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 and the 3D laser scanner of the UAV to scan the construction site and collect the 3D point cloud information of ...

Abstract

The invention discloses a method for monitoring the deformation of a scaffold outside construction, which comprises the steps of: creating a BIM model of the scaffold according to the scaffold installation drawing; performing holographic three-dimensional laser scanning on the installed scaffold, collecting and storing the three-dimensional point cloud data of the scaffold; The point cloud data processing software processes the 3D point cloud data to obtain a complete scaffold point cloud model; fits and analyzes the scaffold point cloud model and the BIM model to obtain the deviation data of the two models. The invention solves the problem that measuring instruments such as a total station need two or more people to operate to conduct the lead measurement of the measurement points, and multiple lead measurements will cause certain measurement errors. In addition, the use of three-dimensional laser scanners for scaffolding data collection operations solves the shortcomings of using total stations and other measuring instruments for monitoring, which may cause inability to monitor due to a large amount of field work, unfavorable weather and night conditions.

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...
