8 FERRULE INSTALLATION Upward Placed Ferrules Insert a N12 x 300mm cross rod if required. Place in an appropriate height ferrule support chair for the concrete element thickness. Insert appropriate size antenna cap for the ferrule size. Tie cross rod to the ferrule support chair, mesh and reinforcing. If there is no cross rod, tie the ferrule and the ferrule support chair, mesh and reinforcing. Downward or Horizontal Placed Ferrules Insert a N12 x 300mm cross rod if required. Place an appropriate size nailing plate in the position for the ferrule on the table, panel below or formwork with nail or doubled sided glue spots or squares. Screw or push on the ferrule dependent on the type of nailing plate. Tie cross rod to the ferrule support chair, mesh and reinforcing. If there is no cross rod, tie the ferrule and the ferrule support chair, mesh and reinforcing. Double Ended Ferrules Insert a N12 x 300mm cross rod. Place an appropriate size nailing plate in the position for the ferrule on the table, panel below or formwork with a nail or doubled sided glue spots or squares. Insert appropriate size antenna cap for the ferrule size. Screw or push on the ferrule dependent on the type of nailing plate. Tie cross rod to the ferrule support chair, mesh and reinforcing. Bolts It must be tap and finish compatible with the ferrule. High tensile bolts must be used in structural connections. The bolt must be installed as per manufacturer s specifications. Washers The washer must be tap and finish compatible with the bolt. FERRULE SPECIFICATION A suitably qualified design engineer must specify each of the following: Number of ferrules required, their size and their finish. Position of the ferrules. Concrete strength that the ferrules will be cast into. Type of connection that the ferrule is to be used in. Type of joining plate or fixing that the bolt and ferrule are securing to the concrete element. Size and thickness of the washer used in the connection. Grade, size, length and finish of the bolt used in the connection. Size of mechanical fixing used as a result of lost ferrules and must be installed as per manufacturer s specifications. 8

9 FERRULE SUPPORT CHAIRS An easy-to-use ferrule chair was developed to locate face-up ferrules in precast and tilt-up panels. This chair is designed to locate the ferrule (with antennae cap) to about 1 to 2mm below the panel surface when a 96mm ferrule is used. One style for the Standard ferrules and one for the Confoot Ferrules. A major time saver the ferrule chair is manufactured to provide a strong, impact resistant support which is noncorrosive and having minimal exposure. Available to suit all 96mm ferrule for panel thicknesses of 125,150,175,180 and 200mm. Concrete Grey. Strong feet with minimal exposure. Hollow centre to ensure bar is in place. Tagged for easy identification. Ridged - locating support for ferrule. ANTENNA CAPS An easy-to-use ferrule plug was developed to locate face-up ferrules in precast and tilt-up panels. This plug is designed to locate the ferrule (with support chair) to about 1 to 2mm below the panel surface when a 96mm ferrule is used. A major time saver the ferrule antenna cap is manufactured to provide a tight fitting plug, to keep slurry out of the ferrule during casting, which is noncorrosive and having minimal exposure. Available to suit any length ferrule in sizes M12, M16, M20 and M24. Colour coded to aid identification and selection. Ridged to hold the cap firmly in the ferrule. Antennas to allow location when stripping the panel. 9

10 NAILING PLATES An easy-to-use ferrule nailing plate was developed to locate face-down and double-ended ferrules in precast and tilt-up panels. This nailing plate is designed to locate the ferrule on the bottom face of the panel. The cross bar is wired to the reinforcing to hold it vertical. A major time saver the ferrule nailing plate is manufactured to provide a tight fitting plug (to keep slurry out of the ferrule during casting) and to locate it in the correct position. It is noncorrosive and has minimal exposure. Available to suit any length ferrule in sizes M12, M16, M20 and M24 Three styles: 1) Quick Fit NP that clips into the ferrule and is fixed in place with a double sided adhesive circle or square. 2) Thin NP that screw into the ferrule and is fixed in place with a double sided adhesive circle or square. 3) Thick NP that screw into the ferrule and is mechanically fixed to the formwork. Colour coded to aid identification and selection. Ridged or with a thread to hold the ferrule firmly on the nailing plate. 10
