Connolly® Key Joint System

Connolly^® Key Joint System

Connolly^® Key Joints supplied by InfraBuild Reinforcing, are a continuous pour solution for contraction joints in slab on ground applications. Connolly Key Joints are a roll formed galvanized steel section used as a leave-in-place formwork to control shrinkage induced cracking. The profile is fixed in place using the patented peg and wedge system.

The unique tongue profile provides positive load transfer with minimal stepping. For higher load applications the preformed knock-outs allow Key Joints to be used in conjunction with Connolly Universal Dowel Sleeves (UDS).

Key Joints are available in 3 and 6m lengths for slab thicknesses from 100mm to 300mm.

Typical Uses

• Contraction joints in slab-on-ground applications

Features
