STEEL-REINFORCED CONCRETE BEAM Russian patent published in 2021 - IPC E04C3/293 

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.
