Description
Zweiteilige Eisenbetonschwelle, bei welcher die Teile durch ein waagerechtes Flachfedergelenk aus Eisen verbunden sind Durch die auf beide Enden gleichzeitig wirkenden Radlasten werden die Eisenbetonschwellen in der Mitte so ungünstig auf Biegung beansprucht, daß sie nach kürzer Zeit an dieser Stelle brechen. L.'m diesen Übelstand zu beseitigen., hat man bereits die Schwellen in zwei gleiche Teile zerlegt und diese durch ein Flacheisen verbunden.Two-part reinforced concrete sleeper, in which the parts are separated by a horizontal Flat spring hinges made of iron are connected by acting on both ends at the same time acting wheel loads, the reinforced concrete sleepers in the middle are so unfavorable Bending claims that they break at this point after a short time. L.'m this one To eliminate the problem, the sleepers have already been divided into two equal parts and connected by a flat iron.
Die Verbindung beider Schwellenteile war aber bisher sehr unzweckmäßig, da das die Teile verbindende Flacheisen entweder die Verbindung sehr umständlich durch Schrauben, die nur in je einem besonders auf beide Schwellenteile aufzulegenden Flacheisen angebracht werden konnten, herstellte oder, da die Flacheisen nicht in der waagerechten Biegungsebene lagen, sondern senkrecht dazu standen und die beiden inneren Stirnflächen der Schwellenteile so hart mit geraden Flächen aneinanderstießen, daß ein Nachgeben der Schwellenteile bei einseitig auftretendem senkrechten Druck ohne Bruch derselben nicht stattfinden konnte.The connection of both sleeper parts has been very inexpedient so far, since the flat iron connecting the parts either the connection is very cumbersome by screws, which only need to be placed on both sleeper parts in one of each Flat irons could be installed, or, since the flat irons are not in the horizontal bending plane, but were perpendicular to it and the two inner end faces of the sleeper parts butted so hard with straight surfaces that that a yielding of the sleeper parts with unilaterally occurring vertical pressure could not take place without breaking it.
Diese Nachteile beseitigt die Erfindung dadurch, daß eine zweiteilige Eisenbetonschwelle, die an ihren inneren, zweckmäßig gewölbten Stirnflächen durch ein Flacheisen verbunden ist, und daß ein oder beide Schwellenteile mit Buchsen oder Aussparungen entsprechend der Form der Enden des darin seitlich einzuschiebenden Verbindungsstückes versehen sind.The invention eliminates these disadvantages in that a two-part Reinforced concrete sleeper, which through its inner, appropriately arched end faces a flat iron is connected, and that one or both sleeper parts with bushings or recesses corresponding to the shape of the ends of the laterally inserted therein Connector are provided.
Die Zeichnung gibt verschiedene Ausführungsarten des Erfindungsgegenstandes wieder.The drawing shows various types of embodiment of the subject matter of the invention again.
Abb. i zeigt eine Seitenansicht und Abb. 2 eine Draufsicht auf eine als Federgelenk d wirkende Flachgelenkverbindung aus H-förmigem Profileisen, das in Buchsen c eingeschoben wird, welche in den Schwellenteilen a, b fest einbetoniert sind. Der Steg des Profileisens verbindet die beiden Schwellenteile a, b und muß, gegebenenfalls die Biegungsbeanspruchungen übernehmen; im allgemeinen wird aber bereits der geringe Spielraum zwischen dem H-förmigen Verbindungsstück und der entsprechenden Buchse des Schwellenteiles als Gelenk genügen.Fig. 1 shows a side view and Fig. 2 shows a plan view of a flat joint connection, which acts as a spring joint d, is made of H-shaped profile iron and is pushed into sockets c which are firmly concreted in the sleeper parts a, b. The web of the profile iron connects the two sleeper parts a, b and must, if necessary, take over the bending stresses; In general, however, the small clearance between the H-shaped connecting piece and the corresponding socket of the sleeper part will suffice as a joint.
Abb..3 zeigt ein Federgelenk d aus H-förmigem Profil, dessen eine Hälfte in dem einen Schwellenteil b fest einbetoniert ist und dessen andere Hälfte in eine Buchse c eingeschoben wird, welche im anderen Schwellenteil a. fest einbetoniert ist.Fig..3 shows a spring joint d made of an H-shaped profile, one of which Half in which a threshold part b is firmly concreted in and the other half is inserted into a socket c, which in the other threshold part a. firmly set in concrete is.
Abb. q. zeigt ein Federgelenk d aus H-förmigem Profil, dessen flache Hälfte fest einbetoniert und dessen Steg in eine im anderen Schwellenteil a fest einbetonierte Buchse c eingeschoben wird.Fig.q. shows a spring hinge d made of an H-shaped profile, its flat Half firmly concreted in and its footbridge into one in the other sleeper part a concreted socket c is inserted.
Abb. 5 zeigt ein Federgelenk d aus einteiligem Wulsteisen, dessen flache Hälfte fest einbetoniert ist und dessen Wulst in eine im anderen Schwellenteil a fest einbetonierte Buchse c eingeschoben wird.Fig. 5 shows a spring joint d made of one-piece bead iron, its flat half is firmly set in concrete and its bead in one in the other sleeper part a firmly concreted-in socket c is inserted.
Abb. 6 zeigt ein Federgelenk d aus doppeltem Wulsteisen, das in Büchsen c, welche in beiden Schwellenteilen a, b fest einbetoniert sind, eingeschoben wird.Fig. 6 shows a spring joint d made of double bead iron, which is in bushings c, which are firmly embedded in concrete in both sleeper parts a, b.
