Beispielsweise offenbart die DE 198 15 170 A1 ein Dämmstoffelement zu Wärme- und/oder Schalldämmzwecken, insbesondere in Verbindung mit Wärmedämmverbundsystemen, bestehend aus einer Wärmedämmplatte, insbesondere aus Mineralfasern, vorzugsweise aus Glas- oder Steinwollefasern oder Polystyrol-Hartschaum, mit einer zumindest auf einer großen Oberfläche aufgebrachten Beschichtung zur zumindest partiellen Verklebung der Wärmedämmplatte mit Deckschichten bzw. tragenden Flächen. Dieses Dämmstoffelement zeichnet sich dadurch aus, daß die Wärmedämmplatte zumindest im Bereich der die Beschichtung aufweisenden großen Oberfläche bzw. Oberflächen perforiert ausgebildet ist und eine Vielzahl von zur Beschichtung hin offenen Löchern aufweist und daß die Beschichtung Vorsprünge ausbildet, die in die Löcher eingreifen, so daß die ausgehärtete Beschichtung eine nagelförmige, in der Wärmedämmplatte verankerte Struktur hat. Derartige Dämmstoffelemente haben sich im wesentlichen bewährt.Such insulation elements are known from the prior art. For example, DE 198 15 170 A1 discloses an insulation element Heat and / or sound insulation purposes, especially in connection with Thermal insulation composite systems, consisting of a thermal insulation board, in particular from mineral fibers, preferably from glass or rock wool fibers or rigid polystyrene foam, with one at least on one large surface applied coating for at least partial Bonding the thermal insulation board with cover layers or load-bearing Surfaces. This insulation element is characterized in that the Thermal insulation board at least in the area of the coating large surface or surfaces is perforated and has a plurality of holes open to the coating and that the coating forms protrusions which engage in the holes, so that the cured coating is a nail-shaped, in the thermal insulation board anchored structure. Such insulation elements have has essentially proven itself.
Darüber hinaus ist aus der EP 0 758 704 A1 eine bei Gebäuden für Dächer, Wände und Decken verwendbare Schalldämmplatte bekannt, die aus einer aus Schälldämmmaterial bestehenden Schalldämmlage besteht.In addition, EP 0 758 704 A1 describes one for buildings for roofs, Walls and ceilings usable soundproofing board known consists of a sound insulation layer consisting of peeling material.
Beiderseits der Schalldämmlage ist jeweils eine an die Schalldämmlage angeschäumte Hartschaumstofflage angeordnet. Zu diesem Zweck wird die Schalldämmlage zumindest einseitig in gleichmäßigem Abstand mit quer zur Längserstreckung verlaufenden Nuten versehen, bevor die Schalldämmlage auf die erst anschließend aushärtende Hartschaumstofflage gedrückt wird. Hierbei bildet die Hartschaumstofflage Vorsprünge aus, die in die quer verlaufenden Nuten eingreifen.On both sides of the sound insulation layer is one to the sound insulation layer foamed rigid foam layer arranged. For this purpose the sound insulation layer at least on one side with an even distance Grooves running transversely to the longitudinal extension before the Soundproofing layer on the hard foam layer that only hardens afterwards is pressed. The rigid foam layer forms protrusions which engage in the transverse grooves.
Weiterhin ist aus der DE-OS 2104660 ein vorgefertigtes selbsttragendes schall- und wärmedämmendes Verbundelement bekannt. Dieses Verbundelement besteht aus einer Mineralfaserplatte, die beidseitig kegelförmige Ausnehmungen aufweist, in die CaSO4-Bindebaustoffe in flüssigem Zustand eindringen, so daß eine intensive Verdübelung der dadurch gebildeten Oberflächenbeschichtung mit der Mineralfaserplatte entsteht. Nach Aushärten des Bindebaustoffes wird somit ein sandwichartiges Element ausgebildet.Furthermore, a prefabricated self-supporting sound and heat insulating composite element is known from DE-OS 2104660. This composite element consists of a mineral fiber board, which has conical recesses on both sides, into which CaSO 4 binding materials penetrate in the liquid state, so that an intensive dowelling of the surface coating thus formed with the mineral fiber board is created. After the binding material has hardened, a sandwich-like element is thus formed.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Dämmstoffelement derart weiterzuentwickeln, daß eine verbesserte Verbindung zwischen der Deckschicht und der Mineralfaserplatte erzielt wird.Based on this prior art, the invention has for its object to further develop an insulating element such that an improved connection between the cover layer and the mineral fiber board is achieved.
Die Lösung dieser Aufgabenstellung sieht vor, daß die Mineralfaserplatte im Bereich unterhalb der Deckschicht eine Faserschicht aufweist, die in einer Richtung parallel zur großen Oberfläche der Mineralfaserplatte druckfest ist und daß die Mineralfaserplatte im Bereich unterhalb dieser Faserschicht ein Faserverlauf aufweist, der rechtwinklig zur großen Oberfläche der Mineralfaserplatte druckfest ist, wobei die Ausnehmungen durch die Faserschicht hindurch bis in den Bereich des rechtwinklig zur großen Oberfläche ausgerichteten Faserverlaufs reichen.The solution to this problem provides that the mineral fiber plate in the area below the cover layer has a fiber layer that is pressure-resistant in a direction parallel to the large surface of the mineral fiber plate and that the mineral fiber plate has a fiber course in the area below this fiber layer that is perpendicular to the large surface of the Mineral fiber board is pressure-resistant, the recesses extending through the fiber layer into the area of the fiber course oriented at right angles to the large surface.
Bei einem erfindungsgemäß ausgebildeten Dämmstoffelement hat es sich als vorteilhaft erwiesen, daß das im wesentlichen flüssig oder zähflüssig aufzutragende und auszuhärtende Material vollständig in die Ausnehmungen eindringen kann, wobei durch den auflastenden Druck der Deckschicht das Material unterhalb der parallel zu den großen Oberflächen druckfesten Faserschicht die dort befindlichen, rechtwinklig zu den großen Oberflächen ausgerichteten Fasern in begrenztem Maße parallel zu den großen Oberflächen verdrängen kann, so daß sich nach dem Aushärten der Deckschicht eine hinterschnittene Verankerung der Deckschicht in der Mineralfaserplatte ergibt. Hierbei ist von besonderer Bedeutung, daß die Druckfestigkeit der unterhalb der Deckschicht gelegenen Faserschicht größer ist, als die Druckfestigkeit des unterhalb der Faserschicht angeordneten Bereiches. Darüber hinaus erhält das Dämmstoffelement durch einen derartigen Faserverlauf insgesamt eine hohe Druckfestigkeit, die geeignet ist, auch hohe Lasten der Deckschicht zu tragen, ohne daß Beschädigungen und/oder Zerstörungen in der Mineralfaserplatte auftreten.In the case of an insulating element designed according to the invention, it has proven to be advantageous in that it is essentially liquid or viscous material to be applied and hardened completely into the recesses can penetrate, due to the pressure of the top layer the material below that parallel to the large surfaces pressure-resistant fiber layer there, at right angles to the big ones Limited aligned fibers parallel to the surface can displace large surfaces, so that after curing the underlayer an undercut anchoring of the top layer in the Mineral fiber board results. It is particularly important here that the Compressive strength of the fiber layer below the top layer is greater than the compressive strength of the arranged below the fiber layer Area. In addition, the insulation element gets through such a fiber course overall high compressive strength, the is suitable to bear high loads of the top layer without damage and / or destruction occurs in the mineral fiber board.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die Ausnehmungen hinterschnitten ausgebildet sind. Durch diese hinterschnittene Ausgestaltung der Ausnehmungen wird der Deckschicht bereits ein bestimmtes Volumen eingeräumt, das zu einer intensiven Verankerung der Deckschicht mit der Mineralfaserplatte geeignet ist. Vorzugsweise sind die Ausnehmungen V-förmig hinterschnitten ausgebildet, so daß sichergestellt ist, daß die Ausnehmungen vollständig ausgefüllt werden, ohne daß sich Hohlräume bilden, die hinsichtlich der Tragfähigkeit des Dämmstoffelementes bzw. seiner Wärmedämmeigenschaften bzw. Schalldämmeigenschaften nachteilig sind.According to a further feature of the invention it is provided that the Recesses are formed undercuts. Through this undercut The design of the recesses is already the top layer given a certain volume, which leads to an intensive anchoring the top layer with the mineral fiber board is suitable. Preferably the recesses are V-shaped undercut, so that it is ensured that the recesses are completely filled, without the formation of voids that with regard to the load-bearing capacity of the Insulation element or its thermal insulation properties or Soundproofing properties are disadvantageous.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Ausnehmungen unter einem Winkel schräg zur großen Oberfläche der Mineralfaserplatte ausgerichtet sind. Derartige Ausnehmungen lassen sich beispielsweise im kontinuierlichen Herstellungsprozeß derartiger Dämmelemente in einfacher und kostengünstiger Weise einarbeiten und bieten darüber hinaus eine ausreichend große Verbindungsfläche zwischen der Deckschicht und der Mineralfaserplatte.According to a further embodiment of the invention it is provided that the Recesses at an angle to the large surface of the Mineral fiber board are aligned. Such recesses can be for example in the continuous manufacturing process of such insulation elements incorporate and offer in a simple and cost-effective manner in addition, a sufficiently large connection area between the Top layer and the mineral fiber board.
Es ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß die Mineralfaserplatte aus einem aufgependelten Mineralfaservlies besteht. Hierbei wird in einem ersten Schritt ein Primärvlies in an sich bekannter Weise gebildet, wobei aus einer Sammelkammer abgezogene Mineralfasern auf einem Förderband abgelegt werden. Dieses Primärvlies hat einen parallel zu seinen großen Oberflächen ausgerichteten Faserverlauf. Durch Aufpendeln dieses Primärvlieses wird dieser Faserverlauf dahingehend im Sekundärvlies geändert, daß die einzelnen Fasern im Mittelbereich des Sekundärvlieses im wesentlichen rechtwinklig zu den großen Oberflächen ausgerichtet ist. Lediglich im Bereich der großen Oberflächen des Sekundärvlieses existiert weiterhin ein Faserverlauf parallel zu den großen Oberflächen, der noch durch zusätzliche Kompression des Sekundärvlieses auf die großen Oberflächen verstärkt werden kann, so daß sich insgesamt ein Dämmstoffelement ergibt, bei dem in einem dünnen Bereich unterhalb der großen Oberflächen die Fasern parallel zu den großen Oberflächen und in einem weitaus größeren Bereich unterhalb dieser parallel ausgerichteten Fasern ein Bereich mit rechtwinklig zu den großen Oberflächen ausgerichteten Fasern ergibt. Ein derartiges Mineralfaservlies ist insbesondere geeignet, für ein entsprechendes erfindungsgemäßes Dämmstoffelement Verwendung zu finden.It is provided according to a further feature of the invention that the Mineral fiber board consists of a suspended mineral fiber fleece. In a first step, a primary nonwoven is known Formed in such a way, with mineral fibers drawn off from a collecting chamber placed on a conveyor belt. This primary fleece has one fiber orientation aligned parallel to its large surfaces. By If this primary fleece is suspended, this fiber course is Secondary fleece changed that the individual fibers in the central area of the Secondary fleece essentially perpendicular to the large surfaces is aligned. Only in the area of the large surfaces of the secondary fleece there is still a fiber path parallel to the large surfaces, by additional compression of the secondary fleece can be reinforced on the large surfaces, so that overall an insulation element results in a thin area below the large surfaces the fibers parallel to the large surfaces and in a much larger area below this aligned in parallel Fibers an area perpendicular to the large surfaces aligned fibers results. Such a mineral fiber fleece is in particular suitable for a corresponding insulation element according to the invention To find use.
Es ist weiterhin vorgesehen, daß die Mineralfaserplatte an ihren gegenüberliegenden Schmalseiten korrespondierend ausgebildete Abstufungen aufweist. Ein derartig ausgebildetes Dämmstoffelement läßt sich problemlos zu einer im wesentlichen fugenlosen Wärmedämmung verarbeiten, da benachbarte Dämmstoffelemente sich mit einem bestimmten Bereich gegenseitig überlappen. Selbstverständlich besteht hier auch die Möglichkeit, entsprechende Abstufungen nicht nur an den Schmalseiten, sondern auch an den Längsseiten vorzusehen, so daß auch in diesen Bereichen eine Überlappung benachbarter Dämmstoffelemente besteht.It is also contemplated that the mineral fiber board at their opposite Correspondingly designed gradations on the narrow sides having. Such an insulating element can be easily process into essentially seamless thermal insulation, because neighboring insulation material elements deal with a certain area overlap each other. Of course there is also the Possibility of corresponding gradations not only on the narrow sides, but also to be provided on the long sides, so that even in these areas there is an overlap of adjacent insulation elements.
Schließlich ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß die Mineralfaserplatte an ihrer der Deckschicht gegenüberliegenden großen Oberfläche eine Kaschierung und/oder Beschichtung aufweist. Eine derartige Kaschierung und/oder Beschichtung dient zum einen der Erhöhung der Stabilität des Dämmstoffelementes insgesamt. Andererseits ermöglicht eine derartige Kaschierung die Anordnung mehrerer Dämmstofflamellen auf dergleichen, die anschließend mit einem Faservlies überdeckt werden, in dem die Fasern parallel zu den großen Oberflächen verlaufen, so daß nach Einbringen der entsprechenden Ausnehmungen ein erfindungsgemäßes Dämmstoffelement vorliegt. Die Ausnehmungen können als durchgehende Nuten im Dämmstoffelement ausgebildet sein. Alternativ besteht die Möglichkeit, daß entsprechende Ausnehmungen nur partiell bzw. punktuell in den großen Oberflächen des Dämmstoffelementes angeordnet sind.Finally, according to a further feature of the invention, that the mineral fiber board on the opposite of the top layer large surface has a lamination and / or coating. Such lamination and / or coating serves on the one hand Overall increase in the stability of the insulation element. On the other hand Such a lamination enables the arrangement of several insulating material lamellae on the like, which is then covered with a non-woven fabric are covered by making the fibers parallel to the large surfaces run so that after making the appropriate recesses there is an insulation element according to the invention. The recesses can be formed as continuous grooves in the insulation element. Alternatively, there is the possibility that corresponding recesses only partially or selectively in the large surfaces of the insulation element are arranged.

In Figur 1 ist ein Dämmstoffelement 1 dargestellt, das aus einer Mineralfaserplatte
2 besteht, die mit einer Deckschicht 3 aus Beton verbindbar ist.
Die Deckschicht 3 wird in flüssigem oder zähflüssigem Zustand auf eine
große Oberfläche 4 der Mineralfaserplatte 2 aufgetragen.In Figure 1, an
Die Mineralfaserplatte 2 besteht aus einer unmittelbar unterhalb der grossen
Oberfläche 4 angeordneten Faserschicht 5, bei der die einzelnen Fasern
eine Ausrichtung parallel zur großen Oberfläche 4 aufweist. Unterhalb
der Faserschicht 5 weist die Mineralfaserplatte 2 einen Abschnitt 6
auf, der aus Fasern besteht, welche im wesentlichen rechtwinklig zur grossen
Oberfläche 4 ausgerichtet sind. Die Faserschicht 5 ist fest mit dem
Abschnitt 6 verbunden.The
Durch die Ausrichtung der Fasern in der Faserschicht 5 ist die Faserschicht
5 in einer Richtung parallel zur großen Oberfläche 4 relativ druckfest
ausgebildet, wohingegen der Abschnitt 6 in gleicher Richtung eine
geringere Druckfestigkeit aufweist. Demgegenüber weist der Abschnitt 6
in einer Richtung rechtwinklig zu der großen Oberfläche 4 eine relativ große
Druckfestigkeit auf, die in jedem Fall größer ist, als die Druckfestigkeit
der Faserschicht 5 in gleicher Druckrichtung.Due to the alignment of the fibers in the
In der großen Oberfläche 4 sind zur Deckschicht 3 hin geöffnete Ausnehmungen
7 in der Mineralfaserplatte 2 angeordnet. Die Ausnehmungen 7
weisen gemäß Figur 1 einen rechtwinkligen Querschnitt auf und sind als
sich über die gesamte Breite der Mineralfaserplatte 2 erstreckenden Nuten
ausgebildet.In the
Wird die flüssige oder zähflüssige Deckschicht 3 auf die große Oberfläche
4 der Mineralfaserplatte 2 aufgetragen, so werden die Ausnehmungen 7
mit dem Material der Deckschicht 3 ausgefüllt. Aufgrund der auflastenden
Masse der Deckschicht 3 entsteht in den Ausnehmungen 7 ein Druck, der
zu einer Ausdehnung des in die Ausnehmungen 7 eingedrungenen Materials
der Deckschicht 3 in Richtung der Pfeile 8 gemäß Figur 1 führt. Durch
die Faserorientierung in der Faserschicht 5 und dem Abschnitt 6 bildet
das in die Ausnehmungen 7 eingedrungene Material der Deckschicht 3,
welches anschließend aushärtet, einen im wesentlichen T-förmigen Anker
9, der zu einer bruchfesten Verbindung der Deckschicht 3 mit der Mineralfaserplatte
2 führt.If the liquid or
Selbstverständlich kann der zur Bildung der Anker 9 notwendige Druck
auch unabhängig vom Gewichtsdruck der Deckschicht 3, beispielsweise
durch einen manuell oder maschinell aufgebrachten Druck erzeugt werden.
Von Bedeutung ist hierbei, daß die Ausnehmungen 7 die Faserschicht
5 vollständig und den Abschnitt 6 teilweise durchgreifen, um in
einem Bereich des Dämmstoffelementes 1 angeordnet zu sein, in dem
unterschiedliche Druckfestigkeit in zunehmender Tiefe der Ausnehmungen
7 vorgesehen sind.Of course, the pressure required to form the anchors 9 can
also regardless of the weight pressure of the
In Figur 1 ist mit einer Linie 10 die Herstellung eines entsprechenden
Dämmstoffelementes 1 dargestellt. Hierzu ist vorgesehen, daß ein Vlies
mit im wesentlichen parallel zu seinen großen Oberflächen verlaufenden
Einzelfasern aufgependelt wird, wodurch sich die Fasern in einem überwiegenden
Bereich des derart gebildeten Sekundärvlieses rechtwinklig zu
den großen Oberflächen 4 ausrichten und ausschließlich im Bereich der
beiden gegenüberliegend und parallel zueinander ausgerichteten großen
Oberflächen 4 des Sekundärvlieses parallel zu den großen Oberflächen 4
verlaufen. Wird ein derartiges Sekundärvlies anschließend in seiner Mittelachse
parallel zu den großen Oberflächen 4 in zwei Hälften getrennt
und daraufhin die Ausnehmungen 7 in den Bereich der großen Oberfläche
4 eingebracht, entsteht eine Mineralfaserplatte 2 gemäß Figur 1. In Figure 1 is the production of a corresponding line 10
Insulating
Bei einer anderen Vorgehensweise besteht die Möglichkeit, eine Mineralwollelamellenplatten
mit der üblicherweise dann vorliegenden rechtwinkligen
Ausrichtung der Fasern zu den großen Oberflächen 4 mit einem Faservlies
zu verkleben, welches einen Faserverlauf parallel zu den großen
Oberflächen des Faservlieses aufweist, so daß ein Faserverlauf gemäß
Figur 1 in einer Mineralfaserplatte 2 entsteht.Another approach is to use a mineral wool slat
with the rectangular one usually present
Alignment of the fibers to the
In Figur 2 ist eine alternative Ausgestaltung einer Ausnehmung 7 dargestellt.
Die Ausnehmung 7 ist im wesentlichen V-förmig ausgebildet, wobei
eine Grundfläche 11 der Ausnehmung 7 eine größere Breite aufweist, als
eine Öffnungsbreite 12 der Ausnehmung 7 im Bereich der Faserschicht 5.
Bei dieser Ausgestaltung wird bereits durch eine hinterschnittene Formgebung
eine Verankerung der Deckschicht 3 in der Mineralfaserplatte 2
erzielt, die darüber hinaus noch durch die Faserorientierung in der Faserschicht
5 bzw. dem Abschnitt 6 unterstützt wird. Eine entsprechende Ausnehmung
7 kann beispielsweise während des Herstellungsprozesses
durch spezielle Fräswerkzeuge in die Mineralfaserplatte 2 eingebracht
werden.An alternative embodiment of a recess 7 is shown in FIG.
The recess 7 is substantially V-shaped, wherein
a base 11 of the recess 7 has a greater width than
an
Eine weitere Ausgestaltung einer Ausnehmung 7 ist in Figur 3 dargestellt.
Bei dieser Ausgestaltung weist die Ausnehmung 7 einen parallelogrammartigen
Querschnitt auf, der während des Produktionsprozesses einer
derartigen Mineralfaserplatte 2 durch einen Sägeschnitt in die Mineralfaserplatte
2 eingebracht werden kann.A further embodiment of a recess 7 is shown in FIG. 3.
In this embodiment, the recess 7 has a parallelogram
Cross-section on the during the production process

jeweils eine Stufe 15 aufweisen, die korrespondierend zueinander ausgebildet
sind, so daß benachbarte Dämmstoffelemente 1 fugendicht miteinander
verbunden werden können. Hierbei liegt die Stufe 15 der Schmalseite
14 des benachbarten Dämmstoffelementes 1 in der dafür vorgesevorgesehenen
Ausnehmung im Bereich der Stufe 15 der Schmalseite 13
des in Figur 4 dargestellten Dämmstoffelementes.Finally, an insulation element according to the invention is shown in FIG
complete
Weiterhin ist bei der Ausführungsform gemäß Figur 4 vorgesehen, daß die
Mineralfaserplatte 2 auf ihrer der Deckschicht 3 abgewandten großen
Oberfläche 4 eine Kaschierung 16 aufweist. Mit dieser Kaschierung 16
