| 20090235601 | WALL UNIT - A method of manufacturing a wall unit comprises assembling a set of substantially parallel vertical elongated wall ties having opposite edges which are substantially coplanar on each side of the set. Each wall tie has a plurality of triangular openings distributed along its length with the openings of adjacent wall ties substantially aligned in a horizontal direction. A plurality of reinforcing rods are inserted horizontally through respective sets of aligned openings. Due to the triangular configuration of the openings each rod is deflected under gravity towards, and comes to rest adjacent, an edge of the wall tie. One or more formwork panels are secured to the substantially coplanar edges on each side of the wall ties. | 09-24-2009 |
