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.
