Embodiment 1

[0039] Such as figure 2 As shown, a method for monitoring the verticality of the tower crane is exemplified. At present, the conventional method for monitoring the verticality of the tower crane requires professional surveyors to use special measuring instruments, such as total stations, theodolites and other instruments for monitoring operations. This method of tower crane verticality monitoring is not flexible, the monitoring operation is inconvenient, the monitoring data cannot be obtained in time, and the monitoring personnel are fixed, which is not conducive to the safety management of the tower crane, and often easily leads to the occurrence of tower crane safety accidents. In this context, a method for monitoring the verticality of the tower crane is a fundamental problem that needs to be solved.

[0040] The method for monitoring verticality of the tower crane specifically includes the following steps:

[0041] (1) After the installation of the tower crane is complet...

Embodiment 2

[0050] Such as image 3 As shown, a method for construction survey positioning setting out is provided, which specifically includes the following steps:

[0051] (1) After the construction drawings are completed, create a BIM model with LOD400 precision level according to the general construction plan drawings. The BIM model must meet the requirements of LOD400 precision level and meet and reflect the information of the construction drawings. The software used to create the model is not limited to Autodesk Revit software and its series of auxiliary software products. According to the requirements of modeling convenience and flexibility, various forms of BIM software can be used.

[0052] (2) Before the construction, use the 3D holographic scanning technology, use the UAV 3D laser scanner to scan the construction site, and collect the 3D point cloud information of the construction site. The 3D point cloud data information of the construction site collected by scanning is saved...

Embodiment 3

[0063] Such as Figure 4 As shown, a measurement and positioning method for the installation of special-shaped steel structural members with variable spatial angles is provided, which specifically includes the following steps:

[0064] (1) After the construction drawings are completed, a BIM model of LOD400 precision level is created according to the steel structure drawings. The BIM model must meet the requirements of LOD400 precision level, meet and reflect the model of the construction drawing information. The software used to create the model is not limited to Tekla software and its series of auxiliary software products. According to the requirements of modeling convenience and flexibility, various forms of BIM software can be used.

[0065] (2) Before the installation and construction of the steel structure components, use the 3D holographic scanning technology to scan the construction site with the 3D laser scanner of the UAV, and collect the 3D point cloud information o...

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...
