<p>The set of building components for an electric switchgear station comprises prefabricated concrete units with an external wall slab. The components (1-3) are in the form of a rectangular troughed or ribbed base slab (1.1), with reinforcing ribs (3) projecting from one face. On some of these, in part of the corner area, and in or against the ribs' line, there are vertically projecting sidewalls (7, 9), or in other cases support columns (5). The degree of protrusion of sidewalls and columns is pref. the same on each element, but may vary between elements. Standard sets can be used for construction of switchgear stations adapted to a wide variety of needs.</p> |
