Die DD 248 934 A3 offenbart ein Verfahren und eine Vorrichtung zur Herstellung von Produkten mit vorwiegend senkrecht orientierter Faserausrichtung der Mineralwolleprodukte bei der Durchführung des Lamellierens von Mineralfaservliesen. Die Lösung dieses Patentes gewährleistet die Herstellung von Produkten, deren Faserrichtung, bezogen auf die großen Achsen des Produktes, senkrecht gestellt ist. Sie gestattet jedoch nur die Herstellung von Produkten, deren Faserverlauf ohne Unterbrechnung gleichförmig, bezogen auf die großen Achsen des Elementes senkrecht orientiert, gestellt ist. Ein weiterer Nachteil der bekannten Lösung ist darin zu sehen, dass das aus dem lamellierten Faservlies gefertigte Element, nur entlang seiner quer zur Längsmittenachse gerichteten Lamellen, eine große Biegefestigkeit besitzt, jedoch in der Richtung seiner Längsmittenachse einen verminderten Widerstand gegen Biegung aufweist.

The solution of this patent ensures the production of Products whose grain direction, related to the major axes of the product, is placed vertically. However, it only permits the production of products whose Fiber flow is uniform without interruption, based on the major axes of the Element is oriented vertically. Another disadvantage of the known The solution can be seen in the fact that the fabricated from the laminated fiber fleece Element, only along its slats directed transversely to the longitudinal center axis, one has great flexural strength, but one in the direction of its longitudinal center axis reduced resistance to bending.
Der Erfindung liegt die Aufgabe zugrunde, ein Dämmelement aus Mineralwolle zur Verfügung zu stellen, deren Fasern entgegen der Richtung der großen Achsen des Elementes senkrecht orientiert gestellt sind und das bei einem variablen Anwendungsbereich verbesserte physikalische Eigenschaften aufweist.The invention has for its object to provide an insulating element made of mineral wool To make available whose fibers go against the direction of the major axes of the Element are vertically oriented and that with a variable Application has improved physical properties.
Zur Lösung der Aufgabe wird ein Dämmelement gemäß Anspruch 1 vorgeschlagen.To solve the problem, an insulation element according to claim 1 is proposed.
Anmeldungsgemäß kann eine lamellierte, senkrecht im Faserverlauf orientiert ausgebildete Schicht, ein- oder mehrfach ausgeführt, mit Schichten eines gleichen Materials, abweichenden Faserverlaufs oder anders strukturierten Materials in Verbindung gebracht und der Schichtenaufbau des Elementes, im Element sich ein- oder mehrfach wiederholend, angeordnet sein.According to the application, a laminated, oriented vertically in the fiber course trained layer, executed one or more times, with layers of the same Material, deviating fiber course or differently structured material in Connected and the layer structure of the element, in the element or repeated several times.
Die Erfindung findet eine sehr vorteilhafte Ausbildung darin, dass das Element eine lamellierte Schicht mit einem senkrecht ausgerichteten Faserverlauf aufweist, bezogen auf die Erstreckung ihrer großen Flächen aus dazu senkrecht verlaufenden, aus segmentförmigen, sich in der Schichtebene gleichförmig wiederholenden, stegartigen Schichtgruppen gebildet ist, deren Materialaufbau und Zusammensetzung nicht gleichartig gestaltet wurde. Diese Produkte stellen eine äußerst vorteilhafte Entwicklung eines Dämmelementes mit der konsequenten Anwendung und Weiterentwicklung der Produkte dar, die mittels der im Stand der Technik angeführten Lösungen hergestellt werden können. Das Produkt, vorerst in einer Schicht vorliegend, vereint in sich im Faserverlauf senkrecht gestellte Gruppen eines unterschiedlichen Materialaufbaus mit einer stegartigen, senkrechten Schichtstruktur, wobei vorwiegend stegartige Schichten andersstrukturierter Materialien verbunden sind und einen flächigen Dämmkörper bilden. Die Schichten verlaufen hierbei, vorteilhaft ausgebildet, quer zur Längsmittenachse, so dass eine stegartige, sich in Gruppen wiederholende senkrechte Schichtenausbildung geprägt ist. Ein Dämmelement dieser Strukturausbildung weist bisher nicht gekannte Vorteile auf. The invention finds a very advantageous embodiment in that the element is a has a laminated layer with a vertically oriented grain, based on the extension of their large areas from perpendicular from segment-shaped, repetitive in the layer plane, web-like layer groups is formed, their material structure and composition was not designed in the same way. These products represent an extremely beneficial one Development of an insulation element with consistent application and Further development of the products represented by means of the state of the art solutions mentioned can be produced. The product, initially in one In the present layer, groups of one vertically aligned in the course of the fiber are united different material structures with a web-like, vertical Layer structure, with predominantly web-like layers with a different structure Materials are connected and form a flat insulation body. The layers run here, advantageously formed, transversely to the longitudinal center axis, so that a Bridge-like, vertical layer formation repeated in groups is. An insulation element of this structure has previously unknown advantages on.
Die Einfügung von stegartigen Schichten mit einem nicht brennbaren Material hoher Brandschutzklassen, wie Glasfasern, Glasfaservliese u.ä. Material, zwischen Schichten hochverdichteter bzw. wenig verdichteter Materialien geben dem Fachmann den Hinweis, dass neben hoher Formstabilität und überdurchschnittlicher guter Verarbeitbarkeit ein Element erfunden worden ist, das eine variable Anwendungsbreite aufweist und mit hervorragenden physikalischen Eigenschaften ausgestattet ist. Diese vorteilhafte Lösung weiter unterstützend, ist die Erfindung ausgebildet, wenn die Steggruppen der senkrecht verlaufenden Stege aus 2 bis n-mal sich in der Reihenfolge wiederholenden Gruppen eines nicht gleichartigen Aufbaus des Materials und seiner Zusammensetzung gebildet sind: Dabei ist es erfindungsgemäß vorteilhaft und im Sinne des Tenors der erfindungsgemäßen Lösung, dass die sich in sich wiederholenden Gruppen, im Rahmen der Stege, unterschiedliche Festigkeiten und Konsistenzen aufweisen, wobei Stege mit großer Festigkeit, neben Stegen mit geringer Festigkeit, ausgebildet sind und dem Element durch die Stege mit hoher Festigkeit, große Druckfestigkeiten, eine große Formstabilität, ein vermindertes Rückstellverhalten zugeordnet werden können. Der logischen Konsequenz folgend, werden dabei Stegausbildungen mit geringer Festigkeit, ein großes Rückstellvermögen ihres Materials in Richtung der großen Mittenachse des Elementes, verbunden mit einem geringen Gewicht, zugeordnet, was wiederum den Vorteil hat, dass neben dem verminderten Rückstellverhalten der Schichten mit hoher Dichte und Festigkeit dem Element im Rahmen bewußt zugeordneter Schichten verminderter Festigkeit und Formstabilität, eine Anpaßbarkeit an die Bauwerksbedingungen im Detail zugeordnet werden können, die über das bisher bekannte Maß eingeführter Dämmelemente hinausgeht. Damit ist es möglich, auf die Oberflächen solcher Baukörper, die mit Elementen dieser Ausführung gefertigt worden sind, textile Oberflächenbeschichtungen aufzubringen, die nicht durch thermische oder meteorologische Einflüsse reißen, weil sich das Element jetzt dem Dehnverhalten des Beschichtungselementes anpassen kann. Es ist eine besonders vorteilhafte Ausgestaltungsform der Erfindung, wenn die stegartigen Schichten, die mit senkrecht orientiertem Faserverlauf sowie mit unterschiedlichen stegartigen Schichtengruppen ausgebildet sind, um 90° zu ihren großen Mittenachsen verdreht, mit ihren großen Flächen aufeinander angeordnet und verbunden sind. Bei dieser Ausführung der erfindungsgemäßen Lösung subsumieren sich die Vorteile der bereits dargestellten erfindungsgemäßen Ausbildungsvarianten. Da vorteilhafterweise jetzt die Schichtengruppen mit ihrem unterschiedlichen Schichtenaufbau, der darin gebildeten Stege miteinander ungleicher Festigkeit und Dichte kreuzgitterartig übereinander gelegt sind, ergeben sich die vorteilhaften Wirkungen, dass im Bereich übereinander gelegener Stege mit großer Festigkeit, durchgehende Kraftlinien quer zu den großen Mittelachsen und längs zu ihnen durchgehende Kraftlinien mit großen Wechselfestigkeiten sowie hohe Biege- und Verdrehfestigkeiten der flächigen Elemente ausgebildet werden. Es folgt der logischen Konsequenz der erfindungsgemäßen Lösung, dass in den Schichten mit ungleichem Schichtenaufbau die damit gebildeten Stege mit ungleicher Festigkeit und Dichte im Bereich übereinanderliegender Stege mit geringerer Dichte, durchgehende Kraftlinien mit geringer Festigkeit, sowie geringerer Dichte eines hohen Rückstellvermögens und großer Dämmwirkung gebildet sind. Die bewußte Einbindung von Materialien mit hohen Brandverhütungsklassen läßt die universelle Einsetzbarkeit der Elemente nicht nur im Bauwesen, sondern auch im Schiffbau, im Fahrzeugbau u.v.m. zu. Die erfindungsgemäße Lösung erfüllt die gestellte Aufgabe eines nichtbrennbaren Elementes indem nicht brennbare Bindemittel und Kleber verwendet worden sind.The insertion of web-like layers with a non-combustible material of high fire protection classes, such as glass fibers, glass fiber fleeces and the like. Material, between layers of highly compressed or less compressed materials give the expert the indication that in addition to high dimensional stability and above-average good processability, an element has been invented that has a variable range of applications and is endowed with excellent physical properties. To further support this advantageous solution, the invention is designed if the web groups of the perpendicular webs are formed from 2 to n times repeating groups of a non-similar structure of the material and its composition: it is advantageous according to the invention and in the sense of the tenor of the solution according to the invention that the repetitive groups, within the framework of the webs, have different strengths and consistencies, webs with high strength being formed in addition to webs with low strength, and the element being large due to the webs with high strength Compressive strengths, great dimensional stability, reduced resilience can be assigned. Following the logical consequence, web designs with low strength, a large resilience of their material in the direction of the large central axis of the element, combined with a low weight, are assigned, which in turn has the advantage that, in addition to the reduced resilience behavior of the layers with high density and Strength can be assigned to the element in the context of consciously assigned layers of reduced strength and dimensional stability, adaptability to the building conditions in detail, which goes beyond the previously known level of introduced insulation elements. It is thus possible to apply textile surface coatings to the surfaces of such structures which have been produced using elements of this embodiment, which do not tear due to thermal or meteorological influences, because the element can now adapt to the stretching behavior of the coating element. It is a particularly advantageous embodiment of the invention if the web-like layers, which are formed with a vertically oriented fiber course and with different web-like layer groups, are rotated by 90 ° to their large central axes, are arranged with their large areas on top of one another and connected. In this embodiment of the solution according to the invention, the advantages of the training variants according to the invention already described are subsumed. Since the layer groups with their different layer structure, the webs formed therein with the different strength and density of each other are advantageously laid cross-lattice-like one above the other, there are the advantageous effects that in the area of superposed webs with great strength, continuous lines of force transversely to the large central axes and along continuous lines of force with high fatigue strength as well as high bending and torsional strength of the flat elements are formed. It follows the logical consequence of the solution according to the invention that in the layers with an uneven layer structure the webs thus formed are formed with uneven strength and density in the area of superimposed webs with lower density, continuous lines of force with low strength, as well as lower density with a high resilience and great insulating effect , The deliberate integration of materials with high fire prevention classes allows the universal usability of the elements not only in construction but also in shipbuilding, vehicle construction and much more. The solution according to the invention fulfills the task of a non-combustible element by using non-combustible binders and adhesives.
Die Erfindung findet eine vorteilhafte Ausbildung darin, dass im Rahmen des beanspruchten Verfahrens das zugefĂĽhrte Faservlies mehrschichtig in eine zufĂĽhrende Transporteinrichtung eingeleitet und in der Einrichtung gefĂĽhrt, einem Scheitelpunkt entgegen bewegt wird. An dem Scheitelpunkt wird das zugefĂĽhrte mehrschichtige Faservlies in Lamellen zertrennt. Die abgetrennten Lamellen bilden jetzt zusammengefĂĽgte Schichtanordnungen eines Vlieses, das stegartige Lamellenanordnungen aufweist, die in der Anzahl sowie Materialzusammensetzung der Schichten entsprechende stegartige Lamellengruppen bilden, die beim Trennen auf die Auflage- und Abtransporteinrichtung geschoben werden und von dort zu einem einheitlichen, mehrere Schichtgruppen aufweisenden Element kontinuierlich weiter verarbeitet werden. The invention finds an advantageous embodiment in that in the context of claimed process the supplied nonwoven in a multi-layered feeding transport device initiated and guided in the device, one Vertex is moved towards. At the vertex, that is fed multi-layer fiber fleece separated into lamellas. Form the separated slats now assembled layer arrangements of a fleece, the web-like Has lamellar arrangements, the number and material composition the layers form corresponding web-like lamella groups, which during separation be pushed onto the support and removal device and from there a uniform, multi-layer element processed further.

Fig. 12 und 13 zeigen ein lamelliertes, mit vorwiegend senkrechtem Faserverlauf
ausgestaltetes Element a Das Element a weist Gruppen 21 von senkrechten
stegförmigen Schichten 19;20 auf, die eine unterschiedliche
Materialzusammensetzung haben, wobei die Gruppen 21 sich zyklisch oder azyklisch
wiederholen können. Das Element a kann in unterschiedlichen Dicken ausgebildet
sein und wird unter Anwendung des Lamellierverfahrens gem. DD Patent 248934 A3,
das in seiner schöpferischen Anwendung nach Fig. 18 noch nähere Erläuterungen
finden soll, entsprechend der Lösung, einer das Patent weiterführenden
Patentanmeldung hergestellt. Die Gruppen 21 sind in ihren stegförmigen Schichten
19;20 unterschiedlich ausgebildet. So sind die Stege 19;20 in ihren
Materialzusammensetzungen verschiedenartig zusammengestellt, wobei die Stege 19
vorwiegend aus einem Fasermaterial mit senkrecht orientierten, lamelliertem
Faserverlauf gebildet sind. Der oder die Stege 20 können eine untereinander anders
ausgebildete Materialzusammensetzung erhalten. So ist es möglich, das Material der
Stege 20 dem Längsverlauf der Stege 19 parallel laufend, horizontal zur Fläche 2a
anzuordnen, bzw. Materialien zu verwenden, die granulatförmig, aus Glasfasern oder
Glasfaservlies gebildet sind. Auf jeden Fall ist es jetzt gelungen, in die Einzelstege
19 der Steggruppen 21 Stege zu implizieren, die eine andersartige
Materialausbildung aufweisen und das physikalische Verhalten der Platten bei der
Anwendung äußerst positiv beeinflussen, so däss eine höchstmögliche
Wärmedämmfähigkeit gemeinsam mit hervorragenden Schallschutzeigenschaften und
einem ausgezeichneten Brandschutzverhalten erreicht werden können.
Die Fig. 14 zeigt ein Dämmelement der erfindungsgemäßen Art, bei der zwei
Elemente als Schichten 22,22' an der Verbindungsstelle 2 zusammengefĂĽhrt sind.
Das Zusammenfügen der Schichten erfolgt derart, dass die Stege 19;20 um 90°
verdreht aufeinander zu liegen kommen. Dadurch entsteht ein sich kreuzgitterartig
darstellendes Dämmelement aus mehreren, aber mindestens zwei Schichten. Fig. 15
zeigt in seiner Darstellung die Anordnung der Stege 19;20 in den Schichten 22;22'.
Der Halbschnitt zeigt, dass die untere Schicht 22', von in der Tafelebene gesehen,
senkrecht gerichtete Steggruppen 21 aufweist und die darüberliegende Platte um 90°
verdreht und dazu verlaufende Steggruppen 21, so dass hier, wie auch in Fig. 16
dargestellt, eine kreuzgitterartige Struktur sich abwechselnd ĂĽberdeckender
Steggruppen 21 von Stegen 19 senkrecht orientierten Faserverlaufs und Stegen 20
andersartigen Materials ergibt. Der lesende Fachmann erhält jetzt die Information,
dass hier ein Dämmelement zur Aufnahme großer statischer Belastungen sowie
hervorragender physikalischer Eigenschaften, wie Dämmeinwirkung und
Brandschutzverhalten, entstanden ist. Allein die Biege- und Zugwechselfestigkeit
dieses Elementes ist hervorragend gesichert, wobei weiterhin, gesehen zu den
großen Flächen, im Querverlauf der Kräfte, Zonen hoher Druckaufnahme mit
elastischen Zonen gepaart sind und damit eine erhebliche statische Belastbarkeit des
Elementes in Bezug auf Verdrehsicherheit sowie Rückstellvermögen gesichert ist.
Die Einbindung von Stegen 19;20 unterschiedlicher Materialzusammensetzung in
sich kreuzenden Steggruppen 21 läßt sich auch bei Elementen realisieren, deren sich
kreuzender Stegverlauf um 45° im Schichtenaufbau verdreht ist. Das ergibt dann
Dämmelemente mit annähernd zu ihren großen Achsen diagonal verlaufenden Stegen
19;20 und Steggruppen 21. Eine derartige AusfĂĽhrung bietet sich insbesondere bei
quadratischen Platten an, die an horizontalen Baukörpern angeordnet werden. Dem
mitlesenden Fachmann wird selbstverständlich ohne erfinderisches Handeln klar, dass
bei Kenntnis der zweischichtigen Ausführungen der Dämmplatte mit sich in 90° oder
auch 45° kreuzenden schichtartigen Stegen 19;20 und Steggruppen 21 auch
Ausführungen von 2 bis n Schichten 22;22' möglich sind. Hier unterliegt es den
technologischen Anforderungen der Praxis, Dämmelemente mit solchem
Schichtaufbau zu fordern, die dann auch hergestellt werden können. Es ist den
Dämmelementen gem. Fig. 12 bis 16 eigen, dass sie ohne stützende Hilfsmittel wie
Trägergerüsten, Stützwänden u.ä., als selbstständige Wandelemente in Bauwerken
Verwendung finden können. Zur besseren Lagefixierung in einem Bauwerksverbund,
z.B. bei der Errichtung von Trockenwänden, können die Stirn- und Seitenflächen mit
nut- oder federartigen Fixierungselementen versehen werden, welche die Elemente
selbstständig in ihrer Lage fixieren oder auch Mörtel oder Kleber aufnehmen, um die
Elemente in der Wandflucht an ihren Stirn- und Seitenflächen miteinander zu
verbinden. Die Fixierungselemente sind, da sie einmal sehr vielgestaltig sein können
und zum anderen dem Fachmann in der Ausbildung an sich bekannt sind, in der
Zeichnung nicht gesondert dargestellt.12 and 13 show a laminated element a, which is designed with a predominantly vertical fiber orientation. The element a has
14 shows an insulation element of the type according to the invention, in which two elements are brought together as
Die Fig. 17 zeigt die Herstellung der stegartigen Steggruppen 21 des Dämmelementes. Aus einer kontinuierlich arbeitenden Einrichtung gemäß einer bereits gefundenen neuen Lösung wird einem Rollgang, bestehend aus Rollen 28;29, ein aus drei Schichten 31; 32; 33 gebildetes Rohfaservlies 23 zugeleitet und entsprechend dem bekannten Verfahren verdichtet. Ein in 45° nach oben gerichteter Strang des Rohfaservlies mit seinen Schichten 31; 32; 33, jetzt entsprechend verdichtet, wird einer geeigneten Schneidvorrichtung zugeleitet, hier bestehend aus einem Pendel 26 mit einer Schneide 25, welche das vorrückende Faservlies 23 abschneidet und die geschnittenen lamellierten Teile des Faservlieses der Faserlamelle 24 einem Auflagetisch 30 zugeordnet, der im Winkel von 90° zu dem aufsteigenden Teil des Rollganges gerichtet ist. Es ist für den Fachmann selbstverständlich, dass ein Schneiden mit dem Pendel 26 nicht die einzige Möglichkeit ist, das Faservlies zu durchtrennen. Es können Möglichkeiten des Trennens mittels eines Schneidedrahtes bis hin zum Laserstrahl weitestgehend zur Anwendung gelangen. Gemäß diesem Verfahren werden jetzt, wie aus der Einzelheit X entsprechend Fig. 18 zu erkennen ist, lamellierte Gruppen 21 mit unterschiedlichen Stegen 19;20 versehender Elementbestandteile zum Zusammenfügen eines schichtartigen Dämmelementes mit unterschiedlichen Materialzusammensetzungen in seinen Steggruppen dem weiteren Fertigungsprozeß zugeführt. Wie Fig. 18 zeigt, sind jetzt, das bekannte Verfahren zum Herstellen von Mineralfaservliesen mit vorwiegend senkrecht orientierter Faserausrichtung, beim Lamellieren von Mineralfaservliesen schöpferisch anwended, lamellierte, senkrecht orientierte Stege 20 aus Mineralfasern mit Stegen 19 Materialien gleicher Art, aber anderer Struktur, als Gruppen 21 zusammengeführt, hergestellt worden. Die aus diesen Steggruppen 21 zusammengefügten Dämmelemente mit ausgewählter Dicke und Schichtanzahl nach der Erfindung, weisen ausgezeichnete statische Eigenschaften auf und empfehlen sich für eine Anwendung in unterschiedlichen Bereichen, beispielsweise des Bauwesens, des Schiffs-, Fahrzeug- und des Stahlbehälterbaus.
