Method and system for manufacturing hollow reinforced concrete modular elements and element obtained therefrom

A method of manufacturing a hollow, monolithic, concrete modular element, the method comprising the steps of:

• concreting first and second side walls in first and second formworks arranged horizontally;
• rotating the first and second horizontally arranged formworks while said concreted side walls are in a partially set state so as to arrange the side walls vertically on opposite sides of a third formwork arranged horizontally, the vertically arranged side walls having lower ends constituting part of said third formwork;
• concreting a floor slab in said third formwork after said rotating and before the side walls have completely set, the concreted floor slab forming lower joints with said side walls;
• positioning a fourth formwork arranged horizontally between the vertically arranged side walls at a height suitable for concreting a ceiling slab, the vertically arranged side walls having upper ends constituting part of said fourth formwork;
• concreting a ceiling slab in said positioned fourth formwork after concreting the floor slab and before the side walls and floor slab have completely set, the ceiling slab forming upper joints with said side walls;
• and
• forming said monolithic element by concurrently setting the concreted floor and ceiling slabs together with the partially set side walls.
