A composite construction element (2) particularly useful for manufacturing building floors, comprises: a) an elongated body (3) made of expanded plastic material, provided with at least one longitudinal channel (4) open on the upper side for receiving a concrete casting (5); b) a reinforcement metal structure (11) of the casting (5), housed in the longitudinal channel (4), associated to the elongated body (3) and having opposite free ends (12) protruding from longitudinally opposite parts of the elongated body (3) for a portion of predetermined length. Advantageously, the composite construction element (2) possesses optimum load bearing characteristics, lightness and flexibility of use. |
