Description

Technical Field

[0001] The present invention relates to the technical field of road construction, and in particular to a BIM-based fragmentation design and assembly construction method. Background Art

[0002] Fragmentation, also known as ice crack, is a popular decorative technique, widely used in many fields such as floor paving, facade decoration and art decoration. Its unique artistic charm lies in the ability to use irregular blocks, such as stone, metal, wood, glass, cloth and other materials, through clever combination and collage, to create a natural, smooth and unique texture effect.

[0003] However, although the splicing technique has extremely high aesthetic value, it faces some key technical difficulties and challenges in actual construction and technical implementation.

[0004] Design flexibility and unpredictability of finished product effects: Current fragmented construction mostly relies on on-site design and immediate processing, lacking standardized design drawings and prefabrication plans. It is difficult for designers to accurately foresee the final decorative effect before construction, resulting in uncertainty in project quality control and effect presentation. This uncertainty increases the risk of the project and also limits the designer's room for creativity.

[0005] Complexity of pre-design and difficulty of adjustment: Although a few projects have tried to pre-design fragments, the design process is cumbersome and time-consuming due to the complexity of random effects and the limitations of drawing technology. Once the design needs to be changed, such as adjusting the color, texture or block size, it is often necessary to redraw the entire pattern, which increases time and cost.

[0006] Environmental impact during construction: During on-site construction, the shaping and cutting of blocks will generate a lot of noise, dust and sewage, which will have adverse effects on construction workers and the surrounding environment. These environmental problems not only increase the difficulty of construction and safety risks, but may also cause complaints and disputes.

[0007] Inefficient implementation: Workers need to constantly consider the combination of fragments during the construction process and make immediate adjustments based on actual conditions. This design-while-construction approach not only reduces construction efficiency, but may also lead to inconsistencies and defects in the decorative effects. In addition, due to the lack of standardized construction processes and specifications, the construction effects of different workers may also vary.

[0008] High material loss: The randomness of the fragmentation technique and the characteristics of on-site processing make it difficult for workers to accurately control the cutting and processing of blocks. This not only leads to a high material loss rate, increases project costs, but also wastes precious natural resources. At the same time, due to the high material loss, it also increases the difficulty and cost of waste disposal during the construction process.

[0009] To sum up, the existing splicing decoration technique has many technical defects and problems in the design and construction levels. These problems not only limit the application and development of splicing techniques in a wider range of fields, but also increase project risks and costs. Summary of the invention

[0010] In order to overcome the deficiencies of the prior art, the present invention provides a method for overcoming the above-mentioned defects, improving design efficiency and construction quality, and reducing material loss and environmental impact.

[0011] The technical means adopted by the present invention to solve the technical problem is: a fragmentation design and assembly construction method based on BIM, the improvement of which is that it includes:

[0012] S1: Draw or import the boundary outline of the area that needs to be fragmented in the BIM program, adjust the basic parameters of the BIM program according to the boundary outline of the area, and generate multiple random fragmented design schemes and multi-scheme reports;

[0013] S2: Compare and select according to the generated multi-scheme report, number the selected schemes, and obtain a basic design scheme;

[0014] S3: fine-tuning detailed parameters based on the basic design scheme so that the fragmentation effect meets the design requirements, and obtaining the final design scheme;

[0015] S4: Numbering the blocks of the final design solution in order of position, imposing the blocks, and outputting an imposition processing drawing and a layout report;

[0016] S5: Performing CNC cutting on the block material using the plate-making drawing, and marking and numbering the processed finished products one by one according to the numbers generated in S4;

[0017] S6: After the finished broken pieces are transported to the construction site, they are assembled in the order of numbers according to the assembly drawing.

[0018] The basic parameters in step S1 in the above technical solution include:

[0019] ① The number of schemes can control the number of random schemes generated at one time, which is used to provide multiple schemes for comparison; if none of them can meet the needs, it supports refreshing the scheme, and the unique number corresponding to each random square is used for subsequent reproduction of the scheme;

[0020] ② The number of basic blocks is used to control the number of pieces within the boundary contour. The more the number, the smaller the size of the pieces.

[0021] ③Multi-scheme generation switch, used to control whether to enable multi-scheme generation;

[0022] ④ Refresh the solution and generate a new set of random solutions;

[0023] ⑤ Material selection of broken blocks, used to specify the material type of broken blocks;

[0024] ⑥ Color matching scheme, used to preset or randomly generate color combinations of broken pieces.

[0025] The content of the multi-scheme report described in step S2 of the above technical scheme includes: the total number of schemes, the area of ​​the design area, the scheme number corresponding to each scheme, the total number of broken pieces, the total area of ​​the broken pieces, the gap area, the statistics of the size distribution of the broken pieces of each scheme, the analysis of the proportion of the gap area and the overall visual effect evaluation.

[0026] The detailed parameters in step S3 in the above technical solution include:

[0027] ① The spacing between the pieces is used to control the distance between the pieces; the edge gap width is used to control the distance between the pieces and the edge contour;

[0028] ②Polygonization: If the boundary contour is an arc, fit it into a polygon for the convenience of processing;

[0029] ③ Random rotation: randomly rotate the blocks at a certain angle to change the spacing and angle of the broken blocks;

[0030] ④The block shape is irregular and randomly generated, and the outline of the paving area can be customized;

[0031] ⑤ Texture mapping: mapping preset or user-defined texture patterns onto the surface of broken blocks.

[0032] The BIM program in step S1 of the above technical solution is a design method based on the built-in parametric program Grasshopper of the three-dimensional modeling software Rhino to generate models driven by variables, and realizes the adjustment of parameter modification to the linkage changes of the entire model, condition judgment, and data structure coding.

[0033] In the above technical solution, the colors of the blocks in step S4 are randomly screened and grouped, and the groups are numbered to obtain mixed solutions of different colors.

[0034] When the block is CNC cut using the plate-making drawing as described in step S5 of the above technical solution, the vertical edges of the block unit are cut and chamfered to realize the pebble fragmentation solution; the horizontal edges and vertical edges of the top surface of the block unit are cut and chamfered, or filled with skin to wrap, to realize the soft package style solution.

[0035] The above technical solution is based on the BIM-based fragmentation design and assembly construction method according to claim 1, characterized in that when the assembly construction is performed in the order of numbers by comparing the imposition tooling drawing in step S6, the blocks are randomly rotated within a certain angle range to optimize the assembly accuracy and enrich the visual effect.

[0036] The method described in the above technical solution also includes step S7, which specifically includes:

[0037] S7: Carry out quality inspection and acceptance on the splicing effect after construction is completed to ensure that it meets the design requirements; provide use and maintenance guidelines to guide users in daily maintenance and care to extend the service life and aesthetics of the splicing decoration.

[0038] The beneficial effects of the present invention are:

[0039] Significantly improve the efficiency and flexibility of scheme design: Through intelligent means, the present invention does not need to rely on manual drawing drawings, and can automatically generate a variety of design schemes, easily meet the needs of multiple scheme comparison, greatly shorten the design cycle, improve work efficiency, and ensure the diversity and innovation of design schemes;

[0040] Visualization and precise control based on BIM technology: Using advanced BIM technology, random visualization of design effects is realized, making the design results not only controllable but also adjustable. At the same time, it effectively avoids the common problems of on-site improvisation and lack of planning in traditional piecemeal construction, ensuring the accuracy and consistency of the construction process;

[0041] Promote green construction and reduce environmental impact: By combining factory processing with on-site assembly, environmental problems such as sewage, noise, dust and waste generated by on-site construction can be effectively avoided, significantly improving the environmental friendliness of the construction process; at the same time, this model also reduces on-site management and cleaning costs, achieving a dual improvement in economic and environmental benefits.

[0050] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0051] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0052] like Figure 1 As shown in the figure, they are the application scenarios and styles of fragmented puzzles in different scenarios. Figure 1 (a) For paving squares or roads, Figure 1 (b) Planting grass and paving roads, Figure 1 (c) is the facade grille, Figure 1 (d) is a Chinese window grille. Figure 1 (e) is a suspended ceiling, Figure 1 (f) is the facade decoration.

[0053] This shows the wide application of the decorative technique of patchwork. However, because of this, the patchwork design process in different scenarios is cumbersome and time-consuming due to the complexity of random effects and the limitations of drawing technology. At the same time, due to the unpredictability of on-site construction results, standardized design drawings are often very different from the actual effects.

[0054] Based on this, Figure 2 As shown, the present application provides a BIM-based fragmentation design and assembly construction method, which specifically includes the following steps:

[0055] S1: Draw or import the boundary outline of the area that needs to be fragmented into the BIM program, adjust the basic parameters of the BIM program according to the boundary outline of the area, and generate multiple random fragmented design schemes and a multi-scheme report.

[0056] like Figure 3 As shown, Figure 3 (a) is a boundary outline of the fragmented design area under an exemplary embodiment. After it is imported into the BIM program, Figure 3 As shown in (b), three pieces of patchwork design schemes are randomly generated. In practical applications, the boundary contour map is not restricted by shape or size, and the number of generated schemes can be increased or decreased at will.

[0057] In one possible implementation, the BIM program is a design method based on Grasshopper, a built-in parametric program of the 3D modeling software Rhino, which uses variables to drive model generation, and realizes parameter modification to adjust the linkage changes of the entire model, conditional judgment, and data structure coding.

[0058] S2: Compare and select according to the generated multi-scheme report, number the selected schemes, and obtain a basic design scheme.

[0059] S3: Based on the basic design scheme, fine-tune the detailed parameters so that the fragmentation effect meets the design requirements and obtain the final design scheme.

[0060] S4: Numbering the blocks of the final design solution in order of position, imposing the blocks, and outputting an imposition processing drawing and a layout report.

[0061] As shown in the figure, the main contents of the layout report include: cutting area, scrap area, scrap rate, etc., which can be used for processing cost accounting, material saving accounting, etc.

[0062] S5: Perform CNC cutting on the block material using the plate-making drawing, and mark and number the finished products one by one according to the numbers generated in S4.

[0063] S6: After the finished broken pieces are transported to the construction site, they are assembled in the order of numbers according to the assembly drawing.

[0064] In a possible implementation, the method further includes step S7, which specifically includes:

[0065] Carry out quality inspection and acceptance on the splicing effect after construction is completed to ensure that it meets the design requirements; provide use and maintenance guidelines to guide users in daily maintenance and care to extend the service life and aesthetics of the splicing decoration.

[0066] In a possible implementation, the basic parameters in step S1 include:

[0067] ① The number of schemes can control the number of random schemes generated at one time, which is used to provide multiple schemes for comparison; if none of them can meet the needs, it supports refreshing the scheme, and the unique number corresponding to each random square is used for subsequent reproduction of the scheme;

[0068] ② The number of basic blocks is used to control the number of pieces within the boundary contour. The more the number, the smaller the size of the pieces.

[0069] ③Multi-scheme generation switch, used to control whether to enable multi-scheme generation;

[0070] ④ Refresh the solution and generate a new set of random solutions;

[0071] ⑤ Material selection of broken blocks, used to specify the material type of broken blocks;

[0072] ⑥ Color matching scheme, used to preset or randomly generate color combinations of broken pieces.

[0073] In one possible implementation, the content of the multi-scheme report in step S2 includes: the total number of schemes, the area of ​​the design area, the scheme number corresponding to each scheme, the total number of broken pieces, the total area of ​​the broken pieces, the gap area, the statistics of the size distribution of the broken pieces of each scheme, the gap area ratio analysis and the overall visual effect evaluation.

[0074] In an exemplary embodiment, as shown in the following table (1), they are Figure 3 The multi-scheme report corresponding to the piecemeal design scheme generated by the boundary outline map of the piecemeal design area shown.

[0075]

[0076] Table 1

[0077] Optionally, the content of the multi-scheme report can be increased or decreased as desired according to actual on-site needs to provide more schemes for comparison.

[0078] In a possible implementation, the detailed parameters in step S3 include:

[0079] ① The spacing between the pieces is used to control the distance between the pieces; the edge gap width is used to control the distance between the pieces and the edge contour;

[0080] ②Polygonization: If the boundary contour is an arc, fit it into a polygon for the convenience of processing;

[0081] ③ Random rotation: randomly rotate the blocks at a certain angle to change the spacing and angle of the broken blocks;

[0082] ④The block shape is irregular and randomly generated, and the outline of the paving area can be customized;

[0083] ⑤ Texture mapping: mapping preset or user-defined texture patterns onto the surface of broken blocks.

[0084] In one possible implementation, Figure 4 As shown, the fragment spacing indicated by the final design scheme in step S3 is adjusted to an appropriate value, and only the gap model is extracted to obtain a grille-type design scheme, which can ensure that the grille-type design scheme meets specific design requirements, such as aesthetics and structural strength.

[0085] In one possible implementation, Figure 5 As shown, the colors of the blocks in step S4 are randomly screened and grouped, and the groups are numbered to obtain mixed schemes of different colors. Through carefully designed color matching and grouping, a harmonious, unified or contrasting visual effect can be created to meet different aesthetic needs.

[0086] In one possible implementation, Figure 6-7 As shown, in step S5, when the block is CNC cut using the plate-making drawing, the vertical edges of the block unit are cut and chamfered to realize the pebble fragmentation scheme; the horizontal edges and vertical edges of the top surface of the block unit are cut and chamfered, or filled with skin to wrap, to realize the soft package style scheme.

[0087] In one possible implementation, Figure 8 As shown, when the assembly construction is performed in the order of numbers according to the comparison of the panel assembly drawing in step S6, the blocks are randomly rotated within a certain angle range to optimize the assembly accuracy and enrich the visual effect.

[0091] Visualization and controllability of random effects based on BIM technology:

[0092] The present invention utilizes BIM (Building Information Modeling) technology to realize the visualization of random effects of patchwork decoration, so that the design results can be previewed and adjusted before construction; through the visualization function of BIM technology, designers can intuitively see the effects of different plans, so as to make more accurate decisions and adjustments; the controllability and adjustability of the results avoid the problem of casual design while construction on site in traditional patchwork construction, and ensure the consistency and stability of the decorative effect.

[0093] Realize green construction and reduce site management costs:

[0094] The present invention adopts the method of factory processing and on-site assembly, which effectively avoids environmental problems such as sewage, noise, dust and waste generated by on-site construction; the factory production method not only improves processing accuracy and efficiency, but also reduces on-site management and cleaning costs, achieving the goal of green construction; by optimizing the construction process and resource allocation, the present invention further improves the overall benefit and sustainability of the project.
