Reinforced concrete pre-embedded type steel beam support joint and construction method

The invention discloses a reinforced concrete pre-embedded type steel beam support joint, comprising a support and a concrete beam, the support comprises a main body, multiple rib plates, multiple short-cut steel bars, multiple long-cut steel bars and multiple sleeves; each rib plate is fixed on the main body; the multiple short-cut steel bars and the multiple long-cut steel bars are respectivelyfixed at the end parts of the rib plates and are arranged at intervals; one sleeve is fixed at the free end of each short-cut steel bar and each long-cut steel bar; and the short-cut steel bars and the long-cut steel bars are connected with longitudinal steel bars of the concrete beam through the sleeves. Real-time processing on a construction site is realized, the integrity of the steel structuresupport joint and the concrete beam is ensured, the construction procedure of the component is simplified, the structural safety performance of the joint is enhanced, possible breakage and severe deformation of the concrete b
