A prong is configured for use with a concrete reinforcement element and includes first and second legs positioned opposite first and second sides of the prong and a bridge portion connecting distal ends the legs, where the bridge portion forms a first end of the prong. The legs extend from the bridge portion to a second end of the prong opposite the first end, and each of the legs has a proximal end at the second end of the prong. The proximal end of the first leg is bent toward the second leg, and the proximal end of the second leg is bent toward the first leg, such that the proximal ends of the legs overlap each other. Inner surfaces of the proximal ends of the legs define engagement surfaces configured to engage a tie wire, enabling the proximal ends to be connected to the tie wire.
E04F 15/06 - Flooring or floor layers composed of a number of similar elements of metal, whether or not in combination with other material
E04F 19/10 - Built-in gratings, e.g. foot-scrapers
F16L 9/08 - Rigid pipes of concrete, cement, or asbestos cement, with or without reinforcement
E04C 5/16 - Auxiliary parts for reinforcements, e.g. connectors, spacers, stirrups
E04C 5/06 - Reinforcing elements of metal, e.g. with non-structural coatings of high bending resistance, i.e. of essentially three-dimensional extent, e.g. lattice girders
