Abstract (en)
[origin: WO9707949A1] The present invention relates to a method and apparatus for producing a composite structure comprising a sheet metal bottom plate (6) and a concrete layer (18). The upper surface of the bottom plate (6) is provided with anchors (15) for anchorage to the overlying concrete, and the concrete layer (18) is cast over the bottom plate (6), and the concrete layer (18) is shaped by taking it through a bordered casting space (1, 5, 10, 13) and compacting it by virtue of a vibrating motion applied on at least one form wall of the casting space, said movement providing a vibrating area (7, 8) on said casting space.
