The invention discloses a frame structure of a container for transportation. The frame structure comprises four vertical column rods arranged symmetrically. L-shaped assembling grooves are formed in the upper end faces and the lower end faces of the vertical column rods; top frames are arranged in the positions, between the assembling grooves, of the upper end faces of the vertical column rods,; bottom frames are arranged in the positions, between the assembling grooves of the lower end faces of the vertical column rods; wall plates are arranged between the front end faces and the rear end faces of the top frames and the bottom frames; two or more frame-connecting strips are longitudinally arranged inside the top frames; mounting pieces are arranged below the frame-connecting strips; mounting grooves matched with the frame-connecting strips are formed in the tops of the mounting pieces; the depths of the mounting grooves are larger than the heights of the frame-connecting strips; and a top cover is arranged on the top frames. The frame structure has enough strength, hoisting is convenient, meanwhile, the overall structure of the device can be detached, a vulnerable part is convenient to replace, replacing is rapid, and logistics transportation is not affected.
