[0023] The embodiment of the present invention is also implemented through the following technical solutions.
[0024] In an embodiment of the present invention, a mold frame design system 500 is used to design the structure of the mold frame 100 of a super-high chimney according to the construction plan of the super-high chimney and adjust the structure according to the real-time construction status of the mold frame 100. The mold frame design system 500 includes a structure design module 501, a construction monitoring module 502, a data analysis module 503 and an early warning module 504. The structural design module 501 is used to design the structure of the turnover frame 100 according to the construction plan of the super-high chimney; The construction monitoring module 502 is used to monitor the construction status and structural status of the formwork frame 100 in real time, including structural damage, structural status, etc. The data analysis module 503 is used to analyze and process the monitored data and provide a real-time optimization solution. The data analysis module 503 includes an LSTM neural network prediction unit 5031, a multivariate statistical analysis unit 5032, and a construction solution feedback unit 5033; The LSTM neural network prediction unit 5031 uses the LSTM neural network to build a model, applies real-time data to the model, and predicts the state of the mold frame 100; The multivariate statistical analysis unit 5032 is used to analyze the sensitivity of the monitoring data to the safety status of the mold frame 100 and provide an explanation for the prediction results of the LSTM neural network prediction unit 5031; The construction plan feedback unit 5033 adjusts the construction plan of the mold frame 100 according to the predicted results and provides real-time feedback to the staff; The early warning module 504 is used to issue an early warning when the monitoring data exceeds the safety threshold, prompting the staff to make adjustments; The safety threshold is set based on the finite element simulation, and the warning level is dynamically divided according to the proportion of the predicted results deviating from the safety threshold: Level 1 warning (deviation 2%-5%): sound and light alarm; Level 2 warning (deviation 5%-8%): Automatically send adjustment instructions; Level 3 warning (deviation > 8%): triggers emergency shutdown.
[0025] In an embodiment of the present invention, the structural analysis and design module includes a structural analysis unit 5011, a BIM simulation unit 5012, and an output unit 5013; The structural analysis unit 5011 simulates the structural design of the mold frame 100 using finite element software; The BIM simulation unit 5012 uses BIM technology to perform a three-dimensional simulation based on the structural scheme of the mold frame 100, optimizes the structure of the mold frame 100, and obtains an optimized scheme. If the BIM modifies the structural parameters (such as the spacing between crossbars), it is necessary to retrain the LSTM to update the parameter data; The output unit 5013 outputs the optimized plan in the form of drawings for staff to review.
[0026] In an embodiment of the present invention, the data analysis module 503 uses the LSTM neural network prediction unit 5031 and the multivariate statistical analysis unit 5032 to process and analyze the construction data of the turnover frame 100 in the following detailed steps: Step a: pre-processing the data from the construction monitoring module 502, including missing value processing, outlier processing, data normalization, etc., using multivariate statistical analysis methods to analyze the correlation between features and construction status, and selecting features with large contribution values based on the correlation results; Step b: Design the structure of the LSTM neural network model, including the number of nodes and activation function of the input layer and output layer, train the model using historical data, adjust the model parameters, and verify the model using the validation set to obtain a trained model; Step b1: Determine the number of input layer nodes of the LSTM neural network based on the number of key monitoring indicators screened by the multivariate statistical analysis unit 5032. The number of hidden layers is adjusted based on the complexity of the construction data. When the number of monitoring parameters exceeds 8 categories, a hidden layer is added. When the number of monitoring parameters is less than 8 categories, the remaining nodes are input with historical means or environmental parameters (such as wind load). The number of output layer nodes is set based on the prediction target (including at least three categories: displacement, stress, and safety factor). During model training, the learning rate is dynamically adjusted based on the rate of decrease of the loss function. Training is automatically terminated when the accuracy of the validation set does not improve after three consecutive iterations. Step b2: determine the loss function of the model and use an optimizer to adjust the model parameters to reduce the value of the loss function to obtain an optimized model; Step b3: input the preprocessed training data into the model, and adjust the model parameters through multiple iterations until the model reaches the pre-set indicators to obtain the final model; Step c: Analyze the monitoring data using principal component analysis to reduce the data dimension, and establish a regression model between the monitoring data and the construction status to predict the safety status change of the turnover formwork frame 100, thus supplementing the prediction results of the LSTM. Step c1: Center and standardize the original data, calculate its covariance matrix based on the standardized data, perform eigenvalue decomposition on the covariance matrix to obtain eigenvalues and corresponding eigenvectors, select the principal component whose cumulative variance contribution reaches a predetermined threshold based on the size of the eigenvalue, project the original data onto the principal component, obtain the principal component score, and generate a new low-dimensional data representation; Step c2: Select an appropriate regression model, such as linear regression or multiple regression, based on data characteristics and requirements. Use appropriate methods, such as statistical tests and information criteria, to screen out independent variables that have a significant impact on the dependent variable. Use the selected independent and dependent variables to estimate model parameters, establish a quantitative relationship between the independent and dependent variables, perform statistical tests on the estimated model, such as F tests and t tests, to assess the significance of the model, and use the established regression model to make predictions, providing data support for construction plan adjustments and risk control. Step c3: Identify the safety status indicators and monitoring indicators to be analyzed. Select appropriate sensitivity analysis methods based on data characteristics and requirements, such as single-factor sensitivity analysis and multi-factor sensitivity analysis. Set a reasonable range of variation for each monitoring indicator. By changing the monitoring indicator, observe the degree of change in the safety indicator and calculate its sensitivity index, such as sensitivity coefficient and sensitivity interval. Rank the monitoring indicators according to the sensitivity index to obtain key influencing factors and provide support for the adjustment of the construction plan. Step d: Input the real-time data into the trained LSTM model and multivariate statistical model to obtain real-time prediction results. A corresponding construction plan is formulated based on the prediction results. The plan is simulated using the structural design module 501 to make the output plan more feasible. The plan is converted into instructions and sent to the workers' mobile phones or wearable devices via a wireless protocol, such as the LoRa wireless protocol, to make timely construction adjustments. Step d1: Extract prediction results from the LSTM model, extract the results of regression analysis, principal component analysis, and sensitivity analysis, use the test set to compare the prediction results of each model with the actual values, evaluate the prediction accuracy of each model, and calculate the performance index; The parameter settings of the LSTM model are as follows: the input layer has 8 nodes (corresponding to displacement and stress sensor data), the hidden layer has 2 layers, and the output layer has 3 nodes (predicting displacement / stress / safety factor). The training data comes from the monitoring history library of 10 super-high chimney projects, the sampling frequency is 10 Hz, the activation function is ReLU, the optimizer is Adam (learning rate 0.001), the loss function is mean square error, and the multiple regression uses the LASSO algorithm with a regularization coefficient λ=0.01. Step d2: weighted average the models based on the performance values and give each model a weight based on expert experience; Step d3: The prediction results of each model are multiplied by the corresponding weights and then summed up. The average is performed using a simple weighted average method to obtain the fused prediction result. Step e: continuously monitor the construction and repeat steps a to d until the construction is completed.
[0027] In an embodiment of the present invention, a plurality of cross bars 103 are provided on one side of the outer frame 101, and the cross bars 103 are screwed to the outer frame 101. A connecting groove for connection is preset at the upper end of the outer frame 101, and an auxiliary rod 104 is screwed to the inner side of the outer frame 101. The auxiliary rod 104 is used to connect to the template, and the template is installed on the auxiliary rod 104 and the cross bar 103 through a connecting rod to fix the position. A plurality of diagonal braces are welded between the auxiliary rod 104 and the bottom of the outer frame 101 and the base frame 102.
[0028] Specifically, the frame 100 is installed: When installing the first frame section, pre-set the fixing part 400 on the base frame 102, and fix and remove it from the foundation by rotating the mounting nut 401. The fixing part 400 is only used for the first frame section and can be disassembled and recycled after the construction is completed.
[0029] Subsequent frame installation: pre-embed the connectors in the cast chimney wall, anchor the frame 100 to the wall through the wall support (tensile strength ≥ 150% of the design value), and connect each layer of the frame outer frame 101 to the lower layer through bolts.
[0030] In an embodiment of the present invention, the control rod 202 is screwed to the movable plate 203, and a top block 204 adapted to the force block 206 is provided at the bottom of the movable plate 203, and the top block 204 is fixedly connected to the movable plate 203. Ejection ends 208 are fixed on both sides of the upper end of the movable plate 203, and the ejection ends 208 are made of rubber. A through groove 209 adapted to the ejection ends 208 is provided on the surface of the shell 201. The two ends of the spring 207 are fixedly connected to the shell 201 and the force block 206 respectively. The spring 207 surrounds the outside of the force block 206, and the force block 206 is threadedly engaged with the fixed block 205. A protrusion is provided inside the shell 201, and the protrusion is located above the fixed block 205. The spring 207 is fixed on the protrusion, and the bottom end of the force block 206 is threadedly engaged with the fixed block 205, and the force block 206 moves inside the protrusion.
[0031] Specifically, in the initial state, the spring 207 is in a natural state, and the ejection end 208 is located inside the housing 201. When the adjacent cross bars 103 need to be connected, the control rod 202 is pressed to press the movable plate 203 below the control rod 202 downward. At the same time, the ejection block 204 below the movable plate 203 applies a force to the force block 206. The force block 206 moves downward to compress the spring 207. Subsequently, the control rod 202 is rotated to move the ejection end 208 to the through slot 209, and the control rod 202 is released. When the external pressure is released, the spring 207 rebounds and pushes the force-bearing block 206 upward. The force-bearing block 206 transmits the thrust to the movable plate 203 through the top block 204, causing the rubber ejection ends 208 on both sides of the movable plate 203 to extend outward along the through groove 209 and clamp the inner wall of the housing 201 to achieve locking. The contact area of the top block 204 is larger than the conduction area of the force-bearing block 206 (for example, the area of the top block 204 is 1.5 times that of the force-bearing block 206). Therefore, a smaller deformation of the spring can drive the ejection ends 208 to produce a larger displacement. Moreover, when locking, the control rod 202 is pressed down to drive the movable plate 203, and the top block 204 pushes the force block 206 to compress the spring 207. After release, the spring 207 rebounds and pushes the movable plate 203 up through the top block 204, so that the rubber ejection end 208 forms a static friction lock with the inner wall of the shell 201.
[0032] In an embodiment of the present invention, a plug-in post 301 is fixed to the outer side of each of the two shells 201, a groove 302 is provided at the rear end of the plug-in post 301, a socket 303 adapted to the plug-in post 301 is provided on the inner side of the cross bar 103, the cross section of the fixing rod 304 is an "H"-shaped design, rubber blocks are fixed at the upper and lower ends of the fixing rod 304, and a through hole 305 adapted to the fixing rod 304 is provided on the surface of the cross bar 103 and the plug-in post 301.
[0033] Specifically, the plug post 301 is inserted into the socket 303 of the cross bar 103, and a convex strip adapted to the groove 302 is fixed in the socket 303. After the groove 302 of the plug post 301 engages with the convex strip in the cross bar 103, the fixing rod 304 is inserted along the through hole 305, and the rubber block at the lower end of its H-shaped cross section is clamped to realize the connection between the locking mechanism 200 and the cross bar 103. The locking mechanism 200 is connected through the connecting column, and the operation is simpler, and there is no need to directly contact the cross bar 103, so that the connection between the locking mechanism 200 and the cross bar 103 is more stable, avoiding wear and loosening caused by direct contact.
[0034] It should be noted that in order to avoid structural conflict of the fixing rod 304, the protrusion is located on the side wall of the socket 303, the groove 302 is located at the bottom of the column 301, and the H-shaped horizontal edge of the fixing rod 304 avoids the installation position of the protrusion to avoid interference.
[0035] In an embodiment of the present invention, the expansion sleeve 403 is made of 34CrMo alloy steel and is surface carburized to ensure plastic deformation capability. A movable joint 404 for expansion is provided on the outside of the expansion sleeve 403. The bottom end of the screw 403 is provided with a protruding head 405 for propping up the movable joint 404 at the expansion sleeve 403. When the mounting nut 401 is tightened to drive the screw 402 upward, the protruding head 405 at the bottom end of the screw is wedged into the movable joint 404, causing the expansion sleeve 403 to deform and cooperate with the foundation hole wall. The expansion sleeve 403 needs to be replaced after deformation.
[0036] Specifically, after the basic structure of the mold frame 100 is installed, the fixing member 400 is connected to the base frame 102, and the base frame 102 is firmly fixed by the coordinated action of the installation nut 401, the screw 402 and the expansion sleeve 403.
[0037] Example 2:
[0038] Refer to the attached Figure 8 As shown, an embodiment of the present invention further provides a construction method for an ultra-high chimney formwork frame structure, comprising the following steps: S1. Based on the design plan of the super-high chimney, the staff, combined with their own experience, conducts a preliminary design of the flip formwork frame 100 structure. During the design process, factors such as the chimney height, diameter, structural characteristics, and construction environment must be fully considered. The design parameters are then input into the structural design module 501 for simulation analysis. The simulation obtains the stress conditions, stability, and potential safety risks of the frame 100 at different construction stages. Based on the simulation results, the design plan is optimized to ensure the safety and reliability of the flip formwork frame 100 during construction. When the flip formwork frame design system 500 is not enabled, a manual design verification process is executed. S2. Before construction, conduct a detailed site survey to ensure the site meets construction requirements. Then, according to the optimized design, drill holes in the foundation and insert screws 402. Install fixtures 400. Assemble the base frame 102, crossbars 103, and locking mechanism 200. Pre-embed connectors in the hardened chimney wall. Anchor the frame 100 to the wall using wall mounts. Test the pullout resistance of the wall mounts. S2a, first section installation, assemble the base frame 102, crossbar 103 and locking mechanism 200, fix them on the foundation through the fixing parts 400, and then install the frame, anchor the frame to the chimney wall through the wall support. S3. During the construction process, sensors are used to monitor the installed flip formwork frame 100 in real time. The monitored data includes displacement, stress, deformation, and other key parameters of the frame 100. The data analysis module 503 performs trend analysis on the monitored data. For example, by analyzing the trend of displacement data, the stability of the frame 100 can be predicted. By analyzing the trend of stress data, the load-bearing capacity of the frame 100 can be evaluated. Based on the analysis results, potential safety hazards can be discovered in a timely manner and corresponding solutions can be provided. S4. Based on the monitoring data and analysis results obtained in step S3, the staff will make timely adjustments to the construction plan. The adjustments may include the arrangement of construction progress, optimization of construction methods, strengthening of safety measures, etc. Under the guidance of the adjusted construction plan, the staff will continue construction until the construction of the super-high chimney is completed. During the construction process, continuous monitoring and data analysis are required to ensure the effectiveness and safety of the construction plan.
