Abstract: A concrete reinforcing bar connector is described as a resilient clip to hold together two intersecting reinforcing bars, said clip comprising two open longitudinal ‘C’ shaped (grooves), with at least one triangular gusset connecting said ‘C’ shaped faces of said clip, said clip is aligned with said intersecting reinforcing bars and forcibly engaged over said reinforcing bars, said bars configured to intersect at right angles to each other. In one preferred reinforcing bar configuration, the first bar terminates at the second bar, in a second configuration the first bar continues beyond the second bar.

Abstract: A specific type of preassembled lightweight floor panel comprising, a subassembly of steel trusses separated by panels of insulation panels, with the edges of the insulation panels beveled in such a manner as to expose the top and bottom chords of the trusses, the first cementitious layer cast on the lower face by forcably immersing this subassembly in a thin layer of cementitious fluid until the bottom chord of the steel trusses is encased, then after the floor panels and all of the surrounding structural elements are instaled, a second layer cementitious cast over these floor panels providing these panels with a finished floor surface and permanently attaching this floor panel to the walls above and below the floor these specific floor panels are used above grade on dwarf walls, piers, on floors over basements, on floors between upper levels and on flat roofs.
