Dokaflex 1-2-4
The fast, versatile hand-set system
No compromises when it comes to layout and concrete finish
Dokaflex 1-2-4 is the fast, versatile floor-slab formwork for any desired layout. The quantities can easily be computed using a slide-rule, so no detailed formwork planning work is needed. Any type of form-facing can be used, enabling all architectural wishes regarding the concrete surface to be met.

Safe and fast to set up
thanks to pre-defined system gridWith Dokaflex 1-2-4, you'll be working faster and more safely
only 2 different lengths of beam
the markings on the beams make it easy to set up, with an easy-to-see safety check
Adaptability to all layouts
thanks to flexible gridThe flexible floor-slab formwork grid for
any shape of layout – downstand beams and floor extensions can easily be solved "within the system"
perfect adaptability to columns and walls
optimising for different slab thickness
shoring filigree slabs
Highly cost-efficient
thanks to the use of long-lived system componentsDesigned for perfect interoperability, the system components give you
very high numbers of re-use cycles
reduced close-out costs
simplified site logistics
first-rate concrete surfaces
Floor prop Eurex top
The first-ever floor prop with an impact protector from Doka
- unbeatably durable, due to impact protector
- light and safe, thanks to new lightweight design
- easy to back off, using integral quick-lowering feature
- quick height adjustment, helped by numbered holes
Beam H20 top
Up to 3 times the lifespan, thanks to built-in shock absorber
- long life unmatched by any other beam, thanks to its integral shock absorber
- fast, safe formwork set-up by referring to markings on the flanges
- beams can be labelled – deters theft and uses the beams as an advertising vehicle
- its innovative ends give it an innovative edge!
ProFrame panel
Newly developed frame maximises repeat-use numbers
- cuts costs with option to either purchase or rent
- re-use cycles maximised by the newly developed frame of the ProFrame panel, which gives special protection to the corners in the same way as a shock absorber
- used with Doka floor-slab systems
Here's how easily the system works
1-2-4 – these are the maximum spacings for setting-up Dokaflex 1-2-4. Triangular marks on the beams serve as a built-in "measuring tape".
- 1 mark = maximum spacing of secondary beams
- 2 marks = maximum spacing of props
- 4 marks = maximum spacing of primary beams
Doka floor end-shutter clamp
This quick and easy system solution for stop-ends now provides even greater safety at the edges of floor-slabs, and greater flexibility, with a choice of different attachment methods, types of stop-end and ways of safeguarding slab edges.
A clean solution for downstand beams
The Beam forming support 20 lets you quickly and accurately adjust the formwork for downstand beams, right down to the last millimetre. To do this, the Beam forming support is simply placed onto the secondary beams and tightened with a few blows of the hammer. This automatically pulls the side-formwork tight, for clean concrete faces.
