Recoverable vertical bearing device of top-down area structure

The utility model discloses a recoverable vertical bearing device for a top-down area structure, which comprises a support pile, a plurality of groups of waist beams are arranged on the outer surface of one side of the support pile, and a connecting mechanism is arranged on the waist beams. According to the recoverable vertical bearing device for the top-down area structure, the number of pile foundations in the top-down area can be greatly reduced through the arranged large-span truss, so that the construction cost and period of the pile foundations in the top-down area are reduced, and the construction difficulty is reduced; compared with a conventional reverse construction method that a steel pipe column or a latticed column is adopted as a load-bearing component in the construction stage, the first-layer large-span truss in a reverse construction area is constructed in sequence, the paying-off construction can be accurately positioned, the problem of positioning deviation of the temporary latticed column
