An adjustable concrete form brace includes a horizontal adaptable extension member. A first lower brace element and a second lower brace element opposing the first lower brace element each have a horizontal insertion channel adapted to receive the horizontal extension member. A first upper brace element and second upper brace element are attached to the first lower brace element and the second lower brace element respectively. Each of the lower brace members include a saddle, and each saddle is adapted to retain one or more reinforcement bars. The first upper brace element and second upper brace element each include a form retaining element.

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 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 lateral reinforcement system for a concrete structure having axially disposed structural bars. The lateral reinforcement system comprises a plurality of reinforcement ties disposed at an inclination to the axially disposed structural bars. A pair of reinforcement ties of the plurality of reinforcement ties is disposed at mirror inclinations to each other. In the pair of reinforcement ties, the reinforcement ties cross each other at diametrically opposite corners of the reinforcement ties at diametrically opposite axially disposed structural bars, such that, a first reinforcement tie of the pair of reinforcement ties crosses from inside of a second reinforcement tie of the pair of reinforcement ties at one structural bar, and the second reinforcement tie crosses from inside of the first reinforcement tie at the diametrically opposite structural bar. The plurality of reinforcement ties forms a three-dimensional interwoven network around the axially disposed structural bars.

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 three-point supporting anchor integrated liner and a long anchor integrated liner allows for positioning machine accessory anchor bolts before machine foundation reinforced concrete for installing a machine is assembled and poured. The three-point supporting anchor integrated liner includes: a first shaft that is longer than a height difference dimension between a top rebar of a foundation reinforcement cage buried in the machine foundation reinforced concrete and a slab top; a second shaft that extends in a direction intersecting with the first shaft and allows both ends to intersect with and be tied to a rebar; and a coupling portion that ties the second shaft or couples the second shaft by screwing to the first shaft in a state where the second shaft intersects with the first shaft.

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.
