FIELD: bridge building.
SUBSTANCE: invention relates to bridge construction and can be used to reinforce beams of reinforced concrete span structures of bridge structures. In reinforced concrete bridge span beam, including reinforced concrete block of T-section in form of plate with rib, reinforcement metal frame in the form of tensioned rods ribs arranged in pairs on both sides, a lower reinforcement belt in the form of a channel, enclosing the reinforced concrete block rib from below, and the upper reinforcement belt, the tension rods are combined in pairs at the level of the top of the reinforced concrete block plate with the upper reinforcement belt laid on it in the form of a laid-on monolithic reinforced concrete slab by means of metal shear stops embedded in the upper reinforcement belt.
EFFECT: increased efficiency of bridge span beam reinforcement for bending moment and transverse force perception.
