Abstract

Die Erfindung betrifft eine schaltbare Magnetvorrichtung (1) zum Befestigen einer Schalungseinrichtung (9) auf einer magnetisierbaren Schalungsunterlage (2), mit einer eine Magnetkraft erzeugenden Magneteinrichtung (10) und einer zumindest abschnittsweise magnetisierbaren Stützeinrichtung (20), über die sich die Magneteinrichtung bei auf der Schalungsunterlage aufgesetzter Magnetvorrichtung zumindest mittelbar an der Schalungsunterlage abstützt, wobei die Magnetvorrichtung zwischen einer ersten Stellung, in welcher die Stützeinrichtung die Magnetkraft auf die Schalungsunterlage überträgt, um die Magnetvorrichtung auf der Schalungsunterlage zu befestigen, und einer zweiten Stellung, in welcher die Übertragung der Magnetkraft zwischen der Magneteinrichtung und der Schalungsunterlage im Wesentlichen unterbrochen ist, so dass die Magnetvorrichtung von der Schalungsunterlage abhebbar ist, schaltbar ist.
