多角度钢结构铸钢节点的研制

THE RESEARCH AND MANUFACTURE OF CAST STEEL JOINTS FOR MULTIANGULAR STEEL STRUCTURE

上海新国际博览中心是采用典型的树状钢结构建筑新理念 ,使用铸钢节点作为树状结构的连接节点的大型现代化场馆。这些铸钢节点形状复杂、要求高、质量大 ,制作难度大。主要介绍铸钢节点的设计、铸造技术要求、标准的选用、铸造及质量控制等技术 。

The new idea of typical tree-shaped steel structure is applied to building construction in Shanghai New International Expo Center,which is a large modernization building using cast steel joint as a connected joint for a tree-shaped structure.These joints feature complex shapes and sizes,high requirements,heavy weight and very difficult manufacture.This paper mainly introduces the design,the casting technique,the choosing of standard,casting and quality control of cast steel joint,which may be a reference for choosing tree-shaped steel structure of cast steel joint for large modernization buildings in the future.
