Jordahl Punching Shear Reinforcement JDA

JORDAHL® Punching Shear Reinforcement - JDA comprises of double-headed reinforcement anchors that are factory-welded to carrier rails. Installed into the concrete from above, the units are positioned in floor slabs and foundation slabs to distribute punching shear loads above column or pile locations. Typically supplied in two to five stud configurations, JDA units replace the need for drop beams or closely spaced traditional link reinforcement. This reduces cost and reinforcement congestion.
