- the heat-insulating profile according to the invention has the advantage that the plastic material of the elevations can easily penetrate into the recesses of a knurling, which can be provided in those areas of the clamping fists of the metal profiles, which come into contact with the clamping surfaces of the heat-insulating profile.
- At least one attachment lug of the thermal insulation profile has a wedge shape, wherein the wedge shape tapers in the first direction toward the end of the thermal insulation profile.
- the clamping surfaces are arranged at an angle to each other, which can facilitate the centering of the thermal insulation profile in the clamping fists of the metal profiles in the production of a composite profile.
- At least one attachment lug of the thermal insulation profile has a wedge shape, widening the wedge shape in the first direction towards the end of the heat-insulating profile.
- the clamping surfaces are arranged at an angle to each other, but in addition forms a positive connection between the mounting lugs of the thermal insulation profile and the metal profiles.
- At least one attachment lug of the thermal insulation profile has a clamping surface which is curved and widens the attachment lug in a second direction perpendicular to the first direction.
- a positive connection between the mounting lugs of the thermal insulation profiles and the metal profiles because the Klemmfäuste the metal profiles surround the spherically shaped clamping surfaces of the attachment lugs.

- the at least one attachment lug further comprises a centering surface which is oriented perpendicular to the first direction and represents the end of the heat-insulating profile in the first direction, wherein the centering surface comprises a convex or concave indentation.
- the centering surface may be curved, while according to an alternative preferred embodiment, the centering surface comprises two centering surface sections arranged at an angle to one another. In this case, the curved geometry of the centering allows a more effective centering, since the mounting lug "searches" the right position when rolling.
- At least one retaining surface extending substantially perpendicularly to the first direction is provided between the fastening projection and the central web of the thermal insulation profile.
- the provision of at least one retaining surface offers the advantage that the clamping lug of the associated metal profile surrounding the fastening lug embraces the fastening lug in a form-fitting manner and therefore enables increased strength of the composite profile in the first direction.
- the elevations have at least one clamping surface in the Essentially sharp cross-sectional shape.
- the cross-sectional shape of the surveys can be designed. The sharper the elevations run, the harder the material of the thermal insulation profile can be selected. If a material with a lower hardness is used, then the elevations according to an alternative, preferred embodiment of the invention may have a substantially spherical shape.
- the relative height of the protrusions above the groove bottom of the groove-shaped recesses increases in the first direction and with increasing distance to the end of the attachment lug. In this way, there is more material at that position in the transition region to the central web on which acts when forming the metal profile, the largest force on the attachment approach.

- the composite profile according to the invention is preferably designed and tuned to the geometry of the thermal insulation profile, that the clear distance in the clamping lug clampingly embracing the fastening lug is less than the corresponding standard dimension of the attachment lug.
- a knurling is provided on those parts of the clamping fists of the metal profiles, which contacts the at least one clamping surface of the fastening lug.
- a part of a thermal insulation profile 10 is shown. Shown in detail are a mounting lug 12 and a part of the central web 14.
- the central web 14 may be configured in any desired manner and, for example, in have a direction perpendicular to the longitudinal extent of the central web 14 extending formations to reduce the radiation exchange between the metal profiles.
- the thermal insulation profile 10 serves the thermal separation of a composite profile for facades, windows and doors, which consists of metal profiles which are thermally separated from each other by the heat insulation profiles according to the invention are located between the metal profiles.
- the heat-insulating profile consists essentially of plastic, but depending on the desired application, additional materials can also be used in addition. So it is possible to use glass fiber reinforced plastic. If the thermal insulation profile is to be used in a composite profile which has to meet fire protection requirements, it is also possible, for example, for a metal profile to be embedded in the interior of the plastic material, which in the event of fire, if the plastic of the thermal insulation profile melts, connects the metal profiles to each other at least for a predetermined period of time. In the same way, it is also possible to attach further elements to the central web of the thermal insulation profile, e.g. Elements that consist of energy-consuming materials or that foam up under the influence of heat.
- thermal insulation profile 10 has a mounting lug 12 which is widened relative to the central web 14. In the transition region between the central web 14 and the attachment lug 12 while retaining surfaces 16 are provided, which may have the function in the attachment of the attachment lug 12 on a metal profile, from Metal profile to be at least partially encompassed to produce a positive connection.
- two clamping surfaces 18 are provided, which are clamped in the production of a composite profile in the clamping fists of the metal profile.
- the clamping surfaces 18 are provided with a plurality of elevations 20 and groove-shaped depressions 22.
- the elevations 20 and groove-shaped depressions 22 extend in the longitudinal direction of the heat-insulating profiles and can therefore be easily produced when extruding the heat-insulating profiles.
- the elevations 20 can be deformed during the production of the composite profile and in particular when the clamping fists are rolled around the fastening lugs 12 as part of a forming process. Due to the easier deformability of the elevations 20, numerous advantages can be achieved. On the one hand, the elasticity of the attachment lug is increased, whereby the tolerance compensation between the heat-insulating profile and the associated metal profile can be improved.
- the shear strength of the connection between the thermal insulation profile and the associated metal profile can be improved by the plastic material of the thermal insulation profile can easily penetrate into depressions on the contact surfaces of the metal profiles, which is produced either by a knurling or by roughening by blasting the metal profiles.
- the mounting lug By making the mounting lug more elastic by providing the grooves, materials of higher strength, which often also have a higher hardness, can be used to produce the heat-insulating profile. In this way, by providing the grooves, the range of materials can be extended. Another effect, which is not in the foreground, is a slightly improved thermal insulation, as due to the groove-shaped depressions, the contact surface between the attachment lug and the associated clamping fist of the metal profile is slightly reduced compared to a full-surface investment.
- a clamping surface 18a is provided with elevations 20 and groove-shaped recesses 22, while the other clamping surface 18b is configured as a flat surface without elevations and groove-shaped depressions.
- the embodiment according to Fig. 3 differs from the one after Fig. 2 to the effect that the attachment lug is widened only towards one side with respect to the central web 14, namely the side on which the clamping surface 18a with the elevations 20 and groove-shaped recesses 22 is located. Accordingly, a holding surface 16 is provided only on this one side.
- Fig. 2 and 3 also realize the advantages of the invention, since it is sufficient depending on the choice of material, to provide tolerance compensation between the thermal insulation profile and the metal profile only on one side.
- Fig. 4 shows, in combination, several additional features, which, however, can each be realized separately in a thermal insulation profile according to the invention. These are on the one hand the provision of a centering surface 24, furthermore the geometry of the elevations 20 and last but not least the provision of a different height of the elevations. Furthermore, in the Fig. 4 shown in the form of dashed lines the position of the clamping fists of the associated metal profile after forming.
- the centering surface 24 is in the embodiment according to Fig. 4 is formed of two Zentrier vomabitesen 24a and 24b, which in an area 24c, which may be provided with a rounding, adjacent to each other.
- the function of the centering surface 24 is that in the context of the production of a composite profile, the heat-insulating profile itself pre-adjusted before the rolling of the clamping fists and thus takes place an alignment in the encompassing metal part.
- Fig. 4 shown that 20 different geometries can be selected for the surveys.
- elevations 20a substantially in the form of a tapered, tooth-shaped profile, while the opposite clamping surface is provided with projections 20b, which are rounded and together with the associated recesses form a wavy surface.
- the choice of the geometry of the elevations and associated groove-shaped depressions depends on the material properties of the thermal insulation profile. The harder the plastic material used of the thermal insulation profile or the greater the desired material deformation should be, the more pointed the elevations 20 can be configured, up to the relatively sharp-edged sawtooth shape, which is shown schematically with the elevations 20a. However, if the plastic material is of lesser hardness, then the geometry with wave-shaped elevations 20b offers itself.
- Fig. 4 Beyond the pure geometry of the elevations 20a and 20b is in Fig. 4 also shown that the height of the elevations 20 in the direction of the central web 14 increases continuously.
- the fact is taken into account that in the transition region between the clamping surface 18 and the support surface 16 the greatest forces when forming the metal profile act, whereby here the largest collection of material is provided.
- FIG. 7 an embodiment similar to Fig. 6 with a concave centering surface 24, but consisting of two Zentrier vomabitesen 24 a and 24 b analogous to that in Fig. 4 illustrated embodiment.
- Fig. 8 and Fig. 9 shows in each case a fastening lug 12, which is designed conically.
- the clamping surfaces 18 are not parallel to each other but are at an angle to each other.
- the positions of the clamping shells of the metal shells marked with reference numeral 26 are also at an angle to each other after the composite profile has been produced.
- the embodiments according to Fig. 8 and 9 differ in that after Fig. 8 the attachment lug 12 expands towards the end, while in the embodiment according to Fig. 9 the attachment approach to the end of the thermal insulation profile 10 tapers. Both variants are selected depending on the Umformijin and can be specifically used to the effect that after forming the metal profiles and producing the composite profile as uniform as possible force distribution between the clamping fist of the metal profile and the thermal insulation 10.
- the embodiment according to Fig. 10 has similarities with the one Fig. 3 on, by a smooth surface is provided in the region of the clamping surface 18 b and there is no holding surface in the transition to the central web.
- the clamping surface 18a after Fig. 10 has a rounded shape, so that the thermal insulation profile 10 after Fig. 10 has a round clamping head.
- the clamping surface 18a is according to the invention again provided with elevations 20 and groove-shaped depressions 22. After producing the composite profile, the elevations 20 are compressed so far that again results in the contour indicated by a broken line and reference numeral 26.
- Fig. 11 complements the embodiment Fig. 10 to the effect that in addition between the elevations 20a and 20b, a recess 22a is arranged, which is designed as a centering groove.
- This centering groove designed wider and deeper than the other groove-shaped depressions serves to receive a centering nose, which is provided on the clamping fist, which surrounds the fastening projection 12 after the production of the composite profile.
- the provision of a centering offers as a simple measure to easy positioning and Centering of the thermal insulation profile to produce relative to the metal profile.
- each is the mounting situation of in Fig. 1 shown thermal insulation profiles in a generally with reference numeral 30 and only partially shown metal half-shell of a composite profile shown.
- the in Fig. 13 Profile shown preferred for a thermal insulation profile such as for example Fig. 1 used
- the in Fig. 12 illustrated Klemmfaust 32 of a metal profile 30 preferably for a thermal insulation profile according to Fig. 2 is used, in which only on one of the two sides of the attachment lug 12 is provided a clamping surface 18a with elevations and groove-shaped depressions, while the other clamping surface 18b is designed as a flat surface without elevations and groove-shaped depressions.
- the in Fig. 13 shown section of a metal profile 30 has, in contrast to the in Fig. 12 variant shown an additional hollow chamber 34, in the same way but also in the metal profile after Fig. 12 can be realized.
- the clamping fist 32 consists of two individual legs, each of which is provided with a fold 36 which surrounds the associated holding surface 16 of the attachment lug 12.
- All illustrated embodiments have in common that in the area of at least one clamping surface elevations and groove-shaped depressions are provided, which make the attachment approach of the thermal insulation profile "softer" and thereby bring several advantages.

Description
Die Erfindung betrifft ein Wärmedämmprofil aus Kunststoff zur Befestigung zwischen zwei in einer ersten Richtung voneinander beanstandeten Metallprofilen. Weiterhin betrifft die Erfindung ein Verbundprofil für Fassaden, Fenster und Türen mit einem erfindungsgemäßen Wärmedämmprofil.The invention relates to a thermal insulation profile made of plastic for attachment between two spaced apart in a first direction of metal profiles. Furthermore, the invention relates to a composite profile for facades, windows and doors with a thermal insulation profile according to the invention.
Auch als Isolierstege bezeichnete Wärmedämmprofile werden für die Ausbildung von Rahmen von Fenstern, Türen und Fassaden verwendet. Im Hinblick auf eine möglichst geringe Wärmeleitung zwischen den thermisch entkoppelten Metallprofilen eines Rahmens, werden zwischen die Metallprofile des Rahmens Wärmedämmprofile eingesetzt, die in einer Richtung senkrecht zu ihrer Längserstreckung in den Metallprofilen verankert sind.Also called Isolierstege thermal insulation profiles are used for the formation of frames of windows, doors and facades. With regard to the lowest possible heat conduction between the thermally decoupled metal profiles of a frame, heat-insulating profiles are used between the metal profiles of the frame, which are anchored in a direction perpendicular to their longitudinal extent in the metal profiles.
Die aus einem Kunststoff mit geringer Wärmeleitfähigkeit gefertigten Wärmedämmprofile werden bei der Herstellung von Verbundprofilen mit den Metallprofilen verbunden, indem Befestigungsstege der Metallprofile in Richtung auf die Wärmedämmprofile angerollt werden, um als sogenannte Klemmfäuste die Wärmedämmprofile klemmend zu halten. Um die Wärmedämmprofile sicher halten zu können, sind die Befestigungsstege der Metallprofile häufig mit einer Rändelung versehen.The made of a plastic with low thermal conductivity heat insulation profiles are connected in the production of composite profiles with the metal profiles by fastening webs of the metal profiles are rolled toward the thermal insulation profiles to hold as so-called clamping fists the thermal insulation profiles by clamping. In order to hold the heat-insulating profiles safely, the fastening webs of the metal profiles are often provided with a knurling.
Dabei kommt es zur Vermeidung von Ausschuss bei der Herstellung von Verbundprofilen vor allem darauf an, Toleranzen zwischen den Metallprofilen und den Wärmedämmprofilen gering zu halten und eine ausreichende Schubfestigkeit zwischen den Wärmedämmprofilen und den Metallprofilen sicherzustellen.It is important to avoid rejects in the production of composite profiles, especially on tolerances between the metal profiles and the To keep thermal insulation profiles low and to ensure sufficient shear resistance between the thermal insulation profiles and the metal profiles.
Diese Erfordernisse wirken sich auch auf die Auswahl möglicher Kunststoffmaterialien für die Wärmedämmprofile aus. Um den erforderlichen Toleranzausgleich zwischen dem Wärmedämmprofil und Metallprofil zu ermöglichen, wird im Stand der Technik ein relativ weiches Kunststoffmaterial für die Herstellung des Wärmedämmprofils gewählt. Dadurch ist die Palette möglicher Werkstoffe deutlich eingeschränkt. Darüber hinaus wirken sich bereits geringe Fertigungstoleranzen beim Anrollen der Befestigungsstege der Metallprofile dahingehend aus, dass keine ausreichende Schubfestigkeit hergestellt werden kann.These requirements also affect the choice of possible plastic materials for the thermal insulation profiles. In order to allow the required tolerance compensation between the thermal insulation profile and metal profile, a relatively soft plastic material for the production of the thermal insulation profile is selected in the prior art. This significantly limits the range of possible materials. In addition, even small manufacturing tolerances affect the rolling of the mounting webs of the metal profiles to the effect that no sufficient shear strength can be produced.
der Erfindung liegt die Aufgabe zu Grunde, ein Wärmedämmprofil sowie ein Verbundprofil mit einem derartigen Wärmedämmprofil zu schaffen, die trotz einer erweiterten Werkstoffpalette eine verbesserte Schubfestigkeit der Verbindung zwischen Wärmedämmprofil und Metallprofil ermöglichen.The invention is based on the object to provide a thermal insulation profile and a composite profile with such a thermal insulation profile, which allow an improved shear strength of the connection between the thermal insulation profile and metal profile despite an expanded range of materials.
Diese Aufgabe wird durch ein Wärmedämmprofil mit den Merkmalen des Anspruchs 1 sowie ein Verbundprofil für Fassaden, Fenster und Türen mit den Merkmalen des Anspruchs 12 gelöst. Vorteilhafte Ausführungsformen folgen aus den übrigen Ansprüchen.This object is achieved by a thermal insulation profile with the features of claim 1 and a composite profile for facades, windows and doors with the features of
Das erfindungsgemäße Wärmedämmprofil aus Kunststoff zur Befestigung zwischen zwei in einer ersten Richtung voneinander beanstandeten Metallprofilen umfasst einen Mittelsteg sowie an beiden Enden des Mittelstegs mindestens einen Befestigungsansatz. Jeder Befestigungsansatz ist gestaltet und dimensioniert, um formschlüssig sowie klemmend in einer Klemmfaust des zugehörigen Metallprofils aufgenommen zu werden. Das Wärmedämmprofil ist dadurch gekennzeichnet, dass jeder Befestigungsansatz mit einer Vielzahl von Erhebungen und zwischen den Erhebungen vorgesehenen rillenförmigen Vertiefungen versehen ist, wobei die Erhebungen und rillenförmigen Vertiefungen in einer Richtung senkrecht zur ersten Richtung verlaufen und an jedem Befestigungsansatz an mindestens einer Klemmfläche vorgesehen sind, die im Wesentlichen parallel zur ersten Richtung verläuft.The inventive plastic thermal insulation profile for attachment between two spaced apart in a first direction metal profiles comprises a central web and at both ends of the central web at least one attachment lug. Each attachment lug is designed and dimensioned to form-fitting and clamping to be received in a clamping fist of the associated metal profile. The heat-insulating profile is characterized in that each attachment lug is provided with a plurality of elevations and groove-shaped recesses provided between the elevations, wherein the elevations and groove-shaped depressions extend in a direction perpendicular to the first direction and are provided on each attachment lug on at least one clamping surface is substantially parallel to the first direction.
Durch das Vorsehen der Erhebungen und Vertiefungen in einer Richtung senkrecht zur ersten Richtung lassen sich mehrere Vorteile gleichzeitig erzielen. Das Vorsehen der Rillen gibt dem Kunststoffmaterial des Wärmedämmprofils eine erhöhte Nachgiebigkeit. Mit anderen Worten wirkt das Wärmedämmprofile in diesem Bereich weicher als es seinen tatsächlichen Materialeigenschaften entspricht. Daher können auch Kunststoffmaterialien zur Herstellung des Wärmedämmprofils ausgewählt werden, die aufgrund ihrer hohen Druckfestigkeit bislang nicht zur Herstellung von Wärmedämmprofilen in Verbundprofilen zum Einsatz kamen. Auf diese Weise lassen sich Werkstoffe einsetzen, die eine höhere Festigkeit und, damit verbunden, auch eine höhere Härte aufweisen.By providing the elevations and depressions in a direction perpendicular to the first direction, several advantages can be achieved simultaneously. The provision of the grooves gives the plastic material of the thermal insulation profile increased flexibility. In other words, the thermal insulation profiles in this area softer than it corresponds to its actual material properties. Therefore, plastic materials can be selected for the production of the thermal insulation profile, which have not yet been used for the production of thermal insulation profiles in composite profiles due to their high compressive strength. In this way, materials can be used which have a higher strength and, associated therewith, also a higher hardness.
Ein weiterer Vorteil des erfindungsgemäßen Wärmedämmprofils besteht darin, dass durch das Vorsehen der Erhebungen und Rillen ein vereinfachter Toleranzausgleich zwischen dem Wärmedämmprofil und den zugehörigen Metallprofilen möglich wird.Another advantage of the thermal insulation profile according to the invention is that by providing the elevations and grooves a simplified tolerance compensation between the heat-insulating profile and the associated metal profiles is possible.
Schließlich besitzt das erfindungsgemäße Wärmedämmprofil den Vorteil, dass das Kunststoffmaterial der Erhebungen leichter in die Vertiefungen einer Rändelung eindringen kann, die in denjenigen Bereichen der Klemmfäuste der Metallprofile vorgesehen sein kann, die mit den Klemmflächen des Wärmedämmprofils in Kontakt treten.Finally, the heat-insulating profile according to the invention has the advantage that the plastic material of the elevations can easily penetrate into the recesses of a knurling, which can be provided in those areas of the clamping fists of the metal profiles, which come into contact with the clamping surfaces of the heat-insulating profile.
Nach einer bevorzugten Ausführungsform der Erfindung weist mindestens ein Befestigungsansatz des Wärmedämmprofils eine Keilform auf, wobei sich die Keilform in der ersten Richtung zum Ende des Wärmedämmprofils hin verjüngt. Mit anderen Worten sind die Klemmflächen winklig zueinander angeordnet, wodurch sich die Zentrierung des Wärmedämmprofils in den Klemmfäusten der Metallprofile bei der Herstellung eines Verbundprofils erleichtern lässt.According to a preferred embodiment of the invention, at least one attachment lug of the thermal insulation profile has a wedge shape, wherein the wedge shape tapers in the first direction toward the end of the thermal insulation profile. In other words, the clamping surfaces are arranged at an angle to each other, which can facilitate the centering of the thermal insulation profile in the clamping fists of the metal profiles in the production of a composite profile.
Nach einer alternativen bevorzugten Ausführungsform der Erfindung weist mindestens ein Befestigungsansatz des Wärmedämmprofils eine Keilform auf, wobei sich die Keilform in der ersten Richtung zum Ende des Wärmedämmprofils hin verbreitert. Auch bei dieser Gestaltungsvariante sind die Klemmflächen winklig zueinander angeordnet, doch bildet sich zusätzlich eine Formschlussverbindung zwischen den Befestigungsansätzen des Wärmedämmprofils und den Metallprofilen.According to an alternative preferred embodiment of the invention, at least one attachment lug of the thermal insulation profile has a wedge shape, widening the wedge shape in the first direction towards the end of the heat-insulating profile. Also in this design variant, the clamping surfaces are arranged at an angle to each other, but in addition forms a positive connection between the mounting lugs of the thermal insulation profile and the metal profiles.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung weist mindestens ein Befestigungsansatz des Wärmedämmprofils eine Klemmfläche auf, die gekrümmt ist und den Befestigungsansatz in einer zweiten Richtung senkrecht zur ersten Richtung verbreitert. Auch nach dieser bevorzugten Ausführungsform der Erfindung bildet sich zusätzlich eine Formschlussverbindung zwischen den Befestigungsansätzen des Wärmedämmprofile und den Metallprofilen, weil die Klemmfäuste der Metallprofile die ballig geformten Klemmflächen der Befestigungsansätze umgreifen.According to a further preferred embodiment of the invention, at least one attachment lug of the thermal insulation profile has a clamping surface which is curved and widens the attachment lug in a second direction perpendicular to the first direction. Also according to this preferred embodiment of the invention, in addition, a positive connection between the mounting lugs of the thermal insulation profiles and the metal profiles, because the Klemmfäuste the metal profiles surround the spherically shaped clamping surfaces of the attachment lugs.
Die alternativ möglichen Geometrie für die Befestigungsansätze mit keilförmigen oder balligen Befestigungsansätzen richten sich nach den gewünschten Umformtechniken und -bedingungen. Auch im Fall von keilförmigen oder balligen Befestigungsansätzen verlaufen die Klemmflächen im Wesentlichen in der ersten Richtung. Vorzugsweise umfasst der mindestens eine Befestigungsansatz weiterhin eine Zentrierfläche, welche senkrecht zur ersten Richtung orientiert ist und das Ende des Wärmedämmprofils in der ersten Richtung darstellt, wobei die Zentrierfläche eine konvexe Ausformung oder konkave Einformung umfasst.The alternative possible geometry for the attachment approaches with wedge-shaped or crowned attachment approaches depend on the desired forming techniques and conditions. Also in the case of wedge-shaped or crowned fastening lugs, the clamping surfaces extend substantially in the first direction. Preferably, the at least one attachment lug further comprises a centering surface which is oriented perpendicular to the first direction and represents the end of the heat-insulating profile in the first direction, wherein the centering surface comprises a convex or concave indentation.
Durch das Vorsehen einer Zentrierfläche erfolgt während der Herstellung des Verbundprofils eine automatische Vorjustierung des Wärmedämmprofils vor dem Anwalzen des Metallprofils. Es findet somit eine Ausrichtung des Wärmedämmprofils im umgreifenden Metallteil statt.By providing a centering occurs during the production of the composite profile an automatic pre-adjustment of the thermal insulation profile before rolling the metal profile. It thus takes place an alignment of the thermal insulation profile in the encompassing metal part.
Je nach der Gestaltung der Zentrierfläche kann dabei das gewünschte Ausmaß an Selbstzentrierung vorgewählt werden. So kann nach einer bevorzugten Ausführungsvariante die Zentrierfläche gekrümmt sein, während nach einer alternativen, bevorzugten Ausführungsvariante die Zentrierfläche zwei winklig zueinander angeordnete Zentrierflächenabschnitte umfasst. Dabei ermöglicht die gekrümmte Geometrie der Zentrierfläche eine wirkungsvollere Zentrierung, da sich der Befestigungsansatz beim Anrollen die richtige Lage "sucht".Depending on the design of the centering while the desired amount of self-centering can be selected. Thus, according to a preferred embodiment, the centering surface may be curved, while according to an alternative preferred embodiment, the centering surface comprises two centering surface sections arranged at an angle to one another. In this case, the curved geometry of the centering allows a more effective centering, since the mounting lug "searches" the right position when rolling.
Nach einer bevorzugten Ausführungsform der Erfindung ist zwischen dem Befestigungsansatz und dem Mittelsteg des Wärmedämmprofils mindestens eine im Wesentlichen senkrecht zur ersten Richtung verlaufende Haltefläche vorgesehen.According to a preferred embodiment of the invention, at least one retaining surface extending substantially perpendicularly to the first direction is provided between the fastening projection and the central web of the thermal insulation profile.
Das Vorsehen mindestens einer Haltefläche bietet den Vorteil, dass die den Befestigungsansatz umgebende Klemmfaust des zugehörigen Metallprofils den Befestigungsansatz formschlüssig umgreift und daher eine erhöhte Festigkeit des Verbundprofils in der ersten Richtung ermöglicht.The provision of at least one retaining surface offers the advantage that the clamping lug of the associated metal profile surrounding the fastening lug embraces the fastening lug in a form-fitting manner and therefore enables increased strength of the composite profile in the first direction.
Nach einer bevorzugten Ausführungsform der Erfindung besitzen die Erhebungen mindestens einer Klemmfläche eine im Wesentlichen spitze Querschnittsform. Je nach der Wahl des Materials für das Wärmedämmprofil kann die Querschnittsform der Erhebungen gestaltet werden. Je spitzer die Erhebungen zulaufen, desto härter kann das Material des Wärmedämmprofils ausgewählt werden. Wird ein Material mit geringerer Härte eingesetzt, so können die Erhebungen nach einer alternativen, bevorzugten Ausführungsform der Erfindung eine im Wesentlichen ballige Form besitzen.According to a preferred embodiment of the invention, the elevations have at least one clamping surface in the Essentially sharp cross-sectional shape. Depending on the choice of material for the thermal insulation profile, the cross-sectional shape of the surveys can be designed. The sharper the elevations run, the harder the material of the thermal insulation profile can be selected. If a material with a lower hardness is used, then the elevations according to an alternative, preferred embodiment of the invention may have a substantially spherical shape.
Vorzugsweise nimmt die relative Höhe der Erhebungen über dem Nutgrund der rillenförmigen Vertiefungen in der ersten Richtung und mit zunehmendem Abstand zum Ende des Befestigungsansatzes zu. Auf diese Weise befindet sich mehr Material an derjenigen Position im Übergangsbereich zum Mittelsteg, an der beim Umformen des Metallprofils die größte Kraft auf den Befestigungsansatz wirkt.Preferably, the relative height of the protrusions above the groove bottom of the groove-shaped recesses increases in the first direction and with increasing distance to the end of the attachment lug. In this way, there is more material at that position in the transition region to the central web on which acts when forming the metal profile, the largest force on the attachment approach.
Nach einer bevorzugten Ausführungsform ist mindestens eine der rillenförmigen Vertiefungen als Zentriernut ausgestaltet und dabei so angeordnet und dimensioniert, um eine Zentriernase an der Klemmfaust des Metallprofils aufzunehmen. Durch das Vorsehen einer Zentriernase am Metallprofil kann eine zusätzliche formschlüssige Verbindung zwischen dem Metallprofil und dem Befestigungsansatz hergestellt werden und darüber hinaus die Auszugsfestigkeit des Wärmedämmprofils weiter erhöht werden.According to a preferred embodiment, at least one of the groove-shaped depressions is configured as a centering groove and in this case arranged and dimensioned in order to receive a centering nose on the clamping fist of the metal profile. By providing a centering nose on the metal profile, an additional positive connection between the metal profile and the attachment approach can be made and beyond the pull-out strength of the thermal insulation profile can be further increased.
Das erfindungsgemäße Verbundprofil ist vorzugsweise so gestaltet und auf die Geometrie des Wärmedämmprofils abgestimmt, dass der lichte Abstand in der den Befestigungsansatz klemmend umgreifenden Klemmfaust geringer ist als die entsprechende Normabmessung des Befestigungsansatzes.The composite profile according to the invention is preferably designed and tuned to the geometry of the thermal insulation profile, that the clear distance in the clamping lug clampingly embracing the fastening lug is less than the corresponding standard dimension of the attachment lug.
Durch diese Maßnahme wird erreicht, dass der gegenüber der Geometrie der Klemmfaust mit Übermaß gefertigte Befestigungsansatz des Wärmedämmprofils beim Anrollen der Klemmfaust um den Befestigungsansatz elastisch verformt wird.By this measure it is achieved that the manufactured over the geometry of the clamping fist with excess Fixing approach of the thermal insulation profile is elastically deformed when rolling the clamping fist around the mounting lug.
Vorzugsweise ist eine Rändelung an denjenigen Teilen der Klemmfäuste der Metallprofile vorgesehen, die die mindestens eine Klemmfläche des Befestigungsansatzes kontaktiert. Durch das Vorsehen einer Rändelung werden die Auszugsfestigkeit sowie Schubfestigkeit weiter erhöht.Preferably, a knurling is provided on those parts of the clamping fists of the metal profiles, which contacts the at least one clamping surface of the fastening lug. By providing a knurl the pull-out strength and shear resistance are further increased.
Nachfolgend wird die Erfindung rein beispielhaft anhand der beiliegenden Figuren beschrieben, in denen jeweils die Querschnittsform eines Teils eines Wärmedämmprofils dargestellt ist. Es wird dabei jeweils nur der Bereich nahe einem Ende eines Wärmedämmprofils dargestellt, d.h. der Befestigungsansatz für eine der beiden Metallschalen sowie einen Teil des sich daran anschließenden Mittelstegs.The invention will be described purely by way of example with reference to the accompanying figures, in which in each case the cross-sectional shape of a part of a thermal insulation profile is shown. In each case only the area near one end of a thermal insulation profile is shown, i. the attachment approach for one of the two metal shells and a part of the adjoining center bar.

Das Wärmedämmprofil besteht im Wesentlichen aus Kunststoff, jedoch können je nach dem gewünschten Anwendungsfall auch ergänzend weitere Werkstoffe zum Einsatz kommen. So ist es möglich, glasfaserverstärkten Kunststoff einzusetzen. Soll das Wärmedämmprofil in einem Verbundprofil eingesetzt werden, das Brandschutzerfordernisse erfüllen muss, so kann beispielsweise auch im Inneren des Kunststoffmaterials ein Metallprofil eingebettet sein, das im Brandfall, wenn der Kunststoff des Wärmedämmprofils abschmilzt, zumindest noch über einen vorbestimmten Zeitraum die Metallprofile miteinander verbindet. In gleicher Weise ist es auch möglich, an dem Mittelsteg des Wärmedämmprofils weitere Elemente zu befestigen, z.B. Elemente, die aus energieverzehrenden Materialien bestehen oder aber unter Hitzeeinwirkung aufschäumen.The heat-insulating profile consists essentially of plastic, but depending on the desired application, additional materials can also be used in addition. So it is possible to use glass fiber reinforced plastic. If the thermal insulation profile is to be used in a composite profile which has to meet fire protection requirements, it is also possible, for example, for a metal profile to be embedded in the interior of the plastic material, which in the event of fire, if the plastic of the thermal insulation profile melts, connects the metal profiles to each other at least for a predetermined period of time. In the same way, it is also possible to attach further elements to the central web of the thermal insulation profile, e.g. Elements that consist of energy-consuming materials or that foam up under the influence of heat.

Im Bereich des Befestigungsansatzes 12 sind zwei Klemmflächen 18 vorgesehen, die bei der Herstellung eines Verbundprofils in die Klemmfäuste des Metallprofils eingeklemmt werden.In the region of the
Die Klemmflächen 18 sind dabei mit einer Vielzahl von Erhebungen 20 sowie rillenförmigen Vertiefungen 22 versehen. Die Erhebungen 20 sowie rillenförmigen Vertiefungen 22 verlaufen dabei in Längsrichtung der Wärmedämmprofile und lassen sich daher beim Extrudieren der Wärmedämmprofile leicht herstellen. Die Erhebungen 20 lassen sich bei der Herstellung des Verbundprofils und insbesondere wenn im Rahmen eines Umformprozesses die Klemmfäuste um die Befestigungsansätze 12 gerollt werden, verformen. Durch die leichtere Verformbarkeit der Erhebungen 20 lassen sich zahlreiche Vorteile erzielen. Zum einen wird die Elastizität des Befestigungsansatzes erhöht, wodurch sich der Toleranzausgleich zwischen dem Wärmedämmprofil und dem zugehörigen Metallprofil verbessern lässt. Darüber hinaus kann die Schubfestigkeit der Verbindung zwischen dem Wärmedämmprofil und dem zugehörigen Metallprofil verbessert werden, indem das Kunststoffmaterial des Wärmedämmprofils leichter in Vertiefungen an den Kontaktflächen der Metallprofile eindringen kann, die entweder durch eine Rändelung erzeugt wird oder aber durch Aufrauen mittels Strahlen der Metallprofile.The clamping surfaces 18 are provided with a plurality of
Indem durch das Vorsehen der Rillen der Befestigungsansatz elastischer wird, können zur Herstellung des Wärmedämmprofils Werkstoffe mit höherer Festigkeit eingesetzt werden, die häufig auch eine höhere Härte aufweisen. Auf diese Weise kann durch das Vorsehen der Rillen die Werkstoffpalette erweitert werden. Ein weiterer Effekt, der allerdings nicht im Vordergrund steht, ist eine leicht verbesserte Wärmedämmung, da aufgrund der rillenförmigen Vertiefungen die Kontaktfläche zwischen dem Befestigungsansatz und der zugehörigen Klemmfaust des Metallprofils im Vergleich zu einer vollflächigen Anlage leicht verringert ist.By making the mounting lug more elastic by providing the grooves, materials of higher strength, which often also have a higher hardness, can be used to produce the heat-insulating profile. In this way, by providing the grooves, the range of materials can be extended. Another effect, which is not in the foreground, is a slightly improved thermal insulation, as due to the groove-shaped depressions, the contact surface between the attachment lug and the associated clamping fist of the metal profile is slightly reduced compared to a full-surface investment.

Die Wahl der Geometrie der Erhebungen und zugehörigen rillenförmigen Vertiefungen richtet sich nach den Materialeigenschaften des Wärmedämmprofils. Je härter das verwendete Kunststoffmaterial des Wärmedämmprofils ist oder je größer die gewünschte Materialverformung sein soll, desto spitzer zulaufend können die Erhebungen 20 ausgestaltet werden, bis zu der relativ scharfkantigen Sägezahnform, die schematisch anhand der Erhebungen 20a dargestellt ist. Ist das Kunststoffmaterial jedoch von geringerer Härte, dann bietet sich die Geometrie mit wellenförmigen Erhebungen 20b an.The choice of the geometry of the elevations and associated groove-shaped depressions depends on the material properties of the thermal insulation profile. The harder the plastic material used of the thermal insulation profile or the greater the desired material deformation should be, the more pointed the

Allen dargestellten Ausführungsformen ist gemeinsam, dass im Bereich mindestens einer Klemmfläche Erhebungen und rillenförmige Vertiefungen vorgesehen sind, die den Befestigungsansatz des Wärmedämmprofils "weicher" machen und dadurch mehrere Vorteile mit sich bringen. Es wird der Toleranzausgleich zwischen dem Wärmedämmprofil und dem zugehörigen Metallprofil verbessert, die Schubfestigkeit der Verbindung verbessert, indem das Material in einer an den Kontaktflächen der Metallprofile vorhandene Rändelung eindringen kann und es ist möglich, die Wärmedämmprofile aus Werkstoffen mit höherer Festigkeit zu fertigen.All illustrated embodiments have in common that in the area of at least one clamping surface elevations and groove-shaped depressions are provided, which make the attachment approach of the thermal insulation profile "softer" and thereby bring several advantages. It improves the tolerance compensation between the thermal insulation profile and the associated metal profile, the shear strength of the compound improves by the material can penetrate into a present at the contact surfaces of the metal profiles knurling and it is possible to manufacture the thermal insulation profiles of materials with higher strength.
