Connolly Key Joints
Connolly Key Joints are an expansion joint that provides a durable and rigid straight line that can be utilised for expansion joint forming in either end of pour or continuous pour situations. They are basically a galvanized steel tongue and groove formwork which when installed joins the slab to form the control joint.
A Connolly peg and wedge system is used to hold the joint in place. Installation is quick and easy and delivers precise height adjustments. The rigid steel profiles produce straighter joints. Useful for controlling cracks on large slabs, including residential home slabs and industrial applications.
The system includes dowels, sleeves, expansion foam, wedges and pegs and is available in 6m lengths and 3 heights, 100, 150 and 200mm.
Connolly EXJ Expansion Joint System
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.
Connolly Key Joint
Connolly Key Joints are a continuous pour solution for contraction joints in slab on ground applications.
They are a roll-formed galvanised 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.
Our unique tongue profile provides positive load transfer with minimal stepping.
Connolly Dowel Cradles
Dowel cradles are used for load transfer in saw cut contraction joints. They are a welded wire assembly that ensures the horizontal and vertical alignment of dowels at the correct spacing and height.
Maintaining correct alignment of dowels across the joint is recognised as being the most important aspect of forming a dowelled joint.
Connolly dowel cradles are produced with either round, square or plate dowels. All Dowel Cradles are supplied with a de-bonding sleeve to one half of the dowel to allow for contraction. Square and plate dowel Cradles also allow for lateral movement.
Biscuit Plate Dowels
Connolly Biscuit Plate Dowels and Sleeves are designed to transfer loads across construction joints in slab-on-ground applications.
The plastic sleeve encases one half of the plate dowel to de-bond the dowel from the concrete. Connolly Biscuit Plate Dowels allow for expansion, contraction and lateral movement at the joint.
Available in 6mm and 10mm thickness in black, hot-dip galvanised or stainless steel finish. With pre-installed nails, and V-notches on all sides, they can be easily and accurately installed on conventional formwork, ensuring perfect dowel alignment.
Universal Dowel Sleeves
Connolly Universal Dowel Sleeves are available for round and square dowels, to allow for load transfer across joints in slab-on-ground applications.
The sleeve encases one half of the dowel to de-bond the dowel from the concrete. All Connolly Universal Dowel Sleeves allow for expansion and contraction at the joint. Square dowel sleeves also allow for lateral movement at the joint.
The Universal Dowel Sleeve is equipped with a patented, integrated support leg, which can be adjusted to suit multiple slab heights. This unique feature assists with accurate dowel alignment.
Straight Up Contraction Joint
The Connolly Straight Up Contraction Joint is a continuous pour solution for contraction joints in slab on ground applications.
The straight profile guarantees that the load is transferred through the dowels only.
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.
