A magnetic clamp for formwork

摘要

A magnetic clamp 10 for use in clamping metal formwork into position for precast concrete manufacture includes a housing 12, a magnet 14 that is displaceable within the housing, and a side-form connector 38 for connecting the housing to a side-form. An actuator 20 acting via a force amplification link mechanism 24, at least a portion of which is interposed between the actuator and the magnet, serves to move the magnet between a position in which it is disengaged from the formwork bed and an operative position in which the magnet is substantially fully in contact with the bed on which the clamp is mounted to clamp the side-form in position relative to the bed.
