The invention provides an installation method of a large-span steel truss overhanging special-shaped structure, which comprises a permanent support column, a temporary support column, a truss beam, a cantilever beam and a steel bar truss floor support plate, and the permanent support column and the temporary support column are used as support seats of the truss beam; the truss girder is of an arc-shaped steel truss structure, the two arc-shaped ends are connected with adjacent building components, and the cantilever beam is attached to the arc-shaped section of the steel truss and is in a double-layer radial shape. The steel bar truss floor support plate is laid on the cantilever beam, and concrete is poured in the later period to serve as a building structure floor; according to the method, components are partially and integrally spliced and then hoisted, and the frequency of aerial work of personnel is reduced as much as possible; the stress working conditions such as structure hoisting and temporary suppor
