Title (EN) COMPOSITE SLAB, A PROFILE PLATE THEREOF AND A METHOD FOR PRODUCING A COMPOSITE SLAB
(FR) DALLE COMPOSITE, PLAQUE PROFILEE POUR CETTE DALLE ET PROCEDE DE PRODUCTION D'UNE DALLE COMPOSITE
Abstract:
(EN) 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.
(FR) La présente invention concerne une dalle composite comprenant, comme élément inférieur, une plaque de fond profilée (1) qui présente des plis longitudinaux (4) en queue-d'aronde alignés vers le haut et une partie coulée (2) qui couvre la zone supérieure de la dalle de façon contigüe et sa partie inférieure par une section transversale présentant des cavités en alvéoles trapézoïdales. Les sommets des plis (4) en queue-d'aronde sont pourvus d'ancrages (5, 7, 13) qui empêchent la plaque de base de glisser longitudinalement par rapport au matériau coulé, et des éléments (3) formant des alvéoles sont placés en longueur, immédiatement au-dessus de la plaque de base profilée (1), entre les plis en queue-d'aronde (4). Les éléments formant les alvéoles forment, avec les plis de la plaque de base profilée (1), les cavités en alvéoles trapézoïdales dans la partie coulée (2). L'invention concerne également un procédé avantageux de fabrication de cette dalle composite.
