Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a fully prefabricated concrete modular building. Background Art

[0002] Concrete modular buildings are becoming more and more widely used, but they currently have the following disadvantages:

[0003] (1) The building is constructed by stacking prefabricated space modules layer by layer. The non-load-bearing walls in the prefabricated space modules also passively participate in the structural stress, resulting in an unclear force transmission path of the building structure system. After completion, the non-load-bearing walls are prone to cracking due to stress.

[0004] (2) Prefabricated space modules are large in size and are prone to being over-high or over-wide during transportation, which makes transportation difficult;

[0005] (3) Prefabricated space modules are heavy and require high standards for transportation roads and lifting equipment, which significantly increases transportation and lifting costs;

[0006] (4) When prefabricated space modules are prefabricated, a large number of connection cavities need to be reserved, and the connection nodes are complex, which makes the construction process complicated and increases costs. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the utility model provides a fully prefabricated concrete modular building, which reduces the size and weight of the prefabricated modules, facilitates prefabrication and assembly, reduces the overall cost of the building, and makes the force transmission path of the structural system "equivalent to cast-in-place".

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A fully precast concrete modular building, which is assembled from precast modules including planar splicing modules and / or spatial splicing modules and / or a plurality of single precast structural components;

[0010] The plane splicing module includes a side wall module, which is prefabricated as a whole by integrating the side wall and the beam prefabricated parts. The side wall includes a non-load-bearing wall and / or a vertical structural member. The plane splicing module also includes a floor module.

[0011] The spatial splicing module is prefabricated as a whole from a plurality of the side wall modules and an upper cover and / or a lower cover, wherein the upper cover or the lower cover includes a floor slab and / or a structural beam;

[0012] The single structural component prefabricated parts include beam prefabricated parts, structural column prefabricated parts, and shear wall prefabricated parts;

[0013] The planar modules, spatial modules, and individual prefabricated structural components are each pre-reinforced with reinforcement and / or connectors. The fully precast concrete modular building is assembled using a method whereby the prefabricated modules are first connected by reinforcement and / or connectors, followed by cast-in-place connections at several cast-in-place joint areas. This approach aims to facilitate construction and reduce costs by appropriately utilizing localized cast-in-place, or "wet-joining," methods compared to overemphasizing "dry-joining."

[0014] Preferably, the vertical structural member of the side wall module includes a load-bearing wall, which is a wall that bears vertical and / or horizontal actions, including a reinforced concrete shear wall or a part of a reinforced concrete shear wall.

[0015] Preferably, the vertical structural member of the side wall module further comprises a structural column or a portion of a structural column, and the structural column or a portion of the structural column is prefabricated integrally with other components of the side wall module.

[0016] Preferably, the height of the non-load-bearing wall is determined by leaving a 2mm to 30mm gap between it and the lower or upper components after assembly. After the building structure system is assembled, grouting is injected into the gap to achieve connection and waterproofing between it and the upper or lower components. This approach aims to cut off the force transmission path between the non-load-bearing wall and the load-bearing components, leaving the non-load-bearing wall to serve only a partitioning or enclosure function. Furthermore, post-grouting ensures a tight connection between the non-load-bearing wall and its connected components, ensuring good waterproofing.

[0017] Preferably, the cast-in-place splicing area includes a vertical cast-in-place splicing area and a horizontal cast-in-place splicing area; the vertical cast-in-place splicing area is arranged at the corners of the building grid, including but not limited to; the horizontal cast-in-place splicing area is arranged at the overlapping layer, including but not limited to the beam prefabricated parts.

[0018] Preferably, the floor slab module is connected to the side wall module or the space splicing module or a single beam prefabricated part at the overlapping layer of the beam prefabricated part through reinforcement.

[0019] Preferably, the method for connecting the floor slab module with the space splicing module includes: the reinforcement of the floor slab module is anchored into the overlapping layer of the beam prefabricated parts of the space splicing module; the width of the beam prefabricated parts is greater than the thickness of the non-load-bearing walls and load-bearing walls prefabricated thereon as a whole, and an overlapping layer is reserved on the side connected to the floor slab module.

[0020] Preferably, the method for connecting the floor slab module and the space splicing module further comprises: reinforcing bars are provided on both the floor slab module and the space splicing module, and then a horizontal cast-in-situ connection area is provided on the floor slab for connection.

[0021] Preferably, the plane splicing module and / or the space splicing module completes all or part of its decoration and / or water and electricity installation works during the prefabrication stage.

[0022] Compared with the prior art, the beneficial effects of the present invention include:

[0023] (1) The entire building is divided into plane-jointed modules and space-jointed modules. Plane-jointed modules are used for large bays, meaning the side walls, floor, and roof of the bay are prefabricated separately and then assembled on-site. Space-jointed modules are used for small bays, such as bathrooms, which are prefabricated as a whole and then assembled on-site with the plane-jointed modules. This approach can reduce the size and weight of prefabricated modules, making them easier to transport, hoist, and assemble on-site.

[0024] (2) For large building spans, they are not divided according to specific components during prefabrication, but are divided into flat splicing modules according to the planes that make up the building space. This can simplify the on-site splicing process and reduce the splicing connection cost.

[0025] (3) For small building bays, such as bathrooms, they are prefabricated as a whole according to the space splicing modules during prefabrication, which solves the problems of small bay components being small, trivial, complex in connection, and prone to water leakage. In addition, they can be decorated, renovated, and installed with water and electricity in an integrated manner, which can reduce the amount of on-site construction work and is conducive to improving the quality of the project.

[0026] (4) Cut off the force transmission path between non-load-bearing walls and load-bearing components, so that non-load-bearing walls only perform the function of partitioning or enclosure. At the same time, through post-grouting, they are tightly connected to the connected components to ensure good waterproofing. This approach makes the force transmission path of the structural system clear and the structural force is "equivalent to cast-in-place". Therefore, this technology can be applied not only to multi-story buildings, but also to high-rise buildings.

[0027] (5) The plane splicing module and the space splicing module adopt the method of cast-in-place connection in the cast-in-place connection area. The connection method is simple and reliable, convenient for construction and conducive to reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

Although the accompanying drawings show exemplary embodiments of the present invention, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, 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.

[0051] like Figures 1 to 3 As shown, the present invention provides a fully precast concrete modular building, which is assembled from prefabricated modules, including a planar splicing module 1, a spatial splicing module 2, and a plurality of individual prefabricated structural components. In this embodiment, the individual prefabricated structural component is a prefabricated beam 3, and the prefabricated module also includes a prefabricated staircase 10. This embodiment only includes a single prefabricated beam, but other embodiments may include multiple prefabricated beams and / or multiple prefabricated structural columns.

[0052] In the accompanying drawings, Figure 1 To splice the plan, Figure 2 and Figure 3 They are respectively a building plan and a structural plan. After being spliced ​​by the method of the utility model, the building can achieve the designed use function, the structure can meet the safety and reliability requirements, and the structural system is "equivalent to cast-in-situ".

[0053] like Figures 4 to 9As shown, the planar splicing module 1 includes a side wall module 11, which is prefabricated integrally with the side wall and prefabricated beam members 4. The side wall includes a non-load-bearing wall 8 and vertical structural members. The vertical structural members include load-bearing walls, including but not limited to reinforced concrete shear walls or portions of reinforced concrete shear walls. This embodiment does not include shear walls or other load-bearing walls. The vertical structural members also include structural columns 5 or portions of structural columns 51, which are prefabricated integrally with the other components of the side wall module. The side wall module 11 also includes doors, windows, or openings therein, as well as aisle openings.

[0054] The plane splicing module 1 further includes a floor module 12. In this embodiment, the floor module 12 is a fully prefabricated floor;

[0055] like Figure 1 and Figures 10-11 As shown, the spatial module 2 is prefabricated from several sidewall modules 11 and an upper and / or lower cover. In this embodiment, the spatial module 2 includes a bathroom module 21, a kitchen module 22, and a balcony module 23. Taking the bathroom module 21 as an example, it is prefabricated from four "wall-beam integrated" sidewall modules and a lower cover. The lower cover includes the bathroom floor and a structural beam running through it. In this embodiment, the sidewall modules of the bathroom module 21 also include a single structural column 52 prefabricated integrally with the sidewall modules.

[0056] like Figure 5 、 Figure 7 、 Figure 9 、 Figure 11 As shown, the height of the non-load-bearing wall 8 is determined by leaving a gap of 2mm to 30mm between it and the lower or upper components after assembly. After assembly, the bottom of the non-load-bearing wall 8 does not directly contact the lower component or the top does not directly contact the upper component. A gap Δ is reserved so that the non-load-bearing wall 8 does not participate in the structural stress but only plays a dividing or enclosing role. In this embodiment, the reserved gap Δ is 5mm. The reserved gap Δ of the non-load-bearing wall 8 in the plane splicing module 1 is reserved at the bottom of the prefabricated module, and the reserved gap Δ of the non-load-bearing wall 8 in the space splicing module 2 is reserved at the top of the prefabricated module. After the assembly of the building structure system is completed, grouting is injected into the reserved gap to achieve connection and waterproofing between the non-load-bearing wall 8 and the upper or lower components.

[0057] like Figures 1 to 16As shown, the planar splicing module 1, the spatial splicing module 2, and the single prefabricated beam 3 all have pre-reinforced reinforcement 6 or connectors 7. In this embodiment, the non-load-bearing wall reinforcement 61, the structural column reinforcement 62, the prefabricated beam bottom reinforcement 63, the prefabricated beam stirrup reinforcement 64, the prefabricated beam reinforcement 65 corresponding to the floor module, and the floor module reinforcement 66 are arranged according to actual needs, and the reinforcement lengths are based on design requirements. The connectors 7 in this embodiment are divided into screw connectors 71 and nut connectors 72. In other embodiments, the connectors 7 may be grouting sleeves or other types of connectors. This utility model does not limit the type of connector.

[0058] The planar splicing modules 1, spatial splicing modules 2, and prefabricated beam components 3 are first connected via reinforcement bars 6 and / or connectors 7, and then cast-in-situ splicing at several cast-in-situ splicing areas 9. These cast-in-situ splicing areas 9 include vertical cast-in-situ splicing areas 91 and horizontal cast-in-situ splicing areas 92. Vertical cast-in-situ splicing areas 91 can be located at, but not limited to, the corners of building sections; horizontal cast-in-situ splicing areas 92 can be located at, but not limited to, the overlapping layers of prefabricated beam components. The placement of these cast-in-situ splicing areas should be determined based on the actual splitting and splicing plan.

[0059] like Figure 12 As shown, when the floor module 12 is connected to the space splicing module 2, the width of the prefabricated beam 4 in the space splicing module 2 is greater than the thickness of the non-load-bearing wall and load-bearing wall prefabricated integrally therewith. The side where the prefabricated beam 4 is connected to the floor module 12 reserves a laminated layer 41 for connection to the reinforcement 66 of the floor module 12. In this embodiment, the space splicing module 2 is a bathroom space splicing module 21.

[0060] like Figure 13 As shown, the method of connecting the floor module 12 to the space splicing module 2 further includes: ribs 66 of the floor module 12 and ribs 65 of the prefabricated beams of the space splicing module 2, and then connecting them at a horizontal cast-in-place connection area 92 provided on the floor. In this embodiment, the space splicing module 2 is a bathroom space splicing module 21.

[0061] like Figure 14 As shown, the floor slab modules 12 are connected to the beam prefabricated members 3 or the beam prefabricated members 4 in the side wall modules 11 at the overlapping layers via ribs 66, and simultaneously interconnect adjacent floor slab modules 12. In this embodiment, the beam prefabricated members are the beam prefabricated members 4 in the side wall modules.

[0062] like Figures 15-16 As shown, the bottom reinforcement 63 at both ends of the single beam prefabricated component 3 is connected to the structural column 5; and the stirrup reinforcement 64 at the beam composite layer 41 is connected to the floor module 12.

[0063] According to the present invention, the flat-panel module 1 and the spatial-panel module 2 can have all or part of their decoration and / or plumbing and electrical installation completed during the prefabrication phase. In this embodiment, the spatial-panel module 2 has all of its decoration and electrical installation completed except for the splicing locations. The flat-panel module 1 has some of its decoration and electrical installation completed based on the actual splicing requirements.

[0064] This application splits the entire building into plane splicing modules and space splicing modules, which can reduce the size and weight of the prefabricated modules, facilitate transportation, lifting and on-site splicing, and reduce the overall cost of the building. It has obvious advantages over existing technologies.
