The M stripping corners 350
(Fig. 48.1), 300, 250 and 125
allow the formwork to be
removed safely and quickly from
poured shaft walls, for example,
without damaging the walls or
formwork. The stripping corners
work according to the “jumping
jack” principle.
The stripping corner is a three-
piece design to permit inward
movement.
The side length is 25 cm.
The height of the stripping
corner can be increased easily
(Fig. 48.1).
After pouring and when the
concrete has set sufficiently,
all stripping corners are acti-
vated (Fig. 48.2 and page
XT-52 to -54) and the entire
formwork can be lifted out of
the shaft as one single unit with
a 4-rope crane sling (Fig. 48.3).
There is no need to disassemble
the formwork. For details see
Figures 48.4 A and 48.5 B.
Note
Æ
The permissible load per
stripping corner is 10 kN (1 ton).
To calculate the permissible load,
assume that only two stripping
corners are used. The maximum
permissible total weight of the
complete shaft formwork is
thus 20 kN (2 tons). If the total
weight exceeds 20 kN (2 tons),
four M crane hooks with a
maximum total transport load

of 30 kN (3 tons) are to be used.
(Fig. 48.3). If the total weight ex-
ceeds 30 kN (3 tons), a transport
spreader must be used.
Æ
Before pouring, cover the
joints on the sides of the strip-
ping corner with adhesive tape
to make it easier to clean.
Æ
Make sure the entire form-
work is completely removed from
the poured walls before lifting it
by crane.
Height 300
If 300 cm high outside corners
are used, Mammut 350/Mammut
panels are to be used next to the
XT outside corner.
