BUILDING COVER Russian patent published in 2014 - IPC E04B7/00 

FIELD: construction.

SUBSTANCE: building cover includes bearing elements, for instance, in the form of light trusses installed with equal pitch 1. Panels of profiled deck are laid onto bearing elements. Panels of the profiled deck via one step of bearing elements are laud in accordance with the double-cantilever pattern, and non-standard precast sheets of profiled deck are laid onto the ends of cantilevers. At the same time the length of cantilevers equals to: $$a=\left(\frac{\lambda -\sqrt{{\lambda }^2-\lambda }}{4}\right)\cdot l$$ , here l - pitch of bearing elements; λ=(W₂/W₁+1), where W₁ - rated resisting moment of profiled deck with pressed narrow shelves; W₂ - the same with pressed wide shelves.

EFFECT: reduced consumption of steel onto cover elements.
