SPHERICAL SHELL Russian patent published in 2020 - IPC E04B1/32 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular to structures of spherical shells. Spherical shell consists of rod elements and hinges forming fragments of flat grid with possibility of its transformation into shape of spherical surface of rotation. Fragments of flat grid consist of three spatial six-link mechanisms, and rod elements are links of spatial six-link mechanism. Enclosure is formed of four sectors, which in turn are formed of two fragments consisting of three spatial six-link mechanisms, which are hinged in rhombus, with possibility of being fixed in design closed position. Enclosure can consist of five sectors, which in turn are formed of four fragments consisting of three spatial six-link mechanisms, which are hinged in a parallelogram, with possibility of being fixed in the design closed position.

EFFECT: technical result is higher strength of shell.
