COMPOSITE STRUCTURE BASED ON SPHERICAL ICOSAHEDRON Russian patent published in 2024 - IPC E04B1/32 

FIELD: construction.

SUBSTANCE: invention relates to prefabricated spherical structures. Prefabricated structure based on spherical icosahedron is made in form of triangular network, from which through pyramidal panels in the form of hexagons and regular pentagons can be formed connected from triangles. Base nodes and panels centers nodes are located at intersections of additional axes of meridians and parallels, and also boundaries of repeating segments making up one sixth of faces of spherical regular icosahedron. All panels are fully or partially located within said spherical triangular segments. Prefabricated structure is two-belt and comprises interconnected pyramidal or spatial outlines of panels with only a flat base. Hexagonal and pentagonal panels are made with base nodes circumscribed by circles with their radii from the centers of the panels lying on the sphere, note here that centers nodes are arranged at intersection of additional axes and segment boundaries. Nodes along the contour of the panels are formed by a network of circles circumscribing the panels, and are located at the points of intersection of the corresponding three adjacent circles, in addition, hexagonal panels located on additional axes in the form of meridians on one parallel have equal radii-braces and lengths of ribs.

EFFECT: higher reliability of the structure.
