SUBSTANCE: vaulted covering has comprises rectilinear covering surface generator and is supported at longitudinal ends. The covering comprises panels with ribs formed along panel perimeters, tightening means and flexible ties arranged inside covering vault. The panels are articulated in covering width direction. The flexible ties are made as three-dimensional tie system including inclined bars and additional bars connected with each other. Inclined bars are connected one to another and to ends of each second panel along covering length so that the bars create rhombic tie system in plan view. The inclined bars are also connected to additional bars and define triangular grid with posts located in connection points thereof. The posts rest upon ribs in panel centers. Tightening means are arranged in vertical planes defined by points of inclined bar connection between each second panel.

EFFECT: increased rigidity and stability due to creation of three-dimensional tie system.
