestigung einerseits durch Kleben und andererseits mit Stiften verbessert die Tragfähigkeit derart, daß die wärmedämmende Schicht ohne weiteres auch durch eine äußere Putzschicht belastet werden kann.Such an insulating layer made of ceramic or mineral fibers easily meets the requirements of fire class A. It can therefore also be used on facade areas above the 8th floor without violating the relevant building regulations. The pressure layer applied to the plates on both sides and the double fastening on the one hand by gluing and on the other hand with pins improves the load-bearing capacity in such a way that the heat-insulating layer can also be easily loaded by an outer plaster layer.

Es versteht sich, daß die Druckschichten aus einem anorganischen Material bestehen, welches ebenfalls in die Brandklasse A eingestuft werden kann und welches darürber hinaus als Tragschicht für den Putz sowie für das Aufbringen eines Klebers auf der Wandseite zur Verfügung stehen kann. Die Druckschicht kann eine Bewehrung aus einer Glasseidenmatte oder aus einem Metallgewebe aufweisen, wodurch ihre Festigkeit erheblich verbessert wird.It goes without saying that the printing layers consist of an inorganic material which can also be classified as fire class A and which can also be available as a base layer for the plaster and for applying an adhesive to the wall side. The pressure layer can have a reinforcement made of a glass silk mat or a metal mesh, which considerably improves its strength.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert ; es zeigt die einzige Figur einen Horizontalschnitt durch einen Teil einer Fassade mit einer Außenwand-Wärmedämmung.In the following an embodiment of the invention shown in the drawing is explained; the only figure shows a horizontal section through part of a facade with external wall thermal insulation.

Auf die Oberfläche 1 einer Außenwandung 2 eines Gebäudes ist mit einem geeigneten Kleber eine Vielzahl von Platten 3 aufgeklebt. Die Platten 3 bilden eine wärmedämmende Schicht.A large number of plates 3 are glued to the surface 1 of an outer wall 2 of a building using a suitable adhesive. The plates 3 form a heat-insulating layer.

Die Platten 3 bestehen aus mineralischen Fasern, z.B. Schlackenwolle, die zu Platten 3 verarbeitet und verfestigt sind. Beidseitig sind auf die Platten 3 Druckschichten 4 bzw. 5 mit jeweils eingelagerter Bewehrung 6 aus Glasseidengewebe aufgebracht, insbesondere aufgeklebt. Die Druckschichten 4 bzw. 5 bestehen aus einem anorganischen, feuerfesten Material.The plates 3 consist of mineral fibers, e.g. Slag wool, which are processed into plates 3 and solidified. 3 pressure layers 4 and 5, each with embedded reinforcement 6 made of glass silk fabric, are applied, in particular glued, to the plates on both sides. The printing layers 4 and 5 consist of an inorganic, refractory material.

Die Platten 3 können je nach der gewünschten Wärmedämmung eine Stärke zwischen 1 und 10 cm aufweisen. Da die Platten 3 eine verhältnismäßig geringe Scherfestigkeit, insbesondere in Richtung der Plattenebene besitzen, sind die zusätzlich zur Klebung mit rostfreien und/oder feuerbeständigen Tellerstiften 7 an der Außenwandung 2 befestigt. Die Enden der Tellerstifte 7 sind dazu in metallischen Dübeln 8 gehalten, die in die Außenwandung 2 eingelassen sind.The panels 3 can have a thickness between 1 and 10 cm depending on the desired thermal insulation. Since the plates 3 have a relatively low shear strength, in particular in the direction of the plate plane, they are attached to the outer wall 2 in addition to the gluing with rustproof and / or fire-resistant plate pins 7. For this purpose, the ends of the plate pins 7 are held in metallic dowels 8, which are embedded in the outer wall 2.

Die außenliegende Druckschicht 6 der Platten 3 dient gleichzeitig als Träger für einen darauf aufzubringenden Außenputz 9, der ein kunstharzgebundener Putz ist.The outer pressure layer 6 of the plates 3 also serves as a carrier for an outer plaster 9 to be applied thereon, which is a synthetic resin-bound plaster.

Die dargestellte Außenwand-Wärmedämmung erfüllt ohne weiteres die Bedingungen der Brandklasse A und kann deshalb auch in Fassadenbereichen oberhalb des 8. Stockwerks eingesetzt werden.The external wall thermal insulation shown easily fulfills the requirements of fire class A and can therefore also be used in facade areas above the 8th floor.
