Main and additional round sector shells have the same or different dimensions (outer radius, thickness, central angle) and are connected one to another by means of locking members to create symmetric or asymmetric closed outline. The body has at least one longitudinal stiffening rib arranged within the closed outline and distributed along length thereof. Both locking members to be secured to the body are made as male or female parts.
