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.

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.

A prefabricated modular reinforced concrete building system includes panel assemblies for foundations, walls, decks, and roofs designed to be built out in a manufacturing facility, shipped to a job site, and filled with concrete. Panel assemblies incorporate a space frame to ensure structural integrity during shipping and during concrete fill. Space frames can include structural columns, rebar mats, spacers, straps, and skin panels. Panel assemblies may be manufactured to contain architectural interior/external finishes, windows/doors, and pre-installed utility distribution systems.

A key-locked rebar clamping assembly includes a clamp that may be forced onto the perpendicular intersection of the upper and lower rods of crossed rebar and then held from below with a key. The assembly is readily installed by forcing the clamp over the intersection of the upper and lower rods and forcing the key through a keyway in opposing sides of the clamp. The assembly holds the rods together with the clamp at the top and the key at the bottom regardless of force, vibration, and the like applied to either rod. As the key constrains downward movement of the lower rod away from the clamp and the upper rod, the lower rod will not separate from the upper rod if walked on. The assembly reduces the need to alternate longitudinal adjacent rods between upper and lower positions, thus saving labor costs through the elimination of wire tying and complicated positioning.

An angled coupling including a main pass-through coupler to allow a first threaded rod to pass therethrough and a second coupling extending at angle therefrom to receive second threaded rod. The main coupler is configured to be secured to any location on the first threaded rod without requiring it to be screwed onto first threaded rod. The main coupler includes a first half and a second half spaced from each other that can be secured together at desired location on first threaded rod. The main coupler includes an upper section having a first approximately half of body thereof and corresponding threads and lower section having a second approximately half of body, opposite the first half, and corresponding threads. The first threaded rod is retained in both halves by insertion and rotation until the threaded rod snaps in place and kept fixed with retaining clips.

A coupling clip for coupling an upper reinforcing bar and a lower reinforcing bar includes a pair of side members spaced apart from each other and provided to be inclined with respect to the upper reinforcing bar, an upper member having a semicircle-shaped upper reinforcing bar coupling groove, and lower members being formed to vertically protrude from the lower end of each side member and having semicircle-shaped lower reinforcing bar coupling grooves. The side members and the lower members are formed to be inclined, such that a line connecting the upper part of the upper reinforcing bar coupling groove and the lower end of the lower reinforcing bar coupling groove has a vertical distance, and is perpendicular to the longitudinal direction of the upper reinforcing bar when the one-touch coupling clip is combined to the upper reinforcing bar and the lower reinforcing bar intersecting each other orthogonally.

A reinforcing stud for a stud rail includes an elongated stud body defining a first diameter. A first load transfer head is disposed at one longitudinal end of the elongated stud body. A second load transfer head is disposed at the other longitudinal end of the elongated stud body. The second load transfer head includes spaced apart mounting flanges on an end surface thereof. The mounting flanges define a channel for receiving a rail. At least one of the mounting flanges has a threaded opening through a wall thereof for receiving a set screw.

A rebar positioning device with opposite ends for positioning adjacent to a form face of at least one form panel may include a support rod having opposite ends and an outer surface, with at least a portion of the outer surface being threaded. At least one bar clip may be movably mounted on the support rod. An orientation of the at least one bar clip on the support rod is adjustable, and a position of the at least one bar clip on the support rod is adjustable.

A rebar clamp assembly for engaging a rebar rod is provided that includes a clip and a rebar clamp. The clip has a pair of prongs spaced apart from one another, connected by a bridging portion. Each prong of the pair of prongs includes an inner surface. The rebar clamp has a pair of sidewalls hingedly connected at a first end of the rebar clamp. Each sidewall includes a rebar-receiving notch on an inner surface and a plurality of clip-receiving notches disposed proximate a second end of the rebar clamp on an outer surface. The plurality of clip-receiving notches of each sidewall are configured to engage one of the inner surfaces of the pair of prongs of the clip to bring the pair of sidewalls of the rebar clamp together around the rebar rod.

A fastener assembly made up of separate clips for binding rebars together are serially connected by a carrier to form a series of clips that are separable when applied to the rebars. Each clip comprises a body having a first channel holding a first rebar and a second channel holding a second rebar underlying and transverse to the first rebar. Each channel has a bottom gap allowing a rebar to be positioned in its respective channel. The first rebar is held within the first channel by the second rebar, and the second rebar is held within the second channel by the clip body. Each clip may include at least one groove for attachment of the carrier. The rebar clips may be integrally formed from plastic or other suitable material. The carrier is flexible and severable allowing the clip string to be coiled and individual clips separated from the string.
