Composite floor structure with a protruding bar upper portion in a floor element groove

A floor structure comprising:

• a plurality of composite construction elements arranged side by side and comprising:
• an elongated body made of expanded plastic material provided with an upper face;
• at least one reinforcing section bar longitudinally extending in said elongated body and having an upper portion protruding from the upper face of said body;
• a substantially reticular reinforcement metal structure of a concrete casting, supported by the upper portion of said at least one reinforcing section bar at a predetermined distance from the upper face of said elongated body made of expanded plastic material;
• a plurality of floor elements made of expanded plastic material supported by said composite construction elements and arranged at a predetermined distance from one another so as to define a plurality of transversal channels and a plurality of longitudinal channels adapted to house the concrete casting;
• wherein said substantially reticular metal structure comprises a plurality of transversal reinforcement elements of the casting housed in said transversal channels;
• and
• wherein said transversal reinforcement elements of the casting are supported by the upper portion of said at least one reinforcing section bar.
