FIELD: bridge building, particularly railroad bridge span structure erection of precast panels.
SUBSTANCE: bridge panel includes steel sheet, supports made as vertical sheet plates with slots for receiving reinforcement welded to the sheet and embedded in it. Panel has rods inserted in plate orifices in addition to the lower reinforcement. Rod axes are located above steel sheet surface and spaced a distance from it. The distance is determined from a given relation. Steel sheet may be pressed to steel bridge beam belt during welding of the supports.
EFFECT: increased safety against failure and durability of panel connection with steel bridge beam belt, which are equivalent to that of cast-in place panels.
