Ancon Shearfix is used within a concrete slab to provide additional reinforcement around column heads, protecting the slab from the effects of punching shear.

Shearfix offers many advantages over the use of loose shear links, which can be time-consuming to both design and install. A Shearfix system comprises double-headed steel studs. To simplify installation, and ensure alignment and accurate positioning within the slab, the studs are supplied welded to flat rails. Ancon distributes free design software and provides free design assistance. Ancon's Technical Services Team has created a faxback form for engineers to effectively summarise the critical details of their project and to request assistance with a Shearfix design. The Shearfix software and design sheet can either be downloaded from www.ancon.co.uk or are available on request from Ancon on +44 (0)114 275 5224 and info@ancon.co.uk.
