Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building construction, and in particular to a concrete module structural system and a construction method thereof. Background Art

[0002] Prefabricated buildings, with their short construction cycles and minimal environmental impact, have become a key focus for achieving green buildings and industrialization. Modular buildings, among them, offer the highest assembly rate and highest degree of industrialization. Currently, there are two main types of modular buildings: steel modular buildings and concrete modular buildings. While concrete modular buildings are cheaper than steel structures, they also present challenges such as inconvenient connections and difficulty in on-site rebar tying.

[0003] The existing patent proposes a concrete module wall formwork (CN218933525U) system. In this system, the prefabricated wall (wall formwork) is relatively thin, which greatly reduces the weight of the module, but also brings the following problems: First, the shear wall steel bars are set in the cast-in-place part of the shear wall. The steel truss is easy to collide with the shear wall steel bars during on-site binding, resulting in low steel bar binding efficiency; second, horizontal pressure is generated during concrete pouring. Setting a tensioning device between a pair of prefabricated walls can enhance the horizontal compressive strength and rigidity of the prefabricated wall, but the tensioning device needs to pass through one side of the prefabricated wall and be pre-tightened by screws. Multiple tensioning devices pass through the prefabricated wall, making it difficult to decorate the prefabricated wall on that side, affecting construction efficiency; third, the steel truss is only set on one side of the prefabricated wall, and the combined effect of the prefabricated wall on the other side without the steel truss and the cast-in-place concrete wall is limited, and the stress-bearing performance of the modular structural system is poor.

For example, "fix" can mean fixed connection, detachable connection, or integration; "connection" can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0073] See also Figures 1 to 4The present invention provides a concrete module structure system, which includes a prefabricated wall main module 1, a prefabricated wall sub-module 2, a concrete cast-in-place wall 4, a plurality of clamping members, a plurality of connecting members 3 and a plurality of shear members 22; a plurality of clamping members are provided on the prefabricated wall sub-module 2 and the prefabricated wall main module 1, and the connecting member 3 is clamped with a pair of clamping members so that the connecting member 3 can limit the lateral movement of the prefabricated wall sub-module 2 and the prefabricated wall main module 1; a plurality of connecting members 3 are arranged in a longitudinal array; the prefabricated The wall submodule 2 and the precast wall main module 1 enclose a cavity, within which a cast-in-place concrete wall 4 is disposed. Baffles can be attached to the precast wall submodule 2 and the precast wall main module 1 to enclose the cavity for subsequent concrete pouring. The precast wall main module 1, precast wall submodule 2, clips, and connectors 3 are all connected to the cast-in-place concrete wall 4. Multiple shear members 22 are arranged in an array along the longitudinal and height directions. One end of the shear member 22 is connected to the precast wall submodule 2, and the other end is connected to the cast-in-place concrete wall 4. The precast wall main module 1, precast wall submodule 2, and cast-in-place concrete wall 4 together form a shear wall. The transverse direction refers to the direction perpendicular to the wall surface of the precast wall main module 1 and precast wall submodule 2, while the longitudinal direction refers to the horizontal direction parallel to the wall surface of the precast wall main module 1 and precast wall submodule 2. The transverse and longitudinal directions lie in the same horizontal plane. The height direction refers to the direction perpendicular to the horizontal plane, i.e., the axial direction of the vertical reinforcement 121.

[0074] The clips are integrally cast with the prefabricated wall sub-module 2 or the prefabricated wall main module 1, the shear members 22 are integrally cast with the prefabricated wall sub-module 2, the connectors 3 are prefabricated in the factory, and the steel bar binding or welding work is all completed in the factory. The construction site only needs simple modular splicing and concrete pouring, which greatly reduces the workload on the construction site and improves the assembly efficiency of modular buildings.

[0075] During construction, the prefabricated wall main module 1 and the prefabricated wall sub-module 2 are hoisted close to each other, and the connecting piece 3 is engaged with a pair of clamping pieces (clamping connection) to fix the prefabricated wall main module 1 and the prefabricated wall sub-module 2 to form a tension structure, which prevents the prefabricated wall from being damaged or deformed greatly during concrete pouring, and enhances the horizontal compressive strength of the concrete module structure system during concrete pouring; and the clamping piece is pre-embedded in the prefabricated wall main module 1 or the prefabricated wall sub-module 2, and does not penetrate the wall surface of the prefabricated wall main module 1 or the prefabricated wall sub-module 2 on the side facing away from the concrete cast-in-place wall 4, that is, the outer wall of the prefabricated wall, and will not affect the construction of the working surface of the outer wall of the prefabricated wall. There is no need to repair the penetration point of the outer wall of the prefabricated wall, and the construction of the working surface of the outer wall of the prefabricated wall can be carried out simultaneously with the pouring and solidification of the concrete, thereby shortening the construction period.

[0076] After the concrete cast-in-place wall 4 is cast and formed, the shear member 22 is connected to the concrete cast-in-place wall 4. The force of the precast wall sub-module 2 can be effectively transmitted to the precast wall main module 1 through the shear member 22 and the concrete cast-in-place wall 4, thereby improving the combined force of the precast wall sub-module 2 and the concrete cast-in-place wall 4, fully utilizing the material bearing capacity of the precast wall, and further enhancing the stress stability of the concrete module structural system. It should be noted that the steel truss is the main load-bearing structure of the concrete module structural system. A shear wall steel mesh is also embedded in the shear wall. The role of the shear wall steel mesh is to improve the stress stability of the shear wall and transmit the force of the shear wall to the steel truss. In traditional construction methods, the problem of limited bearing capacity of the precast wall sub-module 2 is solved by tying steel bars between the precast wall main module 1 and the precast wall sub-module 2. However, the steel truss needs to be anchored into the shear wall and tied or welded to the built-in shear wall steel mesh, which increases working hours and construction costs. The existing patent proposes a non-dismantling concrete module wall formwork (CN218933525U), which connects two shear walls by setting a tensioning device. However, the tensioning device is only provided with truss reinforcement on one side, and the other side is a screw rod passing through the shear wall. The screw rod has weak compression and shear resistance, resulting in limited bearing capacity of the shear wall on the side where the screw rod passes through, and poor stress-bearing effect of the module combination.

[0077] During the prefabrication phase, the present invention ties or welds the steel cage 12 to the shear wall reinforcement mesh embedded in the prefabricated wall main module 1, that is, to the first reinforcement mesh 14. The complex tying and welding operations are completed during the factory prefabrication phase. After shipment to the construction site, only simple docking and pouring operations are required, making construction more convenient and efficient, significantly reducing on-site work hours. Shear members 22 are embedded in the prefabricated wall submodule 2. After concrete is formed, they can bond to the shear members 22, allowing the forces acting on the prefabricated wall submodule 2 to be effectively transmitted to the prefabricated wall main module 1 via the shear members 22, the cast-in-place concrete wall 4, and the steel cage 12, thereby enhancing the stress stability of the concrete module structural system. Furthermore, compared to tying steel bars between the prefabricated wall main module 1 and the prefabricated wall submodule 2, the cost of the clips, connectors 3, and shear members 22 is lower, saving construction costs.

[0078] In the first embodiment, as Figures 5 to 9As shown, the connecting member 3 includes an operating rod 37, a connecting plate 31, and a pair of wedge blocks 32. The top of the connecting plate 31 is connected to the operating rod 37. The two sides of the bottom end of the connecting plate 31 are connected to the pair of wedge blocks 32 in a one-to-one correspondence. The clamping member is a clamping plate 13, and the pair of clamping plates 13 are provided on the prefabricated wall sub-module 2 and the prefabricated wall main module 1 in a one-to-one correspondence. The wedge blocks 32 are clamped to the clamping plates 13. The shape of the wedge blocks 32 can be cylindrical, square, or conical. The bottom ends of the wedge blocks 32 are chamfered to facilitate the clamping of the wedge blocks 32. In this embodiment, the clamping plate 13 is an L-shaped clamping plate, which includes a vertical clamping plate and a horizontal clamping plate connected vertically. The vertical clamping plate is embedded in the prefabricated wall main module 1. One end of the horizontal clamping plate is embedded in the prefabricated wall main module 1, and the other end extends to the side of the prefabricated wall sub-module 2. Compared with ordinary steel plates, bending or welding the steel plates into L-shaped clips can effectively improve the gripping force between the clips 13 and the prefabricated wall sub-modules 2 or the prefabricated wall main modules 1, and improve the limiting strength and compressive and shear strength of the clips 13.

[0079] See also Figure 9 The horizontal clamping plate is provided with a socket 131, into which a wedge 32 can be inserted vertically, enabling a quick connection between the precast wall main module 1 and the precast wall submodule 2, forming a tensioning structure. The clamping member and connector 3 effectively improve the horizontal compressive strength of the concrete modular structure, eliminating the need for temporary reinforcement at the construction site and significantly improving construction efficiency. The connector 3, in conjunction with the cast-in-place concrete wall 4, also improves the shear strength of the concrete modular structure to a certain extent. When used in conjunction with the shear member 22, this further enhances the shear strength of the concrete modular structure.

[0080] Furthermore, a threaded joint 33 is provided at the top of the connecting plate 31; a threaded rod is correspondingly provided at the bottom end of the operating rod 37; and the threaded rod is threadedly connected to the threaded joint 33. The operating rod 37 can be reserved in the concrete cast-in-place wall 4 to serve as a rebar, or the operating rod 37 can be removed and recycled before pouring concrete by a detachable connection. In this embodiment, by threading the operating rod 37 to the connecting plate 31, the operating rod 37 can be moved in the height direction when the two are connected, so that the wedge block 32 can be inserted into the cavity and inserted into the card plate 13. The length of the operating rod 37 can be set according to actual needs; when the operating rod 37 is recovered, the operating rod 37 is reversed to release the threaded connection between the operating rod 37 and the connecting plate 31. Reserving the operating rod 37 can improve the stress stability of the concrete module structure system, and removing and recovering the operating rod 37 can enable repeated use, saving construction costs.

[0081] In the second embodiment, as Figure 10 and Figure 11As shown, the connector 3 includes a screw 34, an end plate 35, and a nut 36. One end of the screw 34 is connected to the end plate 35, and the other end is threadedly connected to the nut 36. The clamping member is an open ring 23, and a pair of open rings 23 are provided on the prefabricated wall sub-module 2 and the prefabricated wall main module 1, one for each other. The nut 36 is embedded in one open ring 23, and the end plate 35 is embedded in the other open ring 23. The pair of open rings 23 can limit the lateral movement of the connector 3. In other words, the connector 3 can limit the lateral movement of the prefabricated wall main module 1 and the prefabricated wall sub-module 2, thereby improving the horizontal compressive strength of the concrete module structure. In this embodiment, the connector 3 is a threaded connection structure of a bolt and a nut. The open ring 23 is an open square tube. The length of the open ring 23 can be adjusted according to actual needs to limit and guide the connector 3. A stopper can also be welded to the bottom end of the open ring 23 to limit the movement of the connector 3 in the height direction, thereby improving the flexibility of the installation position of the connector 3. The function of the open ring 23 is to limit the end plate 35 or nut 36 laterally, that is, to limit the screw 34 laterally, thereby improving the horizontal compressive strength of the concrete module structure during concrete pouring, enhancing the construction stability and the structural strength of the module structure. In this embodiment, the connector 3 can be moved vertically and snapped into the pair of open rings 23. The opening diameter of the open ring 23 is larger than the outer diameter of the screw 34 and smaller than the outer diameter of the end plate 35 or nut 36, so that the end plate 35 or nut 36 will not be separated from the open ring 23, thus serving as a lateral limiter. Compared to the first embodiment, the connector 3 of the second embodiment can adjust the distance from the end plate 35 by rotating the nut 36, thereby improving the adaptability to the installation of a pair of open rings 23 with different spacings.

[0082] See also Figure 12 The shear member 22 is a convex steel bar. The convex steel bar includes a convex section steel bar and a pair of horizontal section steel bars. The pair of horizontal section steel bars are arranged on both sides of the convex section steel bar in a one-to-one correspondence; the convex section steel bar is connected to the concrete cast-in-place wall 4; the horizontal section steel bar is connected to the prefabricated wall sub-module 2. The shear member 22 can be formed by bending a steel bar, or it can be a shear stud or channel steel. The convex steel bar connects the concrete cast-in-place wall 4 and the prefabricated wall sub-module 2, which can effectively transmit the force; and the convex structure can further enhance the compressive and shear strength of the shear member 22. The setting of the shear member 22 can effectively replace the traditional steel bar binding method, so that the prefabricated wall sub-module 2 participates in the module combination force, while improving the structural strength of the concrete module structure, simplifying the construction process.

[0083] See also Figures 13 to 15The precast wall main module 1 includes a first precast wall 11, a steel cage 12, and a first steel mesh 14; one end of the steel cage 12 is connected to the first steel mesh 14, and the other end is connected to the cast-in-place concrete wall 4; the first steel mesh 14 is pre-buried in the first precast wall 11; and the first precast wall 11 is connected to the cast-in-place concrete wall 4. Specifically, the first steel mesh 14 is a shear wall steel mesh built into the first precast wall 11, and the steel cage 12 can be regarded as a steel truss external to the first precast wall 11 or a steel truss built into the cast-in-place concrete wall 4. The steel cage 12 serves as the main load-bearing structure of the concrete module structural system. The steel cage 12 connects the cast-in-place concrete wall 4 and the first precast wall 11 at the same time. The force acting on the second precast wall 21 can be effectively transmitted to the steel cage 12 through the shear member 22 and the cast-in-place concrete wall 4, thereby enhancing the strength of the module combination. The first prefabricated wall 11, the steel cage 12 and the first steel mesh 14 are all prefabricated in the factory and cast in one piece, which greatly reduces the workload on the construction site and improves construction efficiency.

[0084] like Figures 16 to 18 As shown, the steel cage 12 includes a plurality of stirrups 122 and a plurality of vertical steel bars 121; a plurality of vertical steel bars 121 are welded to the inner side of the stirrups 122; a plurality of stirrups 122 are arranged along the height direction; one end of the stirrup 122 is connected to the first prefabricated wall 11, and the other end is connected to the cast-in-place concrete wall 4; the vertical steel bars 121 are connected to the cast-in-place concrete wall 4. Specifically, one end of the stirrup 122 is integrally cast with the first prefabricated wall 11, and whether to tie the steel bars can be selected according to the strength requirements of the module structure; at the same time, the method of welding the stirrups 122 and the vertical steel bars 121 can replace the traditional method of tying steel bars, greatly improving the convenience of the operation. In this embodiment, a hook is provided at the top of the vertical steel bar 121. The hook is formed by bending the vertical steel bar 121. The hook can be overlapped on the stirrup 122 to improve the stability of the prefabricated wall main module 1 during hoisting and transportation.

[0085] Secondly, the reinforcement cage 12 also includes transverse reinforcement 123; the axis of the transverse reinforcement 123 is parallel to the horizontal direction, and both ends of the transverse reinforcement 123 are connected to the stirrups 122; the transverse reinforcement 123 is welded to the vertical reinforcement 121. In this embodiment, the transverse reinforcement 123 is added to the reinforcement cage 12 at the edge of the cast-in-place concrete wall 4. Compared with the reinforcement cage 12 near the middle of the cast-in-place concrete wall 4, the addition of transverse reinforcement 123 can increase the number of welds to the vertical reinforcement 121, thereby enhancing the mechanical stability of the concrete module structural system at the edge, and thus the overall mechanical stability of the concrete module structural system.

[0086] See also Figures 19 to 21The precast wall submodule 2 includes a second precast wall 21 and a second reinforcement mesh 24. The second reinforcement mesh 24, the connectors, and the shear members 22 are all embedded within the second precast wall 21. The second precast wall 21 is connected to the cast-in-place concrete wall 4. In this embodiment, the two free ends of the second reinforcement mesh 24 are bent to form bent ends. These bent ends can be embedded in the cast-in-place concrete wall 4 after concrete pouring, further enhancing the structural strength of the concrete module system. Among them, the second steel mesh 24, the clips, and the shear members 22 are integrally cast with the second precast wall 21 in the factory. After the clips are connected to the connector 3, the horizontal compressive strength of the second precast wall 21 can be increased, and the steel bar binding operation can be replaced, reducing the work intensity. In addition, the clips and the shear members 22 do not penetrate the second precast wall 21, and will not affect the construction work on the side of the second precast wall 21 away from the concrete cast-in-place wall 4. During the period when the concrete cast-in-place wall 4 is waiting to solidify, the construction work on the side of the second precast wall 21 away from the concrete cast-in-place wall 4 can be carried out simultaneously, shortening the construction time. The first steel mesh 14 is similar and will not be repeated. The second steel mesh 24 and the shear members 22 can both enhance the compressive and shear strength of the second precast wall 21, effectively transfer the force to the concrete cast-in-place wall 4 and the steel cage 12, and improve the combined force strength of the modular structural system.

[0087] In addition, the present invention also provides a construction method of a concrete module structural system. The construction method of the concrete module structural system is implemented based on the above concrete module structural system, and the construction method includes:

[0088] Prefabrication: The prefabricated wall main module 1, prefabricated wall submodule 2, snap-fit ​​components, connectors 3, and shear members 22 are all prefabricated in the factory. The snap-fit ​​components are integrally formed on the prefabricated wall main module 1 and the prefabricated wall submodule 2. The shear member 22 is connected to the prefabricated wall submodule 2 during the integral molding process. The connector 3 is reserved for future use.

[0089] Specifically, when preparing the prefabricated wall main module 1, the first steel mesh 14 and the steel cage 12 are first constructed, and the first steel mesh 14 and the steel cage 12 are tied or welded together, and concrete is poured to form the first prefabricated wall 11; wherein the steel cage 12 substantially covers the width of the cast-in-place concrete wall 4 in the horizontal direction, thereby improving the structural stability of the concrete module structure system; when preparing the prefabricated wall sub-module 2, the second steel mesh 24 is first constructed, and the prefabricated shear members 22 are fixed to a preset position, and concrete is poured to form the second prefabricated wall 21. The above steps are all completed in the factory, and each module is prefabricated in advance, which simplifies the installation process on the construction site and improves construction efficiency.

[0090] Construction: Splice the prefabricated wall main module 1 and the prefabricated wall sub-module 2 and connect and fix them with the connector 3. Specifically, hoist the first prefabricated wall 11 and the second prefabricated wall 21 to the preset position, move the clamping parts closer to each other, and lower the connector 3 to engage with the pair of clamping parts.

[0091] The periphery of the first precast wall 11 and the second precast wall 21 is sealed, leaving only the top opening for pouring concrete; concrete is poured into the cavity, and after the concrete solidifies, a cast-in-place concrete wall 4 is formed; wall painting, carving and other operations can be carried out simultaneously on the first precast wall 11 and the second precast wall 21.

[0092] By prefabricating each module in a factory and transporting it to the construction site, the present invention requires only simple construction, significantly simplifying the construction process, saving construction time, and improving construction efficiency. The concrete modular structural system, pre-embedded with a steel cage 12 and shear members 22, effectively combines the prefabricated wall with the cast-in-place concrete wall 4, effectively sharing the load, fully utilizing the material properties, improving the combined load-bearing effect, and effectively saving construction costs.
