STRUCTURAL SPATIAL WORK Russian patent published in 2011 - IPC E04B7/08 E04B1/32 

FIELD: construction.

SUBSTANCE: structural spatial work comprises a flexible dome-shell with ties and a system of stiffening elements between them. The dome-shell is outlined in a cross section along a circumference arc. Longitudinal mesh trusses are installed under the dome-shell and fixed with it and the ties. Trusses are supported at the ends onto bearing structures. Upper and lower units of neighbouring longitudinal trusses are connected to each other by means of transverse bracing-rod elements with formation of a supporting structure with transverse trusses.

EFFECT: increased stiffness of a spatial work, reduced material intensity, expansion of used materials range, possibility of application for small, middle and large spans without usage of runs.
