The invention relates to a module splicing structure. The module splicing structure comprises splicing modules, connecting parts, reinforcement accessories and functional accessories. Connecting structures of the splicing modules are provided with holes or grooves, the connecting parts are inserted into the holes or the grooves of the adjacent splicing modules, and the shapes of the cross sections of the wholes or the portions, inserted into the splicing modules, of the connecting parts are the same as the shapes of the cross sections of the holes or the grooves of the splicing modules. Due to connection of the connecting parts, the multiple splicing modules are spliced to form a structural whole or a structure. Under the effect of loads and external force acting on the spliced structure, the adjacent splicing modules and the connecting parts can generate torque to resist deformation and collapse of the spliced structure, and the spliced structure is kept stable. The module splicing structure is applied to the field of engineering construction, and is rapid and convenient to assemble, disassemble and maintain, the parts can be produced in an industrialized mode, universality is high, the requirements for the skills of assembling-disassembling operators are low, quality can be easily guaranteed, and the module splicing structure is convenient to transport and capable of being reused.
