Design of column formwork
|
|
NOTICE ▪ To achieve exact plumbing & aligning of the column formwork, the best arrangement of the panel struts is as illustrated here. ▪ Always attach panel struts to free-standing formwork halves to prevent them from falling over. |
The Corner connecting plate 90/50 connects the walings rigidly and precisely across the corner.
Together with tie rods, the Universal angle tie bracket enables the walings to be diagonally tension-braced.
|
|
CAUTION Risk of tie overload if not correctly positioned! ➤ Make sure that the Universal angle tie bracket is bolted into the right holes for the Multi-purpose waling WS10 Top50 or WU12 Top50, depending on which type of waling is being used! |

Note:
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.

As far as possible, set the angles of the form ties in the same ratio as the length-to-width ratio of the column cross section.
