[0041] Embodiment 1

[0042] Reference Figures 1 to 4 The present invention provides a multi-story fully prefabricated concrete modular building structure, including a module unit 1, a vertical connection unit 2 and a horizontal connection unit. Several module units 1 are arranged in sequence in the horizontal direction to form a module combination layer, and several module combination layers are arranged in sequence in the vertical direction to form a building structure. Two adjacent module units 1 in the same module combination layer are connected by a horizontal connection unit, and two module units 1 in adjacent module combination layers located in the vertical direction are connected by a vertical connection unit 2.

[0043] The module unit 1 is a three-dimensional hexahedral structure. The module unit 1 is systematically and finely prefabricated in an assembly factory. During the prefabrication process, the overall production quality of the module can be ensured. The internal decoration of the module unit 1 can also be formed in one piece. At the same time, a three-dimensional forward deepening design can be adopted to ensure that the reserved embedded points are correct. At the subsequent construction site, only the connection of pipelines between the hexahedral structural components is required.

[0044] Then all the module units 1 are transported to the construction site, where they are hoisted and assembled on site. The adjacent module units 1 in the horizontal and vertical directions are connected through the horizontal connection units and the vertical connection units 2 respectively, and then combined with related work such as pipeline connection, the overall construction of the building structure can be completed, thereby effectively reducing the amount of wet work on the construction site, improving construction efficiency, and saving manpower and costs while ensuring quality.

[0045] The module unit 1 includes surrounding walls, a top plate 11 and a bottom plate 12. In the process of manufacturing and constructing each module unit 1, it is preferred to first connect the binding steel bars of the surrounding walls with the binding steel bars of the top plate 11, and form a pentahedron after concrete pouring and curing. Then, the obtained pentahedron is connected with the binding steel bars of the bottom plate 12, and the bottom plate is poured and cured to form a hexahedron.

[0046] The surrounding walls preferably include shear walls 13 and lightweight partition walls 14. Each module unit 1 can be individually designed for the distribution of the shear walls 13 and lightweight partition walls 14 according to actual use requirements to meet different design requirements;

[0047] The shear wall 13 is preferably composed of a wall limb, a wall body and an exposed C-shaped hole. The wall limb is preferably formed by a hole-forming process by means of an internal square corrugated tube to form a cavity 131. The cavity 131 can be used for the vertical connection unit 2 to extend into, thereby forming a vertical connection between two adjacent module units 1. The wall body is preferably formed by a combination structure of ordinary concrete and a weight-reducing plate, and the exposed C-shaped hole is preferably formed by a customized template.

[0048] The lightweight partition wall 14 is preferably made of fine stone concrete, and if necessary, a beam formwork is reserved at the top to facilitate the horizontal connection between two adjacent module units 1. After the two adjacent module units 1 are assembled, there will be two lightweight partition walls 14 arranged adjacent to each other. In this state, an air interlayer is arranged between the two lightweight partition walls 14 to improve the sound insulation effect.

[0049] The vertical connection unit 2 is mainly used for connecting the shear walls 13 . The vertical connection unit 2 preferably includes vertical connection steel bars, which can extend into the corresponding cavities 131 on two adjacent module units 1 in the vertical direction to form a lap connection between the two adjacent module units 1 .

[0050] The horizontal connection unit includes horizontal connection steel bars, which include negative bending moment bars 31 corresponding to the upper iron and structural lap joint bars 32 corresponding to the lower iron. At the connection support between two adjacent module units 1, the upper iron is preferably provided with negative bending moment bars 31, and preferably extends into the floor slab 900mm. The lower iron is preferably provided with structural lap joint bars 32 according to the specification requirements, and the lap length is preferably 100mm, so as to ensure that the horizontal connection of the left and right module units 1 meets the relevant specifications for assembly;

[0051] After the reinforcement is overlapped, concrete is poured and cured, and then a cast-in-place layer 41 is arranged on the top of the module units 1 on the same layer. The module units 1 on the same layer are further connected through the cast-in-place layer 41, and then a leveling layer 42 is arranged on the top of the cast-in-place layer 41 to achieve leveling, which is beneficial to the assembly and construction of the module combination layer on the upper layer.

[0052] The multi-story fully precast concrete modular building structure also includes an edge member connection unit 5, which is used to connect the edge members formed by the shear walls 13 corresponding to two adjacent module units 1. In this embodiment, the edge member connection unit 5 is preferably a steel cage that matches the edge member template. The steel cage is transported to the corresponding position by an external tool, and then the steel cage is overlapped with the binding steel bars reserved on the module unit 1. Synchronous pouring is achieved during the horizontal and vertical connections of the module units 1, saving construction period and improving construction efficiency.
