Construction external scaffold deformation monitoring method

Abstract

The invention discloses a construction external scaffold deformation monitoring method. The method comprises the following steps that: the BIM model of a scaffold is established according to a scaffold installation drawing; holographic three-dimensional laser scanning is performed on a mounted scaffold, and the three-dimensional point cloud data of the scaffold are acquired; the three-dimensionalpoint cloud data are processed through point cloud data processing software, so that a complete scaffold point cloud model is obtained; and fitting and analysis are performed on the scaffold point cloud model and the BIM model, so that the deviation data of the scaffold point cloud model and the BIM model can be obtained. According to the prior art, when a total station and other measuring instruments are used, two persons or a plurality of persons are required to perform pilot testing on measurement point positions, and certain measurement errors can be caused by multiple times of pilot testing, however, with the construction external scaffold deformation monitoring method of the invention adopted, the above defects in the prior art can be eliminated. When the total station and other measuring instruments are used to perform monitoring, the workload of field operation is large, monitoring cannot be realized under conditions of adverse weather, night and the like, while, a three-dimensional laser scanner is adopted to collect scaffold data in the method of the invention, and therefore, the above problem can be solved.

Description

technical field [0001] The invention relates to the field of building engineering construction measurement, in particular to a monitoring method for the deformation of scaffolding outside construction. Background technique [0002] With the continuous advancement of construction technology, the forms of construction scaffolding are also increasing, and the installation methods of construction scaffolding are also constantly developing and changing. Especially the external scaffolding has played a great role in providing operating space and safety protection during the construction work. However, there are certain risk factors in the construction process of external scaffolding. In the process of safety management on the construction site, external scaffolding, especially external scaffolding exceeding a certain scale, should be monitored as a major source of danger, and the main method of monitoring is to measure monitor. [0003] At present, the traditional external scaff...
