Description

Die Erfindung betrifft ein Wärmedämmverbundsystem zur Wärmedämmung einer Wand eines Gebäudes, mit wenigstens einer, vorzugsweise aus Fasermaterialen bestehenden Dämmplatte, die zwei zueinander beabstandete große Oberflächen und eine zwischen den großen Oberflächen umlaufende Nut aufweist, mit wenigstens einer an der Wand befestigbaren Halteschiene und mit wenigstens einer Verbindungsschiene, wobei die Halteschiene und die Verbindungsschiene in die umlaufende Nut greifen, wobei die Verbindungsschiene zwischen der Dämmplatte und einer benachbarten Dämmplatte angeordnet ist und sich an der Wand und/oder an der Halteschiene abstützt. Die Erfindung betrifft des Weiteren eine Dämmplatte, die im Wärmedämmverbundsystem verwendet werden kann.The invention relates to a thermal insulation composite system for thermal insulation a wall of a building, with at least one, preferably made of fiber materials existing insulation board, the two spaced apart large Having surfaces and a circumferential groove between the large surfaces, with at least one attachable to the wall holding rail and with at least one connecting rail, wherein the retaining rail and the connecting rail engage in the circumferential groove, the connecting rail is arranged between the insulation board and an adjacent insulation board and is supported on the wall and / or on the retaining rail. The invention further relates to an insulation board, which in the thermal insulation composite system can be used.

Ein derartiges Wärmedämmverbundsystem, wie es beispielsweise aus der DE 82 29 096 U1 bekannt ist, wird bevorzugt bei unebenen Wandflächen verwendet. Zum Anbringen des Wärmedämmverbundsystems werden die in der Regel horizontal verlaufenden Halteschienen an der Wand befestigt, wobei durch Abstandshalter zwischen Halteschiene und Wand die gegebenen Unebenheiten ausgeglichen werden. Die Dämmplatten werden Reihe für Reihe fugenversetzt befestigt. In den vertikalen Nuten zwischen den Dämmplatten jeweils einer Reihe werden die Federn der Verbindungsschienen eingeschoben. Wenn die aus den Dämmplatten gebildete Dämmschicht an angrenzende Bauteile stößt und die Dämmplatten abgeschnitten werden müssen, kann die Befestigung einer Dämmplatte auch durch senkrechte Halteschienen erfolgen.Such a thermal insulation composite system, as for example from the DE 82 29 096 U1 is preferably used in uneven wall surfaces. For attaching the thermal insulation composite system in the Usually horizontally extending retaining rails attached to the wall, wherein by spacers between retaining rail and wall the given bumps be compensated. The insulation boards become row by row attached offset to the joints. In the vertical grooves between the insulation boards one row each, the springs of the connecting rails are inserted. If the insulating layer formed from the insulation boards to adjacent components butts and the insulation boards must be cut off, the Fixing an insulation board also done by vertical support rails.

Eine Verbindungsschiene zwischen zwei Dämmplatten stützt sich an einer Halteschiene und/oder an der Wand ab. Dies erhöht die Standsicherheit gegen Wandsog und auch den Widerstand des Wärmedämmverbundsystems gegen Druckbeanspruchungen.A connecting rail between two insulation boards is supported on one Retaining rail and / or on the wall. This increases the stability against Wandsog and also the resistance of the thermal insulation composite system against Compressive stresses.

Übliche Plattenformate bei Polystyrol-Hartschaumplatten sind 50 cm mal 50 cm bei Dicken über 40 mm für die Wandfläche beziehungsweise 20 oder 30 mm für Fenster- oder Türlaibungen. Mineralwoll-Dämmplatten weisen handelsüblich das Format 80 cm mal 62,5 cm und für die Anwendung in der Fläche eine Mindestdicke von 5 cm auf.Typical plate formats in polystyrene foam boards are 50 cm by 50 cm for thicknesses over 40 mm for the wall surface or 20 or 30 mm for Window or door reveals. Mineral wool insulation boards are commercially available the format 80 cm by 62.5 cm and for use in the area one Minimum thickness of 5 cm.

Die Halteschienen weisen zur Zeit handelsübliche Längen von ca. 2 m auf. Längere Schienen sind wegen der beengten Arbeitsräume auf den Standard-Gerüsten nicht praktikabel. Neuere Gerüstkonstruktionen weisen demgegenüber wesentlich mehr Freiraum auf. Um den Einbau der Dämmplatten zu beschleunigen, werden deren Längen von üblicherweise 800 mm bei Mineralwolle-Dämmplatten auf ca. 1,5 bis 3 m, vorzugsweise 2 m, vergrößert. Mit größerer Länge sind die Dämmplatten in sich steifer, gleichzeitig wird die Zahl der Versprünge und Fugen zwischen den Dämmplatten verringert. Die Oberfläche der Dämmschicht wird ebener, was die nachfolgende Beschichtung der Dämmplatten wesentlich vereinfacht.The support rails currently have commercial lengths of about 2 m. Longer rails are due to the cramped work spaces on the standard scaffolding not practicable. In contrast, newer scaffolding constructions have much more freedom. To accelerate the installation of the insulation boards, their lengths are usually 800 mm for mineral wool insulation boards to about 1.5 to 3 m, preferably 2 m, increased. With bigger ones Length, the insulation boards are stiffer in itself, at the same time the number of Reduced cracks and joints between the insulation boards. The surface the insulating layer is level, which is the subsequent coating of the insulation boards considerably simplified.

Durch den Einsatz längerer Dämmplatten verringert sich die Anzahl der Verbindungsschienen des Wärmedämmverbundsystems, die zwischen zwei Dämmplatten geschoben werden. Während im Hinblick auf die Standsicherheit gegenüber Windsog eine Verringerung der Anzahl der Verbindungsschienen unkritisch sein dürfte, kann durch die verringerte Anzahl von Verbindungsschienen der Widerstand des Wärmedämmverbundsystems gegenüber Druckbeanspruchungen zu sehr beeinträchtigt werden.The use of longer insulation boards reduces the number of connecting rails the thermal insulation composite system between two insulation boards be pushed. While faced with regard to stability Windsog a reduction in the number of connecting rails may be uncritical, due to the reduced number of connecting rails the resistance of the thermal insulation composite system to compressive stresses too much affected.

Dämmplatten für Wärmedämmverbundsysteme mit umlaufenden Nuten sind aus der DE 200 11 332 U1 bekannt. Der Erfindung liegt daher die Aufgabe zugrunde, ein Wärmedämmverbundsystem bzw. eine Dämmplatte hierfür bereitzustellen, das bzw. die trotz des Einsatzes vergleichsweise langer Dämmplatten einen genügend hohen Widerstand gegen Druckbeanspruchungen aufweist. Insulating boards for external thermal insulation systems with circumferential grooves are known from DE 200 11 332 U1. The invention is therefore the task to provide a thermal insulation composite system or an insulation board therefor, the one or the despite the use of comparatively long insulation boards a sufficiently high resistance to compressive stresses having.

Der Aufgabe wird durch eine zusätzliche Schiene gelöst, wobei die Dämmplatte auf der wandseitigen großen Oberfläche wenigstens eine Ausnehmung zum Eingriff der zusätzlichen Schiene aufweist, die sich an der Wand und/oder an der Halteschiene abstützt. Durch eine oder mehrere nebeneinander angeordnete Ausnehmungen in Verbindung mit den zusätzlichen Schienen kann der Widerstand gegen Druckbelastung trotz großer Länge der Dämmplatte entsprechend beeinflusst werden. Somit können die mit dem Einsatz längerer Dämmplatten einhergehenden Vorteile wie schnellerer Einbau der Dämmplatten und geringere Anzahl von Versprüngen und Fugen ohne Beeinträchtigung des Widerstands gegen Druckbeanspruchungen ausgenutzt werden.The task is solved by an additional rail, the insulation board on the wall-side large surface at least one recess for Has engagement of the additional rail, which is located on the wall and / or at the support rail is supported. By one or more juxtaposed Recesses in conjunction with the additional rails can be the resistance In spite of the great length of the insulation board, it is influenced accordingly against pressure become. Thus, the associated with the use of longer insulation boards Advantages such as faster installation of the insulation boards and lower Number of breaks and joints without affecting the resistance be exploited against compressive stresses.

Vorzugsweise weist die zusätzliche Schiene ein gleiches Profil wie die Verbindungsschiene auf. Somit kann eine bereits vorhandene Verbindungsschiene als zusätzliche Schiene mit der Ausnehmung auf der wandseitigen großen Oberfläche der Dämmplatte in Eingriff gebracht werden. Dies reduziert die Anzahl verschiedener Teile des Wärmedämmverbundsystems und vereinfacht den Aufbau.Preferably, the additional rail has the same profile as the connecting rail on. Thus, an existing connection rail as additional rail with the recess on the wall-side large surface the insulating board are brought into engagement. This reduces the number various parts of the thermal insulation composite system and simplifies the Construction.

In einer bevorzugten Ausführungsform erstreckt sich die Ausnehmung quer zur Längsachse der Dämmplatte. Da die Längsachse der Dämmplatte im Wärmedämmverbundsystem in der Regel horizontal verläuft, erstreckt sich die zusätzliche Schiene in vertikaler Richtung. Die an den vertikalen Seitenflächen angeordneten Verbindungsschienen und die zusätzliche Schiene verlaufen daher parallel zueinander. Dadurch kann die zusätzliche Schiene sich wie die Verbindungsschiene in gleicher Weise an den horizontal verlaufenden Halteschienen abstützten.In a preferred embodiment, the recess extends transversely to the Longitudinal axis of the insulation board. As the longitudinal axis of the insulation board in the thermal insulation composite system usually runs horizontally, the additional extends Rail in the vertical direction. The arranged on the vertical side surfaces Connecting rails and the additional rail therefore run parallel to each other. This allows the additional rail to be like the connecting rail in the same way on the horizontally extending support rails abstützten.

Wenn die Dämmplatte nur eine Ausnehmung aufweist, verläuft diese vorzugsweise in der Mitte der wandseitigen großen Oberfläche. Durch diese Positionierung der Ausnehmung verteilt sich eine Druckbelastung der Dämmplatte optimal auf die zusätzliche Schiene und auf die beiden an den Rändern der Dämmplatten angeordneten Verbindungsschienen.If the insulation board has only one recess, this runs preferably in the middle of the wall-side large surface. Through this positioning the recess distributes a pressure load of the insulation board optimally on the additional rail and on the two at the edges of the Insulation boards arranged connecting rails.

Bei mehreren Ausnehmungen können diese im gleichen Abstand zueinander an der wandseitigen Oberfläche der Dämmplatte angebracht sein. Vorleilhafterweise teilen die Ausnehmungen die wandseitige Oberfläche der Dämmplatte in gleichgroße Bereiche, so dass die Abstände zwischen zwei zusätzlichen Schienen und zwischen einer Verbindungsschiene am Rand der Dämmplatte und einer zusätzlichen Schiene gleichgroß sind.With several recesses they can be at the same distance from each other be attached to the wall-side surface of the insulation board. Vorleilhafterweise The recesses divide the wall-side surface of the insulation board equal areas, so that the distances between two additional rails and between a connecting rail at the edge of the insulating board and an additional rail are the same size.

In einer bevorzugten Ausführungsform ist bei der Ausnehmung eine Hinterschneidung vorgesehen, wobei die zusätzliche Schiene mit einem Vorsprung oder mehreren Vorsprüngen die Ausnehmung hintergreift. In diesem Fall wird die Schiene durch Verschieben entlang der Ausnehmung in die Ausnehmung eingeführt. Die zusätzliche Schiene kann zum Aufbau des Wärmedämmverbundsystems auf der Baustelle oder werkseitig in die Ausnehmung geschoben werden.In a preferred embodiment, the recess is an undercut provided, with the additional rail with a projection or a plurality of projections engages behind the recess. In this case will the rail by moving along the recess in the recess introduced. The additional rail can be used to construct the thermal insulation composite system at the construction site or pushed into the recess at the factory become.

Die Verbindungsschiene kann ein T-förmiges Profil aufweisen. Im Wärmeverbundsystem greift ein erster Quersteg des T-Profils in die umlaufende Nut einer ersten Dämmplatte, und ein zweiter Quersteg des T-Profils greift in die umlaufende Nut einer zweiten Dämmplatte, die im Wärmedämmverbundsystem an der ersten Dämmplatte anliegt. Ein zu den Querstegen senkrechter Hauptsteg des T-Profils erstreckt sich in Richtung der Wand. Die Steghöhe des Hauptstegs ist vorzugsweise auf den Abstand der umlaufenden Nut der Dämmplatte von der wandseitigen großen Oberfläche der Dämmplatte abgestimmt.The connecting rail may have a T-shaped profile. In the thermal composite system engages a first crosspiece of the T-profile in the circumferential groove of a first insulation board, and a second crosspiece of the T-profile engages in the circumferential Groove a second insulation board, in the thermal insulation composite system the first insulation board rests. A main web perpendicular to the transverse webs of the T-profile extends towards the wall. The bridge height of the main bridge is preferably to the distance of the circumferential groove of the insulation board matched by the wall-side large surface of the insulation board.

Die Ausnehmung ist vorteilhafterweise als Nut mit einem T-förmigen Querschnitt ausgebildet. Diese Ausnehmung nimmt eine Schiene mit korrespondierendem T-Profil auf, wobei ein Hauptsteg des T-Profils in Richtung der Wand zeigt.The recess is advantageously a groove with a T-shaped cross-section educated. This recess takes a rail with corresponding T-profile on, with a main web of the T-profile towards the wall shows.

Die Halteschiene kann ein T-förmiges Profil aufweisen, wobei ein Quersteg des T-Profils in die horizontal verlaufende Nut einer ersten Dämmplatte greift, und ein zweiter Quersteg in die horizontal verlaufende Nut einer über der ersten Dämmplatte angeordneten zweiten Dämmplatte greift. Um die Halteschiene an der Wand zu befestigen, kann ein Bereich eines Hauptstegs des T-Profils abgewinkelt sein. Der abgewinkelte Bereich des Hauptstegs liegt im wesentlichen an der Wand an und kann durch geeignete Befestigungsmittel an dieser befes-Wand lassen sich Abstandshalter anordnen, die auch bei unebener Wand eine parallele Ausrichtung der Halteschienen in einer Ebene ermöglichen.The retaining rail may have a T-shaped profile, wherein a crosspiece of the T-profile engages in the horizontal groove of a first insulation board, and a second crosspiece in the horizontally extending groove one above the first Insulation board arranged second insulation board attacks. To the holding rail To fix the wall, an area of a main web of the T-profile angled be. The angled portion of the main web is essentially on the wall and can be fastened to this wall by suitable fasteners Spacers can be arranged, even on uneven walls allow parallel alignment of the support rails in one plane.

Die Ausnehmung kann sich über die gesamte Breite der Dämmplatte erstrecken. Somit lässt sich eine Schiene von beiden Seitenrändern der Dämmplatte in die Ausnehmung schieben. Außerdem kann dadurch die Dämmplatte über ihre gesamte Breite eine Abstützung durch eine in der Ausnehmung greifende Schiene erfahren, soweit die Schiene sich über die gesamte Länge der Ausnehmung erstreckt.The recess may extend over the entire width of the insulation board. Thus, a rail can be from both side edges of the insulation board push into the recess. In addition, thereby the insulation board over their entire width a support by a cross in the recess Rail experienced as far as the rail is over the entire length of the recess extends.

Bei einer bevorzugten Ausführungsform sind an den beiden Enden der Verbindungsschiene beziehungsweise der zusätzlichen Schiene die Querstege weggeschnitten. Dadurch lässt sich die Verbindungsschiene mit dem an beiden Enden überstehenden Hauptsteg jeweils unter die Querstege der Halteschiene schieben, auf die die Verbindungsschiene senkrecht stößt. Dies gewährleistet eine gewisse Kraftschlüssigkeit zwischen Verbindungsschiene und Halteschiene.In a preferred embodiment, at the two ends of the connecting rail or the additional rail cut away the transverse webs. This allows the connecting rail with the at both Ends projecting main bar respectively below the transverse webs of the retaining rail push on which the connecting rail abuts perpendicularly. This ensures a certain force fit between the connecting rail and retaining rail.

Anstelle einer Dämmplatte mit weitgehend gleichmäßig hoher Rohdichte kann die Dämmplatte eine wandseitig verdichtete Oberflächenzone aufweisen, wobei die umlaufende Nut und die Ausnehmung in oder direkt oberhalb der verdichteten Schicht liegen. Durch eine derart verdichtete Zone weist die Dämmplatte im dem Bereich, in dem die Halte- und Verbindungsschienen in Eingriff kommen, eine größere Festigkeit auf.Instead of an insulating board with largely uniformly high density can the insulation board have a wall-side compacted surface zone, wherein the circumferential groove and the recess in or directly above the compacted Layer lie. By such a compressed zone, the insulation board in the the area in which the holding and connecting rails engage, greater strength.

Die Erfindung betrifft auch eine vorzugsweise aus Mineralwolle bestehende Dämmplatte, die in einem der oben beschriebenen Ausführungsbeispiele für das erfindungsgemäße Wärmedämmverbundsystem eingesetzt werden kann. Die Dämmplatte umfasst zwei zueinander beabstandete große Oberflächen, die über Seitenflächen miteinander verbunden sind, und eine auf den Seitenflächen umlaufende Nut. Die Dämmplatte zeichnet sich dadurch aus, dass in einer großen Oberfläche der Dämmplatte wenigstens eine Ausnehmung zur Aufnahme einer Schiene vorgesehen ist, wobei die Ausnehmung wenigstens eine Hinterschneidung aufweist, in die die Schiene mit einem Vorsprung oder mehreren Vorsprüngen eingreift. The invention also relates to a preferably made of mineral wool Insulating board, which in one of the embodiments described above the thermal insulation composite system according to the invention can be used. The insulation board comprises two spaced-apart large surfaces, the are connected by side surfaces, and one on the side surfaces circumferential groove. The insulation board is characterized by the fact that in one large surface of the insulation board at least one recess for receiving a rail is provided, wherein the recess at least one Undercut has, in which the rail with a projection or more Protrusions intervenes.

Vorzugsweise sind zwei Seitenflächen der Dämmplatte planparallel zueinander ausgebildet, wobei der Abstand der beiden Seitenflächen zueinander um weniger als 0,5 mm variiert. Alternativ oder zusätzlich sind zwei aneinander stoßende Seitenflächen im rechten Winkel angeordnet, wobei die Schiefwinkeligkeit dieser beiden Seitenflächen weniger als 1 mm bezogen auf die Länge eines Meters beträgt. Durch diese über die für Mineralwolle-Dämmplatten einschlägige Norm (DIN 18165-1) hinausgehenden Toleranzen können die Dämmplatten im Wärmedämmverbundsystem nahezu ohne Fugen neben- und übereinander angeordnet werden. So werden in der Dämmschicht zum einen Wärmebrücken effektiv vermieden. Zum anderen kann beim Wärmedämmverbundsystem ein auf die Dämmplatten aufzutragender Putz nicht in die Fugen eingedrückt werden. Hierdurch können Risse im Putz vermieden werden, welche entstehen könnten, wenn aufgrund der abrupten Dickenänderung und der Verklammerung in den Fugen die Putzbewegungen beim Schwinden oder Quellen nach Feuchtaufnahme behindert werden.Preferably, two side surfaces of the insulation board are plane-parallel to each other formed, wherein the distance between the two side surfaces to each other by less varies as 0.5 mm. Alternatively or additionally, two abutting ones Side surfaces arranged at right angles, with the oblique angle These two side surfaces less than 1 mm in relation to the length of a Meters is. Through this over the relevant for mineral wool insulation boards Standard (DIN 18165-1) beyond tolerances, the insulation boards in the thermal insulation composite system with virtually no joints next to and above each other to be ordered. Thus, in the insulating layer on the one hand thermal bridges effectively avoided. On the other hand, in the thermal insulation composite system plaster to be applied to the insulation boards should not be pressed into the joints. As a result, cracks in the plaster can be avoided, which arise could, if due to the abrupt change in thickness and the stapling in the joints, the cleaning movements during shrinkage or swelling after moisture absorption be hampered.

Die Dickentoleranz soll vorzugsweise kleiner als 0,5 mm sein. Somit lassen sich die Dämmstoffplatten gut in einem Wärmedämmverbundsystem einsetzen, bei denen auf die Dämmplatten eine sogenannte Dünnschutzschicht mit minimaler Dicke von ca. 1,5 bis 3 mm aufgetragen wird. Insbesondere bei sehr kleinen beziehungsweise nicht vorhandenen Fugen können sehr geringe Unterschiede in der Putzdicke über der Dämmschichtoberfläche realisiert werden. So lassen sich die auf große Unterschiede in der Putzdicke zurückzuführenden Erscheinungsbilder wie wolkig erscheinende Fleckenbildungen nach Regenbeaufschlagung oder bei dem Austrocknen des Putzes vermeiden.The thickness tolerance should preferably be less than 0.5 mm. Thus can be use the insulation boards well in a thermal insulation composite system, at which on the insulation boards a so-called thin protective layer with minimal Thickness of about 1.5 to 3 mm is applied. Especially with very small ones or not existing joints can be very small differences be realized in the plaster thickness over the Dämmschichtoberfläche. Let it be the appearance due to large differences in plaster thickness Like cloudy stains after rain or avoid drying out the plaster.

Zumindest eine Seitenfläche der Dämmplatte kann eine kompressible Zone aufweisen, die beispielsweise durch gezielte mehrmalige Kompression und Dekompression elastifiziert wurde. Vorzugsweise ist die Zone der Seitenfläche elastifiziert, die in Einbaulage der Dämmplatte im Wärmedämmverbundsystem an einem Hauptsteg einer Verbindungs- oder Halteschiene anliegt. Damit können trotz des zwischen zwei benachbarten Dämmplatten angeordneten Hauptstegs die beiden Dämmplatten an der vom Hauptsteg angewandten großen Oberfläche ohne Fuge oder Spalt aneinander anliegen.At least one side surface of the insulation board can be a compressible zone have, for example, by targeted repeated compression and Decompression was elasticized. Preferably, the zone is the side surface elasticized, in the installation position of the insulation board in the thermal insulation composite system abuts a main web of a connecting or retaining rail. With that you can despite the arranged between two adjacent insulation boards main ridge the two insulating boards on the large bridge used by the main bridge Surface without gap or gap abut each other.

Es sei darauf hingewiesen, dass auch bei Verwendung von Dämmplatten ohne die erfindungsgemäße Ausnehmung an einer großen Oberfläche die Merkmale hinsichtlich planparalleler Seitenflächen, der Schiefwinkeligkeit, der Dickentoleranz und/oder der kompressiblen Zonen zu einer vorteilhaften Dämmschicht mit wenig Versprüngen, Fugen oder Unebenheiten führt.It should be noted that even when using insulation boards without the recess according to the invention on a large surface the features with regard to plane-parallel side surfaces, the oblique angle, the thickness tolerance and / or the compressible zones to an advantageous insulating layer leads little jumps, joints or bumps.
