SPHERICAL SPATIAL STRUCTURE Russian patent published in 2014 - IPC E04B1/32 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely, to a spherical spatial structure. The spherical structure comprises a frame made of sections of thin-walled profiles connected to form hollow cells. The area of the profile cross section provides for meeting the condition of developing a self-bearing frame without taking into account external loads. A stiff finishing material is fixed to sections of cell profiles, in the form of sheets or boards, on which a solid insulating material is laid. The shape of materials is congruous to the shape of appropriate cells. Grooves between adjacent boards of the insulant for some of their depth are filled with heat insulation material. Free space is filled with a reinforcement frame and concrete. Reinforcement "whiskers" are taken out from concrete, which interact with a volume cellular structure laid onto entire surface of the sphere onto the insulation material, on which concrete is applied.

EFFECT: reduced weight of a spherical structure, simplification of its assembly, increased accuracy of making a spherical surface.
