A pre-fabricated concrete slab system and method have matching rectangular slabs with cooperatively fitting male and female type connectors (26, 32, 106, 118) which fit adjacent to each other in a checkerboard fashion. The slabs (10, 12, 100) include spaced reinforcing rods (18, 36, 102, 104) extending longitudinally and transversely therethrough. In at least some of the slabs, the rods' distal ends protrude outwardly away from one or more side edges of the slabs to form a plurality of male connectors (26, 106). Correspondingly, at least some of the slabs include a plurality of corresponding female sockets (32, 118) on one or more sides thereof, each female socket receiving a corresponding male connector when dropped therein. Through interconnection of corresponding female sockets and male connectors by steel reinforcing bars extending in both the longitudinal and transverse directions, a continuous tension reinforcement is established between adjacent slabs in both the longitudinal and transverse directions.

Un système de dalle en béton manufacturé et un procédé associé présentant des dalles rectangulaires correspondantes ayant des connexions de type mâle et femelle de coopération (26, 32, 106, 118) qui s'adaptent adjacentes les unes aux autres en damier. Les dalles (10, 12, 100) comprennent des tiges de renfort espacées (18, 36, 102, 104) s'étendant longitudinalement et transversalement. Dans au moins certaines des dalles, les extrémités distales des tiges font saillie vers l'extérieur et s'éloignent d'un ou plusieurs des bords latéraux des dalles afin de former une pluralité de connexions mâles (26, 106). Au moins certaines des dalles comprennent une pluralité de supports femelles correspondantes (32, 118) sur un ou plusieurs cotés, chaque support femelle recevant une connexion mâle correspondante lors de son insertion. Grâce à l'interconnexion des supports femelles et des connexions mâles correspondants par des barres de renfort en acier s'étendant à la fois dans les sens longitudinaux et transversaux, un renfort de tension en continu est établi entre des dalles adjacentes dans les sens longitudinaux et transversaux.
