The floor structure has prefabricated trough elements (2, 3) enclosing air cells (1a, 1b). A beam grid (4) produced by in-situ concrete by the monolithic construction method is provided between the trough elements (2, 3) and a concrete layer (5) produced on site is formed over the trough elements (2, 3) and the beam grid (4). At the points where the floors and the piers join, the invention provides joints which are suitable, if appropriate, for transferring forces. <IMAGE>
