Stabilising the flat roof supports
The following details refer to a single collector. These
details are based on DIN 1055, part 4 "Design loads for
buildings".
Individual flat roof supports may be secured in the follo-
wing three ways to prevent slippage or tipping of the
structure due to the effect of the wind:
—
Securing flat roof supports with anchor bolts (on-si-
te).
—
Weigh down flat roof supports with concrete slabs,
gravel or similar material (loading trays required).
—
Weigh down flat roof supports with concrete slabs,
gravel or similar material (loading trays required) and
make more secure using rope as necessary.
For all methods, please consider the structural integrity
of the roof.
USER NOTE
Using gravel in the loading trays, a maxi-
mum load of 320 kg is possible per collec-
tor (Tab. 8).
USER NOTE
For the following table, please also consi-
der the clearances and number of additio-
nal collector braces (Chapter 5.1
"Distances between collector braces for
on-site base anchoring").
