System descriptionThe proven Doka beams, multipurpose walings and Doka formwork sheets are also used for column form-work.

▪ Cross-sections continuously adjustable up to 120 x 120 cm

▪ No form-ties through the column ▪ Clean, smooth concrete surfaces ▪ Easy assembly and handling

Design of column formwork

The Corner connecting plate 90/50 connects the wal-ings rigidly and precisely across the corner.Together with tie-rods, the Universal angle tie bracket enables the walings to be diagonally tension-braced.

☞ ▪ To achieve exact plumbing & aligning of the column formwork, the best arrangement of the panel struts is as shown above.

▪ Always attach panel struts to free-standing formwork halves to prevent them from falling over.

CAUTIONRisk of tie overload if not correctly positioned!➤ Make sure that the Universal angle tie

bracket is bolted into the right holes for the Multipurpose waling WS10 Top50 or WU12 Top50, depending on which type of waling is being used!

☞ To prevent deformation of the waling profiles, put a site-provided wooden spacer (Z) between the profiles of each waling and nail it to the Doka beam.

Pouring platforms with single brackets

As well as on wall formwork, it is also possible to use ▪ Universal brackets and ▪ Top scaffold brackets Lon column formwork.

How to mount:➤ Mount the brackets.➤ Screw on the floor decking.➤ Slot in the railing planks.➤ Put up sideguards with Edge protection system XP.

Resetting by crane

Using the easy-to-attach Lifting bracket, the col-umn formwork can be safely lifted by crane:➤ For each half of the column formwork, attach two Lift-

ing brackets to the Doka beams symmetrically (so as to ensure the centre-of-gravity position).

➤ Fit a pressure bracing between the Lifting brackets to transfer the oblique pull forces.

A Universal bracket or Top scaffold bracketB Edge protection system XP

Adjustable Universal railing shackle for easy mounting of guard-rail boards around corners and in closure zones.

CAUTION➤ It is strictly prohibited to lift the formwork

without pressure bracing.➤ Only lift one half of the formwork at a time.

☞ Important note: ▪ Spread-angle of slinging chains: max. 30°. ▪ Shore the formwork in a windproof manner

when erecting it and when it is temporarily placed in the standing position.

A Lifting bracketB Pressure bracing

CAUTION➤ Where the column is 5.0 m high or more, or

where one half of the column formwork has a dead weight of 800 kg or above, the Lift-ing-bracket for column formwork is used. Its high inherent rigidity enables the column formwork to be lifted safely by crane.

For more information, please contact your Doka technician.

It is also possible to mount the Doka column formwork platform 150/90cm on the "Lifting-bracket for column formwork".

Ladder system

Every Top 50 column must be individually planned. When doing this, remember the following points:➤ Max. column height: 10.40 m➤ The multipurpose walings to which a "Connector XS

wall formwork" is fixed will have a different length from that specified elsewhere in this User Informa-tion booklet. Plan these waling-lengths separately.

➤ Attach these longer multi-purpose walings to at least 3 Doka H20 beams (min. column width 40 cm).

➤ Position a of the top waling level: min. 24 cm below the platform decking (differs from the instructions given elsewhere in this User Infor-mation booklet)If this rule is ignored, there is a risk of collisions between the multi-purpose waling and the Universal bracket 90.

➤ To provide shear bracing, fix an Angle connector 9x5cm to the outermost beam, directly beneath the multi-purpose waling, using 4 "Universal screws countersunk head Torx 5x40mm".

➤ Position b of the extra multipurpose waling: 22 cm below the top waling level, as a pressure point.

a ... min. 24.0 cmb ... 22.0 cm

If this rule is ignored, there is a risk of collisions between the multi-purpose waling and the Universal bracket 90.

➤ Distance c from mid-point of "Connector XS wall formwork" to outside edge of beam: max. 45.0 cm

➤ Watch out for possible collisions between the Univer-sal angle tie bracket, the multipurpose waling and the System ladder XS.

Instructions for assembly and use

Preparations

➤ The half-shells are pre-assembled face-down on an assembly bench.

➤ Mount the platforms to the face-down element.➤ Mount the 'Ladder system' components to the face-

down element.➤ Mount the panel struts to the face-down element.

Erecting the formwork

➤ Attach the lifting chain to the lifting-brackets pro-vided.

➤ Raise the half-shell by crane and lift it to the erection location.

➤ Fix the panel struts to the ground stably.➤ Mount the top guard-rail boards.

➤ Detach the half-shell from the crane.

Preconditions for use:

Platforms and all accessories must only be mounted to the element when this is face-down on the ground.

It must be possible for all formwork set-up, pouring and stripping operations to be carried out from safe workplaces.

A good way of creating safe workplaces is to use a mobile scaffold tower.

The professionals from the Doka "Ready-to-Use Service" plan and assemble site-ready and custom formworks exactly to your speci-fications.

Setting up the second half-shell

Once the reinforcement has been placed, the form-work can be closed.➤ Raise the second half-shell by crane and lift it to the

erection location.➤ Join the second half-shell to the first half-shell.

➤ Detach the half-shell from the crane.

Striking

➤ Remove any loose items from the formwork and plat-forms, or secure them firmly.

➤ Attach the first half-shell (the one without panel struts) to the crane.

➤ Undo the connections between the first and second half-shell.

➤ Lift away the first half-shell by crane and place it down flat for intermediate storage.

➤ Attach the second half-shell (the one with panel struts) to the crane.

➤ Undo the ground anchors of the panel struts.➤ Lift away the second half-shell by crane and transfer

it to its next location, or place it down flat for interme-diate storage.

WARNINGThe formwork tends to adhere to the concrete. When stripping the formwork, do not try to break concrete cohesion using the crane!Risk of crane overload.➤ Use suitable tools such as timber wedges or

a special pry-bar to detach the formwork from the concrete.
