[0035] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] The spatial space frame construction method for buildings proposed in this invention addresses the difficulty of manually constructing building space frames. It involves obtaining the upper and lower chord surfaces of the target building, defined by the roof surface as a reference plane; using column grid dimensions, upper chord grid dimensions, and lower chord grid dimensions as input data for a parametric model; dividing the upper and lower chord surfaces into a space frame structure within the parametric model to obtain upper and lower chord members and their corresponding column node group vectors; performing cross operations on the column node group vectors corresponding to the upper and lower chord members to obtain the space frame web members; and constructing the spatial space frame of the target building based on the upper and lower chord members and the space frame web members. In this application, a parametric model is used to divide the upper and lower chord surfaces into a space frame structure, obtaining the upper and lower chord members and their corresponding column node vectors to obtain the space frame web members. Then, based on the upper and lower chord members and the space frame web members, the spatial space frame of the target building is constructed. Compared with the prior art, the entire process can be automatically performed by the parametric model and the corresponding software system, without the need for manual construction. This helps to reduce material waste caused by manual construction and improve the performance of the constructed space frame structure.

[0037] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0038] Figure 1 This is a flowchart illustrating a method for constructing a spatial grid structure for a building, according to an exemplary embodiment. Figure 1 As shown, the spatial grid construction method for buildings proposed in this embodiment of the invention includes:

[0039] Step 10: Obtain the upper and lower chord surfaces of the target building, defined by the roof surface as the reference plane;

[0040] Step 11: Using the column grid size, upper chord grid size, and lower chord grid size as input data for the parametric model, perform grid structure division on the upper and lower chord surfaces within the parametric model to obtain the upper and lower chord members and the corresponding column node group vectors;

[0041] Step 12: Perform cross-operation on the column node group vectors corresponding to the upper and lower chords to obtain the web members of the space frame;

[0042] Step 13: Based on the upper and lower chords and the web members of the space frame, construct the spatial space frame of the target building.

[0043] In this exemplary embodiment, the parameterized modeling function can generate parameters based on the building's shape and grid size information, producing upper and lower chords and their corresponding column node vectors. A column node refers to the connection point where chords intersect in a frame structure. The column grid size is the distance between two adjacent column nodes. The upper chord grid size refers to the overall size of the upper chord grid. The lower chord grid size refers to the overall size of the lower chord grid. The column node vector is used to characterize the extension direction of the chords between column nodes.

[0044] In this exemplary embodiment, after obtaining the spatial grid of the target building, it can be imported into structural design finite element analysis software in the form of CAD lines for spatial grid calculation and analysis.

[0045] In this application, a parametric model is used to divide the upper and lower chord surfaces into a space frame structure, obtaining the upper and lower chord members and their corresponding column node vectors to obtain the space frame web members. Then, based on the upper and lower chord members and the space frame web members, the spatial space frame of the target building is constructed. Compared with the prior art, the entire process can be automatically performed by the parametric model and the corresponding software system, without the need for manual construction. This helps to reduce material waste caused by manual construction and improve the performance of the constructed space frame structure.

[0046] In some instances, the parameterized model includes at least a plurality of integrated arithmetic units;

[0047] The parameterized model uses column grid dimensions, upper chord grid dimensions, and lower chord grid dimensions as input data. Within the parameterized model, the upper and lower chord surfaces are divided into a grid structure to obtain the upper and lower chord members and their corresponding column node group vectors, including:

[0048] The upper and lower chord surfaces and column grid dimensions, upper chord grid dimensions and lower chord grid dimensions are entered into the integrated arithmetic unit. By adjusting the column node insertion value and node offset value, the upper and lower chord members of the space frame and the corresponding column node group vectors are generated. The column node insertion value refers to the distribution density or position of the column nodes between the upper and lower surfaces; the node offset value refers to the displacement of the column nodes in the horizontal or vertical direction.

[0049] In this exemplary embodiment, the parametric model has a plug-in extension function, which can be equipped with a built-in secondary development arithmetic unit. This arithmetic unit has the function of storing and processing data. By connecting different arithmetic units with different calculation rules, a complete set of command groups with programming logic can be formed. At the same time, the parameter adjustment process and results can be dynamically displayed in real time on the model interface, and the calculation data of the entire process can be completely saved. By adjusting the column node insertion value and node offset value, the upper and lower chords of the space frame and the corresponding column node group vectors of the upper and lower chords can be generated. The column node insertion value refers to the distribution density or position of the column node between the upper and lower surfaces; the node offset value refers to the displacement of the column node in the horizontal or vertical direction. It can be exported to the structural design finite element analysis software through CAD mode or text file mode, so that the model with parametric modeling function and the software with structural calculation and analysis function can be accurately connected to form an integrated collaborative working model.

[0050] In some instances, obtaining the upper and lower chord surfaces of the target building, defined using the roof surface as a reference plane, includes:

[0051] Using the building roof surface as a reference surface, an offset distance is made to form an upper chord surface and a lower chord surface; wherein, the offset distance includes a first offset distance for forming the upper chord surface and a second offset distance for forming the lower chord surface.

[0052] In some instances, the first offset distance is the roof thickness; the second offset distance is the height of the space frame.

[0053] The curved space frame (planar truss) structural model established based on the above parametric method has a high degree of consistency with the building surface. Furthermore, key parameters such as the height of the curved space frame (planar truss) and the size of the structural grid can be adjusted in real time to conduct comparative analysis of multiple schemes, so as to strictly control the amount of steel used and the structural stress performance of the project.

[0054] This application not only avoids the difficulties and inaccuracies in form finding in traditional architectural design, which can lead to collisions between designed components during actual construction, but also allows for the generation of new structural geometric and computational models simply by re-importing the architectural model surfaces after adjustments to the architectural scheme. This eliminates the need for manual remodeling, significantly improving design efficiency, avoiding a large amount of repetitive work, and playing a positive role in the parametric design of space frame structures.

[0055] In this application, a mathematical logic-based visual programming language can be used to design and interact in real-time with 3D modeling software, enabling the optimization of parametric space frame designs. Adjustable parameters are added during this process to make the design more rational.

[0056] Simultaneously, the visual programming language is linked with the 3D modeling software in real time, enabling real-time visualization and interaction during the design process. Parameters can be adjusted in the visual programming language, and the changes in the design are immediately visible in the 3D modeling software. This real-time linkage allows for a better understanding of the design's effects and facilitates necessary adjustments and optimizations. To increase adjustable parameters, sliders, input boxes, or other interactive controls are used in the visual programming language to adjust design parameters. This approach helps us better understand and optimize the design to meet different design requirements and constraints.
