Unter dem Abwinklungsbereich wird die Länge der zweiten Seitenwand verstanden, welche zwischen der tangential an den Abbiegeradius angrenzenden als Sickenwände ausgebildeten Längsstegen und dem Sickenboden liegt. Die flächige Auflage ermöglicht eine verbesserte Krafteinleitung als es bei einer linienförmigen, bzw. punktförmigen Auflage gegeben ist. Das erfindungsgemässe Hohlprofil kann des Weiteren bezogen auf die X-Achse des Querschnitts vertikal oder horizontal ausgerichtet angeordnet werden, wobei dessen statischen Eigenschaften gegenüber den bekannten Lösungen vorteilhafter ist. Der Abwinklungsbereich liegt zwiebelschalenförmig an dem Aufnahmebereich an. Ein Ausgleiten der abgestützten Fläche aus der stützenden Fläche ist durch die Ausgestaltung des Aufnahmebereichs der ersten Seitenwand und infolge des flächigen Kontakts zwischen dem Abwinklungsbereich und dem Aufnahmebereich verhindert.The Abwinklungsbereiche between the bead bottom and the bead walls of the second Side wall are completely at the receiving areas of the first side walls and in the Essentially without a distance to each other at this.

Das erfindungsgemässe Hohlprofil ist vorzugsweise aus einem Stahlblech gefaltet und an dessen freien Rändern, beispielsweise mit einer Längsnaht, zur Schaffung des geschlossenen Hohlprofils verschweisst oder verlötet. Eine weitere Verbindungsmöglichkeit der freien Ränder stellen Klebeverbindungen dar. Soll das Hohlprofil beispielsweise unterschiedliche Materialeigenschaften der ersten und der zweiten Seitenwände aufweisen, kann für die ersten Seitenwände ein anderes Ausgangsmaterial als für die zweiten Seitenwände zur Fertigung des Hohlprofils verwendet werden, wobei die freien Ränder aneinander gereihter Abschnitte, beziehungsweise Seitenwände miteinander verbunden werden.The hollow profile according to the invention is preferably folded from a sheet steel and on its free edges, for example with a longitudinal seam, to create the closed Hollow profiles welded or soldered. Another way to connect the free Edges are adhesive joints. If the hollow profile, for example, different Material properties of the first and second side walls, may be for the first Side walls a different starting material than for the second side walls to manufacture of the hollow profile, the free edges of juxtaposed sections, or side walls are connected to each other.

Bevorzugt schliessen sich an die Abwinklungsbereiche zwischen dem Sickenboden und den, die Sickenwände ausbildenden Längsstegen zumindest einseitig Auflagebereiche an, die flächig an den Anlagebereichen der ersten Seitenwände anliegen. Mittels der damit geschaffenen Vergrösserung des Kontaktbereichs zwischen der ersten und zweiten Seitenwand lassen sich höhere Kräfte zwischen den ersten und zweiten Seitenwänden übertragen. Vorzugsweise schliessen sich an beiden Enden jedes Abwinklungsbereichs jeweils ein Auflagebereich an. Dabei ist es besonders vorteilhaft, wenn der, die Sickenwand ausbildende Längssteg der zweiten Seitenwand durch die Faltung aufgedoppelt ist. Dieser Schenkel der U-förmig ausgestalteten zweiten Seitenwand bildet dabei einen in Längsrichtung des Hohlprofils verlaufenden Längssteg auf, der eine Dicke etwa der zweifachen Materialstärke des flächigen Materials aufweist. Der Abwinklungsbereich und die benachbarten Auflagebereiche liegen zwiebelschalenförmig an dem Aufnahmebereich an. Bei dieser Ausführungsform ist ein Ausgleiten der abgestützten Fläche aus der stützenden Fläche auch bei höheren Belastungen weitgehend verhindert.Preferably, close to the Abwinklungsbereiche between the bottom of the bead and the, the bead walls forming longitudinal webs on at least one side bearing areas, the lie flat against the contact areas of the first side walls.

Diese Querstege dienen insbesondere der Auflage des erfindungsgemässen Hohlprofils auf sich kreuzenden Hohlprofile oder sonstigen Trägern, beziehungsweise zur Auflage des erfindungsgemässen Hohlprofils auf einem Untergrund. Die Querstege schaffen, gegenüber einer Linienauflage der Längsstege eine vergrösserte Auflagefläche, was beispielsweise die Linien- oder Punktlast an den Kontaktpunkten der Lagerung des Hohlprofils reduziert. Besonders bei Ausgestaltungen des Hohlprofils mit tiefen Sicken und entsprechend hohen Sickenwänden, beziehungsweise Schenkeln der U-förmigen zweiten Seitenwand können bei hohen Belastungen auf des Hohlprofil die Schenkel der U-förmigen zweiten Seitenwand unter der Last ausknicken.Advantageously, at the free ends of the, the bead walls forming longitudinal webs each outwardly directed transverse webs are formed, which are substantially parallel to the Laying planes, which are spanned by the bottom of the bead.
