Description

Technical Field

[0001] The present invention relates to the technical field of assembled walls, and in particular to an assembled curved wall and a construction method thereof. Background Art

[0002] With the development of the construction industry, people's requirements for buildings are no longer limited to regular shapes. Curved buildings with more artistic value are constantly emerging. However, the prerequisite for manufacturing curved components on the construction site is to first manufacture templates that meet the requirements. This greatly increases the difficulty of on-site construction and reduces efficiency. In addition, the curved templates made on site have low precision and poor quality. Therefore, it is necessary to choose a more efficient way to produce curved components.

[0003] Prefabricated construction is a construction method in which prefabricated components are produced in factories and assembled on-site. Its standardized and efficient manufacturing features give it the advantages of high efficiency and high quality. However, most prefabricated components produced in factories are of a single form and fixed size, which cannot meet the requirements of efficient manufacturing of various types of components, especially curved components. There are also some difficulties in the on-site installation of curved prefabricated components. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an assembled curved wall that is efficient to manufacture and easy to assemble, thereby reducing the difficulty of construction at the construction site.

[0005] Another object of the present invention is to provide a construction method for the above-mentioned prefabricated curved wall.

[0006] The technical solution of the present invention is: a prefabricated curved wall comprising a wall body and a steel mesh. The wall body has curved sidewalls, a filling cavity is defined in the middle of the wall body, and the steel mesh is partially located within the wall body and partially exposed within the filling cavity. A plug-in portion is provided on one side of the wall body, and a plug-in slot is provided on the other side of the wall body. The plug-in portion engages with the plug-in slot on the other wall body and is secured by bolts. The filling cavity within the wall body reduces the weight of the wall body and facilitates transportation and assembly. Concrete pouring can be carried out after the splicing is completed on the construction site, thereby improving construction efficiency and the integrity of the prefabricated wall body.

[0007] Furthermore, the surface of the wall, the plug-in portion and the plug-in slot are respectively provided with bolt holes.

[0008] Furthermore, the wall is provided with a receiving hole corresponding to the bolt hole recess. The receiving hole is used to receive the end of the bolt or the nut. The depth of the receiving hole is greater than the thickness of the bolt end and the thickness of the nut. This ensures that the bolt end and the nut do not protrude from the wall surface, thereby preventing the smooth curved surface of the wall from being damaged during plastering and decoration of the wall facade.

[0009] Furthermore, the steel mesh includes a steel surface layer and connecting steel bars. The steel surface layer is located inside the side wall of the wall. Both ends of the connecting steel bars are respectively connected to the steel surface layers on both sides, and the connecting steel bars are exposed in the filling cavity.

[0010] Furthermore, the reinforcement surface layer includes transverse curved bars and longitudinal bars. The transverse curved bars extend along the length of the wall, and the longitudinal bars connect multiple transverse curved bars along the longitudinal direction. The ends of the connecting bars are connected to the junctions between the transverse curved bars and the longitudinal bars. The transverse curved bars extend along the length of the wall to prevent cracking during manufacturing and transportation.

[0011] Furthermore, the connecting steel bars include horizontal steel bars and inclined steel bars, one end of the horizontal steel bars and the inclined steel bars are connected together, and the other ends are respectively connected to different heights of the longitudinal steel bars.

[0012] Furthermore, the plug-in portion protrudes from one side of the wall, and a cavity is provided in the plug-in portion, which is communicated with the filling cavity. During pouring, the cavity can be filled with concrete to ensure the strength of the plug-in portion.

[0013] Furthermore, the slot is recessed from one side of the wall into the filling cavity, leaving a gap between the sidewall of the slot and the sidewall of the wall. During pouring, the gap can be filled with concrete, making the two walls, including the steel mesh and bolt connections, a solid whole, improving the connection strength and integrity between the components.

[0014] Another technical solution of the present invention is: the construction method of the above-mentioned prefabricated curved wall is to first model the wall in a modeling software, prefabricate a steel mesh in the factory according to the wall form, and 3D print the model on the steel mesh to form a prefabricated prefabricated curved wall. The middle part of the wall is a filling cavity. The wall is transported to the construction site for assembly, and the plug-in part is inserted into the plug-in slot of another wall. The plug-in part and the plug-in slot are fixed by bolts, and finally concrete is poured in the filling cavity to form the two adjacent walls into a unified component.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The assembled curved wall of the present invention is first prefabricated in the factory. The wall has a cavity structure, which is convenient for transportation and installation. During construction, it only needs to be spliced ​​and fixed with bolts for pouring. At the same time, the wall structure is modeled by modeling software and produced by 3D printing. There is no need to make a separate mold, which improves construction efficiency and saves costs. In addition, the assembled components produced in the factory have more accurate dimensions. Compared with the walls cast on site, the material consumption is reduced and the quality is also improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below with reference to the examples, but the embodiments of the present invention are not limited thereto.

[0023] Example

[0024] like Figure 1 and Figure 2 As shown, this embodiment provides an assembled curved wall, including a wall 1 and a steel mesh 2.

[0025] like Figure 1 and Figure 3 As shown, the sidewalls of the wall are curved, and a filling cavity 3 is provided in the middle of the wall. The steel mesh is partially located within the wall and partially exposed in the filling cavity. A plug-in portion 4 is provided on one side of the wall, and a plug-in slot 5 is provided on the other side of the wall. The plug-in portion plugs into the plug-in slot on the other wall and is fixed by bolts 8. The interior of the wall is a filling cavity, which reduces the weight of the wall and facilitates transportation and assembly. Concrete pouring can be carried out after the splicing is completed on the construction site, which can improve construction efficiency and the integrity of the prefabricated wall.

[0026] like Figure 1 、 Figure 3 and Figure 4As shown, the surface of the wall, the plug-in portion and the plug-in slot are respectively provided with bolt holes 6, and the wall is recessed with a receiving hole 7 corresponding to the bolt hole. The receiving hole is used to receive the end of the bolt or the nut, and the depth of the receiving hole is greater than the thickness of the bolt end and the thickness of the nut. Ensure that the end of the bolt and the nut do not protrude from the surface of the wall to avoid damaging the smooth curved surface of the wall when the wall facade is plastered or decorated. The plug-in portion protrudes from one side of the wall, and a cavity is provided in the plug-in portion, which is connected to the filling cavity. During pouring, the cavity can be filled with concrete to ensure the strength of the plug-in portion. The plug-in slot is recessed inward from one side of the wall into the filling cavity, and a gap is left between the side wall of the plug-in slot and the side wall of the wall. During pouring, concrete can be filled in the gap, so that the two walls including the steel mesh and the bolt connection become a hard whole, thereby improving the connection strength and integrity between the components.

[0027] like Figure 1 and Figure 2 As shown, the steel mesh includes a steel surface layer and connecting steel bars 21. The steel surface layer is located inside the side wall of the wall. The two ends of the connecting steel bars are respectively connected to the steel surface layers on both sides. The connecting steel bars are exposed in the filling cavity. The steel surface layer includes transverse curved bars 22 and longitudinal steel bars 23. The transverse curved bars extend along the length of the wall. The longitudinal steel bars are connected to multiple transverse curved bars along the longitudinal direction. The two ends of the connecting steel bars are respectively connected to the connection points of the transverse curved bars and the longitudinal steel bars. The transverse curved bars extend along the length of the wall to prevent the wall from cracking during manufacturing and transportation. The connecting steel bars include horizontal steel bars and inclined steel bars. One end of the horizontal steel bars and the inclined steel bars are connected together, and the other ends are respectively connected to different heights of the longitudinal steel bars. The steel bars are arranged at intervals and interconnected to play a role in resisting tension and cracking of the concrete wall. The form of the steel mesh is the same as that of the wall, ensuring that the steel bars and concrete can work together well.

[0028] The construction method of the above-mentioned prefabricated curved wall,

[0029] The initial model was first built in Rhino 3D modeling software. The model size was approximately 0.4m×0.1m×0.1m. The model built according to the target structure was saved and exported in STL format.

[0030] Tie the steel mesh according to the form of the component and arrange the steel mesh in the working area of ​​the 3D printer.

[0031] Import the model file into the 3D printer and print the curved wall on the steel mesh to form a prefabricated assembled curved wall.

[0032] The middle part of the wall is the filling cavity. The wall is transported to the construction site for assembly. The plug-in part is inserted into the plug-in slot of the other wall, and the plug-in part and the plug-in slot are fixed by bolts. Finally, concrete is poured in the filling cavity. The concrete simultaneously fills the joints and joint gaps of the two walls and wraps the bolts, so that the two adjacent walls form a unified component.

[0033] As described above, the present invention can be better implemented. The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention.
