Fig. 39.6

Figures 39.1 to 39.6 show
various options for connecting
formwork to an existing wall.
Depending on the wall layout
and conditions on the construc-
tion site, the most suitable solu-
tion may vary from case to case.

Always make sure the formwork
is firmly pressed up against the
existing wall and attached to it
without gaps in order to avoid
leakage of the fresh concrete and
a patchy concrete surface.

Wooden blocking

Existing tie hole

Drive nut 60 (DW 15)
or
Hexagonal nut (DW 20) U
washer 60/100

Attachment through
existing tie holes
