Description

Technical Field

[0002] The structural design of modern buildings takes into account both the practicality and aesthetics of buildings. Steel structures are gradually being used in various public buildings due to their powerful and unique modeling capabilities and highly assembled construction processes. The mass of buildings ranges from several thousand tons to hundreds of thousands of tons. The huge amount of steel used poses a huge challenge to processing and manufacturing. How to improve processing and manufacturing efficiency has become a hot topic in the industry. From hardware equipment upgrades to software application development, all are aimed at improving processing efficiency and accuracy. However, the functions of most software will have different focuses. So how to combine the functions of each software and use a set of feasible operating procedures to meet the efficient layout of large quantities of parts.

[0003] In the design stage, most steel structure buildings will consider structural materials, bar sections, structural forms, etc. in order to meet the rationality of the structure and the economy of investment. In this way, more than two types of materials will be used, and different bar sections will have more than a dozen plate thicknesses. At the same time, different structural forms will face parts of different shapes, and the number of parts of various shapes will also be different. After the Tekla in-depth design model is disassembled, tens of thousands or even hundreds of thousands of parts with different properties will be generated. How to efficiently distinguish materials with different properties, aggregate parts of the same material, the same plate thickness, and different shapes, and assign quantity attributes, use nesting software to identify attributes such as shape, material, plate thickness, quantity, and complete high-utilization nesting is a topic worth studying. Summary of the invention

[0004] In view of the deficiencies in the prior art, this application proposes a method for rapid layout of batch parts of steel structures based on the combined application of multiple software functions.

[0005] This application includes the following technical solutions: A method for quickly arranging batch parts of steel structures based on the combined application of multiple software functions comprises the following steps: Step 1: Use Tekla, CAD, Rhino, Grasshopper plug-in and ST plug-in to complete the construction of complex building structure models, and conduct in-depth design of nodes to ensure that the node design meets the design requirements and has a certain rationality; check the collision of each node and rod of the model, and eliminate the collision so that each node and rod do not interfere with each other. The model after collision elimination is used as the final processing model; Step 2: Install the ST plug-in in the Tekla software, and use the rod debonding function to debond each welded composite section profile. Except for the hot-rolled profiles, all parts are cut, punched and curved in the form of plates, so that the properties of all parts, including plate thickness, material and quantity, are accurate; the ST plug-in exports each part as a DXF file. In order to efficiently process the DXF files, use the CAD merging software to merge the DXF files in the same export folder into one file to facilitate subsequent CAD preprocessing.

[0006] Step 3: Use the DXF drawing export function of the ST plug-in to export the DXF file containing quantity information, export all parts to DXF format, and classify and count the parts according to different materials and plate thicknesses to form folders with different names for easy recognition by the nesting software; Step 4: The ST plug-in exports each part as a separate DXF file, and uses CAD merging software to merge the DXF files in the same export folder into one file for subsequent CAD preprocessing; preferably, each part is exported as a DXF file, and in order to efficiently process the DXF files, the DXF files in the same export folder are merged into one file using CAD merging software to facilitate subsequent CAD preprocessing. Preferably, the merged DXF file will contain all parts of the same material and plate thickness, and the DXF file is preprocessed using CAD software, the quantity marks of all parts are selected, and the quantity marks of all parts are set as the BOM layer.

[0007] Step 5: Use CAD software to pre-process the merged DXF file, mark the number of parts to be cut on each part drawing, and move all quantity marks to the part drawing range so that the nesting software can recognize the number of parts; or when exporting the DXF file, choose to mark the number inside the part drawing through the ST plug-in; Set the quantity mark of all parts to the BOM layer; Step 6: Import the pre-processed DXF file into ProNest software, set the specifications and material of the plate, select the part quantity layer as the BOM layer, and start nesting; the software adopts the optimal arrangement method according to the shapes of different parts; Step 7: After completing the layout, export the DXF file for subsequent cutting.

[0008] Preferably, the above-mentioned layout method adopts a combination of functional applications of multiple software, adopts different application modes, takes advantage of their strengths, makes up for their weaknesses, and uses them flexibly to develop a solution for specific needs.

[0009] Furthermore, in the above-mentioned method for rapid layout of batch parts of steel structures based on the combined application of multiple software functions, in step one, the in-depth design process adopts the comprehensive application of Tekla, CAD, Rhino, Grasshopper plug-ins and ST plug-ins to achieve accurate modeling of complex building structures and rationality verification of node design.

[0010] Furthermore, in the above-mentioned method for rapid layout of batch parts of steel structures based on the combined application of multiple software functions, in the step two, the rod plate removal function can accurately process each welded combined cross-section profile, so that the properties of the parts after plate removal are accurate, providing a reliable basis for subsequent cutting, blanking, hole opening and surface forming.

[0011] Preferably, the rod-disassembling function is used to disassemble the welded composite cross-section profiles. Except for the hot-rolled profiles, all parts will be cut, punched and curved in the form of plates, and all part properties are accurate, including plate thickness, material, quantity, etc.

[0012] Furthermore, in the above-mentioned method for rapid layout of batch parts of steel structures based on the combined application of multiple software functions, in step three, the exported DXF file contains the quantity information of the parts, and is classified and counted according to different materials and plate thicknesses to form folders with different names, which is convenient for efficient recognition and processing by subsequent layout software. Preferably, the selection of exporting DXF files containing quantity information, exporting all parts as DXF files, and the exported files will classify and count parts of different materials and plate thicknesses to form folders with different names, such as Q355B+20mm, Q420B+35mm, etc.

[0013] Furthermore, in the above-mentioned method for rapid nesting of batch parts of steel structures based on the combined application of multiple software functions, in step five, the DXF file is preprocessed using CAD software, and the part quantity mark is set as the BOM layer to ensure that the nesting software can accurately identify and process the part quantity information.

[0014] Furthermore, in the above-mentioned method for rapid nesting of batch parts of steel structures based on the combined application of multiple software functions, in step six, the ProNest software can adopt the optimal arrangement method according to the shape of the parts, improve the utilization rate of raw materials, and at the same time provide simulated cutting paths and manual nesting functions to meet different processing requirements.

[0015] The present application also discloses the application of the above-mentioned method for rapid arrangement of batch steel structure parts in the field of steel structure construction.

[0016] Compared with the prior art, this application has the following beneficial effects: After the technical solution of the present application was put into practical use in the project, it showed remarkable beneficial effects. It can efficiently and accurately distinguish and manage large quantities of parts, and carefully classify parts according to different attributes such as material and plate thickness. By aggregating parts of the same material and plate thickness but different shapes, and accurately assigning their quantity attributes, the subsequent processing process is more orderly. At the same time, the solution makes full use of the powerful functions of the nesting software, which can accurately identify key attributes such as the shape, material, plate thickness and quantity of parts, thereby achieving high-utilization nesting. This not only greatly improves the utilization rate of raw materials and reduces waste, but also greatly improves work efficiency, shortens processing cycles, and reduces production costs.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0019] In the description of this application, it should be understood that the terms "install", "export", "import", "merge", "move", "set", "select", "simulate", etc., which indicate the description of the solution process, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply specific operations of a certain software, and therefore cannot be understood as limitations on this application.

[0020] In the description of this application, it should be understood that the terms "Tekla", "CAD", "Rhino", "Grasshopper", "ST plug-in", "ProNest" and the like indicating software descriptions are only for the convenience of describing this application and the solution process description based on the above software applications, rather than indicating or implying a specific function, and therefore cannot be understood as a limitation on this application.

[0021] Example like Figure 1 A method for rapid layout of batch parts of steel structures based on the combined application of multiple software functions is shown, comprising the following steps: Step 1: Use Tekla, CAD, Rhino, Grasshopper plug-in, ST plug-in, etc. to complete the construction of complex building structure models, and conduct in-depth design of nodes. The node design meets the design requirements and has a certain rationality. Check the collision of each node and rod of the model, and eliminate each collision to ensure that each node and rod do not interfere with each other. After the collision is eliminated, it is used as the final processing model; Step 2: Install the ST plug-in in Tekla software, and use the bar disassembly function to disassemble the welded composite section profiles. Except for the hot-rolled profiles, all parts will be cut, opened and curved in the form of plates. All part properties are accurate, including plate thickness, material, quantity, etc. Step 3. Use the export DXF drawing function of the ST plug-in, select the export DXF file containing quantity information, and export all parts as DXF files. The exported files will classify and count the parts of different materials and plate thicknesses to form folders with different names, such as Q355B+20mm, Q420B+35mm, etc. This step distinguishes parts of different materials and plate thicknesses, and gives the part drawing quantity attributes to facilitate recognition by the nesting software; Step 4. The ST plug-in exports each part as a DXF file. In order to efficiently process the DXF files, the CAD merging software is used to merge the DXF files in the same export folder into one file to facilitate subsequent CAD preprocessing. Step 5. The merged DXF file will contain all parts of the same material and plate thickness. Use CAD software to pre-process the DXF file. Each part drawing will mark the number of parts that need to be cut. Move all quantity marks to the part drawing range, otherwise the nesting software cannot recognize the number of parts. Or when exporting the DXF file, choose to mark the quantity internally in the ST plug-in. You can also mark the material, number, etc., but it is best not to mark the number and material. Select the quantity mark of all parts and set the quantity mark of all parts to the BOM layer; Step 6. Import the pre-processed DXF file into ProNest software, set the specifications and material of the plate, select the part quantity layer as the BOM layer, and then start nesting. The software will take the best arrangement method according to the shapes of different parts to improve the utilization rate of raw materials, and can simulate the cutting path and perform manual nesting. Step 7. After completing the layout, export the DXF file for cutting.

[0022] The above are limited to several preferred implementations of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
