FIELD: low-rise construction.
SUBSTANCE: invention relates to structures used as ceilings and coatings of residential and public buildings, namely to prefabricated steel-wood floors of buildings.
EFFECT: increased rigidity of the flooring. The prefabricated floor includes load-bearing beams and infill elements. Load-bearing beams are made in the form of bent T-shapes with a lower wooden belt. The infill elements are made of a composite section with a lower wooden belt, with a heater in the middle and an upper light-weight concrete belt, or of oriented chipboard or lamellas.
