Triplex heavyduty 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 heavyduty 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 righthand and lefthand 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 heavyduty 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, projectrelated assembly instruction, which
has to be prepared onsite, 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 wellmaintained material may be used.
Damaged parts must be replaced. Apply only original MEVA
spare parts for replacement.

Attachment of
Triplex R braces to
wall formwork
The formworkprop
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
connector by means of

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.
