Description

"Profilelement mit zugfesten Fasern""Profile element with tensile fibers"
Die Erfindung betrifft ein Profilelement nach dem Oberbegriff des Anspruchs 1.The invention relates to a profile element according to the preamble of claim 1.
Derartige Profilelemente sind aus der Praxis vielfach in Form von Kunststoff-Hohlkammerprofilen bekannt. Um eine ausrei- chende Biegesteifigkeit der Profilelemente zu gewährleisten ist es bekannt, in die Hohlkammem des Profils metallische Verstärkungsprofile einzuschieben. Dadurch ist eine ausreichende Biegesteifigkeit erzielbar.Such profile elements are widely known in practice in the form of plastic hollow chamber profiles. In order to ensure sufficient bending rigidity of the profile elements, it is known to insert metallic reinforcement profiles into the hollow chambers of the profile. Adequate bending stiffness can thereby be achieved.
Jedoch ist nachteilig, dass die metallischen Verstärkungsprofile eine Kälte- bzw. Wärmebrücke darstellen, so dass die thermische Isolierwirkung des Profilelementes beeinträchtigt werden kann und / oder ein erhöhter zusätzlicher Aufwand erforderlich ist, um die gewünschte thermische Isolierwirkung des Profilele- mentes zu erzielen bzw. wieder herzustellen. Zudem ist bei derHowever, it is disadvantageous that the metallic reinforcement profiles represent a cold or thermal bridge, so that the thermal insulating effect of the profile element can be impaired and / or an increased additional effort is required to achieve or again the desired thermal insulating effect of the profile element manufacture. In addition, the
Verarbeitung der Profilelemente nachteilig, dass die eingeschobenen metallischen Verstärkungsprofile teurere und standfestere Werkzeuge, beispielsweise Sägeblätter, erfordern als für die reine Kunststoffbearbeitung. Das Fertigungsverfahren ist zudem aufwendig, da die metallischen Verstärkungsprofile in separatenProcessing of the profile elements disadvantageous that the inserted metallic reinforcement profiles require more expensive and more stable tools, such as saw blades, than for pure plastic processing. The manufacturing process is also complex because the metallic reinforcement profiles in separate
Bearbeitungsschritten, unabhängig von den Kunststoffprofilen, abgelängt werden. Da die Kunststoffprofile an den Ecken des zu bildenden Rahmens miteinander verschweißt werden und das metallische Verstärkungsprofil dort stören würde, ist das Verstärkungsprofil kürzer zu bemessen als das Kunststoffprofil, und des muß genau positioniert werden, damit es den Eck-Ver- schweißungsvorgang nicht beeinträchtigt.Processing steps, regardless of the plastic profiles, be cut to length. Since the plastic profiles are welded together at the corners of the frame to be formed and would interfere with the metallic reinforcement profile there, the reinforcement profile must be dimensioned shorter than the plastic profile and this must be positioned precisely so that it does not interfere with the corner welding process.
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Profilelement dahingehend zu verbessern, dass dieses bei Er- zielung einer hohen Biegesteifigkeit frei von Kältebrücken ist und eine möglichst einfache Bearbeitbarkeit ermöglicht.The invention is based on the object of improving a generic profile element to the effect that it is free of cold bridges when achieving a high bending stiffness and enables the easiest possible workability.
Diese Aufgabe wird durch ein Profilelement mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a profile element with the features of claim 1.
Die Erfindung schlägt mit anderen Worten vor, statt der Verwendung von metallischen Verstärkungsprofilen zugfeste Fasern einzusetzen, die in Längsrichtung des Profilelementes zugfest sind. Bei der Biegebeanspruchung wird ein Teil des Profilele- mentes auf Druck und ein anderer Teil des Profilelementes aufIn other words, the invention proposes, instead of using metallic reinforcement profiles, to use tensile fibers which are tensile in the longitudinal direction of the profile element. During the bending stress, part of the profile element is pressed and another part of the profile element
Zug beansprucht. Dazwischen befindet sich eine neutrale Zone. Dadurch, dass die zugfesten Fasern im Abstand von dieser neutralen Zone angeordnet werden, bewirken sie eine Aussteifung des Profils.Train claimed. In between there is a neutral zone. By placing the tensile fibers at a distance from this neutral zone, they stiffen the profile.
Je nachdem, gegenüber welcher Biegerichtung das Profilelement ausgesteift werden soll, ist die Anordnung der Fasern innerhalb des Profilelementes zu wählen. So können beispielsweise in dem Profilelement zwei Stränge von Fasern vorgesehen sein, die auf zwei gegenüberliegenden Seiten von den neutralenDepending on the direction in which the profile element is to be braced, the arrangement of the fibers within the profile element must be selected. For example, two strands of fibers can be provided in the profile element, those on two opposite sides of the neutral
Fasen des Profilelementes vorgesehen sind, sodass eine Biegesteifigkeit gegenüber der Biegebeanspruchung in zwei Richtungen erzielt wird. Gegebenenfalls kann jedoch nur ein einziger Strang zugfester Fasern vorgesehen sein, wobei durch den Ver- bund, den das Profilelement mit mehreren anderen Profilelemente zu einem gesamten Tür- oder Fensterrahmen bildet, eine ausreichende Gesamtsteifigkeit dieses Rahmens gegenüber der vergleichsweise geringen Einzelsteifigkeit des einzelnen Profilelementes erzielt werden.Chamfers of the profile element are provided so that a bending stiffness in relation to the bending stress is achieved in two directions. If necessary, however, only a single strand of tensile fibers can be provided, one being formed by the composite which the profile element forms with a number of other profile elements to form an entire door or window frame sufficient overall rigidity of this frame compared to the comparatively low individual rigidity of the individual profile element can be achieved.
Vorzugsweise können die Fasern im vorgespannten Zustand in dem Profilelement angeordnet werden. In derartigen Fällen sind, von der neutralen Faser des Profilelementes aus gesehen, stets zwei Faserstränge dieser zugfesten Fasern an zwei gegenüberliegenden Stellen des Profilelementes vorzusehen, damit nach Einbringen dieser zugfesten Fasern das Profilelement nicht verformt wird, sondern sich die Vorspannungen der beiden Faserstränge neutralisieren.The fibers can preferably be arranged in the profile element in the prestressed state. In such cases, as seen from the neutral fiber of the profile element, two fiber strands of these tensile fibers must always be provided at two opposite locations of the profile element, so that after the introduction of these tensile fibers, the profile element is not deformed, but the prestresses of the two fiber strands are neutralized.
Eine besonders zugfeste Verbindung zwischen den Fasern und dem Profilelement kann dadaurch erzielt werden, dass die Fasern gemeinsam mit dem Kunststoff extrudiert werden, oder sie kann durch eine Verklebung oder Verschweißung der Fasern mit dem Kunststoff erfolgen. Gegebenenfalls kann vorgesehen sein, die Fasern zwischen zwei Platten oder zwischen zwei Streben des Hohlkammerprofils anzuordnen und dann diese beiden Platten miteinander zu verkleben oder zu verschweißen, sodass die zugfesten Fasern sicher und gegebenenfalls ihre Vorspannung beibehaltend festgelegt werden können. Eine Verschweißung kann mit den hierzu dem Fachmann geläufigen Mitteln bewirkt werden, beispielsweise unter Verwendung von Zusatzwerkstoffen oder zusatzfrei, beispielsweise durch Ultraschallverschwei- ßung oder dergleichen.A particularly tensile connection between the fibers and the profile element can be achieved by extruding the fibers together with the plastic, or it can be achieved by gluing or welding the fibers to the plastic. If appropriate, provision can be made to arrange the fibers between two plates or between two struts of the hollow chamber profile and then to glue or weld these two plates to one another, so that the tensile fibers can be fixed securely and, if necessary, maintaining their pretension. Welding can be effected with the means known to the person skilled in the art, for example using filler materials or without additives, for example by ultrasonic welding or the like.
Die Fasern können unmittelbar mit einem Abschnitt des Hohl- kammerprofils verbunden werden. Gegebenenfalls kann hierbei jedoch das Problem einer schlechten Erreichbarkeit auftreten, insbesondere dann, wenn die Fasern in einem vorgespannten Zustand in dem Profilelement angeordnet werden sollen. Daher kann vorteilhaft eine einfachere Einbringung der Fasern an ei- nem separaten Bauteil vorgesehen werden, welches dann zurThe fibers can be connected directly to a section of the hollow chamber profile. If necessary, however, the problem of poor accessibility can occur, in particular if the fibers are to be arranged in the profile element in a prestressed state. Therefore, a simpler introduction of the fibers can advantageously be provided on a separate component which is then used for
Vervollständigung des Profilementes mit anderen Bauteilen ver- bunden wird. Beispielsweise kann das separate Bauteil als Kern ausgestaltet sein, welcher anstelle der metallischen Verstärkung in das übrige, hüllrohrartige Bauteil eingeschoben wird, um so insgesamt das Profilelement zu schaffen.Completion of the profile element with other components is bound. For example, the separate component can be designed as a core, which is inserted into the rest of the cladding tube-like component instead of the metallic reinforcement, so as to create the overall profile element.
Bei Verwendung eines derartigen Kerns kann dieser vorzugsweise aus einer Leichtbaustruktur bestehen, beispielsweise durch dreidimensional strukturierte Platten oder durch Verwendung von geschäumten Werkstoffen. Diese Leichtbaustruktur- elemente können insbesondere durch die zusätzlich vorgesehenen zugfesten Fasern eine hohe mechanische Stabilität aufweisen, insbesondere eine hohe Biegesteifigkeit, und sie können aufgrund von Hohlräumen die thermische Isolierwirkung des Türbzw. Fensterrahmens positiv beeinflussen.If such a core is used, it can preferably consist of a lightweight structure, for example by three-dimensionally structured plates or by using foamed materials. These lightweight structural elements can have a high mechanical stability, in particular a high flexural strength, in particular due to the additionally provided tensile fibers, and they can, due to cavities, the thermal insulating effect of the door or. Influence window frames positively.
Aufgrund der hohen Biegesteifigkeit, die sich durch die Verwendung zugfester Fasern, insbesondere vorgespannter Fasern, erzielen lässt, kann die Verwendung von Rezyklat für den Kern vorgesehen werden, sodass die Abfall- und Verschnittmengen, die in einem Herstellungsbetrieb von Profilelementen ohnehin anfallen, problemlos dafür genutzt werden können, Kerne herzustellen, mit deren Hilfe die Hohlkammer-Profilelemente ausgesteift werden können.Due to the high bending stiffness that can be achieved through the use of tensile fibers, especially prestressed fibers, the use of recycled material can be provided for the core, so that the waste and waste quantities that occur in a profile element manufacturing plant can be used without any problems be able to produce cores with the help of which the hollow chamber profile elements can be stiffened.
Als zugfeste Fasern kommen vorzugsweise unidirektional ausgerichtete Monofilamente in Frage, so dass bei möglichst geringem Materialeinsatz und Platzbedarf eine möglichst hohe Zugfestigkeit erzielt wird. Als Material kommt beispielsweise Glasfasern oder Karbonfasern, gegebenenfalls auch metallische Fa- sern in Frage. Insbesondere bei der Verwendung von Glasfasern und Karbonfasern jedoch ist vorteilhaft, dass diese mit den üblichen, zur Kunststoffbearbeitung geeigneten Werkzeugen bearbeitet werden können, beispielsweise zur Ablängung der einzelnen Profilelemente gesägt werden können. Auch bei einer späteren Aufbereitung des Profilelementes stören die Glas- oderUnidirectionally oriented monofilaments are preferred as tensile fibers, so that the highest possible tensile strength is achieved with the least possible use of material and space requirements. For example, glass fibers or carbon fibers, and possibly also metallic fibers, are suitable as the material. However, in particular when using glass fibers and carbon fibers, it is advantageous that they can be processed with the usual tools suitable for plastics processing, for example for sawing to length the individual profile elements. Even when the profile element is reprocessed later, the glass or

Wenn die zugfesten Fasern in einem separat vom übrigen Hohlkammerprofil hergestellten Kern vorgesehen sind, kann vorzugsweise eine besonders enge, passgenaue Verbindung zwi- sehen diesem äußeren Hohlkammerprofil und dem Kern vorgesehen sein, um eine möglichst hohe Biegestabilität des Profilelementes zu gewährleisten.Not carbon fibers. If the tensile fibers are provided in a core produced separately from the rest of the hollow chamber profile, a particularly close, precisely fitting connection can preferably be provided between this outer hollow chamber profile and the core in order to ensure the highest possible bending stability of the profile element.
Abweichend von der vorerwähnten Anwendung bei Tür- oder Fensterprofilen können auch flächige Gegenstände wie beispielsweise Platten durch zugfeste Fasern mit einer sehr hohen Biegesteifigkeit versehen werden. So können beispielsweise Leichtbauplatten beiderseitig mit derartig zugfesten Fasern kaschiert werden, wobei je nach Verwendungszweck der Platte die Biegesteifigkeit in der gewünschten Plattenrichtung verstärkt werden kann. Gegebenenfalls können die Fasern in mehreren Richtungen aufgebracht werden und dementsprechend eine Durchbiegung der Platte in verschiedenen Richtungen zu erschweren bzw. zu verhindern.Deviating from the above-mentioned application for door or window profiles, even flat objects such as panels can be provided with a very high bending stiffness by means of tensile fibers. For example, lightweight panels can be laminated on both sides with such tensile fibers, and depending on the intended use of the panel, the bending stiffness in the desired panel direction can be increased. If necessary, the fibers can be applied in several directions and accordingly complicate or prevent deflection of the plate in different directions.
Es kann vorgesehen sein, jeweils unidirektionale Fasern zu verwenden und diese stets nur in einer Richtung mit dem zu verstärkenden Bauelement zu verbinden, wie beispielsweise einer Platte oder einem stangenartigen Bauteil wie einem Profilele- ment. Dabei werden die vorgespannten Fasern vorzugsweise gleichzeitig an zwei Seiten dieses Bauelementes befestigt, welche sich hinsichtlich der neutralen Faser gegenüberliegen, um eine Verformung des Bauelementes zuverlässig auszuschließen, wenn nach dem Aufbringen der Fasern das Bauelement entlas- tet wird und die vorgespannten Fasern sich ansonsten unterProvision can be made to use unidirectional fibers in each case and always to connect them to the component to be reinforced in only one direction, for example a plate or a rod-like component such as a profile element. In this case, the prestressed fibers are preferably fastened simultaneously on two sides of this component, which lie opposite one another with respect to the neutral fiber, in order to reliably preclude deformation of the component if the component is relieved after the fibers have been applied and the prestressed fibers are otherwise underneath

Gegebenenfalls können nacheinander Fasern in verschiedenen Richtungen auf das Bauelement aufgebracht werden, um so die Biegesteifigkeit des Bauelementes gegenüber verschiedenenIf necessary, fibers can be applied to the component in different directions one after the other, so as to make the component more rigid in relation to different ones

Ein Einsatz von stangenartigen Bauelementen, die gemäß dem vorliegenden Vorschlag faserverstärkt sind, kann außer für Fenster- und Türenprofile auch bei der Herstellung von Masten, Trägern oder dergleichen vorgesehen sein; gemäß dem vorliegenden Vorschlag faserverstärkte Platten können beispielsweise im Fahrzeug- oder Behälterbau sowie in der Möbelindustrie verwendet werden.Allow directions of stress. The use of rod-like components, which are fiber-reinforced according to the present proposal, can also be provided for the manufacture of masts, beams or the like in addition to window and door profiles; According to the present proposal, fiber-reinforced panels can be used, for example, in vehicle or container construction and in the furniture industry.

An den beiden Schmalseiten des Kerns 4 stellen die Deckplatten 5, die den Leichtbauplatten 6 unmittelbar anliegen, lediglich die inneren von insgesamt zwei Schichten dar. Die an diesen beiden Schmalseiten des Kerns 4 vorgesehenen Außenplatten 7 und die beiden inneren Deckplatten 5 nehmen jeweils zwischen sich eine Schicht von zugfesten Fasern 8 auf, die in Längsrichtung des Kerns 4 eine hohe Zugfestigkeit aufweisen. Es handelt sich dabei um unidirektionale Glasfasern, die unter Vorspannung gehalten und mit den Deck- bzw. Außenplatten 5 und 7 verbunden worden sind.

These are unidirectional glass fibers which have been held under tension and connected to the cover and outer plates 5 and 7. Due to the pretensioning of the fibers 8, the core 4 has a very high bending stiffness.
