Patent

CA 2417823

A method and system is provided for constructing large continuous concrete slabs without using conventional shrinkage control joints. The system comprises a grid of closely spaced crack inducers (2) arranged relative to a concrete-pouring surface and adapted to be covered by concrete. The inducers (2) are connected to one another with connectors (10). The inducers (2) are of a size, shape and spacing to promote fine cracking in the vicinity of the inducers (2) throughout the slab when the concrete sets.

L'invention se rapporte à un procédé et à un système de construction de grandes dalles continues en béton sans recours à des joints classiques de régulation des retraits. Ce système comporte une grille d'inducteurs de fissures (2) à faible distance les uns des autres, disposés relativement à une surface de coulage du béton et conçus pour être recouverts de béton. Ces inducteurs (2) sont reliés les uns aux autres par des connecteurs (10). Ces inducteurs (2) présentent une taille, une forme et un écartement favorisant la formation de fissures fines au voisinage des inducteurs (2) sur l'ensemble de la surface de la dalle lors de la prise du béton.
