FIELD: construction.
SUBSTANCE: invention relates to the field of construction and can be used in the manufacture of steel-reinforced concrete beams of load-bearing structures of coatings and floors of buildings. In a steel-reinforced concrete beam, including a reinforced concrete flooring and a steel beam, anchors of a composite section from a bundle of thin twisted or parallel rods are attached to the upper chord by welding, the upper ends of which are bent in half rings at different levels, the lower ends are bent with the inverted letter "L" and in contact with the upper chord beams are welded by resistance welding.
EFFECT: invention increases the bearing capacity of the steel-reinforced concrete beam and ensures the joint operation of the anchors with the steel beam.
