How this node works
At the edge the cable is locked to a steel bearing plate by wedges that grip the strands. The plate concentrates a huge force into the concrete, so a spiral or links of bursting reinforcement wrap the zone to stop it splitting. The pocket left for the jack is then cut and grouted, protecting the head from corrosion.
