<p>A recess former (70) is disclosed for use with anchors (80) which are to be cast into a concrete slab. The recess former (70) preferably includes magnetic implants (76) a removable plug (83) and preferably rectangular lugs (75) which engage with corresponding apertures in the attachment head (81) of the lifting anchor and prevent the ingress of cement during casting of the slab. Preferably the former is pivoted between open and closed positions. Magnetic attraction between the magnetic implants (76) and the ferromagnetic anchor (80) prevents dislodgement of the anchor (80) from the recess former (70) and maintains mechanical engagement between the anchor (80), the plug (83), the lugs (75) and the body halves (71A and 71B) of the recess former (70). 51750-AU & NZ 76 75'76 84 90A, 90B 76 75' Fig. 12 Fig. 13 Fig. 14 Fig. 15 9hIIIr76 Fig. 16 Fig. 17</p> |
