AI Technical Summary

Technical Problem

In large-span, irregularly shaped buildings, traditional existing technologies are difficult to use for simple connection techniques, especially when the exterior is constructed with steel structures to form irregular curved surfaces, making it difficult to connect the glass curtain wall to the steel structure, resulting in installation difficulties.

Method used

By using BIM-based 3D modeling and virtual assembly, the outer contour steel structure is divided into multiple unit planes. Target plates are installed and their positions are determined to guide the production and installation of curtain wall accessories. The position and angle of the curtain wall glass are adjusted using reference bases and glass assemblies, and then installed in conjunction with the keel frame.

Benefits of technology

It enables precise positioning and installation of irregularly shaped curved glass curtain walls, reduces on-site adjustment workload, saves construction time and costs, and extends the service life of buildings.

Abstract

The application provides a large-span special-shaped curved surface curtain wall installation method based on BIM, three-dimensional modeling and virtual assembly are performed on the outer contour steel structure to form a complete skeleton structure; the outer contour steel structure is divided into a plurality of unit planes in a virtual space; a plurality of target plates are installed on the unit planes, and the positions of the target plates are measured by using a measuring device; the production and manufacturing of curtain wall fittings are guided according to the deformation amount of the outer contour steel structure, and the curtain wall is installed by using the curtain wall fittings; the positions of the target plates are measured again and recorded; the above steps are repeated to install curtain wall glasses of another unit plane, until all the outer side surface curtain wall glasses of the outer contour steel structure are installed, and the problem of difficult installation and positioning of the special-shaped curved surface glass curtain wall is solved.
