  • the height H of the cladding element 1 is less than one fifth of the length L of the cladding element first
  • Figure 17 shows, by way of example, a solid concrete slab 2 still cast on with cladding elements 1, similar to the illustration in Figure 9b, although not all details (for example the protective layer 7 or the delaying means 6) are shown for reasons of clarity.
  • Figure 18 shows a representation corresponding to Figure 17 for a concrete slab 2 in sandwich construction.
  • an insulating layer 42 and a further, reinforced concrete layer 43 is provided.

Abstract

L'invention concerne une installation de fabrication d'une dalle de béton (2) garnie d'éléments de revêtement (1), en particulier d'un élément préfabriqué en béton, sur au moins une palette (4), la palette étant mobile entre les postes d'usinage. Dans un poste de coffrage (14), des éléments de revêtement (13) peuvent être appliqués sur la palette (4). Dans un poste de garnissage (15), les éléments de revêtement (1) peuvent être posés sur la palette (4). Dans au moins un poste de bétonnage (16, 30), une couche de béton (5a, 5b) peut être coulée sur la palette (4). L'installation est caractérisée en ce qu'un poste de séparation (17) est prévu pour les éléments de revêtement (1), dans lequel les tailles et/ou les contours des éléments de revêtement (1) peuvent être adaptés, de préférence coupés à dimension, en fonction d'un plan de répartition (26) pour les éléments de revêtement (1). Dans le poste de garnissage (15), les éléments de revêtement (1) adaptés par le poste de séparation (17) peuvent être posés dans la bonne position sur la palette (4) en fonction du plan de répartition (26).
