HALFEN offers two different systems for anchoring the facing layer
of sandwich panels to the supporting shell:
SPA sandwich panel anchors and FA flat anchors. In both systems the
support armature assume the function of transferring the dead
weight of the front panel, and a proportion of horizontal forces
from the effects of wind and temperature into the base
course.
Two FA support anchors are usually enough for
this.
If using two FA anchors, they should be symmetrical to the
fulcrum in every direction. Another bearing anchor should be
inserted as a horizontal anchor, perpendicular to the main
direction of the load.
Additional, officially approved connector pins and/or connector
brackets or clip-on pins are installed in the remaining area of the
plate to transfer the horizontal forces and prevent the facing
layer from warping.
When properly arranged, they minimise the constraining forces
caused by from thermal expansion and warping of the facing layer
through the construction of the FA anchor.
Through the round holes in the anchor ends the FA can be securely
tied to the existing reinforcement before pouring in the concrete,
by using reinforcing steel sections.
