Abstract

The invention discloses a fabricated reinforced concrete beam-column joint. The fabricated reinforced concrete beam-column joint comprises vertical longitudinal bars, transverse longitudinal bars and at least two adjacent beam unit connecting ends, wherein the vertical longitudinal bars can pass through mounting holes of a vertical connecting device and are connected with a vertical joint connecting plate, so that the top surface or the bottom surface of the fabricated reinforced concrete joint is matched with the vertical joint connecting plate; and the transverse longitudinal bars can pass through mounting holes of a transverse connecting device and are connected with a transverse joint connecting plate, so that the beam unit connecting ends are matched with the transverse joint connecting plate.

Description

technical field [0001] The invention belongs to the field of prefabricated buildings, and in particular relates to a prefabricated reinforced concrete beam-column node. Background technique [0002] The connection methods along the building height direction in the existing prefabricated building field mainly include grouting sleeve connection technology, reserved hole grout anchor lap connection technology and cast-in-place belt connection. Among them, the grouting sleeve connection is widely used in actual engineering and the construction technology is relatively mature, but there are still problems such as on-site docking difficulties, difficulty in ensuring the quality of grouting in the sleeve, and difficulty in later quality inspection; in addition, the diameter of the sleeve is relatively small. Large, in order to ensure the position of the longitudinal reinforcement in the reinforced concrete column, the thickness of the concrete cover outside the sleeve is relatively...
