<p>The plastics anchor for connecting interfacing form panels, used in concreting, into formwork elements folding together, has a spacer with anchors formed on with film hinges, each with a fitting plate as in the main patent. This spacer (1) incorporates recesses (7, 8) open towards its longitudinal edge. These may be V-shaped or round to oval, in section, and may have barbs on one or both sides. This makes it easy for fastening irons to be fitted at a constant interval from the form panel and held there so as not to move, even when concrete filling is applied.</p> |
