When a heavy body of concrete is cast in a mould cavity (21), a filler member with a pair of jaws and a lifting anchor (17) held between the jaws of the filler member may be arranged within the cavity of the mould (21) through an opening (26) defined in a mould wall part. Stud-like connecting members (23) of a supporting device (22) received in bores defined in the filler member may move the jaws of the filler member between a closed position in which an outer end portion (18) is pinched between the jaws of the filler member and the connecting members of the supporting device (22) are interlocked with the filler member (10), and an open position, in which the stud-like connecting members (23) may be withdrawn from the filler member (10), for example when concrete has been poured into them and vibrated in the mould. |
