[0033] Example 1:

[0034] like Figures 1-14 In this invention, a basic modular assembly for prefabricated buildings includes a load-bearing plate 5, a first lightweight plate 6, and a second lightweight plate 7. The load-bearing plate 5 includes a first three-dimensional steel mesh 506 and a concrete layer covering the first three-dimensional steel mesh 506. The load-bearing plate 5 has multiple parallel and spaced first strip grooves 504 and first strip protrusions 505 on both sides. The load-bearing plate 5 also has multiple second threaded sleeves 507 on both sides, which are connected to the first three-dimensional steel mesh 506. The first lightweight plate 6 and the second lightweight plate 7 are assembled to form a thin wall panel structure 3. The first lightweight plate 6 and the second lightweight plate 7 are respectively assembled with the two sides of the load-bearing plate 5 to form a thick wall panel structure 2.

[0035] The first three-dimensional steel mesh frame 506 is a mesh structure made of steel bars and serves as the load-bearing skeleton structure of the load-bearing plate 5.

[0036] In the preferred embodiment, the load-bearing plate 5 is provided with a through first mounting hole 502, and a first threaded sleeve 501 is embedded in the side end of the load-bearing plate 5. The first threaded sleeve 501 is connected to the first three-dimensional steel mesh frame 506.

[0037] In a preferred embodiment, a first connecting bolt 503 is also provided. The first connecting bolt 503 passes through the first mounting hole 502 and is threadedly connected to the first threaded sleeve 501 of the adjacent load-bearing plate 5 so that the two load-bearing plates 5 are arranged vertically and connected to form a corner structure 4.

[0038] In the preferred embodiment, the two corner structures 4 are connected end to end to form a ring structure to form a load-bearing plate 5.

[0039] Each first threaded sleeve 501 is welded to the first three-dimensional steel mesh frame 506 before the load-bearing plate 5 is cast and formed. When concrete is poured on the first three-dimensional steel mesh frame 506, the first threaded sleeve 501 is sealed with a plug to prevent concrete from entering.

[0040] In the preferred embodiment, each load-bearing plate 5 of the hollow column structure 1 has a threaded insert 508 with threaded connection in the second threaded sleeve 507 on the inner side of each load-bearing plate 5, and a second three-dimensional steel mesh 509 is provided inside the ring structure formed by the load-bearing plates 5, and each threaded insert 508 is inserted into the hollow gap of the second three-dimensional steel mesh 509.

[0041] Each load-bearing plate 5 has a row of first mounting holes 502 on both sides. One side is used to connect the side end of the adjacent load-bearing plate 5, while the other side's first mounting hole 502 is not used and can be used to inject concrete grout into the internal cavity of the annular structure. The threaded rod 508 is inserted horizontally into the second three-dimensional steel mesh 509. After the concrete solidifies, the four load-bearing plates 5 are fixed together with the central pre-cast column, which strengthens the load-bearing structure.

[0042] In the preferred embodiment, the first strip groove 504 and the first strip protrusion 505 on both sides of the load-bearing plate 5 in the thick wall panel structure 2 are respectively inserted into the second strip groove 601 and the second strip protrusion 602, as well as the third strip groove 701 and the third strip protrusion 702. A second connecting bolt 605 and a third connecting bolt 705 are also provided. The second connecting bolt 605 passes through the second mounting hole 603 and is threadedly connected to the second threaded sleeve 507 to connect the first lightweight plate 6 and the load-bearing plate 5. The third connecting bolt 705 passes through the third mounting hole 703 and is threadedly connected to the second threaded sleeve 507 to connect the second lightweight plate 7 and the load-bearing plate 5.

[0043] In a preferred embodiment, multiple parallel and spaced first vertical gaps 607 are provided between the load-bearing plate 5 and the first lightweight plate 6, and between the load-bearing plate 5 and the second lightweight plate 7. The first lightweight plate 6 is provided with a first connecting groove 604, and the second lightweight plate 7 is provided with a second connecting groove 704. The first connecting groove 604 and the second connecting groove 704 connect adjacent first vertical gaps 607.

[0044] A mesh channel is formed at the interface of the first lightweight plate 6, the load-bearing plate 5, and the second lightweight plate 7. After the load-bearing plate 5, the first lightweight plate 6, and the second lightweight plate 7 are connected by bolts, concrete can be poured into the mesh channel from the end to fill the gaps and fix the first lightweight plate 6, the load-bearing plate 5, and the second lightweight plate 7 into one unit.

[0045] In the preferred embodiment, the second strip groove 601, the second strip protrusion 602, and the third strip groove 701 and the third strip protrusion 702 in the thin wall panel structure 3 are interlocked with each other, and a third connecting bolt 705 is also provided. The third connecting bolt 705 passes through the third mounting hole 703 and is threadedly connected to the third threaded sleeve 606 to connect the first lightweight plate 6 and the second lightweight plate 7.

[0046] In a preferred embodiment, the interface between the first lightweight plate 6 and the second lightweight plate 7 is provided with a plurality of parallel and spaced second vertical gaps 706, the first lightweight plate 6 is provided with a first connecting groove 604, the second lightweight plate 7 is provided with a second connecting groove 704, and the first connecting groove 604 and the second connecting groove 704 connect adjacent second vertical gaps 706.

[0047] The first strip groove 504, the first strip protrusion 505, the second strip groove 601, the second strip protrusion 602, the third strip groove 701, and the third strip protrusion 702 are mainly interlocked to prevent the plate structure from sliding laterally. The height of the protrusion structure is less than the depth of the groove structure, thus forming a strip cavity channel. They are interconnected by transverse connecting grooves to form a network channel for grouting and connecting the contact surface.

[0048] In a preferred embodiment, the load-bearing plate 5 has a fourth strip-shaped groove 12 on both sides. A fourth threaded sleeve 8 connected to the first three-dimensional steel mesh 506 is provided at the fourth strip-shaped groove 12. The fourth threaded sleeve 8 has a first inner protruding locking part 803 and an inner thread part 805. There is a gap between the first inner protruding locking part 803 and the inner thread part 805. An insertion device 9 is also provided. One end of the insertion device 9 has an outer thread part 902. The other end of the insertion device 9 has a plurality of strip-shaped petals 901 arranged circumferentially. The strip-shaped petals 901 are elastic. There is a gap groove between each strip-shaped petal 901. The end of each strip-shaped petal 901 has an outer protruding locking part 903. The outer thread part 902 is threadedly connected to the inner thread part 805. The end of the insertion device 9 with the strip-shaped petals 901 is inserted into the fourth threaded sleeve 8 of the adjacent load-bearing plate 5 so that the first inner protruding locking part 803 locks the outer protruding locking part 903.

[0049] A second inner protruding locking part 804 is also provided on the side of the first inner protruding locking part 803 near the inner thread part 805. On the side of the outer protruding locking part 903 of each strip petal 901 near the outer thread part 902, a plurality of elastic bending springs 10 are also provided along the circumference of the insert device 9. Each bending spring 10 is staggered along the length direction of the strip petal 901. The bending spring 10 includes a welding end 1001 and a raised part 1002. The welding end 1001 is welded to the outer wall of the strip petal 901, and the raised end of the raised part 1002 is stuck between the first inner protruding locking part 803 and the second inner protruding locking part 804.

[0050] When multiple load-bearing plates 5 or thick wall panel structures 2 form a wall, first screw one end of the external threaded portion 902 of the insert device 9 into the fourth threaded sleeve 8 and lock it with the insert locking nut 11. Then, move the next load-bearing plate 5 laterally until its end is aligned with the previous load-bearing plate 5. At this time, one end of the strip-shaped petal 901 of the insert device 9 will be inserted into the fourth threaded sleeve 8 of the adjacent load-bearing plate 5. The insert device 9 has a cavity in the center. Since the strip-shaped petal 901 has a certain deformation recovery ability, when the outward convex locking portion 903 is released to the first inward convex locking portion 803, it is gradually squeezed inward and deformed until the outward convex locking portion 903 passes over the first inward convex locking portion 803 and reaches the other side of the first inward convex locking portion 803. Since the bending springs 10 are staggered, there will always be a raised portion 1002 of a bending spring 10 in a relatively concave position between the first inward convex locking portion 803 and the second inward convex locking portion 804, making it difficult for the strip-shaped petal 901 to easily retract in the opposite direction. Because there is a gap groove between adjacent strip petals 901, it can pass into the cavity. The fourth strip groove 12 is a trapezoidal groove structure. Therefore, when the two load-bearing plates 5 are arranged side by side to form a wall, grout can be injected into the channel formed by the two fourth strip grooves 12. The concrete grout enters the cavity of the insert device 9 through the gap groove, gradually filling the gap between the outer protruding part 903 and the first inner protruding part 803 and the gap below the raised part 1002. The strip petals 901 and the bending spring 10 can no longer deform. After the concrete solidifies, the insert device 9 connects the two load-bearing plates 5 into one.

[0051] The fourth threaded sleeve 8 has a flange 801 at one end of its outer wall that extends deeper into the load-bearing plate 5. Multiple outward-extending posts 802 are located circumferentially on the outer wall of the fourth threaded sleeve 8. Other threaded sleeve structures can be designed identically to the fourth threaded sleeve 8, and all can be quickly connected between adjacent modules via the insertion sleeve device 9. The fourth threaded sleeve 8 can be pre-embedded in the first lightweight plate 6 and the second lightweight plate 7 to facilitate connection between adjacent thin wall panel structures 3. Since each threaded sleeve is located within a groove, multiple load-bearing plates 5 can also be connected and thickened in the thickness direction using this method.

[0052] Example 2:

[0053] like Figure 15A prefabricated building based on basic modules includes multiple column assemblies, multiple wall panel assemblies arranged side by side between adjacent column assemblies, a beam structure above the column assemblies and wall panel assemblies, and a floor slab structure on the beam structure.

[0054] The column assembly, wall panel assembly, and floor slab structure are all prefabricated, while the beam structure is flexibly prefabricated according to the building structure.

[0055] The floor slab structure consists of multiple load-bearing slabs arranged side by side, with a cast-in-place layer above the load-bearing slabs.
