Punching Shear Reinforcement

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 Leviat’s 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 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.

CE, UKCA and CE UKNI marking from Leviat

From January 1st 2021, the UK will recognise both the EU CE marking approvals, for a time limited period, and the new UK based approval system, which will be known as the UKCA mark. The EU will only recognise CE marking by EU notified bodies as proof of efficacy moving forwards. Leviat has been working closely with both EU notified and UK approved bodies to ensure compliance is achieved at the earliest possible opportunity and we can confirm that we have obtained all relevant certification.
