The invention discloses a support-free balance-weight-free hanging basket hanging structure and a construction method thereof, and relates to the field of building structure construction. The support-free balance-weight-free hanging basket hanging structure is used for a roof structure with an inclined roof and the periphery with overhanging eaves, the system comprises two hanging systems arrangedin a spaced manner, each hanging system comprises an anchorage ring embedded in the roof wall, a steel casing pipe embedded between the parapet wall and an overhanging plate, an anti-friction hose inserted in the steel casing pipe, a lifting steel wire rope and a safety rope, and the lifting steel wire rope and the safety rope are inserted into the anti-friction hose in a penetrating manner. Theproblems that a hanging basket for hanging outer eave decoration needs to erect a frame or need a balance weight when the roof is the inclined roof and the periphery is provided with the outer overhanging eaves, the structure is complex, the construction is tedious, and the construction difficulty is large are solved.
