Description

Die Erfindung betrifft ein Stütz- und Verbindungsprofil aus Leichtmetall für ein selbsttragendes Gerüst, insbesondere für Leichtbauhallen und Großzeltkonstruktionen, dass wenigstens eine in Längsrichtung des Profilkörpers verlaufende Verstärkungseinlage aus einem Faserverbundwerkstoff aufweist. Weiter betrifft die Erfindung ein Verfahren zur Herstellung eines faserverstärkten Metallprofils.The invention relates to a support and connection profile made of light metal for a self-supporting framework, in particular for lightweight halls and large tent structures that has at least one running in the longitudinal direction of the profile body reinforcing insert of a fiber composite material. Furthermore, the invention relates to a method for producing a fiber-reinforced metal profile.

Die Erfindung betrifft ein Stütz- und Verbindungsprofil aus Leichtmetall für ein selbsttragendes Gerüst, insbesondere für Leichtbauhallen und Großzeltkonstruktionen, das wenigstens eine in Längsrichtung des Profilkörpers verlaufende Verstärkungseinlage aus einem Faserverbundwerkstoff aufweist.The invention relates to a support and connection profile made of light metal for a self-supporting framework, in particular for lightweight buildings and large tent structures, which has at least one running in the longitudinal direction of the profile body reinforcing insert of a fiber composite material.

Derartige Profile sind aus der WO 01/46536 bekannt. Diese bekannten Stütz- und Verbindungsprofile weisen die Verstärkungslagen in Vertiefungen der Außenfläche des Profilkörpers auf, wobei die Verstärkungslagen nach innen oder außen bereichsweise freiliegen und nicht vollständig umschlossen sind. In Abhängigkeit der Verbindungsart zwischen dem Profilkörper und der Verstärkungseinlage lassen sich unterschiedlich große Kräfte von dem Profilkörper auf die Verstärkungslagen übertragen.Such profiles are from the WO 01/46536 known. These known support and connection profiles have the reinforcing layers in recesses of the outer surface of the profile body, wherein the reinforcing layers are exposed to the inside or outside in areas and are not completely enclosed. Depending on the type of connection between the profile body and the reinforcing insert, forces of different magnitude can be transmitted from the profile body to the reinforcing layers.

Ein besonderes Problem besteht bei der Herstellung von Stütz- und Verbindungsprofilen, die für Leichtbauhallen und Großzeltkonstruktionen eingesetzt werden sollen. Bei diesen Bauwerken können die Stütz- und Verbindungsprofile eine große Länge von teilweise über 10 Meter erreichen. Hier hat es sich in der Vergangenheit als besonders schwierig erwiesen, eine gute dauerhafte Verbindung zwischen einer Faserverstärkung und dem meist aus Aluminium bestehenden Metallprofil herzustellen. Von besonderer Bedeutung ist dabei, dass derartige Bauwerke auch unterschiedlichen klimatischen Bedingungen ausgesetzt werden. So müssen faserverstärkte Stütz- und Verbindungsprofile auch zumindest in einem Temperaturbereich von -20°C bis 80°C eine sichere Verbindung zwischen der Faserverstärkung und dem Metallprofil beibehalten können. Aus der DE 10 2005 005 729 A1 , der GB 2 082 235 A und der WO 2006/138025 A1 sind Profile mit einer Verstärkungseinlage bekannt, bei denen die Verbindung des Profils mit der Verstärkungseinlage mittels eines Laminierharzes erfolgt. Weitere Profile mit Verstärkungseinlage sind aus der US 2006/0070340 A1 und der FR 2 084 520 bekannt. Das aus DE 10 2005 005 729 A1 bekannte Profil entspricht dem Oberbegriff des Anspruchs 1.A particular problem exists in the production of support and connection profiles which are to be used for lightweight construction halls and large tent constructions. In these structures, the support and connection profiles can reach a great length, sometimes over 10 meters. Here, it has proven particularly difficult in the past to have a good permanent bond between a fiber reinforcement and the most aluminum To produce metal profile. Of particular importance is that such structures are exposed to different climatic conditions. Thus, fiber-reinforced support and connection profiles must also be able to maintain a secure connection between the fiber reinforcement and the metal profile, at least in a temperature range from -20 ° C to 80 ° C. From the DE 10 2005 005 729 A1 , the GB 2 082 235 A and the WO 2006/138025 A1 Profiles are known with a reinforcing insert, in which the connection of the profile with the reinforcing insert by means of a laminating resin. Other profiles with reinforcing insert are from the US 2006/0070340 A1 and the FR 2 084 520 known. The end DE 10 2005 005 729 A1 known profile corresponds to the preamble of claim 1.

Es ist daher eine Aufgabe der vorliegenden Erfindung, die Verbindung zwischen Verstärkungslage und Profilkörper zu verbessern, wobei die Verstärkungslage gleichzeitig besonders wirkungsvoll vor Beschädigungen geschützt werden soll.It is therefore an object of the present invention to improve the connection between reinforcing layer and profile body, wherein the reinforcing layer is to be protected against damage at the same time particularly effective.

Diese Aufgabe wird durch ein Profil nach Anspruch 1 sowie ein Verfahren nach Anspruch 10 gelöst. Bei der vorliegenden Erfindung ist in einem zu der Längsrichtung des Profilkörpers senkrechten Querschnitt in dem Profilkörper wenigstens eine geschlossene Kammer ausgebildet, in der wenigstens eine Verstärkungseinlage stoff-, form- und/oder kraft-schlüssig fixiert ist. Eine das Verbindungsprofil umgebende geschlossene Kammer bietet den Vorteil, dass die Kräfte über die gesamte Verstärkungseinlage eingeleitet bzw. aufgefangen werden können. Zudem ist die Verstärkungseinlage in der geschlossenen Kammer im Profilkörper vor mechanischen oder sonstigen Beschädigungen wirkungsvoll geschützt. Die dadurch erreichte optimale Ausnutzung der physikalischen Eigenschaften der Verstärkungseinlage unter Berücksichtigung der auftretenden Belastungen ermöglicht darüber hinaus eine Reduzierung der Dimensionierung von dem Profilkörpermaterial. Der Grund dafür liegt darin, dass die Kräfte, insbesondere die Biegemomente und Zug- und Druckkräfte, wie sie bspw. bei Windbelastungen auftreten, primär von der Verstärkungseinlage aufgefangen werden und nicht vom Profilkörper getragen werden müssen.This object is achieved by a profile according to claim 1 and a method according to claim 10. In the present invention, at least one closed chamber is formed in a profile perpendicular to the longitudinal direction of the profile body in the profile body, in which at least one reinforcing insert is fixed in terms of material, shape and / or force. A closed chamber surrounding the connection profile offers the advantage that the forces can be introduced or absorbed over the entire reinforcement insert. In addition, the reinforcing insert is effectively protected in the closed chamber in the profile body from mechanical or other damage. The optimal utilization of the physical properties of the reinforcing insert, taking into account the loads occurring, also enables a reduction of the dimensioning of the profiled body material. The reason for this is that the forces, in particular the bending moments and tensile and compressive forces, like them For example, occur at wind loads, are primarily collected by the reinforcing insert and must not be borne by the profile body.

Wird die Verstärkungseinlage in eine Kammer eingegossen, wird auf diese Weise eine sehr feste und hohe Kräfte übertragende Verbindung zwischen der Verstärkungseinlage und dem Profilkörper geschaffen, was ein hohes Maß an Stabilität und Festigkeit für die gesamte Gerüstkonstruktion bewirkt. Für eine sichere Verbindung zwischen Profilkörper und Verstärkungseinlage sorgt auch gleichzeitiges oder separates Einkleben der Verstärkungseinlage in den Profilkörper. Alternativ oder zusätzlich ist es möglich, eine Niet- oder Schraubverbindung für die Fixierung der Verstärkungseinlage in dem Profilkörper zu verwenden.If the reinforcing insert is poured into a chamber, a very strong and high forces transmitting connection between the reinforcing insert and the profile body is created in this way, which is a high degree of Stability and strength for the entire framework construction causes. For a secure connection between profile body and reinforcing insert also ensures simultaneous or separate sticking of the reinforcing insert in the profile body. Alternatively or additionally, it is possible to use a rivet or screw connection for fixing the reinforcing insert in the profile body.

Grundsätzlich ist es möglich, die geschlossene Kammer aus zwei oder mehr Elementen zu bilden. Hierzu kann nach einer Ausführungsform, die insbesondere mit Hinblick auf die Montage Vorteile bietet, eine geschlossene Kammer durch einen Wandabschnitt des Profilkörpers sowie durch eine Abdeckung oder dgl. ausgebildet sein. Dabei kann die Abdeckung lösbar mit dem Profilkörper mittels z.B. Klemm-, Rast- Schnapp-, oder Steckverbindungen verbunden sein. Es wird jedoch bevorzugt, wenn die wenigstens eine geschlossene Kammer einstückig mit dem Profilkörper ausgebildet ist.In principle, it is possible to form the closed chamber from two or more elements. For this purpose, according to an embodiment which offers advantages in particular with regard to the assembly, a closed chamber can be formed by a wall section of the profile body as well as by a cover or the like. The cover can be detachably connected to the profile body by means of e.g. Clamping, latching snap, or plug connections be connected. However, it is preferred if the at least one closed chamber is formed integrally with the profile body.

Nach einer besonders bevorzugten Ausführungsform der Erfindung ist die wenigstens eine geschlossene Kammer derart gestaltet, dass ihr Lumen in einem zur Längsrichtung des Profikörpers senkrechten Querschnitt größer als die Verstärkungseinlage ist. Mit anderen Worten verbleibt zwischen der Innenfläche der Kammer und der Außenfläche der beispielsweise lamellenartig gestalteten Faserverstärkung ein Spalt, welcher zur Verklebung der Faserverstärkung mit dem Profil genutzt werden kann. Eine - mit Ausnahme der Stirnseiten - allseitige flächige Verklebung ist für eine gute Verbindung der Faserverstärkung mit dem Metallprofil sehr hilfreich. Die Faserverstärkung kann nur dann wirkungsvoll zur Aufnahme von Zug- oder Druckkräften herangezogen werden, wenn eine derartige gute Verklebung mit dem Metallprofil vorhanden ist.According to a particularly preferred embodiment of the invention, the at least one closed chamber is designed such that its lumen in a direction perpendicular to the longitudinal direction of the professional body cross section is greater than the reinforcing insert. In other words, a gap which can be used for bonding the fiber reinforcement to the profile remains between the inner surface of the chamber and the outer surface of the lamellar fiber reinforcement, for example. An all-round surface bonding, with the exception of the front sides, is very helpful for a good connection of the fiber reinforcement to the metal profile. The fiber reinforcement can only be effectively used to absorb tensile or compressive forces if such a good bond with the metal profile is present.

In Weiterbildung dieses Erfindungsgedanken ist es vorgesehen, dass auf der Außenseite der Verstärkungseinlage wenigstens ein Führungs- und/oder Abstandselement vorgesehen ist. Ein solches Abstands- und/oder Führungselement kann vorzugsweise als eine sich in Längsrichtung des Profilkörpers erstreckende Rippe ausgebildet sein. Es können jedoch auch mehrere punkt- oder stegförmige Vorsprünge, die regelmäßig oder unregelmäßig über die Außenfläche der Verstärkungseinlage verteilt sind, hierzu eingesetzt werden. Wesentlich ist, dass die Führungs- und/oder Abstandselemente einen definierten Mindestabstand zwischen der Außenseite der Verstärkungseinlage und der Innenseite der geschlossenen Kammer bewirken. Hierdurch ist es möglich, eine flächige Verklebung der Verstärkungseinlage mit dem Metallprofil auch über die gesamte Länge des Profils zu erreichen. Dabei ist es unschädlich, wenn sich die Innenseite der Kammer bzw. die Außenseite der Verstärkungseinlage im Bereich der Führungs- und/oder Abstandselemente tatsächlich berühren oder zumindest sehr nahe kommen, solange im Übrigen eine flächige Verklebung ermöglicht wird. Die Verwendung von Führungs- und/oder Abstandselementen ist insbesondere dann wichtig, wenn die erfindungsgemäßen Stütz- und Verbindungsprofile vergleichsweise lang sind, das heißt beispielsweise mehrere Meter lange sind, da die Faserverstärkung anderenfalls mit ihrer Unterseite aufgrund der Schwerkraft auf einer Fläche der Kammer aufliegen würde, so dass dort keine Verklebung stattfinden könnte.In development of this invention, it is envisaged that on the Outside of the reinforcing insert at least one guide and / or spacer element is provided. Such a spacing and / or guide element can preferably be designed as a rib extending in the longitudinal direction of the profile body. However, it is also possible to use a plurality of punctiform or web-shaped projections which are regularly or irregularly distributed over the outer surface of the reinforcing insert. It is essential that the guide and / or spacer elements cause a defined minimum distance between the outside of the reinforcing insert and the inside of the closed chamber. This makes it possible to achieve a surface bonding of the reinforcing insert with the metal profile over the entire length of the profile. It is harmless, if the inside of the chamber or the outside of the reinforcing insert in the area of the guide and / or spacer elements actually touch or at least come very close, as long as otherwise a surface bonding is possible. The use of guide and / or spacer elements is particularly important when the support and connection profiles according to the invention are comparatively long, that is, for example, several meters long, otherwise the fiber reinforcement would rest with its bottom due to gravity on a surface of the chamber so that no gluing could take place there.

Zum Erreichen einer hohen Feuerfestigkeit der Profile können dem Profilkörper schwer entflammbare Chemikalien beigemischt sein. Auf diese Weise können u.a. die bei Bau und Betrieb von Zelten geltenden Richtlinien eingehalten werden. So ist in Richtlinien für Zelt- oder Hallenkonstruktionen vorgeschrieben, dass alle Baustoffe entsprechend DIN 4102 Teil 1 mindestens schwer entflammbar sein müssen. Nur für Bedachungen, die höher als 2,30 m über begehbaren Flächen liegen, dürfen normal entflammbare Baustoffe nach DIN 4102 Teil 1 verwendet werden. In anderen Ländern werden Zelte oder Hallen teilweise wie sonstige bauliche Anlagen behandelt, d.h. sie unterliegen auch den Brandschutzbestimmungen für solche bauliche Anlagen. Diese sehen teilweise vor, dass die Bauten 30 oder 60 min dem Feuer widerstehen müssen. Aluminium und Stahl können dies alleine nicht leisten, sondern verformen sich bzw. beginnen zu schmelzen. Durch die Zugabe von entsprechenden Chemikalien, wie Aluminiumtrihydrat, Brom oder dgl. können Feuerklassen erreicht werden, jede nationale Brandschutzvorschrift erfüllen.To achieve a high fire resistance of the profiles flame-retardant chemicals can be added to the profile body. In this way, among other things, the applicable guidelines for the construction and operation of tents can be met. For example, guidelines for tent or hall constructions stipulate that all building materials in accordance with DIN 4102 Part 1 must be at least flame retardant. Only for roofs that are higher than 2.30 m above accessible areas, may normal inflammable building materials in accordance with DIN 4102 Part 1 be used. In other countries, tents or halls are treated in part as other structures, ie they are also subject to the Fire protection regulations for such structures. These provide in part that the buildings have to resist fire for 30 or 60 minutes. Aluminum and steel can not do this alone, but deform or start to melt. By adding appropriate chemicals such as aluminum trihydrate, bromine or the like, fire classes can be achieved to meet any national fire safety regulations.

Zur Verwendung in Leichtbauhallen und Großzeltkonstruktionen können die erfindungsgemäßen Stütz- und Verbindungsprofile eine im Vergleich zu ihren übrigen Abmessungen große Länge aufweisen. So kann die Länge der Metallprofile beispielsweise um den Faktor 20, insbesondere jedoch um den Faktor 50 bis etwa um dem Faktor 150, größer als dessen Breite und/oder Höhe sein. Dabei kann die Gesamtlänge der faserverstärkten Metallprofile je nach Einsatzzweck über 10 Meter betragen.For use in lightweight buildings and large tent constructions support and connection profiles according to the invention may have a great length compared to their other dimensions. Thus, the length of the metal profiles, for example, by a factor of 20, but in particular by a factor of 50 to about a factor of 150, be greater than its width and / or height. The total length of the fiber-reinforced metal profiles can be over 10 meters, depending on the purpose.

Zur Anbindung weiterer Bauteile, insbesondere zur Anbindung von Zeltbahnen, Wandelementen, Fenstern oder dergleichen, sind vorzugsweise Nuten in dem erfindungsgemäßen Stütz- und Verbindungsprofil vorgesehen. Dabei wird es besonders bevorzugt, wenn der Profilkörper in einem zu der Längsrichtung des Profilkörpers senkrechten Querschnitt annähernd rechteckig ist, wobei dessen Höhe größer als dessen Breite ist, und wobei in wenigstens zwei Ecken jeweils wenigstens eine Nut zur Aufnahme eines Keders oder dergleichen vorgesehen sind. Besonders bevorzugt wird bei einem rechteckigem Querschnitt des Profilkörpers die Anordnung von jeweils einer Nut in jeder der vier Ecken. Grundsätzlich ist es jedoch auch möglich, derartige Nuten oder andere geeignete Befestigungseinrichtungen an anderen Positionen des Profilkörpers vorzusehen.For connection of further components, in particular for the connection of tarpaulins, wall elements, windows or the like, grooves are preferably provided in the support and connection profile according to the invention. It is particularly preferred if the profile body is approximately rectangular in a perpendicular to the longitudinal direction of the profile body cross-section, the height of which is greater than its width, and wherein in at least two corners each have at least one groove for receiving a welt or the like. With a rectangular cross-section of the profile body, the arrangement of one groove in each of the four corners is particularly preferred. In principle, however, it is also possible to provide such grooves or other suitable fastening devices at other positions of the profile body.

Erfindungsgemäß kann der Profilkörper als Pfosten, Dachriegel, Giebelstütze, Giebelquertraverse, Pfette, Tuchhalter, Pfostenschuh, Giebelstütze mit Bodenbefestigung, Stiel-Riegel-Verbindung im Traufbereich, Firstverbindung zwischen einzelnen Dachriegeln, Verbindung zwischen Giebelstützen und Dachriegeln, Kreuzverband zur Aussteifung zwischen Pfosten und zwischen Dachriegeln oder dgl. Gerüstteil ausgebildet sein. Auf diese Weise kann das selbsttragende Gerüst vollständig aus Profilen der erfindungsgemäßen Art aufgebaut werden.According to the invention, the profile body as a post, roof bolt, gable support, gable cross-beam, purlin, cloth holder, post shoe, gable support with ground attachment, stem-bolt connection in eaves, ridge connection between individual roof bars, connection between gable supports and roof bars, cross dressing for stiffening between posts and between roof bars or the like. Scaffolding part may be formed. In this way, the self-supporting framework can be constructed entirely of profiles of the type according to the invention.

Die der Erfindung zugrundeliegende Aufgabe wird weiter durch ein Verfahren zur Herstellung des oben erwähnten faserverstärkten Leichtmetallprofils mit folgenden Verfahrensschritten gelöst: Zunächst wird ein Profilkörper bereitgestellt, in welchem in einem zu der Längsrichtung des Profilkörpers senkrechten Querschnitt wenigstens eine geschlossene Kammer ausgebildet ist. Danach wird ein Klebstoff in diese wenigstens eine geschlossene Kammer eingefüllt. Schließlich wird eine Glasfasern und/oder Kohlenstofffasern enthaltende Verstärkungseinlage zusammen mit Klebstoff in die zuvor bereits zumindest teilweise mit Klebstoff befüllte geschlossene Kammer eingeführt. Dieses erfindungsgemäße Verfahren bewirkt, dass eine - mit Ausnahme der Stirnseite - allseitige gute Verklebung zwischen der geschlossenen Kammer und der Verstärkungseinlage erreicht wird. Durch das Vorbefüllen der geschlossenen Kammer mit dem Klebstoff wird vermieden, dass bei der gemeinsamen Einführung von Verstärkungseinlage und Klebstoff der Klebfilm zwischen der Verstärkungseinlage und der Kammer abreißt. Vielmehr umfließt der Klebstoff die Verstärkungseinlage während des Einführens in die Kammer. Insbesondere bei sehr langen Metallprofilen hat es sich als besonders zweckmäßig erwiesen, wenn sowohl das Metallprofil als auch die Verstärkungseinlage während der Montage im Wesentlichen horizontal ausgerichtet sind. Dies vereinfacht die Handhabung und verringert auch die Gefahr von Lufteinschlüssen, die bei einer senkrechten Ausrichtung des Metallprofils auftreten könnten.The object underlying the invention is further achieved by a method for producing the above-mentioned fiber-reinforced light metal profile with the following method steps: First, a profile body is provided in which at least one closed chamber is formed in a cross section perpendicular to the longitudinal direction of the profile body. Thereafter, an adhesive is filled in this at least one closed chamber. Finally, a reinforcing insert containing glass fibers and / or carbon fibers is introduced together with adhesive into the closed chamber which has already been filled at least partially with adhesive. This method according to the invention has the effect that - with the exception of the front side - all-round good bonding between the closed chamber and the reinforcing insert is achieved. Pre-filling the closed chamber with the adhesive prevents the adhesive film between the reinforcing insert and the chamber from tearing off when the reinforcing insert and adhesive are introduced together. Rather, the adhesive flows around the reinforcing insert during insertion into the chamber. In particular, for very long metal profiles, it has proved to be particularly useful if both the metal profile and the reinforcing insert during assembly are aligned substantially horizontally. This simplifies handling and also reduces the risk of trapped air, which could occur with a vertical orientation of the metal profile.

Es hat sich als besonders vorteilhaft erwiesen, wenn die Viskosität des Klebstoffes zwischen etwa 1.000 mPas und etwa 3.500 mPas liegt. Ein besonders bevorzugter Bereich liegt bei etwa 2.100 mPas bis etwa 2.500 mPas (jeweils gemessen bei 25°C). Als besonders vorteilhaft haben sich weiter Klebstoffe, insbesondere Zweikomponenten-Klebstoffe, mit einer Reisfestigkeit von etwa 20 MPa bis etwa 30 MPa und/oder einer Reißdehnung zwischen 200 % und 400 %, insbesondere etwa 300 % (jeweils gemessen nach ISO 527) erwiesen.It has proven to be particularly advantageous if the viscosity of the adhesive is between about 1,000 mPas and about 3,500 mPas. A particularly preferred range is about 2,100 mPas to about 2,500 mPas (measured in each case at 25 ° C). Adhesives, in particular two-component adhesives, having a rice strength of about 20 MPa to about 30 MPa and / or an elongation at break of between 200% and 400%, in particular about 300% (each measured to ISO 527), have proven to be particularly advantageous.

Um eine besonders gute Verbindung zwischen dem Metallprofil und der Verstärkungseinlage zu erreichen, wird es bevorzugt, wenn während des Einführens der Verstärkungseinlage zusammen mit dem Klebstoff in die geschlossene Kammer zwischen der Außenseite der Verstärkungseinlage und er Innenseite der Kammer allseits (mit Ausnahme der Stirnseiten) ein Klebfilm mit der Schichtdicke von wenigstens 0,3 mm, insbesondere zwischen etwa 0,4 mm und etwa 2,5 mm, entsteht. Dies kann insbesondere durch die Verwendung der oben beschriebenen Führungs- und/oder Abstandselemente erleichtert werden.In order to achieve a particularly good connection between the metal profile and the reinforcing insert, it is preferred if during insertion of the reinforcing insert together with the adhesive in the closed chamber between the outside of the reinforcing insert and he inside of the chamber on all sides (except the end faces) Bonding film with the layer thickness of at least 0.3 mm, in particular between about 0.4 mm and about 2.5 mm, is formed. This can be facilitated in particular by the use of the above-described guide and / or spacer elements.

Es wird bevorzugt, wenn der erfindungsgemäße Profilkörper einen annähernd rechteckigen Querschnitt aufweist, wobei dessen Höhe größer als dessen Breite ist. Vorzugsweise sind in der Nähe der Oberseite und in der Nähe der Unterseite des Profilkörpers jeweils eine geschlossene Kammer vorgesehen, wobei in jede dieser Kammern nach dem erfindungsgemäßen Verfahren Klebstoff und eine Verstärkungseinlage eingebracht wird.It is preferred if the profile body according to the invention has an approximately rectangular cross-section, wherein its height is greater than its width. Preferably, in each case a closed chamber is provided in the vicinity of the upper side and in the vicinity of the underside of the profile body, adhesive and a reinforcing insert being introduced into each of these chambers by the method according to the invention.

Fig. 1 zeigt ein nicht erfindungsgemäßes Stütz- und Verbindungsprofil 1, mit einem im Querschnitt dargestellten Stütz- und Verbindungsprofilkörper 2. Das Profil besitzt eine im Wesentlichen rechteckige Form und weist an den jeweiligen Ecken nach außen offene Nuten 3 auf, in denen nicht dargestellte Befestigungs- und/oder Funktionselemente, beispielsweise über Keder befestigbare Wände, angebracht werden können. An den einander gegenüberliegenden kurzen Seiten des Querschnitts ist im Inneren des Profilkörpers 2 zwischen zwei Nuten 3 jeweils eine Kammer 4 ausgebildet, die sich in einem zu der Längsrichtung des Profilkörpers senkrechtem Querschnitt erstreckt und die eine Verstärkungseinlage 5 aufweist. Die Kammern 4 weisen in der dargestellten Ausführungsform einen zumindest im Wesentlichen rechteckigen Querschnitt auf, wobei die Breite der Kammern 4, d.h. die Erstreckung zwischen den Nuten 3, größer als die Dicke der Kammern ist. Diese Ausgestaltung ermöglicht eine besonders hohe Biegefestigkeit des Profils 1. Fig. 1 shows a non-inventive support and connection profile 1, with a cross-sectional support and connection profile body 2. The profile has a substantially rectangular shape and has at the respective corners outwardly open grooves 3, in which not shown mounting and / or functional elements, for example via keder fastenable walls, can be attached. On the opposite short sides of the cross section, a chamber 4 is formed in the interior of the profile body 2 between two grooves 3, which extends in a direction perpendicular to the longitudinal direction of the profile body cross section and having a reinforcing insert 5. The chambers 4 have in the illustrated embodiment an at least substantially rectangular cross-section, wherein the width of the chambers 4, ie the extension between the grooves 3, is greater than the thickness of the chambers. This embodiment allows a particularly high bending strength of the profile. 1

Die Verstärkungseinlage 5 ist durch vorzugsweise unidirektional verlaufende Fasern, insbesondere aus Kohlenstoff und/oder Glas, und eine diese umgebende Matrix 6 gebildet. Die Verstärkungseinlage ist in der Kammer 4 fixiert, indem die Fasern mit der Matrix in der Kammer vergossen bzw. verklebt sind.The reinforcing insert 5 is preferably by unidirectional fibers, in particular carbon and / or glass, and a surrounding these Matrix 6 formed. The reinforcing insert is fixed in the chamber 4 by the fibers are potted or glued to the matrix in the chamber.

Eine weitere Variante zur Fixierung der Verstärkungseinlage 5 in der Kammer 4 ist in Fig. 2 dargestellt. Dargestellt ist auch hier das Stütz- und Verbindungsprofil 1, bestehend aus dem im Querschnitt dargestellten Stütz- und Verbindungsprofilkörper 2 und den Nuten 3 an den Ecken des Profilkörpers 2. Im Gegensatz zu der Ausführungsform nach Fig. 1 weist der in Fig. 2 dargestellte Profilkörper 2 einen im Wesentlichen in der Mitte des Profilquerschnitts gelegenen Steg 7 auf, der die beiden langen Seiten des Profilkörpers 2 miteinander verbindet. In dem Steg 7 ist die Kammer 4 ausgebildet, die die Verstärkungseinlage 5 aufnimmt. Die Verstärkungseinlage 5 ist mit dem Steg 7 über eine Nietverbindung 8 fixiert.Another variant for fixing the reinforcing insert 5 in the chamber 4 is in Fig. 2 shown. Also shown here is the support and connection profile 1, consisting of the support and connection profile body 2 shown in cross section and the grooves 3 at the corners of the profile body 2. In contrast to the embodiment according to Fig. 1 has the in Fig. 2 Profiled body 2 shown a substantially located in the middle of the profile cross section web 7, which connects the two long sides of the profile body 2 together. In the web 7, the chamber 4 is formed, which receives the reinforcing insert 5. The reinforcing insert 5 is fixed to the web 7 via a rivet connection 8.

Statt einer Nietverbindung sind auch andere Verbindungen, wie z.B. Schraubverbindungen, möglich. Auch der Steg kann je nach Einsatzfall variiert werden. So ist es auch möglich, dass der Steg die beiden kurzen Seiten des Profilkörpers oder diagonal die Ecken miteinander verbindet. Ebenso kann der Profilkörper 2 eine Vielzahl von Stegen aufweisen und die Stege wiederum eine Vielzahl von Kammern. Darüber hinaus muss die Kammer 4 nicht wie in den Figuren 1 und 2 gezeigt einstückig mit dem Profilköper 2 ausgebildet sein, sondern kann aus einer Anzahl von Elementen gebildet werden, wie z.B. bei einer Kammer, die zumindest bereichsweise durch einen Wandabschnitt des Profilkörpers sowie durch eine separate Abdeckung gebildet wird.Instead of a riveted joint, other connections, such as screw, are possible. Also, the bridge can be varied depending on the application. So it is also possible that the bridge connects the two short sides of the profile body or diagonally the corners together. Likewise, the profile body 2 may have a plurality of webs and the webs in turn a plurality of chambers. In addition, the chamber 4 does not have as in the FIGS. 1 and 2 may be formed integrally with the profile body 2, but may be formed from a number of elements, such as in a chamber which is at least partially formed by a wall portion of the profile body and by a separate cover.

Eine derartige nicht erfindungsgemäße Ausbildungsform eines Profils ist in Fig. 3 gezeigt, das einen ähnlichen Aufbau wie das in Fig. 1 gezeigte Stütz- und Verbindungsprofil 1 aufweist. Die Kammern 4 werden jeweils zum einen durch einen Wandabschnitt 9, der in dieser Ausbildungsform in den Profilkörper 2 eingelassen ist, als auch durch eine Abdeckung 10 ausgebildet. In dieser Kammer 4 befindet sich die Verstärkungseinlage 5, die mittels z.B. Eingießen, Kleben, Schrauben, Nieten oder durch die Abdeckung 10 selber fixiert wird. Die Abdeckung 10 ist mit dem Profilkörper 2 mittels lösbarer Verbindungen 11 wie z.B. Klemm, Rast, Schnapp,- oder Steckverbindungen verbunden. Weitere Varianten umfassen Kammern mit Abdeckungen an den Innenseiten des Profilkörpers. Dabei ist es grundsätzlich auch möglich, die Abdeckung nicht in einem ausgesparten Wandabschnitt 9 auf der Oberfläche des Profilkörpers 2 anzuordnen, sondern direkt auf der Oberfläche des Profilkörpers 2. Die Abdeckung 10 bzw. ein den Wandabschnitt 9 verschließender Deckel können auch über eine Verklebung mit dem Profilkörper 2 und/oder der Verstärkungseinlage 5 verbunden werden.Such a non-inventive embodiment of a profile is in Fig. 3 shown, which has a similar structure to that in Fig. 1 Having shown support and connection profile 1. The chambers 4 are each formed on the one hand by a wall portion 9, which is embedded in the profile body 2 in this embodiment, as well as by a cover 10. In this chamber 4 is the reinforcing insert 5, by means of eg pouring, gluing, screws, rivets or is fixed by the cover 10 itself. The cover 10 is connected to the profile body 2 by means of releasable connections 11 such as clamping, latching, snap, - or plug connections. Other variants include chambers with covers on the inner sides of the profile body. It is also possible in principle not to arrange the cover in a recessed wall portion 9 on the surface of the profile body 2, but directly on the surface of the profile body 2. The cover 10 and the wall portion 9 occlusive cover can also be a bond with the Profile body 2 and / or the reinforcing insert 5 are connected.

In den Fig. 4 und 5 sind jeweils Ausführungsformen eines erfindungsgemäßen Stütz- und Verbindungsprofil 1 dargstellt, wobei jeweils ähnlich der Ausführungsform nach Fig. 1 sowohl in der Nähe der Oberseite als auch in der Nähe der Unterseite des Profilkörpers 2 jeweils eine geschlossene Kammer 4 vorgesehen ist, in welche eine Faserverstärkung 5 eingebracht und verklebt ist. Die Profilkörper nach den Fig. 4 und 5 sind so gestaltet, dass der Profilkörper nach Fig. 5 in den Profilkörper nach Fig. 4 eingesetzt werden kann. Damit eignet sich der Profilkörper nach Fig. 5 als ein Verbindungselement zwischen zwei aneinander angrenzenden Profilkörpern nach Fig. 4.In the Fig. 4 and 5 are each embodiments of a support and connection profile 1 according to the invention dargstellt, each similar to the embodiment of Fig. 1 both in the vicinity of the top and in the vicinity of the underside of the profile body 2 is provided in each case a closed chamber 4, in which a fiber reinforcement 5 is introduced and bonded. The profile body after the Fig. 4 and 5 are designed so that the profile body after Fig. 5 in the profile body after Fig. 4 can be used. Thus, the profile body is suitable for Fig. 5 as a connecting element between two adjoining profile bodies Fig. 4 ,

In der Detailansicht X der Fig. 6 ist zu erkennen, dass bei der Ausführungsform nach den Figuren 4 und 5 in den Ecken der Verstärkungseinlage 5 jeweils ein Vorsprung 12 vorgesehen ist, der etwa in die entsprechenden Ecken der Kammern 4 weist. Dieser Vorsprung 12 bildet ein in Längsrichtung des Profilkörpers 2 verlaufendes Führungs- und/oder Abstandselement, welches sicher stellen soll, dass die Verstärkungseinlage 5 nicht flächig an einer der Wände der geschlossenen Kammer 4 anliegt, sondern dass die Verstärkungseinlage 5 - ggf. mit Ausnahme der Führungs- und/oder Abstandselemente 12 - flächig mit der Innenseite der Kammer 4 verklebt werden kann. Auf diese Weise wird die Verstärkungseinlage 5 allseits von einem Klebefilm 6 mit einer Schichtdicke von etwa 0,5 mm umschlossen. Hierdurch ist es möglich, dass der Profilkörper 2 bei einer Biegebelastung Zug- und Druckkräfte in die Faserverstärkung abgibt.In the detail view X of the Fig. 6 It can be seen that in the embodiment according to the FIGS. 4 and 5 in each case a projection 12 is provided in the corners of the reinforcing insert 5, which has approximately in the corresponding corners of the chambers 4. This projection 12 forms a running in the longitudinal direction of the profile body 2 guide and / or spacer element, which is to ensure that the reinforcing insert 5 is not flat against one of the walls of the closed chamber 4, but that the reinforcing insert 5 - possibly with the exception Guide and / or spacer elements 12 - can be glued flat with the inside of the chamber 4. In this way, the reinforcing insert 5 is on all sides of an adhesive film 6 with a layer thickness of enclosed about 0.5 mm. This makes it possible that the profile body 2 emits tensile and compressive forces in the fiber reinforcement at a bending load.
