Reinforcement cage and its arrangement for the production of reinforced concrete hollow slabs

摘要

To produce a hollow reinforced concrete ceiling, the ceiling area is covered with reinforcement cages (10), each with three U-brackets (12) made of round steel at an angular distance, which are welded with two horizontal rings (18, 20) to form a stable, walkable body. A container (22) open at the bottom is suspended in this reinforcement cage (10), the top wall (24) of which has ventilation holes (26). The container (22) is buoyancy-free. Reinforcement cages (10) and containers (22) can be stacked one inside the other and form truncated pyramids with a hexagonal base. The reinforcement cages (10) can be positioned close together. They can be walked on and act as spacers for the upper reinforcement of the concrete ceiling. After filling with concrete, a hollow body reinforced concrete ceiling or slab with a honeycomb structure results.
