SPATIAL COATING SLAB Russian patent published in 2018 - IPC E04B1/32 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to the covering of buildings and structures. Spatial slab of a sparse structure covers the upper and lower belts of a curvilinear outline curved in the longitudinal direction, formed from striped long elements alternating between themselves in the belts and connected at the ends. Between the belts intermediate elements are installed in the form of rigidly fixed transverse racks. In this case, the strip long elements are made of curved troughs of the C-shaped profile located in both belts by the walls upwards and contacting at the joints at the ends by the outer surfaces of the shelves, connection being made either bolted through the holes in the shelves, or welded along the contact contour of the shelves.

EFFECT: technical result is improvement of bearing capacity of a large-span coating slab.
