HALFEN Punching Shear Reinforcement
The HDB elements with double headed ribbed studs, welded to a mounting rail, are used as shear and punching reinforcement. HALFEN HDB shear rails are supplied as system elements, for short delivery times, and as complete elements, which are manufactured to measure on demand. They are preferably put in from the top after laying the flat slab reinforcement.
They are available as 2-stud and 3-stud elements which can be combined into larger assemblies with the appropriate arrangement. The symmetrical arrangement of the HDB anchor guarantees the correct installation. The clip bar ensures that the heads of the studs are covered by concrete.
