MammutXT inside corner
MammutXT panel w = 25 cm
M alignment rail 75
Single-sided tying
For single-sided tying at the
corner a 25 mm wide XT panel
is installed next to the XT inside
corner and next to the XT panel
opposite (50 or 75cm wide)
(Figures40.1 to 40.4).
For stabilisation, an M alignment
rail75 is fitted to the multi-
function profile of the panel
across the 25 cm wide panel
(Figures40.1 and 40.2).
The number of alignment rails
depends on the number of tie
holes in the panel.
For pouring heights up to
350cm and wall thicknesses up
to 30cm the M alignment rail is
not required (Figures.40.3 and
40.4 and Table4444.6).
Attention
Unused tie holes must always
be closed with plug D35/38 or
alternatively with XT sealing cone
(10) with a pressed-on plugD20
(see page XT-18).

Besides central tie holes, the 50

anchor sleeves in the frame.
These allow two-sided tying at
the corners (Figures41.2 and

90° corner – Inside corner
The MammutXT inside corner
is galvanised and has an alkus
all-plastic facing.
The inside corner (Fig.42.1) has
tie holes. Only three assembly
locks per joint are required for
height 350cm, all other heights
require two assembly locks per
side. The side length is 35 cm
(Fig.42.2) or 40cm (Fig.42.3),
see page XT-38.
Inside corner
with wood filler
The connection is achieved
with three Uni- or RS-assembly
locks for height 350cm and
with two assembly locks for all
other heights. For stabilisation,
an cross stiffener 44 must be
attached with a flange screw18
to the multifunction profiles at
each tie hole level (Fig.42.4).

90° corner – Outside corner
Fig. 43.1
The MammutXT outside corners
0, 10 and 15 (Fig.43.3) together
with the Mammut XT panels and
the M assembly lock result in a
solid 90° outside corner solution
(Figures43.1 and 43.2 and page
XT-38).
For the number of M assembly
locks required for a MammutXT
outside corner (a), for the next
panel joint (b) as well as for the
standard panel joint (c) refer to
Table43.6. This applies to both
single-sided (Fig.43.1) and two-
sided tying (Fig.43.2) in the cor-
ner area. For the assembly locks
and alignment rails required for
height-extended outside corners
refer to page XT-45).
Instead of using the MammutXT
outside corner, two MammutXT
panels can be butt jointed. In this
case, the panels are then bolted
together using M outside corner
brackets and flange screws 18
(Fig.43.5). Refer to Table 43.7
for the number of M outside
corner brackets required.

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 suciently,
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
ÆThe 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
Stripping corner
Fig. 48.2
Fig. 48.3
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.
ÆBefore pouring, cover the
joints on the sides of the strip-
ping corner with adhesive tape
to make it easier to clean.
ÆMake 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.

and panels (see pages XT-49
to -51).
3. Remove the wedges after
pouring and prior to stripping.
4. Activate the stripping corner
with a crowbar. The bell-crank
lever is pushed upwards using
the crowbar. The crowbar can be
applied at the bottom at position
A (Fig.52.3) or in the middle at
position B (Fig.52.4). This breaks
the bond between the formwork
facing and the concrete without
much effort.
Pages XT-53 and -54
describe how to activate the
stripping corner with the strip-
ping support.
5. Attach the stripping corners
with crane slings to the crane
gear. Make sure the entire form-
work is completely removed from
the poured walls before lifting it
by crane.
6. The entire formwork is moved
in one single lift and detached
from the crane when it is in its
new position.
7. The stripping corner can be
reset for the next pour by posi-
tioning the crowbar at position
C (Fig.52.5) and pushing the
bell-crank lever down.
8. Reinsert the wedge into the
connecting device (Fig.52.6).
9. A few hammer blows to the
wedge will move the lateral parts
of the stripping corner outwards
and keep them in the pouring
position.
Height extension
Two stripping corners can be
connected to each other easily by
joining their bell-crank levers. The
integrated pin must be secured
with the cotter pin (Position D,
Fig.52.1).

Stripping support
The stripping support (Fig.53.1)
is used to easily activate the
stripping corner from above
with a power screwdriver, a
ratchet spanner or a spanner.
Tools with width across flats of
27, 30 or 36 mm are to be used.
Assembly
1. Place the stripping support
onto the connecting device at
the top of the stripping corner.
Make sure the suspension is
inclined downwards (Fig.53.2).
2. Connect the stripping support
to the stripping corner with the
head bolt 16/40 and cotter pin 4
that are both integrated into the
tensioning screw of the stripping
support (Fig.53.2).
3. Lock the stripping support to
the stripping corner by driving
the stripping corner’s wedge
with a few hammer blows into
the opening of the stripping sup-
port (Fig.53.2).

Working principle of the
stripping support
The stripping support has three
hexagonal nuts that are operated
with tools with width across flats
of 27, 30 and 36 mm.
Turning the hexagonal nut on
the tensioning screw with a
power screwdriver (Fig.54.1),
a ratchet spanner (Fig.54.2) or
a spanner moves the bell-crank
lever upwards.
This activates the stripping
corner and separates the shaft
formwork from the poured walls
(Fig.54.4).

Stripping corner
The M stripping corner can also
be used as a stripping support
for panels between corners
inside a room. In this case,
the stripping corner is used to
reduce the tension between the
panels so that they can easily be
removed from the poured wall
between the corners.
Stripping procedure
1. Remove the M assembly locks
connecting the stripping corners
to the panels (Fig.55.1).
2. Activate the M stripping cor-
ner (Fig.55.2 and pages XT-52
to -54).
3. Lift the stripping corners off,
then strip the panels (Fig.55.3).

Length compensation – Mammut XT compensation panel
Fig. 56.1
Gaps of 20 to 50cm can be
compensated for with the Mam-
mutXT compensation panel.
The compensation panel con-
sists of two frame profiles with
integrated nailing strip. The
facing for the length compensa-
tion must be ordered separately
in the required width and height.
The facing must be 20mm thick.
We recommend using an alkus
facing AL20.
If the gap is greater than 30cm,
the compensation panel is sup-
ported in the middle with, for
example, square timber and tied
from both sides (Fig.56.1).
To stiffen the compensation
panel, alignment rails with flange
screw18 must be attached. The
minimum number of alignment
rails depends on the number of
tie holes / panel height (Fig-
ures56.1 to 56.4).

Gaps up to 10cm can be filled
on-site using timber fillers and
Uni-assembly locks 22, while for
gaps up to 16cm timber fillers
and Uni-assembly locks 28 are
used. The compensation areas
are reinforced with alignment
rails, which must always be
attached to the panels’ multi-
function profiles (Fig.57.1).
Timber profile
Timber profiles are used for gaps
exceeding 17cm (Figures57.2
and 57.3). A facing is cut to
size and attached to the timber
profiles. For stabilisation, align-
ment rails with flange nuts are
to be attached at the tie hole
(Fig.57.4) or to the multi-func-
tion profile. The minimum num-
ber of alignment rails depends
on the number of tie holes /
panel height.
For problem areas, job-built
formwork is attached to the pan-
els using M timber profiles and
M assembly locks (Figures. 57.3
and 57.4).
