Description

Die vorliegende Erfindung betrifft ein C-Profil aus Blech für beidseitig beplankte Trennwände mit zwei Schenkelabschnitten und einem die Schenkelabschnitte verbindenden Bodenabschnitt, wobei die Schenkelabschnitte Seitenflächen des C-Profils bilden und wobei wenigstens einer der Schenkelabschnitte nach außen vorspringende Sicken aufweist, welche eine Anlagefläche für die Beplankung bilden.The present invention relates to a C-profile made of sheet metal for partition walls planked on both sides with two leg sections and a bottom section connecting the leg sections, the leg sections forming side surfaces of the C-profile and at least one of the leg sections having outwardly projecting beads which have a contact surface for the Form planking.

Ein derartiges C-Profil, bei dem die Schenkelabschnitte mehrere parallele längsverlaufende, nach außen vorspringende Sicken aufweist, ist aus der DE 100 13 991 C1 bekannt.Such a C-profile, in which the leg sections have a plurality of parallel, longitudinal, outwardly projecting beads, is shown in FIG DE 100 13 991 C1 known.

Wenngleich bei unter Verwendung von solchen vorbekannten C-Profilen erstellten Trockenbauwänden mittlerweile gute Schallisolierungswerte erreicht werden können, besteht der Wunsch, die Schallisolierungseigenschaften weiter zu verbessern. Dabei sollen die Herstellkosten nicht oder in möglichst geringem Umfang erhöht werden.Although good sound insulation values can now be achieved with dry construction walls created using such known C profiles, there is a desire to further improve the sound insulation properties. The manufacturing costs should not be increased or as little as possible.

Aufgabe der vorliegenden Erfindung ist daher, ein C-Profil der eingangs genannten Art so weiter zu bilden, dass insbesondere bei geringen Mehrkosten die Schallisolierung verbessert wird.The object of the present invention is therefore to develop a C-profile of the type mentioned at the outset in such a way that the sound insulation is improved in particular at low additional costs.

Diese Aufgabe wird bei einem eingangs genannten C-Profil mit den Merkmalen von Anspruch 1 gelöst. Dabei ist insbesondere vorgesehen, dass die Sicken wenigstens abschnittweise derart ausgebildet sind, dass bei 0,3 mm Eindringtiefe der Sicken in eine Beplankung die Anlagefläche größer als 5% der Seitenfläche und kleiner 25% der Seitenfläche ist, dass wenigstens eine der Sicken (6) im Bereich der Anlagefläche gewölbt ist und der Radius am Scheitelpunkt der Sicke (6) zwischen 0,6 mm und 2,5 mm beträgt und dass die Höhen der Sicken zwischen 0,5 mm und 5 mm beträgt.This object is achieved in a C profile mentioned at the outset with the features of claim 1. In particular, it is provided that the beads are designed at least in sections in such a way that the beads penetrate into a planking when the depth of penetration is 0.3 mm Contact surface greater than 5% of the side surface and less than 25% of the side surface is that at least one of the beads (6) in the area Contact surface is curved and the radius at the apex of the bead (6) is between 0.6 mm and 2.5 mm and that the heights of the beads are between 0.5 mm and 5 mm.

Durch eine entsprechende Ausbildung der Sicken mit der erfindungsgemäßen Größe der Anlagefläche wird eine erhebliche Verbesserung der Schallisolierungseigenschaften erreicht. Die Angabe der Größe der Anlagefläche ist dabei für eine Eindringtiefe von 0,3 mm angegeben. Bei der Montage des erfindungsgemäßen C-Profils kommt es aufgrund der Verspannung mit der Beplankung zu einem gewissen Eindringen der Sicken in die Beplankung. Im Falle von Gipskartonplatten drücken sich die Sicken etwas in die Oberfläche der Platten ein. Die Angabe der Eindringtiefe bedeutet jedoch nicht, dass das C-Profil nur in eingebautem Zustand geschützt werden soll oder stets mit derselben Einbautiefe eingebaut werden muss. Vielmehr soll durch diese Angabe die Anlagefläche für das C-Profil eindeutig definiert werden, unabhängig von den beim späteren Einbau auftretenden Kräften und der sich daraus ergebenden Eindringtiefe im eingebauten Zustand. Die Seitenfläche ergibt sich aus dem Produkt aus Länge und Breite der Schenkelabschnitte, unabhängig von eventuell vorhandenen Ausschnitten, Bohrungen, Verformungen in den Schenkelabschnitten.A corresponding improvement in the sound insulation properties is achieved by appropriately designing the beads with the size of the contact surface according to the invention. The size of the contact surface is specified for a penetration depth of 0.3 mm. When assembling the C-profile according to the invention, there is some penetration of the beads into the planking due to the bracing with the planking. In the case of plasterboard, the beads press a little into the surface of the boards. However, the specification of the penetration depth does not mean that the C-profile should only be protected when installed or that it must always be installed with the same installation depth. Rather, this information is intended to clearly define the contact surface for the C-profile, regardless of the forces that occur during later installation and the resulting penetration depth in the installed state. The side surface results from the product of the length and width of the leg sections, regardless of any cutouts, bores, deformations in the leg sections.

Eine weitere Verbesserung wird dadurch erreicht, dass die Sicken derart ausgebildet und bemessen sind, dass bei 0,3 mm Eindringtiefe der Sicken in eine Beplankung die Anlagefläche größer als 10% der Seitenfläche und kleiner 20% der Seitenfläche ist, insbesondere größer als 12 % der Seitenfläche und kleiner als 18% der Seitenfläche.A further improvement is achieved in that the beads are designed and dimensioned in such a way that the contact surface is greater than 10% of the side surface and less than 20% of the side surface, in particular greater than 12% of the, at 0.3 mm penetration depth of the beads in a paneling Side area and less than 18% of the side area.

Besonders bewährt hat sich, wenn die Sicken derart ausgebildet und bemessen sind, dass bei 0,3 mm Eindringtiefe der Sicken in eine Beplankung die Anlagefläche größer als 13 % der Seitenfläche und kleiner 16 % der Seitenfläche ist.It has proven particularly useful if the beads are designed and dimensioned in such a way that the contact surface is greater than 13% of the side surface and less than 16% of the side surface when the beads are 0.3 mm deep into a planking.

Die Herstellung wird dadurch erleichtert, dass die Schenkelabschnitte und der Bodenabschnitt aus einem einstückigen Blechteil bestehen.Manufacturing is facilitated in that the leg sections and the bottom section consist of a one-piece sheet metal part.

Vorteilhafterweise sind die Sicken länglich ausgebildet und verlaufen in Längsrichtung des C-Profils, insbesondere über dessen gesamte Länge.The beads are advantageously elongated and run in the longitudinal direction of the C-profile, in particular over its entire length.

Eine gute Lastverteilung ergibt sich, wenn jeder Schenkelabschnitt drei bis fünf parallele Sicken, insbesondere vier parallele Sicken aufweist.A good load distribution results if each leg section has three to five parallel beads, in particular four parallel beads.

Erfindungsgemäß ist vorgesehen, dass die Höhe der Sicken zwischen 0,5 mm und 5 mm beträgt. Vorzugsweise beträgt die Höhe zwischen 1 mm und 3 mm.According to the invention, the height of the beads is between 0.5 mm and 5 mm. The height is preferably between 1 mm and 3 mm.

Erfindungsgemäß ist weiterhin vorgesehen, dass wenigstens eine der Sicken im Bereich der Anlagefläche gewölbt ist und der Radius am Scheitelpunkt der Sicke zwischen 0,6 mm und 2,5 mm beträgt. Vorzugsweise beträgt der Radius am Scheitelpunkt zwischen 0,8 mm und 1,9 mm.According to the invention, it is further provided that at least one of the beads is curved in the area of the contact surface and the radius at the apex of the bead is between 0.6 mm and 2.5 mm. The radius at the apex is preferably between 0.8 mm and 1.9 mm.

Eine weitere Verbesserung wird dadurch erreicht, dass die Sicken derart ausgebildet sind, dass die Breite der Anlagefläche im Bereich einer der Sicken bei 0,3 mm Eindringtiefe der Sicken in eine Beplankung zwischen 1 mm und 3 mm, insbesondere zwischen 1,3 und 2,2 mm beträgt.A further improvement is achieved in that the beads are designed in such a way that the width of the contact surface in the area of one of the beads with a penetration depth of 0.3 mm into a planking between 1 mm and 3 mm, in particular between 1.3 and 2, Is 2 mm.

Die Steifigkeit aber auch die Schallisolationseigenschaften des C-Profils werden dadurch weiter verbessert, dass das Blech des C-Profils in wenigstens einem Teil seiner Oberfläche eine Rändelung aufweist. Durch die Rändelung ergeben sich lokale, insbesondere punktförmige Verformungen des Bleches. Dabei kann insbesondere eine große Anzahl von Verformungen pro Flächeneinheit vorgesehen ; sein, erfindungsgemäß mehr als 5 Verformungen pro cm2 oder: insbesondere mehr als 10 Verformungen pro cm2).The rigidity but also the sound insulation properties of the C-profile are further improved in that the sheet of the C-profile has knurling in at least part of its surface. The knurling results in local, in particular punctiform, deformations of the sheet. In particular, a large number of deformations per unit area; be, according to the invention, more than 5 deformations per cm 2 or: in particular more than 10 deformations per cm 2 ).

Insbesondere kann weiterhin vorgesehen sein, dass die Sicken an ihrer Oberseite jeweils einen Vorsprung und an ihrer Unterseite einen Rücksprung bilden.In particular, it can further be provided that the beads each form a projection on their upper side and a recess on their underside.

Die Nutzbarkeit des C-Profils wird dadurch erweitert, dass die beiden. Schenkelabschnitte unterschiedlich lang sind und es dadurch ermöglichen, zwei identische C-Profile zu einem Rechteckprofil derart zusammenzufügen, dass der kürzere Schenkelabschnitt des jeweils einen C-Profils an der Innenseite des längeren Schenkelabschnitts des jeweils anderen C-Profils zu liegen kommt.The usability of the C-profile is expanded by the fact that the two. Leg sections are of different lengths and thereby make it possible to join two identical C profiles to form a rectangular profile in such a way that the shorter leg section of the one C profile comes to lie on the inside of the longer leg section of the other C profile.

Hierbei ist von Vorteil, wenn die Sicken der beiden Schenkelabschnitte derart versetzt zueinander angeordnet sind, dass beim Zusammenfügen zweier C-Profile zu einem Rechteckprofil die Vorsprünge der Sicken der kürzeren Schenkelabschnitte in den Rücksprüngen der Sicken der längeren Schenkelabschnitte zu liegen kommen. Durch den Versatz der Sicken ergibt sich dabei ein abweichender Abstand der Sicken von dem Bodenabschnitt. Der Abstand zwischen den Sicken beider Schenkelabschnitte kann jedoch gleich sein.It is advantageous here if the beads of the two leg sections are arranged offset to one another such that when two C-profiles are joined together to form a rectangular profile, the projections of the beads of the shorter leg sections come to lie in the recesses of the beads of the longer leg sections. The offset of the beads results in a different distance between the beads and the bottom section. However, the distance between the beads of both leg sections can be the same.

Insbesondere hat sich bewährt, wenn die Dicke des Bleches zwischen 0,3 mm und 3 mm beträgt, insbesondere 0,4 mm bis 0,6 mm. Weitere Ziele, Merkmale, Vorteile und Anwendungsmöglichkeiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen anhand der Zeichnung. Dabei bilden alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger sinnvoller Kombination den Gegenstand der Erfindung, innerhalb des Schutzumfangs der beigefügten Ansprüche.It has proven particularly useful if the thickness of the sheet is between 0.3 mm and 3 mm, in particular 0.4 mm to 0.6 mm.

Wie insbesondere in den Figuren 1 und 2 erkennbar, weist das C-Profil 1 jeweils einen Bodenabschnitt 3 und zwei Schenkelabschnitte 2, 2' auf. Das C-Profil 1 ist dabei länglich ausgebildet. Entsprechend haben der Bodenabschnitt 3 und die Schenkelabschnitte 2, 2'jeweils eine im Wesentlichen rechteckige Grundform. Die Schenkelabschnitte 2, 2' sind jeweils an den Längsseiten des Bodenabschnitts 3 vorgesehen und erstrecken sich im Wesentlichen rechtwinklig zu diesem in dieselbe Richtung. An ihren dem Bodenabschnitt 3 abgewandten Enden weisen die Schenkelabschnitte 2, 2' jeweils einen rechtwinklig nach innen abgewinkelten Falz 13 auf.As especially in the Figures 1 and 2 recognizable, the C-profile 1 each has a bottom section 3 and two leg sections 2, 2 '. The C-profile 1 is elongated. Correspondingly, the base section 3 and the leg sections 2, 2 ′ each have an essentially rectangular basic shape. The leg sections 2, 2 'are each provided on the longitudinal sides of the bottom section 3 and extend essentially at right angles to the latter in the same direction. At their ends facing away from the bottom section 3 the leg sections 2, 2 'each have a fold 13 which is angled inwards at right angles.

Bei den in den Figuren 1 bis 5 dargestellten Ausführungsformen ist der Bodenabschnitt 3 im Wesentlichen eben ausgebildet. Er weist jedoch zwei sich in Längsrichtung des C-Profils 1 erstreckende Nuten 4 auf.In the in the Figures 1 to 5 In the illustrated embodiments, the bottom section 3 is essentially flat. However, it has two grooves 4 extending in the longitudinal direction of the C-profile 1.

Die beiden Schenkelabschnitte 2, 2' bilden jeweils eine Seitenfläche 5 des C-Profils 1. Dabei sind in den Schenkelabschnitten 2, 2' Sicken 6 vorgesehen. Bei den in den Figuren dargestellten Ausführungsformen sind jeweils vier Sicken 6 vorgesehen, die sich in Längsrichtung des C-Profils 1 über dessen gesamte Länge erstrecken. Dabei können die Sicken 6, anders als dargestellt, auch so ausgebildet sein, dass sie sich nur über einen Teil der Länge des Schenkelabschnitts 2, 2' und/oder in eine andere als die Längsrichtung erstrecken.The two leg sections 2, 2 'each form a side surface 5 of the C-profile 1. In this case, beads 6 are provided in the leg sections 2, 2'. In the embodiments shown in the figures, four beads 6 are provided, which extend in the longitudinal direction of the C-profile 1 over its entire length. In this case, the beads 6, other than shown, can also be designed such that they extend only over part of the length of the leg section 2, 2 'and / or in a direction other than the longitudinal direction.

Das C-Profil 1 mit den Schenkelabschnitten 2, 2' und dem Bodenabschnitt 3 besteht aus einem einstückigen Blechteil . Die Schenkelabschnitte 2, 2' werden durch Kaltwalzen bzw. Biegen in die in den Figuren dargestellte Form gebracht. Auch die Sicken 6 und die Nuten 4 werden durch Kaltverformung des Stahlbleches erzeugt. Bei der in Figur 1 dargestellten Ausführungsform ist das Blech, abgesehen von den Sicken 6 und den Nuten 4, im Wesentlichen glatt ausgebildet. Bei der in Figur 2 dargestellten Ausführungsform hingegen ist eine Rändelung 7 vorgesehen. Entsprechend weist das Blech eine große Anzahl von lokalen, insbesondere punktförmigen Verformungen auf, wie dies in Figur 2 gut erkennbar ist. Dabei können mehr als fünf Verformungen pro cm2 und insbesondere mehr als zehn Verformungen pro cm2 vorgesehen werden.The C-profile 1 with the leg sections 2, 2 'and the bottom section 3 consists of a one-piece sheet metal part. The leg sections 2, 2 'are brought into the shape shown in the figures by cold rolling or bending. The beads 6 and the grooves 4 are also produced by cold forming the steel sheet. At the in Figure 1 In the illustrated embodiment, the sheet metal, apart from the beads 6 and the grooves 4, is essentially smooth. At the in Figure 2 illustrated embodiment, however, a knurling 7 is provided. Accordingly, the sheet has a large number of local, in particular punctiform, deformations, as shown in FIG Figure 2 is clearly recognizable. In this case, more than five deformations per cm 2 and in particular more than ten deformations per cm 2 can be provided.

Figuren 3 und 4 zeigen, wie das C-Profil 1 zum Aufbau einer abschnittsweise dargestellten Trennwand 8 eingesetzt werden kann. Hierbei ist das C-Profil 1 mit seinem Bodenabschnitt 3 quer zur Trennwand 8 ausgerichtet, wobei es mit den Schenkelabschnitten 2, 2' an der Innenseite der Beplankung zur Anlage kommt. Als Beplankung eignen sich insbesondere die dargestellten Gipskartonplatten 9, 9', 9", welche über Verbindungsmittel 10, die vorliegend als Schrauben ausgebildet sind, mit den Schenkelabschnitten 2, 2' verbunden sind. In dem unteren Abschnitt von Figur 3 ist erkennbar, dass je zwei Gipskartonplatten 9', 9" aneinander stoßen, wobei die Stoßstelle mit Spachtelmasse 15 geschlossen ist. In dem Inneren der Trennwand 8 ist zudem ein Dämmstoff 11 vorgesehen, zur Isolierung gegen Schall und/oder Wärme. Figures 3 and 4 show how the C-profile 1 can be used to build a partition 8 shown in sections. Here, the C-profile 1 is aligned with its bottom section 3 transversely to the partition 8, with the leg sections 2, 2 'coming to rest on the inside of the cladding. The plasterboard panels 9, 9 ', 9 "shown are particularly suitable as cladding, which are connected to the leg sections 2, 2' via connecting means 10, which are designed here as screws. In the lower section of Figure 3 it can be seen that two plasterboard plates 9 ', 9 "abut each other, the joint being closed with filler 15. In the interior of the partition 8 there is also an insulating material 11 for insulation against sound and / or heat.

Da die Schenkelabschnitte 2, 2' nur mit den Sicken 6 an den Gipskartonplatten 9, 9', 9" anliegen, wird die Anlagefläche durch die am weitesten vorstehenden Bereiche der Sicken 6 gebildet. Aufgrund der länglichen Ausbildung der Sicken 6 ergeben sich daher bei der dargestellten Ausführungsform im Bereich jeder Sicke 6 streifenförmige Anlageflächenabschnitte 12. Die Fläche eines Anlageflächenabschnittes 12 ergibt sich daher aus der Breite R des Anlageflächenabschnittes 12 und dessen Länge. Die gesamte Anlagefläche ergibt sich dabei durch Addition der einzelnen Anlageflächenabschnitte 12. Dies sind bei den dargestellten Ausführungsformen für jede Seitenfläche 5, entsprechend den vier Sicken 6, vier Anlageflächenabschnitte 12.Since the leg sections 2, 2 'rest only on the plasterboard panels 9, 9', 9 "with the beads 6, the contact surface is formed by the most protruding areas of the beads 6. Because of the elongated configuration of the beads 6, Embodiment shown in the area of each bead 6 strip-shaped contact surface sections 12. The area of a contact surface section 12 therefore results from the width R of the contact surface section 12 and its length. The total contact surface is obtained by adding the individual contact surface sections 12. These are in the illustrated embodiments for each side surface 5, corresponding to the four beads 6, four contact surface sections 12.

Dabei hat sich gezeigt, dass eine gute Schallisolation erreicht wird, wenn die Anlagefläche zwischen 5 % und 25 % und insbesondere zwischen 10 % und 20 % der Seitenfläche 5 beträgt. Die Seitenfläche 5 bemisst sich dabei nach dem Produkt aus der Länge der L und der Breite B der Schenkelabschnitte 2 bzw. 2', unabhängig von evtl. vorhandenen Ausschnitten, Bohrungen usw. in den Schenkelabschnitten 2 (vgl. Figur 1). Da die Anlagefläche von der Eindringtiefe E abhängen kann, wird die Anlagefläche bei angenommenen 0,3 mm Eindringtiefe E der Sicken 6 in die Beplankung ermittelt. Besonders gute Ergebnisse werden erzielt, wenn die Anlagefläche zwischen 12 und 18 %, vorzugsweise zwischen 13 % und 16 % der Seitenfläche beträgt.It has been shown that good sound insulation is achieved if the contact surface is between 5% and 25% and in particular between 10% and 20% of the side surface 5. The side surface 5 is measured according to the product of the length L and the width B of the leg sections 2 and 2 ', regardless of any cutouts, bores, etc. in the Leg sections 2 (cf. Figure 1 ). Since the contact surface can depend on the penetration depth E, the contact surface is determined with an assumed 0.3 mm penetration depth E of the beads 6 in the planking. Particularly good results are achieved if the contact surface is between 12 and 18%, preferably between 13% and 16% of the side surface.

Die Höhe der Sicken 6 beträgt zwischen 0,5 und 5 mm insbesondere zwischen 1 mm und 3 mm. Bei den dargestellten Ausführungsformen ist die Höhe der Sicken eines C-Profils jeweils identisch.The height of the beads 6 is between 0.5 and 5 mm, in particular between 1 mm and 3 mm. In the illustrated embodiments, the height of the beads of a C-profile is identical in each case.

Die Sicken 6 sind im Bereich der Anlagefläche gewölbt, wie dies gut in Figur 4 erkennbar ist. Der Radius am Scheitelpunkt der Sicken beträgt zwischen 0,6 mm und 2,5mm, vorzugsweise zwischen 0,8 mm und 1,9 mm. Weiterhin sind die Sicken 6 derart ausgebildet, dass die Breite R der Anlageflächenabschnitte 12 bei 0,3 mm Eindringtiefe E der Sicken 6 in eine Beplankung jeweils zwischen 1 mm und 3 mm, insbesondere zwischen 1,3 und 2,1 mm beträgt.The beads 6 are arched in the area of the contact surface, as is well shown in Figure 4 is recognizable. The radius at the apex of the beads is between 0.6 mm and 2.5 mm, preferably between 0.8 mm and 1.9 mm. Furthermore, the beads 6 are designed such that the width R of the contact surface sections 12 with a penetration depth E of 0.3 mm of the beads 6 into a cladding is in each case between 1 mm and 3 mm, in particular between 1.3 and 2.1 mm.

Die C-Profile 1 bestehen aus Stahlblech mit einer Dicke zwischen 0,3 mm und 3 mm, insbesondere zwischen 0,4 mm und 0,6 mm. Der E-Modul des Bleches liegt zwischen 196 kN/mm2 und 216 kN/mm2. Die Zugfestigkeit des Bleches liegt zwischen 270 MPa und 500 MPa.The C-profiles 1 consist of sheet steel with a thickness between 0.3 mm and 3 mm, in particular between 0.4 mm and 0.6 mm. The sheet's modulus of elasticity is between 196 kN / mm 2 and 216 kN / mm 2 . The tensile strength of the sheet is between 270 MPa and 500 MPa.

In Figur 5 ist erkennbar, wie zwei identische C-Profile 1 zu einem Rechteckprofil zusammengesetzt werden können. Um dies zu erleichtern, sind die beiden Schenkelabschnitte 2, 2' eines C-Profils 1 unterschiedlich lang ausgebildet, wodurch die Möglichkeit gegeben ist, die beiden C-Profile 1 auf einfache Weise miteinander zu verschachteln. Dabei wird der kürzere der beiden Schenkelabschnitte 2 eines C-Profils 1 an der Innenseite des längeren der beiden Schenkelabschnitte 2' des anderen C-Profils 1 angeordnet. Die Länge des kürzeren Schenkelabschnitts 2 ist dabei so bemessen, dass dieser in dem sich zwischen dem Falz 13 und der Innenseite 14 des Bodenabschnitts 3 ergebenden Raum aufgenommen werden kann. Die Innenseite 14 des Bodenabschnitts 3 ist die den Schenkelabschnitten 2, 2' zugewandte Seite des Bodenabschnitts 3. Die Längendifferenz zwischen den beiden Schenkelabschnitten 2 und 2' beträgt dabei insbesondere das zweifache der Blechdicke oder mehr. Vorzugsweise liegt die Längendifferenz zwischen dem zwei- und vierfachen der Blechdicke.In Figure 5 it can be seen how two identical C-profiles 1 can be put together to form a rectangular profile. To facilitate this, the two leg sections 2, 2 'of a C-profile 1 are of different lengths, which makes it possible to easily nest the two C-profiles 1 with one another. The shorter of the two leg sections 2 of a C-profile 1 is arranged on the inside of the longer of the two leg sections 2 'of the other C-profile 1. The length of the shorter one Leg section 2 is dimensioned such that it can be accommodated in the space that results between the fold 13 and the inside 14 of the bottom section 3. The inside 14 of the bottom section 3 is the side of the bottom section 3 facing the leg sections 2, 2 '. The length difference between the two leg sections 2 and 2' is in particular twice the sheet thickness or more. The length difference is preferably between two and four times the sheet thickness.

Weiterhin sind die Sicken 6 der beiden Schenkelabschnitte 2, 2' derart versetzt zueinander angeordnet, dass beim Zusammenfügen der zwei C-Profile 1 zu dem in Figur 5 dargestellten Rechteckprofil die Sicken 6 des kürzeren Schenkelabschnitts 2 mit ihren Vorsprüngen in den Rücksprüngen der Sicken 6 des längeren Schenkelabschnitts 2' zu liegen kommen. Dabei ist der Abstand der Sicken 6 des kürzeren Schenkelabschnitts 2 und der Abstand der Sicken 6 des längeren Schenkelabschnitts 2' zu dem Bodenabschnitt 3 verschieden.Furthermore, the beads 6 of the two leg sections 2, 2 'are arranged offset to one another such that when the two C-profiles 1 are joined to form the Figure 5 shown rectangular profile, the beads 6 of the shorter leg section 2 come to rest with their projections in the recesses of the beads 6 of the longer leg section 2 '. The distance between the beads 6 of the shorter leg section 2 and the distance of the beads 6 of the longer leg section 2 'from the bottom section 3 are different.

Figur 6 zeigt eine weitere Ausführungsform eines erfindungsgemäßen C-Profils 1, eingebaut in eine Trennwand 8. Aufbau des C-Profils 1 und der Trennwand 8 stimmen dabei weitgehend mit der in den Figuren 3 und 4 gezeigten Ausführungsform überein. Auf die diesbezügliche Beschreibung, welche entsprechend für Figur 6 gilt, wird Bezug genommen. Teile gleicher Funktion sind dabei mit denselben Bezugszeichen versehen. Bei der in Figur 6 dargestellten Ausführungsform ist jedoch in dem Bodenabschnitt 3 nur eine längs des C-Profils verlaufende Nut 4 vorgesehen, welche breiter ausgebildet ist als die in Figur 3 dargestellten Nuten. Figure 6 shows a further embodiment of a C-profile 1 according to the invention, installed in a partition 8. The structure of the C-profile 1 and the partition 8 are largely the same as in FIGS Figures 3 and 4 shown embodiment match. On the relevant description, which accordingly for Figure 6 applies, reference is made. Parts with the same function are provided with the same reference symbols. At the in Figure 6 In the illustrated embodiment, however, only a groove 4 running along the C-profile is provided in the bottom section 3, which is wider than that in FIG Figure 3 shown grooves.
