Box type beam and column connecting assembly type node preparation technology and node thereof

The invention relates to a box type beam and column connecting assembly type node preparation technology and a node thereof. The node comprises a box type beam, a vertical column and a bracket, the end of the box type beam forms an H-type end through transition, the H-type end comprises an end upper flange, an end lower flange and an end web plate; the vertical column is connected with the bracketthrough welding, and the bracket is an H-type bracket which comprises a bracket upper flange, a bracket lower flange and a bracket web plate; the H-type end is in butt joint with the flanges and theweb plate of the H-type bracket, connecting plates are arranged on the two sides of the flanges and the web plate and firmly connected through bolts, and then the box type beam and column connecting assembly type node is formed. Accordingly, the manufacturing cost is greatly lowered, on-site construction is more convenient, the labor intensity is lowered, box type beam node complete assembly connection is achieved, the box
