Description

Technical Field

[0001] The present invention belongs to the field of prefabricated buildings, and specifically relates to a quality detection system and method for prefabricated building components based on BIM technology. Background Art

[0002] With the rapid development of the construction industry, especially the popularization and application of prefabricated buildings, the quality inspection and structural health monitoring of building components have become particularly important. However, traditional building component inspection methods mainly rely on manual inspection and empirical judgment, which have the disadvantages of low efficiency, insufficient accuracy, and difficulty in fully covering all key parts. Especially in complex building structures, the limitations of sensor technology and data processing methods make it difficult to achieve comprehensive monitoring and analysis of the stress, deformation and connection parts of building components.

[0003] Traditional building quality inspections typically rely on simple visual inspections or localized experimental testing. These methods not only fail to dynamically monitor building components throughout their lifecycle, but also struggle to accurately identify potential structural damage and connection anomalies, which can easily lead to safety hazards. Furthermore, traditional inspection methods lack a systematic analysis of the stress patterns and damage conditions of building components, making it difficult to provide a scientific basis for the health of building structures, which in turn impacts the safety and service life of buildings.

[0004] In recent years, with the development of BIM (Building Information Modeling) technology, its application in building design, construction, and operation and maintenance has gradually increased. However, existing BIM technology mainly focuses on information integration and management during the building design and construction phases, and rarely involves real-time inspection and analysis of building component quality. Especially in prefabricated buildings, due to the standardized and modular characteristics of components, traditional inspection methods are difficult to meet the needs of efficient and accurate component quality inspection.

[0005] In order to solve the problems raised by this background technology, the present application designs a quality inspection system and method for prefabricated building components based on BIM technology. Summary of the Invention

[0006] In response to the deficiencies in the prior art, the present invention proposes a system and method for quality inspection of prefabricated building components based on BIM technology. The present invention distributes position weights based on the historical stress damage and construction strength conditions at each location of the corresponding building, performs connection anomaly analysis at each location based on the stress conditions at each location and the deformation of the building components in the corresponding stress direction, and performs component quality analysis based on the deformation conditions at each location, the connection anomaly analysis results, and the position weight distribution results. By analyzing historical data, the stress patterns, potential damage, and impact weights of building components at different locations can be identified, thereby comprehensively monitoring the health status of the building structure. Real-time deformation and connection anomaly detection can promptly identify structural safety hazards, prevent potential structural failures, and ensure the safety of the building.

[0052] S11. Acquire the dimensional data of each position of the assembly component to be inspected, and simultaneously acquire the dimensional data of each position of the standard assembly part, and construct a BIM model of the assembly component using BIM model construction software. Exemplarily, the specific steps are as follows: 3D modeling: using BIM software (such as Revit, ArchiCAD, etc.) to create a 3D model of the assembled component; information entry: entering detailed information of the component into the model, including size, material, production batch, etc.; parameter setting: setting key parameters of the component to ensure that the model is consistent with the actual component; and storing the acquired BIM model in a corresponding storage module;

[0055] S2. Construct a weight distribution model to distribute location weights based on the historical stress damage and construction strength of each location of the corresponding building;

[0056] In a specific embodiment, the weight allocation model includes the following specific steps:

[0057] S21, obtaining real-time force data of each docking position after the corresponding building assembly component is assembled and damage deformation data of each docking position;

[0058] S22. Perform deformation anomaly analysis of each docking position based on the damage deformation data of each docking position, wherein the calculation formula for deformation anomaly analysis of docking positions is: , where N is the number of monitoring points at the docking position, di is the deformation of the i-th monitoring point at the docking position, and dim is the deformation safety value of the i-th monitoring point at the docking position. In this step, the deformation abnormality of the docking position is accurately analyzed by analyzing the deformation of each point at the docking position. For example, the deformation safety value corresponds to the maximum value of the deformation safety of the corresponding point;

[0059] In one of the specific examples, the docking scenario is: the building components are bridge docking, and there are five monitoring points corresponding to the docking location;

[0060] The real-time deformation of monitoring point M1 is 1.2 mm, and the safety value is 1.0 mm;

[0064] The real-time deformation of monitoring point M5 is 1.6 mm, and the safety value is 1.4 mm;

[0065] In this example, the calculated deformation anomaly of the docking position is: (1.2+0.8+1.5 / 1.3+0.9+1.6 / 1.4) / 5=1.039;

[0066] S23. Based on the deformation anomaly analysis results of the docking position during the installation period and the force data of the docking position, analyze the connection anomaly of the corresponding docking position, wherein the calculation formula for the connection anomaly of the docking position is: , where T is the installation period, Xbt is the deformation anomaly analysis result of the docking position at time t of the installation period, dt is the time integral, Ft is the force data at time t of the installation period, and Fz is the force data set for the docking position during design. This step analyzes the connection anomaly of the docking position by analyzing the relationship between force and deformation anomaly;

[0067] S24. Obtain the connection anomaly corresponding to the docking position and the construction strength data of the current building component at the corresponding connection position, and assign a position weight based on the connection anomaly corresponding to the docking position and the construction strength data of the current building component at the corresponding connection position.

The importance weight of each location is evaluated based on the severity of the damage and the construction strength of the corresponding location. This improves the rationality of the weight distribution of each location, assigns more weight to the quality inspection of key locations, and effectively improves the safety of building component inspection.

[0069] S3. Analyze the connection anomalies at each location based on the stress conditions at each location and the deformation of the building components in the corresponding stress direction;

[0072] S32. Analyze the abnormal connection at the corresponding position based on the image data and internal defect data of the docking position. The analysis formula for the abnormal connection at the corresponding docking position is: , where G is the number of defects, vg is the volume of the g-th defect, vc is the volume of the connection position, Dr is the distance standard value, and Dg is the average distance from the i-th defect to the butt contact surface.

[0073] In this step, the defects at the docking position are quantitatively analyzed, and the impact of the defects on the docking position is comprehensively judged based on the size and corresponding location of the defects;

In this step, the overall connection quality of the component is analyzed by comprehensively considering the shape change of the corresponding component, the position weight of each docking position, and the connection abnormality of the docking position;

[0078] For example, the connection anomaly ratio weight represents the impact of the connection anomaly on the component quality, and the image ratio weight represents the impact of the image difference on the component quality. In a specific embodiment, the connection anomaly ratio weight and the image ratio weight are 0.82 and 0.18 respectively.

[0079] S5. Output component quality based on component quality analysis results;

[0083] The advantages of this embodiment over the prior art are as follows: position weights are allocated based on the historical stress damage conditions and construction strength conditions at each location of the corresponding building; connection anomaly analysis is performed at each location based on the stress conditions at each location and the deformation conditions of the building components in the corresponding stress direction; component quality analysis is performed based on the deformation conditions at each location, the connection anomaly analysis results, and the position weight allocation results.
