Reinforcing cage

Abstract

To product a steel-reinforced hollow-body ceiling, reinforcing cages (10) are fitted to the ceiling area. The reinforcing cages (10) have three U-shaped stays (12) each made of round steel at an angular distance, with the U-shaped stays being welded together with two horizontal rings (18, 20) to form a stable structure which can be walked upon. A container (22), open at the bottom and having aeration holes (26) in the cover (24) can be hooked into this reinforcing cage (10). In this way the container (22) becomes buoyancy-free. Reinforcing cages (10) and containers (22) are stackable, forming truncated pyramids with a hexagonal base. The reinforcing cages (10) can be positioned with little space between them. They can be walked upon and act as spacers for the upper reinforcement of the concrete ceiling. Once concrete has been poured into place, a hollow-body reinforced-concrete ceiling or slab in honeycomb structure results.
