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 ofthe panel struts is as shown above.
▪ Always attach panel struts to free-standingformwork halves to prevent them from fallingover.
CAUTION
Risk of tie overload if not correctly positioned!
➤Make sure that the Universal angle tiebracket is bolted into the right holes for theMultipurpose waling WS10 Top50 or WU12Top50, depending on which type of waling isbeing used!

☞To prevent deformation of the waling profiles,put a site-provided wooden spacer (Z) betweenthe profiles of each waling and nail it to theDoka beam.
As well as on wall formwork, it is also possible to use
▪ Universal brackets and
▪ Top scaffold brackets L
on 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 asto ensure the centre-of-gravity position).
➤ Fit a pressure bracing between the Lifting brackets totransfer the oblique pull forces.

CAUTION
➤ It is strictly prohibited to lift the formworkwithout 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 mannerwhen erecting it and when it is temporarilyplaced in the standing position.

CAUTION
➤Where the column is 5.0 m high or more, orwhere one half of the column formwork hasa dead weight of 800 kg or above, the Lift-ing-bracket for column formwork is used.Its high inherent rigidity enables the columnformwork to be lifted safely by crane.
For more information, please contact yourDoka technician.
It is also possible to mount the Doka columnformwork platform 150/90cm on the "Lifting-bracket for column formwork".
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 XSwall formwork" is fixed will have a different lengthfrom that specified elsewhere in this User Informa-tion booklet. Plan these waling-lengths separately.
➤ Attach these longer multi-purpose walings to at least3 Doka H20 beams (min. column width 40 cm).
➤ Position a of the top waling level:min. 24 cm below the platform decking (differs fromthe instructions given elsewhere in this User Infor-mation booklet)
If this rule is ignored, there is a risk of collisionsbetween the multi-purpose waling and the Universalbracket 90.
➤ To provide shear bracing, fix an Angle connector9x5cm to the outermost beam, directly beneath themulti-purpose waling, using 4 "Universal screwscountersunk head Torx 5x40mm".
➤ Position b of the extra multipurpose waling:22 cm below the top waling level, as a pressurepoint.
a ... min. 24.0 cmb ... 22.0 cm
If this rule is ignored, there is a risk of collisionsbetween the multi-purpose waling and the Universalbracket 90.
➤Distance c from mid-point of "Connector XS wallformwork" to outside edge of beam:max. 45.0 cm
➤Watch out for possible collisions between the Univer-sal angle tie bracket, the multipurpose waling andthe System ladder XS.
