Abstract
Description
Die Erfindung betrifft ein Blechprofilteil mit im wesentlichen ebenen Profilwänden mit in entgegengesetzten Richtungen aus der Blechebene verformten Sicken. 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 part with essential flat profile walls with in deformed in opposite directions from the plane of the sheet Beads. Beads are used in many different ways Sheet metal parts used for stiffening. You raise the stiffness of the sheet metal profile parts and enable hence the use of relatively thin sheet metal, without an inadmissible reduction in the stiffness of the sheet metal 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 in the form of straight or curved channels essentially flat sheet metal surfaces pressed or rolled. This reshaping takes place without any significant change in Sheet thickness. The beads formed in this way are each made of one Arched 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 have several in sheet metal profile parts to provide parallel or non-parallel beads. The the resulting stiffening effect depends on the Cross-sectional shape of the individual beads and in particular on the height of the bead, i.e. of the extent to which the Bead is arched out of the sheet metal level. With increasing height of the bead is only one to achieve a smaller increase in the stiffening effect. In addition, relatively high beads have the disadvantage that that the adjacent sheet metal material in the bead is drawn in because of the creation of the bead performed forming process is a deep-drawing process. In addition comes that too high beads when connecting the Can interfere with sheet metal part with other components. The stiffening effect to be achieved therefore finds in in most cases its limit is that the height of the Beading 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 verhältnismäßig geringer Abmessungen eine wesentlich erhöhte Versteifungswirkung gegenüber herkömmlichen Sicken erzielt wird, ohne daß die genannten Nachteile eintreten.The object of the invention is therefore a sheet metal profile part the genus mentioned in such a way that by the use of beads relatively less Dimensions a significantly increased stiffening effect compared to conventional beads without the mentioned disadvantages occur.
Bei einem bekannten Blechprofil (CH-A-406 583) sind einzelne Profilwände im Querschnitt durchgehend wellenförmig profiliert. Dadurch wird zwar gegenüber einer flachen Wand eine erhöhte Formsteifigkeit erreicht; es stehen aber keine im wesentlichen flachen Bereiche der Profilwand zur Verfügung, die für Durchbrechungen oder das Einschrauben selbstschneidender Bauschrauben verwendet werden könnten.In a known sheet profile (CH-A-406 583) individual profile walls in cross section wavy profiled. This is true compared to one flat wall achieves increased stiffness; it but there are no essentially flat areas of the Profile wall available for breakthroughs or that Screwing in self-tapping screws used could become.
Bei einem bekannten Blechprofilteil der eingangs genannten Gattung (GB-A-2 164 966, Fig. 1) sind im Abstand zueinander zwei parallellaufende Einzelsicken in entgegengesetzten Richtungen aus der Blechebene geformt. Der Übergang jeweils von einer Einzelsicke in den zwischen den beiden Blechsicken liegenden mittleren Bereich ist fertigungstechnisch verhältnismäßig kompliziert. Die beiden Einzelsicken nehmen hierbei bereits angenähert die Hälfte der Flächenbreite ein, so daß für Durchbrüche oder Schraubbefestigungen nur sehr wenig Fläche zur Verfügung steht. Daneben sind aus dieser Veröffentlichung Ausführungen von Blechprofilteilen bekannt (Fig. 3 und 4), bei denen nahezu die gesamte Stegwandfläche nach beiden Seiten hin profiliert ist. Damit stehen abgesehen von schmalen, hierfür nicht nutzbaren Randstreifen keine im wesentlichen ebenen Profilflächen zur Verfügung, die für Durchbrechungen oder das Eindrehen von selbstschneidenden Bauschrauben genutzt werden könnten.In a known sheet metal profile part of the aforementioned Genus (GB-A-2 164 966, Fig. 1) are at a distance to each other two parallel beads in opposite directions formed from the sheet metal plane. The transition from a single bead to the between the middle area lying between the two sheet metal beads relatively complicated to manufacture. The the two individual beads already take the approximate Half of the area width, so that for breakthroughs or Screw fastenings only very little space available stands. Beside are from this publication Designs of sheet metal profile parts known (Fig. 3 and 4), where almost the entire web wall area after both Sides is profiled. With that stand apart from narrow, not usable edge strips none in the essential flat profile surfaces available for Breakthroughs or the insertion of self-tapping Building screws could be used.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jeweils zwei in entgegengesetzten Richtungen auf der Blechebene verformte einzelne Sicken eine Doppelsicke bilden und daß die eine Sicke unmittelbar in einem zur anderen Seite ansteigenden Übergangsabschnitt in die andere Sicke übergeht.This object is achieved in that two each in opposite directions on the Individual corrugations deform a double corrugation form and that the one bead immediately in a to on the other side rising transition section into the other bead goes over.
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.These double beads result in a relatively small amount Bead height a much greater stiffening effect than two spaced apart, equally large Beads. It can be assumed that the immediate transition between the two individual beads that together form the Form double beads, i.e. avoiding a between the two beads lying in the sheet metal plane Sheet metal strip, essential to that in a surprising way contributes to the increased stiffening effect.
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 with relatively low Height are executed, the neighboring one Sheet material during the forming process not or only very little pulled transversely into the bead area so that disruptive deformation of the sheet metal part avoided will.
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 an elongated sheet metal part in a flat Profile area. Compared to usual edge profiles of elongated sheet metal profile parts results with the double beads according to the invention a particularly good one Stiffening effect for the sheet metal part if the Double bead runs in a flat profile area that means if the double bead is level on both sides Connect sheet metal surfaces, for example the web surface a U or C profile. Is of particular importance here also that the double beads in the longitudinal direction of the profile run because this - with simple manufacture - just the typical properties of an elongated Sheet profile part (rail) can be significantly improved, 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 provided that the double bead approximately in cross section S-shaped. This will have sharp edges or small radii of curvature avoided.
Stattdessen kann aber auch vorgesehen werden, daß die Doppelsicke im Querschnitt annähernd Z-förmig geformt ist. Dadurch ergibt sich eine besonders gute Versteifungswirkung.Instead, it can also be provided that the Double bead is approximately Z-shaped in cross section. This results in a particularly good one Stiffening effect.
Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand weiterer Unteransprüche.Further advantageous embodiments of the The idea of the invention is the subject of further Subclaims.
Die Erfindung wird nachfolgend an Ausführungsbeispielen
näher erläutert, die in der Zeichnung dargestellt sind. Es
zeigt:
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 2.1 as an example of a sheet metal profile part

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 Ãœbergangsbereich
7 ineinander über, der kontinuierlich von der einen Sicke
5 zur anderen Sicke 6 ansteigt. Im Ãœbergangsbereich 7 gibt
es daher keinen Blechabschnitt, der in der Blechebene der
Stegfläche 1 verlaufen würde. der Übergangsbereich 7
verläuft vielmehr kontinuierlich in einem ansteigenden
Winkel zur Blechebene.As shown enlarged in cross section in FIG. 2,

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 shown in Fig. 2 and the sheet metal part after
Fig. 1
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
Ãœbergangsbereich 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 are the double beads 4 ', which in the
3 can be used and in
4 enlarged cross section are shown in
Z-shaped cross-section. Each of the two
Beading 5 'and 6', which form the double bead 4 ', exist
from an approximate right angle from the surrounding
Sheet surface, for example the

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-profile rail with each
two
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 is otherwise in FIG. 7

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
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
