Abstract

In order to reinforce sheet-metal profiles, use is made of double beads (4), which each comprise two parallel beads (5, 6). The two beads (5, 6) are deformed from the plane of the sheet metal in opposite directions. The two beads (5, 6) merge directly one into the other at a transition region (7) which rises from one bead (5) to the other bead (6). The double beads (4), which are configured, for example, in the form of an S in cross-section, may be arranged as longitudinal beads and/or transverse beads. They provide considerable reinforcement for the sheet metal profile. <IMAGE>

Description

Die Erfindung betrifft ein Blechprofilteil mit mindestens einer Sicke. Sicken werden in vielfältiger Form bei Blechprofilteilen zur Versteifung eingesetzt. Sie erhöhen die Formsteifigkeit der Blechprofilteile und ermöglichen daher die Verwendung von verhältnismäßig dünnem Blech, ohne daß eine unzulässige Verringerung der Formsteifigkeit des Blechprofilteils eintritt.The invention relates to a sheet metal profile part with at least one bead. Beads are used in a variety of forms for sheet metal profile parts for stiffening. They increase the stiffness of the sheet metal profile parts and therefore allow the use of relatively thin sheet metal without an inadmissible reduction in the stiffness of the sheet metal profile part.

Sicken werden als gerade oder gekrümmte Rinnen in im wesentlichen ebene Blechflächen gepreßt oder gewalzt. Diese Umformung geschieht ohne wesentliche Änderung der Blechdicke. Die so geformten Sicken sind jeweils aus einer Blechseite herausgewölbt.Beading is pressed or rolled as straight or curved channels in essentially flat sheet metal surfaces. This forming takes place without a significant change in the sheet thickness. The beads formed in this way are each arched out of a sheet metal side.

Es ist auch bekannt, bei Blechprofilteilen mehrere parallele oder nicht-parallele Sicken vorzusehen. Die damit erzielte Versteifungswirkung hängt von der Querschnittsgestalt der einzelnen Sicken und insbesondere von der Höhe der Sicke ab, d.h. von dem Maß, um das die Sicke aus der Blechebene herausgewölbt ist. Mit zunehmender Höhe der Sicke ist jedoch nur noch eine geringere Zunahme der Versteifungswirkung zu erzielen. Außerdem haben verhältnismäßig hohe Sicken den Nachteil, daß das benachbarte Blechmaterial in die Sicke hineingezogen wird, weil der zur Erzeugung der Sicke durchgeführte Umformvorgang ein Tiefziehvorgang ist. Hinzu kommt noch, daß zu hohe Sicken bei der Verbindung des Blechprofilteils mit anderen Bauteilen stören können. Deshalb findet die zu erzielende Versteifungswirkung in den meisten Fällen ihre Grenze darin, daß die Höhe der Sicke aus den vorstehend genannten Gründen beschränkt ist.It is also known to provide several parallel or non-parallel beads in sheet metal profile parts. The resulting stiffening effect depends on the cross-sectional shape of the individual beads and in particular on the height of the bead, ie on the amount by which the bead is curved out of the plane of the sheet. With increasing height of the bead, however, there is only a slight increase in the stiffening effect. In addition, relatively high beads have the disadvantage that the adjacent sheet material is drawn into the bead, because the forming process carried out to produce the bead is a deep-drawing process. In addition comes that too high beads can interfere with the connection of the sheet metal profile part with other components. Therefore, the stiffening effect to be achieved in most cases is limited by the fact that the height of the bead is limited for the reasons mentioned above.

Aufgabe der Erfindung ist es daher, ein Blechprofilteil der eingangs genannten Gattung so auszubilden, daß durch die Verwendung von Sicken eine erhöhte Versteifungswirkung gegenüber herkömmlichen Sicken erzielt wird, ohne daß die genannten Nachteile eintreten.The object of the invention is therefore to design a sheet-metal profile part of the type mentioned at the outset in such a way that an increased stiffening effect compared to conventional beads is achieved by using beads, without the disadvantages mentioned occurring.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwei jeweils eine Doppelsicke bildende parallellaufende Sicken in entgegensetzten Richtungen aus der Blechebene verformt sind und daß die beiden Sicken in einem von der einen Sicke zur anderen Sicke ansteigenden Übergangsbereich unmittelbar ineinander übergehen.This object is achieved in that two parallel beads forming a double bead are deformed in opposite directions from the plane of the sheet and that the two beads merge directly into one another in a transition area rising from one bead to the other bead.

Diese Doppelsicken ergeben bei verhältnismäßig geringer Sickenhöhe eine wesentlich größere Versteifungswirkung als zwei im Abstand nebeneinander ausgeführte, gleich große Sicken. Es ist zu vermuten, daß der unmittelbare Übergang zwischen den beiden einzelnen Sicken, die zusammen die Doppelsicke bilden, d.h. die Vermeidung eines zwischen den beiden Sicken liegenden, in der Blechebene verlaufenden Blechstreifens, wesentlich zu der in überraschender Weise auftretenden erhöhten Versteifungswirkung beiträgt.With a relatively low bead height, these double beads result in a substantially greater stiffening effect than two beads of equal size which are spaced apart from one another. It can be assumed that the immediate transition between the two individual beads, which together form the double bead, i.e. the avoidance of a sheet metal strip lying between the two beads and extending in the sheet metal plane makes a significant contribution to the increased stiffening effect which occurs in a surprising manner.

Da die beiden Einzelsicken mit verhältnismäßig geringer Höhe ausgeführt sind, wird auch das benachbarte Blechmaterial beim Umformvorgang nicht oder nur sehr wenig in Querrichtung in den Sickenbereich hineingezogen, so daß störende Verformungen des Blechprofilteils vermieden werden.Since the two individual beads are designed with a relatively low height, the adjacent sheet metal material is not or only very little drawn into the bead area in the transverse direction during the forming process, so that disruptive deformations of the sheet metal profile part are avoided.

Vorzugsweise verläuft die Doppelsicke in Längsrichtung eines länglichen Blechprofilteils in einem flächigen Profilbereich. Im Vergleich zu üblichen Randprofilierungen von länglichen Blechprofilteilen ergibt sich mit den erfindungsgemäßen Doppelsicken eine besonders gute Versteifungswirkung für das Blechprofilteil, wenn die Doppelsicke in einem flächigen Profilbereich verläuft, das heißt wenn sich beiderseits der Doppelsicke ebene Blechflächen anschließen, beispielsweise die Stegfläche eines U- oder C-Profils. Von besonderer Bedeutung ist hierbei auch, daß die Doppelsicken in Profillängsrichtung verlaufen, weil dadurch - bei einfacher Herstellung - gerade die typischen Eigenschaften eines länglichen Blechprofilteils (Schiene) wesentlich verbessert werden, wie Biegefestigkeit und Knickfestigkeit.The double bead preferably runs in the longitudinal direction of an elongated sheet-metal profile part in a flat profile area. Compared to the usual edge profiles of elongated sheet metal profile parts, the double beads according to the invention provide a particularly good stiffening effect for the sheet metal profile part if the double bead runs in a flat profile area, that is, if flat sheet metal surfaces are connected on both sides of the double bead, for example the web surface of a U or C Profiles. It is also particularly important here that the double beads run in the longitudinal direction of the profile, because this - with simple manufacture - improves the typical properties of an elongated sheet profile part (rail), such as bending strength and kink resistance.

Gemäß einer besonders bevorzugten Ausführungsform ist vorgesehen, daß die Doppelsicke im Querschnitt annähernd S-förmig geformt ist. Dabei werden scharfe Kanten oder kleine Krümmungsradien vermieden.According to a particularly preferred embodiment, it is provided that the double bead has an approximately S-shaped cross section. This avoids sharp edges or small radii of curvature.

Stattdessen kann aber auch vorgesehen werden, daß die Doppelsicke im Querschnitt annähernd Z-förmig geformt ist. Dadurch ergibt sich eine besonders gute Versteifungswirkung.Instead, however, it can also be provided that the double bead is approximately Z-shaped in cross section. This results in a particularly good stiffening effect.

Die in Fig. 1 als Beispiel eines Blechprofilteils dargestellte C-Schiene weist eine Stegfläche 1, davon abgewinkelte Seitenflächen 2 und wiederum davon nach innen abgewinkelte Flanschflächen 3 auf. Innerhalb der Stegfläche 1 sind im Abstand und parallel zueinander zwei Doppelsicken 4 angeordnet. Innerhalb der beiden Seitenflächen 2 ist jeweils eine längsverlaufende Doppelsicke 4 angeordnet. Beiderseits der Doppelsicken 4 liegen flächige Profilbereiche der Stegfläche 1 bzw. der Seitenflächen 2.The C-rail shown in FIG. 1 as an example of a sheet-metal profile part has a web surface 1, side surfaces 2 angled therefrom and in turn flange surfaces 3 angled inward thereof. Within the web surface 1 are two at a distance and parallel to each other Double beads 4 arranged. A longitudinal double bead 4 is arranged within each of the two side surfaces 2. Flat profile areas of the web surface 1 and the side surfaces 2 are located on both sides of the double beads 4.

Wie in Fig. 2 vergrößert im Querschnitt dargestellt ist, weist jede Doppelsicke 4 zwei prallellaufende Sicken 5 auf, die in entgegengesetzten Richtungen aus der Blechebene der Stegfläche 1 (und in entsprechender Weise aus der Stegfläche der Seitenflächen 2) verformt sind. Die beiden einzelnen Sicken 5 gehen in einem Übergangsbereich 7 ineinander über, der kontinuierlich von der einen Sicke 5 zur anderen Sicke 6 ansteigt. Im Übergangsbereich 7 gibt es daher keinen Blechabschnitt, der in der Blechebene der Stegfläche 1 verlaufen wurde. der Übergangsbereich 7 verläuft vielmehr kontinuierlich in einem ansteigenden Winkel zur Blechebene.As shown in FIG. 2, enlarged in cross section, each double bead 4 has two impact beads 5, which are deformed in opposite directions from the sheet plane of the web surface 1 (and in a corresponding manner from the web surface of the side surfaces 2). The two individual beads 5 merge into one another in a transition region 7 which rises continuously from one bead 5 to the other bead 6. In the transition area 7 there is therefore no sheet metal section that has run in the sheet metal plane of the web surface 1. rather, the transition region 7 runs continuously at an increasing angle to the sheet metal plane.

Die in Fig. 2 dargestellte und beim Blechprofilteil nach Fig. 1 verwendete Doppelsicke 4 ist mit verhältnismäßig großen Krümmungsradien ausgeführt und daher im Querschnitt annähernd S-förmig geformt.The double bead 4 shown in FIG. 2 and used in the sheet metal profile part according to FIG. 1 is designed with relatively large radii of curvature and is therefore approximately S-shaped in cross section.

Abweichend hiervon sind die Doppelsicken 4', die bei der C-Profilschiene nach Fig. 3 verwendet werden und im vergrößerten Querschnitt in Fig. 4 dargestellt sind, im Querschnitt Z-förmig geformt. Jede der beiden einzelnen Sicken 5' und 6', die die Doppelsicke 4' bilden, bestehen aus einem angenähert rechtwinklig aus der umgebenden Blechfläche, beispielsweise der Stegfläche 1 abgewinkelten Sickenstreifen 5a' bzw. 6a' und einem sich dazwischen annähernd geradlinig erstreckenden, ebenen Übergangsbereich 7', der wiederum in einem Winkel zur Ebene der umgebenden Fläche 1 ansteigend verläuft. Die Krümmungsradien an den Übergängen sind verhältnismäßig klein ausgeführt.Deviating from this, the double beads 4 ', which are used in the C-profile rail according to FIG. 3 and are shown in an enlarged cross section in FIG. 4, are shaped in a Z-shaped cross section. Each of the two individual beads 5 'and 6', which form the double bead 4 ', consist of a bead strip 5a' or 6a 'which is angled approximately at right angles from the surrounding sheet metal surface, for example the web surface 1, and a flat transition region which extends approximately rectilinearly therebetween 7 ', which in turn extends at an angle to the plane of the surrounding surface 1. The radii of curvature at the transitions are made relatively small.

Fig. 5 zeigt ein Ausführungsbeispiel einer U-Profilschiene, bei der sowohl in der Stegfläche 1 als auch in den Seitenflächen 2 jeweils zwei längsverlaufende Doppelsicken 4' der in Fig. 4 gezeigten Querschnittsgestaltung vorgesehen sind.FIG. 5 shows an exemplary embodiment of a U-shaped rail, in which two longitudinal beads 4 ′ of the cross-sectional configuration shown in FIG. 4 are provided in the web surface 1 as well as in the side surfaces 2.

Fig. 6 zeigt ebenfalls eine U-Profilschiene mit jeweils zwei Doppelsicken 4 jeweils in der Stegfläche 1 und in den Seitenflächen 2, wobei die Doppelsicken 4 beispielsweise die Querschnittsgestalt nach Fig. 2 haben. Zusätzlich sind hierbei aber zur weiteren Versteifung der U-Profilschiene mehrere Doppelsicken 4 auch in Querrichtung der U-Profilschiene angeordnet. Wie in Fig. 6 links vorn dargestellt ist, verläuft die dort gezeigte Quer-Doppelsicke 4 aus den Seitenwänden 2 um die zwischen den benachbarten Profilwänden 1, 2 gebildeten Profilkanten 8 herum bis in die Stegfläche hinein. Beim Beispiel nach Fig. 6 sind diese Quersicken in der Stegfläche nur durch die längsverlaufenden Quersicken 4 unterbrochen.FIG. 6 also shows a U-shaped rail, each with two double beads 4 in the web surface 1 and in the side surfaces 2, the double beads 4 having, for example, the cross-sectional shape according to FIG. 2. In addition, several double beads 4 are also arranged in the transverse direction of the U profile rail for further stiffening of the U profile rail. As shown in FIG. 6 at the front left, the transverse double bead 4 shown there extends from the side walls 2 around the profile edges 8 formed between the adjacent profile walls 1, 2 and into the web surface. In the example according to FIG. 6, these transverse beads are only interrupted in the web surface by the longitudinal transverse beads 4.

Abweichend davon ist in Fig. 7 bei einem ansonsten gleichen Ausführungsbeispiel dargstellt, daß die querverlaufenden Doppelsicken 4 aus im Abstand zueinander verlaufenden, miteinander fluchtenden Sickenabschnitten 4a bestehen. Die Ausführung der querverlaufenden Doppelsicken 4 kann auch so gewählt werden, daß sich an einen um eine Profilkante 8 herumgeführten Sickenabschnitt ein damit fluchtender Sickenabschnitt im Abstand anschließt.Deviating from this, it is shown in FIG. 7 in an otherwise identical exemplary embodiment that the transverse double beads 4 consist of bead sections 4a running at a distance from one another and aligned with one another. The design of the transverse double beads 4 can also be selected so that a bead section aligned therewith is spaced apart from a bead section which is guided around a profile edge 8.

In den Fig. 8 und 9 ist ein weiteres Ausführungsbeispiel eines mit Doppelsicken 4 versteiften Blechprofilteils dargestellt, nämlich ein U-förmiger Kreuzverbinder 9, der zur Verbindung von sich kreuzenden Profilschienen, beispielsweise C-Profilschienen 10, 11 dient.8 and 9 show a further exemplary embodiment of a sheet-metal profile part stiffened with double beads 4, namely a U-shaped cross connector 9, which is used to connect intersecting profile rails, for example C-profile rails 10, 11.

Der Kreuzverbinder 9 weist zwei durch ein Steg-Mittelstück 12 verbundene, rechtwinklig dazu abgewinkelte U-Schenkel 13 auf. Seitliche Einschnitte 14 an den U-Schenkeln dienen zur Aufnahme der Flanschflächen der in den Fig. 8 und 9 jeweils unten dargestellten C-Profilschiene 11.The cross connector 9 has two U-legs connected by a web center piece 12 and angled at right angles thereto 13 on. Lateral incisions 14 on the U-legs serve to accommodate the flange surfaces of the C-shaped rail 11 shown in FIGS. 8 and 9 below.

Die beiden Doppelsicken 4 laufen parallel und im Abstand zueinander von dem einen U-Schenkel 13 über das Steg-Mittelstück 12 in den zweiten U-Schenkel 13 durch und bewirken eine erhebliche Versteifung des Kreuzverbinders 9 ohne wesentliche Erhöhung einer Dicke. Der Kreuzverbinder 9 kann daher aus verhältnismäßig dünnem Blech hergestellt werden.The two double beads 4 run parallel and at a distance from one another from one U-leg 13 via the web center piece 12 into the second U-leg 13 and bring about a considerable stiffening of the cross connector 9 without a substantial increase in thickness. The cross connector 9 can therefore be made of relatively thin sheet metal.

Ein weiteres Anwendungsbeispiel für S-förmige Doppelsicken als Versteifungselemente für flache, dünnwandige Blechprofilteile ist in den Fig. 10 und 11 dargestellt. Es handelt sich dabei um einen Abhänger für Unterdecken od.dgl. Ein im wesentlichen flaches, senkrechtes Flächenteil 15 des Abhängers, das Bohrungen 16 zur Verbindung mit einem weiteren (nicht dargestellten) Teil des Abhängers aufweist, ist nahe seinen beiden Rändern mit zwei senkrecht verlaufenden Doppelsicken 4 versehen, die parallel und im Abstand zueinander verlaufen. Die beiden Doppelsicken 4, die beispielsweise in der Querschnittsgestaltung gemäß Fig. 2 ausgeführt sind, erstrecken sich nach unten bis in einen verbreiterten Halteabschnitt 17 des Abhängers, der seitliche Einschnitte 18 bzw. 19 zur Aufnahme von Flanschen einer C-Profilschiene bzw. eines horizontalen Haltebleches aufweist. Zur weiteren Verstärkung des verbreiterten Halteabschnitts 17 sind schräg ansteigende Versteifungssicken 20 vorgesehen. Diese können als einfache Sicken oder wiederum als Doppelsicken, beispielsweise gemäß Fig. 2, ausgeführt sein.Another application example for S-shaped double beads as stiffening elements for flat, thin-walled sheet metal profile parts is shown in FIGS. 10 and 11. It is a hanger for suspended ceilings or the like. A substantially flat, vertical surface part 15 of the hanger, which has bores 16 for connection to a further (not shown) part of the hanger, is provided near its two edges with two perpendicular double beads 4, which run parallel and at a distance from one another. The two double beads 4, which are designed, for example, in the cross-sectional configuration according to FIG. 2, extend downward into a widened holding section 17 of the hanger, the lateral incisions 18 and 19 for receiving flanges of a C-shaped rail or a horizontal holding plate having. To further reinforce the widened holding section 17, obliquely rising stiffening beads 20 are provided. These can be designed as simple beads or again as double beads, for example according to FIG. 2.

Fig. 11 läßt die Querschnittsgestaltung des senkrechten Flächenteils 15 mit den darin eingeformten Doppelsicken 4 deutlich erkennen.Fig. 11 clearly shows the cross-sectional design of the vertical surface part 15 with the double beads 4 molded therein.
