<p>The hollow or solid section packing (3) has at least two transverse ribs (4,5) with a slight longitudinal dimension with respect to that of the packing and the packing sits on the beams via surfaces (4a,5a). The ribs are separated by zones (Zs) of greater longitudinal dimension than the ribs and both rib and zone have inclined faces on part of their heights. Because the bearing is not continuous, the concrete forming the slab can be vibrated down between the ribs until it is in contact with the flange of the support beam.</p> |
