Bewegliches Lager für Brücken und ähnliche Bauwerke.Movable warehouse for bridges and similar structures.

Patentiert im Deutschen Reiche vom 12. Juni 1906 ab.Patented in the German Empire on June 12, 1906.

Die Erfindung betrifft ein bewegliches Lager für Brücken und ähnliche Bauwerke, welches sowohl zur Aufnahme der Druckkräfte als auch der etwa auf das Lager wirkenden Zugkräfte geeignet ist und wobei die obere und untere Platte des Lagers während der Längenänderungen zwangläufig parallel geführt werden.The invention relates to a movable bearing for bridges and similar structures, which is suitable both for absorbing the compressive forces and the tensile forces acting on the bearing, for example the upper and lower plate of the bearing are necessarily guided in parallel during the changes in length.

Diese Aufgabe wurde bisher meist so gelöst, daß von dem Drucklager unabhängige Verankerungen angeordnet werden, welche indessen die Beweglichkeit des Lagers beeinträchtigen. Die Trennung der Druck- und Zugglieder erschwert die Ausführung, nimmt viel Raum ein, verursacht große Kosten und ergibt doch keine vollkommene Geradführung. This task has so far mostly been solved in such a way that it is independent of the thrust bearing Anchors are arranged, which, however, impair the mobility of the bearing. The separation of the compression and tension members complicates the execution, takes up a lot of space, causes great costs and does not result in a perfect straight line.

Die Erfindung besteht darin, daß die Lagerplatten, zwischen denen der wie üblich dieThe invention consists in that the bearing plates between which the as usual the

ao Druckkräfte übertragende bewegliche Lagerkörper (Kugel, Walze oder Pendel) sich bewegt, durch eine Gelenkgeradführung miteinander verbunden sind, welche, die auf das Lager wirkenden Zügkräfte überträgt, ohne die parallele Bewegung der Lagerteile gegeneinander zu hindern.ao movable bearing body (ball, roller or pendulum) transmitting pressure forces moves, are connected to each other by an articulated straight guide, which, on the Tension forces acting on the bearing are transmitted without the parallel movement of the bearing parts against each other to prevent.

Auf der Zeichnung sind zwei Ausführungsbeispiele der Erfindung in der Ansicht und im Schnitt dargestellt.In the drawing, two exemplary embodiments of the invention are shown in the view and shown in section.

Bei der Ausführungsform des Lagers nach den Fig. 1 und 2 liegt zwischen den Lagerplatten α und b ein die Druckkräfte übertragender beweglicher Lagerkörper, beispielsweise eine Kugel c. Die Platten α und b sind zu beiden Seiten durch ein gelenkiges Stabwerk von der Form einer Gelenkkette d, i miteinander verbunden, die sich in dem Punkt e an die Platte α und in den Punkten/ an die Platte b anschließt. Die Gelenkketten d, i übertragen die Zugkräfte und dienen gleichzeitig zur Geradführung der Platten α und b bei Längenänderungen des Überbaues.In the embodiment of the bearing according to FIGS. 1 and 2, a movable bearing body which transmits the compressive forces, for example a ball c, is located between the bearing plates α and b. The plates α and b are connected to one another on both sides by an articulated framework in the form of an articulated chain d, i , which connects to the plate α at point e and to the plate b at points /. The link chains d, i transmit the tensile forces and at the same time serve to guide the panels α and b in a straight line when the superstructure changes in length.

Bei dem neuen beweglichen Lager kann der die Druckkräfte übertragende Lagerkörper auch weggelassen und durch die Gelenkgeradführung ersetzt werden, so daß diese außer den auf das Auflager wirkenden Zugkräften auch die Druckkräfte überträgt.In the case of the new movable bearing, the bearing body which transmits the compressive forces can can also be omitted and replaced by the articulated straight guide, so that this not only transmits the tensile forces acting on the support but also the compressive forces.

In den Fig. 3 und 4 ist eine Ausführungsform dieses Lagers dargestellt. Hier liegt die gleichzeitig zur Übertragung der Druck- und Zugkräfte und zur Parallelführung dienende in dem Punkte e1 an die Platte α und in den Punkten f1 an die Platte b angeschlossene Gelenkkette d1, i1 mit ihren Enden in mittleren Aussparungen g und h der Platten α und b. 3 and 4, an embodiment of this bearing is shown. Here lies the same time serving for the transmission of the compressive and tensile forces and parallel guidance in the points e 1 α to the plate and in the points f 1 to the plate b connected articulated chain d 1, i 1 g at their ends in the middle recesses and h of the plates α and b.
