Description

Technical Field

[0001] This invention relates to the field of high-support formwork construction technology, specifically to a BIM-based visualization-based method for monitoring the erection of disc-lock scaffolding. Background Technology

[0002] With the increasing number of large-span structure buildings, high-formwork technology is widely used in the construction industry. Scaffolding is required to support building formwork or erect construction platforms during building construction. To ensure the safety of scaffolding use, it needs to be inspected and approved. Currently, the main inspection method involves the chief supervising engineer and professional supervising engineers conducting on-site inspections of the high-formwork support system area with plans and drawings. This existing method is not only slow but also prone to errors due to the large area and scale of the work, potentially leading to missed inspections of certain parts or areas and causing safety accidents. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a BIM-based visualization monitoring method for monitoring the erection of scaffolding. This method allows for supervision and acceptance during the scaffolding erection process. For large-area, large-span, and high-height modular scaffolding, installation problems can be directly identified through BIM comparison on a computer, enabling targeted inspection and greatly reducing inspection time and improving inspection efficiency.

[0004] This invention is achieved through the following technical solution: a BIM-based visualization-based method for monitoring the erection of modular scaffolding, comprising the following steps:

[0005] During the scaffolding erection process

[0006] S1. Obtain the coordinate data of the actually erected and installed components through the positioning signal source module, and send the coordinate data of the components to the computer, summarize it in Excel, and generate an Excel table;

[0007] S2. Convert the coordinate data in the Excel sheet into Revit-recognizable coordinate data using Gaussian projection;

[0008] S3. Use Dynamo in Revit to identify coordinate data in an Excel sheet, and use the identified coordinate data to create a raster model;

[0009] S4. Enter the dimensional parameters of the actual erected and installed components in Dynamo in Revit. Based on the raster model and the dimensional parameters of the components, Revit generates the actual model of the erected and installed components.

[0010] S5. Open Revit, and in the NavisWorks plugin's selection tree function, open the actual model and the schematic model. In the "Compare" window, check the required options and click the "OK" button to compare the actual model and the schematic model, obtain the model matching results, and find the abnormal parts of the actual installation based on the model matching results.

[0011] S6. Based on the model matching results, the supervisors will conduct targeted on-site verification and inspection.

[0012] Furthermore: the components are various components used for erecting scaffolding, including uprights, horizontal bars, diagonal bars, top supports, and foot supports.

[0013] Further: The method for obtaining the coordinate data of the actually erected and installed components through the positioning signal source module in step S1 is as follows:

[0014] S11. A positioning signal source module is set at the middle position of the component. The positioning signal source module is used to obtain the coordinate data of the component at its position.

[0015] S12. Set unit intermediates at equal intervals according to the distance of the received coordinate data;

[0016] S13. The positioning signal source module sends coordinate data to the computer through unit component intermediary.

[0017] Furthermore: the positioning signal source module includes a module body, the module body is rectangular, and each of the four corners of the module body is provided with a bendable fixing strip, the module body is fixed to the component by the fixing strip.

[0018] Furthermore, the unit intermediate includes a signal receiving module, an information storage module, a wireless bridge module, and a data transmission and sending module. The signal receiving module is used to receive coordinate data, the information storage module is used to temporarily store coordinate data to prevent the coordinate data from being lost after power failure, and the wireless bridge module is used to send the coordinate data to the computer.

[0019] Further: In step S3, Revit's Dynamo tool is used to identify coordinate data in the Excel sheet. The method for creating a raster model using the identified coordinate data is as follows:

[0020] S31. Open Dynamo and import the coordinate data from the Excel sheet into Dynamo through the Excel.ReadFromFile node. There are three interfaces for importing coordinate values: File represents the Excel object, sheetName represents the name of the Excel sheet, and readAsStrings indicates whether to read the result as a string.

[0021] S32. The imported list is read row by row, and the result is transposed using the List.Transpose node;

[0022] The values ​​of the X, Y, and Z components in S33 correspond exactly to the three sublists in the list, so the coordinate values ​​are obtained by extracting the index items. Since the first index item in the sublist is the three letters "X", "Y", and "Z", the index items are extracted starting from 1 and continuing until the end of the sublist;

[0023] S34. Use the extracted X, Y, and Z components as the basis for creating points to create a dot matrix model.

[0024] Furthermore, the dimensional parameters in step S4 include wall thickness, inner radius, outer radius, length, etc.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] This invention installs positioning signal source modules at the midpoints of uprights, diagonal braces, and horizontal braces used in scaffolding erection. During scaffolding erection, these modules acquire coordinate data of the erected components. Revit is then used to convert this coordinate data and dimensional parameters into a BIM-based visual model. This model is compared with the proposed model to obtain a matching result, identifying any abnormalities in the installation. This allows for on-site acceptance of the erected components, enabling supervision and acceptance during the scaffolding erection process. For large-scale, high-span, and high-height modular scaffolding, BIM-based comparisons can directly identify installation problems, allowing for targeted inspections and monitoring of corresponding scaffolding installation nodes. This strengthens supervision and risk management of scaffolding erection, significantly reduces acceptance time, improves efficiency, reduces human error, enhances overall stability, and minimizes safety risks.

[0031] Reference Figures 1 to 3 This invention discloses a BIM-based visualization-based method for monitoring the erection of disc-lock scaffolding, comprising the following steps:

[0032] During the scaffolding erection process

[0033] S1. Obtain the coordinate data of the actually erected and installed components through the positioning signal source module, and send the coordinate data of the components to the computer, summarize it in Excel, and generate an Excel table.

[0034] Specifically, the components are the various components used to erect scaffolding, including uprights, horizontal bars, diagonal bars, top supports, and foot supports.

[0035] The positioning signal source module 2 includes a module body 3, which is rectangular. Each of the four corners of the module body 3 is provided with a bendable fixing strip 4, and the module body 3 is fixed to the component by the fixing strip 4.

[0036] The module body 3 is 60mm long, 40mm high, and 10mm wide. A mounting hole matching the module body 3 is opened in the middle of the component. The module body 3 is placed in the mounting hole and then secured with the fixing clip 4. During fixation, the fixing clip is bent and secured to the outer wall of the component. The module body 3 is installed on the component using the bendable fixing clip 4, making installation and disassembly convenient. The positioning signal source module 2 is reusable.

[0037] The method for obtaining the coordinate data of the actually erected and installed components through the positioning signal source module is as follows:

[0038] S11. A positioning signal source module is set at the middle position of the component. The positioning signal source module is used to obtain the coordinate data of the component at its position.

[0039] S12. Set the unit intermediates at equal intervals according to the distance of the received coordinate data.

[0040] Specifically, the unit components are positioned within the projection area of ​​the disc-lock scaffolding installation to ensure stable signal reception and transmission.

[0041] S13. The positioning signal source module sends coordinate data to the computer through unit component intermediary.

[0042] Specifically, the unit intermediate includes a signal receiving module, an information storage module, a wireless bridge module, and a data transmission and sending module. The signal receiving module is used to receive coordinate data, the information storage module is used to temporarily store coordinate data to prevent data loss after power failure, and the wireless bridge module is used to send coordinate data to a computer.

[0043] S2. Convert the coordinate data in the Excel sheet into Revit-recognizable coordinate data using Gaussian projection.

[0044] S3. Use Dynamo in Revit to identify coordinate data in an Excel sheet, and use the identified coordinate data to create a raster model.

[0045] Specifically, the method for using Dynamo in Revit to identify coordinate data in an Excel sheet and then creating a raster model using that identified coordinate data is as follows:

[0046] S31. Open Dynamo and import the coordinate data from the Excel sheet into Dynamo through the Excel.ReadFromFile node. There are three interfaces for importing coordinate values: File represents the Excel object, sheetName represents the name of the Excel sheet, and readAsStrings indicates whether to read the result as a string.

[0047] S32. The imported list is read row by row, and the result is transposed using the List.Transpose node.

[0048] The values ​​of the X, Y, and Z components in S33 correspond exactly to the three sublists in the list, so the coordinate values ​​are obtained by extracting the index items. Since the first index item in the sublist is the three letters "X", "Y", and "Z", the index items are extracted starting from 1 and continuing until the end of the sublist.

[0049] S34. Use the extracted X, Y, and Z components as the basis for creating points to create a dot matrix model.

[0050] S4. Enter the dimensional parameters of the actual erected and installed components in Dynamo in Revit. Based on the raster model and the dimensional parameters of the components, Revit generates the actual model of the erected and installed components.

[0051] Specifically, the dimensional parameters of the components include wall thickness, inner radius, outer radius, and length. The dimensions of the components used in erecting disc-lock scaffolding should refer to the construction industry standard "Safety Technical Standard for Socket-Type Disc-Lock Steel Pipe Scaffolding in Building Construction" JGJ / T 231-2021.

[0052] S5. Open Revit, and in the NavisWorks plugin's selection tree function, open the actual model and the schematic model. In the "Compare" window, check the required options and click the "OK" button to compare the actual model and the schematic model, obtain the model matching results, and find the abnormal parts of the actual installation based on the model matching results.

[0053] Specifically, in the "Comparison" window, select the necessary options, including "Geometric Shapes" in the "Find Differences in the following aspects" option. In the "Results" option, select all options. The supervisor will use the software to automatically calculate and obtain the actual spacing and step distance of the uprights, the installation position of the diagonal braces, and the spacing and step distance of the horizontal bars used for the actual installation of the disc-lock scaffolding. The spacing or step distance of the components should refer to the installation specifications of the "Safety Technical Standard for Socket-type Disc-lock Steel Pipe Scaffolding in Building Construction" JGJ / T 231-2021 to identify any abnormal parts in the actual installation.

[0054] The model matching results are obtained by setting different colors to represent different types of components, so as to display the abnormalities in the actual installation of various components. For example, red indicates abnormal upright spacing, that is, the upright spacing is greater than or less than the installation specification requirements of the "Safety Technical Standard for Socket-type Disc-lock Steel Pipe Scaffolding in Building Construction" JGJ / T 231-2021, which is judged as abnormal upright spacing; blue indicates abnormal diagonal brace installation position; yellow indicates abnormal horizontal bar step distance, that is, the horizontal bar step distance is greater than or less than the installation specification requirements of the "Safety Technical Standard for Socket-type Disc-lock Steel Pipe Scaffolding in Building Construction" JGJ / T 231-2021, which is judged as abnormal horizontal bar step distance.

[0055] S6. Based on the model matching results, the supervisors will conduct targeted on-site verification and inspection.

[0056] In summary, by installing positioning signal source modules at the midpoint of the uprights, diagonal braces, and horizontal braces used in scaffolding erection, the coordinate data of the erected components can be acquired during the scaffolding erection process. Revit is then used to convert this coordinate data and dimensional parameters into a BIM-visualized model. The actual model is then compared with the proposed model to obtain model matching results. Based on these results, any abnormalities in the actual installation can be identified. This allows for on-site acceptance of the erected components, enabling supervision and acceptance during the scaffolding erection process. For large-area, high-span, and high-height modular scaffolding, installation problems can be directly identified via BIM comparison on a computer, allowing for targeted inspection and significantly reducing acceptance time and improving efficiency.

All equivalent implementations or modifications that do not depart from the present invention should be included in the patent scope of this case.
