FIELD: road bridges.
SUBSTANCE: invention is related to road bridge spans made of monolithic non-stressed reinforced concrete, consisting of main beams of a T-shaped cross section. The walls of the main beams of the span are reinforced with volumetric frames consisting of longitudinal and transverse working steel reinforcement located behind flat meshes of composite reinforcement, which are located in a protective layer of concrete. The span slab is reinforced with meshes of steel reinforcement, the rods of which are located behind flat meshes of composite reinforcement in a protective layer of concrete.
EFFECT: increasing the strength of the bridge superstructure.
