Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a method and system for rapid customization and installation of irregular curved ceiling panels. Background Technology
[0002] Existing technologies have significant shortcomings in the digital modeling and segmentation planning stages of custom-designed irregular curved ceiling panels. They fail to utilize 3D digital scanning and surface reconstruction technologies to obtain accurate 3D surface data, relying solely on manual measurement and experience-based drawing. This results in low dimensional accuracy, poor surface reproduction, and an inability to accurately reflect the irregular characteristics of the installation area. Furthermore, they fail to combine 3D surface data with decorative parameters for scientific segmentation and joint planning, blindly segmenting according to fixed dimensions and ignoring the special characteristics of areas with high curvature variations. This leads to unreasonable segmentation and messy joints, affecting the decorative effect and increasing the difficulty of subsequent processing and installation, making it difficult to meet the customized needs of irregular curved ceiling panels.
[0003] Existing technologies have significant shortcomings in the processing and installation of irregularly shaped curved ceiling panels. They fail to accurately convert the segmented 3D data into 2D cutting data and perform CNC coding, relying solely on manual layout and cutting, resulting in large errors, significant material waste, and a lack of standardized processing instructions, leading to poor quality of the solid curved surface segments. Furthermore, the lack of dedicated forming control parameters based on geometric feature data, relying solely on general processing methods, makes it difficult to guarantee the morphological accuracy and stability of the curved surface segments. During installation, the absence of precise spatial positioning reference data, relying solely on manual visual inspection and experience for positioning, prevents sequential and precise assembly, resulting in low installation efficiency, uneven splicing gaps, and even structural instability, failing to meet the actual needs for rapid and high-quality installation of irregularly shaped curved ceiling panels.

[0069] Reference Figure 1 The diagram shown is a flowchart illustrating a method for rapid customization and installation of irregularly shaped curved ceiling panels according to an embodiment of the present invention. In this embodiment, the method for rapid customization and installation of irregularly shaped curved ceiling panels includes:
[0070] S1. Perform a three-dimensional digital scan of the irregular curved ceiling panel in the area to be installed to obtain the point cloud data of the irregular curved ceiling panel;
[0071] In this embodiment of the invention, a three-dimensional digital scan is performed on the irregular curved ceiling panel in the area to be installed to obtain the point cloud data of the irregular curved ceiling panel.
[0072] First, clean the area where the irregular curved ceiling panel will be installed, removing any debris that may obstruct the scanning line of sight or interfere with the scanning results. Ensure that the ceiling panel surface is free of dust, oil, or other attachments that may affect scanning accuracy, providing a clean and interference-free scanning environment for 3D digital scanning.
[0073] Select a 3D laser scanner that is compatible with scanning irregular curved surfaces. Adjust the scanning angle and mounting position of the scanner according to the size of the area to be installed and the complexity of the curved surface of the ceiling panel to ensure that the scanner can completely cover all surfaces of the irregular curved ceiling panel without any scanning blind spots.
[0074] When the 3D laser scanner is activated, the device emits a laser beam to illuminate the surface of the irregularly shaped curved ceiling panel. After the laser beam contacts the surface of the ceiling panel, it is reflected back to the scanner. The scanner's built-in receiver captures the reflected signal and records information such as the time difference between laser emission and reception and the propagation path.
[0075] Based on the relevant principles of laser propagation, the three-dimensional coordinates of the laser irradiation point in space are accurately calculated by analyzing the time difference and propagation path of the reflected signal. As the scanner continues to scan, a large number of three-dimensional coordinate points on the surface of the ceiling panel are continuously collected. These continuous three-dimensional coordinate points together constitute point cloud data that can completely characterize the shape and structure of the irregular curved ceiling panel.
[0076] The beneficial effects are that by scanning the installation area of irregularly shaped curved ceiling panels using 3D digital scanning technology, the three-dimensional spatial information of the ceiling panel surface can be comprehensively captured, covering core features such as shape contour, surface curvature, and key dimensions, forming a massive continuous point cloud data composed of three-dimensional coordinate points. This method replaces traditional manual measurement, avoiding subjective errors and measurement blind spots caused by manual operation, and significantly improving the comprehensiveness and accuracy of data collection.
[0077] Point cloud data fully restores the true shape of the irregular curved surface in the area to be installed, providing high-precision and high-density basic data support for subsequent surface reconstruction. This ensures that the subsequently generated 3D curved surface data can accurately match the actual installation requirements, guaranteeing the consistency and adaptability of the customized and installed irregular curved ceiling panels from the source.
[0078] S2. Perform surface reconstruction on the point cloud data to obtain the three-dimensional surface data of the irregular curved ceiling panel;
[0079] In this embodiment of the invention, the step of reconstructing the point cloud data to obtain the three-dimensional surface data of the irregular curved ceiling panel includes:
[0080] The point cloud data is denoised to obtain optimized point cloud data for the irregular curved ceiling panel;
[0081] Geometric feature extraction is performed based on the optimized point cloud data to obtain the feature line data of the irregular curved ceiling panel;
[0082] Using the feature line data as constraints, surface patch fitting and stitching are performed on the optimized point cloud data to obtain the preliminary surface data representation of the irregular curved ceiling panel;
[0083] The matching degree of the preliminary surface data representation and the optimized point cloud data is verified, and the preliminary surface data representation is smoothed and optimized according to the verification result to obtain the three-dimensional surface data of the irregular curved ceiling panel.
[0084] A point cloud data denoising framework was constructed based on the shape characteristics of irregular curved ceiling panels and the distribution patterns of point cloud data. This framework identifies isolated and discrete points that deviate from the normal distribution range, resulting in noise data often caused by environmental interference and equipment errors. A neighborhood point filtering and comparison method is used to analyze the spatial relationship between each data point and its surrounding neighbors, determining whether it conforms to the continuous distribution characteristics of the curved ceiling panel surface. Data points identified as noise are removed, retaining only the valid data that accurately reflects the surface morphology of the ceiling panel, thus obtaining optimized point cloud data for the irregular curved ceiling panel.
[0085] Based on the spatial distribution characteristics of optimized point cloud data, a geometric feature recognition method is used to focus on analyzing key geometric information such as contour boundaries, curvature abrupt change regions, and surface intersection lines presented by the concentrated data points. By sorting out the connection relationships and distribution patterns of these key information, lines that can outline the overall shape and local details of the irregular curved ceiling panel are extracted. These lines can accurately reflect the key morphological changes of the ceiling panel surface, forming the feature line data of the irregular curved ceiling panel.
[0086] Using the extracted feature line data as the core constraint, the surface range, morphological trend, and connection relationships defined by the feature lines are clearly defined to ensure that the surface reconstruction process does not deviate from the actual shape of the ceiling panel. A surface patch fitting method is employed to segment the optimized point cloud data into regions divided by the feature lines. For each region's data points, a local surface patch that fits the data distribution is constructed, ensuring that each surface patch accurately matches the surface shape of its corresponding region. Subsequently, following the connection logic of the feature lines, the local surface patches are seamlessly stitched together, ensuring smooth transitions and tight connections between adjacent surface patches, forming the initial surface data representation of the irregularly shaped ceiling panel.
[0087] A matching verification system was established, comparing the preliminary surface data representation with the optimized point cloud data point by point. The deviation values of each point on the preliminary surface data and the corresponding spatial positions in the optimized point cloud data were calculated to comprehensively evaluate the degree of consistency between the two. Based on the verification results, for areas where the deviation exceeds a reasonable range, a surface smoothing optimization method was adopted. By adjusting the control parameters of the surface, the curvature changes and shape trends of the surface were corrected, so that the surface could not only conform to the actual shape reflected by the optimized point cloud data, but also ensure the smoothness and continuity of the overall surface, ultimately obtaining the three-dimensional surface data of the irregular curved ceiling panel.
[0088] The beneficial effects are as follows: Point cloud data acquisition is easily affected by scanning environment interference and equipment accuracy errors, resulting in the inclusion of noisy data such as isolated and discrete points. This noise can lead to morphological distortion in subsequent surface reconstruction. By constructing a denoising framework based on the shape characteristics of irregular curved ceiling panels and the distribution patterns of point cloud data, and employing a neighbor point screening and comparison method, the spatial positional relationship between each data point and its surrounding neighboring points is analyzed to determine whether it conforms to the continuous distribution characteristics of the curved surface. Noisy data is removed, and valid data is retained, resulting in optimized point cloud data. This effectively improves the purity and accuracy of point cloud data, providing a high-quality data foundation for subsequent geometric feature extraction and surface fitting, and avoiding surface reconstruction deviations caused by noise interference.
[0089] Optimized point cloud data contains a massive number of discrete 3D coordinate points, which are inefficient to use directly for surface reconstruction and difficult to control the core shape. Based on the spatial distribution characteristics of optimized point cloud data, a geometric feature recognition method is used to analyze key information such as contour boundaries, curvature abrupt change regions, and surface intersection lines in the data point set. The connection relationships and distribution patterns of these information are analyzed to extract feature line data that can outline the overall shape contour and local details of the ceiling panel. This data accurately reflects the key morphological changes of the ceiling panel surface, providing clear morphological constraints for subsequent surface reconstruction, ensuring that the reconstructed surface conforms to the actual shape characteristics and avoiding morphological deviation problems.
[0090] Using feature line data as the core constraint, the scope, morphological trend, and connection relationships of the surface reconstruction are clearly defined to avoid the reconstruction process deviating from the actual shape of the ceiling panel. The optimized point cloud data is divided into regions according to feature lines. A surface patch fitting method is used to construct local surface patches for each region that fit the data distribution, ensuring that each surface patch accurately matches the surface shape of its corresponding region. The local surface patches are seamlessly stitched together according to the feature line connection logic, ensuring smooth transitions and tight connections between adjacent surface patches, forming a preliminary surface data representation. This achieves the transformation from discrete point clouds to continuous surfaces, initially restoring the overall shape of the irregular curved ceiling panel and laying the foundation for subsequent optimization processing.
[0091] A matching verification system was established, comparing the initial surface data representation with the optimized point cloud data point by point. The deviation values of corresponding spatial locations were calculated to comprehensively assess the degree of agreement and accurately locate areas where the deviation exceeded a reasonable range. For these areas, a surface smoothing optimization method was employed to adjust surface control parameters, correct curvature changes and shape trends, ensuring that the surface both closely matches the actual shape reflected in the optimized point cloud data and maintains the overall smoothness and continuity of the surface. The resulting 3D surface data possesses both high precision and good shape consistency, capable of completely and accurately reproducing the true shape of irregularly shaped ceiling panels, providing reliable data support for subsequent segmentation planning, processing, and manufacturing.
[0092] S3. Based on the three-dimensional curved surface data, and combined with the preset decoration parameters, the block division and splicing seam planning are carried out to generate the ceiling block logic scheme of the irregular curved surface ceiling panel;
[0093] In this embodiment of the invention, the step of generating a ceiling block logic scheme for the irregular curved ceiling panel based on the three-dimensional curved surface data and combined with preset decorative parameters for segmentation and splicing seam planning includes:
[0094] Curvature analysis is performed on the three-dimensional surface data, and the high curvature variation region of the irregular curved ceiling panel is identified to generate the initial geometric block boundary line of the irregular curved ceiling panel;
[0095] The initial geometric block boundary lines are matched and verified with the preset decoration parameters;
[0096] Based on the matching and verification results, the initial geometric block boundary lines are optimized and reorganized to obtain the optimized block joint planning data of the irregular curved ceiling panel;
[0097] Based on the optimized segmented joint planning data, and by integrating the segmented geometric information, splicing relationship and identification information of the irregular curved ceiling panel, a logical scheme for the ceiling block of the irregular curved ceiling panel is generated.
[0098] This study delves into the morphology of irregularly shaped ceiling panels represented by 3D surface data. By analyzing the changes in curvature across different regions of the surface, it identifies areas with abrupt fluctuations in curvature and significant morphological transitions—these are the high-curvature variation regions. Based on the distribution, morphological characteristics, and curvature transition patterns of these high-curvature variation regions, lines are delineated to distinguish areas with different curvature characteristics. These lines precisely separate areas of gentle and abrupt curvature changes on the ceiling panel, forming the initial geometric boundary lines for the irregularly shaped ceiling panels.
[0099] The preset decorative parameters are formulated based on the ceiling decoration design requirements, construction process requirements, aesthetic standards, and material characteristics, covering key aspects such as the size range of sections, joint width, joint style, and symmetry of sections. The size, shape, and joint location of the sections divided by the initial geometric boundary lines are compared and checked one by one with the preset decorative parameters to determine whether the sections meet the size requirements, whether the joint style matches the design standards, and whether the overall section layout meets aesthetic requirements, thus comprehensively verifying the compatibility between the initial sections and the decorative parameters.
[0100] Based on the matching and verification results, adjustments are made to the parts of the initial geometric block boundary lines that do not match the decorative parameters. If the block size exceeds the preset range, the boundary lines are shrunk or expanded to adjust the block size; if the joint position conflicts with the decorative design, the boundary lines are shifted or reconstructed to optimize the joint layout; if the block shape affects construction or aesthetics, adjacent block boundary lines are split or merged to improve the block shape. Through optimization and reorganization operations such as splitting, merging, shifting, and reconstructing the boundary lines, it is ensured that the blocks and joints not only meet the decorative parameter requirements but also adapt to the curved shape of the ceiling panel, resulting in optimized block joint planning data for irregular curved ceiling panels.
[0101] Collect and optimize the block joint planning data, including the number of blocks, the three-dimensional geometry of each block, and its spatial location. Clarify the splicing sequence, connection method, and joint alignment requirements between blocks, and assign a unique identification mark to each block to distinguish different areas. Systematically integrate this block geometry information, splicing relationships, and identification information, organizing it into a complete scheme framework in a logical and structured manner. Define the construction scope, splicing details, and identification specifications for each block, generating a logical scheme for irregular curved ceiling panels that can directly guide ceiling construction.
[0102] The beneficial effects are that the 3D surface data fully characterizes the shape of the irregular curved ceiling panel. By analyzing its curvature, it is possible to accurately capture high curvature change areas where the curvature changes drastically. These areas are key transition points in the ceiling panel's shape. By delineating the initial geometric segmentation boundaries based on their distribution range, morphological characteristics, and the curvature transition rules of adjacent areas, scientific segmentation according to the natural shape of the surface can be achieved. This avoids the problem of traditional fixed-size segmentation ignoring surface features, ensuring that the initial segmentation can adapt to the irregular structure of the ceiling panel, laying a practical foundation for subsequent splicing seam planning.
[0103] The preset decoration parameters integrate ceiling decoration design requirements, construction process requirements, aesthetic standards, and material characteristics, clearly defining key requirements such as the range of segment sizes, joint width, and joint style. By comparing and verifying the segment size, shape, and joint location corresponding to the initial geometric segment boundary lines with the decoration parameters one by one, the suitability of the initial segments in terms of decorative effect and construction feasibility can be comprehensively verified. Problems such as excessive segment size and inconsistent joint styles can be identified in a timely manner, avoiding unsatisfactory decorative effects or construction difficulties after subsequent segment processing and installation.
[0104] Based on the matching and verification results, targeted adjustments were made to address any unreasonable aspects of the initial geometric segment boundary lines. This involved adjusting the segment size by shrinking or expanding the boundary lines, optimizing the joint layout by translating or reconstructing the boundary lines, and improving the segment shape by splitting or merging the boundary lines. This ensured that the segments and joints met both decorative parameter requirements and adapted to the curved surface of the ceiling panel. The resulting optimized segment joint planning data clarified a scientifically sound segmentation method and splicing joint arrangement, making the segments easy to manufacture while ensuring the overall aesthetics and structural stability after splicing.
[0105] The process involves collecting and optimizing the geometric information of each segment from the segmented joint planning data, clarifying the three-dimensional shape and spatial location of each segment; outlining the splicing sequence and connection methods between segments; and assigning a unique identifier to each segment to distinguish different areas. This information is then systematically integrated in a logical and structured manner to form a complete ceiling segment logic scheme, clearly defining the construction scope, splicing details, and identification specifications for each segment. This scheme provides a unified and clear guiding basis for subsequent two-dimensional material cutting, processing and manufacturing, and sequential assembly, ensuring smooth transitions between stages and improving the overall efficiency of custom installation of irregularly shaped curved ceiling panels.
[0106] The complete ceiling block logic scheme clearly defines the construction scope, splicing details, and labeling specifications for each block. This scheme provides a unified and clear guideline for subsequent two-dimensional material cutting, processing and manufacturing, and serialized assembly, ensuring smooth connection between each stage and improving the overall efficiency of custom installation of irregular curved ceiling panels.

[0113] The two-dimensional blanking data is fused and compiled with the processing parameter set corresponding to the process identifier to obtain the processing instructions for the irregular curved ceiling panel.
[0114] Detailed information on all curved surface blocks in the ceiling block logic scheme is retrieved, and the three-dimensional geometric data of each block is extracted. This data fully characterizes the block's spatial shape, size, surface curvature, and other core morphological features. Simultaneously, material properties associated with each block are collected, including physical properties such as elasticity, toughness, and shrinkage rate, as well as process identifiers. These process identifiers clearly define the corresponding processing method, splicing requirements, surface treatment standards, and other key process information, ensuring comprehensive acquisition of the basic information required for subsequent data conversion.
[0115] A thorough analysis of the inherent geometric properties of surfaces in 3D geometric data is conducted, including the surface curvature distribution, extension direction, and contour features. Based on these properties, a neutral mapping reference direction is determined that minimizes surface unfolding deformation. This direction must conform to the natural extension trend of the surface to avoid excessive stretching or compression during unfolding, ensuring that the morphological characteristics of the original surface are preserved to the greatest extent when mapping 3D data to a 2D plane, providing a stable reference for subsequent parametric mapping.
[0116] Using a defined neutral mapping reference direction, a mapping relationship between 3D data and a 2D plane is established. The spatial 3D coordinates of the surface blocks are transformed into 2D plane coordinates one by one according to the mapping rules. During the mapping process, the geometric constraints of the surface are strictly followed to ensure that the relative positions of each point on the 2D plane are consistent with their corresponding positions on the 3D surface. Through this parametric mapping method, the contour shape of the surface blocks is completely restored, and the initial 2D unfolded contour of the irregular curved ceiling panel is obtained.
[0117] Based on the shrinkage rate, elastic deformation, and other characteristics of different materials, combined with the processing precision and splicing gaps required by the process specifications, the deformation errors that may occur during the processing and forming of curved surface segments are calculated. For the initial two-dimensional unfolded contour, reverse compensation adjustments are made according to the calculated deformation errors. For example, for easily shrinking materials, the contour dimensions are appropriately enlarged; for splicing points, gaps required by the process are reserved. Through this deformation compensation process, accurate two-dimensional contour data that precisely matches the actual processing requirements is obtained. This accurate two-dimensional contour data is combined with preset layout boundary information to clarify the placement position, direction, and spacing of the contour on the material sheet, integrating them to form the two-dimensional cutting data for the irregular curved ceiling panel.
[0118] The system retrieves the processing parameter set corresponding to the process identifier. This parameter set includes all key parameters related to the processing, such as cutting speed, tool type, processing sequence, and accuracy requirements. The contour dimensions and positional information from the 2D blanking data are systematically integrated with these processing parameters. The data is then compiled and converted according to the coding rules recognizable by CNC machining equipment. This transforms the scattered geometric information and process parameters into instruction codes that the equipment can directly execute. Each code corresponds to a specific processing operation, ultimately forming complete and standardized processing instructions for the irregular curved ceiling panel.
[0119] The beneficial effects are as follows: It comprehensively retrieves the core information of the curved surface blocks in the logical scheme of the ceiling area; the three-dimensional geometric data fully presents the spatial shape, size specifications, and curvature of the blocks; the material properties clearly define the physical characteristics of the material, such as elasticity and shrinkage rate; and the process identification defines key specifications such as processing methods and splicing requirements. These three elements work together to provide complete basic information required for data conversion and processing, avoiding subsequent material cutting deviations or processing compatibility issues due to missing information, thus laying a solid foundation for the generation of two-dimensional material cutting data and the compilation of processing instructions.
[0120] By deeply analyzing the inherent properties of surfaces in 3D geometric data, including curvature distribution and extension trends, a neutral mapping reference direction that minimizes unfolding deformation is determined. This direction conforms to the natural extension law of the surface, effectively avoiding excessive stretching or compression during the conversion of 3D data to 2D, ensuring that key morphological features of the surface are not lost during the mapping process, providing a stable and accurate directional reference for subsequent parametric mapping, and ensuring the consistency of the 2D unfolded contour with the original 3D surface.
[0121] Using the neutral mapping reference direction, a precise correspondence between three-dimensional coordinates and two-dimensional planar coordinates is established. Following mapping rules, the spatial three-dimensional data of the surface blocks is transformed into two-dimensional data one by one. The mapping process strictly adheres to surface geometric constraints, ensuring that the relative positions of each point on the two-dimensional plane perfectly match those on the three-dimensional surface, completely restoring the contour shape of the blocks. The generated initial two-dimensional unfolded contour provides a precise basic template for subsequent deformation compensation.
[0122] By combining the shrinkage and elastic deformation characteristics of different materials with the processing precision and splicing gaps required by the process specifications, the deformation errors that may occur during the segmentation and forming process are calculated. A reverse compensation adjustment is performed on the initial two-dimensional unfolded contour to ensure that the final accurate two-dimensional contour data can offset the deformation effects and conform to actual processing requirements. This data is integrated with the layout boundary information to clarify the placement position and spacing of the contour on the material sheet. The resulting two-dimensional blanking data ensures dimensional accuracy while optimizing material utilization and reducing waste.
[0123] The system retrieves the processing parameter set corresponding to the process identifier, covering key operational information such as cutting speed, tool type, and processing sequence, and integrates it with the contour dimensions and position information in the 2D blanking data. Following the coding rules recognizable by CNC machining equipment, it compiles and converts the scattered geometric information and process parameters into standardized instruction codes, with each code corresponding to a specific processing operation. The generated processing instructions are standardized and precise, and can be directly executed by the equipment, avoiding subjective errors from manual operation, ensuring the processing quality and efficiency of solid surface segmentation, and achieving seamless integration from data to processing.
[0124] S5. Based on the geometric feature data of the curved surface blocks in the ceiling block logic scheme, generate the forming control parameters of the irregular curved surface ceiling panel, and perform shape transformation on the blank of the irregular curved surface ceiling panel based on the forming control parameters and the processing instructions to obtain the solid curved surface blocks of the irregular curved surface ceiling panel.
[0125] In this embodiment of the invention, generating the forming control parameters of the irregular curved ceiling panel based on the geometric feature data of the curved surface blocks in the ceiling block logic scheme includes:
[0126] The logic scheme of the suspended ceiling block is analyzed to obtain the geometric feature data of the curved surface blocks and the associated material identifiers;
[0127] The geometric feature data is classified to obtain the key geometric elements of the geometric feature data;
[0128] Based on the material identifier, the corresponding material mechanical property data is obtained, and the material mechanical property data is coupled with the key geometric elements to obtain the preliminary forming control parameter set of the irregular curved ceiling panel;
[0129] The preliminary forming control parameter set is matched and optimized with the historical process records in the historical forming process database of the irregular curved ceiling panel to obtain the forming control parameters of the irregular curved ceiling panel.
[0130] The process of transforming the blank of the irregular curved ceiling panel based on the forming control parameters and the processing instructions to obtain the solid curved surface blocks of the irregular curved ceiling panel includes:
[0131] Based on the forming control parameters, the blank of the irregular curved ceiling panel is adapted to the process to obtain a parameterized blank to be converted;
[0132] Based on the processing instructions, the blank to be converted is subjected to two-dimensional contour separation to obtain the two-dimensional contour separated blank of the irregular curved ceiling panel;
[0133] Based on the forming control parameters, the two-dimensional contour separation blank is subjected to three-dimensional morphology gradient forming processing to obtain the transition blank of the irregular curved ceiling panel;
[0134] The transitional blank is subjected to stability treatment to obtain the solid curved surface blocks of the irregular curved ceiling panel.
[0135] This study delves into the complete logical scheme of the ceiling blocks, precisely extracting the geometric feature data of each curved surface segment. This data encompasses core geometric information such as the curvature, contour shape, dimensions, and surface arc variations of the curved surface segments. Simultaneously, it obtains material identifiers corresponding to each curved surface segment, clearly identifying the specific material used for that segment. This provides a direct basis for subsequently obtaining material-related attribute data, ensuring a comprehensive understanding of the fundamental information required to generate forming control parameters.
[0136] Based on the differences in the attributes of geometric feature data and their degree of influence on the forming process, a feature classification standard is established to divide the geometric feature data into different categories. Key geometric elements that play a decisive role in the forming accuracy and difficulty of irregular curved ceiling panels are identified. These elements include the region corresponding to the maximum curvature value of the surface, the turning points of complex contours, and key sections with high dimensional accuracy requirements. By focusing on the core elements through classification, a targeted geometric basis is provided for subsequent coupled analysis.
[0137] Based on the extracted material identifiers, corresponding material mechanical property data are retrieved from a pre-defined material property database. This data includes key mechanical parameters such as the material's elastic modulus, yield strength, elongation, and hardness, comprehensively reflecting the material's deformation patterns and mechanical properties under stress. These material mechanical property data are then systematically coupled with selected key geometric elements to analyze the forming response of materials with different mechanical properties under corresponding geometric features. Examples include the tensile deformation capacity of materials in high-curvature regions and the plastic flow trend of materials in complex contours. Based on the analysis results, core control items affecting forming are determined, forming a preliminary set of forming control parameters for irregular curved ceiling panels.
[0138] A historical forming process database for irregularly shaped curved ceiling panels was constructed. This database stores historical process records, including process parameters, forming effects, and problem records, for ceiling panels made of similar materials and with similar geometric features. The preliminary forming control parameter set was compared one by one with the historical process records in the database. Historical records with high similarity in material type and geometric features were selected, and mature process parameters and optimization experience were referenced to adjust various parameters in the preliminary forming control parameter set. For example, if a certain pressure parameter showed good forming results for similar high-curvature areas in the historical records, this parameter was used to optimize the current preliminary parameters, ultimately obtaining forming control parameters suitable for the current irregularly shaped curved ceiling panel.
[0139] Obtain the process adaptation requirements from the forming control parameters, including key information such as pretreatment standards for the blank, temperature control range, and stress mode. Process the original blank of the irregular curved ceiling panel according to these requirements. For example, adjust the ambient temperature of the blank according to the temperature control requirements to ensure the blank is in a suitable forming state; remove surface impurities and trim the initial dimensions of the blank according to the pretreatment standards, so that the physical state and initial shape of the blank fully conform to the adaptation specifications of the forming control parameters, resulting in a parameterized blank to be converted.
[0140] The core information contained in the processing instructions, such as the two-dimensional contour data, cutting path, and separation method, is analyzed and transformed into operational logic that can be executed by the billet processing equipment. The processing equipment is started, and the parameterized billet to be converted is precisely cut according to the preset cutting path and separation method. The excess parts of the billet are removed, and only the main body of the billet that perfectly matches the two-dimensional contour data is retained, so as to achieve a precise correspondence between the billet and the two-dimensional contour, and obtain the two-dimensional contour separated billet of the irregular curved ceiling panel.
[0141] Guided by forming control parameters, key parameters such as the rate of three-dimensional morphological transition, stress intensity, and deformation direction are clearly defined. These parameters are based on the material mechanical properties of the blank and the target three-dimensional curved surface morphology. A controlled external force is applied to the two-dimensional contour-separated blank using specialized forming equipment. Simultaneously, the direction and intensity of the external force are adjusted according to a preset rate, guiding the blank from a two-dimensional planar shape to a three-dimensional curved surface. The deformation state of the blank is monitored in real time during the transition process to ensure that each deformation step meets the forming control parameter requirements, avoiding excessive or insufficient deformation, thus obtaining a transitional blank for the irregular curved ceiling panel.
[0142] A stability treatment system was established, encompassing key aspects such as deformation fixation, stress relief, and surface finishing. The transitional blank undergoes deformation fixation treatment, employing specialized fixtures or curing processes to maintain its three-dimensional curved surface shape and prevent springback deformation during subsequent processing. Internal stresses generated during the forming process are eliminated through heat treatment or vibration treatment, preventing stress concentration that could lead to cracking or deformation. Finally, the blank surface is finished to remove burrs, scratches, and other defects generated during forming, ensuring a smooth surface and stable shape, resulting in solid curved surface blocks of the irregularly shaped ceiling panel.
[0143] The beneficial effects include a comprehensive understanding of the ceiling block logic scheme, precise extraction of geometric feature data for each curved surface block, and complete coverage of core geometric information such as the curvature, contour shape, size specifications, and surface arc variations of the block. Simultaneously, it obtains material identifiers corresponding to each curved surface block. The geometric feature data provides the morphological basis for forming control parameters, and the material identifiers clarify the types of materials used in the blocks. Together, they constitute the foundational information for generating forming control parameters, ensuring that subsequent parameter generation accurately adapts to the block shape and material properties, and avoiding a disconnect between parameters and actual requirements due to missing information.
[0144] Based on the degree of influence of geometric feature data on the forming process, a clear feature classification standard is established to categorize and organize complex geometric feature data. Key geometric elements that play a decisive role in forming accuracy and difficulty are selected, such as high-curvature areas, complex contour transitions, and critical sections requiring high precision. By focusing on core influencing factors and reducing interference from irrelevant information, subsequent coupling analysis becomes more targeted, laying a focused foundation for generating accurate forming control parameters.
[0145] Based on the material identifier, the corresponding material mechanical property data is retrieved from a pre-set material property database, covering key parameters such as elastic modulus, yield strength, and elongation, to comprehensively understand the deformation law of the material during the stress process. The material mechanical property data is systematically coupled with key geometric elements for analysis, to deeply explore the forming response of materials with different mechanical properties under corresponding geometric features, such as the tensile deformation capacity of materials in high curvature regions and the plastic flow trend of materials in complex contours. Based on the analysis results, the core control items affecting forming are determined, forming a preliminary set of forming control parameters to ensure that the parameters can simultaneously adapt to material properties and geometric shape.
[0146] By leveraging a historical forming process database for irregularly shaped curved ceiling panels, which stores mature process parameters, forming effects, and problem records for similar materials and geometric features, the initial forming control parameter set is compared one by one with the historical process records in the database. Records with high similarity in material type and geometric features are selected, and optimization experience verified in practice is used to adjust and improve the initial parameters. Through this matching optimization, unreasonable parameters are eliminated and deviations are corrected, making the final forming control parameters more reliable and practical, ensuring the forming quality and stability of solid curved surface blocks.
[0147] Forming control parameters include key process requirements such as blank pretreatment standards, temperature control range, and stress methods. These requirements are based on the geometric features of the curved surface segments and material properties. The original blank is processed according to these requirements, such as adjusting the ambient temperature to suit the forming requirements, removing surface impurities, and trimming the initial dimensions to conform to process specifications. This ensures that the physical state and initial shape of the blank perfectly match the subsequent processing and forming requirements, resulting in a parameterized blank for conversion. This provides a standardized and highly adaptable base blank for subsequent two-dimensional contour separation and three-dimensional morphology forming, avoiding processing deviations or forming failures caused by incompatible blank states.
[0148] The processing instructions clearly define core information such as 2D contour data, cutting paths, and separation methods. This information is precisely converted from the logical scheme of the ceiling blocks. According to the processing instructions, specialized processing equipment precisely cuts the parameterized blank to be converted, strictly following the preset cutting path to remove excess parts, retaining only the main body of the blank that perfectly matches the 2D contour data. This achieves a precise correspondence between the blank and the 2D contour, resulting in a 2D contour-separated blank. This step precisely defines the 2D shape of the blank, delineating the basic contour range for subsequent 3D morphological shaping, ensuring that the formed block contours are consistent with the design requirements.
[0149] The information is precisely converted from the logical scheme of the ceiling block. Following processing instructions, specialized processing equipment precisely cuts the parameterized blank to be converted, strictly adhering to the preset cutting path to remove excess parts, retaining only the main body of the blank that perfectly matches the two-dimensional contour data. This achieves a precise correspondence between the blank and the two-dimensional contour, resulting in a two-dimensional contour-separated blank. This step precisely defines the two-dimensional shape of the blank, delineating the basic contour range for subsequent three-dimensional morphological forming, ensuring that the formed block contours are consistent with the design requirements.
[0150] A stability treatment system encompassing deformation fixation, stress relief, and surface finishing is established to address potential issues such as springback deformation, internal stress, and surface defects in transitional blanks. Specialized fixtures or curing processes are used to fix the three-dimensional curved surface shape. Internal stress generated during forming is eliminated through heat treatment or vibration treatment. Surface burrs, scratches, and other defects are repaired to ensure a smooth surface and stable shape, resulting in solid curved surface segments. The final solid curved surface segments possess both precise dimensions and excellent structural stability, directly meeting subsequent splicing and installation requirements and ensuring the overall installation quality of irregularly shaped curved ceiling panels.
[0151] S6. Generate spatial positioning reference data for the irregular curved ceiling panel based on the boundary planning in the ceiling block logic scheme;
[0152] In this embodiment of the invention, generating spatial positioning reference data for the irregular curved ceiling panel based on the boundary planning in the ceiling block logic scheme includes:
[0153] Based on the boundary planning in the above ceiling block logic scheme, extract the edge contour data of the solid surface block;
[0154] The edge contour data is spliced to identify the splicing edge, thereby obtaining the splicing boundary data of the solid surface blocks;
[0155] Based on the splicing boundary data, spatial reference lines are used to divide the splicing boundary of the solid surface blocks to obtain the spatial positioning reference lines of the solid surface blocks.
[0156] The logic scheme of the suspended ceiling block is analyzed to obtain the center line information of the main control keel in the irregular curved ceiling panel, and the center line information is established as the spatial reference axis of the irregular curved ceiling panel;
[0157] Based on the geometric relationship between the splicing boundary data corresponding to the spatial positioning reference line and the spatial reference axis, the three-dimensional spatial coordinates of the reference points on the spatial positioning reference line are calculated to obtain the spatial positioning reference data of the spatial positioning reference line.
[0158] The formula for calculating the three-dimensional spatial coordinates is: ;
[0159] In the formula, Starting from the starting point The three-dimensional spatial coordinates of a reference point The coordinates of the starting point are determined based on the spatial reference axis and the starting point of the current splicing boundary. Reference point number, The preset standard width of the decorative panel The preset seam width, For from the first The reference point points to the first The unit tangent vector of each reference point.
[0160] A thorough study of the boundary planning content in the ceiling block logic scheme is conducted to clarify the spatial range, edge definition standards, and connection requirements of the solid curved surface blocks within the overall ceiling structure. Through 3D scanning or data analysis, complete data that outlines the edge morphology of the solid curved surface blocks is precisely extracted from their 3D models. This data includes key information such as the curve direction, turning points, and length dimensions of the block edges, forming the edge contour data of the solid curved surface blocks.
[0161] Based on the splicing design principles clearly defined in the ceiling block logic scheme, and combined with the morphological characteristics of the edge contour data, specific edge portions used for connection with other blocks in the solid surface blocks are identified. By analyzing the curvature changes, consistency of direction, and correspondence with adjacent blocks, non-sponging edges and splicing edges are distinguished. The contour data corresponding to the splicing edges are extracted and organized separately to obtain the splicing boundary data of the solid surface blocks, ensuring that this data can accurately reflect the geometric shape of the splicing area.
[0162] Based on the splicing boundary data, and considering the 3D spatial pose and splicing accuracy requirements of the solid surface blocks, spatial reference line division rules are formulated. According to these rules, key feature points, such as turning points, midpoints, and curvature extrema, are selected on the splicing boundary. By connecting these feature points, reference lines that traverse the splicing boundary are formed. These lines maintain a fixed geometric relationship with the splicing boundary, enabling precise positioning of the splicing boundary's spatial location, thus obtaining the spatial positioning reference lines for the solid surface blocks.
[0163] A comprehensive analysis of the ceiling panel layout logic was conducted to extract relevant design information for the main control keel, including its placement, extension direction, and installation height. Based on this information, the centerline of the main control keel was determined. This centerline reflects the overall orientation and spatial posture of the main control keel and serves as the core benchmark for the installation and positioning of the entire irregular curved ceiling panel. This centerline was formally established as the spatial reference axis for the irregular curved ceiling panel, providing a unified reference for the spatial positioning of all subsequent panels.
[0164] By analyzing the relative positional relationship between the splicing boundary data corresponding to the spatial positioning reference line and the spatial reference axis, including geometric features such as parallelism, perpendicularity, angle, and distance, a logical association between the two is established. Based on this association, the spatial position of each reference point on the spatial positioning reference line relative to the spatial reference axis is determined one by one. By clarifying the front-back, left-right, and up-down orientation of the reference points in three-dimensional space, the specific positional information of each reference point is accurately determined. By integrating the positional data of all reference points, the spatial positioning reference data of the spatial positioning reference line is obtained.
[0165] Starting from the starting point, the... The three-dimensional spatial coordinates of a reference point are the core result calculated by combining the coordinates of the starting point, the standard width of the decorative panel, the width of the splicing seam, and the unit tangent vector. This directly clarifies the specific location of the reference point in three-dimensional space and is a key component of spatial positioning reference data.
[0166] Based on the coordinates of the starting point determined by the spatial reference axis and the current splicing boundary, it is necessary to first clarify the three-dimensional position information of the spatial reference axis. This information comes from the analysis of the center line of the main control keel in the ceiling block logic scheme. Then, locate the starting point of the current splicing boundary, and combine it with the position of the spatial reference axis. By determining the relative orientation relationship between the two, the specific position of the starting point in three-dimensional space is accurately locked, forming the starting point coordinates.
[0167] The reference point number is a sequential identifier for reference points on the spatial positioning reference line. Starting from the starting point, the reference points are ordered in sequence, and each reference point has a unique number to distinguish reference points in different locations, ensuring that the order of reference points is not confused during the calculation process.
[0168] The preset standard width of the decorative panel is a fixed width value preset according to the design requirements, material specifications and decorative effect of the irregular curved ceiling panel. This width value clarifies the standard size of a single decorative panel and is an important basis for determining the spacing when calculating the coordinates of the reference point.
[0169] The preset joint width is a fixed value that takes into account the aesthetic requirements of the ceiling decoration, construction process standards, and the expansion and contraction characteristics of the materials. It is used to regulate the splicing gap between adjacent decorative panels and ensure the consistency and stability of the splice.
[0170] From the The reference point points to the first The unit tangent vector of the nth reference point needs to be determined first on the spatial positioning reference line. The first reference point and the first The positions of two reference points are determined, and the direction vector from the former to the latter is calculated based on the spatial relationship between the two points. This direction vector is then standardized to a length of one, forming a unit tangent vector. This vector clarifies the directional relationship between the two reference points.
[0171] The significance of this formula lies in its precise calculation of the three-dimensional spatial coordinates of each reference point on the spatial positioning reference line, providing a scientific basis for the installation positioning of irregularly shaped curved ceiling panels. The formula establishes a calculation benchmark through the starting point coordinates, determines the distance between reference points by combining the standard width of the decorative panel and the width of the splicing seam, clarifies the extension direction of the reference points using the unit tangent vector, and calculates the specific coordinates of each reference point sequentially through a step-by-step accumulation method. This ensures that the coordinates of all reference points not only meet the decorative design requirements but also accurately reflect the spatial shape of the splicing boundary, providing a unified and precise reference standard for the installation positioning of solid curved surface segments, and guaranteeing the flatness and sealing of the overall installation of irregularly shaped curved ceiling panels.
[0172] The beneficial effects are that the boundary planning in the ceiling block logic scheme clearly defines the spatial range and edge definition standards of the solid surface blocks. Based on this planning, edge contour data is accurately extracted from the 3D model of the solid surface blocks, fully covering key information such as the curve direction, turning points, and length dimensions of the block edges. This data accurately reflects the edge morphology of the blocks, providing a precise basis for subsequent splicing boundary identification and spatial positioning reference line division, ensuring that subsequent positioning-related data completely matches the actual edge features of the blocks.
[0173] Based on the splicing design principles in the ceiling block logic scheme, the morphological characteristics of the edge contour data are analyzed. By judging the curvature changes, consistency of direction, and correspondence with adjacent blocks, non-sponge edges and splicing edges are accurately distinguished. The contour data corresponding to the splicing edges are extracted and organized separately to form splicing boundary data, clarifying the specific parts and geometric shapes used for connection between blocks. This provides focused core data for subsequent spatial reference line division and positioning coordinate calculation, avoiding interference from irrelevant edge data in positioning accuracy.
[0174] Based on the splicing boundary data, and considering the 3D spatial pose and splicing accuracy requirements of the solid surface blocks, scientific rules for dividing spatial reference lines were formulated. Key feature points such as turning points, midpoints, and curvature extrema were selected on the splicing boundary. By connecting these feature points, a spatial positioning reference line was formed that runs through the splicing boundary. This line maintains a fixed geometric relationship with the splicing boundary, enabling precise positioning of the boundary's spatial location. This provides a clear benchmark line for subsequent 3D spatial coordinate calculations, making the generation of positioning reference data more targeted and accurate.
[0175] A comprehensive analysis of the ceiling block logic scheme reveals core design information such as the layout, extension direction, and installation height of the main control keel, thereby determining its centerline. This centerline is established as the spatial reference axis, reflecting the overall orientation and spatial posture of the main control keel, providing a unified and fixed reference benchmark for the spatial positioning of all solid curved surface blocks. This avoids positioning deviations caused by inconsistent reference standards during the positioning process, ensuring consistency and correlation in the positioning data of each block, and laying the foundation for precise assembly of the entire ceiling.
[0176] A thorough analysis of the relative positional relationship between the splicing boundary data corresponding to the spatial positioning reference line and the spatial reference axis is conducted, including geometric features such as parallelism, perpendicularity, angle, and distance, to establish a clear logical correlation between the two. Based on this correlation, the three-dimensional spatial position of each reference point on the spatial positioning reference line relative to the spatial reference axis is determined one by one, accurately locking the specific orientation of each reference point and integrating them to form spatial positioning reference data. This data provides a precise spatial positioning basis for the serialized assembly of solid curved surface blocks, ensuring accurate alignment during block installation and significantly improving installation accuracy and splicing effect.
[0177] This formula establishes a unified calculation benchmark by starting point coordinates, clarifies the spacing between reference points by combining the standard width of the decorative panel and the width of the splicing seam, defines the extension direction of the reference points using unit tangent vectors, and accurately calculates the three-dimensional spatial coordinates of each reference point through a progressively accumulating logic. This ensures that each reference point on the spatial positioning reference line has a clear and unique spatial location identifier, completely eliminating the limitations of traditional positioning that relies on experience-based judgment, and guaranteeing the accuracy and consistency of reference point location calculations.
[0178] The pre-set standard width of the decorative panels conforms to the size design requirements of the ceiling decoration, and the pre-set splicing joint width conforms to the construction process specifications and material expansion and contraction characteristics. The combination of these two ensures that the spacing of the reference points satisfies both the uniformity of the decorative effect and the feasibility of splicing construction. The formula incorporates these core design and construction requirements into coordinate calculations, ensuring that the generated three-dimensional spatial coordinates can directly guide the actual installation, making the splicing of solid curved surface blocks both aesthetically pleasing and robust.
[0179] Each parameter in the formula has a clear origin and practical significance. The starting point coordinates are determined based on the spatial reference axis and the starting point of the splicing boundary. The unit tangent vector is derived from the spatial positional relationship between reference points. All parameters are mutually complementary and logically rigorous. The three-dimensional spatial coordinates calculated by this formula can accurately reflect the spatial morphology of the splicing boundary, providing high-quality core content for spatial positioning reference data and ensuring that the positioning reference data has reliable guiding value.
[0180] Based on the three-dimensional spatial coordinates obtained from the formula, complete spatial positioning reference data is formed, clearly defining the installation position and splicing relationship of each solid curved surface block. During the serialized assembly process, construction personnel can quickly locate the block position and adjust the block posture according to these precise coordinates, greatly reducing the error and time consumption of manual positioning, ensuring uniform splicing gaps between each block and overall flat installation, and improving the efficiency and quality of irregular curved ceiling panel installation.
[0181] S7. Based on the spatial positioning reference data, the irregular curved ceiling panels are assembled sequentially to complete the installation of the ceiling panels.
[0182] In this embodiment of the invention, the step of sequentially assembling the irregular curved ceiling panel based on the spatial positioning reference data to complete the installation of the ceiling panel includes:
[0183] Based on the spatial positioning reference data, the logical positional relationship of the solid surface blocks is analyzed to generate the assembly sequence instructions for the irregular curved ceiling panel;
[0184] Based on the assembly sequence instructions, the solid curved surface blocks are hoisted to obtain the preliminary positioning blocks of the irregular curved surface ceiling panel;
[0185] Based on the spatial coordinate set corresponding to the preliminary positioning block in the spatial positioning reference data, the spatial position of the preliminary positioning block is adjusted to obtain the precise positioning block of the irregular curved ceiling panel;
[0186] The precise positioning segment is temporarily connected and fixed to the irregular curved surface substrate to obtain the temporary fixed segment of the irregular curved surface ceiling panel;
[0187] The temporary fixing blocks are permanently connected and fixed to complete the installation of the irregular curved ceiling panel.
[0188] A thorough analysis of the spatial positioning reference data reveals the three-dimensional spatial coordinates, splicing boundary relationships, and identification information of each solid curved surface segment. This analysis clarifies the relative position, hierarchical structure, and splicing sequence requirements of each segment within the overall ceiling structure. Combining the construction process specifications, load-bearing distribution patterns, and ease of operation principles for ceiling installation, the installation sequence of each solid curved surface segment is determined. This sequence is then translated into clear and explicit operational instructions, which include key information such as the hoisting timing and installation location for each segment, generating assembly sequence instructions for the irregular curved ceiling panels.
[0189] According to the assembly sequence instructions, prepare suitable hoisting equipment and tools. Based on the weight, size, and spatial shape of the solid curved surface segment, select appropriate hoisting methods and hoisting point positions to ensure a smooth and safe hoisting process. Start the hoisting equipment, and operators, following the instructions, gradually hoist the corresponding solid curved surface segment to the preset installation area. During the hoisting process, observe the spatial posture of the segment in real time to avoid collisions with surrounding structures or other segments. Initially place the segment in an area close to the target installation position to obtain the preliminary positioning of the irregular curved ceiling panel.
[0190] A complete set of spatial coordinates corresponding to the initial positioning blocks is extracted from the spatial positioning reference data. This coordinate set clarifies the precise position, angle, and relative relationship of each block in three-dimensional space with adjacent blocks. Using professional positioning measurement tools, the actual spatial position of each initial positioning block is compared with the standard position in the coordinate set, detecting the offset and angular deviation of the blocks in the front-back, left-right, and up-down directions. By adjusting the position and angle of the hoisting equipment or using auxiliary support tools, the deviations are gradually corrected until the actual position of the block perfectly matches the standard coordinates, resulting in the precise positioning blocks of the irregular curved ceiling panel.
[0191] Prepare the necessary connectors and tools for temporary connection and fixation. The connectors must possess sufficient strength and stability to temporarily secure the precisely positioned sections. Based on the structural characteristics of the irregular curved surface substrate and the installation requirements of the precisely positioned sections, install temporary connectors, such as clips and clamps, at the connection points between the sections and the substrate. Ensure that the connectors are firmly attached to the connection surfaces without loosening or displacement. Through temporary connection and fixation, maintain the spatial position of the precisely positioned sections and prevent displacement during subsequent operations, thus obtaining the temporarily fixed sections of the irregular curved ceiling panel.
[0192] Select permanent connection materials that meet the strength and durability requirements of ceiling installation, such as specialized bolts, welding materials, and structural adhesives. Based on the connection structure between the temporary fixing sections and the irregular curved surface substrate, adopt the corresponding permanent connection method. For bolted connections, drill holes according to the preset diameter, insert bolts, and tighten them. For welded connections, precisely weld the connection points to ensure a strong weld. For adhesive connections, apply structural adhesive evenly and press it firmly into place. After connection, check the firmness and sealing of the connection points to ensure there is no risk of loosening or detachment, thus completing the installation of the irregular curved ceiling panel.
[0193] The beneficial effects are that the spatial positioning reference data includes the three-dimensional spatial coordinates, splicing boundary relationships, and identification information of each solid surface segment. Based on this data, the relative position, hierarchical structure, and splicing sequence requirements of each segment within the overall ceiling structure can be clearly identified. Combining the construction process specifications, load-bearing distribution patterns, and operational convenience principles for ceiling installation, a scientifically sound installation sequence is determined and transformed into assembly sequence instructions containing key information such as hoisting timing and installation location. These instructions provide clear operational guidance for subsequent hoisting and assembly, avoiding construction conflicts or structural instability caused by a chaotic installation sequence, and ensuring the orderly progress of the assembly process.
[0194] Based on the assembly sequence instructions, suitable hoisting equipment and tools are matched. The appropriate hoisting method and lifting point positions are determined according to the weight, size, and spatial shape of the solid curved surface blocks to ensure the stability and safety of the hoisting process. Following the instructions, operators precisely hoist the corresponding solid curved surface blocks to the preset installation area, observing the spatial posture of the blocks in real time and avoiding collision risks. The blocks are initially placed in an area close to the target installation position, achieving preliminary positioning. This step realizes the orderly transfer of blocks from the storage area to the installation area, laying the foundation for subsequent precise positioning and improving the efficiency and safety of the hoisting process.
[0195] A complete set of spatial coordinates corresponding to the initially positioned blocks is extracted from the spatial positioning reference data. This coordinate set clarifies the precise position, angle, and relative relationship of each block in three-dimensional space with adjacent blocks. Using professional positioning and measurement tools, the actual spatial position of each block is compared with the standard coordinates to accurately detect the offset and angular deviation in the front-back, left-right, and up-down directions. By adjusting the hoisting equipment or using auxiliary support tools, the deviations are gradually corrected until the actual position of the block perfectly matches the standard coordinates, resulting in precisely positioned blocks. This process completely eliminates the errors of traditional manual visual positioning, ensuring the accurate installation position of each block and guaranteeing the sealing and flatness of subsequent splicing.
[0196] Temporary connectors with sufficient strength and stability are selected. Based on the structural characteristics of the irregular curved substrate and the precise installation requirements of the segmented installation, the connectors are precisely installed at the connection points between the segments and the substrate. It is ensured that the connectors are firmly fitted to the connection surfaces without loosening or displacement. This temporary connection maintains the spatial position of the segments, preventing displacement during subsequent operations, thus temporarily fixing the segments. This step provides a stable foundation for permanent connection and fixation, avoiding segment displacement during subsequent operations and ensuring the continuity and stability of the installation process.
[0197] Permanent connection materials meeting the strength and durability standards required for ceiling installation are selected. Depending on the connection structure between the sections and the substrate, appropriate permanent connection methods such as bolting, welding, or bonding are employed. Strict quality control is maintained throughout the connection process to ensure bolts are securely tightened, welds are strong, or bonds are tight. After connection, a comprehensive inspection of the joints' firmness and sealing is conducted to eliminate any risk of loosening or detachment. Finally, the installation of the irregularly shaped curved ceiling panels is completed, forming a stable overall structure from the solid curved sections. This ensures both the long-term safety of the ceiling and the aesthetics and sealing of the joints.
