METHOD OF RECONSTRUCTION AND REINFORCEMENT OF STEEL-CONCRETE COMPOSITE SIMPLY SUPPORTED BRIDGE SUPERSTRUCTURE BY STRAIGHT CABLES Russian patent published in 2017 - IPC E01D22/00 

FIELD: construction.

SUBSTANCE: invention can be used for reconstruction and reinforcement of existing steel-concrete composite simply supported bridge superstructures with spans of up to 63.0 m. Method of reconstruction and reinforcement of a steel-concrete composite simply supported bridge superstructure by straight cables comprises replacement of a reinforced concrete plate, reinforcement of main beams, repair, replacement or increasing the number of devices combining the plate with metal structures, and reinforcement of the main beams walls with additional stiffening ribs, herewith the main beams reinforcement is performed by installation of straight cables located above the lower belts of the main beams, and which after arranging the new reinforced concrete plate remain on the beams and maintain extending beyond the anchor ends of the cables for lifting the cables before completion of the construction works on the bridge superstructure and recovery of the rated capacity of the bridge superstructure.

EFFECT: technical result is more complete usage of reserves of materials strength, reduction of restrictions for vehicles moving under the bridge and improved operating conditions and higher safety of works on metal structures reinforcement.
