Abstract

The invention discloses a dry-connected fabricated reinforced concrete column unit. Outward-extending longitudinal bars at the upper end and the lower end of the fabricated reinforced concrete column unit can be connected with connecting devices through mounting holes of column connecting plates, and the connecting devices at the upper end and the lower end of the fabricated reinforced concrete column unit can be connected with vertical longitudinal bars of joints at the upper end and the lower end through mounting holes of joint connecting plates, so that the fabricated reinforced concrete column unit and the joints are vertically connected into a whole in a dry mode.

Description

technical field [0001] The invention belongs to the field of prefabricated buildings, and in particular relates to a dry-connected prefabricated reinforced concrete column unit. 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 r...
