国家体育馆工程施工新技术综述

SUMMARY OF NEW CONSTRUCTION TECHNOLOGIES IN NATIONAL INDOOR STADIUM

国家体育馆屋面采用集防水、保温、装饰为一体的金属板材,外围护结构采用玻璃幕墙与金属幕墙相结合方式。钢屋架为南北曲线的双向张弦空间网格体系,构造新颖复杂,为国内首次应用。施工中通过采用钢桁架横向累计滑移就位施工技术、现浇清水混凝土施工技术、型钢混凝土施工技术等,顺利通过竣工验收,经济效益和社会效益良好。本工程已获得结构"长城杯"金奖和钢结构金奖,并完成3项国家级工法。

Adopted on the stadium roof is a kind of metal plate that has the functions of waterproof, heat insulation and decoration, while the glass curtain wall and metal curtain wall are jointly used as its peripheral enclosure structure. And the steel roof frame of the stadium is of curved two-way tensioned spacial grid system, a unique and complicated structure that has been used in China the first time, Transverse accumulated sliding installation of steel truss, cast-in-place fair-faced concrete and profile-steel concrete construction technologies were applied in the project. It was accepted and taken-over smoothly after completion, achieving good economical and social benefits. The project has won the ＂Great Wall Cup＂ structure golden prize and steel structure golden prize, and established 3 construction methods of national level.
