The new heavy-duty Stacon shear force dowel type SLD from Schöck is really compact; and as the anchoring bodies have been reduced in size, it has the advantage of enabling higher loads to be installed in thinner slabs and walls, optimising on-site reinforcement. Which can mean fewer dowels being required for the same load. A higher load capacity can even be achieved with a slab thickness of 500mm. Years of research have been invested in the development of the new Schöck Stacon and it is the only UK dowel product to have undergone such extensive testing. This involved up to 2000 longitudinal and transverse displacement cycles per test, along with an exhaustive examination of its load-bearing capacity and its fire behaviour. Resulting in the new Schöck Stacon being awarded United Kingdom Technical Assessment (UKTA) along with fire protection classification R 120. By using high-quality stainless steel, the Schöck Stacon dowels guarantee a safe and maintenance-free connection.

There are two main variants, the Schöck Stacon SLD for the transmission of high transverse forces in expansion joints between thin concrete structural components, offering freedom of movement in the direction of the dowel axis. Also, the SLD-Q, which has a unique square bar and is for the transmission of high shear forces between thin concrete structural components with freedom of movement both along and transverse to the dowel axis

The type LD

There is a single shear dowel as well, the Schöck Stacon dowel type LD, which offers a simple solution for force transmission in expansion joints. It connects the components adjacent to the joint without any additional construction and in doing so, the shear forces are transferred and any required movement made possible. Complex double walls or corbels for load transfer can be omitted by using the LD. It is the first single shear dowel to be awarded United Kingdom Technical Assessment (UKTA).

Web-based design too

The Schöck Stacon dowel type SLD is innovative, but so is Scalix, the supporting design software. Scalix is the first web-based application for the design of shear dowels and it is always up-to-date with no installation required. The Schöck products, both SLD and LD, can easily be calculated using a single, modular solution. Scalix enables simple planning, design and verification of all shear force dowels in one tool; selection of the most economical dowel variant; and optimisation of on-site reinforcement. The modular software runs on all common browsers, calculations can be saved and loaded locally as a file. In addition, the latest software allows projects to be loaded that are in earlier release versions.
