Steel-encased concrete composite beam-steel pipe column connection joint

The invention discloses a steel-encased concrete composite beam-steel pipe column connection joint and a manufacturing method thereof. The joint comprises a steel pipe column, an upper through partition plate, a lower through partition plate, a lateral connection plate and the like; the upper through partition plate and the lower through partition plate are arranged on the steel pipe column in a transverse penetrating mode; hogging moment reinforcing steel bars are welded to the two ends of the end face of the upper through partition plate, the lower through partition plate and the lateral connection plate form a U-shaped device on the column side, and the U-shaped device can be made into a uniform cross-section or a variable cross-section form according to beam-column cross section size; a steel-encased girder is directly placed in the U-shaped device and connected with the U-shaped device through high-strength bolts. The steel-encased concrete composite beam-steel pipe column connection joint has the advantages that the welding work of the whole U-shaped device can be completed in a factory, a steel-encased girder bottom plate and a lateral plate are connected with the joint through high-strength bolts, the site welding work amount is greatly reduced, and construction and assembling are facilitated; the hogging moment reinforcing steel bars are directly welded to the upper through partition plate, the situation that steel pipe bearing capacity is weakened due to trepanning in the side wall of a steel pipe can be reduced, and force transfer is definite.
