Abstract

The invention provides a BIM-based steel structure deformation monitoring method. The method comprises the steps of obtaining a field point cloud model of a steel structure; comparing the on-site point cloud model with the BIM model, expressing a monitoring result including the position of the steel structure of which the deformation value exceeds a theoretical allowable deviation range, the deformation form of the steel structure and the position of the steel structure of which the theoretical deviation is greater than a preset threshold value in a chromatographic form, and feeding back the monitoring result to the site; and adopting corresponding control measures on site. The problems that a traditional structural deformation monitoring means is large in point distribution workload, incomplete in monitoring range and large in measurement result error, and an existing BIM model is disjointed with field conditions can be solved, the three-dimensional laser scanning technology and the BIM technology are combined, overall continuous monitoring of the building construction process is achieved, the overall state of a building is reflected more quickly and comprehensively, reliable guarantee is provided for deformation control in the construction process, and meanwhile social and economic benefits are improved.

Description

technical field [0001] The invention relates to a BIM-based steel structure deformation monitoring method. Background technique [0002] With the rapid development of the construction industry in recent years, modern buildings are increasingly pursuing innovative shapes, resulting in more and more complex structural forms, and the requirements for structural deformation monitoring during construction are also getting higher and higher. [0003] The conventional method used in deformation monitoring is to measure the deformation value of the key points of the target building to represent the deformation of the building. Commonly used instruments are theodolite, range finder, total station and so on. This point-to-area monitoring method can only reflect the deformation at local locations, and there are large measurement errors through manual measurement. In addition, this method has a large workload, and the layout of points is easily affected by terrain conditions, which has...
