A flooring of pre-stressed deck construction has an elongate decking (10) extending along the flooring, the decking (10) having an upwardly facing asymmetrically profiled channel formation (11) whereby the neutral axis is above a central horizontal plane. A tension rod (40) extends between stressing brackets (20) secured to each end of the decking (10) and is located below the neutral axis of the decking (10) along the length of the decking (10). Each stressing bracket (20) is secured to upwardly extending sidewalls (13) of the channel (11) above the tension rod (40). The decking (10) is attached to the girder framework (44) of a building. Since the tension rod (40) is below the neutral axis of the decking (10), the bending stress applied to the decking (10) is positive, causing upward arching of the decking (10). This is stress relieved when the concrete flooring (53) is applied to the decking (10). Since the attachment of the stressing brackets (20) to the decking (10) is above the tension rod (40), there is no negative bending stress applied to the ends of the decking (10). In fact, the positive bending stress applied is enhanced by this configuration.

Selon la présente invention, un revêtement de sol de construction de terrasse précomprimée comprend un platelage allongé (10) s'étendant le long du revêtement de sol, ledit platelage (10) présentant une formation de canal profilée asymétriquement faisant face vers le haut (11), ledit axe neutre se trouvant au-dessus d'un plan horizontal central. Une tige de tension (40) s'étend entre des supports de contrainte (20) fixés sur chaque extrémité du platelage (10) et elle est située en-dessous de l'axe neutre du platelage (10) sur la longueur du platelage (10). Chaque support de contrainte (20) est fixé sur des parois latérales s'étendant vers le haut (13) du canal (11) au-dessus de la tige de tension (40). Le platelage (10) est attaché au cadre de poutre (44) d'un bâtiment. Comme la tige de tension (40) se trouve au-dessus de l'axe neutre du platelage (10), la contrainte de courbure appliquée au platelage (10) est positive, ce qui provoque une cambrure du platelage vers le haut (10). Cette contrainte est retirée, lorsque le revêtement de sol en béton (53) est appliqué au platelage (10). Etant donné que la fixation des supports de contrainte (20) sur le platelage (10) est située au-dessus de la tige de tension (40), aucune contrainte de courbure négative n'est appliquée aux extrémités du platelage (10). En fait, la contrainte de courbure positive appliquée est améliorée par ce modèle.
