Description
Nachgiebiger Türstockausbau Es ist eine bekannte Tatsache, claß der nachgiebige Grubenausbau im allgemeinen eine bedeutend längere Lebensdauer aufweist als der unnachgiebige. Ein bekanntes Mittel zur Erzielung einer gewissen Nachgiebigkeit ist das Einfügen von Ouetschhölzern zwischen dem Gebirge und dem Ausbau bz-%v. zwischen den einzelnen Teilen des Ausbaues. Man hat zu gleichem Zweck auch auf der Außenseite des Ausbaues Hohlkörper aus Beton oder Eisenbeton angeordnet, die bei zu hohem Gebirgsdruck zu Bruch gehen.Resilient door frame extension It is a known fact that it is compliant pit lining generally has a significantly longer service life than the unyielding. A well-known means of achieving some compliance is the insertion of Ouetsch woods between the mountains and the expansion or% v. between the individual parts of the expansion. One has on the outside for the same purpose the expansion hollow body made of concrete or reinforced concrete arranged, which is too high rock pressure to break.
Gemäß der Erfin.;lung wird ein nachgiebiger Ausbau dadurch erzielt, daß auf die Außenseiten der Stempel bzw. Kappen nachgiebige Körper aus Eisen aufgesetzt werden, die bei hohem Gebirgsdruck nicht brechen, sondern sich unter Widerstandsleistung allmählich zusammenpressen lassen. Die Hohlkörper sind beispielsweise aus Bandeisen U-förmig gebogen. Sie können an dem Kopfende eine Einbuchtung für die Aufnahme der Verzugsspitzen oder Bolzen tragen und an dem Fußende mit einer Platte zum Abstützen gegen Stempel versehen sein. Zweckmäßig werden jedoch mehrere derartiger Hohlkörper nebeneinander auf einer langen Leiste angeordnet, die evtl. der Außenseite des Stempels bzw. dem Kopfe der Stempel- oder Kappenschiene angepaßt ist. Dadurch wird das Einbauen der nachgiebigen Auflage wesentlich erleichtert.According to the invention, a flexible expansion is achieved by that resilient bodies made of iron are placed on the outside of the stamp or caps which do not break at high rock pressure, but rather under resistance power let it compress gradually. The hollow bodies are, for example, made of band iron Bent into a U-shape. You can find an indentation at the head end for receiving the Wear warping points or bolts and at the foot end with a plate for support be provided against stamp. However, several such hollow bodies are expedient arranged side by side on a long bar, possibly the outside of the stamp or is adapted to the head of the stamp or cap rail. This will make the paving the resilient support is much easier.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen Abb. t einen Türstock, Abb. 2 eine Seitenansicht desselben, Abb. 3 in vergrößertem :Maßstabe die Hohlkörper, Abb. 4 eine andere Ansicht eines Hohlkörpers.-Auf die Außenseiten der starr zu einem Türstock miteinander .verbundenen Stempelschienen a und Kappenschiene b sind die Hohlkörper c aus Blech aufgesetzt. Die einzelnen Hohlkörper sind aus Bandeisen U-förmig gebogen und an dem Kopfende mit einer, Einbuchtung d versehen, die zur Aufnahme der Verzugsbolzen f dient. Mehrere derartiger Hohlkörper c sind auf einer gemeisamen Fußleiste g aufgenietet, die der Form des Schienenkopfes 1s angepaßt ist. Insbesondere ist aus der Abb.2 zu ersehen, in welcher Weise die Verzugsbolzen hinter dem Stempel angeordnet sind. .An exemplary embodiment of the invention is shown in the drawing. Fig. T shows a door frame, Fig. 2 shows a side view of the same, Fig. 3 in enlarged: scale the hollow body, Fig. 4 another view of a hollow body the outside of the stamp rails, which are rigidly connected to one another to form a door frame a and cap rail b are placed on the hollow body c made of sheet metal. The single ones Hollow bodies are bent into a U-shape from band iron and have an indentation at the head end d, which serves to accommodate the delay bolt f. Several such hollow bodies c are riveted to a joint baseboard g, which has the shape of the rail head 1s is adjusted. In particular, it can be seen from Fig.2 in which way the Lag bolts are arranged behind the punch. .
