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.
