Description

Die Erfindung bezieht sich auf Ouetschhölzer für den Grubenausbau, insbesondere für Grubenstempel. Als Quetschkörper werden hierbei Plättchen aus Holzbenutzt, die unter dem Gebirgsdruck zusammengedrückt werden. Nach dem Zusammendrücken sind sie nicht mehr verwendbar.The invention relates to Ouetsch woods for pit construction, especially for pit punches. Small plates made of wood are used as squeeze bodies, which are compressed under the mountain pressure. After squeezing are they can no longer be used.

Gemäß der Erfindung besteht der Quetschkörper aus abwechselnden Schichten von Metall und Gummi.According to the invention, the squeeze body consists of alternating layers of metal and rubber.

Die Erfindung ist 2n der Zeichnung beispielsweise dargestellt.The invention is illustrated in the drawing, for example.

Der Quetschkörper besteht aus abwechselnd aufeinandergelegten Schichten a aus Metall, vorzugsweise Stahl, und Schichten b aus Gummi, die an das Metall anvulkanisiert werden. Die Dicke der Gummischichten wird entsprechend dem aufzunehmenden Druck gewählt. Sie liegt z. B. in der Größenordnung von i mm.The squeeze body consists of alternating layers a made of metal, preferably steel, and layers b made of rubber which are vulcanized onto the metal will. The thickness of the rubber layers will be according to the pressure to be absorbed chosen. She is z. B. on the order of i mm.
