Description
Baukörper zum Ausbau von Schächten und Strecken Gegenstand der vorliegenden Erfindung ist eine weitere Ausgestaltung der in dem Patent 553 621 beschriebenen Ausführung der geschlossenen Holzkörper.Structures for the expansion of shafts and routes are the subject of the present The invention is another embodiment of that described in the '553,621 patent Execution of the closed wooden body.
Diese werden in der Weise hergestellt, daß in Rahmen oder Formen aus Flußstahlblech oder anderen Werkstoffen, die die für den jeweiligen Verwendungszweck geeignete Form erhalten, Holzklötze in der gewünschten Anzahl eingesetzt werden (s. a, Abb. I bis IV), und zwar zunächst so, daß die Holzfasern im wesentlichen parallel zu den Rahmenwandungen verlaufen. Zur Erhöhung des Widerstandes gegen Formveränderung des Ausbaues wird alsdann senkrecht zu diesen Hölzern eine weitere Lage Holzklötze eingebracht (s. b. Abb. I bis IV). Diese Hölzer werden mit den vorgenannten Holzklötzen d mit besonderen hierzu angefertigten Flußeisenkrampen starr verbunden (s. c, Abb: I bis IV). Alsdann werden die Hölzer durch einen oder mehrere Holz- oder Eisenkeile, die in die Querfugen eingetrieben werden, noch so weit zusammengepreßt, als es die Festigkeit des Rahmens zuläßt (s. d, Abb. I bis IV). Auf diese Weise besitzen also die Hölzer eine ganz bedeutende Vorpressung sowie einen erhöhten Druckwiderstand, so daß ein Ausbau mit solchen bewehrten Holzkörpern, wie in Abb. V dargestellt. dem Gebirgsdruck von vornherein einen noch größeren Widerstand gegen Formveränderung bietet.These are made in such a way that in frames or molds Mild steel sheet or other materials that are suitable for the respective purpose Get a suitable shape, insert the desired number of wooden blocks (see a, Fig. I to IV), initially in such a way that the wood fibers are essentially run parallel to the frame walls. To increase the resistance to change in shape During the expansion, another layer of wooden blocks is then placed perpendicular to these pieces of wood introduced (see fig. I to IV). These woods are made with the aforementioned wooden blocks d rigidly connected with special fluent iron staples made for this purpose (see c, fig: I to IV). Then the timbers are separated by one or more wooden or iron wedges, which are driven into the transverse joints, still compressed as far as the Strength of the frame allows (see d, Fig. I to IV). So own this way the timbers have a very significant pre-compression and increased pressure resistance, so that an extension with such reinforced wooden bodies, as shown in Fig. V. the rock pressure from the outset an even greater resistance to change in shape offers.
