Description

Technical Field

[0001] This disclosure relates to the field of building construction technology, and more particularly to a prefabricated component for archways. Background Technology

[0002] In the field of architectural decoration, arched doorways are a common interior transition structure, widely used in the connection parts between doorways, windowways, or walls.

[0003] Traditional archway construction relies heavily on on-site manual work, typically using gypsum board, wood, or other materials, which are cut, spliced, and sanded to form the arched structure. This method has several drawbacks: First, manual work demands high skill levels from the workers, making it difficult to guarantee the flatness and smoothness of the curved surface, easily leading to dimensional deviations or uneven surfaces, affecting aesthetics. Second, on-site processing is time-consuming and inefficient, and the cutting and sanding processes generate significant dust and noise, negatively impacting the construction environment and worker health. Furthermore, traditional gypsum board materials are prone to cracking and deformation over long-term use, especially in environments with significant humidity fluctuations, resulting in high maintenance costs.

[0004] In existing technologies, some solutions attempt to simplify the construction process of curved archways by using prefabricated components. However, these prefabricated components are typically designed with simple planar or regular geometric shapes, making it difficult to meet the complex curved surface requirements of curved archways. Furthermore, existing prefabricated components often rely on adhesive bonding or simple mechanical fixing methods during installation, lacking optimized design for curved structures. This results in gaps easily appearing at joints, insufficient installation stability, and difficulty in adapting to the needs of different wall thicknesses and construction scenarios.

[0005] Therefore, there is an urgent need for a component that can overcome the shortcomings of existing archway construction techniques, in order to improve construction efficiency, ensure the flatness and aesthetics of the arched surface, enhance the stability and adaptability of installation, and meet the needs of modern architectural decoration for high-quality archways.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0026] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Figure 1 This is a schematic diagram of a prefabricated component for a gate installed on a gate, according to one embodiment of this disclosure.

[0028] Figure 2 This is a partial structural diagram of the mountain pass before the prefabricated components disclosed herein are installed.

[0029] refer to Figure 1 and Figure 2 The prefabricated component for a doorway disclosed herein includes: a first prefabricated body 100 having a first arcuate surface 101; a second prefabricated body 200 having a second arcuate surface 202; the first prefabricated body 100 and the second prefabricated body 200 can be installed on the doorway, and the first arcuate surface 101 and the second arcuate surface 202 are located on the same arcuate surface.

[0030] In this context, "archway" refers to an opening in a building's interior space that connects adjacent functional areas (such as the living room and dining room, or the bedroom and corridor) without a door.

[0031] The first precast body 100 and the second precast body 200 can be fixedly connected to the wall base or substrate structure through their respective installation structures.

[0032] In the installed state, the first arc-shaped surface 101 and the second arc-shaped surface 202 together form a continuous and smooth arc-shaped decorative surface, which extends along the contour of the archway opening to form a visually seamless curved surface effect.

[0033] The first precast body 100 and the second precast body 200 can be precast in the factory using high-precision molds. The materials can be glass fiber reinforced gypsum (GRG), fiber cement board, composite resin or other decorative materials with plasticity, dimensional stability and surface smoothness. This disclosure does not make any special limitations on these materials.

[0034] The first arc-shaped surface 101 and the second arc-shaped surface 202 have the same geometric curvature and can be designed as part of the same arc segment or a gradually changing curved surface, ensuring that the two are spatially located within the same arc-shaped surface after being joined, thus avoiding steps, misalignments, or visual breaks. The radius of the arc-shaped surface can be set according to design requirements, and this disclosure does not impose any special limitations on it.

[0035] Furthermore, during installation, the edges of the first precast body 100 and the second precast body 200 are brought close together or joined, forming a seam along the arc-shaped direction. This seam is located in a non-primary visual area of ​​the arc-shaped surface (such as the top center or side transition area) to reduce the impact of splicing marks on the overall aesthetics. The seam can be filled with repair material, sanded, and covered with a finishing layer to achieve a "hidden splicing" decorative effect.

[0036] The prefabricated component disclosed herein decomposes the arc shape into two independently manufactureable prefabricated bodies, realizing the modular disassembly and rapid on-site assembly of complex curved surface structures, and solving the problem of inconvenient installation of traditional whole arc components.

[0037] Furthermore, the structural design of the prefabricated components allows them to be adapted to walls of different thicknesses. By adjusting the coverage dimensions of the first and second prefabricated components in the wall thickness direction (i.e., the extension length along the depth of the opening), the exposed curved surfaces of the two components can remain coplanar after installation, thus adapting to common partition wall thicknesses such as 100mm, 150mm, and 200mm, improving the versatility and construction flexibility of the components.

[0038] Figure 3 Observing from different perspectives Figure 1 The schematic diagram of the prefabricated component shown shows that the first arc-shaped surface 101 and the second arc-shaped surface 202 are located on the same arc-shaped surface.

[0039] Figure 4 yes Figure 1 A schematic diagram of the prefabricated components after the archway has been removed.

[0040] refer to Figure 4 In some embodiments of this disclosure, the first prefabricated body 100 has a first mounting structure 103 (right-angled body), based on which the first prefabricated body 100 can be mounted on the archway.

[0041] The second prefabricated body 200 has a second mounting structure 203 (right-angled body), based on which the second prefabricated body 200 can be installed on the archway.

[0042] The first preform 100 and the second preform 200 are installed on the archway in a mutually cooperating manner so that the first arc-shaped surface 101 and the second arc-shaped surface 202 are located on the same arc-shaped surface.

[0043] refer to Figure 4 The first mounting structure 103 and the second mounting structure 203 can both be right-angled structures extending towards the back of the precast body, with an "L"-shaped or L-shaped cross-section, used to achieve a stable connection with the wall base or substrate structure in the archway area.

[0044] The first mounting structure 103 is located on the back of the first preform 100 and is used to fix the first preform 100 to the plaster substrate or keel base of the archway; similarly, the second mounting structure 203 is located on the back of the second preform 200 and is used to fix the second preform 200 to the plaster substrate or keel base of the archway.

[0045] In some embodiments of this disclosure, the "right-angled" structure consists of two mutually perpendicular mounting surfaces, which are parallel to the two mutually perpendicular wall planes of the archway.

[0046] In some embodiments of this disclosure, the dimensions, thickness, or extension length of the first mounting structure 103 and the second mounting structure 203 can be adjusted according to the actual wall thickness, so that prefabricated components of different specifications can be adapted to common partition wall thicknesses such as 100mm, 150mm, and 200mm, further improving the versatility and construction flexibility of the components.

[0047] In addition, the installation structure is prefabricated in the factory and can be cast and manufactured simultaneously with the precast body (such as GRG), avoiding problems such as loosening, corrosion or inaccurate positioning caused by adding metal hangers on site.

[0048] refer to Figure 4 For the prefabricated components for the archway in the various embodiments described above, preferably, one of the first prefabricated body 100 and the second prefabricated body 200 has a splicing structure 104 for splicing connection, and the other of the first prefabricated body 100 and the second prefabricated body 200 cooperates with the splicing structure 104 so that the first prefabricated body 100 and the second prefabricated body 200 are installed on the archway in a splicing connection manner.

[0049] To improve the connection accuracy and installation efficiency between the first precast body 100 and the second precast body 200, preferably, a splicing structure 104 for splicing connection is provided on one of the first precast body 100 and the second precast body 200, and the other precast body body cooperates with the splicing structure, so that the first precast body and the second precast body can achieve rapid alignment and stable connection during installation through plug-in or splicing methods.

[0050] In some embodiments of this disclosure, reference continues to be made to Figure 4 The interlocking structure 104 is disposed on the mating edge of the first precast body 100 or the second precast body 200. Figure 4 The interlocking structure is set on the first precast body and extends along the arc direction. It can guide the two precast bodies to automatically correct their positions during installation, reducing manual adjustment time.

[0051] This interlocking connection method enables the two prefabricated bodies to be positioned collaboratively in three-dimensional space without relying on external clamps or temporary supports, ensuring that the first arc surface 101 and the second arc surface 202 are precisely on the same arc surface.

[0052] The interlocking structure design not only improves the convenience of on-site assembly but also enhances the overall structural rigidity of the joint area, effectively suppressing relative displacement caused by temperature and humidity changes or slight vibrations, thereby reducing the risk of cracking later. Furthermore, after assembly, the gaps at the joints are small and uniform, facilitating seamless repair with subsequent materials and further improving the aesthetics and integrity of the decorative surface.

[0053] In some implementations, the interlocking structure is prefabricated in one piece in the factory and manufactured simultaneously with the precast body to ensure dimensional accuracy and structural strength.

[0054] Figure 5 and Figure 6 A structural schematic diagram of the first preform 100 of one embodiment of the present disclosure is shown from different perspectives.

[0055] Figure 7 and Figure 8 A schematic diagram of the structure of a second preform 200 according to one embodiment of the present disclosure is shown from different perspectives.

[0056] refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 In some embodiments of this disclosure, the interlocking structure 104 on the first prefabricated body 100 is an arc-shaped plate portion, which has an arc-shaped surface 1041.

[0057] The curved surface 1041 of the curved plate can fit against the curved back surface 201 of the second preform 200.

[0058] In some embodiments of this disclosure, reference is made to Figure 5 and Figure 6 The arc-shaped plate described above is an arc-shaped insert structure that extends outward from the docking edge of the first precast body 100. Its cross-section can be arc-shaped, and it extends continuously along the height direction of the precast body.

[0059] The curved surface 1041 of the curved plate has the same radius of curvature or similar geometric features as the exposed curved surface 101 of the first preform 100, ensuring that the first preform 100 and the curved back surface 201 of the second preform 200 achieve surface contact bonding during the assembly process, rather than point or line contact.

[0060] During installation, when the first precast body 100 and the second precast body 200 are relatively close, the curved plate slides in along the curved back surface 201 of the second precast body 200, forming a guiding embedding effect. This curved surface fitting splicing method can not only effectively guide the two precast bodies to automatically align and reduce installation deviation, but also form a large contact area in the connection area, significantly improving the structural stability and deformation resistance of the joint.

[0061] More importantly, since the arc-shaped surface 1041 of the interlocking structure 104 and the arc-shaped back surface 201 of the second prefabricated body 200 have good geometric matching, the gap between the two is uniform and extremely small after the splicing is completed, which is conducive to the subsequent use of repair materials for seamless treatment, further ensuring the continuity and aesthetics of the overall arc-shaped decorative surface.

[0062] In addition, the arc-shaped plate can be integrally formed in the factory using a mold as part of the first preform 100 body, and manufactured synchronously with the preform body body to ensure accurate spatial orientation and high dimensional accuracy, and avoid misalignment or interference during on-site assembly.

[0063] Of course, the interlocking structure described above can also be formed only on the second preform 200. That is, the interlocking structure described above is an arc-shaped plate part set on the mating side edge of the second preform 200, whose arc-shaped surface can fit with the arc-shaped back of the first preform 100. The second preform 200 serves as the "insertion side" and the first preform 100 serves as the "inserted side". The two can still achieve rapid alignment and stable connection through guide embedding.

[0064] Regardless of whether the interlocking structure is set on the first precast body 100 or the second precast body 200, its technical principle, connection method and the technical effect achieved are the same: both can achieve advantages such as surface contact bonding, automatic centering, uniform gap and structural stability.

[0065] Continue to refer to Figure 5 and Figure 6 In some embodiments of this disclosure, the arcuate surface 1041 of the arcuate plate portion and the preform having the arcuate plate portion ( Figure 5 The arc-shaped surfaces (i.e., the first arc-shaped surface 101) of the first preform 100 are spatially offset.

[0066] This staggered layout avoids structural interference between the interlocking structure and the exposed curved surface, which is conducive to achieving deeper interlocking and ensuring the integrity and smooth transition of the exposed curved surface.

[0067] In some other embodiments of this disclosure, the first prefabricated body 100 has a first interlocking structure (not shown), the second prefabricated body 200 has a second interlocking structure (not shown), and the first prefabricated body 100 and the second prefabricated body 200 are installed on the archway in a mutually cooperating manner based on the first interlocking structure and the second interlocking structure.

[0068] Preferably, the first interlocking structure is a protrusion and the second interlocking structure is a groove; or, the second interlocking structure is a protrusion and the first interlocking structure is a groove.

[0069] The first and second prefabricated bodies are installed on the archway by interlocking the protrusions and grooves.

[0070] Preferably, the first interlocking structure is disposed on the mating side edge of the first prefabricated body 100, and the second interlocking structure is disposed on the mating side edge of the second prefabricated body 200; The mating edge is the edge where two prefabricated bodies are close to or mated together when they are installed.

[0071] In the above embodiment, the first interlocking structure and the second interlocking structure form a matching connection pair, one of which is a protruding convex part and the other is a recessed groove. The two are interlocked by a plug-in method. The cooperation between the convex part and the groove has a guiding function, which can guide the first prefabricated body 100 and the second prefabricated body 200 to automatically align during the installation process, reducing manual adjustment time and improving assembly efficiency.

[0072] The cross-sectional shape of the protrusion and the groove can be trapezoidal, T-shaped or arc-shaped, etc., as long as they can achieve plug-in fit and prevent separation, they all fall within the protection scope of this disclosure.

[0073] When the first interlocking structure is a protrusion and the second interlocking structure is a groove, the first prefabricated body serves as the "insertion side" and the second prefabricated body serves as the "acceptance side"; the reverse is also possible. Regardless of the configuration, a stable splicing connection can be achieved, and the spliced ​​joint is tight with no obvious step difference, which is beneficial for subsequent seamless processing.

[0074] The first and second interlocking structures can both be integrally molded with the precast body in the factory, preferably using GRG molds to ensure dimensional accuracy and structural strength. After assembly, the spatial orientation of the two precast bodies is controlled by the interlocking structures themselves, maintaining a coplanar state without relying on external clamps.

[0075] For the prefabricated components for the archway in the various embodiments described above, preferably, the dimension of the first arcuate surface in the thickness direction of the wall to which the archway belongs is different from the dimension of the second arcuate surface in the thickness direction of the wall to which the archway belongs.

[0076] Specifically, the dimensions of the first arc-shaped surface 101 and the second arc-shaped surface 202 in the wall thickness direction (i.e., the extension length along the longitudinal direction of the archway opening) can be differentiated according to the actual wall thickness or design requirements.

[0077] For example, in some asymmetrical archway designs, one side of the wall may be thinner (e.g., 100mm) while the other side is thicker (e.g., 200mm). By adjusting the dimensions of the curved surfaces of the first precast body 100 and the second precast body 200 to accommodate the different thicknesses on both sides of the wall, it is still possible to ensure that the first curved surface 101 and the second curved surface 202 are located on the same curved surface after installation, forming a continuous and smooth decorative effect. This design with size differences not only improves the compatibility of precast components with non-standard wall thicknesses but also allows for flexible modular assembly in complex architectural scenarios. For example, in some specially designed interior spaces, the archway may involve partition walls of different thicknesses or need to be matched with different types of base structures (such as plaster substrates or concrete walls). The size-differentiated curved surfaces can effectively cope with these changes, ensuring the integrity and aesthetics of the curved decorative surface after installation. In addition, size differences can be achieved through adjustments to the precast molds in the factory, without the need for on-site modifications or cutting, maintaining the high precision and consistency of the precast components. At the same time, this design does not affect the connection effect of the interlocking structure. Whether it is the interlocking method of the curved plate or the convex and groove, a stable connection and coplanar effect can be achieved through reasonable geometric matching.

[0078] In the installed state, the prefabricated components of this disclosure have a gap or no gap between the mating edge of the first prefabricated body and the mating edge of the second prefabricated body.

[0079] Specifically, the mating edge refers to the edge area where the first precast body 100 and the second precast body 200 are close to or mated with each other in the installed state, usually located at the splicing point of the curved surface.

[0080] In some embodiments, the mating edges of the first prefabricated body 100 and the second prefabricated body 200 are designed to be gapless, meaning that their edges are in direct contact or tightly fitted, forming a seamless appearance. This gapless design is suitable for scenarios with high decorative requirements, such as high-end residences or hotel lobbies requiring highly smooth and continuous curved surfaces. High-precision molding in the factory and precise matching of the interlocking structures (such as the connection between curved panels or protrusions and grooves) ensure a gapless fit between the mating edges, reducing the complexity of subsequent seam treatment.

[0081] In other embodiments, a gap is designed between the mating edges of the first precast body 100 and the second precast body 200. This gap is typically small (e.g., 0.5mm to 2mm), and a seamless visual effect is achieved through subsequent joint treatments (e.g., filling with elastic sealant, applying crack-resistant mesh tape, and sanding). The gap design can tolerate minor dimensional deviations at the construction site or unevenness of the wall substrate, reducing installation difficulty caused by excessively high precision alignment requirements.

[0082] Furthermore, the gap facilitates adjustment of the relative positions of the two prefabricated bodies during the splicing process, ensuring that the first arc-shaped surface 101 and the second arc-shaped surface 202 are precisely located on the same arc-shaped surface. The size of the gap can be pre-set in the factory mold according to actual construction needs and design requirements, and can be made invisible after installation by filling with repair materials and surface treatment.

[0083] Regardless of whether the design has gaps or no gaps, precise positioning is achieved through the interlocking structure of the first precast body 100 and the second precast body 200 (such as curved panels or protrusions and grooves), ensuring the coplanarity of the curved surfaces and the stability of the overall structure. This flexible gap design not only improves the adaptability of precast components to different construction conditions, but also takes into account installation efficiency and the aesthetics of the decorative surface, making it suitable for various architectural scenarios, such as archway decoration in residential, commercial, or public buildings.

[0084] In some embodiments of the prefabricated components described above, the prefabricated components further include: a third prefabricated body (not shown) having a third arcuate surface; the first prefabricated body, the second prefabricated body, and the third prefabricated body can be installed on the archway, and the first arcuate surface, the second arcuate surface, and the third arcuate surface are located on the same arcuate surface.

[0085] Specifically, the third precast body is an independent precast component, and its design principle is similar to that of the first precast body 100 and the second precast body 200. It is precast in the factory using high-precision molds, and the material can be glass fiber reinforced gypsum (GRG) or other decorative materials with plasticity, dimensional stability and surface smoothness.

[0086] The geometric curvature of the third arc-shaped surface is consistent with that of the first arc-shaped surface 101 and the second arc-shaped surface 202, ensuring that the three together form a continuous and smooth arc-shaped decorative surface after installation, extending along the contour of the archway opening to achieve a visually seamless curved surface effect.

[0087] The introduction of a third prefabricated element further expands the modular design of prefabricated components, making it suitable for more complex archway shapes or larger openings. In different implementations, the placement of the third prefabricated element is flexible and can be adjusted according to actual design requirements and construction scenarios, including the following combinations: 1. A third prefabricated body is located between the first and second prefabricated bodies: In this configuration, the third prefabricated body serves as an intermediate transition member, connected to the first prefabricated body 100 and the second prefabricated body 200 via an interlocking structure or a butt joint. For example, one butt joint edge of the third prefabricated body mates with the butt joint edge of the first prefabricated body 100, and the other butt joint edge mates with the butt joint edge of the second prefabricated body 200. The interlocking structure can be... Figures 4 to 8 The design of the curved panel shown, or the use of interlocking protrusions and grooves, ensures that the curved surfaces of the three components (first curved surface 101, second curved surface 202, and third curved surface) are precisely located on the same curved surface. This configuration is suitable for wider archway openings, achieving a smoother curved transition by adding intermediate components, reducing the span of individual precast structures, and lowering manufacturing and installation difficulties.

[0088] II. First Precast Body Located in the Middle: In this configuration, the first precast body 100 is located between the third precast body and the second precast body 200. The mating edges on both sides of the first precast body 100 are connected to the mating edges of the third precast body and the second precast body 200 respectively through an interlocking structure or a direct mating method. The interlocking structure can be referenced. Figure 4 The arc-shaped panel design shown may employ a combination of protrusions and grooves. The first precast body 100 serves as the core component, supporting the main arc-shaped surface portion, while the third and second precast bodies 200 serve as supplementary components on both sides, together forming a complete arc-shaped decorative surface.

[0089] III. Second Precast Body in the Middle: In this configuration, the second precast body 200 is located between the first precast body 100 and the third precast body. The mating edges on both sides of the second precast body 200 are connected to the mating edges of the first precast body 100 and the third precast body through an interlocking structure or a direct mating method. Similarly, the interlocking structure can adopt an arc-shaped plate or a design of protrusions and grooves to ensure that the arc surfaces of the three are coplanar. The second precast body 200, as the intermediate component, is responsible for the main arc transition, while the first precast body 100 and the third precast body, as supplementary components on both sides, jointly complete the decorative effect of the archway.

[0090] In any of the above configurations, the third prefabricated body has an installation structure similar to that of the first prefabricated body 100 and the second prefabricated body 200, such as a right-angled structure (see reference). Figure 4 The first installation structure 103 and the second installation structure 203 are used to achieve a stable connection with the gypsum board substrate or keel base of the archway. The size and shape of the installation structure can be adjusted according to the wall thickness to accommodate common partition wall thicknesses such as 100mm, 150mm, and 200mm. The installation method of the third precast body is the same as that of the first precast body 100 and the second precast body 200. The structural accuracy is ensured by integral molding in the factory, avoiding problems caused by adding hangers on site.

[0091] Furthermore, the mating edges of the first precast body 100, the second precast body 200, and the third precast body can be designed with or without gaps. A gapless design achieves a tight fit through the use of high-precision molds and interlocking structures, suitable for scenarios with extremely high decorative requirements. A design with gaps (typically 0.5mm to 2mm) achieves a seamless visual effect through subsequent joint treatments (such as filling with elastic sealant, applying anti-crack mesh tape, and polishing), adapting to dimensional deviations or uneven substrate conditions on the construction site. Regardless of the design, it ensures that the curved surfaces of the three precast bodies are on the same curved surface, maintaining the continuity and aesthetics of the overall decorative surface.

[0092] The introduction of a third prefabricated body not only enhances the modular flexibility of prefabricated components but also enables the handling of more complex archway shapes. For example, in ultra-wide archways or openings with multiple curved transitions, the combination of three prefabricated bodies can effectively share the structural span, improve installation accuracy and stability, while maintaining the smoothness and consistency of the curved surfaces.

[0093] The prefabricated components of the various embodiments described above can be mounted on the archway via a gypsum substrate.

[0094] Specifically, gypsum board substrate refers to the gypsum board base layer that is pre-installed in the wall opening area of ​​the archway. It is usually a single layer or multiple layers of gypsum board, which is fixed to the wall frame or keel structure to form a flat installation base.

[0095] The first precast body 100, the second precast body 200, and the optional third precast body are connected by their respective installation structures (such as...). Figure 4 The first mounting structure 103 and the second mounting structure 203 shown are fixedly connected to the gypsum substrate. The mounting structure is usually an L-shaped or L-shaped right-angled structure, with its two mutually perpendicular mounting surfaces fitting against the surface of the gypsum substrate and the side wall of the archway opening, respectively, and is fixed to the gypsum substrate by bolts, expansion anchors or special connectors (such as metal keel hangers).

[0096] During installation, the wall surface in the archway area can be cleaned to ensure that the gypsum board substrate is flat and free of obvious bumps or debris. The joists (such as top and bottom joists) can be pre-fixed onto the gypsum board substrate, and adjusting the level and elevation of the joists provides a stable support frame for the installation of the precast structure.

[0097] The first preform 100 and the second preform 200 (and the optional third preform) are attached to the keel on the gypsum substrate by their mounting structure. After initial fixing with bolts, three-dimensional fine adjustment is performed to ensure that the first arc surface 101, the second arc surface 202 (and the third arc surface) are located on the same arc surface.

[0098] The use of gypsum board substrates offers several advantages: First, gypsum board, a commonly used base material in building decoration, features a smooth surface and ease of processing, providing a stable installation foundation for prefabricated components and reducing installation deviations caused by uneven walls. Second, gypsum board substrates exhibit good compatibility with GRG materials; their combination enhances the overall structural stability and reduces the risk of cracking or deformation due to temperature and humidity changes. Furthermore, gypsum board substrates are easy to cut and adjust on-site, adapting to archway openings of different sizes and shapes, thus improving the construction flexibility of prefabricated components.

[0099] During the joint treatment stage, the connection area between the preform and the gypsum substrate, as well as the mating edges between preforms (whether with or without gaps), can be seamlessly transitioned by filling with elastic sealant, applying anti-crack mesh tape, and sanding.

[0100] By combining factory-prefabricated components with standardized base layer processes for gypsum substrates, the prefabricated components disclosed herein can be rapidly assembled on-site, significantly improving construction efficiency while ensuring the continuity and consistency of decorative effects.
