Suspensions
The uncovered threaded rods must be dimensioned such that
the calculated tension of 6 N/mm
2
is not exceeded (this ap-
plies to a max. length of 1.5 m). The suspending brackets
must be guided in U-shape around the duct (EN 13661).

thread to DIN 13, part 28

Note regarding steel dowels with general building supervi-
sory approval:
The suspending brackets must be fastened using expansion
dowels M8 made of steel. The dowels must be installed ac-
cording to the specifications of the valid approval notifica-
tions of the Institute of Structural Engineering and, in addi-
tion, the installation length must be twice as deep as required
in the approval notification unless stated otherwise in the ap-
proval notification; the calculated tensile load per dowel must
not exceed 500 N. Special dowels with a maximum tensile
load of 700 N can be also used.
