Construction method for giant inclined truss structure of high-rise building

The invention relates to a construction method for a giant inclined truss structure of a high-rise building, and belongs to the technical field of building steel structure construction. The construction method comprises the following operating steps: firstly performing construction and installation on a main steel structure, and then performing positioning construction on an inclined truss base atthe side edge of the main steel structure; putting up a plurality of temporary supporting columns, playing a role of temporarily supporting the inclined truss structure, between the inclined truss base and the main steel structure; performing installation and connection operations of a lower chord, an upper chord and frame beams at the upper end of the inclined truss base until the inclined trussbase draws close to and is fixed to the upper part of the main steel structure; and after installation of the inclined truss structure is completed, performing integral one-time removal of temporarysupporting beams and the te
