A ballast block deck system includes a plurality of ballast blocks (12) laterally positioned to form an elevated deck (14) on an existing roof structure. Each block (12) has a predetermined thickness and multiple corner portions (22). A pedestal assembly (30) is located diretly beneath the corner portions (22) of adjacent ballast blocks (12) to space and support the blocks (12) a spaced distance above the existing roof surface. The pedestal assembly (30) includes a support plate (34) having a support surface (40) for supporting the corner portions (22) thereon, a cornercap (44) which removably attaches the cornercap (42) to the support plate (34) and cornercap (42) of the pedestal (30). Preferably, the corner portions (22) of the ballast blocks lies flush with the top surface (16) of the ballast blocks (12), and preferably, the corner portions (22) have a groove (20) for cooperatively engaging a flange (56) depending from the cornercap (42) so that lateral movement of the blocks (12) relative to the pedestal (30) and to other blocks (12) is prevented.
L'invention porte sur un système de réalisation de plates-formes de blocs de lest comportant un ensemble de blocs (12) positionnés latéralement de manière à former une plate-forme surélevée (14) sur une toiture existante. Chacun des blocs (12) présente une épaisseur prédéterminée et plusieurs coins (22). Un socle (30) placé directement sous les coins (22) des blocs contigus (12) les porte et les maintient à une certaine distance au-dessus de la surface existante du toit. Ledit socle (30) comporte une plaque-support (34) présentant une surface support (40) portant les coins (22), un boulon (44) fixant réversiblement le couvre-coins (42) à la plaque support (34), et le couvre-coins (42) au socle (30). Les coins (22) des blocs, qui affleurent de préférence à la surface supérieure (16) des blocs, présentent une rainure (20) s'engageant dans des ailes (56) solidaires du couvre-coins (42), pour empêcher les mouvements latéraux des blocs (12) par rapport au socle (30) et par rapport aux autres blocs (12).
