The invention relates to the technical field of steel box girder hoisting, in particular to a segmental hoisting construction method and device for a steel box girder, according to the technical scheme, the segmental hoisting construction device comprises a base and a hoisting assembly, and the base is provided with a bottom frame, a guide rail and a protective frame; the lifting assembly comprises a bracket, a driving motor, a winding roller and a lifting hook. The construction method comprises the following steps: 1) a preparation stage: assembling the device, adjusting the distance between the underframes, and checking the hoisting assembly; (2) checking before hoisting, and confirming that an electrical system, a transmission system and a safety device are normal; 3) hoisting operation: starting a motor to control the lifting hook to lift; (4) moving adjustment is conducted, and the segments are moved to the installation positions; (5) mounting and fixing: accurately butting and fixing the sections; and (6) checking and accepting to ensure the mounting quality. Through the design of modularization, automation, motorization, safety guarantee, fine adjustment and accurate positioning, the problem that in the prior art, due to different sizes and shapes of steel box girders, a hoisting mechanism needs to be customized or adjusted is effectively solved, and the preparation time and cost before construction are reduced.
