Description

Technical Field

[0001] The present invention belongs to the field of prefabricated buildings, and specifically relates to a quality inspection 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 of building components and the structural health monitoring have become particularly important. However, the 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 comprehensively 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 forces, deformations, and connection parts of building components. In traditional building quality inspection, simple visual inspection or local experimental testing methods are usually adopted. This method not only fails to achieve dynamic monitoring of the entire life cycle of building components, but also is difficult to accurately identify potential structural damage and connection abnormalities, which easily leads to safety hazards. In addition, traditional inspection methods lack systematic analysis of the force patterns and damage conditions of building components, making it difficult to provide a scientific basis for the health status of building structures, thus affecting the safety and service life of buildings. 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, the existing BIM technology mainly focuses on information integration and management in the building design and construction stages, and rarely involves real-time inspection and analysis of the quality of building components. Especially in prefabricated buildings, due to the standardized and modular characteristics of components, traditional inspection methods are difficult to meet the requirements of efficient and accurate inspection of component quality. To solve the problems raised in this background art, the present application designs a quality inspection system and method for prefabricated building components based on BIM technology. Summary of the Invention

By analyzing historical data, the force patterns, potential damages, and influence weights on components at different positions of building components can be identified, so as to comprehensively monitor the health status of the building structure. Real-time deformation and connection abnormality detection can timely identify structural safety hazards, prevent potential structural failures, and ensure the safety of the building.

[0004] To achieve the above object, the present invention provides the following technical solutions: A method for detecting the quality of prefabricated building components based on BIM technology, which includes the following specific steps: S1.

Then, import the component quality analysis result and the judgment result into the fitting software for data fitting, and output the value-taking of the set parameters that meets the maximum judgment accuracy rate. The advantages of this embodiment compared with the prior art are: The position weights are assigned based on the historical force damage situation and construction strength situation at each position of the corresponding building. The connection abnormality at each position is analyzed based on the force situation at each position and the deformation situation of the building components in the corresponding force direction.
