Description

Technical Field

[0001] This application relates to the field of modular building technology, and in particular to a method for manufacturing a building product system with separate structural and functional modules. Background Technology

[0002] Currently, in the field of housing construction, the main building forms include cast-in-place structures, prefabricated buildings, and modular buildings.

[0003] Cast-in-place structures form a load-bearing system by tying steel bars, erecting formwork, and pouring concrete on-site. While they offer strong structural integrity and seismic stability, they also suffer from drawbacks such as extensive on-site wet work, long construction periods, and significant susceptibility to weather conditions. More importantly, their structure and function are highly intertwined, making it difficult to flexibly adjust interior spaces. Subsequent renovations often require the demolition and alteration of load-bearing structures, which is risky and costly.

[0004] Prefabricated buildings improve construction speed by using prefabricated components in factories and assembling them on site. However, component assembly still needs to be carried out simultaneously with functional pipelines, making coordination of cross-operations difficult. The structure and function remain bound together, resulting in poor component versatility, insufficient spatial flexibility, and frequent structural damage during later operation and maintenance.

[0005] Modular buildings complete the structure, decoration, and pipeline integration of spatial modules in the factory. Although the integration level is high, the structure and function are not truly separated. Space adjustments still require the dismantling and modification of the entire module, and the reuse rate of modules across projects is low, with high initial investment and transportation costs.

[0006] In summary, existing building systems generally suffer from the common problem of deep integration between structure and function, resulting in rigid spatial layouts, difficulty in renovation, and low resource recycling rates.

[0007] Some buildings have attempted to separate structural and functional modules, but these adjustments are typically made only within small functional spaces formed by beams and columns. They fail to adequately consider the combination and variability of large, single-level spaces, or still require the addition of beam and column structures within the structural space. This results in spatial adjustments still necessitating the demolition and alteration of the entire module, low module reuse rates across projects, and high initial investment and transportation costs.

[0008] Alternatively, a hanging structure can be used. However, since the modules are hung on the core structure using hooks, the functional space cannot be flexible and varied. Furthermore, the hanging fixed structure is difficult to implement and is not suitable for high-rise buildings.

[0009] In addition, in the traditional model, housing is a fixed structure that cannot be moved or relocated, which, from a technical point of view, also limits users' need for cross-regional housing mobility. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings and provide a building product system and manufacturing method that separates the structure and functional modules.

[0011] To address the aforementioned technical problems, this application provides a building product system that separates structural and functional modules, employing the following technical solution: A building product system that separates structural and functional modules includes: The structural base includes vertical support structures and transverse large-span floor slabs; it is used for the building's load-bearing and lateral force resistance, and internally forms multiple large-span interior spaces without beams or columns, divided according to residential or activity functions; Multiple indoor functional units are located within the indoor space and detachably connected to the structural base, for the purpose of realizing living or activity functions; one indoor functional unit is provided within each indoor space to realize the corresponding function; the indoor functional units do not participate in the building's load-bearing capacity; A standardized interface is provided between the structural base and the indoor functional unit to realize the structural, piping and circuit connection between the indoor functional unit and the structural base.

[0012] Since each interior space forms an independent, large-span, column-free space, the interior shear wall design can be eliminated, and the exterior lighting surfaces are equipped with frame beams and columns, creating unlimited customizable spaces and facilitating living activities.

[0013] Preferably, large-span floor slabs are made of composite floor slabs or steel structure floor slabs, but concrete floor slabs can also be selected.

[0014] By adopting the above technical solution, the building is divided into a structural base that bears the load and resists lateral forces and an indoor functional unit that provides living functions. The two are decoupled by a standardized interface, which fundamentally solves the technical problems of rigid spatial layout, difficulty in renovation and low resource recycling rate caused by the high degree of binding between structure and function in the existing technology.

[0015] Optionally, the structural base includes a vertical core tube, an outer perimeter structure, and a horizontal large-span floor slab; the core tube adopts a shear wall structure; the outer perimeter structure is connected to the outside of the core tube and adopts a frame, shear wall, or mega-frame structure; the large-span floor slab is horizontally connected between the core tube and the outer perimeter structure to form the interior space.

[0016] Specifically, the large-span, beam-free, and column-free interior space formed within the structural foundation provides exceptional flexibility for the arrangement of interior functional units, freeing the building from the constraints of densely packed vertical components found in traditional cast-in-place or prefabricated structures. Since the interior functional units do not bear load and are detachably connected via standardized interfaces, future renovations only require module replacement or recombination, eliminating the need to alter the load-bearing structure. This significantly reduces construction risks and renovation costs, and avoids the generation of construction waste. Finally, this decoupled system facilitates a new asset model combining structural foundation leasing with module relocation, enabling users to move their interior functional units across regions, transforming immovable housing assets into movable personal assets and reducing long-term occupancy costs.

[0017] In the above technical solution, the core tube includes a space for centrally managing the vertical transportation of elevators, stairs, vestibule spaces, and various electrical, water, and ventilation main pipelines.

[0018] The structure of the core tube is not limited to a specific implementation form; it can be prefabricated, cast-in-place, modular, or a combination of multiple methods.

[0019] In the above technical solutions, the external structure adopts at least one of the following forms: frame, shear wall, frame-shear wall, or mega-frame structure.

[0020] The outer structure is connected and fixed to the core tube from the outside, together forming the supporting framework of the entire building.

[0021] The core of this invention lies in creating a beam-free and column-free large-scale interior space through a core tube, an outer structure, and large-span floor slabs. It can be applied to high-rise and super high-rise buildings.

[0022] By adopting the above technical solutions, the external structure can work together with the core tube to form the supporting framework of the entire building. Using large-span floor slabs can significantly reduce the number of supporting columns or beams in the interior space, making the interior space more spacious and reducing the obstruction of supporting columns or beams to the installation of interior functional units. This allows for the free splicing and flexible layout of interior functional units of different specifications, providing a solid structural foundation for the on-demand conversion of various apartment types.

[0023] Optionally, the core tube, the outer structure, and the large-span floor slab are connected by one of the following methods: bolt connection, welding, grouting sleeve connection, or lap anchoring connection.

[0024] More specifically, in the structural base, the core tube, the outer structure and the large-span floor slab can also adopt the hybrid lateral force resisting structural system of Chinese patent CN120906277B, which combines the lateral and vertical support systems through the connection mechanism.

[0025] By adopting the above technical solutions, these connection methods can ensure the continuity and stability of the overall stress system of the structural base, enabling precast components to achieve an overall performance close to that of cast-in-place structures. At the same time, they reduce the numerous on-site binding and formwork procedures required in traditional cast-in-place construction, shorten the construction period of the structural base, improve construction accuracy, and provide the necessary positional accuracy guarantee for precise docking between subsequent indoor functional units and the structural base through standardized interfaces.

[0026] Optionally, in the external structure, steel-concrete composite columns or (combined) shear walls can be added to the vertically supported frames, shear walls, or important load-bearing locations to strengthen the structure and achieve better seismic performance.

[0027] Optionally, the indoor functional units are installed inside the structural base by vertical hoisting or horizontal sliding.

[0028] By adopting the above technical solutions, indoor functional units can be installed in the predetermined indoor space like building blocks or drawers without damaging the structural base or other structures. This not only improves the safety of on-site operations, but also avoids the cross-interference between traditional decoration and structural construction, which can shorten the construction cycle by 30% to 40% and improve construction efficiency.

[0029] Optionally, the interior functional unit has bedroom, bathroom, or kitchen functions. The interior functional unit includes a frame and panels covering the frame. The interior functional unit integrates pipelines, doors, windows, interior decorations, and equipment for realizing the corresponding functions.

[0030] By adopting the above technical solutions, the frame structure reduces its self-weight while ensuring modular rigidity, thereby lowering the requirements for the structural foundation's load-bearing capacity and reducing transportation and hoisting costs. All components are pre-integrated within the interior functional units, allowing for centralized prefabrication and quality inspection in the factory, avoiding common quality problems such as pipe leaks and power outages caused by improper manual operation during on-site decoration. This highly integrated design makes the functional parts of the building a standard industrial product that can be mass-produced and quickly replaced.

[0031] Optionally, the exterior of the indoor functional unit is provided with a protective structure consisting of at least a fireproof layer, a waterproof layer, a sound insulation layer, and a thermal insulation layer.

[0032] By adopting the above technical solutions, the protective structure constructs an independent physical protective layer for the indoor functional units, enabling them not only to meet the comfort requirements of living but also to possess independent safety assurance capabilities. Specifically, the fireproof layer can prevent the spread of fire to the structural base or other indoor functional units in the event of a fire in a single indoor functional unit, thereby improving the building's passive fire safety level. The waterproof layer can prevent water from continuing to seep into other structural bases or other indoor functional units when a leak occurs in a single indoor functional unit, improving the waterproof performance of the indoor functional units. The sound insulation layer and thermal insulation layer can achieve acoustic and thermal isolation between indoor functional units and between indoor functional units and the structural base, improving the sound insulation and thermal insulation performance of the indoor functional units.

[0033] Optionally, the standardized interface includes a structural interface, a pipeline interface, and a circuit interface with quick assembly and disassembly functions.

[0034] By adopting the above technical solution, during the installation of indoor functional units, the structural interfaces achieve reliable and robust mechanical connections, while the pipe and electrical interfaces enable rapid energy and signal conduction. This standardized design not only improves the operational efficiency of indoor functional units during the installation phase but also enhances the convenience of subsequent operation and maintenance. When a pipeline in a single indoor functional unit malfunctions or the equipment becomes obsolete, the user only needs to disconnect the interface to disassemble, repair, or upgrade the indoor functional unit without the need for destructive removal of the structural base.

[0035] Optionally, the structural interface includes a positioning guide, a mating structure, and a detachable connector; the positioning guide is disposed on the structural base; the mating structure is disposed on the indoor functional unit and is used to mate with the positioning guide; the detachable connector is used to connect the structural base and the indoor functional unit. Optionally, a shock-absorbing pad such as rubber is provided at the interface to reduce vibration transmission.

[0036] By adopting the above technical solution, the positioning guide and the mating structure play an auxiliary guiding role in the installation of the indoor functional units, ensuring that the heavy indoor functional units can automatically calibrate and align their positions during hoisting, reducing the difficulty of alignment and safety risks. The detachable connectors can firmly connect the structural base to the indoor functional units after they are installed in place. This combined design ensures the installation accuracy and strength of the indoor functional units, and because the detachable connectors improve the ease of connection during the disassembly or replacement of functional modules, the indoor functional units can still be reliably connected to the structural base after several reuses, extending the recycling life of the indoor functional units.

[0037] Optionally, the pipeline interface includes a quick-connect female connector, a quick-connect male connector, and a switch valve; a vertical pipe well is provided on the structural base, the quick-connect female connector is located in the indoor space, and an external water pipe or gas pipe is connected to the quick-connect female connector through the vertical pipe well; the quick-connect male connector is connected to the water pipe or gas pipe inside the indoor functional unit and is used for detachable connection with the quick-connect female connector; the switch valve is located between the external water pipe or gas pipe and the quick-connect female connector.

[0038] By adopting the above technical solutions, vertical pipe shafts achieve centralized energy transmission, distribution, and management, simplifying the amount of horizontal piping required in indoor spaces. Quick-connect couplings are leak-proof, detachment-proof, and allow for immediate connection, eliminating the need for complex on-site welding or heat fusion processes for water and gas pipe connections. The installation of on / off valves ensures that when replacing or repairing a single module, the water and gas supply systems of the entire floor or even the entire building do not need to be shut down, enabling point-to-point operation and maintenance management and enhancing the convenience of maintenance.

[0039] Optionally, the circuit interface includes a quick-connect socket and a quick-connect plug; a vertical electrical well is provided on the structural base, the quick-connect socket is located in the indoor space, and external signal lines or power transmission lines are electrically connected to the quick-connect socket through the vertical electrical well; the quick-connect plug is electrically connected to the signal lines and power transmission lines inside the indoor functional unit and is used for detachable connection with the quick-connect socket.

[0040] By adopting the above technical solutions, the vertical electrical shaft centralizes external signal lines and power transmission lines, reducing external interference to both high-voltage and low-voltage circuits and facilitating unified maintenance. The combination of quick-connect plugs and sockets allows electrical equipment, smart home systems, and network signals within indoor functional units to quickly connect to the building's backbone network, supporting plug-and-play functionality for various signal types. This, in turn, reduces labor costs for electrical installation and improves construction efficiency.

[0041] Based on the above product system, this invention also provides a construction method covering the key steps of construction, installation, modification, and relocation of this building product system with separated structural and functional modules. Specifically: A building construction method that separates structural and functional modules includes the following steps: S1: Construct a structural base, including constructing a vertical support structure and a transverse large-span floor slab, so that the structural base has the ability to bear load and resist lateral forces, and forms a multi-layered, beam-free, column-free, large-span indoor space inside; S2: A standardized interface is provided on the structural base, the standardized interface including a structural interface, a pipeline interface and a circuit interface; S3: Prefabricated interior functional unit, which integrates pipelines, doors, windows, interior decoration and equipment to realize the corresponding living functions. The interior functional unit does not participate in the building's load-bearing capacity. S4: The indoor functional unit is detachably installed in the indoor space through the standardized interface, so as to realize the structural connection, pipeline connection and circuit connection between the indoor functional unit and the structural base.

[0042] Furthermore, step S1 specifically includes: Construct a vertical core tube using a shear wall structure; An outer perimeter structure is connected to the outside of the core tube, and the outer perimeter structure is a frame, shear wall or mega-frame structure. A large-span floor slab is connected between the core tube and the outer structure to form the beam-free and column-free interior space.

[0043] Furthermore, the core tube, the outer structure, and the large-span floor slab are connected by at least one of the following methods: bolt connection, welding, grouting sleeve connection, or lap anchoring connection.

[0044] Furthermore, the installation described in step S4 includes at least one of vertical hoisting or horizontal sliding.

[0045] Furthermore, the structural interface setting in step S2 includes: setting a positioning guide on the structural base; setting a mating structure on the indoor functional unit that cooperates with the positioning guide; and setting a detachable connector for connecting the structural base and the indoor functional unit.

[0046] A method for transforming architectural space, based on any of the architectural product systems described above, includes the following steps: Disconnect the standardized interface between the indoor functional unit to be modified and the structural base. The standardized interface includes a structural interface, a pipeline interface, and a circuit interface. Remove the indoor functional unit to be modified from the indoor space of the structural base; The new interior functional units are moved into the interior space; The new indoor functional unit is connected to the structural base through the standardized interface, thereby achieving structural fixation, pipeline connection, and circuit connection.

[0047] Furthermore, disconnecting the pipeline interface includes closing the switch valve at the pipeline interface to cut off the connection between the external water pipe or gas pipe and the indoor functional unit to be modified.

[0048] A method for relocating buildings across regions, based on any of the building product systems described above, includes the following steps: At the structural base of the first location, disconnect the standardized interfaces between all user indoor functional units and the structural base; The indoor functional unit was removed from the structural base at the first location and transported to the second location; At the second location, the indoor functional unit is installed in the indoor space of the local structural base via a standardized interface.

[0049] Furthermore, the transportation includes at least one of road transportation, rail transportation, or water transportation.

[0050] A building operation and maintenance method, based on any of the building product systems described above, includes the following steps: Monitor the operational status of each indoor functional unit; When a single indoor functional unit fails or the equipment ages, only the standardized interface between the indoor functional unit and the structural base is disconnected. The indoor functional unit will be dismantled for inspection or replacement. The repaired or new indoor functional units can be reinstalled through the standardized interface without requiring destructive construction of the structural base.

[0051] In summary, this application includes the following beneficial technical effects: 1. In existing structural systems, the large number of vertical structural components and the small floor span limit the spatial layout and make it impossible to flexibly adjust according to usage requirements. The present invention can solve the problem of insufficient spatial flexibility.

[0052] The beam-free and column-free interior space formed inside the structural base provides extremely high flexibility for the arrangement of interior functional units, so that the building structure is no longer restricted by the dense vertical components in traditional cast-in-place or prefabricated structures.

[0053] 2. The indoor functional units do not participate in load-bearing and are detachable through standardized interfaces, so that later renovations only require the replacement or recombination of modules without touching the load-bearing structure, which greatly reduces construction risks and renovation costs and avoids the generation of construction waste.

[0054] 3. Through the separation of structure and function and the flexible combination in the beam-free and column-free interior space, it is safe and reliable compared to the attached building and is very suitable for high-rise and super high-rise buildings.

[0055] 4. Traditional building owners' properties cannot be moved. This invention adopts a decoupled system combining structural support and functional modules, enabling users to move their indoor functional units across regions over long distances. This transforms immovable housing assets into mobile personal spaces, reducing long-term living costs and meeting users' needs for short-term residence and cross-regional mobility. It also establishes a rapid technological foundation for a new asset model based on structural foundation leasing combined with modular relocation.

[0056] 5. Without damaging the structural base or other structures, indoor functional units can be installed in the predetermined indoor space like building blocks or drawers. This not only improves the safety of on-site operations, but also avoids the cross-interference between traditional decoration and structural construction, which can shorten the construction cycle by 30% to 40% and improve construction efficiency.

[0057] 6. During the installation of indoor functional units, the structural interfaces achieve reliable and robust mechanical connections, while the pipe and electrical interfaces enable rapid energy and signal transmission. This standardized design not only improves the operational efficiency of indoor functional units during installation but also enhances the convenience of subsequent operation and maintenance. When a pipeline in a single indoor functional unit fails or the equipment becomes obsolete, the user can simply disconnect the interface to disassemble, repair, or upgrade the unit without the need for destructive removal of the structural base.

[0066] The following combination Figures 1-7This application will be described in further detail.

[0067] Example 1 This application discloses a building product system that separates structural and functional modules.

[0068] Reference Figure 1 and Figure 2 In this embodiment, the building product system includes a structural base 1, multiple indoor functional units 2, and standardized interfaces.

[0069] The structural base 1 serves as the building's load-bearing and lateral force resisting element, and internally forms multiple beam-free and column-free interior spaces 10 divided according to living functions. Interior functional units 2 are located within the interior spaces 10 and are detachably connected to the structural base 1, serving as living spaces; each interior space 10 contains one interior functional unit 2 fulfilling its corresponding function. The interior functional units 2 do not participate in the building's load-bearing; standardized interfaces are located between the structural base 1 and the interior functional units 2, used for structural, piping, and electrical connections between the interior functional units 2 and the structural base 1.

[0070] Specifically, the interior space 10 can be divided into bedrooms, kitchens, bathrooms, etc., based on living functions. The specific types and quantities can be set according to customer needs. The statement that the interior functional unit 2 does not participate in the building's load-bearing capacity means that the interior functional unit 2 is not designed for load-bearing purposes, rather than restricting it from participating in the load-bearing capacity of the building product system.

[0071] In this way, the building is divided into a structural base 1 that bears the load and resists lateral forces and an indoor functional unit 2 that provides living functions. The two are decoupled by a standardized interface, which fundamentally solves the technical problems of rigid spatial layout, difficult renovation and low resource recycling rate caused by the high binding of structure and function in the existing technology.

[0072] Specifically, the beam-free and column-free interior space 10 formed within the structural base 1 provides extremely high flexibility for the arrangement of interior functional units 2, freeing the building from the constraints of densely packed vertical components found in traditional cast-in-place or prefabricated structures. Interior functional units 2 do not participate in load-bearing and are detachably connected via standardized interfaces, allowing for later renovations that only require module replacement or recombination without affecting the load-bearing structure. This significantly reduces construction risks and renovation costs, and avoids the generation of construction waste. Finally, this decoupled system facilitates a new asset model based on leasing the structural base 1 and module relocation, enabling users to move their interior functional units 2 across regions, transforming immovable housing assets into movable personal assets and reducing long-term living costs for users.

[0073] Reference Figure 1 , Figure 2 and Figure 4In this embodiment, the structural base 1 includes a core tube 11, an outer structure 12, and a large-span floor slab 13. The core tube 11 adopts a shear wall structure. Shear walls are generally made of reinforced concrete and have high lateral stiffness, effectively resisting horizontal loads such as wind and seismic forces. In other embodiments, steel plate shear walls can be used instead of reinforced concrete shear walls, as steel plate shear walls have better ductility and energy dissipation capacity. Alternatively, a combined shear wall system combining shear walls 121 and beams 122 can be used to provide better load-bearing capacity.

[0074] The outer structure 12 connects to the outside of the core tube 11 and can be a frame, shear wall, or mega-frame structure. If a frame structure is used, it typically consists of steel beams and columns connected by welding or bolts, offering good spatial openness and flexibility. If a shear wall structure is used, it is similar to the shear wall 121 of the core tube 11, providing greater lateral force resistance through its connection with beams 122. A mega-frame structure consists of large frame members, capable of withstanding even greater loads.

[0075] The large-span floor slab 13 connects the core tube 11 and the outer structure 12 to form a beam-free and column-free interior space 10. The large-span floor slab 13 can be a prestressed concrete floor slab, which can improve the load-bearing capacity and crack resistance of the floor slab by applying prestress; or it can be a steel-concrete composite floor slab, which combines the advantages of steel and concrete and has high strength and stiffness.

[0076] The combination logic of the core tube 11, the outer structure 12, and the large-span floor slab 13 is as follows: the core tube 11 serves as the core support and pipeline channel of the building, centrally responsible for the vertical transportation of elevators, staircases, and various main pipelines; the outer structure 12, together with the core tube 11, forms the supporting skeleton of the entire building, bearing the vertical load and part of the horizontal load; the large-span floor slab 13 forms a beam-free and column-free interior space 10 between the core tube 11 and the outer structure 12, providing flexible space for the installation of interior functional units 2. This combination ensures that the structural base 1 has sufficient load-bearing capacity and lateral force resistance, while also facilitating the arrangement of interior functional units 2. This allows for the free splicing and flexible layout of interior functional units 2 of different specifications, providing a solid structural foundation for the on-demand conversion of various apartment types.

[0077] The core tube 11, the outer structure 12, and the large-span floor slab 13 are connected using one of the following methods: bolted connection, welding, grouting sleeve connection, or lap anchoring connection. Bolted connection involves pre-drilling holes in the two connected components and then tightening them together with bolts; this method facilitates construction and disassembly. Welding connects the two components by melting the connecting parts at high temperature, resulting in high connection strength. Grouting sleeve connection involves injecting high-strength grout into the sleeve to connect the reinforcing bars of the two components. Lap anchoring connection achieves the connection between the components through the lapping and anchoring of the reinforcing bars.

[0078] These connection methods ensure the continuity and stability of the overall load-bearing system of the structural base 1, enabling precast components to achieve an overall performance close to that of cast-in-place structures. At the same time, they reduce the numerous on-site binding and formwork procedures required in traditional cast-in-place construction, shortening the construction period of the structural base 1 and improving construction accuracy.

[0079] Preferably, the indoor functional unit 2 is installed inside the structural base 1 by vertical hoisting or horizontal sliding. Vertical hoisting can be achieved by using a crane to vertically lift the indoor functional unit 2 to a predetermined position; horizontal sliding can be achieved by using devices such as rails and pulleys to horizontally move the indoor functional unit 2 to the indoor space 10.

[0080] In this way, without damaging the structural base 1 or other structures, the interior functional units 2 can be installed in the predetermined interior space 10 like building blocks or drawers. This not only improves the safety of on-site operations, but also avoids the cross-interference between traditional decoration and structural construction, which can shorten the construction cycle by 30% to 40% and improve construction efficiency.

[0081] Reference Figure 1 and Figure 2 In this embodiment, the indoor functional unit 2 has the functions of a bedroom, bathroom, or kitchen. The indoor functional unit 2 includes a frame 21 and a panel 22 covering the outside of the frame 21. The frame 21 can be a light steel keel structure, which is made of thin-walled steel and has the advantages of light weight, high strength, and easy installation; or it can be an aluminum alloy frame 21. The panel 22 can be a fireproof board, moisture-proof board, etc., which covers the outside of the frame 21 and serves a protective and decorative purpose.

[0082] The interior functional unit 2 integrates pipelines, doors and windows, interior decorations and equipment to achieve the corresponding functions. For example, in the bedroom interior functional unit 2, lighting circuits, air conditioning pipelines, beds, wardrobes and other equipment are integrated; in the bathroom interior functional unit 2, water pipes, drainage pipes, toilets, shower heads and other equipment are integrated; in the kitchen interior functional unit 2, gas pipelines, water pipes, stoves, range hoods and other equipment are integrated.

[0083] This design of interior functional unit 2 reduces its weight while maintaining its rigidity, thereby lowering the load-bearing requirements of the structural foundation 1 and reducing transportation and hoisting costs. All pipelines and equipment are pre-integrated within interior functional unit 2, allowing for centralized prefabrication and quality inspection in the factory. This avoids common quality problems such as pipe leaks and power outages caused by improper manual operation during on-site decoration. This highly integrated design makes the building's functional components standard industrial products that can be mass-produced and quickly replaced.

[0084] The exterior of indoor functional unit 2 is equipped with a protective structure consisting of at least a fireproof layer, a waterproof layer, a sound insulation layer, and a thermal insulation layer. The fireproof layer can be made of fire-resistant rock wool board, which has excellent fire resistance and can prevent the spread of fire. The waterproof layer can be made of waterproof coating or waterproof membrane to prevent water leakage. The sound insulation layer can be made of sound-absorbing cotton, which can effectively reduce sound transmission. The thermal insulation layer can be made of polystyrene foam board, which has good thermal insulation properties.

[0085] In this way, the protective structure creates an independent physical protective layer for indoor functional unit 2, enabling it to not only meet the comfort requirements of living but also possess independent safety capabilities. The fire-resistant layer can prevent the spread of fire to the structural base 1 or other indoor functional units 2 in the event of a fire in a single indoor functional unit 2, thus improving the building's passive fire safety level. The waterproof layer can prevent water leakage from a single indoor functional unit 2 from continuing to seep into other structural base 1 or other indoor functional units 2, improving the waterproof performance of indoor functional unit 2. The sound insulation and thermal insulation layers can achieve acoustic and thermal isolation between indoor functional units 2 and between indoor functional units 2 and the structural base 1, improving the sound insulation and thermal insulation performance of indoor functional units 2.

[0086] Reference Figure 3 and Figure 5 In this embodiment, the standardized interfaces include a structural interface 3 with quick-disassembly and assembly capabilities, a pipeline interface 4, and a circuit interface 5. During the installation of the indoor functional unit 2, the structural interface 3 provides a reliable and robust mechanical connection, while the pipeline interface 4 and circuit interface 5 enable rapid energy and signal transmission. This standardized design not only improves the operational efficiency of the indoor functional unit 2 during the installation phase but also enhances the convenience of subsequent operation and maintenance. When a pipeline in a single indoor functional unit 2 malfunctions or the equipment becomes obsolete, the user only needs to disconnect the interface to disassemble, repair, or upgrade the indoor functional unit 2 without the need for destructive removal of the structural base 1.

[0087] Reference Figure 4 and Figure 6In this embodiment, the structural interface 3 specifically includes a positioning guide 31, a mating structure 32, and a detachable connector 33. The positioning guide 31 can be a positioning pin, typically made of steel, and is installed on the outer structure 12 or a large-span floor slab. The mating structure 32 can be a positioning hole, set on the frame 21 of the indoor functional unit 2, and cooperates with the positioning pin to provide auxiliary guidance. The detachable connector 33 can be a bolt or a clip, which securely connects the structural base 1 and the indoor functional unit 2 together.

[0088] In this way, the cooperation between the positioning guide 31 and the mating structure 32 plays an auxiliary guiding role in the installation of the indoor functional unit 2, ensuring that the heavy indoor functional unit 2 can automatically calibrate its position and align during hoisting, reducing the difficulty of alignment and safety risks. The detachable connector 33 can firmly connect the structural base 1 and the indoor functional unit 2 after the indoor functional unit 2 is installed in place. This combination design ensures the installation accuracy and strength of the indoor functional unit 2, and because the detachable connector 33 improves the convenience of connection when disassembling or replacing the functional template, the indoor functional unit 2 can still be reliably connected to the structural base 1 after several reuses.

[0089] Reference Figure 4 and Figure 7 In this embodiment, the pipe interface 4 includes a quick-connect female connector 41, a quick-connect male connector 42, and a switching valve 43. A vertical pipe shaft 14 is provided inside the core tube 11; the quick-connect female connector 41 is fixedly installed on the outer structure 12 and located in the indoor space 10; external water pipes or gas pipes are connected to the quick-connect female connector 41 through the vertical pipe shaft 14. The quick-connect male connector 42 is fixedly connected to the frame 21 of the indoor functional unit 2, and connects to the internal water pipes or gas pipes of the indoor functional unit 2, and is used for detachable connection with the quick-connect female connector 41. The switching valve 43 is located between the external water pipe or gas pipe and the quick-connect female connector 41. The quick-connect female connector 41 and the quick-connect male connector 42 can be made of plastic or metal, and have the characteristics of being leak-proof, detachable, and plug-and-play. The switching valve 43 can be a ball valve or a gate valve, used to control the flow of water or gas.

[0090] In this way, the vertical manhole 14 enables centralized energy transmission, distribution, and management, simplifying the horizontal piping of the indoor space 10. Quick-connect fittings eliminate the need for complex on-site welding or heat fusion processes when connecting water and gas pipes. The on / off valve 43 ensures that when replacing or repairing a single module, it is not necessary to shut down the water and gas supply system of the entire floor or even the entire building, achieving point-to-point operation and maintenance management and enhancing the convenience of operation and maintenance.

[0091] Reference Figure 4 and Figure 7In this embodiment, the circuit interface 5 includes a quick-connect socket 51 and a quick-connect plug 52. A vertical electrical shaft 15 is provided on the structural base 1; the quick-connect socket 51 is fixedly installed on the peripheral structure 12 and located in the indoor space 10; external signal lines or power transmission lines are electrically connected to the quick-connect socket 51 through the vertical electrical shaft 15. The quick-connect plug 52 is fixedly connected to the frame 21 of the indoor functional unit 2, and the quick-connect plug 52 electrically connects to the signal lines and power transmission lines inside the indoor functional unit 2, and is used for detachable connection with the quick-connect socket 51. The quick-connect socket 51 and quick-connect plug 52 can adopt universal electrical or communication interface standards, supporting plug-and-play functionality for various signal types.

[0092] In this way, the vertical electrical shaft 15 centralizes external signal lines and power transmission lines, reducing external interference to both high-voltage and low-voltage circuits and facilitating unified maintenance. The combination of quick-connect plugs 52 and quick-connect sockets 51 allows electrical equipment, smart home systems, and network signals within the indoor functional unit 2 to quickly access the building's backbone network, supporting plug-and-play functionality for various signal types. This further reduces labor costs for electrical installation and improves construction efficiency.

[0093] The implementation principle of this application embodiment is as follows: the building is divided into a structural base 1 that bears the load and resists lateral forces, and an indoor functional unit 2 that provides residential functions, and the two are decoupled through a standardized interface. The indoor functional unit 2 is located in the indoor space 10 inside the structural base 1, and is detachably connected to the structural base 1 through a standardized interface. This achieves the separation of the building's load-bearing capacity and functional implementation, solving the problems of rigid spatial layout, difficult renovation, and low resource recycling rate caused by the high degree of binding between structure and function in the prior art. This is because the structural base 1 bears the load and resists lateral forces of the building, while the indoor functional unit 2 is only responsible for realizing residential functions, and the two are detachably connected through a standardized interface, allowing for flexible module replacement or reorganization in later renovations without dismantling or altering the load-bearing structure.

[0094] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
