Description
Nachgiebiger, eiserner Grubenausbau Es ist bekannt, in Strecken unter Tage einen eisernen, aus einzelnen Ausbauteilen bestehenden und durch Laschen miteinander verbundenen Ausbau einzubringen. Um diesen Ausbau nachgiebig zu gestalten, sind in die Laschen, die man aus diesem Grunde auch ausgebaucht hat, Quetschhölzer eingelegt worden. Da Quetschhölzer nur in beschränktem Maße nachgiebig sind, werden gemäß der Erfindung in den Laschen Stahlfedern angeordnet, die vorteilhaft so gelegt werden, daß zwei gegeneinander gerichtete Federn auf ein OOuetschholz drücken. Die Vorteile der Erfindung bestehen darin, daß sich der Ausbau sogleich nach dem Einbau gleichmäßig fest an das Gebirge anlegt, und darin, daß die Nachgiebigkeit des Ausbaues erhöht und unabhängig von der Zusammendrückbarkeit des Holzes gemacht wird.Resilient, iron pit lining It is known to take in stretches Days an iron one, consisting of individual parts and brackets with each other related expansion. To make this expansion flexible, are Squeezes are inserted into the flaps, which have also been bulged for this reason been. Since squeezes are only resilient to a limited extent, according to the invention arranged in the tabs steel springs, which are advantageously placed so that two springs directed against one another press on a wooden stick. The advantages of the invention consist in the fact that the expansion is evenly distributed immediately after installation firmly attached to the mountains, and in that the resilience of the expansion increases and is made independent of the compressibility of the wood.
In der Zeichnung ist eine Ausführungsform der Erfindung dargestellt. Es zeigen Fig. i einen Querschnitt durch eine Laschenverbindung, Fig. a eine Seitenansicht der Laschenverbindung, zum Teil im Schnitt, Fig. 3 einen Ausschnitt aus einem Profileisenausbau.In the drawing, an embodiment of the invention is shown. FIG. 1 shows a cross section through a tab connection, FIG. A shows a side view the tab connection, partly in section, FIG. 3 shows a detail from a profile iron construction.
Die segmentförmigen Profileisen a und a1 von j-förmigem Querschnitt werden durch die Laschen b und b; die Schrauben c und cl, die in einem Langauge f der Laschen beweglich angeordnet sind, miteinander verbunden. Die Laschen sind an der `Verbindungsstelle der zu verbindenden Teile derartig erweitert, daß ein Quetschholz-d und die Stahlfedern e und e1 eingelegt werden können, wodurch die Widerstandsfähigkeit, ohne die Nachgiebigkeit zu beeinträchtigen, erhöht, und der Ausbau sofort beim Einbau gegen Umfallen gesichert wird.The segment-shaped profile iron a and a1 of J-shaped cross-section are through the tabs b and b; the screws c and cl, which are in a long eye f of the tabs are movably arranged, connected to one another. The tabs are at the `junction of the parts to be connected expanded in such a way that a Quetschholz-d and the steel springs e and e1 can be inserted, whereby the Resilience without compromising resilience increases, and the Removal is secured against falling over immediately upon installation.
