The subject of the invention is the creation of a floor formwork system making it possible to cast on site a floor of any size. The same formwork tool makes it possible to cast a floor surface area of between 0.8 m<2> and 22 m<2>, regardless of the shape of the floor to be produced. It is designed so that it may be moved manually in the building being constructed and may therefore pass through the openings made in the walls for doors as well as in the corridors. It is built according to Figure 1 showing the system in the moving position, but without the beams 14 and their extensions 15. A carriage 1 with wheels 2, adjusting jacks 3, a central column 4 with rack guides 5, gearing case 6 and crank 7, this assembly forms the lower part of the system. The upper part may move vertically by means of the rack 9 fixed to the upper column 8 supporting the rectangular formwork-forming frame 10. The hinged parts 11 with their extensions 13 are hinged to this frame and are held horizontally by the props 12 when the formwork is opened out. The device according to the invention is particularly intended for producing floors which are cast at present using conventional formwork or using permanent formwork based on concrete preslabs. <IMAGE>
