Digitization of Building curtain wall

Digital technology is an information sharing platform, including owners, architectural design institutes, modern curtain wall design units, processing units, curtain wall construction units, post-maintenance units, acceptance units, etc. With the project as the core, we build a collaboration platform through intelligent and collaborative technology. The collaboration platform is built in different levels, and each level is divided into domain layer, interaction layer, core layer and resource layer. Through setting permissions, different users have different permissions, so as to realize the sharing and information security of the platform. Digital technology is the basis of digital information models to curtain wall skin model as the carrier, to digital technology parameters, the model created based on the main structure model, and considering the main structure of the error, and to compare the theoretical model and actual working condition, and to modify the model, to obtain the final construction BIM model.

The relationship between the new part and the old part should be considered in the modeling of the reconstruction building. If the old building has a BIM model, the model of office glass curtain should be closed with the old building. If necessary, the existing model should be digitized through 3D scanning for comparison and collision detection with the new model. Through the collision detection of the existing old building model of National Convention and Exhibition Center, the new building’s eaves and other parts were modified to avoid the structural collision in the construction process. The architectural model is only the three-dimensional embodiment of the building. The real realization of digital and information application requires the parameterized information given to the architectural model, and the parameterized design of the model is the goal of BIM technology application. Model para-materialization is part of the 3 d model giving different attributes, such as the parameters of the glass plate, which can contain information including size information, materials, attached to the frame information, such as parametric information, according to the different project and different depth and different model of point support curtain wall.

At present, the digital application is in the process of quantitative change. Through continuous attempts in some projects, we have accumulated more and more experience. With the introduction of national encouraging policies and the release of norms and standards, the digital architecture will embrace qualitative change, realize the popularization of the industry, and provide a strong guarantee for the realization of innovative architecture in terms of hidden frame glass curtain wall and fine management.
