FIELD: bridge construction.
SUBSTANCE: invention can be used in the construction and restoration of quickly installed bridges and temporary crossings of various lengths, load capacity and functionality. The prefabricated bridge structure contains longitudinal lattice trusses connected to each other by transverse lattice inserts and diagonal cross braces. The longitudinal trusses are made with folding upper and lower chords, inside of which twisted cables are stretched. The longitudinal trusses are made with additional components to allow them to be adjusted in length. An additional support post with a groove connector and a support platform for fixing transverse lattice inserts is installed on each connecting node of the longitudinal trusses. Orthotropic road pavement slabs with a corrugated surface are installed on top of the upper belt. Inside the coating slabs, twisted torsion bars are laid in tubes.
EFFECT: possibility of repeated use of the structure while speeding up its construction.
