CONCRETE CEILING, KIT FOR PRODUCING A CONCRETE CEILING AND METHOD FOR PRODUCING A CONCRETE CEILING

The invention relates to a Concrete ceiling (1), comprising a lower reinforcing mesh (5) and an upper reinforcing mesh (2), between which a plurality of displacement bodies (10, 20, 30, 40, 50, 60, 70, 80) are disposed, wherein the lower and upper reinforcing meshes (2, 5) and the displacement bodies (10, 20, 30, 40, 50, 60, 70, 80) are embedded in concrete and each displacement body (10, 20, 30, 40, 50, 60, 70, 80) at least partially surrounds at least one channel (11, 21, 31, 41, 51, 61, 71, 81) which establishes a connection between the concrete on the lower reinforcing mesh (5) and the concrete on the upper reinforcing mesh (2), wherein the displacement bodies (10, 20, 30, 40, 50, 60, 70, 80) abut one another on at least three sides at least in sections in a central region of the concrete ceiling, whereby no additional spacers are provided between adjacent displacement bodies (10, 20, 30, 40, 50, 60, 70), so that the positioning of adjacent displacement bodies takes place by a side edge or a side wall, at which the adjacent displacement bodies contact each other and the ratio of the cross-section of the channel (11, 21, 31, 41, 51, 61) in a displacement body (10, 20, 30, 40, 50, 60) to the surface area of the displacement bodies (10, 20, 30, 40, 50, 60) in plan view is at least between 0.2 and 0.45.
