Description

Technical Field

[0001] This invention relates to the field of construction simulation technology, specifically a 3D simulation method for the construction of an ultra-large hyperbolic unitized glass curtain wall. Background Technology

[0002] With the development of modern architectural aesthetics, there are more and more buildings with complex curved shapes. Ultra-large hyperbolic unitized glass curtain walls are widely used because they can create smooth and dynamic building facades. These curtain wall units are usually characterized by their large size, complex shape, and high installation precision requirements.

[0003] Currently, Chinese patent application number CN202310558632.9 discloses a BIM-based construction method for hyperboloid unitized glass curtain walls in high-rise buildings. The steps are as follows: Step 1. Construct a 3D model of the hyperboloid unitized curtain wall using BIM technology; Step 2. Based on the optimized and confirmed 3D model, use BIM technology to output parameter tables for factory prefabrication; Step 3. Use a 3D laser scanner to measure, lay out, and position the model; Step 4. Perform 3D animation simulation of the entire unitized curtain wall hoisting construction process and record technical parameters; Step 5. Demonstrate the hoisting process of different parts through animation simulation; Step 6. Address the characteristics and difficulties of hyperboloid glass curtain walls; Step 7. Continuously summarize experience based on actual construction, dynamically adjust, and promote the technology.

[0004] However, existing simulation methods focus on macroscopic hoisting animation demonstrations and experience summaries, lacking real-time calculation and early warning of unit center of gravity stability and load dynamic changes during hoisting. They also do not involve specific and in-depth simulation verification of unit installation micro-stroke adjustment, complex handover relationships between adjacent units, and the dismantling process of temporary back-attached steel frames. Furthermore, they have not formed a mechanism for closed-loop feedback and dynamic optimization of the simulation model based on on-site measured data, resulting in limited simulation accuracy and precision in guiding actual construction.

[0007] Preferably, in step S1, the unit-backed steel frame is defined in the model as a detachable temporary auxiliary structure, whose geometric and physical properties are defined separately, and is used as a special lifting tool and transfer support during the hoisting stage, and needs to be removed after installation.

[0008] Preferably, the dynamic simulation of the hoisting path in step S2 specifically includes: Define the key nodes and path curves of the hoisting path; During the simulation, based on the physical properties of the model, the changes in the unit's center of gravity caused by the lifting gear's movement and rope swing are calculated and monitored in real time to ensure that the center of gravity remains within a stable range. The system's real-time collision detection function is enabled to provide early warnings about the minimum distance between curtain wall units, hoisting equipment, and the main structure, and to highlight any potential interference.

[0009] Preferably, the installation accuracy and stroke simulation in step S3 also includes the simulation of the connection relationship between adjacent curtain wall units, specifically including: simulating the relative movement of adjacent curtain wall unit panels during the installation process, analyzing the width change and coplanarity of their joints, and ensuring that all curtain wall units form a smooth and continuous hyperboloid after installation.

[0010] Preferably, the method further includes the following step between step S3 and step S4: S3a: Structural mechanical performance verification stage: Based on the material properties in the BIM model, finite element analysis is performed on the installed curtain wall units and their connection nodes to simulate the deformation and stress distribution under wind load, self-weight and temperature load, and to verify their structural safety.

[0011] Preferably, the BIM model described in step S1 also incorporates an environmental model of the construction site, including surrounding buildings, temporary facilities, and construction machinery.

[0014] Preferably, the visualization animation described in step S5 is displayed and interacted with through a visualization interface. This interface can display the hoisting, installation and dismantling process step by step and from multiple angles, and allows users to pause, zoom and view the simulation data of key nodes for the purpose of explaining the construction plan and training personnel.

[0015] Preferably, the curtain wall unit has a spatial hyperboloid shape, a maximum projected area of ​​not less than 41 square meters, and a single unit weight of not less than 9.8 tons.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention integrates a high-precision parametric model with a dynamic simulation algorithm to achieve dynamic simulation of the entire hoisting process of ultra-large hyperbolic units. This method can not only track and visualize the center of gravity trajectory and load changes of the curtain wall unit in real time and provide early warning of instability risks, but also accurately identify potential interference points with the main structure and construction environment in the hoisting path based on a continuous collision detection algorithm. It exposes and resolves all possible dynamic risks during construction, thereby upgrading construction safety control from passive response to proactive pre-control and improving construction safety and reliability.

[0018] This invention achieves micro-travel virtual simulation of the curtain wall unit installation process by predefining multi-dimensional adjustment parameters of unit mounting brackets in a high-precision BIM model. This system not only ensures that each unit is accurately positioned to the three-dimensional design coordinates on a macroscopic level, avoiding interference with the main structure, but also simulates and verifies the connection relationship between adjacent hyperbolic unit panels at a microscopic level, accurately analyzing the changes in joint width and coplanarity. This ensures that all units can form the smooth and continuous curved surface required by the design after installation in a virtual environment. At the same time, the integrated structural mechanical performance verification further ensures the structural safety after installation from a mechanical perspective, achieving a unified guarantee of geometric accuracy and structural safety.

[0019] This invention introduces a three-dimensional scanning-based on-site data feedback and model adaptive update mechanism to construct an intelligent system capable of self-learning and continuous optimization. This mechanism can dynamically correct the installation simulation benchmark of subsequent units by utilizing the deviation analysis results between the actual data of the installed units and the BIM model. This allows the simulation prediction capability to continuously approach the real construction conditions as the project progresses, improving the scientific nature and guidance accuracy of subsequent construction plans. Furthermore, it forms a digital decision-making closed loop that runs through the entire project, significantly improving the overall management efficiency and first-time success rate of large and complex projects.

[0022] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0023] Please see Figures 1 to 6 This invention provides a 3D simulation method for the construction of ultra-large hyperbolic unitized glass curtain walls. This method is based on building information modeling (BIM) technology and includes the following steps: S1. Parametric BIM Model Construction Phase: Based on the design drawings, create an integrated BIM 3D model including the main structure 1, curtain wall unit 2 (extra-large hyperbolic unitized glass), unit-backed steel frame 3, hoisting equipment 4, and connecting components 5. The model should reach a LOD 400 (component fabrication drawing level) level of detail. The hyperbolic panels and their frame profiles, unit brackets, connecting lugs of the unit-backed steel frame, high-strength bolts, etc. of curtain wall unit 2 should all be modeled according to the actual product parameters. This curtain wall unit has a spatial hyperbolic surface shape with a maximum projected area of ​​not less than 41 square meters and a single piece weight of not less than 9.8 tons. The unit-backed steel frame 3 is defined in the model as a detachable temporary auxiliary structure, and its geometric and physical properties are defined separately for use as a special hoisting tool and transfer support during the hoisting phase.

[0024] S2. Dynamic simulation stage of hoisting process: Based on the BIM 3D model, the hoisting path of curtain wall unit 2 from the lifting point to the installation position is dynamically simulated. This simulation specifically includes: defining the key nodes and path curves of the hoisting path; during the simulation, based on the physical properties of the model, the load changes of the hoisting system and the trajectory of the center of gravity of curtain wall unit 2 are calculated and visualized in real time to ensure that the center of gravity is always in a stable range; at the same time, the real-time collision detection function of the system is enabled, and the continuous collision detection (CCD) algorithm is adopted to provide early warning of the minimum distance between curtain wall unit 2, hoisting equipment 4 and main structure 1, and to highlight possible interference.

[0025] S3. Installation Accuracy and Stroke Simulation Stage: In the BIM 3D model, the curtain wall unit 2 is simulated for micro-stroke installation via unit brackets and the connecting component 5 of the main structure 1. Through parameterized constraints, the movement and rotation of the unit in 3D space are visually displayed. This simulation analyzes the allowable stroke range of the brackets in the three-dimensional directions of up / down, front / back, and left / right. Virtual adjustment ensures that the curtain wall unit 2 can be accurately positioned to the design coordinates without interfering with the main structure 1. This stage also includes the simulation of the connection relationship between adjacent curtain wall units 2. By analyzing the width variation and coplanarity of the joint, it is ensured that all units can form a smooth and continuous hyperboloid after installation.

[0026] S3a, Structural Mechanical Performance Verification Stage: Using BIM-FEM integrated analysis technology, the finite element analysis software is imported through an intermediate data format (such as IFC) or directly using the analysis module built into the BIM software to perform finite element analysis on the installed curtain wall unit 2 and its connection nodes; the deformation and stress distribution under wind load, self-weight and temperature load are simulated to verify its structural safety, and the stress level of the unit brackets, the shear force of the connecting bolts and the deflection of the glass panel are checked in particular.

[0027] S4. Unit Backing Steel Frame Removal Simulation Stage: After the simulated curtain wall unit 2 is installed and fixed, the removal process of the unit backing steel frame 3 is simulated. This simulation verifies the feasibility of the removal operation space and tool path, ensuring that the unit backing steel frame 3 can be dismantled smoothly and safely without damaging the installed curtain wall unit 2 and the main structure 1.

[0028] S5. Construction Interaction and Output Stage: Generate and output construction guidance documents and visualization animations based on simulation results; the construction guidance documents include, but are not limited to: hoisting sequence table optimized based on simulation data, allowable values ​​for installation positioning deviation of curtain wall unit 2, and dismantling operation instructions for unit back steel frame 3. The visualization animation displays an interactive BIM view through an interactive interface. Construction personnel can load the view on a tablet computer, allowing them to view the process step by step and from multiple angles, and can pause, zoom, and view simulation data of key nodes for construction scheme briefing and personnel training.

[0029] S6. Construction Process Feedback and Model Update Phase: During construction, 3D scanning technology is used to acquire the actual location point cloud data of the installed units. This data is then compared with the BIM design model in 3D, generating a color difference map to visually display the deviations. Based on the deviation analysis results, the installation position parameters of subsequent curtain wall unit 2 in the BIM model are dynamically corrected and optimized to align the virtual model with the physical building. All subsequent installation simulations will be based on the updated benchmark, thereby achieving feedforward control and ensuring that the final architectural outcome matches the design intent. Figure 1 This leads to a closed-loop control system of "simulation-construction-feedback-optimization".

[0030] In the above, the 3D simulation method forms a complete closed-loop workflow through steps S1 to S6; specifically, as follows... Figure 1As shown in the overall flowchart, after completing step S5 and outputting the construction guidance document and visualization animation, the actual construction phase of "starting physical construction" begins. During the physical construction process, on-site technicians need to execute step S6, namely the "construction process feedback and model update stage". In this stage, the actual point cloud data of the installed curtain wall units (i.e., "feedback data") is obtained through 3D scanning and compared with the BIM design model. The deviation analysis results obtained will be used as key "feedback data" to dynamically correct and optimize the BIM model and simulation parameters of the subsequent uninstalled units, thereby realizing the intelligent construction closed loop of "simulation-construction-feedback-optimization".

[0031] In step S1, the BIM model is generated through parametric modeling using Rhino and Grasshopper software. The model has a resolution of LOD 400 and integrates the environmental model of the construction site. The objects in the model are assigned three-dimensional adjustment ranges for mass, material, center of gravity, unit brackets, and removability markings for the attached steel frame.

[0032] The objects in the model are given key physical and behavioral attributes, including but not limited to: the mass, material, and center of gravity of the components; the degree of freedom constraints of moving components such as hooks and shackles; the three-dimensional adjustment range of the unit hangers (e.g., ±30mm in the X direction, ±25mm in the Y direction, and ±20mm in the Z direction); and the removability markings of the back steel frame.

[0033] The hoisting path is defined by a series of keyframes. The simulation software generates a smooth hoisting animation through interpolation algorithms. The path planning needs to take into account the working radius, lifting height and slewing angle of the tower crane. During the simulation, the system’s built-in lightweight dynamics engine calculates the swing of the hoisting rope and the changes in the unit’s attitude in the air. It also updates and visualizes the unit’s center of gravity coordinates and load coefficient in real time. When the calculated center of gravity offset exceeds the preset safety threshold, the system issues a warning.

[0034] Example 1: Taking the super-large hyperbolic glass curtain wall project of a building as the background, a 3D simulation was carried out on the curtain wall unit numbered A-05 before construction. The projected area of ​​the curtain wall unit is 42 square meters and the weight is 9.9 tons.

[0035] First, the BIM model is generated in batches in Rhino software using the Grasshopper plugin by inputting spatial curve parameters and driving algorithm calculations. This model not only accurately expresses the hyperbolic shape of the unit, but also achieves a level of detail of LOD 400 for its profiles, unit brackets, and backing steel frames. Furthermore, the model is endowed with key physical and behavioral attributes: the system automatically calculates the mass and center of gravity coordinates of the unit, defines a three-dimensional adjustment range of ±30mm in the X direction, ±25mm in the Y direction, and ±20mm in the Z direction for the unit brackets, and marks the backing steel frames as "removable" temporary structures.

[0036] Next, step S1 is executed: the above BIM model is imported into dynamic simulation software (such as Navisworks). When simulating the hoisting of the curtain wall unit along the predetermined path, the system calculates in real time, based on the physical properties of the model, that the unit's center of gravity shifts due to inertia when turning, and the trajectory exceeds the stability threshold, and issues a warning. At the same time, the continuous collision detection algorithm warns that at the end of the path, the minimum distance between a corner of the unit's back steel frame and an embedded part is only 60mm. Based on this simulation result, the construction team optimizes the hoisting speed control strategy and fine-tunes the hoisting point position of the unit when it leaves the factory, avoiding potential risks.

[0037] Then, step S3 is executed: installation accuracy simulation is performed. The simulation shows that in the Z direction (height), the hanging bracket needs to be adjusted upward by 12mm to reach the design coordinates. This value is within the allowable stroke range. At the same time, the joint between A-05 and the adjacent A-04 and A-06 units is simulated to confirm that the joint width can be controlled within the design requirement of 18±2mm and the surface transition is smooth.

[0038] Subsequently, step S3a was executed: the installed BIM model was imported into the finite element analysis software in IFC format. After applying the combined working conditions of wind load and self-weight, the analysis results showed that the maximum stress of the element bracket was 125MPa, which was lower than the yield strength of Q235 steel. The shear force of the connecting bolts was also much lower than the design value, verifying the structural safety.

[0039] Finally, steps S4 and S5 were executed: the rotation path of the non-interference dismantling of the attached steel frame was successfully simulated, all simulation results were integrated, and a special hoisting operation instruction and briefing animation for unit A-05 were generated, clearly marking the key adjustment dimensions and risk points.

[0040] Example 2: Based on Example 1, this example further demonstrates the value of closed-loop control in practical engineering.

[0041] After the actual installation of unit A-05 was completed, the project team performed step S6: scanned the installed unit A-05 with a 3D scanner to obtain high-precision point cloud data; after comparing the point cloud with the original BIM design model in 3D, a deviation color difference map was generated. The analysis revealed that the lower left corner of the unit had an average negative deviation of about 10mm in the X direction (front and back) (i.e., an inward offset).

[0042] This systematic deviation may have originated from construction errors in the main structure. To avoid the accumulation of this error in subsequent units, the technicians made a uniform +10mm pre-offset correction in the X direction for the mounting bracket connection points of all subsequent curtain wall units to be installed (starting from A-06) in the BIM model.

[0043] Based on this updated "benchmark model", the team re-performed simulations from S2 to S5 on unit A-06. The new installation stroke simulation showed that after pre-offset, the adjustment of the brackets of unit A-06 in all directions was within the ideal range, and the joint quality prediction with unit A-05 was better. This effectively improved the installation accuracy and efficiency of the entire curtain wall project and ensured that the final building surface was highly consistent with the design intent.

[0044] In addition, the present invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the above-mentioned 3D simulation method for the construction of ultra-large hyperbolic unitized glass curtain walls.
