Abstract (en)
[origin: US4667452A] A reinforcing unit for aerated concrete components. At least two spaced apart welded reinforcing mats are made up of longitudinally extending main bars and transversely extending crossbars, the crossbars being welded at their intersections with the main bars. The two mats are spaced apart from each other by connector bars which are bent into a C-shape from weldable steel bars, each connector bar having a pair of opposed legs and a spacer portion connecting those legs. The connector bars have openings to allow the passage of lifting rods. A device for forming the connector bars includes a straightening device, a device for adding small flags with holes therethrough, a bending device and a cutting device for cutting the bent connector bars and then a welding device for welding the connector bars to the mats.
