Description

Bei den bisher vorhandenen Ausbauarten wird die Nachgiebigkeit durch Keile oder Verschraubungen geregelt, wobei das Nachgeben von dem sorgfältigen Setzen der einzelnen Baue und der Cberwachung abhängig ist. Nachgiebige Ausbauformen, die durch Holzeinlagen die Nachgiebigkeit erhalten, finden in der Stärke der Holzeinlagen eine Begrenzung.In the previously existing types of expansion, the compliance is through Wedges or screw connections regulated, the yielding from careful setting of the individual structures and the monitoring is dependent. Flexible structures that The flexibility obtained through wooden inlays can be found in the strength of the wooden inlays a limit.

Der in Abb. i der Zeichnung dargestellte erfindungsgemäße vierteilige Ausbau besteht aus zwei Bogensegmenten, zwei Ausbauunterteilen und einer Firstenverbindung. Das Bogensegment i, welches in dem Ausbauunterteil z eine Führung erhält, schiebt bei zunehmendem Druck ein unter dem Fuße befindliches Metallstück 4 auf mehrere Gleitschienen 3. Die Gleitschienen 3 tragen in der höchsten Stellung das Metallstück 4 und damit das Bogensegment i bis zu einem vorher festgelegten Gebirgsdruck. Bei zunehmendem Gebirgsdruck zerschneiden die nach unten konisch verlaufenden Gleitschienen das weiche Metallstück und setzen dem Bogensegment einen bestimmten Widerstand entgegen. Nach Beendigung der Nachgiebigkeit und nach dem späteren Rauben des Ausbaues kann derselbe durch Erneuerung des zerschnittenen und unbrauchbar gewordenen Metallstückes wieder in die Ausgangsstellung gebracht und damit neu verwendet werden.The four-part according to the invention shown in Fig. I of the drawing The extension consists of two arch segments, two extension parts and a roof connection. The arc segment i, which receives a guide in the expansion lower part z, pushes with increasing pressure one metal piece 4 located under the foot to several Slide rails 3. The slide rails 3 carry the metal piece in the highest position 4 and thus the arc segment i up to a previously determined rock pressure. at increasing rock pressure cut the downwardly conical slide rails the soft piece of metal and oppose a certain resistance to the arch segment. After the end of the yield and after the later robbery of the expansion can the same by renewing the cut and unusable piece of metal be brought back into the starting position and thus re-used.

Abb. a stellt die Ausbausegmente in zwei Längsschnitten und dem O_uerschnitt A-B dar.Fig. A shows the expansion segments in two longitudinal sections and the outer section A-B represent.

Der vorbeschriebene Ausbau findet für Abbaustrecken, Richtstrecken und Querschläge Verwendung.The expansion described above takes place for mining routes, straightening routes and ricochets use.

Die Vorteile des Ausbaues nach der Erfindung liegen darin, daß i. sämtliche Baue die gleich große Nachgiebigkeit besitzen und nicht von der Sorgfalt beim Setzen abhängig sind, a. Einsatzpunkt und Umfang der Nachgiebigkeit den Druckverhältnissen entsprechend festgelegt werden können, 3. alle hintereinandergesetzten Baue die Gebirgslast gleichmäßig tragen und das Gebirge sich gleichmäßig setzen kann, wodurch Deformierungen im Bogenprofil vermieden werden, 4. durch die große Nachgiebigkeit das Einbringen eines zweiten Ausbaues vermieden wird, 5. nach dem Rauben der Baue diese durch Einbau eines neuen Metallstückes erneut zum Einsatz gelangen können.The advantages of the expansion according to the invention are that i. all structures that have the same level of flexibility and not care are dependent on setting, a. The point of application and extent of the resilience to the pressure conditions can be determined accordingly, 3. all consecutive buildings the Carry the mountain load evenly and the mountains can settle evenly, whereby Deformations in the arch profile are avoided, 4. due to the great flexibility the introduction of a second extension is avoided, 5. after the structures have been looted these can be used again by installing a new piece of metal.
