FIELD: construction.
SUBSTANCE: invention relates to construction and can be used in production of steel beams, bearing structures of coatings and floors of buildings. In composite reinforced concrete beam including steel beam, steel stops and reinforced concrete flooring, supports are made of expanded metal and attached to upper beam of beam on contact surfaces, and lengthwise supports have wavy or shaped shape.
EFFECT: technical result consists in improvement of carrying capacity of composite steel beam and providing joint operation of stops with steel beam.
