The invention relates to a ship body structure for a demountable large-sized A-shaped frame. A pair of thickened deck regions (1,2) are arranged on a deck for fixing an A-shaped frame, and fixed to a surrounding deck in a welding manner; the thickened deck regions are used as a base of the A-shaped frame, and parallel to the wood deck; stringers (3) and transverse beams (4) are fixedly arranged at the lower parts of the thickened deck regions, and welded under the deck; two ends of each of the stringers (3) and two ends of each of the transverse beams (4) are fixed to a ship body in a welded manner; the stringers (3) are arranged in the longitudinal direction of the ship body, and the transverse beams (4) are arranged in the transverse direction of the ship body. Through the adoption of the ship body structure, a load is dispersed to the ship body structure, and the stress is even; a reinforced structure is convenient to optimize by adopting a finite element method, so that the safety of a ship carrying the large-sized A-shaped frame is improved; the weight of the reinforced structure of the ship carrying the large-sized A-shaped frame is reduced; the utilization rate of a compartment is increased, so that the fixing manner of the large-sized A-shaped frame on the ship is simple and convenient, and the large-sized A-shaped frame is flexible to mount; compared with a manner of adding compartment walls or stand columns, the manner adopted by the ship body structure disclosed by the invention has the advantage that the weight of the ship body structure is reduced.
