Abstract
Due to complex shape and irregularity, projects of special-shaped buildings and venues are always limited by low construction efficiency and uncontrollable quality. The main form of the Application of Curtain Wall Prefabrication Scheme in Phoenix Mountain Sports Center is perforated aluminum panel curtain wall, which connects the stadium and gym through gradually varied curves, and creates the varied facade texture through metal panels of two colors (dark and light). The facade of the perforated aluminum panel curtain wall is streamlined, the overall shape is complex, with gradually varied and irregular shapes in horizontal and vertical directions, the aluminum panels are arranged in staggered seams, and the theoretical positions of the four corners are not coplanar. The number of aluminum panels is about 6000, and the number of assembled aluminum panels with different size is about 60,000. Conventional construction measures cannot meet the requirements of construction period and benefit. This paper aims to explore the application of prefabrication schemes in special-shaped curtain walls and provide relevant experience for other similar projects by studying the process of implementing the curtain wall prefabrication scheme in Phoenix Mountain Sports Center. A series of practices have proven that a large stadium can be constructed according to the integral hoisting scheme of sectors. Studies on how to design overall hoisting system for steel joist of large volume unit, how to install the steel joist of large volume unit, how to install non-coplanar special-shaped curtain wall and how to implement integral hoisting of metal roofing purlin may help to solve difficulties such as difficult construction, high cost and uncontrollable quality of large volume non-coplanar special-shaped curtain wall. Especially, studies on prefabrication construction techniques may help to simplify complex traditional bulk construction procedures, save time, improve work efficiency and reduce construction costs.

Summary
The façade curtain walls are overlapped and staggered, and the color texture and texture size of the metal skin gradually change with the streamline modeling of the façade. Phoenix Mountain Sports Center, a landmark composed of a stadium and a gymnasium and located in Beixing Avenue, North of Chengdu, is under construction in full swing, which may accommodate 60,000 spectators. Beixing Avenue to the west, Tianlong Road to the north, Tiange Road to the south, and Urban Green Park to the east, Phoenix Mountain Sports Center is located in Dujianian Area, Jinniu District, 4km away from Third Ring and 1km away from belt freeway, and it is an important node on the. North-South Axis of urban development of Xincheng in Northern Chengdu. Phoenix Mountain Sports Center covers a floor area of about 456,000 m2 (including about 322,000 m2 of venue, about 13,000 m2 of supporting R1 green space, and about 121,000 m2 of facilities for venue). The original design organization was China Southwest Architectural Design and Research Institute, and our company participated in the construction as the detailed design and construction organization
