Ancon Shearfix Punching Shear Reinforcement

Virtually slip-free anchoring of the punching shear reinforcement

Used within a slab to provide additional reinforcement around columns, Ancon Shearfix Punching Shear Reinforcement is the ideal solution to the design and construction problems associated with punching shear. The shear load from the slab is transferred through the studs into the column. Ancon Shearfix Punching Shear Reinforcement is suitable for all column shapes and is easy to install either ‘top down’ or ‘bottom up’, depending on user preference.

  • The Ancon Shearfix Punching Shear Reinforcement offers many advantages over loose shear links. Links can be timeconsuming to both design and install.
  • The Ancon Shearfix Punching Shear Reinforcement system consists of double-headed studs welded to flat rails, positioned around the column head or base.
  • The Ancon Shearfix Punching Shear Reinforcement system is easily detailed with our free calculation program which generates a layout drawing for inclusion in the building plans and, rather than being installed individually, these studs are supplied to site welded to rails at the appropriate spacing.
  • When comparing links with studs, research has shown that any additional material costs incurred when purchasing a prefabricated stud system, such as Ancon Shearfix Punching Shear Reinforcement, are generally far outweighed by the savings from a significantly reduced fixing time; these systems being up to ten times quicker to install (source: British Cement Association:  prefabricated punching shear reinforcement for reinforced concrete flat slabs.
