[0002] With the rapid development of urban construction, in order to improve the aesthetics of urban buildings, curtain walls are usually used to decorate the exterior walls of buildings. Curtain walls use a variety of strong, light and beautiful building materials to replace the traditional brick or window-wall combination exterior wall construction method. It is an exterior wall construction method that surrounds the main structure of the building to make the entire building beautiful, functional and safe.

[0003] In recent years, the exterior shapes of curtain walls of large sports venues and super-large space buildings have shown a trend of diversification. The inverted cone twisted surface aluminum plate curtain wall is increasingly used in the exterior wall decoration of large sports venues because it can highlight the agility and smooth curve elements of the building. However, the irregular shape of the inverted cone twisted surface aluminum plate curtain wall makes its construction more complicated and difficult, especially in the installation of the keel. The keel of the inverted cone twisted surface aluminum plate curtain wall has a twisted curvature, which further increases the difficulty of manufacturing and installing the keel. The main keel and the secondary keel are difficult to install and position. Due to the existence and accumulation of keel manufacturing errors and installation errors, it is easy to cause the keel to not match the position of the building embedded parts, seriously affecting the installation efficiency and construction period of the curtain wall.

[0004] In addition, the aluminum plate of the existing inverted cone twisted surface aluminum plate curtain wall is assembled into a curved surface by flat aluminum plate units, which easily forms a drop at the joint of two adjacent aluminum plate units.
