The sliding formwork is used, with appropriate hoise mechanisms (11), in the erection of concrete structures which are curved in plan, with variable cross-section in height and variable wall thickness, and an internal core (9) surrounded by an outer wall (1). The sliding formwork (12), of standard type, for the core construction (9) carries a second one (2, 15) for construction of the outer wall (1). The sliding formwork for the outer wall comprises two or more radially adjustable interfacing cantilever beams (15) with form panels (2) fitted to their open ends, to sheath a short section of the wall. These beams and panels can be turned in a helical direction about a scaffolding axis parallel to the axis of the core. |
