Zusammenfassung:The utility model discloses a reinforced concrete perforated beam, which comprises a longitudinal reinforcing steel bar (1) and a stirrup (2), and is characterized in that a through steel sleeve (3) is arranged in the perforated beam, and the axis direction of the steel sleeve (3) is perpendicular to the extension direction of the longitudinal reinforcing steel bar (1); section steel is arranged above and below the steel sleeve (3), the extending direction of the upper section steel and the extending direction of the lower section steel are parallel to the extending direction of the longitudinal steel bars (1), and the section steel and the steel sleeve (3) are welded and fixed. By utilizing the characteristic of high strength of the section steel, the problem that the bearing capacity is insufficient due to the fact that a small-section reinforced concrete beam is holed or a general-section reinforced concrete beam is holed is solved, and the bearing capacity is equal to that before holing; during constructi
