[0043] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0045] In a first aspect, an embodiment of the present application provides a concrete box girder design drawing method.

[0046] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the concrete box girder design drawing method of this application. Figure 1 As shown in the figure, the concrete box girder design drawing method includes:

[0047] Step S10: Receive the first design parameter, the second design parameter and the predefined target structural form input by the user, wherein the first design parameter includes the bridge length, standard width, span and angle, and the second design parameter includes the minimum steel bar arrangement spacing, the number of main bar layers, the prestressed arrangement spacing and the number of prestressed arrangement layers.

[0048] For example, in an embodiment of the present application, the predefined target structural form can be determined according to the target user's needs, which is not limited here; the first design parameters (i.e., structural design parameters) include bridge length, standard width, span and angle, etc. These parameters directly affect the structural layout and bearing capacity of the concrete box girder; for example, the bridge length and span determine the support point arrangement of the concrete box girder and the overall stability of its structure, the standard width determines the traffic capacity of the concrete box girder, and the angle may affect the stress state and design complexity of the concrete box girder; the second design parameters include the minimum steel bar arrangement spacing, the number of main bar layers, the prestressed arrangement spacing and the number of prestressed arrangement layers, etc. These parameters are mainly related to the steel bar and prestressed design of the concrete box girder, and determine the bearing capacity, bending resistance and durability of the concrete box girder; among them, the minimum steel bar arrangement spacing affects the configuration density of the steel bar and the pouring effect of the concrete, the number of main bar layers and the number of prestressed arrangement layers affect the mechanical properties and durability of the concrete box girder, and the prestressed arrangement spacing determines the arrangement density of the prestressed bars. Specifically, during the design process, the system first receives the first design parameter and the second design parameter input by the user, and performs analysis and calculation in combination with the predefined target structural form, and then draws the concrete box girder drawings based on the results of the analysis and calculation, thereby achieving the performance requirements and safety standards of the concrete box girder, while also ensuring the feasibility and economy of the construction.

[0049] Step S20: Calling a preset concrete box girder model and determining first and second drawing parameters based on the first and second design parameters, respectively. The first drawing parameters are drawing parameters corresponding to the target box girder cross-section, elevation, and planar structure of the target concrete box girder. The second drawing parameters are drawing parameters corresponding to the target reinforcement and prestressing arrangement of the target concrete box girder.

[0050] Exemplarily, in an embodiment of the present application, the first drawing parameter (i.e., the structural drawing parameter) is a drawing parameter corresponding to the target box girder cross-sectional structure, elevation structure, and plane structure in the target concrete box girder, and the second drawing parameter is a drawing parameter corresponding to the target steel bar and target prestressed arrangement form in the target concrete box girder, wherein the target box girder cross-sectional structure determines the cross-sectional geometry and force distribution of the beam, the elevation structure determines the longitudinal size and arrangement of the beam, the plane structure determines the transverse size and reinforcement arrangement of the beam, the target steel bar determines the force distribution of the beam, and the target prestressed arrangement form affects the bending resistance of the beam. The above three parameters are the core elements of the drawing of concrete box girder drawings. The reasonable design and precise drawing of these parameters ensure the safety, stability, and economy of the concrete box girder structure.

[0051] Specifically, in order to construct the concrete box girder model, refer to Figure 2As shown, first, a detailed concrete box girder database can be determined according to the design specifications and design drawings of concrete box girders. The database contains key design parameters such as geometric parameters (span, beam height, top and bottom plate thickness, web spacing), material parameters (concrete strength grade, steel yield strength, prestressed steel strand specifications), load parameters (standard value of dead load, live load grade, temperature gradient), structural parameters (prestressed tendon curve equation) and boundary conditions (support constraint type, seismic fortification intensity). These parameters can be refined and sorted according to national design specifications and standards and combined with the actual needs of specific projects; then, programming can be used to calculate the key design parameters. The design rules of concrete box girders are developed using languages (such as C++ and Python) to form a complete constraint network from mechanical calculation to structural design. The design rules include the design rules of concrete box girder structure, reinforcement and prestressing. These design rules specifically include code mandatory rules, crack width limits, structural experience rules and parameter association rules. The design rules and design parameters are then imported into a large language model for joint training to obtain trained data. The trained data is then processed by a concrete box girder design algorithm to obtain the concrete box girder cross-section form, reinforcement and prestressing design layout.

[0052] It should be noted that the concrete box girder model uses the attention mechanism to analyze the nonlinear mapping relationship between the design parameters and the drawing parameters, and establishes an end-to-end mapping function f(X)=Y from the input parameter set to the output parameter set, where the input X is the design parameter and the output Y includes the first drawing parameter and the second drawing parameter. Figure 2 As shown, when drawing a concrete box girder, the first design parameter and the second design parameter (i.e., the structural design parameter) are input into the concrete box girder model to obtain the drawing parameters corresponding to the concrete box girder (i.e., the first drawing parameter and the second drawing parameter).

[0053] It is understood that through deep learning of design parameters and design rules, the concrete box girder model can automatically identify the design rules and feasibility during the design process and generate standard-compliant drawing data based on the input design parameters. Specifically, the concrete box girder model can automatically calculate and output the first drawing parameter and the second drawing parameter, thereby realizing the automation and intelligent design of the concrete box girder. This application uses a large language model to fully understand the design parameters and design rules corresponding to the concrete box girder, and can convert the input design parameters into specific drawing parameters, thereby improving the efficiency and accuracy of the concrete box girder drawing.

[0054] Step S30: Draw a target drawing corresponding to the target concrete box girder based on the target structural form, the first drawing parameter, and the second drawing parameter.

[0055] For example, in an embodiment of the present application, the target structural form serves as the overall framework of the concrete box girder, which specifies the height type and width type of the concrete box girder; the target structural form is then combined with the first drawing parameter and the second drawing parameter, and a preset algorithm is used to automatically generate a target drawing corresponding to the target concrete box girder; the above process ensures a seamless connection from the structural design concept to the actual construction drawings, fully reflecting the technical advantages of intelligent design and automated drawing.

[0056] The present application receives first design parameters including bridge length, standard width, span and angle input by the user, second design parameters including minimum reinforcement spacing, number of main reinforcement layers, prestressing spacing and number of prestressing layers, and a predefined target structural form; calls a preset concrete box girder model and determines first drawing parameters corresponding to the target box girder section, elevation and plane structure in the target concrete box girder based on the first design parameters and the second design parameters, and second drawing parameters corresponding to the target reinforcement and target prestressing arrangement form in the target concrete box girder. The designer does not need to manually perform complex geometric calculations, and the system automatically generates the corresponding drawing parameters, which reduces the possibility of manual input errors and improves the accuracy of drawing drawing; draws the target drawing corresponding to the target concrete box girder based on the target structural form, the first drawing parameters and the second drawing parameters. By calling the concrete box girder model, the designer only needs to input the design parameters, and the system can automatically generate the corresponding drawing content, which greatly saves drawing time and improves the efficiency of drawing drawing.

[0057] Furthermore, in one embodiment, the first drawing parameters include section chamfer, web thickness, top plate thickness, and bottom plate thickness; and the second drawing parameters include steel bar size, stress arrangement spacing, top plate prestress, and bottom plate prestress.

[0058] For example, in the embodiment of the present application, the first drawing parameters include section chamfer, web thickness, top plate thickness and bottom plate thickness. These parameters play a key role in defining the shape and structural strength of the beam in the design of concrete box beams. Among them, the section chamfer helps to reduce stress concentration and ensure the stability of the structure by optimizing the corner shape of the beam. The web thickness, top plate thickness and bottom plate thickness directly affect the bearing capacity and bending and shear strength of the beam. The second drawing parameters include steel bar size, stress arrangement spacing, top plate prestress and bottom plate prestress. These parameters further refine the mechanical properties inside the beam. Through the reasonable configuration of steel bar size and stress arrangement spacing, the tensile and shear resistance; at the same time, the prestressed design of the top and bottom plates optimizes the force distribution of the structure and improves the crack resistance and durability of the box girder; it is understandable that the first drawing parameter and the second drawing parameter are interdependent, the former determines the geometric shape and strength basis of the beam, while the latter refines the distribution and optimization of the internal mechanics of the structure; the two work together to ensure that detailed drawings that meet design requirements can be accurately generated through the automated drawing process. The automated system can automatically adjust and optimize the design based on these parameters, reduce human errors, improve drawing efficiency, and ensure the high reliability of the drawings in terms of accuracy and consistency, thereby providing accurate technical support for subsequent construction and improving the quality control of overall design and construction.

[0059] Furthermore, in one embodiment, referring to Figure 3 As shown, calling a preset concrete box girder model and determining a first drawing parameter and a second drawing parameter based on the first design parameter and the second design parameter respectively include:

[0060] Step S201: inputting the first design parameter and the second design parameter into a preset concrete box girder model to generate the recommended cross-section, elevation, and plane configuration corresponding to the first design parameter and the recommended reinforcement and prestressing arrangement corresponding to the second design parameter;

[0061] Step S202: using the recommended section, elevation, and plane structure as target section, elevation, and plane structure in a target concrete box girder, and determining first drawing parameters based on the recommended section, elevation, and plane structure;

[0062] Step S203: Using the recommended steel bar and recommended prestressing arrangement as the target steel bar and target prestressing arrangement in the target concrete box girder, so as to determine a second drawing parameter based on the recommended steel bar and recommended prestressing arrangement.

[0063] Exemplarily, in an embodiment of the present application, after the first design parameter is input into a preset concrete box girder model, the model can generate recommended sections, elevations, and plane structures corresponding to the first design parameters based on the first design parameters, and use the recommended sections, elevations, and plane structures as the target sections, elevations, and plane structures in the target concrete box girder. Through the target sections, elevations, and plane structures, the system can further identify the first drawing parameters that match them, including section chamfers, web thickness, top plate thickness, and bottom plate thickness, etc., to ensure that the sections, elevations, and planes comply with the design specifications on the basis of meeting the strength and stability requirements.

[0064] It should be noted that after the second design parameters are input into the preset concrete box girder model, the model generates the recommended reinforcement and prestressing arrangements corresponding to the second design parameters. The recommended reinforcement and prestressing arrangements are then used as the target reinforcement and prestressing arrangements, and the system automatically identifies the corresponding second drawing parameters based on these targets. This process, through automated design optimization, ensures that each drawing parameter can be accurately determined, ensuring that the drawing parameters fully and accurately reflect the mechanical properties and construction requirements of the structure, improving design efficiency and accuracy, and ultimately generating detailed drawings that meet structural safety and construction requirements.

[0065] Furthermore, in one embodiment, after the step of respectively generating the recommended cross-section, elevation, and plan configurations corresponding to the first design parameter and the recommended reinforcement and prestressing arrangement corresponding to the second design parameter, the method further includes:

[0066] determining whether first modification parameters corresponding to the recommended section, elevation, and plan configurations have been received;

[0067] If so, taking the first modification parameter as the first drawing parameter;

[0068] If not, the step of using the recommended section, elevation and plane configuration as the target section, elevation and plane configuration in the target concrete box girder is performed.

[0069] For example, in the embodiment of this application, refer to Figure 2As shown in FIG, after the drawing parameters are output, the user can modify the drawing parameters. That is, after generating the recommended section, elevation, and plane structure corresponding to the first design parameters, the system enters the judgment stage. First, it determines whether the first modification parameter corresponding to the recommended section, elevation, and plane structure has been received. If the modification parameter is received, it means that the user has modified the parameters corresponding to the recommended section, elevation, and plane structure. At this time, the system can use the first modification parameter as the first drawing parameter to further adjust the specific design of the box girder section, plane, and elevation according to the user's modification requirements. This modification parameter may involve cross-sectional dimensions, angles, thickness, etc., with the purpose of personalized optimization of the structure according to design requirements. If the modification parameter is not received, it means that the user has not modified the parameters corresponding to the recommended section, elevation, and plane structure. Then, the system can continue to execute the step of using the recommended section, elevation, and plane structure as the target section, elevation, and plane structure in the target concrete box girder. In this process, the recommended section, elevation, and plane structure have fully considered the mechanical properties and design specifications. Therefore, if the user has no additional modification requirements, the system can directly perform subsequent drawing drawing based on this recommended solution.

[0070] Furthermore, in one embodiment, after the step of respectively generating the recommended cross-section, elevation, and plan configurations corresponding to the first design parameter and the recommended reinforcement and prestressing arrangement corresponding to the second design parameter, the method further includes:

[0071] determining whether a second modification parameter corresponding to the recommended reinforcement and prestressing arrangement is received;

[0072] If so, taking the second modification parameter as the second drawing parameter;

[0073] If not, the step of using the recommended steel bar and recommended prestressing arrangement as the target steel bar and target prestressing arrangement in the target concrete box girder is performed.

[0074] Exemplarily, in an embodiment of the present application, after generating the recommended steel bars and recommended prestressed arrangement corresponding to the second design parameters, the system enters a judgment phase, first determining whether a second modification parameter corresponding to the recommended steel bars and recommended prestressed arrangement is received. If the modification parameter is received, it indicates that the user has modified the parameters corresponding to the recommended steel bars and recommended prestressed arrangement. At this time, the system can use the second modification parameter as a second drawing parameter to further adjust the specific design of the steel bars and prestressed arrangement according to the user's modification requirements. This modification parameter may involve aspects such as the diameter of the steel bars, the layout of the prestressed steel bars, and the number of steel bars, with the purpose of performing personalized optimization of the structure according to design requirements. If the modification parameter is not received, it indicates that the user has not modified the parameters corresponding to the recommended steel bars and recommended prestressed arrangement. The system can continue to execute the step of using the recommended steel bars and recommended prestressed arrangement as the target steel bars and target prestressed arrangement in the target concrete box girder. In this process, the recommended steel bars and recommended prestressed arrangement have fully considered the mechanical properties and design specifications. Therefore, if the user has no additional modification requirements, the system can directly perform subsequent drawing drawing based on this recommended solution.

[0075] Furthermore, in one embodiment, referring to Figure 4 As shown, the method of drawing a target drawing corresponding to the target concrete box girder based on the target structural form, the first drawing parameter and the second drawing parameter includes:

[0076] Step S301: drawing a two-dimensional drawing and a three-dimensional drawing of the concrete box girder based on the target structural form, the first drawing parameter, the second drawing parameter, and a preset drawing scale;

[0077] Step S302: Calculating target engineering quantities of the concrete box girder structure, steel bars, and prestressing forces based on the first drawing parameter and the second drawing parameter;

[0078] Step S303: Determine the concrete box girder DXF drawing and the concrete box girder PDF drawing based on the two-dimensional drawing, the three-dimensional drawing, and the target project quantity;

[0079] Step S304: Use the concrete box girder DXF drawing and the concrete box girder PDF drawing as target drawings corresponding to the target concrete box girder.

[0080] For example, in an embodiment of the present application, the target drawings corresponding to the target concrete box girder include concrete box girder DXF drawings and concrete box girder PDF drawings. The preset drawing scale can be determined according to actual needs and is not limited here; the two-dimensional drawings mainly show the plan and cross-section views of the concrete box girder, and the three-dimensional drawings are used to show the spatial structure of the box girder for easy intuitive understanding; the DXF drawings are used for compatibility with software such as CAD, while the PDF drawings are used as the final display and sharing format.

[0081] Specifically, the system draws a two-dimensional drawing and a three-dimensional drawing of the concrete box girder based on a preset drawing scale, a first drawing parameter, and a second drawing parameter by calling a preset intelligent drawing algorithm. After generating the two-dimensional drawing and the three-dimensional drawing, the system draws a two-dimensional drawing and a three-dimensional drawing by referring to the preset drawing scale, a first drawing parameter, and a second drawing parameter. Figure 5 As shown, the three-dimensional model of the concrete box girder can be drawn using the drawing parameters in the drawing parameter database, and then the preset three-dimensional modeling algorithm is called to calculate the structure, reinforcement and prestress of the concrete box girder based on the three-dimensional model, thereby determining the target engineering quantity of the concrete box girder structure, reinforcement and prestress; then the preset intelligent drawing algorithm is called and based on the two-dimensional drawings, three-dimensional drawings, and target engineering quantity, a full set of DXF drawings and PDF drawings of the concrete box girder (i.e., target drawings corresponding to the target concrete box girder) is generated, wherein the full set includes structural drawings, reinforcement drawings, prestress drawings and other drawings; the above process ensures the integrity and feasibility of the drawing of the target drawings, and provides detailed technical support for subsequent construction and production. It should be noted that the principles and methods of the preset intelligent drawing algorithm, the preset three-dimensional modeling algorithm, and the preset intelligent drawing algorithm are common knowledge in this field, and for the sake of brevity of description, they are not described here.

[0082] It should be noted that, referring to Figure 5 As shown, users can input basic structural design parameters (first design parameters and second design parameters) and basic structural form into the concrete box girder model system to generate recommended sections, elevation and plane structures, recommended reinforcement, and recommended prestressing arrangements. At the same time, users can also modify parameters in the interface or directly design and modify the recommended bridge type, recommended reinforcement, and recommended prestressing arrangements in the view window to confirm the final section, elevation and plane structures, reinforcement, and prestressing arrangements. Based on the final section, elevation and plane structures, reinforcement, and prestressing arrangements, the corresponding drawing parameters are determined and stored in the drawing parameter database. The corresponding drawing frame is selected according to the drawing content and scale determined by the user. Two-dimensional and three-dimensional drawings are drawn according to the drawing parameters in the drawing parameter database and the intelligent drawing algorithm. The three-dimensional modeling algorithm can calculate the engineering quantities of the concrete box girder structure, reinforcement, and prestressing. The intelligent drawing arrangement algorithm is then combined to realize intelligent drawing arrangement and sub-drawing to generate a complete set of concrete box girder DXF drawings and PDF drawing sets. The concrete box girder model can read project data and continuously iterate and learn concrete box girder design.

[0083] Furthermore, in one embodiment, the target structural form includes a structure of equal width and equal height, a structure of equal width and variable height, and a structure of variable width and equal height.

[0084] Exemplarily, in an embodiment of the present application, the target structural forms include three structural forms: equal width and equal height structure, equal width and variable height structure, and variable width and equal height structure. These three structural forms can be selected based on the functional requirements and space constraints of the target personnel; specifically, in the equal width and equal height structure, the target width and height remain consistent, ensuring that the concrete box girder structure evenly distributes the load in all directions, which is suitable for concrete box girders with high spatial symmetry requirements; in the equal width and variable height structure, the width remains constant, while the height changes according to functional requirements or external conditions, which is suitable for concrete box girders that need to adjust the height to adapt to different working conditions; and the variable width and equal height structure meets different load requirements or optimizes space utilization by changing the width while keeping the height unchanged, which is suitable for concrete box girders that need to cover a large area or expand space. The present application can ensure the best structural performance and space efficiency in different working environments by making reasonable choices among these structural forms.

[0085] In a second aspect, an embodiment of the present application also provides a concrete box girder design drawing system.
