[0038] Example 1

[0039] This application provides a prefabricated wall beam and slab modular assembly system, such as... Figure 1As shown, it includes: a first module 1, which is a hollow cuboid structure, including a first top plate 101 and four first walls surrounding the first top plate 101, the four first walls being divided into a pair of first connecting walls 102 arranged opposite each other along a first direction and a pair of second connecting walls 103 arranged opposite each other along a second direction; a second module 2, which is a hollow cuboid structure, including a second top plate 201 and a pair of second walls 202 arranged opposite to the second top plate 201; and a third module 3, which includes a first... The three roof slabs 301 and a pair of beam structures 302 opposite to the third roof slab 301; and the fourth template 4; wherein, the side of the second module 2 adjacent to the second wall 202 is used to connect with the first connecting wall 102, the beam structure 302 is used to connect with the second connecting wall 103, and the first roof slab 101, the second roof slab 201, the third roof slab 301 and the fourth template 4 can overlap each other so that the first module 1, the second module 2, the second module 2 and the fourth template 4 can be spliced ​​into the target shape.

[0040] The first module 1, second module 2, third module 3, and fourth template 4 can be prefabricated in the factory in advance. The first module 1 is a hollow cuboid structure, including a first top plate 101 and four first walls. The four first walls are divided into a pair of first connecting walls 102 and a pair of second connecting walls 103 along a first direction and a second direction, and the first direction and the second direction are perpendicular to each other. The second module 2 is also a hollow cuboid structure, with a second top plate 201 and a pair of second walls 202. The pair of second walls 202 are arranged opposite each other on both sides of the second top plate 201 to form an N-shaped structure. The third module 3 includes a third top plate 301 and a pair of beam structures 302, which are arranged opposite each other on both sides of the third top plate 301. The fourth template 4 is also prefabricated according to the design specifications.

[0041] The side of the second module 2 adjacent to the second wall 202 can be connected to the first connecting wall 102 of the first module 1, that is, the side of the second module 2 without a wall can be connected to the first module 1, so that the first connecting wall serves as the wall of the second module 2. The beam structure 302 of the third module 3 can be connected to the second connecting wall 103 of the first module 1, and the second connecting wall 103 can serve as a support for the third module 3. The first top plate 101, the second top plate 201, the third top plate 301, and the fourth template 4 overlap each other, according to the target building design. By splicing multiple first modules 1, second modules 2, third modules 3, and fourth templates 4, a multi-story apartment or dormitory building can be formed. Each floor can be composed of multiple first modules 1 and second modules 2 as basic living units, and the third modules 3 and fourth templates 4 can be used to construct public areas such as corridors, ultimately presenting a multi-story residential building form.

[0042] By prefabricating each module in the factory, only quick docking and overlapping operations are required on-site, reducing on-site wet work and complex construction steps. Compared with traditional concrete modular box connection methods, there is no need for lengthy erection and dismantling of formwork supports, greatly accelerating the on-site assembly speed and significantly improving construction efficiency. The prefabricated wall beam and slab modular assembly system is not only suitable for highly standardized building types such as apartments and hotels, but also allows for adjustment of module size and configuration according to specific needs, demonstrating strong adaptability and flexibility.

[0043] In some embodiments, the first module 1 can be used to form a house structure; the first connecting wall 102 can serve as the wall of the second module 2 and form a house structure with the second wall 202; the third module 3 can form a corridor space with a pair of second connecting walls 103; and the fourth module 4 can form a corridor space with a pair of second walls 202.

[0044] Taking house construction as an example, the side of the second module 2 adjacent to the second wall 202 can be connected to the first connecting wall 102, and the second module 2 and the first module 1 can be securely connected using connectors. At this time, the first connecting wall 102 serves as the wall of the second module 2, and together with the second wall 202, it constitutes part of the wall structure of the house, forming room partitions or exterior wall structures, and improving the overall layout of the house.

[0045] The first module 1 can be configured as a pair, with the pair of first modules 1 facing each other and the second connecting walls 103 in the first module 1 facing each other. At the location where a corridor is needed, the beam structure 302 of the third module 3 is connected to the pair of second connecting walls 103, ensuring a secure connection through bolts or welding. The beam structure 302 and the second connecting walls 103 together support and form the roof structure of the corridor. Similarly, the second module 2 can be configured as a pair, with the pair of second modules 2 facing each other and the second walls 202 in the second module 2 facing each other. The fourth template 4 can be spliced ​​with the pair of second walls 202, and the pair of second walls 202 support the fourth template 4 to form the walls and roof of the corridor, thus completing the corridor space.

[0046] The first module 1 serves as the main space of the building. The combination of the second module 2 with the first connecting wall 102, and the cooperation of the third module 3 and the fourth module 4 with other modules, allows for flexible division of the interior space to meet diverse architectural functional needs. Whether it is a residential, office, or commercial building, different spatial layouts can be achieved through different module combinations. By prefabricating each module in the factory, only assembly and connection are needed on-site to form a stable building system, reducing the complexity and uncertainty of on-site construction.

[0047] In some embodiments, such as Figures 2 to 7 , Figures 10 to 16As shown, the first top plate 101 is rectangular, and each of its four sides is provided with a first lap groove 104. The first top plate 101 extends horizontally outwards with reinforcing bars. The second wall 202 extends vertically within the first lap groove 104, and the first lap groove 104 can connect with the second top plate 201 and / or the third top plate 301. The second top plate 201 is rectangular, and the two sides of the second top plate 201 that connect with the second wall 202 are provided with second lap grooves. The second top plate 201 extends horizontally to its periphery with reinforcing bars, and the second wall 202 extends vertically within the second lap groove 203 with reinforcing bars. The second lap groove 203 can be connected to the fourth formwork 4. The third top plate 301 is rectangular, and the two sides of the third top plate 301 that connect with the beam structure 302 are provided with third lap grooves 303. The third top plate 301 extends horizontally to its periphery with reinforcing bars, and the third lap grooves 303 can be connected to the fourth formwork 4.

[0048] The first top plate 101 is processed into a rectangle, and first lap grooves 104 are opened on the four sides. The first lap grooves 104 are set through the length of the side. The first top plate 101 has multiple steel bars inside, and the steel bars in the first top plate 101 extend outwards in the horizontal direction. The second wall 202 has multiple steel bars inside, and the second wall 202 extends outwards in the first lap grooves 104 in the vertical direction.

[0049] Similarly, the second top plate 201 of the second module 2 is processed into a rectangle, and the two sides connecting with the second wall 202 are provided with second lap grooves 203. The reinforcing bars in the second top plate 201 extend horizontally to the periphery, and the reinforcing bars in the second wall 202 extend vertically to the second lap grooves 203. The third top plate 301 of the third module 3 is also rectangular, and the two sides connecting with the beam structure 302 are provided with third lap grooves 303. The reinforcing bars in the third top plate 301 extend horizontally to the periphery.

[0050] The first lap groove 104 of the first module 1 provides space for the lap joint of the second top plate 201 and / or the third top plate 301; the second lap groove 203 of the second module 2 provides space for the lap joints on both sides of the fourth formwork 4; and the third lap groove 303 of the third module 3 provides space for the lap joints on the other two sides of the fourth formwork 4. The reinforcing bars of each module and formwork can interlock within the lap grooves and can be fixedly connected by grouting or other connection methods to complete the construction of the entire building structure.

[0051] By arranging transverse and longitudinal distribution bars in the lap grooves of the top plates of each module, and combining grouting and concrete pouring, the connection between modules is made tighter, eliminating concerns about cracking of the connection groove 204, and effectively enhancing the integrity and stability of the building structure.

[0052] The standardized lap joint and reinforcement design provides clear positioning and connection methods for on-site assembly of modules. Construction workers can quickly and accurately connect the modules, while reducing the complex procedures of traditional construction such as formwork erection and rebar tying. This simplifies the construction process and improves construction quality.

[0053] In some embodiments, such as Figure 8 and Figure 9 As shown, the fourth template 4 is a rectangular plate structure. A pair of opposite sides of the fourth template 4 are provided with a fourth lap groove 401. The fourth template 4 extends ribs horizontally to its periphery. The fourth lap groove 401 is used to connect with the third lap groove 303. The other two sides of the fourth template 4 are used to connect with the second lap groove 203.

[0054] The fourth template 4 is processed into a rectangular plate structure, with fourth lap grooves 401 opened on its two opposite sides, and reinforcement bars extending horizontally outwards from the fourth template 4. The side with the fourth lap groove 401 can be joined with the third lap groove 303 of the third module 3, so that the reinforcement bars of both interlock. Then, the other two sides of the fourth template 4 are joined with the second lap groove 203 of the second module 2, ensuring a tight fit between the modules. Finally, by pouring concrete, the reinforcement bars of each module and the concrete form a solid whole, completing the construction of the first-floor building structure.

[0055] The fourth formwork 4 precisely connects with the third lap groove 303 and the second lap groove 203 via the fourth lap groove 401, forming a crisscrossing steel reinforcement network in conjunction with the extended bars from each module. After concrete pouring, each module and the fourth formwork 4 are tightly integrated into a single unit. The steel reinforcement connections on the top slabs of each module and on the fourth formwork 4 can utilize U-shaped steel reinforcement laps to reduce the size of the lap grooves on the top slab.

[0056] In some embodiments, such as Figure 3 , Figure 10 and Figure 11 As shown, a plurality of transverse connecting ribs 105 are evenly distributed on the outer surface of the first connecting wall 102 along the height direction of the first connecting wall 102. The transverse connecting ribs 105 are arranged horizontally and are annular. The plurality of transverse connecting ribs 105 are arranged in two rows corresponding to the positions of a pair of second walls 202. The second wall 202 has connecting grooves 204 on both sides along the length direction. The connecting grooves 204 are provided with a plurality of annular lap ribs 205 and longitudinal control ribs 206. The longitudinal control ribs 206 are connected to the plurality of annular lap ribs 205. The longitudinal control ribs 206 are used to control the switching of the annular lap ribs 205 between the horizontal state and the inclined state. In the state where the first connecting wall 102 is docked with the second module 2, the plurality of transverse connecting ribs 105 can extend into the connecting grooves 204 and overlap with the plurality of annular lap ribs 205.

[0057] In the factory prefabrication workshop, the first module 1 and the second module 2 can be manufactured according to the design requirements. When manufacturing the first connecting wall 102 of the first module 1, multiple rows of horizontal connecting ribs 105 are evenly arranged along the height of the wall. Each horizontal connecting rib 105 is processed into a ring and fixed in the horizontal direction. The multiple horizontal connecting ribs 105 are arranged in two columns corresponding to the positions of a pair of second walls 202.

[0058] When constructing the second wall 202 of the second module 2, connecting grooves 204 are opened on both sides along its length. Multiple annular lap bars 205 and longitudinal control bars 206 are pre-installed within the connecting grooves 204. The longitudinal control bars 206 are connected and fixed to the annular lap bars 205, allowing the longitudinal control bars 206 to control the switching between horizontal and inclined states of the annular lap bars 205. The binding of the annular lap bars 205 and the longitudinal control bars 206 can be completed in the factory, eliminating the need for on-site arrangement, reducing on-site workload, and improving construction efficiency. Furthermore, during hoisting and transportation, the annular lap bars 205 can be concealed within the connecting grooves 204, eliminating concerns about deformation or damage.

[0059] First, the first module 1 is hoisted to the predetermined position and fixed. Then, the second module 2 is hoisted, aligning the connecting groove 204 of the second wall 202 with the transverse connecting bars 105 on the first connecting wall 102. Before docking, the longitudinal control bar 206 is operated to adjust the annular lap bar 205 to an inclined state, facilitating the insertion of the transverse connecting bars 105 into the connecting groove 204. After the first connecting wall 102 and the second module 2 are initially docked, the longitudinal control bar 206 is operated again to switch the annular lap bar 205 back to a horizontal state, allowing multiple transverse connecting bars 105 to overlap with multiple annular lap bars 205. After the overlap is completed, grouting or concrete pouring is used to form a whole between the reinforcing bars and the concrete, completing the connection between the first connecting wall 102 and the second module 2.

[0060] The lap joint design of the transverse connecting bar 105 and the annular lap bar 205, combined with the concrete pouring, forms a robust reinforced concrete connection node between the first module 1 and the second module 2. The longitudinal control bar 206 controls the switching of the annular lap bar 205's state, enabling easier and faster rebar connection during module assembly. This not only reduces the outward extension distance of the rebar in the first module 1, lowering the module fabrication difficulty, but also eliminates the need for complex on-site rebar tying and adjustment work, reducing on-site construction procedures, shortening construction time, improving on-site assembly efficiency, and accelerating the building construction progress.

[0061] In some embodiments, such as Figure 7 and Figure 12As shown, a first steel section 106 is provided on the outer surface of the second connecting wall 103 near the first top plate 101; a beam structure 302 is provided along the side of the third top plate 301, and the beam structure 302 is provided on the side surface of the third top plate 301 facing away from the third lap groove 303. A second steel section 304 is provided at both ends of the beam structure 302 along the length direction, and the second steel section 304 is fixedly connected to the first steel section 106.

[0062] When fabricating the first module 1, the first steel section 106 is installed on the outer surface of the second connecting wall 103 near the first top plate 101 by welding, bolting, or pre-embedding. When fabricating the third module 3, the beam structure 302 can be installed along the side of the third top plate 301 on the surface facing away from the third lap groove 303, and can also be fixed by welding or steel bar connection to ensure the stability of the beam structure 302. Subsequently, the second steel section 304 is installed at both ends of the beam structure 302 along its length, so that the second steel section 304 is tightly connected to the beam structure 302.

[0063] First, hoist the first module 1 to the designated position and fix it in place. Then, hoist the third module 3, aligning the second steel sections 304 at both ends of the beam structure 302 with the first steel sections 106 on the second connecting wall 103 of the first module 1. Securely fix the second steel sections 304 and the first steel sections 106 using bolts, welding, or high-strength grouting sleeves, thus achieving a reliable connection between the third module 3 and the first module 1.

[0064] The connection between the first steel section 106 and the second steel section 304 provides a high-strength connection node between the first module 1 and the third module 3. The steel sections themselves possess high strength and rigidity, effectively bearing various loads generated during the building's use. With the steel sections pre-installed on the prefabricated modules, only the connection of the steel sections needs to be performed on-site, greatly simplifying the construction process compared to the complex node treatment and rebar tying procedures in traditional construction.

[0065] In some embodiments, a pair of first longitudinal connecting bars 107 are provided on both sides of the first steel 106 on the second connecting wall 103; a pair of second longitudinal connecting bars 305 are provided on both sides of the second steel 304 on the beam structure 302, the length of the second longitudinal connecting bars 305 is greater than the length of the second steel 304, and the sum of the lengths of the pair of second longitudinal connecting bars 305 and the second steel 304 is less than the length of the side of the third top plate 301; the first longitudinal connecting bars 107 can be tied to the second longitudinal connecting bars 305.

[0066] When constructing the second connecting wall 103 of the first module 1, a pair of first longitudinal connecting ribs 107 are symmetrically embedded on both sides of the first steel section 106. The first longitudinal connecting ribs 107 can be U-shaped. When constructing the beam structure 302 of the third module 3, a pair of second longitudinal connecting ribs 305 are symmetrically arranged on both sides of the second steel section 304. The second longitudinal connecting ribs 305 can be U-shaped, ensuring that the length of the second longitudinal connecting ribs 305 is greater than that of the second steel section 304, and that the sum of the lengths of the pair of second longitudinal connecting ribs 305 and the second steel section 304 is less than the length of the side of the third top plate 301. At the same time, the second longitudinal connecting ribs 305 are firmly connected to the beam structure 302. By making the sum of the lengths of the pair of second longitudinal connecting ribs 305 and the second steel section 304 less than the length of the side of the third top plate 301, the side of the third top plate 301 can be more closely aligned with the side of the first top plate 101, thereby reducing the amount of on-site wet pouring.

[0067] First, hoist the first module 1 to the designated position and fix it in place. Then, hoist the third module 3, aligning the second steel section 304 on the beam structure 302 with the first steel section 106 on the second connecting wall 103 of the first module 1, while simultaneously aligning the second longitudinal connecting bar 305 with the first longitudinal connecting bar 107. Use wire or rebar tying tools to tie the first longitudinal connecting bar 107 and the second longitudinal connecting bar 305 together, ensuring a secure connection and even distribution of tying points.

[0068] The binding of the first longitudinal connecting bar 107 and the second longitudinal connecting bar 305, in conjunction with the steel section connection, forms a crisscrossing steel reinforcement network at the module connection. This connection method can effectively transfer tensile and shear forces, enhancing the collaborative working ability between the first module 1 and the third module 3. Temporary fixation of the third module 3 is achieved by welding the extended embedded steel section of the first module 1 to the third module 3, eliminating the need for additional supports. Concrete is then poured at the connection node to complete the connection. At this point, the U-shaped second longitudinal connecting bar 305 of the third module 3 and the extended U-shaped first longitudinal connecting bar 107 of the first module 1 form an lap relationship at the connection point, requiring only binding operations on-site. Compared to the extensive on-site processing of steel reinforcement and complex connection processes in traditional construction, this greatly simplifies the construction steps.

[0069] In some embodiments, the area enclosed by the four first walls is larger than the size of the first top plate 101. The first top plate 101 covers the top surface of the four first walls. The first overlap groove 104 is stepped, and the first overlap grooves 104 on the four sides of the first top plate 101 are connected. The area of ​​the pair of second walls 202 is larger than the size of the second top plate 201. The second overlap groove 203 is stepped, and the fourth template 4 can overlap the second wall 202. At least a portion of the beam structure 302 extends beyond the area of ​​the third top plate 301. The third overlap groove 303 is stepped, and the fourth template 4 can overlap the beam structure 302.

[0070] The area enclosed by the four first walls is larger than the size of the first top plate 101. The first top plate 101 is placed on the top surface of the four first walls, and stepped first overlapping grooves 104 are processed on the four sides of the first top plate 101, ensuring that the first overlapping grooves 104 on the four sides are interconnected.

[0071] The area of ​​the second wall 202 is larger than the size of the second top plate 201, and stepped second overlap grooves 203 are machined on the two sides where the second top plate 201 connects to the second wall 202. For the third module 3, at least a portion of the beam structure 302 extends beyond the area of ​​the third top plate 301, and stepped third overlap grooves 303 are machined on the two sides where the third top plate 301 connects to the beam structure 302. By making the wall size larger than the top plate and the beam structure 302 extend beyond the top plate, more overlap space can be formed during the module assembly process.

[0072] In some embodiments, concrete material is filled between the first lap groove 104 and the second top plate 201, between the first lap groove 104 and the third top plate 301, between the second lap groove 203 and the fourth template 4, and between the third lap groove 303 and the fourth lap groove 401.

[0073] At the construction site, the first module 1, the second module 2, the third module 3, and the fourth template 4 were hoisted and assembled sequentially according to the design plan. The second wall 202 of the second module 2 was connected to the first connecting wall 102 of the first module 1, aligning the second top plate 201 with the first overlapping groove 104 of the first top plate 101. The beam structure 302 of the third module 3 was connected to the second connecting wall 103 of the first module 1, with the third top plate 301 corresponding to the first overlapping groove 104. The fourth template 4 was then overlapped with the second overlapping groove 203 of the second module 2 and the third overlapping groove 303 of the third module 3. Each module was initially fixed by pre-embedded steel bars, structural steel, and other structures to ensure accurate module positioning and proper fit of the overlapping grooves.

[0074] By filling the joints between the modules with concrete, the individual modules are firmly bonded together as a whole. The concrete, together with the reinforcing bars and structural steel in the modules, forms a reinforced concrete structure, which effectively improves the load-bearing capacity and deformation resistance of the building structure.

[0075] In some embodiments, such as Figure 14 and Figure 16As shown, the first module 1 also includes a plurality of first diagonal reinforcing ribs, which extend from the first top plate 101 into the first wall; the second module 2 also includes a plurality of second diagonal reinforcing ribs 207, which extend from the second top plate 201 into the second wall 202 at the second lap groove 203 on the second top plate 201; the third module 3 also includes a plurality of third diagonal reinforcing ribs 306, which extend from the third top plate 301 into the beam structure 302.

[0076] At the connection between the first top plate 101 and the first wall, multiple first diagonal reinforcing ribs are installed, with one end of each rib firmly connected to the interior of the first top plate 101 and the other end connected to the interior of the first wall. When manufacturing the second module 2, at the location where the second top plate 201 has the second lap groove 203, multiple second diagonal reinforcing ribs 207 are fixed at one end inside the second top plate 201 and extend to the interior of the second wall 202. When manufacturing the third module 3, multiple third diagonal reinforcing ribs 306 are connected at one end to the third top plate 301 and extend to the interior of the beam structure 302.

[0077] The first diagonal reinforcing rib, the second diagonal reinforcing rib 207, and the third diagonal reinforcing rib 306 form diagonal support structures within their respective modules, effectively enhancing the stability of the modules themselves. The diagonal reinforcing ribs and the connection structure at the lap joint cooperate to better withstand tensile, shear, and bending moments between modules, making the module connections more robust and reliable, preventing cracking and loosening at the connection points, and improving the durability of the building structure.

[0078] The prefabricated wall beam and slab module assembly system of this application embodiment has a simple structure and is easy to connect, requiring only steel bar binding. It has fewer connection nodes and requires no supports, resulting in less wet work and higher environmental friendliness and efficiency, significantly leveraging the advantages of prefabricated structures.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
