The 3D steel structure model is a millimeter-level digital model that can provide users with accurate parameters and data. It can be used as an important basis for guiding the production and installation of steel structure parts and the settlement of steel structure project quantities. Using 3D modeling technology to carry out in-depth design of steel structures is an important part of the application of BIM technology in steel structure engineering projects, and it is also an important process for realizing the informatization and industrialization of steel structure engineering projects.

[0003] The connection nodes of the main beam and the secondary beam are often encountered in the detailed design of steel structures. There are often a large number of connection nodes of the main beam and the secondary beam in a steel structure project. The node style will change with the cross-sectional size of the main beam and the secondary beam, and the node changes are more. For steel structure detailed design engineers, manually creating such connection nodes requires first determining the connection parameters of the nodes according to the different main beam and secondary beam cross-sections, and then completing the modeling of the main beam, secondary beam and connection nodes. This modeling efficiency is low, the speed is slow, and the modeling accuracy is low.

[0044] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application embodiments can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application embodiments, some technical features well known in the art are not described.

[0045] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.

[0046] Herein, ordinal numbers such as “first” and “second” cited in this application are merely identifiers and do not have any other meanings, such as a specific order or the like.

[0047] In order to thoroughly understand the implementation of the present application, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present application is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the present application is described in detail below, but in addition to these detailed descriptions, the present application may also have other implementations.

[0048] The present application provides a modeling method based on the Tekla platform. The method can be implemented on the Tekla platform to quickly create a model of a connected (hinged) secondary beam 120 and a main beam 110. The secondary beam 120 includes a secondary beam web 121, a secondary beam upper wing plate 122, and a secondary beam lower wing plate 123. The main beam 110 includes a main beam web 111, a main beam upper wing plate 112, and a main beam lower wing plate 113. The secondary beam 120 and the main beam 110 can both be I-beams or H-beams. It can be understood that in an embodiment not shown, the cross-sections of the secondary beam and the main beam can also be C-shaped, L-shaped, channel steel, or angle steel, etc.

[0049] Please refer to Figures 1 to 3 The secondary beam 120 and the main beam 110 are hinged so that the length direction of the secondary beam 120 intersects (e.g., is perpendicular to) the length direction of the main beam 110. The top surface of the secondary beam 120 and the top surface of the main beam 110 are located in the same plane. The height of the secondary beam 120 is less than or equal to the height of the main beam 110. The secondary beam 120 and the main beam 110 are connected by a connection node. The connection node includes a connection plate 130 and a connection bolt group 140.

[0050] It can be understood that in an embodiment not shown, the center line of the secondary beam and the center line of the main beam are located in the same plane, or the bottom surface of the secondary beam and the bottom surface of the main beam are located in the same plane.

[0051] The modeling method of the present application is applicable to the case where the top surface of the secondary beam is not higher than the top surface of the main beam or the bottom surface of the secondary beam is not lower than the bottom surface of the main beam.

[0052] The modeling method includes the steps of creating a database and creating a parameterized node program for the hinged connection from the secondary beam to the main beam.

[0053] Specifically, creating a database includes: creating a database, wherein the database has correspondingly set cross-sectional shape parameters and connection parameters of the secondary beam, wherein the connection parameters include bolt parameters and connection plate parameters.

[0054] A database is created on the Tekla platform. The database includes cross-sectional shape parameters and connection parameters. The cross-sectional shape parameters represent the cross-sectional shape of the secondary beam 120. The cross-sectional shape parameters can be distinguished by profile specifications. Different profile specifications correspond to secondary beams 120 with different cross-sectional shapes. The connection parameters include bolt parameters and connection plate parameters. The bolt parameters can be used to determine the number of bolts of the connection bolt group 140, the position of the connection bolt group 140 relative to the secondary beam 120, and the specifications of the bolts. The connection plate parameters can be used to determine the thickness and material of the connection plate 130.

[0055] The cross-sectional shape parameters and the connection parameters correspond one to one. The connection parameters corresponding to the cross-sectional shape parameters can be found in the project design drawings, relevant specifications, standards, or predetermined by structural calculation. In this way, the database records the cross-sectional shape of the secondary beam 120, and the parameters of the connection plate 130 and the connection bolt group 140 of the connection node between the secondary beam 120 and the main beam 110.

[0056] The step of creating a secondary beam to main beam hinged parameterized node program includes: creating a model of the main beam 110 and the secondary beam 120 intersecting in the length direction.

[0057] After the database is created on the Tekla platform, the main beam 110 and the secondary beam 120 can be created on the Tekla platform. At this time, the cross-sectional shape of the main beam 110 and the cross-sectional shape of the secondary beam 120 can be determined as needed (for example, according to the requirements of the design drawings). The length direction of the main beam 110 and the length direction of the secondary beam 120 intersect (for example, perpendicularly). At this time, the main beam 110 and the secondary beam 120 have overlapping parts. When the subsequent Tekla platform creates the connection node between the main beam 110 and the secondary beam 120, the secondary beam 120 is automatically trimmed so that there is a gap between the secondary beam end face 124 and the main beam 110.

[0058] The step of creating a secondary beam to main beam articulated parameterized node program also includes: creating a connection node between the main beam 110 and the secondary beam 120, and setting the main beam 110 and the secondary beam 120 at an interval. Specifically, when creating the connection node between the main beam 110 and the secondary beam 120, a gap is set between the secondary beam end face 124 and the main beam 110. The connection node includes a connection plate 130 and a connection bolt group 140. The connection plate 130 is connected to the secondary beam web 121 through the connection bolt group 140, and the connection plate 130 is connected (for example, welded) to the main beam 110.

[0059] Through the cross-sectional shape of the secondary beam 120, the cross-sectional shape parameters and connection parameters corresponding to the cross-sectional shape of the secondary beam 120 are determined according to the database, and the number of bolts, bolt specifications and positions of the connecting bolt group 140, as well as the connecting plate parameters are set according to the connection parameters.

[0060] After completing the creation of the main beam 110 and the secondary beam 120, the system can compare the cross-sectional shape of the secondary beam 120 with the database based on the cross-sectional shape of the secondary beam 120, thereby determining the cross-sectional shape parameters representing the cross-sectional shape of the secondary beam 120, and then determine the connection parameters corresponding to the cross-sectional shape parameters.

[0061] Specifically, after the main beam 110 and the secondary beam 120 are modeled, the parameterized node can be used to create the connection node. The parameterized node first uses a query function in the database to query the model and specification of the cross-sectional shape of the connection node to be created, thereby obtaining connection parameters that match the model and specification of the current cross-sectional shape. The connection parameters include the aforementioned bolt parameters and connection plate parameters.

[0062] The connection plate 130 and the connection bolt group 140 of the connection node between the secondary beam 120 and the main beam 110 are created on the Tekla platform. The connection plate 130 is connected to the secondary beam web 121 through the connection bolt group 140. The connection plate 130 is also connected to the main beam 110. The number of bolts of the connection bolt group 140, the specifications of the bolts, and the position of the connection bolt group 140 relative to the secondary beam 120 can be determined according to the determined connection parameters, and then the connection bolt group 140 is created according to the number of bolts of the connection bolt group 140, the specifications of the bolts, and the position of the connection bolt group 140 relative to the secondary beam 120, and the connection plate parameters are determined according to the connection parameters, and then the connection plate is created (nodes are created), thereby completing the modeling of the connection node from the secondary beam 120 to the main beam 110. Thus, the modeling of the secondary beam 120 and the main beam 110, as well as the connection node, is completed.

[0063] In this embodiment, after creating a database with connection parameters and creating the main beam 110 and the secondary beam 120 on the Tekla platform, the connection parameters corresponding to the current secondary beam 120 can be automatically matched through parameterized nodes, and the connection node from the secondary beam 120 to the main beam 110 can be automatically created, without manually calculating the connection parameters of each connection node of the secondary beam 120, and then creating the connection node between the secondary beam 120 and the main beam 110 on the Tekla platform. The connection node between the main beam 110 and the secondary beam 120 can be created quickly and with high precision.

[0064] Optionally, the connection parameters include at least one of a specification of connection bolts of the connection bolt group, a bolt spacing, a relative position parameter of the connection bolt group and the end surface of the secondary beam, a number of bolt rows, and a number of bolt columns. In this embodiment, the connection parameters include a specification of connection bolts of the connection bolt group, a bolt spacing, a relative position parameter of the connection bolt group and the end surface of the secondary beam, a number of bolt rows, and a number of bolt columns.

[0065] It should be noted that bolts in different columns are arranged at intervals along the length direction of the secondary beam 120. Bolts in different rows extend along the height direction of the secondary beam 120. The relative position parameter of the connecting bolt group and the end face of the secondary beam can be the distance between the axis of the bolt closest to the main beam 110 in the connecting bolt group 140 and the secondary beam end face 124 of the secondary beam 120 close to the main beam 110. Therefore, the number of bolts in the connecting bolt group 140, the specifications of the bolts, and the relative position of each bolt and the end face of the secondary beam 120 along the length direction of the secondary beam 120 can be accurately determined.

[0066] Optionally, refer to Figure 1 , in the Tekla platform, the control handle 141 (a straight line) of the connecting bolt group 140 is made to coincide with the center line of the secondary beam 120. The control handle 141 of the connecting bolt group 140 is the control handle 141 of the connecting bolt group 140 of the Tekla platform, and will not be described here. The control handle 141 of the connecting bolt is perpendicular to the axial direction of the bolt of the connecting bolt group 140. The connecting bolts of the connecting bolt group 140 located on both sides of the control handle 141 are symmetrically arranged. By coinciding the control handle 141 of the connecting bolt group 140 with the center line of the secondary beam 120, the position of the connecting bolt group 140 relative to the secondary beam 120 along the height direction of the secondary beam 120 can be determined. The center line of the secondary beam 120 is parallel to the length direction of the secondary beam 120 and extends through the center of the cross-sectional shape of the secondary beam 120. In this way, when the cross-section of the secondary beam 120 changes, the position of the connecting bolt group 140 relative to the center line of the secondary beam 120 is fixed (will not change).

[0067] Optionally, the connection parameters include the material and / or thickness of the connection plate 130. Thus, the connection plate 130 can be accurately determined.

[0068] Alternatively, if Figure 1 and Figure 3 As shown, the distance between the connecting bolt group 140 and the upper edge 131 of the connecting plate 130 is the upper distance. The distance between the connecting bolt group 140 and the side edge 133 of the connecting plate 130 away from the main beam 110 is the side distance. The distance between the connecting bolt group 140 and the lower edge 132 of the connecting plate 130 is the lower distance. At least one of the upper distance, the lower distance and the side distance is determined according to the relative position parameter.

[0069] It should be noted that if Figure 1 and Figure 3 As shown, the distance between the axis of the uppermost connecting bolt of the connecting bolt group 140 and the upper edge 131 is the upper distance. The distance between the axis of the connecting bolt of the connecting bolt group 140 farthest from the main beam 110 and the side edge 133 is the side distance. The distance between the axis of the connecting bolt of the lowermost connecting bolt of the connecting bolt group 140 and the lower edge 132 is the lower distance.

[0070] As described above, the database is provided with relative position parameters. Thus, the upper distance, the lower distance and the side distance can be determined according to the relative position parameters. Thus, the shape of the portion of the connecting plate 130 extending between the secondary beam upper wing plate 122 and the secondary beam lower wing plate 123 can be determined.

[0071] Furthermore, the upper distance, the lower distance and the side distance are all equal to the relative position parameter.

[0072] It is understood that in an embodiment not shown, any two of the upper distance, the lower distance and the side distance may be different. In this case, the upper distance, the lower distance and the side distance may be determined respectively according to the relative position parameter by a predetermined rule (for example, the ratio or difference between any one of the upper distance, the lower distance and the side distance and the relative position parameter is a predetermined value).

[0073] Optionally, the connection plate 130 is attached to the secondary beam web 121 of the secondary beam 120. Thus, the connection relationship between the secondary beam 120 and the connection plate 130 can be accurately established.

[0074] Alternatively, if Figure 1 and Figure 3 As shown, the connecting plate 130 extends between the main beam upper wing plate 112 and the main beam lower wing plate 113 of the main beam 110. The connecting plate 130 abuts against at least one of the lower surface of the main beam upper wing plate 112, the upper surface of the main beam lower wing plate 113, and the main beam web 111. In this embodiment, the connecting plate 130 abuts against the lower surface of the main beam upper wing plate 112, the upper surface of the main beam lower wing plate 113, and the main beam web 111. Thus, the connection relationship between the connecting plate 130 and the main beam 110 can be accurately established.

[0075] The dimension of the interval between the secondary beam end face 124 of the secondary beam 120 and the main beam 110 along the length direction of the secondary beam 120 is set to a preset constant. The preset constant can be predetermined. The dimension is the distance between the free end of the main beam upper wing plate 112 or the main beam lower wing plate 113 close to the secondary beam 120 and the secondary beam end face 124 of the secondary beam 120 close to the main beam 110 along the length direction of the secondary beam 120. In this way, when the cross-sectional shape of the main beam 110 changes, the relative position between the secondary beam 120 and the main beam 110 changes accordingly.

[0076] Furthermore, the preset constants corresponding to each secondary beam 120 can be modified independently.

[0077] The preset constants corresponding to each connection node from the secondary beam 120 to the main beam 110 can be modified independently. In the Tekla platform, one or more created connection nodes from the secondary beam 120 to the main beam 110 can be selected by clicking or selecting with the mouse, and the node property dialog box can be activated to modify the preset constants corresponding to the connection node in a personalized manner, thereby achieving the purpose of modifying the created model independently or in batches in the form of points.

[0078] The preset constants of all secondary beams 120 may be uniformly modified to a uniform value.

[0079] The preset constants corresponding to all the connection nodes from the secondary beam 120 to the main beam 110 created in the model can be modified uniformly. In the user component editor of the Tekla platform, the preset constants in the parametric node program can be modified. When the preset constants of the parametric node program are modified and saved, the Tekla platform will automatically update all the connection nodes from the secondary beam 120 to the main beam 110 created in the model, thereby achieving the purpose of uniform modification of the entire model.

[0080] Replace the cross-sectional shape parameters of the secondary beam that has been modeled with another cross-sectional shape parameter in the database, and then refresh the secondary beam and the connection node.

[0081] In the database, the cross-sectional shape parameter of the currently created secondary beam 120 can be replaced with another cross-sectional shape parameter in the database. The system automatically updates the model of the secondary beam according to the new cross-sectional shape parameter. The system updates the corresponding connection parameter according to the new cross-sectional shape parameter, and then updates the connection node corresponding to the secondary beam.

[0082] like Figure 2 As shown, the connection node also includes a stiffening plate 150. The stiffening plate 150 is located on the side of the main beam web 111 of the main beam 110 away from the secondary beam 120, and is connected to the main beam 110. The position of the stiffening plate 150 is set corresponding to the position of the connecting plate 130. Along the length direction of the main beam 110, the stiffening plates 150 and the connecting plates 130 correspond one to one. The positions of the corresponding stiffening plates 150 and the connecting plates 130 along the length direction of the main beam 110 are the same. The materials and thicknesses of the corresponding stiffening plates 150 and the connecting plates 130 are the same. In this way, the connection node between the secondary beam 120 and the main beam 110 can be created more accurately.

[0083] Optionally, please continue to refer to Figure 2 The stiffening plate 150 extends between the main beam upper wing plate 112 and the main beam lower wing plate 113 of the main beam 110, and abuts against at least one of the main beam upper wing plate 112, the main beam lower wing plate 113 and the main beam web 111. Thus, the connection relationship between the stiffening plate 150 and the main beam 110 can be accurately established.

[0084] Furthermore, the outer side surface 151 of the stiffening plate 150 away from the main beam web 111 is flush with the edge of the main beam upper flange 112. Thus, the connection relationship between the stiffening plate 150 and the main beam 110 can be accurately established.

[0085] Optionally, create a node variable A. A = the first node variable value B1 or the second node variable value B2. If A = the first node variable value B1, a connection node is created on one side of the secondary beam web 121 of the secondary beam 120. If A = the second node variable value B2, a connection node is created on the other side of the secondary beam web 121 of the secondary beam 120. Thus, by changing the node variable A, a connection node can be created on one side of the secondary beam 120, which is convenient for operation.

[0086] Optionally, create a stiffening plate variable C. C = first stiffening plate variable value D1, and A = first node variable value B1, then create a stiffening plate 150 on one side of the secondary beam web 121 of the secondary beam 120;

[0087] C=the second stiffener plate variable value D2 , and A=the second node variable value B2 , then a stiffener plate 150 is created on the other side of the secondary beam web 121 of the secondary beam 120 .

[0088] Therefore, by changing the node variable C, the stiffening plate 150 can be created on one side of the secondary beam 120, which is convenient for operation.
