NOTE:
Use this configuration only, if the distance between the concrete
and lower face of the false ceiling is
75mm – 175mm.
Calculating the length (L1) of the threaded rods:
c=distance from concrete ceiling to lower face of false ceiling;
must be measured!
Cut
L1 to c+20mm
/ Tolerance: +10mm/-0mm
Fig. 12
Cut each of the M16 threaded rods (1) to the length
L1 at one end only
.
Deburr to remove the sharp edges
at
the cut ends of the threaded rods.
After deburring, no visible chamfer should be present.
Make sure that
all threads
are
not damaged or dirty
.
Screw hexagon nuts (2) ca. 50mm onto
both
ends of each threaded rod (1).
Apply Loctite 270
to the uncut ends of the threaded rods.
Screw the uncut ends
of the threaded rods
fully
into the ceiling plate (3)
Secure each threaded rod with the preassembled hexagon nut to the ceiling
plate.
Make sure there’s still enough Loctite 270 on the rods for the nuts.
Fig. 13
Apply Loctite 270
to the lower ends of the threaded rods.
Push the
interface plate (4)
up to the required height on the threaded rods and
secure from beneath with
hexagon nuts (5)
.
Adjust the height and level alignment of the interface plate.
Tighten the hexagon nuts to the interface plate from above and below.
NOTE:
Every M16 hexagon nut
, including the ceiling plate securing
nuts, must be tightened with
200 Nm (±3%) torque
and secured
with
Loctite 270
!
After tightening,
mark every nut with
seal paint
from the nut to
the plate.
NOTE:
During installation, use a spirit level (accuracy: 1mm/m) to make
sure that the interface plate is horizontally aligned.
