1. Selecting the components
HALFEN Dowel restraint fi xings are used for transmitting
the shear loads in stacked precast concrete panel elements.
Each installation point consist of the following components;
1.1 Stainless steel dowel
1.2 Socket for casting into the upper façade panel
1.3 Socket for casting into the lower façade panel
1.4 Spiral reinforcement
(recommended with all plastic sockets to avoid
spalling)
1.1 Dowels in stainless steel

2. Fixing to the formwork
Refer to the engineers formwork and reinforcement plans
for the exact position of the sockets. Using this information
install and fi x the sockets with nails or other ancillary-aids
to secure to the precast formwork. The sockets must be
installed with care so that they are not misaligned or
inadequately fi xed! The long edge of the slotted sockets is
installed parallel to the designated fi nished concrete face
(usually the bottom of the formwork).
Do not use concrete vibrators near dowel restraint
fi xings!
3. Preparations

The recess former must be removed fi rst when using the
HFV 4 Grouting socket .
The HFV 4 and HFV 9 Grouting sockets must be fi lled with
mortar before panel assembly
mortar which has at least the same strength class as the
concrete of the façade panel.
