Description

Technical Field

[0001] This invention relates to the field of construction technology for irregular steel structures, and specifically to a construction method and system for irregular steel structures based on BIM technology. Background Technology

[0002] Irregular steel structures, also known as spatial arbitrary steel structures or special-shaped steel, refer to steel structures composed of different and unconventional shapes. These structures form various shapes in space, not only possessing a strong sense of space and aesthetic appeal but also providing a novel visual experience. Due to the special nature of their structure, construction workers encounter various difficulties during the installation of irregular steel structures. These difficulties include construction challenges caused by the construction location, deformation caused by poor assembly quality due to unreasonable assembly sequence, and mismatch between the installation location and design parameters due to accumulated errors. It is necessary to communicate with the designers in real time to resolve these issues before proceeding to the next step of construction. This not only places extremely high demands on the designers' abilities but also requires a significant amount of time for readjustment, thus reducing construction efficiency. Summary of the Invention

[0003] This invention provides a construction method and system for irregular steel structures based on BIM technology, which solves the problem of reduced construction efficiency caused by the inability to obtain timely feedback from designers when abnormal situations occur during the construction of irregular steel structures.

[0004] A construction method for irregular steel structures based on BIM technology includes the following steps:

[0005] Construct a BIM model of the irregular steel structure and set up a simulation environment to simulate the BIM model of the irregular steel structure to obtain the construction plan of the irregular steel structure;

[0006] During the construction process according to the construction plan, data is collected on the installation process of each component of the irregular steel structure, and the collected installation data is uploaded to the server.

[0007] Analyze the installation data to obtain the installation status of each component of the irregular steel structure;

[0008] Based on the obtained installation status, the position of the components is analyzed according to the BIM model of the irregular steel structure, and the installation of the components is guided to match the installation position of the components with the design parameters.

[0009] If any abnormal situation occurs during the installation process, the construction personnel will collect abnormal data through the client and upload it to the server;

[0010] After analyzing the abnormal data, a solution is provided and evaluated. If the evaluation is successful, the construction of the irregular steel structure is adjusted according to the solution. If the evaluation fails, other solutions are generated and evaluated again until the evaluation is successful.

[0011] Furthermore, the construction plan for irregular steel structures includes the construction process, materials, and connection methods.

[0012] Furthermore, during the construction process, optical measuring instruments are used to obtain the positional data of each component of the irregular steel structure during the installation process.

[0013] Furthermore, abnormal conditions include construction difficulties caused by the construction location, deformation caused by low assembly quality of steel structures due to unreasonable assembly sequence, and mismatch between installation location and design parameters caused by cumulative errors.

[0014] Furthermore, in the event of abnormal situations that cause construction difficulties due to the construction location, solutions should be provided according to the following steps:

[0015] The location of the anomaly was determined based on the abnormal data uploaded by the construction personnel through the client.

[0016] Analyze components in abnormal locations;

[0017] When construction difficulties can be resolved by adjusting the installation sequence, the adjusted installation sequence can be obtained through simulation.

[0018] When construction difficulties cannot be resolved by adjusting the installation sequence, a feasibility analysis of component decomposition is conducted. If the construction difficulties can be resolved by decomposing the components into blocks for installation, simulation is used to obtain the location and installation sequence of the component decomposition.

[0019] Furthermore, when abnormal deformation occurs due to low assembly quality of the steel structure caused by an unreasonable assembly sequence, the following steps provide a solution:

[0020] The location of the anomaly was determined based on the abnormal data uploaded by the construction personnel through the client.

[0021] The installation sequence at abnormal locations is simulated and calculated to obtain a new installation sequence.

[0022] Furthermore, in cases where cumulative errors cause a mismatch between the installation location and design parameters, the following steps provide a solution:

[0023] The location of the anomaly was determined based on the abnormal data uploaded by the construction personnel through the client.

[0024] The installation status of components in abnormal locations is analyzed, and the error is calculated. When the error is less than a first threshold, a first solution is given; when the error is less than a second threshold but greater than the first threshold, a second solution is given; and when the error is greater than the second threshold, a third solution is given.

[0025] Furthermore, the first solution does not change the original connection method, the second solution changes the original connection method and installation location, and the third solution changes the parameters of the current component and re-manufacturing the component.

[0026] Secondly, embodiments of the present invention provide a construction system for irregular steel structures based on BIM technology, comprising:

[0027] The installation process management module is suitable for collecting data during the installation process and guiding the installation process of components, so that the installation position of the components matches the design parameters;

[0028] The anomaly analysis module is suitable for analyzing abnormal conditions affecting component installation during the installation process and determining the type of anomaly.

[0029] The module is adjusted to output corresponding solutions based on the type of exception.

[0030] The structural evaluation module is suitable for evaluating solutions. If the evaluation passes, the construction of the irregular steel structure is adjusted according to the solution. If the evaluation fails, other solutions are generated and evaluated again until the evaluation passes.

[0031] The beneficial effects of the above-described technical solutions provided in the embodiments of the present invention include at least the following:

[0032] This invention collects data on the installation process of various components of an irregularly shaped steel structure, analyzes the position of the components based on the BIM model of the irregularly shaped steel structure, and guides the installation of the components to ensure that the installation position of the components matches the design parameters. When abnormal situations occur during the installation process, the construction personnel collect abnormal data through the client and upload it to the server for analysis of the abnormal situation and to provide solutions. At the same time, the solutions are evaluated, and if the evaluation is approved, the construction of the irregularly shaped steel structure is adjusted according to the solution. This not only provides timely feedback of adjustment information to the construction personnel, but also improves the feedback efficiency and construction efficiency of irregularly shaped steel structures without the need for designer intervention.

[0040] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0041] like Figure 1 As shown, this embodiment of the invention provides a construction method for irregular steel structures based on BIM technology, including the following steps:

[0042] S1. Construct a BIM model of the irregular steel structure and set up a simulation environment to simulate the BIM model of the irregular steel structure to obtain the construction plan of the irregular steel structure.

[0043] The steps for constructing a BIM model of an irregularly shaped steel structure are as follows:

[0044] S11a, obtain the design parameters of the irregular steel structure;

[0045] S12a: Import the acquired data into the modeling software to construct the initial 3D model;

[0046] S13 a, Perform model verification, check the model's accuracy and integrity, and export it to a general format after confirming that there are no errors;

[0047] S14 a, Import the previously exported model file into the BIM software, adjust and optimize the model layout to meet the actual engineering requirements.

[0048] S15 a, Perform various performance tests on the model to ensure that it meets the design requirements and design specifications.

[0049] S16 a. If the detection results do not meet the standards, the model needs to be modified and optimized until all indicators meet the requirements.

[0050] To obtain a construction plan for an irregularly shaped steel structure, a simulation environment is set up to simulate the BIM model of the irregular steel structure, following these steps:

[0051] S11b: Import the BIM model data of the irregular steel structure into the simulation software for preliminary model display and inspection.

[0052] S12b, Add simulation parameters: Set relevant parameters in the simulation software, such as ambient temperature, humidity, wind speed, and light intensity, to simulate real environmental conditions.

[0053] S13b, Run Simulation: Run simulation calculations according to requirements and obtain analysis results.

[0054] S14b, Analysis Results: View and analyze the simulation results to verify the effectiveness and feasibility of the design.

[0055] S15b, Optimized Design: Based on the simulation results, optimize the design, adjust the BIM model, and improve the design scheme.

[0056] S16b, Repeated Simulation: After optimizing the design, repeat the above steps multiple times until the design requirements and simulation objectives are met.

[0057] S17b, Export construction plan. The construction plan for irregular steel structures includes construction process, materials, and connection methods.

[0058] S2, during the construction process according to the construction plan, data is collected on the installation process of each component of the irregular steel structure, and the collected installation data is uploaded to server 5;

[0059] Specifically, during the construction process, optical measuring instruments are used to obtain the positional data of each component of the irregular steel structure during the installation process.

[0060] In one embodiment, the optical measuring instrument is a total station, used to obtain the position of the steel structure.

[0061] For example, during the installation process, the total station collects the coordinates of each component.

[0062] S3, analyze the installation data to obtain the installation status of each component of the irregular steel structure;

[0063] Specifically, server 5 analyzes the uploaded component coordinates to obtain the component's installation location information.

[0064] S4. Based on the obtained installation status, the position of the components is analyzed according to the BIM model of the irregular steel structure, and the installation of the components is guided to match the installation position of the components with the design parameters.

[0065] Specifically, during the installation process, server 5 monitors the position of the components in real time and provides guidance information to client 7 to ensure that the installation position matches the design parameters.

[0066] S5, if any abnormal situation occurs during the installation process, the construction personnel will collect abnormal data through the client 7 and upload it to the server 5;

[0067] Specifically, abnormal situations include construction difficulties caused by the construction location, deformation caused by low assembly quality of steel structures due to unreasonable assembly sequence, and mismatch between installation location and design parameters caused by cumulative errors.

[0068] In the first embodiment, when an abnormal situation arises that causes construction difficulties due to the construction location, a solution is provided according to the following steps:

[0069] S51a, Determine the location of the anomaly based on the abnormal data uploaded by the construction personnel through client 7;

[0070] Specifically, construction workers obtain image data of abnormal locations through client 7, such as a mobile phone, and upload it to server 5 through base station 6. Server 5 analyzes the images to determine the location of the abnormality.

[0071] S52a, Analyze components in abnormal locations;

[0072] Specifically, server 5 determines the range of the abnormal location based on the uploaded image data, marks the components involved, obtains a component list, and generates two solutions as shown in steps S53a to S54a, and performs a feasibility analysis.

[0073] S53a, when construction difficulties can be resolved by adjusting the installation sequence, the adjusted installation sequence can be obtained through simulation;

[0074] In one example, by analyzing the uploaded image data and simulating adjustments to the components involved, the abnormal situation of construction difficulties caused by the construction location can be resolved by adjusting the installation sequence, and the adjusted solution is output to the client 7.

[0075] S54a When the construction difficulties cannot be solved by adjusting the installation sequence, a feasibility analysis of component decomposition is performed. If the construction difficulties can be solved by decomposing the components into blocks for installation, the location and installation sequence of the component decomposition are obtained through simulation.

[0076] In one example, by analyzing the uploaded image data and performing simulation adjustments on the involved components, if a solution cannot be found to resolve the abnormal situation of construction difficulties caused by the construction location by adjusting the installation sequence, the components are decomposed for feasibility analysis, several solutions are generated, and simulations are performed to obtain a solution that resolves the construction difficulties by decomposing the components into blocks for installation. The adjusted solution is then output to the client 7.

[0077] In the second embodiment, when an abnormal situation of deformation occurs due to low assembly quality of the steel structure caused by an unreasonable assembly sequence, a solution is provided according to the following steps:

[0078] S51b, determine the location of the anomaly based on the abnormal data uploaded by the construction personnel through client 7;

[0079] Specifically, construction workers obtain image data of abnormal locations through client 7, such as a mobile phone, and upload it to server 5 through base station 6. Server 5 analyzes the images to determine the location of the abnormality.

[0080] S52b performs simulation calculations on the installation sequence at abnormal locations to obtain a new installation sequence.

[0081] The server 5 determines the range of the abnormal location based on the uploaded image data, marks the components involved, obtains a component list, re-simulates the installation order of the components on the component list, obtains a new installation order, and outputs it to the client 7.

[0082] In the third embodiment, when an abnormal situation arises where the installation position does not match the design parameters due to accumulated errors, a solution is provided according to the following steps:

[0083] S51c, determines the location of the anomaly based on the abnormal data uploaded by the construction personnel through client 7;

[0084] Specifically, construction workers obtain image data of abnormal locations through client 7, such as a mobile phone, and upload it to server 5 through base station 6. Server 5 analyzes the images to determine the location of the abnormality.

[0085] S52c analyzes the installation status of components in abnormal locations, calculates the error amount, and provides a first solution when the error amount is less than a first threshold, a second solution when the error amount is less than a second threshold but greater than the first threshold, and a third solution when the error amount is greater than the second threshold.

[0086] It should be noted that the first to third thresholds represent the error between the current installation position and the design position of the component. These thresholds need to be set according to the actual situation. The first solution does not change the original connection method, the second solution changes the original connection method and installation position, and the third solution changes the parameters of the current component and re-manufacturing the component.

[0087] In the first example, when the error is an operational error, the first solution is to use tools or equipment to precisely shift the component and correct the error.

[0088] In the second example, the error is an accumulated error. In this case, the error can be corrected by changing the connection method. The second solution is to re-simulate the position of the component and then use the new connection method for installation.

[0089] In the third example, the error is a cumulative error, and the error amount can no longer be corrected by changing the connection method. The third solution is to redesign the component, match and simulate it with the currently installed and uninstalled components to obtain new component parameters, and then remanufacture and install it.

[0090] It should be noted that the cumulative error includes factors such as the influence of welding on the component and temperature changes.

[0091] S6 analyzes abnormal data and provides solutions. It also evaluates the solutions. If the evaluation is successful, the construction of the irregular steel structure is adjusted according to the solution. If the evaluation fails, other solutions are generated and evaluated again until the evaluation is successful.

[0092] This invention also discloses a construction system for irregular steel structures based on BIM technology, such as... Figure 2 It includes: Installation process management module 1, anomaly analysis module 2, adjustment module 3 and structure evaluation module 4, which are set on server 7.

[0093] Installation process management module 1 is suitable for collecting data during the installation process and guiding the installation process of components to match the installation position of components with design parameters;

[0094] Anomaly analysis module 2 is suitable for analyzing abnormal conditions affecting component installation during the installation process and determining the type of anomaly;

[0095] Adjust module 3 to output corresponding solutions based on the type of exception;

[0096] The structural evaluation module 4 is suitable for evaluating solutions. If the evaluation is successful, the construction of the irregular steel structure is adjusted according to the solution. If the evaluation fails, other solutions are generated and evaluated again until the evaluation is successful.

[0097] This invention collects data on the installation process of various components of an irregular steel structure, analyzes the position of the components based on the BIM model of the irregular steel structure, and guides the installation of the components to ensure that the installation position of the components matches the design parameters. When abnormal situations occur during the installation process, the construction personnel collect abnormal data through the client 7 and upload it to the server 5 for analysis of the abnormal situation and to provide solutions. At the same time, the solutions are evaluated, and if the evaluation is approved, the construction of the irregular steel structure is adjusted according to the solution. This not only provides timely feedback of adjustment information to the construction personnel, but also improves the feedback efficiency and construction efficiency of irregular steel structures without the need for the involvement of designers.
