FIELD: construction.
SUBSTANCE: invention relates to construction and is intended for reinforcement and restoration of functional parameters of ribbed reinforced concrete span structures. In the longitudinal joints of the homogenization of the beams, by combining with the working reinforcement of the plate, by means of connecting elements, duplicating elements are built in the form of metal I-beams or reinforced concrete elements, on the construction of beams similar to those of beams with wireframe or pre-stressed reinforcement. In created structure, due to saturation of reinforcing frames of duplicating elements with transverse reinforcement (bends, clamps), a significant increase in the load-carrying capacity of the transverse force occurs.
EFFECT: reinforcement of the structures of span structures of reinforced concrete bridges, the carrying capacity of which does not correspond to the load class required by the standards.
