<p>The structure (1) has a tack welded lattice beams that are in shape of cage with internal face carrying garnishing plates (4-6) to form a cover. An external face of the cage comprises a suspension unit (11) i.e. helical spring, that elastically deforms the beams in a civil engineering compartment. The garnishing plates are welded with one other with respect to welding lines (7, 8) i.e. vertical welded joints, where the plates comprise gutters (9, 10) to recover drops of water.</p> |
