Channel & Angle Section Posts
Ancon WP1 and WP3 Windposts
Ancon WP1 and WP3 Windposts are channel section windposts which are designed to be installed within the cavity leaving the blockwork undisturbed.
The windposts are complete with end connections and ties which fit into the vertical slots in the flanges of the channel section.
Ancon WP2 Windposts
Ancon WP2 Windposts are angle section windposts designed for either small cavities or where wind loads are high. One leg of the angle windpost is built into the blockwork, and the blockwork tied through the leg of the windpost to minimise any possible movement or cracking of internal finishes. If a vertical movement joint is required in place of a tied joint, ties with a debonding sleeve on one side can be supplied.
The capacity of the post will be reduced in this configuration.
Ancon WP4 Windposts
Ancon WP4 Windposts are generally used in internal blockwork walls that have a 'fair faced' finish to both sides and where the windposts cannot protrude beyond either face. Sometimes referred to as 'spine' posts they are flat plates designed to fit within the wall. Although the depth of a WP4 post is limited by the width of the masonry (ideally 20mm less than the wall width) the thickness of the post can vary to increase its load capacity. Blockwork is tied through the post.
Ancon Parapet Posts provide lateral restraint to masonry that projects above the main structure. They are designed as 'cantilevers' and include a substantial base connection to transfer the bending moment to the structure. To ensure a practical base connection the posts are usually less than 1.6 metres in height.

Connections & Ties
Connections to the frame can be made in a variety of ways and will depend on the type of post, structure & fixing used. Typical examples of connections are shown here.
