Abstract
A mast section (1) including a wall includes two tubular mast elements (14) stacked and arranged edge to edge at a joining plane (P), each element (14) comprising two wall segments (16) connected by segment connectors (26) extending along the longitudinal edges of the segments (16). The mast section (1) comprises element connectors (36) each extending across and connecting the elements (14) together. The element connectors (36) are arranged either on the inner surface (12) and outer surface (13) of the wall and the segment connectors (26) are arranged on the other surface, each element connector (36) extending at least partially opposite at least one of the segment connectors (26) in a radial direction of the mast section (1) such that the wall is placed between said element connector (36) and the segment connector (26).
