Abstract (en)
[origin: WO2011015372A1] The curved structural element comprises a flexible arched panel (10), which has two opposite side edges, a plurality of spaced-apart projections (11) extending upwards from the arched panel (10) on at least one of the side edges, and at least one elongate side segment (30), which has an upper and a lower curved longitudinal edge, the lower longitudinal edge facing the arched panel (10). The projections (11) each have a retaining portion (13), which extends inwards at a distance from the arched panel (10) and into which the upper longitudinal edge of the side segment (30) engages with a form fit. Also preferably provided between the projections (11) and the arched panel is a narrow web (3), which extends upwards from the arched panel (10) and with which the projections (11) merge.
