Description

Technical Field

[0001] This invention relates to the field of timber structure construction technology, and in particular to a prefabricated timber structure construction system. Background Technology

[0002] With the advancement of modern construction technology and the popularization of environmental protection concepts, prefabricated timber structures have been widely used in residential and commercial buildings due to their advantages such as being green and environmentally friendly, having a fast construction speed, and using renewable materials. Traditional timber structures mainly rely on on-site manual processing and assembly. This construction method is not only inefficient but also easily affected by factors such as weather and worker skills, resulting in inconsistent construction quality. In recent years, with the development of BIM technology and prefabricated component manufacturing processes, prefabricated timber structures have gradually achieved digital management from design to production, significantly improving construction efficiency and quality control.

[0003] Nevertheless, existing prefabricated timber structure construction systems still have many shortcomings, specifically in the following aspects:

[0004] While BIM software can be used for preliminary design and modeling in existing technologies, the accumulation of small errors between individual components or modules often leads to deviations in the overall structure during actual construction. This is because existing systems typically only focus on the splicing accuracy of the overall structure, neglecting the differences between component and module levels. If errors at the component level are not detected and corrected in time, they will be amplified during subsequent assembly, affecting the stability of the final overall structure. Furthermore, if errors at the module level are also not given sufficient attention, problems such as poor interface matching and positioning misalignment are likely to occur, posing significant challenges to subsequent on-site installation.

[0005] Therefore, there is an urgent need for a technical solution for a prefabricated timber structure building construction system. Summary of the Invention

[0038] Final Timber Structure Building Model Determination Unit: If the overall splicing accuracy value of the pre-built timber structure building model is greater than the average of the historical overall splicing accuracy values, then the current pre-built timber structure building model is retained and used as the final timber structure building model; if the overall splicing accuracy value of the pre-built timber structure building model is less than or equal to the average of the historical overall splicing accuracy values, then the current pre-built timber structure building model is adjusted until the final timber structure building model is obtained.

[0039] Furthermore, the adjustment of the currently pre-constructed timber structure building model includes:

[0040] The first and second splicing accuracy value extraction interfaces are used to extract the first splicing accuracy value and / or the second splicing accuracy value respectively based on the fact that the overall splicing accuracy value of the current pre-built wooden structure building model is less than or equal to the average of the historical overall splicing accuracy values.

[0041] First Difference Determination Interface: This interface is used to obtain each first difference value for adjacent wooden structure models within each group based on the extracted first splicing accuracy value, set a first allowable range for each first difference value, and determine whether each first difference value exceeds the first allowable range. The first difference value includes:

This effectively solves the problem of overall structural deviation caused by ignoring the error differences between different levels in existing technologies, significantly improving the matching degree between architectural design and actual construction and the construction quality. At the same time, the closed-loop optimization capability of this invention system enables it to have good scalability and application prospects, and is especially suitable for the field of modern timber structure buildings with a high degree of standardization and industrialization. Attached Figure Description

[0062] To more clearly illustrate the specific embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the specific embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0063] Figure 1 This is a frame diagram of a prefabricated timber structure building construction system provided in an embodiment of the present invention. Detailed Implementation

[0064] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0065] Example 1: As Figure 1 As shown, the present invention provides a prefabricated timber structure building construction system, comprising the following modules:

[0066] Design scheme determination module: used to determine the project requirements of the timber structure building, and to determine the preliminary design scheme of the timber structure building based on the project requirements; the preliminary design scheme includes a preset assembly sequence, as well as preset design parameters, etc.

[0067] It is worth noting that project requirements for timber-framed buildings refer to the design goals and functional requirements proposed in the early stages of timber-framed building design, based on a comprehensive consideration of factors such as the client, intended use, budget constraints, laws and regulations, and environmental impact. Specifically, these include, but are not limited to, the following: 1. Functional requirements, such as the main purpose of the building (e.g., residential, commercial, educational), and requirements for the internal spatial layout (room size, number, functional zoning, etc.); 2. Technical requirements, such as building safety performance requirements (e.g., seismic resistance level, fire protection standards), energy efficiency standards (e.g., thermal insulation performance, green building certification), and sustainability indicators (e.g., material selection, carbon footprint calculation); 3. Aesthetic requirements, such as architectural style (modern, traditional, mixed, etc.), and requirements for material texture and color matching; 4. Economic requirements, such as the total budget range of the project and cost control strategies (e.g., selection of prefabricated components, optimization of construction cycle); 5. Legal and regulatory requirements, such as compliance with local building codes, land use regulations, and other relevant legal requirements, as well as environmental protection and safety standards.

[0068] Based on the aforementioned project requirements, the first step should be data collection and analysis, followed by a conceptual design process. A preliminary design scheme should then be developed, ensuring it includes pre-defined design parameters and assembly sequences. Specifically: First, information on the project site's geographical conditions, climate characteristics, and cultural background should be collected, and relevant laws, regulations, and technical standards should be analyzed to ensure the design scheme complies with all necessary regulations. Next, based on the collected information and project requirements, multiple conceptual design schemes should be proposed, covering different design concepts and solutions. It is worth noting that during the conceptual design phase, key elements of the project requirements should be clearly defined, such as functional requirements, technical requirements, aesthetic requirements, economic requirements, and legal regulatory requirements. Following this, after completing the data collection and analysis and conceptual design process, the specific design parameters for each family of wooden components need to be determined based on the project requirements—the pre-defined design parameters. These pre-defined design parameters will directly affect the specific implementation details in subsequent design phases. Finally, the installation sequence of each component should be determined again based on the project requirements—the pre-defined assembly sequence—to improve construction efficiency and reduce on-site adjustments.

[0069] Building model building module: Connected to the design scheme determination module, it is used to obtain a pre-built wooden structure building model using BIM software based on the preliminary design scheme;

[0070] Timber Component Family Selection Unit: Used to select timber component families using BIM software based on the preliminary design scheme;

[0071] Timber structure model acquisition unit: used to perform parametric modeling of each family of timber components according to preset design parameters, and obtain each timber structure model;

[0072] It is worth noting that when parametrically modeling each family of timber components according to preset design parameters, the preset design parameters should be called first, including but not limited to length, width, height, etc. Then, a basic model library containing various typical families of timber components should be created using BIM software (such as Revit, Tekla Structures, etc.). Then, the corresponding preset design parameters should be loaded for each model to obtain each timber structure model.

[0073] Timber structure model grouping unit: used to group each timber structure model according to its assembly position;

[0074] It is worth noting that when grouping each timber structure model, the location of each major component (such as frame, roof, floor, etc.) should be identified according to the overall layout plan of the timber structure building. Based on this, all timber structure models should be divided into several logical groups, each group representing a set of all components in a specific area or system, in order to facilitate subsequent detailed design and construction organization planning.

[0075] Assembly Model Acquisition Unit: Used to virtually connect each timber structure model within each group to obtain each assembly model;

[0076] It is worth noting that when making virtual connections between each wooden structure model within each group, the actual physical connection methods between each wooden structure model (such as mortise and tenon joints, bolt fixing, etc.) should be simulated in the digital environment using virtual connectors (such as virtual screws, nails, glue, etc.) to form a complete assembly model.

[0077] Timber structure building model acquisition unit: used to virtually connect each assembly model to obtain a pre-built timber structure building model;

[0078] It is worth noting that when virtually connecting each assembly model as a whole, all the previously obtained assembly models should be treated as independent units and finally assembled in the virtual environment according to the overall architectural design intent. This virtual connection process usually involves setting up a global coordinate system, determining the relative positional relationship between each assembly model, and ensuring that they can be accurately combined together through virtual connectors (such as large mechanical connectors, support structures, etc.) to construct a pre-built wooden structure building model.

[0079] Accuracy Analysis Module: Connected to the building model construction module, it is used to analyze the splicing accuracy of the pre-built timber structure building model and adjust the pre-built timber structure building model according to the analysis results to obtain the final timber structure building model;

[0080] First splicing accuracy value analysis unit: used to calculate the first splicing accuracy value between each adjacent timber structure model within each group;

[0081] First geometric information extraction interface: used to extract the first geometric information of each adjacent wooden structure model in each group at the connection point before virtual connection. The first geometric information includes the first coordinate position, the first size and the first angle direction.

[0082] The first coordinate position is a three-dimensional coordinate; the first size includes the size in the length, width and height directions.

[0083] First calculation interface: used to calculate, based on first geometric information, the first ideal splicing deviation, the first ideal size difference, and the first ideal angle difference at the connection point before virtual connection for each adjacent wooden structure model in each group;

[0084] The formulas for calculating the first ideal splicing deviation, the first ideal size difference, and the first ideal angle difference at the connection point before virtual connection for each adjacent timber structure model within each group are as follows:

[0085]

[0086] ΔL ideal,ij =|L i -L j |;

[0087] ΔW ideal,ij =|W i -W j |;

[0088] ΔH ideal,ij =|H i -H j |;

[0089] Δθ ideal,ij =|θ i -θ j |;

[0090] In the formula, d ideal,ij ΔL represents the first ideal splicing deviation between the i-th and j-th adjacent timber structure models at the connection point before the virtual connection; ideal,ij ΔW ideal,ij ΔH ideal,ijBoth represent the first ideal size difference between the i-th and j-th adjacent timber structure models at the connection point before the virtual connection, where ΔL ideal,ij The first ideal length difference, ΔW ideal,ij The first ideal width difference, ΔH ideal,ij The first ideal height difference; Δθ ideal,ij x represents the difference in the first ideal angle between the i-th and j-th adjacent timber structure models at the connection point before the virtual connection; i y i z i The x-coordinate represents the coordinate position of the i-th timber structure model before the virtual connection, i.e., its three-dimensional coordinates; j y j z j L represents the coordinate position of the j-th timber structure model before the virtual connection, i.e., its three-dimensional coordinates; i W i H i and θ i L represents the length, width, height, and angular direction of the i-th wooden structure model before the virtual connection; j W j H j and θ j These represent the length, width, height, and angle of the j-th wooden structure model before the virtual connection.

[0091] The first virtual splicing interface is used to virtually splice each adjacent wooden structure model within each group according to a preset assembly sequence.

[0092] Second geometric information extraction interface: used to obtain the second geometric information of the connection point of each adjacent wooden structure model in each group after virtual splicing. The second geometric information includes the second coordinate position, the second size and the second angle direction.

[0093] The second calculation interface is used to calculate, based on the second geometric information, the first actual splicing deviation, the first actual size difference, and the first actual angle difference at the connection points of each adjacent wooden structure model within each group after virtual splicing.

[0094] The formulas for calculating the first actual splicing deviation, the first actual size difference, and the first actual angle difference at the connection points of adjacent wooden structure models within each group after virtual splicing are as follows:

[0095]

[0096] ΔL actual,ij =|L i ′-L j ′|;

[0097] ΔW actual,ij =|W i ′-W j ′|;

[0098] ΔH actual,ij =|H i ′-H j ′|;

[0099] Δθ actual,ij =|θ i ′-θ j ′|;

[0100] In the formula, d actual,ij ΔL represents the first actual splicing deviation at the connection point between the i-th and j-th adjacent timber structure models after virtual connection; actual,ij ΔW actual,ij ΔH actual,ij Both represent the first actual size difference between the i-th and j-th adjacent timber structure models at the connection point after virtual connection, where ΔL actual,ij The first actual length difference, ΔW actual,ij The first actual width difference, ΔH actual,ij This represents the first actual height difference; Δθ actual,ij x represents the first actual angle difference between the i-th and j-th adjacent timber structure models at the connection point after virtual connection; i ′、y i ′、z i ′ represents the coordinate position of the i-th timber structure model after virtual connection, i.e., its three-dimensional coordinates; x j ′、y j ′、z j ′ represents the coordinate position of the j-th timber structure model after virtual connection, i.e., its three-dimensional coordinates; L i ′、W i ′、H i ′ and θ i ′ represent the length, width, height, and angular direction of the i-th wooden structure model after virtual connection; L j ′、W j ′、H j ′ and θ j ′ represent the length, width, height, and angular direction of the j-th wooden structure model after virtual connection, respectively.

[0101] The first splicing accuracy value calculation interface is used to calculate the first splicing accuracy value between each adjacent wooden structure model in each group by combining the first ideal splicing deviation, the first ideal size difference, and the first ideal angle difference at the connection point of each adjacent wooden structure model in each group after virtual splicing, as well as the first actual splicing deviation, the first actual size difference, and the first actual angle difference at the connection point of each adjacent wooden structure model in each group.

[0102] The formula for calculating the first splicing accuracy value between each adjacent timber structure model within each group is as follows:

[0103]

[0104] In the formula, P1 ij d represents the first splicing accuracy value between the i-th and j-th adjacent timber structure models; actual,ij ΔL represents the first actual splicing deviation at the connection point between the i-th and j-th adjacent timber structure models after virtual connection; actual,ij ΔW actual,ij ΔH actual,ij Both represent the first actual size difference between the i-th and j-th adjacent timber structure models at the connection point after virtual connection, where ΔL actual,ij The first actual length difference, ΔW actual,ij The first actual width difference, ΔH actual,ij This represents the first actual height difference; Δθ actual,ij d represents the first actual angle difference between the i-th and j-th adjacent timber structure models at the connection point after virtual connection; ideal,ij ΔL represents the first ideal splicing deviation between the i-th and j-th adjacent timber structure models at the connection point before the virtual connection; ideal,ij ΔW ideal,ij ΔH ideal,ij Both represent the first ideal size difference between the i-th and j-th adjacent timber structure models at the connection point before the virtual connection, where ΔL ideal,ij The first ideal length difference, ΔW ideal,ij The first ideal width difference, ΔH ideal,ij The first ideal height difference; Δθ ideal,ij This represents the difference in the first ideal angle between the i-th and j-th adjacent wooden structure models at the connection point before the virtual connection;

[0105] It is worth noting that the data contained in the first geometric information and the second geometric information are inconsistent. This is because the first geometric information refers to the geometric data of the connection points of adjacent wooden structure models within each group, extracted based on preset design parameters before virtual assembly. Specifically, it includes the first coordinate position, the first size, and the first angular direction. Its main function is to calculate the ideal splicing deviation, the ideal size difference, and the ideal angular difference. On the other hand, the second geometric information refers to the geometric data of the connection points of adjacent wooden structure models within each group, obtained after virtual assembly based on the actual simulated assembly results. Specifically, it includes the second coordinate position, the second size, and the second angular direction. Its main function is to calculate the actual splicing deviation, the actual size difference, and the actual angular difference, and compare them with the ideal values ​​to evaluate the splicing accuracy.

[0106] It is worth further explaining that the first geometric information refers to the design stage based on the preliminary design scheme, in which all components are generated according to precise design specifications and theoretically there is no error. Therefore, the coordinate position, size and angle direction in the first geometric information are all based on the design parameters under ideal conditions.

[0107] As for the second geometric information, in reality, due to unavoidable tolerances in the manufacturing process, such as cutting accuracy and material shrinkage, even when virtual assembly is performed in BIM software, these potential errors will be taken into account. Therefore, after virtual assembly, the actual size of some components will be slightly different from the design specifications, which will cause changes in the size and coordinate position in the second geometric information.

[0108] Therefore, the data contained in the first geometric information and the second geometric information are inconsistent in the above.

[0109] It is worth further elaborating that the above-described calculation process for component-level splicing accuracy, by defining the differences in geometric information before and after virtual splicing, establishes a quantitative model of the deviation between the ideal and actual states. This model can accurately reflect the degree of matching of components in terms of size, angle, coordinates, etc., providing a clear basis for subsequent component-level parameter optimization and significantly improving the design accuracy and manufacturing feasibility of individual components.

[0110] Second splicing accuracy value analysis unit: used to calculate the second splicing accuracy value between each adjacent assembly model;

[0111] Third geometric information extraction interface: used to extract the third geometric information of each adjacent assembly model at the connection point before virtual connection. The third geometric information includes the third coordinate position, the third size and the third angle direction.

[0112] The third calculation interface is used to calculate the second ideal splicing deviation, the second ideal size difference, and the second ideal angle difference at the connection point before the virtual connection for each adjacent assembly model based on the third geometric information.

[0113] The formulas for calculating the second ideal splicing deviation, second ideal size difference, and second ideal angle difference at the connection point before virtual connection for each adjacent assembly model are as follows:

[0114]

[0115] ΔL ideal,kl ′=|L k -L l |;

[0116] ΔW ideal,kl ′=|W k -W l |;

[0117] ΔH ideal,kl ′=|H k -H l |;

[0118] Δθ ideal,kl ′=|θ k -θ l |;

[0119] In the formula, d ideal,kl ′ represents the second ideal splicing deviation between the k-th assembly model and the l-th assembly model at the connection point before the virtual connection; ΔL ideal,kl ′、ΔW ideal,kl ′、ΔH ideal,kl ' represents the difference in the second ideal dimension between the k-th assembly model and the l-th assembly model at the connection point before the virtual connection, where ΔL ideal,kl ′ represents the second ideal length difference, ΔW ideal,kl ′ represents the second ideal width difference, ΔH ideal,kl ′ represents the second ideal height difference; Δθ ideal,kl ′ represents the difference in the second ideal angle between the k-th assembly model and the l-th assembly model at the connection point before the virtual connection; x k y k z k This represents the coordinate position of the k-th assembly model before the virtual connection, i.e., its three-dimensional coordinates; x l y l z l L represents the coordinate position of the l-th assembly model before the virtual connection, i.e., the three-dimensional coordinates; k W k H k and θk These represent the length, width, height, and angular direction of the k-th assembly model before the virtual connection; L l W l H l and θ l These represent the length, width, height, and angular direction of the l-th assembly model before the virtual connection.

[0120] The second virtual splicing interface is used to virtually splice each adjacent assembly model according to a preset assembly order.

[0121] Fourth geometric information extraction interface: used to obtain the fourth geometric information at the connection point of each adjacent assembly model after virtual splicing. The fourth geometric information includes the fourth coordinate position, the fourth size, and the fourth angular direction.

[0122] The fourth calculation interface is used to calculate the second actual splicing deviation, the second actual size difference, and the second actual angle difference at the connection points of each adjacent assembly model after virtual splicing, based on the fourth geometric information.

[0123] The second splicing accuracy value calculation interface is used to calculate the second splicing accuracy value between adjacent assembly models by combining the second ideal splicing deviation, second ideal size difference and second ideal angle difference at the connection point of each adjacent assembly model before virtual connection, and the second actual splicing deviation, second actual size difference and second actual angle difference at the connection point of each adjacent assembly model after virtual splicing.

[0124] The formula for calculating the second splicing accuracy value between each adjacent assembly model is as follows:

[0125]

[0126] In the formula, P2 kl d represents the second splicing accuracy value between the k-th assembly model and the l-th assembly model. actual,kl ′ represents the second actual splicing deviation between the k-th assembly model and the l-th assembly model at the connection point after virtual connection; ΔL actual,kl ′、ΔW actual,kl ′、ΔH actual,kl ' represents the second actual size difference between the k-th assembly model and the l-th assembly model at the connection point after virtual connection, where ΔL actual,kl ′ represents the second actual length difference, ΔW actual,kl ' is the second actual width difference, ΔH actual,kl ′ represents the second actual height difference; Δθ actual,kl′ represents the second actual angle difference between the k-th assembly model and the l-th assembly model at the connection point after virtual connection; d ideal,kl ′ represents the second ideal splicing deviation between the k-th assembly model and the l-th assembly model at the connection point before the virtual connection; ΔL ideal,kl ′、ΔW ideal,kl ′、ΔH ideal,kl ' represents the difference in the second ideal dimension between the k-th assembly model and the l-th assembly model at the connection point before the virtual connection, where ΔL ideal,kl ′ represents the second ideal length difference, ΔW ideal,kl ′ represents the second ideal width difference, ΔH ideal,kl ′ represents the second ideal height difference; Δθ ideal,kl ′ represents the difference in the second ideal angle between the k-th assembly model and the l-th assembly model at the connection point before the virtual connection;

[0127] It is worth noting that the reasons for the inconsistency between the data contained in the third and fourth geometric information are similar to those for the inconsistency between the data contained in the first and second geometric information, and will not be elaborated here.

[0128] It is worth further explaining that the above-mentioned method proposes a complete splicing accuracy analysis method at the assembly model level. By extracting the difference in geometric information at the macro level, key error points between assembly models can be identified. This method helps to discover structural problems in modular assembly, such as interface mismatch and positioning offset, thereby guiding the optimization of subsequent assembly strategies and improving the compatibility between modules and the overall structural stability.

[0129] Overall splicing accuracy value acquisition unit: used to combine the first splicing accuracy value and the second splicing accuracy value to obtain the overall splicing accuracy value of the pre-built wooden structure building model;

[0130] It is worth noting that when calculating the overall splicing accuracy value, the number of all first splicing accuracy values ​​and the number of all second splicing accuracy values ​​should be counted first. Then, the average of all first splicing accuracy values ​​and the average of all second splicing accuracy values ​​should be taken. Finally, the average of the sum of the average of all first splicing accuracy values ​​and the average of all second splicing accuracy values ​​should be taken to obtain the overall splicing accuracy value of the pre-constructed wooden structure building model.

[0131] It is worth further explaining that the above-mentioned dual-level splicing accuracy evaluation mechanism, that is, to conduct independent accuracy analysis on the component level and the assembly model level respectively, and then merge them to form an overall splicing accuracy value, helps to accurately identify the source of error, improve the pertinence and effectiveness of model optimization, and thus provide data support for subsequent automated correction.

[0132] Historical overall splicing accuracy value acquisition unit: used to acquire the historical overall splicing accuracy value of at least two completed pre-built wooden structure building models in historical data;

[0133] Mean calculation unit: used to calculate the mean of the overall historical splicing accuracy values;

[0134] Final Timber Structure Building Model Determination Unit: If the overall splicing accuracy value of the pre-built timber structure building model is greater than the average of the historical overall splicing accuracy values, then the current pre-built timber structure building model is retained and used as the final timber structure building model; if the overall splicing accuracy value of the pre-built timber structure building model is less than or equal to the average of the historical overall splicing accuracy values, then the current pre-built timber structure building model is adjusted until the final timber structure building model is obtained.

[0135] It is worth noting that the above-mentioned mechanism, which introduces a judgment mechanism based on historical data analysis to set threshold standards and determine whether the current model meets engineering requirements, serves as a third layer of stitching accuracy analysis mechanism. This mechanism enables intelligent decision-making for model optimization, ensuring that the final output model effectively surpasses the previous average level in overall stitching accuracy. This avoids blind modifications, improves model iteration efficiency, and enhances the system's adaptability and practicality.

[0136] The first and second splicing accuracy value extraction interfaces are used to extract the first splicing accuracy value and / or the second splicing accuracy value respectively based on the fact that the overall splicing accuracy value of the current pre-built wooden structure building model is less than or equal to the average of the historical overall splicing accuracy values.

[0137] First Difference Determination Interface: This interface is used to obtain each first difference value for adjacent wooden structure models within each group based on the extracted first splicing accuracy value, set a first allowable range for each first difference value, and determine whether each first difference value exceeds the first allowable range. The first difference value includes:

[0138] The difference between the first actual splicing deviation and the first ideal splicing deviation;

[0139] The difference between the first actual size difference and the first ideal size difference;

[0140] The difference between the first actual angle difference and the first ideal angle difference;

[0141] If any of the first differences exceeds the first allowable range, the first correction interface is executed; otherwise, the process jumps to the second difference determination interface.

[0142] It is worth noting that the first allowable range for splicing deviations mentioned above is usually set according to the project design specifications, such as ±2mm; the first allowable range for dimensional differences mentioned above is usually determined according to the manufacturing tolerances of the components, such as ±1mm; and the first allowable range for angular differences mentioned above is usually set according to the design requirements, such as ±0.5 degrees.

[0143] First correction interface: used to, when any first difference exceeds the first allowable range, call the second geometric information of the current timber structure model and perform a first correction on the second geometric information; the first correction includes:

[0144] Adjust the second dimension of the current timber structure model to reduce the difference between the first actual dimension difference and the first ideal dimension difference, i.e., reduce the deviation;

[0145] Adjust the second angle direction of the current timber structure model to reduce the difference between the first actual angle difference and the first ideal angle difference, that is, reduce the deviation;

[0146] Adjust the second coordinate position of the current timber structure model to reduce the difference between the first actual splicing deviation and the first ideal splicing deviation, i.e., reduce the deviation;

[0147] It is worth noting that the reason for choosing the second geometric information for the first correction is as shown in Table 1 below:

[0148] Table 1: Detailed Comparison of Selecting Second Geometric Information for First Correction

[0149]

[0150]

[0151] Therefore, based on Table 1, when any of the first differences is found to exceed the first allowable range, the second geometric information obtained after the simulated assembly must be used to accurately identify the problem and make targeted and effective modifications.

[0152] The second difference determination interface is used to obtain each second difference of adjacent assembly models based on the extracted second splicing accuracy value, set a second allowable range for each second difference, and determine whether each second difference exceeds the second allowable range; the second difference includes:

[0153] The difference between the second actual splicing deviation and the second ideal splicing deviation;

[0154] The difference between the second actual size difference and the second ideal size difference;

[0155] The difference between the second actual angle difference and the second ideal angle difference;

[0156] If any of the second differences exceeds the second allowable range, the second correction interface is executed; otherwise, the process returns to the overall splicing accuracy value acquisition unit and the overall splicing accuracy value of the pre-built wooden structure building model is recalculated.

[0157] It is worth noting that the first allowable range for splicing deviations mentioned above is usually set according to the project design specifications and is usually slightly larger than the first allowable range, such as ±3mm; the first allowable range for dimensional differences mentioned above is usually determined according to the manufacturing tolerances of the assembly model and is usually slightly larger than the first allowable range, such as ±1.5mm; the first allowable range for angle differences mentioned above is usually set according to the design requirements and is usually slightly larger than the first allowable range, such as ±1 degree.

[0158] It is worth further explaining the reasons for the discrepancy between the first and second allowable ranges, as follows:

[0159] The first allowable range applies to individual timber structure models. From the perspective of design specifications, an individual timber structure model is the basic unit of the entire building, and its accuracy directly affects the quality of the subsequent assembled model. Therefore, during the design phase, the splicing accuracy requirements for individual timber structure models are usually high, and the allowable error range is small. The second allowable range applies to assembled models. Also from the perspective of design specifications, assembled models are larger modules composed of multiple timber structure models. Although the accuracy of each individual timber structure model is high, additional errors may be introduced when assembling them into an assembled model due to factors such as the interaction between multiple components and the installation sequence. Therefore, during the design phase, the splicing accuracy requirements for assembled models are relatively more lenient, and the allowable error range is slightly larger.

[0160] The second correction interface is used to call the fourth geometric information of the current assembly model and perform a second correction on the fourth geometric information if any second difference exceeds the second allowable range; the second correction includes:

[0161] Adjust the size of the fourth dimension of the current assembly model to reduce the difference between the second actual dimension difference and the second ideal dimension difference, i.e., reduce the deviation;

[0162] Correct the fourth angle direction of the current assembly model to reduce the difference between the second actual angle difference and the second ideal angle difference, that is, reduce the deviation;

[0163] Modify the fourth coordinate position of the current assembly model to reduce the difference between the second actual splicing deviation and the second ideal splicing deviation, i.e., reduce the deviation;

[0164] It is worth noting that the reason for choosing the fourth geometric information for the second correction is similar to the reason for choosing the second geometric information for the first correction, and will not be elaborated on here.

[0165] The final timber structure building model acquisition interface is used to obtain the adjusted pre-built timber structure building model after completing all the first and second corrections, and then return to the first splicing accuracy value analysis unit to re-analyze the splicing accuracy of the adjusted pre-built timber structure building model until the overall splicing accuracy value of the adjusted pre-built timber structure building model is greater than the average of the historical overall splicing accuracy values, thus obtaining the final timber structure building model.

[0166] It is worth noting that, as described above, this invention, by introducing a multi-level splicing accuracy analysis mechanism, achieves accurate modeling and error control of pre-constructed wooden building models at different granularity levels, significantly improving the overall construction quality and efficiency.

[0167] In this invention, "multi-level" refers to the process of dividing the timber structure building model into levels during BIM modeling and virtual assembly, and performing splicing accuracy analysis and optimization adjustments at different levels. Specifically, this includes the following three levels:

[0168] I. Component level refers to individual wooden structural components and their geometric parameters. At this level, by comparing the first geometric information (ideal state) and the second geometric information (virtual splicing state) of each component, the first splicing accuracy value is calculated, thereby achieving precise control over the detailed design of component size, angle, interface position, etc. This can avoid the overall structural deviation caused by the accumulation of errors in individual components and improve the consistency between component manufacturing and subsequent on-site installation.

[0169] Second, the assembly model level refers to a local assembly module composed of multiple components. At this level, based on the third and fourth geometric information between adjacent assembly models, the second splicing accuracy value is calculated, thereby achieving macro-optimization of the connection method, tolerance matching, and positioning coordination between assembly modules. This can enhance the adaptability and compatibility between modules and reduce the difficulty of overall structural docking.

[0170] Third, the overall model level refers to the complete pre-constructed timber structure building model formed by combining all the assembled models. At this level, the overall splicing accuracy value is calculated by combining the first splicing accuracy value and the second splicing accuracy value. By comparing it with the average splicing accuracy value in historical data, it is determined whether the model needs to be corrected. This enables dynamic evaluation of global splicing performance and supports data-driven design optimization, thereby ensuring that the final model output each time is better than the previous average level in terms of overall splicing accuracy, so that the final output model can effectively meet the actual needs of the project.

[0171] Timber Structure Building Acquisition Module: Connected to the Precision Analysis Module, it is used to export the final timber structure building model to generate construction drawings, and obtain the timber structure building based on the construction drawings and in combination with production equipment;

[0172] First, use BIM software (such as Revit, Tekla Structures, etc.) to export the final timber structure building model as a standard format file (e.g., IFC, DWG, or DXF). Then, check and organize the exported file to ensure that each component has a clear number, dimension, material specification, and processing requirements. Next, create a detailed component list, listing the name, number, material, dimension, and quantity of all components.

After all the components have been produced according to the drawing requirements, the on-site installation stage begins. During the installation process, simply follow the preset assembly sequence until a complete wooden component building is obtained.
