[0040] In the description of the present invention, unless otherwise clearly defined, the words such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more.

[0041] Tekla software is a software package for 3D intelligent steel structure simulation and detailed drawing. Users can build a complete steel structure model in a virtual space. The model includes not only the geometric dimensions of parts, but also material specifications, cross sections, node types, materials, user annotations and other information. When creating a node, you only need to select a node and fill in the parameters, then select the primary and secondary components, and you can query all manufacturing and installation related information at any time. However, the nodes that come with Tekla software are common types, which often do not meet the actual engineering requirements. There are certain limitations in use. When using the nodes that come with the software for modeling, it is necessary to set and store the node parameters of each section, and you need to manually select and read. It is easy to cause modeling errors due to wrong selections, and it takes a certain amount of time to read and convert back and forth, which is inefficient. During the modeling process, when the node needs to be modified, it is necessary to modify the engineering information of each node. The operation is cumbersome, the work efficiency is low, and it is easy to make mistakes.

[0042] Refer to the following Figures 1 to 6 A node modeling method, device and storage medium are described, which can be used for parameterized modeling of nodes with high modeling efficiency.

[0043] Reference Figure 1The node modeling method of the first aspect of the present invention comprises the following steps:

[0044] S100, establishing a three-dimensional model, wherein the three-dimensional model includes steel columns, steel beams and node structures, and the node structures are used to connect the steel columns and the steel beams;

[0045] S200, obtaining a node parameter source file, wherein the node parameter source file is generated according to the node parameters;

[0046] S300, binding the three-dimensional model with the node parameter source file to obtain a node component, wherein the node component can be called by Tekla software to identify steel columns and steel beams in the model to be processed, and used to model and generate corresponding node structures. Modifying the node parameter source file can modify the node structure generated by the model to be processed.

[0047] Since an associative binding relationship is formed between the three-dimensional model and the node parameter source file, the node structure generated by the node component can be modified by modifying the node parameters in the node parameter source file.

[0048] By setting a node structure between steel columns and steel beams in the three-dimensional model and setting a node parameter source file, each node parameter in the node parameter source file can reflect the engineering information of each node structure, and the three-dimensional model and the node parameter source file are linked and bound. When the finally generated node component is applied to Tekla software, Tekla software can automatically identify the steel columns and steel beams in the model to be processed, and visually generate the corresponding node structure in the model to be processed, the modeling efficiency is high, and all node structures can be modified at the same time by modifying the node parameters in the node parameter source file. The adjustment operation is convenient, and there is no need to modify the node structure one by one, which reduces repetitive work.

[0049] It can be understood that the node structure includes a connecting plate, a double supporting plate, a seismic rib plate, bolts, cutouts and cut corners, and the above-mentioned node structure is used to connect steel columns and steel beams.

[0050] It is understandable that, referring to Figure 2 , step S200, obtaining a node parameter source file, including:

[0051] S210, establish a steel warehouse;

[0052] S220. Set the node parameter source file according to the steel material library.

[0053] It is understandable that, referring to Figure 3 , step S220, setting the node parameter source file according to the steel beam library, including:

[0054] S221. According to each steel material data in the steel material library, multiple groups of node parameters are set, wherein each steel material data corresponds to a group of node parameters, and the steel material library includes multiple steel material data;

[0055] S222, generating a node parameter source file according to each steel material data and the node parameters corresponding to each steel material data, wherein the node parameter source file includes multiple groups of discrimination data, each group of discrimination data corresponds to one steel material data and one group of corresponding node parameters, for details, please refer to Figure 6 Example content, each row of data is a set of discriminant data, Figure 6 Eight groups of discrimination data are provided, each group of discrimination data includes the following information: section, bolt standard, bolt size, horizontal margin, horizontal distance column, vertical margin, vertical distance column, connection plate thickness, allowable error, number of columns, column spacing, number of rows-1, row spacing, welding gap.

[0056] After the node parameter source file is preset, when the node component is called for modeling through Tekla software, there is no need to set the node parameters every time. Tekla software can directly use the node component to generate the node structure between the steel column and the steel beam. The operation is simple and the visually displayed node structure can facilitate the user to adjust the node parameters. When the node structure needs to be modified, only some node parameters need to be modified. The modification operation is convenient and intuitive.

[0057] Specifically, the steel material library includes multiple steel material data, including steel column data and steel beam data, the steel column data includes the cross-sectional information and material information of the steel column, and the steel beam data includes the cross-sectional information and material information of the steel beam, that is, the steel material data is used to indicate the cross-sectional type and cross-sectional size of the steel material. Tekla software comes with a profile library, and a steel material library can be generated based on the profile library that comes with Tekla software.

[0058] It is understandable that, referring to Figure 4 , step S300, binding the three-dimensional model with the node parameter source file to obtain a node component, including:

[0059] S310, obtaining engineering information of the three-dimensional model, wherein the Tekla software can directly use the engineering information to establish the three-dimensional model;

[0060] S320, setting a binding relationship;

[0061] S330. According to the binding relationship, the engineering information of the three-dimensional model and the node parameters of the node parameter source file are bound to obtain a node component, wherein the node component can be directly called by Tekla software to identify the steel columns and steel beams in the model to be processed, and used for modeling and generating the corresponding node structure.

[0062] Since the node parameters are bound to the 3D model, the node structure in the generated 3D model can be modified directly by modifying the node parameters. When modifying a large number of node structures, the node parameters in the node parameter source file can be directly modified. There is no need to select the node structure one by one for modification through the Tekla software, and the batch modification operation is convenient.

[0063] Specifically, the binding relationship includes a data binding relationship and a formula binding relationship. Data binding is to set a fixed positioning binding relationship between the project information and the corresponding node parameters. Formula binding is to set a dynamic positioning binding relationship between the project information and the corresponding node parameters.

[0064] It is understandable that, referring to Figure 5 After step S300, the three-dimensional model is bound to the node parameter source file to obtain the node component, and the following steps are also included:

[0065] S400, import node components into Tekla software;

[0066] S500. Select node components through Tekla software, and model and generate corresponding node structures according to the steel columns and steel beams in the model to be processed, wherein the node structure is used to connect the steel columns and steel beams in the model to be processed.

[0067] Specifically, after selecting node components through Tekla software and modeling and generating corresponding node structures according to the steel columns and steel beams in the model to be processed, it also includes:

[0068] Modify the node parameter source file to update the node structure generated by the model to be processed.

[0069] Since the node component is obtained by binding the 3D model with the node parameter source file, all node structures can be modified at the same time by modifying the node parameters in the node parameter source file. The adjustment operation is convenient and there is no need to modify the node structure one by one, which reduces repetitive work. After the node structure is generated according to the model to be processed, the user can be provided with an intuitively displayed node structure, which is convenient for the user to perform modification operations.

[0070] The following describes the node modeling method in combination with specific applications:

[0071] Establish an axis grid and build a three-dimensional model including steel columns, steel beams and node structures.

[0072] A steel material library is generated according to a plurality of steel material data, a plurality of groups of node parameters are set according to each steel material data in the steel material library, and a node parameter source file is generated according to the steel material data and the node parameters, wherein the node parameter source file is a dat file.

[0073] The engineering information of the 3D model is obtained, and the binding relationship between the node parameters and the corresponding engineering information is obtained according to the engineering information and the node parameters. The connecting plates, double support plates, seismic stiffeners, bolts, cutouts and cut corners are positioned and bound according to the binding relationship, and the node components that form an associated binding relationship with the node parameter source file are obtained. The node components are specifically UEL files, which can be used to intelligently create nodes. The node editing page is used to adjust the node parameters in the node parameter source file in the development environment of the Tekla software.

[0074] After starting the Tekla software, import the node components and choose whether to adjust the node parameters in the node parameter source file according to actual needs; after selecting the node components in the Tekla software, batch select the steel columns and steel beams in the model to be processed. The Tekla software can automatically identify the selected steel columns and steel beams, and select the node parameters of the corresponding group in the node parameter source file according to the identification results. Since the engineering parameters of the three-dimensional model have been bound to the node parameters of the node parameter source file, the Tekla software can model and generate the corresponding node structure based on the corresponding node parameters. The node structure is used to connect the selected steel columns and steel beams, thereby realizing parametric modeling. During the development process, if the node structure needs to be modified, the node parameters in the node parameter source file can be modified to modify all the node structures generated above, and the modification operation is convenient.
