Connecting cantilever structure system hub joint inclined column construction method

The invention discloses a connecting cantilever structure system hub joint inclined column construction method which comprises the steps of performing construction preparation, positioning and paying-off, installing a steel rib column and an H-shaped steel beam, connecting and binding column main reinforcement mechanical connection, mounting a column stirrup and a column template, pouring concrete inside a steel pipe, pouring concrete outside the steel pipe, erecting a beam (plate) bottom die, inserting and connecting beam main reinforcements, binding the beam stirrup, erecting a beam side die and a plate bottom die, binding plate steel bars, and pouring beam plate concrete. The construction method settles a relation between a steel column stud and a reinforcing bar outside a steel framework, so that frame column stirrups at the multidirectional intersection joints are treated when meeting steel ribs, it is ensured that after frame beam main reinforcements meet the steel rib columns, the frame beam main reinf
