Description

Technical Field

[0001] The invention relates to the field of steel structure production, transportation and management, and in particular to a full-process digital management method for steel structure production and installation. Background Art

[0002] At present, most of the domestic steel structure sectors have short construction periods and are designed and constructed at the same time, which brings great difficulties to material procurement and construction period. Affected by this, how to quickly and accurately submit materials, shorten the procurement cycle, and improve material utilization is the most critical link to ensure construction period and save costs.

[0003] At present, the main ways to submit materials in China are: 1. Wait for detailed drawings to be developed before submitting materials; 2. Submit part of the main materials first according to the design drawings, and then fill in the gaps after the detailed drawings are in-depth.

[0004] Both of the above methods have certain defects: 1. When submitting materials, we wait for detailed drawings to be available step by step. It takes a long time from design drawings to detailed drawings, which cannot meet the needs of construction progress; 2. When you layout and pick up materials by yourself according to the design drawings, you can only prepare the main materials. Confusion often occurs during the preparation process, and only the person who picks up the materials knows where the materials are used. There are great limitations, and it is difficult to achieve information universality. It is impossible to prepare parts accurately according to the design drawings. The usual practice is to purchase materials randomly by tons, which ultimately fails to reduce the material loss rate and increases project costs. For example, when purchasing part plates after waiting for detailed drawings, the construction progress has been affected.

[0005] There are many objective factors that cause the above situation, such as: 1. The biggest feature of steel structure materials is that they have many specifications and types. At present, in the existing management work, after the arrival of materials, it is necessary to manually enter the arrival information, manually match the procurement information with the arrival information, and manually count the final arrival results of the materials. When the steel structure is large in size, highly skilled personnel are required to enter, count, analyze, and process the material information to ensure the matching of the raw materials and the smooth progress of the production work; 2. Although there are many types of nesting software for steel structure cutting and there are many options to choose from, most manufacturers currently use nesting software as a gift when purchasing a cutting machine. A small number of manufacturers download free software from the Internet or purchase software separately. When using it, one software is used throughout the entire process, and they do not pay attention to the advantages and disadvantages of each software and improve its use.

[0006] From a practical point of view, the biggest feature of steel structure is the large number of types and parts, and the strong compatibility of components during installation. Therefore, it is necessary to control and track whether each component and part is produced according to the construction site schedule and on-site needs during the production process. At present, each production plant produces in batches according to the issued detailed drawings or according to the regional schedule given by the project. The manufactured components are compared with the schedule, and are manually entered and matched one by one. The workload is large and the accuracy is low. In addition, it is impossible to systematically check whether the manufactured components are compatible with the installation. If the site feedbacks the missing parts information, the installation progress on site will be affected.

[0007] In the installation of steel structures, we often encounter the dilemma of incompatible components arriving at the site and being unable to install. With the increasing number of incompatible components arriving at the site and the limitations of the construction site, the construction site often has to transport components back and forth many times. We also often encounter situations where components in a certain area have arrived at the site, but are still missing, the number of missing components is unclear, and the usage location is unclear. As the number of components increases, the traditional method of printing drawings, pasting wall markings, and grid markings cannot fully reflect the information statistics of small components and many types, and the workload is large and the accuracy is low. All of these will affect the construction progress of the project and increase the cost. Summary of the invention

[0008] The purpose of the present invention is to overcome the above-mentioned defects and to provide a full-process digital management method for steel structure manufacturing and installation.

[0009] In order to achieve the above object, the present invention is achieved as follows: A full-process digital management method for steel structure production and installation, characterized in that it includes: Step 1: Digitalization and module management steps in modeling and detailed drawing; Step 2: Digital and modular management steps in the material collection and delivery stages of typesetting; Step 3: Digital and modular management steps in cutting and production; Step 4: Digital and modular management steps in the component delivery process; in, In the above steps, Tekla software is used to implement modeling and drawing work; modular VBA tables are produced in each link, including material arrival comparison table, steel structure parts layout statistics tracking table; production status statistics tracking table, steel structure components, parts production, and delivery statistics table; in the layout and cutting links, Tekla software, Tekla nesting software, and Actcut software are used together to achieve layout and cutting.

[0010] The above-mentioned full-process digital management method for steel structure production and installation, in step 1, specifically includes the following contents: Step 1.1, in the Tekla modeling phase, after receiving the design drawings, inform the detailed modeling personnel of the modeling sequence. The model BH welded steel is modeled and numbered separately according to the upper and lower flange plates and web plates; the parts and components of various finished steel and plate materials in the built model must be able to be screened and edited separately, and the size, quantity, material, and part number of each part must be consistent with the detailed detailed information. Figure 1 consistent and accurate; Step 1.2, when modeling subsystems and sub-areas, the part numbers and component numbers cannot have the same numbers in the preparation model, the completed model, and the detailed drawing; if there are undetermined or unclear parts in the design drawings, they will not be modeled for the time being, and will be improved after the design problems are solved; loose parts connected by bolts or welded on site need to be compiled with separate component and part numbers, and can be screened and filtered separately, and are not modeled and drawn with the associated main components as a whole; each component in the "component list" should have a corresponding coordinate position; the parts list exported during typesetting should have the corresponding coordinate position and ID number; the detailed drawing is the net weight of cut limbs and corners.

[0011] The above-mentioned full-process digital management method for steel structure production and installation is to set up the Tekla software in step 2, use the data module to make complex dynamic layout material collection and material delivery work, and realize simple and efficient management through the program; specifically including: Step 2.1, after receiving the stable Tekla model, filter out the order of layout according to the order of construction schedule. The order of layout material collection and unloading is: main material, part plate, main material and part plate mixed layout to improve material utilization; Step 2.2, set the CNC value in Tekla software: When entering the model for the first time, open Tools → Selection → Advanced Options → CNC, find XS_DSTV_NUMBER_OF_PARTS_BY_SELECTION, and set the value to FALSE; Step 2.3, open file → output → create NC file → add NC file in NC file setting, adjust the values ​​of "maximum size" and "maximum hole size" under "select standard for parts" to 10 times the original values, click "OK" to return, check "Create", select the filtered parts, click the "Selected Parts" button to export the NC program file, find the "NCFiles" folder in the saved model, and classify the NCs of the same thickness and material separately to facilitate subsequent typesetting and information tracking; Step 2.4, select the "Select Objects in Component" button, select the filtered parts, click the "Id_select_part_list.rpt" button with the plug-in designed in the "Report" to get the parts list, find the "Reports" folder in the saved model, and copy and organize the information in the table into the "Process Tracking Table" in the "Steel Structure Part Layout Statistics Tracking Table" to prepare for the subsequent modular VBA program operation of the layout design; Step 2.5, take a screenshot of the layout area and save it to facilitate subsequent information review; Step 2.6, check the plate length in the parts list, if there are parts that exceed the purchase length or are irregular, mark these part numbers, find the corresponding NC, open it with Notepad to edit, modify it, and save it as a suffix number of -1 or -2; Step 2.7, use Tekla nesting software to layout and compile material procurement plan based on layout information. Each material procurement plan is summarized into "Plate Plan, Arrival Comparison" and "Profile Plan, Arrival Comparison" tables in "Material Arrival Comparison Table (Steel Plate, Profile)" according to plate and profile, to prepare for the operation of modular VBA program designed for subsequent material management; Step 2.8, export the parts list of the proposed planned area from the adjusted model ready for detailed drawing, and summarize it in the "Layout Statistics Tracking Table" in the "Steel Structure Part Layout Statistics Tracking Table"), run the designed modular VBA code program, check the running results, and find out the problems according to the "Interpretation" information, and then re-submit or reduce the material plan; Step 2.9, after the materials arrive at each manufacturing plant, verify the actual arrival information of the materials, and enter the materials with the measured dimensions into the "Plate Arrival Summary" and "Profile Arrival Summary" tables in the "Material Arrival Comparison Table (Steel Plate, Profile)" according to the profile and plate. After the entry is completed, run the designed modular VBA code program, check the running results, and modify and summarize the desired information according to the content in the "Interpretation" column; Step 2.10: According to the information in the construction schedule and the "Material Arrival Comparison Table (Steel Plates, Profiles)", check whether the material arrival status is consistent with the construction schedule. If it is inconsistent, feedback information such as material shortage and handle material problems.

[0012] In the implementation of step 3 of the above-mentioned full-process digital management method for steel structure fabrication and installation, in the routine typesetting work, the advantages of Tekla software, Tekla typesetting software, and Actcut typesetting software are found, and the best combination is used to simplify and improve the typesetting and cutting work; the data module is used to make the complex dynamic typesetting and cutting, and the production statistics work can be managed simply and efficiently through the program, which is more in line with the needs of the construction site; specifically, it includes: Step 3.1: The layout, cutting and cutting procedures of parts of each manufacturing plant shall be completed by the project department and agreed in the contract to ensure that the production sequence is carried out in accordance with the on-site construction progress, provide the prerequisite for orderly construction on site, and also reduce the workload of the layout personnel of each manufacturing plant; Step 3.2, export the NC program and parts list again from the Tekla model with stable part numbers, compare the actual length and width of the material with the corresponding layout drawing, modify the NC program for layout and adjustment again for inconsistent sizes, and continue to use the material layout drawing for materials with consistent length and width. Each time you layout according to the actual size, record the remaining material, defect elimination, and usage location information in the "Plate Arrival Summary" in the "Material Arrival Comparison Table (Steel Plate, Profile)". When layouting materials of the same thickness and material again, give priority to using the remaining material to improve material utilization and reduce the backlog of remaining materials; Step 3.3, open the layout drawing with CAD, keep only the layout drawing, delete all the frame information and ruler information and save each drawing separately. According to the characteristics of the "plotter" in Actcut software that can recognize the ".DXF" and ".DWG" formats and the "path finder" that can recognize the cutting gap, the cutting program is formed after combined application; Step 3.4: After completing the information in the folder, send it to the manufacturer and explain the precautions, and start the production work of cutting and blanking the steel structure; Step 3.5, after each detailed drawing is produced, the information in the columns from "Manufacturing Plant" to "Total Area" in the "Component List" and "Component Parts List" shall be completed according to the requirements of the "Manufacturing and Delivery Statistics Table". The update and completion of the "Manufacturing and Delivery Statistics Table" will provide important information support for the progress of component manufacturing, delivery status, and on-site component cleaning; Step 3.6: When the steel structure production enters the riveting and welding stage, the production plant is required to report and check the components that have been riveted and welded and the components that have been painted every day, and enter the information into the "Production Status Statistics Table" in the "Steel Structure Components, Parts Production (Riveting, Painting), and Delivery Statistics Table"; Step 3.7, run the designed riveting, welding and painting modular VBA code program, check the running results, and according to the content in the "Explanation" column, you can clearly understand the steel structure production status, whether it is produced according to the construction progress requirements, whether there are any omissions or production errors, etc., providing important information for the on-site supporting installation progress.

[0013] In the above-mentioned full-process digital management method for steel structure fabrication and installation, in step 4, a data module is used to enable the supporting statistical work of component shipment to meet management requirements simply and efficiently through the program; specifically, it includes: Step 4.1. According to the needs of the construction site schedule, when components and parts are shipped and loaded, the on-site personnel shall supervise the accuracy of the shipped components, part numbers, and quantity records, and fill in the delivery order according to the component and part numbers of the detailed drawing. If the component, part name, and cross-sectional specifications are not filled in in a standardized manner, the program cannot recognize them when running, so the content of the delivery order must be filled in in a standardized manner; Step 4.2. Add the columns of "Number of components and parts in the delivery vehicle (pieces)", "Number not yet arrived (pieces)", and "Weight of the drawing of the components that have arrived (t)" based on step 4.1; Step 4.3: After the components and parts are loaded, the information of one or more delivery notes is summarized, and then the designed modular VBA code program is run to check the running results. According to the content in the "Explanation" column, the problematic components are verified and processed. After the processing is completed, the on-site personnel will notify the vehicle transporting the components to start, and at the same time inform the construction site of the information; Step 4.4: The construction site will collect the delivery notes from each manufacturer at a fixed period and run the modular VBA code program. The information will be notified to the person in charge of the on-site installation to provide information support for the installation.

[0014] The digital management method proposed in the present invention improves the speed and accuracy of raw material plan submission, improves the speed and accuracy of statistical analysis of raw material arrival, and improves the utilization rate of raw materials through various modular digital technology management links. It accurately tracks component manufacturing information and component delivery supporting information, so that components arrive at the site in an orderly manner according to the site schedule, reduces the amount of components transported to the construction site, improves installation efficiency, and ultimately shortens the construction period and saves costs.

[0040] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection requested by the present application.

[0041] A full-process digital management method for steel structure production and installation, including Step 1: Modeling and detailed drawing requirements 1. Tekla modeling requirements will provide conditions for innovation management. After receiving the design drawings (electronic version, blueprint), inform the detailed modeling personnel of the modeling sequence. The model BH welded steel is modeled and numbered separately according to the upper and lower flange plates and web plates. All parts and components of various finished steel and plate materials in the built model can be selected and edited separately, and the size, quantity, material, and part number of each part are consistent with the detailed detailed modeling. Figure 1 The parts and components of the sub-system and sub-area modeling must be consistent and accurate. When modeling sub-systems and sub-areas, the part numbers and component numbers in the stock model, the model after the detailed model is completed, and the detailed detailed drawing cannot have the same number. If there are undetermined or unclear parts in the blueprint or electronic drawing, they will not be modeled for the time being, and will be improved after the design problems are solved. The loose parts connected by bolts or welded on site need to be compiled with separate component and part numbers (with "X" or "S" in the component and part numbers, such as 1X18, 2S6, etc.), and can be screened and filtered separately, and are not modeled and drawn with the main components connected to them. Each component in the "component list" should have the corresponding coordinate (X, Y) position. The parts list exported during typesetting should have the corresponding coordinate (X, Y) position and ID number. The detailed drawing is the net weight of the cut limbs and corners (the weight of the eyelet is not deducted).

[0042] Step 2: Modular management of layout and material delivery Set up Tekla software and use data modules to enable complex dynamic layout material collection and delivery, and achieve simple and efficient management through the program.

[0043] 1. After receiving the stable Tekla model, filter out the order of layout according to the order of the construction schedule. The order of layout material collection and cutting is: main material, part plate, main material and part plate mixed layout to improve the utilization rate of materials; 2. Set the CNC value in Tekla software: When you first enter the model, open Tools → Selection → Advanced Options → CNC, find XS_DSTV_NUMBER_OF_PARTS_BY_SELECTION, and set the value to FALSE. If you do not set the number of parts and the parts list during layout, the number of parts will be missing; 3. Open File → Output → Create NC File → Add NC File in NC File Settings, adjust the values ​​of "Maximum Size" and "Maximum Hole Size" under "Select Standard for Parts" to 10 times the original values ​​(if you do not set the values ​​in the model that are larger than the default values, the NC program cannot be generated, resulting in missing parts), click "OK" to return, check "Create", select the filtered parts, click the "Selected Parts" button to generate the NC program file, find the "NCFiles" folder in the saved model, and classify the NC files of the same thickness and material separately to facilitate subsequent typesetting and information tracking; 4. Select the "Select Objects in Component" button, select the filtered parts, and click the "Id_select_part_list.rpt" button with the plug-in designed in the "Report" to display the parts list. Find the "Reports" folder in the saved model, and copy and organize the information in the table into the "Process Tracking Table" in the "Steel Structure Part Layout Statistics Tracking Table" (see Figure 1 ), to prepare for the running of the modular VBA program for subsequent typesetting design; 5. Save the screenshot of the layout area to facilitate subsequent information review; merge the files with serial numbers 3 and 4 and the screenshot into one folder (see Fig. 22 ); 6. Check the plate length in the parts list. If there are parts that exceed the purchase length or are irregular (such as arc plates), mark these parts numbers and find the corresponding NC. Open them with Notepad to edit and save them with suffix numbers of -1 or -2 (to ensure that the modified program is consistent with the original program after splicing, see Figure 2 ); 7. Use Tekla nesting software to layout (see Fig.24 ), and compile the material procurement plan based on the layout information. Each material procurement plan is summarized into the "Plate Plan, Arrival Comparison" and "Profile Plan, Arrival Comparison" tables in the "Material Arrival Comparison Table (Steel Plate, Profile)" according to the plate and profile. (See Figure 2 , Figure 3 ), to prepare for the operation of the modular VBA program designed for subsequent material management; 8. Export the parts list of the proposed planned area from the adjusted model ready for detailed drawing, and summarize it in the "Layout Statistics Tracking Table" in the "Steel Structure Parts Layout Statistics Tracking Table" (see Figure 4), run the designed modular VBA code program, and check the running results (see Figure 5 , Figure 6 ), according to the "Interpretation" information, check for deficiencies and fill in the gaps, find out the problems, and resubmit or reduce the material plan according to the contents of No. 4, 5, 6, and 7; 9. After the materials arrive at each manufacturing plant, verify the actual arrival information of the materials, and enter the materials with the actual measured dimensions into the "Plate Arrival Summary" and "Profile Arrival Summary" tables in the "Material Arrival Comparison Table (Steel Plate, Profile)" according to the profile and plate respectively (see Figure 7 , Figure 8 ), after entering, run the designed modular VBA code program and check the running results (see Fig. 9 , Fig.10 , Fig.11 , Fig.12 ), modify and summarize the desired information according to the content in the "Definition" column.

[0044] 10. According to the information in the construction schedule and the "Material Arrival Comparison Table (Steel Plates, Profiles)", check whether the material arrival situation is consistent with the construction schedule. If it is inconsistent, feedback information such as material shortage and handle material problems.

[0045] Step 3: Cutting and making modular management In routine typesetting work, find out the respective advantages of Tekla software, Tekla typesetting software, and Actcut typesetting software, select the best ones and use them together to simplify and improve the efficiency of typesetting and cutting work; use data modules to make complex dynamic typesetting, cutting, and production statistics work simple and efficient through programs, which better meets the needs of the construction site.

[0046] 1. The layout, cutting and cutting procedures of parts of each manufacturing plant shall be completed by the project department and agreed in the contract to ensure that the production sequence is carried out in accordance with the on-site construction progress, provide the prerequisite for orderly construction on site, and also reduce the workload of the layout personnel of each manufacturing plant; 2. Export the NC program and parts list again from the Tekla model with stable part numbers, and Fig.24 Compare the layout drawings, modify the NC program for layout and adjustment again for inconsistent sizes, and continue to use the material layout drawing for materials with the same length and width. Each time the layout is made according to the actual size, the remaining material, defect elimination, and usage position information are recorded in the "Sheet Arrival Summary" in the "Material Arrival Comparison Table (Steel Plate, Profile)". When layouting materials of the same thickness and material again, the remaining material is used first to improve material utilization and reduce the backlog of remaining materials; 3. Open the layout drawing with CAD, keep only the layout drawing, delete all the frame information and ruler information, and save each drawing separately. According to the characteristics of the "plotter" in Actcut software that can recognize ".DXF" and ".DWG" formats and the "path finder" that can recognize the cutting gap, follow Fig.25 This method does not rely on detailed drawings to produce cutting procedures, which greatly reduces the workload of typesetting and improves typesetting efficiency; 4. Improvement Fig. 22 After the information in the folder is sent to the manufacturer and the precautions are explained, the steel structure cutting and blanking work begins; 5. After each detailed drawing is produced, the information in the columns from "Manufacturing Plant" to "Total Area" shall be completed according to the requirements of the "Manufacturing and Delivery Statistics Table" for the distributed parts in the "Component List" and "Component Parts List" (see Fig.13 ). The update and improvement of the "Production and Delivery Statistics Table" will provide important information support for component production progress, delivery status, and on-site component cleaning; 6. When the steel structure production enters the riveting and welding stage, the production plant is required to report and check the components that have been riveted and welded and the components that have been painted every day, and enter the information into the "Production Status Statistics Table" in the "Steel Structure Components, Parts Production (Riveting, Painting), and Delivery Statistics Table" (see Fig.14 ); 7. Run the designed riveting and painting modular VBA code program and check the running results (see Fig.15 , Fig.16 ), according to the content in the "Explanation" column, you can clearly understand the production status of the steel structure, whether it is produced according to the construction progress requirements, whether there are any omissions or production errors, etc., providing important information for the progress of on-site supporting installation.

[0047] Step 4: Modular management of component delivery The data module is used to make the supporting statistical work of component delivery meet the management requirements simply and efficiently through the program.

[0048] 1. According to the needs of the construction site schedule, when components and parts are shipped and loaded, the on-site personnel will supervise the accuracy of the shipped component, part number and quantity records, and Fig.13 Fill in the delivery note (see Fig.17 ), if the component, part name, and cross-section specifications are not filled in in a standardized manner, the program cannot recognize them when it is running, and the content of the delivery note must be filled in in a standardized manner; 2. In Fig.13 Add the columns of "Number of components and parts in the delivery vehicle (pieces)", "Number not yet arrived (pieces)", and "Weight of the drawing of the components that have arrived (t)" (see Fig.18 , in actual operation Fig.13 , Fig.18 To merge tables, different modular VBA codes); 3. After the components and parts are loaded, one or more delivery note information will be summarized in Fig.19 Then run the designed modular VBA code program and check the running results (see Fig. 20 , Fig.21 ), according to the content in the "Explanation" column, verify and handle the problematic components. After the processing is completed, the on-site personnel will notify the vehicle transporting the components to start. Fig. 20 , Fig.21 Inform the construction site of the information; 4. The construction site will collect the delivery orders of each factory at a fixed period. Fig.19 The modular VBA code program is run and the information is communicated to the person in charge of the on-site installation to provide information support for the installation.

[0049] It can be seen from the above implementation examples that this technical solution has the following characteristics and advantages compared with the prior art: 1. Requirements for modeling and detailed drawings: If no modeling requirements are put forward during modeling, the model built by the deepening unit will display a large amount of unnecessary data when filtering the model in the subsequent material collection stage (for example, in a certain steel structure project, the number of parts in the main steel structure production of 27,850 tons is 643,900). It takes a lot of time to delete, hide, and remove the board after the list and NC program are produced, and the accuracy cannot be guaranteed. For example, the traditional waiting for detailed drawings requires a lot of time from modeling to detailed drawings. Material collection according to detailed drawings requires manual classification of many parts and then layout and collection, which cannot guarantee the construction progress needs; if you layout and collect materials according to the design drawings, you can only prepare the main materials, and confusion often occurs during the preparation process. In addition, only the person who collects the materials knows the use location of the materials, which has great limitations and makes it difficult to achieve information universality; parts cannot be accurately prepared according to the design drawings. Materials are usually purchased randomly by tons, which ultimately cannot reduce the material loss rate and increase project costs. If you wait for detailed drawings before purchasing materials, it is already impossible to meet the construction progress. In the layout and cutting process, many parts need to be manually classified and then laid out, which is very easy to make mistakes and the progress is slow. In the construction and installation process, connecting plates and scattered small parts are often the key factors affecting the installation. If they are not required during modeling, it is difficult to find a place to use a large number of small parts, which seriously affects the construction progress. In the settlement process with the manufacturing plant, due to the large volume, one manufacturing plant cannot meet the construction period requirements, and multiple manufacturing plants are required. It is difficult to distinguish the production volume of each manufacturing plant from the components filtered out in the model. When settling according to the detailed drawings, it takes a lot of time to extract and filter data from the list and detailed drawings, which affects the settlement progress. It also takes a lot of time to extract and filter data from the list and detailed drawings when settling with the owner. After making requirements for modeling and detailed drawings in accordance with the planning of the construction site, division of tasks, actual conditions on site, and smooth and efficient management work, the specific area, component type, and component coordinate position can be quickly filtered and located when the materials are picked up and laid out. The BH steel does not need to be disassembled again, which greatly reduces the manual workload of finding the required information from a large amount of data and improves accuracy, also improves the material plan submission time and material utilization, and saves costs; in the material picking, unloading, production, and component delivery modules, through the designed modular VBA code program, the program is automatically matched, statistically analyzed, and calculated after running, which greatly reduces the workload of managers and the accuracy of information.

[0050] 2. In terms of modular management of typesetting material submission and incoming materials: At present, most of the projects are designed and constructed at the same time. How to set up the model in the dynamic construction, arrange the parts without omission and duplication, find out the deepening errors, and dynamically manage the layout plate are the problems that need to be solved before layout, so as to improve efficiency and reduce material loss. Figure 1 , Figure 4 , Figure 5 , Figure 6, dynamic problems encountered in material procurement can be quickly solved through the well-designed modular VBA code program. In traditional material procurement, there are only two methods: waiting for detailed drawings or waiting for the model of a certain area to be fully built before procuring materials, which takes more than 7 days; and arranging materials according to the design drawings, but only the main structure can be arranged and arranged, and the parts cannot be arranged and arranged. Materials can only be procured by tonnage, which cannot guarantee the utilization rate of materials and ultimately increases the project cost.

[0051] Furthermore, after the materials arrive at each manufacturing plant, it is necessary to count and summarize the specifications of each material in each vehicle and compare them with the material plan to see if there is over-delivery or shortage. Over-delivery will increase project costs, and under-delivery will affect the construction progress. The traditional material statistics comparison method is to add comparisons manually or use function comparisons, which is inefficient and labor-intensive. With the increase in the number of delivery vehicles, specifications, and tonnage, data statistics will become slower and slower, and the error rate will also increase. It is difficult to count the shortage or over-delivery at one time. Through the well-designed modular VBA code program, information can be accurately and quickly matched and counted. For example, if 1,000 tons of materials arrive, after the arrival information is entered, the running program can get the data within one minute. If it is compared manually or using functions, it will take at least 30 minutes.

[0052] 3. In terms of modular management of cutting and production: The focus of steel structure major is on the early stage of on-site planning, the focus of planning is on production, the focus of production is materials, the focus of materials is typesetting and cutting, and production serves on-site installation. Therefore, the management of material cutting is directly related to the construction progress and cost of the project. There are only two traditional practices: a small part of the typesetting and cutting is done by the project department (or Party A), and the use of typesetting software is a whole process of typesetting software. There are many typesetting software in China, but the disadvantage is that the typesetting efficiency is low. For example, in a certain iron-based new material quality improvement project, a total of 27,850 tons of steel structure were produced by 4 manufacturing plants. Regardless of the project or the manufacturing plant typesetting, typesetting requires 8 people to contact and work for 5 months, and there is currently no use of two sets of typesetting software in China to complete a full process of typesetting work; most of the typesetting and cutting are completed by the manufacturing plant. According to the characteristics of the manufacturing plant, if there are not too many Limitations, will first make heavy components, then make small components, the disadvantage is that it is impossible to accurately control material loss, cutting direction and component matching. When cutting materials, if the material is not cut according to the requirements of the previous procurement layout, the material loss will increase, and it is necessary to purchase materials again, the project cost and procurement time will be lost. The cutting direction (a production cycle takes about 15 days) and the matching of the components are not strictly produced according to the schedule. The finished components will not be able to be installed, and the construction site of the finished components will not have the installation conditions, which will directly affect the entire construction progress. In view of the above shortcomings, the cutting and layout work is all completed by the project department (or Party A). At the same time, the layout software at home and abroad is studied to find out the advantages and disadvantages of each software. The "grafting" method is adopted. A full-process layout work uses Tekla nesting software and Actcut software in combination, which greatly improves work efficiency. The traditional 8-person layout work now only requires 3 people to work for a total of 3 months, which improves the layout efficiency and material utilization rate, and also fully controls the production sequence and progress.

[0053] At the same time, the biggest feature of steel structure installation is that it requires strong matching of components. Construction sites often encounter situations where a small number of components in the area to be installed have not been made, resulting in a large number of components that cannot be installed. After the problem is found, production and delivery will have a great impact on the progress of on-site installation and increase project costs. The traditional method is to manually make tables or print drawings to mark and match them to the components made in a certain area. However, as the number of manufactured components increases, the matching work will become more and more cumbersome and the accuracy will also decrease. Each manufacturing plant needs dedicated personnel to maintain information statistics, which increases management costs. In response to such problems, the present invention Fig.13 , Fig.14 , Fig.15 , Fig.16 Through the well-designed modular VBA code program, it is possible to quickly and automatically match the components and parts in the planned installation area to see whether they have been riveted and welded, whether they have been painted, and whether the components are matched. For the unmatched components and parts, it is possible to request their production in a timely manner and track the information again.

[0054] 4. In terms of modular management of component delivery: The orderly and coordinated delivery of components and parts is the most direct factor affecting the progress and cost increase or decrease of the construction site. Traditional methods: large-scale delivery without considering the compatibility of components, finding a storage site for components and parts at the construction site, and then transporting them again during subsequent installation, which increases site inventory fees, machinery usage fees, and labor costs; manual record matching or printed drawing mark matching. This method is only used for a small number of components and parts or large components. For the delivery of a large number of components and parts, the information accuracy is low, and the operability and feasibility are poor. It has basically no use value to the construction site. In the end, the compatibility of the installation of components and parts has not been substantially solved, which directly increases the cost of the construction site and extends the construction period. In response to such problems, the present invention Fig.13 , Fig.14 , Fig.15 , Fig.16 Through the well-designed modular VBA code program, it is possible to quickly and automatically match whether the components in the installation area are matched, missing, or multiple, and solve the problems in a targeted manner, ensuring the matching and continuity of the on-site steel structure installation, ultimately improving installation efficiency and saving costs.
