Description
Kranbahnträger Es sind. Kranbahnträger mit I-förmigem Querschnitt bekannt, bei denen zur Aufnahme der Seitenkräfte der Obergurt an seinen äußeren Zonen verstärkt ist. Zu diesem Zweck hat man bisher als Obergurt ein I-oder U-Profil gewählt, an dieses in der Stegmitte das Stegblech des Kranbahnträgers und an dieses wiederum den von einem ebenen Blech gebildeten Untergurt angeschweißt. Danach wurde die Fahrschiene in der Stegebene des Träger auf dessen Obergurt aufgelegt und mit diesem verbunden. Crane runway girders There are. Crane runway girders with an I-shaped cross-section known where to absorb the side forces of the top chord on its outer Zones is reinforced. For this purpose, an I or U profile has hitherto been used as the top flange selected, to this in the web center the web plate of the crane runway girder and to this in turn welded on the lower chord formed by a flat sheet metal. After that it was the running rail is placed on the girder's top chord and with connected to this.
Die handelsüblichen Profile entsprechen hinsichtlich der für den vorliegenden Zweck beabsichtigten Verteilung des Gewichtes im Obergurt des Fahrbahnträgers nicht den hierfür günstigsten Werten, so daß die Querschnittsfläche der beiden Stege nicht so weit ausgenutzt werden kann, wie es wünschenswert ist. Außerdem bereitet das Anschließen des Trägerstegs am Steg des I-oder U-Profils wegen der hier schlechten Zugänglichkeit Schwierigkeiten. The commercially available profiles correspond to those for the intended distribution of the weight in the top chord of the roadway girder for the present purpose not the most favorable values for this, so that the cross-sectional area of the two webs cannot be exploited as far as is desirable. Also prepares connecting the support web to the web of the I or U profile because of the bad here Accessibility difficulties.
Beim Kranbahnträger nach der Neuerung werden diese Mängel durch ein als Obergurt dienendes Profil vermieden, das in seiner Symmetrieebene eine Nase aufweist, an deren Stirnkante der Steg des Kranbahnträgers angeschweißt ist. With the crane runway girders after the innovation, these defects are caused by a Avoided serving as a top chord profile that has a nose in its plane of symmetry has, to the front edge of which the web of the crane runway girder is welded.
Ein nur dem genannten Zweck dienendes Profil kann im übigen einen Querschnitt erhalten, welcher der Forderung nach weitgehender Ausnutzung der Querschnittsfläche entspricht. Außerdem bietet sich dann zugleich die Möglichkeit, die Fahrschiene in das Profil mit einzubeziehen, so daß emne besondere Schiene und deren Befestigungsmittel in Fortfall kommen.A profile that only serves the stated purpose can be used in a Cross-section obtained, which meets the requirement for extensive utilization of the cross-sectional area is equivalent to. In addition, there is also the possibility of using the rail to be included in the profile, so that a special rail and its fastening means come in failure.
In der Zeichnung ist ein Kranbahnträger nach dem Vorschlag der Neuerung im Querschnitt dargestellt. In the drawing is a crane runway girder according to the proposal of the innovation shown in cross section.
Der Obergurt 1 ist an seinen Randzonen 1a den Erfordernissen der Belastung entsprechend verstärkt und weist in seiner Symmetrieebene eine Rippe 1b auf, an die der Steg 2 angeschlossen ist, der in dem Untergurt 3 endet. Die Erhöhung 1c des Obergurtes 1 dient als Fahrschiene. The upper belt 1 is at its edge zones 1a the requirements of The load is increased accordingly and has a rib 1b in its plane of symmetry to which the web 2 is connected, which ends in the lower flange 3. The increase 1c of the top chord 1 serves as a running rail.
