The invention relates to the field of buildings, and discloses a flexible connecting device of an external prestressing steel strand reinforced bolt-sphere net rack, which comprises a U-shaped steel wire rope, two end parts of an opening part of the U-shaped steel wire rope are connected with flange plates through screw rods, and the upper parts of the flange plates are provided with lifting lugs; a connecting block is arranged in the middle of the closed section of the U-shaped steel wire rope, and a sealing plate is arranged on the lower portion of the connecting block. According to the flexible connecting device for reinforcing the bolt-sphere net rack through the external prestress steel strands, the bearing capacity of the bolt-sphere net rack can be effectively improved, and the deflection of the bolt-sphere net rack can be effectively reduced. By the adoption of the flexible connecting device for reinforcing the bolt-sphere net rack through the external prestress steel strands, the indoor clear height is basically not reduced; construction cost is low, period is short, and operation is simple.
