Description

Technical Field

[0001] This invention relates to the fields of building construction and temporary erection technology, specifically to an adaptive multi-scaffolding system and method for constructing irregular structures. Background Technology

[0002] As a core temporary support structure in building construction, stage construction, and temporary exhibitions, the quality of scaffolding construction directly affects construction safety, construction efficiency, and usage costs. With the diversified development of modern engineering design, the application of irregular structures (such as curved building facades, irregularly shaped stages, and customized exhibition installations) is becoming increasingly widespread, placing higher demands on the adaptability, flexibility, and safety of scaffolding.

[0003] However, existing technologies have many shortcomings:

[0004] Poor adaptability: Traditional scaffolding (such as coupler type and cup buckle type) is mainly designed for regular structures such as rectangles and cylinders. The components have low versatility. For irregular structures, special components need to be customized, resulting in high construction costs, long cycle and low component reuse rate.

[0005] Low construction efficiency: The construction of scaffolding for irregular structures relies on manual on-site measurement and hand-drawn plans to plan the distribution of nodes. This is not only labor-intensive, but also prone to insufficient construction accuracy due to human error, requiring repeated adjustments later.

[0006] Insufficient safety: Traditional construction methods rely on manual experience for node layout and component selection, lacking precise analysis of the mechanical properties of irregular structures. This can easily lead to problems such as uneven stress on nodes and insufficient overall stability, posing safety hazards.

[0007] Limitations in scenario adaptation: Existing technologies are unable to simultaneously meet the differentiated needs of different scenarios such as building construction (high load-bearing capacity, high stability), stage construction (rapid assembly and disassembly, lightweight), and temporary exhibitions (flexible adjustment, aesthetics), and lack an adaptive adjustment mechanism.

[0008] Therefore, how to provide a scaffolding construction solution that can accurately adapt to irregular structures, meet the needs of multiple scenarios, and improve construction efficiency and safety has become a technical problem that the industry urgently needs to solve.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0084] The present invention will be further described in detail below with reference to the accompanying drawings.

[0085] Reference Figure 1 In a first aspect, the present invention provides an adaptive multi-scene irregular structure scaffolding erection method, comprising the following steps:

[0086] Collect the irregular structure parameters and environmental constraint parameters of the target scene;

[0087] A three-dimensional model of the irregular structure is constructed based on the aforementioned irregular structure parameters;

[0090] The initial scaffolding model is dynamically optimized using a multi-objective optimization algorithm to obtain the optimal construction scheme.

[0091] The scaffolding is assembled automatically or semi-automatically according to the optimal assembly scheme.

[0092] It should be noted that this invention achieves adaptive construction of irregularly shaped scaffolding in multiple scenarios through six core steps. First, it collects the irregularly shaped structural parameters and environmental constraint parameters of the target scenario to obtain the structural geometric characteristics, mechanical properties, and scene limitations. Based on the collected parameters, a 3D model of the irregularly shaped structure is constructed to accurately reproduce its form. Then, based on the 3D model and environmental constraints, a scaffolding node distribution scheme adapted to the irregularly shaped structure is generated, clarifying the node positions and connection relationships. Based on the node distribution scheme, suitable scaffolding components are matched from the component database to construct an initial construction model. The initial model is dynamically optimized using a multi-objective optimization algorithm to balance safety, stability, economy, and construction efficiency, resulting in the optimal construction scheme. Finally, based on the optimal scheme, automated equipment or AR-guided manual execution of the scaffolding construction operation is used.

[0093] This invention breaks through the limitations of traditional scaffolding construction, which relies on manual experience and is only suitable for regular structures. Through an integrated process of parameter collection, precise modeling, intelligent node generation, component matching, and multi-objective optimization, it achieves adaptive adaptation to irregular structures in various scenarios such as building construction, stage construction, and temporary exhibitions. It significantly improves the personalization and accuracy of construction while taking into account safety, efficiency, and cost. It provides a systematic and intelligent solution for the construction of irregular structure scaffolding, solving the core problems of poor adaptability, low efficiency, and insufficient safety of existing technologies.

[0094] In some embodiments, collecting the irregular structure parameters and environmental constraint parameters of the target scene specifically includes:

[0095] Three-dimensional point cloud data of the irregular structure is collected by a lidar sensor, and geometric parameters are extracted, including contour dimensions, surface curvature, and coordinates of key control points.

[0096] Environmental image data of the target scene is collected by a visual sensor, and environmental constraint parameters are extracted. The environmental constraint parameters include the location of spatial obstacles, the available building space range, and the lighting conditions.

[0097] Mechanical parameters of the irregularly shaped base structure are collected by strain gauge sensors. These mechanical parameters include load-bearing limit and vibration frequency.

[0098] The Kalman filter algorithm is used to fuse the geometric parameters, environmental constraint parameters, and base mechanical parameters to remove noise data and obtain a standardized parameter set.

[0099] In practice, a multi-source sensor collaborative data acquisition method is adopted. The lidar sensor collects 3D point cloud data of the irregular structure and extracts geometric parameters such as contour size and surface curvature. The vision sensor collects scene environment image data and obtains environmental constraint parameters such as obstacle position and available space. The strain gauge sensor collects mechanical parameters such as the load-bearing limit and vibration frequency of the structural base. Then, the Kalman filter algorithm is used to fuse the data collected by the multi-source sensors. Data noise is removed through state update and measurement update equations, and a standardized parameter set is output to provide accurate and reliable data support for subsequent modeling and scheme design.

[0100] This invention achieves comprehensive coverage of information on irregular structures and scenes through the collaborative acquisition of data from multiple sources of sensors, avoiding the limitations of data collected by a single sensor. The application of the Kalman filter algorithm effectively filters out data noise, improves the accuracy and reliability of parameter data, ensures the precision of subsequent steps such as 3D modeling and node planning, lays a data foundation for the rationality and safety of the overall construction scheme, and reduces construction adjustments or safety hazards caused by data errors.

[0101] In some embodiments, constructing a three-dimensional model of the irregular structure based on the irregular structure parameters specifically includes:

[0102] Extract feature control points of the irregular structure from the standardized parameter set. , ; Where m and n are the number of control points in the u and v directions, respectively;

[0103] The three-dimensional model of the irregular structure is constructed using the Bézier surface equation, which is:

[0104] ;

[0105] in, , Let be m-th degree Bessel basis functions, satisfying:

[0106] ;

[0107] in, Let be a combination number, satisfying: ;

[0108] The 3D point cloud data is fitted to a surface using the least squares method, and the feature control points are iteratively optimized. The coordinates of the model reduce the geometric error between the 3D model and the actual irregular structure. 0.5mm.

[0109] It should be noted that feature control points of the irregular structure are extracted from the standardized parameter set. Based on the control points, a three-dimensional model is constructed using the Bézier surface equation. By calculating the Bézier basis function and combinatorial number, flexible fitting of the complex surface is achieved. The least squares method is used to optimize the surface fitting of the three-dimensional point cloud data. The coordinates of the feature control points are iteratively adjusted to minimize the geometric error between the model and the actual structure, ensuring that the three-dimensional model can accurately reproduce the actual shape of the irregular structure, and the geometric error is controlled within the preset range.

[0110] This invention utilizes Bézier surface modeling technology to accurately fit irregularly shaped structures with any complex form, solving the problem that traditional modeling methods struggle to reproduce irregular surfaces. The fitting optimization process further improves model accuracy, ensuring that the geometric errors between the 3D model and the actual structure meet the construction requirements. This provides a precise structural reference for subsequent node distribution and component matching, ensuring the fit between the scaffolding and the irregular structure, and enhancing the stability and reliability of the construction.

[0111] In some embodiments, generating an adaptive scaffold node distribution scheme for the irregular structure specifically includes:

[0112] Surface curvature based on the three-dimensional model Determine node density It satisfies the dynamic density equation:

[0113] ;

[0114] in, Reference node density ( ), The curvature coefficient ( );

[0115] Establish a set of force equilibrium equations for the nodes, the set of equations being:

[0116] , , , , , ;

[0117] in, , , The nodes are respectively , , The resultant external force in the direction, , , For each node , , The net external torque on the shaft;

[0118] Solving the system of force equilibrium equations yields the optimal spatial coordinates of each node. ;

[0119] Construct a node connection matrix ,in Represents a node With nodes There is a connection. This indicates no connection relationship, and the connection relationship satisfies the overall stability constraint of the scaffold (overturning coefficient). Bearing capacity safety factor ).

[0120] In practical implementation, based on the surface curvature of the 3D model, the node density is determined through a dynamic density equation. The greater the surface curvature, the higher the node density, ensuring the support strength in complex structural areas. A set of node force balance equations is established, considering various forces such as gravity, wind load, and construction load, to obtain the optimal spatial coordinates of each node. A node connection relationship matrix is ​​constructed to clarify the connection logic between nodes, while simultaneously meeting the constraints of the overturning resistance coefficient and the bearing capacity safety factor, ensuring that the node distribution adapts to the irregular structural form and guarantees the overall stability of the scaffolding. The dynamic adjustment of node density enables precise adaptation to the support needs of different areas of the irregular structure, avoiding insufficient local support or resource waste caused by uniform distribution. Force balance analysis and stability constraints ensure the mechanical rationality of the node distribution, keeping the force on each node in a balanced state, improving the overall stability and bearing capacity of the scaffolding, reducing the risk of overturning, and providing core protection for safe use after construction.

[0121] In some embodiments, matching the corresponding scaffolding components based on the node distribution scheme specifically includes:

[0122] Establish a database of scaffolding components, including telescopic support rods (length adjustment range 1-3m, load-bearing capacity 1-5t) and adaptive rotating connectors (rotation angle). Torsional stiffness Adjustable base (height adjustment range 0-20cm, horizontal adjustment accuracy) 0.1mm);

[0123] Based on the node type (corner node, load-bearing node, ordinary node) and the force on the node. The K-nearest neighbor algorithm (K=3) is used to match the optimal component from the component database. The matching criteria are as follows:

[0124] ;

[0125] in, Weighting coefficients ( , , ), For the k-th parameter of the component, For the k-th requirement parameter of the node;

[0126] Based on the matching results, an initial scaffolding model is constructed to clarify the installation positions, connection methods, and tightening torques of the components.

[0127] In practical implementation, a scaffolding component database is pre-established, containing core components such as retractable support rods, adaptive rotating connectors, and adjustable bases. Each component is associated with parameters such as dimensions, load-bearing capacity, stiffness, and compatible node type. Based on the node type (corner node, load-bearing node, ordinary node) and stress conditions, the K-nearest neighbor algorithm (K=3) is used for component matching. With load-bearing capacity, size, and stiffness compatibility as core criteria, the compatibility deviation between the component and node requirements is calculated through weight allocation, and the component with the smallest deviation is selected as the optimal matching component. Based on the matching results, the component installation position, connection method, and tightening torque are determined, and an initial scaffolding erection model is constructed. The establishment of the component database enables standardized management of scaffolding components and improves component reusability. The application of the K-nearest neighbor algorithm ensures accurate matching between components and node requirements, avoiding insufficient support or resource waste caused by improper component selection. The clear initial erection model provides a clear operational basis for subsequent optimization and erection execution, reducing uncertainty in the erection process, improving erection efficiency and quality, and simultaneously reducing component wear and erection costs.

[0128] In some embodiments, dynamically optimizing the initial scaffolding model using a multi-objective optimization algorithm specifically includes:

[0129] The multi-objective optimization function is determined, with optimization objectives including safety (S), stability (T), economy (C), and construction efficiency (E). The fitness function is:

[0131] in, , , , ,and ;

[0132] The security S satisfies:

[0133] ;

[0134] in; For the maximum force on the node, Rated load capacity of the component;

[0135] The stability T satisfies:

[0136] ;

[0137] Where d is the offset of the scaffold's center of gravity. To allow the maximum offset ( );

[0138] The economic efficiency C satisfies:

[0139] ;

[0140] in, Let $\frac{k}{k}$ be the unit price of the component of type k. The number of components of type k used;

[0141] The construction efficiency E satisfies:

[0142] ;

[0143] in; Total setup time;

[0144] use A multi-objective optimization algorithm is used to find the Pareto optimal solution, and the scheme with the largest overall fitness F is selected as the optimal construction scheme.

[0145] It should be noted that the core objectives of multi-objective optimization are clearly defined, including safety, stability, economy, and construction efficiency. A comprehensive fitness function is constructed, and the importance of each objective is balanced through weight allocation. Safety is calculated based on the ratio of the maximum force on a node to the rated load of a component; stability is calculated based on the scaffolding's center of gravity offset; economy is the total procurement cost of components; and construction efficiency is the total construction time. A multi-objective optimization algorithm is used to find the Pareto optimal solution. By setting parameters such as population size, number of iterations, crossover probability, and mutation probability, the algorithm selects the scheme with the highest overall fitness as the optimal construction scheme. This invention achieves a balance between the core performance aspects of the construction scheme through a multi-objective optimization algorithm, avoiding the trade-offs caused by single-objective optimization (such as sacrificing security for the sake of minimum cost). The algorithm can efficiently solve multi-objective optimization problems. The optimal solution output takes into account safety, stability, economy and construction efficiency, ensuring that the overall performance of the construction solution is optimal. It not only meets the safety requirements, but also controls costs, improves efficiency, and enhances the practicality and promotion value of the solution.

[0146] In some embodiments, the automated or semi-automated erection of the scaffolding according to the optimal erection scheme specifically includes:

[0147] During automated assembly, the robotic arm performs component installation. Based on the coordinate information of the optimal assembly scheme, the attitude parameters of the robotic arm's end effector are calculated using inverse kinematics. The inverse kinematics equations are as follows: ;

[0148] in, This is the joint angle vector of the robotic arm. For Jacobian matrices, for The pseudo-inverse matrix, This is the spatial position vector of the end effector;

[0149] During semi-automated assembly, AR devices are used to overlay a 3D model of the optimal assembly plan onto the real-world scene, guiding workers to install step by step in real time.

[0150] The installation accuracy is detected in real time using a vision sensor, and when the component installation deviation occurs... When the deviation is 1mm, an audible and visual warning will be issued, and a deviation correction suggestion will be output.

[0151] It should be noted that during automated assembly, based on the coordinate information of the optimal assembly plan, the joint angle vectors of the robotic arm are calculated through inverse kinematics equations. This controls the end effector of the robotic arm to install components according to preset postures and positions, ensuring installation accuracy. During semi-automated assembly, an AR device overlays a 3D model of the optimal assembly plan onto the real-world scene, displaying the component installation sequence, position markers, and operation instructions in real time, guiding workers to perform the installation step by step. During the assembly process, visual sensors monitor the component installation accuracy in real time. When the deviation exceeds a preset threshold, an audible and visual warning is issued, along with deviation correction suggestions, ensuring installation quality. The automated assembly mode significantly improves assembly efficiency and reduces manual labor intensity, while the high-precision operation of the robotic arm ensures the accuracy of component installation. The AR-guided semi-automated assembly mode balances flexibility and accuracy, making it suitable for complex areas or scenarios where automated equipment is difficult to operate, reducing reliance on workers' professional skills. The real-time accuracy detection and warning mechanism can promptly detect and correct installation deviations, avoiding the accumulation of deviations that could lead to overall assembly quality problems, and ensuring the installation accuracy and safety of the scaffolding.
