Das Metallprofil soll insbesondere zur Herstellung eines Verbundprofils geeignet sein, das im Baubereich als Fenster-, Tür- oder Fassadenprofil einsetzbar ist. Ferner betrifft die Erfindung ein Verbundprofil mit einem solchen Metallprofil sowie ein Verfahren zur Herstellung des Metallprofils.The invention relates to a metal profile with the features of the preamble of claim 1.

Furthermore, the invention relates to a composite profile with such a metal profile and a method for producing the metal profile.

Stand der TechnikState of the art

Die Verwendung von Metallprofilen zur Herstellung von Fenstern, Türen oder Fassadenkonstruktion ist allgemein bekannt. Metallprofile, insbesondere Stahlprofile, besitzen den Vorteil, dass sie eine hohe Formsteifigkeit besitzen und demzufolge hohe Traglasten aufnehmen können. Als nachteilig erweist sich jedoch die vergleichsweise hohe Wärmeleitfähigkeit des Werkstoffs Metall. Daher gilt es Maßnahmen zu treffen, die den erforderlichen Wärmeschutz gewährleisten.The use of metal profiles for the manufacture of windows, doors or facade construction is well known. Metal profiles, in particular steel profiles, have the advantage that they have high dimensional stability and can therefore absorb high loads. However, the comparatively high thermal conductivity of the metal material has proven to be disadvantageous. It is therefore necessary to take measures to ensure the necessary thermal protection.

Eine Maßnahme kann darin bestehen, eine thermische Trennung vorzusehen. Die thermische Trennung wird in der Regel über ein Isolierprofil aus Kunststoff bewirkt, das zwischen zwei Metallprofilen angeordnet wird. Denn Kunststoff besitzt gegenüber Metall eine deutlich geringere Wärmeleitfähigkeit.One measure can be to provide thermal separation. The thermal separation is usually achieved using a plastic insulating profile that is placed between two metal profiles. Because plastic has a significantly lower thermal conductivity than metal.

Derart thermisch getrennte Profile werden auch Verbundprofile genannt, da mindestens ein Metallprofil und ein Isolierprofil kraft- und/oder formschlüssig verbunden werden. Die Verbindung muss dergestalt sein, dass ein ausreichend stabiler Verbund gewährleistet ist.Profiles that are thermally separated in this way are also called composite profiles, since at least one metal profile and one insulating profile are connected in a non-positive and/or positive manner. The connection must be such that a sufficiently stable connection is guaranteed.

Aus der Offenlegungsschrift DE 35 03 708 A1 ist ein Verfahren zur Herstellung eines Verbundprofils aus wenigstens zwei Profilteilen aus Metall und einer zwischenliegenden wärmeisolierenden Profilschiene bekannt, bei dem zumindest die wärmeisolierende Profilschiene während oder nach dem Zusammenbau der Profilteile lokal angeschmolzen oder erweicht wird und mindestens ein mit einer Rändelung versehener Bereich eines Profilteils aus Metall in den angeschmolzenen oder erweichten Bereich der wärmeisolierenden Profilschiene eingedrückt wird. Auf diese Weise soll ein Formschluss erreicht werden, der eine hohe Schubfestigkeit und Formgenauigkeit des Verbundprofils gewährleistet. Dabei gilt es sicherzustellen, dass andere Bereiche der Profilschiene nicht erwärmt werden, um unerwünschte plastische Verformungen und/oder Materialspannungen infolge der Wärmeeinwirkung auszuschließen. Denn diese könnten den Formschluss beeinträchtigen.From the disclosure document DE 35 03 708 A1 discloses a method for producing a composite profile from at least two profile parts made of metal and an intermediate heat-insulating profile rail, in which at least the heat-insulating profile rail is locally melted or softened during or after assembly of the profile parts and at least one knurled area of a profile part made of metal is pressed into the melted or softened area of the heat-insulating profile rail. In this way, a form fit is to be achieved which ensures high shear strength and dimensional accuracy of the composite profile. It is important to ensure that other areas of the profile rail are not heated in order to rule out unwanted plastic deformation and/or material stresses as a result of the heat effect. Because these could impair the form fit.

Der DE 76 17 158 U1 ist ein thermisch getrenntes Profil zu entnehmen, das aus zwei parallel angeordnete, ineinandergreifende und durch wärmedämmendes Material voneinander getrennte Profilteile besteht. Die formschlüssige Verbindung wird durch Verklemmen hergestellt.The DE 76 17 158 U1 shows a thermally separated profile that consists of two parallel, interlocking profile parts that are separated from one another by thermal insulation material. The positive connection is made by clamping.

Die DE 198 12 190 C1 offenbart ein Verbundprofil, das mindestens ein mit einem Zwischenelement formschlüssig verbundenes Profilelement umfasst. Das Profilelement weist hierzu mindestens eine in Längsrichtung des Profils verlaufende L- oder U-förmige Nut auf, in die ein korrespondierender Verankerungssteg des Zwischenprofils eingreift. Der freie Rand der Nut ist derart auf den Verankerungssteg durch Rollformen angepresst, dass ein Formschluss erzielt wird.The DE 198 12 190 C1 discloses a composite profile which comprises at least one profile element positively connected to an intermediate element. For this purpose, the profile element has at least one L-shaped or U-shaped groove running in the longitudinal direction of the profile, into which a corresponding anchoring web of the intermediate profile engages. The free edge of the groove is pressed onto the anchoring bar by roll forming in such a way that a positive fit is achieved.

Ein weiteres Verbundprofil ist der EP 2 096 250 A2 zu entnehmen, das aus mindestens zwei metallischen Anschlussprofilen besteht, die über mindestens ein dazwischen liegendes aus Kunststoff bestehendes Verbindungsprofil formschlüssig verbunden sind. Der Formschluss wird hier über elastisch verformbare Bügel am Verbindungsprofil erreicht, die in entsprechende Ausnehmungen der Anschlussprofile einclippbar sind.Another composite profile is the EP 2 096 250 A2 can be seen, which consists of at least two metallic connection profiles, which are positively connected via at least one intervening plastic connecting profile. The form fit is achieved here via elastically deformable brackets on the connection profile, which can be clipped into corresponding recesses in the connection profile.

Aus der Offenlegungsschrift EP 2 476 853 A1 ist ferner ein Verfahren zur Herstellung eines Verbundprofils für Fenster, Festverglasungen, Fassaden, Türen oder Lichtdächer bekannt, bei dem eine kraft- und/oder formschlüssige Verbindung zwischen einem Metallprofil und einem Isolierprofil durch plastisches Verformen hergestellt wird. Eine Profilkontur des Isolierprofils wird hierzu in eine Befestigungsnut des Metallprofils eingesetzt. Durch plastisches Verformen, insbesondere durch Anrollen, mindestens eines eine Seitenbegrenzung der Befestigungsnut ausbildenden Profilabschnitts des Metallprofils wird dann der Kraft- und/oder Formschluss hergestellt. Um sicherzustellen, dass das Verbundprofil eine ausreichende Steifigkeit gegen ein Aufbiegen der Befestigungsnut besitzt, wird zudem vorgeschlagen, dass die die Seitenbegrenzungen der Befestigungsnut bildenden Profilabschnitte über weitere Profilabschnitte verbunden sind, die eine Profilschleife beschreiben, die Profilabschnitte umfasst, die zumindest in einem Bereich aneinander angrenzen und im Bereich ihrer Angrenzung miteinander verbunden sind. Vorzugsweise handelt es sich hierbei um Profilabschnitte der Profilschleife, die direkt an die die Seitenbegrenzungen der Befestigungsnut bildenden Profilabschnitte angrenzen. Die Verbindung erfolgt vorzugsweise mittels einer Schweißnaht.From the disclosure document EP 2 476 853 A1 a method for producing a composite profile for windows, fixed glazing, facades, doors or skylights is also known, in which a non-positive and/or positive connection is produced between a metal profile and an insulating profile by plastic deformation. For this purpose, a profile contour of the insulating profile is inserted into a fastening groove of the metal profile. The non-positive and/or positive connection is then produced by plastic deformation, in particular by rolling, of at least one profile section of the metal profile that forms a lateral boundary of the fastening groove. In order to ensure that the composite profile has sufficient rigidity to prevent the fastening groove from bending open, it is also proposed that the profile sections forming the side boundaries of the fastening groove be connected via further profile sections which describe a profile loop comprising profile sections which adjoin one another at least in one area and are connected to each other in the area of their adjoining. Preferably, these are profile sections of the profile loop which directly adjoin the profile sections forming the side boundaries of the fastening groove. The connection is preferably made by means of a weld seam.

Ferner soll das Metallprofil einfach und kostengünstig herstellbar sein.Proceeding from the above-mentioned state of the art, the present invention is based on the object of specifying a metal profile which, in order to produce a composite profile, is non-positively and/or positively connected to an insulating profile is connectable and ensures a stable bond in this arrangement.

Vorteilhafte Weiterbildungen der Erfindung gehen aus den jeweiligen Unteransprüchen hervor.To solve the problem, the metal profile with the features of claim 1 is specified. A composite profile with such a metal profile and a method for producing the metal profile are also specified. Advantageous developments of the invention emerge from the respective dependent claims.

Offenbarung der ErfindungDisclosure of Invention

Das vorgeschlagene Metallprofil ist aus einem Metallblech durch Umformen, insbesondere durch Rollformen, hergestellt worden. Bei dem Metallblech kann es sich insbesondere um ein Blech aus Stahl, Edelstahl, Kupfer oder einer Kupferlegierung handeln. Zur Verbindung mit einem Isolierprofil besitzt das Metallprofil einen eine Nut ausbildenden Profilquerschnitt. Die Nut wird dabei von Profilabschnitten begrenzt, an welche Profilabschnitte anschließen, die in einem gemeinsamen Kontaktbereich aufeinander liegen. Ferner ist vorgesehen, dass die bereichsweise aufeinander liegenden Profilabschnitte außerhalb ihres Kontaktbereichs einen zur Nut hin offenen Spalt begrenzen.The proposed metal profile has been produced from sheet metal by forming, in particular by roll forming. The sheet metal can in particular be a sheet made of steel, stainless steel, copper or a copper alloy. For connection to an insulating profile, the metal profile has a profile cross section forming a groove. The groove is delimited by profile sections which are adjoined by profile sections which lie on top of one another in a common contact area. Furthermore, it is provided that the profile sections lying one on top of the other in certain areas delimit a gap open towards the groove outside of their contact area.

Der zur Nut hin offene Spalt schafft einen Freiraum, der mehrere Vorteile besitzt. Beispielsweise fördert der Freiraum das Abführen von Medien, insbesondere von Ölen, die regelmäßig vor und/oder während des Umformens zum Schutz der Oberflächen des Werkstücks und/oder der Werkzeuge eingesetzt werden. Das durch Umformen hergestellte Metallprofil neigt demnach weniger zum "Ausbluten" und kann entsprechend schneller weiterverarbeitet werden.The gap open towards the groove creates a free space that has several advantages. For example, the free space promotes the removal of media, in particular oils, which are regularly used before and/or during forming to protect the surfaces of the workpiece and/or the tools. The metal profile produced by forming therefore has less of a tendency to "bleed out" and can be further processed correspondingly more quickly.

Ferner kann der durch den Spalt geschaffene Freiraum zur Aufnahme einer Schweißnaht oder eines Klebstoffs genutzt werden, um die beiden spaltbegrenzenden Profilabschnitte zu verbinden. Durch eine entsprechende Verbindung der beiden Profilabschnitte kann die Formsteifigkeit des Metallprofils erhöht werden. insbesondere wird die Gefahr eines unerwünschten Aufbiegens der Nut gemindert, so dass ein dauerhaft stabiler Verbund zwischen dem Metallprofil und einem Isolierprofil gewährleistet ist.Furthermore, the free space created by the gap can be used to accommodate a weld seam or an adhesive in order to connect the two profile sections delimiting the gap. The dimensional stability of the metal profile can be increased by a corresponding connection of the two profile sections. in particular, the risk of the groove bending up undesirably is reduced, so that a permanently stable connection between the metal profile and an insulating profile is ensured.

Sofern die Verbindung der den Spalt begrenzenden Profilabschnitte durch eine Verschweißung bewirkt werden soll, erleichtert der durch den Spalt geschaffene Freiraum das Setzen der Schweißnaht. Denn die Zugänglichkeit wird durch den Spalt verbessert. Ferner vermag eine im Spalt angeordnete Schweißnaht leichter auszugasen, so der Gefahr der Bildung von Lunkern entgegen gewirkt wird. Dadurch verbessert sich die Qualität der Schweißnaht.If the profile sections delimiting the gap are to be connected by welding, the free space created by the gap facilitates the setting of the weld seam. Because accessibility is improved by the gap. Furthermore, a weld seam arranged in the gap can outgas more easily, thus counteracting the risk of cavities forming. This improves the quality of the weld.

Sofern die Verbindung der den Spalt begrenzenden Profilabschnitte durch eine Verklebung bewirkt werden soll, kann der durch den Spalt geschaffene Freiraum zur Aufnahme des Klebstoffs genutzt werden, wobei die Einbringung des Klebstoffs, insbesondere bei Verwendung eines niedrigviskosen Flüssigklebstoffs, sowohl vor, als auch nach dem kraft- und/oder formschlüssigen Verbinden des Metallprofils mit einem Isolierprofil erfolgen kann. Das nachträgliche Verkleben der den Spalt begrenzenden Profilabschnitte hat ebenfalls mehrere Vorteile.If the connection of the profile sections delimiting the gap is to be effected by gluing, the free space created by the gap can be used to accommodate the adhesive, with the introduction of the adhesive, especially when using a low-viscosity liquid adhesive, both before and after the kraft - Can be done and / or form-fitting connection of the metal profile with an insulating profile. The subsequent gluing of the profile sections delimiting the gap also has several advantages.

Ein erster Vorteil ist darin zu sehen, dass der Spalt- bis zum Einbringen des Klebstoffs - die Nut erweitert. Die Herstellung einer kraft- und/oder formschlüssigen Verbindung des Metallprofils mit einem Isolierprofil kann demnach mit einem geringeren Kraftaufwand bewirkt werden. Denn die den Spalt begrenzenden Profilabschnitte verlängern den Hebelarm, der durch die beidseits der Nut angeordneten, nutbegrenzenden Profilabschnitte gebildet wird, so dass nach dem Hebelgesetz die zur Verformung erforderliche Kraft geringer ist. Auf diese Weise vereinfacht der Spalt die Herstellung einer kraft- und/oder formschlüssigen Verbindung zwischen dem Metallprofil und einem Isolierprofil.A first advantage can be seen in the fact that the gap widens the groove until the adhesive is introduced. The production of a non-positive and/or positive connection of the metal profile with an insulating profile can therefore be effected with less effort. This is because the profile sections delimiting the gap lengthen the lever arm, which is formed by the profile sections delimiting the groove arranged on both sides of the groove, so that according to the law of the lever, the force required for deformation is lower. In this way, the gap simplifies the production of a non-positive and/or positive connection between the metal profile and an insulating profile.

Ein weiterer Vorteil ist darin zu sehen, dass der durch den Spalt geschaffene Freiraum ein "Überdrücken" mindestens eines nutbegrenzenden Profilabschnitts ermöglicht, um eine kraft- und/oder formschlüssige Verbindung zwischen dem Metallprofil und dem Isolierprofil herzustellen. Beim "Überdrücken" wird der mindestens eine nutbegrenzende Profilabschnitt über das zur Herstellung der kraft- und/oder formschlüssigen Verbindung erforderlichen Maß hinaus verformt. Stellt sich anschließend - aufgrund einer zusätzlichen elastischen Verformung - der Profilabschnitt teilweise zurück, ist die teilweise Rückstellung für den zu erzielenden Kraft- und/oder Formschluss unschädlich. Denn der die teilweise Rückstellung
bewirkende elastische Verformungsanteil wird durch das anfängliche "Überdrücken" kompensiert.A further advantage can be seen in the fact that the free space created by the gap allows at least one profile section that delimits the groove to be "pressed over" in order to produce a non-positive and/or positive connection between the metal profile and the insulating profile. When "pressing over" the at least one groove-limiting profile section is deformed beyond the amount required to produce the non-positive and/or positive connection. If the profile section then partially resets - due to an additional elastic deformation - the partial reset is harmless for the frictional and/or positive connection to be achieved. For that the partial default
The elastic deformation component that causes it is compensated for by the initial "overpressing".

Der zur Nut hin offene Spalt setzt demnach die Formsteifigkeit des Metallprofils zunächst herab. Die anfänglich geringere Formsteifigkeit kann sich jedoch - wie vorstehend beschrieben - als Vorteil auswirken. Spätestens nach Herstellung einer kraft- und/oder formschlüssigen Verbindung des Metallprofils mit einem Isolierprofil soll jedoch durch eine möglichst hohe Formsteifigkeit des Metallprofils ein dauerhaft stabiler Verbund zwischen dem Metallprofil und dem Isolierprofil gewährleistet sein.The gap open towards the groove accordingly initially reduces the dimensional stability of the metal profile. However, as described above, the initially lower dimensional stability can be an advantage. At the latest after the production of a non-positive and/or positive connection of the metal profile with an insulating profile, however, a permanently stable connection between the metal profile and the insulating profile should be ensured by the highest possible dimensional stability of the metal profile.

Erfindungsgemäß wird daher vorgeschlagen, dass die den Spalt begrenzenden Profilabschnitte im Bereich des Spalts verschweißt oder verklebt sind. Denn die Verschweißung oder Verklebung der beiden Profilabschnitte führt zu der gewünschten hohen Formsteifigkeit des Metallprofils. Insbesondere wirkt sie einem unerwünschten Aufbiegen der Nut entgegen, nachdem der Kraft- und/oder Formschluss mit einem Isolierprofil hergestellt worden ist.According to the invention, it is therefore proposed that the profile sections delimiting the gap be welded or glued in the area of the gap. Because the welding or gluing of the two profile sections leads to the desired high dimensional stability of the metal profile. In particular, it counteracts an undesired bending of the groove after the non-positive and/or positive connection has been established with an insulating profile.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist im Bereich des Spalts, vorzugsweise im Bereich des zur Nut hin offenen Endes des Spalts, eine Schweißnaht zur Verbindung der den Spalt begrenzenden Profilabschnitte angeordnet. Die Schweißnaht kann insbesondere eine Laserschweißnaht sein, da Laserschweißnähte besonders präzise ausgeführt werden können. Der Spalt erleichtert zudem das Setzen der Schweißnaht. Dies gilt insbesondere, wenn - wie vorgeschlagen - die Schweißnaht im Bereich des zur Nut hin offenen Endes des Spalts angeordnet wird. Denn dieser Bereich ist über die Nut leicht zugänglich.According to a preferred embodiment of the invention, a weld seam is arranged in the area of the gap, preferably in the area of the end of the gap that is open towards the groove, for connecting the profile sections delimiting the gap. The weld seam can in particular be a laser weld seam, since laser weld seams can be carried out particularly precisely. The gap also makes it easier to set the weld seam. This applies in particular if—as proposed—the weld seam is arranged in the region of the end of the gap that is open towards the groove. Because this area is easily accessible via the groove.

Das heißt, dass die Schweißnaht vorzugsweise in einem Bereich angeordnet wird, der einen Nutgrund der Nut bildet. Bei einer entsprechenden Anordnung der Schweißnaht wird zudem ein besonders wirksamer Schutz gegen ein unerwünschtes Aufbiegen der Nut bewirkt.This means that the weld seam is preferably arranged in an area that forms a groove base of the groove. With a corresponding arrangement of the weld seam, a particularly effective protection against undesired bending of the groove is also achieved.

Vorteilhafterweise ist die Blechstärke des Metallblechs, aus dem das Metallprofil hergestellt ist, zumindest im Bereich eines den Spalt begrenzenden Profilabschnitts verringert. Der Bereich mit verringerter Blechstärke kann dann zur Ausbildung des Spalts genutzt werden. Vorteilhafterweise werden zur Ausbildung des Spalts zwei Bereiche mit verringerter Blechstärke in Überdeckung gebracht, so dass eine größere Spaltbreite erzielbar ist.Advantageously, the sheet metal thickness of the metal sheet from which the metal profile is made is reduced, at least in the region of a profile section delimiting the gap. The area with reduced sheet thickness can then be used to form the gap. Advantageously used for training of the gap, two areas with a reduced sheet thickness are overlapped so that a larger gap width can be achieved.

Die Verwendung eines Metallblechs mit bereichsweise verringerter Blechstärke zur Ausbildung des Spalts besitzt den Vorteil, dass kein materialabtragendes Verfahren eingesetzt werden muss. Denn in der Regel sind Metallbleche zur Herstellung eines Metallprofils beschichtet, so dass ein materialabtragendes Verfahren auch zum Abtragen der Beschichtung führen würde, die anschließend erneuert werden müsste. Wird jedoch ein Metallblech verwendet, das bereits Bereiche mit verringerter Blechstärke besitzt, kann dieser zusätzliche Arbeitsschritt entfallen.The use of a metal sheet with a reduced sheet thickness in some areas to form the gap has the advantage that no material-removing process has to be used. Because as a rule, metal sheets are coated for the production of a metal profile, so that a material-removing process would also lead to the removal of the coating, which would then have to be renewed. However, if a metal sheet is used that already has areas with a reduced sheet thickness, this additional work step can be omitted.

Die bereichsweise Verringerung der Blechstärke wird vorzugsweise durch plastisches Verformen, insbesondere durch Strecken, des Metallblechs erreicht. Beim Strecken bleibt eine etwaige Beschichtung des Metallblechs, wie beispielsweise eine als Rostschutz dienende Zinkbeschichtung, grundsätzlich erhalten, so dass weiterhin ein effektiver Rostschutz gewährleistet ist.The area-wise reduction in sheet thickness is preferably achieved by plastic deformation, in particular by stretching, of the sheet metal. Stretching leaves any coating on the metal sheet, such as a zinc coating serving as rust protection, basically retained, so that effective rust protection is still guaranteed.

Vorzugsweise beträgt die Blechstärke des Metallblechs zur Herstellung des Metallprofils 1-3 mm, weiterhin vorzugsweise 1-2 mm, beispielsweise 1,5 mm.The sheet metal thickness of the metal sheet for producing the metal profile is preferably 1-3 mm, more preferably 1-2 mm, for example 1.5 mm.

Vorteilhafterweise ist die Blechstärke des Metallblechs zumindest im Bereich eines den Spalt begrenzenden Profilabschnitts um mindestens 10% verringert. Denn dies ermöglicht die Ausbildung eines ausreichend breiten Spalts. Wird beispielsweise ein Metallblech mit einer Blechstärke von 1,5 mm zur Herstellung des Metallprofils verwendet, beträgt die Spaltbreite bevorzugt mindestens 0,4 mm.Advantageously, the sheet metal thickness of the metal sheet is reduced by at least 10%, at least in the region of a profile section delimiting the gap. Because this allows the formation of a sufficiently wide gap. If, for example, a metal sheet with a sheet thickness of 1.5 mm is used to produce the metal profile, the gap width is preferably at least 0.4 mm.

Bevorzugt ist die Nut im Querschnitt symmetrisch ausgebildet. Die zur Herstellung eines Verbundprofils erforderliche kraft- und/oder formschlüssige Verbindung des Metallprofils mit einem Isolierprofil kann in diesem Fall durch gleichmäßiges Andrücken bzw. Zusammendrücken der nutbegrenzenden Profilabschnitte bewirkt werden.The groove is preferably formed symmetrically in cross section. In this case, the non-positive and/or positive connection of the metal profile to an insulating profile, which is necessary for the production of a composite profile, can be brought about by uniformly pressing on or compressing the profile sections that delimit the groove.

Weiterhin bevorzugt besitzt die Nut eine im Wesentlichen dreieckige, trapezförmige oder rechteckige Querschnittsform. Bei einer im Wesentlichen dreieckigen oder trapezförmigen Querschnittsform weitet sich vorzugsweise die Nut in Richtung der Öffnung, um das Einsetzen eines Isolierprofils in die Nut zu erleichtern.Furthermore, the groove preferably has an essentially triangular, trapezoidal or rectangular cross-sectional shape. In the case of a substantially triangular or trapezoidal cross-sectional shape, the groove preferably widens in the direction of the opening in order to facilitate the insertion of an insulating profile into the groove.

Da das Metallprofil bei der Herstellung eines Kraft- und/oder Formschlusses mit einem Isolierprofil im Bereich eines nutbegrenzenden Profilabschnitts plastisch verformt wird, kann sich die Querschnittsform der Nut ändern. Beispielsweise kann eine ursprünglich trapezförmige Nut anschließend eine rechteckige Querschnittsform aufweisen. Das heißt, dass die Querschnittsform der Nut eines erfindungsgemäßen Metallprofils im Wesentlichen davon abhängt, ob eine kraft- und/oder formschlüssige Verbindung mit einem Isolierprofil bereits hergestellt worden ist oder nicht.Since the metal profile is plastically deformed in the production of a non-positive and/or positive connection with an insulating profile in the region of a profile section that delimits the groove, the cross-sectional shape of the groove can change. For example, an originally trapezoidal groove can subsequently have a rectangular cross-sectional shape. This means that the cross-sectional shape of the groove of a metal profile according to the invention essentially depends on whether a non-positive and/or positive connection with an insulating profile has already been established or not.

In Weiterbildung der Erfindung wird vorgeschlagen, dass die Nut seitlich begrenzende Profilabschnitte an ihren freien Enden eine Bördelung oder einen Falz besitzen. Über die Bördelung bzw. den Falz wird eine höhere Steifigkeit der freien Enden der die Nut seitlich begrenzenden Profilabschnitte erreicht, da hier das Material doppelt liegt oder zumindest eine aussteifende Profilierung besitzt. Ferner vereinfacht der Bereich der Bördelung bzw. des Falzes die Herstellung eines Formschlusses, da dieser derart um eine Außenkontur eines Isolierprofils legbar ist, dass er diese hintergreift.In a further development of the invention, it is proposed that profile sections that laterally delimit the groove have a beading or a fold at their free ends. The flanging or the fold increases the rigidity of the free ends of the profile sections laterally delimiting the groove, since the material is doubled here or at least has a stiffening profile. Furthermore, the area of the beading or the fold simplifies the production of a form fit, since it can be placed around an outer contour of an insulating profile in such a way that it engages behind it.

Zur Optimierung des Kraft- und/oder Formschlusses zwischen dem Metallprofil und einem Isolierprofil wird vorgeschlagen, dass mindestens ein die Nut begrenzender Profilabschnitt eine nutseitige Oberfläche besitzt, die zumindest bereichsweise mit einer Strukturierung, beispielsweise in Form einer Rändelung, versehen ist. Die Strukturierung wirkt einer Relativbewegung des in der Nut aufgenommenen Isolierprofils gegenüber dem Metallprofil in Quer- und/oder in Längsrichtung (Schubrichtung) entgegen. Derartige Relativbewegungen sind unerwünscht, da sie den Verbund zwischen dem Metallprofil und dem Isolierprofil beeinträchtigen und in der Folge die mechanische Festigkeit des Verbundprofils herabsetzen.In order to optimize the non-positive and/or positive connection between the metal profile and an insulating profile, it is proposed that at least one profile section delimiting the groove has a groove-side surface which is provided with a structure, for example in the form of knurling, at least in certain areas. The structuring counteracts a relative movement of the insulating profile accommodated in the groove in relation to the metal profile in the transverse and/or longitudinal direction (thrust direction). Such relative movements are undesirable since they impair the bond between the metal profile and the insulating profile and consequently reduce the mechanical strength of the composite profile.

Gemäß der Erfindung bilden die den Spalt begrenzenden Profilabschnitte einen Steg aus, der mittig in Bezug auf die Nut angeordnet ist. Gleiches gilt entsprechend für den zur Nut hin offenen Spalt. Der Steg verleiht dem Metallprofil eine größere Tiefe und demzufolge eine höhere Formsteifigkeit in Tiefenrichtung. Die Tiefe wird senkrecht zur Länge und Breite des Metallprofils gemessen.According to the invention, the profile sections delimiting the gap form a web which is arranged centrally in relation to the groove. The same applies accordingly to the gap open towards the groove. The web gives the metal profile greater depth and consequently greater dimensional stability in the direction of depth. The depth is measured perpendicular to the length and width of the metal profile.

Des Weiteren bevorzugt sind die den Spalt begrenzenden Profilabschnitte über weitere Profilabschnitte verbunden. Auch diese Maßnahme führt zu einer erhöhten Formsteifigkeit des Metallprofils. Vorzugsweise bilden die weiteren Profilabschnitte mindestens einen Flansch aus, der weiterhin vorzugsweise senkrecht zum Steg angeordnet ist. Ein Flansch kann der Ausbildung eines Anschlags dienen, den es regelmäßig an einem Fenster- oder Türprofil auszubilden gilt. Alternativ oder ergänzend kann ein Flansch zur Ausbildung einer seitlichen Nut genutzt werden, in welche ein Dichtungsprofil oder dergleichen einsetzbar ist. Analog zum Steg können auch im Bereich eines Flansches die weiteren Profilabschnitte zumindest bereichsweise aufeinander liegen. Alternativ können die weiteren Profilabschnitte aber auch einen Hohlraum begrenzen, wodurch sich die Formsteifigkeit des Metallprofils, insbesondere aufgrund der größeren Tiefe, nochmals erhöht.Furthermore, the profile sections delimiting the gap are preferably connected via further profile sections. This measure also leads to increased dimensional stability of the metal profile. The further profile sections preferably form at least one flange, which is also preferably arranged perpendicularly to the web. A flange can be used to form a stop that must be regularly formed on a window or door profile. Alternatively or additionally, a flange can be used to form a lateral groove into which a sealing profile or the like can be inserted. Analogously to the web, the further profile sections can also lie on top of one another at least in regions in the area of a flange. Alternatively, however, the further profile sections can also delimit a cavity, as a result of which the dimensional stability of the metal profile is further increased, in particular due to the greater depth.

Da das erfindungsgemäße Metallprofil vorrangig der Herstellung eines Verbundprofils dient, wird ferner ein Verbundprofil mit mindestens einem erfindungsgemäßen Metallprofil vorgeschlagen. Das vorgeschlagene Verbundprofil umfasst darüber hinaus ein Isolierprofil, das bereichsweise in der Nut des Metallprofils aufgenommen und kraft- und/oder formschlüssig mit dem Metallprofil verbunden ist. Das vorgeschlagene Verbundprofil zeichnet sich durch einen stabilen Verbund sowie eine hohe Maßhaltigkeit aus. Beides ist auf die Verwendung mindestens eines erfindungsgemäßen Metallprofils zurückzuführen.Since the metal profile according to the invention is primarily used to produce a composite profile, a composite profile with at least one metal profile according to the invention is also proposed. The proposed composite profile also includes an insulating profile that is accommodated in certain areas in the groove of the metal profile and is connected to the metal profile in a non-positive and/or positive manner. The proposed composite profile is characterized by a stable bond and high dimensional accuracy. Both are due to the use of at least one metal profile according to the invention.

Vorzugsweise umfasst das Verbundprofil mindestens zwei erfindungsgemäße Metallprofile, die durch das Isolierprofil thermisch getrennt werden. Das Isolierprofil ist hierzu zwischen den beiden Metallprofilen angeordnet. Die Querschnittsform der beiden Metallprofile kann unterschiedlich ausgebildet sein, wobei jedoch beide Metallprofile einen eine Nut ausbildenden Profilquerschnitt zur Aufnahme des Isolierprofils besitzen. Das Isolierprofil weist vorzugsweise an mindestens einem Ende eine Außenkontur auf, die ein Hintergreifen eines Profilabschnitts eines Metallprofils ermöglicht.The composite profile preferably comprises at least two metal profiles according to the invention, which are thermally separated by the insulating profile. For this purpose, the insulating profile is arranged between the two metal profiles. The cross-sectional shape of the two metal profiles can be designed differently, but both metal profiles have a profile cross-section forming a groove for receiving the insulating profile. The insulating profile preferably has an outer contour on at least one end, which enables a profile section of a metal profile to be gripped from behind.

Ferner wird ein Verfahren zur Herstellung eines erfindungsgemäßen Metallprofils vorgeschlagen, bei dem das Metallprofil durch Umformen, insbesondere Rollformen, aus einem Metallblech hergestellt wird. Das Verfahren zeichnet sich dadurch aus, dass zur Ausbildung des Spalts die Blechstärke des Metallblechs vor dem Umformen, insbesondere Rollformen, in zumindest einem Bereich verringert wird. Das heißt, dass zur Herstellung des Metallprofils ein Metallblech verwendet wird, das mindestens zwei unterschiedliche Blechstärken besitzt. Die Verwendung eines derartigen Metallblechs vereinfacht die Ausbildung des zur Nut hin offenen Spalts, da die Blechstärkenverringerung automatisch spaltbildend wirkt, wenn zwei Profilabschnitte aufeinander gelegt werden. Dies gilt insbesondere, wenn nicht nur ein spaltbegrenzender Profilabschnitt bereichsweise eine verringerte Blechstärke aufweist, sondern beide sich am Spalt gegenüber liegenden Profilabschnitte eine Blechstärkenverringerung aufweisen. Hierzu müssen die Bereiche mit verringerter Blechstärke der jeweiligen Profilabschnitte beim Umformen, insbesondere Rollformen, lediglich in Überdeckung gebracht werden.Furthermore, a method for producing a metal profile according to the invention is proposed, in which the metal profile is produced from a metal sheet by forming, in particular roll forming. The method is characterized in that, to form the gap, the sheet metal thickness of the metal sheet is reduced in at least one area before forming, in particular roll forming. This means that a metal sheet is used to produce the metal profile, which has at least two different sheet thicknesses. The use of such a metal sheet simplifies the formation of the gap open towards the groove, since the sheet thickness reduction automatically has the effect of forming a gap when two profile sections are placed one on top of the other. This applies in particular if not only a gap-limiting profile section has a reduced sheet thickness in some areas, but both profile sections lying opposite one another at the gap have a sheet thickness reduction. For this purpose, the areas with reduced sheet thickness of the respective profile sections only have to be brought into overlap during forming, in particular roll forming.

Erfindungsgemäß wird die Blechstärke des Metallblechs, die vorzugsweise 1-3 mm, weiterhin vorzugsweise 1-2 mm, beispielsweise 1,5 mm, beträgt, durch plastisches Verformen, insbesondere durch Strecken, in zumindest einem Bereich verringert. Das heißt, dass, im Unterschied zu einem spanabhebenden Verfahren, kein Material abgetragen wird. Auf diese Weise bleibt eine etwaige bereits vorhandene Beschichtungen des Metallblechs, beispielsweise eine als Rostschutz dienende Zinkbeschichtung, weitgehend erhalten, so dass weiterhin ein effektiver Rostschutz gewährleistet ist. Das Strecken geht zwar mit einer Verringerung der Beschichtungsstärke einher, dies hat im Fall einer Zinkbeschichtung jedoch den Vorteil, dass diese nicht mehr entfernt werden muss, um eine Schweißnaht zu setzen. Dadurch kann das Verfahren zur Herstellung eines erfindungsgemäßen Metallprofils weiter vereinfacht werden.According to the invention, the sheet metal thickness of the metal sheet, which is preferably 1-3 mm, more preferably 1-2 mm, for example 1.5 mm, is reduced in at least one area by plastic deformation, in particular by stretching. This means that, in contrast to a machining process, no material is removed. In this way, any existing coatings on the sheet metal, for example a zinc coating serving as rust protection, are largely retained, so that effective rust protection is still ensured. Although stretching is accompanied by a reduction in the thickness of the coating, this has the advantage in the case of a zinc coating that it no longer has to be removed in order to make a weld. As a result, the method for producing a metal profile according to the invention can be further simplified.

Wird ein Metallblech verwendet, das mit einer Zinkbeschichtung versehen ist, handelt es sich vorzugsweise um ein kontinuierlich schmelztauchveredeltes (früher: bandverzinktes) Stahlblech.If a metal sheet is used that is provided with a zinc coating, it is preferably a continuously hot-dip refined (formerly: strip-galvanized) steel sheet.

Weiterhin bevorzugt wird die Blechstärke des Metallblechs in zumindest einem Bereich um mindestens 10% verringert. Ausgehend von den vorstehend genannten bevorzugten Blechstärken liegt demnach die verringerte Blechstärke zwischen 0,9 und 2,7 mm bzw. zwischen 0,9 und 1,8 mm. Bei einer Ausgangsblechstärke von beispielsweise 1,5 mm kann die verringerte Blechstärke 1,3 mm betragen.Furthermore, the sheet thickness of the metal sheet is preferably reduced by at least 10% in at least one area. Based on the preferred sheet thicknesses mentioned above, the reduced sheet thickness is between 0.9 and 2.7 mm or between 0.9 and 1.8 mm. With an initial sheet thickness of 1.5 mm, for example, the reduced sheet thickness can be 1.3 mm.

Bezogen auf den Querschnitt des Metallblechs kann die Blechstärkenverringerung sowohl symmetrisch als auch asymmetrisch ausgebildet sein.In relation to the cross-section of the sheet metal, the reduction in sheet thickness can be embodied both symmetrically and asymmetrically.

Ausführliche Beschreibung der ZeichnungenDetailed description of the drawings

Das in der Fig. 1 im Querschnitt dargestellte Metallprofil 1 ist durch Umformen aus einem Metallblech hergestellt worden und weist einen im Wesentlichen T-förmigen Profilquerschnitt auf. Die beiden Enden des Metallblechs bilden dabei seitliche Begrenzungen einer Nut 3 aus, die vorliegend im Querschnitt trapezförmig ist. Der trapezförmige Querschnitt der Nut 3 erleichtert das Einsetzen eines Isolierprofils 2, um zu einem Verbundprofil gemäß der Fig. 3 oder der Fig. 4 zu gelangen.That in the 1 The metal profile 1 shown in cross section has been produced by forming a metal sheet and has an essentially T-shaped profile cross section. The two ends of the sheet metal form lateral delimitations of a groove 3, which is trapezoidal in cross section in the present case. The trapezoidal cross section of the groove 3 facilitates the insertion of an insulating profile 2 to a composite profile according to the 3 or the 4 to get.

Die die Nut 3 seitlich begrenzenden Profilabschnitte 3.1, 3.4 sind an ihren Enden zur Ausbildung eines nutseitigen Falzes 6 umgelegt. Der Falz 6 erleichtert die Herstellung einer formschlüssigen Verbindung zwischen dem Metallprofil 1 und einem Isolierprofil 2, da der Bereich des Falzes 6 derart um eine endseitige Außenkontur des Isolierprofils 2 gelegt werden kann, dass der Falz 6 die Außenkontur hintergreift.The profile sections 3.1, 3.4 laterally delimiting the groove 3 are folded over at their ends to form a fold 6 on the groove side. The fold 6 facilitates the production of a form-fitting connection between the metal profile 1 and an insulating profile 2, since the area of the fold 6 can be placed around an end outer contour of the insulating profile 2 in such a way that the fold 6 engages behind the outer contour.

Die die Nut 3 begrenzenden Profilabschnitte 3.1, 3.2, 3.3, 3.4 des in der Fig. 1 dargestellten Metallprofils 1 weisen auf ihrer nutseitigen Oberfläche eine Strukturierung 7 in Form einer Rändelung auf (siehe gestrichelte Linie, welche den Bereich der Rändelung verdeutlichen soll). Die Rändelung wirkt Relativbewegungen eines in der Nut 3 aufgenommenen und mit dem Metallprofil 1 kraft- und/oder formschlüssig verbundenen Isolierprofils 2 gegenüber dem Metallprofil 1 entgegen.The profile sections 3.1, 3.2, 3.3, 3.4 delimiting the groove 3 in the 1 The metal profile 1 shown has a structuring 7 in the form of knurling on its groove-side surface (see dashed line, which is intended to clarify the region of the knurling). The knurling counteracts relative movements of an insulating profile 2 that is received in the groove 3 and is connected to the metal profile 1 in a non-positive and/or positive manner in relation to the metal profile 1 .

Die die Nut 3 begrenzenden Profilabschnitte 3.1, 3.2, 3.3, 3.4 umfassen die Profilabschnitte 3.2, 3.3, die einen Nutgrund der Nut 3 ausbilden. An die den Nutgrund ausbildenden Profilabschnitte 3.2, 3.3 schließen sich Profilabschnitte 5.1, 5.2 an, die bereichsweise, nämlich in einem gemeinsamen Kontaktbereich 4, aufeinander liegen und somit einen Steg 5 ausbilden. Außerhalb des gemeinsamen Kontaktbereichs 4 begrenzen die Profilabschnitte 5.1, 5.2 einen Spalt 8, der zur Aufnahme einer Schweißnaht 10 zur Nut 3 hin offen ist (in den Fig. 1 und 2 ist das Metallprofil 1 bereits mit gesetzter Schweißnaht 10 dargestellt).The profile sections 3.1, 3.2, 3.3, 3.4 delimiting the groove 3 comprise the profile sections 3.2, 3.3, which form a groove base of the groove 3. The profile sections 3.2, 3.3 forming the groove base are followed by profile sections 5.1, 5.2, which in some areas, namely in a common contact area 4, lie one on top of the other and thus form a web 5. Outside the common contact area 4, the profile sections 5.1, 5.2 delimit a gap 8, which is open towards the groove 3 for receiving a weld seam 10 (in the Figures 1 and 2 the metal profile 1 is already shown with the weld seam 10 set).

An die den Steg 5 ausbildenden Profilabschnitte 5.1, 5.2 schließen sich weitere Profilabschnitte 9.1, 9.2, 9.3 an, welche einen Flansch 9 ausbilden, der senkrecht zum Steg 5 angeordnet sind. Die Profilabschnitte 9.1, 9.2, 9.3 liegen ebenfalls aufeinander, so dass durch das doppelt liegende Material eine hohe Formsteifigkeit erreicht wird.The profile sections 5.1, 5.2 forming the web 5 are followed by further profile sections 9.1, 9.2, 9.3, which form a flange 9 which is arranged perpendicularly to the web 5. The profile sections 9.1, 9.2, 9.3 also lie one on top of the other, so that a high degree of dimensional stability is achieved by the material lying twice.

Wie der Fig. 2 zu entnehmen ist, weist das Metallblech des Metallprofils 1 im Bereich der den Spalt 8 begrenzenden Profilabschnitte 5.1, 5.2 eine verringerte Blechstärke S' auf. Die Blechstärkenverringerung führt automatisch zur Ausbildung des Spalts 8. In dem Ausführungsbeispiel der Fig. 2 beträgt die Blechstärke S 1,5 mm. Im Bereich des Spalts 8 weist das Metallblech eine Blechstärke S' von 1,3 mm auf. Da die Blechstärkenverringerung asymmetrisch vorgenommen worden ist, kommt sie in Gänze der Spaltbildung zugute, so dass die Breite B des Spalts 8 0,4 mm beträgt. Die Länge L des Spalts 8 beträgt vorliegend 4 mm.Again 2 As can be seen, the sheet metal of the metal profile 1 has a reduced sheet thickness S' in the region of the profile sections 5.1, 5.2 delimiting the gap 8. The sheet thickness reduction automatically leads to the formation of the gap 8. In the embodiment of 2 the sheet thickness S is 1.5 mm. In the area of the gap 8, the sheet metal has a sheet thickness S' of 1.3 mm. Since the sheet thickness reduction has been carried out asymmetrically, it benefits the gap formation in its entirety, so that the width B of the gap 8 is 0.4 mm. The length L of the gap 8 is 4 mm in the present case.

Der Fig. 2 ist weiterhin deutlich die im Spalt 8 angeordnete Schweißnaht 10 zu entnehmen. Die Anordnung der Schweißnaht 10 erfolgt im Bereich des Nutgrundes der Nut 3, so dass die Schweißnaht 10 besonders wirksam einem unerwünschten Aufbiegen der Nut 3 entgegen wirkt. Alternativ zur Verschweißung kann auch eine Verklebung der beiden spaltbegrenzenden Profilabschnitte 5.1, 5.2 vorgesehen werden. Der Klebstoff wird hierzu ebenfalls im Spalt 8 angeordnet.The 2 the weld seam 10 arranged in the gap 8 can also be clearly seen. The weld seam 10 is arranged in the area of the bottom of the groove 3, so that the weld seam 10 counteracts undesired bending of the groove 3 particularly effectively. As an alternative to welding, the two gap-limiting profile sections 5.1, 5.2 can also be glued together. The adhesive is also arranged in the gap 8 for this purpose.

Eine bevorzugte Ausführungsform eines unter Verwendung eines erfindungsgemäßen Metallprofils 1 hergestellten Verbundprofils ist der Fig. 3 zu entnehmen. Das Verbundprofil umfasst das Metallprofil 1 der Fig. 1 sowie ein zweites Metallprofil 1, das sich von dem ersten Metallprofil 1 lediglich dadurch unterscheidet, dass es einen Flansch 9 mit geringerer Breite besitzt. Zur thermischen Trennung ist zwischen den beiden Metallprofilen 1 ein Isolierprofil 2 angeordnet. An seinen beiden Enden besitzt das Isolierprofil 2 jeweils eine Außenkontur, die in der Nut 3 der jeweiligen Metallprofils 1 aufgenommen und mit diesem kraft- und/oder formschlüssig verbunden ist.A preferred embodiment of a composite profile produced using a metal profile 1 according to the invention is 3 refer to. The composite profile includes the metal profile 1 of 1 and a second metal profile 1, which differs from the first metal profile 1 only in that it has a flange 9 with a smaller width. An insulating profile 2 is arranged between the two metal profiles 1 for thermal separation. At each of its two ends, the insulating profile 2 has an outer contour which is in the groove 3 of the respective metal profile 1 and is connected to it in a non-positive and/or positive manner.

Das in der Fig. 3 dargestellte Verbundprofil dient insbesondere der Herstellung eines Fenster- oder Türelements. Ein solches Fenster- oder Türelement ist beispielhaft in der Fig. 4 dargestellt. Zur Aufnahme eines Füllelements 12, das vorliegend aus eine Glasscheibe besteht, sind Dichtungsprofile 11 vorgesehen. Bei dem ersten Metallprofil 1, das den breiten Flansch 9 aufweist, sind die Dichtungsprofile 11 im Bereich des Stegs 5 angeordnet und am Flansch 9 abgestützt. Weitere Dichtungsprofile 11 sind auf Glashalteprofile 13 gesteckt, die beidseits des zweiten Metallprofils 1 angeordnet sind. Die Glashalteprofile 13 schließen im Wesentlichen bündig mit dem Flansch 9 des zweiten Metallprofils 1 ab und deren Breite ist derart gewählt, dass die Ansichtsbreite des zweiten Metallprofils 1 einschließlich der Glashalteprofile 13 der Ansichtsbreite des Flanschs 9 des ersten Metallprofils 1 entspricht.That in the 3 composite profile shown is used in particular for the production of a window or door element. Such a window or door element is exemplified in 4 shown. Sealing profiles 11 are provided to accommodate a filling element 12, which in this case consists of a pane of glass. In the case of the first metal profile 1, which has the wide flange 9, the sealing profiles 11 are arranged in the region of the web 5 and are supported on the flange 9. Further sealing profiles 11 are placed on glass holding profiles 13 which are arranged on both sides of the second metal profile 1 . The glazing profiles 13 end essentially flush with the flange 9 of the second metal profile 1 and their width is chosen such that the face width of the second metal profile 1 including the glazing profile 13 corresponds to the face width of the flange 9 of the first metal profile 1 .
