Abstract

The wall cladding has several horizontally spaced vertical support strips (2) fixed to the building wall (1). Between the strips are arranged several plate-type insulating material components (4) fitted to the wall. On the outer surfaces of the strips are support plates (6) which have a weather protection layer on the outer side. There is an air gap of at least 20 mm between the components and the inside of the support plates. The support strips are made of mineral wool plates and are adhered with their inner surfaces (2a) to the building wall with the wool fibres running normal to the wall. The plates are adhered to the outer surfaces (2b) of the strips and are also connected by screws (11) which extend through the strips into the building wall.

Description

Die Erfindung betrifft eine vorgehängte, hinterlüftete Außenwandbekleidung mit mehreren an der Gebäudewand befestigten, in horizontalem Abstand voneinander angeordneten, vertikalen Tragleisten, mit mehreren zwischen den Tragleisten angeordneten, an der Gebäudewand angebrachten plattenartigen Dämmstoffelementen und mit mehreren an den Außenflächen der Tragleisten anliegenden Trägerplatten, an deren Außenseite eine Wetterschutzschicht angeordnet ist, wobei die Dicke der Dämmstoffelemente und der Abstand der Außenflächen der Tragleisten von der Gebäudewand so bemessen sind, daß zwischen den Dämmstoffelementen und der Innenseite der Trägerplatten ein Luftspalt von mindestens 20 mm vorhanden ist.The invention relates to a curtain-type, rear-ventilated outer wall cladding with a plurality of vertical support strips fastened to the building wall and arranged at a horizontal spacing from one another, with a plurality of plate-like insulation elements arranged between the support strips and attached to the building wall and with a plurality of support plates resting on the outer surfaces of the support strips, on the other A weather protection layer is arranged on the outside, the thickness of the insulation elements and the distance between the outer surfaces of the support strips from the building wall being such that there is an air gap of at least 20 mm between the insulation elements and the inside of the support plates.

Bei einer derartigen bekannten Außenwandbekleidung (siehe z.B. Firmenschrift "StoVerotec Fassade 2000", der Firma Sto AG, D-79780 Stühlingen, bestehen die vertikalen Tragleisten aus Holz. Diese Tragleisten können auf verschiedene Art mit der Gebäudewand verbunden werden. Es sind zu diesem Zweck Aluminium-Wandhalter vorgesehen, die jeweils mittels einer Schraube mit der Gebäudewand verbunden werden und die ihrerseits mit jeweils einer Aufnahmegabel für die Holzleiste verschraubt werden können. Die Holzleiste wird dann wiederum durch Schrauben mit der Aufnahmegabel verbunden. Abgesehen davon, daß die Aluminium-Wandhalter mit den Aufnahmegabeln verhältnismäßig teuer in der Herstellung sind, ist auch der Montageaufwand verhältnismäßig groß. Außerdem wird keine gute Schallisolierung erreicht. Die gleichen Nachteile hat auch eine andere Bauart dieser bekannten Außenwandbekleidung, bei der zunächst an der Gebäudewand horizontale Konterlatten aus Holz in einem gegenseitigen Abstand von etwa 600 mm befestigt werden. Zwischen diese Konterlatten werden dann die Dämmstoffelemente, meistens Mineralstoffplatten oder -matten, eingelegt und mit der Gebäudewand verbunden. Auf die Konterlatten werden dann die vertikalen, aus Holz bestehenden Tragleisten aufgeschraubt oder aufgenagelt. Da die Dicke der Konterlattung der Dicke der Dämmstoffelemente entspricht, ist die Holz-Unterkonstruktion vom Material her verhältnismäßig teuer und erfordert ebenfalls einen hohen Montageaufwand. Auch die Schalldämmung ist unbefriedigend.In such known external wall cladding (see, for example, company name "StoVerotec facade 2000", from Sto AG, D-79780 Stühlingen), the vertical support strips are made of wood. These support strips can be connected to the building wall in various ways - Wall brackets are provided, which are each connected to the building wall by means of a screw and which in turn can be screwed together with a holding fork for the wooden bar. The wooden bar is then in turn connected with screws to the holding fork. Apart from the fact that the aluminum wall bracket with the Mounting forks are relatively expensive to manufacture, the assembly effort is also relatively large. In addition, good sound insulation is not achieved. The same disadvantages also have another design of this known outer wall cladding, in which horizontal counter battens made of wood are first attached to the building wall be fixed at a mutual distance of about 600 mm. The insulation elements, mostly mineral slabs or mats, are then inserted between these counter battens and connected to the building wall. The vertical, wooden support strips are then screwed or nailed onto the counter battens. Since the thickness of the counter battens corresponds to the thickness of the insulation elements, the wooden substructure is relatively expensive in terms of material and also requires a lot of assembly work. Soundproofing is also unsatisfactory.

Der Erfindung liegt daher die Aufgabe Zugrunde, eine vorgehängte, hinterlüftete Außenwandbekleidung der eingangs erwähnten Art zu schaffen, die kostengünstig herstellbar ist und dabei neben der Wärmeisolierung auch eine gute Schalldämmung aufweist.The invention is therefore based on the object of providing a curtain-type, rear-ventilated outer wall covering of the type mentioned at the outset, which is inexpensive to produce and which, in addition to the thermal insulation, also has good sound insulation.

Dies wird nach der Erfindung dadurch erreicht, daß die Tragleisten aus Mineralwolleplatten gefertigt und mit ihren Innenflächen so an die Gebäudewand angeklebt sind, daß die Mineralwollefasern im wesentlichen senkrecht zur Gebäudewand verlaufen, daß die Trägerplatten an die Außenflächen der Tragleisten geklebt und zusätzlich über Schrauben oder dgl., die sich durch die Tragleisten hindurch bis in die Gebäudewand erstrecken, mit dieser verbunden sind, und daß die Höhe der Tragleisten senkrecht zur Gebäudewand um mindestens 20 mm größer ist als die Dicke der Dämmstoffelemente.This is achieved according to the invention in that the support strips are made of mineral wool panels and are glued with their inner surfaces to the building wall in such a way that the mineral wool fibers run essentially perpendicular to the building wall in that the carrier plates are glued to the outer surfaces of the support strips and additionally by screws or the like ., Which extend through the support strips into the building wall, are connected to it, and that the height of the support strips perpendicular to the building wall is at least 20 mm greater than the thickness of the insulation elements.

Die Erfindung geht also von dem Gedanken aus, Streifen von Mineralwolleplatten abzuschneiden und diese als Tragleisten für die Außenwandbekleidung zu verwenden. Damit jedoch diese Tragleisten die erforderliche Druckfestigkeit aufweisen, werden sie so an die Gebäudewand angeklebt, daß die Mineralwollefasern im wesentlichen senkrecht zur Gebäudewand verlaufen. Da in üblichen Mineralwolleplatten die Fasern im wesentlichen parallel zur Plattenebene angeordnet sind, sägt man einen Streifen von einer Mineralwolleplatte ab und klebt diesen Streifen praktisch mit seiner einen Schnittfläche an die Gebäudewand an. Die Mineralwollefasern verlaufen dann im wesentlichen senkrecht zur Gebäudewand. Die Breite des abgeschnittenen Streifens entspricht dann der Höhe der Tragleiste, senkrecht zur Gebäudewand gemessen. Nachdem zwischen die beabstandeten Tragleisten Dämmstoffelemente angeordnet und mit der Gebäudewand verbunden worden sind, werden die Trägerplatten an die Außenflächen der Tragleisten angeklebt. Zusätzlich werden sie über Schrauben mit der Gebäudewand verbunden. Auf die Außenseite der Trägerplatten kann dann in bekannter Weise eine Putzbeschichtung, kleinformatiges Steinzeug, Keramik oder auch Natursteinplatten als Wetterschutzschicht und als dekorative Schicht angebracht werden. Eine derartige Außenwandbekleidung bewirkt durch die Verwendung von Mineralwollestreifen als Tragleisten und die darauf geklebte Trägerplatte eine immense Schallabtrennung, so daß die Schallrückhaltequote der erfindungsgemäßen Außenwandbekleidung gegenüber herkömmlichen mit den gleichen Dämmstoffelementen und den gleichen Trägerplatten um ca. 10 db steigt. Da Mineralwolleplatten ein verhältnismäßig billiges Baumaterial sind, können die Tragleisten aus diesem Baumaterial kostengünstig hergestellt werden. Auch der gesamte Montageaufwand ist verhältnismäßig gering und ermöglicht speziell Malern und Stukkateuren ohne aufwendige Unterkonstruktion die Montage der hinterlüfteten Außenwandbekleidung.The invention is therefore based on the idea of cutting off strips of mineral wool panels and using them as support strips for the outer wall cladding. However, so that these support strips have the required compressive strength, they are glued to the building wall in such a way that the mineral wool fibers essentially run perpendicular to the building wall. Since the fibers in conventional mineral wool panels are arranged essentially parallel to the plane of the panel, a strip is sawn off a mineral wool panel and this strip is practically glued to the building wall with its one cut surface. The mineral wool fibers then run essentially perpendicular to the building wall. The width of the cut strip then corresponds to the height of the support strip, measured perpendicular to the building wall. After insulating material elements have been arranged between the spaced support strips and connected to the building wall, the support plates are glued to the outer surfaces of the support strips. They are also connected to the building wall using screws. A plaster coating, small-sized stoneware, ceramic or natural stone slabs can then be applied in a known manner on the outside of the carrier plates as a weather protection layer and as a decorative layer. Such outer wall cladding causes the use of mineral wool strips as support strips and the carrier plate glued thereon an immense sound separation, so that the sound retention rate of the outer wall cladding according to the invention increases by about 10 db compared to conventional ones with the same insulating elements and the same carrier plates. Since mineral wool panels are a relatively cheap building material, the support strips can be produced inexpensively from this building material. The entire assembly effort is also relatively low and enables painters and plasterers in particular to install the ventilated outer wall cladding without complex substructure.

In der Zeichnung ist mit 1 die zu verkleidende Gebäudewand bezeichnet. An dieser Gebäudewand werden Tragleisten 2 mit ihren Innenseiten 2a angeklebt. Die Tragleisten 2 sind aus Mineralwolleplatten 2' gefertigt, wie es in Figur 2 dargestellt ist. Zweckmäßig werden Mineralwolleplatten mit einer Dichte von etwa 120 bis 150 kg/m3 verwendet. Die Dicke D kann vorzugsweise 100 mm betragen. Bei derartigen Mineralwolleplatten erstrecken sich die mit Strichen schematisch angedeuteten Mineralwollefasern 3 im wesentlichen parallel zur Plattenebene. Von einer derartigen Mineralwolleplatte 2' werden schmale Streifen mit einer Breite bzw. Höhe h durch Sägen abgetrennt. Die Breite h entspricht der gewünschten Höhe h der Tragleisten 2. Eine der Schnittflächen der abgeschnittenen Streifen bildet jeweils die Innenseite 2a der Tragleiste, die andere deren spätere Außenseite 2b. Die Tragleisten 2 werden in einem Achsabstand A von beispielsweise 600 mm vertikal verlaufend an die Gebäudewand 1 geklebt. Zwischen die Tragleisten 2 werden fassadengerechte Dämmstoffelemente 4 eingebaut und mittels Dämmstoffhaltern 5 gesichert. Als Dämmstoffelemente werden zweckmäßig Mineralwolleplatten oder -matten verwendet. Anstelle dieses Materials kann auch eine Hartschaumplatte als Dämmstoffelement 4 vorgesehen sein.In the drawing, 1 denotes the building wall to be clad. Support strips 2 with their inner sides 2a are glued to this building wall. The support strips 2 are made of mineral wool panels 2 ', as shown in Figure 2. Mineral wool panels with a density of approximately 120 to 150 kg / m 3 are expediently used. The thickness D can preferably be 100 mm. In such mineral wool panels, the mineral wool fibers 3 schematically indicated by lines extend essentially parallel to the panel plane. Narrow strips with a width or height h are separated from such a mineral wool plate 2 'by sawing. The width h corresponds to the desired height h of the support strips 2. One of the cut surfaces of the cut strips forms the inside 2a of the support strip, the other the later outside 2b thereof. The support strips 2 are glued to the building wall 1 in a vertical distance A of, for example, 600 mm. Between the support strips 2 facade-appropriate insulation elements 4 are installed and secured by means of insulation holders 5. As insulation elements Mineral wool sheets or mats are used appropriately. Instead of this material, a hard foam panel can also be provided as the insulation element 4.

Die Höhe h der Tragleisten 2, senkrecht zur Gebäudewand 1 gemessen, muß um mindestens 20 mm größer sein als die Dicke d der Dämmstoffelemente 4. Dies ist erforderlich, damit zwischen der Außenseite der Dämmstoffelemente 4 und der Innenseite der Trägerplatte 6 ein Luftspalt 7 von mindestens 20 mm Breite b entsteht.The height h of the support strips 2, measured perpendicular to the building wall 1, must be at least 20 mm greater than the thickness d of the insulating elements 4. This is necessary so that an air gap 7 of at least between the outside of the insulating elements 4 and the inside of the carrier plate 6 20 mm width b arises.

Die Trägerplatte 6 wird auf die Außenseiten 2b der Tragleisten 2 aufgeklebt. Als Kleber werden zweckmäßig hochwertige Bau- oder Fliesenkleber verwendet. Zusätzlich werden die Trägerplatten 6, deren Breite in horizontaler Richtung einem Vielfachen des Achsabstandes A entspricht, zweckmäßig unter Verwendung sogenannter Rahmendübel 8, die sich durch die Tragleisten 2 hindurch bis in die Gebäudewand 1 erstrecken, gesichert. Bei solchen Rahmendübeln (Hersteller: fischerwerke Artur Fischer GmbH & Co. KG, 72178 Waldachtal, handelt es sich um Kunststoffdübel, die ein in eine Bohrung 10 in der Gebäudewand 1 eingreifendes Halteteil 8a und einen sich durch die ganze Tragleiste 2 hindurch erstreckenden, mit einer Längsbohrung versehenen Schaft 2b aufweisen. In diese sogenannte Dübelhülse 8 wird eine Spezialschraube 11 eingeschraubt, die sich durch die Trägerplatte 6, den Schaft 8b und das Halteteil 8a hindurch erstreckt. Die Länge dieser Spezialschraube beträgt um 5 mm mehr als die Länge des Rahmendübels 8 zuzüglich der Dicke der Trägerplatte 6. Die Spezialschraube 11 besteht aus rostfreiem Stahl, ebenso wie die großflächige Unterlegscheibe 12.The carrier plate 6 is glued to the outer sides 2b of the support strips 2. High-quality construction or tile adhesives are expediently used as adhesives. In addition, the support plates 6, the width of which corresponds in the horizontal direction to a multiple of the center distance A, are expediently secured using so-called frame dowels 8, which extend through the support strips 2 and into the building wall 1. Such frame anchors (manufacturer: fischerwerke Artur Fischer GmbH & Co. KG, 72178 Waldachtal, Germany) are plastic dowels which have a holding part 8a which engages in a bore 10 in the building wall 1 and which extends through the entire support bar 2, with a A special screw 11, which extends through the carrier plate 6, the shaft 8b and the holding part 8a, is screwed into this so-called dowel sleeve 8. The length of this special screw is 5 mm more than the length of the frame plug 8 plus the thickness of the carrier plate 6. The special screw 11 is made of stainless steel, as is the large-area washer 12.

Auf die so vorbereitete Außenwandverkleidung wird außen auf die Trägerplatte 6 die strichpunktiert dargestellte Wetterschutzschicht oder Dekorschicht 13 aufgebracht. Dies kann z.B. eine Putzbeschichtung sein. Man kann jedoch auch auf den Trägerplatten kleinformatiges Steinzeug, Keramik oder Natursteinplatten mittels entsprechender Kleber befestigen.The weather protection layer or decorative layer 13 shown in broken lines is applied to the outside of the outer wall cladding prepared in this way on the carrier plate 6. This can e.g. be a plaster coating. However, small-sized stoneware, ceramics or natural stone slabs can also be attached to the carrier plates using appropriate adhesives.

Als Trägerplatte 6 wird zweckmäßig eine aus mit einem geschäumten organischen Bindemittel gebundenem Blähglasgranulat bestehende Platte verwendet, die zweckmäßig beidseitig mit Glasfasergewebe armiert ist. Derartige Trägerplatten werden unter dem Namen "Sto-Verotec-Trägerplatte" von der Firma Sto AG, D-79780 Stühlingen, vertrieben. Das Verfahren zur Herstellung derartiger Trägerplatten, zu deren Herstellung aus Altglas gewonnenes Blähglas verwendet wird, ist in der EP 290 881 A2 näher beschrieben. Trägerplatten der vorgeschlagenen Art haben ein verhältnismäßig geringes Gewicht und sind trotz ihres geringen Gewichtes sehr stabil, unbrennbar, dauerhaft, wasserfest und überhaupt unempfindlich gegen Umwelteinflüsse.A plate made of expanded glass granulate bound with a foamed organic binder is expediently used as the carrier plate 6, which plate is expediently reinforced on both sides with glass fiber fabric. Such carrier plates are sold under the name "Sto-Verotec carrier plate" by Sto AG, D-79780 Stühlingen. The process for the production of such carrier plates, for the production of which expanded glass obtained from waste glass is used, is described in more detail in EP 290 881 A2. Carrier plates of the proposed type have a relatively low weight and, despite their low weight, are very stable, non-flammable, durable, waterproof and generally insensitive to environmental influences.
