Steel structure and curtain wall intelligent monitoring and maintenance system based on BIM

Abstract

The invention provides a steel structure and curtain wall intelligent monitoring and maintenance system based on BIM, and relates to the technical field of building information simulation. The systemcomprises a stress-strain monitoring system, a visual monitoring system, a data processing module, a calculation and analysis module, an early warning information publishing platform and a model optimization system. The stress-strain monitoring system and the visual monitoring system are installed, the two sets of monitoring systems are integrated to monitor a main body structure in real time, andactual deformation of a monitoring point is determined according to the average value of the two sets of data. The calculation and analysis module further calculates, simulates and analyzes the deformation of a steel keel through the deformation data of the main body steel structure, so that the stress state of the curtain wall glass is obtained, the safety state of the glass is expressed in a BIM model through different colors, and a dangerous source is synchronously notified to engineering technicians. According to the steel structure and curtain wall intelligent monitoring and maintenancesystem based on BIM, real-time safety monitoring of the curtain wall glass is realized, the accuracy of structural deformation monitoring is improved through synchronous analysis of two sets of monitoring data, real-time intelligent early warning is realized, and potential safety hazards are eliminated in advance.

Description

technical field [0001] The invention relates to a BIM-based steel structure and curtain wall intelligent monitoring and maintenance system, which belongs to the technical field of building information simulation technology and steel structure and curtain wall engineering safety monitoring application. Background technique [0002] BIM is the abbreviation of Building Information Modeling, that is, building information model, which integrates the geometric information and non-geometric information of the building structure into a three-dimensional visualized digital model for the application of the whole life cycle of the building.

Problems solved by technology

[0003] Steel structures and curtain wall projects are now more and more widely used, but glass self-explosion and cracking of curtain walls have always been unavoidable failures in the process of building use, especially in large buildings, where there are a large number of curtain wall glass, and glass self-explosion and cracking cannot be predicted. Bring security risks and affect the normal use of users

[0004] The reasons for the self-explosion of glass are mainly divided into three situations: (1) impurity in the glass causes self-explosion; (2) installation accuracy control problems, such as poor control of component processing accuracy, excessive deformation of structural installation, etc.; (3) during use, because Deformation of the main structure causes stress concentration and cracking of the glass
