The curtain wall facade of the Shanghai central building is divided into 13 systems: the PG1 type single-story cable mesh glass curtain wall system located at the commercial entrance of the east facade; PG2 type large-span thin plate separator point supported glass curtain wall located in the north commercial area; PG3-2 type large-span steel and aluminum junction point support glass curtain wall located in the meeting hall of the west facade; PG3-1 type large-span single-layer cable mesh glass curtain wall system located in the banquet hall on the west facade; PS type integral unit hanging open back bolt stone curtain wall located in the north and east-west water wall; PR Type Gold muscular glass curtain wall located on the roof, Waterproof system of internal vertical locking edge aluminum magnesium manganese plate roof, PR type golden muscle glass curtain wall located in the wall and ceiling part, Internal black PVDF aluminum board waterproof system; VIP Hall (bar) glass rib point support glass curtain wall system, located at the fifth floor sightseeing and leisure platform on the west side; B10 type steel and aluminum combined hidden frame glass curtain wall system located in the west conference hall; Hidden frame glass and open back bolt stone base curtain wall located on the first floor of the south side; J type large-span cable pipe combination glass curtain wall of rough frame located in the south interior; Glass canopy system located on the south and north sides; Hidden frame glass, open stone curtain wall and a large number of glass panels are located in the east and west sunken squares.
The epidermis of the curtain wall of Shanghai central building is very complex, which not only involves ordinary single curved surface, but also has a regular space distortion surface. Each curtain wall system has its own different spatial geometric shape. In particular, with the PR curtain wall, the geometric epidermis is a nonlinear surface that cannot simply express its geometric information with mathematical functions. The traditional drawing software is impossible to accurately express the curtain wall partition, structure and relative relationship with the main structure. In addition, there are many curtain wall systems, and 13 curtain wall systems are interconnected or multiple connected, resulting in many system junctions, and most of the junctions are different faces of different geometric space shapes. Therefore, how to perfectly realize the design intention of the architect, ensure the accurate presentation of the building appearance, and accurately realize the handover of the unitized glazing system is the difficult points and key points to be solved.
