Description

Profil aus Blech für den TrockenbauSheet metal profile for drywall
Die vorliegende Erfindung betrifft ein Profil aus Blech für den Trockenbau mit zwei Schenkelabschnitten und einem die Schenkelabschnitte verbindenden Bodenabschnitt, sowie mit wenigstens einem an einem der Schenkelabschnitte angeordneten Verstärkungsstreifen.The present invention relates to a sheet metal profile for drywall construction having two leg sections and a bottom section connecting the leg sections and at least one reinforcing strip arranged on one of the leg sections.
Derartige Profile aus Blech werden im Trockenbau in unterschiedlichen Ausführungen eingesetzt. Eine bekannte Ausführung eines solchen Profils wird als C-Profϊl bezeichnet und weist zwei Schenkelabschnitte und einen die Schenkelabschnitte verbindenden Bodenabschnitt auf, wobei an den Schenkelabschnitten jeweils ein sich in Längsrichtung des Profils erstreckender umgebogener Tragrand vorgesehen ist.Such profiles made of sheet metal are used in dry construction in different versions. A known embodiment of such a profile is referred to as C-Profϊl and has two leg portions and a bottom portion connecting the leg portions, wherein on the leg portions each one extending in the longitudinal direction of the profile bent support edge is provided.
In der DIN 18 182 (Teil 1) in der Fassung vom Januar 1987 ist beschrieben, bei einem solchen C-Profil den Tragrand mit einer doppelten Umbördelung zu versehen, wobei sich dieser doppelte Bereich über einen Teil der Breite des Tragrandes erstreckt. Weiterhin ist dem Fachmann bekannt, dass ein C-Profϊl durch die Verwendung eines Bleches mit höherer Materialstärke stabiler gestaltet werden kann.In the DIN 18 182 (Part 1) in the version of January 1987 is described to be provided in such a C-profile, the supporting edge with a double bead, this double area extends over part of the width of the supporting edge. Furthermore, it is known to those skilled in the art that a C-Profϊl can be made more stable by the use of a sheet with higher material thickness.
Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Profil derart weiterzuentwickeln, dass dieses bei gegebener Materialstärke besonders stabil ist.Object of the present invention is to develop a generic profile such that it is particularly stable for a given material thickness.
Diese Aufgabe wird gelöst durch ein Profil aus Blech für den Trockenbau mit zwei Schenkelabschnitten und einem dieThis object is achieved by a profile made of sheet metal for drywall construction with two leg sections and one
Schenkelabschnitte verbindenden Bodenabschnitt, sowie mit wenigstens einem an einem der Schenkelabschnitte angeordneten Verstärkungsstreifen, wobei Mittel zum Befestigen des Verstärkungsstreifens an dem Schenkelabschnitt vorgesehen sind.Leg portions connecting bottom portion, and with at least one arranged on one of the leg portions reinforcing strip, wherein means are provided for attaching the reinforcing strip to the leg portion.
Die erfindungsgemäße Gestaltung ermöglicht eine erhebliche Steigerung der Stabilität des Profils. Aufgrund der Mittel zum Befestigen des Verstärkungsstreifens kann eine effektive Krafteinleitung und damit eine gute Materialausnutzung erreicht werden. So wird es erstmals möglich, für das Profil ein dünneres Blech einzusetzen und dennoch Stabilitätswerte für das Profil zu erhalten, welche zuvor nur mit einem erheblich dickeren Blech zu erzielen waren. Hieraus resultiert ein erhebliches Einsparpotential, da der Materialeinsatz insgesamt wesentlich reduziert werden kann. Zwar wird aufgrund des Verstärkungsstreifens eine etwas größere Fläche an Material benötigt. Dies wird jedoch aufgrund der Verwendung eines dünneren Bleches mehr als aufgewogen, so dass insgesamt der Materialverbrauch und damit die Herstellungskosten gesenkt werden können. Ein weiterer Vorteil ist, dass auch die Handhabung und der Transport aufgrund des erzielbaren geringeren Gewichtes erleichtert werden. Eine weitere Verbesserung der Stabilität wird dadurch erreicht, dass die Mittel zum Befestigen des Verstärkungsstreifens an dem Schenkelabschnitt plastische Materialverformungen des Verstärkungsstreifens und/ oder des Schenkelabschnitts aufweisen. Dabei kann vorzugsweise eine Vielzahl von lokalen plastischen Materialverformungen vorgesehen sein.The design according to the invention enables a considerable increase in the stability of the profile. Due to the means for securing the reinforcing strip, an effective introduction of force and thus a good material utilization can be achieved. This makes it possible for the first time to use a thinner sheet metal for the profile and still obtain stability values for the profile, which previously could only be achieved with a considerably thicker sheet metal. This results in a considerable potential savings, since the use of materials can be significantly reduced overall. Although due to the reinforcing strip a slightly larger area of material is needed. However, this is more than offset by the use of a thinner sheet, so that overall the material consumption and thus the production costs can be reduced. Another advantage is that the handling and transport are facilitated due to the achievable lower weight. A further improvement of the stability is achieved in that the means for attaching the reinforcing strip to the leg section have plastic material deformations of the reinforcing strip and / or the leg section. In this case, a plurality of local plastic material deformations may preferably be provided.
Weiterhin hat sich als vorteilhaft herausgestellt, wenn die plastischen Materialverformungen eine längliche Form haben und sich insbesondere in Längsrichtung des Verstärkungsstreifens erstrecken.Furthermore, it has proven to be advantageous if the plastic material deformations have an elongated shape and in particular extend in the longitudinal direction of the reinforcing strip.
Von Vorteil können die plastischen Materialverformungen durch Umformfügen von Schenkelabschnitt, z.B. einem hieran ausgebildeten Tragrand, und Verstärkungsstreifen, insbesondere durch Clinchen erzeugt sein.Advantageously, the plastic material deformations can be achieved by forming leg section, e.g. a carrying edge formed thereon, and reinforcing strips, in particular by clinching.
Wenn die Mittel zum Befestigen des Verstärkungsstreifens an dem Schenkelabschnitt ein Klebemittel aufweisen, kann die Stabilität des Profils weiter verbessert werden.When the means for attaching the reinforcing strip to the leg portion comprise an adhesive, the stability of the profile can be further improved.
Die Herstellung des Profils ist dann besonders einfach, wenn der Verstärkungsstreifen ein zurückgebogener Teil des Schenkelabschnitts ist, der durch die Mittel zum Befestigen des Verstärkungsstreifens fixiert wird.The manufacture of the profile is particularly simple if the reinforcing strip is a bent-back part of the leg section which is fixed by the means for fastening the reinforcing strip.
Alternativ kann der Verstärkungsstreifen ein separates Element, insbesondere ein Blechstreifen sein. In diesem Fall kann ein Umformschritt des Bleches entfallen, da der Verstärkungsstreifen nicht zurückgebogen werden muss. Der Verstärkungsstreifen kann stattdessen bei der Herstellung separat zugeführt und durch die Mittel zum Befestigen mit dem Schenkelabschnitt, z.B. dessen Tragrand verbunden werden. Hierbei können für den Verstärkungsstreifen auch anfallende Spaltreste bzw. Besäumungsstreifen oder andere Restmaterialien verwendet werden.Alternatively, the reinforcing strip may be a separate element, in particular a sheet metal strip. In this case, a forming step of the sheet can be omitted since the reinforcing strip does not have to be bent back. Instead, the reinforcing strip may be separately fed during manufacture and connected by the means for attachment to the leg portion, eg its supporting edge. Here can also for the reinforcing strip accumulating cleavage residues or trimming strips or other residual materials are used.
Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass wenigstens einer der Schenkelabschnitte einen in Längsrichtung des Profils verlaufenden umgebogenen Tragrand aufweist und dass der Verstärkungsstreifen an dem umgebogenen Tragrand angeordnet ist.According to a particularly advantageous embodiment of the invention, it is provided that at least one of the leg sections has a bent-over support edge extending in the longitudinal direction of the profile and that the reinforcing strip is arranged on the bent-over support edge.
Nach der Erfindung kann weiter vorgesehen sein, dass sich der Verstärkungsstreifen entlang des Tragrandes, insbesondere über dessen gesamte Länge erstreckt und/ oder auf der dem Bodenabschnitt zugewandten und/ oder abgewandten Seite des Tragrandes angeordnet ist. Bei der Anordnung auf der dem Bodenabschnitt zugewandten Seite ergibt sich eine besonders hohe Stabilität.According to the invention it can further be provided that the reinforcing strip extends along the supporting edge, in particular over its entire length, and / or is arranged on the side of the supporting edge facing and / or facing away from the bottom section. In the arrangement on the bottom portion facing side results in a particularly high stability.
Weiterhin hat sich bewährt, wenn der Tragrand in Querrichtung des Tragrandes eine Wölbung aufweist. Diese kann derart ausgebildet sein, dass der Tragrand auf der dem Bodenabschnitt abgewandten Seite konvex und/ oder auf der dem Bodenabschnitt zugewandten Seite konkav ausgebildet ist.Furthermore, it has proven useful if the supporting edge in the transverse direction of the supporting edge has a curvature. This can be designed such that the supporting edge on the side facing away from the bottom portion is convex and / or concave on the side facing the bottom portion.
Gemäß einer besonders vorteilhaften Gestaltung ist vorgesehen, dass sich der Verstärkungsstreifen über die gesamte Breite des umgebogenen Tragrands erstreckt.According to a particularly advantageous embodiment, it is provided that the reinforcing strip extends over the entire width of the folded support edge.
Erfindungsgemäß kann zudem das Profil als C-Profil oder U-Profil ausgebildet sein.According to the invention, the profile can also be designed as a C-profile or U-profile.

Die Figuren 2 bis 5 verdeutlichen, dass Mittel 12 zum Befestigen des Verstärkungsstreifens 5 an dem Schenkelabschnitt 2 vorgesehen sind. Diese sind bei den dargestellten Ausführungsformen als den Tragrand 4 und den Verstärkungsstreifen 5 verbindende plastische Materialverformungen 11 ausgebildet und befestigen den Verstärkungsstreifen 5 an dem Tragrand 4.Figures 2 to 5 illustrate that means 12 are provided for attaching the reinforcing strip 5 to the leg portion 2. These are formed in the illustrated embodiments as the supporting edge 4 and the reinforcing strip 5 connecting plastic material deformations 11 and fasten the reinforcing strip 5 on the support edge. 4
Dabei sind eine Vielzahl von lokalen, örtlich begrenzten Materialverformungen 11 vorgesehen, welche über den Tragrand 4 bzw. den Verstärkungsstreifen 5 verteilt angeordnet sind. Bei den dargestellten Ausführungsformen haben die Materialverformungen 11 jeweils eine längliche Form und erstrecken sich in Längsrichtung des Verstärkungsstreifens 5. Diese Ausgestaltung eignet sich besonders im Rahmen der Erfindung. Es können jedoch auch Materialverformungen in anderen, nicht dargestellten Formen verwendet werden. Eine besonders hohe Stabilität wird dann erreicht, wenn das Material von Tragrand 4 und Verstärkungsstreifen 5 aufgrund der plastischen Materialverformungen 11 ineinanderfließt.In this case, a plurality of local, localized material deformations 11 are provided, which are distributed over the supporting edge 4 and the reinforcing strip 5. In the illustrated embodiments, the material deformations 11 each have an elongate shape and extend in the longitudinal direction of the reinforcing strip 5. This embodiment is particularly suitable in the context of the invention. However, material deformations in other forms, not shown, may also be used. A particularly high stability is achieved when the material of support edge 4 and reinforcing strip 5 flows into each other due to the plastic material deformations 11.
Die Materialverformungen 11 können durch Umformfügen von Tragrand 4 und Verstärkungsstreifen 5 erzeugt sein. Insbesondere das als Clinchen bezeichnete Verfahren kann hierbei Verwendung finden.The material deformations 11 can be produced by forming joining of supporting edge 4 and reinforcing strip 5. In particular, the method referred to as clinching can be used here.
Auch bei den in den Figuren 6 und 7 dargestellten Ausführungsformen, welche das Profil 1 lediglich von der Seite zeigen, sind gleichfalls Materialverformungen der in den Figuren 2 bis 5 gezeigten Art vorgesehen. Alternativ oder zusätzlich zu den Materialverformungen 11 können die Mittel 12 zum Befestigen des Verstärkungsstreifens 5 an dem Schenkelabschnitt 2 einen den Verstärkungsstreifen 5 mit dem Schenkelabschnitt 2 bzw. dessen Tragrand 4 verbindenden Klebstoff umfassen. Dies führt zu einer besonders hohen Belastbarkeit, insbesondere wenn Materialverformungen 11 und Klebstoff gleichzeitig vorgesehen werden.Also in the embodiments shown in Figures 6 and 7, which show the profile 1 only from the side, material deformations of the type shown in Figures 2 to 5 are also provided. Alternatively or in addition to the material deformations 11, the means 12 for attaching the reinforcing strip 5 to the leg portion 2 may comprise an adhesive connecting the reinforcing strip 5 to the leg portion 2 and its supporting edge 4, respectively. This leads to a particularly high load capacity, in particular if material deformations 11 and adhesive are provided simultaneously.
Das als C-Profil ausgebildete Profil 1 besteht aus gebogenem, insbesondere verzinktem Stahlblech. Die Materialstärke des Bleches und des Verstärkungsstreifens beträgt vorteilhafterweise zwischen 0,2 und 2,0 mm, insbesondere zwischen 0,3 und 1,0 mm und vorzugsweise 0,4mm. Trained as a C-profile 1 consists of bent, in particular galvanized sheet steel. The material thickness of the sheet and the reinforcing strip is advantageously between 0.2 and 2.0 mm, in particular between 0.3 and 1.0 mm and preferably 0.4 mm.
