Use on circular structures
Parallel arrangement of brackets
Depending on bracket spacing c, brackets
can be positioned parallel to each other
as of a certain radius of the building.
Advantage:
The adjusting unit can be used for tilt-
ing the formwork.
The maximum twist in the scaffold
mounting ring is 5°. The pressure point
of the bracket is wedged to compen-
sate for the angle. (Fig. C1.17)
Requirements for the radius of the
building:
available R ≥ 5.72 x actual c
System statics are proved with the
application diagrams according to the
type test.

Disadvantage:
The tilting possibilities for the formwork
are limited.
Wedges for compensating the angle
have to be fitted between the girder
and mounting plate.
If the arc rise s of the building edge is
too big, the innermost girder must be
additionally moved outwards by means
of packing in order to provide sufficient
space between the girder and the
building. (Fig. C1.18)
The same applies to the finishing
platforms.
Special measures have to be undertak-
en if scaffold tube units are installed.
Static proof is to be carried out sepa-
rately.
