Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a barrier-free ramp design method and device based on BIM technology. Background Art

[0002] Accessibility design is an important part of architectural design. In recent years, as the demand for barrier-free facilities has gradually increased, ramps, as a key link in barrier-free facilities, play a vital role in architectural design, especially for the elderly and disabled people with limited mobility. Traditional barrier-free ramp design methods often rely on manual modeling and layout. Designers need to adjust the slope, width, length and materials of the ramp one by one, which is time-consuming and prone to errors.

[0003] In addition, with the development of building information modeling (BIM) technology, the construction industry has gradually shifted from two-dimensional graphic design to three-dimensional building information modeling design, but the existing barrier-free ramp design tools are not highly integrated in BIM technology and cannot give full play to the advantages of BIM technology. Specifically, the design of barrier-free ramps must not only consider the aesthetics of the building, but also ensure that they meet the design requirements of the specifications, such as parameter restrictions on slope and width. The existing BIM forward design basically uses the "ramp" function built into the software for modeling, defines the location of the barrier-free ramp, manually adjusts the slope and width parameters of the barrier-free ramp, and then exports the plane, section or required detailed drawings. This design method is not only time-consuming and labor-intensive, but also prone to human operation resulting in non-compliance with the specifications. For example, the slope, width, length and other parameters of the ramp need to be precisely controlled according to relevant specifications, and manual operation may not be able to accurately meet the requirements. At the same time, the traditional design method is difficult to adjust the overall layout in the early stage of the design, and often requires continuous modification of the design during the later construction process, affecting the construction progress and engineering costs.

[0004] Although some design software such as AutoCAD can achieve partial automation through simple parametric modeling, these software have limitations in the application of barrier-free design and cannot fully utilize BIM technology for intelligent design. At the same time, existing barrier-free design tools are usually not integrated into the building information model (BIM) platform, resulting in a disconnect between design and construction information and increasing communication costs during the design and construction process.

[0005] In summary, the existing barrier-free ramp design methods have problems such as low design efficiency, large errors, disconnection between design and construction information, and difficulty in ensuring design standardization. There is an urgent need for a more efficient, accurate and standardized barrier-free ramp design method. Summary of the invention

[0045] The technical solution of the present invention is described below in conjunction with the accompanying drawings.

[0046] In the embodiments of the present invention, words such as "exemplarily" and "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "example" in the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the word "example" is intended to present the concept in a specific way. In addition, in the embodiments of the present invention, the meaning expressed by "and / or" can be both, or it can be either of the two.

[0047] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0048] The embodiment of the present invention provides a barrier-free ramp design method based on BIM technology. Figure 1 The flowchart of the barrier-free ramp design method based on BIM technology is shown. The processing flow of the method may include the following steps:

[0049] Among them, BIM (Building Information Modeling) is a technology that integrates all relevant information data of a construction project into a three-dimensional model and simulates the real information of the building through digital information simulation. BIM software is a tool for creating and managing digital representations of construction projects, which allows designers, engineers, architects and other professionals to work together.

[0050] 100. Establish a component library for barrier-free ramps, which includes straight ramps, curved ramps and zigzag ramps.

[0051] Among them, the component library is a database or resource library that collects a variety of predefined and reusable components. These components can simplify the design, development or manufacturing process and can be reused in different projects or systems.

[0052] A linear ramp goes up or down in a straight line. This type of ramp is suitable for shorter distances or when you need to directly connect two surfaces at different heights.

[0053] Curved ramps allow for smoother transitions of height differences in larger spaces, providing a better visual and physical experience, and can be used for longer ramps or in scenarios where space usage needs to be optimized.

[0054] A zigzag ramp consists of multiple straight segments connected at acute or obtuse angles. This design can provide the necessary vertical height change within a limited space while allowing more design flexibility.

[0055] In this step, each type of ramp component may have different size, material, design and other options to meet different scenarios and needs.

[0056] The component library enables designers to quickly select and use the appropriate ramp type, reducing the time it takes to design each ramp from scratch. The component library provides a variety of ramp types, and designers can flexibly choose according to project requirements. This step improves design efficiency and enhances design flexibility.

[0057] 200. Integrate the component library into the BIM software through the API interface.

[0058] API (Application Programming Interface) is a software interface that allows different software programs to communicate with each other.

[0059] In this step, the component library established earlier is integrated with the BIM software using the API interface, and seamless data transmission and interaction are achieved through the API interface. In this way, designers can use these component libraries directly in the BIM software to design barrier-free ramps without manually importing or converting data. This step involves integrating the component library with the BIM software.

[0060] The integrated component library enables designers, engineers and other relevant personnel to work together on the same platform, improving design efficiency and quality. Designers can complete the design of the ramp in the BIM environment without switching between multiple software. This step promotes design collaboration and simplifies the design process.

[0061] 300. According to the ramp type, obtain the target component from the component library.

[0062] When designing an accessible ramp, you first need to determine the type of ramp you need. Then, based on this type, retrieve the corresponding target component from the component library. This step ensures that the selected component is consistent with the required ramp type.

[0063] This step avoids the problems of inaccurate size or mismatched shapes caused by manually drawing the ramp, reduces design errors and improves the accuracy of the design.

[0064] 400. According to the layout position, obtain surrounding environmental factors, and adjust the parameters of the target component based on the environmental factors.

[0065] This step combines the target component with the surrounding environment to obtain the factors in the environment that restrict the ramp. Designers can determine the optimal location of the ramp and adjust the parameters of the target component based on the actual situation of the project, such as terrain, building layout, and traffic flow, to ensure that the barrier-free ramp meets functional requirements and does not interfere with the surrounding environment. The rationality of the layout helps reduce obstacles during the construction process and improve the feasibility and practicality of the project.

[0066] 500. Adjust the parameters of the target component according to the slope, width, length and material to determine the ramp family.

[0067] In this step, the parameters of the target component are adjusted to meet the needs of a specific project. After the parameter adjustment is completed, a specific ramp family can be determined, which represents a ramp type with specific properties and characteristics.

[0068] The parametric design of the present invention can accurately adjust the design results, avoid errors in traditional design methods, and improve the safety of the design.

[0069] 600. Verify the ramp family based on the preset specification parameters.

[0070] The preset specification parameters may include building design specifications. After the ramp family is determined, it needs to be verified to ensure that it meets the preset specification parameters. These specification parameters may include slope restrictions, width requirements, anti-slip performance standards, and material durability standards. The verification process will ensure that the ramp design is both safe and practical, and complies with relevant regulations and standards.

[0071] Furthermore, the preset specification parameters may also include safety standards, relevant laws and regulations, etc. Through the verification of this step, potential safety hazards can be reduced and the safety and compliance of the design can be improved.

[0072] 700. Generate the verified ramp family into a ramp model.

[0073] Specifically, the function of BIM software can be used to convert the ramp family into a 3D model so that designers, engineers and construction teams can intuitively view and understand the design of the barrier-free ramp. This model will serve as a reference for subsequent construction and installation.

[0074] By generating a 3D model, designers can intuitively view the design effect of the ramp, which helps to identify potential problems and make improvements, and improves the visualization of the design. The 3D model can be used as a design communication tool to help designers communicate more effectively with other relevant personnel (such as construction personnel, owners, etc.).

[0075] The barrier-free ramp design method based on BIM technology provided by the embodiment of the present invention enables designers to quickly select and use suitable ramp types and reduce design time by setting a component library. The component library provides a variety of ramp types, which can be flexibly selected according to project requirements. This step improves design efficiency and enhances design flexibility. By integrating into the BIM platform, design information can be seamlessly transferred to the construction stage, reducing the communication cost between design and construction. Moreover, the integrated component library realizes design collaboration and simplifies the design process. Through parametric design, the parameters of the target component can be adjusted, the design results can be accurately adjusted, errors in traditional design methods are avoided, and the safety of the design is improved. Through the verification process, it can be ensured that the design of the ramp complies with the building design specifications.

[0076] Furthermore, the implementation of the present invention helps to promote the construction and improvement of barrier-free facilities, increase society's attention and care for the elderly and people with mobility difficulties, and has positive social significance.

[0077] In one embodiment provided by the present invention, step 100 includes:

[0078] 110. Set the geometry, size range, material type and installation requirements of each component.

[0079] Specifically, the component library includes straight ramps, curved ramps and broken line ramps. The geometric shape of each ramp component can be determined according to the principles of barrier-free design and actual needs. This includes the ramp's inclination angle, curve radius, turning point, etc., to ensure that the component can meet the basic requirements of barrier-free passage.

[0080] In order to adapt to the application requirements in different scenarios, a reasonable size range can be set for each component. The size range can comprehensively consider factors such as ergonomics, traffic flow, space constraints, etc. to improve the practicality and aesthetics of the ramp.

[0081] The material types of barrier-free ramps can be concrete, steel, wood or synthetic materials.

[0082] The installation requirements of components include fixing methods, connection nodes, etc.

[0083] Based on this step, a comprehensive component library is built to shorten the design cycle in the future. Multi-dimensional design enhances design flexibility, and designers can flexibly combine and adjust according to project requirements to meet diverse accessibility needs.

[0084] In one embodiment provided by the present invention, step 200 includes:

[0085] 210. Based on the API interface of Revit software, the component library is integrated into Revit software.

[0086] Revit is a BIM software that provides a rich API interface, allowing developers to interact with Revit through programming. Based on these API interfaces, we can integrate the component library we established previously into the Revit software.

[0087] Specifically, in this step, you can use Revit's API interface to develop a plug-in that can read and parse component library data. This plug-in is used to import component information in the component library into Revit and make it available in the Revit interface. Install the developed plug-in into Revit and perform necessary configuration. This usually includes setting the loading path of the plug-in, configuring the parameters of the plug-in, etc., and then you can access and use the components in the component library through the plug-in in Revit.

[0088] This step can greatly shorten the design cycle and enhance design flexibility. Using a standardized component library helps ensure design consistency and accuracy.

[0089] Figure 2 This is the second flowchart of a barrier-free ramp design method based on BIM technology provided by an embodiment of the present invention. Figure 2 In an embodiment provided by the present invention, after step 200, the method further includes:

[0090] 800. Output a user interaction interface, where the user interaction interface is a graphical interface.

[0091] Specifically, the graphical interface usually includes various elements such as buttons, menus, text boxes, etc., through which users can interact with the system. In an embodiment of the present invention, this graphical interface is used to interact with the component library in the Revit software, so that users can easily browse, select and adjust components.

[0092] The graphical interface makes operation more intuitive and simple, with strong interactivity. The intuitive interface design reduces the time required for users to find and select components, thereby improving design efficiency.

[0093] 900. Read operation information in response to a click and input operation on a user interaction interface.

[0094] When the user clicks and inputs operations through the graphical interface, the system or software will capture these operation information in real time. This information includes the buttons clicked by the user, the menu items selected, the text entered, etc. In the embodiment of the present invention, this information is used to determine which component the user wants to adjust and how to adjust it.

[0095] 1000. Based on the operation information, the ramp type, layout location, slope, width, length and material are obtained.

[0096] After obtaining the user's operation information, the system or software will subsequently adjust the parameters of the target component according to this information. In an embodiment of the present invention, the system will automatically update the parameters of the corresponding component in the Revit model according to the user's operation on the graphical interface.

[0097] This step can assist designers in achieving dynamic design. That is, users can adjust component parameters in real time through a graphical interface, see changes in design effects, and perform iterations and optimizations.

[0098] In one embodiment provided by the present invention, the specification parameters include slope restrictions, width requirements, anti-slip performance standards and material durability standards.

[0099] Among them, the slope limit usually refers to the normative requirements for the size of the slope to avoid safety hazards caused by too steep slopes. The width requirement ensures that there is enough space for people to pass safely.

[0100] The anti-slip performance standard refers to the anti-slip performance of the surface material in wet or slippery conditions. The anti-slip performance standard ensures that pedestrians can walk safely in all weather conditions and avoid accidents caused by slips.

[0101] Material durability standards refer to the durability of the materials used under long-term use and environmental factors (such as wind, rain, temperature changes, etc.). Material durability standards ensure the long-term stability of the project and reduce maintenance costs.

[0102] In an embodiment provided by the present invention, after step 700, the following steps are further included:

[0103] 1100. Place the generated ramp model to a preset location in the building project.

[0104] The preset position may be specified by the user in the GUI by clicking, dragging or other interactive methods. Further, the preset position may also be determined by reading coordinate information provided by a project file, a database or an API interface.

[0105] This step is used to add the generated ramp model to the original building project model to facilitate overall viewing and ensure overall consistency and functionality.

[0106] In an embodiment provided by the present invention, after step 700, the following steps are further included:

[0107] 1200. Export the construction drawings of the ramp model.

[0108] The construction drawings of the ramp model can be exported using CAD (computer-aided design) software or other professional 3D modeling software, such as AutoCAD, Revit, SketchUp, etc. This step is to facilitate construction

[0109] Figure 3 This is the third flowchart of a barrier-free ramp design method based on BIM technology provided by an embodiment of the present invention, please refer to Figure 3 In one embodiment provided by the present invention, step 600 includes:

[0110] 610. Verify that the ramp design complies with preset building codes and barrier-free design standards.

[0111] This step is used to ensure that the ramp design not only meets basic architectural requirements, but also adheres to the principles of barrier-free design so that it can be used safely and conveniently by everyone.

[0112] 620. If not compliant, output the non-compliant items.

[0113] This step is used to promptly identify and report design problems so that they can be modified and optimized.

[0114] Furthermore, for each non-conformity, it can also provide specific specification clauses, comparison of design values ​​with actual values, possible consequences, etc. Specifically, reports can be generated or non-conformities can be marked directly in the software so that the design team can quickly identify and take action.

[0115] In one embodiment provided by the present invention, after step 700, the following steps are further included:

[0116] 1300. Use the conflict detection function of BIM software to check whether there is any conflict between the ramp model and other building elements.

[0117] Through this step, the conflict detection function of the BIM software can be effectively used to check whether there is a conflict between the ramp model and other building elements, and make modifications and optimizations in a timely manner.

[0118] In this embodiment, the parametric modeling of barrier-free ramp components is performed through the API interface in the BIM software, and different types of ramp components such as straight ramps, curved ramps, and broken line ramps are created. Then, the modeled ramp components are saved in the family library to form a complete ramp family library system, which is convenient for users to call in the project. Finally, the user can select the ramp type and placement position through the interface provided by the system, and input the relevant parameters of the ramp. The system will automatically generate a ramp model and arrange it. Through the above process, the present invention can complete the design and layout of barrier-free ramps in a short time, and ensure compliance with design specifications, greatly improving the design efficiency.

Through the verification process, it can be ensured that the design of the ramp complies with the building design specifications.

[0120] Furthermore, the barrier-free ramp is aging-friendly, providing a safe and convenient passage for groups with limited mobility, such as the elderly and the disabled. The present invention realizes the automatic generation and layout of barrier-free ramps through BIM technology and API interface, greatly improving the design efficiency and reducing the workload of designers.
