A lightweight slab including two main parallel reticular reinforcements (5) (6) separated by secondary reinforcements and arranged to form a double diagonal, a single diagonal or to be perpendicular in relation to the main reinforcements. All of the reinforcements are embedded in a volume of concrete filling which covers and protects such reinforcements and which is defined by a suitable formwork or mould which creates voids in a hypothetical prismatic volume and which is formed by hollow prismatic or truncated-pyramid-shaped volumes with smooth edges and vertices that improve structural strength and facilitate the extraction of the moulds. The filling includes open holes (4, 3) in those portions that do not interfere with the secondary and main reinforcements to form a succession of nodes connected at the top and bottom by holes that can be accessed from the lower and/or upper level (4) and, internally, hollows (2) connected by side holes (3).
A lightweight slab or similar structural element that can receive facilities which will be extended through the slab being easily accessible and comprising:
A formwork or mould wherein the formwork or mould is recoverable and comprising:

A formwork or mould lightweight slab the formwork or mould that defines the structure inner holes can be recovered and is formed by semi-sphere-shaped plates (13) that fit into each other to define the said hole wherein the plates (13) fit in the next ones to define a network of channels and can be extracted either from the top or the bottom through the hole that links at least one of the surfaces with said holes and, in case of a one-way structure formwork, the one-way structure formwork is defined by semi-boxes (11) each of which form a lateral face of the structure and half of the upper and bottom faces and embeds in a flange suitable polyhedral area a polyhedral protrusion that conforms the existing window of the structure.
A formwork or mould wherein the formwork or mould that defines the structure inner holes is a permanent formwork that comprises pieces (18) made of a synthetic material, mortar or ceramic, each one forming, either alone or in conjunction with other pieces, each hole with its link to the adjacent hole which defines a network of inner channels.
A formwork or mould wherein the formwork or mould consists of two thin plates (23) (24) made of synthetic or rubber material and conveniently joined together so that, once they are inflated and come apart, they define the adequate inner holes and the spaces left for the structural nodes.
A formwork or mould wherein the formwork or mould is formed by inflatable balloons (25) disposed in reticular layout which connect laterally when inflated and are related by conducts attached to a pumping system (26) which allows, once inflated, the construction of a structure on top of them or when they are going to be deflected the extraction can be easily done.
