U-shaped steel vertical connection assembled integral type frame and construction method thereof

The invention discloses a U-shaped steel vertical connection reinforced concrete assembled integral type frame and a construction method thereof. The frame comprises a reinforced concrete fabricated column (1) with a short beam section (3), a reinforced concrete fabricated beam (2) and U-shaped steel (4). The end, with the short beam section (3), of the reinforced concrete fabricated column (1), is provided with a first vertical bolt hole (51). A second vertical bolt hole (52) is formed in a web plate of the U-shaped steel (4), the two ends of the reinforced concrete fabricated beam (2) are provided with third vertical bolt holes (53) respectively, the reinforced concrete fabricated column (1) and the reinforced concrete fabricated beam (2) are connected through the U-shaped steel (4) and a vertical friction type bolt (6), an engineered cement-based composite material (7) is poured on the connection area, and therefore the assembled integral type frame is formed. The assembled integral frame has the advantages that internal force transfer is clear and reliable, stress is simple and reasonable, the construction method is convenient, fast and efficient, the overall performance is good, and the anti-seismic property is good.
