Windpost Connections & Wall Ties

Connections & Ties


The choice of fixing and its position in the structure should be considered when the windpost or parapet post has been selected. This is particularly important when the post is to be fixed to concrete. The bolt in the slotted connection at the top should be positioned so that vertical movement of the frame can take place. Typical details are shown.

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.
