The insertion system is not suitable as assembly variant for the planned modules SOLON
M230/6+/07 (verification using the simplified procedure). Alternatively, another assembly
variant, thus optimal support of the modules, could be chosen (continue Item b) or the
extensive calculation procedure (Item c) used.
b) Assembly variant: optimum support and attachment

SOLON modules M230/6+/07 can therefore be installed, without the need for special
confirmation, using the altered assembly variant, that is with the optimum support
according to the assembly instructions.
Alternatively, the SOLON modules P180/6+ or
P130/6+ could be used with the insertion system too.
c) Assembly variant: Verification using the extensive calculation procedure
The
extensive
calculation
has
proven
that
the
SOLON
modules
can
also
be
used
with
the
insertion
system.
At
a
ground
elevation
above
sea
level
of
710
m,
the
calculated snow load on the ground is
s
k
= 3.95 kN/m²
instead
of
the
snow
load
on
the
ground
of
4.76
kN/m²
that
has
been
specified
by
the
table
for
800
m
(according
to
the
simplified
procedure,
the
snow
load
on
the
ground
had
to
be
selected
at
800).
Result:
s
kallow
= 4.50 kN/m² < s
k
= 3.95 kN/m²
As planned, the modules can also be installed using the insertion system!
