Formwork assembly and stripping
If the walkway bracket was not
pre-assembled before step 1, you
can now assemble and install the
working platform. Fig. 64.2 on
page M350-64 shows a work-
ing platform being lifted with a
crane for attachment to a braced
outside formwork.
3. String further panels together
and connect them with M
assembly locks (see page
M350-7.
Panels with a height of 350 cm
are usually connected with three
assembly locks. However, outside
corner configurations require
four assembly locks (Fig. 63.2).
Step 2
Pouring height,
reinforcements and boxouts
After performing step 1, the
pouring height is defined and
marked. Then the reinforcements
and boxouts, if required, are
installed.
Step 3
Place the inside formwork
and tie the outside and inside
formwork
The inside formwork is placed
after the outside formwork. Then
the inside and outside formwork
are tied firmly with tie rods and
articulated flange nuts.
Step 1
Place and brace the outside
formwork
The following description is
based on an straight wall. Before
starting, keep in mind:
Æ
When pre-assembling large
panel units on an even surface,
attach the wall braces and the
walkway bracket as well, i.e.
before performing step 1.
Æ
Walls of less than 6 m
require a filler in the inside
formwork for easy stripping
(Fig. 63.3), as the formwork may
otherwise become wedged and
stick to the concrete when it is
stripped.
1. Spray the facing with the
release agent MevaTrenn FT8.
2. Place the first panel and
immediately attach it to the
ground or concrete slab with
two brace frames to prevent it
falling over (Fig. 63.1). The foot
plate must be firmly connected
to the ground or concrete slab –
in earth with two ground pegs,
in concrete with two heavy-duty
dowels.
After placing vertical panels,
always reinforce them imme-
diately with push-pull props or
brace frames so they can with-
stand tensile and compressive
forces and are protected against
displacement and wind. The prop
spacing is determined by the
application.
