Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0043] The utility model provides a fully prefabricated concrete modular building structure system, comprising a plurality of concrete modules 1. After the concrete modules 1 are prefabricated in a factory, they are hoisted at a construction site. The plurality of concrete modules 1 are stacked layer by layer to form a concrete modular building structure system that can be quickly installed at the construction site, thereby improving the construction speed of the building structure.

[0044] The concrete module 1 includes a hollow shear wall blade 11, a partition wall 12, a top plate 13 and a bottom plate 14. The shear wall blade 11 and the partition wall 12 are fixedly connected to form four sides of the concrete module 1.

The top plate 13 is fixed at the top of the shear wall blade 11 and the partition wall 12, serving as the top surface of the concrete module 1. The shear wall blade 11, the partition wall 12, the top plate 13 and the bottom plate 14 form a unit concrete module 1 that can be prefabricated in a factory.

[0045] The shear wall blade 11 is arranged at the corner of the concrete module 1, and the horizontal cross section is L-shaped or T-shaped, which can be selected according to the actual position of the shear wall blade 11. The shear wall blade 11 includes a first blade 111 and a second blade 112 arranged oppositely, and the first blade 111 and the second blade 112 are both provided with a uniformly arranged first steel frame 113. There are also a number of first tie bars 114 between the first steel skeleton 113 of the first blade plate 111 and the second blade plate 112. The first tie bars 114 are evenly distributed between the first blade plate 111 and the second blade plate 112. The first tie bars 114 are arranged along the horizontal direction, and the two ends of the first tie bars 114 are respectively fixedly connected to the first steel skeleton 113 in the first blade plate 111 and the second blade plate 112, so that a first cavity 115 for pouring concrete is formed between the first blade plate 111 and the second blade plate 112, so that the shear wall blade 11 after pouring concrete can achieve the structural strength of cast-in-place components on the basis of the advantages of fast installation speed and convenient construction of prefabricated components.

[0046] Preferably, the blades of this embodiment are cast with C60 concrete. The first steel skeleton 113 includes at least one layer of bidirectional steel bars, which are steel bars arranged in the horizontal direction and the vertical direction.

[0047] The concrete module 1 also includes a beam shell 15, which is arranged on the top of the partition wall 12. The beam shell 15 includes a first shell plate 151 and a second shell plate 152 that are arranged opposite to each other, and a beam shell waterproof layer 157 fixed to the bottom ends of the first shell plate 151 and the second shell plate 152. The two ends of the beam shell waterproof layer 157 are respectively fixedly connected to the first shell plate 151 and the second shell plate 152. The first shell plate 151 and the second shell plate 152 serve as two side surfaces of the beam shell 15, and the beam shell waterproof layer 157 serves as the bottom surface of the beam shell 15, so that a second cavity 153 for pouring concrete is formed between the first shell plate 151 and the second shell plate 152.

[0048] The first shell plate 151 and the second shell plate 152 are both provided with a second steel bar skeleton 154 and a second tie bar 155. The second steel bar skeleton 151 of this embodiment adopts a single-layer bidirectional steel bar, and the second tie bar 155 is arranged along the vertical direction, and both ends extend out of the first shell plate 151 and the second shell plate 152. The upper end of the second tie bar 155 is bent after binding, and the lower end of the second tie bar 155 is inserted into the partition wall 12. A steel cage 156 is also provided between the adjacent first shell plates 151 and the second shell plates 152, and the steel cage 156 is used to enhance the overall structural strength of the beam shell 15 after pouring concrete.

[0049] Preferably, the beam shell waterproof layer 157 of this embodiment is made of extruded board, and the moisture-proof and heat-insulating performance of the concrete module 1 is improved by arranging the beam shell waterproof layer 157 at the bottom of the beam shell 15 .

[0050] The height of the shear wall blade 11 is higher than the height of the partition wall 12. When the beam shell 15 is arranged at the top of the partition wall 12 between the two shear wall blades 11, the two ends of the beam shell 15 are respectively fixedly connected to the shear wall blades 11 at the two ends of the partition wall 12, and the second cavity 153 of the beam shell 15 is connected to the first cavity 115 of the shear wall blade 11. By arranging the beam shell 15 at the top of the partition wall 12, and the cavity inside the beam shell 15 is connected to the shear wall blade 11, the beam shell 15 and the shear wall blade 11 are poured with concrete to form a whole, thereby improving the connection strength between the shear wall blade 11, the partition wall 12 and the beam shell 15, and on the basis of having the advantages of fast installation speed of the prefabricated module, it can also have the structural strength of the cast-in-place structure.

The end of the third steel frame 131 extends to the top plate 13 as reserved steel bars for the top plate 13. The reserved steel bars are anchored to the second steel frame 151 of the beam shell 15.

[0053] The top plate 13 does not completely cover the top surface of the concrete module 1 during the prefabrication stage in the factory, that is, a cast-in-place section 132 is provided around the outer edge of the top plate 13. After the concrete module 1 is installed, the cast-in-place section 132 is cast in-place on the entire floor slab as a whole, so that the top plate 13 and the beam shell 15 can form a whole, thereby improving the connection strength of the module structure.

[0054] The steel cage 156 is also provided with lap ribs 134 at the bottom of the plate to enhance the structural connection strength between the top plate 13 and the beam shell 15 .

The vertical connection dowel bar 116 and the transverse additional rib 117 are tied before the concrete module 1 of the lower layer is poured.

[0058] The first blade 111 is located on the outside of the second blade 112. A waterproof sealing structure 16 is also provided at the connection between the first blade 111 located on the upper layer and the first blade 111 located on the lower layer. The waterproof sealing structure 16 includes a seat slurry, a polyethylene rod and a sealant arranged in sequence from the inside to the outside to enhance the waterproof sealing performance of the connection of the concrete module 1.

[0059] The partition wall 12 is also provided with door and window openings, which can be selected according to actual needs.

[0060] The utility model provides a fully prefabricated shear wall concrete modular building structure system, which forms a prefabricated concrete module 1 by combining a shear wall blade 11, a partition wall 12, a top plate 13 and a bottom plate 14. The shear wall blade 11 and the beam shell 15 have cavities for pouring concrete inside, which makes the overall weight of the concrete module 1 lighter and facilitates the rapid installation of the concrete module 1; at the same time, the internal cavities of the shear wall blade 11 and the beam shell 15 can be directly poured at the construction site without re-setting the formwork. The shear wall blade 11 and the beam shell 15 are permanent formworks for subsequent construction and pouring concrete, so that the concrete module 1 can achieve various performance indicators of the cast-in-place structure on the basis of the advantages of fast and convenient installation of prefabricated components, and can be used in high-intensity areas and non-high-intensity areas but buildings that require key defense, and are suitable for dormitories, affordable housing, renovation of old communities, urban renewal and other projects.
