Description

ßetonformstein für ringfötmigen Grubenausbau Für den ringförmigen Ausbau von Grubenräumen und Schachtausbauten sind verschiedene Formen von Betonformsteinen bekannt geworden, die Jedoch bei stärkerem Gebirgsdruck den an sie gestellten Anforderungen nur mehr oder weniger genügten.Concrete shaped stone for ring-shaped pit lining For ring-shaped Extension of pit rooms and shaft extensions are different forms of concrete blocks become known, but with stronger rock pressure the demands placed on them just more or less enough.

Erfindungsgemäß ist der Formstein für den ringförmigen Ausbau so geformt, daß dessen Radialfugenflächen gelenkartig durch Wölbung und entsprechende Höhlung ineinandergreifen; außerdem bildet der Querschnitt des Radialsteins in der Ausbauachsrichtung ein Parallelogramm, so daß seine Ringsegmentflächen spitzwinklig zur Ausbauachse verlaufen. Hierdurch wird ein Herausdrücken einzelner Steine, wie es bei den jetzt gebräuchlichen Formsteinen möglich ist, verhindert und infolgedessen der Zusammenhang der einzelnen Ringe unter allen Umständen gewahrt. Auch wird durch die spitzwinklig zur Ausbauachse durch die Parallelogrammform der Steine gebildeten Fugen erreicht, daß bei Gebirgsdruck nicht der einzelne Ausbauring diesen Druck auszuhalten hat, sondern ihn auch auf die Nachbarringe überträgt.According to the invention, the shaped stone for the annular expansion is shaped so that its radial joint surfaces articulated by arching and corresponding cavity interlock; also forms the cross-section of the radial stone in the axis direction of the expansion a parallelogram so that its ring segment surfaces are at an acute angle to the expansion axis get lost. This results in individual stones being pushed out, as is the case with the now common shaped stones is possible, and consequently the connection is prevented of the individual rings preserved under all circumstances. Also is due to the acute angled to the expansion axis achieved by the parallelogram shape of the stones joints, that the individual support ring does not have to withstand this pressure when the rock is under pressure, but also transfers it to the neighboring rings.
