3.1.2.
Walers positioning
Once the brackets are assembled on the walers, the
next operation consists of positioning the walers. In
order to do it properly, some timber planks should be
used to support the set, preventing the Gravity pawl
from touching the floor. In this operation, walers are
spaced following the assembly drawings and
diagonals are measured to avoid making a
parallelepiped shape.
3.1.3.
Secondary beams positioning
Timber beams VM
Once the walers are positioned, secondary beams are
fixed on them using the RVM20 2T clamp. The beams
placed on the gravity pawls are directly screwed to
them using screws (5x30 screw); (detail A).
HM beams
If HM beams are used as secondary beams, the way of
placing them is the same as for VM beams, but in this
case it is necessary to keep in mind that is not possible
to assemble these beams on the Gravity pawl. The end
HM beams should be replaced by 5x15 planks.
The planks are fixed to the Gravity pawls using screws
in the same way as for the VM beams.
3.1.4.
Lifting chains assembly
In case platform and formwork have to be lifted
together, it is required to assemble lifting chains.
