Beschreibung
Zusammenfassung:	construction engineering; construction of bridges and other transport structures on highways. SUBSTANCE: structure has span beams with anchors, corrugated steel deck placed on beams, and reinforced concrete slab. Novelty is that anchors are made in the form of reinforcing projections whose length from top beam ledge is at least 1.1 times greater than height of steel deck corrugation; steel deck is dovetail- section structure; reinforcing projections are passed through corrugation slabs filled with concrete and joined to bottom ledge of its reinforcement; mentioned ledge is spaced through distance equal to 0.5-1.5 of corrugation height from bottom surface of slab. Span can be made with rounding on top with built-up beams arranged along chords. EFFECT: improved reliability of composite span. 3 cl, 2 dwg
