Latest Patents
Parkes' latest patents include a "System of protecting the edges and construction joints of cast in place concrete slabs." This invention presents an improved joint edge assembly designed for the construction of concrete slabs. The assembly features a longitudinal joint rail, preferably made of steel, which is supported off the ground by formwork. The joint rail consists of first and second joint edge members connected by interference-type connectors with self-release elements. A series of studs extend downward and outward from each joint edge member into the concrete slabs, ensuring a robust mechanical connection. As the concrete shrinks during hardening, the self-release elements allow the joint to open freely, thus protecting the edges of adjacent slab sections from damage. Additionally, a dowel aligner can be integrated into the assembly for proper positioning of dowels within the slab.
Another patent by Parkes is also focused on protecting the edges of cast-in-place concrete slabs on the ground. This improved joint edge assembly similarly comprises a longitudinal joint rail supported by temporary formwork and secured with mounting brackets. The design includes connectors with self-release elements, allowing for an expandable joint that protects adjacent slab edges from damage.
