摘要
二一工程结构体系采用钢框架–劲性混凝土竖向结构。为满足工期要求,特提出钢框架先行、混凝土后跟分离技术,通过增大剪力墙核心筒钢骨柱截面尺寸形成稳定钢框架体系,满足钢框架与竖向结构分离施工的承载力要求,保障了现场的施工进度和工期要求。
The 21 project adopts longitudinal steel frame-steel reinforced concrete structure. To satisfy the construction schedule, the technique of steel frame construction before concrete releasing was proposed to form a stable steel frame system by enlarging the sectional size of shear wall core tube steel column and to satisfy the requirements of steel frame and longitudinal structure releasing construction for bearing capacity. The construction schedule was successfully guaranteed.
