The invention discloses an adjustable hanger system, which comprises a framework connected with a steel platform system and a steel jump plate fixed on the framework. The framework has a three-dimensional pane structure consisting of an inner hanger sheet, an outer hanger sheet and an inner and outer sheet connecting rod connected between the inner hanger sheet and the outer hanger sheet; both the inner hanger sheet and the outer hanger sheet comprise a suspender, a horizontal cross rod and a shaped joint tube at a node, which are arranged at intervals; and screw holes are uniformly distributed on the shaped joint tube, and the shaped joint tube is welded by a transverse tube joint, a longitudinal tube joint and a vertical tube joint, wherein the vertical tube joint is detachably connected with the inner and outer sheets through bolts, the transverse tube joint is detachably connected with the horizontal cross rod through bolts, and the longitudinal tube joint is detachably connected with the inner and outer sheet connecting rod through bolts. The hanger system can be widely applied to mounting construction of a high-rise concrete core tube structure of formwork creeping or lifting system construction, a steel structure and the like. The hanger system can meet the requirements of different buildings, realizes integral standardized operation, liberates a large amount of labor force, reduces the cost, and improves the safety of a hanger.
