Connections & Ties
The choice of fixing and its position is dependant on the type and length of the windpost and the structure to which it is being fixed. Leviat designs fixing details for the top and base of each Ancon windpost and a drawing is issued for approval prior to manufacture. The bolt in the slotted connection at the top of the windpost is positioned so that vertical movement of the frame can take place. The details shown are typical.
The type of fixing will depend on the frame. Expansion bolts are normally supplied for concrete frames and set screws will be supplied for steel frames.
A range of ties is available to suit Ancon Windposts. SDN Ties are used to the outer leaf and SPN Ties to the inner leaf. SNS Ties are used across the posts in the inner blockwork and can be supplied with a debonding sleeve for use where there is a vertical movement joint.
With their new European Technical Assessment (ETA), Halfen HZA serrated anchor channels fulfil all requirements of AS 5216:2021 and can be used in projects across Australia.
Leviat has released an enhanced version of its popular Ancon Shearfix design software that enables engineers to maintain a flat concrete slab at column heads by reinforcing the area against punching shear with a prefabricated, stud-rail system.
