Definitions
- the invention relates to a sheet metal profile carrier according to the preamble of the main claim.
- a sheet metal profile carrier is known, the upper flange of which has transverse ribs (transverse beads) (patent specification DE 2616058 C2).
- the transverse ribs of this known sheet metal profile support are designed in such a way that the web inclination is reduced with a downward load on the top chord and thus the overall height of the sheet profile support is also reduced. It is generally known that the load-bearing capacity of a sheet-metal profile beam with a trapezoidal cross-section is reduced by this load-bearing behavior. This load-bearing behavior cannot be changed with the known design of the transverse ribs.
- the invention has for its object to provide a sheet profile support according to the preamble of claim 1, which has an improved load-bearing capacity. This object is achieved by the features given in the characterizing part of claim 1.
- the upper belt is provided according to the invention with a convex profiling (7), so as ß in a downward load of the upper flange horizontal arise outwardly directed forces, which in its tendency, the web inclination and thus the capacity of the Blechprofiltr g gers as roofing or as Enlarge wall bracket.

Abstract
Description
- Die Erfindung betrifft einen Blechprofilträger nach dem Oberbegriff des Hauptanspruchs. Es ist ein Blechprofilträger bekannt, dessen Obergurt Querrippen (Quersicken) aufweist (Patentschrift DE 2616058 C2). Die Querrippen dieses bekannten Blechprofilträgers sind so ausgeführt, daß sich die Stegneigung bei einer abwärts gerichteten Belastung des Obergurtes verringert und sich damit auch die Gesamthöhe des Blechprofilträgers verkleinert. Es ist allgemein bekannt, daß sich durch dieses Tragverhalten die Belastbarkeit eines Blechprofilträgers mit trapezförmigem Querschnitt verringert. Dieses Tragverhalten kann mit der bekannten Ausführung der Querrippen nicht verändert werden.
- Der Erfindung liegt die Aufgabe zugrunde, einen Blechprofilträger nach dem Oberbegriff des Anspruchs 1. zu schaffen, der eine verbesserte Tragwirkung aufweist. Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1. gegebenen Merkmale gelöst.
- Der Obergurt wird erfindungsgemäß mit einer konvexen Profilierung (7) versehen, so daß bei einer abwärts gerichteten Belastung des Obergurtes horizontale, nach außen gerichtete Kräfte entstehen, welche in ihrer Tendenz die Stegneigung und damit die Belastbarkeit des Blechprofiltrggers als Dach- oder als Wandträger vergroßern.
- Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispiels näher erläutert. Es zeigen
- Fig.1 eine perspektivische Ansicht einer Ausführungsform eines Blechprofilträgers; die Belastung des Obergurtes ist durch die eingetragenen Lastpfeile gekennzeichnet,
- Fig.2 einen Querschnitt des Blechprofilträgers gemäß Linie I-I, Fig.l,
- Fig.3 die kennzeichnenden Teile des Querschnittes in getrennter Darstellung mit Eintragung der Belastung und der Verschiebungsrichtung der Eckkanten (4),
- Fig.4 eine AusfUhrungsmöglichkeit der Profilierung des Obergurtes in der Draufsicht und im Schnitt II-II. Durch die konvexe Formgebung des Obergurtes entstehen vertikal gerichtete Kräfte V und horizontal gerichtete Kräfte H (Fig.3), die mit der Belastung ein Gleichgewichtssystem bilden. Die horizontal gerichteten Kräfte H wirken so auf die beiden Stege ein, daß die Stegneigung vergrößert wird. Die Profilierung des Obergurtes wird so ausgeführt, daß bei den Ublichen Belastungen dieses Verformungsverhalten dominiert und daß ein Durchschlagen des Obergurtes nach unten hin mit der erforderlichen Sicherheit nicht eintritt. Durch die damit erreichte Tragwirkung ist es - in Verbindung mit den Versteifungs- sicken nach Anspruch 2. - möglich, größere Spannweiten bei geringerem Eigengewicht der Blechprofilträger zu erreichen.
