随着钢结构吊装技术的不断进步,多种技术的组合应用越来越广泛。我公司承建的杭州东站站房工程总建筑面积32万m2,东西向长463m,南北向宽286m,最高点距地面39.6m。承重立柱采用变截面椭圆锥管钢柱,最大长轴5.79m;轨道层采用实腹钢梁,最大截面1800mm×2500mm,外包钢混凝土结构高架层采用钢桁架结构,上铺压型钢板,浇筑
With the steel hoisting technology continues to progress, a variety of technology portfolio is more widely used. The total construction area of Hangzhou East Railway Station Building with a total construction area of 320,000 m2, east-west direction is 463m, north-south width is 286m, and the highest point is 39.6m above the ground. The load-bearing column is a variable section elliptical cone steel column with a maximum long axis of 5.79m. The track layer is made of solid-belted steel with a maximum cross-section of 1800mm × 2500mm. The steel truss structure of the outer steel-encased concrete structure is used.
