The invention discloses a fabricated overall connection joint for concrete beams and columns through L-shaped ribs and a using method of the fabricated overall connection joint. The fabricated overall connection joint comprises the prefabricated concrete columns, the prefabricated concrete beams, a round steel pipe, the L-shaped ribs, longitudinal ribs, a prefabricated concrete beam-column joint post-pouring section, a superposed beam upper cast-in-situ area and anti-shear bolts; the prefabricated concrete columns are located at the upper end and the lower end of the prefabricated concrete beam-column joint post-pouring section and connected through the longitudinal ribs and the round steel pipe, and the anti-shear bolts are arranged on the surface of the round steel pipe; and the prefabricated concrete beams are located at the two horizontal ends of the prefabricated concrete beam-column joint post-pouring section, extending parts of the L-shaped ribs are located in the prefabricated concrete beam-column joint post-pouring section, and the superposed beam upper cast-in-situ area is arranged above the prefabricated concrete beams and the prefabricated concrete beam-column joint post-pouring section. The defects that an existing prefabricated concrete beam-column connection joint is complex in construction and high in construction cost, and the quality is difficult to ensure are overcome, deformation during transportation is avoided, and the fabricated overall connection joint is mainly machined in a factory and assembled on site, and is easy to operate, safe and efficient.
Description
technical field [0001] The invention relates to the technical field of building structures, in particular to an integral connection node of an assembled concrete beam-column L-shaped bar and a method for using it. Background technique [0002] Prefabricated buildings have the advantages of fast construction speed and less environmental pollution. At the same time, they can also improve labor production efficiency and quality and safety levels, and promote the deep integration of the construction industry and information industrialization. Therefore, it has developed rapidly in my country's construction market. The prefabricated production of concrete components and the development of various connection nodes will also promote the wide application of prefabricated concrete buildings. [0003] At present, in the common assembled integral joints, steel bars are usually reserved at the ends of precast concrete beams and columns, and sleeve connections are used in the beam-column...
