Prefabricated concrete beam column connecting joint structure and construction method

Abstract

The invention provides a prefabricated concrete beam column connecting joint structure and a construction method. The connecting joint structure comprises a beam end steel connector, a column top end steel connector, and a column bottom end steel connected; the beam end steel connector is partially located in the end of a prefabricated concrete beam and partially located outside the end of the prefabricated concrete beam; the column top end steel connector is partially located in the top end of a prefabricated concrete column and partially located outside the top end of the prefabricated concrete column; the column bottom end steel connector is partially located in the bottom end of the prefabricated concrete column and partially located outside the bottom end of the prefabricated concrete column; the beam end steel connector located outside the end of the prefabricated concrete beam and the column top end steel connector located outside the top end of the prefabricated concrete column are fixedly connected on a construction site; and the column top end steel connector located outside the top end of the prefabricated concrete column and the column bottom end steel connector located outside the bottom end of the prefabricated concrete column are fixedly connected on the construction site. Non-support construction of prefabricated concrete beams and columns can be achieved, on-site wet operation is avoided, the construction period is effectively shortened, and meanwhile the advantages of good deformation and energy dissipation capacity of a steel structure during an earthquake can be exerted through reasonable design.

Description

technical field [0001] The disclosure relates to the field of prefabricated structures, in particular to the structure and construction method of prefabricated concrete beam-column connection nodes. Background technique [0002] At present, the commonly used prefabricated frame structure system mainly includes prefabricated concrete frame structure and steel frame structure. The core of the prefabricated frame structure system is the beam-column joint structure. [0003] For prefabricated concrete frame structures, prefabricated columns and composite beams are generally used, and post-cast concrete is generally used for beam-column connection nodes, and temporary supports and formwork are required on site. The construction cost of this system is relatively low, but the on-site workload is large and the construction period is long. [0004] For steel frame structures, the frame columns generally adopt rectangular steel pipe columns or H-shaped steel columns, and the steel b...
