<p>Floor composed of interconnected flat slabs (2, 4), in particular concrete slabs. At least one groove (18) is formed along each side edge of the slab, running in the lengthwise direction of the side edge or at an acute angle thereto and having side walls essentially at right angles to the side edge, the grooves in the adjoining side edges of the first (2) and the second (4) slab forming a mirror image of each other relative to the interface between said slabs. At least one key element (20) is wedged in said grooves, engaging on the side walls of the two grooves. A floor slab for such a floor comprises a broad strip (6) which is fitted along the side edges and on which one or more pairs of strips (10, 12; 14, 16) are fitted, the facing side edges of the strips of each pair determining a groove. <IMAGE></p> |
