Abstract

The invention discloses a connecting device between a fabricated reinforced concrete column unit and a joint. The connecting device comprises a joint connecting plate, a column connecting plate and a concrete-filled steel tube short column, and is characterized in that the joint connecting plate is provided with mounting holes through which vertical longitudinal bars of the joint can pass and are connected with the vertical longitudinal bars; and the column connecting plate is provided with mounting holes through which longitudinal bars of the fabricated reinforced concrete column unit can pass and are connected with the column connecting plate, and the joint connecting plate and the column connecting plate are fixedly connected through the concrete-filled steel tube short column, so that the fabricated reinforced concrete column unit and joint are vertically connected into a whole in a dry mode.

Description

technical field [0001] The invention belongs to the field of prefabricated buildings, in particular to a connection device between prefabricated reinforced concrete column units and nodes. 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 ...
