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.

The invention relates to a switchable magnetic device (1) for fixing a formwork device (9) on a magnetizable formwork support (2), with a magnetic force generating magnetic means (10) and an at least partially magnetizable support means (20) via which the magnetic device at The magnetic device is supported between a first position in which the support means transmits the magnetic force to the formwork support to secure the magnetic device on the formwork support, and a second position in which the transmission of the magnetic force is substantially interrupted between the magnetic device and the shuttering pad, so that the magnetic device can be lifted from the shuttering pad, is switchable.
