[0067] In one embodiment, the concrete modular box 1 of the present invention is prefabricated in the factory. After the prefabrication is completed in batches, the concrete modular box 1 is transported to the site for installation. After the concrete modular box 1 is arranged in the installation position, concrete columns 71, concrete beams 72 and concrete slabs 73 are poured on site. The concrete columns 71, concrete beams 72 and concrete slabs 73 form a concrete structure F to fix the concrete modular box 1.

S3: Column reinforcement 51 is provided in the column slot 11; beam reinforcement 52 is provided in the beam slot 151; slab reinforcement is provided in the slab slot 152; S4: Concrete is poured into the column groove 11, the beam groove 151 and the slab groove 152 to form concrete columns 71, concrete beams 72 and concrete slabs 73; finally, the concrete columns 71, concrete beams 72 and concrete slabs 73 form a concrete structure F to fix the concrete modular box 1.
[0070] Following step S4, step S5 is included: repeating steps S1 to S4, ultimately assembling several of the concrete modular boxes 1, combined with concrete columns 71, concrete beams 72, and concrete slabs 73, into a multi-story building structure (e.g., a high-rise building structure: ten stories or more, with a total building height greater than or equal to 24m). Preferably, when the building structure (i.e., the "concrete modular building structure") has at least two stories, the post-cast concrete columns 71, which play a major load-bearing role, maintain vertical continuity between upper and lower floors to ensure good "load-bearing and load-transfer" performance of the high-rise building structure.

The "beam-column-slab" frame system is distinguished. A2: Construct an information model (such as a BIM information model) of the modular concrete building structure and conduct overall calculation and analysis on the model; on this basis, conduct detailed design of the modular concrete box 1, and then clarify the specific functions, dimensions and structural details of each modular concrete box 1. A3: The factory designs and builds the overall mold of the concrete modular box 1 according to the shape of the concrete modular box 1. Reinforcing bars are set in the mold, and embedded electromechanical components and embedded parts are placed. Then, concrete is poured into the mold to form the preliminary structure of the concrete modular box 1. After that, the prefabricated infill wall 17 is filled to form the final concrete modular box 1.
[0073] After the concrete modular box 1 is fabricated, it is transported to the site for installation. During on-site installation, steps P0, S1, S2, S3, and S4 are performed.
[0074] Other aspects of the modular concrete building structure and construction method described in this invention can be found in the prior art and will not be repeated here.
[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
