Abstract (en)
[origin: WO2020097649A1] The invention relates to a device for retaining a lifting anchor (6) for a workpiece made of concrete during the vibration compacting of the concrete introduced into a mould for the production of the workpiece, comprising a frame (2) provided on a mould wall (1), which has an accommodating means (4) for the anchor head (10) of the lifting anchor (6) which can be moved by means of an actuator (12), transverse to the mould wall (1), between a working position and a release position, and which, in the working position of the accommodating means (4), penetrates a mould protrusion (7) closing an opening (8) in the mould wall (1) and forming a recess (9) in the workpiece, and comprising an electromagnet (13) provided in the accommodating means (4), arranged coaxially relative to the lifting anchor (6) and magnetically securing the anchor head (10) on the end side. In order to ensure advantageous release conditions, according to the invention, the core (14) of the electromagnet (13) forms a sliding guide for an ejector (16) striking the anchor head (10) on the end side and connected to an actuator (17).
