REINFORCED CONCRETE SHELL ROOF Russian patent published in 2011 - IPC E04B7/10 

FIELD: construction.

SUBSTANCE: reinforced concrete shell roof comprises a shell of rectangular shape in plan and supporting flat membranes joined with it along the contour in a monolithic manner. The shell is made as thin-walled and of positive Gaussian curvature. The shell is made with thickening of its section in angular and edge areas. The shell is reinforced with transverse and longitudinal ribs that form an inner contour of the roof. Ribs are made on the inner surface of the shell and are joined to the shell and the membranes in a monolithic manner. The lower contour of ribs relative to the upper one is made with a larger camber.

EFFECT: increased bearing capacity, rigidity, provision of geometric invariability, reduced consumption of concrete and reinforcement.
