Definitions

  • the present invention relates to a composite profile for doors, windows or facade elements according to the preamble of claim 1.
  • the temperature-related deformation of the composite profiles has a negative effect on the function of the seals and locking systems.
  • the at least one insulating web or the several insulating webs that are part of the thrustless connection overall over its entire length together with both end sections but also in his / her web section between the grooves of the metal profiles has / have a C-shaped cross-sectional geometry.
  • the invention according to claim 23 also creates a window or a door or a facade element with at least one or more composite profiles according to one of the claims related thereto.
  • the invention is thus based on the idea of resiliently pre-tensioning the insulating webs, which are provided for a thrustless connection, by means of a suitable geometry of the insulating web (s) along with a forming process for connecting the insulating webs to a metallic partial profile.
  • a resilient, pre-tensioned insulating bar in the assembled state is made available, which advantageously the relatively large manufacturing tolerances in the assembled state can compensate in particular of coated metallic partial profiles.
  • the opposing insulating webs are arranged with their open side in the same direction, so that the amount of the resilient preload is advantageously added for two insulating webs.
  • a C-shaped recess of the insulating web is provided with undercuts in its web section between the grooves of the metal profiles in order to be able to easily attach folding elements, such as seals, in an advantageous manner.
  • Fig. 1 an inventive composite profile 1 is shown.
  • This composite profile 1 can be used as a sash profile as part of a sash or window frame for doors, windows or other facade elements, so that the following description applies equally to sash profiles and window frame profiles.
  • the composite profile 1 has a first metal profile, a metallic outer profile 2, in which at least one hollow chamber 3 is formed, and a second metallic outer profile 4, in which at least one hollow chamber 5 is also formed. Between the two metal profiles 2 and 4, a third metal profile, a metallic middle profile 6, is provided, in which at least one hollow chamber 7 is also formed.
  • the metallic profiles 2, 4, 6 can alternatively also be designed without pronounced hollow chambers 3, 5, 7 or have several hollow chambers.
  • the first metallic outer profile 2 is connected to the metallic middle profile 6 via at least one or more first insulating webs (here parallel) 8. These insulating webs 8 between the first metallic outer profile 2 and the metallic middle profile 6 form a first insulating web zone I or plane.
  • the second metallic outer profile 4 is also connected to the metallic middle profile 6 via at least one or more second (here parallel) insulating webs 9. The insulating webs 9 between the second metallic outer profile 4 and the metallic central profile 6 form a second insulating web zone II or plane.
  • the first and second insulating webs 8, 9 here - purely by way of example - have no hollow chambers.
  • the insulating webs 8, 9 can also have one or more hollow chambers or the first or second insulating webs in each case can be combined by cross webs to form a type of superordinate insulating profile.
  • the insulating webs 8, 9 of the insulating web zones I, II are here - purely by way of example - in one plane. Alternatively, it is also possible that the insulating webs 8, 9 of the insulating web zones I, II are each arranged vertically and / or horizontally offset from one another.
  • the first and second metallic outer profile 2 and 4 and the metallic middle profile 6 are preferably produced as extruded aluminum profiles. Alternatively, it can also be manufactured from a different material such as steel and / or a different manufacturing process.
  • the insulating webs 8 and 9 are made of a material that reduces heat transfer, preferably a plastic material produced so that an extensive thermal separation between the metal profiles 2, 4, 6 is achieved.
  • metallic insulating bars with reduced heat transmission can also be used, which can be provided with interruptions or recesses to reduce the heat transmission (such as in EP 0 717 165 A2 disclosed).
  • the insulating webs 8 and 9 are preferably web-shaped in cross section and have thickened end sections 10.
  • each of the end sections 10 preferably engages in a corresponding groove 11 of one of the metal profiles 2, 4, 6, with the groove walls the thickened end sections 10 of the insulating webs 8, 9 in the x and y directions (see coordinate system in Fig. 1 ) preferably grip around positively.
  • the respective end section 10 preferably has a trapezoidal or triangular or wedge-shaped or L-shaped or rectangular cross section.
  • the respective groove 11 accordingly has a cross section with a respective corresponding cross section.
  • Fig. 1 has - for example - the second insulating web zone II on the second insulating webs 9, the respective end sections 10 of which are positively and non-positively connected to the respective groove 11, so that each one, in particular, also in the z-direction (see coordinate system in Fig. 1 ) or in a direction orthogonal to the cross-sectional plane of the composite profile 1 results in a shear-proof connection between the second insulating webs 9 and the outer and middle metal profiles adjacent to them.
  • This connection is hereinafter also referred to as a shear-resistant design of one of the two - here the second - insulating web zones. It offers a shear strength against the forces occurring as a result of dilation on a window or a door or the like.
  • the shear strength of the other - here the first - insulating web zone I is lower in all variants than that of the first insulating web zone II. It is selected so that at least two elements in the insulating web zone can be moved relative to one another due to dilation.
  • the insulating web zone I of lower shear strength is preferably located on a window or door on the outside of the building when installed, since the temperature differences are greater here than on the inside of the building, so that the lower shear strength is particularly important here to compensate for dilatation effects.
  • the insulating web zone with increased shear strength is preferably located on the inside of the room. This variant of the invention is particularly advantageous. However, it is also conceivable to provide the insulating web zone with higher shear strength on the outside of the room.
  • the first insulating web zone I preferably has - see Fig. 1 - Insulating webs 8, which each have a first end section 10 at one of their two ends, which is positively and non-positively connected to the respective groove 11, so that in each case one in particular also extends in the z-direction (see coordinate system in Fig. 1 ) results in a shear-proof connection.
  • the second ends of the first insulating webs 8 of the first insulating web zone I have an end section 12 which has a substantially welt-like cross section.
  • the welt-like cross section is formed by a welt bead 13 and a welt flap 14.
  • the welt bead 13 here has - purely by way of example - a circular cross section.
  • the welt bead 13 can alternatively also have a non-circular or oval or polygonal cross section.
  • the respective welt bead 13 engages in a groove 15 - here also purely by way of example - of the first metallic outer profile 2, while the welt flap 14 is guided out of a groove opening out of the groove 15, the groove walls of the respective end sections 12 having a substantially welt-like cross section of the insulating bars 8 in the x and y directions (see coordinate system in Fig. 1 ) grip positively.
  • the end section 12 with an essentially welt-like cross-section is - in contrast to the end section 10 - but not connected to the groove 15 in a shear-proof manner, so that one in the z-direction (see coordinate system in Fig. 1 ) a shear-reduced connection - also referred to synonymously in the prior art as a shear-soft or shearless connection - is created, which can advantageously absorb temperature-related deformations of the first metallic outer profile 2.
  • Fig. 5 6th and 7th expressions according to the invention of a shear-soft or shearless connection in the end section 12 of an insulating web 8 are shown.
  • a composite profile 1 according to the invention can also have a shear-reduced, i.e. have a shear-soft or shearless connection between the second metallic outer profile 4 and the insulating webs 9 or the metallic middle profile, while the first insulating web zone I has a relatively shear-resistant connection between the first metallic outer profile 2 and the insulating webs 8 or the metallic one Has central profile 6.
  • the composite profile 1 can also be used in both insulating web zones I, II in relation to the z-direction (cf. coordinate system in FIG Fig. 1 ) a flexible or non-flexible connection of the metallic outer profiles 2, 4 and the respective insulating webs 8, 9 or with the metallic middle profile 6.
  • the first metallic outer profile 2 is separated from the metallic central profile 6 preferably via a hollow chamber 16 which is formed in the first insulating web zone I between the two first insulating webs 8 and the adjacent metal profiles, while the metallic central profile 6 is separated from the second metallic outer profile 4 via a Hollow chamber 17 is separated, which is located in the second insulating web zone II between the second insulating webs 9 and the adjacent metal profiles.
  • a plurality of hollow chambers 3, 16, 7, 17 and 5 are formed from an outer side of the first metallic outer profile 2 to a second outer side of the second metallic outer profile 4, which provide good thermal insulation.
  • the metallic outer profiles 2 and 4 have outwardly protruding webs 18 and 19 on opposite sides, with a groove 20 for receiving a seal on the end of the web 18 and a further groove 21 for receiving a seal on the web 19.
  • the webs 18 and 19 can also be present on one side, only one of these webs or none of these webs.
  • Fig. 2 or in Figures 3 and 4 is a further variant of a composite profile according to Fig. 1 shown.
  • a variant of the Keder bead 13 or 23 is shown.
  • the welt bead 13 or 23 has a circular cross-sectional geometry.
  • the cross-sectional geometry of the welt bead 13 or 23 can also be oval, elliptical or polygonal.
  • the welt bead 13 or 23 can have a co-extruded film or layer on its surface.

  • the co-extruded film accordingly creates a layer that is firmly connected to the respective insulating web 8, 22 and has a particularly low coefficient of friction in the area of the welt bead 13 or 23, so that in the z-direction (see coordinate system in Fig. 1 or. Fig. 2 ) a quasi-thrust-free or thrust-soft connection is created.
  • a groove 15 or 25 is shown on a metal profile or an insulating web section.
  • the groove 15 or 25 has a circular cross-sectional geometry.
  • the cross-sectional geometry of the groove 15 or 25 can also be oval, elliptical or polygonal; this depends on the selected cross-sectional geometry of the welt bead 13 or 23, with which the cross-sectional geometry of the groove 15 or 25 corresponds.
  • the groove 15 or 25 can have a splined hub-like cross-sectional geometry 31 or a splined hub-like cross-sectional geometry.
  • Figure 13 and 14th show the prior art schematically before and after the webs formed on the metal profiles 2, 4, 6 are rolled onto the insulating web 8.
  • Figure 13 shows the prior art of EP 0 829 609 A2 according to the Figure 4 , but before assembly.
  • the non-thrust bond area is shown with a particularly large tolerance range (gap).
  • the tolerances, or the gap are compensated for after the six-meter-long profiles have been installed by rolling the web.
  • a force F is applied to the web of the respective metal profile 2, 4, 6 in order to achieve a plastic deformation of the web until the web comes into contact with the insulating web 8 and so in the case of a shear-resistant connection between the insulating web 8 or between the end piece 10 of the insulating web 8 and the groove 11 a positive and non-positive connection with respect to a deformation direction in the profile plane or in the z-direction with respect to the coordinate system in Fig. 1 or. Fig. 2 is created.
  • FIG. 14 illustrates tilting of the insulating web 8 due to the rolling due to the large tolerances required and the resulting large play, whereby the composite profile according to the prior art is not suitable overall for door or window constructions.
  • the tilting blocks the shear mobility, the large play limits the dimensional accuracy of the composite profile and reduces the static load-bearing capacity of the composite profile.
  • Figure 5 shows a first insulating web 8a according to the invention with a C-shaped cross-sectional geometry.
  • the insulating web 8a is characterized by a thrustless area A and a shear-resistant area B.

Description

Die vorliegende Erfindung betrifft ein Verbundprofil für Türen, Fenster oder Fassadenelemente nach dem Oberbegriff des Anspruchs 1.The present invention relates to a composite profile for doors, windows or facade elements according to the preamble of claim 1.

Bei Verbundprofilen für Türen, Fenster oder Fassadenelementen mit Isolierstegen kommt es bei einseitiger Temperaturerhöhung oder -verminderung, wie sie im jahreszeitlichen Wechsel vorkommen, zu Schubspannungen zwischen den Bauteilen der Verbundprofile. Aufgrund der Schubfestigkeit des Verbundprofilaufbaus kommt es durch die Schubspannungen zu Verformungen des Verbundprofils, aus denen eine Wölbung zur wärmeren Seite des Verbundprofils resultiert. Solche Verformungen können die Funktion des aus dem Verbundprofil aufgebauten Tür- oder Fensterrahmens beeinträchtigen.In the case of composite profiles for doors, windows or facade elements with insulating bars, there is a one-sided temperature increase or decrease, as it occurs in the seasonal change, to shear stresses between the components of the composite profiles. Due to the shear strength of the composite profile structure, the shear stresses cause deformations of the composite profile, which results in a bulge towards the warmer side of the composite profile. Such deformations can impair the function of the door or window frame constructed from the composite profile.

Insbesondere bei relativ langen Verbundprofilen, die als Rahmenholme von Türen eingesetzt werden, wirkt sich die temperaturbedingte Verformung der Verbundprofile negativ auf die Funktion der Dichtungen und Verriegelungssysteme aus.Particularly in the case of relatively long composite profiles that are used as frame rails for doors, the temperature-related deformation of the composite profiles has a negative effect on the function of the seals and locking systems.

Aus dem Stand der Technik sind Lösungen bekannt, die sich mit der Vermeidung bzw. Abmilderung solcher Spannungen bzw. Verformungen von Verbundprofilen befassen. So wird in der EP 0 829 609 A2 vorgeschlagen, dass in einem Isoliersteg mit dem ein Innen- und ein Außenprofil verbunden ist, die Schubfestigkeit gering ist, gegen null geht oder eine Gleitführung vorhanden ist.Solutions are known from the prior art which deal with the avoidance or alleviation of such stresses or deformations of composite profiles. So in the EP 0 829 609 A2 suggested that in an insulating web with which an inner and an outer profile is connected, the shear strength is low, approaches zero or a sliding guide is present.

Verbundprofile nach Art der EP 0 829 609 A2 haben sich an sich bewährt. Die Verbundprofile nach Art der Fig. 4 der EP 0 829 609 A2 wurden aber aufgrund konstruktiver Unzulänglichkeiten nicht in marktrelevantem Maße umgesetzt. An dieser Konstruktion ist problematisch, dass die Toleranzfelder für die Montage der Profile derart gewählt werden müssen, dass die fertigen Verbundprofile den maßlichen, statischen und insbesondere den qualitativen Anforderungen nicht mehr genügen. Aluminiumprofile werden eloxiert oder farbbeschichtet angeboten. Durch den Eloxalprozess wird geringfügig Material vom Basiswerkstoff abgetragen, während beim Farbbeschichten Material auf den Basiswerkstoff aufgetragen wird. Damit die Konstruktion für beide Beschichtungsprozesse gleichermaßen geeignet ist, müssen entsprechend große Toleranzfelder zur Verfügung gestellt und beherrscht werden, um eine einwandfreie Montage der Profilteile zu gewährleisten.Composite profiles according to the type of EP 0 829 609 A2 have proven themselves. The composite profiles according to the type of Fig. 4 the EP 0 829 609 A2 However, due to structural inadequacies, they were not implemented to a market-relevant extent. The problem with this construction is that the tolerance fields for the assembly of the profiles have to be selected in such a way that the finished composite profiles no longer meet the dimensional, static and, in particular, the qualitative requirements. Aluminum profiles are available anodized or color-coated. The anodizing process removes a small amount of material from the base material, while material is applied to the base material during color coating. So that the construction is equally suitable for both coating processes, must appropriately large tolerance fields are made available and controlled in order to ensure proper assembly of the profile parts.

Bei der Montage der Verbundprofile werden zuerst die metallischen Teilprofile und die Isolierstege aus Kunststoff ineinander geschoben. Eine übliche Profillänge im Fertigungsprozess eines Verbundprofils beträgt hierbei 6 m. Diese große Länge erfordert entsprechend große Toleranzen, so dass bei der Montage die Profile leicht ineinander geschoben werden können. Anschließend werden die Verbindungsbereiche mechanisch miteinander verpresst (angerollt). Hierdurch wird ein schubfester Verbund hergestellt. Die schublose Verbindung bleibt jedoch in ihrem ursprünglichen Zustand, bzw. behält ihr ursprüngliches Toleranzfeld bei. Insgesamt konnte jedoch das Verbundprofil nach der technischen Lehre der Fig. 4 in der EP 0 829 609 A2 bisher nicht befriedigend realisiert werden.When assembling the composite profiles, the metallic partial profiles and the plastic insulating bars are pushed into one another first. A usual profile length in the manufacturing process of a composite profile is 6 m. This great length requires correspondingly large tolerances, so that the profiles can easily be pushed into one another during assembly. The connection areas are then mechanically pressed together (rolled). This creates a shear-resistant bond. The thrustless connection, however, remains in its original state or retains its original tolerance zone. Overall, however, the composite profile according to the technical teaching of Fig. 4 in the EP 0 829 609 A2 have not yet been implemented satisfactorily.

Im Gegensatz dazu hat sich der schublose Verbund entsprechend der EP 0 829 609 A2 , Figur 5 als besonders geeignet herausgestellt. Nachteilig hieran ist jedoch, dass die Isolierstege aufgrund der erforderlichen Präzision relativ teuer sind. Darüber hinaus lassen sich aufgrund der Verbindung innerhalb des Isoliersteges keine kurzen Isolierstege realisieren.In contrast to this, the thrustless connection has changed according to the EP 0 829 609 A2 , Figure 5 proved to be particularly suitable. The disadvantage of this, however, is that the insulating bars are relatively expensive due to the precision required. In addition, because of the connection within the insulating web, no short insulating webs can be implemented.

Vor diesem Hintergrund ist es die Aufgabe der vorliegenden Erfindung, die Nachteile des Standes der Technik nach Art er Fig.4 der EP 0 829 609 A2 zu verringern.Against this background, it is the object of the present invention to address the disadvantages of the prior art of the type he Fig. 4 the EP 0 829 609 A2 to reduce.

Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs 1.The invention solves this problem with the subject matter of claim 1.

Danach besteht ein wesentlicher Unterschied zum Stand der Technik darin, dass der wenigstens eine Isoliersteg oder die mehreren Isolierstege, die Teil der schublosen Verbindung sind, insgesamt über seine / ihre ganze Länge nebst beider Endabschnitte aber auch in seinem / ihrem Stegabschnitt zwischen den Nuten der Metallprofile eine C-förmige Querschnittsgeometrie aufweist / aufweisen.According to this, an essential difference to the prior art is that the at least one insulating web or the several insulating webs that are part of the thrustless connection, overall over its entire length together with both end sections but also in his / her web section between the grooves of the metal profiles has / have a C-shaped cross-sectional geometry.

Die Erfindung schafft nach Anspruch 23 zudem ein Fenster oder eine Tür oder ein Fassadenelement mit wenigstens einem oder mehreren Verbundprofilen nach einem der darauf bezogenen Ansprüche.The invention according to claim 23 also creates a window or a door or a facade element with at least one or more composite profiles according to one of the claims related thereto.

Der Erfindung liegt also der Gedanke zu Grunde, die Isolierstege, die für eine schublose Verbindung vorgesehen sind, durch eine geeignete Geometrie der / des Isolierstege(s) einhergehend mit einem Umformprozess zur Verbindung der Isolierstege mit einem metallischen Teilprofil federelastisch definiert vorzuspannen.The invention is thus based on the idea of resiliently pre-tensioning the insulating webs, which are provided for a thrustless connection, by means of a suitable geometry of the insulating web (s) along with a forming process for connecting the insulating webs to a metallic partial profile.

Durch die C-Form des Isoliersteges insgesamt über seine ihre ganze Länge nebst beider Endabschnitte aber auch in seinem Stegabschnitt zwischen den Nuten der Metallprofile wird demnach ein federelastischer, im montierten Zustand definiert vorgespannter Isoliersteg zur Verfügung gestellt, der im montierten Zustand vorteilhaft die relativ großen Fertigungstoleranzen insbesondere von beschichteten metallischen Teilprofilen ausgleichen kann. Dabei werden die sich gegenüberliegenden Isolierstege mit ihrer offenen Seite in gleicher Richtung angeordnet, so dass sich der Betrag der federelastischen Vorspannung in vorteilhafter Weise bei zwei Isolierstegen addiert.Due to the C-shape of the insulating bar over its entire length in addition to both end sections but also in its bar section between the grooves of the metal profiles, a resilient, pre-tensioned insulating bar in the assembled state is made available, which advantageously the relatively large manufacturing tolerances in the assembled state can compensate in particular of coated metallic partial profiles. The opposing insulating webs are arranged with their open side in the same direction, so that the amount of the resilient preload is advantageously added for two insulating webs.

Als bevorzugte Variante wird eine C-förmige Ausnehmung des Isoliersteges in seinem Stegabschnitt zwischen den Nuten der Metallprofile mit Hinterschnitten versehen, um Falzelemente, wie zum Beispiel Dichtungen, in vorteilhafter Weise einfach befestigen zu können.As a preferred variant, a C-shaped recess of the insulating web is provided with undercuts in its web section between the grooves of the metal profiles in order to be able to easily attach folding elements, such as seals, in an advantageous manner.

Weitere vorteilhafte Ausführungen der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention can be found in the subclaims.

In Fig. 1 ist ein erfindungsgemäßes Verbundprofil 1 dargestellt. Dieses Verbundprofil 1 kann als Flügelrahmenprofil als Teil eines Flügelrahmens oder Blendrahmens für Türen, Fenster oder anderen Fassadenelemente eingesetzt werden, so dass sich die nachfolgende Beschreibung gleichermaßen auf Flügelrahmenprofile und Blendrahmenprofile bezieht.In Fig. 1 an inventive composite profile 1 is shown. This composite profile 1 can be used as a sash profile as part of a sash or window frame for doors, windows or other facade elements, so that the following description applies equally to sash profiles and window frame profiles.

Das Verbundprofil 1 weist ein erstes Metallprofil, ein metallisches Außenprofil 2, auf, in welchem wenigstens eine Hohlkammer 3 ausgebildet ist, sowie ein zweites metallisches Außenprofil 4, in dem ebenfalls wenigstens eine Hohlkammer 5 ausgebildet ist. Zwischen den beiden Metallprofilen 2 und 4 ist ein drittes Metallprofil, ein metallisches Mittelprofil 6, vorgesehen, in dem ebenfalls wenigstens eine Hohlkammer 7 ausgebildet ist.The composite profile 1 has a first metal profile, a metallic outer profile 2, in which at least one hollow chamber 3 is formed, and a second metallic outer profile 4, in which at least one hollow chamber 5 is also formed. Between the two metal profiles 2 and 4, a third metal profile, a metallic middle profile 6, is provided, in which at least one hollow chamber 7 is also formed.

Die metallischen Profile 2, 4, 6 können alternativ auch ohne ausgeprägte Hohlkammern 3, 5, 7 ausgeführt sein oder mehrere Hohlkammern aufweisen.The metallic profiles 2, 4, 6 can alternatively also be designed without pronounced hollow chambers 3, 5, 7 or have several hollow chambers.

Das erste metallische Außenprofil 2 ist mit dem metallischen Mittelprofil 6 über wenigstens einen oder mehrere erste Isolierstege (hier parallele) 8 verbunden. Diese Isolierstege 8 zwischen dem ersten metallische Außenprofil 2 und dem metallischen Mittelprofil 6 bilden eine erste Isolierstegzone I bzw. -ebene. Das zweite metallische Außenprofil 4 ist mit dem metallischen Mittelprofil 6 ebenfalls über wenigstens einen oder mehrere zweite (hier parallele) Isolierstege 9 verbunden. Die Isolierstege 9 zwischen dem zweiten metallischen Außenprofil 4 und dem metallischen Mittelprofil 6 bilden eine zweite Isolierstegzone II bzw. -ebene.The first metallic outer profile 2 is connected to the metallic middle profile 6 via at least one or more first insulating webs (here parallel) 8. These insulating webs 8 between the first metallic outer profile 2 and the metallic middle profile 6 form a first insulating web zone I or plane. The second metallic outer profile 4 is also connected to the metallic middle profile 6 via at least one or more second (here parallel) insulating webs 9. The insulating webs 9 between the second metallic outer profile 4 and the metallic central profile 6 form a second insulating web zone II or plane.

Die ersten und zweiten Isolierstege 8, 9 weisen hier -rein beispielhaft- keine Hohlkammer auf. Alternativ können die Isolierstege 8, 9 aber auch eine oder mehrere Hohlkammern aufweisen oder die jeweils ersten oder die jeweils zweiten Isolierstege können durch Querstege zu einer Art übergeordnetem Isolierprofil zusammengefasst sein.The first and second insulating webs 8, 9 here - purely by way of example - have no hollow chambers. Alternatively, however, the insulating webs 8, 9 can also have one or more hollow chambers or the first or second insulating webs in each case can be combined by cross webs to form a type of superordinate insulating profile.

Die Isolierstege 8, 9 der Isolierstegzonen I, II liegen hier -rein beispielhaft- in einer Ebene. Alternativ ist es auch möglich, dass die Isolierstege 8, 9 der Isolierstegzonen I, II jeweils vertikal und oder horizontal zueinander versetzt angeordnet sind.The insulating webs 8, 9 of the insulating web zones I, II are here - purely by way of example - in one plane. Alternatively, it is also possible that the insulating webs 8, 9 of the insulating web zones I, II are each arranged vertically and / or horizontally offset from one another.

Das erste und zweite metallische Außenprofil 2 und 4 sowie das metallische Mittelprofil 6 sind vorzugsweise als stranggepresste Aluminiumprofile hergestellt. Alternativ ist die Herstellung auch aus einem anderen Werkstoff wie Stahl und/oder einem anderen Fertigungsverfahren möglich. Die Isolierstege 8 und 9 sind aus einem, den Wärmedurchgang reduzierendem, Werkstoff, vorzugsweise aus einem Kunststoffwerkstoff hergestellt, so dass jeweils eine weitgehende thermische Trennung zwischen den Metallprofilen 2, 4, 6 erreicht wird.The first and second metallic outer profile 2 and 4 and the metallic middle profile 6 are preferably produced as extruded aluminum profiles. Alternatively, it can also be manufactured from a different material such as steel and / or a different manufacturing process. The insulating webs 8 and 9 are made of a material that reduces heat transfer, preferably a plastic material produced so that an extensive thermal separation between the metal profiles 2, 4, 6 is achieved.

Alternativ können auch metallische Isolierstege mit herabgesetztem Wärmedurchlass eingesetzt werden, die zur Reduzierung des Wärmedurchgangs mit Unterbrechungen bzw. Aussparungen versehen sein können (wie z.B. in EP 0 717 165 A2 offenbart).Alternatively, metallic insulating bars with reduced heat transmission can also be used, which can be provided with interruptions or recesses to reduce the heat transmission (such as in EP 0 717 165 A2 disclosed).

Vorzugsweise sind die Isolierstege 8 und 9 im Querschnitt stegförmig ausgebildet und weisen verdickte Endabschnitte 10 auf. Vorzugsweise greift dabei jeder der Endabschnitte 10 in eine korrespondierende Nut 11 von jeweils einem der Metallprofile 2, 4, 6 ein, wobei die Nutwände die verdickten Endabschnitte 10 der Isolierstege 8, 9 in x- und y-Richtung (siehe Koordinatensystem in Fig. 1) vorzugsweise formschlüssig umgreifen. Der jeweilige Endabschnitt 10 weist vorzugsweise einen trapezförmigen oder dreieck- bzw. keilförmigen oder L-förmigen oder rechteckigen Querschnitt auf. Die jeweilige Nut 11 weist dementsprechend einen Querschnitt mit jeweils korrespondierendem Querschnitt auf.The insulating webs 8 and 9 are preferably web-shaped in cross section and have thickened end sections 10. In this case, each of the end sections 10 preferably engages in a corresponding groove 11 of one of the metal profiles 2, 4, 6, with the groove walls the thickened end sections 10 of the insulating webs 8, 9 in the x and y directions (see coordinate system in Fig. 1 ) preferably grip around positively. The respective end section 10 preferably has a trapezoidal or triangular or wedge-shaped or L-shaped or rectangular cross section. The respective groove 11 accordingly has a cross section with a respective corresponding cross section.

Um eine schubfeste und damit zusätzlich kraftschlüssige Verbindung zwischen dem jeweiligen Endabschnitt 10 und der jeweiligen Nut 11 zu erhalten, ist es vorteilhaft, wenn die jeweiligen Endabschnitte 10 in die jeweilige Nut 11 eingeklebt oder mit einem Draht eingesetzt oder mit einer anderen geeigneten Fügeverfahren in die Nut 11 eingesetzt sind, was die Schubfestigkeit in Profilrichtung (senkrecht zur Zeichenebene der Fig. 1), hervorgerufen durch eine Formschlusswirkung, erhöht.In order to obtain a shear-proof and thus additionally non-positive connection between the respective end section 10 and the respective groove 11, it is advantageous if the respective end sections 10 are glued into the respective groove 11 or inserted into the groove with a wire or another suitable joining method 11 are used, which increases the shear strength in the direction of the profile (perpendicular to the plane of the drawing Fig. 1 ), caused by a form-fit effect, increased.

In Fig. 1 weist -beispielhaft - die zweite Isolierstegzone II die zweiten Isolierstege 9 auf, deren jeweiligen Endabschnitte 10 form- und kraftschlüssig mit der jeweiligen Nut 11 verbunden sind, so dass sich jeweils eine insbesondere auch in z-Richtung (vgl. Koordinatensystem in Fig. 1) bzw. in einer Richtung orthogonal zur Querschnittsebene des Verbundprofils 1 schubfeste Verbindung zwischen den zweiten Isolierstegen 9 und den ihnen benachbarten äußeren und mittleren Metallprofilen ergibt. Diese Verbindung wird nachfolgend auch als schubfeste Ausbildung der einen der beiden - hier der zweiten - Isolierstegzonen bezeichnet. Sie bietet eine Schubfestigkeit gegen die infolge von Dilatation an einem Fenster oder einer Tür oder dgl. auftretenden Kräfte.In Fig. 1 has - for example - the second insulating web zone II on the second insulating webs 9, the respective end sections 10 of which are positively and non-positively connected to the respective groove 11, so that each one, in particular, also in the z-direction (see coordinate system in Fig. 1 ) or in a direction orthogonal to the cross-sectional plane of the composite profile 1 results in a shear-proof connection between the second insulating webs 9 and the outer and middle metal profiles adjacent to them. This connection is hereinafter also referred to as a shear-resistant design of one of the two - here the second - insulating web zones. It offers a shear strength against the forces occurring as a result of dilation on a window or a door or the like.

Die Schubfestigkeit der anderen - hier der ersten - Isolierstegzone I ist demgegenüber in sämtlichen Varianten geringer als die der ersten Isolierstegzone II. Sie ist derart gewählt, dass ein Verschieben von wenigstens zwei Elementen in der Isolierstegzone relativ zueinander infolge von Dilatation möglich ist. Vorzugsweise liegt die Isolierstegzone I geringerer Schubfestigkeit im Einbauzustand an einem Fenster oder einer Tür zu einer Gebäudeaußenseite hin, da hier die Temperaturdifferenzen größer sind als an der Gebäudeinnenseite, so dass hier die geringere Schubfestigkeit zum Ausgleich von Dilatationseffekten besonders wichtig ist. Zur Rauminnenseite hin liegt dagegen vorzugsweise die Isolierstegzone mit erhöhter Schubfestigkeit. Diese Variante der Erfindung ist besonders vorteilhaft. Allerdings ist es auch denkbar, die Isolierstegzone höherer Schubfestigkeit zur Raumaußenseite hin vorzusehen.In contrast, the shear strength of the other - here the first - insulating web zone I is lower in all variants than that of the first insulating web zone II. It is selected so that at least two elements in the insulating web zone can be moved relative to one another due to dilation. The insulating web zone I of lower shear strength is preferably located on a window or door on the outside of the building when installed, since the temperature differences are greater here than on the inside of the building, so that the lower shear strength is particularly important here to compensate for dilatation effects. On the other hand, the insulating web zone with increased shear strength is preferably located on the inside of the room. This variant of the invention is particularly advantageous. However, it is also conceivable to provide the insulating web zone with higher shear strength on the outside of the room.

Die erste Isolierstegzone I weist vorzugsweise - siehe Fig. 1 - Isolierstege 8 auf, die an einem ihrer beiden Enden jeweils einen ersten Endabschnitt 10 aufweisen, der form- und kraftschlüssig mit der jeweiligen Nut 11 verbunden ist, so dass sich jeweils eine insbesondere auch in z-Richtung (vgl. Koordinatensystem in Fig. 1) schubfeste Verbindung ergibt.The first insulating web zone I preferably has - see Fig. 1 - Insulating webs 8, which each have a first end section 10 at one of their two ends, which is positively and non-positively connected to the respective groove 11, so that in each case one in particular also extends in the z-direction (see coordinate system in Fig. 1 ) results in a shear-proof connection.

Die zweiten Enden der ersten Isolierstege 8 der ersten Isolierstegzone I weisen hingegen einen Endabschnitt 12 auf, der einen im Wesentlichen kederartigen Querschnitt hat. Der kederartige Querschnitt wird von einem Kederwulst 13 und einer Kederfahne 14 gebildet. Der Kederwulst 13 weist hier -rein beispielhaft - einen kreisförmigen Querschnitt auf. Der Kederwulst 13 kann alternativ auch einen unrunden oder ovalen oder polygonalen Querschnitt aufweisen. Der jeweilige Kederwulst 13 greift dabei in eine Nut 15 -hier ebenfalls rein beispielhaft- des ersten metallischen Außenprofils 2 ein, während die Kederfahne 14 aus einer Nutöffnung aus der Nut 15 herausgeführt ist, wobei die Nutwände die jeweiligen Endabschnitte 12 mit einen im Wesentlichen kederartigen Querschnitt der Isolierstege 8 in x- und y-Richtung (siehe Koordinatensystem in Fig. 1) formschlüssig umgreifen.The second ends of the first insulating webs 8 of the first insulating web zone I, on the other hand, have an end section 12 which has a substantially welt-like cross section. The welt-like cross section is formed by a welt bead 13 and a welt flap 14. The welt bead 13 here has - purely by way of example - a circular cross section. The welt bead 13 can alternatively also have a non-circular or oval or polygonal cross section. The respective welt bead 13 engages in a groove 15 - here also purely by way of example - of the first metallic outer profile 2, while the welt flap 14 is guided out of a groove opening out of the groove 15, the groove walls of the respective end sections 12 having a substantially welt-like cross section of the insulating bars 8 in the x and y directions (see coordinate system in Fig. 1 ) grip positively.

Der Endabschnitt 12 mit einen im Wesentlichen kederartigen Querschnitt ist - abweichend vom Endabschnitt 10- jedoch nicht schubfest mit der Nut 15 verbunden, so dass eine in z-Richtung (siehe Koordinatensystem in Fig. 1) schubverringerte Verbindung - im Stand der Technik synonym auch schubweiche oder schublose Verbindung genannt - geschaffen wird, welche vorteilhaft temperaturbedingte Verformungen des ersten metallischen Außenprofils 2 aufnehmen kann. In Fig. 5, 6 und 7 sind erfindungsgemäße Ausprägungen einer schubweichen oder schublosen Verbindung im Endabschnitt 12 eines Isolierstegs 8 dargestellt.The end section 12 with an essentially welt-like cross-section is - in contrast to the end section 10 - but not connected to the groove 15 in a shear-proof manner, so that one in the z-direction (see coordinate system in Fig. 1 ) a shear-reduced connection - also referred to synonymously in the prior art as a shear-soft or shearless connection - is created, which can advantageously absorb temperature-related deformations of the first metallic outer profile 2. In Fig. 5 , 6th and 7th expressions according to the invention of a shear-soft or shearless connection in the end section 12 of an insulating web 8 are shown.

Dadurch wird ein Verbundprofil 1 geschaffen, dass in der ersten Isolierstegzone I jeweils eine in Bezug auf die z-Richtung (vgl. Koordinatensystem in Fig. 1) relativ zur anderen Isolierstegzone schubverringerte, insbesondere schubweiche oder schublose, Verbindung zwischen dem ersten metallischen Außenprofil 2 und den Isolierstegen 8 bzw. dem metallischen Mittelprofil 6 aufweist, während die zweite Isolierstegzone II jeweils eine schubfeste Verbindung zwischen dem zweiten metallischen Außenprofil 4 und den Isolierstegen 9 bzw. dem metallischen Mittelprofil 6 aufweist.This creates a composite profile 1 that in the first insulating web zone I has one in each case in relation to the z-direction (see coordinate system in Fig. 1 ) has a shear-reduced, in particular shear-soft or shearless connection between the first metallic outer profile 2 and the insulating webs 8 or the metallic middle profile 6 relative to the other insulating web zone, while the second insulating web zone II has a shear-resistant connection between the second metallic outer profile 4 and the insulating webs 9 or the metallic middle profile 6.

Alternativ kann ein erfindungsgemäßes Verbundprofil 1 auch in der zweiten Isolierstegzone II eine schubverringerte, d.h. schubweiche oder schublose, Verbindung zwischen dem zweiten metallischen Außenprofil 4 und den Isolierstegen 9 bzw. dem metallischen Mittelprofil aufweisen, während die erste Isolierstegzone I eine relativ zur schubverringerten schubfeste(re) Verbindung zwischen dem ersten metallischen Außenprofil 2 und den Isolierstegen 8 bzw. dem metallischen Mittelprofil 6 aufweist.Alternatively, a composite profile 1 according to the invention can also have a shear-reduced, i.e. have a shear-soft or shearless connection between the second metallic outer profile 4 and the insulating webs 9 or the metallic middle profile, while the first insulating web zone I has a relatively shear-resistant connection between the first metallic outer profile 2 and the insulating webs 8 or the metallic one Has central profile 6.

Hierdurch ergibt sich ein Verbundprofil 1, das temperaturbedingte Verformungen durch eine schubweiche oder schublose Verbindung von einem der metallischen Außenprofile 2, 4 und den jeweiligen Isolierstegen 8, 9 bzw. mit dem metallischen Mittelprofil 6 ausgleichen kann sowie -überraschender Weise- ein Verbundprofil 1 mit einem hohen Flächenträgheitsmoment bzw. Flächenmoment 2. Grades.This results in a composite profile 1 that can compensate for temperature-related deformations due to a shear-soft or shearless connection of one of the metallic outer profiles 2, 4 and the respective insulating webs 8, 9 or with the metallic middle profile 6 and, surprisingly, a composite profile 1 with a high area moment of inertia or area moment of the 2nd degree.

In einer weniger bevorzugten Ausführungsform der vorliegenden Erfindung kann das Verbundprofil 1 auch in beiden Isolierstegzonen I, II in Bezug auf die z-Richtung (vgl. Koordinatensystem in Fig. 1) jeweils eine schubweiche oder schublose Verbindung der metallischen Außenprofile 2, 4 und den jeweiligen Isolierstegen 8, 9 bzw. mit dem metallischen Mittelprofil 6 aufweisen.In a less preferred embodiment of the present invention, the composite profile 1 can also be used in both insulating web zones I, II in relation to the z-direction (cf. coordinate system in FIG Fig. 1 ) a flexible or non-flexible connection of the metallic outer profiles 2, 4 and the respective insulating webs 8, 9 or with the metallic middle profile 6.

Das erste metallische Außenprofil 2 ist von dem metallischen Mittelprofil 6 vorzugsweise über eine Hohlkammer 16 getrennt, die in der ersten Isolierstegzone I zwischen den beiden ersten Isolierstegen 8 und den angrenzenden Metallprofilen ausgebildet wird, während das metallische Mittelprofil 6 von dem zweiten metallischen Außenprofil 4 über eine Hohlkammer 17 getrennt ist, die in der zweiten Isolierstegzone II zwischen den zweiten Isolierstegen 9 und den angrenzenden Metallprofilen liegt. Dadurch sind von einer Außenseite des ersten metallischen Außenprofils 2 zu einer zweiten Außenseite des zweiten metallischen Außenprofils 4 eine Vielzahl von Hohlkammern 3, 16, 7, 17 und 5 ausgebildet, die für eine gute Wärmedämmung sorgen.The first metallic outer profile 2 is separated from the metallic central profile 6 preferably via a hollow chamber 16 which is formed in the first insulating web zone I between the two first insulating webs 8 and the adjacent metal profiles, while the metallic central profile 6 is separated from the second metallic outer profile 4 via a Hollow chamber 17 is separated, which is located in the second insulating web zone II between the second insulating webs 9 and the adjacent metal profiles. As a result, a plurality of hollow chambers 3, 16, 7, 17 and 5 are formed from an outer side of the first metallic outer profile 2 to a second outer side of the second metallic outer profile 4, which provide good thermal insulation.

Die metallischen Außenprofile 2 und 4 weisen an gegenüberliegenden Seiten nach außen hervorstehende Stege 18 und 19 auf, wobei endseitig an dem Steg 18 eine Nut 20 zur Aufnahme einer Dichtung und an dem Steg 19 eine weitere Nut 21 zur Aufnahme einer Dichtung vorgesehen ist. Je nach Funktionsart (Flügel- oder Blendrahmen) können die Stege 18 und 19 auch an einer Seite, nur einer dieser Stege oder keiner dieser Stege vorhanden sein.The metallic outer profiles 2 and 4 have outwardly protruding webs 18 and 19 on opposite sides, with a groove 20 for receiving a seal on the end of the web 18 and a further groove 21 for receiving a seal on the web 19. Depending on the type of function (sash or frame), the webs 18 and 19 can also be present on one side, only one of these webs or none of these webs.

In Fig. 2 bzw. in Fig. 3 und 4 ist jeweils eine weitere Ausführungsvariante eines Verbundprofils nach Fig. 1 dargestellt.In Fig. 2 or in Figures 3 and 4 is a further variant of a composite profile according to Fig. 1 shown.

In Fig. 3 ist eine Ausführungsvariante des Kederwulstes 13 bzw. 23 dargestellt. In Fig. 3 weist der Kederwulst 13 bzw. 23 eine kreisförmige Querschnittsgeometrie auf. Alternativ kann die Querschnittsgeometrie des Kederwulstes 13 bzw. 23 auch oval, elipsenförmig oder polygonal ausgeführt sein.In Fig. 3 a variant of the Keder bead 13 or 23 is shown. In Fig. 3 if the welt bead 13 or 23 has a circular cross-sectional geometry. Alternatively, the cross-sectional geometry of the welt bead 13 or 23 can also be oval, elliptical or polygonal.

Darüber hinaus kann der Kederwulst 13 bzw. 23 an seiner Oberfläche eine co-extrudierte Folie oder Schicht aufweisen. Die co-extrudierte Folie kann beispielsweise so auf gebaut sein, dass die Folie, die mit der Nut 15 des ersten metallischen Außenprofil 2 bzw. mit dem zweiten metallische Außenprofil 4 bzw. mit der Nut 25 im Isoliersteg 22 in Kontakt kommt, einen geringen Reibbeiwert aufweist, während die andere Folie oder Schichtseite, die mit dem Isoliersteg 8, 22 in Kontakt kommt, eine feste Verbindung mit dem Isoliersteg 8, 22 eingeht. Durch die co-extrudierte Folie wird demnach insgesamt eine fest mit dem jeweiligen Isoliersteg 8, 22 verbundene Schicht mit einem besonders geringen Reibwert im Bereich des Kederwulstes 13 bzw. 23 geschaffen, so dass in z-Richtung (siehe Koordinatensystem in Fig. 1 bzw. Fig. 2) quasi eine schublose oder schubweiche Verbindung geschaffen wird.In addition, the welt bead 13 or 23 can have a co-extruded film or layer on its surface. The co-extruded film can be constructed, for example, so that the film that comes into contact with the groove 15 of the first metallic outer profile 2 or with the second metallic outer profile 4 or with the groove 25 in the insulating web 22 has a low coefficient of friction has, while the the other film or layer side that comes into contact with the insulating web 8, 22 enters into a firm connection with the insulating web 8, 22. The co-extruded film accordingly creates a layer that is firmly connected to the respective insulating web 8, 22 and has a particularly low coefficient of friction in the area of the welt bead 13 or 23, so that in the z-direction (see coordinate system in Fig. 1 or. Fig. 2 ) a quasi-thrust-free or thrust-soft connection is created.

In Fig. 4 ist eine Nut 15 bzw. 25 an einem Metallprofil oder einem Isolierstegabschnitt dargestellt. Die Nut 15 bzw. 25 weist eine kreisförmige Querschnittsgeometrie auf. Alternativ kann die Querschnittsgeometrie der Nut 15 bzw. 25 auch oval, elipsenförmig oder polygonal ausgeführt sein, dies ist abhängig von der gewählten Querschnittsgeometrie des Kederwulstes 13 bzw. 23, mit der die Querschnittsgeoemetrie der Nut 15 bzw. 25 korrespondiert. In einer alternativen Ausführungsform kann die Nut 15 bzw. 25 eine kerbverzahnungsnabenähnliche Querschnittsgeometrie 31 oder eine keilwellennabenähnliche Querschnittsgeometrie aufweisen.In Fig. 4 a groove 15 or 25 is shown on a metal profile or an insulating web section. The groove 15 or 25 has a circular cross-sectional geometry. Alternatively, the cross-sectional geometry of the groove 15 or 25 can also be oval, elliptical or polygonal; this depends on the selected cross-sectional geometry of the welt bead 13 or 23, with which the cross-sectional geometry of the groove 15 or 25 corresponds. In an alternative embodiment, the groove 15 or 25 can have a splined hub-like cross-sectional geometry 31 or a splined hub-like cross-sectional geometry.

Durch einen Kontakt durch mehrere Zähne 32 einer Kerbverzahnungsnabe 31 bzw. mehrerer Keile (hier nicht dargestellt) der Nut 15 bzw. 25 im ersten metallische Außenprofil 2 bzw. im zweiten metallischen Außenprofil 4 bzw. im Isoliersteg 22 ergibt sich eine reibungsarme Verbindung zwischen dem Isoliersteg 8, 22 und der Nut 15 bzw. 25 in dem jeweiligen metallischen Außenprofil 2, 4, bzw. im Isoliersteg 22 so dass eine in z-Richtung (siehe Koordinatensystem in Fig. 1 bzw. Fig. 2) schubweiche Verbindung geschaffen wird. Darüber hinaus tragen die Zähne der Kerbverzahnungsnabe bzw. die Keile der Keilwellennabe zum Toleranzausgleich zwischen dem Kederwulst 13 bzw. 23 und der Nut 15 bzw. 25 bei.Contact by several teeth 32 of a serration hub 31 or several wedges (not shown here) of the groove 15 or 25 in the first metallic outer profile 2 or in the second metallic outer profile 4 or in the insulating web 22 results in a low-friction connection between the insulating web 8, 22 and the groove 15 or 25 in the respective metallic outer profile 2, 4 or in the insulating web 22 so that one in the z-direction (see coordinate system in Fig. 1 or. Fig. 2 ) a flexible connection is created. In addition, the teeth of the serration hub or the wedges of the splined shaft hub contribute to the tolerance compensation between the Keder bead 13 or 23 and the groove 15 or 25.

Nachfolgend wird in Hinsicht auf die Ausbildung der Kederverbindung am Isoliersteg 8 und am zugeordneten Metallprofil 2, 4, 6 näher der Stand der Technik nach Fig. 13 und 14 betrachtet.The prior art is described in more detail below with regard to the formation of the welt connection on the insulating web 8 and on the associated metal profile 2, 4, 6 Fig. 13 and 14th considered.

Figur 13 und 14 zeigen den Stand der Technik schematisch vor und nach dem Anrollen von an den Metallprofilen 2, 4, 6 ausgebildeten Stegen an den Isoliersteg 8. Figure 13 and 14th show the prior art schematically before and after the webs formed on the metal profiles 2, 4, 6 are rolled onto the insulating web 8.

Figur 13 zeigt den Stand der Technik der EP 0 829 609 A2 entsprechend der Figur 4, jedoch vor der Montage. Der schublose Verbundbereich ist zum besseren Verständnis mit einem besonders großen Toleranzbereich dargestellt (Spalt). Auf der schubfesten Seite werden die Toleranzen, bzw. der Spalt, nach der Montage der sechs Meter langen Profile durch das Anrollen des Steges ausgeglichen. Dabei wird eine Kraft F auf den Steg des jeweiligen Metallprofils 2, 4, 6 aufgebracht, um eine plastische Verformung des Stegs zu erzielen, bis der Steg zur Anlage an den Isoliersteg 8 kommt und so im Fall einer schubfesten Verbindung zwischen dem Isoliersteg 8 bzw. zwischen dem Endstück 10 des Isolierstegs 8 und der Nut 11 eine form- und kraftschlüssige Verbindung in Bezug auf eine Verformungsrichtung in Profilebene bzw. in z-Richtung in Bezug auf das Koordinatensystem in Fig. 1 bzw. Fig. 2 geschaffen wird. Figure 13 shows the prior art of EP 0 829 609 A2 according to the Figure 4 , but before assembly. For better understanding, the non-thrust bond area is shown with a particularly large tolerance range (gap). On the shear-resistant side, the tolerances, or the gap, are compensated for after the six-meter-long profiles have been installed by rolling the web. A force F is applied to the web of the respective metal profile 2, 4, 6 in order to achieve a plastic deformation of the web until the web comes into contact with the insulating web 8 and so in the case of a shear-resistant connection between the insulating web 8 or between the end piece 10 of the insulating web 8 and the groove 11 a positive and non-positive connection with respect to a deformation direction in the profile plane or in the z-direction with respect to the coordinate system in Fig. 1 or. Fig. 2 is created.

Die Darstellung in Fig. 14 veranschaulicht ein Verkanten des Isoliersteges 8 durch das Anrollen aufgrund der erforderlichen großen Toleranzen und das dadurch einhergehende große Spiel, wodurch das Verbundprofil nach dem Stand der Technik insgesamt für Tür- oder Fenster-Konstruktionen nicht geeignet ist. Das Verkanten blockiert die Schub-Beweglichkeit, das große Spiel schränkt die Maßhaltigkeit des Verbundprofils ein und reduziert die statische Belastbarkeit des Verbundprofils.The representation in Fig. 14 illustrates tilting of the insulating web 8 due to the rolling due to the large tolerances required and the resulting large play, whereby the composite profile according to the prior art is not suitable overall for door or window constructions. The tilting blocks the shear mobility, the large play limits the dimensional accuracy of the composite profile and reduces the static load-bearing capacity of the composite profile.

Figur 5 zeigt demgegenüber einen ersten erfindungsgemäßen Isoliersteg 8a mit C-förmiger Querschnittsgeometrie. Der Isoliersteg 8a kennzeichnet sich durch einen schublosen Bereich A und einen schubfesten Bereich B. Insgesamt weist der Isoliersteg 8a in etwa eine C-förmige Querschnittsgeometrie auf, wobei der schublose Bereich einen Kederwulst 13 mit einer kreissektorförmigen Querschnittsgeometrie aufweist. Der Kederwulst 13 kann auch andere geeignete Querschnittsgeometrien aufweisen, zum Beispiel T-förmig, dreieckförmig oder jede beliebige andere geeignete Geometrie, wie z.B. in Fig. 3 dargestellt. Als besonders vorteilhaft hat sich allerdings eine in etwa kreissektorförmige Querschnittsgeometrie herausgestellt. Figure 5 shows a first insulating web 8a according to the invention with a C-shaped cross-sectional geometry. The insulating web 8a is characterized by a thrustless area A and a shear-resistant area B. Overall, the insulating web 8a has an approximately C-shaped cross-sectional geometry, the non-thrusting area having a welt bead 13 with a sector-shaped cross-sectional geometry. The welt bead 13 can also have other suitable cross-sectional geometries, for example T-shaped, triangular or any other suitable geometry, such as in FIG Fig. 3 shown. However, an approximately sector-shaped cross-sectional geometry has proven to be particularly advantageous.

Der Isoliersteg 8a weist dementsprechend eine Ausnehmung 105 auf, die in Bezug auf die Zeichenebene der Fig. 1 bzw. Fig. 2 und der Fig. 5 nach unten, bzw. in Richtung negativer y-Werte in Bezug auf das Koordinatensystem in Fig. 1 geöffnet ist, so dass sich eine C-förmige Querschnittsgeometrie für den Stegabschnitt zwischen den beiden Metallprofilen 2, 4, 6 ergibt.The insulating web 8a accordingly has a recess 105, which in relation to the plane of the drawing Fig. 1 or. Fig. 2 and the Fig. 5 downwards or in the direction of negative y-values in relation to the coordinate system in Fig. 1 is open so that a C-shaped cross-sectional geometry results for the web section between the two metal profiles 2, 4, 6.

Der Isoliersteg 8a weist eine Stegbreite "w" sowie eine Gesamtbreite "W" auf. Die Stegbreite "w" entspricht in etwa der Hälfte der Gesamtbreite "W" des Isoliersteges 8a. Die Stegbreite "w" kann auch noch etwas geringer gewählt werden. Der Isoliersteg 8a weist eine Länge "u" und eine Gesamtlänge "U" auf. Die Länge "u" entspricht in etwa ein Viertel der Gesamtlänge "U". Hierdurch ergibt sich eine definierte Verformbarkeit des Isolierstegs 8a über den "Rücken" des C-förmigen Querschnitts.The insulating web 8a has a web width "w" and an overall width "W". The web width "w" corresponds approximately to half of the total width "W" of the insulating web 8a. The web width "w" can also be chosen to be somewhat smaller. The insulating web 8a has a length “u” and an overall length “U”. The length "u" corresponds approximately to a quarter of the total length "U". This results in a defined deformability of the insulating web 8a over the "back" of the C-shaped cross section.

Erfindungswesentlich ist, dass jeder erfindungsgemäße Isoliersteg die oben definierten und in den Fig. 5 bis Fig. 9 bemaßten Geometrieausprägungen aufweist.
Der Isoliersteg 8a weist auf der Seite mit dem Kederwulst 13 eine obere Schulter 101 und eine untere Schulter 102 zur Anlage an dem metallischen Profil 2, 4, 6 auf. anders ausgedrückt grenzen die Schultern 101 und 102 an das Metallprofil 2, 4, 6.It is essential to the invention that each insulating web according to the invention are those defined above and in the FIGS. 5 to 9 has dimensioned geometric characteristics.
On the side with the welt bead 13, the insulating web 8a has an upper shoulder 101 and a lower shoulder 102 for contact with the metallic profile 2, 4, 6. In other words, the shoulders 101 and 102 adjoin the metal profile 2, 4, 6.

Ein Bereich, der den Endabschnitt 10 zur Ausbildung einer schubfesten Verbindung aufweist ist hier mit "B" gekennzeichnet. Der Bereich "B" des Isolierstegs 8a weist eine Schräge 103 auf. Die Schräge 103 weist bevorzugt einen Winkel von 5° bis 50°, besonders bevorzugt einen Winkel von 15° bis 45° zur Haupterstreckungsrichtung des Isolierstegs 8a auf, die hier mit der x-Achse des Koordinatensystems in Fig. 1 zusam menfällt.An area which has the end section 10 to form a shear-proof connection is identified here with "B". The area “B” of the insulating web 8 a has a slope 103. The bevel 103 preferably has an angle of 5 ° to 50 °, particularly preferably an angle of 15 ° to 45 °, to the main direction of extent of the insulating web 8a, which is here with the x-axis of the coordinate system in FIG Fig. 1 coincides.

Diese Schräge 103 des Isolierstegs 8a kommt eine besondere Bedeutung zu. Der Isoliersteg 8a wird beim Anrollen der Isolierstege 8 im Metallprofil 2, 4, 6 über die Schräge 103 aus seiner geometrisch idealen Lage (hier horizontal) herausgedrückt. Der Isoliersteg 8a wölbt sich durch das Anrollen insgesamt, bzw. wird durch das Anrollen aus seiner geometrischen Solllage (hier horizontal) gebracht. Dadurch wird der Endabschnitt 10 aus der Horizontalen bzw. aus einer Ebene parallel zur x-Achse in Bezug auf das Koordinatensystem in Fig. 1 um einen Winkel α (hier nicht dargestellt) geneigt. Die Neigungsrichtung definiert sich dabei über die Verformbarkeit und damit über die Querschnittsgeometrie des Isolierstegs 8a. Darüber hinaus grenzt eine hier nicht bezeichnete Schulter auf der Seite des Endabschnitts 10 des Isolierstegs 8a ebenfalls an das Metallprofil 2, 4,6 an bzw. liegt diese Schulter an dem Metallprofil 2, 4, 6 im montierten Zustand des Isolierstegs 8a an.This slope 103 of the insulating web 8a is of particular importance. The insulating web 8a is pressed out of its geometrically ideal position (here horizontally) when the insulating webs 8 in the metal profile 2, 4, 6 are rolled onto the bevel 103. The insulating web 8a arches as a whole as a result of the rolling, or is brought out of its desired geometric position (here horizontal) by the rolling. As a result, the end section 10 is out of the horizontal or out of a plane parallel to the x-axis with respect to the coordinate system in FIG Fig. 1 inclined by an angle α (not shown here). The direction of inclination is defined by the deformability and thus by the cross-sectional geometry of the insulating web 8a. In addition, a shoulder (not designated here) borders on the side of the end section 10 of the insulating web 8a likewise on the metal profile 2, 4, 6 or this shoulder rests on the metal profile 2, 4, 6 in the assembled state of the insulating web 8a.

Die Neigung des Endabschnitts 10 bzw. des Bereichs "B" des Isolierstegs 8a ist insbesondere wichtig im Zusammenspiel mit der gegenüberliegenden schublosen Seite des Isolierstegs 8a, deren Bereich hier mit dem Buchstaben "A" gekennzeichnet ist und wird weiter unten näher erläutert.The inclination of the end section 10 or the area "B" of the insulating web 8a is particularly important in interaction with the opposite non-thrust side of the insulating web 8a, the area of which is identified here with the letter "A" and is explained in more detail below.

Die Ausführungsform des Isolierstegs 8b nach Fig. 6 entspricht der Ausführungsform des Isolierstegs 8a nach Fig. 5 (C-Form nach unten geöffnet), jedoch ergänzt um eine weitere Schulter 104, die im Bereich "B" also auf der Seite des Endabschnitts 10 angeordnet ist. Hierdurch ergibt sich eine symmetrische Ausnehmung 105, die sich vorteilhaft z.B. zur Aufnahme für einen Schaum zur zusätzlichen thermischen Isolierung eignet. Insofern weist der Isoliersteg 8b zwischen den Schultern 101, 102 bzw. 104, die im montierten Zustand des Isolierstegs 8b an das Metallprofil 2, 4, 6 grenzen bzw. an dem Metallprofil 2, 4, 6 anliegen, aber auch über seine ganze Länge nebst beider Endabschnitte 10, 13 eine C-förmige Querschnittsgeometrie auf.The embodiment of the insulating web 8b according to Fig. 6 corresponds to the embodiment of the insulating web 8a Fig. 5 (C-shape opened downwards), but supplemented by a further shoulder 104, which is arranged in the area “B” on the side of the end section 10. This results in a symmetrical recess 105, which is advantageously suitable, for example, for receiving a foam for additional thermal insulation. In this respect, the insulating web 8b has between the shoulders 101, 102 and 104, which in the assembled state of the insulating web 8b border on the metal profile 2, 4, 6 or rest against the metal profile 2, 4, 6, but also along its entire length both end sections 10, 13 have a C-shaped cross-sectional geometry.

Figur 7 zeigt einen Isoliersteg 8c mit doppelt C-förmiger Querschnittsgeometrie oder auch Z-förmiger Querschnittsgeometrie zwischen den Schultern 101, 102 bzw. 104, die im montierten Zustand des Isolierstegs 8c an das Metallprofil 2, 4, 6 grenzen bzw. an dem Metallprofil 2, 4, 6 anliegen. Demzufolge weist der Isoliersteg 8c zwei Ausnehmungen 105 und 105' auf, die in Bezug auf die Zeichnungsebene wechselseitig nach oben und nach unten geöffnet sind. Die Gesamtbreite "W" behält auch in dieser Ausführungsform des Isolierstegs 8c ihr Verhältnis zur Stegbreite "w" bei. Durch die hier gewählte doppelt C-förmige bzw. Z-förmige Querschnittsgeometrie des Isolierstegs 8c wird eine definierte Verformbarkeit des Isolierstegs 8c gewährleistet. Figure 7 shows an insulating web 8c with a double C-shaped cross-sectional geometry or also Z-shaped cross-sectional geometry between the shoulders 101, 102 and 104, which in the assembled state of the insulating web 8c border on the metal profile 2, 4, 6 or on the metal profile 2, 4 , 6 are applied. Accordingly, the insulating web 8c has two recesses 105 and 105 'which are open alternately upwards and downwards with respect to the plane of the drawing. In this embodiment of the insulating web 8c too, the total width “W” retains its ratio to the web width “w”. The double C-shaped or Z-shaped cross-sectional geometry of the insulating web 8c selected here ensures a defined deformability of the insulating web 8c.

Figur 8 zeigt einen Isoliersteg 8d nach Figur 6. Der Isoliersteg weist eine in Bezug auf die Zeichenebene der Fig. 8 und der Fig. 6 nach oben hin geöffneten Ausnehmung 105 auf, so dass sich für den Isoliersteg 8d eine C-förmige Querschnittsgeometrie zwischen den Schultern 101, 102 bzw. 104, die im montierten Zustand des Isolierstegs 8d an das Metallprofil 2, 4, 6 grenzen bzw. an dem Metallprofil 2, 4, 6 anliegen, aber auch über seine ganze Länge nebst beider Endabschnitte 10, 13, ergibt. Figure 8 shows an insulating web 8d Figure 6 . The insulating bar has one in relation to the plane of the drawing Fig. 8 and the Fig. 6 upwardly open recess 105, so that for the insulating web 8d a C-shaped cross-sectional geometry between the shoulders 101, 102 and 104, which in the assembled state of the insulating web 8d border on the metal profile 2, 4, 6 or on the Metal profile 2, 4, 6, but also over its entire length together with both end sections 10, 13 results.

Figur 9 zeigt einen Isoliersteg 8e nach Art der Figur 8, jedoch in einer besonders bevorzugten Ausführung, bei der die Aufnahme 105 durch zusätzliche Stege 110 und 111 als Aufnahme 105 mit hinterschnittener Querschnittsgeometrie ausgebildet ist. Auf diese Art wird auf eine einfache und damit vorteilhafte Weise die Aufnahme bzw. Positionierung und Befestigung von zusätzlichen Bauteilen bzw. Falzelementen ermöglicht. Hierzu gehören insbesondere Dichtungen. Figure 9 shows an insulating web 8e of the type Figure 8 , but in a particularly preferred embodiment in which the receptacle 105 is formed by additional webs 110 and 111 as a receptacle 105 with an undercut cross-sectional geometry. In this way, the inclusion or positioning and fastening of additional components or folding elements is made possible in a simple and therefore advantageous manner. This includes in particular seals.

Figur 10 zeigt die Nut 15a für die Aufnahme des Kederwulstes 13 bzw. des Bereichs "A" des erfindungsgemäßen Isolierstegs 8a, 8b, 8c, 8d, 8e im metallischen Profil 2, 4, 6. Figure 10 shows the groove 15a for receiving the welt bead 13 or the area “A” of the inventive insulating web 8a, 8b, 8c, 8d, 8e in the metallic profile 2, 4, 6.

Die Nut 15a kennzeichnet sich durch einen Anlagebereich 121 und einen Anlagebereich 122, wobei sich in Bezug auf die Zeichenebene der Fig. 10 unter dem Anlagebereich 122 bzw. ausgehend vom Anlagebereich 122 in Richtung negativer y-Werte in Bezug auf das Koordinatensystem in Fig. 1 ein Radius "R" befindet. Der zweite Anlagebereich geht damit in einen abgerundeten Abschnitt mit dem Radius R über. Derart befindet sich unter dem Anlagebereich 22 der Radius "R".The groove 15a is characterized by an abutment area 121 and an abutment area 122, with respect to the plane of the drawing Fig. 10 below the contact area 122 or starting from the contact area 122 in the direction of negative y-values with respect to the coordinate system in FIG Fig. 1 a radius "R" is located. The second contact area thus merges into a rounded section with the radius R. In this way, the radius "R" is located under the contact area 22.

Mit dem Begriff "Anlagebereich" ist der Bereich an der Nut 15 bzw. 15a im Metallprofil 2, 4, 6, die von dem Kederwulst 13 durchgriffen wird, zu verstehen, an dem sich die Schultern 101, 102 des Isolierstegs 8a, 8b, 8c, 8d, 8e am Metallprofil 2, 4, 6 abstützen, bzw. an dem die Schultern 101, 102 des Isolierstegs 8a, 8b, 8c, 8d, 8e zur Anlage an das Metallprofil 2, 4, 6 kommen.The term “contact area” is to be understood as the area on the groove 15 or 15a in the metal profile 2, 4, 6 through which the welt bead 13 extends, on which the shoulders 101, 102 of the insulating web 8a, 8b, 8c , 8d, 8e on the metal profile 2, 4, 6, or on which the shoulders 101, 102 of the insulating web 8a, 8b, 8c, 8d, 8e come to rest on the metal profile 2, 4, 6.

Der Radius "R" entspricht in etwa dem Radius des Kreissektors des kreissektorförmigen Kederwulstes 13. Dies bedeutet, dass der Radius des Kederwulstes sich vorzugsweise nicht um mehr als 30% von dem Radius R am zweiten Anlagebereich unterscheidet. Hierdurch wird ein Abrollen des Isoliersteges 8a, 8b, 8c, 8d, 8e um den Radius "R" bzw. eine Drehbewegung des Isoliersteges 8a, 8b, 8c, 8d, 8e um den Mittelpunkt des Kreissektors des Kederwulstes 13 mit kreissektorförmigen Querschnitt ermöglicht.The radius "R" corresponds approximately to the radius of the circular sector of the sector-shaped welt bead 13. This means that the radius of the welt bead preferably does not differ by more than 30% from the radius R on the second contact area. This prevents the insulating web 8a, 8b, 8c, 8d, 8e from rolling around the radius "R" or a rotational movement of the insulating web 8a, 8b, 8c, 8d, 8e around the center of the circular sector of the welt bead 13 with a circular sector-shaped cross-section.

Der Betrag der Drehbewegung beträgt dabei die des Winkels a" an der Öffnungsseiten der Nut 15a. Der in Bezug auf die Zeichnungsebene obere Winkel a' bzw. der Winkel a' in Richtung positiver y-Werte in Bezug auf das Koordinatensystem in Fig. 1 wirkt im Zusammenspiel mit dem Anlagebereich 121 und der Schulter 101. Dadurch werden Toleranzen der zu fügenden Bauteile ausgeglichen bzw. wirken sich die Bauteiltoleranzen nicht negativ auf die Funktion der Kederverbindung bzw. der Gleitführung bzw. des schublosen Verbundes aus. Der in Bezug auf die Zeichnungsebene untere Winkel a" bzw. der Winkel a' in Richtung negativer y-Werte in Bezug auf das Koordinatensystem in Fig. 1 behält die Toleranz im Zusammenspiel mit dem Radius "R" und der Schulter 102 bei bzw. aufrecht.The amount of the rotary movement is that of the angle a "on the opening sides of the groove 15a. The upper angle a 'with respect to the plane of the drawing or the angle a' in the direction of positive y-values with respect to the coordinate system in FIG Fig. 1 acts in interaction with the contact area 121 and the shoulder 101. As a result, tolerances of the components to be joined are compensated for or the component tolerances do not have a negative effect on the function of the welt connection or the sliding guide or the non-thrust assembly. The lower angle a ″ with respect to the drawing plane or the angle a ′ in the direction of negative y values with respect to the coordinate system in Fig. 1 maintains the tolerance in conjunction with the radius "R" and the shoulder 102.

Figur 11 zeigt einen erfindungsgemäßen Isoliersteg 8e einseitig in die Nut 15a des metallischen Profils 2, 4, 6 eingeschoben. Dies ist rein beispielhaft zu verstehen, so dass das Folgende daher sinngemäß auch für den Isoliersteg 8a, 8b, 8c, 8d gilt. In Fig. 11 wird deutlich, dass auch bei entsprechend großen Bauteiltoleranzen ein ausreichender Raum, insbesondere in einer negativen Betragsrichtung (-) des Winkel α aufgrund des Radius "R" für eine einfache Montage vorhanden ist. In einer positiven Betragsrichtung (+) des Winkels α ist die Bewegung des Isoliersteges 8e allerdings eingeschränkt, da der Isoliersteg 8e bei Auslenkung in der positiven Betragsrichtung des Winkels α in dem Punkt "P" bereits nach kleiner Auslenkung mit seiner Schulter 101 zur Anlage an das Metallprofil 2, 4, 6 kommt, so dass eine weitere Auslenkung des Isolierstegs 8e nicht möglich ist und dem Isoliersteg 8e dadurch ein vorhandenes Spiel entzogen wird. Figure 11 shows an insulating web 8e according to the invention pushed into the groove 15a of the metallic profile 2, 4, 6 on one side. This is to be understood purely as an example, so that the following also applies accordingly to the insulating web 8a, 8b, 8c, 8d. In Fig. 11 it becomes clear that even with correspondingly large component tolerances, there is sufficient space for simple assembly, in particular in a negative direction (-) of the angle α due to the radius "R". In a positive direction (+) of the angle α, the movement of the insulating web 8e is restricted because the insulating web 8e when deflected in the positive direction of the angle α at the point "P" after a small deflection with its shoulder 101 to rest on the Metal profile 2, 4, 6 comes, so that a further deflection of the insulating web 8e is not possible and the insulating web 8e is thereby deprived of any play.

Figur 12 zeigt einen Profilverbund bzw. einen Ausschnitt eines erfindungsgemäßen Verbundprofils 1 im angerollten bzw. montierten Zustand. Durch das Anrollen wird eine Kraft F auf die Profilstege der metallischen Teilprofile 2, 4, 6 aufgebracht. Über die Schräge 103 erhalten die erfindungsgemäßen Isolierstege 8a, 8b, 8c, 8d, 8e, von denen hier -rein beispielhaft- jeweils ein Isoliersteg 8a und ein Isoliersteg 8e dargestellt ist, ein Drehmoment (+) zueinander. Ohne die Gegenseite (hier ein zweiter Isoliersteg 8a) würden der Isoliersteg 8e also leicht in Richtung Hohlkammer 16 bzw. 17 abgewinkelt sein (im spitzen Winkel zur dargestellten Horizontale bzw. zu einer Ebene parallel zur x-Achse nach dem Koordinatensystem in Fig. 1). Dieses entspricht nach der Fig. 12 einem Drehmoment in Richtung (+). Die Schrägen 103 sind in der doppelten Isoliersteganordnung gegenüberliegend, also wechselseitig angeordnet, während die C-förmige Öffnungen 105 in eine Richtung weisend angeordnet sind. Die C-förmige Ausnehmungen 105 sind hier in eine Richtung weisend angeordnet, um ihre zusätzlichen Funktionen nutzen zu können (z.B. Isolierschaumaufnahme und Dichtungsaufnahme). Eine Montage der Isolierstege 8a bzw. 8e mit in Bezug auf die Darstellung in Fig. 12 in entgegengesetzter Richtung weisender C-förmige Ausnehmung 105 ist aber auch möglich. Figure 12 shows a composite profile or a section of a composite profile 1 according to the invention in the rolled or assembled state. As a result of the rolling, a force F is applied to the profile webs of the metallic partial profiles 2, 4, 6. The insulating webs 8a, 8b, 8c, 8d, 8e according to the invention, of which an insulating web 8a and an insulating web 8e are shown here - purely by way of example - receive a torque (+) to one another via the bevel 103. Without the opposite side (here a second insulating web 8a), the insulating web 8e would therefore be slightly in the direction of the hollow chamber 16 or 17 be angled (at an acute angle to the horizontal line shown or to a plane parallel to the x-axis according to the coordinate system in Fig. 1 ). This corresponds to the Fig. 12 a torque in the (+) direction. The bevels 103 are arranged opposite one another in the double insulating bar arrangement, that is to say alternately, while the C-shaped openings 105 are arranged pointing in one direction. The C-shaped recesses 105 are arranged here pointing in one direction in order to be able to use their additional functions (for example insulating foam receptacle and seal receptacle). An assembly of the insulating webs 8a and 8e with reference to the representation in Fig. 12 However, a C-shaped recess 105 pointing in the opposite direction is also possible.

Die Drehmomente heben sich gegenseitig auf, wodurch eine exakte Profilgeometrie verwirklicht werden kann, ohne dass große Bauteiltoleranzen weiter ihre Wirkung beibehalten, die für die Montage erforderlich sind. Die Bauteiltoleranzen werden durch die vorliegende Erfindung quasi ausgehebelt. Es ist kein oder nur noch ein geringes Spiel zur Verwirklichung des schublosen Verbundes vorhanden.The torques cancel each other out, as a result of which an exact profile geometry can be achieved without the large component tolerances that are required for assembly still maintaining their effect. The component tolerances are virtually canceled out by the present invention. There is no or only a small amount of play to achieve the push-free connection.

Da das Drehmoment allein durch den Anrollprozess nicht oder nur sehr ungenau zu bestimmen ist, ist es besonders vorteilhaft, dass die Isolierstege 8a, 8b, 8c, 8d, 8e aufgrund ihrer insgesamt über ihre ganze Länge nebst beider Endabschnitte aber auch ihrem Stegabschnitt zwischen den Nuten der Metallprofile, bzw. zwischen den Schultern 101, 102 bzw. 104, die im montierten Zustand des Isoliersteges 8a, 8b, 8c, 8d, 8e an das Metallprofil 2, 4, 6 grenzen bzw. an dem Metallprofil 2, 4, 6 anliegen, C-förmigen Querschnittsgeometrie eine definierte Verformbarkeit aufweisen. Nur so kann verhindert werden, dass eine zu große Flächenpressung im Punkt "P" auftritt, wodurch die gewünschte Schubfestigkeit negativ beeinflusst wird und es eventuell sogar zu Beschädigungen der Verbindung kommen kann.Since the torque cannot be determined or can only be determined very imprecisely by the rolling process alone, it is particularly advantageous that the insulating webs 8a, 8b, 8c, 8d, 8e, due to their overall length over their entire length together with both end sections, but also their web section between the grooves of the metal profiles, or between the shoulders 101, 102 and 104, which in the assembled state of the insulating web 8a, 8b, 8c, 8d, 8e border on the metal profile 2, 4, 6 or rest against the metal profile 2, 4, 6 , C-shaped cross-sectional geometry have a defined deformability. This is the only way to prevent excessive surface pressure from occurring at point "P", which negatively affects the desired shear strength and can even damage the connection.

Folgende Größenverhältnisse des Isolierstegs 8a, 8b, 8c, 8d, 8e haben sich als besonders vorteilhaft im Sinne der Erfindung herausgestellt: Die Stegbreite "w" zur Gesamtbreite "W" des Isoliersteges 8a, 8b, 8c, 8d, 8e bevorzugt im Verhältnis "w"/"W" = 0,3 bis 0,5; besonders bevorzugt "w"/"W" = 0,5; die Länge "u" zur Gesamtlänge "U" des Isoliersteges 8a, 8b, 8c, 8d, 8e bevorzugt im Verhältnis "u"/"U" = 0,125; besonders bevorzugt "u"/"U" = 0,25.The following size ratios of the insulating web 8a, 8b, 8c, 8d, 8e have proven to be particularly advantageous in the context of the invention: The web width "w" to the total width "W" of the insulating web 8a, 8b, 8c, 8d, 8e, preferably in the ratio "w "/" W "= 0.3 to 0.5; particularly preferably "w" / "W" = 0.5; the length "u" to the total length "U" of the insulating web 8a, 8b, 8c, 8d, 8e preferably in the ratio "u" / "U" = 0.125; particularly preferably "u" / "U" = 0.25.
