Description
Connolly Expansion Joint
The Connolly Expansion Joint is a continuous pour solution for expansion joints in slab on ground applications.
The straight profile guarantees that the load is transferred through the dowels only.
Connolly Expansion Joints are a roll-formed galvanised steel section with 10mm cross-linked foam to provide a leave in place formwork that allows for joint expansion. The profile is fixed in place using the patented peg and wedge system.
The Expansion Joint profile 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 twist-fix feature. The preformed holes will accommodate round dowels up to 30mm diameter and square dowels up to 24mm.
The Expansion Joint profile is available in 3m lengths for slab thicknesses from 100mm to 200mm. Custom heights, lengths (up to 3m), and dowel configurations are available on request.
A wide range of permanent capping and rebate moulds are available to be used with Connolly Expansion Joints.
