Problems solved by technology

At present, in the detection and positioning of space steel structures, it is difficult to detect the intersection of steel structures with traditional detection instruments, and it is difficult to detect the installation position of special-shaped structures.
[0003] Traditional surveying and mapping is difficult to locate in three-dimensional space, and when three-dimensional surveying and mapping technology uses line laser technology in the process of measurement, its detection accuracy and speed are affected by mechanical movement and feedback systems, resulting in tedious surveying and mapping that is time-consuming, labor-intensive, and inaccurate High causes installation quality deviation, economic benefits and safety hazards

Embodiment 1

[0024] Such as Figure 1-2 Shown: .

[0025] A BIM-based 3D positioning guidance detection method, comprising the following steps:

[0026] Step 1: Establish a BIM virtual model and convert a detectable 3D data model file,

[0027] Establish a BIM virtual model in Revit in strict accordance with the design drawings, convert the established BIM virtual model into a detectable 3D data model file, and ensure that no data is lost when the Revit interface converts the 3D data model; the 3D data model is applied to 3D positioning guidance detection , is a brand-new application method that controls the accuracy of on-site actual detection through the accuracy of the 3D data model, so as to meet the requirements of controlling the installation positioning accuracy and achieve the best detection effect.

[0028] Step 2: 3D positioning guidance detection equipment erection and reality interactive inspection system,

Abstract

The invention discloses a BIM-based 3D positioning guide detection method, which comprises the steps of converting an established BIM virtual model into a detectable 3D data model file to assist in on-site detection, and controlling and improving on-site manufacturing, erection and detection precision through the BIM virtual model, and compared with a traditional method, the BIM-based 3D positioning guide detection method can realize an optimal detection effect.

Description

technical field [0001] The invention belongs to the technical field of steel structure installation in the building construction industry, and in particular relates to a BIM-based 3D positioning guidance detection method. Background technique [0002] The current high-level and rapid construction of large-scale stadium projects is of great reference significance for other projects. At present, it is difficult to detect the intersection of steel structures with traditional detection instruments in the detection and positioning of space steel structures, and it is difficult to detect the installation position of special-shaped structures. [0003] Traditional surveying and mapping is difficult to locate in three-dimensional space, and when three-dimensional surveying and mapping technology uses line laser technology in the process of measurement, its detection accuracy and speed are affected by mechanical movement and feedback systems, resulting in tedious surveying and mappin...
