Egcodorn Shear Connectors



Egcodorn™ Shear Dowels provide high performance transfer of shear forces across movement joints up to 60mm wide, in a simple corrosion resistant design to suit thin concrete slabs.The key to Egcodorn™ Shear dowel’s high load capacities is its' patented high tensile steel core dowel. This provides superior strengths to what a stainless steel dowel can achieve, whilst exhibiting the same corrosion resistance through its exterior stainless steel sleeve.

Egcodorn™ Shear Dowels  - Features
• High tensile steel core dowel
• Corrosion resistant stainless steel body and dowel sleeve
• Simple configuration for simple installation
• Accommodates lateral & longitudinal movements (DQB type only)
• Optimised body design for use in thin slabs
• Fire rated, acoustic, and dynamic load options available
• Additional in-situ reinforcent detailing provided

*For 10mm joint widths in 32MPa concrete.  This value will reduce for wider joints, reduced concrete strengths, and thin slabs.
  Nail the Egcodorn sleeve (female) to the inside of the formwork for the first concrete pour
  Install Egcodorn in-situ reinforcement as shown in the Reid design detail, and pour the first concrete slab
  Strip formwork and remove the label from the Egcodorn sleeve to reveal the dowel cavity
  Install fire collars and mineral wool expansion joints, if required
  Install the Egcodorn shear dowel into the cast-in Egcodorn dowel sleeve
  Install Egcodorn in-situ reinforcement as shown in the Reid design detail, and pour the second concrete slab

The combination of high localised shear force, low slab thickness and close proximity to an edge requires the use of additional punching shear reinforcement around shear dowels. Punching shear reinforcement bridges the crack zones across the thickness of the slab and along the slab’s edge surrounding the shear dowel.  This ensures the concrete is sufficiently reinforced to enable the shear dowel to transfer shear forces across the movement joint, which becomes even more critical as the joint width becomes larger.

The diagram below provides an example of the reinforcement requirements needed for Egcodorn™ shear dowels*.  The dimensions for these details are provided with every quotation or purchase order, delivering all of your requirements in one package when using Egcodorn™ shear dowels.



*Note: The reinforcement detailing provided for Egcodorn™ shear dowels do not apply for alternative shear connection systems or designs.



Fire-ratings, acoustic dampening, and dynamic load force applications are available using Egcodorn™ shear dowels.  

Fire protection boards are available for installation over the dowel to provide fire rated joints, and are adapted to suit the slab thickness. 

By switching the dowels’ female end to an Egcotritt™* acoustic decoupler, impact sound transmission can be reduced by up to 30dB – ideal for stair landings, exterior corridors, floors and building foundations.

Through our association with Max Frank GmbH & Co, Reid can offer customised shear dowel solutions for dynamic loads in applications such as car park ramps, train lines, bridges, and other trafficable infrastructure.
