FIELD: construction.
SUBSTANCE: invention relates to the field of construction and can be used as beams of ceilings and coatings of residential and public buildings. Pre-stressed steel concrete beam comprises a steel profile of a single or composite I-section having anchor assemblies, longitudinal pre-stressed reinforcing bars, end ribs and embedment concrete. End faces of the profile are welded to the end edges with holes for removable tensioners, attached to the anchor plates located on the inside of the end ribs.
EFFECT: invention is aimed at increase in the overall load-bearing capacity of the concrete beam by rationally transferring prestress to concrete.
