Pre-assembly of support frame units
The surface on which the form-
work and the support frames are
pre-assembled should be clean,
even and capable of supporting
the total weight. The support
frames are attached to the rear
of the horizontal formwork
panels (Fig. 12.1).
Assembly
Æ
The support frame is
attached to the formwork’s mul-
ti-function profiles using flange
screw 18. Alternatively, it can
be attached using the tie holes
of the formwork with fixing
screws 35 and articulated flange
nuts 15/120 or flange nuts 100.
The fixing screws must be in-
serted through the tie holes and
secured to prevent them falling
out, using the flange nut 100 for
example, before the formwork
panel is placed on the ground.
Æ
The height extensions are
bolted to the support frame or
height extension below using
the eight (8) M20x50 screws and
M20 nuts supplied.
Æ
The pre-assembled units
should rest on square timbers
(face down) on the ground be-
fore they are flown into place.
Assembly of the Triplex SB
braces
Depending on the overall height,
it may be necessary to attach
Triplex SB braces to the height
extensions 150 and the base
extensions. The fastening ele-
ments required are supplied with
the height and base extensions
(Figures 12.2 to 12.4).

Spindle
Attention
Æ
When using the STB unit
vertically, the spindle must be
set to the middle position before
mounting the STB on the form-
work. This ensures that it can
be perfectly adapted to suit the
supporting surface.
Æ
Before pouring, ensure that
all STB spindles and additional
braces are secure and contact
the ground.

nical Instruction Manual (www.
