【摘要】 国家会议中心工程分为会议区和展览区两个部分,每个部分钢结构形式均为大跨度桁架形式,为了能更好的满足现场的安装精度及设计要求,对大跨度钢桁架的加工工艺从选材到拼装到焊接及成型后的预拼装进行了严格的控制。更多还原

【Abstract】 The National Conference Center Project is divided into conference area and exhibition area,in which steel structure is large-spanned truss.In order to better meet the site installation precision and design requirements,fabrication process was strictly controlled,from material selection,assembly and weld to pre-assembly after fabrication.Discussion is given to the fabrication technology of large-spanned steel structure.更多还原
