It has proven practical to secure the installation rail to
the upper reinforcement by wire.
HDB Elements can also be installed in
an inverted position in prefab slabs or
when the upper reinforcement is ex-
tremely congested. (Installation bar at
the bottom of the element). The full
load capacity of the HDB Shear rails is
also guaranteed in this position.
HALFEN Shear rails type HDB-F are
installed from above in prefab slabs.
See brochure “HALFEN HDB Punching
