Description

Technical Field

[0001] The present application relates to the technical field of architectural design, and in particular to a method, device, electronic device and computer-readable storage medium for designing prefabricated buildings based on a BIM platform. Background Art

[0002] At present, Building Information Modeling (BIM) is a new tool in architecture, engineering and civil engineering. Among them, the BIM platform is a computer-aided design platform based on three-dimensional graphics, object-oriented, and related to architecture.

[0003] In the existing technology, with the continuous development of the construction industry, prefabricated buildings have also been greatly improved. However, the current design process of prefabricated buildings is mainly completed by the "re-molding" method, which often leads to a lack of information transmission between the structural model and the prefabricated model. Designers can only perform comparative analysis and adjust the model, which results in problems such as large workload and low efficiency. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a method, device, electronic device and computer-readable storage medium for prefabricated building design based on the BIM platform, which can achieve the technical effect of improving the work efficiency of building design.

[0005] In a first aspect, an embodiment of the present application provides a method for designing an assembled building based on a BIM platform, comprising:

Through the linkage between the prefabricated BIM model and the BIM overall model, when the verification results show that the positions and sizes of the components of the prefabricated BIM model and the components of the BIM overall model are inconsistent or do not meet the review requirements, automatic adjustment can be achieved to ensure the consistency of the construction drawing data, thereby reducing the workload of designers and improving the design efficiency of designers; therefore, the prefabricated building design method based on the BIM platform can achieve the technical effect of improving the work efficiency of building design.

[0013] Furthermore, the step of verifying the BIM overall model and the assembled BIM model to obtain verification results includes:

[0020] In the above implementation process, it can be determined whether there is a deviation in the comparison of components between the prefabricated BIM model and the BIM overall model based on the verification results; if there is no deviation, the next step is executed; if there is a deviation, the prefabricated BIM model or the BIM overall model is reviewed and corrected according to the preset conditions until the prefabricated BIM model or the BIM overall model is consistent before proceeding to the next step.

[0025] Furthermore, the step of loading the building BIM model and the structural BIM model into the resource platform to generate a BIM overall model includes:

[0026] Screening the building BIM model and the structural BIM model and obtaining components of the building professional model and the structural professional model;

[0027] The BIM overall model is obtained by assembling components of the architectural professional model and the structural professional model.

[0028] In the above implementation process, the components of the required architectural professional model and structural professional model are screened and filtered out, and then the filtered components are assembled to finally create a BIM overall model.

[0029] Furthermore, the step of generating an assembled BIM model according to the BIM overall model includes:

[0030] Get the preset assembly plan;

[0031] According to the preset assembly scheme, some components of the BIM overall model are replaced by prefabricated components to generate the assembled BIM model.

[0032] In the above implementation process, the prefabricated BIM model is a model that includes all the components of the building, and according to the assembly plan, some components are replaced with prefabricated components to form the final BIM model.

At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0070] The embodiment of the present application provides a prefabricated building design method and device based on the BIM platform, which can be applied to the forward design of prefabricated buildings; the prefabricated building design method based on the BIM platform establishes a unified resource platform through a preset BIM design standard, generates a BIM overall model based on the building BIM model and the structural BIM model on the resource platform, and then generates an prefabricated BIM model based on the BIM overall model; through the linkage between the prefabricated BIM model and the BIM overall model, when the verification results show that the positions and sizes of the components of the prefabricated BIM model and the components of the BIM overall model are inconsistent or do not meet the drawing review requirements, automatic adjustment can be achieved to ensure the consistency of the construction drawing data, thereby reducing the workload of designers and improving the design efficiency of designers; therefore, the prefabricated building design method based on the BIM platform can achieve the technical effect of improving the work efficiency of building design.

[0071] See also Figure 1 , Figure 1 A schematic diagram of a process flow of a prefabricated building design method based on a BIM platform provided in an embodiment of the present application, the prefabricated building design method based on a BIM platform includes:

[0072] S100: Obtain BIM design standards, architectural BIM models and structural BIM models.

[0073] Exemplarily, BIM design standards include one or more of model naming standards, model building standards, model drawing standards, design collaboration standards, model delivery standards, and component customization standards; it should be noted that the design standards are the benchmark for prefabricated building design, and unified design standards are conducive to information exchange between designers, thereby improving work efficiency.

[0074] Exemplarily, the model naming standard includes one or more of the following naming: project folder, model, component, project template, work set, elevation grid, working view, view template, filter, material, fill style, drawing, shared parameters, etc.; a unified model naming standard can ensure the uniqueness of model naming, which is conducive to the recognition and calling of the model by software or program.

[0075] For example, in the model building standard, regulations are set for model accuracy, color, spatial position, and unit settings according to different professions and different design stages, and the model splitting principles are unified, standard work sets and work views are created, and model creation operations are standardized.

[0076] Illustratively, a model drawing standard is a specification for a standardized process for model drawing.

[0077] For example, the design collaboration standard is the specification of the responsibility scale, communication mode, model collaboration process, and design collaboration of project participants during the model creation process.

[0078] Exemplarily, the model delivery standard is the specification of the model delivery standard and the deliverable category; the delivery standard includes model accuracy, information depth, geometric expression accuracy, etc., and the deliverable category includes information model, attribute table, engineering drawing, calculation book, etc.

[0079] Exemplarily, the component customization standard includes one or more of a template used to create a component, a component creation standard, a naming rule, a parameter setting, etc.

[0080] S200: Build a resource platform according to BIM design standards, which includes a basic resource library.

[0081] For example, based on the BIM design standards obtained by S100, a unified resource platform is established. Designers in different professions and different design stages can complete data calls on the same basic resource platform, and new basic data are generated during the model building process, which can be stored in the basic database in accordance with the design standard requirements; the content of the basic resource library includes standard component libraries, project templates, design instructions, standard practices, common nodes, etc.

[0082] Exemplarily, standard components are created through component customization standards, and a standard component library is formed for different standard components.

[0083] For example, a project template provides presets for view templates, settings (such as units, fill styles, line styles, line widths, view scales, etc.) and filters for new projects.

[0084] For example, the design description specifies the specific implementation project overview, project-related design specifications, a textual description of standard practices, project design considerations, and interpretation of design clauses.

[0085] Illustratively, the standard practice specifies a textual description of standard construction practices for projects of the same type.

[0086] For example, generic nodes can be used as node detail drawings that can be reused in projects of the same type.

[0087] For example, a component is a replaceable part that actually exists in a system. It implements a specific function, conforms to a set of interface standards and can implement a set of interfaces. A component represents a part of the physical implementation of a system, including software code (source code, binary code or executable code) or its equivalent (such as a script or command file). In a diagram, a component is represented as a rectangle with a label. In actual engineering operations, various machines and structures are widely used. The parts and components that make up machines and structures are collectively referred to as components in engineering mechanics.

[0088] S300: Load the architectural BIM model and the structural BIM model into the resource platform to generate a BIM overall model.

[0089] Exemplarily, the architectural BIM model is a building model with architectural-related parameter information. In the prefabricated building model, the main components extracted are the enclosing walls, internal partition walls, bay windows, stairs, air-conditioning panels, etc. that are not included in the structural BIM model; the structural BIM model is a model composed of horizontal load-bearing components and vertical load-bearing components. When the prefabricated building BIM model is molded, it complements the architectural BIM model.

[0090] Exemplarily, the BIM overall model is a combination of the architectural BIM model and the structural BIM model. The model integrates all components of the building and the structure to meet all component requirements required for prefabricated design.

[0091] S400: Generate an assembled BIM model according to the BIM overall model.

[0092] Exemplarily, the BIM overall model is created as an assembled BIM model, wherein the assembled building BIM model is a model that includes all components of the building, and according to the assembly plan, some components are replaced with prefabricated components to finally form the BIM model.

[0093] S500: Verify the BIM overall model and the assembled BIM model to obtain verification results.

[0094] Exemplarily, the verification result can show whether there are differences between the BIM overall model and the prefabricated BIM model. If the components of the two models differ in component size and position, the BIM overall model created by S300 or the prefabricated BIM model created by S400 can be modified according to the verification result to maintain consistency between the BIM overall model and the prefabricated BIM model.

[0095] S600: Obtain construction drawing data based on the BIM overall model, the assembled BIM model and the verification results.

[0096] Exemplarily, based on the verification results, it can be determined whether the prefabricated BIM model and the BIM overall model are consistent; when the prefabricated BIM model and the BIM overall model are consistent, the construction drawing data generated based on the BIM overall model and the prefabricated BIM model can ensure the data consistency of each construction drawing in the construction drawing data.

[0097] In some embodiments, the prefabricated building design method based on the BIM platform establishes a unified resource platform through a preset BIM design standard, generates a BIM overall model based on the building BIM model and the structural BIM model on the resource platform, and then generates an prefabricated BIM model based on the BIM overall model. Through the linkage between the prefabricated BIM model and the BIM overall model, when the verification results show that the positions and sizes of the components of the prefabricated BIM model and the components of the BIM overall model are inconsistent or do not meet the review requirements, automatic adjustment can be achieved to ensure the consistency of the construction drawing data, thereby reducing the workload of designers and improving the design efficiency of designers; therefore, the prefabricated building design method based on the BIM platform can achieve the technical effect of improving the work efficiency of building design.

[0098] See also Figure 2 , Figure 2 A flowchart of another method for designing prefabricated buildings based on a BIM platform is provided in an embodiment of the present application.

[0099] Exemplarily, S500: verifying the BIM overall model and the assembled BIM model to obtain the verification result includes:

[0100] S510: Performing an overlay comparison analysis on the components of the prefabricated BIM model and the BIM overall model to obtain a verification result, where the verification result includes comparison prompt information of component size information and component spatial position information between the prefabricated BIM model and the BIM overall model.

[0101] Exemplarily, the prefabricated BIM model and the BIM overall model are superimposed and compared for analysis, and further correlation analysis can be performed; the verification result can determine whether there are differences between the above-mentioned prefabricated BIM model and the BIM overall model. If the components of the two models differ in component size and position, the prefabricated BIM model or the BIM overall model can be modified according to the verification result; if there is no difference in component size and position between the prefabricated BIM model and the BIM overall model, or if there is a difference but it is caused by prefabricated technical construction measures, the two models can be directly correlated and analyzed through the underlying data of the model.

[0102] In some embodiments, when performing an overlay comparative analysis on the components of the prefabricated BIM model and the BIM overall model, the sizes (length, width, height, etc.) and spatial positions of the components of the prefabricated BIM model and the BIM overall model can be comparatively analyzed based on the characteristics of the prefabricated building.

[0103] Exemplarily, S510: after the step of performing superposition comparison analysis on the components of the assembled BIM model and the BIM overall model to obtain the verification result, the method further includes:

[0104] S511: judging whether there is a deviation between the components of the prefabricated BIM model and the BIM overall model according to the verification result; if there is no deviation between the components of the prefabricated BIM model and the BIM overall model, executing S600;

[0105] S512: If there is a deviation between the components of the prefabricated BIM model and the BIM overall model, the prefabricated BIM model or the BIM overall model is reviewed and corrected according to preset conditions, the prefabricated BIM model or the BIM overall model is updated, and S510 is executed.

[0106] For example, based on the verification results, it can be determined whether there is a deviation in the comparison of components between the prefabricated BIM model and the BIM overall model; if there is no deviation, the next step is executed; if there is a deviation, the prefabricated BIM model or the BIM overall model is reviewed and corrected according to preset conditions until the prefabricated BIM model or the BIM overall model is consistent before proceeding to the next step.

[0107] In some implementations, the components of the prefabricated BIM model and the BIM overall model are superimposed and compared and analyzed; according to the characteristics of the prefabricated building, the size (length, width, height, etc.) and spatial position of the components are compared and analyzed, and the designer can perform the following operations according to the comparison prompt information:

[0108] If the prompt information shows that there is no deviation between the components of the prefabricated BIM model and the BIM overall model, the designer chooses to proceed to the next design work (the next step of this application is to generate construction drawing data).

[0109] If the prompt information shows that there is a deviation between the components of the prefabricated BIM model and the BIM overall model, a warning sign will appear on the component with the deviation, and the deviated model will be automatically reviewed and corrected. The designer needs to confirm whether the deviation of the component has been corrected. The specific method is as follows:

[0110] 1) If there is a component deviation prompt message, the designer will judge that it is a structural measure added to meet the needs of prefabricated installation or the construction of prefabricated components, etc., and there is no need to adjust the components, and proceed to the next step of design work (generating construction drawing data);

[0111] 2) If there is a component deviation prompt message, and the designer determines that it is a component problem of the prefabricated BIM model, the prefabricated BIM model will be modified. After completion, the prefabricated BIM model will be updated, and the superposition comparison analysis will be automatically performed until it is determined that there is no problem and the next step of design work is entered;

[0112] 3) If there is a component deviation prompt, the designer will determine that it is a component problem of the BIM overall model, and then modify the BIM overall model, and automatically adjust the different components according to the assembly plan. Then perform the superposition comparison analysis again to confirm that there is no deviation, and proceed to the next step of design work.

[0113] In some embodiments, the BIM overall model and the prefabricated BIM model can be automatically associated, that is, when the BIM overall model or the prefabricated BIM model is modified, the two models can be synchronously linked by modifying either model.

[0114] Exemplarily, the construction drawing data includes architectural construction drawings, structural construction drawings and prefabricated construction drawings. S600: the step of obtaining the construction drawing data according to the BIM overall model, the prefabricated BIM model and the verification result includes:

[0115] S610: After judging that there is no deviation between the components of the assembled BIM model and the BIM overall model according to the verification result, obtain the building construction drawing and the structural construction drawing according to the BIM overall model;

[0116] S620: Obtaining the prefabricated construction drawing according to the prefabricated BIM model.

[0117] Exemplarily, after determining that the prefabricated BIM model and the BIM overall model are consistent, the architectural construction drawings and structural construction drawings are produced according to the BIM overall model, and the prefabricated construction drawings are obtained according to the prefabricated BIM model, which can ensure the consistency of the architectural construction drawings, structural construction drawings, and prefabricated construction drawings.

[0118] Exemplarily, S300: loading the building BIM model and the structural BIM model into the resource platform to generate a BIM overall model includes:

[0119] S310: Screening the architectural BIM model and the structural BIM model and obtaining components of the architectural professional model and the structural professional model;

[0120] S320: Assemble components of the architectural professional model and the structural professional model to obtain a BIM overall model.

[0121] Exemplarily, the components of the required architectural professional model and structural professional model are screened and filtered out, and then the filtered components are assembled to finally create a BIM overall model; wherein, for example: the structural professional model includes shear wall components, structural beam components, etc., and the components of the architectural professional model include exterior wall components, interior wall panel components, etc.

[0122] In some embodiments, traditional prefabricated building design mainly adopts the BIM "re-molding" method, which is a two-dimensional drawing to a three-dimensional model; and the creation of a BIM overall model is mainly to achieve two goals: the BIM overall model serves as a bridge for prefabricated collaborative design, and the information of the BIM model of the building and structure can be transferred to the prefabricated BIM model; the design of prefabricated components is carried out directly in the BIM overall model, and the components required for the prefabricated BIM model are already included in the BIM overall model.

[0123] Exemplarily, S400: the step of generating an assembled BIM model according to the BIM overall model includes:

[0124] S410: Obtaining a preset assembly solution;

[0125] S420: According to a preset assembly plan, some components of the BIM overall model are replaced by prefabricated components to generate an assembled BIM model.

[0126] Exemplarily, the assembled BIM model is a model that includes all components of a building, and some components are replaced with prefabricated components according to the assembly plan to finally form the BIM model.

[0127] Exemplarily, after S400: generating an assembled BIM model according to the BIM overall model, the method further includes:

[0128] S430: Review the prefabricated specification clauses of the BIM overall model or prefabricated BIM model.

[0129] In some implementations, an automatic review function is performed on the mandatory provisions related to the assembly specification to achieve intelligent verification.

[0130] In some embodiments, the present application also provides an auxiliary tool kit. Figure 1 to Figure 2In the method embodiment shown, each functional module in the auxiliary tool kit can be called as needed; the auxiliary tool kit may include one or more of the following functional modules:

[0131] 1) Combine the loaded architectural BIM model and structural BIM model to create a BIM overall model;

[0132] 2) Generate an assembled BIM model based on the overall BIM model;

[0133] 3) Perform a comparison analysis on the components of the BIM overall model and the prefabricated BIM model to generate a verification result; based on the verification result, the designer outputs instructions to choose whether to adjust the BIM overall model or the prefabricated BIM model;

[0134] 4) Output architectural construction drawings, structural construction drawings and prefabricated construction drawings;

[0135] 5) Intelligent verification to check the mandatory provisions of relevant prefabricated specifications.
