Wall formwork FF20

The site-ready timber-beam formwork with a sys­tem-grid and no frame im­prints

With its prac­ti­cal el­e­ment size-grid, rapid stack­a­bil­i­ty and slip­page-free in­ter-el­e­ment con­nec­tions, FF20 is the right choice for many pro­jects where stric­ter re­quire­ments are made re­gard­ing the con­crete fin­ish.

De­liv­ered to your site ready for use
in pre-as­sem­bled stan­dard el­e­ments 

  • fast forming, even when tough spe­c­i­fi­ca­tions are made re­gard­ing the con­crete fin­ish, by com­bin­ing the ad­van­tages of timber-beam formwork with the grid-re­lat­ed ad­van­tages of a framed formwork sys­tem
  • adapts eas­i­ly to any struc­ture, thanks to its prac­ti­cal el­e­ment size-grid
  • can be rent­ed, so is al­so eco­nom­i­cal for small num­bers of re­peat us­es
  • pro­ject-spe­cif­ic adap­ta­tion pos­si­ble, as it can be faced with any type of form-ply

Max­imised util­i­sa­tion of equip­ment
as there are on­ly a few dif­fer­ent el­e­ment widths 

  • 25 cm in­cre­ment grid sim­pli­fies plan­n­ing, forming op­er­a­tions and lo­gis­tics on the site
  • low­ers com­mis­sion­ing quan­ti­ties and ren­tal costs be­cause of its easy adapt­a­bil­i­ty

Rapid forming
thanks to its prac­ti­cal in­ter-el­e­ment con­nec­tions 

  • quick and safe ver­ti­cal stack­ing fa­cil­i­tat­ed by in­te­gral cen­tring stack­ing flange
  • crane-han­dling-safe, tight, slip­page-free gangs achieved by spe­cial FF20 formwork el­e­ment con­nec­tor

Com­pre­hen­sive work­place safe­ty
with com­pat­i­ble lad­der­ways and work­ing plat­forms 

  • safe ver­ti­cal ac­cess with the Lad­der sys­tem XS
  • work­place safe­ty on all sides with the Platform sys­tem Xsafe plus
  • prac­ti­cal accessories – such as pan­el struts, lift­ing/re­po­si­tion­ing de­vices etc. – make for safe, easy han­dling of the formwork

For the contractors building the new G3 shopping centre in Gerasdorf, near Vienna, the crucial factors were cost effectiveness, swift construction progress and safety. The quality products supplied by Doka, such as FF20 wall formwork, also delivered optimum concrete results.

A 160 m long ramp, with walls of constantly varying height, had to be cast in sixteen 10 m long sections here. The standard elements of the FL20 U100 system, with their easy height-adjustability, were the ideal equipment for this project, and also met all the fair-faced concrete specifications.

System

The FF20 el­e­ments

  • ingeniously co-ordinated panel formats, for getting maximum utilisation from the formwork
  • 25 cm grid, 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 upside-down.

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.

Corn­ers

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

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.
