Description

Die Erfindung betrifft eine Außenwand - Wärmedämmung mit einer auf die Außenwand geklebten Schicht aus wärmedämmendem Material, einer darauf aufgebrachten, ggf. bewährten Druckschicht und einer äußeren Putzschicht.The invention relates to an outer wall - thermal insulation with a layer of heat-insulating material glued to the outer wall, a possibly approved pressure layer applied thereon and an outer plaster layer.

Derartige Wärmedämmungen werden auf die Außenwände von Gebäuden aufgebracht, um den Wärmedurchgang durch die Außenwand zu verringern. Die eigentliche Wärmedämmung übernimmt dabei die mit einem geeigneten Kleber auf die Außenwand geklebte Schicht aus wärmedämmendem Material, das bei einer bekannten Ausführungsform aus geschäumtem Polystyrol besteht. Außenseitig trägt die wärmedämmende Schicht die darauf ggf. aufgeklebte Druckschicht, die die Grundlage für den Außenputz bildet, der in der Regel ein kunststoffgebundener Putz ist. - Die insoweit bekannte Wärmedämmung hat sich an sich bewährt, sie ist nach einschlägigen Prüfvorschriften als "schwer entflammbar" eingestuft und darf nach einschlägigen Bauvorschriften bis zur Höhe des achten Geschosses eingesetzt werden. Diese Einschränkung ist aus Gründen der Feuersicherheit notwenig, weil die bekannte Wärmedämmung zwar schwer entflammbar aber nicht feuerfest ist.Such insulation is applied to the outer walls of buildings in order to reduce the heat transfer through the outer wall. The actual thermal insulation is carried out by the layer of heat-insulating material which is glued to the outer wall with a suitable adhesive and, in a known embodiment, consists of foamed polystyrene. On the outside, the heat-insulating layer carries the pressure layer that may be glued to it, which forms the basis for the exterior plaster, which is usually a plastic-bound plaster. - The known thermal insulation has proven itself per se, it is classified as "flame retardant" according to the relevant test regulations and may be used up to the height of the eighth floor according to the relevant building regulations. This restriction is necessary for reasons of fire safety, because the known thermal insulation is difficult is flammable but not fireproof.

Aufgabe der Erfindung ist es, eine Wärmedämmung der eingangs beschriebenen Gattung so zu verbessern, daß sie die Bedingungen der Brandklasse A erfüllt.The object of the invention is to improve thermal insulation of the type described above so that it meets the conditions of fire class A.

Diese Aufgabe wird dadurch gelöst, daß die wärmedämmende Schicht aus mineralischen oder keramischen Fasern besteht, die zu Platten, Matten od.dgl. verarbeitet bzw. verfestigt sind und daß die Matten, Platten od.dgl. zusätzlich mit Stiften od.dgl. an der Wand befestigt sind.This object is achieved in that the heat-insulating layer consists of mineral or ceramic fibers or the like to form plates, mats. processed or solidified and that the mats, plates or the like. additionally with pens or the like. are attached to the wall.

Die aus keramischen oder mineralischen Fasern aufgebaute wärmedämmende Schicht erfüllt ohne weiteres die Bedingungen der Brandklasse A und kann deshalb ohne Verletzung der einschlägigen Bauvorschriften auch an Fassadenbereichen oberhalb des achten Stockwerks eingesetzt werden. Als Materialien eignen sich insbesondere Matten, Platten od.dgl. aus Glasfasern oder aus Schlackenwolle. Weil Platten, Matten od.dgl. aus derartigen Materialien jedoch eine verhältnismäßig geringe Festigkeit, insbesondere Scherfestigkeit besitzen, werden sie zusätzlich mit Stiften od.dgl. an der Wand befestigt, damit sie auch größeren in Richtung der Platten -bzw. Mattenebene wirkenden Kräften standhalten können.The insulating layer made of ceramic or mineral fibers easily fulfills the requirements of fire class A and can therefore be used on facade areas above the eighth floor without violating the relevant building regulations. Mats, plates or the like are particularly suitable as materials. made of glass fibers or slag wool. Because plates, mats or the like. from such materials, however, have a relatively low strength, in particular shear strength, they are additionally or the like with pins. attached to the wall, so that they are also larger in the direction of the panels. Can withstand forces acting on the mat level.

Vorteilhaft sollte die wärmedämmende Schicht wenigstens einseitig, insbesondere aber beidseitig, eine Druckschicht aus einem anorganischen Material aufweisen, das natürlich auch in die Brandklasse A eingestuft werden kann, so daß die Matten oder Platten auch während des Transportes und der Montage gegen äußer Beanspruchungen geschützt sind und darüberhinaus eine entsprechende Tragschicht für den Putz sowie ggf. für das Aufbringen eines Klebers auf der Wandseite zur Verfügung steht. Die Druckschicht kann eine Bewehrung aus einer Glasseidenmatte oder aus einem Metallgewebe aufweisen, wodurch ihre Festigkeit erheblich verbessert wird.The heat-insulating layer should advantageously have, at least on one side, but in particular on both sides, a pressure layer made of an inorganic material, which of course can also be classified as fire class A, so that the mats or panels are also protected against the outside during transport and assembly Stresses are protected and there is also a corresponding base layer for the plaster and possibly 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.

Zweckmäßig wird die wärmedämmende Schicht mit rostfreien und/oder feuerbeständigen Tellerstiften an der Wand befestigt, wobei die Tellerstifte in metallischen Dübeln gehalten sein sollten. Auch diese Befestigung erfüllt die Bedingungen der Brandklasse A.The heat-insulating layer is expediently fastened to the wall with rustproof and / or fire-resistant plate pins, the plate pins should be held in metallic dowels. This fastening also meets the requirements of fire class A.

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.An exemplary embodiment of the invention illustrated in the drawing is explained below; 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. On both sides, 3 pressure layers 4 and 5, each with embedded reinforcement 6 made of glass silk fabric, are applied, in particular glued, to the plates. 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 sie zusätzlich zur Klebung mit rostfreiem 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 plates 3 can, depending on the desired heat insulation between 1 and 10 cm thick. 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 kunsthartgebundener 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 an art-hard plaster.

Die dargestellte Außenwand-Wärmedämmung erfüllt ohne weiteres die Bedingungen der Brandklasse A und kann deshalb auch in Fassadenbereichen oberhalb des achten Stockwerkes 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 eighth floor.
