FIELD: building structures.
SUBSTANCE: invention relates to building structures, namely to floor and roof beams. The hybrid beam contains steel-fiber-reinforced concrete fixed formwork profiles consisting of walls and chords, cast-in-place concrete and, if necessary, regular reinforcement. Steel-fiber-reinforced concrete profiles of fixed formwork are made of concrete-matrix with fiber reinforcement with steel fibers. A steel-fiber-reinforced concrete profile of fixed formwork can be provided with an outer layer made of concrete, dispersed-reinforced with non-metallic fibers. The steel-fiber-reinforced concrete profile of fixed formwork (1) can be provided on the inside with protruding steel fibers.
EFFECT: reduction of material consumption, labor intensity of manufacturing, increase in the operational characteristics of the beam.
