Triplex heavyduty braces must only be assembled and dis
assembled by persons with adequate working knowledge.
This manual illustrates the assembly and stripping
procedure of a standard application. For more complicated
or special applications not covered in this manual, please
contact the MEVA experts for advice.
All components have to be subjected to a visual check for
damages before assembly. Damaged parts must not be
used. The assembly sequence illustrated on the following
pages is binding.
Product Characteristics
Triplex is a heavyduty brace (three chords) to align and
brace formwork with heights exceeding 20‘ (6.00 m).
The system consits of modules which are assembled to the
required length on site. The standard components are:
intermediate pieces 300 cm (9‘10 1/8“), 200 cm (6‘6 3/4“),
100 cm (3‘3 3/8“) and 50 cm (1‘7 11/16“) as well as top
units with spindles.
The righthand and lefthand threads of the top units allow
for a precise adjustment.
Triplex is available in two different types:
Triplex R
is a brace for formwork heights of more than 20‘ (6.00 m).
It is attached to the formwork with a connector, and it is
provided with a foot plate to be anchored to the floor slab.
Triplex SB
is a reinforced version of the Triplex R brace (bigger
tubes). It is also used as an additional support for support
frames STB 450 with height extensions 150 when single
sided walls of more than 20‘ (6.00 m) are formed.

ContentsPlease note:
This technical manual contains information, instructions and
hints describing how to use the Triplex heavyduty braces on
the construction site in a proper, quick and economic way.
Most examples shown are standard applications as they
occur in practice most often. For more complicated or
special applications not covered in this manual, please
contact the MEVA experts for advice.
When using our products, the federal, state and local codes
and regulations must be observed.
The individual, projectrelated assembly instruction, which
has to be prepared onsite, serves to reduce the specific
jobsite risks and must contain the following information:
1. Sequence of operational procedures including assembly
and disassembly
2. Weight of individual components
3. Type, number and spacing of anchors and braces
4. Arrangement, number and dimension of access platforms
(working scaffolds) including the required fall protection
and walkways
5. Attachment points to allow transport by crane
For this, please adhere to the following technical
instructions when applying the Triplex system. Deviations
require engineering calculation and analysis for proper
safety.
Generally, only wellmaintained material may be used.
Damaged parts must be replaced. Apply only original MEVA
spare parts for replacement.

The formworkprop
connector is attached
to the formwork panel
by using a flange
screw, while the panel
is still lying on ground.
The Triplex R brace
is attached to the

The panels with braces
can be lifted to an
upright position by
using the MEVA crane
hook and 2rope crane
slings (Fig. 7.2).
Make sure to secure
the Triplex braces
safely to the floor slab
or concrete blocks
(dead man) with
adequate dowels or
the like, before you
detach the crane
slings.

Stripping
Fig. 12.1
Fig. 12.2
We recommend the
stripping of complete
units (Triplex braces
plus formwork).
After these units are
put to ground, the
Triplex braces can be
dismantled (Fig. 12.1).
Attach the 2rope
crane slings to one of
the chords of a Triplex
brace and remove
all connecting parts.
Then lift the Triplex
brace by crane and
put it aside for clean
ing or stacking
(Fig. 12.2).
Dirt is removed with
a brush or a cloth.
When cleaning the
Triplex braces, do not
use tools which might
cause scratches, and
do not hit the braces
with any tool.

Storage
The components of
the Triplex braces are
stored in stacking
racks, which can be
moved by crane or lift
truck. When a lift truck
is used, slide in the
forks from the long
side (parallel to the
short side) of the
stacking rack (Fig. 13.1
to 13.6).
Transport units per
stacking rack:
20 x R 50 507.1 lbs
17 x R 100 599.7 lbs
10 x R 200 573.2 lbs
10 x R 300 749.6 lbs

17 x SB 100 826.7 lbs
10 x SB 200 815.7 lbs
10 x SB 300 1,146.4 lbs
The top units 48 and
73 as well as the foot
plates 48 and 73 are
stored and delivered in
storage boxes
(Fig. 13.6).
Depending on the
total weight, either
three stacking racks or
three storage boxes
can be put upon each
other on a truck
(Fig. 13.5 and 13.6).

Rentals
We offer our customers
the option of renting
supplementary material
during peak times. We
also give prospective
customers the chance
to test MEVA formwork
so they can see its
benefits for themselves
in actual use.
RentalPlus
Since MEVA started the
flat rate for cleaning
and repair of rented
formwork systems in
early 2000 more and
more contractors expe-
rience the outstanding
advantages. Ask our
representatives about
the details!
Formwork drawings
Of course, all offices in
our technical depart
ment have CAD facili
ties. You get expert,
clearly represented
plans and work cycle
drawings.
MBS - MEVA Basic
Support
MBS is an addition to
AutoCAD, developed
by MEVA Formwork
Systems in 2000.
MBS is based on
standard programs
(AutoCAD and Excel)
and can be used on
any PC that has these
two programs installed.
It includes pull down
menues for AutoCAD
and applications to
ease forming. It also
includes the possibility
to create takeoffs
Special solutions
We can help with
special parts, custom
designed for your
project, as a supple
ment to our form
work systems.
Static calculations
Generally, this is
only necessary
for applications
like singlesided
formwork where
the anchor parts are
embedded in the
foundation or the
base slab. If request
ed, we can perform
static calculations for
such applications at
an additional charge.
