Cable-stayed bridge girder cast-in-place and hanging basket assembly shared support system

The utility model provides a common support system for cast-in-place of a main beam of a cable-stayed bridge and assembly of a hanging basket. The common support system comprises a bearing platform, a cable bent tower limb, a plurality of first vertical rods, a plurality of second vertical rods, a plurality of connecting cross rods, a front fulcrum cable-stayed hanging basket, a bearing beam and a distribution beam. A mounting face is formed on the top face of the bearing platform, and a first embedded part is embedded in the side, facing the mounting face, of the bearing platform. The multiple first vertical rods and the multiple second vertical rods are borne by the bearing platform to be fixed, the multiple connecting transverse rods are connected with the multiple first vertical rods, the multiple second vertical rods and the cable bent tower limbs at the same time, and therefore the strength of the support structure is improved. The support structure bears the front fulcrum guy cable hanging basket, the
