JORDAHL® Punching Shear Reinforcement JDA

Application

  • Flat slab concrete construction.
  • Precast filigree slabs.

Description

Double-headed reinforcement anchors which 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.

Features and benefits:

  • High load transfer.
  • Reduces reinforcement congestion.
  • Enables flat slabs without thickening at columns or the need for drop beams.
  • European Technical Assessment - ETA-13/0136

Application:

  • Flat slab concrete construction.
  • Precast filigree slabs.
