Auxiliary tool, i.e. reinforcement bar
4. Installation with Steel recess former
In those cases where the precast unit
has to be lifted out of the mould
without having access to the recess
former, steel recess formers are used.
Two fi xing versions are available:
- for fastening with fi xing bolts
(steel or timber mould) and
- for magnetic fastening to steel
moulds, where holes cannot
be drilled.
If this type of former is used to position
the anchor horizontally within the
formwork, provisions should be taken
to prevent the anchor from becoming
dislodged when pouring the concrete
(e.g. by fi xing it to the reinforcement or
securing it with spacers).
After removing the mould the rubber
grommet is separated from the
cast-in HALFEN DEHA lifting anchor.

From above into the fresh concrete
2.1
If installation is from above after casting the fresh concrete, the recess former
together with the pre-assembled HALFEN DEHA Spherical head anchor is
inserted at the specifi ed position by pushing and lightly rocking the recess
former until its top edge is fl ush with the concrete surface. Using formwork
lubricant, particularly in the inner of the recess former, is benefi cial when
stripping the formwork, and to improve the lifespan of the recess former.
