[0006] The industrialized building based on the DFMA design method provided in this application adopts the following technical solutions: An industrialized building based on the DFMA design method comprises a floor slab, a wall slab and a hollow tube arranged in the floor slab and the wall slab, wherein a pipeline can be run in the hollow tube, and an end of the hollow tube extends to a side or side edge of the floor slab and the wall slab and the end thereof is perpendicular to the side or side edge of the floor slab and the wall slab; Among them, a locking device is arranged between the ends of adjacent hollow tubes, and the locking device includes a sliding locking tube and a magnetic control component. The sliding locking tube is slidably connected to the inner wall of the hollow tube, and the magnetic control component can control the sliding locking tube to move between adjacent hollow tubes so as to connect and lock the adjacent hollow tubes using the sliding locking tube, and the magnetic control component can control the sliding locking tube to move completely into a hollow tube so that the floor slab and the wall panel can move in a direction perpendicular to the axis of the hollow tube.

[0007] By adopting the above technical solutions, the industrialized building based on the DFMA design method realizes modular design and efficient assembly. Specifically, by arranging hollow tubes inside the floor slabs and wall panels, and extending the ends of the hollow tubes to the sides or sides of the floor slabs and wall panels, it is convenient to arrange the pipelines. At the same time, by arranging a locking device, convenient connection and separation between the hollow tubes can be achieved, and convenient connection and separation between adjacent wall panels or adjacent floor slabs and adjacent floor slabs and wall panels can be achieved through the connection of the hollow tubes. The sliding locking tube can slide between adjacent hollow tubes under the action of the magnetic control component to complete the connection and locking operation, which improves the assembly efficiency and ensures the connection reliability; the magnetic control component can also control the sliding locking tube to move completely into a hollow tube, allowing the floor slabs and wall panels to move freely in a direction perpendicular to the axis of the hollow tube when needed, which enhances the flexibility and adaptability of the disassembly and assembly of the entire building system. The present application scheme realizes convenient connection and separation between adjacent wall panels or adjacent floor panels and adjacent floor panels and wall panels through hollow tubes that can integrate pipelines, which can effectively reduce connection nodes, reduce external pipeline installation, simplify the assembly process, reduce the workload of on-site construction, and improve construction speed and safety.

[0008] Optionally, the magnetic control component includes a first permanent magnet fixed to the inner wall of a hollow tube and a first electromagnet fixed to the inner wall of an adjacent hollow tube, the sliding locking tube is a second permanent magnet, the first permanent magnet and the second permanent magnet are magnetically connected, when the first electromagnet is energized, the magnetic force between the first electromagnet and the second permanent magnet is greater than the magnetic force between the first permanent magnet and the second permanent magnet so as to move the second permanent magnet between adjacent hollow tubes, a first locking piece is arranged between the sliding locking tube and the adjacent hollow tube, and an unlocking piece for releasing the lock of the first locking piece is arranged on the inner side of the hollow tube.

[0009] By adopting the above technical solution, in the unlocked state, the first permanent magnet and the second permanent magnet are magnetically attracted, and the floor and wall panels can be normally disassembled and assembled; when locking is required, the first electromagnet is energized to move the second permanent magnet between adjacent hollow tubes, and the first locking member is used to lock the adjacent hollow tubes to achieve the connection and fixation between the wall and floor panels; when unlocking is required, the unlocking member is used to unlock the first locking member, and then the first permanent magnet is used to completely move the second permanent magnet into a hollow tube to achieve disassembly. This application solution simplifies the assembly process and improves assembly speed and safety.

[0011] By adopting the above technical solution, the locking block can lock and limit the axial displacement of the hollow tube. Since the axial force on the wall panels and floor slabs is small after installation, the locking force requirement can be met by the locking block at this time. The force on the wall panels and floor slabs along the radial direction of the hollow tube is large. At this time, a high-strength sliding locking tube can be used to ensure the locking effect between the two and enhance the connection stability.

[0012] Optionally, the unlocking member is a second electromagnet, and the locking block is a first magnetic body. When the second electromagnet is energized, the second electromagnet and the first magnetic body are magnetically attracted to each other to move the locking block out of the locking groove. The magnetic force between the first permanent magnet and the second permanent magnet is greater than the magnetic force between the second permanent magnet and the second electromagnet, and when the first electromagnet is de-energized, the locking sliding tube can be completely moved back into a hollow tube.

[0013] By adopting the above technical solution, after the first electromagnet is powered off, due to the magnetic attraction between the first permanent magnet and the second permanent magnet, the locking sliding tube has a tendency to move closer to the first permanent magnet, but at this time the locking block is stuck in the locking groove, which makes the adjacent hollow tubes further reinforced and locked; when unlocking is required, the first electromagnet is powered off and the second electromagnet is powered on, so that the locking block can be moved out of the locking groove. Under the magnetic attraction of the first permanent magnet and the second permanent magnet, the sliding locking tube can be completely moved back into a hollow tube, realizing rapid unlocking and repositioning, thereby improving the flexibility and reliability of the locking device.

[0014] Optionally, the locking block can be located outside the second electromagnet and the second electromagnet does not extend beyond a boundary line between adjacent hollow tubes.

[0015] By adopting the above technical solution, the wall panels and floor panels can be disassembled and assembled along the radial direction of the hollow tube, thereby improving the convenience and reliability of assembly.

[0017] By adopting the above technical solution, the decorative panel can be easily installed and disassembled, which is convenient for later maintenance and replacement, and improves the flexibility and maintainability of the decorative surface.

[0018] Optionally, the second magnetic body protrudes from the surface of the decorative panel, the second magnetic body can be inserted into the hollow tube and magnetically connected to the second permanent magnet, and a decorative panel is arranged with at least two second magnetic bodies in different positions.

[0021] By adopting the above technical solution, the floor can be quickly installed and disassembled, making it easy to maintain and replace.

[0022] Optionally, the third magnetic body protrudes from the surface of the floor, the third magnetic body can be inserted into the hollow tube and magnetically connected to the second permanent magnet, and the lower surface of the floor abuts against the upper surface of the floor slab.

[0023] By adopting the above technical solution, a stable connection is formed between the floor and the floor slab, while ensuring that the lower surface of the floor is in close contact with the upper surface of the floor slab, thereby enhancing the installation stability and convenience of the floor.

[0024] Optionally, the hollow tube can be ventilated or drained.

[0025] By adopting the above technical solution, hollow tubes can not only be used for pipelines, but also for ventilation or drainage, which improves the versatility of hollow tubes, facilitates the integration and management of internal building systems, simplifies the building structure and improves the overall functionality and convenience.

[0035] The following will be combined with the attached Figure 1-5, the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0036] The industrialized building based on the DFMA design method provided in the embodiment of this application is referred to Figure 1 and Figure 2 , including floor 10, wall panel 20 and hollow tube 30 arranged in floor 10 and wall panel 20, pipeline can be run in hollow tube 30, end of hollow tube 30 extends to the side or side edge of floor 10 and wall panel 20 and its end is perpendicular to the side or side edge of floor 10 and wall panel 20. A locking device 40 is arranged between the ends of adjacent hollow tubes 30, and the locking device 40 includes a sliding locking tube 41 and a magnetic control component, the sliding locking tube 41 is slidably connected to the inner wall of the hollow tube 30, the magnetic control component can control the sliding locking tube 41 to move between adjacent hollow tubes 30 so as to connect and lock adjacent hollow tubes 30 by using the sliding locking tube 41, and the magnetic control component can control the sliding locking tube 41 to completely move into a hollow tube 30 so that floor 10 and wall panel 20 can move in a direction perpendicular to the axis of the hollow tube 30. Through the above solution, the complex node connection problem in the assembly process of traditional industrialized buildings was effectively solved, the construction speed and safety were improved, and the effect of increasing construction speed and reducing labor costs was achieved.

[0037] Specifically, the rest of the floor slab 10 and the wall panel 20 except the hollow tube 30 can be a steel bar and concrete structure, and an insulation layer can be integrated inside to enhance the structural functionality. The floor slab 10 and the wall panel 20 can be prefabricated in the factory through DFMA. The floor slab 10 and the wall panel 20 both adopt a modular design concept, which can be quickly assembled, and the characteristics of various manufacturing processes are fully considered during the manufacturing process, and the advantages of precast concrete and steel structures are incorporated into the design.

[0038] Among them, when adjacent floor slabs 10 are assembled, the locking device 40 in the present application alone cannot meet the vertical bearing capacity requirements between the adjacent floor slabs 10. At this time, the lower surface of the floor slab 10 is generally connected to a steel frame, and the steel frame is combined with the floor slab 10 to enhance the vertical bearing capacity of the floor slab 10.

[0039] In addition, the wall panel 20 in the present application mainly acts as a non-load-bearing wall, used to divide the indoor space; when the indoor space needs to be redivided, the locking device 40 of the present application can realize the rapid disassembly and assembly between the wall panel 20 and the floor slab 10, as well as the adjacent wall panels 20, and the disassembly and assembly is non-destructive, thereby improving the recycling rate and reducing the cost of building manufacturing and construction assembly.

[0040] Specifically, the hollow tube 30 can be made of high-strength aluminum alloy material or high-strength fiberglass material. The high-strength aluminum alloy material has the characteristics of high strength and light weight, and is suitable for the floor 10 with many internal pipelines; the high-strength fiberglass material has the characteristics of good corrosion resistance and fire resistance, and is suitable for the wall panel 20. The hollow tube 30 is manufactured by seamless welding technology to ensure its sealing and structural strength.

[0041] Among them, the layout of the hollow tube 30 in the floor 10 or the wall panel 20 is generally parallel to the board surface of the floor 10 or the wall panel 20, so that the self-weight of the floor 10 or the wall panel 20 is lighter, the overall weight reduction can reach 30%, and the floor 10 can withstand a load of 10KN / m2.

[0042] At the same time, the hollow tubes 30 in a floor 10 or a wall panel 20 are distributed vertically and horizontally and are interconnected, and pipelines can be routed inside the hollow tube 30. Specifically, the pipelines can be electromechanical pipelines, water and electricity pipelines, etc. The pipelines can be pre-installed in the hollow tube 30, and interfaces are reserved at the mouth of the hollow tube 30. Adjacent pipelines can be connected through hose connectors. After the pipelines are connected, adjacent wall panels 20, adjacent floor slabs 10, or wall panels 20 and floor slabs 10 are assembled, and the pipelines can be pre-buried in the hollow tube 30, and the hollow tube 30 can be used to integrate and layout the pipelines. In addition, the interfaces at other positions of the mouth of the hollow tube 30 can be used to connect equipment to achieve the supply of water and electricity to the equipment.

[0043] Reference Figure 2 and Figure 3 Specifically, the sliding locking tube 41 is a second permanent magnet, which can be made of neodymium iron boron and can move under the action of a magnetic field. The magnetic control component includes a first permanent magnet 42 fixed to the inner wall of a hollow tube 30 and a first electromagnet 43 fixed to the inner wall of an adjacent hollow tube 30. The first permanent magnet 42 can be made of samarium cobalt or neodymium iron boron material, has a strong magnetic force, and can form a stable magnetic connection with the sliding locking tube 41, so that the sliding locking tube 41 can be completely placed in a hollow tube 30.

[0044] The first electromagnet 43 is connected to an external power source through a wire running inside the hollow tube 30. When the first electromagnet 43 is energized, the magnetic field intensity generated is greater than the magnetic force between the first permanent magnet 42 and the sliding locking tube 41, thereby moving the sliding locking tube 41 between adjacent hollow tubes 30. A first locking piece 50 is provided between the sliding locking tube 41 and the adjacent hollow tubes 30, and the connection and locking of adjacent hollow tubes 30 are achieved by the first locking piece 50.

[0045] Specifically, a locking groove 31 is opened on the inner wall of the hollow tube 30, and the first locking member 50 between the sliding locking tube 41 and the adjacent hollow tube 30 includes a locking block 51 and a locking elastic member 52. The locking block 51 is arranged around the outer periphery of the sliding locking tube 41 and is radially slidably connected to the outer wall of the sliding locking tube 41. The locking block 51 can be completely placed in the outer wall of the sliding locking tube 41 to achieve unlocking; the locking elastic member 52 can be a spring product, one end of the locking elastic member 52 is connected to the locking block 51, and the other end is connected to the side wall of the sliding locking tube 41. The locking elastic member 52 has elastic potential energy to push the locking block 51 toward the locking groove 31, so that the locking block 51 can be clamped between the locking groove 31 and the sliding locking tube 41, and the locking block 51 is used to limit the axial displacement of the adjacent hollow tubes 30.

[0046] Among them, an unlocking piece for releasing the lock of the locking block 51 is provided on the inner side of the adjacent hollow tube 30. Specifically, the locking block 51 is a first magnetic body, and the unlocking piece is a second electromagnet 60. The second electromagnet 60 is connected to the first electromagnet 43 through a connecting part 61, so that the cross-section of the second electromagnet 60, the connecting part 61 and the first electromagnet 43 is L-shaped, and a plug-in groove for the sliding locking tube 41 to pass through is formed between the outer wall of the second electromagnet 60 and the inner wall of the hollow tube 30. When the adjacent hollow tube 30 is in a locked state, the sliding locking tube 41 is plugged into the plug-in groove.

[0047] When the second electromagnet 60 is powered on, the magnetic field generated attracts the locking block 51 toward the second electromagnet 60, so that the locking block 51 moves out of the locking groove 31 and releases the locked state. At this time, the first electromagnet 43 is powered off, and the magnetic force between the first permanent magnet 42 and the sliding locking tube 41 is greater than the magnetic force between the sliding locking tube 41 and the second electromagnet 60. The sliding locking tube 41 can be completely moved back into a hollow tube 30 to unlock the adjacent hollow tube 30. Preferably, the second electromagnet 60 does not extend beyond the boundary line of the adjacent hollow tubes 30, so that the floor slab 10 and the wall panel 20 can move radially along the hollow tube 30, thereby improving the convenience of disassembly and assembly.

[0048] The above-mentioned locking device 40 solution only needs to energize the first electromagnet 43 or the second electromagnet 60 when locking or unlocking. For example, when locking, the first electromagnet 43 is energized, and the first electromagnet 43 magnetically attracts the sliding locking tube 41 to abut against the first electromagnet 43, and the locking block 51 is clamped in the locking groove 31. After locking, the first electromagnet 43 is de-energized, and the locking block 51 and the magnetic force of the first permanent magnet 42 on the second permanent magnet can improve the locking stability of the sliding locking tube 41 between adjacent hollow tubes 30. The same is true for unlocking.

[0049] In addition, the magnitude of the magnetic attraction force between the first electromagnet 43, the second electromagnet 60, the second permanent magnet, the first permanent magnet 42 and the locking block 51 can be determined by adjusting the position between the two, so as to determine whether the locking device 40 can move, lock or unlock along the preset direction by turning the first electromagnet 43 and the second electromagnet 60 on and off.

[0050] Reference Figure 1 and Figure 4 In one embodiment, a decorative panel 70 is detachably mounted on the surface of the wall panel 20. A second magnetic body 71 is disposed on the inner side of the decorative panel 70, which can form a stable magnetic connection with the sliding locking tube 41. Therefore, for the wall panel 20 with the tube mouth of the hollow tube 30 exposed, the decorative panel 70 can be used to cover the wall panel 20, and the decorative panel 70 can be detachably mounted on the wall panel 20 without damage. When the indoor personnel need to perform DIY design, the decorative panel 70 can be quickly replaced to enhance the personalized design of the interior.

[0051] Preferably, the second magnetic body 71 protrudes from the surface of the decorative panel 70, and the second magnetic body 71 can be inserted into the hollow tube 30 and magnetically connected to the sliding locking tube 41. At this time, the inner side surface of the decorative panel 70 abuts against the wall surface of the wall panel 20. Among them, a decorative panel 70 is arranged with at least two second magnetic bodies 71 at different positions, so as to use the second magnetic body 71 to position and install the decorative panel 70. Specifically, the shape of the second magnetic body 71 can be round or square. In this embodiment, two decorative panels 70 can be installed on a wall panel 20, and two adjacent decorative panels 70 can share a hollow tube 30 for connection. In other embodiments, multiple decorative panels 70 can also be installed on a wall panel 20, or one decorative panel 70 can be installed on multiple wall panels 20, which can be selected according to needs.

[0052] Reference Figure 1 and Figure 5 In one embodiment, a floor 80 is detachably mounted on the surface of the floor 10, and a third magnetic body 81 is disposed on the lower surface of the floor 80, and the third magnetic body 81 can be magnetically connected to the sliding locking tube 41. Preferably, the third magnetic body 81 protrudes from the surface of the floor 80, and the third magnetic body 81 can be penetrated through the hollow tube 30 and magnetically connected to the sliding locking tube 41, and the lower surface of the floor 80 abuts against the upper surface of the floor 10. Similarly, the detachable connection between the floor 80 and the floor 10 facilitates the subsequent rapid replacement of the floor 80, and further simplifies the indoor assembly process.

[0053] Specifically, the hollow tube 30 can be ventilated or drained, which enhances the versatility of the hollow tube 30 and provides more possibilities for the use of the hollow tube 30. Ventilation here means that the air in the hollow tube 30 can circulate in the hollow tube 30, so that the heat can be kept balanced in the hollow tube 30, and the service life of the pipeline in the hollow tube 30 is extended.

[0054] The drainage here refers to the water stains leaking from the gaps in the floor 80. These water stains can enter the hollow tube 30 through the pipe opening of the hollow tube 30 and be discharged from the hollow tube 30 (additional drainage ports are provided at other locations). In addition, in order to ensure the sealing effect between adjacent hollow tubes 30, sealing pads can be provided at the pipe openings of adjacent hollow tubes 30. When adjacent hollow tubes 30 are connected, the sealing pads are used to perform a sealing effect.

[0055] The implementation principle of this embodiment is: by adopting the modular design concept, the house is decomposed into reusable standardized modules, and the characteristics and advantages of the manufacturing process are fully considered in the design process to achieve a simplified assembly process and a reliable connection method, thereby improving the safety, maintainability and construction speed of the building structure. Through the seamless connection between design and manufacturing, the workload of on-site construction is reduced, and the safety risks of industrialized building nodes are effectively reduced. The magnetic control assembly combined with the locking device 40 realizes the efficient connection and locking function of the hollow tube 30, and is easy to disassemble and maintain, further improving the design level and construction efficiency of industrialized buildings. Relying on the DFMA design concept and the application of TRIZ innovation theory, the existing technology has been significantly improved and the technological progress of the construction industry has been promoted.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
