The utility model relates to an extensible steel structure connecting node, which is a sealed body composed by an extensible steel corrugated pipe and an oil baffle plate. The steel corrugated pipe comprises a plurality of corrugated sections and two connector sections, wherein the corrugated sections are formed by splicing a plurality of dish-shaped node pieces, the centers of the plurality of dish-shaped node pieces are on the same horizontal line, and two connector sections are arranged on two sides of the corrugated sections. The ratio between the radius of each dish-shaped node piece and that of the connector section is 4:1, the radius of each dish-shaped node piece and the thickness of the dish-shaped node piece is 4:1, and the oil baffle plate is arranged at outlet positions of the two connector sections in a blocking mode. By means of the extensible steel structure connecting node, traditional rigid nodes with small deformation adopt the flexible node form of the sealing body formed by the extensible
