Description

Beschreibung  description
Sandwichpaneel sandwich
Die vorliegende Erfindung betrifft ein Sandwichpaneel gemäß dem Oberbegriff des Anspruchs 1 . The present invention relates to a sandwich panel according to the preamble of claim 1.
Entsprechende Sandwichpaneels sind bereits in den beiden nachveröffentlichten Dokumenten DE 10 2009 036 582 sowie DE 10 2009 036 583 beschrieben. Corresponding sandwich panels are already described in the two post-published documents DE 10 2009 036 582 and DE 10 2009 036 583.
Insbesondere sind die Sandwichpaneels als Fertigelemente für ein kostengünstig aufzustellendes Haus vorgesehen. In particular, the sandwich panels are provided as prefabricated elements for a house to be installed cost-effectively.
Herkömmlicherweise werden solche Sandwichpaneels beim Aufbau einer flächenhaften Konstruktion, wie beispielsweise einer Wandkonstruktion über Verbindungsprofile an den Stirnseiten miteinander gekoppelt. Insbesondere auch bei den Eckverbindungen, also bei einer Erstellung einer Wandecke, beispielsweise im 90°-Winkel, werden solche Verbindungsprofile (hier: Eckverbindungsprofile) verwendet. Conventionally, such sandwich panels are coupled together in the construction of a planar construction, such as a wall construction via connecting profiles on the front sides. In particular, in the corner joints, ie when creating a wall corner, for example, in the 90 ° angle, such connection profiles (in this case: Eckverbindungsprofile) are used.
Nachteilig an der Verwendung solcher Verbindungsprofile ist jedoch die Erhöhung der für den Aufbau einer Wand notwendigen Konstruktionselemente, was die Kosten erhöht und die Logistik wie auch die Komplexität erhöht. A disadvantage of the use of such connection profiles, however, is the increase in the construction elements necessary for the construction of a wall, which increases the cost and increases the logistics as well as the complexity.
Aufgabe der vorliegenden Erfindung ist es, flächenförmige Gebilde, z.B. Wände oder Decken, aus den vorgenannten Sandwichpaneels sowohl im 180°- wie auch im 90°-Winkel ohne zusätzliche Verbindungsprofile herstellen und aufbauen zu können. Insbesondere soll es möglich sein, aus den Sandwichpaneels Wände für ein Haus herstellen zu können, wobei eine möglichst geringe Anzahl verschiedener Bauteile verwendet und auf ein Rahmensystem, in das die Sandwichpaneels eingehängt oder montiert werden, verzichtet werden kann. The object of the present invention is to be able to produce and construct sheet-like structures, for example walls or ceilings, from the abovementioned sandwich panels both at 180 ° and at 90 ° without additional connecting profiles. In particular, it should be possible to produce from the sandwich panel walls for a house, with the smallest possible number of different Used components and on a frame system in which the sandwich panels are mounted or mounted, can be dispensed with.
Diese Aufgabe wird durch die im Anspruch 1 genannten Merkmale gelöst. This object is achieved by the features mentioned in claim 1.
Demgemäß werden bei Sandwichpaneels der eingangs genannten Art die Stirnseiten an zwei gegenüberliegenden und zueinander parallelen Längsseiten derart abgeschrägt oder gestuft ausgebildet, dass (i) zwei um 90° zueinander gedrehte Sandwichpaneels an der Stirnseite formschlüssig zusammengefügt werden können und dabei eine 90°-Ecke ausbilden und (ii) ein um 180° gedrehtes Sandwichpaneel mit einem anderen nicht gedrehten Sandwichpaneel zur Realisierung einer 180°-Verbindung formschlüssig aneinander anschließen. Auf diese Art und Weise können ohne zusätzliche Profile, Rahmen oder sonstige Verbindungselemente Wände und Eckverbindungen im 90°-Winkel gebildet werden. Dabei können die Stirnseiten nicht nur einfach sondern auch mehrfach abgestuft oder in anderer geeigneter Weise ausgebildet sein. Accordingly, in sandwich panels of the type mentioned above, the end faces are bevelled or stepped on two opposite and mutually parallel longitudinal sides in such a manner that (i) two sandwich panels rotated by 90 ° relative to one another can be positively joined to form a 90 ° corner and (ii) a sandwich panel rotated by 180 ° with another non-rotated sandwich panel to form-fit together to realize a 180 ° connection. In this way, walls and corner joints can be formed at 90 ° angle without additional profiles, frames or other fasteners. In this case, the end faces can not only be simple but also multi-stepped or formed in another suitable manner.
Ist die Stirnseite einfach abgestuft, so sind vorzugsweise alle Flächen der Stufung mit gleicher Breite gewählt, da dann ein vollständiges Aneinanderliegen der einander zugewandten Flächen benachbarter Stirnseiten von zwei zusammenzufügenden Sandwichpaneels aufeinander zu liegen kommen. If the end face is simply stepped, then preferably all surfaces of the grading are selected with the same width, since then a complete juxtaposition of the mutually facing surfaces of adjacent end faces of two sandwich panels to be joined together come to rest on one another.
Die Stirnseite kann auch durch Einbringen eines zusätzlichen Profils in die Sandwichpaneels erzeugt werden. The front side can also be created by introducing an additional profile into the sandwich panel.
Sowohl bei der abgeschrägten wie auch bei der gestuften Version der Stirnseiten ist es möglich, zwei benachbarte Sandwichpaneel durch Schraubverbindungen, Kleben, Nieten, etc. miteinander zu fixieren, egal ob die Verbindung eine 180°- oder eine 90°-Verbindung ist. Both in the tapered version and in the stepped version of the end faces, it is possible to fix two adjacent sandwich panels together by screw connections, gluing, riveting, etc., regardless of whether the connection is a 180 ° or a 90 ° connection.
Gemäß einer besonders bevorzugten Ausführungsform sind die Flächen der Stirnseiten mit ein oder mehreren Dichtvorrichtungen, beispielsweise Dichtraupen, die sich über deren gesamte Länge erstrecken, versehen, so dass eine Feuchtigkeits- und Winddichtekopplung von zwei benachbarten Sandwichpaneels hergestellt werden kann. Diese Dichtvorrichtungen können auch zumindest teilweise in Nuten aufgenommen sein oder bereits in die Stirnseiten integriert sein, falls die Stirnseiten beispielsweise aus einem extrudierten Profil bestehen. According to a particularly preferred embodiment, the surfaces of the end faces are provided with one or more sealing devices, for example sealing beads, which extend over their entire length, so that a Moisture and windproof coupling of two adjacent sandwich panels can be made. These sealing devices may also be at least partially received in grooves or already integrated in the end faces, if the end faces, for example, consist of an extruded profile.
Gemäß einer weiteren vorzugsweisen Ausführungsform sind die Sandwichpaneels standardisiert in einer festgelegten Anzahl von Längen, beispielsweise drei Längen ausgebildet, mit denen sich Wände mit und ohne Tür- und Fensteröffnungen mit nur sehr wenig unterschiedlichen Elementen bilden lassen. According to another preferred embodiment, the sandwich panels are standardized in a fixed number of lengths, for example, three lengths formed with which can form walls with and without door and window openings with only very few different elements.
Die Deckschichten können dabei aus Stahl, Aluminium, Kunststoff oder Kunststoffcompound oder Holzmaterial bestehen oder diese Materialien enthalten. Der Sandwichkern kann beispielsweise aus einem zur Steifigkeit der Konstruktion beitragenden Dämmmaterial, beispielsweise Polyurethan, Polystyrol oder Mineralwolle bestehen. The cover layers may consist of steel, aluminum, plastic or plastic compound or wood material or contain these materials. The sandwich core, for example, consist of a contributing to the rigidity of the construction insulation material, such as polyurethane, polystyrene or mineral wool.
Gemäß einer besonders bevorzugten Ausführungsform ist eine oder sind beide Stirnflächen eines Sandwichpaneels durch entsprechende Umformung einer oder beider Deckenschichten ausgebildet, so dass jede Stirnflächen integral mit einer Deckschicht ausgebildet ist. According to a particularly preferred embodiment, one or both end faces of a sandwich panel are formed by corresponding deformation of one or both ceiling layers, so that each end face is formed integrally with a cover layer.
Die Deckschichten können auf unterschiedlichste Weise miteinander verbunden sein. Einerseits ist es möglich, dass sie durch den Sandwichkern miteinander verbunden, beispielsweise verklebt, sind. Weiter ist es möglich, dass die Deckschichten unmittelbar miteinander verbunden sind, beispielsweise durch eine entsprechende Falzung, durch Nieten oder auch durch eine clipsende Verrastung, welche unmittelbar oder unter Zwischenschaltung eines separaten Elements erreicht werden kann. The cover layers can be connected to each other in a variety of ways. On the one hand, it is possible that they are interconnected by the sandwich core, for example, glued, are. Further, it is possible that the cover layers are directly connected to each other, for example by a corresponding fold, by riveting or by a clip-locking, which can be achieved directly or with the interposition of a separate element.
Die Erfindung wird nachfolgend anhand eines konkreten Ausführungsbeispiels und mit Bezug auf die beigefügten Zeichnungen näher erläutert. Die Zeichnungen zeigen in Figur 1 eine schematische Querschnittsdarstellung eines erfindungsgemäßen Sandwichpaneels, The invention will be explained in more detail below with reference to a specific embodiment and with reference to the accompanying drawings.

Wand mit standardisierten Sandwichpaneels.  Wall with standardized sandwich panels.
Das in Figur 1 im Querschnitt schematisch dargestellte Sandwichpaneel besteht im wesentlichen aus einer ersten Deckschicht 12, einer zweiten Deckschicht und einem Sandwichkern 1 16. Die erste Deckschicht 12 erstreckt sich ebenfalls über die beiden Stirnbereiche 20, wobei es entsprechend umgeformt ist und bildet diese mit. Die zweite Deckschicht 14 ist im wesentlichen parallel zur ersten Deckschicht 12 angeordnet und weist an deren Längsseiten Falzungen auf, mittels denen die beiden Deckschichten 12 und 14 in diesen Falzbereichen miteinander verbunden sind, um eine einheitliche und gegenüber dem Innenraum abgeschlossene Außenhaut herzustellen. Der so hergestellte Innenraum ist mit einem als Sandwichkern dienenden Schaummaterial 16 aus Polyurethanmaterial ausgeschäumt. Natürlich können jederzeit auch andere Kernmaterialien verwendet werden. The sandwich panel shown schematically in cross-section in Figure 1 consists essentially of a first cover layer 12, a second cover layer and a sandwich core 1 16. The first cover layer 12 also extends over the two end portions 20, wherein it is correspondingly formed and forms this with. The second cover layer 14 is arranged substantially parallel to the first cover layer 12 and has folds on its longitudinal sides, by means of which the both cover layers 12 and 14 are connected to one another in these fold regions in order to produce a uniform outer skin that is closed relative to the inner space. The interior thus produced is foamed with a polyurethane foam material 16 serving as a sandwich core. Of course, other core materials can be used at any time.
Natürlich können die Deckschichten 12 und 14 auch auf andere Weise miteinander verbunden werden, beispielsweise über separate Elemente aus Blech, Kunststoff oder Holz. Of course, the cover layers 12 and 14 can be connected to each other in other ways, for example via separate elements made of sheet metal, plastic or wood.
Bei der Herstellung ist es insbesondere möglich, solche Sandwichpaneels in einer Doppelbandanlage herzustellen, wobei die Materialien für die Deckschichten 12 und 14 umgeformt oder als Stangenmaterial der Doppelbandanlage zugeführt und das Kernmaterial vor dem Einlauf in die Doppelbandanlage eingeführt wird. In the production, it is in particular possible to produce such sandwich panels in a double-belt system, wherein the materials for the cover layers 12 and 14 formed or fed as a rod material of the double belt system and the core material is introduced before entering the double belt system.
Die beiden Stirnseiten 20 des Sandwichpaneels 10 sind bei der Ausführungsform in Figur 1 in einfach abgestufter Form ausgebildet, wobei in Höhe der halben Dicke h3 des Sandwichpaneels 10 eine Nase vorspringt. Dabei ist sowohl die Breite des Vorsprungs h2 wie auch die Höhe des Vorsprungs h3 genauso groß wie die verbleibende Höhe des hinter die Nase zurückspringenden Teils h-ι, so dass sich in der Querschnittsdarstellung in Fig. 1 eine Treppenform ergibt. The two end faces 20 of the sandwich panel 10 are formed in the embodiment in Figure 1 in a simple stepped form, wherein at the height of half the thickness h 3 of the sandwich panel 10 projects a nose. In this case, both the width of the projection h 2 as well as the height of the projection h 3 is the same size as the remaining height of the part jumping behind the nose h-ι, so that in the cross-sectional view in Fig. 1 results in a staircase shape.
Die so ausgebildete Stufung ist geeignet, um ein formschlüssiges Zusammenfügen von zwei Sandwichpaneels 10 an ihren sich über die Längsseite erstreckenden Stirnseiten zu ermöglichen, und zwar auf zweierlei Arten. Fügt man zwei Sandwichpaneels zusammen, die um 90° gedreht sind, so wie in Fig. 2 dargestellt, so ergibt sich eine 90°-Eckverbindung (Bezugszeichen 22) wobei die Fläche hi eines Sandwichpaneels auf der Fläche h2 des benachbarten Sandwichpaneels zu liegen kommt und in gleicher Weise die Fläche h2 des ersten Sandwichpaneels auf der Fläche h3 des zweiten Sandwichpaneels zu liegen kommt. Ordnet man die Sandwichpaneels in einer Weise an, dass jedes benachbarte Sandwichpaneel um 180° gedreht ist, so kann man, wie dies in Figur 3 dargestellt ist, ein insgesamt ebenes flächiges Gebilde in Form einer Wand realisieren, Mit anderen Worten kommt zwischen zwei benachbarten Sandwichpaneels jeweils eine 180°-Verbindung zustande. Dabei kommt jeweils die Nase einer Stufung in die durch den Rücksprung gebildete Ausnehmung des jeweils anschließenden Sandwichpaneels zu liegen. The graduation formed in this way is suitable for enabling a positive joining of two sandwich panels 10 at their end faces extending over the longitudinal side, in two ways. Assembling two sandwich panels, which are rotated by 90 °, as shown in Fig. 2, this results in a 90 ° corner connection (reference numeral 22) wherein the surface hi of a sandwich panel comes to rest on the surface h 2 of the adjacent sandwich panel and in the same way the surface h 2 of the first sandwich panel comes to lie on the surface h 3 of the second sandwich panel. If the sandwich panels are arranged in such a way that each adjacent sandwich panel is rotated by 180 °, then, as shown in FIG. 3, it is possible to realize an overall flat planar structure in the form of a wall. In other words, between two adjacent sandwich panels in each case a 180 ° connection. In each case, the nose of a gradation comes to lie in the recess formed by the recess of the respective subsequent sandwich panel.
In den Figuren 4 und 5 sind ähnliche Abbildungen wie in den Figuren 2 bzw. 3 gezeigt, wobei nunmehr jedoch durch Verschraubungen 26 sowohl die Eckverbindungen (Figur 4) wie auch die 180°-Verbindungen (Figur 5) realisiert werden können. Anstelle der Verschraubung ist es natürlich auch möglich Klebe-, Niet- oder sonstige Verbindungen zu wählen. Es ist lediglich notwendig, benachbarte Sandwichpaneels entsprechend miteinander zu fixieren. FIGS. 4 and 5 show similar illustrations as in FIGS. 2 and 3, wherein, however, by means of screw connections 26 both the corner connections (FIG. 4) and the 180 ° connections (FIG. 5) can now be realized. Of course, instead of the screw connection, it is also possible to choose glued, riveted or other connections. It is only necessary to fix adjacent sandwich panels according to each other.
In Figur 6 ist die Anordnung verschiedener Dichtraupen dargestellt. Dabei sind in den Bereich der Kontaktflächen an jeder Stirnseite eines Sandwichpaneels vorliegend jeweils zwei Dichtraupen vorgesehen, die sich beim Zusammenfügen ergänzen. Beim Zusammenfügen von benachbarten Sandwichpaneels in der 90°- Anordnung oder der 180°-Anordnung kommen diese Dichtanordnungen, beispielsweise Dichtraupen, zwischen benachbarten Flächen zu liegen und ergeben einen feuchtigkeits- und luftdichten Abschluss. Nicht dargestellt ist, dass diese Dichtraupen auch in Ausnehmungen (z.B. Nuten) teilweise aufgenommen sein können. FIG. 6 shows the arrangement of different sealing beads. In each case two sealing beads are provided in the area of the contact surfaces on each end face of a sandwich panel, which complement each other during assembly. When joining adjacent sandwich panels in the 90 ° arrangement or the 180 ° arrangement, these sealing arrangements, for example sealing beads, come to lie between adjacent areas and result in a moisture-proof and hermetic seal. It is not shown that these sealing beads can also be partially received in recesses (for example grooves).
In Figur 7 ist zu erkennen, wie mit den in den vorhergehenden Figuren vorgestellten Sandwichpaneels ein Raum gebildet werden kann. So besteht der in Figur 7 dargestellte Raum aus zwei gegenüberliegenden Längs- und zwei gegenüberliegenden Querwänden, wobei die Längswände aus 5 jeweils in umgekehrter Orientierung benachbarten Paneels 30.1 bzw. 30.3 bestehen und die Querwände ebenfalls aus jeweils drei in umgekehrter Orientierung zueinander angeordneten Längspaneel 30.2 bzw. 30.4 bestehen. Lediglich die jeweils äußeren Paneel 30.1 mit 30.2, 30.2 mit 30.3, 30.3 mit 30.4 und 30.4 mit 30.1 ergeben die 90°-Eckverbindungen. Auf diese Weise ist klar, dass ein Haus in einem Rastermaß aufgebaut werden kann. In FIG. 7 it can be seen how a space can be formed with the sandwich panels presented in the preceding figures. Thus, the space shown in Figure 7 consists of two opposite longitudinal and two opposite transverse walls, wherein the longitudinal walls of 5 respectively in the opposite direction adjacent panel 30.1 and 30.3 consist and the transverse walls also from three each in reverse orientation to each other arranged longitudinal panel 30.2 or. 30.4 exist. Only the respective outer panel 30.1 with 30.2, 30.2 with 30.3, 30.3 with 30.4 and 30.4 with 30.1 give the 90 ° -Eckverbindungen. In this way, it is clear that a house can be built in a grid.
Verwendet man standardisierte Sandwichpaneels mit beispielsweise drei Längen, so kann man damit in einfachster Art und Weise Wände mit oder ohne Fenster- und Türöffnungen bilden, ohne dass ein nachträgliches Bearbeiten notwendig ist oder Abfallprodukte auftreten. Dies ist in Figur 8 dargestellt. So werden bei dem Wandaufbau in Figur 8 Standardpaneels mit einer ersten Länge L1 (Bezugszeichen 23), mit einer Länge L2 (Bezugszeichen 34) und mit einer Länge L3 (Bezugszeichen 36) verwendet. Werden zwei Sandwichpaneels mit der Länge L1 zusammengefügt, so ergibt sich eine geschlossene Wand. Wird zwischen zwei Paneels mit der Länge L1 lediglich ein Paneel mit der Länge L3 eingefügt, die oben angeordnet ist, so ergibt sich die Türöffnung wie in Figur 8 zu erkennen. Werden zwischen zwei Sandwichpaneels mit der Länge L1 oben ein Paneel mit der Länge L3 und unten ein Paneel mit der Länge L2 eingeführt, so ergibt sich eine Fensteröffnung, wie ebenfalls in Figur 8 zu erkennen. If standardized sandwich panels with, for example, three lengths are used, it is thus possible in the simplest manner to form walls with or without window and door openings without subsequent processing being necessary or waste products occurring. This is shown in FIG. Thus, in the wall construction in FIG. 8, standard panels having a first length L1 (reference numeral 23), a length L2 (reference numeral 34) and a length L3 (reference numeral 36) are used. If two sandwich panels of length L1 are joined, the result is a closed wall. If only one panel with the length L3, which is arranged at the top, is inserted between two panels with the length L1, then the door opening results as can be seen in FIG. If a panel with the length L3 is inserted between two sandwich panels with the length L1 at the top and a panel with the length L2 is inserted at the bottom, the result is a window opening, as can also be seen in FIG.
Auf diese Art und Weise ergibt sich ein Schnellbausystem zur Errichtung von low- cost-Häusern. Dabei ist eine kostengünstige, weil kontinuierliche Herstellung der einzelnen Sandwichpaneels möglich. Auch lassen sich bei gleicher Konstruktion die verschiedensten Materialien für die Paneels verwenden, so kann die Deckschicht aus Stahl, Aluminium, Kunststoff oder Holz bestehen; die Kernschicht kann als Isolationsschicht beispielsweise aus Polyurethan, mit Feststoffen und/oder Recyclingmaterial gefülltem Polyurethan oder Polystyrol gebildet sein. Natürlich können auch Materialen wie Mineralwolle, etc. verwendet werden. Insgesamt ergibt sich durch die Konstruktion der mögliche Aufbau ohne Verbindungselemente in 180°- oder 90°-Weise. In this way, a quick-build system for the construction of low-cost houses. In this case, a cost-effective, because continuous production of the individual Sandwichpaneels possible. Also can be used with the same construction, the most diverse materials for the panel, the cover layer of steel, aluminum, plastic or wood can be made; The core layer may be formed as an insulating layer, for example, polyurethane, filled with solids and / or recycled material polyurethane or polystyrene. Of course, materials such as mineral wool, etc. can be used. Overall, the construction results in the possible construction without connecting elements in a 180 ° or 90 ° manner.
Mit solchen Sandwichpaneels ist es möglich, mit einer möglichst geringen Anzahl unterschiedlicher Konstruktionselemente ein kostengünstiges Haus, möglichst unter Verzicht auf gesonderte Rahmensysteme, herzustellen. Die Statik des Gebäudes soll durch das Design der Sandwichpaneels, eine Verklebung der Deckschichten, den Sandwichkern und die Verbindung der Sandwichpaneels untereinander erbracht werden. Falls notwendig, können am Boden Profile (U- oder T-Profile) angeordnet werden in die die Sandwichpaneel zur Ausbildung einer Wand eingesteckt werden. Dies sichert einen guten Halt. In gleicher Weise kann ein Ringanker am oberen Wandabschluss ebenfalls durch ein Profil realisiert werden. Natürlich ist es auch möglich, mit den erfindungsgemäßen Sandwichpaneels nicht nur Wände, sondern auch Decken eines Hauses auszubilden. With such sandwich panels, it is possible to produce a cost-effective house with the smallest possible number of different structural elements, preferably with no need for separate frame systems. The statics of the building is due to the design of the sandwich panels, a bonding of the outer layers, the sandwich core and the connection of the sandwich panel with each other be provided. If necessary, profiles (U- or T-profiles) can be placed on the floor into which the sandwich panel can be inserted to form a wall. This ensures a good grip. In the same way, a ring anchor on the upper wall termination can also be realized by a profile. Of course, it is also possible to form not only walls, but also ceilings of a house with the sandwich panel according to the invention.
