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.
10mm Plate Dowel Cradle
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.
Manufactured in 3m lengths from 6mm wire, dowel cradles are available in a wide range of configurations to suit a variety of slab thicknesses and load requirements. They form a rigid assembly capable of withstanding the harsh treatment they frequently encounter during construction activities. They are easy to transport, handle and install, saving both time and money for the contractor. Dowel Cradles can also be custom manufactured to suit any specific configuration.
Features:
Step 1
Place ground crack inducer along the joint line and secure with pins provided.
Step 2
Place the Connolly Dowel Cradles in position centrally along the joint line.
Step 3
Cut and remove shipping wires.
Note: failure to carry out this step will prevent the joint from functioning correctly.
Step 4
Pour and finish concrete.
Step 5
Saw cut to engineer’s specification along the centre line of cradle position.
