Description
Geschlossener Eisenbeton-Streckenausbau Die Erfindung bezieht sich auf einen geschlossenen Eisenbeton-Streckenausbau aus in der Umfangsrichtung unterteilten Ringen mit zylindrischem Innenmantel, die gegenseitig in der Streckenlängsrichtung mit zum Innenmantel gleichachsigkreisförmigangeordnetenFührungen ineinandergreifen.Closed reinforced concrete route support The invention relates on a closed reinforced concrete route extension from subdivided in the circumferential direction Rings with a cylindrical inner jacket, mutually aligned in the longitudinal direction of the route mesh with guides arranged in the same axis as the inner jacket.
Das Neue besteht darin, daß der Außenmantel der Ringe elliptischen oder annähernd elliptischen Querschnitt hat und die Ringe unter Erhaltung einer glatten Innenwandung des Gesamtausbaues nach Maßgabe der mutmaßlichen Richtung - des Gebirgsdruckes in den einzelnen Längsabschnitten um die Streckenachse gegeneinander verdreht eingebaut werden.The novelty is that the outer surface of the rings is elliptical or approximately elliptical cross-section and the rings while maintaining a smooth inner wall of the overall construction according to the presumed direction - of the rock pressure in the individual longitudinal sections around the route axis against each other installed twisted.
In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt, und zwar zeigen Abb. i einen geschlossenen Streckenausbau in Stirn- und Innenansicht, Abb. a die Innenansicht eines Eisenbetonformstückes, Abb. 3 eine freiliegende Strecke, bei der die Ringe um die Streckenachse gegeneinander verdreht sind.In the drawing, the subject matter of the invention is in one embodiment shown, namely Fig.i show a closed track extension in front and interior view, Fig. a the interior view of a reinforced concrete molding, Fig. 3 a Exposed route in which the rings are twisted against each other around the route axis are.
Der Streckenausbau besteht aus Eisenbetonformstücken a und b, die sich zu Ringen zusammensetzen lassen, die einen kreisrunden inneren und einen ellipsenförmigen oder annähernd ellipsenförmigen äußeren Querschnitt haben. Nach der Zeichnung bilden die Formstücke a und b gleich lange und gleich breite Segmente mit im Winkel von 9o ° zueinanderstehenden Stoßfugen c. f e zwei Stücke a und zwei Stücke b bilden zusammen einen Ring. An den Stoßfugen c der Segmente sind Hohlkehlen d angebracht, die zur Aufnahme von Quetschhölzern e dienen, durch die den Ringen und damit dem Gesamtausbau Nachgiebigkeit verliehen wird. Die Stoßfugen f der Ringe greifen wiederum mit zum Innenmantel gleichachsig kreisförmig angeordneten Führungen g, h ineinander, so daß die Ringe beliebig um die Streckenachse gegeneinander verdreht werden können. Letzteres hat den Zweck, die Ellipsen der einzelnen Ringe so zueinander zu versetzen, daß ihr großer Durchmesser in der Richtung des Gebirgsdruckes verläuft und damit der stärkste Teil des Ringes dem Gebirgsdruck entgegengestellt werden kann. Dem Ausbau kann also, ohne die innere Zylinderform der Strecke zu verändern, am äußeren Umfange Torsion in beliebiger Richtung gegeben werden, und zwar so, wie es der Gebirgsdruck in den einzelnen Längsabschnitten einer Strecke vorschreibt.The extension consists of reinforced concrete fittings a and b, the can be put together to form rings, one circular inner and one elliptical or have approximately elliptical outer cross-section. Form according to the drawing the fittings a and b equally long and equally wide segments with at an angle of 90 ° butt joints c. f e form two pieces a and two pieces b together a ring. At the butt joints c of the segments there are fillets d, which serve to accommodate the squeezes e, through which the rings and thus the Overall expansion is given compliance. The butt joints f of the rings engage in turn with guides g, h arranged in a circle on the same axis as the inner jacket, so that the rings can be rotated against each other around the line axis. The purpose of the latter is to offset the ellipses of the individual rings from one another in such a way that that their large diameter runs in the direction of the rock pressure and thus the strongest part of the ring can be opposed to the mountain pressure. To the Expansion can therefore be carried out on the outside without changing the inner cylindrical shape of the route Extent torsion can be given in any direction, as it is the rock pressure in the individual longitudinal sections of a route.
