Self-balancing supporting structure of large overhanging type building

The invention relates to a self-balancing supporting structure of a large overhanging type building, which relates to the technical field of overhanging type buildings and aims to solve the technical problem that a large overhanging structure is controlled to horizontally and vertically deform under the condition of gravity, and meanwhile, inclined post deformation and internal force can be reduced and floor cracking caused by horizontal pull can be avoided. The overhanging type building comprises a horizontal floor, and the invention is characterized in that the supporting structure comprises a V-shaped member and a plurality of prestressed pull rods; the V-shaped member comprises two inclined posts and an upward V-shaped opening, and the bottom ends of the two inclined posts fall to theground and are mutually bonded; both ends of each prestressed pull rod are respectively bonded with the two inclined posts; and the horizontal floor of the overhanging type building is supported on the V-shaped member. The self-balancing supporting structure can avoid or reduce the horizontal influence of an overhanging part on the integrated structure, effectively control and reduce the horizontal and vertical displacement of the inclined posts, reduce the post bottom bending moment and the shearing force of the inclined posts and avoid the floor cracking caused by the horizontal pull.
