The invention discloses an apparatus and a method for batch hoisting main reinforcement of a high concrete structure. The apparatus for batch hoisting the main reinforcement of the high concrete structure comprises a main framework, a hoisting appliance and a reinforcing steel bar positioning frame, wherein the middle part of the main framework is provided with two hanging table board, the inner side edges of the two hanging table boards are opposite to each other, the hanging table board is provided with a hanging table ear plate, the hanging table ear plate is hinged with the main framework,the hoisting appliance comprises hoisting arms, two groups of the hoisting arms are provided and respectively used for driving the two hanging table boards to rotate, so that the inner side edges ofthe two hanging table boards approach each other or leave each other, the reinforcing steel bar positioning frame is positioned on a to-be-installed position of a reinforcing steel bar and comprises alimiting plate, the front side and the rear side of the limiting plate are respectively provided with a positioning plate and a positioning frame, and a positioning groove is formed between the positioning plates. The reinforcing steel bar group can be clamped and released by virtue of the weight of the main framework and the hanging table plate, so that the problems of difficulty in positioningand low efficacy in the reinforcing steel bar hoisting process can be solved, the hoisting method is simple, the use is flexible and effective, and the apparatus has the advantage of energy conservation and consumption reduction.
