Tower beam temporary consolidation supporting structure easy and quick to unload and manufacturing and construction process

The invention belongs to the technical field of bridge construction, relates to a tower beam temporary consolidation supporting structure easy to unload quickly and a manufacturing and construction process, and relates to tower beam temporary anchoring measures arranged for resisting unbalanced loads (horizontal force, vertical force and bending moment) during cantilever construction of an upper structure system of a floating or semi-floating cable-stayed bridge. The tower beam temporary consolidation supporting system steel main accessory is composed of a tower beam temporary consolidation supporting system steel main accessory body (an I-shaped beam with stiffening ribs), high-strength bolts, longitudinal bridge direction finish rolling threaded steel bars, vertical finish rolling threaded steel bars, anchoring steel plates and angle steel, and the structural form of the tower beam temporary consolidation supporting system steel main accessory body is an I-shaped steel beam with stiffening ribs.
