Description

Wandung wall

Die Erfindung betrifft eine Wandung, insbesondere eine Schiffswandung, bestehend aus zumindest einem großflächigen Wandelement, auf dem zur Aussteifung des Wandelementes zumindest ein stegförmiges Element angeordnet ist, welches sich insbesondere parallel zur Flächennormalen des Wandelementes erstreckt, und zumindest einem Dämmelement, welches aus Mineralfasern besteht und im Wesentlichen mit einer großen Oberfläche am Wandelement anliegt und zumindest ein stegförmiges Element übergreift.The invention relates to a wall, in particular a ship's wall, consisting of at least one large-area wall element on which at least one web-shaped element is arranged for stiffening the wall element, which element extends in particular parallel to the surface normal of the wall element, and at least one insulating element which consists of mineral fibers and essentially rests on the wall element with a large surface and engages over at least one web-shaped element.

Derartige Wandungen sind aus dem Stand der Technik bekannt. In der Regel handelt es sich hierbei um Wandungen aus Metall, insbesondere Stahl oder Aluminium sowie aus Kunststoff. Derartige Wandungen werden aus großformatigen Platten dieser Materialien hergestellt und weisen zur Erhöhung ihrer Stabilität, ins- besondere zur Verbesserung ihrer Widerstandsfähigkeit gegen Beulen, stegförmi- ge Element, beispielsweise auch in Form von Sicken auf. Diese Wandungen werden beispielsweise als Bordwände oder Decks von schwimmenden Körpern, wie Schiffen, Bohrplattformen oder dergleichen verwendet. Die stegförmigen Elemente können integraler Bestandteil der Wandung oder durch Befestigungsmittel mit der Wandung verbunden sein. Beispielsweise können diese stegförmigen Elemente durch Aufschweißen, mit Hilfe von Nieten und/oder mittels Klebemitteln, kraft- und formschlüssig am großflächigen Wandelement angeordnet sein.Such walls are known from the prior art. As a rule, these are walls made of metal, in particular steel or aluminum, and made of plastic. Walls of this type are produced from large-format sheets of these materials and, in order to increase their stability, in particular to improve their resistance to dents, have web-shaped elements, for example also in the form of beads. These walls are used, for example, as drop sides or decks of floating bodies, such as ships, drilling platforms or the like. The web-shaped elements can be an integral part of the wall or connected to the wall by fastening means. For example, these bar-shaped elements can be arranged on the large-area wall element by welding, with the aid of rivets and / or by means of adhesives, in a non-positive and positive manner.

Die stegförmigen Elemente können unterschiedlich profiliert sein. Im einfachsten Fall handelt es sich beispielsweise um stegförmige Elemente mit rechteckigem Querschnitt. Üblicherweise werden aber auch solche stegförmigen Elemente an den großflächigen Wandelementen befestigt, die im Querschnitt L-förmig, T-förmig oder Doppel-T-förmig ausgebildet sind. Im Schiffbau werden darüber hinaus stegförmige Elemente verwendet, die als sogenannte HP-Profile bezeichnet werden. Bei diesen Profilen ist das raumseitige Ende des stegförmigen Elementes wulstartig urngebogen. Neben der Verwendung derartiger Wandungen im Schiffsbau können derartige Wandungen selbstverständlich auch bei technischen Anlagen vorgesehen sein. Nachfolgend wird die Erfindung aber im Wesentlichen hinsichtlich einer Schiffswandung erläutert.The web-shaped elements can be profiled differently. In the simplest case, these are, for example, web-shaped elements with a rectangular cross section. Usually, however, those web-shaped elements are also attached to the large-area wall elements, which are L-shaped, T-shaped or double-T-shaped in cross section. In shipbuilding, web-shaped elements are also used, which are referred to as so-called HP profiles. In these profiles, the end of the web-shaped element on the room side is bent in a bead-like manner. In addition to the use of such walls in shipbuilding, such walls can of course also be provided in technical systems. In the following, however, the invention is essentially explained with regard to a ship's wall.

Wandungen, insbesondere Schiffswandungen müssen zum einen gegen Wärmeverlust und zum anderen gegen die Bildung von Tauwasser geschützt werden. Ferner ist der Brandschutz bei derartigen Wandungen sehr bedeutungsvoll. Für die Vermeidung des Wärmeverlustes und die Erhöhung des Brandschutzes wer- den daher vornehmlich nicht brennbare oder zumindest schwer entflammbare Dämmelemente verwendet, deren tatsächliche Eignung als Brandschutzelemente in entsprechenden Bauteil-Prüfungen nachzuweisen ist. Vorzugsweise finden daher Glaswolle-Dämmstoffe Verwendung. Derartige Dämmstoffe bestehen aus glasig erstarrten Fasern, die in der Regel mit geringen Mengen duroplastisch aushär- tender Gemische von Phenol-Formaldehyd-Harnstoffharzen gebunden werden. Zur Hydrophobierung und zur Staubbindung werden darüber hinaus hoch siedende Mineralöle in der Mineralfasermasse verteilt angeordnet. Glaswolle- Dämmstoffe werden aus silikatischen Schmelzen hergestellt, die relativ hohe Anteile an Alkalien oder Boroxiden aufweisen. Nachteilig bei derartigen Glaswolle- Dämmstoffen ist aber die Neigung zur Sinterung bzw. zu einem Aufschmelzen bei Temperaturen oberhalb von ca. 600° C. Glaswolle-Dämmstoffe können deshalb im Brandfall nur ganz kurze Zeit Widerstand leisten.Walls, in particular ship walls, must be protected against heat loss on the one hand and against the formation of condensation on the other. Fire protection is also very important for such walls. In order to avoid heat loss and increase fire protection, non-combustible or at least flame-retardant insulation elements are primarily used, and their actual suitability as fire protection elements must be proven in corresponding component tests. Glass wool insulation materials are therefore preferably used. Such insulating materials consist of glassy solidified fibers, which are usually bonded with small amounts of thermosetting curing mixtures of phenol-formaldehyde-urea resins. In addition, high-boiling mineral oils are distributed in the mineral fiber mass for water repellency and dust binding. Glass wool insulation materials are made from silicate melts that have relatively high proportions of alkalis or boron oxides. A disadvantage of such glass wool insulation materials is the tendency to sinter or melt at temperatures above approx. 600 ° C. Glass wool insulation materials can therefore only resist for a very short time in the event of a fire.

Die Zerfaserung einer Glasschmelze erfolgt zumeist in Zerfaserungsaggregaten, die einen rotierenden, schüsselartig ausgebildeten Zerfaserungsteller aufweisen. Dieser Zerfaserungsteller hat gelochte Wandungen, durch die die Glasschmelze aufgrund der Zentrifugalkraft austritt und dabei zu Mineralfasern verformt wird. Die Mineralfasern werden in einem unterhalb des Zerfaserungstellers angeordneten Fallschacht mit Bindemitteln und sonstigen Zusätzen, beispielsweise den hoch siedenden Mineralölen imprägniert und auf einer langsam laufenden Fördereinrichtung aufgesammelt. Mehrere derartige Zerfaserungsaggregate sind hintereinander angeordnet, um die für eine wirtschaftliche Produktion erforderliche Fasermasse zu gewinnen. Die nacheinander erfolgende Ablagerung der Mineralfasern führt im Bezug auf die derart ausgebildete endlose Faserbahn zu einem Ausgleich der in jeder Lage vorhandenen Inhomogenitäten.A glass melt is mostly defibrated in defibration units that have a rotating, bowl-shaped defibration plate. This defibration plate has perforated walls through which the glass melt emerges due to the centrifugal force and is thereby deformed into mineral fibers. The mineral fibers are impregnated with binders and other additives, for example the high-boiling mineral oils, in a chute located below the defibration plate and collected on a slow-moving conveyor. Several such fiberizing units are arranged one behind the other in order to obtain the fiber mass required for economical production. The sequential deposition of the mineral fibers leads to a compensation of the inhomogeneities present in each layer in relation to the endless fiber web formed in this way.

Die voranstehend beschriebene Vorgehensweise zur Bildung von Mineralfasern aus einer Glasschmelze führt durch die Zusammensetzung der Glasschmelze und durch die Art der Zerfaserung zur Bildung relativ langer glatter Mineralfasern, die auf der Fördereinrichtung ohne ausgesprochene Vorzugsrichtung flach übereinander liegend abgelagert werden.The procedure described above for the formation of mineral fibers from a glass melt leads through the composition of the glass melt and through the type of fiberization to the formation of relatively long smooth mineral fibers which are deposited flat on top of one another on the conveyor device without a pronounced preferred direction.

Dämmelemente aus Glaswolle werden im allgemeinen mit Rohdichten von weniger als 45 kg/m3, insbesondere weniger als 30 kg/m3 hergestellt. Eine aus Glaswolle hergestellte Mineralfaserbahn braucht daher nur leicht in ihrer Höhe zusammengedrückt und ihre Struktur durch Aushärten des jeweiligen Bindemittels mittels hindurchgesaugter Heißluft fixiert zu werden. Charakteristisch für die auf diese Weise hergestellten Dämmstoffe aus Glaswolle ist ihre relativ hohe Zugfestigkeit parallel zu den beiden Raumachsen in den Ebenen der großen Oberflächen der Dämmstoffe und die geringe Querzugfestigkeit rechtwinklig zu den beiden erstgenannten Richtungen. Werden derartige Dämmelemente auf Biegung beansprucht, so erfolgt die Verformung zum einen durch die entsprechende Biegbarkeit einzel- ner Mineralfasern oder Mineralfaserlagen, als auch durch Relativbewegungen der Mineralfaserlagen innerhalb des Dämmelementes.Insulating elements made of glass wool are generally produced with bulk densities of less than 45 kg / m 3 , in particular less than 30 kg / m 3 . A mineral fiber web made of glass wool therefore only needs to be slightly compressed in height and its structure to be fixed by curing the respective binder by means of hot air drawn through it. Characteristic of the glass wool insulation materials produced in this way is their relatively high tensile strength parallel to the two spatial axes in the planes of the large surfaces of the insulation materials and the low transverse tensile strength perpendicular to the first two directions. If such insulation elements are subjected to bending, the deformation takes place on the one hand through the corresponding bendability of individual mineral fibers or mineral fiber layers, as well as through relative movements of the mineral fiber layers within the insulation element.

Ausgehend von diesem Stand der Technik liegt der Erfindung die A u f g a b e zugrunde, eine gattungsgemäße Wandung dahingehend weiterzubilden, dass ins- besondere der Brandschutz verbessert ist, die Wandung aber darüber hinaus auch eine verbesserte Wärmedämmung und einen verbesserten Schutz gegen die Bildung von Tauwasser aufweist.Starting from this prior art, the invention is based on the object of developing a generic wall in such a way that fire protection is improved in particular, but the wall also has improved thermal insulation and improved protection against the formation of condensation.

Die L ö s u n g dieser Aufgabenstellung sieht erfindungsgemäß vor, dass das Dämmelement eine Temperaturbeständigkeit von mehr als 1.000° C gemäß DIN 4102, Teil 17 aufweist und dass das Dämmelement auf seinen beiden großen Oberflächen ein Gittergewebe aufweist, welches eine Flexibilität hat, die die Verformbarkeit des Dämmelementes nicht einschränkt. Bei einer derartigen Wandung ist der Brandschutz wesentlich verbessert. Darüber hinaus ermöglicht die Anordnung eines Gittergewebes auf jeder der großen Oberflächen des Dämmelementes eine verbesserte Aussteifung der Wandung, wobei gleichzeitig eine Verformbarkeit des Dämmelementes gegeben ist, die es ermöglicht, das Dämmelement auch im Bereich der stegförmigen Elemente derart anzuordnen, dass es annähernd vollflächig am Wandelement und am stegförmigen Element anliegt. Hierdurch werden Unstetigkeitsstellen bei der Wärmedämmung vermieden.The solution to this problem provides according to the invention that the insulating element has a temperature resistance of more than 1,000 ° C according to DIN 4102, part 17 and that the insulating element has a mesh fabric on its two large surfaces, which has a flexibility that the deformability of the Insulation element is not restricted. With such a wall, fire protection is significantly improved. In addition, the arrangement of a mesh fabric on each of the large surfaces of the insulating element enables an improved stiffening of the wall, while at the same time there is a deformability of the insulating element, which makes it possible to arrange the insulating element in the area of the web-shaped elements in such a way that it covers the entire wall element and rests on the web-shaped element. This prevents discontinuities in the thermal insulation.

Der verbesserte Brandschutz, insbesondere die Temperaturbeständigkeit von mehr als 1.000° C wird bei einer erfindungsgemäßen Wandung dadurch erzielt, dass das Dämmelement aus Steinwolle ausgebildet ist.The improved fire protection, in particular the temperature resistance of more than 1,000 ° C., is achieved with a wall according to the invention in that the insulating element is made of rock wool.

Basis für die Herstellung von Dämmstoffen aus Steinwolle sind erdalkalireiche, eisenoxidhaltige Si02-Al203-Glasschmelzen. Die Faserbildung erfolgt auf sogenannten Kaskaden-Zerfaserungsmaschinen, mit denen gleichzeitig Mineralfasern und nicht faserige Partikel gebildet werden, wobei die nicht faserigen Partikel überwiegend abgeschieden werden. Die hierbei gebildeten Mineralfasern sind sehr kurz und zudem auch noch in sich gebogen. Die Mineralfasern aus einer Gesteinsschmelze werden ebenfalls zur Bildung einer endlosen Mineralfaserbahn direkt auf einer Fördereinrichtung aufgesammelt, wobei üblicherweise ein sogenanntes dünnes Primärvlies gebildet wird, welches anschließend durch eine Pendelvorrichtung quer zu seiner Förderrichtung auf einer nachgeschalteten Förder- richtung abgelegt wird. Diese zweite Mineralfaserbahn wird als Sekundärvlies bezeichnet und dient der Herstellung der Dämmelemente, so dass das Sekundärvlies im Hinblick auf die angestrebte Dicke und Rohdichte der Dämmelemente in der erforderlichen Höhe kontinuierlich auf der zweiten Fördereinrichtung abgelegt wird.The basis for the production of stone wool insulation materials is high-earth alkali, iron oxide-containing Si0 2 -Al 2 0 3 glass melts. The fiber formation takes place on so-called cascade fiberizing machines, with which mineral fibers and non-fibrous particles are simultaneously formed, the non-fibrous particles being predominantly separated. The mineral fibers formed here are very short and, moreover, are also curved. The mineral fibers from a rock melt are also collected directly on a conveying device to form an endless mineral fiber web, a so-called thin primary fleece usually being formed, which is then deposited by a pendulum device transversely to its conveying direction on a downstream conveying direction. This second mineral fiber web is referred to as secondary fleece and is used to manufacture the insulation elements, so that the secondary fleece is continuously deposited on the second conveying device at the required height with regard to the desired thickness and bulk density of the insulation elements.

Entsprechende Dämmelemente aus Steinwolle werden in Form von Matten, Dämmfilzen, Platten oder sonstigen Formkörpern hergestellt. Die Matten bestehen aus schwach gebundenen Mineralfasermassen, die zumeist mit einer Träger- schicht verbunden sind. Bekannt sind darüber hinaus Drahtnetzmatten, bei denen auf einer Oberfläche ein Drahtnetz angeordnet ist, welches mit der Mineralfasermatte insbesondere versteppt oder vernäht ist. Derartige, einseitig mit einem Drahtgeflecht ausgebildete Drahtnetzmatten dienen beispielsweise auch der Dämmung heißgehender Anlagen und können bis zu Temperaturen von 600° C verwendet werden. Vorzugsweise weisen derartige Drahtnetzmatten Rohdichten von mehr als 70 kg/m3, insbesondere von mehr als 90 kg/m3 auf. Durch die hohen Rohdichten und die Verbindung der Drahtgeflechte mit der Mineralfasermatte eignen sie sich aber nicht zur Dämmung hier in Rede stehender Wandungen.Corresponding insulation elements made of stone wool are manufactured in the form of mats, insulation felts, panels or other shaped bodies. The mats consist of weakly bound mineral fiber masses, which are usually layer are connected. In addition, wire mesh mats are known in which a wire mesh is arranged on one surface and is quilted or sewn with the mineral fiber mat. Such wire mesh mats formed on one side with a wire mesh also serve to insulate hot systems and can be used up to temperatures of 600 ° C. Such wire mesh mats preferably have bulk densities of more than 70 kg / m 3 , in particular more than 90 kg / m 3 . Due to the high bulk densities and the connection of the wire mesh with the mineral fiber mat, they are not suitable for the insulation of the walls in question.

Eine Weiterbildung der erfindungsgemäßen Wandung sieht daher vor, dass das Dämmelement als insbesondere elastifizierter Dämmfilz ausgebildet ist. Dämmfilze sind beispielsweise einen Meter breite und mehrere Meter lange Mineralfaserbahnen, die zumeist in Form von komprimierten Rollen gehandelt werden, so dass sie in einfacher Weise transportiert und gelagert werden können. Gleichzeitig weisen Dämmfilze durch ihre Eignung zum gerollten Transport und Lagern auch den Vorteil auf, dass sie im Bereich eines beschränkten Raumangebots, beispielsweise in einem Schiffsrumpf in vorteilhafter, da einfacher Weise gehandhabt werden können. Derartige Dämmfilze aus Steinwolle haben somit den Vorteil, dass sie einerseits großflächig ausgebildet sind und andererseits aufgrund ihrer Rollbarke it in einfacher Weise auch in beengten Raumverhältnissen verarbeitbar sind. Dämmfilze können sowohl mit oder auch ohne Trägermaterial, d.h. einer Trägerschicht ausgebildet sein. Wird ein Trägermaterial oder eine Trägerschicht verwendet, so besteht die in der Regel aus einer Aluminiumfolie, die auf die Mineralfaserbahn des Dämmfilzes kaschiert ist. Hierbei ist lediglich zu berücksichtigen, dass entsprechende Aluminiumfolien nicht bei jedem Anwendungsfall von Vorteil sind, da sie gegebenenfalls als Dampfbremse dienen können, so dass Feuchtigkeit zwischen dem Wandelement und der Aluminiumfolie im Dämmelement verbleibt und gegebenenfalls zur Korrosion führen kann. Andererseits vermindern die Alumini- umfolien die Rissgefahr des Dämmfilzes bei der Dämmung von Wandelemente mit geringen Krümmungsradien, insbesondere im Bereich von stegförmigen Elementen, so dass sie hier der Verbesserung der Biegefestigkeit der Dämmfilze dienen. Alternativ zu Aluminiumfolien können die Dämmfilze mit Glasfasergewebe verstärkt sein.A further development of the wall according to the invention therefore provides that the insulating element is designed as a particularly elasticized insulating felt. Insulating felts are, for example, mineral fiber webs one meter wide and several meters long, which are usually traded in the form of compressed rolls so that they can be transported and stored in a simple manner. At the same time, due to their suitability for rolled transport and storage, insulation felts also have the advantage that they can be handled in an advantageous, simple manner in the area of limited space, for example in a ship's hull. Insulating felts of stone wool of this type therefore have the advantage that, on the one hand, they have a large area and, on the other hand, due to their rollability, they can be processed in a simple manner even in confined spaces. Insulating felts can be designed with or without a carrier material, ie a carrier layer. If a carrier material or a carrier layer is used, it usually consists of an aluminum foil which is laminated onto the mineral fiber web of the insulating felt. It should only be taken into account here that appropriate aluminum foils are not advantageous in every application, since they can possibly serve as a vapor barrier, so that moisture remains between the wall element and the aluminum foil in the insulating element and can possibly lead to corrosion. On the other hand, the aluminum foils reduce the risk of tearing of the insulating felt when insulating wall elements with small radii of curvature, in particular in the area of web-shaped elements, so that they serve to improve the bending strength of the insulating felts. As an alternative to aluminum foils, the insulation felts can be reinforced with glass fiber fabric.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass das Dämmele- ment eine Rohdichte zwischen 21 und 35 kg/m3, insbesondere zwischen 25 und 29 kg/m3 und/oder einen Bindemittelgehalt zwischen 1,5 und 2,7 Masse-% aufweist. Dämmelemente mit der bevorzugten Rohdichte und dem bevorzugten Bindemittelgehalt sind einerseits ausreichend stabil, um ein Zerbrechen der Dämmelemente bei der Montage vermeiden zu können. Andererseits sind diese Dämm- elemente ausreichend flexibel, insbesondere biegbar, um sie auch im Bereich der stegförmigen Elemente möglichst vollflächig an das Wandelement und die stegförmigen Elemente anzulegen.According to a further feature of the invention, it is provided that the insulation element has a bulk density between 21 and 35 kg / m 3 , in particular between 25 and 29 kg / m 3 and / or a binder content between 1.5 and 2.7 mass% having. On the one hand, insulation elements with the preferred bulk density and the preferred binder content are sufficiently stable to be able to avoid breaking the insulation elements during assembly. On the other hand, these insulation elements are sufficiently flexible, in particular bendable, in order to apply them to the wall element and the web-shaped elements as far as possible even in the area of the web-shaped elements.

Das Gittergewebe ist vorzugsweise als Fasergittergewebe aus Glasfasern, Koh- lenstofffasem, Kunststofffasern, Naturfasern und/oder Drähten mit geringemThe mesh fabric is preferably a fiber mesh fabric made of glass fibers, carbon fibers, plastic fibers, natural fibers and / or wires with little

Durchmesser < 0,8 mm ausgebildet. Insbesondere die Verwendung eines Fasergittergewebes aus Glasfasern, Kohlenstofffasern, Kunststofffasern oder Naturfasern hat den Vorteil, dass derartige Fasergittergewebe zum einen eine hohe Stabilität und zum anderen eine große Biegbarkeit aufweisen, so dass wiederum das Dämmelement in seiner Formgebung ausreichend stabil ist und gleichzeitig eine Biegung ermöglicht, die ein Anlegen des Dämmelementes an die stegförmigen Elemente erleichtert.Diameter <0.8 mm. In particular, the use of a fiber mesh fabric made of glass fibers, carbon fibers, plastic fibers or natural fibers has the advantage that such fiber mesh fabrics on the one hand have high stability and on the other hand have great flexibility, so that in turn the shape of the insulating element is sufficiently stable and at the same time enables it to bend, which facilitates placing the insulation element on the web-shaped elements.

Vorzugsweise hat das Gittergewebe eine Gitterweite zwischen 5 mm und 25 mm, wobei das Gittergewebe insbesondere quadratisch ausgebildete Maschen mit einer Kantenlänge von 10 mm aufweist.The mesh fabric preferably has a mesh width between 5 mm and 25 mm, the mesh fabric in particular having square meshes with an edge length of 10 mm.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass das Gittergewebe mit dem Dämmelement verklebt ist. Beispielsweise kann das Gittergewebe vor dem Aushärten des Bindemittels innerhalb des Dämmelementes auf die großen Oberflächen des Dämmelementes aufgelegt und im Härteofen angepresst werden, so dass die Verklebung des Gittergewebes mit dem Dämmelement durch das Bindemittel im Dämmelement erfolgt. Selbstverständlich kann auch vorgese- hen sein, dass das Gittergewebe mit einem ergänzenden Klebstoff auf die Oberflächen des Dämmelementes aufgeklebt ist.According to a further feature of the invention, it is provided that the mesh fabric is glued to the insulation element. For example, the mesh fabric can be placed inside the insulation element on the large surfaces of the insulation element and pressed in the hardening furnace before the binder hardens, so that the bonding of the mesh fabric to the insulation element takes place through the binder in the insulation element. Of course, hen that the mesh fabric is glued to the surfaces of the insulating element with a supplementary adhesive.

Das Dämmelement weist mit dem Gittergewebe eine über seine Länge, Breite und Höhe gleichbleibende Verformbarkeit auf. Hierzu wird das Dämmelement, insbesondere der Dämmfilz durch eine kontrollierte Kompression und Dekompression in Richtung der Flächennormalen seiner großen Oberflächen und einer gleichzeitigen wechselgerichteten Biegung elastifiziert. Zu diesem Zweck wird der Dämmfilz beispielsweise durch mehrere Walzengänge gefördert, die zum einen die erforder- liehe Kompression bzw. Dekompression und zum anderen die wechselseitige Biegung des Dämmfilzes ausführen. Durch die starken Kompressionen und die wechselgerichteten Biegungen werden festere Bereiche des Dämmfilzes, beispielsweise auch Inhomogenitäten in der Mineralfaser- und/oder der Bindemittelverteilung aufgebrochen, um eine gleichmäßige Verformbarkeit des Dämmfilzes bzw. der daraus hergestellten Dämmelemente zu erreichen.With the lattice fabric, the insulation element has a deformability that is constant over its length, width and height. For this purpose, the insulation element, in particular the insulation felt, is elasticized by controlled compression and decompression in the direction of the surface normal of its large surfaces and a simultaneous alternating bend. For this purpose, the insulation felt is conveyed, for example, by several roller passes, which on the one hand carry out the required compression or decompression and on the other hand the mutual bending of the insulation felt. The strong compressions and the alternating bends break up firmer areas of the insulation felt, for example also inhomogeneities in the mineral fiber and / or the binder distribution, in order to achieve a uniform deformability of the insulation felt or the insulation elements made from it.

Es ist nach einem weiteren Merkmal der Erfindung vorgesehen, dass das Wandelement stiftförmige Vorsprünge aufweist, die das Dämmelement durchgreifen. Diese stiftförmigen Vorsprünge sind nagelartig ausgebildet und verlaufen parallel zur Flächennormalen des Wandelementes. Das Dämmelement wird auf die stiftförmigen Vorsprünge aufgesteckt. Durch diese Ausgestaltung wird auch sichergestellt, dass das Dämmelement in gestreckter Haltung auch bei schräg oder lotrecht angeordneten Wandelementen vollflächig an dem Wandelement anliegt. Hierbei kann auf zusätzliche Befestigungselemente, beispielsweise Kleber verzichtet wer- den, die ohnehin die Brandschutzeigenschaften einer entsprechenden Wandung nur nachteilig beeinflussen können.According to a further feature of the invention, it is provided that the wall element has pin-shaped projections which pass through the insulation element. These pin-shaped projections are nail-like and run parallel to the surface normal of the wall element. The insulation element is put on the pin-shaped projections. This configuration also ensures that the insulation element is in full contact with the wall element even when the wall elements are arranged obliquely or perpendicularly. Additional fastening elements, for example glue, can be dispensed with here, which can only adversely affect the fire protection properties of a corresponding wall anyway.

Schließlich ist nach einem weiteren Merkmal der Erfindung vorgesehen, dass auf die stiftförmigen Vorsprünge Halteteller aufgesetzt sind, die auf dem Dämmele- ment aufliegen. Mit diesen Haltetellern wird das Dämmelement auch in seiner Lage relativ zum Wandelement fixiert. Entsprechende Halteteller können beispielsweise eine zentrisch angeordnete Bohrung aufweisen, die in drei Schlitze übergeht, die in gleichmäßigen Abständen zueinander, d.h. um einen Winkel von 120° versetzt zueinander verlaufend angeordnet sind. Beispielsweise bestehen derartige Halteteller aus einer Metall- oder Kunststoffscheibe, die im Bereich der die stiftförmigen Vorsprünge aufnehmenden Bohrung ausreichend flexibel ist.Finally, according to a further feature of the invention, it is provided that holding plates are placed on the pin-shaped projections, which rest on the insulating element. With these holding plates, the insulation element is also fixed in its position relative to the wall element. Corresponding holding plates can, for example, have a centrally arranged bore which merges into three slots which are at equal distances from one another, ie at an angle of 120 ° are arranged offset to each other. For example, holding plates of this type consist of a metal or plastic disk which is sufficiently flexible in the region of the bore receiving the pin-shaped projections.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, in der eine bevorzugte Ausführungsform einer Wandung, nämlich einer Schiffswandung dargestellt ist.Further features and advantages of the invention result from the following description of the associated drawing, in which a preferred embodiment of a wall, namely a ship's wall, is shown.

Die Figur zeigt einen Abschnitt eines Schiffsrumpfes 1 mit einem Zwischendeck 2 und einer Schottwand 3, die rechtwinklig zum Zwischendeck 2 ausgerichtet ist.The figure shows a section of a ship's hull 1 with an intermediate deck 2 and a bulkhead 3, which is aligned at right angles to the intermediate deck 2.

Der Schiffsrumpf 1 , das Zwischendeck 2 und die Schottwand 3 bestehen aus Wandungen 4, die jeweils aus mehreren großflächigen Wandelementen 5 und mehreren Dämmelementen 6 zusammengesetzt sind.The ship's hull 1, the intermediate deck 2 and the bulkhead 3 consist of walls 4 which are each composed of a plurality of large-area wall elements 5 and a plurality of insulation elements 6.

Das Zwischendeck 2 hat darüber hinaus noch ein zweites Wandelement 7, welches im Abstand zum Wandelement 5 angeordnet ist, wobei zwischen den Wandelementen 5 und 7 das Dämmelement 6 angeordnet ist.The intermediate deck 2 also has a second wall element 7, which is arranged at a distance from the wall element 5, the insulation element 6 being arranged between the wall elements 5 and 7.

Jedes großflächige Wandelement 5 weist stegförmige Elemente 8 auf, die im Querschnitt rechteckförmig ausgebildet und integraler Bestandteil des Wandelementes 5 sind. Die stegförmigen Elemente 8 erstrecken sich parallel zur Flächennormalen des Wandelementes 5 und dienen der Aussteifung des Wandelementes 5.Each large-area wall element 5 has web-shaped elements 8, which are rectangular in cross section and are an integral part of the wall element 5. The web-shaped elements 8 extend parallel to the surface normal of the wall element 5 and serve to stiffen the wall element 5.

Das Dämmelement 6 besteht aus einem Dämmfilz aus Mineralfasern, nämlich aus Steinwolle, wobei das Dämmelement 6 eine Temperaturbeständigkeit von mehr als 1.000° C gemäß DIN 4102, Teil 17 aufweist.The insulation element 6 consists of an insulation felt made of mineral fibers, namely rock wool, the insulation element 6 having a temperature resistance of more than 1,000 ° C. according to DIN 4102, part 17.

Im Bereich des Schiffsrumpfes 1 und der Schottwand 3 ist eine Oberfläche 18 des Dämmelementes 6 zu erkennen, auf der ein Gittergewebe 9 angeordnet ist. Ein derartiges Gittergewebe 9 ist auch auf der zweiten großen Oberfläche, welche in der Figur nicht erkennbar ist, angeordnet. Gleiches gilt hinsichtlich des Dämmele- mentes 6, das im Bereich des Zwischendecks 2 zwischen dem Wandelement 5 und dem Wandelement 7 angeordnet ist.In the area of the ship's hull 1 and the bulkhead 3, a surface 18 of the insulation element 6 can be seen, on which a mesh 9 is arranged. Such a grid fabric 9 is also arranged on the second large surface, which cannot be seen in the figure. The same applies to the insulation mentes 6, which is arranged in the area of the false deck 2 between the wall element 5 and the wall element 7.

Das Gittergewebe 9 ist als Fasergittergewebe aus Glasfasern ausgebildet und weist eine Flexibilität auf, die die Verformbarkeit des Dämmelementes 6 nicht einschränkt, so dass das Dämmelement 6 mit den auf seinen Oberflächen 18 angeordneten Gittergeweben an die Formgebung des Wandelementes 5, beispielsweise an die gekrümmte Formgebung des Wandelementes 5 im Bereich des Schiffsrumpfes 1 angepasst werden kann. Gleichzeitig besteht die Möglichkeit, dass das Dämmelement 6 das stegförmige Element 8 übergreift. Durch die hohe Verformbarkeit des Dämmelementes 6 mit den beiden Gittergeweben 9 besteht die Möglichkeit, die Herstellung einer entsprechenden Wandung wesentlich zu vereinfachen bzw. die Kosten einer derartigen Wandung zu verringern, da ein Zuschneiden von beispielsweise steifen Dämmelementen 6 entfällt, welche in die Zwi- schenräume zwischen benachbart angeordneten stegförmigen Elementen 8 ein- gepasst werden.The mesh fabric 9 is designed as a fiber mesh fabric made of glass fibers and has a flexibility that does not restrict the deformability of the insulating element 6, so that the insulating element 6 with the mesh fabrics arranged on its surfaces 18 matches the shape of the wall element 5, for example the curved shape of the Wall element 5 in the area of the hull 1 can be adjusted. At the same time, there is the possibility that the insulating element 6 overlaps the web-shaped element 8. The high deformability of the insulation element 6 with the two lattice fabrics 9 makes it possible to significantly simplify the manufacture of a corresponding wall or to reduce the costs of such a wall, since cutting rigid insulation elements 6, for example, which does not cut into the interspaces is eliminated can be fitted between adjacent web-shaped elements 8.

Die Wandung 4 weist darüber hinaus innenseitig, d.h. im Bereich der dem Dämmelement 6 zugewandten Fläche 10 des Wandelementes 5 stiftförmige Vorsprünge 11 auf, die nagelartig ausgebildet sind und auf die das Dämmelement 6 aufsteckbar ist, um das Dämmelement 6 in seiner Lage relativ zum Wandelement 5 zu fixieren.The wall 4 also has an inside, i.e. in the area of the surface 10 of the wall element 5 facing the insulation element 5, pin-shaped projections 11 which are designed like a nail and onto which the insulation element 6 can be plugged in order to fix the insulation element 6 in its position relative to the wall element 5.

Auf die das Dämmelement 6 durchgreifenden Vorsprünge 11 sind Halteteller 12 aufgesteckt, die auf dem Dämmelement 6 in seiner montierten Position aufliegen.Holding plates 12 are placed on the protrusions 11 which pass through the insulating element 6 and rest on the insulating element 6 in its assembled position.

Das Dämmelement 6 weist eine Rohdichte von 27 kg/m3 auf und enthält einen Bindemittelgehalt von 2 Masse-%. Das als Fasergittergewebe ausgebildete Gittergewebe 9 weist quadratisch ausgebildete Maschen mit einer Kantenlänge von 10 mm auf. Die beiden Gittergewebe 9 sind mit dem Dämmelement 6 verklebt, wobei das Dämmelement 6 mit dem Gittergewebe 9 eine über seine Länge, Breite und Höhe gleichbleibende Verformbarkeit aufweist, so dass das Dämmelement 6 nicht orientierungsgebunden eingebaut werden muß. The insulation element 6 has a bulk density of 27 kg / m 3 and contains a binder content of 2% by mass. The mesh fabric 9, which is designed as a fiber mesh fabric, has square meshes with an edge length of 10 mm. The two lattice fabrics 9 are glued to the insulation element 6, the insulation element 6 with the lattice fabric 9 having a deformability which is constant over its length, width and height, so that the insulation element 6 does not have to be installed oriented.
