on one point without casting directly against the
formwork.
 When casting with bucket, take special care of
not hitting the formwork, and of complying with
the maximum load-bearing capacity of the crane.
 Avoid concrete splashes on the plywood as these
will reflect on the finished surface.
 Use the appropriate method for concrete
consolidation and compaction depending on the
concrete consistency and its workability.
 The preferred consolidation and compaction
method for wet cast-in-place concrete are poker
vibrators. Use external vibrators only when the
concrete cannot be accessed with poker vibrators
and for parts moulded already in the workshop.
External vibration requires a specific analysis.
 Completely immerse the poker 10 to 15 cm into
the concrete, and put it into each area of
concrete, only once. When concrete is poured in
layers, place the vibrator into the previous layer to
meld the two layers together.
 Never allow the vibrator to touch the formwork to
prevent exceeding the considered loads.
 Immerse vertically or slightly inclined and quickly,
but withdraw slowly.
4.1.2.4 Concrete curing and formwork
stripping
 Check that curing is sufficiently advanced for
stripping without causing spalling at the concrete
surface which destroys the finishing and can
affect the strength and durability of the concrete.
 Increase the curing time of the concrete when
facing fast drying and shrinkage due to
evaporation from wind or low temperatures.
 The time span between casting and stripping shall
be the same for all parts of the concrete structure.
This is justified when a high finishing quality is
aimed for because the tone of the concrete
surface depends on how long the concrete
surface is isolated from the outside.
 Ensure the absence of unauthorised people in the
vicinity where stripping takes place.
1. Once stripping is finished, place the formwork on
a sort of support and proceed with its cleaning
and dismantling, if it is not going to be used for
further casts.
4.1.2.5 LIFTING BRACKET E V-100
 The LIFTING BRACKET E V-100 should be used in a
way it does not put in danger the integrity of
people.
 The LIFTING BRACKET E V-100 cannot be used in
applications not described in the User’s Guide.
 The LIFTING BRACKET E V-100 must be used only
to lift panels of the system ENKOFORM V-100. It
will never be used in other applications or with
other formwork systems.
 The LIFTING BRACKET E V-100 can only be used
to raise PANELS of the system ENKOFORM V-100
of ULMA. It will never be used for other
applications or other formwork systems.
 In case the LIFTING BRACKET E V-100 does not
work properly, it will have to be taken back
immediately to be repaired.

The LIFTING BRACKET E V-100 must not suffer
strong knocks and excessive crushing during its
handling, storage, transport and, mainly, when
shifting the PANEL from these BRACKETS.
 The LIFTING BRACKET E V-100 will remain in a
place protected from the atmospheric and
aggressive agents to avoid its deterioration.
 In case anyone who manipulates the LIFTING
BRACKET E V-100 notices any deterioration in it,
he/she will immediately take it back to have it
repaired.
