Anchor bolt assemblies, cages & templates

Why cages

Most site problems with steel erection start at the foundation: anchor bolts out of position, rotated or set at the wrong projection. A cage holds the whole bolt group – with a template at the top and a ring plate at the bottom – so it is placed, levelled and tied to the reinforcement as one piece.

What we supply

• Anchor bolts to F1554, AS 1111 or ISO 898-1
• Top template plate drilled from the column base plate drawing
• Bottom ring or spacer plate, tack-welded where permitted
• Plastic or steel sleeves for ± adjustment
• Levelling nuts, plate washers, thread protection
• Tag with foundation mark and grid

Setting

• Check the template against grid lines and level before the pour
• Tie the cage to the reinforcement – not to the formwork
• Protect threads; remove templates after the concrete has set
• Survey bolt positions before steel erection
