The reinforcement elements are arranged in planes of facets of the girth-rail body at right angle, with formation of square or rectangular cells, those vertical and long horizontal reinforcement elements of spatial frame as reinforcing mesh are placed in parallel to the facets of the girth-rail body and at same distances from the outer surfaces of those. |
