Double-headed shear rail reinforcement system to distribute punching shear forces in concrete floor slabs

Jump to:
+44 (0)1844 215 200 Website

Application

JDA shear rail units replace the need for drop beams or closely spaced traditional link reinforcement in floor slabs that are subject to punching shear loads. This reduces cost and reinforcement congestion.


Installed into the concrete from above, the stud rail units are positioned in floor slabs and foundation slabs to distribute punching shear loads above column or pile locations.


Typical Applications:

  • Flat slab concrete construction.
  • Precast filigree slabs.

Description

Double-headed stud reinforcement anchors are factory-welded to carrier rails. They are typically supplied in two to five anchor configurations.


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.
