Abstract (en)
[origin: WO9717509A1] The present invention relates to a composite slab comprising as the lowermost element a shaped bottom plate (1) including longitudinal, upward aligned dovetail folds (4) and a cast part (2) of the slab covering the top area of the slab contiguously and the bottom part of the slab by a cross section with trapezoidal core cavities. The tops of the dovetail folds (4) are provided with anchorages (5, 7, 13) capable of preventing the bottom plate from sliding longitudinally with respect to the cast material and core-forming elements (3) are placed lengthwise immediately above the shaped bottom plate (1), between said dovetail folds (4), whereby the core-forming elements together with folds of the shaped bottom plate (1) form said trapezoidal core cavities into said cast part (2). The invention also concerns an advantageous method for the manufacture of said composite slab.
