(57) The structural members obtained in accordance with the improvements of the invention
include bidirectional hollow lightening blocks (3), forming orthogonal ribs (4) and
other shapes, this lightening being completed by a lower reinforcement (5) and another,
upper reinforcement (6) based on unidirectional or bidirectional mesh in both cases,
which, when duly concreted, form lower and upper slabs respectively, and separation
reinforcements (7) between them which define a reinforcement of the ribs which are
formed in the positioning of the hollow lightening blocks (3). The structural member
without girders obtained offers the same resistance to positive and negative moments,
and the meshes which constitute the lower (5) and upper (6) reinforcements are simple
meshes of conventional industrial fabrication.
