Description

Technical Field

[0001] The present application relates to the technical field of stress-bearing engineering projects of flower basket scaffolds, and more specifically, to a method and system for analyzing stress characteristics and deformation of flower basket scaffolds. Background Art

[0002] Flower basket scaffolding is a common temporary support structure for construction and is widely used in high-rise building construction. However, the force analysis and deformation control of flower basket scaffolding in the prior art are still insufficient. The force characteristics and deformation analysis methods of the system are basically not involved. Therefore, the present invention aims to provide a comprehensive analysis method and system for optimizing the design and use of flower basket scaffolding. Summary of the invention

[0003] The present invention aims to provide a method and system for analyzing the stress characteristics and deformation of a flower basket scaffold. By establishing a three-dimensional finite element model and combining the load and boundary conditions of actual working conditions, the scaffold is accurately analyzed for stress and deformation, and the scaffold structure design is optimized according to the analysis results. This solves the problem that the prior art proposes an adjustable structure but does not involve the stress characteristics and deformation analysis method of the system.

[0004] To achieve the above object, the present invention provides the following technical solutions: A method for analyzing the stress characteristics and deformation of a flower basket scaffold comprises the following steps: S1: Establish a three-dimensional finite element model of the flower basket scaffolding, including cantilever steel beams, diagonal rods, flower basket bolts and anchor points; S2: Apply loads and boundary conditions according to actual working conditions; S3: Calculate the stress distribution and deformation of each component through finite element analysis; S4: Optimize the scaffolding structure design based on the calculation results; In this process, the finite element model of the cantilever steel beam is generated using professional finite element modeling software (such as ANSYS, ABAQUS, etc.) based on the actual size of the cantilever steel beam, material properties (such as elastic modulus, Poisson's ratio, etc.) and support conditions. This model needs to accurately simulate the structural characteristics of the cantilever steel beam, including its cross-sectional shape, size and connection method.

[0005] The diagonal brace is an important load-bearing component in the flower basket scaffolding. When modeling, factors such as the length, cross-sectional area, material properties, and connection position of the diagonal brace need to be considered. Finite element software can be used to generate a finite element model of the diagonal brace and simulate its mechanical behavior during the force process.

[0006] As an adjustment component in the scaffolding, the modeling of the turnbuckle is equally important. It is necessary to generate a corresponding finite element model based on the geometric dimensions, material properties, and connection methods of the turnbuckle. This model needs to be able to simulate the adjustment function and mechanical behavior of the turnbuckle during the stress process.

[0007] The anchor point is the key part of the connection between the scaffolding and the building or other structures. When modeling, it is necessary to accurately simulate the location of the anchor point, the constraints (such as fixed end constraints, hinged end constraints, etc.) and the connection method. This helps to ensure the accuracy and reliability of the finite element analysis.

[0008] Preferably, in step S1, the stress calculation formula of the cantilever steel beam is: Among them, σ is the stress of the cantilever steel beam, M is the bending moment, W is the section modulus, F is the tension of the diagonal rod, L is the cantilever length, E is the material elastic modulus, and I is the section moment of inertia; On the other hand, in case of cantilever beam, since one end is fixed and the other end is freely suspended, it is subjected to bending moment, which causes stress in the beam.

[0009] For a cantilever steel beam with a rectangular cross-section, the calculation formula for its normal stress (bending stress) can be expressed as: in: is the normal stress at a point on the beam cross section; is the bending moment at the cross section at that point; is the distance from that point to the neutral axis of the beam (in a rectangular section, this is the distance from the bottom or top of the beam to the neutral axis, depending on whether you are considering the tension or compression zone); is the section moment of inertia of the beam. For a rectangular section, its calculation formula is ,in is the width of the cross section, is the height of the section.

[0010] However, in the case of cantilever beams, since the bending moment varies along the length of the beam (especially in the overhanging section), a more complex analysis is usually required to determine the distribution of the bending moment along the length of the beam. This usually involves a static analysis in structural mechanics, and may require the use of the finite element method or other numerical methods to obtain accurate results.

[0011] In addition, for steel beams, the material's yield strength and other material-related properties also need to be considered to ensure that the design meets safety requirements.

[0012] In practical applications, engineers usually use professional structural analysis software or tables and charts in manuals to assist in the calculation and design of cantilever steel beams. These tools provide simplified methods based on extensive testing and experience to quickly and accurately evaluate the stress and deformation of beams.

[0013] So in summary It is a relatively good calculation method that takes multiple aspects into consideration. However, in actual applications, multiple calculation methods will be used in combination. This is only a relatively preferred choice.

[0014] Preferably, in step S3, the deformation calculation formula of the inclined tie rod is: Among them, ΔL is the deformation of the inclined rod, F is the tension, L is the length of the inclined rod, A is the cross-sectional area, E is the elastic modulus of the material, α is the thermal expansion coefficient of the material, ΔT is the temperature change, and ν is the Poisson's ratio.

[0015] In step S2, the loads include vertical loads, horizontal loads and wind loads, and the boundary conditions include fixed end constraints and hinged end constraints.

[0016] Vertical loads mainly include the weight of the scaffolding itself, the weight of materials placed on the scaffolding, the weight of construction workers and equipment, etc.

[0017] These loads usually act vertically on the various components of the scaffolding and are the main factors causing vertical deformation and stress in the scaffolding.

[0018] Horizontal loads come from many aspects, such as horizontal thrust during construction, horizontal force caused by wind load, etc.; horizontal loads are crucial to the stability of scaffolding, especially in high-rise buildings or complex construction environments.

[0019] Wind load is a factor that cannot be ignored in scaffolding design, especially in open areas or areas with high wind speeds. The magnitude and direction of wind loads may change over time, so when performing finite element analysis, it is usually necessary to consider the effects of dynamic wind loads.

[0020] In some embodiments, in fact, we automatically calculate the deadweight of the flower basket scaffolding by the density and volume of the flower basket scaffolding material in practice; Determine the load of construction personnel and materials according to the actual construction situation; By formula Calculate the wind load; where P is the wind load, is the wind vibration coefficient at height z, is the coefficient of variation of wind pressure height at height z; is the wind load shape coefficient of the flower basket scaffolding; The basic wind pressure.

[0021] Fixed end restraints are usually applied to the bottom of the scaffolding or where it is connected to other structures.

[0022] At the fixed end, the displacement of the scaffold is completely restricted, that is, no movement or rotation in any direction can occur.

[0023] The hinged end constraint allows the scaffold to rotate in a certain direction but restricts movement in other directions.

[0024] This constraint is usually applied to the connection points between the scaffolding and other structures, or to certain connection parts inside the scaffolding.

[0025] When conducting finite element analysis, it is necessary to accurately simulate these loads and boundary conditions. This involves applying corresponding forces and constraints in the finite element model and setting reasonable analysis parameters. By accurately simulating these conditions, the accuracy and reliability of the analysis results can be ensured, thus providing strong support for the structural design of the scaffolding.

[0026] In step S4, the optimization design includes adjusting the angle of the diagonal tie rod, increasing the number of anchor points and optimizing the cross-sectional size of the cantilever steel beam; Adjusting the angle of the diagonal brace has a significant impact on the stability and load-bearing capacity of the scaffolding. The angle of the diagonal brace determines its stress state, and a reasonable angle can enable the diagonal brace to bear and transfer loads more effectively.

[0027] lBy adjusting the angle of the diagonal tie rod, its stress state can be optimized and the overall stability and load-bearing capacity of the scaffolding can be improved. This helps to reduce the deformation and stress concentration of the scaffolding during the stress process, thereby extending its service life.

[0028] In actual operation, it is necessary to determine the optimal angle of the diagonal brace through calculation and simulation according to the specific structure and stress conditions of the scaffolding. Then, the angle can be adjusted by adjusting the connection points of the diagonal brace or adding additional connectors.

[0029] Increasing the number of anchor points is another effective way to improve the stability and load-bearing capacity of scaffolding. Anchor points are key parts that connect scaffolding to buildings or other structures, and their number and location have a significant impact on the overall performance of the scaffolding.

[0030] Increasing the number of anchor points can more effectively transfer the load of the scaffolding to the building or other structure, thereby improving its stability. At the same time, this also helps to reduce the deformation and displacement of the scaffolding during the force process, ensuring its safety during use.

[0031] When increasing the number of anchor points, it is necessary to consider the structural characteristics of the scaffolding, the stress conditions and the bearing capacity of the building or other structure. Through reasonable layout and connection methods, ensure that the newly added anchor points can play an effective role.

[0032] Cantilever steel beams are one of the important load-bearing components in scaffolding. By optimizing the cross-sectional dimensions of cantilever steel beams, they can have better rigidity and stability while meeting the load-bearing requirements. This helps reduce the deformation and vibration of the scaffolding during the stress process and improve its overall performance.

[0033] When optimizing the cross-sectional dimensions of cantilever steel beams, factors such as stress state, material properties, and manufacturing process need to be considered. Through reasonable calculations and simulations, the optimal cross-sectional dimensions and shapes are determined to ensure that the cantilever steel beams can effectively bear and transfer loads.

[0034] It is necessary to formulate a detailed optimization design plan based on the specific conditions and force requirements of the scaffolding, and verify its effectiveness through calculation and simulation.

This module includes the following components: Cantilever steel beam modeling unit, which generates a finite element model of the cantilever steel beam according to the input cantilever steel beam size, material properties and support conditions, accurately simulates the structural characteristics of the cantilever steel beam, and provides a basis for subsequent analysis.

[0037] The diagonal tie rod modeling unit generates a finite element model of the diagonal tie rod according to its length, cross-sectional area, material properties and connection position, simulates the mechanical behavior of the diagonal tie rod and provides support for force analysis.

[0038] The turnbuckle modeling unit generates a finite element model of the turnbuckle according to its geometric dimensions, material properties and connection methods, and simulates the adjustment function and mechanical behavior of the turnbuckle.

[0039] The anchor point modeling unit generates a finite element model of the anchor point according to the position and constraint conditions (such as fixed end and hinged end) of the anchor point, simulates the constraint effect of the anchor point, and ensures the accuracy of the boundary conditions of the model.

[0040] The calculation and analysis module is used to perform stress and deformation analysis on the established finite element model. The module includes: a stress calculation unit, which calculates the stress distribution of each component according to the finite element model and the applied load, identifies the stress concentration area, and provides a basis for structural optimization; a deformation calculation unit, which performs deformation analysis calculation according to the finite element model.

[0041] The result optimization module includes a structure optimization unit and a parameter adjustment unit. The structure optimization unit adjusts the structural parameters of the scaffolding, such as the angle of the diagonal brace, the cross-sectional size of the cantilevered steel beam, the number of anchor points, etc., according to the stress and deformation analysis results, so as to improve the force performance and stability of the scaffolding and reduce the construction risk. The parameter adjustment unit adjusts the parameters of each component, such as the cross-sectional area of ​​the diagonal brace, the adjustment length of the basket bolt, etc., according to the optimization plan, to ensure the feasibility of the optimization plan and improve the construction efficiency.

[0042] The data storage module includes the following components: a model data storage unit, which is convenient for users to view and modify the model at any time, a calculation result storage unit, which stores and retrieves the calculation results to provide a reference for subsequent analysis and optimization, and an optimization solution storage unit, which stores and retrieves the optimization solution to facilitate users to compare and select the best solution. The data storage module receives data from the model building module, the calculation analysis module and the result optimization module.

[0043] Compared with the prior art, the present invention has the following beneficial effects: 1. Based on the results of finite element analysis, the present invention can identify stress concentration areas and excessively deformed parts, thereby guiding the structural optimization design of the scaffolding. By adjusting the angle of the diagonal rod, increasing the number of anchor points, optimizing the cross-sectional size of the cantilevered steel beam, etc., the force-bearing performance and stability of the scaffolding can be effectively improved, and the safety risks during the construction process can be reduced.

[0044] 2. By establishing an accurate three-dimensional finite element model and combining the load and boundary conditions of actual working conditions, the present invention can accurately simulate the stress state of the flower basket scaffolding in actual construction, thereby calculating the stress distribution and deformation of each component. This accurate analysis method greatly improves the accuracy and reliability of stress characteristics and deformation analysis. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1: Application of the present invention in high-rise building construction: In the construction of a high-rise building, a flower basket scaffold is used as an external scaffold. The specific implementation steps are as follows: Step 1: Establish a 3D finite element model. According to the building structure and construction requirements, establish a 3D finite element model including cantilever steel beams, diagonal stays, basket bolts and anchor points. Input parameters include: The length of the cantilever steel beam is L = 5 meters, the cross-sectional dimensions are b × h = 200 × 400 mm², the material elastic modulus is E = 200 GPa, and the section moment of inertia is I = 1.33 × 10 7 mm 4 ; The length of the inclined rod is L=3 meters, the cross-sectional area is A=1000mm², and the material elastic modulus is E=200GPa; the diameter of the basket bolt is d=20mm, and the material elastic modulus is E=200GPa; the anchor point constraint type is fixed end.

[0049] Step 2: Apply loads and boundary conditions. Vertical load: weight of construction personnel and materials, applied as uniform load of q=2 kN / m²; Horizontal load: wind load applied as Fw=0.5 kN / m². Temperature change: Consider temperature difference ΔT=20°C, material thermal expansion coefficient α=1.2×10;−5 / °C. Boundary conditions: one end of the cantilever steel beam is fixed, and both ends of the diagonal rod are hinged.

[0050] Step 3: Calculate stress and deformation using finite element analysis software (such as ABAQUS) to obtain: The maximum stress of the cantilever steel beam is σ = 180MPa. The maximum deformation of the inclined rod is ΔL = 2.5mm.

[0051] Step 4: Optimize the structural design: According to the calculation results, adjust the angle of the diagonal tie rod to 75°, increase the number of anchor points, and optimize the cross-sectional dimensions of the cantilever steel beam. After optimization, the maximum stress of the cantilever steel beam is reduced to 150MPa, and the maximum deformation of the diagonal tie rod is reduced to 2mm, which significantly improves the stability and safety of the scaffolding.

[0052] First, a stress characteristic and deformation analysis system of a flower basket scaffolding is provided. In the model building module, a three-dimensional finite element model is established using professional finite element modeling software (such as ANSYS) according to the actual size and material properties of the flower basket scaffolding. The model includes key components such as cantilevered steel beams, diagonal stays, flower basket bolts and anchor points. During the modeling process, it is necessary to accurately simulate the structural characteristics and connection methods of each component to ensure the accuracy of subsequent analysis. In this embodiment, according to the actual size and material properties of the flower basket scaffolding, the various parameters of the cantilevered steel beams, diagonal stays, flower basket bolts and anchor points are recorded in detail. That is, the length of the cantilevered steel beam is L=5 meters, the cross-sectional dimensions are b×h=200×400 mm², the material elastic modulus is E=200GPa, and the section moment of inertia is I=1.33×10^7mm 4 ; The length of the inclined rod is L=3 meters, the cross-sectional area is A=1000mm², and the material elastic modulus E is also 200GPa; the diameter of the basket bolt is 20mm, and the material elastic modulus E=200GPa. The anchor point is set as a fixed end constraint. Using professional finite element modeling software (such as ANSYS), a three-dimensional finite element model containing all the above key components was constructed. When modeling, special attention was paid to the structural characteristics and connection methods of each component to ensure the accuracy and reliability of the model.

[0053] Then, in the load application module, loads and boundary conditions are applied according to the actual working conditions. Loads include vertical loads (such as the weight of the scaffolding itself, the weight of materials, etc.), horizontal loads (such as horizontal thrust during construction, wind loads, etc.) and wind loads. Boundary conditions include fixed end constraints and hinged end constraints, which are used to limit the displacement and rotation of the scaffolding. These loads and boundary conditions need to be specifically set and adjusted according to the actual situation. According to the actual situation during the construction process, vertical loads and horizontal loads are applied. The vertical load mainly includes the weight of the scaffolding itself, the weight of construction personnel and materials, etc., and is applied as a uniformly distributed load of q=2kN / m². The horizontal load includes the horizontal thrust and wind load during construction, among which the wind load is applied as F_w=0.5 kN / m². Considering the thermal expansion effect of the material due to temperature changes, the temperature difference ΔT=20°C and the material thermal expansion coefficient α=1.2×10^-5 / °C are also input. According to the actual constraints of the scaffolding, the boundary conditions of fixing one end of the cantilever steel beam and hinged both ends of the diagonal tie rod were set.

[0054] Next, in the calculation and analysis module, the established model is solved using finite element analysis software. The stress distribution diagram and deformation diagram of each component are obtained through calculation. These results can intuitively show the stress distribution and deformation of the scaffolding during the stress process, providing a basis for subsequent optimization design.

[0055] Finally, in the result optimization module, the scaffolding is optimized according to the analysis results of stress distribution and deformation. The force performance and stability of the scaffolding are improved by adjusting the angle of the diagonal rod, increasing the number of anchor points, and optimizing the cross-sectional size of the cantilevered steel beam. At the same time, it is also necessary to consider the actual situation of the construction site and factors such as construction efficiency to formulate a specific optimization plan, and verify its effectiveness through calculation and simulation. According to the results obtained by the calculation and analysis module, the scaffolding is optimized: Adjust the angle of the diagonal brace: The angle of the diagonal brace was adjusted to 75° to improve its stress performance. Increase the number of anchor points: By increasing the number of anchor points, we improved the overall stability of the scaffolding. Optimize the cross-sectional dimensions of the cantilever steel beam: The cross-sectional dimensions of the cantilever steel beam were optimized to reduce its stress level. After optimization, the maximum stress of the cantilever steel beam was reduced to 150MPa, and the maximum deformation of the diagonal brace was reduced to 2mm, which significantly improved the stability and safety of the scaffolding.

[0056] Finally, you can also set up a data storage module to store and manage model data, calculation results, optimization solutions, and other information. This makes it easy for users to view and modify models, retrieve and analyze calculation results, and compare and select the best solution at any time. With the support of the data storage module, the analysis efficiency and optimization effect can be further improved.

[0057] Embodiment 2: Application of the present invention in complex facade building construction: In the construction of a complex facade building, the scaffolding needs to adapt to different facade shapes. The specific implementation steps are as follows: Step 1: Create a 3D finite element model According to the shape of the building facade, a three-dimensional finite element model including cantilevered steel beams, diagonal stays and turnbuckle bolts is established. The input parameters are the same as those in Example 1, but the facade shape is complex and the anchor point position needs to be adjusted.

[0058] Step 2: Apply loads and boundary conditions. Vertical load: Apply uniform load of q=2kN / m².

[0059] Horizontal load: wind load is applied at Fw = 0.5kN / m²; temperature change: temperature difference ΔT = 20°C; Boundary conditions: One end of the cantilever steel beam is fixed, and both ends of the diagonal rod are hinged.

[0060] Step 3: Calculate stress and deformation. The calculation results show that the maximum stress of the inclined rod is σ=220MPa; The maximum deformation of the cantilever steel beam is ΔL=3.2mm.

[0061] Step 4: Optimize the structural design. According to the calculation results, adjust the cross-sectional dimensions of the cantilever steel beam, increase the number of diagonal tie rods, and optimize the layout of anchor points. After optimization, the maximum stress of the diagonal tie rods was reduced to 180MPa, and the maximum deformation of the cantilever steel beam was reduced to 2.8mm, ensuring the safety and stability of the scaffolding in complex environments.

[0062] First, a stress characteristic and deformation analysis system of a flower basket scaffolding is used in a model building module. According to the actual size and material properties of the flower basket scaffolding, a three-dimensional finite element model is established using professional finite element modeling software (such as ANSYS). The model includes key components such as cantilevered steel beams, diagonal stays, flower basket bolts and anchor points. During the modeling process, it is necessary to accurately simulate the structural characteristics and connection methods of each component to ensure the accuracy of subsequent analysis. In this embodiment, according to the actual size and material properties of the flower basket scaffolding, the various parameters of the cantilevered steel beams, diagonal stays, flower basket bolts and anchor points are recorded in detail. That is, the length of the cantilevered steel beam is L=5 meters, the cross-sectional dimensions are b×h=200×400mm², the material elastic modulus is E=200GPa, and the section moment of inertia is I=1.33×10^7mm 4 ; The length of the inclined rod is L=3 meters, the cross-sectional area is A=1000 mm², and the material elastic modulus E is also 200GPa; the diameter of the basket bolt is 20mm, and the material elastic modulus E=200GPa. The anchor point is set as a fixed end constraint. Using professional finite element modeling software (such as ANSYS), a three-dimensional finite element model containing all the above key components was constructed. When modeling, special attention was paid to the structural characteristics and connection methods of each component to ensure the accuracy and reliability of the model.

[0063] Then, in the load application module, loads and boundary conditions are applied according to the actual working conditions. Loads include vertical loads (such as the weight of the scaffolding itself, the weight of materials, etc.), horizontal loads (such as horizontal thrust during construction, wind loads, etc.) and wind loads. Boundary conditions include fixed end constraints and hinged end constraints, which are used to limit the displacement and rotation of the scaffolding. These loads and boundary conditions need to be specifically set and adjusted according to the actual situation. According to the actual situation during the construction process, vertical loads and horizontal loads are applied. The vertical load mainly includes the weight of the scaffolding itself, the weight of construction personnel and materials, etc., and is applied as a uniformly distributed load of q=2kN / m². The horizontal load includes the horizontal thrust and wind load during construction, among which the wind load is applied as F_w=0.5 kN / m². Considering the thermal expansion effect of the material due to temperature changes, the temperature difference ΔT=20°C and the material thermal expansion coefficient α=1.2×10^-5 / °C are also input. According to the actual constraints of the scaffolding, the boundary conditions of fixing one end of the cantilever steel beam and hinged both ends of the diagonal tie rod were set.

[0064] Next, in the calculation and analysis module, the established model is solved using finite element analysis software. The stress distribution diagram and deformation diagram of each component are obtained through calculation. These results can intuitively show the stress distribution and deformation of the scaffolding during the stress process, providing a basis for subsequent optimization design.

[0065] Finally, in the result optimization module, the scaffolding is optimized according to the analysis results of stress distribution and deformation. The force performance and stability of the scaffolding are improved by adjusting the angle of the diagonal rod, increasing the number of anchor points, and optimizing the cross-sectional size of the cantilevered steel beam. At the same time, it is also necessary to consider the actual situation of the construction site and factors such as construction efficiency to formulate a specific optimization plan, and verify its effectiveness through calculation and simulation. According to the results obtained by the calculation and analysis module, the scaffolding is optimized: Optimize the structural design, adjust the cross-sectional dimensions of the cantilever steel beams according to the calculation results, increase the number of diagonal tie rods, and optimize the layout of anchor points. After optimization, the maximum stress of the diagonal tie rods was reduced to 180MPa, and the maximum deformation of the cantilever steel beams was reduced to 2.8mm, ensuring the safety and stability of the scaffolding in complex environments.

[0066] Finally, you can also set up a data storage module to store and manage model data, calculation results, optimization solutions, and other information. This makes it easy for users to view and modify models, retrieve and analyze calculation results, and compare and select the best solution at any time. With the support of the data storage module, the analysis efficiency and optimization effect can be further improved.

[0067] The working principle of the invention: A method for analyzing the stress characteristics and deformation of a flower basket scaffold, through the collaborative work of the following modules, realizes accurate stress analysis and deformation evaluation of the flower basket scaffold, and provides an optimized design solution.

[0068] In addition, we can further deepen the implementation cases in practice.

[0069] Based on the above content, an intelligent analysis platform is developed, which can automatically receive the flower basket scaffolding parameters (such as size, material, connection method, etc.) input by the user, and automatically generate a three-dimensional finite element model based on these parameters. At the same time, the platform can integrate advanced AI algorithms, such as machine learning or deep learning models, to predict and optimize the stress performance and stability of the scaffolding (combined with machine learning or deep learning algorithms, an intelligent optimization algorithm is developed to automatically optimize the structural design of the scaffolding. The algorithm can automatically adjust the structural parameters of the scaffolding, such as the angle of the inclined rod, the cross-sectional size of the cantilevered steel beam, etc., according to the real-time collected data and the preset optimization goals, to achieve the best stress performance and stability. First, a large amount of scaffolding stress characteristics and deformation data are collected as training data sets. Then, the training data is trained using machine learning or deep learning algorithms to obtain an intelligent optimization model. In actual applications, the real-time collected data is input into the intelligent optimization model, and the model automatically outputs the optimized structural parameters.).

[0070] Real-time feedback and adjustment: During the analysis process, the platform can monitor and feedback the stress distribution and deformation of the model in real time, and automatically adjust the structural parameters of the scaffolding, such as the angle of the diagonal rod, the cross-sectional size of the cantilevered steel beam, etc., according to the analysis results to achieve the optimal stress state.

[0071] These are also very easy to implement. First, strain gauges, displacement sensors and stress sensors are installed on the key nodes and rods of the key parts of the flower basket scaffolding. Among them, the strain gauge is used to measure the strain data of the rod; the displacement sensor is used to measure the displacement data of the rod; the stress sensor is used to measure the stress data of the rod; Use temperature, humidity and wind speed sensors to collect environmental parameters at the construction site, including temperature, humidity and wind speed; The actual load data is monitored by load cells installed on the scaffolding; Record construction operation information during the construction process; Based on the strain data, displacement data, stress data, environmental parameters, actual load data and construction operation information of the rods, the original data of the flower basket scaffolding under actual working conditions is determined.

[0072] 1. Multi-condition analysis and optimization: Dynamic load simulation: In addition to considering static loads, the platform should also be able to simulate dynamic loads, such as wind loads, earthquake loads, etc., to evaluate the stress performance and stability of the scaffolding under different working conditions.

[0073] Multi-objective optimization: Based on the results of multi-condition analysis, the platform can execute a multi-objective optimization algorithm, taking into account multiple performance indicators (such as stress, deformation, stability, etc.) to find the optimal scaffolding design solution.

[0074] For example, in some embodiments, task analysis is performed on the flower basket scaffold under actual working conditions, specifically including: The stress distribution, strain distribution and displacement distribution of the flower basket scaffolding under static load are calculated by solving the finite element equilibrium equation. The natural frequency and vibration mode of the flower basket scaffolding are calculated by solving the eigenvalue problem formula; The time history analysis method and step-by-step integration method are used to solve the response of the scaffolding under dynamic loads.

[0075] In addition, we found that we can use virtual reality (VR) and augmented reality (AR) technology in the design, so that users can intuitively view and analyze the stress state and deformation of the scaffolding. This helps construction workers better understand the structural characteristics of the scaffolding and conduct sufficient verification and debugging before construction.

[0076] On the other hand, based on the virtual simulation results, we can further design and conduct physical verification experiments to verify the accuracy and reliability of the analysis results, which will help to further enhance the credibility of this method in practical applications.

[0077] The analysis platform is designed as a modular structure, with each module responsible for a specific function (such as model building, load application, calculation analysis, etc.). This design makes the platform easy to maintain and upgrade, and can be expanded according to user needs.

[0078] The platform should support integration with other software or systems, such as BIM (Building Information Modeling) system, construction management software, etc. This will help achieve seamless data sharing and collaborative work, and improve construction efficiency and quality.

[0079] At the construction site, sensors can be deployed to monitor the stress state and deformation of the scaffolding in real time. Based on these monitoring data, the platform can automatically adjust the structural parameters of the scaffolding to adapt to changes in the actual construction process.

[0080] When it is monitored that the stress state or deformation of the scaffolding exceeds the preset range (setting reasonable risk thresholds, such as stress limit values, deformation limit values, etc.), the platform can automatically issue an early warning signal to remind construction personnel to take necessary measures to ensure construction safety.

[0081] For example, in practice, the method we actually use to provide safety warnings for flower basket scaffolding is as follows: According to safety standards and specifications, different types of warning thresholds are set, including stress warning value, strain warning value and displacement warning value; the stress results, strain results and displacement results obtained by finite element analysis are compared with the corresponding warning thresholds respectively; The stress result YL obtained by finite element analysis is compared with the stress warning value YLZ of the material. If YL>YLZ, it is determined that the stress of the rod exceeds the allowable value, there is a safety hazard, and the warning signal is triggered immediately; otherwise, it is determined that the stress of the rod meets the safety standard; Compare the strain result YB with the specified displacement warning value YBZ. If YB>YBZ, it means that the strain on the scaffold exceeds the specified range, there is a safety hazard, and the warning signal is immediately triggered; otherwise, it means that the strain on the scaffold still meets the safety standards; Compare the displacement result WY with the specified displacement warning value WYZ. If WY>WYZ, it means that the deformation of the scaffolding exceeds the specified range, there is a safety hazard, and the warning signal is immediately triggered; otherwise, it means that the deformation of the scaffolding still meets the safety standards.

[0082] In the implementation case, we further found that machine learning algorithms, such as deep learning or reinforcement learning, can be integrated into the result optimization module to automatically analyze and optimize the scaffolding structure. These algorithms can predict the impact of different design parameters on the force performance and stability of the scaffolding by learning historical data and simulation results, thereby automatically proposing the optimal design solution. In addition, multi-objective optimization technology is introduced to consider multiple goals such as the force performance, stability, material cost, and construction efficiency of the scaffolding at the same time. These goals are automatically weighed by the algorithm to find the optimal design solution that meets all requirements. This multi-objective optimization mode is equivalent to the combination of the above embodiments. When implemented, only comprehensive calculations are required without additional design; in the design, we designed to take into account that the optimization module can automatically adjust the design parameters of the scaffolding according to the actual conditions of the construction site (such as wind speed, load changes, etc.), to ensure its safety and stability throughout the construction process.

[0083] For example, in some practical analysis, we can extract features from data; specifically, including but not limited to: Calculate the maximum, minimum, mean, median and variance of the strain data to determine the characteristics of the strain data; Calculate the maximum, minimum, mean, median and variance of stress data to determine the characteristics of stress data; Calculate the change rate of the displacement data measured by the displacement sensor to obtain the displacement data characteristics; Based on the strain data characteristics, stress data characteristics, displacement data characteristics, etc. obtained through calculation.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0085] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
