Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to a closed construction method and building. Background Technology

[0002] my country's urban development has shifted from incremental expansion to a stage of improving the quality and efficiency of existing infrastructure. Implementing urban renewal is a crucial measure to promote high-quality urban development. A large number of urban renewal projects are concentrated in densely built-up old urban areas. These old urban areas are characterized by low-rise and multi-story buildings, generally featuring limited space, high population density, and traffic congestion. Narrow surrounding roads hinder vehicle traffic, and the close proximity of buildings, including "handshake buildings" and overhead power lines, makes it difficult to transport construction equipment or prevents its passage. On-site construction significantly occupies surrounding roads, preventing the creation of a closed working environment. Furthermore, dust and noise generated by on-site machinery affect the lives of nearby residents, leading to numerous complaints and significant social and economic impacts, becoming a major obstacle to the renovation of old buildings.

[0003] For construction projects in densely populated areas, existing construction methods typically require occupying surrounding land to set up fences and erect scaffolding for construction operations and protection. In these methods, the building structure is separated from the construction fences and protective systems. After construction is completed, temporary facilities such as fences and scaffolding need to be dismantled. The entire construction process is exposed to the urban environment, has a long construction period, involves a large amount of wet work on site, occupies a large area, and cannot form a fully enclosed three-dimensional construction site. The noise and other environmental pollution generated during the process are significant, which has a major impact on the urban landscape. Summary of the Invention

[0004] The purpose of this invention is to provide a closed construction method and building to solve at least some of the problems mentioned above.

[0005] The first aspect of this invention provides a closed construction method for functional building construction in confined spaces within high-density urban areas; the method includes: The functional building is divided into building modules and prefabricated components; The building module is located in the external area of ​​the functional building space; Prefabricated components are installed in other areas of the functional building space; wherein, a plurality of the building modules enclose the functional building space to form a closed space isolated from the external environment, or, a plurality of the building modules and a plurality of the prefabricated components are combined to enclose the functional building space to form a closed space isolated from the external environment. Construction was carried out within the enclosed space.

[0006] Furthermore, the building module is a replicable standard building structure, and several of the building modules are horizontally spliced ​​and / or stacked together by hoisting and splicing in the external area.

[0007] Furthermore, the exterior of the building module is provided with an exterior finish.

[0008] Furthermore, the prefabricated component includes a first prefabricated component, and the installation of the prefabricated component in other areas of the functional building space includes: The first prefabricated component is erected in the internal area of ​​the construction space.

[0009] Furthermore, the prefabricated component includes a second prefabricated component, and the installation of the prefabricated component in other areas of the functional building space further includes: The second prefabricated component is erected in the external area where no building modules are set up to connect the adjacent building modules; A dust-proof and noise-reducing barrier is hung on the outside of the second prefabricated component, so that the building module and the dust-proof and noise-reducing barrier together form the enclosed space.

[0010] Furthermore, the building module is located in a spacious external area; The second prefabricated component is erected in the narrow outer area.

[0011] Furthermore, the installation of prefabricated components in other areas of the functional building space includes: Following the construction sequence of from far to near and from outside to inside, the hoisting of precast components was completed layer by layer.

[0012] Furthermore, the top of the enclosed space can be in an open state, an openable / closable state, or a closed state.

[0013] Furthermore, the construction of the building module and the prefabricated components within the enclosed space includes: Construction work including wall installation, interior decoration, and electromechanical system installation is carried out within the enclosed space.

[0014] A second aspect of the present invention provides a building constructed using a closed construction method, comprising building modules and prefabricated components, wherein the building modules and prefabricated components are constructed to form the building using the closed construction method described above.

[0015] The beneficial effects of this plan are as follows: By breaking down functional buildings into modules and prefabricated components, and setting up building modules and installing prefabricated components in the external area, a closed space isolated from the outside world is formed for construction, effectively isolating the construction area and reducing the spread of environmental pollution. This construction method allows for the rapid enclosure of the proposed building along the street, achieving a rapid transformation of the urban visual image and minimizing the negative impact on the urban landscape.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "joined" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or they can refer to the internal communication of two components. For those skilled in the art, the specific meaning of the terms in this invention can be understood according to the specific circumstances.

[0020] First Embodiment See Figure 1 This embodiment discloses a closed construction method for functional buildings in confined spaces within high-density urban areas; the method includes: S11. The functional building is divided into building modules and first prefabricated components; the overall structure and function of the functional building are decomposed into several building modules and prefabricated components. Among them, the building modules are replicable standard building structures, and several building modules are horizontally spliced ​​and / or stacked and spliced ​​in the external area by hoisting.

[0021] By designing the building modules as replicable, standardized building structures, factory-produced and mass-produced modules were achieved, significantly improving manufacturing efficiency and quality consistency while reducing production costs. Simultaneously, the standardized design simplifies and enhances on-site installation. Furthermore, the use of hoisting methods for horizontal splicing and / or stacking greatly shortens on-site construction time and reduces the impact on the surrounding environment, making it particularly suitable for the rapid construction needs of confined spaces in high-density urban areas. This efficient assembly method ensures the rapid formation of enclosed spaces, providing a stable working environment for subsequent internal construction, thus effectively addressing the challenges of efficiency, cost, and precision inherent in traditional construction methods.

[0022] S12. Place the building modules in the external area of ​​the functional building space; These building modules can be placed at the outer edge of the construction area, becoming part of the building and also part of the enclosure structure. The building modules can be hoisted using lifting equipment and fixed using methods such as bolting, welding, or pre-embedded connections.

[0023] The building modules feature exterior finishes. By pre-integrating these finishes into the modules, their exterior surfaces are already complete when the modules are installed in the external areas of functional building spaces. This significantly reduces the need for on-site exterior finish construction in confined spaces within high-density urban areas, effectively reducing environmental pollution such as noise and dust at construction sites and shortening the overall construction cycle. Furthermore, because the finishes are prefabricated and installed in a factory environment, their quality and precision are easier to control, enhancing the overall quality and aesthetics of the building. In addition, when these exterior-finished building modules enclose a space, they not only provide the necessary isolation environment for construction but also constitute the final external image of the building, allowing it to present a better visual effect during construction, blending more seamlessly into the urban landscape, and avoiding the visual disharmony issues caused by long-term exposure of the structural surfaces.

[0024] Several building modules enclose the functional building space to form a closed space isolated from the external environment; multiple building modules are arranged along the boundary line of the construction area, and they are connected to each other or connected by temporary connectors to form a continuous closed structure.

[0025] S13. Install the first prefabricated component in the interior area of ​​the functional building space; The first prefabricated component refers to the prefabricated parts used to form the main structure or functional units inside a functional building. These components can be prefabricated off-site, such as prefabricated beams, prefabricated columns, prefabricated floor slabs, prefabricated wall panels, prefabricated stair sections, and even prefabricated modules integrating some electromechanical pipelines. Standardized production in a factory environment can effectively improve the manufacturing precision and quality of components and shorten the on-site construction cycle. The internal area of ​​the construction space refers to the enclosed space isolated from the external environment, formed by building modules or building modules and some prefabricated components, used to support the internal structure and functional layout of the functional building. Erecting the first prefabricated component in this internal area typically involves transporting the prefabricated component to the designated location using hoisting equipment and performing precise positioning, connection, and fixation. Connection methods can include, but are not limited to, welding, bolting, and grouting to ensure reliable connections and overall stability between components and between components and the main structure. This step focuses on building the internal framework and functional zoning of the building, laying the foundation for subsequent interior decoration and equipment installation.

[0026] S14. Construction work is carried out in an enclosed space.

[0027] Once the enclosed space is formed, all subsequent construction activities, such as the erection of the main structure, interior decoration, and equipment installation, are carried out within this isolated area. For example, steel or concrete structures can be poured, walls can be built, pipelines can be laid, and decorative materials can be installed within the enclosed space. This construction method in an enclosed environment helps control the impact of dust, noise, and waste generated during construction on the surrounding environment, and provides a relatively safe and stable working environment for construction workers.

[0028] Furthermore, prefabricated components are installed in other areas of the functional building space, including: Following the construction sequence of from far to near and from outside to inside, the hoisting of precast components was completed layer by layer.

[0029] The "from far to near" construction sequence refers to prioritizing components located further away from main material storage areas, transport routes, or the operating radius of lifting equipment during the hoisting and installation of prefabricated components. Then, the work gradually moves towards locations closer to these areas. This strategy helps reduce interference from installed components with subsequent material transport and equipment operation, avoids repetitive handling or overlapping work, thereby optimizing on-site logistics and improving construction efficiency. For example, within a building's interior space, internal structural components far from main entrances or hoisting points can be installed first, followed by a gradual installation of components closer to these areas.

[0030] The "outside-inside" construction sequence refers to prioritizing the enclosure of the external area within the same construction zone or floor to isolate the construction environment from the external environment before proceeding with the construction inside the building.

[0031] "Completing the hoisting and installation of precast components layer by layer" refers to the process of hoisting and installing all precast components on a floor in a vertical, top-down sequence before proceeding to the next floor. This layered, segmented construction method ensures the structural integrity and stability of each floor, facilitates quality control and safety management, effectively organizes vertical transportation, avoids overlapping work between different floors, and improves the overall rhythm and continuity of construction. For example, after all the precast beams, columns, slabs, and other components on one floor have been installed and connected, the hoisting of components for the second floor can begin.

[0032] Through the aforementioned technical solutions, a systematic and streamlined construction management system can be established for the installation of prefabricated components within functional building spaces. This orderly construction sequence effectively solves problems such as logistical chaos and inefficiency that may arise during the installation of prefabricated components in confined spaces. Specifically, the "from far to near" strategy minimizes traffic congestion and material turnover paths at the construction site, reducing the risk of component collisions and damage; the "outside-to-inside" strategy ensures that the external structure is enclosed first, providing a stable working environment for subsequent internal molding, decoration, and equipment installation; and the "layer-by-layer completion" ensures the continuity of construction and the integrity of the structure, facilitating quality control and safety management. Overall, this solution significantly improves the efficiency, safety, and controllability of prefabricated component hoisting construction in confined spaces in high-density urban areas, ensuring that construction can be carried out efficiently and with high quality within enclosed spaces isolated from the external environment.

[0033] Furthermore, the top of the enclosed space can be in an open, closable, or closed state.

[0034] When the top of an enclosed space is open, it means the area above the construction site is completely open. This configuration is particularly suitable for construction phases requiring the vertical hoisting of large components, the movement of heavy equipment, or maximizing natural lighting and ventilation when weather conditions are favorable. The open configuration provides unobstructed vertical access, significantly improving construction flexibility and efficiency, especially in the early stages of building structure erection.

[0035] When the top of an enclosed space is openable, it means that the top structure of the enclosed space has the ability to be opened or closed as needed. This can be achieved by using methods such as retractable roofs, sliding roofs, or folding structures. The openable / closable configuration provides a high degree of adaptability for construction; for example, the top can be opened when hoisting operations are required, and closed when encountering severe weather (such as rain, snow, or strong winds) or when interior finishing is needed to control the environment. This configuration effectively balances the protection of the internal environment and the isolation from the external environment while ensuring construction progress.

[0036] When the top of an enclosed space is sealed, it means the area above the construction site is completely covered. This can be achieved through a fixed roof structure, a temporary fully enclosed canopy, or the permanent roof structure of the final building. Enclosure provides comprehensive weather protection for the construction area, effectively isolates external noise, and minimizes the spread of dust and pollutants generated during construction. This is particularly important in the delicate construction phases of interior decoration and electromechanical installation in environmentally sensitive, high-density urban areas, ensuring construction quality and significantly reducing disturbance to surrounding residents and the environment.

[0037] Second Embodiment See Figure 2-3 Unlike the first embodiment, the building module in the second embodiment cannot completely enclose the external area of ​​the functional building to form a closed area. The similarities will not be repeated.

[0038] Specifically, the enclosed construction method of this plan includes: S21. The functional building is divided into building modules, first prefabricated components, and second prefabricated components; the overall structure and function of the functional building are decomposed into several building modules and prefabricated components. Among them, the building modules are replicable standard building structures, and several building modules are horizontally spliced ​​and / or stacked and spliced ​​in the external area by hoisting.

[0039] S22. The building modules are set up in the external area of ​​the functional building space, and a second prefabricated component is built in the external area where no building modules are set up to connect the adjacent building modules. The second prefabricated component is a pre-manufactured component designed to compensate for the shortcomings of building modules in enclosing external areas. This second prefabricated component can take various forms, such as prefabricated steel frames, prefabricated concrete slabs, or composite material panels, and its size and connection methods can be customized according to the gaps and structural requirements of the actual construction site. The assembly of the second prefabricated component refers to its precise installation, through hoisting, or assembly, in external areas not covered by building modules, or its use to connect adjacent building modules, thereby forming a continuous and seamless external enclosure structure.

[0040] S23. Install dust and noise reduction barriers to the outside of the second prefabricated component so that the building module and the dust and noise reduction barriers together form a closed space; The dust and noise reduction fencing is securely fixed to the outer surface of the second prefabricated component using hooks, clips, bolts, etc., forming a continuous cover with the outside of the building module. Its purpose is to physically block the outward spread of dust generated at the construction site and to absorb or reflect construction noise, thereby reducing its impact on the surrounding environment. In this way, the building module and the dust and noise reduction fencing together constitute a complete, enclosed space isolated from the external environment, ensuring that dust and noise generated during construction are effectively controlled within this enclosed space.

[0041] The introduction of the second prefabricated component allows for the construction of a robust enclosure structure even in external areas where building modules are not continuously covered, thus eliminating potential isolation gaps. Simultaneously, the installation of dust-proof and noise-reducing barriers further enhances the environmental performance of the enclosed space, significantly reducing the pollution and disturbance of dust and noise generated during construction to the high-density urban environment. This not only improves the environmental management level of the construction site but also provides a quieter and cleaner living environment for surrounding residents, ensuring the feasibility and social acceptance of functional building construction within confined spaces.

[0042] S24. Install the first prefabricated component in the interior area of ​​the functional building space; The first prefabricated component refers to the prefabricated parts used to form the main structure or functional units inside a functional building. These components can be prefabricated off-site, such as prefabricated beams, prefabricated columns, prefabricated floor slabs, prefabricated wall panels, prefabricated stair sections, and even prefabricated modules integrating some electromechanical pipelines. Standardized production in a factory environment can effectively improve the manufacturing precision and quality of components and shorten the on-site construction cycle. The internal area of ​​the construction space refers to the enclosed space isolated from the external environment, formed by building modules or building modules and some prefabricated components, used to support the internal structure and functional layout of the functional building. Erecting the first prefabricated component in this internal area typically involves transporting the prefabricated component to the designated location using hoisting equipment and performing precise positioning, connection, and fixation. Connection methods can include, but are not limited to, welding, bolting, and grouting to ensure reliable connections and overall stability between components and between components and the main structure. This step focuses on building the internal framework and functional zoning of the building, laying the foundation for subsequent interior decoration and equipment installation.

[0043] S25. Construction work is carried out in an enclosed space.

[0044] Wall installation refers to the construction and fixation of walls inside or outside the building structure. This can include installing prefabricated wall panels, lightweight partitions, or traditional masonry, aiming to divide space, provide structural support, sound and heat insulation, and fire protection. Wall installation within enclosed spaces effectively controls dust and noise during construction, reducing the impact on the surrounding environment. Interior decoration refers to the decoration and functional treatment of the building's interior space. This encompasses flooring, ceiling installation, wall painting or cladding, door and window installation (if not pre-installed with modules), and the installation of fixed furniture. Completing interior decoration within enclosed spaces ensures that the drying and curing process of decoration materials is not disturbed by the external environment, improving decoration quality and further reducing the visual and auditory impact of construction on the outside world. Mechanical and electrical system installation refers to the layout and connection of the building's required mechanical, electrical, and piping systems. This includes, but is not limited to, electrical wiring, lighting installation, water supply and drainage pipe laying, HVAC system installation, and the integration of low-voltage systems such as fire protection and security. Installing electromechanical systems in an enclosed space facilitates coordination between systems, ensures installation accuracy and smooth system commissioning, and avoids interference with external traffic and pedestrians caused by high-altitude operations or complex pipeline layout.

[0045] Through the aforementioned technical solution, this application ensures that the entire construction process, from the erection of the main structure to the completion of internal functions, is completed within a closed space isolated from the external environment. Because these meticulous construction steps are all carried out in a controlled, enclosed environment, it is beneficial to improve construction quality and efficiency, reduce interference from overlapping operations, and ensure the safety of construction personnel. Ultimately, this method can efficiently and with high quality deliver a fully functional building with minimal impact on the surrounding environment.

[0046] Furthermore, the building modules are positioned in the wide outer area. The second prefabricated component is erected in the narrow outer area.

[0047] Building modules are typically replicable standard building structures with specific dimensions and structural strength, requiring ample space for hoisting, positioning, and connection operations. Placing these larger building modules in relatively spacious and easily accessible areas of the external environment allows for full utilization of these areas, ensuring stable installation and providing stable support for subsequent construction activities. For example, in the external environment, selecting areas that can accommodate the full dimensions of the building modules and provide sufficient working space allows for horizontal or stacked assembly via hoisting.

[0048] The second prefabricated component is mainly used to connect adjacent building modules and serves as a supporting structure for dust and noise reduction enclosures. Compared to building modules, the second prefabricated component typically offers greater adaptability and flexibility; its size and structure can be customized or adjusted according to the specific conditions of narrow areas. When erected in areas with limited space where it is unsuitable to install complete building modules, it can effectively fill these gaps and complete the enclosure of enclosed spaces.

[0049] This application allows for flexible allocation of building modules and second prefabricated components based on the actual width of the external area of ​​the construction site. This differentiated layout strategy enables the full utilization of the structural advantages of the building modules in wide areas, while narrow areas are effectively enclosed through the flexibility of the second prefabricated components, significantly improving the utilization efficiency of limited external space and avoiding space waste. Furthermore, the easier installation of building modules in wide areas and the reduced construction difficulty and time due to the adaptability of the second prefabricated components in narrow areas improve overall construction efficiency. More importantly, this rational combination makes the entire enclosed structure more adaptable to site conditions, enhancing the overall stability and safety of the enclosed space. Ultimately, it ensures that even in complex site conditions and with uneven external area widths, an enclosed space isolated from the external environment can be efficiently and completely formed, thereby better achieving dust and noise reduction and ensuring a clean and safe construction environment.

[0050] Third Embodiment The third embodiment of this solution discloses a building constructed using closed construction methods, including building modules and prefabricated components. The building modules and prefabricated components are constructed using the closed construction methods of the first or second embodiment to form the building.

[0051] This enclosed construction solution addresses the complex application scenarios of high-density urban areas with limited space, reshaping the construction process through meticulous design. Integrated modules enable rapid enclosure of the building's street-facing facade, facilitating a quick transformation of the urban visual identity and minimizing negative impacts on the cityscape. Flexible construction barriers, designed for dust control and noise reduction, and integrating demolition and construction, enclose the remaining building facade, creating a closed construction site. Internally, supplemented by frame structures and other structural forms, this transforms traditional construction into a low-impact "interior decoration project," effectively reducing noise and dust pollution's impact on the daily lives of surrounding residents and significantly shortening the duration of disruption.

[0052] The "module + frame" technology adopted in this scheme is derived from modular building products. Considering the connection of nodes and the convenience of construction, steel-concrete composite module + steel frame structure and concrete module + concrete frame structure (precast or cast-in-place) can be used. For low-rise and multi-story buildings, concrete module + cast-in-place frame structure is preferred, which has better cost economy.

[0053] Factory-prefabricated building modules (which can be small modules including exterior finishes) are primarily used for the rapid enclosure of the street-facing facade of proposed buildings, enabling the rapid formation of the urban visual identity and minimizing negative impacts on the city's landscape. The remaining facade is enclosed using dust-proof and noise-reducing flexible construction fencing products. This modular + fencing approach creates a completely enclosed construction environment, transforming the building project into a low-impact interior finishing project.

[0054] The electromechanical and interior decoration systems are constructed according to the company's relevant product matching practices. Modular components can be integrated in the factory or installed on-site together with the frame components. Prefabricated decoration components such as prefabricated wall panels, integrated bathrooms, and quick-installation electromechanical pipelines are used to reduce on-site wet work and the use of adhesives, thereby improving construction efficiency, controlling construction quality, and shortening the construction period.

[0055] See Figure 4-6 The building constructed based on the construction method of the second embodiment includes a building module 10, a first prefabricated component 201, a second prefabricated component 202, and a flexible soundproof enclosure 30. The building module 10 is located in the outer area; the first prefabricated component 201 is located in the inner area, and the second prefabricated component 202 is located in the outer area to connect adjacent building modules 10; the flexible soundproof enclosure 30 is installed outside the second prefabricated component 202, and a plurality of building modules 10 and a plurality of flexible soundproof enclosures 30 are combined to enclose the building space to form a closed space isolated from the external environment.

[0056] By constructing the building using building modules 10, first prefabricated components 201, and second prefabricated components 202, construction efficiency and adaptability are improved. The building modules 10, first prefabricated components 201, and second prefabricated components 202 become the main building structure after construction. The flexible soundproof enclosure 30 serves as a recyclable auxiliary material for the construction of subsequent buildings. The combined use of the flexible soundproof enclosure 30 and the prefabricated components enables the construction of walls, interior decoration, and electromechanical systems within a fully enclosed space, transforming the building project into a low-impact interior decoration project and achieving quiet construction.

[0057] The flexible soundproof barrier 30 is directly installed outside the prefabricated components 20 during construction, achieving partial or complete enclosure of the construction site. This significantly reduces the impact of noise and dust generated during construction on the lives of surrounding residents, reduces the occupation of surrounding roads, and improves the urban environment during construction.

[0058] In one embodiment, the building module 10 is a replicable standard building structure, and several building modules 10 are joined horizontally or stacked to form the external area. Designing the building module 10 as a replicable standard building structure, and allowing it to form the external area through horizontal / vertical joining and vertical stacking, significantly improves the standardization of the building and construction efficiency. The replicable standard building structure ensures mass production and quality control of the modules, effectively reducing manufacturing costs and on-site construction difficulties.

[0059] In one embodiment, the building module 10 is located on the periphery of the building, and the second prefabricated component 202 is located above the building module 10. The top of the building module 10 forms a construction platform for erecting the second prefabricated component 202.

[0060] By placing the building module 10 on the periphery of the building and positioning the prefabricated component 20 above it, the construction of the second prefabricated component 202 can be carried out in a relatively controlled and centralized internal space, reducing interference with the external environment. Furthermore, utilizing the top of the already constructed building module 10 as a construction platform for erecting the prefabricated component 20 provides a stable and safe working surface for high-altitude operations, eliminating the need for additional large scaffolding or independent construction platforms. This significantly improves construction efficiency, reduces construction costs, and ensures the safety of construction personnel.

[0061] In one embodiment, the prefabricated component 20 includes a crossbeam 21 and a column 22. Several crossbeams 21 at the same height are connected to each other, and crossbeams 21 at different heights are connected by the column 22.

[0062] The proper connection between beam 21 and column 22 ensures the stability and load-bearing capacity of the entire irregular building structure, effectively avoiding structural safety hazards caused by unclear component connections. Furthermore, this modular beam-column system provides greater flexibility in the design of irregular building areas, enabling complex and varied irregular building structures to be realized in a controllable and reliable manner.

[0063] In one embodiment, the flexible soundproof enclosure 30 includes side enclosures and a top enclosure. The side enclosures are detachably connected between several columns 22, and the top enclosure is detachably connected between several beams 21. By subdividing the flexible soundproof enclosure 30 into side enclosures and a top enclosure, and detachably connecting them to the columns 22 and beams 21 of the prefabricated components 20 respectively, a comprehensive and three-dimensional enclosure of the construction site within an irregular building area is achieved.

[0064] In one embodiment, the prefabricated component 20 further includes a floor slab 23, which is connected between a plurality of beams 21 at the same height and between beams 21 at different heights and columns 22.

[0065] The installation of floor slab 23 enables irregular building structures to form complete and functional floor spaces. The introduction of floor slab 23 also enhances the overall structural rigidity and stability of irregular building areas, enabling them to better withstand vertical loads and providing reliable support for subsequent interior decoration and equipment installation. This makes the entire building more functional and adaptable.

[0066] It should be noted that the floor slab 23 installed on the side should be inside the flexible sound insulation barrier 30. After the floor slab 23 on the side is installed, the corresponding outer flexible sound insulation barrier 30 can be removed.

[0067] In one embodiment, the outer surface color of the flexible soundproof enclosure 30 is coordinated with the outer surface color of the building module 10 to harmonize with the surrounding environment and reduce the impact on the urban landscape.

[0068] The outer surface color of the flexible soundproof enclosure 30 is designed to be in harmony with the surrounding environment. This effectively avoids the visual abruptness and disharmony caused by color differences between the construction area and the completed area, improves the overall aesthetics of the building during construction, reduces the visual impact on the surrounding environment, and enables the entire building project to maintain a good visual image at different construction stages.

[0069] In one embodiment, see further. Figure 2-3 The flexible soundproof enclosure 30 includes a body 31 and an overlapping portion 32 connected to the edge of the body 31. The overlapping portion 32 has a connection hole 321. The body 31 includes a first protective surface layer 311, a first sound-absorbing layer 312, a sound-insulating layer 313, a second sound-absorbing layer 314, and a second protective surface layer 315 that are stacked and connected in sequence. The overlapping portion 32 is provided with Velcro or magnets.

[0070] The flexible soundproof enclosure 30 features a multi-layered structure 31, including a protective surface layer, a sound-absorbing layer, and a sound-insulating layer 313. This composite structure significantly enhances the enclosure's sound insulation and absorption performance, effectively blocking construction noise from propagating outwards and absorbing internally reflected sound, thereby greatly reducing noise pollution from the construction area and improving the working environment for construction workers. Meanwhile, the connecting holes 321 and Velcro or magnets on the overlapping sections 32 provide diverse and convenient connection methods for the flexible soundproof enclosure 30. The connecting holes 321 ensure a robust mechanical connection between the enclosure and the supporting structure, guaranteeing the enclosure's stability under external loads such as wind. The Velcro or magnets provide convenient quick installation and disassembly, particularly suitable for the rapid assembly and adjustment of prefabricated components 20 in modular buildings, greatly shortening the construction cycle and reducing labor costs. This design enables the flexible soundproof enclosure 30 to not only possess excellent acoustic performance but also ensure construction efficiency and ease of operation, providing an efficient, flexible, and environmentally friendly noise control solution for modular buildings that can be enclosed for construction.

[0071] Specifically, both the first protective layer 311 and the second protective layer 315 are made of one of the following materials: PVC flame-retardant knife-coated fabric, PVC flame-retardant mesh fabric, three-proof fabric, or silicone fiberglass fabric. These materials all possess excellent flame-retardant properties, effectively reducing the fire risk at the construction site and ensuring the safety of personnel and property. Simultaneously, these materials also exhibit good weather resistance, tensile strength, and tear resistance, enabling the flexible soundproof barrier 30 to withstand long-term and stable resistance to wind and rain erosion, ultraviolet radiation, and physical wear during construction, thereby ensuring the durability of its sound insulation effect.

[0072] In one embodiment, the first sound-absorbing layer 312 and the second sound-absorbing layer 314 are both made of one of the following materials: glass fiber sound-absorbing cotton, flame-retardant polyester fiber sound-absorbing cotton, or rock wool. Using one of these materials for the first sound-absorbing layer 312 and the second sound-absorbing layer 314 in the flexible soundproof enclosure 30 can significantly improve the enclosure's sound absorption performance. These materials all have excellent porous structures and fiber properties, effectively absorbing noise of various frequencies generated during construction, especially mid-to-high frequency noise, thereby reducing sound wave reflection and propagation. This not only enhances the noise isolation effect of the flexible soundproof enclosure 30 against the external environment but also improves the acoustic environment inside the enclosure, providing more comfortable working conditions for construction workers.

[0073] In one embodiment, the sound insulation layer 313 is made of damping sound insulation felt. This material, with its high density and excellent damping properties, can efficiently absorb and attenuate sound wave energy, converting it into heat energy, thereby significantly improving the overall sound insulation performance of the flexible soundproof enclosure 30.

[0074] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
