Abstract
A reinforced concrete ceiling is characterized by a combination of the following features: a concrete slab (1) the thickness (D) of which falls short of the total thickness of the reinforced concrete ceiling, and intersecting ribs (2) which are each connected with an end region (3) to the concrete slab (1) in a force-transmitting manner and project freely upwards from the concrete slab (1), i.e., without being integrated in a further supporting surface structure, wherein their top end regions (4) are designed to absorb compressive and/or tensile forces and wherein the ribs (2) are connected to each other in a frictional manner at the respective intersection points (9), and their regions lying in each case between the top and bottom end regions (3,4) have at least one aperture (6).
