Wall formwork

Mammut XT

The dimension y (Fig. 47.1),
which represents the gap
between the hinged outside
corner and the first double-sided
standard Mammut XT panel,
can either be calculated using
the adjacent formula or can be
determined using Table 47.2,
depending on the inside angle
and the wall thickness.

Height 300

If 300 cm high M hinged corners
are used, Mammut 350/Mammut
panels are to be used next to the
hinged outside corner.
