Abstract (en)

[origin: EP0814221A1] A procedure for making a concrete mast using at least two components (1, 2) which fit one inside the other consists of forming shuttering from the two components, fitting lengthwise and transverse reinforcing elements (3, 4) and a one-piece mould with a double base (8, 9) and two collars (6, 7), and filling with concrete. The concrete is vibrated and/or centrifuged, with the gap left between the outer surface of the mould and the inner surface of the female component filled with a self-hardening mortar after centrifuging. The mould is removed once the concrete has set, e.g. using a nut and bolt mechanism. The lengthwise reinforcing members can be in the form of rods which are sectioned after casting, or pre-stressed cables.
