STEEL-AND-CONCRETE FRAME OF MULTISTORY BUILDING Russian patent published in 2002 - IPC

FIELD: construction industry. SUBSTANCE: invention specifically refers to steel-andconcrete supporting frames of buildings with different number of floors erected in various regions, seismically risky regions included. Steel-and-concrete frame includes steel columns 1, flat prefabricated plates 2, steel-and-concrete supporting beams 3, bond beams 4 and steel joining members which make columns and beams in each floor physically integral with single spatial structure by means of flat joining members and bolts. Frame also includes means reinforcing beams and columns, concrete filling columns, beams and joining members. Groups of prefabricated plates interjoined in each group over sides by interplate joints are arranged in floor with butts facing steel beams. Monolithic reinforced concrete tie bars 5 are located between groups of plates over their length, butts of plates are integrated with beams with the use of monolithic filling concrete in single steel-and-concrete flat structure. From beneath plates and beams are united by means of lower longitudinal fittings of monolithic tie bars. EFFECT: reduced usage of metal, decreased labor input to erection of building, raised supporting capacity and diminished mass of structures. 8 cl, 19 dwg
