Ancon Shearfix comprises double-headed studs welded to flat rails. It is manufactured to suit the specific requirements of each application.
Studs are manufactured in five diameters (10, 12, 16, 20 and 25mm) from CARES-approved B500C reinforcing bar. The heads are hot forged to three times the diameter of the bar. Studs are manufactured in virtually any length to suit the depth of slab, but are normally formed in increments of 5mm within the 130-1000mm range. The bar used in this system has characteristic yield strength of 500N/mm².
Studs are welded to the rail at the centres determined by Ancon’s software or a design calculation. Shearfix rails are manufactured from strips of steel, 16mm wide x 3mm thick on studs up to 16mm in diameter and 20mm x 5mm on the larger two stud diameters. The rails feature rounded ends to reduce the risk of injury during handling. The gap between the strips allows for the passage of concrete during pouring and also enables the rail to be nailed through spacers to formwork when fixed ‘bottom up’ i.e. prior to all other reinforcement.
Each rail of studs carries an identification code generated by the Ancon design program.
To ensure the products and documentation can be cross-checked, these 16 digit reference codes are used throughout the process from design to installation. They appear on the calculation summary sheet, the DXF layout file, the parts list and on each physical rail when delivered to site.
Rails also include other references such as column number or floor level if provided at the time of ordering.
Specification and Ordering
The Ancon design program generates a 16 digit reference code, which can be used to specify/order this product. Alternatively, should you wish to manually specify each rail of studs please use the following referencing system.
Note: Rail supplied with end distance equivalent to 0.5d where spacing is 0.75d (0.6667xspacing). Other end distances available upon request.
Innovative and quick-to-install reinforcing bar couplers from Ancon replace time-consuming lapped joints and minimise reinforcement congestion in the gigantic concrete superstructure of Europe’s tallest building; the 87-floor, 462m high helicoidal Lakhta Tower in St. Petersburg.
Ancon is pleased to announce it has become one of the first businesses to transition its Occupational Health and Safety Management (OHS) to the new International standard ISO 45001:2018.
