PATENTAMT.PATENT OFFICE.
Man hat versucht, den Eisenbeton wegen seiner großen Druckfestigkeit und Widerstandsfähigkeit zum Ausbau von Strecken zu verwenden und hat auch mehrteilige, den hölzernen Türstöcken nachgebildete Türstöcke aus Eisenbeton benutzt, die jedoch den Nachteil haben, daß sie dem Gebirgsdruck nicht nachgeben können und deshalb bei großen Drücken zerstört werden. Die Erfindung betrifft einen mehrteiligen, aus Eisenbeton hergestellten Türstock, der so beschaffen ist, daß er auch ohne Verwendung zusammendrückbarer Polster aus Holz ο. dgl. lediglich infolge der Art der Zusammensetzung der starren Betonteile der Wirkung hoher Gebirgsdrücke nachgibt, so daß seine Zerstörung vermieden wird. Die Türstockbeine sind zu dem Zweck am oberen Ende mit walzenförmigen Rundungen versehen, die in Höhlungen der Kappen eingreifen. Bei hohem seitlichen Gebirgsdruck wird der Betontürstock verschoben. Dabei ergibt sich nur eine seitliche Verschiebung des Durchgangsquerschnittes, aber keine Verengung, und die Tragfähigkeit bleibt erhalten.One has tried the reinforced concrete because of its great compressive strength and resistance to use for the expansion of routes and also has multi-part door frames modeled on the wooden door frames Reinforced concrete used, but they have the disadvantage that they do not give way to the rock pressure and can therefore be destroyed at high pressures. The invention relates to a multi-part door frame made of reinforced concrete, which is made in such a way that it also without using compressible wooden cushions ο. Like. Only due to the nature of the The composition of the rigid concrete parts yields to the effect of high rock pressures, so that its destruction is avoided. The door frame legs are at the top for this purpose The end is provided with cylindrical roundings that engage in cavities in the caps. With high lateral rock pressure the concrete door frame is moved. This only results in a lateral shift of the passage cross-section, but no narrowing, and the load-bearing capacity is retained.
In der Zeichnung ist eine Ausführungsform des Betontürstockes als Beispiel dargestellt. Es zeigen:In the drawing, an embodiment of the concrete door frame is shown as an example. Show it:
Fig. ι eine Ansicht des ganzen Türstockes,Fig. Ι a view of the entire door frame,
Fig. 2 eine Seitenansicht des Stempels in Richtung des Pfeiles A und einen Querschnitt durch den darüberliegenden Teil der'Kappe,2 shows a side view of the stamp in the direction of arrow A and a cross section through the overlying part of the cap,
Fig. 3 einen Querschnitt nach B-C der Kappe in vergrößertem Maßstab.Fig. 3 is a cross-section after BC of the cap on an enlarged scale.
Das Ende ζ des Stempels s ist abgerundet und greift in die Höhlung z1 der Kappe k ein. Zweckmäßig ordnet man in den Höhlungen zwischen den Betonteilen zur Druckverteilung und Schonung eine Korkplatte ft an.The end ζ of the stamp s is rounded and engages in the cavity z 1 of the cap k . A cork plate ft is expediently arranged in the cavities between the concrete parts for pressure distribution and protection.
