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.
Description
Technical field: [0001] The invention relates to a reinforced concrete assembled integral frame with U-shaped steel vertically connected and a construction method thereof, which belongs to the field of construction engineering concrete frame structure technology and construction. technical background: [0002] Reinforced concrete prefabricated integrated frame structure is an important direction for the future development of building industrialization. It has the advantages of short economic cycle, high quality prefabricated components, less on-site wet work, less environmental pollution, faster construction progress, lower labor intensity of workers, and is conducive to energy saving and reduction. Consumption and environmental protection and other advantages. This structural system has been widely used in developed countries and has become the main form of new buildings in some countries. The connection technology is the core issue of the reinforced concrete prefabricated...
