A concrete floor is constructed at least partially about a supporting hollow core tower. The hollow core tower, which preferably includes a rectangular section, closely conforms to the border of the floor at the elevational outside section where the floor is fastened. The floor at its edge, immediate the tower sides, is provided with beam defining folds preferably bent down at an angle in the range of 30° to 60° from the major plane of the floor. At least one beam at each tower and at least two non-linearly aligned beams at each floor are nested at the floor-tower interface, typically below the major supporting surface of the floor. The tower sidewall at the floor is transpierced and threaded to receive a tension support member angularly depending downwardly and outwardly from the inside of the tower to the outside of the tower. Likewise and in registry with apertures transpierced in the tower, the beam at the tower inside includes apertures extending angularly downward. Those apertures extend through the floor fold at the tower outside. When the floor is raised to its full supported height, bolts are threaded through tower sidewalls, horizontal beams and slab folds and fastened at opposite ends to receive tension. The resultant fastening provides a vertical support to the floor through and at the beam as well as a friction support of the floor to the tower sidewall.
