An assembled reinforced-concrete beam that includes steel part as two vertical walls connected at beneath by flange made of slab, at above – by vertical traverses, and at ends – by supporting ribs (slats), and reinforced-concrete section between walls. The lower flange of the beam on sides has cantilevers for support of floor deck, and reinforced-concrete section is placed along the beam axis with one armature frame that makes possible its concreting in one operation, due to that building height of floor is decreased as well as labor consumption and time for making the beam. |
