Abstract
Chengdu Xinhua Star Project is designed by integrating insert unit elements with aluminum panel boxed eave. Because the unit elements are installed between the upper and lower floors, the traditional vertical lifting process cannot meet the installation requirements. Therefore, this project uses the mobile mechanical arm developed by our company for installing unit element indoors. The mobile mechanical arm is 3045×1699×1320mm with the rated load of 600kg, the self-weight of 1750kg and the counterweight of 600kg. It can be disassembled or separate transportation and has the functions of free displacement, three-dimensional adjustment and absorption and grabbing. During construction on site, first of all, the grid lines, finished surface line, and bottom and top locating lines of the adapting piece of the unit element are clearly marked and set out on the main structure. According to the geometric dimension of the mechanical arm and the locating line of the curtain wall, the movement locating line of the mechanical arm is drawn. Then, the mechanical arm is operated indoors for installation. The indoor installation process of curtain wall explored by this project provides a new idea for the construction of the unitized curtain wall of ultra-high rise buildings. It can alleviate the construction difficulty of the unitized curtain wall, reduce the safety risks and measure costs of outdoor installation of the unitized curtain wall of ultra-high rise buildings, thus being a new type of curtain wall construction process that is worthy of promotion and application.

Summary
Chengdu Xinhua Star Project is located in Jinjiang District, Chengdu. With the “mountain of books” as the skeleton, decorating by “bamboo slips” and forming an image of “lighthouse” on the whole, this project symbolizes “heights of culture, a beacon of industry”. This research explores the indoor installation technique for unitized curtain walls in super high-rise buildings, decrease the difficulty for work by developing the considerate indoor installation technique and reduce the safety risks and measure costs of outdoor installation of curtain walls for super high-rise buildings, as well as the influence of constraints by the main structure. 2. Research Status and Significance of Applying Mobile Mechanical Arm in the Installation of Curtain Walls. The unitized curtain wall construction of super high-rise buildings faces very high safety risks [2]. Because it is difficult to lift and install unitized curtain walls in the existing super high-rise buildings and the installation is conducted outdoors, there are too many safety hazards [3], so the existing installation scheme must be innovated. The research proposes an indoor installation technique for unitized curtain walls in super high rise buildings, which can meet the need for Xinhua Star Project, and
