The application belongs to the technical field of fabricated
building process, and particularly relates to a
curtain wall large
keel fabricated installation construction process based on BIM technology and 3D scanning technology, and the specific steps are as follows: 3D scanning technology is used to perform three-dimensional scanning on the construction site, and collect and input various
data information of the construction site; BIM technology is combined to model the project, and material shape data, size information and part matching data are extracted; after the data is extracted, the
keel components of different shapes and sizes are grouped and numbered one by one, and then the
curtain wall large
keel is produced in the factory; after the keel component is processed, it is directly transported to the
processing site and installed according to the number, and the keel and the base are screwed during installation, so that the installation is completed, the application can simplify the installation steps, does not need to repeatedly adjust and
cut the keel, improves the installation speed, and further shortens the construction period, while ensuring the
engineering quality, and reduces the management cost.
