Description

Seite Beschreibung: Page Description:

Die Erfindung betrifft einen Bl echprofilträger nach dem Oberbegriff des Hauptanspruchs. Es ist ein Blechprofiltrager bekannt, dessen Obergurt Querrippen (Quersicken) aufweist (Patentschrift DE 2616058 C2). Die Querrippen dieses bekannten Blechprofi1 tragers sind so ausgeführt, daß sich die Stegneigung bei einer abwa'rts gerichteten Belastung des Obergurtes verringert und sich damit auch die Gesamthö'he des Bl echprofi 1 tra'gers verkleinert. Es ist allgemein bekannt, daß sich durch dieses Tragverhalten die Belastbarkeit eines Blechprofi1trffgers mit trapezförmigem Querschnitt verringert. Dieses Tragverhalten kann mit der bekannten Ausführung der Querrippen nicht verändert werden.The invention relates to a Bl echprofilträger after Preamble to the main claim. A sheet metal profile girder is known, the upper flange of which has transverse ribs (transverse beads) (Patent DE 2616058 C2). The cross ribs this well-known sheet metal professional are designed in such a way that that the web inclination decreases with a downward load on the upper chord, and thus also decreases the total height of the Bl echprofi 1 carrier has been reduced. It is well known that this behavior the resilience of a sheet metal profile door with trapezoidal Reduced cross-section. This load-bearing behavior cannot be achieved with the known design of the transverse ribs to be changed.

Der Erfindung liegt die Aufgabe zugrunde, einen Blechprofiltrager nach dem Oberbegriff des Anspruchs 1. zu schaffen, der eine verbesserte Tragwirkung aufweist.The invention is based on the object of a sheet-metal profile support to create according to the preamble of claim 1, which has an improved load-bearing effect.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1. gegebenen Merkmale gelöst. Der Obergurt wird erfindungsgemaß mit einer konvexen Profilierung (7) versehen, so daß bei einer abwärts gerichteten Belastung des Obergurtes horizontale, nach außen gerichtete Kra'fte entstehen, welche in ihrer Tendenz die Stegneigung und damit die Belastbarkeit des Blechprofil trägers als Dach- oder als Wandtrffger vergrößern. This task is carried out by the in the characterizing part of the Claim 1. given features solved. According to the invention, the top chord is convex Profiling (7) provided so that a downward directed loading of the upper chord, horizontal, outwardly directed forces arise, which in their tendency increase the web inclination and thus the resilience of the sheet metal profile as a roof or wall support.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausffihrungsbeispiels na'her erläutert. Es zeigenIn the following the invention with reference to the Drawing explained in more detail using an exemplary embodiment. Show it

Fig.l eine perspektivische Ansicht einer AusfCfhrungsform eines Blechprofilträgers; die Belastung des Obergurtes ist durch die eingetragenen Lastpfeile gekennzeichnet, Fig.2 einen Querschnitt des Blechprofiltragers gemäß Linie I-I, Fig.l,Fig.l is a perspective view of an embodiment a sheet metal profile support; the load on the top chord is indicated by the load arrows entered, FIG. 2 shows a cross section of the sheet metal profile support according to Line I-I, Fig. 1,

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.3 shows the characteristic parts of the cross-section in separate representation with entry of the load and the direction of displacement of the corner edges (4), 4 shows an embodiment of the profiling of the Upper chord in plan view and in section II-II.

Durch die konvexe Formgebung des Obergurtes entstehen vertikal gerichtete Krä'fte V und horizontal gerichtete Kra'fte H (Fig.3), die mit der Belastung ein Gleichgewi chtssystem 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 Üblichen 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 Versteifungssicken nach Anspruch 2. - möglich, größere Spannweiten bei geringerem Eigengewicht der Blechprofi1 träger zu erreichen.The convex shape of the upper chord results in vertically directed forces V and horizontally directed forces Forces H (Fig. 3), which are in equilibrium with the load form the control system. The horizontally directed forces H act on the two webs in such a way that the web inclination is increased. The profiling of the top flange is like this stated that with the usual loads this deformation behavior dominates and that a bottoming out of the top chord downwards with the required Security does not occur. Due to the load-bearing effect achieved in this way, it is - in connection with the stiffening beads according to claim 2 - possible, larger spans with a lower weight of the Blechprofi1 girders reach.
