The Combined Application of Cold Bending Technology and BIM Design of Unit Curtain Wall——Taking Chongqing Fashion Culture City as an Example
With the support of digital technology,modem architecture is developing in two directions:ultra-high,large volume and complex shape.Chongqing Fashion Culture City is the only super-high-rise building under construction in Jie Fangbei,with a total height of about 300m,and the outer skin of the building is composed of about 5,000 special-shaped curved surface units.The principle of cold bending is to make use of the elastic and bendable properties of glass and aluminum profiles,and to achieve the final effect of fitting the surface of curtain wall through artificial and reasonable bending deformation during installation.However,for buildings with large volume and different shapes,BIM technology is needed to systematize the data of the unit curtain wall.The accurate data calculated by BIM can analyze the cold bending range of the unit curtain wall plate required by the design review,and guide the positioning and installation of the unit curtain wall plate to avoid the step difference of the curtain wall.Taking Chongqing Fashion Cultural City as an example,this paper discusses the combined application of cold bending technology of unit curtain wall and BIM technology,which reflects the strong advantages of this application in the design,blanking and construction of unit curtain wall,with a view to providing reference for improving the efficiency of current unit curtain wall construction design.
