Metal box spans of the bridge

摘要

The utility model relates to bridge construction, in particular to metal box-type bridge spans. The metal box-shaped superstructure of the bridge consists in cross-section of the upper and lower parallel chords, interconnected by supporting vertical walls. There are transverse diaphragms at the ends of the structure. The sheet of the upper chord is reinforced from the inside by longitudinal stiffeners. The vertical walls have round cutouts. The technical result of the presented utility model is the improvement of the box-shaped superstructure, which, when applied, makes it possible to reduce the metal consumption of the structure, reduce its weight and thereby facilitate the delivery, installation and dismantling of the superstructure, as well as reduce the environmental impact on the integrity of the anti-corrosion coating.
