FIELD: construction.SUBSTANCE: spherical shell comprises hexagonal panels, different-type marks of which are identically located within the sectors having a common top on the panel made in the form of a regular hexagon. Irregular hexagonal panels with decreasing sizes from the top of sectors to periphery, create identical rows of different-type marks turned within each sector by the same angle relative to the axis passing via the centre of the sphere and perpendicular to the plane of symmetry of the sector. Within the limits of sectors making 120°, hexagonal panels are made with a bearing frame from ribs-crossbars and nodal elements, and also with angles circumscribed with circumferences with their radii from centres of panels, which lie on the sphere. Angles of three adjacent panels are connected and located in the point, where the nodal element is located. Panels in the form of a regular hexagon with centres on axes of sectors are made with one radius; panels in the form of irregular hexagons partially or fully arranged within sectors, equidistant from axes of sectors, have equal radii-ribs and lengths of sides-ribs.EFFECT: simplified manufacturing and assembly of shells.3 cl, 8 dwg |
