Description
Laschenartige Verbindung zweier zu einem bogenförmigen Rahmen zusammengesetzter Ausbauschienen Die Stoßstellen von zwei in Streckenausbau dienendeli Schienen durch kurze Laschen zu -übertragen, welche mittels Schrauben an den Schienen. befestigt werden, ist bekannt. An Stelle der Schrauben wurden auch. bereits Schellen zur Verbindung der kurzen Laschen mit den Schienen vorgeschlagen.Tab-like connection of two assembled to form an arched frame Expansion rails The joints of two rails in the route expansion are used short straps to transfer, which by means of screws on the rails. attached is known. In place of the screws were also. already clamps for connection the short lugs with the rails are suggested.
Zwecks Erhöhung der Festigkeit hufeisenförmiger Ausbauträger hat man diese bereits mit seitlich angeschraubten Verstärkungen, beispielsweise alten Grubenschienen, versehen.To increase the strength of horseshoe-shaped support girders these already with reinforcements screwed on at the side, for example old pit rails, Mistake.
Erfindungsgemäß wird bei kreisbogenförmigen Rahmen die Verlaschung so gestaltet, daß sie gleichzeitig zu einer Verstärkung des Ausbaubogens gegen den Gebirgsdruck auch an solchen Stellen herangezogen werden kann, welche außerhalb des Bereiches der zu vierlaschenden Stoßstelle liegen. Zu diesem Zweck wird die Lasche als an dem Rahmen längs verschiebbare Ausbauschiene ausgebildet, deren Länge die der bisher bekannten normalen Laschen um ein Mehrfaches übertrifft. Ihre Befestigung erfolgt mit Schellen an den Ausbauteilen derart, daß sie bei gelösten Schellen beliebig in ihrer Längsrichtung verschoben werden kann. Durch diese Anordnung ist die Möglichkeit gegeben, nicht nur die Stoßstelle zu überbrücken, sondern durch eine Längsverschiebung der Ausbauschiene letztere jeweils in eine solche Lage zubringen, in welcher sie dem bogenförmigen Streckenausbau die beste Verstärkung gegenüber örtlichen 'Gebirgsdrücken bietet.According to the invention, in the case of a circular arc-shaped frame, the lashing designed so that they simultaneously reinforce the expansion arch against the Rock pressure can also be used in such places, which are outside the area of the joint to be four-lashed. For this purpose, the Tab formed as a longitudinally displaceable extension rail on the frame, the length of which exceeds that of the previously known normal tabs many times over. Your attachment is carried out with clamps on the expansion parts in such a way that they can be used as desired when the clamps are loosened can be moved in its longitudinal direction. With this arrangement is the possibility given, not only to bridge the joint, but by a longitudinal shift the expansion rail bring the latter in such a position in which they the arch-shaped expansion of the route provides the best reinforcement against local mountain pressures offers.
In den Zeichnungen sind Ausführungsbeispiele dargestellt.Exemplary embodiments are shown in the drawings.
Fig. z zeigt einen Bogen in Ansicht und in größerem Maßstab einen Schnitt B-C durch die schellenartigen Klammern E. Es ist ersichtlich, daß die Ausbauschiene D nicht nur die Stoßstelle A überbrückt, sondern weit nach beiden Seiten übergreifend und durch weitere Klammern E' gehalten, eine wesentliche Verstärkung des Streckenbogens bildet.Fig. Z shows an arch in view and on a larger scale one Section B-C through the clamp-like brackets E. It can be seen that the expansion rail D not only bridges joint A, but extends far to both sides and held by further brackets E ', a substantial reinforcement of the route arc forms.
Fig.,z zeigt, wie durch Längsverschiebung der Ausbauschiene D diese zur Aufnahme aus beliebiger Richtung kommender Gebirgsdrücke verlagert werden kann. Im dargestellten Fall ist der Gebirgsdruck von rechts oben kommend aufzunehmen.Fig., Z shows how by longitudinal displacement of the expansion rail D this can be relocated to accommodate mountain pressures coming from any direction. In the case shown, the rock pressure is to be recorded coming from the top right.
