Comparison with Shear Links
Ancon Shearfix offers many advantages over loose shear links. Links can be time-consuming to both design and install. A Shearfix system is easily detailed with our punching shear reinforcement design 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 Shearfix, 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.
