Abstract

The utility model provides a coupling beam combining steel plates and high-strength concrete. The combined coupling beam comprises outer coated steel plates and high-strength concrete poured among the outer coated steel plates. According to the coupling beam combining steel plates and high-strength concrete, the anti-shear bearing capacity is improved by arranging the steel plates outside the concrete coupling beam to replace shear reinforcement so as to jointly resist shearing force with concrete. Meanwhile, the high-strength concrete is effectively constrained by the outer coated steel plates to improve the brittleness of high-strength concrete and improve the bearing capacity and deforming capacity of the coupling beam, so that the section of the coupling beam is beneficially reduced while a coupled shear wall structural system meets the demand of anti-seismic performance. In addition, the outer coated steel plates are used as templates, so that the coupling beam is more convenient and quick to construct.
