Connolly Straight Up Contraction Joint

Connolly Straight Up Contraction Joints are a roll-formed galvanised steel section to provide a leave-in-place formwork. The profile is fixed in place using the patented peg and wedge system. The straight profile guarantees that the load is transferred through the dowels only.

The Straight Up Contraction Joint has pre-formed holes which allow it to be used in conjunction with Connolly Universal Dowel Sleeves (UDS). The Universal Dowel Sleeves are installed in the steel section using the patented Connolly twist-fix feature. The preformed holes will accommodate round dowels up to 30mm diameter and square dowels up to 24mm.

The Straight Up Contraction Joint profile is available in 3m lengths for slab thicknesses from 125mm to 200mm. Custom heights, lengths (up to 3m), and dowel configurations are available on request.

The Straight Up Contraction Joint utilises the Key Joint range of permanent and removable capping and rebate moulds.
