COMPONENT DESCRIPTIONS
STIFFENING BRACKET (CODE
INBRKT.X
4
)
Suitable for 25 to 50 cm crown spans (sheet profile), the components must be assembled (as explained in
detail in the next paragraph). The stiffening bracket can be integrated into a line to create a more rigid
system.
Every
INBRKT.X
4
bracket consists of:
• UPPER diagonal rib (Fig. 7).
• LOWER diagonal rib (Fig. 8).
The upper diagonal rib (Fig. 7) and the
lower diagonal (Fig. 8) differ by their
bending angle: to recognise them and
not invert them during assembly, the
complete device markings are given on
the upper diagonal rib, while only the
batch number on the lower diagonal rib.
• FIXING FEET (standard) (Fig. 9)
Interface for fixing on corrugated roofs
with permitted shapes and thicknesses,
using the rivets supplied, directly to the
profile crown of the sandwich panel or
corrugated sheet. The feet are already bent
at an internal angle of 120°, but they can
be ordered with different angles (the
internal angle that HARKEN can supply
remaining within the idea of standard
fixing feet is in the range of 90° / 150°): do
not tamper with or modify the finished
element supplied by HARKEN. 4 fixing feet
are required for each stiffening bracket.
• Rail/Bracket FIXING KIT (Fig. 10)
1 threaded insert INFIX1.LS.
1 screw M10x25 in A2/70.
1 washer for connection between the
diagonal ribs.
