The invention discloses an assembly-type connection node for an end lap-joint beam and column. An annular lap-joint plate is of a square structure, four limit blocks are fixed to the four side faces of a square steel pipe column in the circumference direction in sequence, and all first fixing plates and all second fixing plates are crosswise fixed to the four side faces of the square steel pipe column in the circumference direction in sequence; the two first fixing plates and the two second fixing plates form a sleeve-shaped structure, the sleeve-shaped structure sleeves the square steel pipecolumn, one first fixing plate corresponds to one limit block, and one second fixing plate corresponds to one limit block; first limit grooves are formed in the first fixing plates and the second fixing plates, first limit grooves in the first fixing plates sleeve the corresponding limit blocks, and first limit grooves in the second fixing plates sleeve the corresponding limit blocks; the lower ends of the first fixing plates and the lower ends of the second fixing plates are located on the annular lap-joint plate, and steel beams are fixed to the first fixing plates and the second fixing plates. According to the node, welding in the construction site can be avoided.
