Abstract
Description
Ankerausbau mittels Anker und Kalottenplatten.Anchor extension using anchors and spherical plates.
Um den Grubenausbau im Bergbau zu entlasten bzw. zu verstärken, bringt man zusätzlich Anker mit Kalottenplatten an, die nach anzug der Ankerschraube einem gewissen Leil des Gebirges mehr Widerstand bietet. Diese Anker mit Kalottenplatte werden in der Regel vorzugsweise in den Zwischenabständen der einzelnen Grubenausbaue angebracht.In order to relieve or strengthen the mine expansion in mining, brings you also attach anchors with spherical plates, which after tightening the anchor screw a offers more resistance to certain parts of the mountains. These anchors with a dome plate are usually preferably placed in the intervals between the individual pit supports appropriate.
Die Kalottenplatte ist an sich ziemlich klein, besitzt dtirchschnittlich eine Größe von 200 x 200 rnm und weist verschiedene Stärken auf. Im Bereich dieser Kalottenplatte kommt somit das Gebirge insbesondere zinn Tragen.The calotte plate is actually quite small, has an average size a size of 200 x 200 mm and has different thicknesses. In the area of this The dome plate thus carries the mountains in particular tin.
Will man aber möglichst große Abschnitte zwischen den Bauen des Gebirges zum Tragen bringen, muß man je nach Größe und Abstand der Baue mehrere Anker anbringen, was in diesem Falle mehr Arbeit und Kosten bedingt.But if you want the largest possible sections between the buildings of the mountains to bring it to fruition, you have to attach several anchors depending on the size and distance of the structures, which in this case entails more work and costs.
Um die freien Zwischenrätune zu vermeiden, die trotzdem beim Ankern entstehen und ein IIereinbrechen des Gebirges ermöglichen, ist es vorteilhaft, nicht die kleinen Kalottenplatten sondern Bänder zu verwenden, die je nach Größe Stärke und Abstand der einzelnen Grubenausbaue diesen wusbauen angepaßt werden. Diese Längsplatten sind aber so bescharfen, daß sie an ihren Enden kalottenförmig ausgebildet und mit Langschlitzen versehen sind. Die Kalotte muß nicht unbedingt rund sein, sie kann mit länglichen Sicken und Langloch oder in ähnlicher Form ausgebildet sein. Sie müssen jedoch so gestaltet sein, daß die Kalotte oder Ausprägungen mit Langschlitz jeweils beim Setzen der Ankerausbaue ineinander passen. Die Längsschlitze haben den Vorteil, daß beim Bohren des Ankers kleinere Differenzen ausgeglichen werden können. Bringt man nun diese flattern, die sich im Bereich der Kalotte oder Ausprägungen überlappen, zwischen den Bauen mittels eines Ankers iln das ilangende an, so werden wesentlich größere Flächen des Gebirges erfaßt, wodurch ein Einbruch des Gebirges zwischen den Platten nicht mehr rnöglich ist.In order to avoid the free interim advice that is still necessary when anchoring arise and allow a collapse of the mountains, it is advantageous not the small domed plates but rather tapes to use, the thickness depending on the size and the spacing of the individual pit extensions can be adapted to these wusbuildings. These longitudinal plates but are so sharpened that they are dome-shaped at their ends and with Long slots are provided. The dome does not necessarily have to be round, it can be designed with elongated beads and elongated hole or in a similar shape. she have to however, be designed so that the dome or expressions with a long slot each when setting the anchor extensions fit into each other. The longitudinal slots have the advantage that small differences can be compensated for when drilling the anchor. Brings you now flutter these, which overlap in the area of the dome or features, between the buildings by means of an anchor in the long end, so become essential larger areas of the mountain range covered, causing a collapse of the mountain range between the plates are no longer possible.
hierdurch wird auch erreicht, daß man weniger Anker benötigt und ferner größere Flächen des Gebirges abgesichert sind. Die ilatten mit ihren kalotten werden dem jeweiligen Ausbau, ob Rundbau oder Türstockbau, angepaßt.this also ensures that fewer anchors are required and furthermore larger areas of the mountain are secured. The slats with their domes are adapted to the respective expansion, whether round building or door frame construction.
Ein Ausführungsbeispiel der Neuerung wird nachfolgend an Hand der Zeichnung erläutert.An exemplary embodiment of the innovation is given below with reference to the Drawing explained.
Die Zeichnung zeit dabei in Figg. 1) schaubildlich einen Ankerausbau mit länglichen Kalottenplatten, Figg. 2) Platten mit Ausbildung von Kalotten bzw.The drawing time in Figg. 1) shows an anchor extension with elongated spherical plates, Figg. 2) Plates with domes or
kalottenförmige Ausprägungen mit Längsschlitz. Dome-shaped features with a longitudinal slot.
In der Zeichnung Figg. 1 ist mit Q) eine Platte bezeichnet, die kalottenförmig ausgebildet ist. Ferner ist in Figg. 1 eine Überlappung a) verschiedener Kalottenplatten dargestellt.In the drawing Figg. 1, Q) denotes a plate which is dome-shaped is trained. Furthermore, in Fig. 1 an overlap a) different dome plates shown.
In der Zeichnung Figg. 2 sind verschiedene Ausführungsarten a) b) c) der Kalottenformen dargestellt.In the drawing Figg. 2 are different types a) b) c) the dome shapes shown.
Wie aus der Darstellung ohne weiters erkennbar, werden durch die neuerungsgemäße Vorrichtung beim Anbringen dieser länglichen Kalottenplatten beim Ankerausbau größere Plächen des Gebirges erfaßt, die wesentliche Vorteile gegenüber den normalen Kalottenplatten bieten.As can be seen from the representation without further notice, according to the innovation Device when attaching these elongated dome plates when expanding the anchor larger Plateaus of the mountain range are recorded, which have significant advantages over normal domed plates Offer.
