A rebar clip is provided. The rebar clip includes a body, a rebar saddle extending from the body, an upper restraining clamp extending from the body, and a lower restraining clamp also extending from the body. The upper restraining clamp and the lower restraining clamp are configured to rotate the rebar clip to clamp the upper restraining clamp and the lower restraining clamp onto a piece of rebar.

Rebar-based support assemblies that can be fabricated without the need for on-site welding. The assemblies include a number of differing sized and shaped crimps used in place of welds to provide rebar assembly-to-rebar assembly connections. In some examples, a crimp for mechanically joining rebar for use in a support system for a physical structure includes a body with at least two recessed surfaces each configured for receiving a respective first and second piece of rebar; and a pair of spaced-apart arms at least partially enclosing an interior space of the body including the at least two recessed surfaces, a first tip and a second tip of the respective spaced-apart arms each defining a respective first and second opening to the interior space, in a first configuration.

A bracket for locating a vertical reinforcement bar within a block wall having a central area to enable a reinforcement bar placed vertically through a void of a block wall to pass through the bracket; and a locator for locating the central area in a predetermined position within the void of a block wall; wherein one or more guides extend into the central area to guide one or more reinforcement bars through a central aperture, the central aperture defined by the one or more guides.

Method for connecting rebar intersections of a foldable FRP rebar cage to allow folding and unfolding of the cage to facilitate transportation one or more rebar cages.

A rebar cage includes a rebar guide, a rebar rod, and a rebar cage connector. The rebar cage connector includes front and rear sides, a base portion having top and bottom ends, upper and lower tabs extending at angles from the top and bottom ends of the base portion, and a hook portion. The upper and lower tabs respectively include upper and lower tab openings extending through the upper and lower tabs and through the top and bottom ends of the base portion. The hook portion extends from a first end at the base portion at the rear side and curls up towards the upper tab at a second end. The upper tab opening and the lower tab opening receive the rebar rod on the front side of the rebar cage connector. The hook portion receives the rebar guide on the rear side of the rebar cage connector.

Reinforcing bar cage connectors and methods of constructing reinforcing bar cages are provided. A reinforcing bar cage includes a reinforcing bar guide, a reinforcing bar rod, and a reinforcing bar cage connector. The reinforcing bar cage connector includes a first clamp portion facing a first direction and configured to receive one of the reinforcing bar guide or the reinforcing bar rod in a first opening. The reinforcing bar cage connector includes a second clamp portion facing a second direction, opposite the first direction, and configured to receive an other one of the reinforcing bar guide or the reinforcing bar rod in a second opening. The first opening is perpendicular to the second opening. The reinforcing bar cage connector includes a metal tie wire is operable to be twisted to compress the first clamp portion and the second clamp portion.
