Description

Technical Field

[0001] This invention relates to the field of building structure design technology, and in particular to a hybrid building structure design method based on EasyBIM. Background Technology

[0002] EasyBIM is a domestically developed industrial design software based on Building Information Modeling (BIM) technology, specifically designed for the architectural field. It integrates 2D and 3D structural design, boasting high platform smoothness and fast processing speed, significantly improving design efficiency and quality. Currently, structural construction drawing design often employs a single design software or platform. CAD software possesses advantages in 2D design, enabling more efficient 2D graphical representation of structural design results and is suitable for drawing construction drawings using legends, conforming to industry practices. However, because it is not a digital design software, all drawn elements are simple point and line 2D elements, unable to store building model information to provide value for subsequent quantity calculations, construction, and operation and maintenance, thus limiting its functionality. Revit software possesses advantages in 3D design, with 3D visualization capabilities, enabling collaboration among various disciplines under BIM technology. However, some drafting representations do not conform to industry practices, making drafting difficult. Although it is a digital design software, it currently cannot integrate with the calculation data of structural design software. When designing using CAD or Revit alone, the data is separated from the earlier calculation software such as PKPM or YJK. When modifying the design, it is necessary to maintain two sets of data at the same time, which often leads to human error and a lack of data consistency. Summary of the Invention

[0003] The purpose of this invention is to overcome the problem in the prior art where structural calculations and construction drawing component design are usually handled by different personnel, leading to inconsistent data. This invention provides a hybrid building structure design method based on EasyBIM, which utilizes the integrated 2D and 3D features of EasyBIM software to create 3D entities using 2D design methods. It also integrates data with calculation software such as PKPM or YJK. Each structural component can store building information, providing prerequisites for subsequent quantity calculations, construction, and operation and maintenance, and meeting the needs of collaborative cooperation among various disciplines.

However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0054] Example 1

[0055] This invention is a hybrid design method for building structures based on EasyBIM, such as... Figure 1 The diagram shown is a flowchart of the present invention, including architectural CAD drawings, equipment CAD drawings, a building BIM model, and an equipment BIM model completed using initial building data. The design method is as follows: Figure 2 As shown, the process of processing structural models combines the steps of CAD and Revit, and then collaborative design is performed based on EasyBIM, specifically including:

[0056] S1. Based on EasyBIM and structural calculation software, generate a structural model of the building to be designed, specifically including:

[0057] S11. Generate the first structural model of the building to be designed based on the EasyBIM structural modeling module; using CAD or Revit architectural data as a basis, such as Figure 3 The image shown is a CAD diagram of the building data. Based on this building data, a preliminary design is performed in EasyBIM software. Using the structural modeling and drawing / modification modules in EasyBIM software, an EasyBIM model can be quickly created, forming a preliminary EasyBIM structural layout, as shown below. Figure 4 The diagram shown is a schematic of the structural modeling module. Figure 5As shown, these are the function buttons for the drawing / modification module. The EasyBIM structural modeling module provides a rich set of structural components, such as structural grids, structural columns, structural beams, structural walls, structural slabs, structural cantilever slabs, structural stairs, horizontal haunches, vertical haunches, structural column caps, folded plates, hanging pits, beam openings, wall openings, rectangular slab openings, polygonal slab openings, and circular slab openings, meeting the drawing and modeling needs of structural designers. The drawing / modification module provides structural designers with drawing and editing functions for lines, polylines, arcs, circles, ellipses, moving, copying, rotating, mirroring, stretching, scaling, aligning, trimming, and chamfering, helping them complete the initial structural layout more quickly and flexibly. For example... Figure 6 The diagram shown is a schematic diagram of the structural layout of the first structural model.

[0058] S12. The EasyBIM-based pre-processing module imports the first structural model into the structural calculation software and obtains a structural calculation model containing the calculation results, such as... Figure 7 The image shown is a schematic diagram of a structural calculation model in structural calculation software. Figure 8 As shown, this is the preprocessing module for computation.

[0059] S13. Import the structural calculation model into EasyBIM's structural plan module to construct a second structural model. After the structural calculation software performs the calculations, import the structural calculation model containing the calculation results into EasyBIM using the model import function of the EasyBIM structural plan module to establish a second structural model, as shown below. Figure 9 The diagram shows the structural planar module. Model association settings are required before importing the model. Click the association settings button in EasyBIM and select the calculation model to be associated. Next, click the model import button to import the calculation data from the structural calculation model into the first structural model.

[0060] S14. Using the EasyBIM-based reference management module, select the grid drawing and import it into the second structural model to generate the structural model, as shown below. Figure 10As shown in Figure 11, which is a schematic diagram of the structural model, the structural designer first needs to click the "Reference Management" button. At this point, a reference management panel will pop up on the left side of the software. The structural designer can switch to the DWG reference management panel by selecting "DWG Reference." Then, clicking the "Attach" button will import the selected grid drawings into EasyBIM. The grid drawings are created when the architectural and mechanical engineering disciplines use CAD software for 2D design, utilizing initial CAD architectural data to draw architectural and mechanical CAD drawings, and creating a CAD-based grid base map. Additionally, the architectural and mechanical engineering disciplines use Revit software to construct architectural and mechanical BIM models, creating grid views of the architectural BIM models. Then, the grid views of the architectural BIM models are exported as CAD drawings using Revit's "Export CAD Drawings" function, thus converting them into grid drawings. The structural model includes calculated data and architectural grids. The calculated data includes structural design parameters, cross-sectional dimensions, and reinforcement. The architectural grids include the grid base map from the architectural CAD drawings and the grid views from the architectural BIM model.

[0061] S2. Based on the structural model, perform two-dimensional and three-dimensional design, and utilize EasyBIM for two-dimensional and three-dimensional design data generation; during the two-dimensional and three-dimensional design processes, after updating the architectural CAD drawings, equipment CAD drawings, architectural BIM models, and equipment BIM models, based on EasyBIM's overloaded reference management module, synchronize the updating of architectural and equipment data by overloading all references. Figure 12 The diagram shown illustrates all references to the overloaded reference. The two-dimensional design data is generated by exporting the structural model's plan layout view and structural wall / column base plan using EasyBIM, which are then fed back to architectural and equipment CAD drawings for architectural and equipment design. Figure 13 The diagram shown is a schematic of the floor plan layout. The 3D design data is generated by using the EasyBIM plugin to convert the structural model into a Revit model, then using the structural work data view to extract structural component information from the Revit model, and feeding this information back to the building BIM model and equipment BIM model. Figure 14 The diagram shown is a schematic representation of the working view of the structure.

[0062] S3. After the design is completed, the structural component information of the structural model, including slabs, beams, walls, columns, stairs, etc., is exported based on EasyBIM and fed back to the architectural construction drawings and equipment construction drawings. Specifically, this includes:

[0063] S31. Export the structural component information as CAD drawings using the floor plan view in EasyBIM;

[0064] S32. Convert the structural model into a Revit model using the EasyBIM plugin, and export the component information using the structural work data view and the structural drawing data view;

[0065] S33. Based on the CAD drawings, structural working reference views, and structural output reference views, complete the architectural construction drawing design and equipment construction drawing design.

[0066] S4. Based on EasyBIM, design structural construction drawings for the structural model, specifically including:

[0067] S41. Based on EasyBIM, create structural plan layout views, structural foundation plan views, structural stair plan views, and structural ramp plan views of the structural model, and perform construction drawing design for each, resulting in structural plan construction drawings, foundation construction drawings, stair construction drawings, and ramp construction drawings; (e.g.) Figure 16 The image shown is a plan view of the staircase structure, as follows: Figure 17 The image shown is a plan view of the aforementioned ramp structure.

[0068] S42. Using EasyBIM and referring to the structural plan layout view, select view templates for different component drawings to form slab construction drawings, beam construction drawings, wall construction drawings, and column construction drawings, and perform reinforcement design for slabs, beams, walls, and columns. For example... Figure 18 The image shown is a schematic diagram of a view template list. Figure 19 The diagram shows the components, labels, and information contained in each view.

[0069] This step allows for view template settings to be applied to different component drawings to meet the drawing requirements of various components. During the referencing process, common concepts shared by the EasyBIM structural wall and column base view, CAD structural wall and column base view, EasyBIM structural plan base view, and CAD structural plan base view are uniformly set. Specifically, this includes settings for "layers," "line types," "fill patterns," "text and fonts," "colors," and "annotation styles." This ensures that the CAD element control requirements of traditional 2D design are met, allowing EasyBIM-exported CAD drawings to undergo subsequent drawing refinement or direct printing. Furthermore, when designers need to refine component drawings using existing details and annotations, these component drawings can be exported using EasyBIM's CAD drawing export function. Then, by referencing the EasyBIM component drawings to the CAD software using CAD referencing, existing details, annotations, and title blocks can be added for drawing production. Furthermore, when designers need to use existing drawing resources for design, they can export EasyBIM drawings and refer to them in CAD for detailed design. This allows for efficient component design and review using EasyBIM, while also enabling the reuse of existing design resources, thus simultaneously meeting the requirements of collaborative design and improved efficiency.

[0070] Preferably, during the above design process, EasyBIM's export function can be used to export the structural working reference view and the structural drawing reference view as CAD drawings, thereby providing information to CAD software. The structural working reference view includes information on slab components, beam components, wall components, column components, stair components, slab elevation markings, and opening markings. The structural drawing reference view includes information on wall components and column components.

[0071] Furthermore, EasyBIM also includes a review and annotation module. During the design process, these modules provide designers, proofreaders, reviewers, and approvers with fully accessible quality control and review pathways. Figure 20 The image shown is a schematic diagram of the standardized review results from the review module. Figure 21 The diagram shown illustrates the annotation module. In this step, this method directly integrates technology and quality control throughout the entire structural design process, unlike traditional design methods that only involve checking, reviewing, and approving construction drawings after drafting is completed. In this method, designers, checkers, reviewers, and approvers directly control the structural design through EasyBIM, fully utilizing BIM technology to effectively reduce later design modifications, avoid resource waste, and improve design efficiency and quality.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
