A three-dimensional cylindrical rod cover includes long and cross ribs and downward diagonal ties placed on the circular surface of the cover, spring-supported diaphragm formed with props and braces, one angle contour unit fixed against linear displacements, three other angle contour units provided with linear links in vertical and horizontal directions, the other contour units fixed against linear displacements by vertical. Besides that, a system of guide elements of tubular profiles is included, the braces are in shape of arc, at that each brace is in tension, and the number of spring-supported diaphragms depends on the number of cells in direction of the generatrix. |
