Description
Es ist bekannt, bei Drehscheiben mit geteilten Hauptträgern die beiden Hauptträgerteile durch Blattgelenke aneinander anzuschließen. Dabei wurden die Blechstreifen, welche das Blattgelerik bilden sollten, entweder wagerecht angeordnet, wobei dann zur Aufnahme der in senkrechter Richtung auftretenden Kräfte noch besondere Vorkehrungen getroffen werden mußten, oder aber die Gelenkblätter wurden senkrecht gestellt, so daß sie auf Zug beansprucht wurden, wobei gegen wagerechte Verschiebungen noch besondere Maßnahmen nötig waren. Eine Verbindung von sowohl wagerechten als auch senkrechten Blattgelenken ist auch schon vorgeschlagen, hat aber wegen der ungünstigen Beanspruchungen der Bauteile keine Verbreitung gefunden.It is known that in turntables with split main girders, the two main girder parts to be connected by leaf joints. The sheet metal strips, which were supposed to form the leaf gel, were either arranged horizontally, then to accommodate the occurring in the vertical direction Forces, special precautions had to be taken, or else the joint blades were placed vertically, so that they were stressed in tension, with particular ones against horizontal displacements Measures were necessary. A connection of both horizontal and vertical leaf joints has also been proposed, However, due to the unfavorable stresses on the components, it is not widespread found.
Die Erfindung geht von der vorerwähnten Anordnung, wobei das als Blattgelenk· dienende Blech auf Zug beansprucht wird, aus. Das Neue ist, daß dieses Gelenkblech (Hängeblech) geneigt angeordnet wird, und zwar derart, daß die inneren Hauptträgerensden durch den ständig auftretenden schrägen Zug ständig gegeneinandergedrückt werden.The invention is based on the aforementioned arrangement, with the sheet metal serving as a leaf hinge being subjected to tensile stress. The new thing is that this hinge plate (hanging plate) is inclined, namely such that the inner main girders are denied by the constantly occurring oblique pull are constantly pressed against each other.
Eine besonders wagerechte Verbindung der beiden Trägerenden ist also nicht mehr erforderlich, da der ständig wirkende Zug e;ne solche ersetzt; ebenso können Maßnahmen zur Sicherung dter Höhenlage der Trägerenden fortfallen, da sich das Gelenkblatt genügend kräftig ausbilden läßt.A particularly horizontal connection of the two girder ends is no longer necessary, since the constantly acting train e ; ne such replaced; Likewise, measures to secure the height of the girder ends can be omitted, since the hinge leaf can be made sufficiently strong.
In der Zeichnung ist eine Ausführungsform der Erfindung dargestellt, und zwar zeigt dieselbe den mittleren Teil der Hauptträger einer Gelenkdrehscheibe. In the drawing, an embodiment of the invention is shown, namely shows the same the middle part of the main beams of an articulated turntable.
Der linke Hauptträger.a ist mit <Ien Querträgern b des Königsstuhls in bekannter Weise fest verbunden. Der Anschluß des zweiten Hauptträgers erfolgt durch das Gelenkblech d, das an den abgeschrägten Enden der beiden Hauptträger so angeordnet ist, daß es eine geneigte Lage einnimmt.The left main beam a is firmly connected to the cross beams b of the king's chair in a known manner. The connection of the second main beam takes place through the hinge plate d, which is arranged at the beveled ends of the two main beams in such a way that it assumes an inclined position.
Es ist ohne weiteres ersichtlich, daß unter dem Einfluß der Eigenlast und Nutzlast die beiden Trägerenden ständig gegeneinandergepreßt werden. Bei einer gegenseitigen Bewegung der beiden Trägerteile biegt sich das Verbindungsblech durch und schmiegt sich hierbei an die entsprechend abgerundeten Stirnenden der Träger an. Die Abrundungen, in der Zeichnung durch Schraffierung gekennzeichnet, sind so bemessen, daß eine möglichst günstige Beanspruchung des Gelenkblattes erfolgt.It is readily apparent that under the influence of dead weight and payload the both ends of the beam are constantly pressed against each other. With a mutual movement of the two support parts, the connecting plate bends and hugs the correspondingly rounded ones Forehead of the carrier. The roundings, in the drawing by hatching marked, are dimensioned so that the most favorable possible stress on the hinge leaf he follows.
