LOADING CONDITIONS
Bracing and tying-in
Vertical diagonal bracing between
the outside standards must be
installed in every 5th bay and always
in the end bays. SKRD guardrail
frames can replace vertical diagonal
braces, but must then be fitted in each
bay and at every lift level, including
the bottom level.
Plan braces must be fitted in every
5th bay and always in the end bays
at every 12th metre in height.
Each inside standard must be tied
to the facade or equivalent at every
4th metre in height adjacent to the
node between standard and beam.
The lowest tie must be fitted no more
than 4.8 m above ground level. There
must be ties that can carry horizontal
forces on at least every 5th pair of
standards along the scaffold and at
every level of ties.
In addition, we recommend that the
scaffold always be anchored as high
up as possible.
Where there are brackets, the
scaffold must be anchored at the level
of the brackets.
Scaffold with lattice beams must be
anchored at the fixing points of the
beams.
The following estimated maximum
loads apply to scaffolding of this
type of 24 m in height in accordance
with EN 12811. Ties that can
withstand horizontal forces should
be dimensioned for a load of 4.7 kN
parallel with the façade and 5.7 kN
perpendicular to the façade. Other
ties should be dimensioned for a
load of 3.9 kN perpendicular to the
façade.
Where a scaffold is covered in
sheeting, the number of ties must be
increased to take account of wind
load. Seperate calculations are
therefore required.
