MonoFix - Monolithic Formwork System

The MEVA MonoFix hand-set system is perfect for all residential construction projects thanks to its outstanding features: easy and quick assembly, cost-effective implementation on site and flexibility to adapt to any building layout.

Typical application

Slab panels assembly is started from the corner section of the slab. Subsequently, the whole slab area is filled by pinning the slab panels to the link beams (composed of end and middle beams).

Upon completion of the installation and fixing of the wall and slab panels, a numbering sequence is prepared for each of these panels. All ties, pins & wedges must be properly installed and secured before pouring concrete into the forms. The poured concrete should be distributed evenly throughout the wall panel section before passing to the slab.

Efficiency of MonoFix

Reliable, durable and reusable The wall panels are made of aluminum for a superior finish.

The vertical panel standard size is 245 cm high (look at panel range down). The special panels can range from a minimum of 10 cm to a maximum height of 300 cm and are available in widths ranging from 30 cm to 60 cm to match the building geometry. A wedge and pin arrangement guarantees a tight and perfectly aligned panel connection. Panels with perforated profiles can be manufactured to suit different column sizes.

One system for all parts of a building

The MEVA MonoFix system can be used to form all concrete structures:

  • Walls
  • Floors
  • Slabs
  • Balconies
  • Window hoods and parapets
  • Curved and decorative features
  • Columns
  • Beams
  • Stairs

Column and Beam Solution

Many residential projects require mainly walls and slabs, for which MonoFix is ideally suited. But even when projects require columns and beams rather than walls the MEVA MonoFix system can easily produce all sizes and connections of columns and beams needed - including complicated offsets and drop-panels. The system can be adapted to the beams or slabs according to the requirements of the project.

 

 

Stairs

The MonoFix monolithic system comes with integrated stair forms.

Stair forms are connected to the side wall panels and supported by MEVA props. They guarantee the correct geometry of the finished stairs and can be poured together with the walls and slabs above or in a second stage pour. Customized production of the stair forms allows MonoFix to meet all architectural requirements.

Components

Slab connector
Connects a wall panel and slab panel in a straight wall area

End beam
Aluminum extrusions with a width of 89 mm and a length as required. With one end cut at an angle of 110° for safe transfer of slab loads in connection with the prop head

Middle beam
Aluminum extrusions with a width of 89 mm & lengths of 1150 and 700 mm. The ends are cut at an angle of 110° for safe transfer of slab loads in connection with the prop head

Rocker
Connected to the bottom of a wall panel, allow easy ­stripping of the inside wall panels

BSL
Connected with wall end panel and a beam panel, it is used to form a door or a window

Prop head
Connects a middle beam and an end beam. It supports the beams during assembly, rebar fixing and concrete pouring. Provides slab support after early stripping of beams and panels

Assembly

After the form oil is applied, the outside corner is fixed to the external wall panels with round pins & wedges

The inside corner is fixed to the internal wall panels by round pin & wedge. The internal and external wall panels are connected by tie plates with PVC sleeves between the panels.

Slab connectors are installed on the top portion of the wall panels with round pin & wedge.

Middle, end beam and prop are combined by joint bars with long pin & wedge to form the beam soffits of the beams.

Dismantling 1

After 12 hours, the corner turnbuckle bracket, AL-Bracket with rail, AL-Turnbuckle bracket and wedges & pins can be removed.

AL-Bracket with rail – Ensure the formwork alignment

AL-Turnbuckle bracket – Prevent the formwork spinning

Corner-Turnbuckle bracket – Ensure the 90° angle in the corners

Dismantling 2

 

 

 

 

The internal wall formwork is removed.
The internal wall panels are moved to the upper floor through the slab opening

Dismantling 3

The external wall forms are removed, leaving in place the kicker panels. For the levels above an external working platform is fixed to the external wall. The external wall forms from the previous pour are supported by the kickers. These steps are then repeated from one floor to the next.

*All elements are recoverable

After the pouring of the following level, the screw of the kicker must be released.*
No sleeve is needed.

Dismantling 4

Reusable tie, 3 holes

Tie plates and PVC sleeves are removed with a disassembly bar

Tie sleeve (Included with the formwork)

Dismantling detail

Dismantling 5

 

 

 

The slab panels are stripped and transferred to the next level according to the designated area and installation sequence.
Long pins, joint bar and beams are removed. Prop head remains in place to support the slab.

Dismantling 6

Slab panels and slab connectors are removed and ­transferred to the next level

Prop remains undisturbed after slab dismantling
