The object of the invention is a large post-tensioned floor bay consisting of a number of prefabricated reinforced-concrete floor elements for making floor structures, as well as a process for the production of floor elements and floor bays. The floor bays are composed of such floor elements, in which channels, optionally closed at the bottom, but open on top in any case, run along the whole length of the elements, the channels being broken by ribs provided with vertically oblong holes. The floor elements are assembled in a way such that the channels join each other. Cables spanning the elements along a straight line are laid in the channels, and the cables are given the required eccentricity at the points where necessary. The cables thus made eccentric are fixed by the channels being filled with concrete. No cable duct tubes are used and a single length of cable can be passed unbroken through several floor bays from wall to wall. Thus one-way or two-way load bearing floor bays can be formed.
