Wall formwork FF20

The site-ready timber-beam formwork with a system-grid

The advantages of a grid, with no frame imprint

Thanks to its ready-assembled standard elements, Doka wall formwork FF20 combines the advantages of timber-beam formwork (no frame imprints) with the grid-related advantages of a framed formwork system.

Delivered to your site ready for use

thanks to pre-assembled standard elements

The principal advantages:

  • fast forming operations even where enhanced requirements are made regarding the concrete surface

  • practical height grid

  • integral stacking flanges

  • can be rented, which makes it economical for small numbers of repeat uses as well

  • available with any form facing

Simplifies planning and optimises utilisation of the equipment

by its underlying 25 cm grid, with only a small number of different element widths

The FF20 grid logic

  • simplifies planning, forming operations and logistics on the site

  • enables the maximum-possible utilisation of the formwork

  • lowers commissioning quantities and rental costs because of its easy adaptability

Rapid forming

thanks to its practical inter-element connections

Quick, safe vertical stacking or joining by means of

  • integrated, centring stacking flange

  • special FF20 formwork element connector for crane-handling-safe, tight and slippage-free gangs

Extremely high safety

thanks to safe workplace access routes

Wall formwork FF20 can be

  • easily combined with Doka safety systems

The FF20 el­e­ments

  • Ingeniously co-ordinated panel formats for maximising utilisation of the formwork
  • The 25 cm grid, achieved with only four widths and three heights of element, simplifies planning, forming operations and logistics on the site
  • Accessories can be easily attached to the transverse walings across the entire width of the element – with no obligatory fixing points
  • Faced as standard with three-ply sheets; custom form-facing is possible whenever needed

Height grid

FF20 standard elements can be used in conjunction with stacking elements to obtain practical formwork heights of up to 6.50 m. The 2.75 m high elements are symmetrical and can also be used placed on their sides.

Vertical stacking / inter-element connections

The Fastening bolt FF20, with a star grip nut, centres and connects the vertically stacked elements in a slippage-free manner. A turn-lock makes it easier to screw on the star grip nut.

The Formwork element connector FF20/50 Z makes light work of pulling the ready-assembled FF20 elements together tightly to make an absolutely crane-handling-safe, non-slip join.

The pre-assembled elements are linked together in a 25 cm grid, permitting optimum adaptation to the structure.

 

Corners

Right-angled corners are also easy to form using the modular elements, even with different wall thicknesses of up to 60 cm.

FF20 hinged corners provide professional solutions for acute and obtuse-angled corners.

Wall formwork FF20 is also ideal for wall pillars.

FF20 can also be dimensioned for use in the horizontal – for casting floor-slabs and walls in a single pour, in fair-faced concrete quality.
