Assembly type concrete building connecting joint

The invention discloses an assembly type concrete building connecting joint. The assembly type concrete building connecting joint comprises a component body, a top plate, a bottom plate and a connecting port, wherein the top plate and the bottom plate are respectively mounted at the top end and bottom end of the component body; the component body is in bolted connection with the top plate; the upper end surface of the top plate is connected with clamping plates; and the bottom plate is connected with clamping groove plates. According to the assembly type concrete building connecting joint, liquid pipe structures communicating with each other after being spliced are used between every two component bodies, and a user can conveniently convey a concrete curing agent from the bottom to the topend of a base column, so that the whole formed concrete base column is comprehensively maintained by utilizing the gravity, and high-pressure equipment such as a water gun is not needed to spray thehigh component bodies, or
